The official entry into force of this announcement will have a major impact on the inspection and customs clearance of imported waste raw materials at various ports. According to relevant national laws and regulations, it is forbidden to import solid wastes that cannot be used as raw materials or can not be used in a harmless manner. Imports of solid wastes listed in the Catalogue of Imports of Solid Wastes are prohibited; restrictions are imposed on solid wastes that can be used as raw materials. Import and automatic license import classification management. It is understood that according to the new Catalogue of Prohibited Imports of Solid Waste, a large number of “used waste plastic bags, membranes, and nets” imported into China have been adjusted into the “restricted list of solid wastes that can be used as raw materials for import”. The list of imported solid wastes is prohibited from importing.
Lianyungang Port is a traditional port for the import of solid waste. In 2007, a total of 210,000 tons of waste raw materials were imported. The main varieties are: waste paper, scale, waste hardware, waste plastics, etc., mainly from the United States, Canada, Japan and other countries. Among them, Lianyungang Port imported more goods such as waste plastic bags, nets, and membranes (accounting for 60% of the total import volume of Lianyun Port), and was adjusted from the “Catalogue of Imported Solid Wastes that Can Be Used as Raw Materials” to “Forbidden Imports of Solids”. Waste Catalogue.
To this end, Lianyungang Inspection and Quarantine Bureau reminded that since March 1st, the inspection and quarantine authorities have begun to accept inspections for new solid waste import licenses that can be used as raw materials. Related importing companies should do a good job of importing solid wastes. "License" to apply for replacement, to avoid causing economic losses.

With the purchase, installation and commissioning of security doors, the entire process is relatively flexible for the user. However, how to ensure the maintenance of the security gates and the maintenance of the security gates has given rise to many companies and agencies. Do not know where to start. Below, we will mainly introduce you to some matters that need attention in the post-maintenance of the security gate. For the normal operation of the security gates, as well as long-term use, do a simple pave.

The first thing to say is that, in the re-use of security doors, first of all, they should be away from large metal or magnetic objects. This is what we want to pay attention to. The security door itself is a device that uses the magnetic field effect to detect metal objects. If a metal object is placed around it for a long time, uninterrupted false alarms will be triggered, which is not necessary for us. Then there is the life span and age of the equipment. When it exceeds the established working life, it will be scrapped. If there is a large magnetic object next to it, it will seriously affect the normal operation of the security door. It is recommended that you do not want to prevent large magnetic objects around.

The second point is rain protection. Some users in this area do not have to worry about it. The main reason is that they are all used to make our security doors in Xi'an. If you are not outdoors, naturally you don't need to consider this one. You should pay more attention to this, as opposed to the plant and the public security gates of the prosecutors and prisons. If you buy a rainproof security door, you must pay attention to this. Then you do not have to consider fruit. If it is not rain-proof, it should be far away from the accumulation of water or rain, and the security gate should be properly shielded. To prevent the chassis circuit board from burning out. Give you unnecessary trouble.

The third point is that there is no fixed security door, and there must be a special person next to the guard. Prevent the passing of personnel from being overcrowded, causing damage to security doors. So that the security door does not work properly. The fourth point is our day-to-day cleanup and maintenance of the security door surface. In accordance with the maintenance methods of general electronic equipment, we regularly check the security door panel and the mainframe, and whether the power supply wiring is loose. If there is a new fix in time. There is dust and dirt on the surface. In order to ensure the maximum efficiency of security doors and the most useful life.

The last thing to note is that there are still many details that we should pay attention to when using the security door. For example, when a person passes through, they must stick to a single pass. Don't let many people pass through at once and there is a mobile security door. The best place to use is to be flattened to prevent accidents, etc. These are all issues that we should pay attention to, but not every user will encounter it, so our security door in Xi'an again reminds security checkers to use Personal, if you encounter any problems in the use of security doors, you can not handle it, it is best not to unauthorized start the maintenance, contact us quickly after the staff to achieve the fastest and best after-sales service.

ETC Electronic Toll System is a high-tech intelligent transportation electronic system that integrates microwave wireless communication, image recognition, automatic control, sensing technology, computer network and information processing, etc. It is automatically installed on the road side through vehicle-mounted electronic tags or The microwave antenna on the gantry exchanges information so that the vehicle can automatically collect road tolls without stopping. This article focuses on the working principle, system composition, system functions and workflow of the expressway ETC electronic toll collection system.

1 Introduction

With the continuous growth of expressway network toll collection and continuous increase of traffic volume, the problem of vehicle congestion and environmental pollution at expressway toll stations has become increasingly prominent. How to improve the capacity of clearing and the processing efficiency of lane tolls is imminent. ETC electronic toll collection system uses microwave radio communication, computer network and information processing, image recognition, sensing technology, automatic control and many other high-tech means to automatically use vehicle-mounted electronic tags and microwave antennas installed on the roadside or gantry. Information exchange enables vehicles to automatically collect road tolls without parking. Vehicles that pass through toll stations without stopping can significantly increase the toll station's capacity, reduce fuel consumption and exhaust emissions caused by queuing and payment, and greatly improve high-speed The traffic conditions of the highway greatly promote the development of highway toll management.

2. Overview of ETC Electronic Toll System

ETC electronic toll collection system is a kind of intelligent wireless high-speed communication, computer network and information processing, image recognition, sensor technology, automatic control and other high-tech applications in the highway toll system, to realize the automatic charging of vehicles without parking. Transportation electronic system.

ETC electronic charging method has the advantages of full-automatic, fast and convenient, non-cash transactions, large capacity, etc. It utilizes vehicle-mounted electronic tags to automatically exchange information with microwave antennas installed on the roadside or gantry, and controls the computer according to the insertion of electronic tags. The information stored in it identifies the road user's information, and it automatically completes the charging process without the need for driver parking and other payroll operations. Compared with the traditional MTC system, ETC system has the following characteristics:

(1) Effectively improve the traffic capacity of the toll lanes and speed up the charging rate; (2) Reduce the loss of mechanical parts caused by brakes, reduce fuel consumption, and reduce vehicle exhaust pollution; (3) Multiple card-based toll stations for convenience Drivers; (4) System management is simple, work is safe and reliable; (5) The toll of corruption in the toll collection work is eliminated.

3, ETC electronic charging system works
ETC electronic toll collection system mainly utilizes automatic vehicle identification technology to identify "electronic tags" of on-board units (OBUs) on the vehicle through the signal transmission and receiving device (RSU) of the control system on the roadside or gantry. The information stored in the electronic tag identifies the basic information of the vehicle, and the toll is deducted from the owner's bank account or stored value according to the driving condition of the vehicle. After the transaction is successful, the lane railings are automatically lifted and the vehicles are released; after the vehicles pass, the railings are automatically lowered. The entire process does not require manual intervention and the vehicle does not stop to pass quickly through the ETC toll lane.

4, ETC electronic charging system composition

The ETC electronic toll collection system mainly consists of ETC toll lanes, toll management systems, ETC management centers, specialized banks and transmission networks. According to the division of labor, the system can be divided into two parts: the front-end system and the back-end system.

The front desk mainly implements parking fees through the ETC toll lane system. ETC lane equipment mainly consists of antenna, antenna controller, trigger coil, snap coil, drop rod coil, automatic barrier, traffic light, flash alarm, lane computer, lane controller, fee display (with balance display function), lane Cameras, character overlays, fog lamps, license plate recognition systems, etc.

The background system consists of toll management subsystem, ETC management center and professional banks. It is responsible for background ETC transaction data service, operation parameter management, and system operation monitoring. Through the data interface software, ETC electronic charging system and network charging are realized at the station level. System data processing work. The ETC Management Center is the top management of the ETC system. It not only handles the processing and exchange of charging information and data, but also performs the necessary management functions. The back-end system conducts transactions, account splits, and financial settlements between highway companies and users based on the data files received. It is equipped with powerful computers to collect and process various data and images in the system.

5, ETC electronic charging system function

(1) Detecting the vehicle's exit, departure, and counting of vehicles, transmitting the test results. In combination with vehicle identification, it can determine whether the vehicle has an electronic tag (OBU); (2) It has real-time image capture and license plate recognition functions. When the vehicle passes through the lane, the capture device automatically captures and saves the image of the vehicle, identifies the license plate number and saves it; (3) Writes information on population toll stations, vehicle models, etc. into Sutongka information in the population lane; Calculate the toll amount for the toll stations and rates etc. that the vehicle passes through; (4) Correctly control the lane equipment actions according to the lane computer control instructions, including the automatic railings rise, the traffic light switch, the alarm switch, and the fee display. Display, switching of the greenhouse lamp, etc.; (5) Complete the data exchange between the lane and the toll station. Including receiving information from the toll station, uploading the original toll data of Sutongka, and passing information of the population lanes; etc. (6) If the vehicle passes through the ETC lane, an anomaly will occur. The vehicle-to-system will intercept the vehicle and the vehicle will not be allowed to pass. No longer out of the vehicle, the toll station staff led to the next MTC lane.

6, ETC electronic charging system workflow

(1) When the vehicle equipped with an electronic tag enters the communication range, it is first pressed to the trigger coil buried in the ground to activate the read-write antenna; (2) The read-write antenna communicates with the electronic tag, and the electronic tag emits the electronic tag in a microwave manner. And model code, read/write antenna receives and discriminates the validity of the electronic tag, if the electronic tag is valid, the transaction is performed, if it is invalid, the alarm is reported and the lane is closed until the vehicle leaves the detection coil; (3) For vehicles with invalid cards or no cards If it follows the car in a toll lane, the reader antenna will activate the fast automatic railing, close the toll lane, and intercept the rushed vehicle on the spot. (4) If the transaction is successful, the lane control rails will be lifted, the lane traffic lights will turn green, and the transaction information will be displayed on the fee display; (5) When the vehicle passes the snap coil, the system will perform image capture, and the character superimposer will superimpose the vehicle information to In the captured image; (6) After the vehicle passes the drop rod coil, the railing automatically falls back and the traffic lane traffic light turns red; (7) The system saves the transaction information and uploads it to the toll booth server. A charging process is completed and the next vehicle is waiting for entry.

7. Conclusion

With the increase of networked toll roads, compared with MTC, the advantages of ETC tolls have become increasingly prominent. However, current ETC electronic toll systems still have problems with communication technologies, follow-up interference, unsuitable trucks, false alarms, and high investment غير مجاز مي باشدts. , and the problems of incomplete ETC technical standards, different key system standards, and different networked toll management mechanisms between neighboring provinces, with the continuous improvement of communication technology and inter-provincial ETC technology, ETC electronic charging system will rely on its Incomparable flexibility and extensibility have been widely promoted and applied in highway toll management.

Campus Card uses computer technology, network technology, and communication technology to comprehensively digitize all information resources related to educational administration, school affairs management, and life services, and uses scientific and standardized management to integrate and integrate these information resources to form a unified User management, unified resource management and unified access control.

At present, the Changzhou campus of Hohai University has applied a relatively mature and professional application management system, such as library management system, educational management system, financial management system, computer room management system, electronic control management, and some professional manufacturers. In some aspects, more mature application systems have been developed. In order to protect the pre-investment of schools and the smooth upgrade of the system, inter-system interconnection, data sharing, and elimination of information islands must be implemented with the "campus card" system. Docking extensions.

First, based on the "campus card" system scalability

Extensibility design is one of the principles of the "campus card" system design. The scalability of the "campus card" system's internal system includes the following aspects:

(1) Extensible design of card applications. The "campus card" system uses the card directory manager to uniformly plan the user unit card structure. In addition to cardholder's unified identity authentication information, personal basic information, and wallet information, the rest of the card can be defined in the "Campus Card" system card directory manager, unified management, and achieve the custom requirements of spare sectors. For example, in the campus card, you can define a shower wallet, a control wallet, and a library card information through the card directory manager to meet the different requirements of different application subsystems.

(b) The extensibility design of the terminal product. All terminal products of the campus card system adopt the modular design concept of 1+X. It adopts the principle of embedded design and adopts a unified hardware and software platform. It provides different functions and business modules for different environments and business requirements. Terminal equipment of different nature of business. Online downloading to the corresponding terminal product update application via the network does not require opening the lid to replace the application chip.

(c) Extensibility design of network products. All network products use international standardized products to ensure common use and expansion. The backbone network uses the campus network, and campus outlets can be used directly to facilitate access and expansion. Subnet lines are designed in accordance with the standard local area network star structure. The terminal products are isolated from each other on one bus. Increasing or decreasing the number of terminal products will not affect the terminal products that are already in use and ensure scalability.

(d) Extensibility design of software products. Application software products adopt three-layer structure design and development, standard modular structure design, integration, split, and maintenance are very convenient. Users can define and organize these standard modules by themselves and use the “software interface generator” equipped with them to quickly form New application management system. The software system adopts the "1+X" application mode, which provides a simple, fast, and convenient condition for the development of a new extended application system (X) on the basis of a common module platform. From the software upgrade aspect, because the software is centrally installed in the application server, the local upgrade implements the "hot-plugging" technology of the functional modules. The upgrade does not affect the normal operation of the system and brings great convenience to the software upgrade [2].

Second, based on the third-party application system docking extension (a) extended docking logic diagram

The "campus card" system provides third-party docking methods based on the principle of open standards: data level, functional level, and business level. Business data is the core of the campus card system. The campus card data is divided into three types: public data, private data, and sensitive data. According to three different data types, the campus card system data exchange platform uses XML standard protocols to provide various business data for third parties based on different security levels.

The unified presentation layer (V), business logic layer (A), data control layer (C), and data access layer (M) in the "campus card" system architecture all provide WebService interfaces based on the XML standard protocol, which can be third-party services. Layers to achieve docking [3]. The "campus card" hardware platform provides a set of docking API functions to meet the related aspects of the third-party system's hardware operation functions, as shown in Figure 1.

(II) Data level interconnection

The campus card data is classified into three categories: public data, private data, and sensitive data. The main business data of the campus card includes the original transaction certificate data, original attendance data, and transfer certificate data. Business data, business result data, and basic data of the business platform. According to different types of business data, different levels of security are used to connect data layers [4].

There are mainly three types of docking methods: metadata level, data exchange technology using open XML protocol, advanced technology, strong data interaction, high security, and high real-time performance; at the file level, the two sides define a file format for exchanging data. , Data format, mutual document import and export functions, poor real-time, file format is not easy to unify; database table level, docking is simple, data interaction, real-time, high, the database without any security protection, system dependencies.

Third, Docking Extension Based on Private Charging Machine (1) Docking Network Structure

The dedicated billing machine has two communication ports, one of which (RS485 or TCP/IP) is connected to the "campus card" information management system to achieve functions such as clock synchronization, blacklist synchronization and transaction uploading, and the other (RS232 or TCP) /IP) Connect to a third-party software system to enable reading and writing of the IC card.

(B) specific functions and implementation process

The docking system call interface function completes the cardholder identification and deduction process as follows: the dedicated charging machine is correctly connected to the computer serial port (RS232) or network information port (TCP/IP); the dedicated charging machine power is turned on; the call is provided Dynamic library or use the method provided by ActiveX control; call to open the serial port function to open the serial port connected to a dedicated billing machine or establish a socket connection with a dedicated billing machine; the library management system issues a card reading command; if it is a valid card (special terminal automatic judgment ), library management system will be the user card card number and other basic personal information (ie student number, library card number), library management system according to the card number for other processes (such as borrowing, returning books, deductions and other business processes); If it is an invalid card (special terminal automatic judgment), the library management system will obtain the information that the user card is illegal or blacklisted, and the library management system may stop the other business processes of the card; if the library management system needs to deduct Fees, calling the deduction card amount function, incoming receivables amount, dedicated POS machine to automatically deduct the deduction; dedicated P The OS machine displays the transaction result information in the display window according to the normal consumption flow, such as the transaction result transaction amount, the balance before and after the transaction, and returns the transaction result information to the library management system; calls to close the serial port function to shut down the serial port or disconnect the Socket connection; terminal POS The machine uploads the transaction flow to the campus card system through the RS485 network and completes the merchant settlement process.

IV. Conclusion

The above types of docking methods are flexible and versatile. In addition, each terminal device also provides a docking interface and docking method. The third-party product provider or customer can use the application program interface API provided by the “One Card” construction unit to carry out the transformation of the original system, or The original system's source code or data structure is transformed to achieve data center data, cardholder card data (such as personal information and wallet balances), terminal product data is completely shared, and takes effect in a timely manner. There is no link trace. Since the access to the database is based on the middle layer isolation technology and the hardware encryption verification mechanism, all types of linking methods are safe and reliable, and the "one card" information of the Hohai University Changzhou Campus is implemented in the school with the shortest time and fastest speed. , Widely shared and applied.
