Installation of camera position in parking management system

Several issues concerning image acquisition in parking lots The parking system adopts image recognition technology to manage the vehicles. When the vehicle enters or exits, it captures one frame of images and compares them. Some identify the situation of the entire vehicle. , Including the car's license plate, models, colors, and even the driver, this is done manually; some of the captured image processing, identification of the car's license plate, can be automatically processed by the computer. In short, in the above two kinds of judgments, special requirements have been put forward for the collection of images: the image is stable and reliable.

The stable and reliable image means that the image captured by the camera has good definition and stable sensitivity when the vehicle enters or exits the parking space. The high clarity helps to identify the license plate, models and even the driver, stable sensitivity, help identify the color of the car or even the old and new car.

There is a problem with the open-air parking lot: the light outside the field is particularly strong during the day and weak at night; the indoor parking lot is illuminated by lights, and at the exit of the parking lot, the amount of light changes is also large. In addition, car lights also affect the image acquisition. Based on the special requirements of the image recognition system of the parking lot system, combined with practical engineering experience, we have fulfilled the following solutions while satisfying the technical requirements:

1, the choice of camera: Select 480TVLine, with high-speed electronic shutter (1/50 to 1/10000 seconds), AGC, BLC camera function. We recommend using Sony's SSC-DC398P, SSC-DC58AP or Panasonic's WV-CP470 or similar cameras.

2, the choice of lens: 3.5-8mm with automatic aperture lens. The best choice is Computar, Seiko and other brands. If you use a manual iris lens, when the light becomes strong, it will lead to excessive exposure of the body, when the light weakens, it will lead to lack of body exposure; image information can not be accurately identified.

3. Installation of the camera: Set the position of the camera at the upper part of the parking card, select the position of the camera and adjust the angle of the camera to minimize the backlight, and also consider the camera angle of the license plate.

4. Add a floodlight with a color temperature of 3200K above the parking card to ensure the illumination of the body and license plates to ensure the stability of the image. If you select a lamp with a color temperature lower than 3200K, the image will turn blue; if you select a lamp with a color temperature higher than 3200K, the image will turn red. Turn floodlights off when there is plenty of light, turn on floodlights when light is low, and save on electricity.

5. Make some adjustments to the distance between the lens and the shield glass. According to the slope and the length of the parking entrance lane, the distance between the lens and the shield is adjusted to determine the camera's angle of view and minimize the back light interference.

Research Progress of Superhydrophobic Functional Coating Materials

Recently, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences constructed a superhydrophobic surface functional coating material with micro/nano structures on the surface of metal materials such as aluminum, copper and steel by using a simple, economical and practical method for preparing composite organic coating materials. The solution to the key technical problems in the application of super-hydrophobic coating materials in engineering applications is complex and practical engineering is difficult.

The project team used polytetrafluoroethylene and polyphenylene sulfide composite polymers to construct a superhydrophobic coating with a low surface energy hydrophobic group and a porous network micro-nanostructure on the surface using a one-step film-forming method. The coating has excellent super-hydrophobic properties, high bonding strength with the substrate, acid and alkali resistant medium, high temperature resistance and long-term stability, and lays the foundation for the engineering application of super-hydrophobic organic coating materials.

The Lanzhou Institute of Chemical Physics began research on low surface energy organic coating materials in the 1990s. In recent years, progress has been made in the preparation of surface micro/nanostructures and hydrophobic properties of engineering materials, and has been applied for and obtained a number of Chinese inventions. patent.

The series of research work was supported by the National Natural Science Foundation of China and the "973" project of the Ministry of Science and Technology.

The Artistic Charm of Love Graphics in Print Advertising Design (II)

2 Creative elements of love graphic in print ads

In the design of performance techniques, designers have different ways and ways of thinking, but romantic art expressions of love from the point of view of most of the creative experience, are generally related to love hints, can be divided into the following categories:

2.1 Abstract Graphical Creation Elements

Abstract graphics can be divided into text graphics and non-text graphics:

2.11 Text Graphics Creation Elements

Among the textual graphic design elements, the Chinese and English elements are the first. Chinese is also called Chinese characters. Chinese characters are the traditional cultural heritage of China's 5,000-year history. Text is one of the best graphic elements for accurately communicating information. Designers usually design creatively from the "righteousness" of text. 3 Here are some examples of the use of text graphics to conceal love mesغير مجاز مي باشدes and achieve successful communication when designing ideas:




(Fig. 1) (Fig. 2) is a print advertisement for Argentine & Brasil football matches. It is a comparatively early work of the end of the last century. (Picture 1) Argentine football team defeated the Brasil football team's print advertisement poster, suggesting that the Brasil team was being fucked; (Picture 2) was a poster printed by the Brasil football team against the Argentine football team, suggesting that Argentine did not Kind of friends. (Figure 1) (Figure 2) is a bold use of English elements in the text graphics, English elements are taken from the initials of the Argentine & Brasil Condom name "A" "B", the designer clever use of the English alphabet graphic element "B" similar In the shape of the curve of the female human temple, the English alphabetical graphic element "A" is subtly divided into uppercase "A" and lowercase "a" and the uppercase "B" are combined ingeniously, but only slightly The graphic elements "A" and "a" are rotated 90 degrees counterclockwise, and the graphic design of the unexpected love relationship graphic appears. The graphic is simple and clear, and it is very visually appealing. It instantly allows the audience to understand and achieve success.

(Figure 3) (Figure 4) is a series of graphic public service advertisements that conserves resources. It is a unique way to use Chinese characters in textual graphics. (Figure 3) is a copy written by the designer with free handwritten strokes. "Although I'm short, but I'm still very strong." It almost covers the whole picture. There is a short pencil in the lower left corner. (Figure 4) Designer Using the same strokes, the same typesetting, copywriting is "I'm not the kind of cover that can only be used once", with a micro-folded portfolio. The effect of communication is as simple and accurate as the general slogan of the map, with no disclosure, no introduction, and no distraction.

2.12 Non-Text Graphics Authoring Elements

In non-text graphic design elements, in addition to text graphic design elements, any abstract thing can be a design element, as long as you can find the mystery. Here are some examples of the use of abstract things to hide and express love information and achieve successful communication in designing ideas:


(Figure 5) (Figure 6) (Figure 7) is a series of graphic PSAs against ***ual harassment. They are all written in the same way. "It doesn't say anything, but you can. Don't harass the Office. *** helpline: 2106 3600." And they are all created using love gestures. (Fig. 5) is a high-level leader seat that closely follows the front and back to the lower-level employee seat; (Fig. 6) is also a state in which the two "structural engineering desk lamps" that are closely attached to each other are folded at 60 degrees and 120 degrees, respectively; (Fig. 7) It is a stack of two close-up mouse. The clever use of the series of graphics can show the designer's meticulous observation and agile thinking around the life, which is enough for the audience to see the truth. These are clever use of abstract graphics as a successful example of romantic artistic expression.

2.2 Realistic Graphic Creation Elements

In the design elements of realistic graphics, designers are not required to be exposed to sensitive parts of the human body, but instead try to substitute or try not to expose barely sensitive images. The following describes several successful cases:




(Figure 8) (Figure 9) is a series of print advertisements for VIVUNO women's shoes - Cannes Print Advertising Award winners 2003. (Figure 8) is a clever discovery, so that the aesthetically tempting graphics can be a partial close-up of the feet and thumbs of women wearing VIVUNO shoes. This discovery is as good as discovering the New World. (Figure 9) is the inverse thinking of (Figure 8). These are clever examples of successful romantic artistic expressions.

In summary, the application of romantic artistic expression of romantic love graphic in print advertising, from the effect of visual communication information, this article believes that it is a visually powerful performance technique that can powerfully attract audiences to savor. Moreover, we can be cautious in applying the expression techniques of romantic arts to avoid the "generalization of graphics" and the development of symbolic, classical and other artistic expressions to enrich the image of this era of visual culture.

Intelligent parking system charging system barrier installation method

The barrier in the smart parking system is the guardian of the property, and the installation method and use of the barrier is also very important. In the installation of smart parking barriers, we must pay attention to many techniques. At the same time, if used improperly, it will be prone to damage. What if the smart parking barrier is broken?

Many of the owners who use Daozha are unwilling to encounter such problems. The only way to think about it is to spend some time to ask some professional people to carry out repairs, or go to the parking lot manufacturer to conduct after-sales service. This will certainly solve the problem, but it will also consume time and money. Therefore, we must pay attention to precautions. We must pay attention to the installation and use of smart parking barriers, and extend the period of use. It is not easy to be bad, so the service life of barriers will increase.

1. The installation of smart parking barriers is generally on the level of the road surface. If there are slopes, attention must be paid to the installation specifications.

2. The installation of intelligent parking barriers must be carefully checked after the line is connected. If the detection is abnormal, it must be reinstalled.

3, the installation of the barrier and the coordination of the sense coil should be well coordinated, the output of the coil should be twisted to the barrier, and the distance should be as short as possible. After the connection, dry the cement and seal the nest.

4. The ground coil can't be damaged during the laying process, but also try to avoid the joint, otherwise the gate will not normally open the gate, fall off the gate, and the vehicle will not automatically fall off and other faults;

5. The parking lot barrier system has been adjusted to the moment balance according to the length of the rod before leaving the factory. If the gate rod is lengthened and cut according to the site conditions, the spring force should be readjusted to equilibrium, otherwise the motor overheat and the reduction gear box will occur. Excessive wear;

Tips: The specific installation of smart parking barriers needs to be implemented according to the system's plan.

Parking barriers are widely used in real estate, villas, toll stations, and enterprises, etc., and play a role in the direct management of vehicles in and out of the intelligent parking management system. It is important to understand its installation method and precautions.

Anti-theft alarm system detector installation considerations

For the installation of anti-theft alarm probes, in the past, we all thought that as long as they were installed and fixed on the building according to the requirements in the manual, a little visual inspection of the orientation and proper adjustment of the angle would be fine. In fact, the installation process of burglar alarm detectors is a time-consuming and time-consuming process. Here we talk about the installation of anti-theft detectors.

Laying of pipelines

In past engineering practice, you will find that some anti-theft alarm projects have hidden dangers in the pipeline construction. The hidden dangers we are talking about here do not refer to fire hazards, but to hidden dangers of man-made destruction. At the installation site of certain detectors, we can often see the use of PVC pipe sleeves or exposed alarm detection cables. The pipeline installation height is not enough and can be reached by human hands, so these can be regarded as hidden damage to the system. Some people think that this is not important, considering that the host part of the entire system may be equipped with a tamper-proof function, and any damage system can be detected. However, this may greatly affect the working efficiency of the system, or even cause the system to be shut down for repair. At this time, the system maintenance engineer needs to devote more effort and brain power to carefully find this fault point. If it cannot be found in a short time, it will be impossible for some systems to arm the system users within the warning time, because the system will think that the failure has not been ruled out.

The use of PVC pipes or tanks for the protection of anti-theft system pipelines in certain current projects is, I think, obviously wrong. At the same time, for construction or investors, this is extremely unprofessional. Compared to galvanized steel pipes, PVC pipes are very vulnerable to man-made damage. Although it is inexpensive, it is extremely deficient in the hardness index of galvanized steel pipes. From some media, you can see many overseas engineering companies installing pictures of anti-theft alarm probes. When you look carefully at the pictures, you can see that the sheath pipe that extends from the detector is a metal hose, and the special card connector Connect the hose to the detector. The other end of the hose is connected to a fully sealed metal box. The other end of the box is connected to a galvanized steel pipe.

The hidden nature of the pipeline

In the actual installation process, especially for some new buildings. In the design and installation, the concealment of the detector pipeline installation shall be fully taken into account. When pre-embedding the protection pipe, it is still necessary to consider pre-embedding. This work can be completed by the civil construction unit when pouring concrete with the building structure, so as to ensure the concealment of the entire transmission path to the greatest extent. At the same time, it should also be considered that the pre-buried pipe can be easily and conveniently connected with the main bridge, so that a small diameter steel can be pre-placed in each jacket pipe so as to facilitate the use of the threader later. cable.

Two of the cores are used to connect the detector power supply, and the other two cores are connected to the alarm switch signal. Instead of using a six-core cable to connect the switch and the working power, the remaining two cores are used to connect the tamper signal. . If the system does not connect to the tamper switch of each detector at this time, for a thief who understands the burglar alarm system, he can easily open each time the system is in the disarming period (that is, the non-working period). The detector and its "hands and feet", it can be imagined that such a system safety factor is very low. Of course, the connection of the tamper switch cannot be said to have completed the construction of high-security protection. At this time, the cable connected to the tamper switch should be connected to the host's 24-hour uninterrupted zone terminal block. In this case, it can be guaranteed. The entire system front-end probe device is in a tamper alert time of 24 hours. Here we can think about how many anti-theft alarm projects will seriously implement this process. I think such a project will be rare.

Pre-determined installation location

Determining the installation location of the detector is also easily overlooked in the actual project. The selection process of the installation position of the anti-theft alarm detector is different from the installation position of the camera. If the handling is not good, the false alarm rate and the missed report rate will continuously increase, which will affect the efficiency of the entire system. When the engineering installer finds that the location is not ideal, there are many problems to be discovered when moving the detector installation location. First of all, the pipeline needs to be moved; if it is easier to reduce the distance of the pipeline, it is feared that in the event of an extension of the pipeline, it is necessary to face the problem of extension of the cable connection. In order to facilitate future maintenance, it must be designed at this location. A junction box, this junction box will also have a hidden danger. I think the emergence of this problem is that owners do not want to see, so early determination of the location of the detector is very critical, of course, in addition to the above issues there is a problem that we can not ignore, that is, easy to change the installation location also The building decoration will be damaged. For example, you need to move a ceiling-mounted detector installed on a decorative surface consisting of a whole piece of three-plywood to another location. This will be regarded as impossible work.

Conclusion

Anti-theft alarm system detector installation process is a complex process, due to its working principle determines the particularity of the installation, and often this is easily overlooked by everyone, and with the closed-circuit television monitoring system camera installation profit coefficient This is a far cry from technical and profit perspectives. Therefore, we can more clearly see that we must design and install a good anti-theft alarm system, we must do a good job of planning and design work.
