I. Background
Currently, video surveillance systems the detention system employed, alarm systems and access control systems are based on wired communication, which makes a number of wiring regions do not become easy to manage security monitoring Blind Area In addition, a constant monitoring area also gives criminals an opportunity. The guard house has high security and high stability and real-time requirements for its security system design. In order to prevent criminals from committing crimes such as killing, fighting, self-mutilation, and jailbreaking, they timely and accurately controlled and read information on the scenes of violence and escape from prisons, and built a three-in-one security system for air defense, physical defense, and technical defense. A wireless security network based guardian security system design scheme. Using wireless instead of wired can bring many benefits, such as reducing deployment difficulty, lowering maintenance غير مجاز مي باشدts, and increasing flexibility, especially in areas where wiring cannot be done or inconvenient. As some industry insiders said: "Innovation in wireless communications will enable more and more wired communications to be replaced."
(1) Management of outbound roads When a person in charge of guarding a house, such as seeking medical treatment, arraignment, courtroom, or transfer to prison, needs to go out, the person serving the sentence needs to wear an RFID wristband and install a vehicle-mounted positioning base station on a vehicle such as a prisoner. On the one hand, GPS location management of vehicles is conducted. On the other hand, the number and status of detainees inside the vehicle and the car guards are monitored. The vehicle-based positioning base station sends vehicle position and vehicle personnel information back to the monitoring center through GPRS or CDMA. The monitoring center can Keep abreast of the situation of the vehicles and the people inside the escort.
The portable prison guard carries the portable monitoring terminal with him. The terminal and the alarm monitor the status of the people in the vehicle in real time. When there is an abnormality in the wristband, an alarm is issued immediately to enable effective monitoring on the way out. At the same time, when the prison guards encounter an emergency, they can also send an alarm signal to the monitoring center.
(2) Out-going inquiries, medical treatment, labor, supervising operations outside the prison When detainees go out for medical treatment, labor, etc., they can quickly set up a temporary wireless mobile monitoring and positioning system at the place where they go, and conduct on-site monitoring of the staff who wear the wristband. To prevent the escape of a prisoner from going out. The wireless mobile monitoring base station sends on-site personnel information back to the monitoring center via GPRS or CDMA. The monitoring center can keep abreast of the situation of people going out through the monitoring terminal, and can take immediate measures when abnormal conditions occur.
Off-site executives can wear a GPS positioning wristband to monitor the position of the person and the state of the wristband in real time. When an abnormal situation occurs, an alarm mesغير مجاز مي باشدe is automatically sent out.
(3) Real-time monitoring of the fixed area within the custody station The monitoring of the base station is performed at the guard house and all other relevant personnel activities and through the regional deployment of the base station, and full coverage of the signal is required in the surveillance area within the guard house. Place radio frequency fences in border areas such as fences. Relevant personnel wear positioning wristbands to conduct real-time, full-scale, active monitoring of prisoners and management personnel, and provide timely alarms for abnormal conditions. Prison guards can wear wristbands to prevent attacks and automatically or manually issue alarm distress signals in emergency situations.
(d) Management of borders and access control of the guard house By arranging the base stations at the boundary of the guard house and exit gates and defining the legal action area, coupling of radio frequency fences and wrist straps arranged at the boundary and exit gates can be used to achieve close proximity to the borders and exits. Getting started wristbands for information statistics and alarm tips.
(V) Monitoring and management of external vehicles By combining the vehicle information with the card, the position of the vehicle within the guard station can be controlled by issuing the vehicle for the day-in and day-out guard station and the escort vehicle, and the vehicle position information, personnel information, and the mobile information of the vehicle at the guard station can be controlled in real time. . In combination with the GPS system, it monitors whether the outbound vehicle's walking route is traveling in accordance with the prescribed route and controls the position and status of the outgoing vehicle in real time.
(6) The asset management can manage the defensive items and important assets of prison guards within the guard house, and can achieve the statistics of the use of defense depots, the monitoring of defensive items without leaving the posts, the maintenance records of defensive items, etc., as well as the important equipment within the guard house. Position setting and status monitor (7) Linkage management with other facilities of the guard station When an alarm occurs, it can automatically switch to the video camera near the corresponding alarm site and follow the monitoring site. At the same time, it can also cooperate with the fingerprint system and the electric door to provide signals to the follow-up door in the corresponding position to control the action of the electric door.
Third, wireless video monitoring terminal equipment:
IV Summary wireless technology to be widely used in the care of the security system, the غير مجاز مي باشدt of equipment is also an important factor, the wireless communication module for low-غير مجاز مي باشدt monitoring system requirements.
Nowadays, wireless network technology is introduced into the management of the management industry, and an improved application method is proposed for the comprehensive management of the detention facility, and an overall plan and design plan for the entire management system is proposed. Under the background of the informationized construction of the monitoring station, the comprehensive use of advanced wireless network technology, computer technology, network communication technology, automatic control technology, active detection technology, digital image encoding and decoding technology and multimedia technology has realized the information of the guard house. Monitor system system function requirements.
