In recent years, with the changes in the structure of prison inmates, prison conditions and prisoners in China, the prison security situation is more severe, and the pressure on security precautions is increasing, prison security is the primary standard premise for prisons to achieve their work policies, and maintaining prison security is a large-scale system project, and it is necessary to comprehensively use civil air defense, physical defense, technical defense and other theoretical means to build a long-term and effective prison security system to ensure the long-term peace and stability of prisons. The implementation of important instructions such as "strengthening the police with science and technology" and "asking for police force from science and technology" has attracted more and more attention from the prison department, and the content of prison security technology prevention work is complicated and the responsibility is heavy, mainly including the control, handling and providing information on preventing prisoners from violently attacking the police, taking hostages, escaping from prison, forcibly rushing into prisons and other incidents, etc., which play an increasingly important role in ensuring prison safety and maintaining the stability of supervision order.
Prison wall perimeter invasion Prison escape protection system is composed
The perimeter anti-crossing alarm system consists of the alarm receiving computer, the alarm host, the perimeter detector and the signal transmission part of the prison to form the alarm network structure. When the prison perimeter is illegally crossed, the detector can immediately transmit the police information from the bus to the prison security management center, and at the same time link the ** monitoring system to monitor the police situation, and the prison management center will display the crossing area on the electronic map, so as to facilitate the timely and accurate handling of security personnel. Its functional requirements are as follows:
1.The perimeter must be fully fortified, without blind spots and dead ends;
2.The detector is resistant to adverse weather environments and has strong interference ability;
3.The division of the defense zone is suitable for accurate positioning when alarming;
4.The prison management center identifies the alarm area through the display screen or electronic map;
5.Alarm the scene of the climbing area, and at the same time issue a voice siren alarm lights and warnings;
6.The prison management center can control the recovery of the status of the front-end equipment, such as false alarms or the completion of accident handling;
7.Alarm status, alarm time recording and printing of the alarm center.
Application advantages of the flagship laser intrusion detector prison perimeter alarm system
The flagship laser intrusion detector is the [fifth generation] flagship laser detector created by the high-end brand "Viandas" laser technology R&D team of Guangzhou ALEPH Electronic Technology Co., Ltd. after 18 months of hard work, after more than 40 program updates and more than 100 outdoor field tests! The fifth-generation flagship laser beam detector can achieve up to 144 beams working in different codes on a detector, and each beam does not interfere with each other, and each beam can achieve accurate identification and alarm, and the product has a number of patented technologies to fill a number of industry gaps. Due to the high intelligence and stability of Viandas flagship laser beaming, as well as the convenience of being able to achieve accurate beam alignment at extremely fast speed, the flagship laser beam won the Golden Tripod Award of the 17th CPSE Expo and the 2019 China Smart City Recommended Brand Award.
Rugged appearance, impact resistance, external force damage and harsh weather influences.
The perimeter equipment of the prison system should take into account the damage of the equipment, explosion-proof equipment is required, the performance of the Viandas laser beam is stable, the whole is made of stainless steel, the mechanical structure of the system is precise, the laser system and optical components are processed according to precision instruments, the internal structure is stable, the system is installed firmly and reliably, the shell of the laser intrusion detector is all made of stainless steel, fixed on the cement foundation, in addition to the protective cover against wind and sand and rain, In addition, the base with an increased width can minimize the influence of external force and effectively isolate the influence of strong winds on the structural stability of the system.
The laser has strong anti-interference and stability.
The application of a new generation of anti-interference technology of laser beam detector makes the normal operation of the equipment not affected by the natural environment, even in the strong light environment of 50,000 illumination, it can work normally, whether it is rain or snow, or even haze and dust weather, the product can also work normally, which greatly enhances the stability and reliability of the product.
It supports normal operation under strong sunlight, and supports normal operation in a relatively harsh environment - 40 degrees to +70 degrees Celsius, without false alarms, and the product can be used in any place on the ground at home and abroad.
Ultra-low false positive rate
Viandas combines the professionalism and precision optical application design in the alarm industry, so that the transmission and reception of laser through-beam products become safe and reliable, and it is not easy to produce false alarms.
How it works. A laser transmitter is arranged at the beginning of the prison fence or the warning area close to the fence, and a laser receiver is placed at the end, and the directional strong laser beam emitted by it is directly shot to the receiving end, and the received optical signal is converted into a switching signal through an optoelectronic device at the receiver, and processed by a discriminator. When the confirmation signal is normal, the blue light is turned off inside and the monitoring state is maintained; This enables monitoring of the entire distance traveled by the laser beam. When there is an intrusion or intrusion when the beam is blocked, the signal shows that the blue light is lit, and the alarm signal is output at the same time, and the alarm signal is transmitted to the alarm control host of the back end, and the host can identify the alarm area and the precise defense area and position, and can assist the linkage function of monitoring to monitor the screen of the alarm situation.
