Analysis of Emergency Alarm System Used in Prison Security Field

According to relevant information released, there are about 7,000 detention centers and more than 13,000 prisons in the world. Among them, there are nearly 700 prisons in China and nearly 2 million people are serving prison sentences. In recent years, various kinds of escapes and assaults on police have occurred at home and abroad, which has greatly affected the stability of public security and the safety of people’s lives and property. Therefore, in the rapid development of the national economy today, the management technology and management level of prison custodial supervision are also increasingly demanding. The use of modern high-tech means can effectively protect the security of prison officers and the handling of emergencies, give full play to the role of the alarm system, and achieve alarm assistance and early warning in emergency situations.

The ultimate goal of the supervision work is to increase the emergency capacity for emergency incidents, improve the efficiency of police officers and improve the quality of crimes. Therefore, in the implementation of the project, it is necessary to focus on the development and transformation of the security system integration, emergency response plans, and intelligent early warning functions, and to play a role in improving the supervisory security factor and the quality of education.

In view of the current special requirements for the prison warning system, taking into account the complexity of the personnel structure in the labor reform zone, especially the personal security issues of the civilian police is a top priority. Looking at the advanced and successful cases at home and abroad, and combining with the actual situation of the prison, we plan to adopt the telephone network alarm, which consists of an alarm front end and an alarm receiving center. We will make full use of the existing public telephone network in an economical, reasonable, and applicable principle. Resources, reduce wiring costs; system expansion is flexible and convenient and low cost.

The introduction of the alarm work Here, we take Zhejiang XX prison as an example. The advantages of this system are as follows:

· Low cost, good cost performance using the system: the system networking lines use telephone network lines and prison internal virtual network;

·Good stability: The networking software and platform software have undergone long-term development and improvement;

Scalability: As long as there is a local telephone network can be directly accessed;

· Convenient construction, advanced technology: no additional wiring, reliable transmission network.

System Composition The system consists of a front-end emergency alarm button, an alarm control panel, an alarm receiver center, a management workstation, and a PSTN telephone network (using existing telephone lines in each substation).

The receiving center host receives various events such as alarms, withdrawals, and recovery from the alarm front of the sub-zones. It handles alarm events and monitors other events to ensure that the front-end controller works normally, ensures safety, and avoids or minimizes. Occurrence of special events. It uses digital signal processing technology to receive and analyze various types of alarms and monitoring data, and it has received various popular alarm communication formats that are compatible with most alarm controllers on the market. Because this machine is based on the microprocessor platform, it has stable performance, powerful functions and fast speed, and adopts programmable read-only memory technology (FLASH).

EPROM), downloadable upgrade software for instant addition of functionality.

The alarm center is composed of various workstations with different functions, and together they complete a series of work such as alarm receiving, processing, forwarding, and management.

System Implementation This solution uses one set of alarm receivers and is placed in the management center; one set of eight zone alarm control hosts (with wireless reception) (including LCD keyboards, wireless remote controllers, etc.) and one emergency button per subzone.

When the police in the sub-supervising area manages to attack the police, anomalous movements or emergencies, the wireless remote controller or emergency button at the scene is pressed to send an alarm signal to the alarm receiving center. The alarm receiving center system interacts with the prison security management platform through the interface module. In the system, the prison watch center automatically switches to the video surveillance image of the alarm area, and pops up emergency plans and other disposal measures and sends a short message to relevant responsible persons and leaders in charge. At the same time, the alarm scene sound and light alarm activates to remind all management police on the scene that there is an emergency situation. occur.

The alarm center system software shares the data to the prison security platform software through the interface, which involves the secondary development of the software interface and requires the cooperation of the two vendors in order to achieve sharing and integration.

At present, this case has been successfully implemented in Zhejiang XX Prison, and the use effect has reached the expected design requirements.

The prison is the place where criminal suspects and prisoners are detained. Because of their special nature, they also have special requirements for the alarm system. The use of modern high-tech technical means can effectively protect the security of the prison guards and the occurrence of emergencies, give full play to the role of the alarm system, and achieve alarm assistance and early warning in emergency situations.
