　　2. Background

　　Supervision places such as prisons and detention centers are an important part of the state apparatus, and they are responsible for the important missions of enforcing laws and regulations and educating and reforming. At present, China is in a period of social transformation. Due to the increasing number of detainees suspected of economic and violence, there are also many recidivists and habitual offenders.

　　Since the current period, the security situation of supervision sites and detention centers has been severe, and major and vicious supervision security incidents have occurred from time to time. Since 2009, it can be seen from the public media that hundreds of detainees in supervision sites have escaped, held officers hostage, and endangered officers. A major and vicious regulatory accident of personal safety.

　　In recent years, higher-level leading departments have successively issued documents requiring careful study of management measures and technical preventive measures to ensure the safe and stable operation of supervision sites and detention centers, especially the personal safety of police officers.

　　1. Comprehensively analyze the reasons for the occurrence of supervision accidents, and there are objective problems in the following aspects in the safety guarantee of supervision sites:

　　①The police force in the supervision places is generally insufficient, and it is impossible to realize the comprehensive supervision of the supervised objects. Due to the problems accumulated in my country's history, the proportion of police officers in supervision sites is relatively low. For detention centers, for example, the Ministry of Public Security stipulates that every 100 detainees should be equipped with 12 police officers, but at present, many supervision places do not meet this requirement. However, it is not possible to increase the police force due to the limited conditions, so that the security of the supervision site is limited by the configuration.

　　②Overtime and overpressure work by ordinary police in supervision sites has become the norm. In addition, due to fatigue, negligence and other reasons, it is easy to lead to irregular law enforcement, and artificial supervision and security loopholes often appear. Managers of supervised venues generally feel that the work intensity is high, the law enforcement risk is high, and especially the pressure to ensure safety and stability is foolproof.

　　③ There are a large number of security technologies in the supervision site, including video surveillance, infrared, access control, power grid, monitoring and other systems. Due to technical and investment reasons, the area cannot be fully covered, and there are a large number of monitoring dead spots. At the same time, the existing security technologies are passive and cannot monitor individuals. It needs to consume a lot of police force to intervene in monitoring, and conduct manual analysis or management, resulting in small monitoring scope, weak real-time performance, and poor accident prevention, often only used for post-event analysis. effect.

　　2. The specific challenges facing the management of current regulatory sites

　　①It is impossible to accurately grasp the location and number of detainees in real time. Accurately grasping the number and location of detainees in the supervision site is the primary factor to ensure the safety of the supervision site. Supervision site managers need to know in real time the area where detainees are located at any time, and whether detainees are out of control, illegally entering or leaving specific areas, or illegally approaching key facilities. At present, the means of confirming the number and location of the supervision sites are very primitive, mainly relying on the manual judgment of the disciplinary police, such as reporting the number of detainees and the disciplinary police manually counting the number of people. The detainees are constantly moving between different areas, such as from the dormitory to the factory, the venue and so on. This requires the discipline police to have a very high sense of responsibility and focus. If the discipline police officer is slightly inattentive, the detainees will easily be caught in troubled waters; and there is no way to prevent individual supervisors from concealing and covering up the detainees. Under current conditions, it is very cumbersome to keep track of where and when each detainee has been, and his or her historical activity. At night, due to safety reasons, the police were not allowed to enter the cells of the dormitory, and there was no way to make an overall roll call based only on visual inspection. In addition, the total number of people in the entire supervision site is reported by the police one by one, and the summary is very slow and not time-sensitive.

　　②It is impossible to strictly identify the detainees’ identities without error It is difficult to guarantee that there will be no mistakes, because it is impossible for people to concentrate for a long time, this is an objective physiological

　　rules. The detainees are all bald and wear the same clothes. After a long period of detention, it is very easy to be mistaken. If there are twins with the same name and surname at the same time, it will be even more troublesome. There have been mistakes in individual supervision places where detainees with the same name and surname were mistakenly released, and people with the same name and surname were wrongly recorded when consuming.

　　③The means of reporting and alarming are not concealed, which is inconvenient. At present, the police mainly rely on the abuse reporting device on the wall of the prison room to report. However, under special circumstances, the detainees dare not press the reporting device publicly; when the detainee is attacked, there may be no way to press the reporting device; the detainee suffers a heart attack at night, and there may be no way or time to press the reporting device on the wall. . In addition, there is a lack of a safe and timely reporting method for relevant personnel such as ears and eyes, and it is difficult to balance efficiency and protection of ears and eyes.

　　④ It is very difficult to monitor the temporary outing of detainees. Temporary outings, such as medical treatment, identification of exits, etc., are the links with the highest probability of escape of detainees. At present, they mainly rely on police force and equipment, and there are no other technical means to assist. At the same time, as soon as the detainees leave the prison, the leaders of the supervision facility can only check the situation by calling one by one, and they are often very passive when they learn that the accident happened.

　　⑤The efficiency of mobile alarm is not high. According to the needs of work, the supervision site needs to know whether the policeman is on duty, and it is necessary to know the location of the policeman in real time. In the event of an emergency, the nearest police officer can be arranged to deal with it. At present, it can only be searched one by one through intercom and video surveillance, which is not efficient enough. At the same time, when the police encounter an emergency, they can only call for help through the walkie-talkie at present, and there is a lack of a hidden alarm method.

　　⑥ Temporary staff will often encounter installation and maintenance work of equipment or systems without accurate monitoring of their entry and exit. They need to ask external personnel to deal with them. They enter and leave the supervision site more frequently, and currently, the scope of their activities is mainly supervised by the police. If the police fail to supervise in real time, temporary staff may enter and exit places that should not be entered and exited. Meetings such as lawyers, procuratorates, family members, etc., are not managed effectively and accurately. There is no way to judge whether the police are accompanied or not, and whether the meeting is overtime.

　　⑦Consumption manual bookkeeping is inefficient and error-prone. In the process of consumption, manual bookkeeping is often error-prone and labor-intensive. Some supervision places have a tip card, but they are afraid to issue the card to the detainees for fear of accidents, resulting in the system being useless.

　　3. Summary

　　Therefore, in a very special environment such as a supervision place, how can we use technical means to more effectively monitor individuals and specific areas of individuals under supervision, so as to more accurately and controllably prevent detainees from escaping, suicide, sudden death and other unexpected situations? Under the circumstance that there are too many video surveillance probes and limited monitoring manpower, so there is no reliable technology to improve it? Is there a more advanced, efficient, economical, practical, active early warning, and precise management technical solution? How to adopt In order to truly create a cost-effective and high-efficiency scientific and technological police force project? In reality, there is a strong and urgent need for security protection, and a relatively satisfactory answer must be found in the face of the above problems. In order to effectively strengthen the safety of the supervision site, it is necessary to achieve automatic, full coverage and active monitoring in terms of security technology to realize the management of individuals. When an abnormal event occurs, the police officer can actively alarm at any time, reminding the police force to intervene in the analysis and take corresponding measures. Measures to completely eliminate the occurrence of major and vicious supervision accidents in supervision sites.

　　4. Construction goals

　　Informatization construction is for business services. First of all, it must meet the two points of effectiveness and practicality, and secondly, it should not add too much workload to the existing personnel, whether it is learning, training or daily police use. In addition, considering the special circumstances of the supervision site, the police and detainees cannot be harmed or risked during construction and actual use!

　　①Ensure the strict implementation of norms and systems, and achieve more active and refined management. Real-time positioning of all police officers and detainees in the entire supervision site or even going out, achieving automatic, full coverage, and active monitoring, and being able to record relevant trajectories. At the same time, by setting up relevant alarm rules, alarm prompts are given to some behaviors, such as detainees entering areas that should not be entered, and the police not patrolling according to the prescribed routes. All of these systems are automatically documented, traceable and auditable to ensure that relevant norms and systems are strictly enforced. Even through the analysis of individual behaviors, early warnings and alarms for police officers and detainees’ violations can be realized, turning passive into active, to prevent the occurrence of major and vicious supervision accidents in supervision sites, and to make management more active, more refined, and more effective.

　　②From passive to active security, the hidden active reporting and alarm functions are added. At the same time, by setting relevant alarm rules, alarm prompts are given for some behaviors, such as detainees entering areas that should not be entered, and automatically calling and finding their lost alarms, etc. These alarms are all alarms. It can be linked with video to completely solve the problem of monitoring without control, and turn passive security into active security.

　　③ To reduce the burden of the police, the information construction of the police force from science and technology is to serve the police, so that the police can focus more on supervision work rather than on the information system. Everything in this system is automatically sensed, and it is integrated with the existing security and access control card system of the supervision site, which truly pushes the informationization of the supervision site to intelligence and automation.

　　5. System advantages

　　According to the implementation experience, considering the special circumstances of the supervision site and the fact that active radio frequency technology is a relatively new technology, in order to better realize this system, we need to solve core technical problems such as large-scale data processing. Whether these core technical problems can be solved well directly affects whether the entire software system can achieve the ideal application effect.

　　①Safety first

　　Information security is in place. Considering that the supervision site is more sensitive, information security is very important. The entire system adopts a dedicated wireless radio frequency protocol and a special encryption algorithm, avoiding the use of WIFI and other general protocols. Possibility of accessing the internal data network of the regulated premises.

　　For human safety:

　　The radio frequency signal receiving base station itself only accepts signals in this frequency band and does not send any other signals, and the radio frequency signal generated by the radio frequency electronic wristband positioning tag on the human body fully complies with the national electromagnetic radiation protection regulations (GB9175-88, GB8702-88), and at the same time , The identity electronic identity adopts special anti-skin allergy materials, and has passed the relevant national tests to ensure that wearing it will not cause skin allergies.

　　②Ensure system reliability

　　Stability and reliability are the biggest challenges. Frequent false negatives and false positives are absolutely not allowed. Base station deployment redundancy is designed to improve reliability. When deploying radio frequency signal receiving base stations, try to consider redundancy to ensure that the signal sent by any radio frequency electronic wristband positioning tag can be simultaneously received by multiple radio frequency signal receiving base stations. This ensures that in the event of individual radio frequency signal receiving base station failures, all signals sent by the radio frequency electronic wristband tag, such as heartbeat, positioning, alarm, and low battery signals, can still be reliably transmitted. For the roll call and positioning of a large number of people, the main communication frequency uses a special ultra-high frequency communication frequency, which has strong diffraction and penetration capabilities, ensuring that the radio frequency electronic wristband positioning tag is placed in any position, any direction, or It can be read reliably even when the detainee consciously blocks it with his body. At the same time, we have solved the problem of long distance, large flow, and ultra-low power consumption well, and fundamentally improved the performance of the product. This ensures that the system can effectively reduce the collision rate of radio frequency positioning signals in the air under the condition of high-density positioning of radio frequency electronic wristband positioning tags, and greatly reduces the probability of radio frequency signal reception loss. In the case of a large number of radio frequency electronic wristband tags, it can reliably receive the signal of each electronic wristband positioning tag, ensure the reliability of key signal transmission such as police officers, detainees' roll call and alarm, and fully meet the key requirements for the safety of supervision sites. .

　　③Precise positioning

　　The unique two-level positioning mode greatly enhances the positioning accuracy. The channel management module can accurately determine the direction of entry and exit, effectively avoid misjudgment, and prevent the occurrence of false in and out. The electronic identity is scientifically designed and one-time plastic sealed to achieve lightning protection, waterproof, mildew-proof and impact-proof, and meet the requirements of industrial environment. The unique snap-on design makes disassembly and assembly very convenient, requiring special tools to disassemble. At the same time, the internal current loop design of the wristband positioning label can ensure that when the identity is damaged (such as cutting, button damage, etc.), the identity can send a signal to the system to alarm .

　　④High compatibility and scalability

　　In the future, more applications such as asset management, vehicle management, equipment management, etc. can be directly and quickly deployed on the existing platform. Reserve interfaces with security, office, application business and other systems, which can be quickly integrated and form a joint force.

　　⑤ Integration with other systems

　　Multi-card integration, the system uses rfid radio frequency technology to realize identification, positioning, and tracking, so it can be seamlessly integrated with other rfid radio frequency equipment in the supervision place. Realize the following functions: The electronic identity of the detainee can also be integrated with the detainee card at the same time, which can realize the integration with the detainee's relatives meeting, pocket money consumption and other systems, so that the detainee can directly use the electronic identity to meet, register, swipe the card and supervise the daily routine of the place. Consumer swiping cards make electronic identities a component that detainees need to use on a daily basis during their sentence, reducing the resistance of detainees to wearing them, and preventing detainees from deliberately damaging their electronic identities. The radio frequency positioning identification card of the police officer can be integrated with the radio frequency system such as the access control and patrol inspection of the police officer card, so as to realize the integration of multiple cards. It is seamlessly connected with the supervision business platform, and the interface between the system and the management information system of the supervision site can be based on the specified data interface standard, based on the SOA architecture, and provide a two-way interface of data acquisition and data service in the form of WEB services. Interface with various existing supervision site management information systems in supervision sites, mainly including obtaining basic information such as radio frequency positioning identification cards and electronic identities associated with police officers, detainees' names, genders, photos and other basic information from the existing supervision site management information systems Data, management data such as the grade treatment of detainees. The information of detainees and police officers can be accessed at any time in this system. Maintenance is convenient. The system should provide automatic maintenance functions for electronic identity and positioning equipment. For other radio frequency signal receiving base stations, it should provide maintenance functions such as fault detection and software network upgrade to reduce system maintenance costs.
