Anhui Province, a public security case center personnel positioning solutions

Project Background

A public security case center in Anhui Province focuses on creating high security supervision and continues to deepen standardized law enforcement construction. In this project, with the help of UWB high-precision positioning technology of the Internet of Things, the positioning system is linked with the monitoring system in real time to conduct 24-hour full-process dead-end monitoring of the suspect's activity trajectory in the case area, real-time positioning and full video recording to achieve a comprehensive standardized law enforcement process information collection and filing, law enforcement process supervision.

This not only realizes the whole process supervision of the police law enforcement activities, eliminating the occurrence of law enforcement irregularities, law enforcement objections and other problems, but also effectively prevent the occurrence of security accidents such as self-inflicted injuries, self-harm, escape of suspects, to ensure the safety of law enforcement, effectively enhance the effectiveness of supervision, and promote the rule of law further.

It is reported that the office center since its establishment last year, a total of more than hundreds of suspects examined, sent to trial, law enforcement process comprehensive information collection, without a doubtful or controversial cases.

Program establishment - high-precision positioning to help intelligent case handling

Woxu UWB case center personnel management solution mainly adopts UWB high-precision positioning technology, with2Daccuracy up to 30 cm. by deploying a certain number of anchors in the case center, for outside police officers to wear card tags, suspects, prisoners wear anti-tampering watches, can grasp the location and trajectory of personnel in real time, in case of emergency events such as prisoners escape, prisoners without vital signs / timeout In case of emergencies such as inmates escaping/inmates without vital signs/staying in the fence, the tag will vibrate/beep actively, with system prompts and voice announcements to convey timely reminders.

Because of the dense room in the case area, 0-dimensional positioning is mainly used for small rooms such as interrogation rooms and interrogation rooms to identify whether the person is in the room and view the real-time situation with video monitoring. The corridor adopts 1-dimensional positioning to sense the movement and specific location of personnel in the corridor or prison cell. In the whole project, 17 anchors were deployed, covering an area of about 400 square meters.

The personnel positioning system is also linked with all the full-coverage cameras in the area, so that the location of personnel in the case area can be visible and controllable, ensuring that all historical trajectories are traceable by video, achieving automated and active monitoring, and having relevant information recorded in the case.

Intelligent application - instantly grasp the management of each link

At present, the case center personnel positioning system has met the business needs: its application of real-time location of personnel, video surveillance linkage, virtual electronic fence, a variety of alarm modes, attendance management, etc., can achieve real-time effective supervision and management, to ensure that the implementation of refined, standardized case handling.

1)Swipe card binding

Batch entry of police officer information, fuzzy query according to name/police number. Inmate names and other information are entered manually, and ID numbers have authenticity verification. Both the officer card and the inmate bracelet can be swiped and bound.

2)Combination of real-time location and monitoring

The UWB positioning system is integrated with the video monitoring system, and the management can quickly inquire about the on-duty situation and inmate heart rate information.

3)Historical track replay

The activity trajectory of personnel within one year can be queried, and the trajectory of a single person or multiple people in a certain area can be queried and replayed to provide intuitive and visualized decision analysis for event processing.

4)Virtual electronic fence

Set the electronic fence, monitor and count the position of the personnel, and send alarms to the personnel who enter the key area and or area.

5)Alarm management

Alarm records include alarm type, alarm location, alarm object, alarm time, and alarm status. You can search and query by time or alarm object. Alarm types include unattended alarm, one-touch SOS alarm, time-out alarm, wristband break alarm, heart rate alarm, and low battery alarm.

6)Unattended alarm

When the prisoner is alone in the inquiry, interrogation room, the alarm mechanism is triggered, the platform pops up the alarm information and voice broadcast prompt, and the monitoring video of the room where the alarm is triggered is popped up. If the alarm is triggered again in another room, it will be updated to the latest triggered monitoring screen.

7)Wristband breakage alarm

The alarm will be triggered when the wristband is cut after the inmate's anti-tampering bracelet is damaged, and the platform will pop up the alert box and accompany with voice announcement prompts.

8)Heart rate alarm

When the prisoner's heart rate is lower than 50 times/minute (can be set), the heart rate alarm will be triggered and accompanied by voice announcement prompts.

9)Case records can be tracked

The case record includes the information of the personnel handling the case, the name of the case and the time of the case, the place of the case, and can make fuzzy inquiries according to the personnel name,ID number,police number, etc.Significant benefits - Security supervision and control

Through the introduction of Woxu personnel positioning system, a public security case center in Anhui Province has turned passive processing into active supervision, effectively reducing the risk of supervision and law enforcement and realizing "intelligent all-round supervision" in the case area. At the same time, it plays a pivotal role in "increasing efficiency and reducing burden" by adopting the synergy of "human prevention + technology prevention", releasing a certain amount of safety supervision manpower and significantly improving the efficiency of safety supervision.
