High-precision positioning solution for personnel of a people's procuratorate in Jiangsu Province

Project Background

As an important legal supervision organ of the country, the procuratorate has been involved in case safety accidents from time to time. To ensure case safety and prevention, "Smart+" is becoming a new blue ocean in the construction of public prosecution and law.

A people's procuratorate in Jiangsu Province to strengthen security work, for the first time in the procuratorate building on the first floor area introduced "UWB high-precision positioning system". Through this system, it effectively solved the difficult problem of personnel security control, and realized the collaborative and efficient technology management in every aspect.

Project Demand Breakdown

Stereoscopic security defense line to help the Procuratorate more efficient and safer handling of cases

The project, a total of about 712 square meters of office area to achieve accurate positioning coverage, positioning areas include three interrogation rooms, an interrogation room, a bailiff duty room, an announcement room, a hearing room, a medical room, a detention room, two security channel exits; electronic fence focus on monitoring areas for interrogation room announcement room, lawyers negotiation room, security channel, elevator entrance and the main entrance.

In the actual scenario, the hardware system is mainly based on "UWB anti-demolition watch + anchor". After entering the area, the suspects are required to wear the UWB anti-tampering watch with positioning function in the first place, so as to facilitate the identity locking and high precision positioning of the personnel.

The prosecutor's office is a typical office scenario with many rooms and a small single area. 37 units are deployed in a single base station indoors, with a coverage radius of 30m, using a wired connection. An additional wireless time synchronization base station is added to make the positioning more accurate and data more secure.

At the software system level, the WPAS location business convergence platform is the main focus, mainly providing users with a series of visualization services based on location data. In the daily work, the bailiff on duty can view the personnel's location, historical trajectory and alarm of crossing the police line in real time through the background, and the information is presented clearly at a glance, which largely reduces the risk of supervision and enforcement and prevents accidents.

Woxu WPAS location business integration platform

Woxu real-time positioning system solution can also promote the upgrading of the infrastructure and control system of the procuratorate through video linkage, long time detention alarm, heart rate monitoring, historical trajectory storage and return visits, forming a three-dimensional security defense line of the regional perimeter, strengthening collaborative prevention, making safe custody and supervision without blind spots, and improving the overall security and efficiency level of the case work.

UWB intelligent solution

The Woxu team customizes the following UWB positioning technology solutions for the actual situation of the procuratorate.

Program Architecture

Positioning dimension

The positioning area "detention room" is zero-dimensional positioning, the aisle is one-dimensional positioning, and all other rooms are two-dimensional positioning.

Function Realization

Real-time positioning of personnel
After the personnel wear the uwb tag, they can view the location coordinates, name, time and access of the target positioned in real time through the management platform.

Electronic fence alarm
Early warning control of key areas and construction of the corresponding virtual electronic fence. The electronic fence can limit the access personnel and access time, and also set the access quantity, and give different types of alarms when the target gathering exceeds the above conditions.

Historical track inquiry
It can query the activity trajectory of personnel within one year, query and playback the trajectory of a single person or multiple people in a certain area, and provide intuitive and visualized decision analysis for event processing.

Project Value

Site picture

Woxu leads the positioning black technology to help promote the public prosecution and law "intelligent case handling".

In the context of digital reform, the construction of political and legal intelligence is actively promoted. As a leading solution provider of location services, Woxu is helping many courts and prisons to successfully realize the management upgrade of "smart justice" and "smart prison". The acceptance of the Procuratorate project is another brilliant addition to Woxu's public prosecution and law case project unit, and the feedback from customers on the actual application effect is also unanimous praise and recognition.

In the future, Woxu will further exert its technical research and development capability, project implementation capability and program advantages for public prosecution and law enforcement industry applications, through UWB and other positioning and technology integration programs, with business practice as the main core, to help political and legal construction to achieve security management refinement and daily duty wisdom.
