eWSN Intelligent Police Management and Control System

System background

In 2016, the Shandong Provincial Public Security Department requested the Provincial Party Committee and Provincial Government to issue the "Opinions on the Construction of an Innovative Three-dimensional Social Public Security Prevention and Control System" and the "Three-year Plan for the Construction of a Three-dimensional Social Public Security Prevention and Control System in China", which clearly defined the The direction and goal of the construction of a “integrated” three-dimensional social security prevention and control system. Provincial public security organs at all levels base their efforts on the "three-dimensional and integrated" layout, and make every effort to meticulously build a social security prevention and control network.

The Legal Affairs Office of the Beijing Municipal People's Government issued the “Beijing Regulations on the Management of Non-Motor Vehicles (Draft)” on July 28, 2017, and sought opinions from the public. The "(Draft)" clearly states that illegal violations such as "exceeding standards" on the road and "fake cards and false certificates" will be regulated through legislative channels. At the same time, it is clear that electric bicycles, motorized wheelchairs for the disabled, and other non-motorized vehicles required by the municipal government must be registered and licensed before they can be driven on the road.

In order to strengthen city management, strengthen the management and control of electric bicycles, actively respond to the Ministry of Public Security's plan for the construction of a three-dimensional social security system for public security, and earnestly study and explore through the accumulation of experience in “strong police with science and technology” and the combination of “new thinking on the Internet” Solutions to the construction of a three-dimensional security system for social order in the new situation. Huawang Intelligence has developed an electric bicycle security system-"eWSN Intelligent Police Management and Control System-Car Guardian" based on the Internet of Things technology, "Safe City", and "Skynet Project", based on the actual situation of society through more than a year of study and research. "And plan to use this as an opportunity to extend and expand the three-dimensional social security system of community police, including police patrols in the community, management systems for official vehicles, intelligent security of hazardous chemicals, and intelligent protection of the elderly and children with intellectual disabilities.

System introduction

The "eWSN intelligent police management and control system" is mainly composed of a cloud platform, a multifunctional base station, an intelligent terminal, and an operation platform.

1) 1.1 platform architecture design

The "eWSN intelligent police management and control system" electric bicycle terminal uploads data packets through the WSN covering the whole city, and the data is processed by 808Server and stored in MongoDB. Business applications complete business functions by calling WebServer, and create Web Api for Web and APP transfer. The database server of this system supports rapid query and retrieval of massive data. The read and write performance is quite high, which meets the needs of users based on mass data query. The gateway server architecture handles high concurrency performance. This system is suitable for large-scale concurrent query, and supports the requirement that massive devices are online at the same time.

2) 1.2 Main Functions and Features of Big Data Cloud Platform

The main function of the China Cloud Intelligent Cloud Platform is to run a business processing system. The system mainly implements the following functions: hierarchical management of user information, license management, electronic maps and tracks, alarm and loss management, etc.

1.2.1 Main functions

用户信息分级管理 Hierarchical management of user information

The authority management of the public security platform facilitates police operations and improves user information security. It also provides detailed statistical analysis and GIS map access for the Municipal Bureau platform.

牌照管理 License Management

The system electronically registers the electric bicycle registration form, fully satisfying the information needed for electric bicycle vehicle management. At the same time, the system supports automatic matching of entries by reading the second-generation ID card information, and can scan documents and import camera snapshot information for registration, reducing the workload of central duty personnel data entry.

By entering the license plate information, driver information, mobile phone number, home address, vehicle information, and smart terminal card number information, it completed the summary of electric bicycle information in the jurisdiction, and provided massive information support for the effective management of electric bicycles in the later period.

电子地图和轨迹 Electronic map and track

When the vehicle out of the fence alarm occurs, the system automatically informs the vehicle's reserved mobile phone number through APP push or SMS. At the same time, after the electric bicycle user logs in to the system's cloud platform or mobile phone APP, the alarm location can be displayed on the electronic map in real time and the vehicle can be viewed. Driving track, vehicle history track. And through the one-button alarm function, the alarm vehicle can be sent to the police in the jurisdiction of the cloud platform. After the police confirm the alarm through the phone, by calling on-site video on the electronic map, the police can quickly understand the police situation and quickly lock the vehicle position. In some cases, by commanding the patrol card, the police can quickly retrieve the alarm vehicle, which greatly saves police resources and improves police effectiveness.

报警和挂失管理 Alarm and Loss Management

First report the loss through the APP or the computer's cloud platform, and confirm the alarm information by phone within half an hour. When the electric self-driving vehicle is successfully reported, the lost vehicle passes through the road junction and the community will immediately communicate with the multi-function base station. The police in the area will immediately receive the alarm information of the electric self-driving vehicle pushed by the cloud platform and quickly lock the vehicle position.

车牌与智能终端匹配管理系统 License plate and intelligent terminal matching management system

When a police officer is on duty, if a suspicious vehicle is found, the electric bicycle is scanned by the police handheld terminal, and the ID number obtained by the multifunctional base station is compared with the license plate information generated by the system. If it does not match the registration information of the electric bicycle, it is a suspect vehicle.

1.2.2 Main Features

云平台系统支持的基站容量可达5000个,人员、车辆容量可达300万人,可满足未来对电动自行车辆以外的其它重点人员、危化品、贵重物品的管控拓展,提高平台的综合效益。 ◆ The cloud platform system supports up to 5,000 base stations with a capacity of 3 million people and vehicles, which can meet the future control and expansion of other key personnel, hazardous chemicals, and valuables other than electric self-driving vehicles, and improve the platform's integration. benefit. In addition, the platform supports the access of the narrowband Internet of Things NB-IOT, which can realize the real-time positioning and supervision of key personnel and valuable materials such as business vehicles, network-reserved vehicles, and special groups (demented elderly, children, and control personnel).

Third, extended applications

Through the construction of the eWSN intelligent police management and control system, the sensing base stations form an "Internet of Things Perception Network" within the urban area. With this network, as long as the intelligent terminal is given to the object to be managed, the location, identity, and status of the entire city can be managed, and various intelligent management applications have emerged as the times require. Most cities regard the IoT electric vehicle management system as one of the entrances to the construction of smart cities. While solving local people's livelihood issues, they will also deploy and implement IoT platforms to lay the foundation for future expansion and extension of smart city applications.
