1.1 Analysis of the current status of in-vehicle information products
Although the number of police patrol cars equipped with information technology has gradually increased in recent years, there are still many shortcomings：
l Device functionality duplication
Police patrol cars and police officers are equipped with law enforcement recorders, walkie-talkie, police communications and other related information equipment，But the equipment functions have overlap， For example, many devices have positioning functions，However, due to different accuracy and corresponding platforms, the positioning of each device is biased，And it is impossible to achieve unified scheduling management；
l Low efficiency of command and dispatch
A large number of front-line departments still use traditional walkie-talkie to dispatch police forces，No efficient and unified command and dispatch platform，
It is difficult to link police force, law enforcement videos, police situations, duties and other information，this results in low efficiency in receiving and handling police calls;
l Incomplete information collection
Although police patrol cars and police officers are equipped with law enforcement recorders or a small amount of on-board monitoring, the camera angles are limited and the surrounding situation cannot be fully seen. In the event of an emergency, the situation at the scene of the incident cannot be fully restored；
l The business process is cumbersome
After police officers enforce the law at the scene, they need to record the case, return to the station, and then enter the case into the system. The overall operation is cumbersome and increases the police workload;
l Evidence collection methods are limited
For traffic violations, fixed capture equipment and manual on-site evidence collection are still the main methods at present. However, fixed equipment has a large number of monitoring blind spots, and manual evidence collection is not only time-consuming and labor-intensive, but also inefficient.
1.2 Project implementation purpose
Taking unified planning and high-tech information equipment as the starting point, we will build a road patrol and law enforcement team with fast response speed, high degree of informatization , and strong law enforcement capabilities.
l Improve police efficiency
Integrate existing multiple platform resources to create a police mobile comprehensive combat platform to form a unified collection, unified processing and unified utilization of data.By simplifying business processes and improving management efficiency, we can achieve collaborative operations among police resources, improve rapid response capabilities, and dispatch police in a timely manner to avoid the expansion of small disputes and the escalation of accidents.
l Integrate prevention and control
Integrate and upgrade functions of existing vehicle-mounted equipment.Enhance the role of law enforcement in daily patrols through customized analysis methods such as human and vehicle feature recognition and information comparison.Combined with effective handling plans, the police situation can be analyzed and judged, and abnormal behaviors can be prevented and intervened in advance.Through the integrated platform, we can timely grasp the dynamic distribution of personnel, vehicles, and equipment, respond promptly to emergencies, quickly control, reduce impacts, reduce losses, and achieve “integration of prevention and control.”
l Improve the efficiency of law enforcement and evidence collection
By installing a high-precision, intelligent, and user-friendly vehicle-mounted evidence collection system on police patrol vehicles, dynamic supervision and intelligent evidence collection of vehicles on the road can be achieved.It plays a positive role in curbing traffic violations, standardizing road traffic order, reducing accident rates, creating a safe and smooth traffic environment, and saving a large number of police personnel for other work.
1.3 design principles
l principle of advancement
The system must be advanced, forward-looking, and scalable in terms of design ideas, system architecture, adopted technologies, and selected platforms. On the basis of meeting existing needs, the system must be able to adapt to the growth and changes in demand within a certain period of time in the future. Guarantee return on investment in equipment.
l Practicality Principle
The equipment configuration will be based on meeting current needs. While saving investment, the needs of highway management will be fully considered to determine the system scale, so that it can adapt to future highly integrated and systematic management requirements to meet future business volume growth needs.
l Integration principle
The construction of the entire system must fully reflect the integrated construction of the police command system and follow the construction principles of system integration such as unified process specifications, unified technical standards, unified data structures, and unified operating platforms.
l reliability principle
Scientific design, people-oriented, ensures the reliability of system equipment operating under various natural environmental conditions.
l security principles
In order to effectively ensure the safe and stable operation of the entire wireless network communication system, the network should be able to provide network layer security means to prevent illegal intrusion by external members of the system and overstepping operations by operators, and protect the safe operation of the wireless network.
l Standardization principle
System design should comply with international standards, national standards, and mainstream industry standards.
l The principle of easy control
In order to reduce the labor intensity of police officers, the system should be simple to operate and easy to learn and use.
l Ease of maintenance principle
The management and maintenance functions of the system can be customized and modified flexibly and conveniently according to actual conditions in various places.
