At present, public security, fire protection, industry and commerce, municipal administration, urban management, etc. have been equipped with many mobile command vehicles/law enforcement vehicles, which have improved the work efficiency of various departments and facilitated the collaborative work between departments. They have played an important role in major events such as the Olympic Games. Important role. As the requirements of all walks of life on city management, administrative law enforcement, etc. continue to increase, more and more mobile command vehicles will be put into use. Mobile command is an important development trend; however, most of the existing mobile command vehicles only solve the problem. For on-site evidence collection and other issues, a series of issues need to be resolved in order to realize true mobile command.
For example: (1) At the mobile command site, it is necessary to determine the main mobile command vehicle, and achieve coordination and interaction with other command vehicles and law enforcement vehicles (purpose: improve work efficiency, reduce mobile command costs, and exert the power of “mobile command” );
(2) Coordination and interaction with the existing command center (purpose: to make the mobile command vehicle a “mobile command center”, so that the existing command center can penetrate into the “front line”);
(3) Realize the real-time and effective call of various existing resources on the mobile command vehicle (purpose: improve the utilization rate of existing resources and reduce the cost of law enforcement). To solve the above problems, it is necessary to break through the following key links: (1) Build stable, reliable, and low-cost wireless communication between the mobile command vehicle and other command vehicles/law enforcement vehicles, existing command centers, and various existing resources. Link, realize the application of existing image information and other resources to the mobile command vehicle, expand the application field and scope of existing resources, and enable existing resources to realize “ubiquitous” mobile applications; (2) Flexible and convenient construction , A comprehensive mobile command platform with movable (dynamic) command, unified management, and real-time synchronization.
2. The system constitutes the overall structure of the mobile command management solution as follows:
Resource access terminal, mobile command terminal, mobile application terminal, terminal terminal
The entire system consists of “one platform, five terminals”:
One platform: mobile command management platform
The mobile command management platform is the core of the entire system. On the one hand, it integrates, dispatches, and manages various connected resources (including images that may be uploaded by the mobile command vehicle, etc.), and provides them to users who need to use it; on the other hand, it Various users are also managed in various aspects such as wireless link distribution, load balancing, access control, resource allocation and invocation, so that the entire system can run smoothly.The platform consists of five departments: Command vehicle
Law enforcement vehicle management, mobile command center management, existing resource management, mobile access resource management, system management, as shown in the following figure:
Mainly used by law enforcement vehicles, command vehicles and other larger mobile devices. Through this terminal, a stable and reliable wireless connection can be established with the mobile command management platform, and related resources within the scope of authority can be called, such as image information, grid information, etc. At the same time, it can accept the instructions of the command center and the main command vehicle, and become the executor of the mobile command “first line” or part of the temporary mobile command group
Type terminal: terminal for PDAPC resource access
The core part of the entire system adopts mature, stable and reliable technologies and products with completely independent intellectual property rights (for example, wireless communication adopts Datang’s SCDMA technology and products, and the underlying data collection adopts Lingyu’s WSN technology, resource integration And sharing, data transmission adopts Lingyu’s own coding and decoding technology, etc.)
The use of PDAs and resource-accessible terminals enables PDAs to be included in the mobile command and management system. On the one hand, PDAs can also share and use related resources (such as image information). On the other hand, they can also use PDA’s outstanding “single-soldier combat”. Ability to expand the coverage and depth of the mobile command and management system. Terminals: for PC (including desktop and laptop computers). It can be connected to the mobile command and management system through the existing wired government network or wirelessly. ；
The core part of the entire system of type terminals and PCs (1) adopts mature, stable and reliable technologies and products with completely independent intellectual property rights (for example: wireless communication adopts Datang’s SCDMA technology and products, and the underlying data collection adopts Times Ling Yu’s WSN technology, resource integration and sharing, data transmission adopts Lingyu’s independent coding and decoding technology, etc.);
Flexible networking, safe and reliable wireless transmission, intelligently adjustable terminal access and working modes;
A new SOA-based application system with powerful function expansion and application expansion capabilities;
Mainly for users in three areas:
(1) Users who need to temporarily access the mobile command management system and provide related resources;
(2) Users who are inconvenient to access and provide resources through wired means;
(3) Users who need wireless access for other reasons.In most cases, users who use this terminal are just resource providers. Under special circumstances, they can also apply for permissions such as mobile application type and mobile command type, and use the mobile command management system.
Features of Mobile Command Terminal PDA System
Five types of terminals: mobile application terminal, mobile command terminal, PDA
Mobile application terminal
It is mainly used by mobile command vehicles and other mobile devices with mobile command sites or spaces. In addition to all the functions of mobile application terminals, it also has the function of incorporating local resources into the mobile command management system. It has higher authority and can be nearby. Or remote command-related resources, making the mobile command vehicle a “mobile command center” with the function of a command center
