Digital City Management Audio/Video Command & Dispatch System

1. Industry Background
With the rapid development of the urban economy, city scale and population continue to expand, and the workload of law enforcement management has also increased rapidly, bringing challenges to the law enforcement management of the Urban Management Bureau. Among them, the monitoring, command, and dispatch of law enforcement vehicles in various jurisdictions are particularly prominent, mainly reflected in the following aspects:

1. The distribution and rapid response capability of vehicles within the jurisdiction;
2. The distribution of management targets (government, enterprises, public institutions, mobile vendors, etc.) within each jurisdiction is increasingly complex;
3. The workflow of complaint → determining the enforcement location → dispatching vehicles for enforcement → feedback on enforcement status → ... is becoming increasingly complex;
4. Waste of resources such as private use of law enforcement vehicles;
5. Disputes between the enforced party and the enforcing party, difficulty in on-site evidence collection, and an increase in petition (appeal) cases.
   To this end, in order to reduce costs, improve service levels and enforcement efficiency, strengthen the management and dispatch of law enforcement vehicles, and emphasize cooperation, coordination, and information sharing among law enforcement vehicles, Beijing Raytrans Digital Technology Co., Ltd. has launched the Digital City Management Audio/Video Command & Dispatch System, integrating GPS technology, trunked communication technology, audio/video multimedia command & dispatch, 3D GIS technology, and industry-leading ICT (Information and Communication) technology and various communication means, while drawing on advanced management experience of personnel and vehicles in related industries to build an urban management law enforcement command & dispatch system.
   2. Raytrans Solution
   The Beijing Raytrans Digital City Management Audio/Video Command & Dispatch System consists of multiple modules including the command & dispatch center, command & dispatch terminal equipment, GIS/GPS/GPRS system platform, vehicle-mounted terminals, and wireless trunked intercom.
   The solution topology is as follows:

**2.1 Solution Features
** 1) The command & dispatch communication center is the core of the entire business system, responsible for providing processing and switching for the entire audio/video command & dispatch system. Professional audio/video dispatch functions can mobilize the entire ICT business. The system integrates multiple transmission paths and can communicate with terminal vehicles through fiber, E1, MAN, GPRS/CDMA, WIFI, and other means, and can achieve seamless integration with wireless trunked intercom systems, organically integrating wired and wireless systems. It enables real-time on-site image upload, voice intercom, vehicle positioning, video conferencing, and wired/wireless intercom systems for terminal vehicles;
2) The mobile patrol vehicle interacts with the command & dispatch center to complete classification, recording, and forwarding of various information, while monitoring and managing the overall network status. Combined with GIS and mobile terminals, it enables monitoring and intelligent dispatch of personnel and vehicles, achieving optimized allocation, dispatch, and management of mobile resources, and improving dispatch efficiency. Vehicles can also provide long-distance relay mode via wireless bridge, allowing multiple vehicle-mounted devices or handheld devices to share broadband Ethernet services.
3) The central command hall provides large-screen integrated information display, various information recording, storage, and processing servers, various emergency response plans, responds to and handles emergency events, and provides processing measures such as tracking and positioning, monitoring and recording, video capture, scene upload, and remote control.
4) The GPS vehicle positioning and monitoring system is used to locate and monitor patrol vehicles equipped with GPS vehicle-mounted terminals, and is an important means for the urban management information center to achieve spatial visual management of patrol vehicles;
5) Patrol vehicles can be equipped with panoramic scanners to scan changing scenes and send the changed images to the GIS system for updated display via GPS/GPRS/WIFI and other transmission paths.
6) Supervisory information officers are each equipped with a "City Management Mobile Terminal" (ChengGuanTong), which enables collection and reporting management functions through supervisory data wireless collection devices, while receiving verification and inspection tasks assigned by the supervision center. The ChengGuanTong system mainly implements information collection, transmission, and feedback functions. Supervisors conduct regular patrols within their assigned management grids. If urban management issues are found, they use mobile video terminals for on-site recording and send the discovered issues from the information collection terminal to the information supervision center via the GPRS wireless network.
7) The GIS supervision and command subsystem is a GIS platform for real-time information monitoring and 3D visual display, provided to leaders at all levels and business personnel for supervision and command. It enables communication with law enforcement vehicles and task assignment through clicking and selecting vehicle information displayed on the GIS. It implements various operations on the 3D GIS map of the city, including zoom in, zoom out, pan, distance measurement, object selection, full map display, printing, etc., meeting the needs of municipal management supervision and command based on electronic maps; it can perform real-time positioning and display the geographic locations of vehicles and supervisors.
