Distributed Command Center Solution

1. Project Overview

The command center is an all-weather and high-intensity organization that improves the government’s protection of public safety and handles public emergencies. It is the central organization for information processing, monitoring and control of the entire system. It makes judgments based on the current operating conditions and expected changes of various systems. , decision-making and command. The construction of the emergency command center not only requires real-time control of all audio and video information in the area under its jurisdiction, but also meets real-time business handling, data integration, meeting decision-making, emergency handling, on-site command, image processing, visual touch display, human-machine Interactive control and other requirements.

2. Functional requirements

1. Satisfy the operation management and adjustment functions of local audio and video signals.

2. Meet the needs of police monitoring and supervision under normal conditions and coordinated command and dispatch under emergency conditions.

3. Support public security, fire protection, first aid and other departments to integrate the imported data and display it on the display terminal, and can deeply correlate data from different sources, which is convenient for dispatchers to conduct overall analysis, and when safety hazards are discovered Can quickly issue emergency orders to various functional departments.

4. Establish an early warning mechanism for various focus police situations, automatically monitor the development trend of various focus police situations, give early warning to changes in various police situations, and link various emergency resources to conduct unified command and dispatch to achieve rapid emergencies. dispose of.

5. Support the collaborative management of agents, to meet the needs of users to manage multiple hosts with one operator, and the needs of multiple operators for multiple hosts. Major business can be managed collaboratively by multiple people and delivered to the big screen. Not only can it reduce energy consumption, save rack and computer room space, but also avoid the clutter caused by redundant keyboards, monitors and mice.

6. Support environment control, realize on/off control of conference equipment through wireless touch tablet or control computer, realize up and down, left and right rotation and movement of the camera, stretch and switch of the lens, switch the content of all display devices in the venue, and perform sound reinforcement equipment. Adjust the volume of the sound, open and close the curtains, adjust the light switch, etc. The visual operation interface can be customized according to the operation requirements. It supports simultaneous feedback and control of multiple tablets, completes rapid visual scheduling of large screen walls, and performs unified control of environment and monitoring equipment.

7. Expansion function, powerful expansion function, support expansion of individual combat system, super high score GIS, big data service platform, urban sky eye system, access control service system, recording and broadcasting service system, etc.

3. Scheme configuration

According to this series of needs, in the construction of the emergency command center project, we have equipped the command center with a Distributed System. Rishi distributed system adopts network IP technology to connect audio and video collection, transmission and display through digital network, unified control and management of geographically dispersed nodes, and easily integrate audio and video collection, transmission, control and display of command center. The displays are all connected through a digital network for centralized management and control.

The basic composition of this system is composed of high-definition input and output nodes, network switches, environment control hosts, recording and broadcasting service hosts, etc. The design is decentralized, and the failure of a single node will not affect the operation of other nodes. Operators can manage and control all equipment on the PC terminal or the touch terminal, and can retrieve the video images of the input nodes of each department. The specific functions are:

1. Preview the audio and video signals of all input nodes in real time, and manage and classify all audio and video sources according to permissions.

2. Support real-time input signal preview and echo to ensure that the status of each signal is under control; the size of all audio signals is adjusted.

3. All input and output boxes are equipped with USB interfaces, support KVM function, realize a set of keyboard and mouse to manage multiple target devices, realize the isolation of operation end and service host in physical space, ensure the security of device data, and at the same time can The operator performs permissions to ensure data security and achieve collaborative management.

4. Compatible with various operating systems, support shortcut keys, OSD menu and mouse direct cross-screen switching operations, support visual intercom between any seats, support file transfer, U disk copy storage and other operations.

5. Control the display system, control the switch on and off of the large screen, and open the window to roam and superimpose any image on the screen.

6. Environmental control, volume adjustment, lighting, curtain control, equipment power management, etc.

7. Monitor and control the indoor environment, monitor the indoor temperature and humidity, and then automatically control the ventilation or cooling of the air-conditioning panel.

8. Support one-key screen clearing, storage, and recall of display solutions.

9. Support audio two-way intercom, voice call between any nodes; support can directly decode various brands of IPC Camera.

10. Support high-quality lossless stereo balanced input, built-in audio input acquisition module to ensure that audio and video can be processed synchronously.

11. Support account password login, multi-level authority management, and operation log record.

12. Support POE power supply and external power supply dual power supply mode, which is convenient for on-site wiring selection; can be flexibly selected according to the on-site environment; using embedded hardware, the equipment is stable, safe and reliable, ensuring 7*24 long-term efficient and stable operation.

13. Support node loop-out function, which can display the input signal at the input end. The node supports system-wide multimedia video input preview and large-screen output echo, and supports synchronous operation of various terminals such as PC, PAD, and touch all-in-one.
