I. Overview As an important transportation department of the country, its daily stable operation determines the normal operation of national production and life. In addition, the railway system departments are numerous, scattered, and the site environment is complex, which has become a major obstacle to daily maintenance. The implementation of remote remote viewing systems within the railway system will greatly resolve these contradictions. "Jiaante" remote remote viewing system adopts advanced technology. Operators and leaders of various departments can use the existing computer network and office microcomputer of the railway system to realize all monitoring sites or local crossings in the dispatching center or local locomotive section. And the monitoring of the environment along the railway, greatly reducing the workload of daily personnel inspections, facilitating the timely detection of dangerous hazards and ensuring safe production.
Second, the basic requirements and configuration
2.1 Basic requirements The wireless transmission is used to transmit the video signals of each monitoring point to the remote network. The purpose is to realize the security management of the entire station. The monitoring system can grasp the various conditions of the monitoring points at any time, and browse through the image of the monitoring points. And control and can realize video (audio) recording, playback, query, and provide services for relevant departments.
2.2 Equipment Configuration According to the needs of users, the equipment configuration is mainly composed of three parts, namely the monitoring center equipment in the station, the sub-control center equipment and the front-end monitoring point equipment.
The monitoring center equipment in the station includes: monitoring host (installation main control software), large screen projector (optional), client PC, client software.
Each sub-control center: client PC, client software.
Front-end monitoring point devices include: video server (JAT-S), high-speed dome (or: PTZ + PTZ decoder + camera), cabinet (for outdoor monitoring points, video server, PTZ decoding, power supply, etc.) Together).
Equipment installed outdoors must be selected for outdoor environments, including PTZ decoders and pan/tilt.
1. System structure The system consists of three main components:
1. Front-end monitoring point;
2. Monitoring Center;
3. Sub-control center;
3.1 Front-end monitoring point device connection as shown in the "scheme structure diagram".
The core device is the network video server Hikvision Rackmount Video Server, and the video signal of the camera is directly connected to the wireless device through the Hikvision Rack Video Server.
The model of the camera can be selected according to the location and function of the specific monitoring point. Consider the following configuration:
Each monitoring can select an ordinary camera, a camera with a pan/tilt or a high-speed dome color camera according to actual needs. This solution selects an outdoor integrated dome camera according to actual conditions.
Installation of monitoring points: For outdoor monitoring points, install video server and PTZ decoder in a dedicated cabinet to provide 220VAC power supply and RJ45 twisted pair interface.
3.2 Monitoring Center Server Monitoring Center Set up a server and install the main control software. The server manages all front-end JAT and front-end monitoring devices and maintains network connections with them. At the same time, it implements authorization management for users of monitoring stations in all networks. All users can connect to front-end cameras through any computer on the LAN. Permissions monitor, query, record playback, etc. the image.
After the main control software is installed, the system automatically configures the storage path of the recorded data. The user can use the management software of the server to modify the configuration as needed. The system supports distributed storage of recorded data, which provides a possibility for large-capacity storage.
A monitoring workstation can be set up in the monitoring center. The monitoring workstation acts as a system administrator user to manage devices and users in the system, including video data maintenance and management. The workstation can be connected to a projector for monitoring or system demonstration (optional).
3.3 On the client Internet computer, users only need to install the Jiaant client software. The system administrator can provide the legal identity and system usage rights of the login server, and it can become a monitoring workstation.
Monitoring software: Provide real-time monitoring of 4/9/12/16 screens, pan/tilt or dome control.
Query playback software: Query according to lens name, date/time, recording type, etc., and play back the query result.
The video signal of the front-end monitoring point camera is directly connected to the network through the video server, realizing a digital video transmission system in a true sense.
The monitoring center only needs one computer as the server (the server configures the corresponding number of hard disks according to the recording requirements), and can configure a monitoring workstation for system management and setting. When needed, a projector can be configured to connect with the workstation for normal operation. Surveillance.
