Requirements Overview
With the development of modern communication technology and test and measurement technology, the era of data transmission has come. The remote video monitoring system using microwave communication technology, digital video processing technology, CDMA/GPRS communication technology, IP communication technology and optical fiber communication technology and other advanced communication technologies can observe the operation status of coal mines in real time and provide intuitive image information for safe production. At the same time, it can improve the working environment of observation and measurement staff, reduce staff, and make it unattended and less on duty.
demand analysis
Coal mine video monitoring system can be mainly used in coal mine production monitoring:
I. Coal mine management 1. Through the video monitoring system, the work conditions of coal mines can be monitored.
2. When the staff is producing mines, they need to monitor the environmental changes of coal mines through video surveillance systems.
3. Under certain circumstances, such as the import and export of coal mines, most of the time is in an unattended state and surveillance cameras need to be set up to monitor in real time.
4. Monitor the surrounding environment of mines and mines.
Second, the mine monitoring 1, through a video surveillance system, can keep abreast of the situation around the mine well.
2. When the miners enter the mine, they need to monitor the entrance and exit of the mine through a video monitoring system.
3, monitoring the safety on the mine, timely clearing the hidden dangers of the mine, and ensuring the safe operation of the coal mine
According to the characteristics of the coal mine project and the coal industry, monitoring projects for coal mines, mines, and other important facilities often involve a wide geographic area, a large number of monitoring points, a relatively long distance and relatively dispersed monitoring points, and a large-scale monitoring project. The system stability requirement is very high, and it is necessary to minimize the maintenance of the equipment in the future.
According to the above characteristics, we have designed a remote video monitoring system for coal mines that is applied to the coal industry. According to the networking method, we can divide it into: front-end video capture, video communications, and central control. The system structure is shown in the figure:
two. System Overview The usual remote monitoring system is to place a monitoring computer at the remote site (site) to perform data acquisition and transfer it to the local computer through the Modem. This does not apply to occasions where there are no computers on the unattended site. Such as relay stations built in the mountains to monitor, widely distributed pumping unit monitoring, coal mine monitoring, well monitoring.
This system is suitable for applications that range from a few kilometers to thousands of kilometers. Etienne ET-8100 establishes a connection through an incoming text message call, that is, maintains a communication connection with the monitoring center. If the communication connection is lost, the monitoring device can quickly resume the connection and send the image again. Collect data from the remote controller. Real-time video is displayed through the receiving software on a computer connected to the Internet.
three. System function 1. Realize automatic connection.
2. Suitable for video surveillance applications ranging from a few kilometers to thousands of kilometers.
3. After the line is dialed, real-time data transmission is performed.
4. The video is stored remotely on the receiving end.
5. The acceptance software can be monitored and controlled in real time through the LAN.
four. System Implementation 1. Monitoring point configuration Connect video server and CCD camera
2. Configuration of monitoring center Install video receiving software and use web to set up the port. Run the receiving software.
3. Connection configuration Use any phone, send ga, ip to the SIM card number in the video server, and return a ga,***.***.***.*** to start the connection.
4. Startup configuration received a return message and a video will be displayed after a few seconds. The system starts.
