Five. The System function
1. Temperature collection function.
Through the wireless temperature measuring terminal and the installation of continuous measuring temperature on the cable and cable joint, the bus, the contact,
The running state of cable and cable head is monitored in real time, and the measurement results are uploaded to the monitoring center database via communication network.
The server, through software analysis, can predict the early overheating of the equipment in advance, and realize the early prediction of failure and prevent the disease from occurring.
The function of early warning.
2. Communication function
The data set processor can communicate with the monitoring center through the power grid, or through the GPRS channel.
With the monitoring center, GPRS is provided by professional operators to ensure reliable communication.
3. Data processing function.
The monitoring center receives the individual monitoring-station of field data, through the analysis processing, preservation in the database, and with a wiring diagram, curve and table method is presented to monitor personnel, equipment and automatically detect the presence of thermal or overtemperature, on the basis of intelligent judgment without exception equipment, when there is abnormal situation, automatic with language, sound and light alarm. It is necessary to prevent in advance and ensure the safe and reliable operation of substation equipment.
4. Alarm function
When there is a temperature increase and more than setting the alarm limit, the system will send out alarm in different ways, including network alarm client, SMS, etc., and display the location of the emergency alarm and record the alarm time, timely and accurate guide maintenance and troubleshooting.
Network client alarm module in the received data processing center to send the alarm information, alarm popup Windows on the screen of the client immediately, voice alarm, alarm, screen flashing alarm, including the alarm information, prompt the user to immediately deal with the alarm information. SMS alarm platform to receive the data processing center alarm information, set the alarm plan in advance according to the user, according to the different type of alarm, the alarm device to send staff related to different alarm messages.
5. Browsing function
B/S structure of the monitoring center using the latest design, as long as you have appropriate permissions, on any computer on the LAN access to the data in the database, view real-time temperature and historical data of the monitoring, convenient to browse and manage.
6. User management.
The system has user management function, which can be added or deleted by the system administrator, management authority setting, etc., to ensure the safe operation of the system.
7. Data query function.
The system can query the alarm parameters, alarm recording, sorting and printing of each monitoring point. Check the monitoring parameters, historical data, sorting and printing of each monitoring point; According to the time query, according to the time period query, according to the monitoring station inquiry, according to the alarm query, provides a variety of conditions to inquire.
8. Perfect logging function.
The system can record the user's usage and alarm information. All warning messages can be queried by logging.
