Hand held terminals can be used for vibration monitoring in traffic systems

At present, the global earthquakes are frequent, and the operational safety of high-speed railways has also been seriously threatened. Therefore, it is extremely urgent to construct a high-speed railway seismic monitoring system technical solution that meets the needs of the current situation and can be implemented. As a manufacturer of self-developed equipment for hand held terminals, Beijing Speedata Technology has been specializing in the field of seismic applications for many years, and through the application of industrial PDAs, it has brought solutions for this application.


Use scenario: The Seismic Railway Seismic Solution installs a seismic module on and around the high-speed rail. The seismic module uses real-time seismic intensity wave monitoring to achieve early warning of the earthquake, and through the hand held terminal RFID hand held USB to CAN port Connected to the terminal of the Institute of Iron and Steel, the seismic module transmits the detected wave value to the hand held terminal RFID handset, and converts it into a digital signal for threshold judgment. When the alarm threshold is exceeded, a dry contact alarm signal is generated and sent to Monitoring unit. At the same time, the strong vibration recorder integrates the seismic wave data and the alarm signal and transmits it to the data processing equipment through the seismic monitoring unit to provide data reference for the start up of the emergency plan after the disaster. If the data exceeds the alarm threshold, the device will send an alarm and transmit the warning to the moving train through the set IP network to stop the train that is driving at high speed. If the situation is urgent, it will send control information to the traction power supply system to stop the power supply. Brake immediately.


Advantages of the application of the RFID terminal of the hand held terminal: 1. Real-time strong, can control the train braking at the first time of monitoring the earthquake; 2. High alarm accuracy; 3. Direct control, less transmission, reliability high.
