Calibration platform monitoring system based on wireless video transmission
In order to improve the reusability of the metering module and the openness of the calibration platform, the integrated calibration platform adopts a unified network interface based on Ethernet to replace the traditional serial communication. In the process of calibration, it is necessary to establish a monitoring system to ensure that field operators carry out calibration work in a standardized manner. The paper puts forward the realization scheme of wireless digital monitoring system with digital signal processor and radio frequency transceiver chip as the core。The paper adopts H. 264 standard to encode video data. Experimental results show that under the premise of ensuring video clarity is not affected, the compression ratio is above 1:20, and the wireless module can achieve two-way communication within 300 meters.
