Problems solved by technology

In the above detection system, the flow detection server with GPRS receiving device adopts GPRS transmission mode, which is limited by the actual bandwidth of GPRS (only about 50kbps). When there are more than 10 collection sites, some intersection detection equipment and flow detection often If the server connection is interrupted, the monitoring effectiveness of the site and the real-time performance of data transmission cannot be guaranteed
