Abstract:For the laboratory design of high spatial resolution and low price liquid leakage sensor, in order to achieve remote communication, on the basis of the original sensing system, added MQTT protocol for remote push and interaction of data, at the same time based on the cross-platform characteristics of Qt to develop monitoring software that can be used on both PC and mobile terminals, the system administrator can send control instructions to the liquid leakage sensing system through the PC side, remote control and real-time monitoring of the liquid leakage site, System repairers can view maintenance notices and alarm information through the mobile terminal, and submit maintenance orders after the repair is completed. The system realizes the real-time collection and remote monitoring of the liquid leakage monitoring system, and has a good application prospect.
