A multi-liquid level detection system capable of automatic networking and an automatic networking detection method

Abstract

The application discloses a multi-liquid level detection system capable of automatic networking and an automatic networking detection method. The system comprises a plurality of liquid level sensing modules connected in series through a wire harness. Each module comprises a liquid level detection unit, a communication unit and a processing unit. The communication unit has a signal receiving end and a signal sending end. The processing unit can update its bit number according to the bit number information in the upstream data frame, write the liquid level detection result into the corresponding bit of the data frame, and then forward the updated data frame. If no valid upstream data is received within a preset time period, the bit number of the processing unit is reset. The system can automatically complete the numbering, networking and state summary transmission of multiple liquid levels, and does not need to separately debug and identify schemes for different liquid level numbers, thereby effectively reducing the controller adaptation difficulty and reducing the deployment workload of multi-liquid level detection.
