Considering the disorder of tank management at the well cleanout process, a ZigBee wireless network technology based tank liquid level monitoring and control system is designed using the advantage of ad hoc network. The tank liquid level monitoring and control system consists of the monitoring centerScomputer,Scommunication node,Scapacitive sensor for liquid-level measurement and dataSacquisition node. The main function of communication node is communication mode conversion between RS232 bus and ZigBee to realize monitoring centerScomputer to integrate into the ZigBee network. The main function of dataSacquisition node includes data acquisitionSof designed capacitive liquid sensor and ZigBeeSnetwork communication. STM32L is used as main controller and FZB5200 ZigBee module is used to realize ZigBee network connection. Through using theSdesigned monitoring and control system, the tank liquid level information can be achieved in real time, the present tank and the absent tank can be managed orderly, and eventually the efficiencySof well cleanout process is improved and process continuity is guaranteed.
