The invention discloses a fresh water conveying, monitoring and metering system for a water supply tugboat and a control method of the fresh water conveying, monitoring and metering system. The system comprises a PLC monitoring unit, an industrial personal computer, a printer, a Mimic monitoring board, an electric adjusting butterfly valve, an electric switch butterfly valve, a fresh water tank liquid level sensor, a water outlet flow meter, a water outlet main pipe pressure sensor and a water supply pump. The industrial personal computer or the Mimic monitoring board is combined with the PLC monitoring unit, and the PLC monitoring unit automatically or manually controls external water supply or internal water injection; the PLC monitoring unit obtains the liquid level and the tank capacity during still water according to the actually measured liquid level data set of the fresh water tank and controls the opening degree of the electric adjusting butterfly valve and the opening and closing of the electric switch butterfly valve, so that the liquid level and the liquid level difference of the fresh water tank are kept within the allowable range when water is supplied to the outside or water is injected to the inside. The functions of liquid level data self-perfection, abnormal condition alarm and report printing are achieved. When fresh water is injected or water is supplied to the outside, it is guaranteed that the stability of the tugboat is not affected by fresh water injection or output.
本发明公开了一种供水拖船淡水输送监控计量系统及其控制方法,该系统包括PLC监控单元、工控机、打印机、Mimic监控板、电动调节蝶阀、电动开关蝶阀、淡水舱液位传感器、出水流量计、出水总管压力传感器、供水泵。工控机或Mimic监控板与PLC监控单元结合,PLC监控单元自动或手动控制对外供水或对内注水;PLC监控单元根据实测的淡水舱液位数据集获得静水时液位及舱容,并控制电动调节蝶阀开度、电动开关蝶阀开关,以实现对外供水或对内注水时使淡水舱的液位和液位差保持在允许范围内,并具有液位数据自我完善、异常情况报警和报表打印功能。本发明实现在淡水加注或对外供水时,保证淡水注入或输出不会影响拖船自身的平稳性。
