摘要
针对高寒、偏远、有毒、放射性、易燃易爆等条件下,依靠人工难以完成液位控制的问题,提出了多适应性远程无人液位控制系统设计。系统由上位机、下位机构成。下位机由STC89C52主控芯片、超声波液位监测和ULN2429A液面测量单元,液位自动控制模块、GPRS通讯模块等构成。液位测量模块对液位不断进行监测,同时将液位信息通过GPRS模块实时传送回上位机。当液位低于工作下限时,主控芯片控制液体自动控制模块回注液体。系统能够对导电和非导电多种性质的液体实现远程无人控制,具有一定的实用价值。
Aiming at the problems of artificial controlled liquid level in the cold, remote, toxic, radioactive, inflammable and explosive conditions, the design of multi-adaptive remote unmanned liquid level control system is proposed. The system is composed of upper and lower machine.The lower machine is composed of STC89C52 MCU,liquid level measurement unit with ultrasonic and liquid level measurement unit with ULN2429A,liquid level automatic control module, GPRS communication module and so on. The liquid level measurement module is used to monitor the liquid level and the liquid level information is transmitted back to the upper machine through the GPRS module. When the level is below the limit, the main control chip to control the liquid injection liquid automatic control module. The system can realize the remote control of the electric and non electric liquids, which has a certain practical value.
