| 稳定水压供给设备是岩石力学水力耦合试验的关键装置,以高压气体为动力设计的水压施加装置具有压力稳定、能耗低的优点。本文以PC为上位机,西门子S7-1200为下位机设计了一种以高压气体为动力的压力控制系统。系统中PLC采集数据与上位机目标压力值实时交互,通过自动控制电磁阀开闭实现高压气体输入量的动态调控,待系统内水压接近设定目标值后,再由控制系统启动电动试压泵精准调压至设定目标值。 |

| The stable water pressure supply device is a key device for rock mechanics hydraulic coupling test,the water pressure application device designed with high pressure gas as power has the advantages of stable pressure and low energy consumption. In this paper, the pressure control system powered by high pressure gas is designed with PC as the upper computer and Siemens S7-1200 as the lower computer. In the system, PLC collects data and interacts with the target pressure value of the upper computer in real time, and realizes the dynamic adjustment of the input amount of high-pressure gas by automatically controlling the opening and closing of the solenoid valve, After the water pressure in the system is close to the set target value, the control system starts the electric pressure test pump to precisely adjust the pressure to the set target value. |
