The compressed air station monitoring system further comprises a monitoring room 9, and the controller 5 and the touch screen 6 are respectively arranged in the monitoring room 9. The controller 5 is a programmable controller such as S7-200 SMART PLC of Siemens and the touch screen 6 is a Wilton HMI.
In this example, the remote IO module 7 is connected to the controller 5 through a PROFINET bus 8, the controller 5 has a first PROFINET interface circuit, the remote IO module 7 has a second PROFINET interface circuit, and the first PROFINET interface circuit is connected to the second PROFINET interface circuit through the PROFINET bus 8. In other embodiments, the remote IO module 7 may also be connected to the controller 5 via a wireless network. The wiring is simple, and the maintenance is convenient.
In this embodiment, the pressure gauges 4 are electric contact pressure gauges for detecting the gas pressure in the gas supply pipeline 3, each pressure gauge 4 is respectively preset with an upper pressure limit value and a lower pressure limit value, the touch screen 6 is provided with an upper pressure limit alarm indicator lamp, a normal operation state indicator lamp and a lower pressure limit alarm indicator lamp, and each pressure gauge 4 is respectively corresponding to the upper pressure limit alarm indicator lamp, the normal operation state indicator lamp and the lower pressure limit alarm indicator lamp.
When the compressed air station monitoring system operates, the remote IO module 7 collects signals of each pressure gauge 4, the collected signals are transmitted to the controller 5 and processed by the controller 5, and the processed signals are fed back to the touch screen 6 to be displayed. The remote IO module 7 further collects signals of each frequency converter 10, the signals of the frequency converters 10 include operation signals, fault signals and the like, and the signals are transmitted to the controller 5, processed by the controller 5 and then fed back to the touch screen 6. The controller 5 also performs remote control operation on the first air compressor 1 and the second air compressor 2 according to signals of the pressure gauges 4.
Specifically, taking one of the pressure gauges 4 as an example, when the first air compressor 1 operates, the pressure gauge 4 detects that the pressure in the air supply pipeline 3 reaches a lower limit, a movable contact of the electric contact pressure gauge is connected with the lower limit contact, a signal is transmitted to the controller 5 through the remote IO module 7 to be processed, the controller 5 feeds a control signal back to the frequency converter 10 of the first air compressor 1 through the remote IO module 7 to continue to operate, and simultaneously feeds the control signal back to the frequency converter 10 of the second air compressor 2 through the remote IO module 7, so that the second air compressor 2 operates and supplies air together until the pressure in the air supply pipeline 3 is in a normal range, in the process, the controller 5 also transmits the signal to the touch screen 6, a signal lamp on the touch screen 6 is turned on by a starting pressure lower limit alarm indicator lamp, and a normal operation status indicator lamp is turned on.
