[0031] Among them, as Figures 2 - 4 shown, the support includes a lower clamping block 201 and an upper clamping block 202. The lower clamping block 201 is fixedly installed on the top of the pneumatic valve 1. Installation grooves for cooperating with the outer shape of the proximity sensor 2 are respectively formed on the clamping surfaces of the lower clamping block 201 and the upper clamping block 202. The proximity sensor 2 is fitted and clamped inside the upper and lower two installation grooves, and the lower clamping block 201 and the upper clamping block 202 are connected and fixed by a first compression bolt 203. The proximity sensor 2 is installed and fixed by the lower clamping block 201, the upper clamping block 202 and the first compression bolt 203, which is convenient for the maintenance and replacement of the proximity sensor 2, convenient for disassembly and installation and fixation. A rubber pad can be arranged inside the installation groove to facilitate the stability of the lower clamping block 201 and the upper clamping block 202 for clamping the proximity sensor 2 and avoid loosening.

[0032] Among them, as Figure 3 shown, the detection plate 3 is fixedly installed on the transmission rod 101 by screws 301. The detection plate 3 is fixed by the screws 301, which is convenient for the maintenance and replacement of the detection plate 3 and convenient for disassembly and installation.

[0033] Among them, as Figure 5 、 Figure 6 shown, when the pneumatic valve 1 is in the closed state, the side surface of the detection plate 3 and the sensing end surface of the proximity sensor 2 form a 90° angle. When the pneumatic valve 1 is in the open state, the side surface of the detection plate 3 is close to and parallel to the sensing end surface of the proximity sensor 2. By using the transmission rod 101 of the pneumatic valve 1 to drive the detection plate 3 to approach the proximity sensor 2 for detection, the real-time monitoring and feedback of the pneumatic valve 1 switch are realized.

[0034] Among them, the model of the proximity sensor 2 is LJ12A3-4-Z / BX, which has high measurement accuracy and good use stability.

[0035] Among them, the controller 5 is a PLC, and its model is 6ES72350KD220XA8. The controller 5 can receive the signals sent by the proximity sensor 2, perform signal amplification, filtering, conversion and other processing, and convert the original signals into recognizable digital signals or analog signals.

[0036] Among them, the communication module 4 is a 4G communication module or a 5G communication module with the model of DL7300. The 5G communication module can be a 5G communication module with the model of SIM8210C or SIM8210C-M2. It is a 5G communication module developed based on the Qualcomm 315 5G Internet of Things modem, supports 5G NR / LTE-FDD / LTE-TDD frequency bands, complies with the R15 protocol, and has a maximum rate of up to 1.5 Gbps. It supports GNSS function and FOTA function, and has rich network interfaces, including PCle, USB3.1, GPIO, etc. The communication module 4 transmits the processed signals to the central processing system 6 wirelessly to achieve real-time transmission and sharing of data.

[0037] Among them, the central processing system 6 is a computer. The central processing system 6 receives the status information from each valve, conducts data analysis and storage, judges the actual status of the valve according to the preset logic, and at the same time feeds back the valve status to the operation interface to achieve human-machine interaction.

[0038] Among them, as Figure 1 shown, a protective cover 7 is fixedly installed on the top of the pneumatic valve 1 through a second compression bolt 701. The protective cover 7 covers the periphery of the proximity sensor 2, the detection plate 3 and the transmission rod 101. The proximity sensor 2 is protected by the protective cover 7 to prevent the outside from approaching the proximity sensor 2, increasing the stability of the use of the proximity sensor 2. In addition, the protective cover 7 is installed and fixed by the second compression bolt 701, which is convenient for disassembly.

[0039] Among them, the controller 5 is electrically connected to the actuator of the pneumatic valve 1. The central processing system 6 can also feedback control instructions sent by the controller 5 according to production requirements to control the opening and closing state of the pneumatic valve 1, forming a closed-loop control.

[0040] As is well known to those skilled in the art, the working principles and wiring methods of the pneumatic valve 1, the proximity sensor 2, the communication module 4, the controller 5 and the central processing system 6 are common knowledge, and they all belong to conventional means or well-known common sense, so they will not be elaborated here.

[0041] Working principle: As Figure 7As shown, during use, when the pneumatic valve 1 is in the closed state, the side surface of the detection plate 3 forms a 90° angle with the sensing end surface of the proximity sensor 2. When the pneumatic valve 1 is in the open state, the side surface of the detection plate 3 is close to and parallel to the sensing end surface of the proximity sensor 2. By using the transmission rod 101 of the pneumatic valve 1 to drive the detection plate 3 close to the proximity sensor 2 for detection, real-time monitoring and feedback of the opening and closing of the pneumatic valve 1 are realized. The proximity sensor 2 transmits the signal to the controller 5. The controller 5 receives the signal sent by the proximity sensor 2 and performs signal amplification, filtering, conversion and other processes, converting the original signal into an identifiable digital signal or analog signal. Then, the processed signal is transmitted wirelessly to the central processing system 6 through the communication module 4, realizing real-time transmission and sharing of data. The central processing system 6 receives the status information of each valve, performs data analysis and storage, and judges the actual status of the valve according to the preset logic. At the same time, it feeds back the valve status to the operation interface to realize human-machine interaction.
