[0048] As an example, the intelligent control system board 14 is provided with a display processing module 141, a running processing module 142, an abnormal revision control module 143 and a logic storage module 144.

[0049] The display processing module 141 is used for extracting parameter information and running state information in the data packet, compiling the display data into a graphic text form in a specified format, and displaying on the liquid crystal display touch screen 13 to form a man-machine interface.

[0050] The running processing module 142 is used for parsing the data packet, judging whether the automatic running control instruction needs to be started according to the parsing result, and when the automatic running control instruction needs to be started, transmitting the instruction data packet in the form of a coded data packet in a specified format to the second wireless transceiver component 12, and the second wireless transceiver component 12 modulates the data packet into a wireless carrier signal and sends it to the movable wireless switch group 2 through the second invisible antenna 11 to control the running state of the movable wireless switch group 2.

[0053] The above describes the specific system architecture of the application in detail, and based on the above system architecture, the specific control process of the handheld wireless controller 1 and the movable wireless switch group 2 of the system is as follows:

[0054] The handheld wireless controller 1 receives the wireless data signal sent by the movable wireless switch group 2, demodulates it into a professional format data packet by the second wireless transceiver component 12, and sends it to the intelligent control system board 14, and the CPU of the intelligent control system board parses, corrects, compares and judges the data packet through a self-programmed special data processing program to form useful parameter information and running state information. The four paths are respectively sent to the self-programmed display processing program, the self-programmed intelligent running processing program, the self-programmed abnormal correction control program and the self-programmed logic storage processing program for related processing.

[0055] 1. The display processing module 141 runs a self-compiled display processing program to extract parameter information and running status information from the data packet, compiles it into display data, and displays it on the LCD touch screen 13 in a specified graphic format to form a human-machine interface for operators to observe and control.

[0056] 2. The self-written intelligent operation processing program is run by the operation processing module 142 to parse the incoming data packets and determine whether an automatic operation control command needs to be initiated. When an automatic operation control command needs to be sent, the program transmits the command data packet to the second wireless transceiver component 12 in the form of a coded data packet with a specified format. The second wireless transceiver component 12 modulates the data packet into a wireless carrier signal and sends it to the movable wireless switch group 2 through the second invisible antenna 11 to control the operation status of the movable wireless switch group 2, so as to achieve the effect of intelligent operation.

[0057] 3. The abnormality correction control module 143 runs a self-compiled abnormality correction control program to parse, compare, and judge the incoming data packets. It checks whether the data packets contain any abnormalities in the operating status of the portable wireless switch group 2. When an abnormality is found, the program will query the pre-compiled abnormality status correction processing list and issue the corresponding correction control command data packet according to the list. The data packet is sent to the second wireless transceiver component 12, which modulates it into a wireless carrier signal and sends it to the portable wireless switch group 2 through the second invisible antenna 11. This performs abnormality protection correction operation of the portable wireless switch group 2 and promptly puts the portable wireless switch group into a safe operating state.

[0058] 4. Using the logic storage module 144, run the self-compiled logic storage processing program to compile the parameter information, status information, alarm information and other related data information in the data packet in the prescribed format, and add time information, operation number information, etc., and store them in the storage module 17 in the form of a file to form a list of running status and control trajectory for future query and analysis.

[0059] When the movable wireless switch group 2 needs to be controlled, the operator inputs the operation instruction through the touch button or mechanical switch button of the liquid crystal display touch screen 13. The button information is sent to the CPU on the system board after being processed by the special circuit of the intelligent control system board 14, and is compiled and processed by the self-programmed operation instruction processing program, the self-programmed display processing program and the self-programmed storage processing program respectively. Among them, the operation instruction program is formed by the self-programmed operation instruction program of the operation processing module 142, the data packet is sent to the movable wireless switch group 2 through the second wireless transceiver assembly 12, and the movable wireless switch group 2 is operated. The button information is processed into graphic information of a specified format by the self-programmed display processing program of the display processing module 141, and is displayed on the liquid crystal display touch screen 13 to form a man-machine interface for the operator to observe and control. The button information is processed into an operation data list by the self-programmed storage processing program of the logic storage module 144, and is stored in the storage module 17 in a specified format with time information and operator ID information to form an operation track record for future query.

The CPU of the data acquisition and instruction control center board 28 analyzes, corrects, compares, judges and sends it to the self-programmed special instruction program to form a control data signal. After signal amplification by the amplification circuit 29, the corresponding electromagnetic valve 23 is controlled to act, driving the pneumatic actuator 23 to drive the movable wireless switch group 2 to operate in opening or closing. The action process is collected by the position sensor 265, and the collected switch state information is sent back to the data acquisition and instruction control center board 28. The data acquisition and instruction control center board 28 processes the information through the switch state processing program to form a special format data packet, which is sent to the first wireless transceiver assembly 25 to form a wireless carrier signal, which is sent to the handheld wireless controller 1 through the antenna. At the same time, the switch voltage data information, the switch temperature information, the pneumatic source pressure value information and the battery capacity information are collected by the voltage sensor 261, the temperature sensor 262, the air pressure sensor 263 and the battery capacity sensor 264 and sent to the data acquisition and instruction control center board 28. The data acquisition and instruction control center board 28 edits and processes the information through the voltage data processing program, the temperature data processing program, the air pressure data processing program and the battery capacity processing program to form a corresponding format data packet, which is sent to the handheld wireless controller 1 through the first wireless transceiver assembly 25 to form a wireless carrier signal through the first invisible antenna 24.
