sc: after the total maintenance times and the maintenance completion times of maintenance personnel are obtained, comparing the maintenance completion times with the total maintenance times to obtain a completion percentage, and marking the completion percentage as WZ;
sd: normalizing the registration time length, the average value time length and the completion percentage of the maintainer, and taking the numerical value to obtain the gas maintenance value of the maintainer; and the generated gas dimension effect value is sent to a server for storage and refreshing.
3. The integrated pneumatic control feedback device electromagnetic valve according to claim 1, wherein the server further comprises a registration login module and a division marking unit, wherein the registration login module is used for registering personnel information submitted by a maintenance personnel of the pneumatic valve through a mobile phone terminal and sending the personnel information which is successfully registered to the server for storage, the server marks the personnel maintaining the valve body which is successfully registered as a registration personnel, and the time when the personnel information is received is marked as the registration time of the registration personnel; the personnel information comprises the name, the mobile phone number, the age and the maintenance area of maintenance personnel corresponding to the pneumatic valve;
the dividing and marking unit marks a plurality of pneumatic valves as 1, 2, 3, … … and i in sequence, then the marked pneumatic valves are sent to a mobile phone terminal for display, a maintainer inputs the positions of the pneumatic valves and generates valve body information, and the generated valve body information is sent to a server for storage; wherein the position of the pneumatic valve comprises a zone position and an installation position.
