Abstract
The application relates to a servo electric wrench multi-machine linkage control system which comprises an upper computer, a lower computer, a servo electric wrench and a detection module; the upper computer sends a working parameter signal to the lower computer through serial communication; the lower computer converts the working parameter signal into a control signal and sends the control signal to the servo electric wrench through an IO port; the servo electric wrench locks the task according to the control signal; the detection module is used for detecting the working state of the servo electric wrench and transmitting working state information to the upper computer through serial communication; and the serial communication is Modbus RTU communication. The servo electric wrench multi-machine linkage control system can connect multiple lower computers and servo electric wrenches with one upper computer, parameters can be conveniently unified, changed and debugged, IO port communication and serial communication are mixedly used, the advantages of IO port control, such as good real-time performance, strong stability and large information carrying capacity, are exerted, and the disadvantages of using only IO port control, such as complicated wiring, time and labor consumption of parameter debugging, are avoided.
