Development of Automatic Crimping System for Transmission Line

There are many links in the construction process of transmission and transformation lines. The construction of wire crimping is a key link. The traditional wire crimping technology needs to manually move the wire during the crimping process. After the crimping, the size of the crimping wire and the distance of the wire moving are manually detected. The operation is cumbersome and the crimping and measuring dimensions are inaccurate. In this paper, an automatic crimping control system for the transmission line is designed with microcontroller as the main controller. The upper computer can manually set the moving distance of the wire and the movement of the wire. It can also show the diameter of the wire after crimping and the pressure at the time of crimping. The lower microcontroller automatically moves the wire according to the instruction of the upper computer, which also measures the three sets of hexagonal conductors against the margins and the pressure of the hydraulic pump output. What it's more, it can display the pressure and the margins on the serial port screen. Comparing with the traditional wire crimping system, the system saves manpower, improves work efficiency and reduces accident rate.
