The two small cars of the aluminum profile tractor run back and forth on a track ranging from 50 meters to 100 meters for aluminum profile traction. In traditional technology, the aluminum profile tractor uses a sliding contact line to communicate and exchange data between the two small cars and the host. The 380V AC power line of the two small cars is also provided to the two small cars through the sliding contact line.
The host sends signals to two small cars (car I and car 2 respectively) through sliding contact lines, thereby controlling the clamping and releasing of the fixture of car I, the starting and stopping of the saw blade motor of car I, and the pushing and pulling out of the cylinder of car I; Control the clamping and releasing of the fixture of car 2; Control the cylinder propulsion, withdrawal, etc. of car 2.
The sliding contact wires used for the 380V AC power supply and communication on the car are installed side by side, which can cause electromagnetic interference during the back and forth sliding of the car. In addition, the production environment of aluminum profile manufacturers is relatively harsh, usually with high temperature, vibration, etc., which makes the communication data transmission between the host and the two cars easily interrupted, causing machine shutdown and affecting production efficiency and product quality.
