In order to realize the control method, the battery pack transmission control system is provided with a signal acquisition module for acquiring the position of a material on a conveying line; the wire body control module is arranged and used for controlling the running state of the motor on each section of wire body and adjusting the motor through speed and torque; the system comprises a line body monitoring module, a data processing module and a data processing module, wherein the line body monitoring module is used for monitoring the real-time speed and torque of the operation of a motor on each section of line body and giving an alarm when the line body is abnormal; setting an exception handling module for receiving various alarms issued by the system and processing the alarms; the system has simple and practical structure and great advantage in cost, and is favorable for large-area popularization in the battery replacement station.
Referring to fig. 3, the signal acquisition module comprises an in-place detection sensor 11, a deceleration sensor 12, an in-place detection sensor 13 and an offside detection sensor 14 which are arranged on the conveying line;
when the in-place detection sensor 11 detects the material, it indicates that the material has been transferred onto the conveying line from the previous procedure, and the conveying line can start to run or stop running;
the speed reduction sensor 12 is used for controlling the conveying speed of the line body, the speed reduction sensor 12 is arranged at the splicing position of two adjacent line bodies and is used for detecting whether materials are clamped at the joint of the line bodies, when the materials are clamped at the joint of the line bodies, the speed of the two line bodies is not matched, and therefore the speed of the two line bodies is readjusted;
the in-situ detection sensor 13 is arranged in the middle of the middle section line body and used for detecting whether the material reaches the middle section line body or not and monitoring the position of the material on the conveying line in real time;
the offside detection sensor 14 is used for detecting whether the position of a material is accurate when the material stops, the offside detection sensors 14 are arranged on two sides of the in-place detection sensor 11, namely the most front end of the first section of line body and the most tail end of the last section of line body, under a normal condition, after the in-place detection sensor 11 detects the material, the conveying line stops running, however, when the in-place detection sensor 11 or the conveying line is abnormal, the material can be continuously conveyed along the original conveying direction, and at the moment, when the offside detection sensor 14 detects the material, the material is conveyed out of position, and the conveying line needs to be stopped immediately.
