example 1
S301, determining the transmission direction of a transmission line according to the actual transmission condition, wherein the transmission line is arranged in a power exchange station for use, a feed battery is required to be transported from the power exchange equipment to a charging bin in the power exchange station, and a full-power battery is required to be transported from the charging bin to the power exchange equipment, so that the transmission line is required to be transmitted in two directions, and a direction instruction transmitted by a main control system is required to be received before the transmission line runs to further determine the transmission direction; in this embodiment, three sections of wire bodies are arranged, and the same transportation direction of the three sections of wire bodies needs to be ensured.

Referring to fig. 3, the signal acquisition module includes an in-place detection sensor 11, a deceleration sensor 12, an in-place detection sensor 13, and an out-of-place detection sensor 14, which are disposed on a conveying line;
the in-place detection sensor 11 is used for detecting whether the material is conveyed to a place or not, the in-place detection sensor 11 is arranged at the front end of the first section of wire body and the tail end of the last section of wire body, when the in-place detection sensor 11 detects the material, the material is transferred to the conveying line from the previous working procedure, and the conveying line can start to operate or stop to operate;
the speed reduction sensor 12 is used for controlling the transportation speed of the wire body, the speed reduction sensor 12 is arranged at the joint of two adjacent wire bodies and used for detecting whether a material is clamped at the joint of the wire bodies, and when the material is clamped at the joint of the wire bodies, the speed of the two wire bodies is indicated to be not matched, so that the speed of the two wire bodies is readjusted;
the in-situ detection sensor 13 is arranged at the middle position of the middle section of the wire body and is used for detecting whether the material reaches the section of the wire body or not and monitoring the position of the material on the conveying line in real time;
the offside detecting sensor 14 is configured to detect whether the position of the material is accurate when the material stops, where the offside detecting sensor 14 is disposed on two sides of the offside detecting sensor 11, that is, on the foremost end of the first section of wire body and the foremost end of the last section of wire body, under normal conditions, when the offside detecting sensor 11 detects the material, the conveying line will stop running, but when the offside detecting sensor 11 or the conveying line is abnormal, the material will continue to be transported along the original transport direction, and when the offside detecting sensor 14 detects the material, it is indicated that the material has been transported and the conveying line needs to be stopped immediately.
