The duration of the second target time is longer than that of the first target time.
In step S232a, the first target time is typically 30 seconds, and when the goods are placed on the conveying device, the pressure detection is performed every 30 seconds, and when the pressure values obtained by the two detections are the same, the conveying device satisfies the conveying condition, and at this time, the conveying device receives the departure instruction and then conveys the goods directly according to the first conveying signal, but in the process of waiting for the departure instruction, if the detected pressure value changes again, the pressure value needs to be continuously detected.
For example, the currently detected pressure value is 2KN, if 30 seconds elapse, the detected pressure value is still 2KN, at this time, the conveying device satisfies the transportation condition, if 30 seconds elapse, the detected pressure value is 3KN, which indicates that the cargo that the conveying device needs to transport changes, and at this time, the next detection result needs to be waited.
In step S232b, the second target time is typically 3 minutes, that is, after the conveying device reaches the goods placement point, the worker needs to place the goods on the conveying device within 3 minutes, otherwise, the conveying device returns to the conveying waiting position, and in 3 minutes, as long as the goods are placed on the conveying device, the conveying device performs pressure detection every the first target time, and determines whether the transportation condition is met by the method in step S232 a.
It should be noted that, the determination of the transportation condition is mainly aimed at the automatic operation of the conveying device, that is, the worker places the goods on the conveying device without performing subsequent operations, but the operation of the conveying device can also be manually controlled by the start instruction, so long as the goods are placed on the conveying device, and the determination of the transportation condition does not affect the transportation of the conveying device after the start instruction is received.
