The area time threshold represents the minimum time for workers or equipment to stay in the work area and work location. The setting method of the area time threshold is: given the respective initial time thresholds of the work area and work location, a certain amount of business information is entered and used The maximum likelihood estimation gives a new probability density model based on normal distribution, and sets the confidence interval to obtain a new time threshold. When it is determined that the positioning tag corresponding to the worker or equipment is in the corresponding working area, it is judged whether the working area where the positioning tag is located is the operation record stay area. If so, it means that the operation is still continuing. Record the end time of this job.

S105. According to the business information table, determine the order in which the same worker or equipment arrives at each work area in the warehouse within the set time period, and determine the type of operation performed by the corresponding worker or equipment according to the order of arrival at each work area in the warehouse, and classify the operation type Enter the business information form.

In specific implementation, the specified working area can be used as the starting point, and several working areas where the same worker or equipment stays in the corresponding positioning tags within the set period of time are connected in sequence to form an area-oriented movement path; the area-oriented movement path is substituted into the preset job type Compare with the regional directional movement table, and determine the corresponding operation type.
