The data is transmitted to the analysis unit together; the limited time data and trimmed time are also stored in the database, and the analysis unit obtains the limited time data and trimmed time from the database, and processes them together with the image information and position data. Carry out the analysis operation to obtain the working-hour difference, the corrected difference and the consumption time value, and transmit them to the judgment unit together; The process is: obtain the difference of working hours and the value of consumption time, and bring them into the calculation formula together: stop time = difference value of working hours - value of consumption time, where stop time refers to the stop signal allowed to be issued during this time period; get Correction difference value and consumption time value, and bring them into the calculation formula together: start time = correction difference value - consumption time value, where start time refers to the time period allowed to send the opening signal; The time is transmitted to the control unit and the smart device respectively; the control unit receives the stop time and start time, and controls the start and stop according to them, and the smart device is used to display the stop time and start time, and remind the user.
