[0021] The mailbox control terminal device S101 works in an energy-saving mode, that is, the main module is in a sleep state at ordinary times, only a weak current is needed to ensure the work of the main control microprocessor kernel, the remaining power and wireless signal are measured at regular intervals, and the results are reported to the management platform S103, and then the main module reenters the sleep state; when the letter monitoring unit detects that a letter is put in, or the door opening and closing detection unit detects the opening or closing action, the main module is awakened and the event is reported to the management platform S103, and then the main module reenters the sleep state until the next awakening.

[0022] The management platform S103 manages a plurality of remote mailbox control terminals S101 through a mobile network, receives the information reported by the mailbox control terminal, parses the message content according to the interface protocol defined in advance by the management platform and the control terminal, and processes as follows:

[0023] If the terminal reports the remaining power and the wireless signal measurement result regularly, the data of the relevant terminal in the database is updated; if the remaining power is less than the pre-set threshold, the alarm processing procedure is entered, i.e. alarm information is sent to the system user and the task of replacing the battery of the mailbox is added in the next field task; if the wireless signal is weaker than the pre-set threshold and the previous N-1 regular reporting values are all weaker than the pre-set threshold, it is determined that the antenna feeder part of the control terminal is faulty, at this time, alarm information is sent to the system user and the task of detecting the antenna feeder part of the mailbox is added in the next field task.

[0024] If the terminal reports the depositing event, the data of the relevant terminal in the database is updated and the task of taking the deposit of the mailbox is added in the next field task.

[0025] If the terminal reports the opening and closing events of the mailbox, the data of the relevant terminal in the database is updated and the field task being performed is checked to determine whether the opening and closing events of the mailbox are legal; if there is no task of taking the deposit, replacing the battery or detecting the wireless module antenna feeder of the mailbox in the field task, it is determined that the mailbox is possibly opened illegally, at this time, alarm information is sent to the system user so as to take further measures.

[0026] The management platform can also provide various statistical information to the user based on the data reported by the control terminals of the mailboxes, such as the statistics of the mail of a single, a certain area or all mailboxes in the city according to time period, the execution time statistics of the taking deposit task of each route, etc., which are beneficial to the reasonable arrangement of human resources and the improvement of labor efficiency of the postal system.

[0027] Those skilled in the art should understand that although the above embodiment takes the wireless module and the mobile network as an example to illustrate the system structure, it does not constitute a special limitation, in fact, any wireless communication network providing wide area coverage and the corresponding wireless module are suitable for the utility model based on the same utility model concept.
