A monitoring method for a shared recyclable logistics tool, comprising the following steps: a recyclable logistics tool is shared by multiple users in a time-shared manner, valid area sets corresponding to each user are stored in a server, and each valid area set contains one or more geographic areas; obtaining continuously the tool identifier and positioning information of the recyclable logistics tools by the server via a cellular wireless communication module provided in the recyclable logistics tool by registering the cellular wireless communication module to a base station, transmitting a cellular wireless signal carrying the tool identifier to the server, and approximating the positioning information from the position of the base station to which the cellular wireless communication module is registered; querying the valid area set corresponding to the current user of the recyclable logistics tool according to the tool identifier; giving out an alarm, if it is determined, according to the positioning information, that the recyclable logistics tool camp outside the geographic areas in the queried valid area set and the camping duration exceeds a predetermined threshold, wherein, if the positions of the logistics tool within a certain period of time are concentrated in a certain radius area which is outside the geographic areas in the queried valid area set, it is then determined that the logistics tool camps outside the geographic areas in the queried valid area set. a recyclable logistics tool is shared by multiple users in a time-shared manner, valid area sets corresponding to each user are stored in a server, and each valid area set contains one or more geographic areas; obtaining continuously the tool identifier and positioning information of the recyclable logistics tools by the server via a cellular wireless communication module provided in the recyclable logistics tool by registering the cellular wireless communication module to a base station, transmitting a cellular wireless signal carrying the tool identifier to the server, and approximating the positioning information from the position of the base station to which the cellular wireless communication module is registered; registering the cellular wireless communication module to a base station, transmitting a cellular wireless signal carrying the tool identifier to the server, and approximating the positioning information from the position of the base station to which the cellular wireless communication module is registered; querying the valid area set corresponding to the current user of the recyclable logistics tool according to the tool identifier; giving out an alarm, if it is determined, according to the positioning information, that the recyclable logistics tool camp outside the geographic areas in the queried valid area set and the camping duration exceeds a predetermined threshold, wherein, if the positions of the logistics tool within a certain period of time are concentrated in a certain radius area which is outside the geographic areas in the queried valid area set, it is then determined that the logistics tool camps outside the geographic areas in the queried valid area set.
