Method for tracking and locating container by adopting label sensor network

At present, an RFID (Radio Frequency Identification Device) technology is used in the container physical distribution process, however, the application of the RFID technology in the field of container physical distribution tracking and locating is limited due to defects and limitations of an RFID per se. The invention provides a method for tracking and locating a container by adopting a label sensor network, and in the method, the sensor network is fused with an RFID network, so that transmitting various types of radio frequency label data is realized by a ZigBee network through gateway level design, hardware module design, protocol fusion and the like. By using the label sensor network, the transmission radius of the traditional RFID network is increased, and a series of problems such as incapability of sensing object states, poor an-interference performance and the like of the RFID are solved. Positional information of the container is calculated through a subtriangular inner pointer testing algorithm. Relevant information such as a position, a safety condition, humidity and temperature change and the like of the container can be gotten by a shipper or manager through a computer and a mobile phone, and once unforeseen circumstances such as container damage, transportation line change or delay and the like happen, alarm information can be received in time.
