GPS terminal equipment and communication system

The embodiment of the utility model discloses a global positioning system terminal device and a communication system. The global positioning system terminal device comprises a wireless communication module used for acquiring the state information locked by an electronic signature as well as a global mobile communication system module used for transmitting the state information acquired by the wireless communication module to a real-time monitoring platform system. In the embodiment of the utility model, the electronic signature lock transmits the state information to the real-time monitoring platform system through the global positioning system terminal device, thus the electronic signature lock can communicate with and transmits data to the real-time monitoring platform system through the global positioning system terminal device. Therefore, the real-time monitoring platform system can carry out real-time monitoring for the electronic signature lock.
