Embodiment Construction
[0022] Such as figure 1 and figure 2 As shown, an embodiment of the present invention includes a server and a terminal, and the server communicates with the terminal, and the terminal includes a GSM / CDMA subsystem, a GPS subsystem, a ZIGBEE subsystem, an RFID subsystem and a controller, a GSM / CDMA subsystem, and a GPS subsystem , ZIGBEE subsystem, RFID subsystem are connected with the controller.
[0023] Such as image 3 As shown, the terminal login process is as follows: after the terminal is powered on, it starts to start, and judges whether the ZIGBEE network is found. If the ZIGBEE network is found, it joins the ZIGBEE network and sends login information to the server; if the ZIGBEE network is not found, it judges whether the GPRS Or CDMA1X network, if GPRS or CDMA1X network is found, then join GPRS or CDMA1X network, and send login information to the server; otherwise return, re-judging whether ZIGBEE network is found; after sending login information to the server, de...
