The realization method based on ZigBee and the intelligent home appliance system that page generation according to claim 6 is characterized in that the embedded Web gateway can control 65535 terminal devices at most, and each terminal device has a 16-bit network address Number, the network address range is 0x0001~0xFFFF. 9. according to claim 6 based on ZigBee and the realization method of the intelligent home appliance system that page generates, it is characterized in that the instruction that embedded Web gateway sends to terminal equipment when step (3) selects different keys to terminal equipment is divided into two kind: Query command: After the home appliance control page is generated, the user remotely accesses the embedded Web gateway to obtain the command of the terminal device's operating status and temperature and humidity environment parameters; Control command: The user remotely accesses the embedded Web gateway, which is used to control the command issued by the terminal device to complete a certain control function. 10. the realization method based on ZigBee and the intelligent home appliance system that page generation according to claim 6 is characterized in that terminal equipment has two kinds of working states: Executing command status: The terminal device receives the command data issued by the ZigBee coordinator module, and immediately performs corresponding operations on the device after receiving the command; Deep sleep state: The terminal device is in a sleep state. After waking up after a period of sleep, it polls the ZigBee coordinator module. If there is data, it will immediately switch to the execution command state, and if there is no data, it will continue to sleep.
