Abstract:
1. A control method for a heterogeneous wireless sensor network (WSN) bridging device, applicable to control a heterogeneous WSN bridging device, wherein the heterogeneous WSN bridging device comprises a Zigbee transceiver module, a wireless network transceiver module, and a processor, the heterogeneous WSN bridging device is used for bridging a plurality of Zigbee sensor nodes and a remote main control device, the method comprising: switching the wireless network transceiver module to an active mode, and receiving a first task list from the remote main control device by the wireless network transceiver module; switching the wireless network transceiver module to a sleep mode, and switching the Zigbee transceiver module to an active mode; transmitting an operating instruction to the Zigbee sensor nodes by the Zigbee transceiver module according to the first task list; receiving at least one sensing signal from the Zigbee sensor nodes respectively, and storing the sensing signals; and determining whether the sensing signals have been received according to the first task list; if yes, executing a back transmission procedure, wherein the back transmission procedure comprises: switching the Zigbee sensor nodes to the sleep mode, and switching the wireless network transceiver module to the active mode; and transmitting the sensing signals to the remote main control device by the wireless network transceiver module.
