Embodiment 1
[0033] Such as figure 1 Shown, the embodiment of a kind of Zigbee network of the present invention and WiFi coexistence device, described device comprises Zigbee antenna module, WiFi antenna module, control unit, described control unit connects WiFi antenna module, and described Zigbee antenna module is used for connecting Enter the Zigbee data stream, the WiFi antenna module is used to access the WiFi data stream, the control unit is used to access the Zigbee enabling signal and the WiFi enabling signal, and the control unit is used to control the disconnection and connection of the WiFi antenna module.
[0034] In this solution, the disconnection and connection of the WiFi antenna module is controlled by the control unit, the control unit is connected to the Zigbee enable signal, and the communication status of the Zigbee network is detected through the Zigbee enable signal, and the WiFi antenna module can be disconnected during the Zigbee network communication. For WiFi dat...
Embodiment 2
[0036] Such as figure 2 As shown, the second embodiment of a Zigbee network and WiFi coexistence device of the present invention, the device includes a Zigbee antenna module, a WiFi antenna module and a control unit, including an NPN transistor. The Zigbee antenna module includes a Zigbee radio frequency switch and a Zigbee antenna connected to each other. The WiFi antenna module includes a WiFi radio frequency switch and a WiFi antenna connected to each other.
[0037] The NPN transistor is provided with a base, an emitter and a collector, the base is used to access the Zigbee enabling signal, the collector is connected to the initial WiFi enabling signal through a resistance of 10K ohms, and the collector A WiFi radio frequency switch is connected between the resistor and the resistor, and is used for sending a final WiFi enabling signal to the WiFi radio frequency switch. The emitter is grounded.
[0038] The control unit uses the NPN transistor and the auxiliary circui...
Embodiment 3
[0041] Such as image 3 Shown, a kind of Zigbee network and WiFi coexistence method based on above-mentioned device of the present invention, described method comprises the following steps:
[0042] The S101 control unit accesses the Zigbee enabling signal and the WiFi enabling signal.
[0043] S102 according to the state of the Zigbee enabling signal, the control unit inverts the WiFi enabling signal and sends it to the WiFi antenna module for transmission, and controls the transmission of the WiFi antenna module to disconnect or connect.
[0044] The Zigbee enabling signal and the WiFi enabling signal are control signals for controlling the Zigbee antenna module and the WiFi antenna module to be turned on and off. By accessing the control unit, the Zigbee enabling signal is monitored, so as to realize the monitoring of the Zigbee transmission request. Moreover, the control of turning on and off of the WiFi antenna module is realized by forwarding and negating the WiFi enab...
