3) microcontroller controls the first wireless launcher to carry out respective wireless instruction according to the wireless data information receivedThe transmission of signal；
4) whether the wireless launcher of microcontroller real-time judge second is needed to send data message, and step is entered if "Yes"5)；Step 1) is backed into if "No"；
5) microcontroller controls the second wireless launcher to carry out respective wireless instruction according to the wireless data information receivedThe transmission of signal, then repeat step 1)；
The priority that the first above-mentioned wireless launcher sends data message is sent without line number higher than the second wireless launcherIt is believed that the priority of breath.
Preferably, the first above-mentioned wireless launcher and the first wireless receiver transmission ZigBee wireless communication datas.
Preferably, the second above-mentioned wireless launcher and the second wireless receiver transmission WiFi wireless communication datas.
Preferably, the wireless hair of the first above-mentioned wireless receiver, the second wireless receiver, the first wireless launcher and secondEmitter carries out the transmission of wireless data signal based on the same antenna.

Embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and accompanying drawingBright, the content that embodiment refers to not is limitation of the invention.
Shown in reference picture 1, the jamproof device of a kind of shared channel of the invention, refer specifically to route for a kind of wireless networkEquipment, it includes：First wireless launcher, the second wireless launcher, the first wireless receiver, the second wireless receiver, micro-controlDevice, antenna and memory processed, the microcontroller are connected with above-mentioned each part respectively, first wireless launcher, first wirelessReceiver and the second wireless launcher, the second wireless receiver are in same band operation, are carried out respectively respectively by the antenna of connectionFrom the transmission of wireless data；The working condition of each transmitter of microprocessor control and receiver, microcontroller real-time judge firstWhether wireless launcher needs to send data message, and when needing to send, microprocessor control closes the second wireless launcher, theThe data transfer of one wireless receiver and the second wireless receiver；When not needed, then judge whether the second wireless launcher needsData message is sent, microprocessor control closes the first wireless receiver, second if the second wireless launcher needs to sendThe data transfer of wireless receiver, microcontroller compartment of terrain switches first and wirelessly connect if the second wireless launcher need not be sentDevice is received with the second wireless receiver to carry out data transmission.
Specifically, the first above-mentioned wireless launcher be ZigBee transmitter modules, the first wireless receiver be that ZigBee connectsReceive module, the second wireless launcher be WiFi transmitter modules, the second wireless receiver be WiFi receiving modules, respectively with microcontrollerDevice is connected, and by the respective working condition of microprocessor control, memory memory storage controls the programmed instruction number of each wireless moduleAccording to when the above-mentioned each wireless module of microprocessor control works, the priority orders controlled are：It is ZigBee transmitter modules first；Secondly it is WiFi transmitter modules；It is finally ZigBee receiving modules and WiFi receiving modules；I.e. microcontroller is preferentially analyzedWhether ZigBee transmitter modules are needed to send ZigBee wireless data informations, and when needing to send, microcontroller is opened by radio frequencyThe data transfer that WiFi transmitter modules, ZigBee receiving modules or WiFi receiving modules are closed in control is closed, it is wireless to carry out ZigBeeThe transmission of data message；When that need not send ZigBee wireless data informations, then whether microcontroller analysis WiFi transmitter modules needWiFi wireless data informations are sent, when needing to send, then microcontroller is controlled by RF switch closes ZigBee receptionsThe data transfer of module, WiFi receiving modules, carry out the transmission of WiFi wireless data informations；As ZigBee transmitter modules and WiFiWhen transmitter module need not send wireless data, then microcontroller compartment of terrain switching ZigBee receiving modules receive mould with WiFiBlock carries out data transmission, and the switching time of the two switches at intervals of Millisecond；
In the jamproof device of shared channel of the present invention, ZigBee transmitter modules, ZigBee receiving modules, WiFi transmittingsModule, WiFi receiving modules can share an antenna, that is, support the antenna of 2.4GHz frequency ranges, and each module passes through 2.4GHz frequency rangesAntenna carries out the transmission of wireless data, the ZigBee and WiFi execute program instructions that microcontroller is contained by memory internal memoryCoded data is controlled to each module transceiving data, is controlled according to the priority of above-mentioned each module, that is, is controlled antennaThe reception or transmission of a kind of wireless data signal are within a specified time only carried out, avoids the wireless signal of same frequency range different agreementThe problem of channel disturbance occurs when transmitting at the same time, influence the transmission quality of ZigBee wireless signals.
Shown in reference picture 2, a kind of shared channel anti-disturbance method of the invention, including step are as follows：
Step 11：Microcontroller compartment of terrain switches the first wireless receiver, the second wireless receiver receives the external world without line numberIt is believed that number；Microcontroller controls ZigBee receiving modules (i.e. the first wireless receiver) and WiFi to connect by controlling RF switchThe data transmission state of module (i.e. the second wireless receiver) is received, compartment of terrain collects corresponding wireless data signal, between the twoSelf-defined setting, preferably Millisecond can be carried out as needed every the time；
Step 12：Microcontroller according to the extraneous wireless data signal real-time judge ZigBee transmitter modules received (i.e.First wireless launcher) whether need to send data message, step 13 is entered if "Yes"；Enter step 14 if "No"；
Step 13：Microcontroller is analyzed the wireless data information received, and in corresponding to extraction in memoryWireless instructions coded data controls the first wireless launcher to carry out the transmission of respective wireless command signal, while passes through RF switchThe data transfer of WiFi transmitter modules, ZigBee receiving modules or WiFi receiving modules is closed in control；
Step 14：Whether microcontroller real-time judge WiFi transmitter modules (i.e. the second wireless launcher) need to send dataInformation, step 15 is entered if "Yes"；Step 11 is backed into if "No"；
Step 15：Microcontroller controls WiFi transmitter modules progress respective wireless to refer to according to the wireless data information receivedThe transmission of signal is made, then repeat step 11；
The priority that above-mentioned ZigBee transmitter modules send data message sends wireless data higher than WiFi transmitter modulesThe priority of information.
Concrete application approach of the present invention is a lot, and described above is only the preferred embodiment of the present invention, it is noted that forFor those skilled in the art, under the premise without departing from the principles of the invention, some improvement can also be made, thisA little improve also should be regarded as protection scope of the present invention.
