The invention discloses a wireless co-frequency signal category detection device, method and system based on a packet error rate. The device comprises a darkroom, a transmitter, a receiver, a PC, a WIFI signal transmitting module, a Bluetooth signal transmitting module and an RFID signal transmitting module. The transmitter, the receiver, the WIFI signal transmitting module, the Bluetooth signal transmitting module and the RFID signal transmitting module are located in the darkroom. The distance from the WIFI signal transmitting module, the Bluetooth signal transmitting module and the RFID signal transmitting module to the receiver is equal. The distance is set as first distance. The distance between the transmitter and the receiver is set as second distance. The first distance is smallerthan the second distance. The PC is connected with the receiver. The PC is used for displaying the packet error rate. Through adoption of the device, the method or the system provided by the invention, wireless interference signal identification problem in wireless sensor network ZigBee communication can be solved.
Description
Technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless co-frequency signal category detection device, method and system based on packet error rate. Background technique [0002] With the development of wireless networks and the Internet of Things, especially some short-distance wireless co-frequency networks will be deployed in the same environment, such as intelligent buildings, agricultural Internet of Things and other application systems. ZigBee, Bluetooth, WiFi and RFID all work on the ISM2.4GHz frequency band. The ISM frequency band is a free universal frequency band around the world. Under the same environment, multiple wireless signals using the same frequency band or similar frequency bands will cause interference. For those with low power, data Equipment with slow transmission will cause delays, loss of data, and even wrong data. Especially for those fire-fighting equipment and alarm devices that use Z...
