本发明公开了一种多通道生物信号采集器与传感器的无线连接方法,方法包括:步骤1:接收器上电产生随机信道;步骤2:接收器抢占随机信道,接收器在公共信道发射配对信息,等待传感前端的配对;步骤3:传感前端上电后,进入公共信道接收配对信息,接收器与传感前端配对成功后,接收器从传感前端获取有效数据;步骤4:当接收器与传感前端的通讯信道被干扰,造成数据丢包率达到阈值时,接收器自动扫描空间中可用的空闲信道,并通知传感前端同时切换到新的空闲信道继续工作,实现了多通道生物信号采集器与传感器的无线连接方法配对简单、直观、各无线通道速率独立、稳定、空间容量大的技术效果。
The present invention discloses a method for wirelessly connecting a multi-channel biological signal collector and a sensor. The method includes the following steps: Step 1: a receiver generates a random channel upon power-on; Step 2: a receiver preempts a random channel; a receiver transmits pairing information on a common channel , Waiting for pairing of the sensing front-end; Step 3: After the sensing front-end power-on, entering the public channel to receive the pairing information, the receiver obtains the valid data from the sensing front-end after the pairing between the receiver and the sensing front end succeeds; Step 4: When the data packet loss rate reaches the threshold, the receiver automatically scans the free channels available in the space and notifies the sensing front-end to simultaneously switch to the new free channel to continue working, thus realizing multi-channel Biometric signal acquisition and sensor wireless connection method pairing is simple and intuitive, the wireless channel rate independent, stable, large space capacity of the technical effect.
