The invention discloses a
wireless connection method for a multi-channel bio-
signal collector and a sensor. The method comprises the steps of 1, powering on a
receiver to generate a random channel; 2, preempting the random channel by the
receiver, sending the
pairing information to a common channel by the
receiver, and waiting the
pairing at a sensing front end; 3, powering on the sensing front end, receiving the
pairing information through the common channel, and acquiring effective data from the sensing front end by the receiver after the receiver and the sensing front end are successfully paired; 4, on the condition that a data
packet loss rate reaches a threshold to interfere a
communication channel between the receiver and the sensing front end, automatically scanning available idle channels in the space by the receiver, notifying the sensing front end and switching to a new
idle channel to continue the operation at the same time. In this way, the
wireless connection method for the multi-channel bio-
signal collector and the sensor is simple and intuitive in pairing, and the rate of each
wireless channel is independent and stable. Meanwhile, the space capacity is large.
