Embodiment 1
[0029] Please refer to Figure 1-Figure 2 , the present application provides a wireless connection method between a multi-channel biological signal collector and a sensor. The sensor includes two parts: a receiver and a sensing front end. The receiver is inserted into the acquisition channel of the multi-channel biological signal collector. Methods include:
[0030] Step 1: The receiver is powered on to generate a random channel;
[0031] Step 2: The receiver seizes a random channel, and the receiver transmits pairing information on the public channel, waiting for the pairing of the sensor front end;
[0032] Step 3: After the sensor front-end is powered on, enter the public channel to receive pairing information. After the receiver and the sensor front-end are successfully paired, the receiver obtains valid data from the sensor front-end;
[0033] Step 4: When the communication channel between the receiver and the sensor front-end is interfered, causing the data packet loss...

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.
Description
technical field [0001] The invention relates to the field of multi-channel biological signal acquisition, in particular to a wireless connection method between a multi-channel biological signal collector and a sensor. Background technique [0002] At present, the collection of biological signals consists of multi-channel biological signal collectors and various sensors. The sensors are connected to each channel of the collector through wires, and each channel collects corresponding sensor data independently. The more sensors connected to the collector, the more connecting wires. Excessive wires make the system complicated, and at the same time, the wires are tied to the sensor, which affects the placement of the sensor on the organism, and even causes the sensor to fall off, resulting in acquisition failure. [0003] In addition, the existing wireless transmission scheme has certain limitations in this application. For example, wifi, bluetooth and other solutions, device ...
