A star networking method for a biological signal sensor and a collector comprises the following steps: S1, starting; S2, configuring wireless networking parameters; S3, starting networking; S4, judging whether networking succeeds or not; S5, powering on a signal concentrator and a signal terminal again; and S6, enabling the signal terminal in the star network to transmit the acquired correspondingdata and communication state to the signal concentrator at default +20 dBM transmitting power. According to the invention, simple and intuitive wireless networking, network distribution and communication between the multi-channel biological signal collector and the sensor are realized, and the respective data propagation rate, stable bandwidth frequency and other functions are realized among thestar networks, so that the data packet loss rate caused by data collision is avoided in a physical space, and the integrity of the data is greatly ensured in time.
