Guidance system and control method

The present invention relates to a system and method for controlling guide. The guide system comprises a self-propelled robot may be a signal generator, a signal generator connected to the cable, the sensor is installed and the environment surrounding the detection signal of the sensing module has an automatic device adaptation mode and the sensing mode, the adaptation mode intensity values ​​identifying the environment of the sensor signal, based on the intensity values ​​of the identified set of operating parameters of the sensor so that the sensor working under the operating parameters module can filter out signals below a certain intensity value; the sensing mode, the sensing module in the set working parameters. Guide system of the present invention enables the sensing module sensing mode can only detect the signal strength of a particular signal strength of the boundary of the system corresponding to the filtered signal is below a certain intensity, so that the adjacent interference signal system filtered, to avoid interference with signals of adjacent sensing system module, an improved overall system noise immunity.
