Problems solved by technology

The fixed-frequency amplifier circuit increases the receiving distance of the infrared module, but it also leads to the deterioration of the directional performance of infrared communication: for example, at a short distance, due to the scattering of light by the environment, even if the transmitter is facin

Abstract

The invention discloses an automatic follow-up control method and system based on infrared signal. The invention is provided with an asymmetrically distributed infrared receiving tube on the infraredreceiving module. The infrared signal from the infrared transmitting module is received through the asymmetrically distributed infrared receiving tube. According to the regional orientation of the received infrared signal, the main direction of the infrared receiving module is gradually aligned with the infrared transmitting module. At the same time, during the alignment process, the intensity ofthe infrared signal is gradually reduced to obtain the critical strength of the infrared signal transmitted to the receiving module. Therefore, the automatic follow-up control method and system basedon infrared signal can calculate the distance between the infrared transmitting module and the receiving module according to the intensity of the infrared signal, while performing high-precision fastdirection finding, and drive the infrared receiving module to achieve follow-up control. The automatic follow-up control method and system based on infrared signal can reduce the precision requirementof the infrared device by the cooperation of the hardware circuit and the control unit, and achieve high-precision direction finding and fast following under the premise of a small number of infraredreceiving modules, thereby reducing the hardware cost.

Description

technical field [0001] The invention relates to sensor technology, in particular to a method and system for measuring direction and distance. Background technique [0002] Auto-following car can automatically track the movement of the target, automatically follow the car to follow the target, target forward, automatically follow the car forward; target backward, automatically follow the car backward; target to the left, automatically follow the car to the left; target to the right, Automatically follow the car to the right; when the target stops, the automatic following car also stops; the ideal following mode should keep the 12 o'clock direction (head direction) of the automatic following car facing the target and keep it in the 6 o'clock direction of the target. Therefore, the automatic following vehicle is expected to provide users with services such as accompanying or assisting in the handling of heavy objects. To realize the automatic tracking of the target by the auto...
