Problems solved by technology

[0004] This solution has the following problems: firstly, it is easily affected by obstacles; secondly, it is easily affected by other ultrasonic devices; thirdly, the coverage is small, and the automatic tracking device and the target to be followed can only be detected within the effective distance of ultrasonic waves within 4m ; Fourth, the target wireless transceiver module needs to work for a long time and consumes a lot of power
[0006] This scheme has the following problems: the distance is calculated according to the signal strength, and the signal strength is greatly affected by the interference of the transmitted signal power, weather, and transmission path, so the positioning accuracy is poor

Abstract

The invention discloses a system for achieving automatic following based on an antenna array. The system comprises an automatic following device and a followed target, wherein a motor drive module, M antennas and M communication modules are arranged on the automatic following device, and M is more than and equal to 4; the M antennas are uniformly distributed on a same plane at an internal of 360 / M degrees; each antenna is connected with the corresponding communication module; the communication modules are connected with a central control module; the central control module is also connected with the motor drive module; and the motor drive module drives the automatic following device to move towards the direction of the followed target.

Description

technical field [0001] The present invention relates to the technical field of automatic tracking, in particular to a system and method for realizing automatic tracking based on an array antenna. Background technique [0002] At present, the automatic following technology in the wireless network is based on ultrasonic ranging technology and 2.4G wireless ranging technology, which are basically based on the distance between the multiple wireless module antennas on the automatic following device and the wireless module antennas on the target to be followed. Determine the distance between the automatic following device and the followed target, as well as the angular relationship between the two, and then control the automatic following device to move towards the followed target by controlling the motor on the automatic following device. It mainly includes the following two options: [0003] 1. There is a 2.4G wireless transceiver module on the automatic following device, and 8...
