Embodiment 1

[0046] The method for obtaining projection based on distance detection or phase detection proposed in the embodiment of the present invention, combined with figure 1 , the method includes:

[0047] The transmitter 3 in the transmitter array transmits the positioning signal 4 to the guide rail belt 6 and the guide rail belt surrounding environment 7, and the positioning signal 5 reflected by the guide rail belt 6 and the guide rail belt surrounding environment 7 is received by the receiver array; The distances from the surrounding environment 7 to the transmitter-receiver array are different, and the receivers at different positions of the receiver array use the reflected positioning signal 5 to perform distance detection or phase detection. The results are different, and the detected distance or phase is within the set range of the receiver 9 forms a projection 8 on the background of receivers that detect other distances or phases.

Abstract

The invention provides a projection data acquisition method of a guide rail band for positioning. The method is implemented in a way that a receiver array includes two or more receivers, the guide rail band and the surrounding of the guide rail band reflect a positioning signal or process a signal generated by a light source to form a positioning signal, the receiver array simultaneously receives the positioning signals reflected or processed by the guide rail band and the surrounding of the guide rail band, and by comparing detection results of signals received by the two different ways, the projection of the guide rail band on the receiver array is obtained. When the guide rail band is a magnetic stripe, the projection of the guide rail band on the receiver array is obtained based on the magnetic field intensity detection or the magnetosensitive switch detection. The projection data acquisition method of the guide rail band for positioning can accurately and effectively obtain the projection data of the guide rail band, and achieve anti-interference positioning.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method for acquiring projection data of a guide rail belt for positioning. Background technique [0002] Chinese patent CN2017100505762 and U.S. patent US15344519 proposed a method of positioning guidance through projection. These two patents mentioned the method of obtaining the projection of the guide rail on the receiver array based on the difference in signal strength received by the receiver at different positions. The signal is light wave, electromagnetic wave or ultrasonic wave. Signal strength characterizes the magnitude of the positioning signal. [0003] Signal strength is susceptible to interference, and the projection acquisition methods proposed in the above two patents have poor anti-interference performance. And the positioning signal is limited to light wave, electromagnetic wave or ultrasonic wave. Contents of the invention [0004] The present i...
