AI Technical Summary

Problems solved by technology

Since both the synchronization signal and the position data are sent by wireless transmission, if the time when the base station sends the synchronization signal and the time when the handle sends the position data overlaps or nearly overlaps, it will cause electromagnetic waves in the air to interfere and cause the synchronization signal to be lost.

Abstract

The invention discloses a signal transmission control method, device and system, which are used for controlling the moment when a device to be located transmits locating data to a control device by using a wireless transmission mode, wherein the device to be located determines the locating data by receiving locating signals periodically sent via a signal transmitter and a synchronous signal sent by using a wireless transmission manner; the signal transmission control method comprises the steps of determining the moment when the device to be located receives the synchronous signal according tothe moment when the signal transmitter sends the synchronous signal; determining the moment when the device to be located sends the locating data according to the moment when the device to be locatedreceives the synchronous signal and the length of a signal period, wherein the moment when the device to be located sends the locating data is not overlapped with the moment when the signal transmitter sends the synchronous signal.

Description

technical field [0001] The present invention relates to signal transmission technology, in particular to a signal transmission control method, device and system. Background technique [0002] At present, indoor positioning can be realized by using UWB (Ultra Wideband, pulse radio) positioning technology, laser positioning technology, high-speed camera positioning technology, visible light positioning technology, ultrasonic positioning technology, etc. In an optional implementation of laser positioning technology, the base station can use wireless transmission to send synchronization signals, and also send rotating laser surface signals for spatial scanning.
