A signal recognition system, a positioning system, a positioning base station and a signal recognition method

Abstract

The invention discloses a signal identification system and method, a positioning system and a positioning base station. The signal identification system comprises an emitter, a signal identifier and a data processor; the emitter comprises at least a first optical signal generator and a second optical signal generator; the first signal generator includes a linear light source used to generate scanning positioning optical signals; the second optical signal generator includes a surface light source to generate synchronous optical signals; the signal identifier comprises optical sensors, an included angle between a connecting line, between positions of any two optical sensors, and a scanning plane corresponding to the first signal generator is not zero, and the distance between any two optical sensors is greater than a preset value; and the data processor is connected with the signal identifier, and is used to determine the type of the optical signal according to time difference between optical signals emitted by the emitters and received by the optical sensors. The reliability of the signal identification system can be improved.

Description

technical field [0001] The invention relates to the field of space positioning, in particular to a signal identification system, a positioning system, a positioning base station and a signal identification method. Background technique [0002] With the development of science and technology, there are more and more types of electronic devices, and more and more electronic devices need to perform synchronous cooperation. [0003] Since the time in each electronic device may be different or inconsistent, and some electronic devices do not even record the time, it is necessary to perform synchronization processing when multiple electronic devices perform synchronous cooperation, especially for some time accuracy and signal reliability requirements. Very high occasions, for example: two positioning base stations cooperate synchronously to locate objects in space through laser signals. [0004] When two positioning base stations cooperate synchronously, in the current synchroniza...
