Problems solved by technology
[0003] Because the different crystal oscillators used in the clock source of each base station have different frequency deviations, and the frequency deviation shows a non-linear change with temperature changes, therefore, clock synchronization between base stations is particularly difficult

The invention relates to a self-adaptive wireless synchronization method based on an ultra-wideband technology. The self-adaptive wireless synchronization method comprises the following steps of: acquiring a first frame synchronization frame message at a first moment and transmitting the first frame synchronization frame message to a network; receiving a first synchronization message returned by the first slave base station and the first relay base station, and acquiring a first receiving moment of receiving the first synchronization message; acquiring a second frame synchronization frame message at a second moment and transmitting the second frame synchronization frame message; receiving a second synchronization message returned by the first slave base station and the first relay base station, and acquiring a second receiving moment of receiving the second synchronization frame message; and calculating the time after the first slave base station and the first relay base station are synchronized according to the first moment, the first receiving moment, the second moment and the second receiving moment. In the self-adaptive wireless synchronization method, the slave base station and the relay base station are subjected to time synchronization through the time received twice, the operation is simple and convenient, the operand is small, the arrangement of the base stations can be reduced, and the convenience of clock synchronization between the base stations can be improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to an adaptive wireless synchronization method, device, computer equipment and storage medium based on ultra-wideband technology. Background technique [0002] In the field of computer technology, positioning technology is used more and more frequently. In various real-time positioning systems, data acquisition and real-time control must have a unified clock for the entire network. The accuracy of the clock will have a greater impact on the collected data. Once the clock deviation occurs, it will cause some data to fail and affect positioning accuracy. Positioning by base station clock is a common way of positioning. The base station has its own independent clock source. The clock source is used to provide the ring pulse generator with a square wave clock signal with stable frequency and level matching. It is usually composed of a positive feedback oscillation circuit co...
