Beidou satellite timing system and method

Abstract

The invention discloses a Beidou satellite timing system and method. By the adoption of the Beidou satellite timing system and method, Beidou satellite time signals can be read and stably displayed in real time through an LED dot-matrix display screen, and network time synchronization is conducted on network devices in a wireless network. According to the Beidou satellite timing system and method, a satellite navigation message is received through a Beidou navigation module and a GPS navigation module, whether locating conducted by the Beidou navigation module succeeds or not is judged through a field-programmable gate array module, and universal time is extracted, converted and displayed by the LED dot-matrix display screen; a micro control unit judges whether a network timing requirement or a dot-matrix brightness adjustment request is received or not; if yes, time information is added to a network time protocol transmitted in the wireless network for network time synchronization or brightness is adjusted by adjusting the gate time of a dot matrix, and if not, judgment continues. The Beidou satellite timing system and method achieve LED dot-matrix display of time service and the network time synchronization function and are wide in application range, and the stability of the system is high.

AI Technical Summary

Problems solved by technology

However, the deficiencies that still exist in this patent are: 1. Although the device has a time service function, it does not have a network time service function, and its interconnectivity is relatively low, which is not conducive to communicating with devices with network functions, and its application range is small

2. The device does not display the time service time, which is not intuitive

However, the deficiencies still exist in the system of this patent are: although the patent realizes the time service function, it does not display the time, and the system does not have the network time service function, so the scope should be limited

However, the method of this patent still has the disadvantages that: this method can lead to timing errors in an environment where the Beidou signal is weak, and the system stability is not high
