Problems solved by technology
At the same time, the single-time base time synchronization device cannot provide normal time service to the electric energy meter when the time source signal is unstable or the receiver is abnormal, and the existing time synchronization device lacks the time source signal verification function. Unable to report to the main station, which will lead to the decrease of the clock accuracy of the electric energy meter, the reliability of the uploaded data is low, which is not conducive to the status evaluation of the power grid, and will even cause huge economic losses

The invention relates to a novel electric energy meter double-time-base clock synchronization device and method. The device comprises a GPS receiver, a Beidou receiver, a processing module and an alarm module. The device has the advantages that the device simultaneously receives GPS / Beidou time source signals, the time source information is verified through the processing module, the backup time source is called when the main time source fails, short-time normal work is maintained by a built-in high-stability clock when both the main time source and the backup time source fail, and an alarm isgiven out to notify a transformer substation monitoring system; the device and method can achieve electric energy meter double-time-base clock synchronization, the two time sources are the backup time resources for each other, normal work can be kept when satellite signals are interfered, and high operation reliability is achieved.
Description
technical field [0001] The invention relates to the field of time adjustment of electric energy meters, in particular to a novel dual time base time adjustment device and method for electric energy meters. Background technique [0002] At present, there are still many power meter time synchronization modes in substations that are only GPS time synchronization, which is insufficient in safety and reliability. GPS is a satellite navigation system controlled by the US military. Although it is currently open to the world for free, it has nothing to do with my country. The agreement guarantees that it can be used for free indefinitely. When the satellite navigation system does not work normally under certain circumstances or implements signal interference or even shuts down the users in our country during wartime, the blow is devastating to the synchronization network using timing. At the same time, the single time base time synchronization device cannot provide normal time servi...
