Description
Technical field
The present invention relates to a kind of clock restorative procedures based on intelligent power terminal clock battery undervoltage.
Background technique
With the continuous construction of State Grid Corporation of China's " all standing, full acquisition, control in full ", some ends put into operation earliest
End starts some problems occur, such as Clock battery failure.When keeping clock after terminal power-off, thus have one on mainboard
Clock battery gives RTC block power supply, but since battery itself also has self discharge and the later qualification rate problem of battery batch to lead
The cause terminal that put into operation has certain proportion dead battery.If dead battery, terminal will lead to clock after alternating current power-off
It loses, causes that acquisition terminal re-powers the storage of rear data, task reports etc. with the critical function of time correlation all by entanglement, lead
Terminal is caused to be not normally functioning.
Solving the problems, such as this at present, there are mainly two types of methods: first is that hardware replacement, live replacement terminal Clock battery, this method
It needs manufacturer technical staff to rush towards erecting bed, also needs to coordinate Electricity customers scheduled outage, game clock case, also need to open and measure
Lead sealing, scene also need to take electricity using soldering appliance etc., the disadvantage is that labour cost is high, transport cost is high, human cost is high, has a power failure not
Just, electric inconvenience is taken.Another kind is the initiating terminal clock synchronization life in acquisition system main website after artificial discovery terminal clock battery failure
Enable, time adjustment come, this method exist discovery not in time, terminal meter data lose, the problems such as needing manual intervention.
