The abnormal data deposited is not lost.
The invention achievement, the defect of abnormal data cannot be saved by compensating for existing equipment, and devise battery pack current
Monitoring, environment temperature monitoring function, avoid monitoring system and in addition increase this functional unit problem.The distant control function of design can
With each electric appliances of remote control.
In practical application, which can be carried out wheel survey formula access by host computer and extract data, meet the system failure, network resistance
When the reasons such as disconnected cannot be generalized machine manipulation or extract data, device leans on itself single-chip microcontroller independent operating, and identifies abnormal (have a power failure
When put point data) after, self-timing test, accumulation save.Communication to be restored or after device is taken back base, can be by host computer one
Secondary property extracts saved abnormal data, and empties storage element and prepare to save data next time.
