Single chip processing module was waken up from park mode by the predetermined time, and networking is connected to main frame, sends and reads life
The measurement result of level meter is read in order, according to communications protocol, data is changed and packs, and regularly passes through wireless transport module
Send data to monitor terminal.After the completion of transmission process, single chip processing module control system modules enter park mode,
Reduce power consumption.Particularly, for measurement frequency than situation faster, that is, time of measuring interval is less than ultrasonic material level meter initialization
The process deadline, level meter will always be in working condition, only single chip processing module and wireless module and enters park mode.
Those of ordinary skill in the art it should be appreciated that above embodiment be intended merely to illustrate the present invention,
And it is not used as limitation of the invention, as long as in the spirit of the present invention, to the change of above example, change
