Under pattern, charge the battery;In a battery supply mode if it find that sensor is in the state that falls off, it is to supervise to illustrate machine not
Under shield pattern, it is not necessary that the electricity in power consumption pond is cut under mould to AC power supply pattern, while can be charged the battery.
Step 4: being switched to AC power supply pattern, the operation of step 1 is repeated.By parsing the data of CSM modules, sentence
The state of disconnected module, repeats monitoring work.
Step 5: if judging to show that the powering mode of master control system is not battery powered mode, master control in step 1
System finds out the mode bit of CSM modules, and judges whether mode bit is false signal alarm.False signal is non-true signal value,
It is that CSM modules parse the value of coming.
Step 6: carrying out step 8 if when mode bit is false signal alarm;It alerts, then reads if not false signal
Signal quality index;And compared that (signal quality index is parsed by the data of CSM modules with last time signal quality index
Come), judge whether performance figure is drop mode, if it find that being drop mode, then carries out step 7;If not decline
Pattern then carries out step 8.
Step 7: in the case that signal quality index is in drop mode, judge whether fall time persistently has 3 minutes,
If it is declining always, then it is judged as being disturbed, is switched to step 8;If not continuing 3 minutes, return to step one, weight
It is re-reading to take datamation.
