The preset condition is that the wireless monitoring equipment continuously does not monitor the working signal for a second time; when the wireless monitoring equipment continuously monitors no working signal for a second time in the interval monitoring mode, the wireless monitoring equipment basically can judge that the monitoring object is turned off, so that the wireless monitoring equipment reenters the real-time monitoring mode from the interval monitoring mode, and further closely monitors whether the monitoring object is turned on again or not in real time; the wireless monitoring device records the time of dormancy of the first controller 10 as third time each time and the time of the first controller 10 in a wake-up state as fourth time each time in an interval monitoring mode, and the wireless monitoring device monitors the working signal in real time at intervals and continuously for the fourth time each time in the interval monitoring mode; the first time > the second time > the third time > the fourth time, the second time being greater than the sum of the third time and the fourth time. Further, the first time is greater than sixteen times the sum of the third time and the fourth time and greater than eight times the second time, the third time being greater than eight times the fourth time; the second time is more than twice of the sum of the third time and the fourth time, so that no working signal is monitored after at least complete running of the two-wheeled sleep state and the wake-up state are alternated, a second wireless control signal is sent, and the effect of delayed shutdown of the controlled object is achieved. For example, the first time may be 2 minutes, the second time may be 5 seconds, the third time may be 2 seconds, and the fourth time may be 100 milliseconds. The wireless monitoring device monitors the operating signal each time in the interval monitoring mode for a short time and thus consumes little power in the interval monitoring mode.
The sleep state of the first controller 10 corresponds to sleep in the low power consumption mode. The first controller 10 may wake itself up, and when the wireless monitoring device is in the interval monitoring mode, the first controller 10 in the sleep state wakes itself up by the self-contained watchdog timer to transition from the sleep state to the post-wake state. The first controller 10 in the wake-up state may go to sleep according to a predetermined program setting. The wireless monitoring device is switched into the interval monitoring mode from the real-time monitoring mode to sleep for a third time, then the wireless monitoring device is used for carrying out real-time monitoring on a fourth time after awakening, and the previous round of replacement process is repeated.

When the wireless monitoring device is in the real-time monitoring mode, the remote control switch 12 fails, so that the controlled object cannot be remotely controlled through the remote control switch 12; when the wireless monitoring apparatus is in the interval monitoring mode and the first controller 10 is in the sleep state, the remote control switch 12 is disabled, so that the controlled object cannot be remotely controlled by the remote control switch 12; when the wireless monitoring device is in the interval monitoring mode and the first controller 10 is in the post-wake-up state, the remote control switch 12 is disabled under the condition that the wireless monitoring device monitors the working signal, so that the controlled object cannot be remotely controlled through the remote control switch 12; with this arrangement, the remote switch 12 is effectively prevented from being operated to interfere with the monitoring process.
When the wireless monitoring device is in the interval monitoring mode and the first controller 10 is in the post-wake-up state, the remote control switch 12 is active under the condition that the wireless monitoring device does not monitor the working signal, so that the controlled object can be remotely controlled through the remote control switch 12, therefore, if a user wants to rest for a while and then turns off the monitored object, the controlled object can be immediately turned off in advance through the remote control switch 12 without waiting for expiration of the second time.

In this embodiment, the signal monitoring switch 13 may be a push button switch, and when the signal monitoring switch 13 is active, the signal monitoring switch 13 may be triggered by pressing the signal monitoring switch 13, and when the signal monitoring switch 13 is inactive, the signal monitoring switch 13 is not triggered at all, so how to press the signal monitoring switch 13 is not reacted.

The monitoring object may be a power tool or the like; the wireless monitoring equipment can be arranged at a proper monitoring point to monitor the working signal so as to realize synchronous linkage between the monitoring object and the dust collector 5 based on the working signal, so that the dust collector 5 can timely suck dust, scraps and other garbage generated when the monitoring object works; the wireless monitoring device can be arranged on the monitoring object or on the suction pipe suction head of the dust collector 5 connected with the monitoring object, because when the monitoring object works, the closer to the controlled object, the larger the working noise or vibration of the controlled object can be monitored, and the stronger the corresponding noise or vibration received at the suction pipe suction head position of the dust collector 5. The main control switch 53 is arranged on the shell of the controlled object and is provided with a starting gear, a closing gear and a control gear, when the main control switch 53 is in the starting gear, the dust collector 5 is started, so that the suction motor performs suction work; when the main control switch 53 is in the shutdown gear, the dust collector 5 is turned off, so that the suction motor stops the suction work; when the main control switch 53 is in the control gear, the dust collector 5 can be wirelessly controlled by the wireless monitoring device.
