The monitoring device (obviously, a wireless transceiver device matched with the wireless transceiver 75 at the controller end is arranged on the monitoring device) sends a control command to the controller 70, and when the controller 70 receives the control command, a high level signal or a low level signal is generated to control the electronic switch 71 to be switched on or off, so that the power supply 60 supplies power or does not supply power to the ultrasonic generator 40 and the fan 50, and the purpose of remotely controlling the automatic atomization disinfection system of the closed space and the elevator room is achieved. The manner in which the controller 70 receives the control instruction and converts the control instruction into high-level output is a conventional means of existing remote control, and may be similar to a remote controller of an air conditioner, a television, or the like to control the on-off function of the air conditioner and the television, or similar to a manner in which a remote controller (e.g., a mobile phone, or the like) in an intelligent home controls the remote controller through a cloud port.

Here, the conventional comparison function of the controller 70 is used, and of course, the controller 70 may be replaced by a discrete component, such as a comparator, in which the power voltage detected by the sampling circuit 72 is input to the inverting input terminal of the comparator, the non-inverting input terminal of the comparator is input with the preset voltage threshold, and the output terminal of the comparator is connected to the near-end short-circuit reminder 73 (or to the enable terminal of the electronic switch between the power supplies of the near-end short-circuit reminder and the near-end short-circuit reminder).

In addition, if the monitoring equipment is provided with a far-end power shortage reminder; the controller 70 may also send a power shortage reminding instruction to the monitoring device through the wireless transceiver 75, and the monitoring device outputs a high level to the far-end power shortage reminder to control the far-end power shortage reminder to send a power shortage reminder. Here, the power shortage warning instruction sent by the controller 70 is formed by compiling in advance, when the collected voltage of the sampling circuit 72 is smaller than the preset voltage threshold, the controller 70 sends the power shortage warning instruction (for example, 0010) compiled in advance to the monitoring device, and the monitoring device receives the coding instruction of 0010, and then outputs a high level to the far-end power shortage reminder.

The conventional comparison function of the controller 70 is used here, but of course, the controller 70 may also be replaced by a discrete component, such as a comparator, in which the liquid level information (generally, a voltage value) detected by the liquid level sensor 22 is input to an inverting input terminal of the comparator, a non-inverting input terminal of the comparator is input with a preset liquid level threshold, and an output terminal of the comparator is connected to the near-end liquid filling reminder 74 (or to an enable terminal of an electronic switch between the power supplies of the near-end liquid filling reminder and the near-end liquid filling reminder).

In addition, if the monitoring equipment is provided with a remote liquid adding reminder; the controller 70 can also send a liquid adding reminding instruction to the monitoring equipment through the wireless transceiver 75, and the monitoring equipment outputs a high level to the far-end liquid adding reminder to control the far-end liquid adding reminder to send a liquid adding reminder. The liquid adding reminding instruction sent by the controller 70 is compiled in advance, when the collected voltage of the sampling circuit 72 is smaller than the preset voltage threshold, the controller 70 sends the liquid adding reminding instruction (e.g. 0011) compiled in advance to the monitoring device, and the monitoring device outputs a high level to the remote liquid adding reminder when receiving the coded instruction of 0011.

The output of the liquid concentration sensor 33 is connected to a third input of the controller 70, and a third output of the controller 70 is connected to the solenoid valve.

When the controller 70 receives that the liquid concentration information collected by the liquid concentration sensor 33 is smaller than the preset concentration threshold, a high level signal is sent to the electromagnetic valve, and the electromagnetic valve is closed, so that the disinfectant is injected into the atomizing chamber 30.

Here, the conventional comparison function of the controller 70 is used, and of course, the controller 70 may be replaced by a discrete component, such as a comparator, in which the liquid concentration information (generally, a voltage value) detected by the liquid concentration sensor 33 is input to an inverting input terminal of the comparator, a predetermined concentration threshold value is input to a non-inverting input terminal of the comparator, and an output terminal of the comparator is connected to the solenoid valve (or an enable terminal of an electronic switch connected between the solenoid valve and a power supply of the solenoid valve).
