Because the person on duty can monitor the condition in the house of the owner directly through the system, in order to ensure the privacy of the life of the owner, the anti-theft monitoring of the system adopts the human body sensor to monitor whether a person in the house rushes into the house privately, so that the indoor monitoring can be realized when the owner goes out, and the privacy of the owner can also be ensured.

When any monitoring module of the carbon monoxide sensor, the flame sensor, the human body sensor and the pressure sensor is triggered, the system can send a monitoring signal to the first single chip microcomputer, the first single chip microcomputer sends the monitoring signal to the wireless receiving module through the wireless transmitting module and finally sends the monitoring signal to the second single chip microcomputer, the second single chip microcomputer sends information pre-stored in the second single chip microcomputer to the display to be displayed according to the monitoring signal, and meanwhile the alarm module is started.

Specifically, if a carbon monoxide sensor in the house of a certain owner is triggered, namely the condition of gas leakage occurs indoors, the carbon monoxide sensor sends out a monitoring signal, the monitoring signal is transmitted to a second single chip microcomputer through the transmission of a first single chip microcomputer, a wireless transmitting module and a wireless receiving module, the second single chip microcomputer sends related content of gas leakage in the house of the owner to a display according to the monitoring signal, and an alarm module is started simultaneously to remind a person on duty to confirm timely. If the flame sensor in the house of a certain owner is triggered, namely the condition of open fire appears in the house, the flame sensor sends out a monitoring signal, the monitoring signal is transmitted to the second single chip microcomputer through the first single chip microcomputer, the wireless transmitting module and the wireless receiving module, the second single chip microcomputer sends related content with fire hazard in the house of the owner to the display according to the monitoring signal, and meanwhile, the alarm module is started to remind a person on duty to confirm in time.
