Embodiment 1

[0036] When someone presses the doorbell button, the key input unit receives the information and transmits the information to the main control unit, and the main control unit transmits the "detection" information to the human body detection units distributed in each room, which are installed in each room The human body detection unit detects whether there is a person in the room; if a person is detected, this information is fed back to the main control unit; the main control unit sends the "measurement" information to the space detection unit to measure the size of the room. First, the space detection unit transmits ultrasonic waves through the first ultrasonic transmitter and starts timing at the same time. When the first ultrasonic receiver receives the reflected wave, it stops timing. The time difference between the transmitted and received echoes recorded by the timer can be calculated. Long, then the second ultrasonic transmitter emits ultrasonic waves and starts timing at...
