In addition, the operation process of the automatic power-saving switch of the television with the infrared human body induction also comprises the following steps:
firstly, after the television 7 enters a standby state, the main control unit 3 starts timing when transmitting an 'action' signal to the relay signal terminal 41 of the relay module 4 through the I/O interface 33, and the infrared sensor 1 keeps running during the timing process; secondly, when the detection data collected by the infrared sensor 1 represents that a human body exists in a target area in front of the television 7, the sensor signal end 11 of the infrared sensor 1 continuously transmits a signal for representing that the human body exists to the I/O interface 33 of the main control unit 3, and the timing is stopped; thirdly, the main control unit 3 transmits a signal for representing 'closing' to the relay module 4; fourthly, when the relay signal end 41 of the relay module 4 receives the signal for representing "close", the controlled end 43 of the relay module 4 is controlled to be switched from a normally open mode to a normally closed mode, and the television 7 is powered on and enters a working state; when the timed duration reaches the set time, the relay signal end 41 of the relay module 4 receives the signal for representing "close" transmitted by the main control unit 3, and then controls the controlled end 43 of the relay module 4 to switch from the normally open mode to the normally closed mode, and the television 7 is powered on and enters a working state.
