As shown in fig. 3, the infrared remote control module includes an infrared transmitter and an infrared receiver, and the infrared transmitter chip transmitter adopts a PPM coding method. When the transmitter button is pressed, a set of 108ms coded pulses will be sent. The preamble, 8 bit user code reverse code, 8 bit operation code and 8 bit operation code reverse code, constitute the pulse code on the remote controller. Each remote controller can control only one operation of the devices by verifying the user code, and each remote controller can control only one operation, so that disturbance among a plurality of devices can be effectively prevented. After the code reversal is encoded, the correctness of the code reversal can be verified by the received code, so that the fault is prevented, and the reliability of the system is improved. The initial part of the remote control code is a preamble, and the low level 9ms and the high rate 4.5ms constitute the preamble as a preparation impulse for receiving data. Binary "0" is expressed as a pulse width of 0.56ms and a period of 1.12 ms; a binary "1" is represented as a pulse width of 1.68ms and a period twice that of a binary "0". If the button is pressed for more than 108 milliseconds and is not released, the start code (9ms) and end code (2.5ms) constitute the next transmitted code.

As shown in fig. 2 and 4, the single chip receives a receiving line of an infrared receiver, the receiving line HW of the infrared receiver is connected to the external interrupt INT1 pin, and the edge triggered mode is the interrupt mode. The interrupt interval time is calculated using timer 0 to separate the preamble, binary codes "1" and "0". The 8-bit operation code is drawn and displayed on the digital tube.

In the temperature control module, a relay is used as a switch, and a light-emitting diode is used as an on signal indication. As shown in fig. 5, the temperature control module is connected to the 5 pins of the single chip microcomputer through a connection point L, the L is connected to the base of a 9012PNP triode in the relay loop, the loop on-off control is performed through the high and low level of the signal output of the single chip microcomputer, when the loop is closed, the warming relay K1 acts, the light emitting diode D1 is used as a warming indicator light to light up for indication, and the warming action is started. And the temperature range set by the user is stored in the singlechip, and when the system receives a temperature signal sent by the temperature sensor DS18B20, once the temperature reaches the limit temperature, the temperature-raising relay K1 is powered off and stops acting, so that the stable control of the temperature is realized.
