[0022] In this embodiment, the sensing probe uses a D203S pyroelectric infrared sensor, and the signal processing uses a dedicated chip BISS0001. First, the D203S detects the human infrared signal, and then the BISS0001 amplifies the signal and compares the levels. Finally, the result is input to the mixing console through the P1.6 pin and an interrupt is requested through the P3.3 pin. In addition, multiple human infrared signal detection circuits can be set up through the NAND gate chip 74LS30, thereby dividing the indoor space into multiple detection areas to achieve regional control of the lighting equipment. The temperature sensor uses the DS18B20 temperature sensor, which features the ability to connect multiple DS18B20s in parallel to two or three lines. The mixing console only needs one port to communicate with many DS18B20s, saving a lot of wiring and logic circuits. Therefore, it is suitable for long-distance multi-point temperature measurement. The sensor can directly convert the temperature signal into a digital signal, input it to the mixing console through the P1.5 pin, and request an interrupt through the P3.2 pin. The number of DS18B20 sensors can be set differently according to the room layout through the NAND gate chip 74LS30. The data acquisition circuit uses a CdS (cadmium sulfide) photoresistor GM3516 as the sensor. When a voltage is applied across the photoresistor and it is exposed to light of an appropriate wavelength, the resistance of the photoresistor increases as the light intensity decreases, and its voltage drop V... LThe voltage increases accordingly, thus achieving photoelectric conversion, and is sent to comparator LM393 and compared with the set value V. REF The comparison is performed, the result is sent to the mixing console's P1.7 pin, and an interrupt is requested via the P3.2 pin. When V... REF <V L When V indicates that the actual light intensity is low, the lighting equipment can be turned on. REF >V L When the actual light intensity is high, it means that the lighting equipment does not need to be turned on or needs to be turned off. The infrared detection circuit at the entrance uses an infrared LED (IRLED) and an infrared detector CHQ1838D as the main detection components. When the circuit is working, the mixing console programs the IRLED to emit infrared light at a frequency of 38.5kHz, with a wavelength of 980nm. The infrared detector has a built-in optical filter to filter out any visible light with a wavelength of 980nm. The detector also has a built-in electronic filter to make the detector only look for infrared light sources that flash 38.5k times per second, thereby preventing interference from other light sources (such as indoor lights or sunlight) to the infrared detection.
