Problems solved by technology

[0002] In the intelligent construction of hotel rooms, it is necessary to install human body infrared sensors to realize the function of human body movement detection. At present, human body infrared sensors on the market are mainly based on external power supply and wired communication. When the external power supply fails, the human body infrared movement sensor will lose its function. In the hotel room, the controlled power supply is uniformly controlled by the host. When the host does not take power, the controlled power supply is disconnected, and the electrical equipment in the room has no power supply. The traditional infrared sensor cannot work normally, and the memory in the room Difficult wiring, high complexity of power lines and communication lines, and high hotel renovation costs. In the prior art, there is also a separate uninterrupted power line for infrared sensors to keep detecting and sending status information at all times, but this is costly and expensive. Greatly increased energy consumption, not conducive to energy saving

Embodiment Construction

[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0028] Such as figure 1 As shown, this embodiment provides the application of the wireless low-power infrared sensor and its control method described in the present invention in a wirelessly controlled hotel intelligent system. In a guest room unit, only the RCU host, infrared sensor and door sensor are required. module. Among them, such as image 3 As shown, the infrared sensor includes an infrared detector, an infrared signal processing chip and an infrared wireless communication module connected in sequence. The controlled power supply is connected to the infrared detector, the infrared signal processing chip and the infrared wireless communication module through a power conversion circuit and supplies power to it. The conversion circuit converts the AC220V mains power from the contro...

Abstract

The invention provides a wireless infrared sensor with low power consumption as well as a control method and application thereof. By adopting a wireless communication design, the human infrared motion sensor is free from wiring and convenient to install; meanwhile, by adopting a double-channel power supply mode, the sensor with a rechargeable battery can work normally when external power supply stops, thereby ensuring normal information acquisition of hotel rooms; by designing a normal sleep mode, when human motion is sensed by infrared, the sensor awakens an MCU (Micro Control Unit), wirelessly sends infrared detection information and then enters dormancy, thereby saving energy and prolonging the service life of the battery.
