Problems solved by technology
[0003] At present, existing human body sensing devices and indoor units either use the half-duplex communication protocol H-NET communication method, or use the traditional Universal Asynchronous Receiver / Transmitter (UART for short) communication method. The sensing devices are not compatible with the two communication methods of H-NET and UART, resulting in limited use space of human body sensing devices

Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] Generally, the communication methods of air-conditioning indoor units mainly include H-NET and UART; among them, the H-NET communication method is a communication form of homebus technology, which has a long communication distance and good stability, and this method Support group control, considering the fact that an independent human body sensing device may control multiple indoor units in actual use, the H-NET method just solves this technical difficul...

The embodiment of the present invention is applied to an air conditioning system.
Description
technical field [0001] Embodiments of the present invention relate to the field of household appliance manufacturing, in particular to a human body sensing device and an air conditioning system. Background technique [0002] With the improvement of people's living standards, air conditioners have been widely used in various occasions. The human-sensing function of air-conditioning units has become a trend in product development. After enabling this function, the air-conditioner can realize the function of following the wind with people. For example, the air-conditioner turns on heating in winter When functioning, if the human body sensor detects that there are more than two people in the room, the set temperature of the air conditioner will be automatically lowered by 1°C. In summer, if only one person is detected in the room, the set temperature of the air conditioner will be lowered. It will automatically increase by 1°C, which not only saves power, but also allows users t...
