Embodiment 1
[0059] This embodiment provides an interactive photothermal environment control system based on personnel positioning and behavior recognition, which is especially suitable for various office buildings and fitness places with large-area glass curtain walls. Such as figure 1 As shown, the system includes: general controller 1, illuminance sensor 2, infrared camera 3, lamps 4, dimming glass device 5, outdoor solar radiation sensor 6 and indoor temperature control device, etc., illuminance sensor 2, infrared camera 3, lamps 4. The dimming glass device 5 , the outdoor solar radiation sensor 6 and the indoor temperature regulating device are all connected to the master controller 1 .
[0060] The outdoor solar radiation sensor 6 is installed on the same outdoor wall as the dimming glass device 5 to detect the outdoor solar radiation value; the illuminance sensors 2 are evenly distributed on the indoor roof to detect the indoor illuminance value; Distributed on the indoor wall to d...
Embodiment 2
[0073] This embodiment provides an interactive photothermal environment control method based on personnel positioning and behavior recognition, which can be applied to the interactive photothermal environment control system based on personnel positioning and behavior recognition in Embodiment 1, such as Figure 8 shown, including the following steps:
[0074] S1, the outdoor solar radiation sensor 6 detects the outdoor solar radiation value in real time and sends it to the master controller 1;
[0075] S2, the master controller 1 judges whether the outdoor weather condition is sunny according to the received outdoor solar radiation value;
[0076] S3. When the outdoor weather condition is sunny, the master controller 1 sends a personnel positioning request to the infrared camera 3 every first time interval;
[0077] S4. After receiving the personnel positioning request, the infrared camera 3 detects the indoor personnel position, obtains the current number of indoor personnel, ...

Abstract
The invention discloses an interactive photothermal environment control system and method based on personnel positioning and behavior recognition, and relates to the technical field of intelligent dimming and advanced regulation of heating, ventilating and air conditioning systems. The system comprises a master controller, an infrared camera, dimming glass devices, an outdoor solar radiation sensor, an indoor temperature adjusting device and the like. The infrared camera is used for detecting indoor personnel positions, personnel behaviors and body surface temperature; the indoor temperature adjusting device is used for pre-estimating the heat dissipating capacity of personnel according to the personnel behaviors and the body surface temperature under the control of the master controller and then adjusting the indoor temperature in advance; and the multiple dimming glass devices are arranged in order to form a whole glass wall surface and mounted on an outdoor wall surface, and each dimming glass device is used for changing the light transmittance according to the outdoor solar radiation value, the solar height angle and the indoor personnel positions under the control of the master controller. The problem of indoor glare caused by outdoor strong light can be solved, indoor heat gain cannot be greatly influenced, and the indoor temperature can be adjusted in advance.
Description
technical field [0001] The invention relates to the technical field of intelligent dimming and advanced adjustment of HVAC systems, in particular to an interactive photothermal environment control system and method based on personnel positioning and behavior recognition. Background technique [0002] The application of large-area glass curtain walls often causes indoor glare problems, especially for people who work near windows. Significant negative impact on personnel comfort. However, the traditional method of blocking the sun’s rays by drawing curtains or automatic blinds will reduce the solar radiation heat entering the room, which is very unfavorable to building energy conservation in winter. [0003] Therefore, the technology of how to adjust the light needs to be born. For example, Chinese patent CN103458555A discloses a partition dimming system, which includes a single-chip microcomputer, and also includes an infrared sensing module connected to the single-chip mic...
