Problems solved by technology

[0008] In the case of using such prior art to automatically control the lighting fixtures arranged on the ceiling according to whether there are people in the lighting area of ​​the lighting fixtures, there has been the following problem in the past: if only the detection position and the lighting area of ​​the detected person are comparison, smooth lighting control cannot be achieved

no. 1 Embodiment approach

[0033] First, refer to figure 1 , the lighting control device 10 according to the first embodiment of the present invention will be described. figure 1 It is a block diagram showing the configuration of the lighting control device.

[0034] The lighting control device 10 is generally composed of an information processing device such as a server device and an industrial controller, and is a device that controls the lighting fixture Q installed in the R in response to the human detection result related to the target space R obtained by the human detection system 20 .

[0035] The human detection system 20 utilizes a plurality of infrared sensors SP composed of thermopile array sensors installed on the ceiling or wall of the target space R to detect thermal images (thermal maps) in R, and transmits the information from each person via the communication line L2. A general system that detects a person U present in R by searching a person area showing the surface temperature of a ...

no. 2 Embodiment approach

[0085] Next, the lighting control device 10 according to the second embodiment of the present invention will be described.

[0086] Generally speaking, there will be errors in the results of human detection, and there are two types of errors. That is, the error "some people think no one" and the error "no one thinks someone". In most cases, which tendency to set can be adjusted by adjusting parameters of the human detection method, for example, parameters related to the sensitivity of human detection determination.

[0087] The so-called "low-sensitivity human detection" is a human detection that is adjusted to slightly increase the error of "someone thinks there is no one". When it's time to adjust, in turn, the "no one thinks someone" error is reduced. On the other hand, the so-called "high-sensitivity human detection" is adjusted to slightly increase the error of "no one thinks there is someone". When it's time to adjust, in turn, the "someone thinks nobody" error is red...

Abstract

The lighting control method and device of the present invention can efficiently and automatically control lighting fixtures without unnecessary monitoring time according to human detection results. The lighting control part (16) compares the position of the lighting area (S) and the position of the buffer area (K) with the person detection position, and lights the lighting fixture (Q) when there is a person in the lighting area (S). Turn off the lighting fixture (Q) when there is no one (U) in the area and the buffer area (K), and turn off the lighting fixture (Q) when there is no one (U) in the lighting area (S) and there are people (U) in the buffer area (K) The previous control state of the lighting fixture (Q) is maintained.

Description

technical field [0001] The invention relates to an illumination control method and device. Background technique [0002] In the past, it has been proposed to search for a human area showing the surface temperature of a person from a thermal image (thermal map) in the target space detected by a plurality of infrared sensors installed on the ceiling or wall of the target space, thereby detecting the existence of the target. Human detection technology for occupants in a space (for example, refer to Patent Document 1, etc.). Thereby, it is possible to realize automatic control of the environment of the target space, such as controlling a comfortable air-conditioned environment only in a space with occupants, and stopping air conditioning and lighting in a space without occupants. [0003] When a thermopile array sensor, which is one of the infrared sensors, is installed on the ceiling to measure the temperature distribution on the floor, a person who is a heating element is det...
