Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. the

Fig. 1 is a schematic composition diagram of an intelligent lighting system according to an embodiment of the present invention. As shown in Figure 1, an intelligent lighting system includes: a plurality of lighting devices 10; a plurality of sensing devices 11 for detecting signals of objects in the area; an analysis device 12 for obtaining the detected signal of each sensing device Then analyze the position and direction of movement of the object; the control device 13, based on the analyzed position and direction of the object, turns on the lighting device located in front of the object in the moving direction of the object, and turns off the lighting device behind the object. the

Through this embodiment, it can be clearly seen that according to the movement of the object, only the lighting device in front of the moving direction of the object is turned on, while the lighting devices behind it are all turned off, so the energy saving efficiency can be greatly improved and the energy consumption can be reduced. waste. the

Preferably, the sensing device has a certain detection area, and the interval between multiple sensing devices is smaller than the detection area of the single sensing device, that is, the detection areas of adjacent sensing devices have a certain overlap. the

Specifically, for the sensing device, it has a certain detection area. In order to make the detection area of the sensing device set cover all the detected areas without leaving a detection blind area, when the sensing device is set, Usually, the detection areas of two adjacent sensing devices are set to have a certain overlap. the

Fig. 2 is a schematic layout diagram of the sensing device of the embodiment of the present invention. As shown in Figure 2, the detection areas of the sensing devices A, B, C, and D all have a certain coverage (m), so that it can be ensured that there is no blind spot in the detection of the sensing device, that is, the object can be detected at any position. detected by the set sensor. the

Preferably, the analysis device includes: a first judging unit, configured to judge that a second sensing device adjacent to the first sensing device is within the detection area when the first sensing device detects a signal of an object in the detection area Whether the signal of the object is detected; the second judging unit is used to repeatedly judge the second sensing device when the second sensing device detects the signal of the object in the detection area, until it is judged that the second sensing device is in When the signal of the object cannot be detected in the detection area, it is judged whether the first sensing device can still detect the signal of the object in the detection area; the determination unit is used to detect the object when the first sensing device can still detect the object in the detection area When the signal of the object is determined, it is determined that the object is moving from the second sensing device to the direction of the first sensing device; Movement in the direction of the second sensor unit. the

Specifically, for each sensing device, it is in a non-stop detection state, as long as an object appears in the area covered by the detection area of the sensing device, the object will be detected by the nearby sensing devices , through the real-time detection of the adjacent sensing device, the specific movement direction of the object can be judged by the analysis device. the

In order to further confirm the direction of the movement of the person, the detection state of the sensing device A will be continuously tracked at this time, that is, it is repeatedly judged whether the sensing device A can detect the infrared signal emitted by the human body, until it is judged that the sensing device A receives When the infrared signal sent by the human body is not received, it is judged whether the sensing device B can still receive the infrared signal sent by the human body. the

As shown in Figure 4, if the sensing device B can still receive the infrared signal sent by the human body at this time, it can be determined that the person is moving from point b to point c, that is, the human body is moving from sensing device B to sensing device C. and if the sensing device B also cannot receive the infrared signal sent by the human body at this time, it can be determined that the person moves from point b to point c', that is, the human body is moving from the sensing device B to the direction of the sensing device A, As shown in Figure 5. the

Referring to FIG. 2 , for example, the time can be counted from the time when the sensing device B receives the signal from the object until the sensing device A fails to receive the infrared signal from the human body. The coincidence distance between the two sensing devices A and B is known, so the speed of the moving object can be calculated according to the distance and the timing time. According to the speed, the number of lighting devices that need to be turned on in front of the moving object can be further set. When the moving speed of the object is high, more lighting devices can be turned on in front of the moving object; on the contrary, when the moving speed of the moving object is low, some lighting devices can be properly turned on less. the
