[0037] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0038] Figures 1 to 5 A preferred embodiment of the presence control device of the present invention is shown.

[0039] The presence-type control device can be applied to a room or space where a single person is present. The entrance and exit of the space can be set, and it can judge whether there is someone in the space. It can also detect different directions and different areas, and control various equipment when there is someone or no one in the room or space, thereby playing a role in energy saving and environmental protection. The presence-type control device has high recognition, a wide range of application, and a high level of intelligence.

[0040] like Figure 1 and Figure 2 As shown, the presence control device includes a mounting bracket 10, a first group of sensors and a second group of sensors separately arranged on the mounting bracket 10. The mounting bracket 10 can be used to install the first group of sensors and the second group of sensors, and plays a role in protecting and supporting the first group of sensors and the second group of sensors. The first group of sensors and the second group of sensors can cooperate with each other, thereby improving the recognition accuracy of the presence control device. The presence control device also includes a control device arranged in the mounting bracket 10 and connected to the first group of sensors and the second group of sensors to receive signals from the first group of sensors and the second group of sensors to control switches of various devices in the room. When the first group of sensors and the second group of sensors sense that there are people in the space, the devices in the space, such as air conditioners, electric lights, etc., are turned on, and when it is sensed that there are no people in the space, the devices in the space are turned off to achieve energy saving and environmental protection.

[0041] The mounting bracket 10 can be arranged at the entrance and exit of the space. In this embodiment, the mounting bracket 10 includes a first shell 11 and a second shell 12 detachably connected to the first shell 11. The first shell 11 and the second shell 12 can be connected by snaps, screws, etc. In some other embodiments, the first shell 11 and the second shell 12 can also be integrally formed. The first shell 11 can be used to install the first group of sensors, and the second shell 12 can be used to install the second group of sensors, so that the first group of sensors and the second group of sensors sense different areas.

[0042] The first housing 11 can be made of wood, plastic, metal or other materials, and can be semi-cylindrical. In some other embodiments, the shape of the first housing 11 is not limited to semi-cylindrical. The mounting bracket 10 includes a first sensing surface 111; specifically, the first sensing surface 111 is disposed on the first housing 11, and a surface of the first housing 11 facing away from the first sensing surface 111 is a connection surface connected to the second housing 12.

[0043] In this embodiment, the first sensing surface 111 is a curved surface of the first shell 11 , which can be disposed toward the interior of the space to determine whether there is a person in the space.

[0044] The first sensing surface 111 is provided with a first group of mounting holes 112 that are adapted to the size of the optical lens of the first group of sensors; the first group of mounting holes 112 is arranged in the first housing 11, and the first group of mounting holes 112 includes a first mounting hole 1121 and a second mounting hole 1122 that are arranged side by side on the first sensing surface 111. In this embodiment, the first mounting hole 1121 and the second mounting hole 1122 are arranged side by side in the longitudinal direction. The apertures of the first mounting hole 1121 and the second mounting hole 1122 are substantially equal to the diameter of the optical lens of the first group of sensors. In some other embodiments, the number of the first group of mounting holes 112 is not limited to two, and it can be one, three, four or more.

[0045] The first group of sensors is mounted on the mounting bracket 10 and is arranged corresponding to the first sensing surface 111 to form a first sensing area. Specifically, the first group of sensors is mounted in the first group of mounting holes 112, and the number of the first group of sensors is consistent with the number of the first group of mounting holes 112; the first sensing area can be inside the space.

[0046] In this embodiment, the first group of sensors includes a first infrared sensor and a second infrared sensor respectively arranged in the first mounting hole 1121 and the second mounting hole 1122 to identify whether there is a human body in the room. The first infrared sensor and the second infrared sensor can also be infrared pyroelectric sensors, which can determine whether there is a human body in the space and transmit the information of the human body to the control device. The light-transmitting surface size of the optical lens of the first infrared sensor is substantially equal to the size of the first mounting hole 1121; then the cross section of the first mounting hole 1121 is the light-transmitting surface of the first infrared sensor, and the light-transmitting surface size of the optical lens of the second infrared sensor is substantially equal to the size of the second mounting hole 1122, then the cross section of the second mounting hole 1122 is the light-transmitting surface of the second infrared sensor.

[0047] like Figures 3 to 5As shown, the second shell 12 can be made of wood, plastic, metal and other materials. It includes a first body 1211 and a second body 1212 detachably connected to the first body 1211. The first body 1211 and the second body 1212 are detachably connected to facilitate the removal or installation of the second group of sensors. The mounting bracket 10 includes a second sensing surface 1213 that is set at a set angle to the first sensing surface 111. Specifically, the second sensing surface 1213 is arranged on the side wall of the second shell 12, and the second sensing surface 1213 and the first sensing surface 111 are located on different planes, so that the sensing areas of the first group of sensors and the second group of sensors are different.

[0048] The second sensing surface 1213 is provided with a light limiting groove 122, the width of which is smaller than the sensing angle of the second group of sensors; and the depth of which is greater than its width, which can limit the sensing angle of the second group of sensors and reduce the monitoring area of ​​the second group of sensors. In this embodiment, the light limiting groove 122 is in the shape of a rectangular parallelepiped. Specifically, the light limiting groove 122 is provided on the first body 1211 and extends from the long side of the first body 1211 to the other long side of the first body 1211.

[0049] The second sensing surface 1213 is provided with a second group of mounting holes 123 that are adapted to the size of the optical lens of the second group of sensors and are connected to the light limiting groove 122; specifically, the second group of mounting holes 123 is arranged in the second shell 12, and further, the second group of mounting holes 123 is arranged on the second body 1212. The first group of mounting holes 123 includes a third mounting hole 1231 and a fourth mounting hole 1232 that are arranged side by side on the second sensing surface 1213. The third mounting hole 1231 and the fourth mounting hole 1232 are arranged side by side in the longitudinal direction. The apertures of the third mounting hole 1231 and the fourth mounting hole 1232 are substantially equal to the diameter of the optical lens of the first group of sensors. In some other embodiments, the number of the second group of mounting holes 123 is not limited to two, and it can be one, three, four or more.

[0050] A connecting device is provided between the first body 1211 and the second body 1212; the connecting device includes a clamping position 1241 provided on the side of the first body 1211 and a clamping bone 1242 provided on the side of the second body 1212 and corresponding to the clamping position 1241. In this embodiment, the number of the clamping position 1241 can be two, respectively distributed on two long sides of the first body 1211 that are relatively arranged. Correspondingly, the number of the clamping bones is also two, and they are respectively provided on two long sides of the second body 1212 that are relatively arranged. In some other embodiments, the clamping position 1241 can be provided on the side of the second body 1212, and the clamping bone 1242 can be provided on the first body 1211.

[0051] For example Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, a fixing device 125 for fixing the first body 1211 and the second body 1212 is further provided between the first body 1211 and the second body 1212. The fixing device includes a slot 1251 provided on the first body 1211 and a buckle 1252 provided on the second body 1212. By inserting the buckle 1252 into the slot 1251, the first body 1211 and the second body 1212 can be fixed.

[0052] The second group of sensors is mounted on the mounting bracket 10, and is arranged corresponding to the light limiting groove 122 to form a second sensing area staggered from the first sensing area. Specifically, the second group of sensors is mounted in the second group of mounting holes, and the light of the second group of sensors can be transmitted through the second group of mounting holes. Due to the limitation of the light limiting groove 122, the sensing angle of the first group of sensors is greater than the sensing angle of the second group of sensors; and the monitoring area of ​​the first sensing area is greater than the monitoring area of ​​the second sensing area. In this embodiment, the first sensing area can monitor the indoor space, and the monitoring range of the second sensing area is limited to the vicinity of the entrance and exit.

[0053] Further, the second group of sensors includes a third infrared sensor and a fourth infrared sensor respectively arranged in the third mounting hole 1231 and the fourth mounting hole 1232 to identify whether there is a person entering or exiting the entrance. The third infrared sensor and the fourth infrared sensor can also be infrared pyroelectric sensors, which can determine whether there is a person entering or exiting the entrance and transmit the information of the person entering or exiting to the control device. The light-transmitting surface size of the optical lens of the third infrared sensor is substantially equal to the size of the third mounting hole 1231; then the cross section of the third mounting hole 1231 is the light-transmitting surface of the third infrared sensor, and due to the limitation of the light-limiting groove 122, the actual light-transmitting surface is smaller than the cross section of the third mounting hole 1231. The light-transmitting surface size of the optical lens of the fourth infrared sensor is substantially equal to the size of the fourth mounting hole 1232; then the cross section of the fourth mounting hole 1232 is the light-transmitting surface of the fourth infrared sensor, and due to the limitation of the light-limiting groove 122, the actual light-transmitting surface is smaller than the cross section of the fourth mounting hole 1232.

[0054] Taking the presence control device set at the entrance and exit of a room where a single person is present as an example, the presence control device implements a method of intelligent control: when a person enters a room, first, when the person arrives at the entrance and exit, the third infrared sensor and / or the fourth infrared sensor first receives an infrared signal indicating the presence of the person, and sends the signal to the control device; second, when the person enters the room, the first infrared sensor and / or the second infrared sensor senses the presence of the person in the space, and sends the infrared signal to the control device, and the control device determines that someone has entered the space according to the sequence of the two infrared signals received, and then controls the corresponding equipment in the room to turn on. When a person leaves the room, first, when the person walks toward the entrance and exit, the first infrared sensor and / or the second infrared sensor first receives a signal indicating the presence of the person, and sends the infrared signal to the control device; second, when the person arrives at the entrance and exit, the third infrared sensor and the fourth infrared sensor receive infrared signals indicating the presence of the person, and send the infrared signal to the control device; the control device determines that someone has left the space according to the sequence of the received infrared signals, and then controls the corresponding equipment in the room to turn off.

[0055] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
