Pet cats, etc.

The spatial zone detecting device 10 includes a main board, a plurality of detectors disposed on the main board and having different detection ranges. The motherboard can be used to install a plurality of detectors to support and fix the plurality of detectors, and also to drive. The plurality of detectors can detect the space 100 in real time from different angles and different regions, thereby improving detection accuracy and accuracy. The space zone detecting device 10 further includes a mounting bracket to which the main board is fixed. The mounting bracket can support and fix the space partition detecting device 10.

The mounting bracket may be disposed at any position within the space 100, for example, may be disposed at the entrance and exit of the space 100, or may be disposed at the top of the space 100 and placed at the middle. The mounting bracket can be made of plastic, metal or the like, and can be cylindrical, hemispherical or the like. In other embodiments, the switch of the mounting bracket is not limited to a cylindrical shape or a hemispherical shape.

Each of the detectors includes a sensing unit and a focusing unit that is disposed on the periphery of the sensing unit to collect the sensing signals into the sensing direction of the sensing unit, so that each detector forms an independent direction along its sensing direction. The line sensing area, which in turn divides the space 100 into a plurality of independent detection areas.

Specifically, each sensing unit includes a substrate, a sensing component disposed on the substrate, and a cap disposed on the substrate and disposed outside the sensing component, wherein the sensing cap is disposed on the cap corresponding to the sensing component. Sensing window. The size of the sensing window forms a sensing surface of the sensing element that can be disposed toward the interior of the space 100 for detecting an object within the space 100, such as for detecting the presence of a person within the space 100.

Alternatively, the sensing unit may be an infrared pyroelectric sensor. In other embodiments, the sensing unit is not limited to an infrared pyroelectric sensor, and may be other presence sensors. The infrared pyroelectric sensor is simple to detect, and when a human body passes through the sensing direction, a sensing signal can be generated, thereby detecting the presence of the human body. Moreover, the infrared pyroelectric sensor requires less data to be processed, the data processing operation is simple, and the price is low, thereby reducing the material cost of the entire space partition detecting device 10, simplifying the data operation processing, and improving the efficiency.

The sensing unit is provided with a pin, the pin extends out of the substrate, and the pin is connected to the motherboard. The pin includes three pins, which are a positive pin, a negative pin, and a signal pin. Taking the human body as an example, when the human body enters the sensing area of the sensing unit, the sensing unit can receive the infrared signal of the human body, and generate a sensing signal according to the infrared signal, and the sensing signal is output by the signal pin. Further, the probe can be fixed on the main board by the pin. Generally, the pin can be soldered to the main board to fix the detector on the main board. In some other embodiments, the sensing unit can also be fixed on the main board by means of a patch.

a focusing unit, disposed at a periphery of the sensing unit to focus the sensing signal to a sensing direction of the sensing unit, so that each detector forms an independent direction along its sensing direction (ie, the sensing direction of the sensing unit) The sensing area further divides the space 100 into a plurality of independent detection areas. Alternatively, the focusing unit may be a Fresnel lens, and the Fresnel lens may be in the shape of a cylinder, a truncated cone or a sphere. In other embodiments, the Fresnel lens is not limited to a cylindrical shape, a truncated cone shape, or a spherical shape. .

Further, in various embodiments of the present invention, the Fresnel lens in each detector adopts different angles, that is, the space partition detecting device 10 of the embodiment of the present invention integrates multiple detectors, and each detector Fresnel lenses of different angles are used to divide the space 100 into a plurality of independent detection areas. As shown in FIG. 1, FIG. 1 is a projection view of a separate detection area formed by each detector along its sensing direction, wherein each strip in FIG. 1 corresponds to sensing of one detector. The area, when the human body enters the space 100, can be detected by the detector if it passes through the sensing area of any one of the detectors.

The motherboard has a plurality of jacks, and the pins are fixed in the jacks, so that the detectors composed of the sensing unit and the focusing unit are fixed to the main board through the pins. Optionally, the motherboard can be a PCB board.

Further, the sensing regions formed by each of the detectors along the sensing direction are independent and linear. As can be seen from FIG. 1, the line sensing regions formed by the plurality of detectors are projected onto the plane. That is, the longitudinal detection area and the lateral detection area are formed, and the adjacent longitudinal detection area and the adjacent lateral detection area are non-sensing areas, and the longitudinal detection area and the lateral detection area are vertically and horizontally distributed. Further, as shown in FIG. 1, the longitudinal detection area and the lateral detection area are vertically and horizontally arranged to form a plurality of non-sensing areas, and the area of each of the non-sensing areas on the plane is smaller than the area of the object to be tested, in other words, formed. Each of the non-sensing areas is spatially smaller than the body shape of the object to be tested. That is, by using a plurality of detectors having different detection ranges, the detectors are mounted on the main board, and each detector adopts different angles to form a plurality of independent detection areas, and the space 100 is divided by the plurality of independent detection areas. Multiple small partitions (such as the blank area in Figure 1), each small partition is a non-sensing area. Since the divided non-sensing area is small enough (less than the area of the object to be measured, which is smaller than the volume of the object to be measured, such as smaller than the body shape), when the human body enters the space 100, at least one of the plurality of detectors A detector detects the infrared signal of the human body. Further, when the human body is in different partitions, since each partition is smaller than the human body shape, two detectors of two adjacent different sections of the human body are triggered to generate a sensing signal, thereby confirming that someone is in the space 100. Inside. Since the space 100 is divided into very small partitions by a plurality of detectors, it is very easy to detect the human body and improve the accuracy of detection.

The spatial zone detecting device 10 of the present invention can detect not only the moving human body but also the spatial zone detecting device 10 of the present invention when the person is stationary. Specifically, since the spatial partition detecting apparatus 10 of the present invention divides the space 100 into a plurality of independent detecting areas, the plurality of independent detecting areas divide the space 100 into a plurality of small partitions, each of which is smaller than the body shape of the human body. When a person enters the space 100, the person enters the space 100 from the entrance of the space 100, and at least two detectors of the detection area at the entrance of the space 100 can receive the infrared signal of the human body, thereby determining that a person enters the space 100; When a person is stationary in the space 100, since any two detectors at the entrance of the space 100 can receive the infrared signals of the human body in sequence and generate a sensing signal when the person enters the space 100, it can be determined that the person is in the space 100. At the same time, after the person enters the space 100, since the sensing signal generated by any one of the detectors is not received for a long time, it can be determined that the person is in the space 100 and remains stationary; when the person leaves the space 100, the human body The passing area can be detected by the detector, and the detecting area can receive the infrared signal of the human body and generate the sensing signal in the space 100 and at the exit of the space 100, according to the detecting area in the space 100, The sequence of the sensed signals of the detectors at the source 100 and the space 100 can confirm that the person leaves the space 100.

Additionally, the spatial zone detecting device 10 of the present invention can also determine the location of the human body that is stationary within the space 100. In the spatial partition detecting device 10 of the present invention, the position number of each detector has a preset correspondence relationship with the sensing signal generated by the detector, that is, the sensing signal output by each detector is bound to the detector, and can be This binding relationship gets the specific location of the probe. The preset correspondence between the position number of each detector and the sensing signal generated by the detector may be pre-stored in the memory, and when any one of the sensing signals is received, the preset corresponding to the sensing signal may be stored in the memory. Find the corresponding detector and the location information of the detector in the relationship. Therefore, when the human body enters the space 100 and is in different partitions, any two detectors can detect the infrared signal of the human body and generate two sensing signals, according to which the presence of a person can be determined to exist in the space 100, and Searching for the detectors corresponding to the two sensing signals and the position information of the two detectors from the pre-stored preset correspondences according to the two sensing signals, and determining the person according to the location information of the two detectors The specific location within space 100.

Further, the spatial zone detecting device 10 of the present invention can also track the movement trajectory of the human body in the space 100. Specifically, in the spatial partition detecting apparatus 10 of the present invention, the position number of each detector has a preset correspondence relationship with the sensing signal generated by the detector, that is, the sensing signal output by each detector is bound to the detector. The specific location of the probe can be obtained according to the binding relationship. The preset correspondence between the position number of each detector and the sensing signal generated by the detector may be pre-stored in the memory, and when any one of the sensing signals is received, the preset corresponding to the sensing signal may be stored in the memory. Find the corresponding detector and the location information of the detector in the relationship. Therefore, when the human body moves in the space 100, the sensing signals at different times can be received, and the corresponding detectors and the detectors are searched for in the preset correspondence stored in the memory according to the received sensing signals at different times. The position information further determines the specific position, moving direction, and moving trajectory of the human body according to the position information of each detector and the chronological order.

The present invention also contemplates a spatial partition detection system comprising the spatial partition detection apparatus 10 described above, and control means communicatively coupled to a plurality of detectors in the spatial partition detection apparatus 10, the control apparatus for receiving The sensing signals generated by the plurality of detectors control the switches of the corresponding devices in the space 100 according to the sensing signals.

The space partition detection system of the invention can perform real-time and accurate detection and calculation on the presence or absence of a person in the space 100, realizes intelligent control of various devices in time and no time in the space 100, and pairs the space according to the movement of the human body. Intelligent selection and control of devices in different locations within 100.

As can be seen from the foregoing, the spatial zone detecting device 10 divides the space 100 into a plurality of independent detecting regions, and the plurality of independent detecting regions divide the space 100 into a plurality of small partitions, each of which is smaller than the body shape of the human body. When a person enters the space 100, the person enters the space 100 from the entrance of the space 100, and at least two detectors of the detection area at the entrance of the space 100 can receive the infrared signal of the human body, thereby determining that someone enters the space 100. In turn, when the person is in the space 100, when the person enters the space 100, any two detectors at the entrance of the space 100 can receive the infrared signals of the human body in sequence to generate the sensing signals. And sent to the control device, the control device can determine that the person is in the space 100 according to the received sensing signals, and after the person enters the space 100, the sensing signal generated by triggering any one of the detectors is not received for a long time. In turn, it can be determined that the person is in the space 100 and remains stationary; when the person leaves the space 100, the area through which the human body passes can be detected by the detector, and the detection area is at least two in the space 100 and at the exit of the space 100. The detector can receive the infrared signal of the human body and generate the sensing signal, and send the generated sensing signal to the control device, and the control device According to the sequence of the sense signal detector detecting different regions confirmed leave space 100, thereby controlling the space 100 within the device is turned off.

The spatial zone detection system of the present invention can also determine the location of the human body that is stationary within the space 100. Specifically, in the spatial partition detecting apparatus 10 used in the spatial partition detecting system of the present invention, the position number of each detector has a preset correspondence relationship with the sensing signal generated by the detecting, that is, the sensing signals output by each detector are respectively Bind to the probe and obtain the specific location of the probe based on the binding relationship. The preset correspondence between the position number of each detector and the sensing signal generated by the detector may be pre-stored in the memory, and when any one of the sensing signals is received, the preset corresponding to the sensing signal may be stored in the memory. Find the corresponding detector and the location information of the detector in the relationship. Therefore, when the human body enters the space 100 and is in different zones, any two detectors can detect the infrared signal of the human body and generate two sensing signals, and after the control device receives the two sensing signals, according to the two senses The measurement signal may determine that a person exists in the space 100, and according to the two sensing signals, find a detector corresponding to the two sensing signals and a position of the two detectors from a preset correspondence relationship in the pre-existing memory. Information, and based on the location information of the two detectors, the specific location of the person within the space 100 can be determined.

The spatial zone detection system of the present invention can also track the movement trajectory of the human body within the space 100. Specifically, in the spatial partition detecting apparatus 10 used in the spatial partition detecting system of the present invention, the position number of each detector has a preset correspondence relationship with the sensing signal generated by the detecting, that is, the sensing signals output by each detector are respectively Bind to the probe and obtain the specific location of the probe based on the binding relationship. The preset correspondence between the position number of each detector and the sensing signal generated by the detector may be pre-stored in the memory, and when the control device receives any one of the sensing signals, the pre-stored according to the sensing signal may be stored in the memory. Find the corresponding detector and the position information of the detector in the corresponding relationship. Therefore, when the human body moves in the space 100, the control device can receive the sensing signals at different moments, and search for corresponding detectors according to the received sensing signals at different moments in the preset correspondence relationship stored in the memory. The position information of the detector further determines the specific position, moving direction and moving trajectory of the human body according to the position information of each detector and the chronological order, so as to move the direction and the moving trajectory to different positions in the space 100 according to the specific position of the human body. The device is intelligently selected and controlled.

The present invention also constructs a spatial partition detection method, which can be implemented by applying the foregoing spatial partition detection system, and the spatial partition detection method comprises the following steps:

S1: Acquire a sensing signal.

S2, determining whether two or more sensing signals are received, and if so, determining that an object exists in the space 100. In this step, since the spatial partition detecting apparatus 10 described above divides the space 100 into a plurality of independent detecting areas, the plurality of independent detecting areas divide the space 100 into a plurality of small partitions, each of which is smaller than the body shape of the human body. . When a person enters the space 100, the person enters the space 100 from the entrance of the space 100, and at this time, at least two detectors of the detection area at the entrance of the space 100 can receive an infrared signal of the human body, thereby determining that a person enters the space 100. Therefore, when the control device can receive any two or more sensing signals, it can be determined that someone is in the space 100.

Wherein, the position information of the detector includes the position of any one, two, three, ... N detectors of the plurality of detectors.

S4. Determine a position or a movement trajectory of the measured object based on the position information.

Specifically, in the spatial partition detecting apparatus 10 used in the spatial partition detecting system of the present invention to which the spatial partition detecting method of the present invention is applied, the position number of each detector has a preset correspondence relationship with the generated sensing signal, that is, The sensing signal output by each detector is bound to the detector, and the specific position of the detector can be obtained according to the binding relationship. When any one of the sensing signals is received, the corresponding detector and the position information of the detector may be searched from the preset correspondence stored in the memory according to the sensing signal. Therefore, after acquiring the sensing signal sent by the detector in the space 100, the position of the detector and the detector corresponding to each sensing signal can be determined according to the preset correspondence between the sensing signal and the detector position number. Information, and determine the position or movement trajectory of the object based on the position information of each detector.

Taking the schematic diagram of FIG. 1 as an example, where A1 ^' , A2 ^' , A3 ^' , A4 ^' , A5 ^' , and A6 ^' are the detector A1, the detector A2, the detector A3, the detector A4, and the detector mounted on the main board. A5, detector A6 projection area in the plane projection diagram, B1 ^' , B2 ^' , B3 ^' , B4 ^' , B5 ^' , B6 ^' is on the main board of the detector B1, detector B2, detector B3, detection Schematic diagram of the projection area of the detector B4, the detector B5, and the detector B6 in a plane.

When the human body moves from the 1st partition to the 17th partition along the illustrated path, the detector B1, the detector B2, and the detector B3, the detector A1, the detector A2, and the detector A3 both generate sensing signals, and the control unit according to the detector The sensing signals generated by B1, detector B2, and detector B3, detector A1, detector A2, and detector A3 are obtained by detector B1, detector B2, and detector B3, detector A1, detector A2, and detection. The specific installation position of the device A3, and then the specific installation position of the detector B1, the detector B2, and the detector B3, the detector A1, the detector A2, and the detector A3 determine the movement trajectory of the human body, thereby realizing the moving direction of the human body. And the tracking of the motion track.

The following is to set B1, B2, B3, ..., Bn detectors in the horizontal direction on the main board, and set A1, A2, A3, ..., Am detectors in the vertical direction on the main board as an example, then the space partition detection The device 10 can divide the space 100 into (n + 1) * (m + 1) partitions, each partition being smaller than the body shape of the human body. The method for realizing intelligent detection control by the spatial partition detection system is:

As shown in FIG. 1, when the human body enters the space 100, it is assumed that the human body enters from the first partition. When the human body reaches the first partition, since the body shape is larger than the partition, when the human body reaches the first partition, the detector B1 and The detector A1 can detect the infrared signal existing in the human body, and send the converted sensing signal b1 and the sensing signal b2 to the control device. When the human body enters the space and remains stationary, since the partition is small, After the human body enters the first partition, the body shape is actually in the first partition and the second partition, or in the first partition and the eighth partition. Taking the first partition and the eighth partition as an example, at this time, both the detector B1 and the detector A1 can detect the infrared signal of the human body, and respectively send the sensing signal b1 and the sensing signal a1 to the control device, and the control device according to The sensed signal b1 and the sensed signal a1 can determine that a person has entered the space 100, thereby controlling the associated device within the open space 100. After the human body leaves the space 100, since all the detectors in the space partition detecting device do not generate the sensing signal, it can be judged that there is no person in the space 100, and thus the corresponding device in the control device control space 100 is closed; or, when the human body When leaving the space 100, it is assumed that the exit is set at the first partition. When the human body leaves the space 100, the detector around the first area of the sensing area will detect the infrared signal of the human body again, wherein the detector sets the B1 and the detector. A1 finally receives the infrared signal of the human body, so that the human body can leave the space 100 according to the sensing signal sent by the detector B1 and the detector A1. When the human body moves in the space 100, for example, the human body moves from the first partition to the third partition in the horizontal direction. At this time, the detector B1 first detects the infrared signal of the human body, and then the detector B2 detects the infrared signal of the human body. Finally, the detector B3 detects the infrared signal of the human body, and sequentially transmits the converted sensing signal b1, the sensing signal b2 and the sensing signal b3 to the control device, and the control device according to the received sensing signal b1 and the sensing signal The sequence of b2 and the sensing signal b3, and the positions of the detector B1, the detector B2 and the detector B3 determine the moving direction and the moving trajectory of the human body.
