Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

Embodiments of the present invention provide a detection head, a detection system and a method. Wherein, the detection head includes at least two sensors arranged at a predetermined distance apart, wherein each sensor has a corresponding sensor detection area, and the sensor detection areas of all the sensors in the detection head do not completely overlap so that in the different The completely overlapping areas form the detection area of the detection head; according to the detection result of the sensor of the detected object in the detection area of the detection head, or according to the detection result of the sensor of the detected object in the detection area of the detection head and obtain the detection result timing to determine the location and/or state of the detected object.

In a specific embodiment, the embodiment of the present invention may include two or more sensors arranged at a preset distance along the vertical direction, wherein the distance between any two sensors can be adjusted according to the actual use scene. setting, which is not limited in this embodiment of the present invention. At the same time, "along the vertical direction" means that there is a preset distance between the sensors in the vertical direction, which can be that the sensor sensor1 and the sensor sensor2 are arranged in the vertical direction as shown in Figure 1, or it can be as shown in Figure 1 2 shows a certain distance staggered along the horizontal and vertical directions, which is not limited in this embodiment of the present invention.

In yet another specific embodiment, the embodiment of the present invention may include two or more sensors arranged at a predetermined distance apart along the horizontal direction, wherein the distance between any two sensors can be adjusted according to the actual use scene. The setting is not limited in this embodiment of the present invention. At the same time, "along the horizontal direction" means that there is a preset distance between the sensors in the horizontal direction, which can be arranged along the horizontal direction as shown in Figure 3, or along the horizontal and vertical lines as shown in Figure 2. The vertical direction is staggered by a certain distance, which is not limited in this embodiment of the present invention. It can be seen that if it is "staggered by a certain distance along the horizontal and vertical directions", the structure is the same as that of the aforementioned embodiment of "setting a predetermined distance apart in the vertical direction".

As shown in Figure 4a, the sensor detection area S1 of the sensor sensor can generally be an open space range; as shown in Figure 4a is a longitudinal sectional view, the sensor detection area S1 of the sensor sensor is a conical open space, so its The longitudinal section is fan-shaped. If it is desired to limit the spatial range of the sensor detection area, it can be realized by a detection area limit mechanism as shown in Figure 4b and Figure 4c, so that the sensor detection area of a sensor is limited to a long and narrow plane area (Figure 4b ) or a spatial region with a certain thickness (Fig. 4c). Fig. 4b and Fig. 4c are also longitudinal sectional views, and when the sensor detection area is a long and narrow plane area, its longitudinal section is a line as shown in Figure 4b; when the sensor detection area is a space area with a certain thickness, its The cross section is rectangular as shown in Figure 4c.

In some application fields of the present invention, if the sensor detection area of each sensor or one of the sensors can be limited, the range of incomplete overlapping areas can be expanded, that is, the range of the detection head detection area can be expanded. Certainly, the schematic diagrams of the detection areas of these types of sensors are for illustrative purposes only, and are not intended to limit the embodiments of the present invention. Meanwhile, Fig. 4d and Fig. 4e show the schematic diagrams of "horizontal extension" and "longitudinal extension" of the sensor detection area when the sensor detection area of the sensor is a long and narrow plane area or a space area with a certain thickness. Among them, "horizontal extension" can be used for multiple sensors of the detection head to be arranged vertically to form multiple horizontal sensor detection areas; while "longitudinal extension" can be used for multiple sensors of the detection head to be arranged horizontally to A plurality of vertical sensor detection areas are formed.

Fig. 5a-Fig. 5d are schematic diagrams showing exemplary arrangement of sensors in several detection heads, which are longitudinal sectional views of the detection head as shown in Fig. 4a-Fig. The detection area is sectioned in the vertical direction, so when the sensor detection area is a sheet or a space area with a certain thickness, the longitudinal section view is a line or a rectangle; when the sensor detection area is a conical sheet, the longitudinal section view is A fan-shaped area. These diagrams can be considered as sensors arranged in the vertical direction and scanned in the horizontal direction; certainly those skilled in the art can understand that only the diagrams are rotated 90 degrees to be an embodiment in which the sensors are arranged in the horizontal direction and scanned in the vertical direction.

As shown in Figure 5a, the sensor detection areas of two or more sensors of the detection head are parallel, so that the range of incomplete overlapping areas can be expanded to the greatest extent, that is, the range of the detection area of the detection head is expanded. Of course, this is only a way to realize the technical solutions of the embodiments of the present invention, and in actual use, different detection purposes can be achieved by combining the sensor detection areas of multiple sensors. For example, as shown in Figure 5b, the sensor detection areas of two sensors may intersect, or the ends overlap as shown in Figure 5c, or the sensor detection areas of three sensors overlap as shown in Figure 5d. Of course, this is just an example. The number of sensors and the spatial distribution of the sensor detection areas are not limited in the embodiment of the present invention. It is only necessary to satisfy the fact that the sensor detection areas of all sensors do not completely overlap to achieve the purpose of the invention in the embodiment of the present invention. Of course, the schematic diagrams of the layout of these sensor detection areas are only for illustrative purposes, and are not a limitation to the embodiment of the present invention; those skilled in the art can understand that the sensor detection areas can be set by themselves according to needs, and only need to meet It is sufficient that "the sensor detection areas of all sensors do not completely overlap", and the present invention does not make a limitation on this.

As shown in Figure 5a, each detection head can include two or more sensors, and the sensor detection area of the sensor is a long and narrow area, which can also be said to be sheet-shaped or sheet-shaped with a certain thickness; As shown in 5a, the sensor detection areas of these sensors are all parallel to each other. This is only an actual structure of the embodiment of the present invention, rather than limiting the embodiment of the present invention. In order to explain the working principle and mechanism of the embodiment of the present invention more clearly, this structure is taken as an example for description. The detection head, as shown in Figure 5a, can be arranged in a vertical direction to detect falls. The detection head as shown in Figure 5e can also be arranged along the horizontal direction, as shown in Figure 3, to detect the moving track or standing/lying posture of the detected target. At the same time, each of the above-mentioned detection heads can be arranged vertically or horizontally or obliquely. Those skilled in the art can understand that the detection head can be set by itself according to the needs, and the present invention does not do this. out of limit.

In an actual application scenario, one or more detection heads may be included, which can improve the detection effect and accuracy, or obtain reliable detection results in a wide range of application scenarios.

At the same time, the embodiment of the present invention also proposes a detection system using any of the aforementioned detection heads, which includes a detection head and a judgment module, and the judgment module is used to The detection result of the sensor, or according to the detection result of the sensor of the detection object in the detection area of the detection head and the timing of obtaining the detection result, determine the position and/or state of the detected object.

If the detection result of the first sensor changes from active or static to no one, and the detection result of the second sensor is active, then it is judged that the state of the detected target is bending over;

If the detection result of the first sensor changes from no one to active or static, the detection result of the second sensor remains active or static, and at this time, the state of the detected target is determined to be bending over and getting up;

If the detection result of the first sensor is no one, and the detection result of the second sensor is static, then it is judged that the state of the detected target is squatting or bending down; if the state has not changed for a period of time, the detected target state discrimination sitting;

Wherein the installation position of the first sensor unit is higher than the installation position of the second sensor unit.

Wherein, according to the detection result and timing of the sensor, judging the position and/or state of the detected target includes at least one of the following:

If the detection result of the first sensor changes from unmanned to active or static, and the detection result of the second sensor changes from unmanned to active or static, the state of the detected target is judged as standing up from the ground;

If the detection result of the first sensor changes from active or stationary to unmanned, then the detection result of the second sensor is active or stationary to unmanned, and the second sensor is unmanned minus the time when the first sensor is unmanned The value of the time is relatively short, and at this time, it is judged that the state of the detected target is a fast fall or a fast slide.

In another embodiment, the detection head includes two or more sensors arranged at a predetermined distance apart along the horizontal direction, then according to the detection results of the sensors in the detection area of the detection head, or according to the detected The detection result of the sensor of the target in the detection area of the detection head and the timing of obtaining the detection result, judging the position and/or state of the detected target includes at least one of the following:

The above-mentioned logics are implemented by using two sensors (the first sensor and the second sensor). Those skilled in the art can understand that the detection logic can be realized by using two sensors; of course, more sensors can be used in order to improve the detection accuracy, but its logic and principle are the same as the foregoing examples, and will not be repeated here repeat.

At the same time, sensors for different detection results can also have different logics. Some sensors can output two detection results: yes or no; while some sensors can output three detection results: yes, no, and whether there is movement. For the detection results of different sensors, the technical solutions of the embodiments of the present invention propose detection logics for the two sensors.

For example: when the sensor can detect the three states of presence, absence, and motion, its logic can be shown in Table 1:

Table 1: Logic for Three-State Detection Sensors

Of course, the above-mentioned Table 1 exemplifies "human" as the detection target, but the detection target in the embodiment of the present invention can obviously be all detection targets other than human beings. The above-mentioned embodiments are only for illustration rather than limitation to the embodiments of the present invention. At the same time, the whole text of the present invention uses "human" as an example to illustrate the detection target, and the detection target in the embodiment of the present invention can obviously be all detection targets other than human beings, and the present invention will not repeat them one by one.

For example: when the sensor can detect the presence and absence of these two states, its logic can be shown in Table 2:

Table 2: Logic for Dual State Detection Sensors

For example: if an optical sensor is used, the optical sensor can be a sensor such as a camera; it is a typical passive sensor that can carry out these three detection structures of presence, absence, and activity, and its logic can be as shown in Table 3;

Table 3: Logic for Employing Optical Sensors

For example: if a pyro-infrared sensor (PIR) is used, the pyro-infrared sensor is a typical passive sensor, which can detect whether there is a target to be detected according to the heat, that is, it can produce two detection results: yes or no. Its logic can be as shown in table 4;

Table 4: Logic using PIR sensor

For example: if an active sensor is used, such as radar, laser scanning, infrared scanning or ultrasonic scanning, etc., it can produce three detection results: presence, absence, and activity. Its logic can be as shown in Table 5;

Table 5: Logic for using active sensors

The above description is a preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, these improvements and modifications It should also be regarded as the protection scope of the present invention.
