Abstract

A position detection method, comprising: acquiring position information fed back most-recently by a microwave sensor (40) and used for expressing the position at where a detection target is located (S10); determining, on the basis of the position information, whether the position of the detection target is located within a preset detection area (S20); and if yes, determining that the detection target has always been located within the preset detection area (S30). As such, even if the microwave sensor (40) acquires no position information of the detection target throughout a subsequent period, the detection target can still be considered to be continuously located within the preset detection area. This is applicable in cases in which the detection target is stationary in the preset detection area or the level of activity of the detection target does not reach a detection threshold of the microwave sensor (40). As such, achieved is the goal of utilizing the microwave sensor (40) to implement static detection and the detection of a target having a low activity level. Also provided are an air conditioner (1), a control method for the air conditioner (1), and a computer-readable storage medium. Erroneous determinations affecting user experience are avoided when the air conditioner is detecting a target human body.

具体实施方式Detailed ways
本发明首先提供一种基于微波传感器的位置检测方法，图1是根据本发明一个实施例的位置检测方法的示意性流程图。参见图1，本发明的位置检测方法包括：The present invention first provides a position detection method based on a microwave sensor. FIG. 1 is a schematic flowchart of a position detection method according to an embodiment of the present invention. Referring to Fig. 1, the position detection method of the present invention includes:
步骤S10，获取微波传感器最近一次反馈的用于表示检测目标所在位置的位置信息。可以理解的是，微波传感器最近一次反馈的位置信息也就是微 波传感器最后一次反馈检测目标的位置信息，也即是，微波传感器能够反馈的检测目标最新的位置信息。具体地，根据位置检测方法的目的不同，检测目标可以为目标人体，也可以为其他能够运动的目标物体。Step S10, acquiring the position information indicating the position of the detection target that was fed back by the microwave sensor most recently. It can be understood that the latest position information fed back by the microwave sensor is the position information of the detection target fed back by the microwave sensor for the last time, that is, the latest position information of the detection target that can be fed back by the microwave sensor. Specifically, according to the purpose of the position detection method, the detection target may be the target human body or other movable target objects.
步骤S20，根据位置信息判断检测目标的位置是否处于预设检测区域内；若是，则转步骤S30。预设检测区域可以为预先设定的区域，也可以为集成有微波传感器的装置在其工作过程中根据一些设定参数自动确定的区域。Step S20, according to the position information, determine whether the position of the detection target is within the preset detection area; if so, go to step S30. The preset detection area may be a preset area, or may be an area automatically determined by the device integrated with the microwave sensor according to some set parameters during its operation.
步骤S30，判定检测目标始终处于预设检测区域内。也就是说，检测目标的位置一直处于该预设检测区域内。Step S30, it is determined that the detection target is always within the preset detection area. That is to say, the position of the detection target is always within the preset detection area.
本发明的位置检测方法，通过获取微波传感器最近一次反馈的用于表示检测目标位置的位置信息，如果根据位置信息判断出检测目标的位置处于预设检测区域内，则认为检测目标始终处于预设检测区域内。也就是说，即使微波传感器在之后的时间内一直都没有获取到检测目标的位置信息，仍然可以认为检测目标持续处于预设检测区域内。本发明的位置检测方法适用于检测目标在预设检测区域内处于静止状态或检测目标的活动量没有达到微波传感器的检测阀值的情况。由此，达到了利用微波传感器实现静态检测和低活动量目标检测的目的。The position detection method of the present invention obtains the position information used to indicate the position of the detection target fed back by the microwave sensor last time. If it is determined according to the position information that the position of the detection target is within the preset detection area, it is considered that the detection target is always in the preset detection area. within the detection area. That is to say, even if the microwave sensor has not acquired the position information of the detection target in the following period of time, it can still be considered that the detection target is continuously within the preset detection area. The position detection method of the present invention is suitable for the situation that the detection target is in a static state in the preset detection area or the activity of the detection target does not reach the detection threshold of the microwave sensor. Thus, the purpose of using the microwave sensor to realize static detection and low-activity target detection is achieved.
相比于现有技术中利用微波传感器是否在一定时间内检测到检测目标的活动信息来判断目标是否存在的方式，本发明的位置检测方法更加精准地反映了检测目标实际所处的位置，检测准确度较高，避免了误判的可能性。Compared with the method in the prior art that uses whether the microwave sensor detects the activity information of the detection target within a certain period of time to determine whether the target exists, the position detection method of the present invention more accurately reflects the actual position of the detection target. The accuracy is high, avoiding the possibility of misjudgment.
图2是根据本发明一个实施例的根据位置信息判断检测目标所在位置是否处于预设检测区域内的示意性流程图。参见图2，在一些实施例中，根据位置信息判断检测目标所在位置是否处于预设检测区域内的步骤S20具体可包括：FIG. 2 is a schematic flowchart of determining whether the location of a detection target is within a preset detection area according to location information according to an embodiment of the present invention. Referring to FIG. 2, in some embodiments, the step S20 of judging whether the location of the detection target is within the preset detection area according to the location information may specifically include:
步骤S21，以微波传感器所在位置为原点建立坐标系。坐标系的X轴可以为平行于微波传感器所安装的装置的横向方向，坐标系的Y轴可以但不限制为垂直于X轴且指向微波传感器所安装的装置的前侧的方向。Step S21, establishing a coordinate system with the position of the microwave sensor as the origin. The X-axis of the coordinate system may be parallel to the lateral direction of the device on which the microwave sensor is mounted, and the Y-axis of the coordinate system may be, but not limited to, a direction perpendicular to the X-axis and pointing to the front side of the device on which the microwave sensor is mounted.
步骤S22，确定预设检测区域在坐标系中的坐标范围、并根据位置信息确定检测目标在坐标系中的坐标。Step S22: Determine the coordinate range of the preset detection area in the coordinate system, and determine the coordinates of the detection target in the coordinate system according to the position information.
步骤S23，当检测目标在坐标系中的坐标处于预设检测区域在坐标系中的坐标范围内时判定检测目标的位置处于预设检测区域内。相应地，当检测目标在坐标系中的坐标处于预设检测区域在坐标系中的坐标范围之外时可 认为检测目标的位置没有处于预设检测区域内。Step S23, when the coordinates of the detection target in the coordinate system are within the coordinate range of the preset detection area in the coordinate system, it is determined that the position of the detection target is within the preset detection area. Correspondingly, when the coordinates of the detection target in the coordinate system are outside the coordinate range of the preset detection area in the coordinate system, it can be considered that the position of the detection target is not within the preset detection area.
本实施例以微波传感器所在位置为原点建立坐标系，并将预设检测区域以及检测目标的位置信息都体现在坐标系中，非常明确地体现了检测目标与预设检测区域之间的位置关系，提高了检测目标所处位置的判断准确性。In this embodiment, the position of the microwave sensor is used as the origin to establish a coordinate system, and the position information of the preset detection area and the detection target are all embodied in the coordinate system, which clearly reflects the positional relationship between the detection target and the preset detection area. , which improves the accuracy of judging the location of the detection target.
图3是根据本发明另一个实施例的根据位置信息判断检测目标所在位置是否处于预设检测区域内的示意性流程图。进一步地，当检测目标在坐标系中的坐标处于预设检测区域在坐标系中的坐标范围内时判定检测目标的位置处于预设检测区域内的步骤S23具体可包括：FIG. 3 is a schematic flowchart of judging whether the location of the detection target is within a preset detection area according to the location information according to another embodiment of the present invention. Further, when the coordinates of the detection target in the coordinate system are within the coordinate range of the preset detection area in the coordinate system, the step S23 of determining that the position of the detection target is within the preset detection area may specifically include:
步骤S231，在坐标系中确定出一参考坐标范围，该参考坐标范围的边界与预设检测区域在坐标系中的坐标范围的边界邻近。具体地，参考坐标范围的边界可处于预设检测区域在坐标系中的坐标范围的边界内侧，也可以处于预设检测区域在坐标系中的坐标范围的边界外侧。In step S231, a reference coordinate range is determined in the coordinate system, and the boundary of the reference coordinate range is adjacent to the boundary of the coordinate range of the preset detection area in the coordinate system. Specifically, the boundary of the reference coordinate range may be inside the boundary of the coordinate range of the preset detection area in the coordinate system, or may be outside the boundary of the coordinate range of the preset detection area in the coordinate system.
步骤S233，判断检测目标在坐标系中的坐标是否处于参考坐标范围内；若是，则转步骤S235；若否，则可认为检测目标的位置没有处于预设检测区域内。Step S233, determine whether the coordinates of the detection target in the coordinate system are within the reference coordinate range; if so, go to step S235; if not, it can be considered that the position of the detection target is not within the preset detection area.
步骤S235，判定检测目标的位置处于预设检测区域内。Step S235, it is determined that the position of the detection target is within the preset detection area.
发明人认识到，要想准确地判断检测目标是否处于预设检测区域内，对于预设检测区域本身的要求比较精确，但对预设检测区域的边界要求不需要精确。也就是说，可以将预设检测区域的边界设置成一定的阈值范围，从而将预设检测区域的边界模糊化。为此，本实施例在坐标系中特别地确定出一边界与预设检测区域的坐标范围边界邻近的参考坐标范围，通过参考坐标范围来判断检测目标的位置是否处于预设检测区域内，模糊了预设检测区域的边界，考虑到了多种情况的可能性，提高了位置检测的准确性。The inventor realizes that in order to accurately determine whether the detection target is within the preset detection area, the requirements for the preset detection area itself are relatively precise, but the boundary requirements for the preset detection area do not need to be precise. That is to say, the boundary of the preset detection area may be set to a certain threshold range, so as to blur the boundary of the preset detection area. Therefore, in this embodiment, a reference coordinate range whose boundary is adjacent to the boundary of the coordinate range of the preset detection area is specially determined in the coordinate system, and whether the position of the detection target is within the preset detection area is determined by the reference coordinate range, and the fuzzy The boundary of the preset detection area is considered, and the possibility of various situations is considered, which improves the accuracy of position detection.
例如，微波传感器最近一次获取到的检测目标的位置坐标处于预设检测区域的边界附近，在之后再没有获取到检测目标的位置信息，此时，说明检测目标始终处于预设检测区域的边界附近，仍然可以准确地获取到检测目标的位置。For example, the position coordinates of the detection target acquired by the microwave sensor last time are near the boundary of the preset detection area, and the position information of the detection target is not obtained after that. At this time, it means that the detection target is always near the boundary of the preset detection area. , the position of the detection target can still be accurately obtained.
更进一步地，预设检测区域在坐标系中的坐标范围和参考坐标范围均可以为以坐标系的原点为圆心的扇形，以便于确定预设检测区域在坐标系中的坐标范围和检测目标的坐标。并且，预设检测区域在坐标系中的坐标范围的半径大于参考坐标范围的半径。也就是说，参考坐标范围处于预设检测区域 在坐标系中的坐标范围之内。Further, both the coordinate range of the preset detection area in the coordinate system and the reference coordinate range can be a sector with the origin of the coordinate system as the center of the circle, so as to determine the coordinate range of the preset detection area in the coordinate system and the detection target. coordinate. Moreover, the radius of the coordinate range of the preset detection area in the coordinate system is greater than the radius of the reference coordinate range. That is to say, the reference coordinate range is within the coordinate range of the preset detection area in the coordinate system.
具体地，当坐标系的X轴为平行于微波传感器所安装的装置的横向方向、坐标系的Y轴为垂直于X轴且指向微波传感器所安装的装置的前侧的方向时，预设检测区域在坐标系中的坐标范围和参考坐标范围所成的扇形的圆心角可以大于0°、且小于等于180°。Specifically, when the X-axis of the coordinate system is parallel to the lateral direction of the device on which the microwave sensor is installed, and the Y-axis of the coordinate system is a direction perpendicular to the X-axis and pointing to the front side of the device on which the microwave sensor is installed, the preset detection The central angle of the sector formed by the coordinate range of the region in the coordinate system and the reference coordinate range may be greater than 0° and less than or equal to 180°.
图4是根据本发明又一个实施例的根据位置信息判断检测目标所在位置是否处于预设检测区域内的示意性流程图。在一些实施例中，当检测目标在坐标系中的坐标处于预设检测区域在坐标系中的坐标范围内时判定检测目标的位置处于预设检测区域内的步骤S23具体可包括：FIG. 4 is a schematic flowchart of judging whether the location of the detection target is within a preset detection area according to the location information according to yet another embodiment of the present invention. In some embodiments, when the coordinates of the detection target in the coordinate system are within the coordinate range of the preset detection area in the coordinate system, the step S23 of determining that the position of the detection target is within the preset detection area may specifically include:
步骤S232，按照预设的规则将预设检测区域在坐标系中的坐标范围分成若干个子坐标范围；Step S232, dividing the coordinate range of the preset detection area in the coordinate system into several sub-coordinate ranges according to a preset rule;
步骤S234，判断检测目标在坐标系中的坐标是否处于任一子坐标范围内；若是，则转步骤S236；Step S234, determine whether the coordinates of the detection target in the coordinate system are within any sub-coordinate range; if so, go to step S236;
步骤S236，判定检测目标的位置处于预设检测区域内。Step S236, it is determined that the position of the detection target is within the preset detection area.
相应地，若检测目标在坐标系中的坐标不处于任一子坐标范围内，则认为检测目标的位置没有处于预设检测区域内。Correspondingly, if the coordinates of the detection target in the coordinate system are not within any sub-coordinate range, it is considered that the position of the detection target is not within the preset detection area.
本实施例将预设检测区域在坐标系中的坐标范围分成若干个子坐标范围，仅需要比较检测目标的坐标与每个子坐标范围的坐标即可，精简了程序执行过程，提高了运算效率。This embodiment divides the coordinate range of the preset detection area in the coordinate system into several sub-coordinate ranges, and only needs to compare the coordinates of the detection target and the coordinates of each sub-coordinate range, which simplifies the program execution process and improves the operation efficiency.
在一个实施例中，预设检测区域在坐标系中的坐标范围为以坐标系的原点为圆心的扇形，以便于确定预设检测区域在坐标系中的坐标范围和检测目标的坐标。具体地，当坐标系的X轴为平行于微波传感器所安装的装置的横向方向、坐标系的Y轴为垂直于X轴且指向微波传感器所安装的装置的前侧的方向时，该扇形的圆心角大于0°、且小于等于180°。In one embodiment, the coordinate range of the preset detection area in the coordinate system is a sector with the origin of the coordinate system as the center of the circle, so as to determine the coordinate range of the preset detection area in the coordinate system and the coordinates of the detection target. Specifically, when the X-axis of the coordinate system is parallel to the lateral direction of the device on which the microwave sensor is installed, and the Y-axis of the coordinate system is a direction perpendicular to the X-axis and pointing to the front side of the device on which the microwave sensor is installed, the fan-shaped The central angle is greater than 0° and less than or equal to 180°.
进一步地，上述预设的规则(也即是预设检测区域在坐标系中的坐标范围的划分规则)为：将预设检测区域在坐标系中的坐标范围所呈现的扇形的半径等分成若干段，从而在扇形的半径上形成若干个分隔点；以坐标系的原点为圆心，以坐标系的原点至每个分隔点的距离为半径做出若干个圆弧线，从而利用若干个圆弧线将预设检测区域在坐标系中的坐标范围划分成若干个子坐标范围。Further, the above-mentioned preset rule (that is, the division rule of the coordinate range of the preset detection area in the coordinate system) is: dividing the radius of the sector presented by the coordinate range of the preset detection area in the coordinate system into several equal parts. segment, so as to form several separation points on the radius of the sector; take the origin of the coordinate system as the center of the circle, and make several arc lines with the distance from the origin of the coordinate system to each separation point as the radius, so as to use several arcs The line divides the coordinate range of the preset detection area in the coordinate system into several sub-coordinate ranges.
例如，预设检测区域在坐标系的其中一个坐标可以为[0，X n]，也就是说， 坐标范围所呈现的扇形的半径为X n。将X n等分成n份，从而在X轴上形成X 1、X 2、……X n-1、X n，n个坐标值，分别以坐标系原点到X 1、X 2、……、X n-1为半径做出若干个圆弧形曲线，相邻圆弧形曲线之间、以及最外侧圆弧形曲线与预设检测区域的边界曲线之间均形成了环形子坐标范围，邻近坐标系原点的圆弧形曲线与坐标系原点所围成的扇形区域也形成了一个子坐标范围。 For example, one of the coordinates of the preset detection area in the coordinate system may be [0, X n ], that is, the radius of the sector represented by the coordinate range is X n . Divide X n into n equal parts, so as to form X 1 , X 2 , ... X n-1 is a radius of several arc-shaped curves, and a ring-shaped sub-coordinate range is formed between adjacent arc-shaped curves, and between the outermost arc-shaped curve and the boundary curve of the preset detection area. The arc-shaped curve at the origin of the coordinate system and the fan-shaped area enclosed by the origin of the coordinate system also form a sub-coordinate range.
本领域技术人员应理解，上述实施例仅提供了一种预设规则的示意性设定方式，在一些替代性实施例中，上述预设的规则还可以有其他合适的设定方式，例如等分成若干个圆心角相同的小扇形区域，对于其他预设规则的设定方式这里不再赘述。Those skilled in the art should understand that the above-mentioned embodiments only provide a schematic setting method of the preset rules, and in some alternative embodiments, the above-mentioned preset rules may also have other suitable setting methods, such as etc. It is divided into several small fan-shaped areas with the same central angle, and the setting methods of other preset rules are not repeated here.
在一些实施例中，还提供一种空调器的控制方法，空调器控制方法包括：In some embodiments, a method for controlling an air conditioner is also provided, and the method for controlling an air conditioner includes:
按照上述任一实施例所涉及的位置检测方法检测预设检测区域内是否有目标人体存在；以及Detect whether there is a target human body in the preset detection area according to the position detection method involved in any of the above embodiments; and
根据检测结果调节空调器在预设检测区域内的送风状态。Adjust the air supply state of the air conditioner in the preset detection area according to the detection result.
如前所述，利用上述任一实施例所涉及的位置检测方法检测目标人体是否存在于预设检测区域内的检测结果比较准确，可避免因误判导致目标人体的送风体验不佳的问题。As mentioned above, using the position detection method involved in any of the above embodiments to detect whether the target human body exists in the preset detection area is relatively accurate, and the problem of poor air supply experience of the target human body due to misjudgment can be avoided. .
在一些实施例中，根据检测结果调节空调器在预设检测区域内的送风状态的步骤具体可包括：In some embodiments, the step of adjusting the air supply state of the air conditioner in the preset detection area according to the detection result may specifically include:
当空调器设定为朝向目标人体送风的直吹模式、且预设检测区域内有目标人体存在时，控制空调器朝向预设检测区域内送风。也就是说，当用户设定空调器正对目标人体送风时，利用本实施例的位置检测方法检测到预设检测区域内有人体存在时，可控制空调器向该预设检测区域送风，避免了误判的可能性。When the air conditioner is set to the direct blowing mode of supplying air toward the target human body, and the target human body exists in the preset detection area, the air conditioner is controlled to supply air toward the preset detection area. That is to say, when the user sets the air conditioner to supply air to the target human body, and the position detection method of this embodiment detects that there is a human body in the preset detection area, the air conditioner can be controlled to supply air to the preset detection area , to avoid the possibility of misjudgment.
当空调器设定为避开目标人体送风的防直吹模式、且预设检测区域内有存在目标人体时，控制空调器避开预设检测区域送风。也就是说，当用户设定空调器避开目标人体送风时，利用本实施例的位置检测方法检测到预设检测区域内有人体存在时，可控制空调器避开该预设检测区域送风，避免了误判的可能性。When the air conditioner is set to an anti-direct blowing mode that avoids the target human body to supply air, and there is a target human body in the preset detection area, the air conditioner is controlled to avoid the preset detection area to supply air. That is to say, when the user sets the air conditioner to avoid the target human body to send air, and the position detection method of this embodiment detects that there is a human body in the preset detection area, the air conditioner can be controlled to avoid the preset detection area to send air. wind, avoiding the possibility of misjudgment.
具体地，如果目标人体在预设检测区域内处于静止或活动量较小的状态(这种状态是非常常见的，例如目标用户周末宅在家里躺在沙发上看手机)。 基于现有技术的惯常思维，当利用微波传感器检测预设检测区域内是否有目标人体存在时，若微波传感器在预设时长内都没有检测到目标人体的活动信息，就会认为预设检测区域内没有目标人体。这种判定结果往往与实际情况相反。若依据上述判定结果调节空调器，可想而知，空调器的运行与目标人体的期望也是相反的，这会严重影响用户的使用体验。本实施例的位置检测方法可以基于微波传感器实现静态或活动量小的目标检测，采用本实施例的位置检测方法可以准确地判定目标人体是否处于预设检测区域中，从而控制空调器执行正确的送风模式。Specifically, if the target human body is in a state of stillness or a small amount of activity in the preset detection area (this state is very common, for example, the target user stays at home on the weekend and looks at the mobile phone on the sofa). Based on the conventional thinking of the prior art, when the microwave sensor is used to detect whether there is a target human body in the preset detection area, if the microwave sensor does not detect the activity information of the target human body within the preset time period, the preset detection area will be considered There is no target human body in it. The result of this judgment is often the opposite of the actual situation.
