Description

Technical Field

[0001] The present invention relates to a motion sensor, in particular to a motion sensor with an adaptive adjustment function, and also relates to an adaptive adjustment method for the motion sensor. Background Art

[0002] Motion sensors generate a sensing signal when they detect movement, activating a target device (such as a light, fan, or similar device). Therefore, motion sensors are widely used. However, existing motion sensors (such as microwave sensors and infrared motion sensors) can generate false alarms due to self-excitation (or other external interference). Consequently, the target device controlled by the motion sensor may be erroneously turned on and off, causing the target device to not function properly. For example, a lighting fixture in a garage might be frequently turned on and off due to a false alarm from a microwave sensor, causing other lighting fixtures in the same group to also frequently turn on and off. Summary of the Invention

[0003] According to one embodiment of the present invention, a mobile sensor with adaptive adjustment functionality is provided. The sensor includes a sensing module, a processing module, and a communication module. The sensing module generates a sensing signal. The processing module is connected to the sensing module and calculates the duration of the sensing signal. The communication module is connected to the processing module. When the processing module is in a preset state and the duration of the sensing signal is greater than or equal to a target threshold, the processing module generates a control signal and transmits the control signal to a target device via the communication module.

[0004] In one embodiment, when the processing module continuously receives multiple sensing signals, the processing module calculates the number of the sensing signals and the duration of each sensing signal. When the number of the sensing signals is greater than or equal to a predetermined number and the duration of each sensing signal is equal to a predetermined standard value, the processing module enters an adaptive adjustment state and increases the target threshold.

[0005] In one embodiment, when the processing module is in a preset state, the target threshold value is equal to a preset standard value.

[0006] In one embodiment, when the processing module is in the adaptive adjustment state, the processing module increases the target threshold value so that the target threshold value is equal to the product of the preset standard value and the adaptive adjustment coefficient.

[0007] In one embodiment, the sensing module is a microwave sensor or an infrared motion sensor.

[0008] According to another embodiment of the present invention, a method for adaptively adjusting a motion sensor is provided, comprising the following steps: generating a sensing signal via a sensing module; calculating a duration of the sensing signal via a processing module; generating a control signal via the processing module when the sensing signal duration is greater than or equal to a target threshold value under a preset state; and transmitting the control signal to a target device via a communication module.

[0009] In one embodiment, the method further includes the following steps: calculating, by the processing module, the number of the plurality of sensing signals and the duration of each sensing signal upon consecutively receiving the plurality of sensing signals; and entering, by the processing module, an adaptive adjustment state and increasing the target threshold value when the number of the plurality of sensing signals is greater than or equal to a preset number and the duration of each sensing signal is equal to a preset standard value.

[0010] In one embodiment, when the processing module is in a preset state, the target threshold value is equal to a preset standard value.

[0011] In one embodiment, when the processing module is in the adaptive adjustment state, the processing module increases the target threshold value so that the target threshold value is equal to the product of the preset standard value and the adaptive adjustment coefficient.

[0012] In one embodiment, the sensing module is a microwave sensor or an infrared motion sensor.

[0013] As described above, the motion sensor with adaptive adjustment function and the adaptive adjustment method thereof according to the embodiments of the present invention may have one or more of the following advantages:

[0014] (1) In one embodiment of the present invention, a motion sensor includes a sensing module, a processing module, and a communication module. The sensing module generates a sensing signal. The processing module is connected to the sensing module and calculates the duration of the sensing signal. The communication module is connected to the processing module. When the processing module is in a preset state and the duration of the sensing signal is greater than or equal to the target threshold value, the processing module generates a control signal and transmits the control signal to the target device through the communication module. When the processing module continuously receives multiple sensing signals, the processing module calculates the number of the multiple sensing signals and the duration of each sensing signal. When the number of the multiple sensing signals is greater than or equal to the preset number and the duration of each sensing signal is equal to the preset standard value, the processing module enters an adaptive adjustment state and increases the target threshold value. Through the above-mentioned adaptive adjustment function based on the duration of the sensing signal, the processing module can timely increase the target threshold value when the sensing module falsely alarms due to self-excitation or other external interference, thereby reducing its sensitivity. In this way, the processing module can ensure that the control signal is generated to control the target device only when the sensing module actually detects a moving object, so that the target device can operate normally. Therefore, the accuracy of the motion sensor can be greatly improved.

[0015] (2) In one embodiment of the present invention, when the processing module is in the adaptive adjustment state, the processing module increases the target threshold value so that the target threshold value is equal to the product of the preset standard value and the adaptive adjustment coefficient. Through the above-mentioned design based on the adaptive adjustment coefficient, the user can adjust the adaptive adjustment coefficient according to the characteristics of different sensing modules, so that the adaptive adjustment function can effectively prevent false alarms from the sensing modules and improve the accuracy of the motion sensor. Therefore, the use of the motion sensor can be more flexible and its application can be more extensive.

[0016] (3) In one embodiment of the present invention, the adaptive adjustment function based on the duration of the sensing signal can be effectively implemented solely through the timing and counting functions of the processing module, without requiring additional electronic components or complex software. Furthermore, this adaptive adjustment function can effectively improve the accuracy of the motion sensor. Therefore, this adaptive adjustment function does not significantly increase the cost of the motion sensor, allowing the motion sensor to meet the needs of different applications.

[0017] (4) In one embodiment of the present invention, the adaptive adjustment function based on the duration of the sensing signal can effectively optimize the performance of the mobile sensor. Therefore, the mobile sensor can be widely used in Internet of Things systems or other intelligent systems (such as smart garage systems, smart home systems, etc.) and can achieve high accuracy. Therefore, the mobile sensor is indeed in line with future development trends.

[0018] (5) In one embodiment of the present invention, the motion sensor has a simple design and can implement the adaptive adjustment function without requiring additional electronic components or complex software. Therefore, the desired effect can be achieved without significantly increasing the cost. Therefore, the motion sensor can achieve extremely high practicality and can truly meet the needs of practical applications. BRIEF DESCRIPTION OF THE DRAWINGS

For ease of understanding, identical components in the following embodiments are illustrated with the same symbols.

[0028] See also Figure 1 , which is a block diagram of the circuit structure of a motion sensor with adaptive adjustment function according to the first embodiment of the present invention. As shown in the figure, the motion sensor 1 includes a sensing module 11, a processing module 12, a communication module 13 and a power module 14.

[0029] The processing module 12 is connected to the sensing module 11. In one embodiment, the processing module 12 may be a microcontroller (MCU). In another embodiment, the processing module 12 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other similar components. In one embodiment, the sensing module 11 may be a microwave sensor. In another embodiment, the sensing module 11 may be a motion infrared (PIR) sensor.

[0031] The power module 14 is connected to the processing module 14. In one embodiment, the power module 14 can be a rechargeable battery, such as a lithium-ion battery, a nickel-cadmium battery, a nickel-metal hydride battery, etc. In another embodiment, the power module 14 can be a primary battery, such as a carbon-zinc battery, an alkaline battery, etc.

[0032] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mobile sensor with adaptive adjustment function according to this embodiment should still be included in the patent scope of the present invention.

[0033] See also Figure 2 , which is a schematic diagram of the operating state of the motion sensor with adaptive adjustment function of the first embodiment of the present invention. As shown in the figure, when the sensing module 11 detects a moving object MB (such as a person, vehicle, etc.), a sensing signal Ds is generated. The initial value of the sensing signal Ds generated by the sensing module 11 is a preset standard value (such as 500ms, 600ms, 700ms, etc., which can be adjusted according to actual needs). Since the moving object MB passes through the detection range of the sensing module 11, the sensing module 11 will be continuously triggered; thus, the duration of the sensing signal Ds will be greater than the preset standard value. If the moving object MB stops on the path passing through the sensing module 11, the sensing module 11 may generate multiple sensing signals Ds, but the duration of these sensing signals Ds will be greater than or at least equal to the preset standard value.

[0034] Before executing the adaptive adjustment function, the processing module 12 is in a preset state. The processing module 12 calculates the duration of the sensing signal Ds. When the processing module 12 detects the rising edge of the sensing signal Ds, the processing module 12 starts timing. When the processing module 12 detects the falling edge of the sensing signal Ds, the processing module 12 ends timing. The processing module 12 compares the duration of the sensing signal Ds with a target threshold value, and in the preset state, this target threshold value may be equal to a preset standard value. When the processing module 12 is in the preset state and the duration of the sensing signal Ds is greater than or equal to the target threshold value, the processing module 12 generates a control signal Cs and transmits the control signal Cs to the target device TD through the communication module 13. The above-mentioned target device TD may be, but is not limited to, a lighting device or various electrical appliances (such as a fan, air conditioner, television, etc.).

[0035] The sensing module 11 may generate a sensing signal Ds due to self-excitation or other external interference (such as a fan). However, since the sensing module 11 does not detect the moving object MB, the sensing module 11 will not be continuously triggered. As a result, the duration of the sensing signal Ds will be equal to the preset standard value. When the processing module 12 continuously receives multiple sensing signals Ds, the processing module 12 calculates the number of the multiple sensing signals Ds and the duration of each sensing signal Ds. The processing module 12 performs an adaptive adjustment function when the number of the multiple sensing signals Ds is greater than or equal to the preset number and the duration of each sensing signal Ds is equal to the preset standard value. At this time, the processing module 12 enters the adaptive adjustment state from the initial state. The above-mentioned preset number can be, but is not limited to, 10. In another embodiment, the above-mentioned preset number can also be 5, 8, or 15, which can be adjusted according to actual needs. After entering the adaptive adjustment state, the processing module 12 increases the target threshold value to reduce the sensitivity of the sensing module 11. The processing module 12 may increase the target threshold value so that the target threshold value is equal to the product of the preset standard value and the adaptive adjustment coefficient, as shown in the following formula (1):

[0036] Th=K×Td…(1)

[0037] Where Th is the target threshold; K is the adaptive adjustment coefficient; and Td is the preset standard value. The adaptive adjustment coefficient is greater than 1 but less than 2. In this embodiment, the adaptive adjustment coefficient may be 1.2. In another embodiment, the adaptive adjustment coefficient may be 1.3, 1.4, 1.5, or 1.8, which can be adjusted based on actual needs. If the processing module 12 detects that the duration of the sensing signal Ds is greater than the preset standard value, the processing module 12 resets the count. In yet another embodiment, the adaptive adjustment coefficient may be greater than 2, such as 2.5, 2.8, or 3, which can be adjusted based on actual needs.

[0038] Thus, through the aforementioned adaptive adjustment function based on the duration of the sensing signal Ds, the processing module 12 can promptly raise the target threshold value, thereby reducing its sensitivity, when the sensing module 11 issues a false alarm due to self-excitation or other external interference. This ensures that the processing module 12 only generates the control signal Cs to control the target device TD when the sensing module 11 actually detects the moving object MB, allowing the target device TD to operate normally. Consequently, the accuracy of the motion sensor 1 can be significantly improved.

[0039] As can be seen from the above, in this embodiment, when the processing module 12 is in the adaptive adjustment state, the processing module 12 increases the target threshold value so that the target threshold value equals the product of the preset standard value and the adaptive adjustment coefficient. Through this design based on the adaptive adjustment coefficient, the user can adjust the adaptive adjustment coefficient according to the characteristics of different sensing modules 11. This adaptive adjustment function can effectively prevent false alarms from the sensing module 11, thereby improving the accuracy of the motion sensor 1. Therefore, the motion sensor 1 can be used more flexibly and has a wider range of applications.

[0040] Furthermore, in this embodiment, the adaptive adjustment function based on the duration of the sensing signal Ds can be effectively implemented solely through the timing and counting functions of the processing module 12, without requiring additional electronic components or complex software. Furthermore, this adaptive adjustment function can effectively improve the accuracy of the motion sensor 1. Therefore, this adaptive adjustment function does not significantly increase the cost of the motion sensor 1, allowing the motion sensor 1 to meet the needs of various applications.

[0041] Furthermore, in this embodiment, the aforementioned adaptive adjustment function based on the duration of the sensing signal Ds can effectively optimize the performance of the motion sensor 1. Therefore, the motion sensor 1 can be widely used in Internet of Things systems or other intelligent systems (such as smart garage systems and smart home systems), achieving high accuracy. Therefore, the motion sensor 1 is indeed in line with future development trends.

[0042] Furthermore, in this embodiment, the motion sensor 1 has a simple design and can implement the adaptive adjustment function without requiring additional electronic components or complex software. Therefore, the desired functionality can be achieved without significantly increasing costs. Therefore, the motion sensor 1 can achieve extremely high practicality and truly meet the needs of practical applications.

[0043] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mobile sensor with adaptive adjustment function according to this embodiment should still be included in the patent scope of the present invention.

[0044] See also Figure 3 , which is a first schematic diagram of a sensing signal of a motion sensor with an adaptive adjustment function according to a first embodiment of the present invention, and please also refer to Figure 1-2. As shown in the figure, when the sensing module 11 of the motion sensor 1 detects a moving object MB, the sensing module 11 generates a sensing signal Ds. Since the moving object MB passes through the detection range of the sensing module 11, the sensing module 11 will be continuously triggered; thus, the duration of the sensing signal Ds will be greater than the preset standard value. When the processing module 12 detects the rising edge of the sensing signal Ds, the processing module 12 starts timing. When the processing module 12 detects the falling edge of the sensing signal Ds, the processing module 12 ends timing. The processing module 12 compares the duration of the sensing signal Ds with the target threshold value, and in the preset state, this target threshold value may be equal to the preset standard value. When the processing module 12 is in the preset state and the duration of the sensing signal Ds is greater than or equal to the target threshold value, the processing module 12 generates a control signal Cs and transmits the control signal Cs to the target device TD through the communication module 13 to turn on the target device TD.

[0045] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mobile sensor with adaptive adjustment function according to this embodiment should still be included in the patent scope of the present invention.

[0046] See also Figure 4 , which is a second schematic diagram of the sensing signal of the motion sensor with adaptive adjustment function according to the first embodiment of the present invention, and please also refer to Figure 1-2 As shown in the figure, the sensing module 11 may generate a sensing signal Ds due to self-excitation or other external interference. However, since the sensing module 11 does not detect the moving object MB, the sensing module 11 will not be continuously triggered. In this case, the duration of the sensing signal Ds will be equal to a preset standard value. When the processing module 12 continuously receives multiple sensing signals Ds, it calculates the number of sensing signals Ds and the duration of each sensing signal Ds. When the number of sensing signals Ds is greater than or equal to the preset number and the duration of each sensing signal Ds is equal to the preset standard value, the processing module 12 performs an adaptive adjustment function. At this point, the processing module 12 enters the adaptive adjustment state from the initial state and increases the target threshold value to reduce the sensitivity of the sensing module 11. In this manner, although the processing module 12 still generates a control signal Cs to activate the target device TD, the next time the sensing module 11 is triggered by self-excitation or other external interference, the sensitivity of the sensing module 11 has been lowered, so the processing module 12 will not generate a control signal Cs to activate the target device TD.

[0047] As can be seen above, through the adaptive adjustment function based on the duration of the sensing signal Ds, the processing module 12 can promptly raise the target threshold value, thereby reducing its sensitivity, when the sensing module 11 issues a false alarm due to self-excitation or other external interference. This ensures that the processing module 12 only generates the control signal Cs to control the target device TD when the sensing module 11 actually detects the moving object MB, allowing the target device TD to operate normally. Consequently, the accuracy of the motion sensor 1 can be significantly improved.

[0048] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mobile sensor with adaptive adjustment function according to this embodiment should still be included in the patent scope of the present invention.

[0049] It's worth noting that existing motion sensors 1 may generate false alarms due to self-excitation (or other external interference). Consequently, the target device TD controlled by the motion sensor 1 may be erroneously turned on and off, causing the target device TD to not function properly. In contrast, according to an embodiment of the present invention, the motion sensor 1 includes a sensing module 11, a processing module 12, and a communication module 13. The sensing module 11 generates a sensing signal Ds. The processing module 12 is connected to the sensing module 11 and calculates the duration of the sensing signal Ds. The communication module 13 is connected to the processing module 12. When the processing module 12 is in a preset state and the duration of the sensing signal Ds is greater than or equal to a target threshold, the processing module 12 generates a control signal Cs and transmits the control signal Cs to the target device TD via the communication module 13. When the processing module 12 continuously receives multiple sensing signals Ds, it calculates the number of the sensing signals Ds and the duration of each sensing signal Ds. When the number of the sensing signals Ds is greater than or equal to a preset number and the duration of each sensing signal Ds is equal to a preset standard value, the processing module 12 enters an adaptive adjustment state and increases the target threshold. By adaptively adjusting the duration of the sensing signal Ds, the processing module 12 can promptly raise the target threshold, reducing its sensitivity, when the sensing module 11 issues a false alarm due to self-excitation or other external interference. This ensures that the processing module 12 only generates the control signal Cs to control the target device TD when the sensing module 11 actually detects the moving object MB, ensuring that the target device TD operates normally. Consequently, the accuracy of the motion sensor 1 is significantly improved.

[0050] Furthermore, according to an embodiment of the present invention, when processing module 12 is in the adaptive adjustment state, processing module 12 increases the target threshold value so that the target threshold value equals the product of a preset standard value and an adaptive adjustment coefficient. This adaptive adjustment coefficient design allows users to adjust the adaptive adjustment coefficient based on the characteristics of different sensing modules 11. This adaptive adjustment function effectively prevents false alarms from the sensing module 11, thereby improving the accuracy of the motion sensor 1. Consequently, the motion sensor 1 can be used with greater flexibility and has a wider range of applications.

[0051] Furthermore, according to embodiments of the present invention, the adaptive adjustment function based on the duration of the sensing signal Ds can be effectively implemented solely through the timing and counting functions of the processing module 12, without requiring additional electronic components or complex software. Furthermore, this adaptive adjustment function can effectively improve the accuracy of the motion sensor 1. Therefore, this adaptive adjustment function does not significantly increase the cost of the motion sensor 1, allowing the motion sensor 1 to meet the needs of various applications.

[0052] Furthermore, according to embodiments of the present invention, the aforementioned adaptive adjustment function based on the duration of the sensing signal Ds can effectively optimize the performance of the motion sensor 1. Therefore, the motion sensor 1 can be widely used in Internet of Things systems or other intelligent systems (such as smart garage systems and smart home systems), achieving high accuracy. Therefore, the motion sensor 1 is indeed in line with future development trends.

[0053] Furthermore, according to the embodiments of the present invention, the motion sensor 1 has a simple design and can implement the adaptive adjustment function without requiring additional electronic components or complex software. Therefore, the desired functionality can be achieved without significantly increasing costs. Therefore, the motion sensor 1 can achieve extremely high practicality and truly meet the needs of practical applications. As can be seen from the foregoing, the motion sensor 1 with adaptive adjustment function according to the embodiments of the present invention can indeed achieve excellent technical results.

[0055] Step S51 : Generate a sensing signal Ds via the sensing module 11 .

[0056] Step S52 : The processing module 12 calculates the duration of the sensing signal Ds.

[0057] Step S53: Generate a control signal Cs when the processing module 12 is in a preset state and the duration of the sensing signal Ds is greater than or equal to the target threshold. The processing module 12 generates a control signal Cs when the processing module 12 is in a preset state and the duration of the sensing signal Ds is greater than or equal to the target threshold. When the processing module 12 is in the preset state, the target threshold is equal to the preset standard value.

[0058] Step S54 : Transmit the control signal Cs to the target device TD via the communication module 13 .

[0059] Step S55 : Calculate the number of the sensing signals Ds and the duration of each sensing signal Ds by the processing module 12 after continuously receiving the sensing signals Ds.

[0060] Step S56: When the number of sensing signals Ds is greater than or equal to a predetermined number and the duration of each sensing signal Ds is equal to a predetermined standard value, the processing module 12 enters an adaptive adjustment state and increases the target threshold. When in the adaptive adjustment state, the processing module 12 increases the target threshold until the target threshold equals the product of the predetermined standard value and the adaptive adjustment coefficient. The adaptive adjustment coefficient is greater than 1 but less than 2. The adaptive adjustment coefficient can also be greater than 2 and can be adjusted based on actual needs.

[0061] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made according to the adaptive adjustment method of the mobile sensor of this embodiment should still be included in the patent scope of the present invention.

[0062] Although the steps of the method described in the present invention are shown and described in a particular order, the order of operation of each method can be changed, and some steps can be performed in a reverse order, or some steps can be performed simultaneously with other steps. In another embodiment, different steps can be implemented in an intermittent and / or alternating manner.

[0063] In summary, according to an embodiment of the present invention, the motion sensor 1 includes a sensing module 11, a processing module 12, and a communication module 13. The sensing module 11 generates a sensing signal Ds. The processing module 12 is connected to the sensing module 11 and calculates the duration of the sensing signal Ds. The communication module 13 is connected to the processing module 12. When the processing module 12 is in a preset state and the duration of the sensing signal Ds is greater than or equal to a target threshold, the processing module 12 generates a control signal Cs and transmits the control signal Cs to the target device TD via the communication module 13.

This adaptive adjustment function based on the duration of the sensing signal Ds allows the processing module 12 to promptly raise the target threshold, thereby reducing the sensitivity of the sensing module 11, when it generates a false alarm due to self-excitation or other external interference. In this way, the processing module 12 can ensure that the control signal Cs is generated to control the target device TD only when the sensing module 11 actually detects the moving object MB, so that the target device TD can operate normally. Therefore, the accuracy of the motion sensor 1 can be greatly improved.

[0064] Furthermore, according to an embodiment of the present invention, when processing module 12 is in the adaptive adjustment state, processing module 12 increases the target threshold value so that the target threshold value equals the product of a preset standard value and an adaptive adjustment coefficient. This adaptive adjustment coefficient design allows users to adjust the adaptive adjustment coefficient based on the characteristics of different sensing modules 11. This adaptive adjustment function effectively prevents false alarms from the sensing module 11, thereby improving the accuracy of the motion sensor 1. Consequently, the motion sensor 1 can be used with greater flexibility and has a wider range of applications.
