Description

Technical Field

[0001] The present invention belongs to the technical field of sensors, and particularly relates to a module for adaptively adjusting a motion detection method and an implementation method thereof. Background Art

[0002] At present, the global market has an increasing demand for induction lamps, which can well reduce energy consumption and lower electricity costs.

[0003] At present, most of the induction lamps on the market are mainly single PIR modules or single microwave sensors, and they have the following main disadvantages:

[0004] 1. Most PIR modules are passive sensors that need to detect temperature changes. When the ambient temperature reaches above 35°C, the induction will be very insensitive. When there is a high-temperature wind blowing, false triggering will also occur, resulting in abnormal functions.

[0005] 2. When only using a microwave sensor, installing the microwave sensor outdoors or semi-outdoors is greatly affected by the environment. Even the slightest movement will cause the lamp to be falsely triggered, resulting in function failure.

[0006] Therefore, most of the common induction lamps on the market cannot be well applied to outdoor environments. Thus, there is an urgent need for a module that can adaptively adjust the motion detection method, which can adaptively identify the current lamp installation environment, improve the performance of induction lamps, reduce false triggering, and be suitable for outdoor environments with variable conditions. Summary of the Invention

[0007] The purpose of the present invention is to provide a module for adaptively adjusting a motion detection method to solve the problems raised in the above background art. The module for adaptively adjusting a motion detection method provided by the present invention has the characteristics of being able to adaptively identify the current lamp installation environment, improving the performance of induction lamps, reducing false triggering, and being suitable for outdoor environments with variable conditions.

[0008] Another purpose of the present invention is to provide an implementation method for a module for adaptively adjusting a motion detection method.

[0009] To achieve the above purpose, the present invention provides the following technical solution: A module for adaptively adjusting a motion detection method includes an MCU module, a microwave module, a temperature detection module, and a PIR module. Among them, the microwave module, the temperature detection module, and the PIR module are all signal-connected to the MCU module.

[0010] Further in the present invention, it further includes a rain drop detection module, and the rain drop detection module is signal-connected to the MCU module.

[0011] Further in the present invention, it further includes a first indicator light and a second indicator light that are signal-connected to the MCU module.

[0012] Further, in the present invention, the light-emitting color of the first indicator light is different from that of the second indicator light.

[0013] Further, in the present invention, a method for implementing a module with an adaptive adjustment motion detection method includes the following steps:

[0014] (1) After the lamp is powered on, the temperature detection module monitors the ambient temperature in real time;

[0015] (2) When the ambient temperature is less than 32 °C, the MCU module controls the PIR module to perform motion detection;

[0016] (3) When the ambient temperature is greater than or equal to 32 °C, the MCU module controls the microwave module to perform motion detection;

[0017] (4) In step (3), when the microwave module detects motion, the PIR module starts to work. If the PIR module does not detect motion within 5 minutes, it is recorded as a false judgment.

[0018] Further, in the present invention, in step (2), the microwave module does not work.

[0019] Further, in the present invention, in step (4), if the number of false judgments is greater than 5 times, it is considered that the current environment is not suitable for the microwave module to work, and the MCU module controls the temperature detection module and the microwave module to stop working until the lamp is powered on again.

[0020] Further, in the present invention, in step (4), when the microwave module detects motion, if the PIR module detects motion within 5 minutes, the number of false judgments is cleared.

[0021] Further, in the present invention, the rainfall is monitored by the rain drop detection module. When the rainfall is higher than the set threshold, if the microwave module detects motion, but the PIR module does not detect motion within 5 minutes, it is not recorded as a false judgment.

[0022] Further, in the present invention, when the microwave module detects motion, the first indicator light is lit, and when the PIR module detects motion, the second indicator light is lit.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In the present invention, the ambient temperature is monitored in real time by the temperature detection module. When the ambient temperature is less than 32 °C, the MCU module controls the PIR module to perform motion detection. When the ambient temperature is greater than or equal to 32 °C, the MCU module controls the microwave module to perform motion detection. The detection method is automatically switched according to the ambient temperature, so that the induction lamp is suitable for a changeable outdoor environment and reduces the energy consumption waste caused by false triggering;

[0025] 2. When the ambient temperature of the present invention is greater than or equal to 32°C, if the microwave module detects motion and the PIR module does not detect motion within 5 minutes, it is recorded as a misjudgment. If the number of misjudgments is greater than 5 times, it is considered that the current environment is not suitable for the microwave module to work, and the MCU module controls the temperature detection module and the microwave module to stop working, avoiding the waste of energy consumption caused by misjudgment.

[0026] 3. The present invention monitors the rainfall through the rain droplet detection module. When the rainfall is higher than the set threshold, if the microwave module detects motion but the PIR module does not detect motion within 5 minutes, it is not recorded as a misjudgment, avoiding the shutdown of the microwave detection function caused by the influence of rain droplets on the microwave module.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figure 1 , the present invention provides the following technical solutions: A module for adaptively adjusting the motion detection method, including an MCU module 1, a microwave module 2, a temperature detection module 3, and a PIR module 4, wherein the microwave module 2, the temperature detection module 3, and the PIR module 4 are all signal-connected to the MCU module 1.

[0032] By adopting the above technical solutions, the present invention monitors the ambient temperature in real time through the temperature detection module 3. When the ambient temperature is less than 32°C, the MCU module 1 controls the PIR module 4 to perform motion detection. When the ambient temperature is greater than or equal to 32°C, the MCU module 1 controls the microwave module 2 to perform motion detection, automatically switching the detection method according to the ambient temperature, making the induction lamp suitable for the changeable outdoor environment and reducing the waste of energy consumption caused by mis-triggering.

[0033] Specifically, it further includes a first indicator light and a second indicator light that are signal-connected to the MCU module 1. The first indicator light is red, and the second indicator light is blue.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 lies in that: specifically, it further includes a rain drop detection module 5, and the rain drop detection module 5 is signal-connected to the MCU module 1.

[0036] By adopting the above technical solution, the rain amount is monitored by the rain drop detection module 5. When the rain amount is higher than the set threshold, if the microwave module 2 detects movement, but the PIR module 4 does not detect movement within 5 minutes, it is not recorded as a misjudgment, avoiding the influence of raindrops on the microwave module 2 resulting in the shutdown of the microwave detection function.

[0037] Example 3

[0038] Furthermore, the implementation method of a module for adaptively adjusting the motion detection method of the present invention includes the following steps:

[0039] (1) After the lamp is powered on, the temperature detection module 3 monitors the ambient temperature in real time;

[0040] (2) When the ambient temperature is less than 32 °C, the MCU module 1 controls the PIR module 4 to perform motion detection, and the microwave module 2 does not work;

[0041] (3) When the ambient temperature is greater than or equal to 32 °C, the MCU module 1 controls the microwave module 2 to perform motion detection;

[0042] (4) In step (3), when the microwave module 2 detects movement, the PIR module 4 starts to work. If the PIR module 4 does not detect movement within 5 minutes, it is recorded as a misjudgment.

[0043] Specifically, in step (4), if the number of misjudgments is greater than 5 times, it is considered that the current environment is not suitable for the microwave module 2 to work, and the MCU module 1 controls the temperature detection module 3 and the microwave module 2 to stop working until the lamp is powered on again.

[0044] By adopting the above technical solution, when the ambient temperature of the present invention is greater than or equal to 32 °C, when the microwave module 2 detects movement, if the PIR module 4 does not detect movement within 5 minutes, it is recorded as a misjudgment. If the number of misjudgments is greater than 5 times, it is considered that the current environment is not suitable for the microwave module 2 to work, and the MCU module 1 controls the temperature detection module 3 and the microwave module 2 to stop working, avoiding the energy consumption waste caused by misjudgment.

[0045] Specifically, in step (4), when the microwave module 2 detects movement, if the PIR module 4 detects movement within 5 minutes, the number of misjudgments is cleared.

[0046] Specifically, the rainfall is monitored by the rain drop detection module 5. When the rainfall is higher than the set threshold, if the microwave module 2 detects movement, but the PIR module 4 does not detect movement within 5 minutes, it is not recorded as a false judgment.

[0047] Specifically, when the microwave module 2 detects movement, the first indicator light is lit. When the PIR module 4 detects movement, the second indicator light is lit.

[0048] In this invention, the MCU module 1 is preferably the HC89S003 type of Shanghai Xinsheng; the microwave module 2 is preferably the EDC116 type of Shenzhen Yitan; the temperature detection module 3 is preferably the NTC10D type of Ruilongyuan; the PIR module 4 is preferably the D220HX type of Quanzhixin; the rain drop detection module 5 is preferably the YS-JDQ type of Shenzhen Runde Electronics.

[0049] In summary, this invention monitors the ambient temperature in real time through the temperature detection module 3. When the ambient temperature is less than 32°C, the MCU module 1 controls the PIR module 4 to perform motion detection. When the ambient temperature is greater than or equal to 32°C, the MCU module 1 controls the microwave module 2 to perform motion detection, automatically switching the detection method according to the ambient temperature, making the induction lamp suitable for a changing outdoor environment and reducing energy consumption waste caused by false triggering. When the ambient temperature is greater than or equal to 32°C in this invention, when the microwave module 2 detects movement, if the PIR module 4 does not detect movement within 5 minutes, it is recorded as a false judgment. If the number of false judgments is greater than 5 times, it is considered that the current environment is not suitable for the microwave module 2 to work, and the MCU module 1 controls the temperature detection module 3 and the microwave module 2 to stop working, avoiding energy consumption waste caused by false judgments. This invention monitors the rainfall through the rain drop detection module 5. When the rainfall is higher than the set threshold, if the microwave module 2 detects movement, but the PIR module 4 does not detect movement within 5 minutes, it is not recorded as a false judgment, avoiding the influence of raindrops on the microwave module 2 resulting in the shutdown of the microwave detection function.
