Description

Technical Field

[0001] The present invention relates to the technical field of intelligent electric mosquito technology, and in particular to an Internet of Things electric mosquito system that can detect the presence of a human body and automatically start and stop. Background Art

[0002] The existing method of using electric mosquito coils is to turn on the switch to heat the mosquito coils or mosquito coil liquid and release the sensitive gas into the air. If the switch is not turned off manually, the mosquito coil liquid will continue to burn. On the one hand, if the mosquito coil liquid burns continuously for a long time, the electric mosquito coil liquid will be wasted, and if the electric mosquito coil device is forgotten to be turned off for a long time, it may cause a fire. On the other hand, the long-term uninterrupted burning of the mosquito coil liquid will make the concentration of the mosquito coil liquid in the surrounding environment too high, so that people are in a high concentration of sensitive gases for a long time, causing discomfort to people, and may even cause certain harm to the human body. There are also timer switch types for electric mosquito coils, but it is difficult for people to ensure that their daily routines are accurate to one minute every day, so there may be a misalignment between the timed working period of the electric mosquito coil device and the time period of the user's anti-mosquito demand, resulting in anti-mosquito loopholes. Therefore, the present invention proposes a new type of electric mosquito coil system for the Internet of Things. Summary of the invention

[0003] In order to solve the above technical problems, an Internet of Things electric mosquito coil system that can detect the presence of a human body and automatically start and stop is provided. This technical solution solves the problem that the use of the existing electric mosquito coil device proposed in the above background technology is to turn on the switch to heat the mosquito coil sheet or mosquito coil liquid and emit sensitive gas into the air. If the switch is not turned off manually, the mosquito coil liquid will continue to burn. On the one hand, the mosquito coil liquid will burn continuously for a long time, wasting the electric mosquito coil liquid, and if the electric mosquito coil device is forgotten to be turned off for a long time, it may cause a fire. On the other hand, even if the electric mosquito coil device is turned on and off at a fixed time, there is a time difference with the user's mosquito prevention needs, resulting in mosquito prevention loopholes.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: An Internet of Things electric mosquito system capable of automatically starting and stopping by detecting the presence of a human body comprises a human presence detection module, a laser light module, a cloud server module, a WIFI network module, a main control module and an electric mosquito module, wherein the human presence detection module is a human body detector for detecting human activities in a specific area, the laser light module is a rectangular laser light, the laser light and the human body detector are installed in the same direction for visually indicating the coverage range of the human body detector, and there are two laser lights, one for rectangular light output and the other for rectangular grid light output, which clearly indicate the sensing range and can be adjusted up, down, left and right to adapt to the application environment.

[0005] Preferably, the main control module uses an intelligent gateway as a root node.

[0006] Preferably, the cloud server module is Tencent Cloud or Huawei Cloud server.

[0007] Preferably, the main control module adopts a control chip, accesses the Internet through a WIFI network module, connects to an MQTT server, receives and sends instructions, and uploads status information of the electric mosquito device.

[0008] Preferably, mobile devices such as mobile phones can also receive and send instructions to the control chip and upload status information of the electric mosquito device through WIFI.

[0009] Preferably, the instructions sent specifically include working, sleeping, querying and clearing, and the uploaded status information specifically includes working / sleeping, total working time, and countdown of remaining mosquito coil liquid.

[0010] Preferably, when the human presence detection module detects the presence of a human body, it inputs a signal to the control chip, and the control chip controls the relay to supply power to the PTC heater in the electric mosquito module; and when the human presence detection module detects the departure of a human body, it inputs a signal to the control chip, and the control chip controls the relay to disconnect the power supply to the PTC heater in the electric mosquito module and stop working.

[0011] Preferably, the human detector is a millimeter-wave radar detector. When a signal of human presence is detected, a status signal of the human body is monitored in real time, and the status signal includes the distance between the human body and the human detector. When the signal of human presence is detected disappears, it is determined whether the distance between the human body and the detector before the disappearance is equal to a preset detection range threshold. When the distance between the human body and the detector before the disappearance is equal to the detection range threshold, a signal that the human body leaves the detection range is uploaded. When the distance between the human body and the detector before the disappearance is less than the detection range threshold, a signal that the human body is still within the detection range is uploaded, and the signal of human presence is detected using the principle of the Doppler effect.

[0012] Preferably, the status signal also includes the movement trend of the human body relative to the detector. When the distance between the human body and the detector before disappearing is equal to the detection range threshold, and the movement trend of the human body relative to the detector is away from the detector, a signal indicating that the human body has left the detection range is uploaded; otherwise, a signal indicating that the human body is still within the detection range is uploaded.

[0013] Preferably, if the distance between the human body and the human body detector increases within a recent set time period, the movement trend of the human body relative to the human body detector is to move away from the detector, and if the distance between the human body and the human body detector decreases within a recent set time period, the movement trend of the human body relative to the human body detector is to move closer to the human body detector.

[0014] Compared with the prior art, the present invention provides an Internet of Things electric mosquito system that can detect the presence of a human body and automatically start and stop, which has the following beneficial effects: 1. The irradiation field of the present invention is a rectangular laser light, and is installed in the same direction as the human body detector. The human body detectors currently on the market all use words to describe their detection range. Compared with the detectors on the market, the present invention can more clearly and visually point out the coverage range of the detector and avoid blind spots of the detector.

[0015] 2. The present invention stores data in a cloud server, which can solve the problem that the main controller has a small memory capacity and cannot save a large amount of user data. The cloud server is Tencent Cloud or Huawei Cloud Server. In order to realize a hybrid topology connection between different protocols and communicate with each other, the smart gateway is also a part of the network topology to receive data sent by the electric mosquito device and send the received data to the cloud server for storage. Storing data in the cloud server is more convenient and cost-effective than existing solutions.

[0016] 3. The electric mosquito device in the present invention is an Internet of Things device. Users can monitor the device status in real time, adjust settings and view capture data through mobile phone applets, etc. When the electric mosquito device fails, users can also learn about it at the first time. Compared with traditional electric mosquito devices, it is more environmentally friendly.

[0017] 4. When the electric mosquito system of the present invention detects that there is someone in the room, it can immediately send a signal to energize the PTC heating element, so that the PTC heating element heats the mosquito coil liquid and works; on the contrary, when there is no one in the room, the power supply of the PTC heating element is automatically disconnected, and the electric mosquito device automatically enters a dormant state, which reflects that the device is more intelligent.

[0018] 5. When the present invention detects the existence of a person based on the Doppler effect produced by human breathing, when a person faces away from or to the side of the detector, the detector cannot detect the breathing movement of the person to a large extent, which will cause inaccurate detection. The present invention detects the existence of a person based on the basic characteristics of the millimeter-wave radar detector that can obtain the speed and distance information of a person. The detector has a certain detection space, and a person cannot fly or disappear out of thin air. A person has only three states relative to the detector: within the detection area, remaining motionless, and the distance does not change; within the detection area, and walking outward, the distance gradually increases to outside the area; within the detection area, there is limb movement; the distance is within the detection range. This method is more accurate than the traditional human existence method. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Example 1 Please refer to Figure 1-Figure 4 As shown, an Internet of Things electric mosquito system that can detect the presence of a human body and automatically start and stop includes a human presence detection module, a laser light module, a cloud server module, a WIFI network module, a main control module and an electric mosquito module. The human presence detection module is a human detector for detecting human activities in a specific area. The laser light module is a rectangular laser light. The laser light and the human detector are installed in the same direction to visually indicate the coverage range of the human detector. There are two laser lights, one with a rectangular light output and the other with a rectangular grid light output, which clearly indicate the sensing range and can be adjusted up, down, left and right to adapt to the application environment.

[0022] It can be understood by those skilled in the art that the human body detectors currently on the market all use words to describe their detection range. The illumination field in the present invention is a rectangular laser light, and is installed in the same direction as the human body detector. Compared with the detectors on the market, the present invention can more clearly and visually indicate the coverage range of the detector and avoid blind spots of the detector.

[0023] Example 2 The main control module uses the intelligent gateway as the root node, and the cloud server module is Tencent Cloud or Huawei Cloud Server. Storing data in the cloud server can solve the problem that the main controller has a small memory capacity and cannot save a large amount of user data. The cloud server is Tencent Cloud or Huawei Cloud Server. In order to realize the hybrid topology connection between different protocols and communicate with each other, the intelligent gateway is also part of the network topology to receive the data sent by the electric mosquito device, and send the received data to the cloud server for storage. Storing data in the cloud server is more convenient and cost-effective than existing solutions.

[0024] Example 3 The main control module uses a control chip, which accesses the Internet through a WIFI network module, connects to the MQTT server, receives and sends instructions, and uploads the status information of the electric mosquito device. Mobile devices such as mobile phones can also receive and send instructions to the control chip through WIFI and upload the status information of the electric mosquito device. The instructions sent specifically include working, sleeping, querying, and clearing. The uploaded status information specifically includes working / sleeping, total working time, and countdown of the remaining mosquito coil liquid.

[0025] People skilled in the art can understand that the electric mosquito device in the present invention is an Internet of Things device. Users can monitor the device status in real time, adjust settings and view capture data through mobile phone applets, etc. When the electric mosquito device fails, the user can also learn about it at the first time. Compared with traditional electric mosquito devices, it is more environmentally friendly.

[0026] Example 4 When the human presence detection module detects the presence of a human body, it inputs a signal to the control chip, and the control chip controls the relay to supply power to the PTC heater in the electric mosquito module. When the human presence detection module detects the departure of a human body, it inputs a signal to the control chip, and the control chip controls the relay to disconnect the power supply to the PTC heater in the electric mosquito module and stop working.

[0027] People skilled in the art can understand that when the electric mosquito system of the present invention detects that there is someone in the room, it can immediately send a signal to energize the PTC heater, so that the PTC heater heats the mosquito coil liquid and works; on the contrary, when there is no one in the room, the power supply of the PTC heater is automatically disconnected, and the electric mosquito device automatically enters a sleep state, which reflects that the device is more intelligent.

[0028] Example 5 The human detector is a millimeter-wave radar detector. When a signal of human presence is detected, the human body status signal is monitored in real time. The status signal includes the distance between the human body and the human body detector. When the signal of human presence is detected disappears, it is determined whether the distance between the human body and the detector before the disappearance is equal to the preset detection range threshold. When the distance between the human body and the detector before the disappearance is equal to the detection range threshold, a signal that the human body has left the detection range is uploaded. When the distance between the human body and the detector before the disappearance is less than the detection range threshold, a signal that the human body is still within the detection range is uploaded. The signal of human presence is detected using the principle of Doppler effect.

[0029] The status signal also includes the movement trend of the human body relative to the detector. When the distance between the human body and the detector before disappearing is equal to the detection range threshold, and the movement trend of the human body relative to the detector is away from the detector, a signal that the human body has left the detection range is uploaded; otherwise, a signal that the human body is still within the detection range is uploaded.

[0030] If the distance between the human body and the human body detector increases in the most recent set time period, the movement trend of the human body relative to the human body detector is to move away from the detector. If the distance between the human body and the human body detector decreases in the most recent set time period, the movement trend of the human body relative to the human body detector is to move closer to the human body detector.

[0031] It is understandable to those skilled in the art that when the Doppler effect of human breathing is used for presence detection, when a person faces away from or to the side of the detector, the detector cannot detect the human breathing movement to a large extent, which will cause inaccurate detection. The present invention detects the presence of a human body based on the basic characteristics of the millimeter wave radar detector that can obtain the speed and distance information of a person. The detector has a certain detection space, and a person cannot fly or disappear out of thin air. A person has only three states relative to the detector: within the detection area, remains motionless, and the distance does not change; within the detection area, and walks outward, and the distance gradually increases to outside the area; within the detection area, there is limb movement; the distance is within the detection range. This method is more accurate than the traditional human presence method.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention. These changes and improvements fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
