Description

Technical Field

[0001] This invention relates to a controller, and more specifically, to an air conditioning controller. Background Technology

[0002] With rapid societal development and rising living standards, air conditioning, due to its high comfort level, is increasingly widely used in commercial establishments, hotels, office buildings, government offices, residential communities, high-end apartments, schools, hospitals, and other similar locations. Currently, air conditioning control primarily relies on ordinary infrared remote controls, requiring manual operation and operating only within a limited distance.

[0003] As people's demands for quality of life increase, more people expect the air conditioning to be on when they arrive at their destination, providing a comfortable environment. This necessitates further research and development of air conditioning controllers to meet the needs of remote and stable control. Summary of the Invention

[0022] Reference Figures 1 to 4 As shown, to achieve the above objectives, the present invention provides the following technical solution: an air conditioner controller, comprising a mounting base 1, a control board, a status acquisition terminal 3, an infrared remote controller 4, and a LoRa communication module 5;

[0023] The control board is installed in the mounting base 1 and is connected to the status acquisition terminal 3, the infrared remote controller 4 and the LoRa communication module 5 respectively;

[0024] Status acquisition terminal 3 is connected to the air conditioner control line to monitor the air conditioner status and generate status signals;

[0025] Infrared remote controller 4 is used to transmit infrared control signals;

[0026] The LoRa communication module 5 is used to connect to the user terminal and to receive and send induction signals;

[0027] The control board includes a control unit 21, and the control steps of the control unit 21 include:

[0028] S1, LoRa communication module 5 receives the sensing signal;

[0029] S2, the control board receives a status signal. When a status signal is available, it proceeds to S3; when no status signal is available, it proceeds to S4.

[0030] S3, the control board controls the infrared remote controller 4 to send out infrared control signals;

[0031] S4 sends a sensing signal through the LoRa communication module 5 to indicate that the air conditioner is not in standby mode.

[0032] This invention is primarily designed for the remote control of smart devices. It communicates with the air conditioner via infrared to control the device's power on / off and perform parameter settings. The control board accurately collects the device's current operating status by monitoring its operating current. Then, it interacts with a remote mobile phone via a LoRa 5 communication module, allowing operation of the device from the phone. The application software records data such as device power-on / off times and runtime, providing a reference for device maintenance.

[0033] The infrared remote controller 4 includes four sets of infrared transmitters 41 and infrared receivers 42, which are respectively arranged around the mounting base 1. The infrared transmitters 41 are used to generate infrared signals.

[0034] Infrared receiver 42 is used to receive reflected infrared signals;

[0035] The control board includes a computing module 22 and a temperature sensor 23. The temperature sensor 23 is located at the air outlet of the air conditioner and is used to monitor the air outlet temperature.

[0036] The steps of calculation module 22 include:

[0037] B1 receives the reflected infrared signal, obtains the room width x and room length y, and calculates the room area S;

[0038] B2, obtain the desired temperature value and start-up temperature value set by the user;

[0039] B3, calculates the working time to reach the desired temperature value based on the room area, air conditioner power information, and start-up temperature value;

[0040] B4 sets the working time for the start-up temperature value. When the working time is reached, an infrared control signal is sent to the air conditioner, causing the air conditioner to output the desired temperature value.

[0041] B5 monitors the air outlet temperature of the air conditioner through temperature sensor 23 and feeds it back to the user terminal through LoRa communication module 5.

[0042] The mobile app connects to the cloud to upload outdoor temperature, current location information, and riding gear information;

[0043] The steps of calculation module 22 also include:

[0044] Z1 obtains the outdoor temperature at the address location in the cloud, the distance between the address location and the controller, and riding equipment information through the LoRa communication module 5, and collects the air conditioner power information through the status acquisition terminal 3.

[0045] Z2, set the desired temperature value based on the outdoor temperature;

[0046] Z3 calculates travel time based on distance and riding gear information;

[0047] Z4 allows you to set the air conditioner start-up temperature based on travel time and air conditioner power.

[0048] The overall steps of the present invention include obtaining authorization from the mobile phone through the application software on the mobile phone. The authorization information includes GPS location information, temperature information corresponding to the location, location information of the target air conditioner, and cloud map information.

[0049] The distance between the user and the target location is determined based on the location information of the target air conditioner and GPS location information;

[0050] Based on cloud map information and the distance to the destination, travel time information can be exported;

[0051] Based on the corresponding temperature information, the most suitable desired temperature value for the user is calculated. Taking cooling as an example, the suitable temperature can be 24° or 26° or 5° below room temperature. The specific setting rules can be recorded by the user in the application via their mobile phone.

[0052] Furthermore, the starting temperature is calculated by taking into account the room area, the corresponding air conditioner power and cooling capacity, and the time it takes for the user to reach their destination. For example, air conditioner cooling capacity is expressed in watts (W), while the market commonly uses horsepower (HP) to describe its size. The conversion between the two is as follows: 1 HP of cooling capacity is approximately 2000 kilocalories, which, when converted to watts, should be multiplied by 1.162. That is, 1 HP of cooling capacity is 2000 kilocalories × 1.162 = 2324 W; as another example, 1.5 HP of cooling capacity is 2000 kilocalories × 1.5 × 1.162 = 2486 W. The cooling capacity required per square meter for a typical bedroom in a family is 115-145 W; the cooling capacity required per square meter for a living room and dining room is 145-175 W. Therefore, the shortest cooling time can be obtained based on the maximum power of the air conditioner and the area.

[0053] Furthermore, based on the ratio between the shortest cooling time and the travel time, the optimal operating power of the air conditioner is calculated, and the optimal starting temperature value is set accordingly.

[0054] Furthermore, the cooling time is set, and once the cooling time is reached, the air conditioner is switched from the start-up temperature value to the desired temperature value via a control signal.

[0055] Furthermore, the temperature sensor 23 detects the outlet air temperature, ensuring that the temperature remains stable under monitoring.

[0056] This ensures that users arrive at their destination in the most comfortable temperature environment.

[0057] The area of ​​the room is calculated using four infrared transmitters 41 and four infrared receivers 42. Infrared rays are emitted to the four sides, reflected back after reaching the walls, and received by the infrared receivers 42, thereby calculating the area of ​​the room.

[0058] This invention is primarily aimed at spaces that are predominantly horizontal, which are typically square in shape, allowing for a more accurate calculation of the current area.

[0059] There will inevitably be areas that cannot be detected by fixed-point infrared, which will reduce the accuracy of the device, but will not affect its use. Users can adjust the area range via their mobile phones after determining the initial area based on their understanding of the target location. They can increase or decrease the area range, thereby achieving the purpose of assisting in measurement.

[0060] Therefore, through the above design, this equipment can intelligently formulate an air conditioning and cooling plan based on the destination conditions. Furthermore, it selects an appropriate operating power during the cooling and cold preservation processes, thereby indirectly achieving energy savings.

[0061] It also includes a base 6, which is fixedly installed on the ceiling. The base 6 is provided with a lifting groove 61, and the mounting seat 1 is slidably connected in the lifting groove 61. The lifting groove 61 is provided with a lifting mechanism 62.

[0062] The mounting base 1 is equipped with four sets of diffusion devices 7, each corresponding to an infrared emitter 41.

[0063] The diffusion device 7 includes a diffusion mirror 71, a linkage rod 72, and a mirror housing 73. The diffusion mirror 71 is installed inside the mirror housing 73, and the mirror housing 73 is rotatably connected to the mounting base 1, with the lifting direction as the rotation axis direction.

[0064] The linkage rod 72 is connected to the base 6.

[0065] The mirror housing 73 is provided with an arc-shaped sliding groove 74. One end of the linkage rod 72 is fixedly connected to the base 6, and the other end is slidably connected to the sliding groove 74.

[0066] As the mounting base 1 slides along the lifting groove 61, the mirror housing 73 rotates along the rotation axis.

[0067] The diffuser 71 is a convex lens.

[0068] The rotation angle of the mirror housing 73 is 0-45°. When the mounting base 1 is raised or lowered to the bottom position, the infrared emitter 41 is set perpendicular to the diffuser 71.

[0069] The slide groove 74 is gradually curved from the high inner side to the low outer side along the height direction of the mirror housing 73.

[0070] The design of the diffusion device 7 is to diffuse the infrared signal emitted by the infrared transmitter 41, thereby fulfilling a comprehensive control function and avoiding the situation where the air conditioner cannot be triggered.

[0071] An installation hole is drilled in the ceiling, and the base 6 is installed in the installation hole. The lifting mechanism 62 enables the mounting base 1 to move the control board and infrared remote control 4 into the lifting groove 61, achieving the function of preventing moisture and dirt.

[0072] Furthermore, during the lifting and lowering process, the mirror housing 73 rotates, thereby diffusing the rays and increasing the diffusion range. The implementation steps include:

[0073] 1. Start the controller. At this time, the lifting mechanism 62 drives the mounting base 1 to move out and reach the lowest point. At this time, the diffuser 71 and the infrared remote controller 4 are in a vertical state.

[0074] 2. Activate the measurement function and measure the area of ​​the room using the infrared remote control 4;

[0075] 3. The control board performs the above series of calculations;

[0076] 4. Activate the control function. The infrared remote controller 4 continuously sends infrared signals and moves upward through the lifting mechanism 62. During the movement, the mirror housing 73 continuously rotates to diffuse the rays and ensure the air conditioner is activated.

[0077] The lifting mechanism 62 adopts a screw drive, which includes a rotating motor and a screw. One end of the screw is connected to the upper end of the mounting base 1. During the rotation of the screw driven by the rotating motor, the mounting base 1 moves up or down.

[0078] In addition, the design of the linkage rod 72 and the slide groove 74 is such that when the mounting base 1 is located at the top of the lifting groove 61, the mirror housing 73 and the infrared remote controller 4 form an angle of nearly 45°. At this time, one end of the linkage rod 72 is connected to the base 6, and the other end is located at the bottom of the slide groove 74. At this time, the linkage rod 72 is in an inclined state.

[0079] As the mounting base 1 moves downward, one end of the linkage rod 72 is fixedly and rotatably connected to the base 6. As the mounting base 1 moves downward, the other end of the linkage rod 72 moves in the slide groove 74 and drives the mirror housing 73 to rotate. When the mounting base 1 moves to the bottom of the lifting groove 61, the mirror housing 73 and the infrared remote controller 4 are in a vertical state, and the linkage rod 72 is also in an approximately vertical state with the mirror housing 73.

[0080] This increases the radiation diffusion range during the lifting and lowering of the mounting base 1, reduces blind spots in the room, and ensures control stability.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
