Abstract
Description
Technical Field
[0001] This utility model belongs to the field of smart home control technology, specifically involving a multi-dimensional smart home lighting control module. Background Technology
[0002] With the development of smart home appliances, intelligent lighting control is increasingly being used in daily life. Voice control is a very popular intelligent control mode. However, this control mode has some defects. For example, the strength of the voice, the presence of noise interference, and the accuracy of the pronunciation can all cause a decrease in the control precision of the lighting fixtures. This can result in the lights not turning on when you want them to, or turning on automatically when you don't want them to. Therefore, it is necessary to provide a new control module to solve the technical problem of low control precision. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a multi-dimensional intelligent control module for home lighting, thereby solving the technical problem of poor accuracy of traditional single-dimensional lighting control modules.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a multi-dimensional home lighting intelligent control module, including a power supply, a lighting control chip and a lamp. The lamp is installed in the room. The power supply is used to supply power to the lighting control chip and the lamp. The lighting control chip controls the connection or disconnection between the lamp and the power supply. It also includes two laser sensors respectively installed on the inside and outside of the door and a photoelectric sensor installed in the room. The laser sensors and the photoelectric sensor are respectively connected to the lighting control chip and send detection signals to the lighting control chip.
[0005] As a preferred embodiment, it also includes a sound sensor installed in the room, which is connected to the lighting control chip and sends detection signals to the lighting control chip.
[0006] As a preferred embodiment, the system further includes a power control chip connected to the positive terminal of a power supply, a lighting control chip connected to the control voltage output terminal of the power control chip, and a luminaire connected to the drive voltage output terminal of the power control chip. The power control chip outputs an appropriate voltage to the lighting control chip and the luminaire, respectively.
[0007] As a preferred embodiment, the positive terminals of the two laser sensors are connected in parallel with the lighting control chip to the control voltage output terminal of the power control chip, and the positive terminals of the photoelectric sensor and the sound sensor are connected to different output pins of the lighting control chip, with the lighting control chip providing operating voltage to the photoelectric sensor and the sound sensor.
[0008] As a preferred embodiment, a MOSFET is connected between the power control chip and the lamp. The gate of the MOSFET is connected to the control voltage output terminal of the power control chip through a first transistor, and the base of the first transistor is connected to a pin of the lighting control chip.
[0009] The beneficial effects of this utility model are as follows: This utility model detects users entering and leaving the room by setting two laser sensors on the inside and outside of the door. The lighting control chip then determines whether the user has entered or left the room. At the same time, the brightness of the ambient light is detected by the photoelectric sensor. Combining the determination of the user's entry and exit from the room with the detection of the ambient light brightness, the system controls the lights in the room to be powered on or off. This allows for intelligent control without requiring user commands, thereby eliminating the influence of adverse factors such as noise and pronunciation accuracy on control precision and improving the control accuracy of the lighting fixtures.
[0010] This invention further captures ambient sounds by adding a sound sensor, which assists the lighting control chip in determining whether there are signs of user activity indoors. At the same time, users can use the sound sensor to control the lights by voice, realizing voice control function and improving the operability of the lights. Attached Figure Description
[0011] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:
[0012] Figure 1 This is a circuit diagram of the multi-dimensional intelligent home lighting control module described in this utility model;
[0013] Figure 1 The components are: 1. Power supply; 2. Lighting control chip; 3. Lighting fixture; 4. Laser sensor; 5. Photoelectric sensor; 6. Sound sensor; 7. Power control chip; 8. MOSFET; 9. First transistor; 10. Second transistor. Detailed Implementation
[0014] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.
[0015] like Figure 1 The multi-dimensional smart home lighting control module shown includes a power supply 1, a lighting control chip 2, and a lamp 4. The lamp 4 is installed in the room. The power supply 1 supplies power to the lighting control chip 2 and the lamp 3. The lighting control chip 2 controls the connection or disconnection between the lamp 3 and the power supply 1. It also includes two laser sensors 4 installed on the inside and outside of the door, and a photoelectric sensor 5 installed in the room. The laser sensors 4 and the photoelectric sensor 5 are connected to the lighting control chip 2 and send detection signals to the lighting control chip 2.
[0016] When a user enters the room from outside the door, the laser sensor 4 on the outside of the door detects the user first and sends a signal to the lighting control chip 2. The laser sensor 4 on the inside of the door then detects the user and sends a signal to the lighting control chip 2. The lighting control chip 2 determines that the user has entered the room based on the order in which the two signals are sent and ended. At the same time, the photoelectric sensor 5 sends the ambient light intensity signal to the lighting control chip 2. If the lighting control chip 2 determines that the user has entered the room but the ambient light is bright enough, it will not control the lamp 3 to be powered on. If the lighting control chip 2 determines that the user has entered the room and the ambient light brightness does not reach the preset brightness, it will control the lamp 3 to be powered on.
[0017] When the user leaves the room, the triggering order of the two laser sensors 4 is the reverse of the triggering order when the user enters the room. The lighting control chip 2 can then determine that the user has left the room and can immediately or after a delay turn off the lights 3 in the room.
[0018] In this embodiment, a sound sensor 6 is preferably installed in the room. The sound sensor 6 is connected to the light control chip 2 and sends a detection signal to the light control chip 2.
[0019] The sound sensor 6 can compensate for users' requests to turn off the lights indoors, such as when they want to rest. While voice control of lights via the sound sensor 6 is existing technology, when used in conjunction with the laser sensor 4 and photoelectric sensor 5, it effectively prevents the light fixture 3 from being turned on due to noise when no one is present. Therefore, the laser sensor 4 can effectively improve the accuracy of voice control of the lights.
[0020] This embodiment also includes a power control chip 7, which is connected to the positive terminal of the power supply. The lighting control chip 2 is connected to the control voltage output terminal V1 of the power control chip 7, and the lamp 3 is connected to the drive voltage output terminal V2 of the power control chip 7. The power control chip 7 outputs appropriate voltages to the lighting control chip 2 and the lamp 3 respectively to ensure the normal operation of each electrical component.
[0021] In this embodiment, the positive terminals of the two laser sensors 4 are preferably connected in parallel with the lighting control chip 2 to the control voltage output terminal V1 of the power control chip 7, while the positive terminals of the photoelectric sensor 5 and the sound sensor 6 are connected to different output pins of the lighting control chip 2. The lighting control chip 2 provides operating voltage to the photoelectric sensor 5 and the sound sensor 6. The advantage of this is that the lighting control chip 2 can activate the photoelectric sensor 5 and the sound sensor 6 according to preset conditions. For example, when the lighting control chip 2 uses an internal clock to determine day and night, it can turn on the light fixture 3 directly without activating the photoelectric sensor 5 to detect ambient light during nighttime. It can also stop activating the sound sensor 6 when no user is detected entering the room or when there are no users in the room, thereby reducing the energy waste caused by the standby of the photoelectric sensor 5 and the sound sensor 6.
[0022] In this embodiment, a MOSFET 8 is connected between the drive voltage output terminal V2 of the power control chip 7 and the lamp 3. The gate of the MOSFET 8 is connected to the control voltage output terminal V1 of the power control chip 7 through a first transistor 9. The base of the first transistor 9 is connected to a pin of the lighting control chip 2. When the lighting control chip 2 needs to light up the lamp 3, it only needs to send a high level to the base of the first transistor 9 to turn on the first transistor 9. After the first transistor 9 turns on, the MOSFET 8 turns on, thereby connecting the power supply to the lamp 3, and the lamp 3 will be lit. In order to avoid damage to the lighting control chip 2 caused by the continuous output of a high level, this embodiment achieves a self-locking function by connecting the negative terminal of the MOSFET 8 to the base of the first transistor 9 through a step-down resistor R. After the lighting control chip 2 lights up the lamp 3, it does not need to continuously output a high level to control the first transistor 9 to turn on, and the lamp 3 can remain lit. To protect the lighting control chip 2, a unidirectional diode D1 can be connected to the pin where the lighting control chip 2 is connected to the base of the first transistor 9, and the step-down resistor R can be connected to the negative terminal of the unidirectional diode D1.
[0023] To enable the lighting control chip 2 to control the lamp 3 to turn off, this embodiment further connects a second transistor 10 to the base of the first transistor 9. The transmitter of the second transistor 10 is grounded, and its base is connected to another output pin of the lighting control chip 2. When the lighting control chip 2 controls the second transistor 10 to conduct, it will pull down the base voltage of the first transistor 9, thereby turning off the MOSFET 8 and turning off the lamp 3.
[0024] The working principle of this utility model is as follows: This utility model detects the user's entry and exit from the room by setting two laser sensors 4 on the inside and outside of the door. The lighting control chip 2 determines whether the user has entered or left the room. At the same time, the brightness of the ambient light is detected by the photoelectric sensor 5. The system controls the lights in the room to be turned on or off by combining the results of the user's entry and exit from the room and the results of the ambient light detection. This can achieve intelligent control without the need for the user to give instructions, and the control accuracy is higher than that of voice control.
[0025] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
