Description

Technical Field

[0001] The utility model belongs to the technical field of lighting control, and in particular relates to a lighting control system applied to a factory production workshop. Background Art

[0002] Factory production workshops are typically located in specific areas of the factory, with floor space determined by production scale and demand. The workshops are laid out according to the production process, with multiple functional areas such as raw material storage, processing, and assembly. These areas work together to form an efficient production line.

[0003] Factory production workshops are a vital component of industrial production. Through scientific layout, advanced equipment, and strict management, they ensure efficient production and high-quality products. In the future, with technological advancements and updated management concepts, production workshops will continue to introduce intelligent and green production methods to achieve sustainable development and win-win results.

[0004] A large number of lighting fixtures are widely distributed in factory production workshops. These lights are continuously turned on during most operating hours to maintain a good working view. However, when the actual working environment has sufficient natural light or specific areas do not require high-intensity lighting, these continuously running lights constitute a significant waste of energy. Utility Model Content

[0005] This utility model aims to provide a lighting control system for factory production workshops. This system addresses the problem of numerous lighting fixtures distributed throughout the factory floor. These fixtures are continuously on during most operating hours to maintain a good working view. However, when the actual working environment is filled with natural light or when specific areas do not require high-intensity lighting, these continuously running fixtures can result in significant energy waste.

[0006] To achieve the above object, the present invention provides the following technical solution: a lighting control system for a factory production workshop, comprising a single-chip microcomputer, wherein a first set of terminals on the single-chip microcomputer is connected to a timer via wires;

[0007] The second group of terminals on the single chip microcomputer is connected to the human body sensor through wires, the third group of terminals on the single chip microcomputer is connected to the voltage regulator through wires, and the output positive pole on the voltage regulator is connected to the lamp.

[0008] As a preferred embodiment of the present invention for a lighting control system applied to a factory production workshop, the clock output pin of the timer is connected to an input pin of a single-chip microcomputer so that the single-chip microcomputer can read the clock signal of the timer.

[0009] As a preferred lighting control system of the present invention applied to a factory production workshop, the VCC of the human body sensor is connected to the positive power supply of the single-chip microcomputer, the GND of the human body sensor is connected to the negative power supply of the single-chip microcomputer, and the OUT of the human body sensor is connected to an input pin of the single-chip microcomputer.

[0010] As a preferred embodiment of the present invention for a lighting control system applied to a factory production workshop, an output pin of the single chip microcomputer is connected to a control signal input pin of a voltage regulator, and a power input pin of the voltage regulator is connected to a power supply of the single chip microcomputer.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Install the MCU, timer, human body sensor, voltage regulator and lamps at the designated location in the factory production workshop. Set the interrupt time of the timer in the MCU to trigger the start and stop of the lamps according to the preset time parameters.

[0013] When the human body sensor detects human activity, it sends an interrupt signal to the MCU. After receiving the interrupt signal, the MCU determines the current status of the lamp. If the lamp is off, it turns on the lamp; if the lamp is already on, it keeps the lamp status unchanged. When the human body sensor does not detect human activity for a period of time, the MCU will delay for a period of time and then turn off the lighting fixture to achieve the purpose of energy saving.

[0014] When the human body sensor detects human activity, the microcontroller determines the distance between the person and the lamp based on the signal strength of the human body sensor. The closer the distance, the brighter the lamp; the farther the distance, the lower the brightness of the lamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 , the utility model provides the following technical solutions: a lighting control system applied to a factory production workshop, comprising a single chip microcomputer 1, a first group of terminals on the single chip microcomputer 1 being connected to a timer 2 via wires;

[0020] The single-chip microcomputer 1 is an STM32 series. As the core of the system, the single-chip microcomputer 1 is responsible for receiving signals from the human body sensor 3, processing the timing tasks of the timer 2, and controlling the voltage regulator 4 to adjust the brightness of the lamp 5.

[0021] The second set of terminals on the single chip computer 1 is connected to the human body sensor 3 through wires, the third set of terminals on the single chip computer 1 is connected to the voltage regulator 4 through wires, and the output positive pole of the voltage regulator 4 is connected to the lamp 5.

[0022] The parts in the above scheme are installed in the factory production workshop when in use. The wiring length between the parts can be set according to the distribution of the installation points in the factory production workshop. In this way, the above system can be installed in the factory production workshop, so that the start and stop and brightness of the on-site lamps 5 can be adjusted at any time according to different areas and situations to achieve energy-saving effects.

[0023] Preferably, the clock output pin of the timer 2 is connected to an input pin of the single chip microcomputer 1 so that the single chip microcomputer 1 can read the clock signal of the timer 2 .

[0024] In specific use, by setting the time parameters of the timer 2, the function of timing start and stop of the lighting fixture 5 can be realized.

[0025] Preferably, the VCC of the human body sensor 3 is connected to the positive power supply of the single chip microcomputer 1 , the GND of the human body sensor 3 is connected to the negative power supply of the single chip microcomputer 1 , and the OUT of the human body sensor 3 is connected to an input pin of the single chip microcomputer 1 .

[0026] In specific use, the model of the human body sensor 3 is HC-SR501. The human body sensor 3 is installed in the area where the light of the lamp 5 needs to be controlled. When human activity is detected, a signal is sent to the microcontroller 1 to trigger the start and stop or brightness adjustment of the lamp 5.

[0027] Preferably, an output pin of the single chip microcomputer 1 is connected to a control signal input pin of the voltage regulator 4 , and a power input pin of the voltage regulator 4 is connected to the power supply of the single chip microcomputer 1 .

[0028] During specific use, the voltage regulator 4 adjusts the terminal voltage of the lamp 5 according to the control signal of the single chip microcomputer 1, thereby achieving brightness adjustment.

[0029] The single-chip computer 1, timer 2, human body sensor 3, voltage regulator 4 and lamp 5 are installed at the designated location in the factory production workshop. The interrupt time of timer 2 is set in the single-chip computer 1, and the lamp 5 is triggered to start and stop according to the preset time parameters.

[0030] When the human body sensor 3 detects human activity, it sends an interrupt signal to the single-chip microcomputer 1. After receiving the interrupt signal, the single-chip microcomputer 1 determines the current state of the lamp 5. If the lamp 5 is in the off state, it turns on the lamp 5; if the lamp 5 is already on, it keeps the lamp 5 in the same state. When the human body sensor 3 does not detect human activity for a period of time, the single-chip microcomputer 1 delays for a period of time and then turns off the lighting lamp 5 to achieve the purpose of energy saving.

[0031] When the human body sensor 3 detects human activity, the single chip 1 determines the distance between the person and the lamp 5 based on the signal strength of the human body sensor 3. The closer the distance, the higher the brightness of the lamp 5; the farther the distance, the lower the brightness of the lamp 5.
