BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 Schematic diagram of a foggy weather lighting control system for construction machinery according to an embodiment of the present invention. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example

[0018] This embodiment provides a foggy lighting control system for construction machinery, such as Figure 1As shown, it includes a lighting unit, and its lighting light includes white light and yellow light. A mode setting unit is connected to the controller, used to display and switch the working mode of the lighting unit, and send different working mode signals to the controller; wherein the working mode of the lighting unit includes fog light automatic mode, fog light manual mode, and brightness automatic adjustment mode. The controller is connected to the switch operation unit and the mode setting unit, and is used to send adjustment instructions to the switch operation unit according to different working mode signals. The switch operation unit is connected to the lighting unit, the controller and the mode setting unit, and is used to monitor the current lighting light color and send it to the mode setting unit, control the switch of the lighting unit, and adjust the lighting light color and brightness according to the adjustment instructions of the controller. The light sensor is connected to the mode setting unit, and is used to detect the brightness value of the surrounding environment and send it to the mode setting unit; the mode setting unit sends the brightness value of the surrounding environment to the controller. The visibility sensor is connected to the controller, and is used to detect the visibility value of the surrounding environment and send it to the controller. The vehicle-mounted terminal device is connected to a mode setting unit and is used to send current weather information to the mode setting unit so as to prompt the driver to adjust the lighting unit through the mode setting unit to prevent the driver from turning on or switching the lights untimely.

[0019] Furthermore, the lighting unit includes a first lighting lamp, a first relay, a second lighting lamp, and a second relay. The first lighting lamp, the first relay, and the switch operation unit are connected in sequence, and the switch operation unit controls the first lighting lamp on and off and adjusts the color and brightness of the lighting light by controlling the action of the first relay. The second lighting lamp, the second relay, and the switch operation unit are connected in sequence, and the switch operation unit controls the second lighting lamp on and off and adjusts the color and brightness of the lighting light by controlling the action of the second relay.

[0020] Furthermore, when the first and second lighting lamps are turned on, the lighting light is white light, and if the switch operation unit is operated once within a set time, the lighting light is switched to yellow light, and the cycle is repeated in sequence. The white light is used for nighttime lighting, and the yellow light is used for foggy lighting.

[0021] In this embodiment, the first lighting lamp and the second lighting lamp have three lighting states: off, white light and yellow light. When the current lighting lamp is off, the switch operation unit executes an on instruction to switch to white light, and executes three actions of on-off-on to switch to yellow light. When the current lighting lamp is white light, the switch operation unit executes two actions of off-on to switch to yellow light. When the current lighting lamp is yellow light, the switch operation unit executes off-on to switch to white light.

[0022] The mode setting unit includes a display screen, which is used to display the current working mode of the lighting unit, and the driver switches the working mode of the lighting unit through the display screen. The driver can switch the working mode of the lighting unit by operating a virtual button on the display screen.

[0023] Furthermore, the mode setting unit is also used to display and switch the lighting color. The display screen is used to display the current lighting color. The driver switches the lighting color by operating the virtual button on the display screen. The display screen sends the color switching information to the controller to achieve one-key switching of the lighting color, which is easy to operate.

[0024] Furthermore, the switch operation unit sends the monitored current lighting color to the mode setting unit, which is displayed on the display screen to remind the driver of the current lighting status. When the current lighting is off, the display icon is gray, when the current lighting is in white light mode, the display icon is white, and when the current lighting is yellow, the display icon is yellow.

[0025] The manual mode of the fog lamp includes a synchronous control mode of the lighting lamp and an asynchronous control mode of the lighting lamp. When the mode setting unit displays the synchronous control mode of the lighting lamp, the driver operates the switch operation unit to control the switches of the first lighting lamp and the second lighting lamp at the same time. When the mode setting unit displays the asynchronous control mode of the lighting lamp, the driver operates the switch operation unit, and the first lighting lamp and the second lighting lamp are turned on in sequence. In this embodiment, when in the asynchronous control mode of the lighting lamp, the switch operation unit is operated, the first lighting lamp is turned on, and the first lighting lamp and the second lighting lamp are turned on at the same time by pressing again, and the first lighting lamp and the second lighting lamp are turned off at the same time by pressing again. Example

[0026] This embodiment provides a control method based on Embodiment 1. Specifically, it includes: Obtain the current operating mode of the lighting unit.

[0027] If the lighting unit is in the fog light automatic mode, determine whether the current surrounding visibility value is less than the set value; if it is less than the set value, and the switch operation unit monitors that the current lighting light color is white, send a yellow light execution instruction to the switch operation unit; otherwise, do not send the instruction.

[0028] If the lighting unit is in the manual control mode, the driver operates the switch operating unit to control the switch of the lighting unit and adjust the color of the lighting light.

[0029] If the lighting unit is in the automatic brightness adjustment mode, determine whether the current ambient brightness value is less than the set value; if so, send a brightness adjustment instruction to the switch operation unit to adjust the lighting brightness of the lighting unit; otherwise, do not send an instruction.
