[0024] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0025] A marine industrial control computer that supports multi-mode dimming, such as Figures 1-3 As shown, it includes: an industrial control computer front panel and an industrial control computer motherboard. The industrial control computer front panel and the industrial control computer motherboard are encapsulated in a housing 1. The housing material is such as ABS engineering plastic. The industrial control computer motherboard 7 is installed on the back of the industrial control computer front panel. The industrial control computer front panel is equipped with an industrial control computer display screen 2. The industrial control computer display screen 2 is a common industrial display, such as a common Siemens LED display, Advantech industrial display, etc.

[0026] A dimming button for adjusting the brightness of the industrial computer display screen 2 is provided on the front panel of the industrial computer; specifically, the dimming button is a panel-mount button, including button 5 for increasing brightness and button 6 for decreasing brightness.

[0027] The industrial control computer motherboard 7 is equipped with a dimming knob dimming channel 3, which is used to receive input from an external dimming knob to adjust the brightness of the industrial control computer display screen 2; the dimming knob dimming channel 3 is a 10-position potentiometer screw-type terminal block.

[0028] The industrial control computer motherboard 7 is also equipped with an RS485 serial port dimming channel 4, which is used to receive external serial port dimming signals to adjust the brightness of the industrial control computer display screen 2. The RS485 serial port dimming channel 4 is a screw-clamping terminal block, including at least one of RS485+ terminal block, RS485- terminal block or GND terminal block.

[0029] The industrial computer display screen 2 is connected to a backlight control device. The dimming button is connected to the backlight control device. The industrial computer motherboard is also equipped with a dimming mode switching button 8. The dimming mode switching button 8 is used to switch the connection between the backlight control device and the dimming knob dimming channel 3 or the RS485 serial port dimming channel 4. That is, the dimming button is always connected to the backlight control device, and the dimming knob dimming channel 3 and the RS485 serial port dimming channel 4 can be selected to be connected to the backlight control device. The selection and switching can be made as needed.

[0030] The backlight control device receives analog control signals from the dimming buttons, analog signals from the dimming knob's dimming channel 3, or serial control signals from the RS485 serial port's dimming channel 4 to adjust the brightness of the industrial computer's display screen 2. The brightness adjustment of the industrial control display screen 2 can be achieved through PWM dimming.

[0031] More specifically, the backlight control device includes a data processing module and a dimming control module. The data processing module converts serial port signals and analog signals into PWM signals, and then sends the PWM signals to the dimming control module. The dimming control module realizes the brightness adjustment of the industrial control display screen 2. The dimming control module is an STM32 microcontroller with a PID brightness control algorithm.

[0032] The dimming mode switch button 8 is a self-locking push-button switch. The dimming mode is switched by changing the state of being pressed and released. When the dimming mode switch button 8 is pressed and released, the circuit connection is changed. When pressed, the RS485 serial port dimming channel 4 is disconnected from the backlight control device, and the dimming knob dimming channel 3 is connected to the backlight control device, thereby transmitting the analog signal to the backlight control device and adjusting the brightness of the industrial control display screen through the backlight control device. When released, the dimming knob dimming channel 3 is disconnected from the backlight control device, and the RS485 serial port dimming channel 4 is connected to the backlight control device, thereby transmitting the serial port dimming signal to the backlight control device and adjusting the brightness of the industrial control display screen through the backlight control device.

[0033] Preferably, the industrial control computer is also connected to a centralized dimming device. This centralized dimming device simultaneously connects to the dimming knob dimming channels or RS485 serial port dimming channels of several marine industrial control computers, enabling centralized adjustment of the display brightness of the different marine industrial control computers' screens. The centralized dimming device is either a serial communication device or a dimming knob. When the centralized dimming device is a serial communication device, it connects to RS485 serial port dimming channel 4, inputting serial signals through the centralized dimming device; when the centralized dimming device is a dimming knob, it connects to dimming knob dimming channel 3, inputting analog signals through the centralized dimming device.

[0034] Preferably, the housing also has heat dissipation holes 9 on the back of the industrial control computer motherboard 7 and the industrial control computer display screen 2. The housing has an opening at the lower end of the corresponding industrial control computer motherboard 7, and the dimming knob dimming channel 3, RS485 serial port dimming channel 4 and dimming mode switching button 8 are located below the industrial control computer motherboard 7, with the housing 1 exposed from the opening.

[0035] As a preferred option, corner brackets 10 are also provided on both sides of the back of the housing where the industrial control computer display screen is located. The corner brackets 10 are connected to the housing 1 by bolts. The corner brackets 10 are used to install the industrial control computer on the hull, such as fixing the corner brackets 10 to the desktop, tabletop, control cabinet and other structures by bolts.

[0036] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make non-inventive modifications to this embodiment as needed, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
