摘要
介绍了一种船舶仪表背光照明数字调光器的设计,主要包括MCU微处理器控制模块、控制输出模块、RS485通信模块、输入与显示模块、限流与保护模块等。采用M054微控制器输出脉宽调制(PWM)信号来控制背光照明灯的亮度,实现了PWM全数字调光。经过实船使用测试,该调光器性能优越、可靠性高。
The design of hacklit digital dimmer for a ship insstrment is introduced, mainly including the MCU microprocessor control module, control output module, RS485 communication module, input and display module, current limiting and protecting mochde, etc. M054 microcontroller outputs pulse width modulation （PWM） signal to control the brightness of backlight lamp. And the PWM full digital dimming is achieved. After the ship test, the performance of the dimmer is superior and the reliability is high.
