实施例二：Embodiment two:
附图5为实施例二示出的星模拟器的光源控制方法的实现流程图。实施例二示出的星模拟器的光源控制方法适用于星模拟器的光源控制模块，光源控制模块中设置处理器，以控制星模拟器中光源发光状态。为了便于说明，仅示出了与本发明实施例相关的部分，详述如下：Accompanying drawing 5 is the implementation flowchart of the light source control method of the star simulator shown in the second embodiment. The light source control method of the star simulator shown in the second embodiment is applicable to the light source control module of the star simulator, and a processor is set in the light source control module to control the light emitting state of the light source in the star simulator. For ease of description, only the parts related to the embodiments of the present invention are shown, and the details are as follows:
步骤S110，脉宽调制模块通过通信电路模组接收上位机软件发送的通信信号指令，并发送给主控芯片电路模组。Step S110, the pulse width modulation module receives the communication signal command sent by the upper computer software through the communication circuit module, and sends it to the main control chip circuit module.
步骤S120，所述主控芯片电路模组将所述通信信号指令调制生成相应的脉冲调制方波。Step S120, the main control chip circuit module modulates the communication signal instruction to generate a corresponding pulse modulation square wave.
步骤S130，根据所述脉冲调制方波，驱动模块生成相应的驱动信号，对安装在光源安装模块上的多个光源进行独立控制。Step S130, according to the pulse modulation square wave, the driving module generates a corresponding driving signal to independently control the multiple light sources installed on the light source installation module.
光源控制模块对光源进行具体控制的方式在实施例一中已有描述，在此不再赘述。The manner in which the light source control module controls the light source has been described in Embodiment 1, and will not be repeated here.
整个光源控制模块实现了在线调整光源输出的功能，当接收上位机控制信号指令后输出的脉宽调制方波的频率远高于采集传感器的采集频率时，从宏观上观察到的光源实际是常亮的状态，当方波的占空比越高时，光源越亮；占空比越低时，光源越暗。The entire light source control module realizes the function of adjusting the output of the light source online. When the frequency of the pulse width modulated square wave output after receiving the control signal command from the host computer is much higher than the acquisition frequency of the acquisition sensor, the light source observed macroscopically is actually normal. In the bright state, the higher the duty cycle of the square wave, the brighter the light source; the lower the duty cycle, the darker the light source.
需要说明的是，外部设备可以手机、电脑等智能设备，使用户能轻易对星模拟器的各个光源进行独立控制，有效实现改变星模拟器中不同位置星点的亮度值，大大提高了对星模拟器中光源控制的精度和灵活性。It should be noted that the external devices can be mobile phones, computers and other smart devices, so that users can easily independently control each light source of the star simulator, and effectively change the brightness value of star points at different positions in the star simulator, which greatly improves the accuracy of the star simulator. Precision and flexibility in light source control in the simulator.
