(五） 具体实施方式 (E) the specific embodiments

图1为独立变焦控制原理图，独立变焦控制系统是以人为主要控制器的控制系统。 Figure 1 is a schematic diagram of an independent zoom, zoom control system is based on independent human primary controller of the control system. 由操作者观察镜头变焦位置信息和激光照明器变焦位置信息，以判断现在激光照明器是否处于最佳照明效果，如果现在激光照明器处于最佳照明变焦位置，则保持现在变焦位置不动，否则由操作者控制激光器控制机构，使其达到最佳照明效果。 Lens zoom position information and laser illuminator zoom position information observed by the operator to determine whether it is now the best laser illuminator lighting effects, if now in the best laser illuminator lighting the zoom position, the holding current zoom position does not move, or operator controlled laser control mechanism, to achieve the best lighting effects.

由于人的观察最接近实际使用效果，所以此操作系统的照明效果是最好的。 Since the people closest to the actual observed results, so the lighting effect of this operating system is the best. 但独立控制系统必须由人来控制，镜头变焦位置信息一旦变动，操作者必须实时调整激光器变焦位置。 But independent of the control system must be controlled by the people, the zoom position information once the variation, the operator must adjust the laser zoom position in real time. 对人的依赖使此系统无法脱离人的操作，难以实现实时自动控制。 Dependence on the people to make this system can not operate from the people, it is difficult to achieve real-time automatic control.

图2为同步变焦控制原理图。 Figure 2 is a schematic diagram of synchronous zoom control. 该装置包括两个部分：智能化电路控制部分和具有变焦位置信号反馈的机械传动机构。 The apparatus consists of two parts: the intelligent circuit control section and having a mechanical drive mechanism of the zoom position feedback signal. 本发明的智能化电路控制部分采用通用8位微处理器，配合模数转换芯片和输出驱动芯片，达到智能化处理相关数据和输出控制的目的。 Intelligent circuit control section of the present invention employs a general-purpose 8-bit microprocessor, with the analog to digital converter chip and output driver chip, to achieve intelligent processing purposes related data and output control. 为了增强微处理器工作稳定性和适应不同的镜头，电路中加入了看门狗和串口通讯芯片。 In order to enhance the stability of microprocessor work and adapt to a different lens, adding a watchdog circuit and serial communications chip. 该部分能够接收来自镜头和激光照明器变焦位置的反馈信号，根据预先测量的数据判断镜头和照明器光源的位置差别，自动调整机械传动机构。 The portion is capable of receiving a feedback signal from the laser illuminator and lens zoom position determines the difference between the lens position and the light source device according to the pre-measured data, automatically adjust the mechanical transmission mechanism. 本发明的机械传动机构用来改变激光照明器的照明角度，同时为电路控制部分提供反馈信号。 Mechanical transmission mechanism of the present invention is used to change the lighting angle of the laser illuminator, while providing a feedback signal to the circuit control section. 传动齿轮带动旁边的高精度滑动变阻器，将激光照明器的变焦位置信息转化为电压信号，作为反馈提供给电路控制部分。 Precision gear drive next slide rheostat, the zoom position information of laser illuminator into a voltage signal as a feedback to the circuit control section. 本发明的这两部分是一个有机的整体，共同组成一个闭环反馈结构。 The two parts of the present invention is an organic whole, together form a closed-loop feedback structure. 其中微处理器为控制中心，通过相应软件使激光照明器达到自动同步变焦的目的。 Wherein the microprocessor control center, the laser light through the corresponding software to automatically synchronize zooming reaches purposes.

同步变焦控制系统最大的特点是用微处理器代替人来对整个系统实现自动控制。 The greatest feature of synchronous zoom control system is microprocessor instead of the people of the whole system to achieve automatic control. 系统由微处理器读取镜头变焦位置信息和激光照明器变焦位置信息，通过微处理器内部的既定逻辑来判断照明器是否处于最佳照明变焦位置，如果处于最佳照明变焦位置，则保持控制机构不动，否则微处理器控制激光器控制机构，使激光照明器到达最佳照明变焦位置。 System Lens zoom position information and a laser illuminator zoom position information is read by the microprocessor, established by the internal logic of the microprocessor to determine whether it is the best lighting luminaire zoom position, if in the best light on the zoom position, the holding control mechanism does not move, or the microprocessor controls the laser control mechanism, the laser reaches the optimal lighting illumination zoom position.

微处理器内部的既定逻辑是预先存在微处理器内部的一组数据。 Microprocessor internal logic is established within the microprocessor of a pre-existing set of data.

此数据通过下述方法得到：在微处理器中写入测量程序，手动改变镜头焦距，.同时手动改变激光照明器焦距，直到照明器照明范围与镜头视场范围一致，然后通过计算机串口读取此时的镜头数据和照明器数据，记录下来，依此办法顺序改变镜头焦距，得到一组数据。 This data is obtained by the following method: Write the measurement program, manually change the lens focal length in the microprocessor, while manually changing the focal length of the laser illuminator until lighting Lighting range scope consistent with field lens, and then read by the computer serial port. At this point the lens data and illumination data, recorded, and so a way to change the order of the lens focal length to obtain a set of data. 因此， 微控制器内部的判断逻辑和独立控制系统中操作者的判断逻辑是相同的，所以其控制效果也相同。 Thus, the microcontroller internal decision logic and separate control system operator's judgment logic is the same, so the effect is the same as control. 在保证各部分传动精度的前提下，实际使用效果也是相同的。 In each part of the drive to ensure the accuracy of the premise, the actual effect is the same.
