基于TMS320F2812的测距机电路系统的设计与实现

在传统的激光测距机中，激光发射部分的电源、温控、束散角控制，接收部分的控制、计数、接口等功能，分别采用独立的电路来完成，这使得测距机电路系统和接口关系复杂，也不利于设备的小型化设计。本方案使用TMS320F2812单芯片来实现激光测距机的电子学系统。利用该芯片运行速度快、处理能力强的特性完成测距、温控、控制等功能，并加入各种算法进行数据处理，可有效扩展和提高激光测距机的功能和性能。

Design and implement of laser range finder system based on TMS320F2812

In the development of traditional laser range finder,respective circuitry was made to implement functions such as power supply,temperature control,divergence angle control at transmitter and control,counter,interface at receiver,which made the circuit system and interface complex.In our application,we make laser range finder electronics by using a single device named TMS320F2812 and integrated functions such as range finder,temperature control and motor control etc.into this device.Furthermore,some arithmetic was added to extend the functions and improve the performance of laser range finder.
