CAN总线技术在激光测距机中的应用

Application of CAN Field BUS Technology in Laser Rangefinder

随着激光技术的发展，针对激光测距机各分机之间的实时双向通讯的需求，提出采用CAN总线的方式实现。在具体的电路设计中，从高性能和实用性的角度出发，围绕LPC2119做控制器，开发了一种基于CAN总线通讯的脉冲激光测距机系统。通过实践证明该系统运行稳定可靠，达到了设计要求。

With the development of laser technologies, towards the requirements of real - time two way communications between the sub - systems of the laser range finder, the implement method with CAN bus is presented in this paper. In practical circuit design, from high performance and practicability point of view, centered on the LPC2119 micro controller a pulsed laser range finder based on CAN bus communication is developed. This system has proven stable and reliable in operation. The design requirement has been achieved.
