针对大型光电项目中并行数据总线长线传输问题，分析了存在问题并给出解决方案。首先介绍了光电系统原有设计方案，以并行接口部分的设计作重点说明，提出错误分析以及解决方案，再针对系统结构采用光电隔离器TLP523-4对原有电路改进，使两设备电气隔离，对传输线进行了“隔离”、“浮地”处理。实验证明改进后的电路，总线驱动能力变强，干扰和畸变得到明显改善，具有较高的实用价值。
- Abstract:
- The long line transmission technology of two-way parallel interface bus of photoelectric equipment is analysed and discussed,and solutions are given.Firstly,the design of the system is introduced, and the two-way parallel interface is explained as an important part, the errors in the system are analysed and two different solutions are given.Then TLP523-4 is applied in the circuit to keep the two parts isolated.An experimental result shows that the new designed photoelectric system has a good performance, which has high value in engineering applications.
