The strong electromagnetic interference (EMI) generated in high-power TEA C02 laser system mainly comes from main discharge circuit  pulse spark switch and power supply. Such strong EMI causes great damage and interference to the control system based on DSP. In this paper  we present the interference sources and their distribution and propose the methods of anti-interference. Measures for hardware design include weakening transient ground potential difference by using equipotential lines between devices  using signal isolation interface to inhibit the transient ground potential interference  and rational layout  shielding and filtering to the control system. And methods for software design include range-limited filter  self-diagnosis and self-repair for the critical data and anti-interference during abnormal reset. The EMI has been inhibited effectively by the anti-interference method proposed above. The result shows that: the software anti-interference method is as important as the hardware anti-interference method for the control system in a complex environment of strong EMI. 2010 IEEE.

This paper presents a master-slave multi-communication system designed with several micro-controllers used as master and slave controllers to set signal the lamp to realize point-to-point communication through the RS422 interface. By describing a typical example of this system and the blue print of hardware and the flowchart of software  the reliable work of the system has been proved. The circuits of system are very simple and practical  and they can be used to realize all the functions of a pilotless airborne mapping equipment. It also has a strong anti-jamming capability due to its balanced transfer scheme with single transmitter and multiple receivers. It is very efficient in protecting the integrity and correctness of transmitted and received signals  avoiding the collision of signals through the bus  satisfying the communication among several micro-controllers in a single system and forming a special communication network. 2009 SPIE.

In order to make photoelectric encoder usable in a spaceflight camera which adopts CAN bus as the communication method  CAN bus interface of the photoelectric encoder is designed in this paper. CAN bus interface hardware circuit of photoelectric encoder consists of CAN bus controller SJA 1000  CAN bus transceiver TJA1050 and singlechip. CAN bus interface controlling software program is completed in C language. A ten-meter shield twisted pair line is used as the transmission medium in the spaceflight camera  and speed rate is 600kbps.The experiments show that: the photoelectric encoder with CAN bus interface which has the advantages of more reliability  real-time  transfer rate and transfer distance overcomes communication line's shortcomings of classical photoelectric encoder system. The system works well in automatic measuring and controlling system. 2009 SPIE.
