Abstract

The design method of electromagnetic compatibility of the vehicular optic-electronic equipment and corresponding electromagnetic anti-interference measures were proposed to improve its electromagnetic interference ability and operating reliability at the complicated electromagnetic environment. The components were introduced based on the vehicular opto-electronic equipment in this paper. At the same time

the electromagnetic compatibilities of the mechanism and electricity were designed

including opto-electronic equipment and the shielding shelter. To overcome the electromagnetic interference between wires in interconnect cables

the electromagnetic anti-inference measures

such as the cable choice

cable layout and earthing mode were introduced emphatically. According to the characters of weak electromagnetic interference resistance in the poor electromagnetic environment

the specific settlement measures were proposed in detail. Finally

the design method of electromagnetic compatibility was discussed as well. The tests were performed at an electromagnetic environment of RE102(10 kHz-18 GHz field radiation). Experimental results indicate that the vehicular opto-electronic equipment can work successfully and reliably in this condition above mentioned. It provides important design methods of the electromagnetic compatibility for the kindred opto-electronic equipment and can satisfy the system requirements of strong anti-jamming and stabilization.
