Equipment layout regulating method on basis of exposure measurement on microwave frequency band radiation

Abstract

The invention discloses an equipment layout regulating method on the basis of exposure measurement on microwave frequency band radiation. According to the method, by measuring microwave frequency band radiation intensity of airborne equipment in different regions of a helicopter cabin body, combining a military standard limit and adopting a weighting matrix strategy, calculation on the electromagnetic compatibility balance degree of the complete machine microwave frequency band radiation of a helicopter system is completed and the problems that conventionally, an electromagnetic compatibility balanced state of the equipment radiation in the microwave frequency band of the system is difficult to well track and monitor and improvement potential of the electromagnetic compatibility of the system cannot be judged are solved. By considering the radiation characteristics of the complete machine microwave frequency band of the helicopter system, the electromagnetic compatibility balanced state of the complete machine microwave frequency band of the helicopter system is evaluated, so that pertinence and effectiveness of quantitative evaluation on the electromagnetic compatibility of the microwave frequency range are improved.

Description

technical field [0001] The invention relates to an equipment layout adjustment method based on microwave frequency band radiation exposure measurement, and belongs to the field of electromagnetic compatibility design. Background technique [0002] In electronic and electrical systems where multiple devices work together, the electromagnetic interference generated by a certain device will be coupled to another device through conduction emission and radiation emission, causing the performance of the other device to degrade or even fail to work normally. With the increasing precision of integrated circuits and the increasing complexity of system equipment, the system's requirements for electromagnetic compatibility have been widely concerned by people. [0003] In the later stage of the design and manufacture of the helicopter system, various EMC standards tests will be carried out on the whole machine to show that the EMC performance of the whole machine is qualified when the ...

AI Technical Summary

Problems solved by technology

[0003] In the late stage of design and manufacture of the helicopter system, various EMC standards tests will be carried out on the whole machine to show that the EMC performance of the whole machine is qualified when the airborne equipment is installed. At this time, many airborne equipment have been designed and finalized. It is difficult and costly to rectify the electromagnetic compatibility problems that arise

However, from the helicopter program stage to the engineering development stage, effective and real-time control methods for the radiation electromagnetic compatibility of airborne equipment are limited, and there is no clear and quantified radiation electromagnetic compatibility balance standard, which makes it difficult to achieve the monitoring purpose in the electromagnetic compatibility process control
