Abstract

The invention discloses a method for measuring the electromagnetic compatibility between a receiving device and a transmitting device based on a geographical information system, and belongs to the technical field of electromagnetic compatibility measurement. According to the method, signals transmitted by the transmitting device are received through a direct injection method or a radiation method, playback monitoring is conducted on the transmitted signals after radio wave propagation path loss calculation and correction, the transmitted signals are sent to the receiving device through the direct injection method or the radiation method after being played back, and then the electromagnetic compatibility measurement is conducted on the transmitted signals. According to the method, the calculation result of a real interference signal, the calculation result of the receiving device and the calculation result of an electromagnetic compatible and coupling path are combined so that the electromagnetic compatibility of the receiving device and the transmitting device can be evaluated, the measurement procedure is simplified, the measurement difficulty is lowered, the measurement expenses are reduced, and compared with traditional electromagnetic compatibility forecasting and simulation, the electromagnetic compatibility forecasting and the simulation have the advantages that the result is closer to the real condition and the accuracy is higher.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic compatibility testing, and relates to an electromagnetic compatibility measurement system between transceiver devices based on a geographic information system. and systems for evaluating the electromagnetic compatibility of transceiver equipment. Background technique [0002] The rapid development of wireless communication technology makes electromagnetic interference signals highly dense in a limited space, and the electromagnetic environment becomes very complicated. How to accurately evaluate the electromagnetic compatibility between transceiver equipment in a local area is a hot and difficult point in the development of electromagnetic compatibility. The EMC evaluation methods between transceiver devices at this stage include prediction methods and measurement methods. The former can only obtain theoretical EMC results, and there may be a large error with the actual results. The latte...
