Abstract

The invention relates to a method and a device for detecting circuit fault, in particular to a fault self-diagnosis method of a matching network and a device thereof; the method comprises the following steps: transmitting a signal of resonance frequency to a matching network, conveniently, quickly and accurately detecting a fault relay module by comparing voltage amplitude V, voltage amplitude I and phase error phi under three states of initial switch position, switched position and returned initial position of the relay.

Description

technical field [0001] The invention relates to a circuit fault detection method and device, in particular to a matching network fault self-diagnosis method and device. Background technique [0002] Antenna matching network (referred to as matching network) is a matching device for tuning a high-power transmitting antenna, also known as an antenna tuning network. ) to maximize the power transmitted from the transmitter to the antenna. [0003] The composition of the existing matching network is as follows figure 1 As shown, it is mainly composed of a parallel capacitor module 1, a series capacitor module 2, a series inductor module 3 and an antenna capacitor module 4; the parallel capacitor module 1 is composed of a plurality of capacitors C11, C12, ..., C1n connected in parallel Each capacitor is connected to the network through its respective relays K11, K12, ..., K1n in series; the series capacitor module 2 is composed of a plurality of capacitors C21, C22, ..., C2n in ...
