Automatic debugging method and system for cavity filter

Abstract

The invention relates to an automatic debugging method and a system for cavity filter. The method comprises: correcting the coordinate system of a cavity filter engineering design file; determining the X and Y coordinate position information of the engineering file and the corresponding X and Y coordinate position information of a debugging platform; accessing the preset Z coordinate height recording file; obtaining the preset height information of all cavity filter regulation screws; adjusting all the regulation screws to the preset positions corresponding to the preset height information; adjusting the regulation screws upwards and downwards in the Z coordinate direction at the preset position height; through the network based analyzing instrument, monitoring in real time the performances and the change information of the cavity filter and transmitting the monitored performances and the change information to a control device; analyzing by the control device the real-time performance change information; determining the determined debugging positions of the regulation screws; and according to the height information of the determined debugging positions, updating the preset height position information. The method and the system of the invention are highly automatic and can obviously increase the debugging efficiency and the working efficiency, therefore, making the method and the system of obvious advantage in cost and production.

Description

technical field [0001] The invention relates to debugging equipment, and more particularly, to a method and system for automatic debugging of cavity filters. Background technique [0002] As an indispensable frequency selection device, the filter is the key equipment of the modern mobile communication system, as well as the essential equipment for the wireless communication base station and signal coverage. The performance of the filter directly affects the quality of the entire system. The cavity filter has excellent performance such as large power capacity, high stopband rejection, frequency bandwidth, flatness in the passband, small group delay and excessive band narrowing. Therefore, the combiner with cavity filter technology as the core, frequency division Filters, band-pass, band-stop, high-pass, and low-pass filters are widely used in modern mobile communication systems. [0003] like figure 1 As shown, the cavity filter generally includes an open mouth body 101 , a...

Problems solved by technology

Therefore, the debugging of the cavity filter is complicated and heavy. Only experienced workers who have been fully trained can complete the complex debugging of the cavity filter and realize the performance of the cavity filter. Moreover, in the actual mass production of the cavity filter Among them, due to the influence of error factors such as production and assembly, each cavity filter must be fully debugged by skilled workers to achieve performance. The resulting cost and production bottlenecks have always been a huge obstacle to the scale development of cavity filters.
