Problems solved by technology

At present, the standing wave ratio is measured and optimized by the broadcast transmitter in the transmission time slot, but although this method improves the measurement accuracy to a certain extent, the hardware is still implemented in an analog way, which is simple to implement and ignores real-time sexual demands
[0004] Therefore, the current standing wave ratio measurement method of broadcasting transmitters has the disadvantages of unreasonable design and inability to meet real-time requirements

Abstract

The invention provides a method and a system for measuring the standing-wave ratio of a broadcast transmitter. The method comprises the following steps: S1, acquiring acquired data; s2, analyzing and processing the collected data to obtain first analysis data; s3, comparing the first analysis data with a trigger threshold value; when the first analysis data is within the trigger threshold value, performing transient voltage standing wave ratio calculation on the first analysis data to obtain first calculation data; s4, comparing the first calculation data with a preset threshold value; when the first calculation data is within the preset threshold range, performing high-precision standing-wave ratio calculation on the first calculation data to obtain second calculation data; and S5, analyzing and calculating the second calculation data to obtain the standing-wave ratio of the broadcast transmitter. The method has the advantages that the design is reasonable, the standing-wave ratio of the broadcast transmitter can be accurately measured in real time, and the measurement precision is high.

Description

technical field [0001] The invention belongs to the technical field of radio and television transmitter testing, and in particular relates to a method, a system, an electronic device and a storage medium for measuring the standing wave ratio of a radio transmitter. Background technique [0002] An important core component of a broadcast transmitter is a high-power vacuum tube, which has the characteristics of large size, high power consumption, high heat generation, short life, high power supply voltage, fragile structure and low power supply utilization. Compared with other components such as modern electronic tubes, high-power vacuum tubes have the characteristics of high power, high gain, wide frequency, high reliability, strong load capacity, excellent linear performance, and are very suitable for working in high-power fields, making them suitable for broadcast transmission. Machines and other equipment continue to play an irreplaceable role. [0003] The measurement of...
