Problems solved by technology

At present, the signal acquisition of the traditional short-wave transmitter measurement device still uses a single-chip microcomputer as the main control chip. There is no display interface and no data storage function. The record of the electrical parameters of the transmitter can only be recorded manually, and it is impossible to unify the electrical parameters of the transmitter. Management and Analysis
Since there is no human-machine interface, another industrial computer needs to be used to correct the collected parameter values. There is no network port, and the remote maintenance of the monitoring device cannot be performed. The software upgrade can no longer adapt to the current development.

Abstract

The invention provides an ARM-based 150 kW short-wave transmitter monitoring system. The monitoring system has the functions of measurement for the electrical signals of a 150 kW short-wave transmitter, temperature measurement, amplitude modulation measurement, interface display, data storage, serial communications, network communications or the like. The system processes and analyzes all the monitoring data of the 150 kW short-wave transmitter to judge whether the overall working state of the transmitter is normal or not. Meanwhile, the system realizes the functions of automatic meter reading, automatic detection, automatic diagnosis, ultra-threshold alarm, data query, WIFI and so on.

Description

technical field [0001] The invention relates to data collection and monitoring of electrical parameters of a short-wave transmitter, in particular to a monitoring system for a short-wave transmitter based on an embedded system. Background technique [0002] The 150kW short-wave transmitter monitoring system mainly realizes the real-time monitoring and data detection of the working status of the 150kW short-wave transmitter and the electrical parameters of the circuits at all levels. At present, the signal acquisition of the traditional short-wave transmitter measurement device still uses a single-chip microcomputer as the main control chip. There is no display interface and no data storage function. The record of the electrical parameters of the transmitter can only be recorded manually, and it is impossible to unify the electrical parameters of the transmitter. management and analysis. Since there is no human-machine interface, another industrial computer needs to be used ...
