STM32-based broadcast transmitter automatic control system and method

Abstract

The invention discloses an STM32-based broadcast transmitter automatic control system which comprises an STM32 microcontroller, a touch screen unit, a local network server unit, an image acquisition unit and a sampling unit; the STM32 microcontroller is connected with an upper computer, an output port of the STM32 microcontroller is connected with a driving unit, and the driving unit is controlledto execute a control instruction; the touch screen unit is used for displaying processed acquired information and receiving a control instruction of a touch operation; the local network server unit is used for realizing transmitter information remote network display and remote network control; the image acquisition unit is used for regularly acquiring images in a transmitter cabinet for remote observation of maintenance personnel; and the sampling unit is used for calculating control operation which needs to be executed by a transmitter by acquiring transmitter information and controlling thedriving unit to realize automatic control of the transmitter. The system is small in size, rich in hardware resources and high in processing capacity, effective integration of the system is achieved,stability is improved, and cost is reduced. The invention also discloses a method for controlling the transmitter by the system.

Description

technical field [0001] The invention relates to the technical field of broadcast transmitter automatic control, in particular to an STM32-based broadcast transmitter automatic control system and method. Background technique [0002] The automatic control technology of the broadcast transmitter refers to automatically adjusting each component of the transmitter to the corresponding working state according to the currently set working power, working frequency, and on-off time during the working process of the broadcast transmitter. When the upper computer or the touch screen sends a certain control command, the main control board will automatically judge and control the corresponding drive unit to realize the command function according to the collected transmitter status information. At the same time, affected by the use environment and equipment status, it is necessary to collect the incident power, power amplifier voltage, power amplifier current, and fault status data of th...
