Research And Analysis Of The Television Transmitter Supervisory System

This thesis analyzes the composition of television transmitter of the hardware and each part of the software and hardware of television transmitter monitoring system. It makes a primary coverage combing with an analysis about the fault of monitoring system detected in actual work and proposes solutions.Television transmitter is moving intelligent, network-oriented direction, and television transmitter technology is becoming mature. Integrated single-chip technology, computer technology and interface technology monitoring system is widely used in many fieldsTV transmitter monitoring system consists of control unit, actuator control module, power supply and cooling system control module and amplifier data acquisition board. The control unit is the core of the whole control system, which is responsible for directing the work of the various monitoring and control unit. Other functional units have their own test modules, and are responsible for their own data collection transfer, in which the actuator, power supply and cooling system control module also have control function. The monitoring system can not only upload the data of operating status of the machine television transmitter and operating status of the respective constituent units to the monitoring system of monitoring host in engine room and remote telemetry client, but also receive superior instruction sent to the monitoring system. With the use of a transmitter network management system software, monitoring system can automatically make a real-time display of operating state of the transmitter on the remote computer screen and generate data reports, in the meantime, computers also can remotely control the transmitter switch and be set to automatic, etc., which truly realizes unattended.
