At present, solid-state transmitters are the most basic form of communication in the process of digital information transmission, with characteristics such as relevance, diversity, and adaptability. This article starts from the background of the application of radio and television technology, combined with the principles of radio and television solid-state transmitters, and conducts an in-depth discussion on the problems and maintenance strategies of radio and television solid-state transmitters, hoping to maximize the advantages of equipment and technology to ensure radio and television The broadcast quality of the program.
Relying on the transmission of radio and television signals, it can ensure the comprehensive exploration and communication of social information, which can be said to be the main link of the entire social information communication. With the rapid development of social economy, my country's media industry has ushered in unprecedented development opportunities, especially the transmission methods of radio and television information will face various demands for self-optimization, development, and update. At this stage, the main technical form of my country's radio and television is a solid-state transmitter, which allows signal transmission modes to be conducted in multiple dimensions, and is directly related to the quality of radio and television programs. Therefore, it is of practical significance to discuss the principles and maintenance strategies of radio and television solid-state transmitters.
1. Analysis on the principle of radio and television solid-state transmitters
Intuitively speaking, a solid-state transmitter is an information control device, which contains dozens or even thousands of solid-state transmitter modules. On the one hand, the program of the solid-state transmitter mainly relies on the microwave integrated circuit, so that several solid-state transmitting modules are "series" together, so that the goal of comprehensively regulating the solid-state transmitting frequency can be further achieved in a specific period; the other is On the one hand, in the process of transmitting and receiving microwaves, solid-state transmitters mainly rely on several microwave power devices, or with the help of low-noise receiver guides. The specific analysis is as follows:
(1) Analysis on the principle of hardware control
From the perspective of my country's radio and television technology system, the current solid-state transmitter structure mainly includes computer monitoring systems, cold air systems, power supply control systems, passive components, power methods, exciters, and so on. In terms of power exciter, its main function is to undertake the important task of signal transmission and reception of solid-state transmitters; for passive components and power methods, its function is to scientifically process and regulate power; computer monitoring system, cold air The main functions of the system and the entire power supply control structure are to supervise the operating status of the entire system and be responsible for the processing of frequency signals, namely: according to the different requirements of different programs, so as to achieve the goal of controlling the microcontroller and power conditions under the control of the main control system .
(2) Analysis on the principle of program control
Intuitively speaking, the radio and television solid-state transmitter system is actually a structure that can comprehensively adjust the program. First, the solid-state transmitter uses a 550W power transmission system as a carrier to adjust the frequency of the synthesized signal structure to 4×2. The signal transmitted from this is relatively stable and has multiple characteristics; second, in terms of the power connection mode of this technology, it is an applied power management structure, and the corresponding power is set in the program. The amplifying unit helps to strengthen the signal strength, thereby ensuring the quality of signal transmission and reception. Third, with the support of the power 20% synthesizer and the balanced amplifier, the power efficiency adjustment ability can be improved; at the same time, relying on the automatic conversion process, it can maximize the guarantee that there will be no signal transmission failures and other problems during the signal transmission process.
