Keywords: radio and television signal transmission; Launch; The problem of safe broadcasting: When broadcasting radio and television programs, one of the indispensable tasks is to ensure the signal safety. Therefore, relevant personnel should do this work well and control the safe transmission of signals. This paper discusses this issue.
1 Factors affecting the safe broadcasting of TV signals
First, generally speaking, major technical accidents are an important factor affecting the safe broadcast of TV signals. In order to ensure the safe broadcast, it is necessary to ensure the smooth launch and signal transmission. Because the scale of broadcasting and television system is very large and there are many complicated details, it is impossible to achieve comprehensive management, and there will inevitably be loopholes. In addition, due to the widespread popularity of network information technology, it is easy to affect the links of radio and television media, thus affecting the operation of programs. Secondly, man-made destruction is also an extremely important reason. In order to ensure the safe broadcasting of radio and television, measures should be taken to prevent network attacks and man-made sabotage, and to prevent signal damage. Third, disasters of major nature, such as terrorist attacks and fires, geological disasters, natural disasters and other disasters that cannot be recovered in a short period of time, belong to major disasters.
2. Control the safe transmission and transmission of radio and television signals.
2. 1 Ensure the overall level and quality of personnel.
In essence, people are an extremely important factor in broadcasting radio and television signals safely. Whether operating equipment, managing equipment or maintaining equipment, it is inseparable from the cooperation of people. Due to the gradual development of science and technology in China, researchers are studying more and more advanced technologies, so they are required to have solid professional knowledge and excellent basic theories. In addition to mastering the operation flow and process of transmitting signals, it is also necessary to understand the performance of information transmitting equipment and the procedures, laws and principles of operating signal transmitting equipment. In addition, you should also have the skills to judge and deal with faults, so as to deal with faults in the first time [1]. In practical work, it is necessary to strengthen the control and management of relevant personnel, and at the same time implement targeted training to enable them to perform multiple tasks in accordance with relevant rules and regulations, and pay great attention to it in practice to prevent unnecessary losses caused by negligence affecting safe broadcasting [2].
2.2 Clear job responsibilities
Safe broadcasting is an important goal of TV signal transmission, which covers many contents, including equipment safety, personal safety and political safety of computer room. In order to prevent the program from stopping or broadcasting badly, managers should formulate the handover system, duty system, maintenance system and safety system of this work, and ensure the orderly development of all work through the system. From a certain point of view, this work can be divided into broadcast system and power system, antenna system and program transmission system. It is worth noting that in order to implement everyone's responsibilities, only in this way can relevant personnel clearly understand their responsibilities in specific work, fully mobilize their enthusiasm, actively carry out related work, and ensure better and smoother program broadcasting.
2.3 purchase of equipment
From a certain point of view, equipment selection is an essential procedure for the safe transmission and transmission of radio and television signals. In order to better manage equipment, it is necessary to purchase equipment scientifically, taking into account the advanced technology and economic rationality [4]. For example, when selecting the transmitter for power supply and distribution, after determining the power level and frequency level, we should consider the technical performance and operation status of the transmitter, after-sales service and so on. In practice, it is extremely difficult to raise funds for the launch pad, and it usually takes a long time to replace the launch pad. Therefore, when purchasing equipment, we should not only ensure reliability and safety, but also comprehensively consider maintainability, cost performance and advancement to prevent avoidable losses caused by omissions [5].
2.4 Intensify equipment renewal and maintenance.
In the actual transmission of radio and television signals, it is often necessary to apply various devices, especially transmitting stations. From a certain point of view, the transmitting station can ensure more stable signal transmission and smoother broadcast of radio and television programs. In order to keep the transmitter in the best working condition, relevant personnel should do a good job of patrol and other related work when on duty, specifically in the following aspects. Touch the temperature of the equipment first, listen to the sound of the equipment, and observe the external and internal structure of the equipment. Second, the equipment should be overhauled regularly. As a person who overhauls equipment, he should not only master the working principle, characteristics and performance of the equipment, but also master the technical parameters of the equipment, so as to find the abnormal working state of the equipment in time, so as to deal with it in time and ensure the normal and safe operation of the equipment [6].
2.5 Ensure the standardized operation of broadcasting equipment.
From a certain point of view, in order to ensure the safe broadcast of signals, an essential link is standardized equipment operation, and the following points should be achieved: First, the inspection of TV signals and FM status should be intensified 30 minutes before the broadcast of the program, and once problems are found, they should be dealt with as soon as possible to prevent the normal broadcast of the program from being affected. Secondly, you can set the automatic start time and shutdown time of the transmitter with the help of the system application. On this basis, the personnel on duty should repeatedly confirm the transmitter status and broadcasting situation. Thirdly, if you don't need to use the transmitter, you should set the automatic shutdown state, and only in special circumstances can you use the manual on-off mode. Fourth, when cleaning the desk lamp equipment and transmitter, it is necessary to prevent the equipment from being in working condition because of touching its switch. Finally, if the transmitter is working and suddenly fails, it should be switched to the standby machine at the first time to prevent the normal program broadcast from being affected, and at the same time, the main machine failure should be handled as soon as possible.
2.6 Intensify efforts to deal with broadcasting equipment failures.
No matter what kind of equipment, it has its own service life. After running for a period of time, it is inevitable that there will be failures. Something happened at work, so calm down first. If the staff lacks experience and excellent psychological quality, it will cause panic after failure, which will not only lead to the time of failure, but also lead to greater failure. Therefore, it is necessary to cultivate the psychological quality of staff in daily life, so that when a fault occurs, it can be judged more accurately and effective measures can be taken to deal with it correctly. If the situation is extremely serious, when taking measures to deal with the fault, the personnel on duty should also report the fault to the superior leader at the same time, so as to ensure that the losses caused by the equipment fault can be minimized through the efforts of all parties.
3 Conclusion
Accidents often occur during the broadcast of radio and television programs, which are generally caused by problems related to signal transmission and transmission. At the same time, many reasons will cause problems in signal transmission and transmission. Therefore, in order to avoid broadcasting accidents to the greatest extent, it is necessary to eliminate related factors that may have an impact. In addition, it is necessary to strengthen the training of personnel, so that they can master certain knowledge and have excellent professional quality, so as to take the initiative to deal with and deal with accidents, thus ensuring the smooth transmission and transmission of signals, and then ensuring the smooth broadcast of radio and television programs.
