Dual-frequency synchronous dynamic monitoring short message alarm for broadcast transmitters

Abstract

The invention discloses a dual-frequency synchronous dynamic monitoring short message alarm for broadcast transmitters. The alarm comprises a signal receiving module, a logic processing module, a central processing module, a short message alarm module and a power source module; the logic processing module comprises an audio amplification and delay device, a clock timer and four comparators. With the alarm of the invention adopted, the synchronous monitoring of the working states of a plurality of broadcast transmitters, the initial classification of the operating states and accidents of the transmitters, short message accurate alarm, simple and convenient maintenance can be realized; remote monitoring by engineering technicians can be realized; the dynamic conditions of a machine room canbe mastered at any time; accident handling efficiency can be improved; the safe and high quality broadcasting of broadcast programs can be ensured; and effective technical supervision on the working states of the broadcast transmitters of unattended broadcast transmitting stations can be implemented in particular.

Description

technical field [0001] The invention relates to a broadcast transmitter, in particular to a dual-frequency synchronous dynamic monitoring short message alarm for the broadcast transmitter. Background technique [0002] With the continuous advancement of broadcasting technology, the automation level of broadcasting transmitters is getting higher and higher, and the requirements for the detection and alarm system are higher. The multi-function and reliability of detection equipment is the key to ensure the safe and high-quality broadcasting of broadcasting programs. [0003] At present, the most common and practical monitoring equipment for broadcast transmitters basically only has the function of loop monitoring. A few equipment have sound and light alarm function, poor stability, high false alarm rate, difficult maintenance of integrated design, no professional SMS alarm function, when the staff leave Posts or computer rooms cannot seamlessly monitor the working status of th...

Problems solved by technology

[0003] At present, the most common and practical monitoring equipment for broadcast transmitters basically only has the function of loop monitoring. A few equipment have sound and light alarm function, poor stability, high false alarm rate, difficult maintenance of integrated design, no professional SMS alarm function, when the staff leave Posts or computer rooms cannot seamlessly monitor the working status of the transmitter

The disadvantage of loop monitoring is that when the monitoring time of a single channel is prolonged, the entire cycle time will be extended. When a channel fails, it cannot be found in time, slowing down the alarm speed, and synchronous monitoring of multiple transmitters cannot be performed; the length of audio signal interruption cannot be determined. Judgment, leading to misjudgment and false alarms in special programs, such as: live broadcast or major event programs, such programs have slow broadcasting speed and long pause time

When a broadcast accident occurs, the scope of the fault cannot be judged in time, especially in the unattended computer room, which cannot realize the constant monitoring of the working status of the transmitter in the computer room

However, multi-functional large-scale monitoring equipment is expensive, and broadcasting stations at and below the county level do not have the financial ability to purchase
