Problems solved by technology

[0009] There is basically no off-air alarm equipment in the existing live broadcast room. The early warning and handling of the off-air event mainly rely on the technicians in the main control room of the radio station in a different place. In the event of an emergency, they cannot reach the scene immediately. It takes a certain amount of time to prolong the troubleshooting time, which is not conducive to the safe broadcasting work of radio stations

Embodiment Construction

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0025] see figure 1 As shown, it is a functional schematic diagram of the system implemented by the present invention, and the present invention has three parts:

1. Audio level and threshold level comparison circuit.

[0026] The audio level and threshold level comparison circuit is to collect and quantify the audio signal output by the mixer, calculate the current audio signal level, and compare the audio level value with the preset threshold. If the audio signal level If it is greater than the threshold, it indicates normal broadcasting; if the audio signal level is lower than the thr...

Abstract

The invention belongs to the technical field of broadcast station live broadcast in broadcast television engineering, and particularly relates to a broadcast broadcast stop alarm method for a broadcast station live broadcast room. According to the method, the audio output level of the sound console in the live broadcast room is compared with the threshold level, timing is performed through the low-level timing circuit, and alarm is performed through the alarm circuit. According to the invention, technical support personnel and management personnel can be notified in real time by methods of sound, light, electricity, short messages, WeChat and the like before a broadcast stop event occurs, the speed is high, the alarm is accurate, and the method has a popularization effect on safe broadcast management.

Description

technical field [0001] The invention belongs to the technical field of live broadcast of radio stations in radio and television engineering, and particularly relates to a method for an alarm of broadcast stoppage in a live broadcast room of a radio station. Background technique [0002] During the normal broadcast of the radio station, the mixer in the live broadcast room of the radio station must always maintain a certain volume level of audio output, which is an important prerequisite for the safe broadcast of the broadcast. Caused an outage. [0003] When there is no signal at the output of the mixer or the output level threshold is lower than the set value, this method (or the equipment made by this method) starts timing, and when the time exceeds the set time, an alarm condition is triggered, and the host is reminded in various ways Persons or technical personnel to deal with, to avoid suspension. [0004] For webcasting, it is important to note that: 1) The require...
