Multifunctional belt early-warning automatic broadcast-expanding switching device

Abstract

The invention discloses a multifunctional belt early-warning automatic broadcast-expanding switching device. The device is used for solving the problem that an existing broadcast switching device cannot automatically adjust the ringing sound of the device according to a use scene and inconvenience of use is caused; the system comprises an automatic broadcast switching device, a computer, a networkconversion module and a plurality of amplified phones installed in a belt lane; the automatic broadcast switching device comprises a broadcast switching device host and a broadcast phone board installed in the broadcast switching device host; via the device disclosed in the invention, the connection duration and the automatic answering frequency of the amplified phone are analyzed and the phone amplification value of the amplified phone is obtained by using a formula; the corresponding execution instruction is obtained by judging the telephone sound amplification value, and the sound amplification amount of the sound amplification telephone is controlled according to the execution instruction, so that the sound amplification amount of the sound amplification telephone is reasonably improved, and a worker in the belt lane can hear the ringing sound of the sound amplification telephone in time.

Description

technical field [0001] The invention relates to the technical field of emergency broadcasting, in particular to a multi-functional belt pre-warning automatic broadcasting adapter device. Background technique [0002] The main unit of the expansion automatic switching device can realize the automatic connection between the dispatching telephone system and the expansion telephone system. Its purpose is mainly to solve the emergency broadcasting of fully mechanized mining and belt lanes, and to facilitate finding people. It is also an extension and extension of the end of the broadcast rescue system. At the same time, the secondary use of fully mechanized mining and belt amplified telephones saves costs. [0003] The expansion automatic transfer device can be installed in the inclined roadway of the belt, along the transportation line of the waiting car, and on the working face. Call the dispatching room, and the dispatching room realizes emergency broadcasting to help miners ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing broadcast expansion adapter device cannot automatically adjust the volume of the ringing sound of the device according to the usage scene, resulting in inconvenient use, and proposes a multifunctional belt early warning automatic broadcast expansion adapter device; The invention analyzes the connection time of the amplified telephone and the number of times of automatic answering and uses the formula to obtain the telephone amplified value of the amplified telephone, obtains the corresponding execution instruction by judging the amplified value of the telephone, and controls the amplified telephone according to the execution instruction The amplified volume, so as to reasonably increase the amplified volume of the amplified telephone, so that the staff inside the belt alley can hear the ringing sound of the amplified telephone in time;
