Emergency broadcast fault intelligent detection system and working method thereof

Abstract

The invention relates to an emergency broadcast fault intelligent detection system and a working method thereof. The system comprises a cloud server and a broadcast terminal, and the broadcast terminal comprises a communication unit, a data processing unit, a play control unit, an audio output unit and an intelligent detection unit; the data processing unit identifies the type of an instruction, if the instruction is a test broadcast instruction, the intelligent detection unit is activated, and a data processing output signal is generated; the play control unit matches the broadcast content according to the instruction and generates a play control output signal; the audio output unit receives and plays the matched broadcast content and generates an audio output signal; the intelligent detection unit receives the output signals, compares the output signals with corresponding preset signals, outputs state signals of the units according to comparison results, and transmits the state signals to the cloud server through the communication unit. According to the invention, the fault of the emergency broadcast can be precisely positioned, the maintenance efficiency is improved, and the time cost and the labor cost are reduced.

Description

technical field [0001] The invention relates to an emergency broadcasting system, more specifically an emergency broadcasting fault intelligent detection system and a working method thereof. Background technique [0002] When major natural disasters, emergencies, public health and social security and other sudden public crises occur, emergency broadcasting can provide a fast and efficient information transmission channel, and transmit disaster news or possible harm caused by disasters to In the hands of the people, let the people know what happened at the first time, how to evacuate, avoid danger, and minimize the loss of life and property. Due to the particularity of the emergency broadcast, it is rarely used at ordinary times, which makes it impossible to find broadcast faults in time. Manual regular inspections are used, on the one hand, the labor cost is high, on the other hand, it is impossible to confirm where the fault occurred, which makes maintenance inconvenient. ...

Problems solved by technology

Due to the particularity of emergency broadcasting, it is rarely used in normal times, which makes it impossible to find broadcasting faults in time

Regular manual inspection is used, on the one hand, the labor cost is high, on the other hand, it is impossible to confirm where the fault occurred, causing inconvenience in maintenance

[0003] The current broadcasting system can only judge whether the system is normal based on the signal output by the audio output unit. Once a fault is detected, it is not clear whether it is caused by the fault of the audio output unit or the fault of the front playback control unit or data processing unit. It is still necessary for the staff to disassemble and test each module in the system, which is a waste of time and manpower
