It is connected with corresponding handheld terminal on full cap and by wired mode, for the audio frequency that will gather
Signal exports to handheld terminal；The plurality of handheld terminal wirelessly with main control server
It is connected；Described audio collecting device includes: audio collection single-chip microcomputer, audio signal sample mould
Block, filtering and noise reduction module, A/D modular converter and communication module；This audio signal sample module,
Filtering and noise reduction module and A/D modular converter are connected in turn, described A/D modular converter
Outfan is connected with audio collection single-chip microcomputer, and the outfan of this audio collection single-chip microcomputer is by logical
Letter module is connected with handheld terminal.
And, described audio collecting device is connected with corresponding handheld terminal by three core tone frequency channel wires
Connect.
And, described handheld terminal includes handheld terminal single-chip microcomputer, wireless WIFI module and report
Alert module；Described handheld terminal single-chip microcomputer is connected with wireless WIFI module and alarm module respectively
Connecing, this handheld terminal single-chip microcomputer is connected with main control server by wireless WIFI module.
Advantage of the present utility model and good effect be:
1, this utility model is by being arranged on the audio collecting device on operation maintenance personnel safety helmet,
Facilitate operation maintenance personnel to gather substation secondary device and run audio signal, and pass through portable hand-held
This audio signal is uploaded to main control server, by main control server by terminal and cordless communication network
This audio signal characteristic amount being contrasted with history audio signal characteristic amount, if finding, relay is protected
The audio signal characteristic amount exception of protection unit or change, then illustrate that this protective relaying device is transported
Row is abnormal, and now, main control server should by the alarm module prompting operation maintenance personnel of handheld terminal
This equipment emphasis is checked.
2, this utility model is by the differentiation to protective relaying device sound, fills relay protection
The running status put is analyzed in real time, beneficially operation maintenance personnel timely discovering device latent defect.
Accompanying drawing explanation
