Below in conjunction with attached drawing, the technical solution of embodiment that the present invention will be described in detail offer.
In a first aspect, the embodiment of the invention provides a kind of coalcutter phonetic alarm devices, and as shown in Fig. 1, the dress
Set includes: power amplifier and loudspeaker.Power amplifier is mounted in coalcutter explosion-proof electric control box, and loudspeaker is mounted on coal mining
On machine explosion-proof electric control box cover board, power amplifier is connected with loudspeaker by cable through walls.
Coalcutter phonetic alarm device provided in an embodiment of the present invention, it is using split-type design, spoilage is lower
Power amplifier is placed in coalcutter explosion-proof electric control box, preferable to the protecting effect of power amplifier.Loudspeaker is mounted on coal mining
On machine explosion-proof electric control box cover board, scene in use, loudspeaker because the factors such as dust and steam damage when, exposed loudspeaker
It is easily changed.Compared with prior art, without opening explosion-proof electric control box, and it need to be only individually replaced loudspeaker, reduces hardware
Maintenance cost reduces labour's consumption.
Optionally, as shown in Fig. 1, coalcutter phonetic alarm device provided in an embodiment of the present invention further includes master control list
Member and control panel, main control unit are connect with control panel, and control panel is connect with power amplifier, and main control unit refers to control panel sending
It enables, control panel sends corresponding audio data to power amplifier according to instruction.
So set, the coalcutter is allow to issue different audios under the instruction of main control unit with phonetic alarm device
Data are alarmed, and warning message diversification, different audio data corresponds to different coalcutter operating conditions, are convenient for staff's root
Current coalcutter operating condition is directly acquired according to audio data, improves working efficiency.
How according to the instruction of main control unit corresponding audio data is sent to power amplifier for control panel, below into
Row illustrates: control board memory contains multiple groups voice data, and multiple groups voice data corresponds to the multiple instruction of main control unit, is used for
Voice data is converted into corresponding audio data under the instruction of main control unit and is sent to power amplifier.
Control panel is previously stored with multiple groups voice data, and establishing has voice data is corresponding with the instruction of main control unit to close
System.After main control unit sends instruction to control panel, voice data corresponding with the instruction is retrieved inside control panel, is converted after calling
At corresponding audio data, audio data is transported to loudspeaker and carries out voice broadcast after power amplifier amplifies.
Optionally, main control unit, control panel and power amplifier pass through CAN (Controller Area Network, control
