Abstract
The utility model relates to a mining intrinsic safety type reversing alarm. The mining intrinsic safety type reversing alarm comprises a shell, a loudspeaker arranged in the shell, and a luminous body. A drive circuit for driving the loudspeaker and the luminous body is arranged in the shell. The drive circuit is integrated on a circuit board which is assembled in the shell. The drive circuit comprises a PLC, a digital speech synthesis unit, a power amplifier unit and a digital isolator, wherein the PLC is connected with an intrinsic safety power supply, the digital speech synthesis unit is connected with an output end of the PLC, the power amplifier unit is connected with an output end of the digital speech synthesis unit, the digital isolator is connected with a signal input end of the PLC, the power amplifier unit is electrically connected with the loudspeaker, and the other output end of the PLC is electrically connected with the luminous body. The mining intrinsic safety type reversing alarm can give out warming light and simulate human voice in the reversing process of a vehicle, the simulated human voice can be set in the PLC as required so as to warn working staff behind the vehicle, security in the reversing process can be guaranteed and the production safety performance can be promoted.
Description
Technical field
The utility model relates to a kind of Mine-used I. S back-up buzzer that is assemblied in mine vehicle rear.
Background technology
Existing mine car back-up buzzer, only has simple buzzer, in use, can not give the warning of staff's actv., often cause the generation of some accidents, bring certain potential safety hazard to production, also reduced staff's working environment safety.
Utility model content
The utility model is for the deficiencies in the prior art, and the utility model provides a kind of Mine-used I. S back-up buzzer that light and simulation people sound can occur simultaneously, and it can give staff's actv. reminder alarm, avoids the generation of dangerous accident.
The utility model is achieved through the following technical solutions:
Mine-used I. S back-up buzzer, comprise housing, be arranged at the loud speaker in housing, luminary, in housing, be provided with and there is driving loud speaker, the driving circuit of luminary, this driving circuit is integrated on the circuit card being assemblied in housing, described driving circuit comprises the Programmable Logic Controller being connected with intrinsic safety electric source, the digital speech synthesis unit being connected with Programmable Logic Controller mouth, the power amplifier unit being connected with digital speech synthesis unit mouth, and the digital isolator being connected with Programmable Logic Controller signal input part, described power amplifier unit and above-mentioned loud speaker are electrically connected, another mouth of described control able to programme and luminary are electrically connected.
Adopt such scheme, the input end of digital isolator connects the reversing controller of vehicle, in the time of vehicle backing, reversing controller just sends astern signal to digital isolator, and trigger the astern signal to finish in Programmable Logic Controller by digital isolator, Programmable Logic Controller is controlled the luminous of luminary like this, and in Programmable Logic Controller, edit the simulation voice value that needs loud speaker to send, and by the phonetic synthesis of digital speech synthesis unit, final synthetic simulation voice, again by the amplification of power amplifier unit, is sounded from loud speaker.The utility model can be in vehicle backing process, send warning light and simulation voice simultaneously, and simulation voice can be according to different needs, in Programmable Logic Controller, set, staff with this to rear view of vehicle is warned, guarantee the safety in reversing process, promote the safety in producing.
Further, between described digital speech synthesis unit and power amplifier unit, be connected with filter unit.Filter unit can carry out filtering to the clutter carrying in digital speech synthesis element output signal, guarantees the purity of aud. snl..
Further, described luminary is emitting led, is connected with the driving flashing circuit that drives luminary flicker between luminary and Programmable Logic Controller.In reversing process, by driving flashing circuit to drive the flicker of luminary certain frequency, remind the staff of rear view of vehicle to note with this like this.
Further, in order to guarantee to input the voltage stabilization in Programmable Logic Controller, between described Programmable Logic Controller input end, intrinsic safety electric source is connected with reducing transformer.
Further, the model of described digital isolator is ADUM1201.
Accompanying drawing explanation
Fig. 1 is the block diagram of the utility model driving circuit;
The specific embodiment
Below by by reference to the accompanying drawings the utility model being further described:
Referring to Fig. 1, Mine-used I. S back-up buzzer, comprise housing, be arranged at the loud speaker in housing, luminary, in housing, be provided with and there is driving loud speaker, the driving circuit of luminary, this driving circuit is integrated on the circuit card being assemblied in housing, driving circuit comprises the Programmable Logic Controller 2 being connected with intrinsic safety electric source 1, the digital speech synthesis unit 3 being connected with Programmable Logic Controller mouth, the power amplifier unit 4 being connected with digital speech synthesis unit mouth, and the digital isolator 5 being connected with Programmable Logic Controller signal input part, power amplifier unit and loud speaker 6 are electrically connected, another mouth and the luminary 7 of control able to programme are electrically connected.
When concrete enforcement, for driving circuit is more optimized, between digital speech synthesis unit and power amplifier unit, be connected with filter unit 8.Luminary 7 is emitting led, is connected with the driving flashing circuit 9 that drives luminary flicker between luminary and Programmable Logic Controller.Between Programmable Logic Controller input end, intrinsic safety electric source 1 is connected with reducing transformer 10.The model of digital isolator is ADUM1201.The digital speech synthesis unit that relates in the utility model, drive flashing circuit, digital isolator, Programmable Logic Controller, power amplifier unit etc. to be prior art, thereby again seldom repeat.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
