Description
Technical field
The utility model is related to data acquisition voice-transmission system, and specifically a kind of data based on CAN communication are adopted
Collection voice-transmission system.
Background technology
Underground coal mine environment is complicated, and field condition is severe, and interference is big.Limited by geographical, space simultaneously, many equipment peaces
Mounted in different location, along the line distance.Such as Belt transport line, built on stilts pedestrian's cableway, coal-face etc., it is desirable to need real-time
The ruuning situation of these equipment is monitored, running into emergency must at once alarm and send stop sign, to real-time, reliability
It is required that very high.Because the more dispersed distance in working site is remote, contact when staff repairs each other is inconvenient.At present also
There is no a kind of good method to solve this problem, therefore how quickly and accurately to detect failure and send alarm to upper level
Connecting each other between information and staff just seem very crucial, is also this area technical problem urgently to be resolved hurrily.
Utility model content
The utility model aims to solve the problem that the data acquisition of underground coal mine different location, between Address Recognition, operating personnel
Connect problem each other, and a kind of data acquisition voice-transmission system based on CAN communication is provided.
The utility model solve its technical problem use technical scheme be：
A kind of data acquisition voice-transmission system based on CAN communication, including data acquisition voice transfer circuit list
Unit, host computer system, data acquisition voice transfer circuit unit include single-chip microcomputer, voice module, current source, sensor,
Transmitter, sensor one end connection current source, other end connection single-chip microcomputer, transmitter is directly connected with voice module；Multiple institutes
The data acquisition voice transfer circuit unit stated is distributed in diverse location, leads to each other and between host computer system
Respective single-chip microcomputer is crossed to be connected with CAN.
When outside sensor actuation, circuit turn-on produces potential difference, applies voltages on the AD passages of single-chip microcomputer；It is logical
Cross Real-time Collection to voltage change signal carry out the generation of failure judgement, the address information that is pre-set by single-chip microcomputer is judged
The position that failure occurs, and address information uploaded into upper level system.
Meanwhile, the personnel in different work place can be connected each other by transmitter, mutual transmission information.Operating personnel couple
Quasi- transmitter is spoken, and acoustic information is modulated into carrier frequency signaling by voice module, is transferred to the voice mould of another circuit unit
On block, audio-frequency information broadcasting is then reduced into.
Using the utility model of upper technical scheme, compared with prior art, its advantage is：
The method of voltage change is produced come in solving the problems, such as practical application by sensor actuation using current source, can
Accurately, reliable, quick detection failure carries out emergency alarm, and abort situation can be recognized accurately.While Field Force
Voice call contact can also be carried out.
Further, the utility model preferred scheme is：
Described single-chip microcomputer model is PIC18F4580, voice module model TA2024BJK0538.
Brief description of the drawings
Fig. 1 is the structured flowchart of the utility model example；
Sequence number in figure：1- current sources；2- single-chip microcomputers；3- voice modules；4- sensors；5- transmitters；6- host computers
System.
Specific embodiment
The utility model is further described below in conjunction with accompanying drawing and example.
Referring to Fig. 1, a kind of data acquisition voice-transmission system based on CAN communication, by multiple data acquisition voices
Transmission circuit unit and host computer system 6 are constituted, and each data acquisition voice transfer circuit unit is by current source 1, list
Piece machine 2, voice module 3, sensor 4, transmitter 5 are constituted, the one end of sensor 4 connection current source 1, other end connection single-chip microcomputer 2,
Transmitter 5 is directly connected with voice module 3；Multiple data acquisition voice transfer circuit units are distributed in diverse location, lead to respectively
CAN is crossed to be connected with host computer system；Multiple data acquisition voice transfer circuit units are each other by respective
Single-chip microcomputer is connected with CAN.
The type of single-chip microcomputer 2 in the present embodiment uses PIC18F4580, voice module 3 to use TA2024BJK0538.
The system course of work is summarized as follows：
When sensor 4 is acted, circuit turn-on.Signal is added on the acquisition channel of single-chip microcomputer 2, the electricity arrived by Real-time Collection
Pressure signal writes the internal program address of single-chip microcomputer 2 to differentiate the position of failure generation with regard to energy failure judgement according to prior, together
These defect contents and address information can be uploaded to host computer system 6 by the communication of Shi Liyong CANs.
Operating worker can carry out sending words by transmitter 5, voice signal is changed into data signal, and modulated
It is transmitted in connection cable.After the circuit of connection receives the signal of modulation treatment, sound is reduced into and by raising one's voice
Device is played back.So the personnel in different work place can just connect each other, mutual transmission information.
Above-described embodiment is only to the utility model explanation for example.The utility model those of skill in the art
Member can be made various modifications or supplement to described instantiation or be substituted using similar mode, but can't be inclined
From spirit of the present utility model or surmount scope defined in appended claims.
