Abstract
The invention discloses a combination line multiplexing device of an underground coal mine winch. The combination line multiplexing device comprises a relay, a communication bus, a data communication line, a voice communication line and a call button, wherein the communication bus is communicated with the relay; the data communication line is connected with a normally closed contact of the relay; the voice communication line is connected with a normally open contact of the relay; the call button is communicated with the relay. The combination line multiplexing device is simple in structure, a time division multiplexing technology is adopted for voice communication and data communication, the same line is used, and different pieces of information are transmitted under different states. The data communication is carried out in the running process of the winch under normal conditions, and the voice communication is not carried out in the process; during the voice communication, the winch does not run, and the data transmission is not carried out. Therefore, a time division communication mode can be adopted, namely the voice communication can be carried out by pressing down a voice communication button, the line is occupied, and the data communication is not carried out. After the button is loosened, the normal data communication is carried out, and the voice communication is not carried out.
Description
Technical field
The present invention relates to a kind of signal control device of underground coal mine winch, in particular a kind of communication line multiplexer of underground coal mine winch.
Background technology
In current underground coal mine winch transport systems, all need voice analog signal communication and data communication two communication lines.If connect such outside line separately, link cost is high, and wiring complexity increases the difficulty of field wiring.And once et out of order, overhaul also more complicated, add the construction complexity of whole system undoubtedly.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of communication line multiplexer of underground coal mine winch, realize the time-sharing multiplex of data communication and speech communication.
The present invention is achieved by the following technical solutions, the present invention includes relay, the communication bus be communicated with relay, the data communication circuit be connected with relay normally closed contact, the voice communication circuit be connected with relay normally open contact, the push-to-talk button be communicated with relay.
Described push-to-talk button is pressed, and relay adhesive, voice communication circuit is connected on communication bus.
The present invention has the following advantages compared to existing technology: structure of the present invention is simple, and speech communication and data communication adopt time-sharing multiplexing technology, uses same circuit, transmits different information under different conditions.Just carry out data communication in winch operational process under normal circumstances, this process does not carry out speech communication, and during speech communication, winch does not run, and does not carry out data transmission.Therefore can adopt the pattern of time-sharing communication, namely pressing speech communication button can speech communication, and circuit is occupied, does not carry out data communication.Carry out normal data communication after release button, do not carry out speech communication.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises relay 1, the communication bus 2 be communicated with relay 1, the data communication circuit 3 be connected with relay 1 normally closed contact, the voice communication circuit 4 be connected with relay 1 open contact, the push-to-talk button 5 be communicated with relay 1.Push-to-talk button 5 is pressed, and relay 1 adhesive, voice communication circuit 4 is connected on communication bus 2.
Time normal, data communication circuit 3 is connected on communication bus 2 through relay 1 normally closed contact, can data communication normally.When needs carry out speech communication, the adhesive of press-to-talk button 5 relay 1, voice communication circuit 4 is connected on communication bus 2, can carry out speech communication.Data communication circuit 3 is cut off automatically, completes time-sharing multiplex communication bus 2 function.
Claims (2)
