Abstract
The utility model provides photograph between a kind of station to look into liaison circuit, comprises first station signal control room PLC and second station signal control room PLC, sets up optical cable and 4 optical fiber link module OLM, the photograph between first station with second station is looked into liaison circuit and is connected by optical cable; The two ends of optical cable are respectively parallel with 2 OLM, wherein 2 OLM of one end parallel connection are connected on 2 redundancy communication module ET sockets of first station signal control room PLC by PROFIBUS netting twine, and 2 OLM of other end parallel connection are then connected on 2 redundancy communication module ET sockets of second station signal control room PLC by PROFIBUS netting twine.Realize shining between station owing to replacing signal cable with optical cable looking into liaison circuit, signal cable investment can be saved, simplify circuit, facilitate fault handling, improve hauling operation efficiency, ensure traffic safety.
Description
Technical field
The utility model belongs to railway signal system field, particularly relates to a kind ofly to look into liaison circuit for the photograph between two websites.
Background technology
At present, all adopt large core number signal cable to connect according to looking into liaison circuit between the station of smelter, due to distant between two stations, therefore signal cable lays the higher investment cost of needs; In addition Along Railway bad environments, thus bring many unfavorable factors to the handling labor of circuit.
Along with the development of microcomputer interlocking and PLC technology, connect transmission of electric signals by signal cable by between conventional stations and change optical signal according to looking into liaison circuit into and to transmit in computer communication mode and become possibility according to looking into information.
Summary of the invention
The utility model aims to provide one can simplify circuit, saves signal cable investment, facilitates between the station of fault handling according to looking into liaison circuit.
For this reason, the solution that the utility model is taked is:
According to looking into liaison circuit between a kind of station, comprising first station signal control room PLC and second station signal control room PLC, it is characterized in that, setting up optical cable and optical fiber link module OLM, the photograph between first station with second station is looked into liaison circuit and is connected by optical cable; The two ends of optical cable are respectively parallel with 2 OLM, wherein 2 OLM of one end parallel connection are connected on 2 redundancy communication module ET sockets of first station signal control room PLC by PROFIBUS netting twine, and 2 OLM of other end parallel connection are then connected on 2 redundancy communication module ET sockets of second station signal control room PLC by PROFIBUS netting twine.
Described optical cable is 4 cores.
The beneficial effects of the utility model are:
Realize shining between station owing to replacing signal cable with optical cable looking into liaison circuit, signal cable investment can be saved, simplify circuit, facilitate fault handling, improve hauling operation efficiency, ensure traffic safety.
Accompanying drawing explanation
Fig. 1 is according to looking into liaison circuit sketch between station.
In figure: 1 is first station signal control room PLC, 2 is second station signal control room PLC, and 3 is PROFIBUS netting twine, and 4 is 4 core optical cables, and OLM is optical fiber link module, and ET is PLC redundancy communication module.
Detailed description of the invention
As seen from Figure 1, according to looking into liaison circuit between the utility model station, be on the basis of original first station signal control room PLC1 and second station signal control room PLC 2, set up 4 core optical cables 4 and 4 OLM, the photograph between first station with second station is looked into liaison circuit and be connected by 4 core optical cables 4.
The two ends of 4 core optical cables 4 are respectively parallel with 2 OLM, wherein 2 OLM of 4 core optical cable 4 left end parallel connections are connected on 2 ET sockets of first station signal control room PLC 1 by PROFIBUS netting twine 3, and 2 OLM of 4 core optical cable 4 right-hand member parallel connections are then connected on 2 ET sockets of second station signal control room PLC 2 by PROFIBUS netting twine 3.
