Description
Technical field
The present invention relates to pipe-line system technical fields, control and fill in particular to a kind of pipeline yard scene remote I/O
It sets.
Background technique
For detecting and controlling for pipeline yard field device, previous engineering is all made of detecting and controlling field device
On direct laying to the control system PLC cabinet of station control room, or field device detected and controlled into cable laying
On tele-control system PLC machine cabinet in remote cabinet near to field device, then will remotely it be controlled by network communication
The method that information on system PLC transmits the control room control system PLC that arrives at a station.
If using detecting and controlling field device on direct laying to station control room control system PLC cabinet
Method, the cable that live all devices detect and control all need laying to station control room, the cable count not only laid in this way
Amount is big, and investment is high, and the PLC machine cabinet quantity for being bound to cause control room is also very much, and the area of control room is also very big, corresponding to levy
Ground area also increases；Meanwhile the cable of detection, the control of control room breaks down once field device arrives at a station, due to scene
Number of cables is big, type is more, then is difficult to confirm specific Method of Cable Trouble Point at the scene, brings difficulty to Maintenance and Repair；And such as
There is operation troubles in fruit station control system PLC primary processor, just influences whether the monitoring and control of all field devices, reduces
Reliability, stability and the safety of control system；In addition, increase detects and controls equipment if field device dilatation from now on
Parameter, the cable to arrive at a station between control room control system PLC from on-site test, control equipment need to be just laid again, due to pipe
Road yard is explosion-proof area, and transformation can make troubles to production run, also increases improvement expenses.
If using will be in the remote cabinet of field device detected and controlled near cable laying to field device
Tele-control system PLC, then information on tele-control system PLC is transmitted by control room control system of arriving at a station by network communication
Method on PLC, although reducing a large amount of cables between station control system PLC and tele-control system PLC in this way (by more
Rigid line connecting cable becomes single or double joint network communication cable), control room cabinet quantity is decreased, control room is reduced
Area, but equipment tele-control system rack room, the cabinet quantity in live rack room nearby must be arranged at the scene in this kind of method
Equally also very much, area is also very big, and corresponding land area will not be reduced, and there is still a need for lay extremely for the cable of on-site test and control
On tele-control system PLC between remote cabinet；While the normal work in order to guarantee tele-control system PLC, it will also be to remote
Taken between process control system cabinet necessary heating, power supply, fire alarm detection etc. measures, certainly will increase in this way investment at
This.If field device breaks down to the detection of tele-control system between remote cabinet, control cable, due to largely existing
Field cable exists, then is difficult to confirm specific Method of Cable Trouble Point at the scene, brings difficulty to Maintenance and Repair；If remote machine
There is operation troubles in tele-control system between cabinet, just influences whether detecting and controlling for all field devices, reduces control
The reliability of system, stability, safety；Meanwhile if scene increases detection control equipment from now on or increase detects and controls
Parameter then needs to lay again from on-site test, control equipment to the cable the tele-control system PLC between remote cabinet,
Since pipeline yard is explosion-proof area, it can make troubles to production run, also increase improvement expenses.
Therefore, no matter which kind of above-mentioned method is used, can all influences safety, the reliability, stabilization of detecting and controlling system
Property, the investment of control system is also increased, the dilatation of field device from now on is unfavorable for, is brought to production run and Maintenance and Repair tired
It is difficult.
