Abstract
The present utility model discloses a DCS terminal module on-line overhaul device. The device comprises four conducting wires which are arranged side by side, two ends of the four conducting wires are respectively and correspondingly connected with each terminal of two DCS terminal modules, a first conducting wire and a second conducting wire are electrical wires, and a third conducting wire and a fourth conducting wire are DP buses. In the device, the electrical wires and the DP buses are respectively connected with each terminal of adjacent two DCS terminals of an abnormal DCS terminal module, normal communication and power supply of the adjacent two DCS terminal modules can be guaranteed, the DCS terminal module which is in failure in the situation that the whole production device is continued to work can be processed, production efficiency of enterprises can be enhanced, and production losses of enterprises can be reduced.
Description
Technical field
The utility model relates to a kind of line apparatus for examination and repair, relates in particular to a kind of DCS of being used for terminal module on-bne repair device.
Background technology
DCS is the english abbreviation (Distributed Control System) of dcs, and automatic control industry at home is referred to as Distributed Control System (DCS) again.DCS adopts several controllers (control station) that the numerous reference mark in the production run are controlled usually, also can carry out exchanges data through the network connection between each controller.Computer operator station is adopted in operation, is connected with controller through network, collects production data, passes on operational order.High reliability is first requirement of Process Control System.Two kinds of DCS systems of SMART PRO of Hollysys and MACSV; Control station I/O architecture all adopts grafting I/O modular design on the DCS terminal module; The DCS terminal module is provided with connecting terminal block, is respectively arranged with DP communication anode 1, DP communication negative terminal 2, power input 3 and earth terminal 4 interfaces on the connecting terminal block.The DCS terminal module adopts series system link from the beginning to the end in the same station; As shown in Figure 1; The DP communication anode 1 of DCS terminal module N-1 and DP communication negative terminal 2 are connected the DP communication anode 1 and DP communication negative terminal 2 of DCS terminal module N respectively; The power input 3 of DCS terminal module N-1 and earth terminal 4 are connected the power input 3 and earth terminal 4 of DCS terminal module N respectively; The DP communication anode 1 of DCS terminal module N and DP communication negative terminal 2 are connected the DP communication anode 1 and DP communication negative terminal 2 of DCS terminal module N+1 respectively; The power input 3 of DCS terminal module N and earth terminal 4 are connected the power input 3 and earth terminal 4 of DCS terminal module N+1 respectively, and communication is not redundant with power supply.I/O module tenaculum hot-line insertion and extraction wherein.In case when a certain DCS terminal module breaks down, will influence follow-up series connection I/O module cisco unity malfunction.Because the DCS terminal module adopts series system link from the beginning to the end in the same station, communication is not redundant with power supply, can't carry out online treatment, can only behind system blackout, could handle the DCS terminal module that breaks down through stopping the whole production device.
The utility model content
The purpose of the utility model provides a kind of DCS terminal module on-bne repair device, can under the situation that the whole production device works on, handle the DCS terminal module that breaks down, and improves enterprises production efficiency, reduces the enterprise production loss.
The utility model adopts following technical proposals:
A kind of DCS terminal module on-bne repair device comprises four leads that are arranged side by side, two each terminals of DCS terminal module of the corresponding respectively connection in the two ends of four leads, and first and second leads are electric wire, third and fourth lead is the DP bus.
Also comprise housing, be provided with fixing four leads of stationary installation in the housing.
Described DCS terminal module is FM131A, FM131-C-A, FM131-E-A, FM132, FM133 or FM134 terminal base.
Described four lead two ends are provided with the electric wire folder.
The utility model utilizes electric wire and DP bus to be connected adjacent two each terminals of DCS terminal module that unusual DCS terminal module takes place respectively; Guarantee that communication of adjacent two DCS terminal modules and power supply are normal; Can under the situation that the whole production device works on, handle the DCS terminal module that breaks down; Improve enterprises production efficiency, reduce the enterprise production loss.

Fig. 2 is the structural representation of the utility model;
Fig. 3 is the user mode synoptic diagram of the utility model.
Embodiment
As shown in Figure 2; The utility model comprises housing 5; Housing 5 inside are fixed with first lead 6, second lead 7, privates 8 and privates 9 through stationary installation 10; Housing 5, the first leads 6 are all extended at the two ends of four leads and second lead 7 adopts electric wire, and privates 8 adopts the DP bus with privates 9.Be connected with terminals for the ease of lead, four lead two ends are provided with the electric wire folder.
When a certain DCS terminal module occurs when unusual; As shown in Figure 3; When the N terminal module occurs unusual; Can the two ends of first lead 6 in the utility model be connected the power input 3 of DCS terminal module N-1 and the power input 3 of DCS terminal module N+1 respectively; The two ends of second lead 7 are connected the earth terminal 4 of DCS terminal module N-1 and the earth terminal 4 of DCS terminal module N+1 respectively, the two ends of privates 8 are connected the DP communication anode 1 of DCS terminal module N-1 and the DP communication anode 1 of DCS terminal module N+1 respectively, the two ends of privates 9 are connected the DP communication negative terminal 2 of DCS terminal module N-1 and the DP communication negative terminal 2 of DCS terminal module N+1 respectively.First lead 6 and second lead 7 can guarantee that the power supply of DCS terminal module N-1 and DCS terminal module N+1 is normal, and privates 8 can guarantee that with privates 9 communication of DCS terminal module N-1 and DCS terminal module N+1 is normal.After each lead connects on request in the utility model, can pull down the unusual terminal module N of appearance and keep in repair.Can overhaul the FM131A of Hollysys, FM131-C-A, FM131-E-A, FM132, FM133 or FM134 terminal base with the utility model.
The utility model not only is confined to the foregoing description, also can be with the use that is bonded as one side by side of four leads.
