The application TS-3000 unit integrates the integrated control system in the energy recycling unit, to it is in sole possession of the characteristic, unit's start procedure, the oil pulls down the oil pump self-starting procedure, the jigger procedure, the electricity generation flings the load procedure, the unit interconnection procedure and guards against the buzz control, the velocity modulation control, the event order record and the hardware breakdown diagnosis and so on perfectly unifies in together. TS-3000 because used the tertiary redundancy fault-tolerant hardware disposition safely to cause the system to be reliable. And application which achieves success in the domestic multi- wraps energy recycling unit, has obtained the remarkable economic efficiency.

Key word:

The unit integrates the integrated control system; Tertiary redundancy fault-tolerant; Safe is reliable

1st, foreword

Now the domestic majority of compressors control system uses disperser -like PLC or DCS and so on the combination carries on the control, if unit's velocity modulation uses TRICONEX Corporation the TS310 velometer or the WOODWARD 505 velometers, the unit use CCC Corporation which guards against the buzz system to have guards against the buzz controller, some voluntarily establishments guard against buzz control software, the compression unit stop the interconnection to use the non- redundancy PLC or DCS realize. The disperser -like system each part of between signal joint selects the communication method (RS-232 or RS-485) carries on, communication speed slower, wiring intriguing, the non- redundancy or the double redundancy PLC usability low, the reliability is bad. Such system for the energy recycling unit's security, is stable, the long period movement brings the very big threat. In order to guarantee the unit long period stable movement, most refines oil, the chemical enterprise, already started to use the tertiary redundancy fault-tolerant control system. At present in the petroleum, the chemical industry, the metallurgy, the railroad and so on the widespread application tertiary redundancy fault-tolerant control system is the TRICON control system which American TRICONEX Corporation produces. It integrates by the Beijing 康吉 woods automatic equipment limited liability company. At present applies on the energy recycling unit the model is TS-3000.

2nd, tertiary redundancy fault-tolerant control system concept and TRICON tertiary redundancy fault-tolerant control system

The tertiary redundancy control system is composed by three quite same not less than systems legs (besides power source module is dual redundancy), each system leg independently executive control program and with other two legs multi-tasking. The TRICON control system shows through the tertiary redundant structure TMR like chart 1, (TMR is tertiary module redundant structure abbreviation), but produces its fault-tolerant ability. Namely has to the transient state and the stable state makes a mistake the situation investigation discovery ability as well as adopts the hardware vote mechanism to all to come from the region field digital input and the output carries on the inspection and examines decides. The analog input on-line measure ability adopts the value selective treatment process.

TRICON system (TMR) each digital input/output module all contains three quite same not less than mutual isolation the legs. Each leg includes a I/O microprocessor, and receives its output meter from on its corresponding main processor I/O communication processor. Three main processors the high speed main line system which suitably match through, is called as is the TRIBUS system intercommunication. All digital output module, besides the dual DC module, all uses four heavy output circuits, this electric circuit just about to exerts in the load is carried on to each single output signal when them the vote. This votes the electric circuit the foundation is parallel or the serial way, in three drivers two may vote takes ON. The dual digital output module has single parallel or the serial way, but in three takes two votes processes alone to affect to each switch.

The TRICON system every time scans time, the host processor all if the neighbor carries on the communication through TRIBUS and 同步�? TRIBUS will vote the digital data-in, the comparison output data, and the analog input data transcription delivers each main processor. The main processor executive control program and the output which produces by the control procedure gives the output module. Except that makes beside the vote to the data-in, TRICON also votes the output data. This is in leaves on the scene recent output module to complete, in order to investigates any is wrong and compensates, investigates any possibly appears in the TRIBUS vote with gives between the finally output mistake which the scene goes.

3rd, the TS-3000 unit integrates the integrated control system in energy recycling unit application

The energy recycling unit is causes the haze energy reclaimer using the high temperature haze heat expansion acting principle the smoke machine acting. The energy recycling unit generally divides into two units, three units and four units several kinds, three units and four units in refine oil in the enterprise to apply broadly. TRICONEX Corporation according to the TS-3000 unit which the unit characteristic develops to integrate the integrated control system, it in the energy recycling unit, the unit interconnection, the unit controls, the instruction and SOE (event order recording) the function, the hardware breakdown diagnosis integration realizes in a system. And omni-directional controls to the unit carries on the management. Concrete application as follows:

3.1st, energy recycling unit's interconnection protection control function realization

The energy recycling unit's unit's start procedure, the oil pull down the oil pump self-starting procedure, the jigger procedure, the electricity generation flings the load procedure, the interconnection procedure and guards against the buzz control, the velocity modulation control and so on. Specially 主风 machine guards against the buzz control function and the unit velocity modulation control function, all may completes through the TriStation 1,131 software programming and the configuration.

With TriStation 1,131 programming and configuration software which nimbly facilitates, realization energy recycling unit's logic and control function programming and configuration. It supports the IEC language, specifically has following three languages.

Function block graph (FBD) language. The graphical language, by the function block unit which interlocks the proceed signal streamline is composed the network constitution, may transmit the logical number in the FBD unit between, entire 型数, real number and other type data.

Trapezoidal chart (LD) language. The graphical language, all is composed the network constitution by the beginnings and ends with the power line connected segment. The link gets up from the power line to the LD mark transmission binary system data which interlocks. Is same with the function block, LD uses a set to represent the relay electronic contact and the coil standard mark takes the instruction.

Structure text (ST) language. Is similar to the PASCAL high-quality text language, uses in to connect the programming. The ST language has provided some kind of production logic and the arithmetic expression method; As well as structure procedure production, like statement (IF... THEN... ELSE). The ST language may quote the function block.

Usually uses the ST language compilation procedure, the production user function block. For instance guards against the user function block which the buzz function block, the velocity modulation function block as well as the user needs to realize and so on.

And so on carries on the programming and the configuration using the FBD language to the energy recycling unit's logic and the control function, the realization unit starts, the interconnection and the control logical function.

TriStation 1,131 software supports all examples procedure simulation simulation, therefore the user may off-line debug the procedure.

TriStation 1,131 also must carry on the programming and the configuration establishment to the SOE function, after the procedure which the configuration completes completely takes off costume the TS-3000 unit integrated control system, automatically produces including to take off costume the edition number SOE disposition document * soe, this disposition document copy to Triconex/Tr1soe/soeconfig table of contents under. Must want to see the energy recycling unit the SOE recording event, must use the network communication connection. Moves the SOE procedure and founds a filename, this time can appear the disposition document option, chooses the good disposition document, then moves SOE then to demonstrate the event order record.

3.2nd, TS-3000 control failure diagnosis function

The CPU breakdown diagnosis may use along with equipment belt special-purpose CPU diagnosis software and the electric cable, carries on the breakdown diagnosis to CPU. Also may use the TriStation 1,131 modules diagnoses function to carry on the diagnosis, when TriStation 1,131 has been normal with the system communication, chooses under TRICON menu TRICON Diagnostic Panel then according to the connection (Connect) the button, this time appears the dialog box option, if uses the MODBUS communication, chooses TRICON Serial Por, if the NCM network communication, chooses TRICON Network, after chooses the normal communication way, can demonstrate the edition number, the memory size and uses for in TRICON the control procedure execution scanning time information, as well as system failure condition. If is the transient state breakdown spot, but also may eliminate the breakdown spot through software. Moreover also may various modules condition address Alias which provides through the TS-3000 control system in carry on the communication with on position machine picture MMI, demonstrates various modules from the MMI picture the active status.

Each kind of model module digital output, carries out one kind of special pattern output voting machine diagnosis (OVD) to each. Generally speaking, each spot order condition exists in the OVD implementation by the temporary local constable above the output driver, one each one stores one by one. Returns on the module link permits to enter the stadium each microprocessor for this read-out output value, decided in output electric circuit whether exists has potential failure. (Cannot tolerate free length regarding these signal transmission installment, all may endure in AC and on DC voltage digital output module OVD moves.)

After the TRICON system can support the partial modules to have the breakdown long-term normal operation. If spare lacks the goods or the system for a while is installed in the remote districts, the service is possibly postponed. Because its TMR structure and hot reserve capacity, if moves when the I/O module appears the breakdown, the system automatically carries on the hot transformation, has the breakdown I/O module from the use to change the use spare module. Namely the system on automatically uses the movement the I/O module to be close to in the mortise the backup I/O module. This time has the breakdown module no longer to move and to report to the police.

3.3rd, TS-3000 synthesis safety system

TriStation 1,131 provides each kind of security rank the password protection. In inlays the safety system through the establishment user name and the password, the control enters the project and the procedure each kind of merit energy level. Through the TriStation 1,131 safety systems dialog box, may change the jurisdiction which, the increase and the cancellation user enters. Any is recorded to the safety system revision in the project historic record.

The system passed the TUV authentication, confirmed the system function satisfies the biggest security which the essential process application requests and the not interrupted operation request. TriStation 1,131 acts according to the TUV authentication use advancement the request, achieved Germany safely requests fifth level of and the sixth level of request.

In the MMI operation picture, differently operates the rank according to the user, set up entered the system the security jurisdiction. For example: Operator level, workshop section chief level and programmer level and so on. And all records to all operations in the historic record.
