Embodiment
Compressed air gas source system is a kind of system for producing compressed air, and the air supply system includes helical-lobe compressor, pressure
Contracting machine distribution system, refrigerant type dryer, filter, air accumulator, pipe-line system, cooling circulating water pump, blower fan system, valve system
The part such as system, temperature and pressure transmitter is constituted.
Centralized control system, including data acquisition module, signal transmission module, programming module, human-computer interaction interface module.
Data acquisition module is mainly responsible for believing the compressor (totally 17) at scene, cooling driers (7), valve, sensor
Number (including control signal and state quantity signal) collection is used for subsequent treatment.Data acquisition module mainly includes S7-200PLC
I/O module, Gateway modules, local IO, remote I/O.
The state quantity signal of compressor is unified to be gathered using Gateway modules using CAN mode, the control of compressor
Signal is acquired using two ways：The compressor nearer apart from main control cabinet is gathered by local IO；Apart from main control cabinet
Compressor farther out is gathered using remote I/O.
Cooling driers are divided into 3 kinds of models：Wherein the big cooling driers equipment of flow (totally 4) uses S7-200PLC IO moulds
Block gathers its state quantity signal, its control signal according to its apart from main control cabinet distance, apart from nearer cold dry of main control cabinet
Machine is gathered by local IO, is gathered apart from the cooling driers of main control cabinet farther out using remote I/O；The cooling driers of remaining 2 kinds of model are set
It is standby according to it apart from the distance of main control cabinet, the cooling driers nearer apart from main control cabinet gather its state quantity signal by local IO
And control signal, its state quantity signal and control signal are gathered using remote I/O apart from the cooling driers of main control cabinet farther out.
Valve arrangement and sensor device are according to it apart from the distance of main control cabinet, and the valve nearer apart from main control cabinet lead to
Cross local IO and gather its state quantity signal and control signal, its state is gathered using remote I/O apart from the valve of main control cabinet farther out
Measure signal and control signal.
Signal transmission module be responsible for by data acquisition to signal be transferred to after signal transacting and protocol conversion it is upper
Machine LabVIEW is used.Signal transmission module mainly include S7-200 PLC, S7-300PLC, STEP7 network configuration,
Simatic.Net is uploaded, NI OPC Server conversion portions.
Due to the variation of acquisition module, multiple module gathers and transmitted letter using different agreement and transmission mode
Number, so centralized control system will carry out signal transmission using a variety of bus modes, most signal integration turns into host computer at last
The state that LabVIEW can be recognized.
Compressor quantity of state is pressed address by Modbus bus transfers to S7-300PLC by Gateway modules；Remote I/O
Pass through Profibus-DP bus transfers to S7-300PLC；Data are passed through EPA by S7-200PLC and S7-300PLC
Transmitted according to address；S7-200PLC and S7-300PLC just constitutes a local according to address after STEP7 network configurations
Net.Configured and uploaded by Simatic.Net, the data of upload support OPC agreements, and LabVIEW softwares pass through NI OPC Server
Required data are taken out in the form of shared variable.
CAN is controller LAN (controller area network) abbreviation, with following features：1.
Real-time, long transmission distance, anti-electromagnetic interference capability are strong, cost is low；2. use two wire serial communication mode, error detecing capability
By force, it can be worked in strong noise interference environment；CAN no matter principal and subordinate, communication mode flexibly, with high implementation, highly reliable
Property.
Modbus buses are a kind of current industry standard agreements, and it, which defines a controller, can recognize the message knot used
Structure, is communicated but regardless of them by which kind of network.Only one of which main website in Modbus universal serial bus, at most can be with
There are 256 substations.
PROFIBUS-DP buses are a kind of many main station systems, it is possible to achieve multiple controls, configuration or visualization system are one
Mutual operation in bar bus.Data can just be sent without external request by possessing the main website of access right (token), and slave station is one
Passive equipment is planted, bus access power is not enjoyed.PROFIBUS-DP can have multiple main websites simultaneously, can at most connect 127 from
Stand.
EPA is the extension of traditional ethernet, is the combination of standard ethernet and universal industrial protocol.Industry with
Too net has following feature：1. the certainty and real-time of communication, the traffic rate of EPA can reach 10G/s, this
It is EPA biggest advantage.2. Stability and dependability is high.3. it is safe.
OPC agreements are an industrial standards, and it includes the regular set of a whole set of interface, attribute and method, for excessively program control
System and automated manufacturing.At present, OPC has turned into the default scheme that industrial quarters system is interconnected, is that industrial monitoring programming is brought
Convenient, user is worried without being the problem of communications protocol again.
Using LabVIEW softwares as the virtual instrument of representative, generally using computer platform, the special function of traditional instrument
With hardware capability software implementation, make sensor and computer structure altogether.What user can define and design an apparatus as needed
Test function.LabVIEW uses the graphic programming mode based on flow chart, and programming is simple, but in functional completeness and application
It is not a halfpenny the worse old in flexibility.At present, to have been widely used for T ＆ M, process control and industry automatic by LabVIEW
Change and laboratory research.
Programming module includes PLC program design and LabVIEW programming two parts.
It is main to consider following at 2 points in described PLC program design：1.S7-300PLC in timing acquiring Modbus communications
The compressor quantity of state of biography, CP341-1 modules, which are installed, sets PLC to be Modbus main websites after driving and Dongle, set every 250 milli
Second once, will be delivered to according to Modbus collection subprograms collection of call by location after the completion of collection after data progress Conversion of measurement unit
Corresponding data background block is uploaded；2.S7-200PLC is by ethernet module CP243-1, configuration ethernet transmission journey in program
Sequence simultaneously sets IP address, and the data that changing needs upload into corresponding VB data types.
LabVIEW programmings handle corresponding shared variable, and PLC reality is operated and read according to mailing address addressing
When state value, operated, controlled, recorded, stored by programming realization.
In described LabVIEW programmings, shared variable is added in engineering, LabVIEW program designs first
Hold and flow：1. initialization；2. equipment is selected；3. equipment operation warning light, sensor reading；4. compressor, cooling driers
Status display；5. compressor, cooling driers, valve start-up and shut-down control；6. alarm logging；7. log；8. operation alarm logging is looked into
Ask；9. exit monitoring.Compressor, cooling driers, compressor in LabVIEW programmings can be started after valve and cooling driers start
The logical order of equipment interlocking is as shown in Figure 2.
Human-computer interaction interface is the performance that centralized control system is presented in the external world, is the major embodiment form of centralized control system, is also
The platform of operating personnel's operation, is the core of centralized control system.
