Accompanying drawing explanation
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the schematic flow sheet of the inventive method；
Fig. 2 is the schematic diagram of tank field production data acquisition in the present invention.
Detailed description of the invention
The present invention is quickly generated by the patterned dispatch command of research, is audited and assign technology online, proposes a kind of tank
District's oil transportation job scheduling optimization method, can instruct and reduce scheduling error by Optimized Operation by the method, improve work efficiency.
A kind of tank field oil transportation job scheduling optimization method, comprises the following steps:
A uses C# language, and Visio carries out secondary development, carries out crude oil tank farm and product oil tank field work on this basis
The graphical configuration of skill: carry out the drafting of process chart；Collect instrument, the information of equipment, carry out the base of tank, valve, pump, pipeline
This attribute configuration.According to source difference, attribute is divided into static state and dynamic attribute.
B by the creation data of production scene host computer, by Ethernet write RTU (Remote Terminal Unit, far
Journey terminal unit, can be responsible for on-site signal, the monitoring and control of industrial equipment.RTU is to constitute CIMS in Enterprise
Core apparatus, generally inputted/go out module, microprocessor, wire/wireless communication apparatus, power supply and shell etc. by signal and form,
By microprocessor control, and support network system).The data acquisition server newly increased in the present invention passes through RS-232 or RS-
485 serial port communicating protocols read data from RTU, and write in SQL Server data base, thus are that tank field oil transportation operation is adjusted
Degree optimization system provides corresponding data.Between RTU to server of the present invention data transmission be unidirectional, it is achieved that system with
Produce the physical isolation of net.
C reads real-time production data, in conjunction with manually arranging condition, specialist system judges each tank, pump, valve, pipeline
Use state (is included in state, malfunction, upstate), and writes in SQL Server data base.Each equipment state
Upstate judgment rule is as follows:
Tank: before tank, valve cuts out, tank liquid level<height reports and tank liquid level>low report, and fault-free instruction, then tank can be used.
Pump: monitoring current is more than 0, pump intake, outlet pressure are respectively greater than restriction, then pump leaves, unavailable；Otherwise, exist
Under fault-free instruction, available.
Valve: switch valve reach a state when being 1, valve is opened, unavailable；The pass of switch valve puts in place when being 1, and valve cuts out, can
With；A state that reaches of regulation valve is 1, and valve is opened, unavailable；The pass of regulation valve valve when being 1 that puts in place cuts out, available；Regulation valve
Reach a state be 0, close put in place be 0 and feedback aperture more than 0 time, valve is opened, unavailable.
Pipeline and other: according to state and the annexation of valve, by breadth first search's method, labelling pipeline and other make
Use state.
D be manually specified operation start-stop apparatus, must through equipment, avoid equipment, based on the annexation of tank field equipment,
In conjunction with upstate and the constraints of each equipment, obtain some of the work route optimized with inference engine.
The exploitation of described inference engine approximately as: in order to improve computational efficiency, carried out based on BSTN in MATLAB
The exploitation of the algorithm bag of net.For the ease of application, algorithm bag is packaged into DLL form.In Visual Studio development kit
Interpolation is quoted, and appoints the interface of both sides.Interface shape such as table 1 below:
Table 1
Above-mentioned constraints is divided into the most several:
1) minimum through node
So-called " node ", including: valve, pipeline junction point.This kind of mode, makes the operational motion of operative employee minimum.
2) length is the shortest
The shortest as constrained objective with length of pipeline, this kind of mode, can reduce the energy loss that frictional resistance brings.
E dispatcher selects suitable schedule job route, is committed to management personnel's examination & verification, and management personnel graphically change
Mode, after auditing work flow, it is possible to achieve assigning online of work flow.
In above-mentioned steps a, each equipment base attribute such as table 2 below:
Table 2
The present invention realizes optimizing scheduling with a kind of network algorithm-extended state task network (ESTN), can be by computational reasoning
Time restriction is within 5 seconds.The mode that the inventive method is graphically changed is scheduling instruction examination & verification, and realizes assigning online, can
Reduce scheduling error, improve work efficiency.
The hardware configuration of system involved in the present invention is as shown in the figure.Machine room in control centre configures a station server, fortune
Row " optimizations of tank field oil transportation job scheduling " server version, by real-time from tank field (crude oil tank farm and product oil tank field) of collection
Data, the upstate of the current each equipment of real-time rational analysis, dispatcher uses C/S version client to be scheduling the rule of operation
Drawing and examination & verification, other staff can pass through B/S client, check the practice condition of operation with the form of log-on webpage.
Scheduler module is divided into work flow planning, work flow examination & verification and assigns two stages.
Work flow is planned: specified initial plant by dispatcher, through equipment, end device, with shortest path, experience
Minimum nodes, single line/two-wire are constraint, and the upstate of equipment is input, by calling inference engine, obtains optimal scheduling road
Line, i.e. work flow.
One dispatcher can select suitable work route, clicks on " submitting examination & verification to ", is committed to management personnel's examination & verification.
After management personnel are by auditing work flow, it is possible to achieve assigning of work flow.
The client developed, existing B/S framework, it is simple to user uses the arbitrary computer on Office Network in enterprise, i.e.
Can be appreciated that tank field schedule job implementation status, it is adaptable to management personnel；There is again C/S framework, enable users to check schedule job
Detailed operation conditions, it is adaptable to dispatcher, technique person.
The relevant technology contents do not addressed in aforesaid way is taked or uses for reference prior art to realize.
It should be noted that any equivalent alternative under the teaching of this specification, done by those skilled in the art
