Make and reduce oil transportation job scheduling error, improve work efficiency.
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.
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 one for crude oil
Tank field oil transportation job scheduling optimization method, can instruct and reduce scheduling error by Optimized Operation by the method, improve work efficiency.
A kind of method optimized for crude oil tank farm oil transportation job scheduling, comprises the following steps:
A uses C# language, and Visio carries out secondary development, carries out the graphical configuration of crude oil tank farm technique on this basis:
Carry out the drafting of process chart；Collect instrument, the information of equipment, carry out the base attribute configuration of tank, valve, pump, pipeline.
According to source difference, attribute is divided into static state and dynamic attribute.
B, by the creation data of production scene host computer, writes RTU (Remote Terminal Unit, remotely end by Ethernet
End unit, can be responsible for on-site signal, the monitoring and control of industrial equipment.RTU is the core constituting CIMS in Enterprise
Center device, is generally inputted/goes out module, microprocessor, wire/wireless communication apparatus, power supply and shell etc. by signal and form, by
Microprocessor controls, and supports network system).The data acquisition server newly increased in the present invention passes through RS-232 serial communication
Agreement reads data from RTU, and writes in SQL Server data base, thus is crude oil tank farm oil transportation job scheduling optimization system
System provides corresponding data.Data transmission between RTU to server of the present invention is unidirectional, it is achieved that system and production net
Physical isolation.
C reads real-time production data, in conjunction with manually arranging condition, specialist system judges each tank, pump, valve, the making of pipeline
With state (be included in state, malfunction, upstate), and write 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；Adjust
Joint 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 use shape
State.
D be manually specified operation start-stop apparatus, must through equipment, avoid equipment, based on the annexation of tank field equipment, knot
Close 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 in MATLAB based on BSTN net
The exploitation of algorithm bag.For the ease of application, algorithm bag is packaged into DLL form.Visual Studio development kit adds
Add and quote, appoint 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 and audits, the mode that management personnel graphically change,
After work flow is audited, 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 the time restriction of computational reasoning
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, improves work efficiency.
The hardware configuration of system involved in the present invention is as shown in Figure 1.Machine room in control centre configures a station server, runs " former
Oil transportation job scheduling in tank farm optimizes " server version, by gathering the real time data from tank field, real-time rational analysis is the most each
The upstate of equipment, dispatcher uses C/S version client to be scheduling planning and the examination & verification of operation, and other staff can be led to
Cross 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
Few node, single line/two-wire are constraint, and the upstate of equipment is input, by calling inference engine, obtains optimal scheduling route,
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.Pipe
After reason 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, Ji Keliao in enterprise
Solve tank field schedule job implementation status, it is adaptable to management personnel；There is again C/S framework, enable users to check the detailed of schedule job
Thin 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.
