Abstract
The invention relates to a method for controlling a material transporting system of a stock yard of a large-scale industrial enterprise. Flow equipment is constructed to select the selectional relation between a matrix storage flow and the equipment; a line number of a matrix is used as a flow number; and a row number is used to identify the equipment. Then the flow number is input; a flow equipment optional word is extracted from a flow equipment selection matrix; the flow equipment optional word and an equipment status word are subjected to logical operation; a calculation result is used tojudge whether the flow is ready; if the flow is not ready, the flow number is re-input to select other flows; if the flow shows ready, the flow equipment optional word and the equipment status word are assigned to an equipment interlocking control module; and an equipment interlocking control program outputs the equipment status word. The equipment status word transmits a startup control signal and a stoppage control signal of the equipment, thereby completing the flow control. The method can save the investment of a secondary computer for controlling materials in the stock yard, can be conveniently realized through programming in a PLC or other logical controllers and shorten time for software development.
Description
Technical field
The present invention relates to the materials in stock yard induction system control of large-scale industrial enterprise.
Background technology
The method of stock yard flow process control at present mainly contains two kinds, and a kind of is to utilize second computer to adopt database and the control of advanced language programming realization flow, and this method mainly is applicable to large-scale stock yard, system complex, and equipment is many, and flow process is many; Another kind is to programme one by one according to flow process, and one section program of a flow process realizes that this method mainly is applicable to some small-sized stock yards, and equipment is few, and flow process is few, and system is simpler, is not suitable for large-scale stock yard.
The two-level computer system that first method adopts is more by external introduction, manpower and fund that independent development drops into are many, domestic industry industry restructuring at present, and scope of the enterprise is increasing, small-sized stock yard is eliminated gradually or transforms, and does not generally adopt second method.
Summary of the invention
Technical matters to be solved by this invention provides a kind of flow path control method for material handling system of stock yard of not only saving investment but also being easy to realize.
For solving the problems of the technologies described above, the present invention proposes a kind of flow path control method for material handling system of stock yard, it may further comprise the steps:
A, structure flow sheet equipment selection matrix, the row of described flow sheet equipment selection matrix number is a flow process number, and row number are that device identification, matrix interior element are called flow sheet equipment and select word, it is switching value that described flow sheet equipment is selected the value of word, and this switching value represents whether certain flow process number chooses certain equipment;
B, input flow process m, m is a variable;
C, read the capable described flow sheet equipment of the m of described flow sheet equipment selection matrix and select word,
Do d, the equipment that flow process among the step b is chosen judge that this equipment is in ready state?
(i) if then continue to judge that this equipment is in running status?
(ii) if then return step b;
(ii) if not, then flow sheet equipment is selected word and device status word to compose to the chain control module of equipment, the chain control module output device of described equipment control word, the start and stop control signal of device control character transfer equipment, thus realization is to the control of flow process; Return step b then;
(i) if not, then return step b.
The know-why of above-mentioned structure flow sheet equipment selection matrix is flow process control to be decomposed into three relations to handle, be i.e. the relation of flow process and equipment, the relation between the flow process, the relation between the equipment.Relation between flow process and the equipment mainly is meant the choice relation between flow process and the equipment, relation between the flow process mainly refers to the interlocked relationship between two of shared some equipment or many flow processs, and the relation between the equipment mainly is meant the upstream and downstream linkage relationship of equipment in the whole conveying flow network.Described flow sheet equipment selection matrix (FlowDeviceSelect[m, n]) choice relation between Stored Procedure and the equipment, the row of matrix number (m) is as flow process number, row number (n) are used for marking equipment, FlowDeviceSelect[21 for example, 30]=No. 30 equipment of 1 No. 21 process selecting of expression.
Adopt flow control method of the present invention, a logistics control second computer investment can economize in raw materials.The realization of can easily programme in PLC or other logic controllers simultaneously, the shortening software development time is a kind of stock yard flow process controlling schemes of economic and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is further described in detail.
Fig. 1 is a control flow synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, system begins, enter step 10, make up the flow sheet equipment selection matrix FlowDeviceSelect[m of two dimension, n] choice relation between Stored Procedure and the equipment, the row m of matrix is as flow process number, and row n is used for marking equipment, FlowDeviceSelect[21 for example, 30]=No. 30 equipment of 1 No. 21 process selecting of expression.
Enter step 11, input flow process m;
Enter step 12, read the capable described flow sheet equipment of m of described flow sheet equipment selection matrix and select word,
Step 13, the computing of employing matrix logic comes the interlocked relationship between the treatment scheme, and flow sheet equipment is selected word FlowDeviceSelect[m, n] and device status word DeviceReady[n] the logical computing,
Step 14, judged result and FlowDeviceSelectm, n] whether equate that step 14 is then returned step 11 if not.
Step 14 is if represent that then m flow process selected device all is ready to, continue step 15 then, again with FlowDeviceSelect[m, n] with device status word DeviceRun[n] carry out the logical computing,
Step 16, whether judged result equals " 0 ", and step 16 is then returned step 11 if not;
Step 16 is if represent that then m flow process selected device all less than operation, does not conflict with other flow processs, flow process permission startup;
Step 17, select word and device status word to compose flow sheet equipment to the chain control module of equipment, the chain control module of equipment is existing PCB, unified finishing comprises that the upstream and downstream of describing between all flow sheet equipments concerns, accepts process selecting information FlowDeviceSelect[m, n] and status information of equipment DeviceaRun[n], DeviceReady[n], output device steering order DeviceaStart[n], DeviceStop[n], DeviceEStop[n] function;
Step 18, the chain control module of equipment is to field apparatus control system output device steering order DeviceaStart[n], the start and stop of opertaing device; Then return step 11 then.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
