Description

Batch workpiece digital control processing progress automatic acquiring method based on Multi-information acquisition
Technical field
The present invention relates to machinery manufacturing industry, network and mechanics of communication, technical field of information processing, belong to manufacture and perform system Information gathering and signal processing method in system, and in particular to a kind of batch workpiece digital control processing progress based on Multi-information acquisition is certainly Dynamic acquisition method.
Background technology
Job shop has fed back the completion situation of current processing tasks in the reality processing progress msg of workpiece processed, workpiece Processing progress state, reflects task distribution and the processing situation of each lathe in workshop, reflects adding for manufacturing enterprise's existing equipment The information such as the situation that work performance and efficiency, the machining accuracy of part and order product are completed, these data messages are machine-building Process planning personnel and production management dispatcher optimize the basis of production management and scheduling process, and client is also required at any time in addition Understand the practice condition of order.Modern Manufacturing Enterprise must have the fast reaction and treatment energy to these uncertain factors Power, could so maintain and improve the service competitiveness of modern enterprise.The processing progress status information of workpiece must be gathered, with side The management of operating personnel and enterprise between convinent car and dispatcher grasp the processing progress information of workpiece in good time, while being also convenient for visitor Order implementation status is inquired about at family at any time.
Traditional mode of production processing progress information gathering relies primarily on operating personnel and is estimated, checked, counted, hand filling paper Matter file.This mode is operated by hand, and personnel fill in inefficiency, and action repeats cumbersome, and people is received in the degree of accuracy of information For factor influences, unstable and data are unfavorable for transmission and share.Additionally, paper document is easy to damage, the preservation of data It is relatively large with inquiry difficulty;And, often occur multiple different workpiece within a period of time simultaneously at one in workshop The phenomenon processed on lathe, this also brings certain complexity to statistics.As the production automation level of modern enterprise is carried Height, widely used computer is processed and manages production for enterprise, and this artificial statistical can not meet modern enterprise The need for industry.In addition, at present, although in partial automation degree workshop higher, using bar code, RFID, PLC, NC The modes such as macro-instruction are inserted in code, the automatic data collection of production and processing progress msg is realized and is reported, but the above method is all Simply simple collection adds up the number of packages of processing, and for specific normal process number of packages, do over again processing number of packages, certified products in processing The important progress msgs such as number are difficult to be counted automatically, and this cannot well for the optimization operation of enterprise provides support.
The content of the invention
Mainly manually counted for current workshop work pieces process progress msg, although can by bar code, RFID, PLC, Insert the progress msg that the mode such as macro-instruction obtains processing in NC codes, but there is trial cut due to NC Machining Process, do over again, report Redundancy that is useless to wait Various Complex situation, can usually causing processing quantity to count, causes manufacturing schedule acquisition of information inaccurate etc. and asks Topic, it is an object of the invention to provide a kind of data feedback in time, statistics is accurate, statistical content is abundant, reduce the base of human cost In the batch workpiece digital control processing progress automatic acquiring method of Multi-information acquisition.
Above-mentioned purpose is realized, the present invention is adopted the following technical scheme that:A kind of batch workpiece numerical control based on Multi-information acquisition Processing progress automatic acquiring method, it is characterised in that according in batch workpiece NC Machining Process, to being wrapped in numerical control of machine tools program The processing start and stop information for containing, the quality information of power information and workpiece the sampling observation acquisition of process carries out the fusion of multi information Treatment, obtains accurate, abundant processing progress information.
Further, the step of automatic data collection progress msg is:
1. computer or built-in terminal are utilized, the processing start and stop gathered by interface routine in lathe numerical control program are believed Breath, one cycle start and stop then reality processing number+1;
2. in process, the power information of the workpiece is processed by network service Real-time Collection and is analyzed and processed, And be compared with power information standard:If the scope in normal process, normal process number+1;Otherwise do over again processing number+ 1;
If being also not provided with power information standard, current workpiece is tested, if qualified, the workpiece The power information standard that power information is compared as following process;
3. the quality information that quality testing is obtained is obtained by network service, carries out the judgement of quality state so as to be added Certified products number during work, scrap number, the statistics of the processing number that need to do over again;
4. comprehensive the 1. walk to the and 3. walk, the 1. step obtain the reality processing quantity of the subtask, the 2. step be to the 1. The reality processing quantity that step is obtained carries out more accurately classification, and place is analyzed by the power information for processing each workpiece Reason obtains the quantity of normal process part and workpiece of doing over again in reality processing workpiece, the 3. step pass through workpiece quality acquisition of information sheet The quality condition of task reality processing part, obtains the certified products number of workpiece in the task, scrap number, and need to do over again processing number;
5. the completion rate that number obtains this processing tasks is processed with certified products number/plan;
To sum up, the following progress msg in process can be obtained by this method:Reality processing number, certified products number, Normal process number, processing number of doing over again, need to do over again processing number, scrap number, processing tasks completion rate.
Compared to existing technology, the present invention has the advantages that:
1st, the inventive method is simple to operate, stable and cost is relatively low, does not influence normal process.
2nd, the present invention has the advantages that data feedback is timely, statistics is accurate, statistical content enriches, and will process start and stop information, Power information and quality information carry out Multi-information acquisition and process the progress msg for collecting not only including reality processing number of packages, and And including normal process piece count, do over again processing piece count, certified products quantity, scrap quantity and the quantity that need to do over again etc. believe Breath, this can provide support, be also convenient for allowing to improve optimization operation of the enterprise to the management and control ability and job shop of production scene Client monitors the implementation status of order at any time, improves the service ability to client.
3rd, start and stop information is processed, the collection and analysis of quality information and power information all can online be entered using automated software OK, therefore this method is adapted to be applied in automated manufacturing system.
Through practice test, the method is effective and feasible.Using the present invention will solve manufacturing schedule information extraction it is difficult, The degree of accuracy it is difficult to ensure that, information poor real, easily make mistakes, waste of manpower resource the problems such as so that improve enterprise to production The management and control ability and the increase performance of enterprises at scene.
