Technical field
The present invention relates to machinery manufacturing industry, network and communication technology, technical field of information processing, belong to information acquisition and signal processing method in manufacturing execution system, be specifically related to a kind of batch workpiece digital control processing progress automatic acquiring method based on Multi-information acquisition.
Background technology
Job shop workpiece processed the current processing tasks of actual processing progress information feed back complete situation, the processing progress state of workpiece, reflect task matching and the processing situation of each lathe in workshop, reflect the information such as the situation that the processing characteristics of manufacturing enterprise's existing equipment and efficiency, the machining precision of part and order product complete, these data messages are bases that manufacturing technology planning personnel and production management dispatcher optimize production management and scheduling process, and client also needs the practice condition understanding order at any time in addition.Modern Manufacturing Enterprise must have rapid reaction to these uncertain factors and processing power, could maintain and improve the service competitiveness of modern enterprise like this.The processing progress status information of workpiece must be gathered, grasp the processing progress information of workpiece with the management of the operating personnel and enterprise that facilitate workshop and dispatcher in good time, also facilitate client to inquire about order implementation status at any time simultaneously.
The information acquisition of traditional mode of production processing progress mainly relies on operating personnel and carries out estimating, checks, adds up, hand filling paper document.This mode relies on manual manipulation, and personnel fill in inefficiency, and action repeats loaded down with trivial details, and the accuracy of information is affected by human factors, and unstable and data are unfavorable for transmission and share.In addition, paper document is easy to damage, and preservation and the inquiry difficulty of data are relatively large; And often there will be the phenomenon that multiple different workpiece is processed within a period of time on a machine tool in workshop, this also brings certain complicacy to statistics simultaneously.Along with the raising of the production automation level of modern enterprise, enterprise has extensively adopted computing machine process and manage production, and this complicate statistics mode can not meet the needs of modern enterprise.In addition, at present, although in the workshop that partial automation degree is higher, adopt in bar code, RFID, PLC, NC code and inserted the modes such as macro instruction, achieve the automatic collection of production and processing progress msg and report, but said method is all the simple number of packages gathering accumulative processing, and normal process number of packages concrete in processing, important progress msg such as processing number of packages, certified products number etc. of doing over again are difficult to automatically add up, this just can not well for the optimizing operation of enterprise provides support.
Summary of the invention
For current workshop work pieces process progress msg mainly by complicate statistics, although by bar code, RFID, PLC, the progress msg that the modes such as macro instruction obtain processing is inserted in NC code, but because NC Machining Process exists trial cut, do over again, the Various Complex situation such as to scrap, usually can cause the redundancy of processing quantity statistics, cause the problems such as manufacturing schedule acquisition of information is inaccurate, the object of this invention is to provide a kind of data feedback timely, statistics accurately, statistical content enriches, reduce the batch workpiece digital control processing progress automatic acquiring method based on Multi-information acquisition of human cost.
Realize above-mentioned purpose, the present invention adopts following technical scheme: a kind of batch workpiece digital control processing progress automatic acquiring method based on Multi-information acquisition, it is characterized in that, according in batch workpiece NC Machining Process, to the processing start and stop information comprised in numerical control of machine tools program, the quality information that the power information of process and workpiece sampling observation obtain carries out the fusion treatment of multi information, the processing progress information obtain accurately, enriched.
Further, the step of described automatic collection progress msg is:
1. utilize computing machine or built-in terminal, gather the processing start and stop information in lathe numerical control program by interface routine, circulating start and outage is then actual adds number+1;
2. in process, process the power information of this workpiece by network service Real-time Collection and carry out analyzing and processing, and comparing with power information standard: if be in the scope of normal process, then normal process number+1; Otherwise do over again and add number+1;
If also do not arrange power information standard, then current workpiece is tested, if qualified, then using the power information standard that the power information of this workpiece compares as following process;
3. by the quality information that network service acquisition quality testing obtains, carry out the judgement of quality state thus obtain certified products number in process, scrap number, need do over again and add the statistics of number;
4. comprehensive 1. walk and 3. walk, the 1. step obtain the actual processing quantity of this subtask, the 2. step be 1. walk to the actual processing quantity obtained to classify more accurately, by carrying out to the power information of each workpiece of processing the quantity that analyzing and processing obtains normal process part and workpiece of doing over again in actual processing work, 3. walk the quality condition by the actual workpiece of this task of workpiece quality acquisition of information, obtain the certified products number of workpiece in this task, scrap number, need do over again and add number;
5. add with certified products number/plan the completion rate that number obtains this processing tasks;
To sum up, can be obtained the following progress msg in process by this method: actually add number, certified products number, normal process number, does over again and adds number, need do over again and add number, scrap number, processing tasks completion rate.
Compared to existing technology, the present invention has following beneficial effect:
1, the inventive method is simple to operate, stable and cost is lower, does not affect normal process.
2, it is timely that the present invention has data feedback, statistics accurately, the advantages such as statistical content is abundant, start and stop information will be processed, power information and quality information carry out the progress msg that Multi-information acquisition process collects and not only comprise actual processing number of packages, and comprise normal process piece count, to do over again processing work quantity, certified products quantity, scrap quantity and the information such as quantity of need doing over again, this can provide support to the management and control ability of production scene and the optimizing operation of job shop for improving enterprise, also client is conveniently allowed to monitor the implementation status of order at any time, improve the service ability to client.
3, process start and stop information, collection and the analysis of quality information and power information all can adopt automated software to carry out online, and therefore this method is adapted at applying in automated manufacturing system.
Through practice test, the method is effective and feasible.Utilize the problems such as solution manufacturing schedule information extraction difficulty, accuracy are difficult to guarantees, information poor real, easily make mistakes by the present invention, waste of manpower resource, thus improve enterprise to the management and control ability of production scene and the increase performance of enterprises.
