Description
Technical Field
The invention relates to the field of numerical control machine tool management, in particular to the field of reliability tests, and specifically relates to a system and a method for realizing the reliability test management of a numerical control machine tool based on an industrial internet.
Background
Numerical control machines play an important role in industrial manufacturing, and the advanced level thereof represents the comprehensive strength of a country. With the development of numerical control machine tool technology in China, the reliability research work of the numerical control machine tool becomes more and more important. Because the reliability research of the numerical control machine tool in China starts late, most enterprises pay less attention to the reliability data collection work, and the reliability research level of the numerical control machine tool in China has a certain gap with the foreign level. For production and manufacturing enterprises, the normal operation of the numerical control machine tool has an important influence on the benefits of the enterprises. In daily use, if a scientific quantitative method can be used, the running condition of the machine tool can be known at any time, and the reliability of the machine tool is judged, thereby being beneficial to the improvement of the economic benefit of enterprises. According to the national standard GB/T23567.1-2009 numerical control machine reliability assessment 1 st general rule, the reliability of the machine tool is calculated, and if a test field test method is adopted, each model machine needs to be accumulated for 500 hours; if the field tracking statistical test method is adopted, the test time of each prototype reaches 2000 h. In the traditional test mode, enterprises hire professional technicians to a machine tool deployment site, and for each machine tool fault, a paper fault analysis report, a fault record table and a test operation record table need to be manually filled. Such purely manual data collection and subsequent statistical analysis requires a large amount of manpower, thereby increasing enterprise-related costs, and the heavy manual paper data collection work also tends to make it difficult to ensure the quality and integrity of the collected data. Because the manual paper record is the only record, the subsequent dispute and lack of other historical records as the evidence of auditing and verification can only be retested. Meanwhile, for the judgment of the fault, an experienced expert is needed to analyze the cause of the fault and judge whether the fault is brought into the calculation of the reliability index, but for the whole industry, related experts belong to scarce social resources, and for most enterprises, the adoption of the expert to carry out the full job to the site also increases higher personnel cost and travel cost. Therefore, reliability tests are less performed by vast numerically-controlled machine tool equipment suppliers and end-user enterprises in China at present, and the reliability tests are very unfavorable for finding potential problems and improving the direction of the machine tool industry in China and improving the level of the whole manufacturing industry. Therefore, methods and means for improving the test efficiency and ensuring the test quality are needed.

In a specific embodiment of the invention, a test management platform based on an industrial internet technology is designed for a reliability test of a numerical control machine tool, a tool for acquiring, arranging and analyzing test data is provided, automatic data acquisition and manual data entry of equipment are organically combined, a mobile office and multi-person cooperation mode is provided, the accuracy and the integrity of data acquisition are improved, and scarce industrial expert resources are fully utilized to complete the examination of the data and the automatic generation of reports.
A reliability test management platform of a numerical control machine tool can be used for collecting, auditing and analyzing data in a test, automatically generating a test report and managing test personnel, and can improve the accuracy and integrity of data collection and realize automatic analysis of the data and remote cooperation of multiple persons in the test by utilizing the actually collected machine tool running state, alarm data and mobile office technology. Data acquisition software or hardware modules need to be deployed, and the operating state of the machine tool and alarm data are acquired to a platform in real time to serve as digital evidence for subsequent data auditing and analysis. Mobile office client software is required to be provided to support various participants of the test to enter, audit and analyze data anytime and anywhere and to download test reports. And a test report which accords with the method and format specified by the national test standard can be automatically generated according to the checked data.
The object of the invention is achieved by the following measures:
firstly, the core of the technical scheme of the invention is that a numerical control machine reliability test management platform based on the industrial internet needs to be erected. The platform supports mobile office, so that experimenters in different places can conveniently enter and audit data. The platform can automatically acquire the running state and the alarm data of the numerical control machine tool as a test object at the same time, and the running state and the alarm data are used as a basis for checking the manually input test data. The platform has certain data analysis capability and can automatically generate a test analysis report meeting the national standard.
Secondly, one of the bases of the implementation of the technical scheme of the invention is to erect external data acquisition hardware or install data acquisition software in a numerical control system of the numerical control machine tool so as to acquire real-time data of the running state, alarm and the like of the machine tool and transmit the data to the test management platform. The collected data is mainly used for original evidence to review manually entered test data.
Thirdly, one of the bases of implementation of the technical solution of the present invention is mobile office technology. Client software connected with the test management platform is installed on a mobile phone and a personal computer, so that a responsible person for hosting a test and participators participating in data input can conveniently input, audit and analyze data at any time and any place, and test reports are issued and test team personnel are managed.
The basic principle of the reliability test of the numerical control machine tool is as follows:
the reliability evaluation index mainly comprises average fault interval time and average repair time. Mean Time Between Failure (MTBF) is an average of working time between two adjacent faults, and a point estimation value is obtained by dividing accumulated working time of the test equipment in a test period by an accumulated fault number, and if all the machine tools in the test have no fault by the end of the test, the point of the MTBF is estimated to be three times of the accumulated test time. Mean Time To Restoration (MTTR) is an average of the time required from the fault finding to the restoration of specified performance, and is obtained by dividing the cumulative repair time of the test equipment over the test period by the cumulative number of faults.
The average fault interval time and the average repair time need to be judged before calculation, and the faults of the machine tool need to be counted. According to the national standard, only the correlation fault needs to be included in the calculation of the reliability evaluation index. Non-related faults such as faults caused by misuse, misoperation and other reasons which are not the cause of the machine tool itself, and preventive maintenance according to a prescribed program should be excluded when calculating the reliability evaluation index, but should be recorded. Further, since the determination of the failure should be based not on the occurrence of the failure but on the cause of the occurrence of the failure, a plurality of abnormalities of the machine tool may be finally determined to be calculated as only one failure entry index, and one abnormality may be broken down into a plurality of failure entries. Therefore, the determination of the failure is complicated, and cannot be performed without human experience at present.
In summary, a complete reliability test management platform needs to provide a manual entry interface for three types of data information, namely test time intervals, fault records (including associated faults and non-associated faults) and preventive maintenance, and calculate reliability indexes for the acquired data according to a specified method.
In order to meet the requirements of data acquisition, auditing, analysis and cooperation in a reliability test, the invention has the specific implementation scheme as shown in fig. 1, and external data acquisition hardware is erected or data acquisition software is installed in a numerical control system of a numerical control machine tool so as to acquire the running state of the machine tool and real-time data of alarm and transmit the real-time data to the test management platform.
Meanwhile, test management software is deployed in the test management platform to provide the following functions:
(1) multi-user collaborative entry of data
The test can be completed by cooperation of multiple platform users. The user who creates the test is the responsible person of the test, and has the management authority for the equipment and other participants aiming at the test and the authority for auditing the input data. The responsible person can join other platform users in the experiment, and the participant who joins in the experiment has the authority of entering data. The user can log in the test management platform at various clients (including but not limited to web pages, desktop, mobile applications and the like) of the test management platform to complete data entry operation.
(2) Providing machine tool data assist determination
Aiming at the problem that an expert not on site is difficult to judge the reasonability of data, a test platform provides a machine tool running state and alarm data as a basis for assisting judgment, and the running state of the machine tool in each test period is drawn into a time axis to be displayed in the details of the test period; and the comprehensive judgment can be carried out by combining data in functions of equipment monitoring, alarm logs and the like of the test management platform.
(3) Test log record
The operations of creating, modifying, submitting, deleting and the like of each piece of test data are recorded in the test log, so that data problems are found out according to the records, the possibility of malicious tampering of the data is obviously reduced, and the whole test process is transparent and fair.
(4) Test tail truncation reminder
Before a reliability test is performed on a numerically controlled machine tool, it is usually necessary to determine a test end condition, i.e. a truncation condition. In the platform, because data are all recorded into the database, the data such as test time, fault number and the like can be conveniently accumulated and calculated in real time for a user, and tail-cutting reminding is provided. When the traditional paper method is adopted for recording, the accumulated calculation workload of the data is large, and the test platform described herein completely hands over the part of the work to the server. The truncation mode is divided into timing truncation, fixed number truncation and sequential truncation. Selecting timing truncation, setting truncation duration, and if the total duration of the approved test period reaches the truncation duration, recording data again, and reminding the system that the truncation duration is met; selecting a fixed number of truncation and needing to set a truncation fault number, and when the approved associated fault number reaches the truncation fault number, if data is recorded again, the system can remind that the truncation fault number is met; if the sequential truncation is selected, the truncation condition is not preset, and whether the test can be ended or not is judged while testing.
(5) And (3) generating an experimental report:
when the test responsible person judges that the collected data meets the test requirement, a report can be generated on the test platform, and the generated report can be downloaded by all the persons in the test. The report includes the test data and the calculated key assessment indicators.
The user of the test management platform can perform on-line test operation according to the following steps, wherein the method comprises the following steps:
(1) a new test is carried out:
a test management platform user is used as a test responsible person to newly establish a reliability evaluation test, edit related information, add a machine tool required to be investigated by the test as a test work object, and take platform account numbers of other persons required to participate in the test as test work participants;
(2) entering data:
all participants in the test can enter information of a test period, fault records and preventive maintenance during the test, such as start and end time, fault/maintenance description and the like;
(3) and (4) auditing data:
for each officially submitted test time period, fault record and preventive maintenance, a test responsible person judges whether the operation is reasonable or not and carries out approval or return operation by combining the time axis data of the operation of the equipment at each time period given by the platform and the equipment operation state and alarm historical data stored in the test management platform;
(4) and (3) generating a report:
once the final audited data is accumulated to meet the requirements of the test, the test principal can initiate the generation of a test report.
The embodiment of the invention is the cloud application of 'reliability evaluation' on an 'NcCloud dimensional macro cloud industrial Internet platform' (hereinafter 'dimensional macro cloud') of Shanghai dimensional macro electronic technology corporation (hereinafter 'dimensional macro share'). The Wei macro cloud platform provides a data acquisition software module for accessing equipment data to a cloud, and the software module can be built in a numerical control system for Wei macro share production. As long as the machine tool of the numerical control system of the Wei-hong shares is adopted for networking, the running state and the alarm data of the machine tool can be automatically uploaded to the Wei-hong cloud. After the buyer and the seller of the machine tool decide to carry out the reliability test, a third-party industry expert can be hired to be used as a test principal to host the test. The test responsible person and the production personnel on duty on the machine tool site can freely register the Weihong cloud account as the participants of the test. After logging in the Weihong cloud, a test responsible person can add reliability evaluation cloud application, establish a new test and add all participants into the newly-established test. Therefore, under the condition that a test host does not need to go to the site of the machine tool, the site production personnel can be used as a test participant to record the data of the production time interval, the fault time interval and the preventive maintenance time interval of the machine tool according to the condition of the machine tool. The test host can make analysis and judgment in different places according to the machine tool running state and alarm data acquired by the platform, so that the authenticity of the manually input test data is scientifically and strictly checked, the reasons of the faults are analyzed, the number of the faults is confirmed, and the reasonable judgment of whether the test is finished is finally made. After the test is finished, the platform can automatically generate an experimental report meeting the requirements of Chinese national standard methods and styles according to all collected and input data, and the experimental report can be downloaded and signed by a test responsible person to take effect.
The system and the method for realizing the reliability test management of the numerical control machine based on the industrial internet have objectivity, and the industrial internet platform based on the data acquisition of the machine tool equipment guarantees that the equipment data is completely and objectively stored during the test, so compared with the original pure manual recording of test data, the system and the method have the characteristics that the data cannot be counterfeited and the conclusion can be audited afterwards. Objectivity fundamentally ensures the accuracy and integrity of all raw data. The invention has the advantages that the invention has the collaboration, and as the functions of data entry, examination and approval and the like are provided on the mobile application or the client, all participants and responsible persons in the test can carry out related work at any time and any place, the related travel cost is saved, and the expert in charge of the test can also use the precious time for the examination and analysis of the test data instead of the travel traffic.
