Description

Automatic work order generation method
Technical Field
The invention relates to the technical field of intelligent operation and maintenance management platforms, in particular to an automatic work order generation method.
Background
With the iterative upgrade of communication technology and the rapid development of artificial intelligence technology, the BIM, GIS and Internet of things technology has been widely applied to large-scale infrastructure projects. The mode of unified management of the client operation logistics of hospitals and universities is generally that a logistics intelligent operation and maintenance management platform is adopted, real-time operation sampling data of field equipment verification is used as a basis, the energy utilization efficiency is improved, and the logistics work is uniformly allocated and managed. In the operation of back office wisdom operation and maintenance management platform, not only the operation and maintenance management to equipment, work order type wherein contains to report for repair, transport, patrols and examines, still supports to dispose other business types, considers that back office staff is many older, and is not too much understood things such as program application, cell-phone input, uses relatively difficultly, and pronunciation are reported for repair and can be reduced the system and use the degree of difficulty. The traditional work order is generally submitted by filling in the work order through a web page and an app or produced by manually inputting the work order into a system after being sent to a call center through a telephone. The methods have the problems of low efficiency, synchronous work of personnel in the call center and very large workload. The work order automatic generation method is needed, so that the work efficiency is greatly improved when the work order automatic generation method is used, and the work pressure of call center personnel is greatly reduced due to asynchronous auditing of the call center personnel.

Step two: error correction of the work order field; error correction is carried out on the entity words extracted from the work order fields by adopting an error correction algorithm based on a knowledge base; the knowledge base comprises knowledge points and basic knowledge points generated by the system platform in the using process; the system uses the knowledge points of the generated knowledge base to obtain entity words input by a work order and the entity words generated in the using process of the system as voice training corpora to obtain related user information, product information, position information and equipment information in the system; the error correction of the entity words extracted from the phonetic work single segment also comprises homophone error correction, Pinyin flat tongue-curled tongue corresponding relation error correction and nasal sound error correction.
Step three: different types of work orders are automatically generated; the work order types include: reporting a repair work order, a transport work order, a patrol work order and an after-sale operation and maintenance work order; after the work order is generated, the work order processing system informs a dispatcher through a message center, the dispatcher audits the work order, scores the generated work order according to a preset rule, and if the score is lower than a preset value, the dispatcher corrects the work order by listening to a recording recorded by the work order.
Step four: and informing the checked and dispatched work order to the corresponding order taker and the next processing person in a short message and WeChat mode.
Further, the entity words extracted in the step one comprise words of people, telephone, places, departments, objects, units and quantities, and corresponding attributes are given to the work order.
Further, the knowledge point and the basic knowledge point of the knowledge base in the error correction algorithm based on the knowledge base come from a customer information system, and comprise user names, telephones, organizations and department related information in user management; asset name from fixed asset management, location information for space management, and information related to repair person, repair object, repair location, carrier start and destination location, and carrier content of the service center worksheet; from the speech parsing error correction rules. The system information is very accurate linguistic data, so that the natural language processing of the system is more accurate.
Further, the scoring of the generated work order in the third step is specifically as follows: in the I-shaped single-field error correction stage in the step two, if the fruit body word is a word existing in the database, the word is directly used; if the word does not exist, replacing the word according to the score highest by the confusable pronunciation accumulated in the knowledge base, and counting the error rate of the whole text; error rate calculation formula: error rate = number of corrected words/number of full text participles 100%.
Further, the method also comprises the following step five: and optimizing a database, adding 1 point to the word replacement score of the pronunciation which is easy to be confused in the work order which is manually checked and passed, and recording the word replacement score into an error correction score table in a knowledge base to finish one positive feedback.
Further, the automatic generation of different types of work orders in the third step specifically includes: and (4) taking the accumulated work orders as a corpus, generating a classification model through machine learning, and identifying the type of the work orders.
3. Has the advantages that:
(1) the automatic work order generation method provided by the invention is simple, easy to use and high in efficiency through voice input.
(2) The work order is asynchronously audited through the call center before being sent to the submitting person, so that the pressure and the cost can be reduced.
(3) After the knowledge base is loaded, the accuracy of work order text analysis is greatly improved, the natural language processing of a proprietary system higher than the news flyover and Baidu is aimed at, and the accuracy is higher and higher as the use time of the system is advanced and the more the knowledge base is accumulated.
(4) The invention adopts the knowledge base to correct errors, can realize the recognition errors of polyphones, introduces pinyin full spelling check to correct errors, and further improves the accuracy.
(5) The accumulated data can be automatically classified through a machine learning model, and the automatic order dispatching algorithm can realize the functions of voice input and automatic order dispatching, thereby saving labor and time cost.
