Description

On-site data acquisition system and method based on mobile Internet technology

technical field

The present invention relates to a data collection system and method based on mobile Internet technology, in particular to a field data collection system and method based on mobile Internet technology.

Background technique

In industrial production, transportation, public utilities and other industries, there are a large amount of on-site data that cannot be collected by automated measurement and control systems, such as on-site quality inspection information in workshops, on-site installation and commissioning, logistics and warehousing information, transportation information, equipment inspection information, Meter reading information, etc. Examples are as follows:

(1) On-site quality inspection in the workshop: The conventional practice is that the quality inspection personnel take the relevant quality record card to the workshop for on-site inspection and record the inspection data, and then enter the computer system after returning to the office. Such a management method is not only inefficient, but also lacks real-time performance. , will lead to secondary entry errors; and the on-site data collection work cannot be supported by detailed design and production information and operating instructions, which will easily lead to a process out of control.

(2) Installation and commissioning of products: The installation and commissioning of large or professional machinery and equipment is extremely important, and the importance of product installation is no less important than that of product manufacturing. In the installation and commissioning of each use site, it is necessary to measure, record, and save a large amount of installation technical index data, and also need to obtain detailed product technical information or installation instructions. The current product installation management methods cannot achieve real-time and interactive installation process management. , As a result, the use of many instruments and equipment is greatly affected by unqualified installation and commissioning.

(3) Equipment inspection, meter reading, etc.: In many industrial productions, especially in process industries, production safety is the primary concern of enterprises. In order to avoid accidents, in addition to using the DCS distributed control system to monitor various on-site instruments and working conditions in real time, the enterprise must also establish a manual regular inspection system to monitor important, critical or difficult production links and production The status of the site and production equipment is manually inspected and recorded as an important means of accident prevention, so as to ensure timely grasp of the site situation and prevent various accidents from happening. However, in actual work, it is difficult to informatize equipment inspection records and realize real-time interaction and integration with computer systems, becoming an information island, and there are even many phenomena that do not go to on-site inspections and falsify on-site data, which leads to some situations that could have been avoided. Accidents happen from time to time.

For enterprise informatization, on-site data collection is the so-called "last mile" problem, that is, enterprises may spend huge sums of money to establish management information systems such as PDM\CAPP\ERP, hoping to achieve efficient production and management. However, because these information systems lack the methods and capabilities to collect various on-site data in real time, just like after getting off the expressway network, although the distance to the final destination is only 1 kilometer, due to the bad roads, it takes a lot of time and reduces the The informatization effect and level of the entire enterprise.
