Description

Logistics equipment fault prediction terminal based on edge calculation
Technical Field
The invention relates to a logistics equipment technology, in particular to a logistics equipment fault prediction terminal based on edge calculation.
Background
With the realization of the intellectualization of the operation control system, at present, the gradually improved computer control technology and the integrated sensing technology are widely applied in the logistics equipment industry, and the configuration of advanced electronic control and computer operation systems is very common. The structures of a mechanical system, an electrical system, a hydraulic system and a control system of the logistics equipment are gradually complicated, and the economic benefit and the environmental effect are directly influenced if the equipment can safely, continuously and stably run. Because of the limitation of production conditions and production plans in production fields, in order to accurately, efficiently and conveniently diagnose faults of logistics equipment, engineering technicians must fully utilize technical conditions and field information of the engineering technicians, assemble and disassemble equipment as little as possible, shorten maintenance time, save maintenance working hours and maintenance cost, adopt the simplest technical means to quickly find out fault parts, accurately diagnose fault reasons and repair, timely recover normal operation of a system, and ensure that similar faults do not occur in future.
Operation data, maintenance data and the like of the logistics equipment are stored in the cloud to form industrial big data, and faults of the equipment can be predicted in the cloud based on the data. However, the data is transmitted to the remote cloud center for storage and calculation, which may cause too much energy consumption of the GPRS module carried by the logistics equipment itself and premature failure, and also bring huge traffic charges, on the other hand, when using cloud services, a large amount of data needs to be transmitted and received, which may consume a large amount of network bandwidth, which may cause an I/O bottleneck between the data center and a terminal carried by large-scale engineering mechanical equipment, thereby causing problems of greatly reduced transmission rate, even service interruption, and the like.
On the other hand, with the development of a ubiquitous intelligent terminal, various heterogeneous intelligent or non-intelligent network terminal devices are provided, although the size of the terminal devices becomes smaller and smaller, the resources in the aspects of computing, storing and the like of the terminal devices become stronger and stronger, which results in surplus and idle of the resources of the terminal devices. Secondly, most of the existing intelligent terminals, especially the intelligent mobile terminals, are equipped with or have some or a plurality of sensors, which can sense the position (GPS) of the intelligent terminal or the surrounding environment state, and the collection of the position or environment information will generate a large amount of sensing data, if the ultra-large scale sensing data are all uploaded to a cloud computing large-scale data center for processing, the processing will not only waste time and labor, but also lose the meaning and value of utilization even because the data processing is not in time. Thirdly, with the development of hardware technology, the capability of the edge network device becomes stronger, and the enhancement of the processing and storage capability of the edge network access or routing device makes it possible for the user to implement the value added service required by the user by using the edge network device.
In this case, data needs to be processed at the edge to shorten the response time, so that data processing is more efficient and the network pressure becomes smaller. The edge computing model migrates part or all of the computing tasks of the original cloud computing center to the vicinity of the data source for execution, so that the data transmission bandwidth can be reduced, the privacy data can be well protected, and the risk of privacy disclosure of the terminal sensitive data is reduced.
Therefore, the logistics equipment fault prediction terminal based on edge calculation is designed and developed, and the data is preprocessed on the side close to a data generator to complete the prediction of the logistics equipment fault.
