Embodiment Construction

[0025] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but it is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be covered by the present invention. within the scope of protection.

[0026] The present invention provides a relay life prediction information collection system based on the Internet of Things, such as figure 1 As shown, the system includes three parts: an information collection unit, a cloud server, and a front-end interface. The information collection unit includes a sensor group, a microcontroller, a storage module, a data transmission module, and a power management module. The sensor group converts the measured current into a measurable voltage. The ADC is used to convert the voltage into a digital value that can be ...

Abstract

The invention discloses a relay service life prediction information acquisition system based on Internet of Things, and the system comprises three parts: an information acquisition unit, a cloud server, and a front-end interface, and the information acquisition unit is used for acquiring data of an equipment terminal and uploading the data to the cloud server; the cloud server is used for carryingout classified storage and analysis on the measurement data after receiving the operation data information, carrying out service life prediction according to a service life prediction model and providing an alarm function by combining the received data, and correcting a previous prediction result after new data is collected so as to perfect the service life prediction model; and the front-end interface is used for inputting, displaying and exporting relay information. Data are collected in a large range through the Internet of Things technology, and the problems that in existing relay servicelife prediction research, few experimental data are available, data acquisition is difficult, and the data breadth is not enough are solved.

Description

technical field [0001] The invention relates to a big data information collection system, in particular to a relay life prediction information collection system. Background technique [0002] As the most basic electronic control device, relays are widely used in all aspects of production and life. In a specific industrial system, the reliability of the relay affects the working state of the entire system, so the research on the life prediction of the relay is of great significance. The current research at home and abroad is basically divided into two directions. On the one hand, it is to analyze the change characteristics of the relevant working parameters of the relay to predict the service life. On the other hand, the method of sampling inspection is used to predict the overall life of a batch of products. [0003] Although there are many prediction methods for the life prediction problem, the current source of experimental data is mainly the manual experiment conducted ...
