Industrial Internet control acquisition system

Abstract

The invention relates to an industrial Internet control acquisition system. The system comprises a cloud platform, several collectors and an EtherCAT main station. The cloud platform is wirelessly connected to the several collectors through NB-IOT to realize data uploading or issuing with low power consumption and a high coverage rate. Each collector is correspondingly connected to one or more external devices. The EtherCAT main station is used to realize acquisition and transmission of external device data and bidirectional communication of remote control. The collectors and the external devices use the EtherCAT as a data interface to carry out extremely fast communication. The external devices include an EtherCAT slave station device and a device matching with an I / O input / output interface. The collectors include an EtherCAT unit, an MCU control unit, an NB-IOT transmission unit, a serial communication unit, an external interface unit, and a data storage unit. The system is mainly used to provide time delay without any communication protocol conversion. Especially for device data collection in a closed indoor environment with a poor signal, the control acquisition system has a high speed, low cost, a high practical value and a wide application range.

Description

technical field [0001] The invention relates to an acquisition system, in particular to an industrial Internet control acquisition system. Background technique [0002] In the traditional machinery manufacturing industry, the production batches are small, the production is repeated, the efficiency is low, and the human and material resources are wasted. What is more serious is that the products cannot be reasonably divided, the production cannot be rationally arranged, and specialized production cannot be formed, resulting in the production concentration of the machinery manufacturing industry. Low level of specialization. As a result, many products suitable for mass production have not reached the economic scale standard for a long time, and the scale benefit advantage of the machinery manufacturing industry has not been fully exerted. Therefore, in order to improve the comprehensive productivity of the factory, many factories now hope to transmit the operation data of the...

Problems solved by technology

However, the range of data collected by these methods is limited, and the effect is not ideal in a closed indoor environment, and there is often a delay caused by communication protocol conversion between network communication modules and devices, which affects the efficiency of the entire collection system
