IoT (Internet of Things) service terminal for factory

Abstract

The invention discloses an IoT (Internet of Things) service terminal for a factory. The IoT service terminal comprises a data acquisition unit which comprises a CPU (central processing unit) as well as a keyboard, a battery, a flash, an RS232 (recommend standard 232) serial port, an Ethernet module, an I / O (input / output) acquisition module, a clock and a display screen which are respectively connected with the CPU. The IoT service terminal for the factory has the functions of receiving instruction information about production service plan as well as acquiring, uploading and processing information of a production field and can be used for acquiring data such as equipment state, production Takt time, alarm information, equipment utilization rate and the like, thereby saving labor and reducing the data acquisition cost.

Description

technical field [0001] The present invention relates to the technical field of digital signal processing and control of equipment in the manufacturing industry, in particular to a factory Internet of Things business terminal and an automatic measurement unit and method for calculating global equipment efficiency (OEE), a key performance indicator of enterprise production, using the terminal. Background technique [0002] The traditional production process adopted by my country's manufacturing industry for many years is characterized by "top-down" production according to plan. To put it simply, it is from the planning layer to the production control layer: the enterprise makes a production plan according to the order or market situation—the production plan arrives at the production site—organizes the production—product delivery. The focus of enterprise management information construction is also mostly placed on the planning layer for production planning management and genera...
