Field programmable gate array (FPGA)-based industrial field temperature acquisition and alarm method and device

Abstract

The invention discloses a field programmable gate array (FPGA)-based industrial field temperature acquisition and alarm method. The method includes the following steps that: step 1, a host controls a field temperature acquisition module to perform filed temperature acquisition; step 2, the temperature acquisition module transmits acquired temperature data to the data processing and transmitting module of the host through a single bus; step 3, the data processing and transmitting module processes the temperature data and packs processed temperature data into a standard Ethernet packet, and the standard Ethernet packet is transmitted out through an Ethernet control module; and step 4, the data processing and receiving module of a client receives the Ethernet packet, processes and displays the temperature data and provides the temperature data for a display and temperature alarm module; and step 5, the display and temperature alarm module displays the temperature data and judges whether temperature exceeds preset temperature according to the temperature data, and emits alarm signals when the temperature exceeds the preset temperature.

Description

technical field [0001] The invention belongs to a temperature acquisition and alarm device, more specifically, an FPGA-based industrial field temperature acquisition and alarm method and device. Background technique [0002] The emerging temperature acquisition and alarm system requires high precision and long-distance transmission at the same time. Using FPGA and Ethernet can better meet these requirements, and it is small in size, light in weight, easy to modify, short in development cycle, easy to transplant and make corresponding Special ASIC and batch production have been widely used in the field of modern industrial temperature acquisition and alarm. [0003] With the development of science and technology and the continuous improvement of industrial automation level, the collection and transmission of industrial site temperature is becoming more and more important. Real-time transmission of industrial site temperature through Gigabit Ethernet can realize high-speed an...
