Embedded logic controller

Abstract

The invention discloses an embedded logic controller. The embedded logic controller comprises a main control board and a core board connected through a GPIO interface, wherein the main control board is connected with a sensor, a static memory, a dynamic memory, an SD card, input expansion boards and input expansion boards and provided with a communication interface. A battery is arranged in the main control board. The core board is an ARM processor. The input expansion board is a 16-point input expansion board provided with 16 on-off input channels for connecting with peripheral input equipment. The output expansion board is a 16-point output expansion board provided with 16 on-off output channels for connecting with peripheral output equipment. The sum of the number of the 16-point input expansion board and the 16-point output expansion board is less than or equal to 8. The embedded logic controller has beneficial effects that the embedded logic controller can support larger program capacity, larger data capacity, richer communication mode and higher processing speed through the reasonable architecture and rich hardware resources and can meet the intelligent control requirement of an expressway tunnel.

Description

technical field [0001] The invention relates to the technical field of controllers, in particular to an embedded logic controller. Background technique [0002] With the rapid development of highway construction in our country, the number of highway tunnels has also increased. Due to the closed environment, once an accident occurs in the tunnel, especially a fire, it often leads to serious casualties and property losses. Therefore, issues such as lighting, ventilation, electromechanical, and fire-fighting facilities in the tunnel operation process have attracted more and more attention from the government and all walks of life. [0003] Therefore, it is of great significance to explore the safety management measures of expressway tunnels and build a reliable, stable, advanced, economical and scalable intelligent control system for tunnel lighting, ventilation, electromechanical, and fire-fighting facilities to ensure the safe driving of vehicles. From the particularity of ...
