Portable intrinsically safe control terminal

Abstract

The invention provides a portable intrinsically safe type control terminal. A whole control system assembly is packaged in a portable box body with a shell protection grade of IP56; an upper panel assembly and a lower panel assembly are fixed on a control terminal shell through respective fixing holes respectively; an LBOX-2550 low-power-consumption display device is fixedly mounted on an upper panel through a display screen pressing strip and a flat head screw; a trumpet, a lifting handle, an indication lamp, a connector assembly and an aviation plug are fixedly mounted at one side of a lower panel in sequence through flat head screws; a host module and a power supply module are fixedly mounted at the other side of the lower panel; the indication lamp has two colors, red represents charging and green represents running; a power supply with the voltage grade of 12V is further mounted on the lower panel; the connector assembly is clamped on the lower panel; the connector assembly comprises two switches, a USB (Universal Serial Bus) interface, an SC optical fiber interface, an audio interface and an Internet access. The portable intrinsically safe type control terminal provided by the invention is small in size and light in weight, and simple in principle and structure; the portability problem about a small-size mobile equipment control terminal under explosive atmosphere gas is solved.

Description

technical field [0001] The invention relates to a control terminal, in particular to a portable intrinsically safe control terminal. Background technique [0002] The control terminal mainly refers to the terminal controller that can control a set of equipment or several sets of equipment; usually the core control system is composed of a microprocessor or an industrial control computer, and it is composed of peripheral equipment with related extended functions; a simple control terminal, Such as the main controller of the TV, the manipulator of the toy car; complex control terminals, such as the control system of traffic lights, the ground control system of aerospace, etc.; [0003] The above-mentioned control terminals are mostly used for civilian use or equipment in conventional environments. When designing, meeting the functional requirements is the primary consideration. For the equipment working in the explosive gas environment, its control terminal must first meet the...
