Multifunctional touch-screen industry tablet computer provided with emergency stop control switch

Abstract

Disclosed is a multifunctional touch-screen industry tablet computer provided with an emergency stop control switch. An industrial-control motherboard, a TFTLCD (thin film transistor liquid crystal display), a DC (direct-current) power source, a memory, an electronic hard disk, the emergency stop control switch, a qualified product control switch, an unqualified product control switch, a touch screen controller, a touch screen, an induction control keyboard board and an output amplifier circuit are all integrated in the multifunctional touch-screen industry. A CPU (central processing unit) and various interfaces are integrated in the industrial-control motherboard; an induction control keyboard array is controlled through a digital input port which can simultaneously receive station induction sensing signals of a production line member; a station control relay of the production line member is directly driven through the digital output port via the output amplifier circuit. By the application of an open-type system, a flexible component structure and the standard peripheral interfaces, the multifunctional touch-screen industry tablet computer is enabled to adapt to docking with an existing system of an enterprise. Standard products are adopted in main components, so that product quality is reliable, system upgrade is facilitated, and convenience and easiness in component maintenance are achieved.

Description

technical field [0001] The invention relates to a multi-functional touch industrial tablet computer, which is an industrial computer integrated with induction buttons, control buttons, touch screen and input and output control, and is an important equipment in the current manufacturing information engineering; it can be used as an electronic billboard, industrial Professional equipment such as control machines are widely used in manufacturing information engineering. Background technique [0002] In the process of management informatization, more and more enterprises realize that the key factor to win the competition is "execution". MES (manufacturing execution system, manufacturing execution system) began to receive widespread attention. In the national "Eleventh Five-Year" plan, it is also clearly proposed to "transform the manufacturing industry with informatization, promote the digitization of production equipment, intelligent production process and enterprise managemen...

AI Technical Summary

Problems solved by technology

[0004] The existing industrial control computer mainly consists of two schemes, one is the scheme of the host computer plus display and other peripherals, and the other is the scheme of the tablet computer plus other peripherals, because the use environment of the industrial control computer is relatively complicated, and most of them need Input information and automatic control functions; the current input scheme is mainly keyboard or touch screen input, and automatic control needs special equipment such as PLC to complete

Industrial control computers generally need to use few buttons in each position, and the input information is not very complicated. General keyboard equipment input is not very convenient to use, and in complex industrial environments, waterproof, anti-collision, anti-oil and other performance Poor, high failure rate; At present, all kinds of touch screen technologies have certain defects in long-term use in industrial environments, especially in the machining industry, due to oil pollution and metal powder will have a greater impact on the touch screen, if only alone Tablet PCs with touch screens often affect the operation of the system due to problems with the touch screen

At the same time, the automatic control of the production line needs to be realized by a separate PLC, which cannot be seamlessly integrated with the industrial manufacturing execution system (MES). This increases investment on the one hand, and reduces the degree of automation of the entire system on the other hand.
