Embodiment 1

[0028]Preferred Embodiment 1: The controller 5 of the industrial production equipment 6 is a programmable logic controller (PLC). The wireless communication module 2 configured for the PLC is a Bluetooth communication module. The 8 contacts in the PLC digital input are used to control the 3 quantities of hardware switches, one contact is used to control the PLC to work in the wireless communication mode of the shielded Bluetooth module, and one contact is used to allow Bluetooth communication but only for sending device information to In the mode of external output, one contact sets the external intelligent terminal 1 HMI as the master device and the local HMI as the slave device mode. Before the execution of the external program, it is required to manually close the contact once. This function occupies one contact, one The contact is used to restore the factory configuration, and the other contacts are reserved. In the software of the PLC controller, set the Bluetooth connec...

Embodiment 2

[0030] Preferred embodiment two: the controller 5 of industrial production equipment 6 is an industrial control computer (being referred to as industrial computer for short), runs the UNIX operating system, and provides a graphical interface, and the wireless communication module 2 that this industrial computer is equipped with is a bluetooth communication module . Establish digital input on the industrial computer side, which can correspond to the specific hardware switch 3 quantity setting state, so as to control the communication connection with the portable terminal man-machine interface. Here, the communication state is specially set as: allow Bluetooth communication, Bluetooth communication The information flow is only from the industrial computer to the smart terminal1. The external intelligent terminal 1 adopts a tablet computer with a bluetooth communication module, and installs application programs for operation control of multiple devices in it to receive external i...

Embodiment 3

[0032] Preferred embodiment three: the controller 5 of the industrial production equipment 6 is an industrial computer, and the intelligent terminal 1 is a smart phone with a networking function. When a device fails, the manufacturer of the device will be requested for factory repair. After a series of information confirmation links, the equipment manufacturer locks the smartphone, downloads a special diagnostic program to the smartphone that is not disclosed to the public, controls the equipment through the smartphone man-machine interface, and diagnoses the equipment failure. If it is determined that the equipment failure can be If the software is corrected, software upgrades can be carried out. If it is determined that a certain hardware component must be replaced due to equipment failure, the equipment manufacturer can prepare replacement parts accordingly. After a few days, the equipment manufacturer will send someone or the local equipment engineer of the factory , to re...

Abstract

The invention relates to a technology of adopting intelligent terminals as a human-computer interface of industrial equipment control. The technology comprises the intelligent terminals and industrial production instrument equipment, a plurality of controllers are arranged on the industrial production instrument equipment, communication control hardware and information flow recognition and control software are arranged on the controllers, and the communication control hardware on each controller is a relay. A many-to-many communication contact mode is built between the intelligent terminals and the controllers of the industrial production instrument equipment. The portable intelligent terminals are adopted as the novel human-computer interface, and used for assisting in running control over instruments and equipment, the intelligent terminals are easy to obtain in practice, and the instruments and the equipment can be flexibly and conveniently controlled. One intelligent terminal can control different equipment, the action of different permissions of the single equipment can be attached to the different intelligent terminals, and therefore the operation and control mode is converted into the many-to-many mode from the previous one-to-one mode.

Description

【Technical field】 [0001] The invention relates to the technical fields of high-end equipment and automation control, and in particular relates to a technology using an intelligent terminal as a man-machine interface controlled by industrial equipment. 【Background technique】 [0002] With the increasing popularity of computer technology and automation control technology, modern industrial manufacturing equipment, including many instruments with complex functions, has become intelligent, and there is also a trend of rapid development of production line employees in the direction of robots. As an automated manufacturing equipment or instrument, in addition to the operation of the whole machine under the control of intelligent modules such as programmable logic controller (PLC) or industrial computer, it is also necessary to provide a human-machine interface of the intelligent module for the actual operation of the equipment. Operators, or process engineers, and equipment engine...
