Problems solved by technology

VNC is a technology similar to remote desktop, which realizes that the content displayed on the screen on the local HMI is consistent with that displayed on the remote PC or smart terminal. However, VNC requires sufficient network bandwidth and stable data connection. In environments such as mobile networks In this situation, the connection is often slow, interrupted or unable to connect, which greatly affects the experience of remote operation

Embodiment 1

[0024] This embodiment is used to describe the shortcomings of the prior art and the solution ideas of this statement.

[0025] The existing VNC method (VNC (Virtual Network Console) is the abbreviation of Virtual Network Console) and a remote PC or mobile terminal running a configuration method similar to the local HMI, there are such as mentioned in the background technology In order to improve the operating stability of the system, it is necessary to achieve data synchronization between the HMI and the remote controller (ie terminal device). To this end, this embodiment provides figure 1 The HMI configuration synchronization system shown includes HMI (Human-Machine Interface) 1 and local equipment 2, including a number of terminal equipment 3 and relay server 4 running remote configuration. Correspondingly, this embodiment also provides Such as figure 2 The HMI configuration synchronization method shown in 1:

[0026] S1. Any terminal device changes the parameter of the remote ...

Embodiment 2

[0030] The purpose of this embodiment is to explain the preferred solution:

[0031] In step S1, "change of any terminal device" specifically includes that at the same time, only one terminal device and HMI are transmitting parameters (that is, in the case of direct connection). For example, when two terminal devices are in contact with HMI at the same time and prepare For data transmission, at this time, HMI will only select one of the terminal devices to receive parameters and make local configuration changes, or at the same time there are two or more terminal devices connected to the HMI through the relay server, and the relay server only One parameter will be transmitted to the HMI at a time. The basic principle can be to transfer the parameters in chronological order, or the HMI can receive both parameters at the same time, but only one of the parameters will be used for local configuration changes. After the local configuration change is completed, the HMI will change the c...

Embodiment 3

[0035] This embodiment is used to provide image 3 An HMI configuration synchronization mechanism, involving HMI (with local configuration program), data forwarding server (ie relay server), terminal equipment (such as mobile phone, PC, with remote configuration program), the corresponding process includes steps :

[0036] S01. The remote configuration data of (any) terminal device (marked as A in this embodiment) changes, and the corresponding value is written into the local configuration;

[0037] S02. After the local configuration of HMI is changed, the data forwarding server is notified (by means of the update event) to indicate that the data has changed, and the changed value (subject to the update event) is saved on the server (ie, the relay server) );

[0038] S03. The terminal device (A) queries the data change in the server (that is, whether there is an update event);

[0039] S04. The server responds with a data change (At this time, A knows that the HMI has indeed changed ...

Abstract

The invention discloses an HMI configuration synchronization system and an HMI configuration synchronization method, and the system comprises an HMI which comprises a plurality of terminal devices running remote configuration and a relay server. The method comprises the steps that S1, any terminal device changes parameters of a remote configuration to which the terminal device belongs, and the parameters are directly transmitted to an HMI or transmitted to the HMI through a relay server; S2, corresponding parameter change is performed on the local configuration by the HMI, and uploading an updating event to the relay server when the parameter change is completed; and S3, the terminal equipment obtains the updating event from the relay server, and changes the parameters of the remote configuration to which the terminal equipment belongs according to the updating event. According to the invention, the remote configuration parameters are changed through the terminal equipment; the HMI correspondingly modifies the local configuration according to the parameters, when the HMI completes the modification, the updating event is generated and uploaded to indicate the details of the change of the parameters, and the terminal equipment changes the remote configuration according to the updating event, so that the synchronization of configuration data can be realized to improve the requirement of system consistency, and the system operation risk is reduced.

Description

Technical field [0001] The invention relates to the field of automation technology, in particular to an HMI configuration synchronization system and method. Background technique [0002] HMI is the abbreviation of Human Machine Interface, also called "Human Machine Interface". It is a medium for interaction and information exchange between the system and users. It realizes the conversion between the internal form of information and the form acceptable to humans. Human-machine interfaces exist in the field of information exchange. It is an important part of industrial automation and industrial information. HMI runs with configuration to realize various functions, and configuration software can realize the monitoring and control of automation process and equipment. [0003] In the current system, most of the human interface is installed with the machine equipment, making it easy for users to control the machine on site. With the development of the Internet of Things and smart mobi...
