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] Existing VNC mode (VNC (Virtual Network Console) is the abbreviation of virtual network console) and on remote PC or mobile terminal, run a mode of the same configuration as local HMI, exist as background technology mentions problem, and in order to improve the operation stability of the system, it is necessary to realize the data synchronization between the HMI and the remote controller (that is, the terminal device). For this reason, this embodiment provides the following figure 1 A kind of HMI configuration synchronous system shown, comprises HMI (Human-Machine Interaction Interface) 1 and local device 2, comprises a plurality of operation terminal devices 3 and relay server 4 with remote configuration, correspondingly, this embodiment also provides like figure 2 HMI configuration synchronization method 1 shown:

[0026] S1. Any terminal device ...

Embodiment 2

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

[0031] In step S1, "changing any terminal device" specifically includes that at the same time, only one terminal device and the HMI perform parameter transfer (that is, the case of direct connection). For example, when two terminal devices contact the HMI at the same time and prepare to For data transmission, at this time, HMI will only select one of the terminal devices to receive parameters and perform local configuration changes, or at the same time, there are more than two terminal devices connected to HMI through the relay server, and the relay server only It will transmit one parameter to the HMI at a time. The basic principle can be to transmit 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 configur...

Embodiment 3

[0035] This example is used to provide image 3 A 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 equipment (marked as A in this embodiment) changes, and the corresponding value is written into the local configuration;

[0037] S02. After the local configuration of the HMI has been changed, (via the update event) notify the data forwarding server to indicate that the data has changed, and save the changed value (the content of the update event) in 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 that there is a data change (at this time A knows that the HMI has i...

Abstract

The invention discloses an HMI configuration synchronization system and method. The system includes an HMI, a plurality of terminal devices and a relay server running remote configuration. The method includes: S1. Any terminal device changes the parameters of the remote configuration to which it belongs, and transmits the parameters to the HMI directly or through a relay server; S2. The HMI changes the corresponding parameters for the local configuration, and uploads the parameter when the parameter change is completed. Update the event to the relay server; S3. The terminal device obtains the update event from the relay server, and changes the parameters of the remote configuration to which it belongs according to the update event. The present invention changes the parameters of the remote configuration through the terminal equipment, and the HMI modifies the local configuration according to the parameters. When the modification is completed, the HMI generates and uploads an update event to illustrate the details of the parameter change, and the terminal equipment changes the remote configuration according to the update event. , can realize the synchronization of configuration data to improve the requirements of system consistency and reduce the risk of system operation.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to an HMI configuration synchronization system and method. Background technique [0002] HMI is the abbreviation of Human Machine Interface, also known as "Human-Machine Interface". It is a medium for interaction and information exchange between the system and users. Human-machine interface exists in the field of information exchange. It is an important part of industrial automation and industrial informatization. Configuration is run in HMI to realize various functions, and configuration software can realize monitoring and control of automation process and equipment. [0003] In the current system, most of the human interface is installed together with the machine equipment, which makes it very convenient for the user to control the machine on site. With the development of the Internet of Things and smart mobile devices, people have an increasing demand for remote information...
