Description

HMI configuration synchronization system and method

Technical Field

The invention relates to the technical field of automation, in particular to an HMI configuration synchronization system and an HMI configuration synchronization method.

Background

The HMI is an abbreviation of Human Machine Interface, also called a Human-Machine Interface, is a medium for interaction and information exchange between a system and a user, realizes the conversion between an internal form of information and a Human acceptable form, and has a Human-Machine Interface in the field of Human-Machine information exchange. Is an important component of industrial automation and industrial informatization. The HMI is configured to perform various functions, and configuration software enables monitoring and control of automated processes and equipment.

In the current system, most human interfaces are installed with machine equipment, so that a user can conveniently control the machine on site. With the development of the internet of things and intelligent mobile devices, people have stronger and stronger requirements for information interaction between remote implementation and machines, but most of the current schemes mainly adopt a VNC mode to realize remote and local synchronous display. The VNC is a technology similar to a remote desktop, and realizes that the content displayed on a screen on a local HMI is consistent with the content displayed on a remote PC or an intelligent terminal, but the VNC needs enough network bandwidth and stable data connection, and under the environment of a mobile network and the like, the situations of slow connection, interruption or no connection often occur, so that the experience of remote operation is greatly influenced. Another solution is to run a configuration similar to the local HMI on the remote PC or mobile terminal, but the data synchronization between the two configurations (local: run on HMI and remote: run on PC or mobile) becomes a more important issue, and in addition, when there are multiple remote devices accessing a local device at the same time, the data consistency in the 1-to-N relationship becomes more important.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Example 1

This embodiment is provided to describe the disadvantages of the prior art and the solution of the present statement.

The existing VNC (virtual Network controller) mode (abbreviated as virtual Network console) and the mode of operating a configuration same as that of a local HMI on a remote PC or mobile terminal have the problems mentioned in the background art, and in order to improve the operation stability of the system, it is necessary to implement data synchronization between the HMI and a remote controller (i.e. a terminal device), for this reason, this embodiment provides an HMI configuration synchronization system shown in fig. 1, which includes an HMI (human-machine interface) 1 and alocal device 2, which includes a plurality ofterminal devices 3 and arelay server 4 operating with remote configurations, and correspondingly, an HMIconfiguration synchronization method 1 shown in fig. 2 is also provided:

s1, any terminal equipment changes the parameters of the remote configuration to which the terminal equipment belongs, and the parameters are directly transmitted to the HMI or transmitted to the HMI through a relay server;

s2, the HMI carries out corresponding parameter change aiming at the local configuration, and when the parameter change is completed, the HMI uploads an update event to the relay server;

and S3, the terminal equipment acquires the update event from the relay server and changes the parameters of the remote configuration to which the terminal equipment belongs according to the update event.

Example 2

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

in step S1, "any terminal device change" specifically includes that, at the same time, only one terminal device and HMI perform parameter transmission (i.e. the case of direct connection), for example, when two terminal devices simultaneously contact the HMI and prepare to perform data transmission, at this time, the HMI only selects one of the terminal devices to perform parameter reception and perform local configuration change, or when at the same time, more than two terminal devices connect the HMI through a relay server, and the relay server only transmits one parameter to the HMI at a time, the basic principle may be that the HMI receives both parameters at the same time, but only one of the parameters is used to perform local configuration change, and when one local configuration change is completed, the HMI performs configuration change according to another parameter, and the more parameters are based on the processing procedure as a blue book, namely that described in the preferred embodiment of S2; the update event is a data stream, and is intended to explain information such as details (for example, what parameters are changed), procedures (parameter change order, etc.), time, etc. of local configuration update; in step S3, three modes may be included, that is, the relay server issues the update event in real time and/or the terminal device accesses the relay server in real time to obtain the update event, where inmode 1, the benefit of the real-time issue of the relay server is the real-time performance of the update event, and meanwhile, the consumption of the real-time access mode of the terminal device may be reduced; in themode 2, the real-time access mode of the terminal equipment has the advantages that the state of the terminal equipment can be proved, and because the terminal equipment is abnormal or abnormal in a network when the terminal equipment does not access the relay server in real time any more, the state of each part of the whole system can be detected in real time, which cannot be realized by the real-time release mode of the relay server; of course, the above two modes (i.e., the third mode) may be performed simultaneously without reducing the system consumption.

Step S0 may also be included: the HMI acquires and executes step S2 according to the local operation, in this case, as in the HMIconfiguration synchronization method 2 shown in fig. 3, the HMI may change the local configuration by the local operation, and then continues to execute steps S2 and S3 to achieve synchronization. Meanwhile, due to the local operation (two local configuration changes cannot be generated by one local operation), the problem that terminal equipment is disordered due to multiple changes at the same time is avoided.

The local configuration and the remote configuration may be the same, because some terminal devices (e.g. mobile phones) do not need to perform the complete function of the local device, only a part of the remote configuration is needed to control the local device, and certainly, if the terminal device (PC) is excellent in self-function, the local device can be completely controlled, or the remote configuration and the local configuration are the same; the corresponding technical advantage lies in the ability to meet the control requirements of terminal devices of different capabilities.

Example 3

The present embodiment is configured to provide an HMI configuration synchronization mechanism as shown in fig. 3, and relates to an HMI (provided with a local configuration program), a data forwarding server (i.e. a relay server), and a terminal device (e.g. a mobile phone, a PC, provided with a remote configuration program), where the corresponding process includes the steps of:

s01, the remote configuration data of the terminal (any terminal) is changed, and the corresponding value is written into the local configuration;

s02, after the HMI local configuration is modified, notifying the data forwarding server (by the update event) to indicate that the data has changed, and storing the changed value (the content belonging to the update event) in the server (i.e., the relay server);

s03, the terminal device (A) inquires about data change in the server (namely whether an update event exists);

s04, the server responds to the data change (at the moment, A knows that the HMI does not change the local configuration according to the requirement);

s05, other terminal equipment inquires about data change in the server (namely whether an update event exists);

s06, the server responds that there is data change, and other terminal devices synchronize according to the responded information.

The present embodiment is mainly aimed at the feedback of the terminal device (a), because the user operating the terminal device (a) needs to know whether the change is completed correctly (may be to generate a prompt message for completing the change, and the user knows that the change is completed when seeing the prompt message); in theory, in step S3, the terminal device (a) does not need to perform synchronization, but still performs data synchronization once to prevent accidents, and at this time, the user will know that the change is completed according to the data synchronization, but it is still convenient to determine according to the feedback (because the synchronization itself is only the change of the parameter, and if the comparison is performed according to the parameters to confirm the completion of the change, it is too time consuming, and it is not convenient as a prompt message, and the prompt message may be simple text, voice, etc.).

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
