Management system for self-service remote update of PLC program and HMI project

Abstract

The invention discloses a management system for self-service remote updating of a PLC program and an HMI project in the technical field of computers, and the system comprises a server and a client, and can realize that the client actively downloads a program and a project, and a client directly logs in through an account and downloads the program in a self-service manner without the participation of an engineer; therefore, the system is not limited by time and places, as long as an application system is loaded anytime and anywhere, an administrator can log in a server, create different directories, directory names and remark information under a corresponding account number and upload a PLC program and an HMI project at the same time, and after creation is completed, the client can visually select the application program under the corresponding directory to download by logging in the account number. And a reliable program downloading security mechanism ensures that the application program does not flow out to cause loss. The application program file encryption adopts encryption processing to ensure that the file cannot be opened, secondarily developed and independently used even if the file is acquired in time.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a management system for self-service remote updating of PLC programs and HMI projects. Background technique [0002] The existing application program includes PLC application program and HMI project. Currently, the update of the PLC application program of the bending machine is updated by the programming card. Every time the system program upgrade program needs to make a programming card for each agent and the HMI update project needs to use U disk update. [0003] This system upgrade mode has several problems, [0004] 1. The efficiency of making programming cards is low. First, the agent needs to set up the remote environment. After the equipment is online, the engineer must be notified to download and make the programming card remotely through the computer. If the production fails, the company needs to make the programming card and mail it out, which will waste time . [...

Problems solved by technology

[0007] The purpose of the present invention is to provide a management system for self-service remote update PLC program and HMI project, to solve the above-mentioned background technology that engineers must download and make programming cards remotely through computers, and upgrade with the system version, the number of HMI projects and programming cards Too many, version management is chaotic, and the application program is easy to lose, the traceability is poor, and the number of downloads by customers cannot be counted in real time and authority management. Once the programming card is sent out, it is difficult to recover the problem
