Method and device implementing on-line upgrading of a fixed programme

Abstract

The invention discloses a method for realizing on-line upgrade of a solidified program. At least a first backup area and a second backup area are set respectively, and at least one of the backup areas contains an executable application program, including: A. The control system receives the upgrade and solidifies A program command; B. update the second backup area with the received new firmware program; C. update the first backup area with the new firmware program in the second backup area. The invention also discloses a device for realizing on-line upgrading of the solidification program. The application of the present invention can realize the real-time online upgrade of the solidification program during the working process of the control system, which improves the reliability of the online upgrade of the solidification program; since the online upgrade process can simultaneously perform control operations, it overcomes the limitations of the online upgrade and the realization of the control function. The disadvantage of choosing one or the other improves the integrity of the entire control system operation.

Description

technical field [0001] The invention relates to the field of industrial automation control, in particular to a method and a device for realizing online upgrading of a solidification program. Background technique [0002] In the field of industrial control, especially in the process of updating the solidification program of the control system, it is required that the update process cannot affect the on-site production process, so as to ensure the continuous, stable and reliable operation of the control system. The update method of the firmware program in the prior art separates the firmware program supporting online upgrade from the system function firmware program in the system. The flow of the update method is as follows: figure 1 Shown: [0003] Step 101: After the system is powered on and started, a firmware program supporting online upgrade is executed. [0004] Step 102: The firmware program supporting online upgrade initializes the hardware in the system. [0005] S...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to provide a method for realizing the online upgrade of the solidified program, so as to overcome the problem that the reliability of the upgrade method in the prior art is not high, and the online upgrade and the realization of the control function can only be carried out one by one.

[0012] Another object of the present invention is to provide a device for realizing the online upgrade of the solidified program, so as to overcome the problem in the prior art that the reliability of the upgrade is not high, and the online upgrade and the realization of the control function can only be carried out in one way.
