Embodiment Construction

[0076] The core of the present invention is to provide a method for realizing the online upgrade of the solidified program. The method at least sets a first backup area and a second backup area respectively. At least one of the backup areas contains an executable application program. When the control system receives the upgraded solidified program After the command, update the second backup area with the received new firmware program, and then update the first backup area with the new firmware program in the second backup area.

[0077] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0078] The invention realizes the online upgrade of the solidified program while the...

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...
