Embodiment Construction

[0037] The industrial control system applied in the present invention includes a microprocessor and multiple memories, one of which is designated as the main program memory, and the rest are used as backup program memories. The memories in this embodiment are the same and store The addresses are continuous, and can be used as a working program area for the industrial control system to implement control. Those skilled in the art know that the program memory is generally a non-volatile memory such as FLASH.

[0038] In the above industrial control system, the online download and update of the control program must stop the currently running control program, refer to figure 1 , in order to realize the continuity and reliability of the control program operation, the online upgrading method of the software of the present invention includes the following processes:

[0039] In step 11, the microprocessor controls a backup program memory to store downloaded software upgrade data and u...

Abstract

The invention relates to an on-line software upgrading method and device, applied to industrial control systems, and the method includes the following steps: an upgrading step: a microprocessor controls a backup program memory to store the downloaded software upgrading data and upgrades the corresponding software in the memory; a switching steps: the microprocessor controls to exchange the memory addresses of the upgraded backup program memory and the main program memory so as to switch the main and backup working program regions. The device includes: at least two memories, an address converting circuit and a microprocessor. As the software is upgraded, it implements the switch between the main and backup working program regions by the address converting circuit, ensuring stability, safety, reliability and continuity on industrial control occasions.

Description

technical field [0001] The invention relates to a software upgrading method and device, in particular to an online software upgrading method and device in an industrial control (referred to as industrial control) system. Background technique [0002] The computer used in the industrial control system is usually called the industrial control computer (referred to as the industrial control computer). In the industrial control system, the industrial control computer must process a large number of external signals, and then output control signals according to the processing results. [0003] The control machine is generally composed of two parts: computer and process input and output (I / O) channels. The computer is composed of control software, host, input and output devices, external disk drives, tape drives and other hardware devices. A part of the process input / output channel is added outside the computer, which is used to send the detection data in the industrial production...
