Example Embodiment

[0063] The present invention requires the cooperation of the engineer station and the embedded software installed in the embedded device to be implemented, where

[0064] Engineer station: complete the algorithm configuration of the software under test, and compile it into embedded software executable "application software", usually a *.bin file, which supports downloading the executable "application software" to the embedded device .

[0065] Embedded devices: Embedded devices need to support software interaction with PCs, PCs can support the reading and writing of application software data content, embedded devices need to have communication modules such as serial ports or network ports to realize data interaction and communication functions with PCs ; Support downloading the executable "application software" compiled by the engineer station, scheduling the execution of the "application software" downloaded from the engineer station to the embedded device, and communicating with ...

Abstract

The invention provides an application software online debugging method based on a DCS. An embedded type device capable of operating application software and a computer device connected with the embedded type device are included, the embedded type device further comprises a data communication module and an application software data area, and the embedded type device and the computer device achieve data interaction through the data communicated module. The application software data area comprises global variables corresponding to local variables of application software one by one, and the computer device achieves reading, writing and accessing of data content of the application software through the global variables. The effect that in the fields such as nuclear power with high safety requirements, the application software operating in the embedded type device without an operation system is debugged is achieved. Furthermore, the application software online debugging method based on the DCS supports debugging of coded application software and supports onsite online debugging of the embedded type device.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant embedded equipment, and in particular relates to a method for online debugging of application software based on a DCS system. Background technique [0002] In the industrial control DCS system, the main control station is generally composed of embedded equipment and embedded software running on the equipment. The embedded software is usually divided into two parts, one is the operating system and the other is the application software. The "operating system" is used to implement general functions such as boot, drive, and communication, and the application software implements the user's business logic. In the nuclear power DCS industry, due to safety standards, the general-purpose operating system cannot meet the nuclear power standard review and quality requirements. The operating system function needs to be independently developed by the DCS provider. Although this part implements simi...
