Problems solved by technology

[0002] In the fields of nuclear power and industrial control, a distributed control system (DCS) often has hundreds or even thousands of circuit boards, and each circuit board has one or more processors (FPGA, CPU) due to different production batches, Or the board card is damaged and replaced, which may lead to inconsistency in the program version of the processor. Due to the large number, it is difficult to troubleshoot. It is urgent to develop an FPGA-based online automatic update protocol method to solve the above problems.

Embodiment Construction

[0039] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0040] An FPGA-based online automatic update protocol method, a DCS distributed control system includes multiple circuit boards, the controller in the control station is used as the master node for communication, and other boards are used as slave nodes for communication; after the slave nodes are powered on Initialize to obtain version information first, wait for the controller to read its status and version information, and start after receiving the start command from the controller;

[0041] Specifically include the following steps:

[0042] (1) Program storage of each board processor of the control station

[0043] When the engineer station compiles the engineering configuration, it compiles the configuration information of all boards of the DCS control station together and downloads them to the controller;

[0044] Boards include controll...

Abstract

The invention belongs to the technical field of industrial control systems, and particularly relates to an online automatic protocol updating method based on an FPGA. One DCS distributed control system comprises a plurality of circuit boards, a controller in a control station is used as a master node for communication, and other board cards are used as slave nodes for communication; and the slavenodes are firstly initialized to obtain version information after being powered on, wait for the controller to read the state and version information of the slave nodes, and can be started only afterreceiving a starting command of the controller. According to the technical scheme, the consistency of board card program versions can be guaranteed through the DCS, and manual intervention is not needed; and when the board cards are subjected to hot replacement, the versions of the board cards can be confirmed, and when the versions are inconsistent, automatic updating is achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial-grade control systems, and in particular relates to an FPGA-based online automatic update protocol method. Background technique [0002] In the fields of nuclear power and industrial control, a distributed control system (DCS) often has hundreds or even thousands of circuit boards, and each circuit board has one or more processors (FPGA, CPU) due to different production batches, Or if the board is damaged or replaced, it may cause inconsistency in the program version of the processor. Due to the large number of problems, it is difficult to troubleshoot. It is urgent to develop an FPGA-based online automatic update protocol method to solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an FPGA-based online automatic update protocol method, so that the program version of the processor (CPU, FPGA) in the distribute...
