Problems solved by technology

[0005] 1. Due to the uncertain configuration of the actual project, if all board faults are artificially cascaded, due to the large number of boards, the wiring work is more complicated
[0006] 2. Due to the uncertain configuration of the actual project, if all board faults are judged by software according to the configuration, it will increase the complexity of the system fault alarm design

Embodiment Construction

[0022] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0023] Below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail:

[0024] as attached figure 1 As shown, the board-level fault unit receives the fault signal of the board and sends it to the chassis-level fault unit in summary, and the chassis-level fault unit sends the received fault signal to the cabinet-level fault unit in summary, and the cabinet-level fault unit The received fault signals are collectively sent to the fault output unit, and the fault output unit outputs a fault warning signal.

[0025] as attached figure 2 As shown, the chassis is composed of two boards, one is a function board, w...

Abstract

The invention provides a multi-board system fault reporting method. A pure hardware fault reporting mode is adopted, fault alarming is conducted by setting board-level faults, case-level faults and cabinet-level faults in a level-by-level reporting mode, and the technical aim of easily and rapidly positioning fault areas is achieved. According to the multi-board system fault reporting method, board faults are collected through a fault summary module and are output to give an alarm through a relay fault output module, fault signals are transmitted through relays and connection wires in the whole fault alarming process, the complexity of the product design caused by usage of software alarming is avoided, and meanwhile the complexity of the project design is also lowered.

Description

technical field [0001] The invention relates to the technical field of DCS equipment in the industrial control industry, in particular to a system fault reporting method. Background technique [0002] The faults of the existing cabinet chassis structure system are all reported by the network. Taking the DCS control system as an example, two types of boards are installed in the chassis: smart boards and non-smart boards. [0003] For smart boards, there are generally main processing unit boards, communication boards, and IO boards. The main processing unit obtains the data of the IO boards and communication boards through the network, and can also obtain fault information for calculation and processing, but the design complexity is relatively high. high. [0004] The DCS system is usually a cabinet-type structure. The system is characterized by an industrial control cabinet. A 19-inch or other size cabinet is placed in the cabinet. Functional boards can be placed in the cabi...
