Problems solved by technology

[0004] 1. Since the local protection device is installed near the primary equipment, when downloading the parameter file, technicians need to go to the protection device to operate all the CPU boards sequentially, which takes a long time and is easy to miss. The parameter file is correct performance and reliability cannot be guaranteed
[0005] 2. In order to ensure that the data in the CPU board will not be lost after power failure, all CPU boards are equipped with the same memory chip at present, and the cost is relatively high
[0006] 3. The protection device operates under harsh outdoor conditions for a long time, and is easily affected by lightning strikes, sunspots, etc., and abnormal parameter files occur.
The existing protection device cannot timely detect the inconsistency of the parameters between the CPU boards, which is prone to malfunction, refusal to operate, and even cause major equipment damage and casualties

Embodiment Construction

[0023] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0024] Such as figure 1 , a method for synchronizing parameters of an in-situ protection device, the in-situ protection device includes several CPU boards, the core of the method is to centrally store all parameter files in one of the CPU boards, and the other CPU boards are accessed remotely Obtain the parameter file, and verify the obtained parameter file.

[0025] The specific steps are:

[0026] (1) One of the CPU boards is used as the management board, and the other CPU boards are used as protection boards; the management board is equipped with non-volatile memory, and communicates with the remote terminal through an external interface; the protection boards are respectively connected to the management board by communication .

[0027] and figure 2 The solutions shown in the prior art are different. In this embodiment, the protection board has...

Abstract

The invention discloses a method for synchronizing parameters of an in-situ protection device. In the method, all parameter files are centrally stored in one of the CPU boards, and other CPU boards obtain parameter files through remote access, and the obtained parameter files are processed. check. The present invention can only store parameter files on the management board, so that the downloading of the parameter files is simpler and more convenient, and at the same time saves the flash storage chip of the protection board, thereby reducing the device cost. The management board regularly verifies the parameter files of the protection board, which ensures the consistency of the parameter files and greatly improves the system stability and reliability.

Description

technical field [0001] The invention relates to a method for synchronizing device parameters of in-situ protection. Background technique [0002] The in-situ protection device is installed near the protected equipment, which aims to reduce the intermediate links of cable connection and data transmission, and improve the real-time and reliability of in-situ protection. [0003] An in-situ protection device usually consists of multiple CPU boards, and each CPU board uses its own parameter file. At present, the application of in-situ protective devices has the following problems: [0004] 1. Since the local protection device is installed near the primary equipment, when downloading the parameter file, technicians need to go to the protection device to operate all the CPU boards sequentially, which takes a long time and is easy to miss. The parameter file is correct performance and reliability cannot be guaranteed. [0005] 2. In order to ensure that the data in the CPU board...
