Monitoring method and device for static information based on CRC (Cyclic Redundancy Check) inspection

Abstract

The invention discloses a monitoring method and a monitoring device for static information based on CRC (Cyclic Redundancy Check) inspection. The method comprises the steps of obtaining all static information of a relay protection device in a substation, and storing the static information to be binary data; taking the static information stored as the an information code for CRC checking, and calculating a corresponding CRC checking code through a CRC checking information algorithm; comparing the CRC checking code calculated with a preset checking code; transmitting an alarm signal to a centralized control center in a power grid according to a comparison result, if the CRC checking code is different from the preset checking code. In addition, the invention further discloses a static information monitoring device based on the CRC checking. According to the monitoring method provided by the invention, the workload of the operation and maintenance of equipment can be reduced reliably, the operation and maintenance efficiency can be improved, the checking accuracy of the information can be improved, and the powerful guarantee can be provided to the safe and stable operation of the power grid.

Description

technical field [0001] The invention relates to the technical field of grid equipment operation and maintenance, in particular to a static information monitoring method based on CRC check and a static information monitoring device based on CRC check. Background technique [0002] At present, the construction of smart grid has entered a stage of rapid development. Communication, computer, control and other modern information technologies are more and more closely integrated with traditional power technologies, and digital substations with a high degree of intelligence have begun to be put into operation. With the improvement of the comprehensive automation level of substations, the unattended operation mode in the substations has been widely implemented, and gradually developed from 110kV low-voltage level stations to 500kV high-voltage level stations, forming a remote monitoring of all substations in the area with the regional centralized control center as the hub A "dot-by...

AI Technical Summary

Problems solved by technology

[0003] At present, for the static information of the equipment in the power grid, such as fixed value, switch-in status, alarm status, self-inspection status, etc., the method of item-by-item inspection, item-by-item check, and multi-person confirmation is still adopted. The checking process is cumbersome, which is not conducive to operation. Maintenance personnel can intuitively and quickly understand the operation status of the device

At the same time, the more items that are manually checked, the greater the possibility of human errors such as misreading and omission, which endanger safe production
