Embodiment 1

[0033] Such as image 3 As shown, a plug-and-play sensor monitoring system includes two parts: an acquisition unit and a monitoring unit IED. The acquisition unit includes an acquisition interface, an analog-to-digital conversion module, a first memory, a first CPU, an electronic data table TEDS, and the first interface module DANH of the HSR optical fiber ring network, and the monitoring unit IED includes a second interface module DANH of the HSR optical fiber ring network, a network matching A processing module NCAP, a second memory and a second CPU.

[0034] Flowchart of information interaction between acquisition unit and monitoring unit IED Figure 4 As shown, after the acquisition unit is installed, powered on and connected to the sensor, it needs to be instantiated. The instantiation is mainly to set the self-describing information of the sensor such as node position and access volume, and import the electronic data form TEDS Middle; the acquisition unit sends the sen...

Abstract

The invention relates to the field of high-voltage equipment state monitoring, and specially relates to a monitoring method and system, and an acquisition unit for a plug and play sensor. Self-description information of the sensor is sent to a monitoring unit through the acquisition unit, and the monitoring unit receives and stores the self-description information of the sensor to achieve plug-and-play of the sensor, and so, large configuration workload, low efficiency, and error-prone problems are solved; through configuration of the self-description information of the sensor in an electronicdata table, the scalability of the system is improved, and the condition of manual intervention is reduced when a power system online monitors that the sensor accesses to a state monitoring system; and the compatibility and the real-time performance of the monitoring system are improved through adoption of a communication mode of an HSR optical fiber ring network.

Description

technical field [0001] The invention relates to the field of state monitoring of high-voltage equipment, in particular to a plug-and-play sensor monitoring method, a system thereof, and an acquisition unit. Background technique [0002] With the rapid promotion of smart substations / digital substations, condition monitoring technology has been widely used in power systems, which has greatly promoted the safe operation of power systems and accumulated rich experience. At the same time, many problems were exposed: [0003] 1. There are many types of sensors, and there are inconsistencies in access signals, data interfaces, and communication protocols. At the same time, the strong electromagnetic field interference near the primary equipment leads to a high failure rate of sensors and complicated replacement and maintenance. [0004] 2. Due to the high real-time requirements for data interaction between different sensors, especially for lightning arresters, capacitive equipment...
