Abstract

The invention relates to a plug and play sensor monitoring system and an acquisition unit. The acquisition unit comprises an FPGA processor and a memory. The FPGA processor is connected to the memory.The FPGA processor is also provided with an acquisition interface used for connecting a sensor and a communication interface used for communicating with a monitoring unit. The memory is used for storing the self-described information of the sensor connected to the acquisition interface. The communication interface is used for sending the self-described information of the sensor to the monitoringunit. In the invention, the acquisition unit stores the self-described information of the sensor and sends the self-described information to the monitoring unit. The monitoring unit receives and stores the self-described information of the sensor. According to the self-described information of the sensor, the sensor, the acquisition unit and the monitoring unit are matched with each other. The plug and play of the sensor is realized, the expansibility of the system is increased, and problems that a configuration work amount is large, efficiency is low and an error is easy to generate are solved.

Description

technical field [0001] The invention relates to a plug-and-play sensor monitoring system and an acquisition unit, belonging to the technical field of high-voltage equipment state monitoring. 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, accumulated rich experience, and exposed many problems at the same time: [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 and partial discharge...
