Problems solved by technology

However, how to realize the long-term stable and reliable data acquisition of the state of the all-fiber optic current transformer in the whole station is a difficult problem. In actual operation, it needs to be unattended, otherwise, during the data collection process, the failure of a single device may lead to interruption

Embodiment 1

[0035] An embodiment of the present invention provides a state acquisition system for an all-fiber-optic current transformer, including a data acquisition unit and a server;

[0036] The data acquisition unit includes an all-fiber-optic current transformer and a serial port server; the serial-port end of the all-fiber-optic current transformer is connected to one of the ports of the serial-port server;

[0037] The server is connected in communication with the data acquisition unit; the server sends a data request signal to the serial port server in the data acquisition unit, and the serial server sends a data request signal from a suitable all-fiber current transformer according to the received data request signal. After the required data is obtained, it is sent to the server to complete the state collection of the all-fiber-optic current transformer.

[0038] In a specific implementation manner of the embodiment of the present invention, the all-fiber current transformer is ...

Embodiment 2

[0057] When an all-fiber-optic current transformer fails, the process module responsible for the data collection of the all-fiber-optic current transformer is suspended, and the data of other all-fiber-optic current transformers responsible for the process module cannot be collected. At the same time, if after a period of time, the faulty all-fiber current transformer resumes operation again, but because the process module responsible for the all-fiber current transformer has stopped running, the data of the all-fiber current transformer will no longer be collection. This situation can only manually restart the entire data acquisition system. In order to avoid the occurrence of the aforementioned situation, ensure the long-term stable and reliable operation of the state acquisition system of the all-optical current transformer, and ensure that the state acquisition system can always maintain normal operation during the process of equipment failure and failure recovery, without...

Embodiment 3

[0063] Based on the same inventive concept as in Embodiment 1, the embodiment of the present invention provides a state acquisition method of an all-fiber-optic current transformer, comprising the following steps:

[0064]Utilize the server to send a data request signal to the serial port server in the data acquisition unit;

[0065] The serial port server obtains the required data from the appropriate all-fiber-optic current transformer according to the received data request signal and sends it to the server to complete the state acquisition of the all-fiber-optic current transformer.

[0066] Further, the server is provided with several process modules and process management modules; each process module sends a request message to the corresponding serial port server based on the set configuration information, and the serial port server is based on the request message. The IP address information obtains the required data from the appropriate all-fiber-optic current transforme...

Abstract

The invention discloses a state collection system and method for an all-fiber current transformer. The system comprises a data collection unit and a server, the data collection unit comprises an all-fiber current transformer and a serial server; the serial port of the all-fiber current transformer is one port of the serial server; the server is in communication connection with the data collectionunit; the server sends data request signals to the serial server in the data collection unit, the serial server obtains required data from the proper all-fiber current transformer according to the received data request signals and then sends the data to the server to complete the state collection of the all-fiber current transformer. The state collection system and method can achieve the collection of the running states of all the all-fiber current transformers of the whole station on a single server, and the whole state collection system has the unattended characteristics of self diagnosis, self monitoring, self starting and the like, so that corresponding economic benefits are certainly brought.

Description

technical field [0001] The invention belongs to the technical field of ultra-high voltage direct current transmission, and in particular relates to a state acquisition system and method of an all-fiber-optic current transformer. Background technique [0002] A large number of all-fiber-optic current transformers are installed in UHV converter stations in the prior art, because the electronic units of all-fiber-optic current transformers provide external access through RS232 interfaces. When it is necessary to realize the collection of electronic unit status data of all fiber optic current transformers in the whole station, the electronic units in each full fiber optic current transformer can only be connected one by one through the serial port, and then view and download the report file. The content of the downloaded status text report needs to be manually checked one by one, which not only wastes time, but also requires a lot of manpower, and the status data is not stored u...
