Portable plant station terminal data acquisition device

Abstract

The invention discloses a portable plant-station terminal data acquisition device which can program configuration files for data capture, compile data capture requirements into program scripts in advance, directly access a plant-station terminal database through a USB interface of a USB controller, automatically identify configuration information of a plant-station terminal, and automatically acquire the configuration information of the plant-station terminal according to script file requirements pre-edited by a user. The portable plant-station terminal data acquisition device captures data from a plant-station terminal, converts the data into a format recognized by a master station system, generates a data file in a preset format, responds to a control instruction of the master station system through a master station system USB interface after completing the data capture of the plant-station terminal, and transmits the captured data to the master station system. The technical problem that the integrity of data of a master station is affected due to the fact that data collected by an existing substation metering plant station terminal cannot be recovered and uploaded in time when communication between the plant station terminal and the master station is interrupted due to network channel faults or equipment faults is solved.

Description

technical field [0001] The invention relates to the technical field of power grid meter reading, in particular to a portable plant terminal data acquisition device. Background technique [0002] The electric energy meters of the substation are installed in various scattered high-voltage rooms or main control rooms. The data of the electric energy meters are collected to the electric energy meter collection terminal through various communication methods, and the electric energy meter collection terminal collects and stores the data of the electric energy meter, and then uploads them to all levels of metering Automation master system. [0003] At present, the upstream communication of substation metering station terminals generally adopts the dispatching data network or GPRS communication method. Although the network channel has basically met the requirements, emergency measures and plans have not been considered at present. Once the network channel fails or equipment failure ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a portable station terminal data acquisition device, which is used to solve the problem of data collection by the station terminal when the network channel of the existing substation metering station terminal fails or the equipment fails to cause the communication between the station terminal and the main station to be interrupted. The data cannot be restored and uploaded in time, which affects the technical problems of the data integrity of the master station
