Two-dimensional code state display instrument of intelligent equipment of transformer substation

Abstract

A two-dimensional code state display instrument of intelligent equipment of a transformer substation comprises a power module, a single chip microcomputer, a liquid crystal display screen and a communication interface, and is characterized in that the power module is externally connected with an external alternating-current power source, the external alternating-current power source is converted into two channels by the power module, one channel of the external alternating-current power source is connected with the single chip microcomputer while the other channel is connected with the liquid crystal display screen, the single chip microcomputer is respectively connected with the liquid crystal display screen and the communication interface by two internal communication lines, and the communication interface is connected with a 485 interface of a communication interface of the intelligent equipment of the transformer substation by an external communication line. Messages transmitted from the intelligent equipment of the transformer substation are read by the two-dimensional state display instrument of the intelligent equipment of the transformer substation by means of decoding, the messages are processed according to a compiled program at first after being analyzed, then important information is recorded and stored as needed, simultaneously, the current running state of the equipment is evaluated, the liquid crystal display screen is driven to display processed data of the running state of the equipment in a two-dimensional code manner, and the information is read by maintenance personnel of the equipment via intelligent mobile phones, tablet computers and laptops with a photography function.

Description

technical field [0001] The invention relates to an electrical testing instrument, in particular to a two-dimensional code state display instrument for substation intelligent equipment. Background technique [0002] The existing substation intelligent secondary equipment can transmit information to the outside world through the display screen and network communication interface of the device itself. An important aspect of this information is the operating status of the equipment, including equipment exception messages, current equipment status, and equipment accident information. However, on the one hand, the display area of ​​the device itself is limited and it can display more text information. If you want to see all the information, you need to perform multiple operations on the device, and there is a possibility of misoperation during viewing; When viewing this information on the Internet, it is often impossible to collect and organize these data well due to reasons suc...

However, on the one hand, the display area of ​​the device itself is limited and it can display more text information. If you want to see all the information, you need to perform multiple operations on the device, and there is a possibility of misoperation during viewing; When viewing these information on the Internet, it is often impossible to collect and organize these data well due to reasons such as network communication, device interface mismatch, or large amount of data stored in the background machine.
