Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0042] A data transmission method for the quality simulation test of an online monitoring device, such as figure 1 shown, including steps:

[0043] S1: The state access controller generates a corresponding message according to the output data of the online monitoring device, and sends it to the outside;

[0044] S2: Receive the message sent by the access controller, and analyze the message;

[0045] S3: Determine whether the message conforms to the I2 protocol according to the analysis result, if yes, store the message, if not, return a protocol error message to the state access con...

Abstract

The invention relates to a data transmission method and device for on-line monitoring device quality simulation testing. The method includes the following steps that: S1, a status access controller generates corresponding messages according to output data of an on-line monitoring device, and sends out the messages; S2, the messages sent by the status access controller are received, and are analyzed; and S3, whether the messages accord with the I2 protocol is jugged according to analysis results, if the messages accord with the I2 protocol, the messages are stored, if the messages do not accord with the I2 protocol, protocol error information is returned to the status access controller. Compared with the prior art, and according to the method of the invention, protocol analysis is performed on the messages sent by the status access controller, and when the messages do not accord with the I2 protocol, the protocol error information is fed back to the status access controller timely, and therefore, pre-verification can be performed on messages entering a testing device, and a specially-assigned person is not needed to perform protocol accordance judgment, and therefore, labor force can be saved.

Description

technical field [0001] The invention relates to the field of quality testing of online monitoring devices, in particular to a data transmission method and device for quality simulation testing of online monitoring devices. Background technique [0002] In order to grasp the quality of online monitoring devices for power transmission and transformation equipment at home and abroad, and provide reference for the company's equipment selection work, China Electric Power Research Institute established a state monitoring technology laboratory for power transmission and transformation equipment in 2013, responsible for carrying out test testing and analysis of test results, etc. . The detection objects of the substation part are four types of monitoring devices for dissolved gas (multi-component) in transformer oil, capacitive equipment, metal oxide arrester and transformer core grounding current. The test items for performance testing mainly include basic error, repeatability, cr...
