Embodiment 1

[0049] This embodiment provides an automatic tuning method for a line fault indicator. The tuning system proposed by the present invention communicates with the acquisition unit of the line fault indicator through a repeater, thereby reading telemetry data and issuing control instructions. The flow of the tuning method proposed by the present invention is as follows: figure 1 The specific implementation steps are as follows:

[0050] 1. Hang the acquisition unit of the line fault indicator to be set on the test rod, scan the QR code or barcode of the acquisition unit with a code scanner, and enter the equipment information of the acquisition unit and test related parameters into the tuning system, such as the communication frequency band number, mailing address, etc. In order to improve the test efficiency, it is best to ensure that the communication frequency band numbers of the tuning samples of the same batch are consistent.

[0051] 2. The tuning system sets the frequenc...

Embodiment 2

[0066] This embodiment provides an automatic tuning system for a line fault indicator, such as figure 2 As shown, it includes an acquisition unit information input module, a repeater frequency band address setting module, a power acquisition test module, a setting test module, a current accuracy test module, a wave recording test module, a test result judgment module and a command broadcast module.

[0067] Acquisition unit information input module: scan the QR code or barcode of the acquisition unit of the line fault indicator to be set with a code scanner, read and enter the equipment information of the acquisition unit and test related parameters.

[0068] Repeater frequency band address setting module: According to the set parameters, set the frequency band number and address of the repeater; after the setting is completed, check whether the communication between the repeater and the current batch of line fault indicator acquisition units is successful; if the communicatio...

Abstract

The invention discloses an automatic setting method and system for a line fault indicator. The tuning method of the present invention includes: entering into the tuning system the equipment information of the acquisition unit of the line fault indicator to be tuned and test-related parameters; the tuning system sets the frequency band number and address of the repeater according to the set parameters; after the setting is completed, the tuning system Detect whether the communication between the transponder and the current batch of line fault indicator acquisition units is successful; the line fault indicator with unsuccessful communication is marked, and does not participate in the subsequent steps; the tuning system performs a power-taking test to detect the line fault indicator. Whether the acquisition unit can take power normally; carry out the setting test of the acquisition unit; test the current accuracy of the acquisition unit; test the wave recording function and wave recording performance of the acquisition unit. The invention can ensure the setting accuracy of the line fault indicator, realize test automation and improve test efficiency.

Description

technical field [0001] The invention relates to the field of setting of power supply system equipment, in particular to an automatic setting method and system of a line fault indicator. Background technique [0002] In the intelligent distribution network, the use of the line fault indicator can improve the stability of the power supply system, locate the fault point and reduce the adverse impact of the distribution network system failure on the system operation. In order to ensure that the line fault indicator can accurately monitor the line status in the intelligent distribution network, and correctly identify the short circuit and ground fault, the line fault indicator should be strictly tested before leaving the factory. [0003] The current line fault indicator tuning methods generally have the following deficiencies: insufficient tuning and testing items, over-reliance on labor, cumbersome operation, low setting efficiency, and cannot fully meet the needs of mass produ...
