DTU automatic test device based on core processing unit and DTU automatic test method thereof

Abstract

The invention discloses a DTU automatic test device based on a core processing unit and a DTU automatic test method thereof. The DTU automatic test device comprises the core processing unit which respectively communicates with a triumph standard source, an input and output module and a DTU device to be tested. The triumph standard source and the input and output module respectively communicates with DTU device to be tested. The core processing unit is connected with the standard source, the DTU device to be tested and the input and output module, and testing of remote signaling, remote control and remote measurement of the DTU device to be tested can be realized through the automatic test logic of the core processing unit so that hardware circuit connection is simple, use is convenient and corresponding function testing can be realized in testing by only performing simple circuit connection, and thus the test accuracy is high and testing of various functions can be rapidly realized.

Description

technical field [0001] The invention relates to the field of power distribution engineering automation, in particular to a DTU automatic testing device and method based on a core processing unit. Background technique [0002] At this stage, the testing and inspection of each manufacturer is only for a single item, for example: only for calibration and testing of analog quantities, and only for remote signaling and remote control testing. DTU is a data transmission unit. The current technical problems of DTU during testing are: [0003] 1. The efficiency is low, and there are many types of work, resulting in low quality inspection and testing, resulting in a certain waste of resources. [0004] 2. The number of tooling increases with the increase of the types of boards, the universality of the tooling is not strong, and the design is not flexible. [0005] 3. Tooling takes up a lot of resources, and additional signal sources, multimeters and other tools are required for tes...

AI Technical Summary

Problems solved by technology

[0003] 1. Low efficiency and many types of work, resulting in low quality inspection and testing, resulting in a certain waste of resources

[0004] 2. The number of tooling increases according to the increase in the types of boards. The universality of the tooling is not strong and the design is not flexible.

[0005] 3. The tooling takes up a lot of resources. During the test, additional tools such as signal sources and multimeters are required.

[0006] 4. The efficiency of tooling is not high, mostly manual operation, the degree of automation is not enough, not even automation; the existing tooling

[0007] 5. Many communication lines need to be connected externally, which looks messy and takes up more resources
