Embodiment 1

[0042] like image 3 As shown, digitally based on LORA transmission is self-propelled, including test host 1 and at least one distributed test unit 2, the merge unit 3, the intelligent terminal 4, the process layer switch 5, and the digitization. The distributed test unit 2 is connected to the test host 1, each of which is connected to a merge unit 3 or the intelligent terminal 4, and all the merged unit 3 and all the intelligent terminal 4 are compounded through the process layer switch 5 and the digit. Self-investment 6. In this embodiment, the merge unit 3 includes a busbar merge unit and a spacing unit.

[0043] Test Host 1 Configure the output protocol and output port of the distributed test unit 2; test host 1 sends a test model to each distributed test unit 2; distributed test unit 2 generate real-time sampling data according to the test model according to the configured The output protocol and the output port output to the merge unit 3 or the intelligent terminal 4; the mer...

Embodiment 2

[0050] Based on the first embodiment of the present invention, the second embodiment of the present invention also provides a method of using LORA transmission-based digitally processed distributed test devices, continued to see image 3 The method includes:

[0051] Step 1: Before the test start, the test host 1 configures the distributed test unit 2, configures the output protocol of the distributed test unit 2, and the output port, the output protocol as an electronic transformer output protocol.

[0052] Step 2: Test the host 1 built-in configuration software, build the self-investigation logic by configuring software, automatically generate script files, test host 1 read script files to generate test models of self-investment automatic testing. The key point of the present invention is that the entire control logic is used for the design of the configuration software, and the configuration software is set up on the existing intelligent substation on-site logic, which is self-i...

Each distributed test sub-machine is connected with a merging unit or an intelligent terminal, and all the merging units and all the intelligent terminals are connected with the digital spare power automatic switching device; the device has the advantages that the system-level test of the digital spare power automatic switching device and the process level equipment thereof is realized, the matching between the digital spare power automatic switching device and the process level equipment is verified, the closed-loop control test between the digital spare power automatic switching device and the intelligent terminal as well as between the intelligent terminal and the test host is completed, the test model is updated in real time, and the safe operation of the intelligent substation is ensured.

Description

Technical field [0001] The present invention relates to the field of intelligent substations digitally processed self-investment system stage testing technology, and more particularly to LORA transmission-based digitally processed distributed testing devices and methods. Background technique [0002] In the smart substation, with the large-area application of digital sampling techniques such as electronic transformers and intelligent terminals, the test technology of digital samples cannot be limited to a single device's monomer test, which must be carried out based on process layer sampling. Level test. [0003] The function of digital preparation is more than just a monomer device, and its digital sampling has been decentralized to each electronic transformer, a merged unit, and a smart terminal, and the cooperation between these devices directly affects the action of digital preparation. behavior. The architecture of the prior art digitally processed system figure 1 Indicated....
