[0002] Most of the feeder terminal test benches currently launched on the market are often only suitable for arrival inspection, sampling inspection, etc., and the main users are testing institutions and testing centers. For manufacturers, controlling the factory quality of feeder terminals is the top priority, but there are few factory test benches for feeder terminals, and the market demand is large.

[0003] Defects and shortcomings of existing technologies:

[0004] (1) Currently, there is a lack of effective means for hardware testing of feeder terminals. Hardware testing and precision calibration are performed manually, with low automation and production efficiency.

[0005] (2) Existing feeder terminal testing stations are mainly used for delivery testing. Most of them use the delivery testing stations to implement the function testing of the factory feeder terminals, but they cannot cover the hardware testing of the factory feeder terminals.

[0006] (3) The existing feeder terminal factory test station generally only supports single-unit testing, with low testing efficiency and cannot perform batch testing. Utility Model Content

[0007] In order to solve the problems existing in the prior art, the utility model proposes a complete machine factory parallel testing platform suitable for feeder terminals. In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A complete machine factory parallel testing platform for feeder terminals, including an operation cabinet and more than two low-voltage test cabinets.

[0010] The barcode scanner and switch are connected to the computer respectively, and the serial port server is connected to the switch;

[0011] The three-core standard aviation plug interface and the twenty-six-core standard aviation plug interface are respectively connected to the relay protection tester; the relay protection tester and the network port interface are respectively connected to the switch, the relay protection tester is also connected to the signal indicator light, and the serial port interface is connected to the serial port server.

[0012] Preferably, there are five low-voltage test cabinets.

[0013] Preferably, the number of the network port interfaces is two.

[0014] Preferably, the number of the serial port interfaces is two.

[0015] Preferably, the number of the three-core standard aviation plug interfaces is two.

[0016] Beneficial effects:

[0017] (1) Efficient and fast: It supports simultaneous access to multiple feeder terminals and independent testing, which is suitable for completing batch testing tasks and greatly improves work efficiency.

[0018] (2) Support hardware function testing. A relay protection tester and a standard aviation plug interface are assembled on the test cabinet to test the hardware.

[0019] (3) Compared with manual inspection, automatic inspection of the platform can complete several times the production tasks of manual inspection in the same time. It can not only control the production quality of the feeder terminal, but also shorten the production hours, greatly reducing the production cycle of the feeder terminal.
