Problems solved by technology

[0004]In addition, another test system (not shown) considers using the receiving card with the same number of network ports to be tested as the sending card, so that each The network port is connected to a receiving card, so that when the network port test is performed, the network port to be tested can be tested at the same time, but this method requires the participation of multiple receiving cards. If the number of network ports to be tested in the sending card is too large, it will Increased testing cost input
The above two ways of testing are inefficient

Embodiment 1

[0055] figure 2 It is a schematic flowchart of a method for testing a network port of a sending card provided in Embodiment 1 of the present application, and the method is applicable to testing a network port of a sending card.

[0056] It should be noted that the sending card includes an even number of network ports to be tested. Before testing the network ports to be tested on the sending card, each network port to be tested can be numbered in advance according to the setting position of the network port to be tested. Each network port to be tested has a corresponding network port number, and the network port numbers of each network port to be tested are recorded as 1˜2n in sequence, and n is greater than or equal to 1. In addition, before the sending card performs the test of the network port to be tested, each network port to be tested needs to be connected according to a given method. Specifically, the network port to be tested with the network port number 1 is connected...

Embodiment 2

[0069] image 3 It is a schematic flow diagram of a network port testing method of a sending card provided in Embodiment 2 of the present application. Embodiment 2 of the present application is optimized on the basis of the above-mentioned embodiment. The network port to be tested determined as the sending signal network port in the mouth is embodied as: the network port to be tested with the network port number 1 as the first sending signal network port; the network port to be tested with the network port number 2n as the second sending signal network port; A signal network port; one of the two network ports to be tested in each pair of network ports to be tested is selected as the third network port for sending signals.

[0070] At the same time, this embodiment further sends the test signal data generated by the sending card to the receiving signal network port correspondingly connected by the network cable through each of the sending signal network ports, and receives the ...

Embodiment 3

[0108] Figure 4 A structural block diagram of a test system provided by Embodiment 3 of the present invention, such as Figure 4 As shown, the test system includes: sending card 31 and receiving card 32,

[0109] Sending card 31 comprises an even number of network ports 311 to be tested ( Figure 4 Take 8 network ports to be tested as an example), the network port numbers of each network port 311 to be tested are recorded as 1~2n in turn, and n is greater than or equal to 1; the receiving card 32 includes a sending network port 321 and a receiving network port 322; The network port 311 to be tested with the network port number 1 is connected to the sending network port through a network cable, and the network port 311 to be tested with the network port number 2n is connected to the receiving network port 322 through a network cable; the network port number of the sending card 31 is 2~ The 2n-1 network ports 311 to be tested are adjacently divided into n-1 network port pairs...

Abstract

The invention discloses an internet port test method and test system for a sending card, and the method comprises the steps that: the sending card enters an internet port test mode after the sending card is powered on and started, and determines a to-be-tested internet port serving as a sending signal internet port from all to-be-tested internet ports; the sending card sends the generated test signal data to a receiving signal network port correspondingly connected with a network cable through each sending signal network port, and receives feedback data returned through each receiving signal network port; and the sending card compares each feedback data with the corresponding test signal data, and determines a test result of each to-be-tested network port according to a comparison result.By means of the method, spontaneous testing of the to-be-tested internet port on the sending card is achieved, frequent switching of network cable connection in the testing process is reduced, meanwhile, the number of receiving cards used in the testing process is reduced, the whole testing process is simple and convenient, and the testing efficiency of the sending card internet port is effectively improved.

Description

technical field [0001] The application relates to the technical field of board card testing, in particular to a method and system for testing a network port of a sending card. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) all-in-one machine specifically integrates a receiving card, a backlight module, and a power conversion. In practical applications, the LED all-in-one machine can realize signal display through interaction with the sending card. Specifically, the sending card can interact with the control system of the LED all-in-one machine through its own network port. The interaction form of the sending card specifically includes the sending of control commands, signal data transmission, and the feedback and reception of control system status results. It can be seen that the sending card occupies a key position in the display realization of the LED all-in-one machine. For the sending card, before the sending card leaves the factory, t...
