Description

Technical Field

[0001] The present invention relates to the technical field of hardware detection, and in particular, to a detection method, device and lighting device for a data distribution card. Background Art

[0002] Under normal circumstances, due to different performance characteristics of different products, there are generally different hardware designs. Further, in order to reduce the types of hardware designs, hardware compatibility designs for different products are adopted. However, even when the hardware is the same, different products still run different firmware, resulting in the need for manual download and differentiation. For example, the processing chip in the data distribution card is a Field Programmable Gate Array (FPGA for short). In a normal product system, this card may be installed on the left or the right. Then when it is installed on the left or the right, the direction of the data flow is different, and there are also differences in the internal processing logic. That is, when on the left, the right side of the data distribution card is the data flow input, and the left side is the data flow output. Conversely, when on the right, the right side of the data distribution card is the data flow output, and the left side is the data flow input. In such a conventional situation, the factory will download different firmware programs according to the installation position of the distribution card. Once the firmware program is installed incorrectly, it may damage the distribution card itself. Therefore, using the above method requires finding and matching the hardware installation position and manually matching the firmware.

[0024] Embodiment 1

[0025] According to an embodiment of the present invention, an embodiment of a detection method for a data distribution card is provided. Each data distribution card includes a field programmable gate array (FPGA) and a storage area. The storage area pre-stores an arbitration program and a firmware program, and the storage location of the firmware program corresponds one-to-one with the installation location of the data distribution card. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from that here.

[0026] Figure 1 Flowchart of the detection method for the data distribution card according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0027] Step S102: When the data distribution card is powered on, the FPGA loads the arbitration program to determine the installation location of the data distribution card;

[0028] Step S104: According to the installation location of the data distribution card, load the corresponding firmware program of the data distribution card.

[0029] Through the above steps, the arbitration program can be preferentially loaded to arbitrate the installation location of the data distribution card, and the corresponding firmware program of the data distribution card can be loaded according to the installation location of the data distribution card, achieving the purpose of automatically differentiating and loading different firmware programs without manual screening and matching, thus realizing the technical effects of effectively avoiding hardware application errors and board damage, improving efficiency, and eliminating potential hazards, and further solving the technical problem in the prior art that different firmware programs need to be manually searched and matched for the hardware installation location due to different products, and it is easy to damage the board once an error occurs.

[0030] In an alternative embodiment, before the data distribution card is powered on, the above method further includes: dividing the storage area into multiple program storage areas; respectively storing the arbitration program and the firmware program into the corresponding program storage areas.

[0031] The above storage area can be divided into multiple program storage areas, and an arbitration program and one or more firmware programs can be stored into the corresponding program storage areas. For example, the first program storage area is used to store an arbitration program, and the second to the Nth program storage areas are used to store one or more firmware programs respectively. It should be noted that the value of N above is a non-zero positive integer. Through the above embodiment, the storage location of the firmware program can also be made to correspond one-to-one with the installation location of the data distribution card.

[0032] In an alternative embodiment, dividing the storage area into multiple program storage areas includes: obtaining the number of arbitration programs and the number of firmware programs, where the number of firmware programs is determined according to the installation location of the data distribution card; determining the number of partitions of the storage area according to the number of arbitration programs and the number of firmware programs; dividing the storage area according to the number of partitions to obtain multiple program storage areas.

[0033] In the specific implementation process, the number of the above arbitration programs is one, and the number of the above firmware programs can be one or more, without any limitation in the specific implementation. Additionally, the number of firmware programs can be determined according to the installation location of the data distribution card. For example, the installation locations of the data distribution cards can be counted, and if the installation locations of the data distribution cards do not repeat, then the number of firmware programs can be calculated; further, by adding the number of arbitration programs and the number of firmware programs, the number of partitions of the storage area can be calculated; then, the storage area is divided using the number of partitions to obtain multiple program storage areas, that is, the storage area is divided into as many program storage areas as the number of partitions.

[0034] In an alternative implementation, the FPGA loads the arbitration program to determine the installation location of the data distribution card, including: the arbitration program determines the installation location of the data distribution card according to the pin voltage signal output by the video input card. Through the above implementation, the installation location of the data distribution card can be accurately determined using the pin voltage signal output by the video input card.

[0035] Optionally, when the pin voltage signal output by the video input card is that the first pin outputs a high level and the second pin outputs a low level, the installation location of the data distribution card is determined to be the first installation location; when the pin voltage signal output by the video input card is that the first pin outputs a low level and the second pin outputs a high level, the installation location of the data distribution card is determined to be the second installation location.

[0036] It should be noted that the number of pins of the video input card can be adjusted according to the number of data distribution cards, so as to achieve the determination of the installation locations of more data distribution cards.

[0037] A detailed description of an alternative implementation of the present invention will be given below.

[0038] The present invention adds an arbitration firmware program to the program storage area of the data distribution card, and this arbitration program can perform arbitration according to the installation location of the data distribution card to distinguish different firmware programs loaded by the data distribution card.

[0039] Figure 2 is a schematic diagram of the detection method of the data distribution card according to an alternative embodiment of the present invention. As Figure 2 shown, when the data distribution card is powered on, the FPGA loads the arbitration program, and the arbitration program will judge the installation location of the data distribution card according to the high and low levels of pins 1 and 2 output by the video input card. For example, when 1 is at a high level and 2 is at a low level, it is installed on the left side, and when 1 is at a low level and 2 is at a high level, it is installed on the right side. The arbitration program will perform secondary program startup and loading according to the installation location of the data distribution card, and load the firmware program on the corresponding side.

[0040] Figure 3It is a schematic diagram of the program storage area of the data distribution card according to an alternative embodiment of the present invention. As Figure 3 shown, for each data distribution card, one that can be divided into three program storage areas can be adopted. When the data distribution card is produced, three programs are downloaded and stored. Each time it is powered on, the data distribution card preferentially loads the arbitration program. After arbitration, secondary loading is started, and the left program (corresponding to the above arbitration program) or the right program (corresponding to the above arbitration program) is loaded according to the installation position of the data distribution card, thus eliminating the need for manual identification and matching.
