Description
Technical Field

[0002] Resource boards are used to provide functions such as data signal acquisition, excitation signal drive, and high-precision power supply.
[0003] Currently, in the applications of signal acquisition systems or semiconductor test systems, the resource board and the communication card board are generally connected by physically plugging the PCIE interface. However, this connection method has some problems: on the one hand, it is easy to cause signal loss; on the other hand, with the increase of the number of pluggings and unplugging, the physical interface will be worn, and non-standard plugging and unplugging may cause interface damage, such as broken pins or bent pins.
[0004] Currently, non-contact communication between boards can also be achieved between resource boards based on near-field communication (NFC). However, due to the limitation of the transmission distance, the transmission frequency of signals is usually low, which cannot meet the transmission requirements of high frequency and high bandwidth. In some improved technologies, guided NFC communication is used. For example, Texas Instruments has proposed a conical coaxial emission structure, which can meet the design requirements of different frequencies by correspondingly adjusting the physical size of the field limiter. However, this undoubtedly increases the design difficulty and makes the structure of the resource board more complex.
[0005] Therefore, there is an urgent need for a new communication connection method between resource boards to solve the above problems. Summary of the Utility Model

[0049] Please refer to Figures 1 to 4 , the first embodiment of the present utility model is:
[0050] The present utility model provides a resource board, including a board body, a processor, and a millimeter-wave communication module; the millimeter-wave communication module is connected to the processor; the millimeter-wave communication module is provided on the board body.
[0051] In this embodiment, by providing a millimeter-wave communication module on the resource board, wireless communication between resource boards based on millimeter waves is realized. In the signal transmission between boards, using millimeter-wave wireless communication to replace the existing NFC wireless transmission can not only eliminate the waveguide transmission structure of NFC, but also easily achieve impedance matching of signals, while shortening the signal transmission path and supporting higher transmission frequencies; in addition, millimeter-wave connection can also be compatible with larger board installation position tolerances and show strong mechanical vibration tolerance.
[0052] As a preferred specific implementation manner of this embodiment, as Figure 1 shown, the number of the millimeter-wave communication modules 3 is two, namely a millimeter-wave communication module A31 and a millimeter-wave communication module B32; the millimeter-wave communication module A31 is provided on one of the board surfaces of the board body 1, and the millimeter-wave communication module B32 is provided on the other board surface of the board body 1. That is to say, a millimeter-wave communication module is provided on each of the front and back surfaces of the board body, and the specific setting position is not limited and can be flexibly adjusted according to the internal circuit routing of the board body and other design or scenario requirements.
[0053] Designed in this way, the resource board can be realized to have a two-way (corresponding to the front and back surfaces respectively) wireless communication function. It is particularly suitable for application scenarios where three or more resource boards are arranged side by side, and wireless communication interaction based on millimeter waves can be realized between adjacent two resource boards, such as for transmitting control instructions and returning test data.
[0054] In some feasible specific examples, such as Figure 1 and Figure 2As shown, the millimeter wave communication module A31 and the millimeter wave communication module B32 are staggered on the board surface of the board body 1, that is, staggered back to back. Here, the staggered means that although the millimeter wave communication module A31 and the millimeter wave communication module B32 are respectively arranged on two different board surfaces of the board body 1, there is no overlapping part between the two relative to the plane where the board body 1 is located.
[0055] In some feasible specific examples, the millimeter wave communication module A and the millimeter wave communication module B are arranged overlappingly on the board surface of the board body. Here, the overlapping arrangement can be as follows: Figure 3 and Figure 4 As shown, the millimeter wave communication module A31 and the millimeter wave communication module B32 are completely overlapped relative to the plane where the board body 1 is located, that is, they are arranged back to back; they can also be partially overlapped. The specifics still depend on the specific usage scenario or circuit layout design.
[0056] As a preferred example of the above preferred specific implementation, the millimeter wave communication module A and the millimeter wave communication module B are "staggered" or "overlapped" on the center line of the length direction of the board body. Such a design is more conducive to the resource board to perform wireless communication based on the common and universal side-by-side setting, so that the millimeter wave communication modules of the boards can be aligned as much as possible to ensure tolerance to mechanical vibration deviation and improve communication quality.
[0057] In this embodiment, each millimeter wave communication module provided on the resource board includes a millimeter wave transmitting unit TX and a millimeter wave receiving unit RX; the millimeter wave transmitting unit TX and the millimeter wave receiving unit RX are connected to the processor respectively. It can be seen that the resource board of this embodiment can realize the full-duplex communication function of simultaneous reception and transmission based on one millimeter wave communication module.
[0058] Corresponding to the above preferred specific implementation, since a millimeter wave communication module is provided on both sides of each resource board, it is possible to realize that both sides of the resource board have full-duplex communication function, that is, bidirectional full-duplex communication function.
[0059] As a preferred specific implementation of this embodiment, the millimeter wave communication modules on the resource board are all millimeter wave communication chips. That is, each millimeter wave communication module is integrated with a set of RX / TX antennas in the form of chip integration. By integrating the antenna inside the chip, the size of the millimeter wave communication module can be made smaller, and then the size of the module used to realize the wireless communication function on the resource board can be made smaller, which is more conducive to integration; further, it can also free up more space for the board body on the resource board, making it more convenient for the resource board to design and integrate other electrical components / modules required according to different functional requirements, so as to achieve functional improvement.
[0060] As a preferred example of the above preferred specific embodiments, the millimeter-wave communication chip has front and back sides. A set of RX / TX antennas are integrated on the front side of the chip, which are responsible for transmitting / receiving millimeter-wave signals; on the back side, there are chip pins PAD, which are responsible for being fixed on the board body and realizing electrical connection with other components on the board body.
[0061] In the resource board of this embodiment, there is also a codec, and the millimeter-wave communication module is connected to the processor via the codec. The codec is used to encode the signals to be sent by the millimeter-wave communication module and decode the signals received by the millimeter-wave communication module. One resource board is correspondingly provided with one codec. Corresponding to the above preferred specific embodiments, millimeter-wave communication module A and millimeter-wave communication module B are respectively connected to the processor via the codec.

[0065] In addition, the number of communication boards configured in the board-to-board wireless communication system provided in this embodiment is determined according to the specific requirements of application resources.

[0067] If more than three resource boards need to be equipped, then a resource board with one millimeter-wave communication module configured on each of the front and back sides of each resource board is selected. That is, the resource board configuration described in the preferred specific embodiment of Embodiment 1 can be selected.
[0068] One feasible installation and use method corresponding to the above-mentioned configuration of more than three resource boards is as Figure 6 shown. It uses a daisy-chain substrate 4 as the insertion base plate of the resource board. More than three resource boards 2 are inserted in the daisy-chain substrate 4 side by side and aligned, and the design and reuse are very convenient. Corresponding to Figure 6 the communication interaction schematic diagram between the resource boards 2 of the installation and use method is as Figure 5As shown in Figure 5 and Figure 6 shown, preferably for two opposite resource boards, the millimeter-wave communication modules thereof also correspond to each other (are aligned) as much as possible, which can ensure the maximum tolerance for mechanical vibration deviation.
[0069] In some specific embodiments of this embodiment, as Figure 7 shown, the board-to-board wireless communication system further includes a power supply board, and the power supply board is respectively connected to each resource board ( Figure 7 as shown in the figure including multiple resource boards from card 1 to card N) to provide energy for each resource board separately. Preferably, an isolated power supply is further provided on the board body of each resource board; the power supply board is connected to the electrical components through the isolated power supply of each resource board.

The data board mainly acts as a central processing unit, responsible for sending relevant control instructions to the resource boards and processing the data returned by the resource boards.
[0071] In some specific embodiments of this embodiment, as Figure 7 shown, an external interface is further provided on the board body of each resource board, and the external interface is connected to a processor for providing an external communication function.
