Description

Technical Field

[0001] The present invention relates to the field of radar detection, and in particular to a health management module in a beamforming chip. Background Art

[0002] The digital beamforming (DBF) system is a key subsystem in digital array radars that can achieve simultaneous multi-beam scanning. DBF systems usually use field programmable gate arrays (FPGAs) or beamforming chips to achieve multi-beam synthesis. Compared with FPGAs, beamforming chips have more advantages in large-scale digital array multi-channel, large bandwidth and multi-beam application scenarios.

[0003] The beamforming chip receives multi-channel data simultaneously to form multiple beams in real time. For large-scale digital arrays, failure of some components on the array is inevitable. If the beamforming chip does not consider health management, when the received channel data is abnormal, it will cause chip processing errors, which will cause the performance of the entire DBF system to decline or even lose its function, which is unacceptable in engineering. Therefore, health management is particularly important for beamforming chips, which is the key to long-term stable and reliable operation of the chip. Summary of the invention

[0004] In order to solve the existing technical problems, the present invention provides a health management module in a beamforming chip.

[0005] The specific contents of the present invention are as follows: A health management module in a beamforming chip includes a channel information acquisition module, a channel status judgment module and a channel validity judgment module. The channel information acquisition module collects multiple status information of each channel in real time and sends it to the channel status judgment module; the channel status judgment module judges and marks the channel status, and the channel status is sent to the channel validity judgment module; the channel validity judgment module judges whether each channel participates in the beamforming processing in the chip, and for channels with abnormal status, the channel is set to invalid.

[0006] Further, 1 to N channel data are input to the channel information acquisition module, and the channel information acquisition module processes each channel data separately to acquire multiple types of channel status information 1 to M, where M and N are positive integers greater than 1.

[0007] Furthermore, the channel status judgment module judges the channel status by matching the configurable fault library. When one or more status information of the channel matches the configurable fault library, the channel status mark is set to 0, indicating that the channel is abnormal; when all status information does not match, the channel status mark is set to 1, indicating that the channel is normal.

[0008] Furthermore, the channel input validity judgment module receives the channel status mark information of each channel, and performs an AND operation on the valid signal of each channel and the channel status mark of the corresponding channel. When the channel status mark of a signal is 1 and a valid signal is input, the channel input is set to valid, otherwise it is invalid. The channel set to invalid does not participate in the beamforming in the chip.

[0009] The present invention adopts the methods of channel information collection, channel status judgment and channel effective signal shutoff to prevent abnormal channel data in the chip from participating in beamforming processing, thereby effectively improving the reliability of the beamforming chip. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The specific implementation of the present invention will be further explained below in conjunction with the accompanying drawings.

[0011] Figure 1 A block diagram of a health management method in a beamforming chip of the present invention; Figure 2 This is the schematic diagram of the channel status judgment module; Figure 3 Schematic diagram of the channel input valid judgment module. DETAILED DESCRIPTION

[0012] Combination Figure 1-Figure 3 , the block diagram of the health management module in the beamforming chip of the present invention, the module includes three modules: channel information acquisition, channel status judgment and channel validity judgment. The function of each module is introduced as follows: Channel information acquisition module 1: used to collect multiple status information of each channel in real time; Channel status judgment module 2: judges the channel status by matching the configurable fault library. When one or more status information of the channel matches the configurable fault library, the channel status mark is set to 0, indicating that the channel is abnormal. When all status information does not match, the channel status mark is set to 1, indicating that the channel is normal. Channel validity judgment module 3: used to judge whether each channel participates in the beamforming processing in the chip, and for channels with abnormal status, the channel is set to invalid.

[0013] The implementation method and steps of this method are as follows: a. 1~N (N is a positive integer greater than 1) channel data are input into the channel information acquisition module 1, and the channel information acquisition module processes each channel data separately and collects multiple types of channel status information 1~M (M is a positive integer greater than 1); b. The M types of channel status information of each channel are sent to the channel status judgment module 2. The channel status judgment module matches and judges the M types of status information of each channel based on the configurable fault library. If a match is made, the output channel status mark is 0. If the match fails, the output channel status mark is 1. c. Send the N channel status marks to the channel validity judgment module, perform an AND operation on the valid signal of each channel and the channel status mark of the corresponding channel to complete the validity judgment of each channel.

[0014] To implement this method, we combine Figure 1 , Figure 2 , Figure 3 The present invention is described in further detail.

[0015] Figure 1 Taking 16 input channels as an example, the interconnection diagram of channel information acquisition module 1, channel status judgment module 2 and channel validity judgment module 3 is given. The 16 channel data are input to the channel information acquisition module 1, and the channel information acquisition module 1 collects 4 types of channel status information ①~④ for each channel and sends the collected information to the channel status judgment module 2.

[0016] Figure 2 The principle block diagram of the channel status judgment module 2 is given. The channel status judgment module 2 receives the status information of 16 channels, and each channel has ①②③④ types of status information. The configurable fault library is configured with fault information with channel status information ④ being 1, and the fault information is sent to the 16-channel fault matching module. For the first channel, the channel status information ①~④ are all 0, which does not match the fault information, so the output channel status mark of the first channel is 1; for the second channel, the channel status information ①~③ are 0, which does not match the fault information, but the channel status information ④ is 1, which successfully matches the fault information, so the output channel status mark of the second channel is 0, and so on, and the 16-channel channel status information is output to the channel input valid judgment module 3.

[0017] Figure 3 The principle block diagram of the channel input validity judgment module 3 is given. The channel input validity judgment module 3 receives 16 channel status mark information. The first channel status mark is 1. After the first channel input is effectively ANDed, the first channel input is set to valid; the second channel status mark is 0. After the second channel input is effectively ANDed, the second channel input is set to invalid; and so on, the valid or invalid status of the 16 channels is output to the beamforming chip for subsequent processing. The channel with abnormal input is set to invalid, and this channel does not participate in the beamforming in the chip. The reliability of chip processing is improved through health management methods.

[0018] The present invention adopts a health management module and method for channel multi-information collection and shutting down abnormal channels based on fault library matching, which has high reliability. The beamforming chip can tolerate various errors in array components or input channels, such as: channels with high bit error rate; channels with incomplete frame structure; channels with abnormal data length, etc.; the fault library can be configured, which has strong versatility and can be applied to various application scenarios.
