Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The present invention is mainly aimed at the realization of the interface board of the radar wave control and monitoring self-test platform based on the VPX bus. The wave control extension or monitoring extension to be tested sends a specific function test instruction, and the wave control extension or monitoring extension returns the feedback information to execute the instruction through the interface board, thus completing the test of the specific function.

[0038] VPX is a new-generation bus standard based on high-speed serial bus. It adopts Multi-GigRT2 connector that supports high-spe...

Abstract

The invention discloses a VPX bus-based general interface board of a radar wave control and monitoring self-test platform. The interface board is provided with a 6U-structure VPX high-speed bus interfaces, namely, VPX connectors P1 to P6; the VPX connectors P1 to P6 provide 192 pairs of differential pairs including 12 paths of RS422 / 485 transmitted differential pair signals, 172 paths of RS422 / 485 received differential pair signals and 1 reserved path of 4X SRIO high-speed differential pair signals; and the VPX connectors P1 to P6 provide also provide 48 single 8-ended signals including 8 paths of TTL long-distance driving output signals, 8 paths of LVTTL driving input signals, 8 paths of LVTTL driving output signals, 8 paths of CMOS driving output signals, and 16 paths of analog detection input signals. With the VPX bus-based general interface board of the radar wave control and monitoring self-test platform of the invention adopted, the generalized design of phased array radar control and monitoring self-test platform interface boards of different scales can be realized, the diversification requirement of the wave control and monitoring self-test platform can be satisfied; and once being designed, the interface board can be re-used, and therefore, a development period can be shortened, and development costs can be reduced.

Description

technical field [0001] The invention relates to an interface board belonging to the technical field of phased array radar wave control and monitoring testing, in particular to a general interface board of a radar wave control and monitoring self-test platform based on a VPX bus, wherein VPX is based on a high-speed serial The next-generation bus standard of the row bus adopts the Multi-Gig RT2 connector that supports high-speed differential signals to obtain higher transmission speed and more I / O pins. Background technique [0002] Both wave control unit and monitoring unit are important components of phased array radar. On the one hand, the wave control unit receives and forwards the wave control code and control sequence to the next-level microwave radio frequency component, and on the other hand, receives and reports the status information to the upper-level control unit; On the other hand, collect, analyze, and report the status of the entire radar to the terminal subsy...
