Radar time sequence control system based on CAN bus

Abstract

The invention discloses a radar time sequence control system based on a CAN bus. The radar time sequence control system comprises the CAN bus and a plurality of CAN nodes, only one CAN node is shown in a figure 1, and other CAN nodes are identical to the CAN node in connecting mode and structure. Each CAN node comprises a CAN bus communication module, a time sequence control module, an input-output module, a target simulation module, a photoelectric conversion module and a voltage-stabilized source module. Radar time sequences and a whole radar network are organically fused, so that the radar time sequence control system is very suitable for the requirement for information intensive control development, can decrease a lot of communication modes and is simple in structure and capable of adapting to severe environments. In addition, compared with existing serial ports and other serial buses, the CAN bus can achieve data transfer diversity (the serial ports can only achieve point-to-point transmission), the real-timeliness is good, a transmission distance is long, and the transmission rate is guaranteed under the condition that the transmission distance is considered.

Description

technical field [0001] The invention relates to the technical field of radar timing control systems, in particular to a CAN bus-based radar timing control system. [0002] Background technique [0003] The radar timing control system is the communication control center of all important nodes of the entire radar, which generates and forwards the timing signals required by each sub-equipment. With the rapid development of modern radar technology and the continuous improvement of system integration, the core part of the signal timer consists of a large number of small-scale logic integrated circuits and gradually develops into a highly integrated field programmable gate array (FPGA) circuit. [0004] CAN bus has high network security and reliability, is simple and practical, and has low network cost. It has become the mainstream bus of automotive electronic systems. Another advantage of the CAN bus is that it is especially suitable for occasions where the ambient temperature ...

AI Technical Summary

Problems solved by technology

Limited by factors such as weak anti-interference ability and poor signal quality, the transmission speed of traditional single-ended signals has reached the limit and cannot meet the needs of high-speed control. Traditional single-ended signal transmission will gradually withdraw from the mainstream of signal interconnection
