Distribution type deserializing control structure and control method

Abstract

The invention discloses a distribution type deserializing control structure which is characterized in that each radio frequency channel comprises a deserializing control chip with a chip ID number. The deserializing control chip is used for comparing a channel ID number issued by a system beam controller and a chip ID number and independently controlling attenuation and phase shifting on a single radio frequency channel. The system beam controller is connected with each T / R assembly through an SPI bus. The SPI bus comprises three connection wires, namely a synchronous clock CLK, a serial data SN and an enabling EN. A distribution type structure is used for replacing an integrated control structure, the deserializing control chip with the chip ID is used in the structure so as to greatly reduce the connection wires among the assemblies, control on single unit of the assemblies is achieved, and universality of the T / R assemblies in a system and reliability of the system are greatly improved.

Description

technical field [0001] The invention relates to the field of digital control of precision electronic equipment, in particular to a distributed serial-to-parallel conversion control structure and control method. Background technique [0002] Efficient digital control of end sensors in complex and sophisticated electronic devices has until now been a problem. Assuming that each radio frequency channel requires X-bit digital attenuation and digital phase-shift data, the system beam controller needs to issue a total of M×N×X data. Through the existing centralized control structure, the system beam controller needs M×N× Only X connecting lines can independently control the attenuation and phase shift of each channel. There are many connecting lines, which increases the difficulty of system integration and reduces the reliability of interconnection between components in the system, thereby increasing the system failure rate; therefore, The existing centralized control method has ...
