Description

Technical Field

[0001] This invention relates to the field of radar power supply technology, and in particular to an anti-interference one-button digital coding system and method for radar power supply arrays. Background Technology

[0002] Radar power supply is one of the subsystems of a radar system, providing power to other subsystems and is a crucial component of the radar system. With the development of digitalization and intelligence, radars require increasingly larger power supplies and more diverse power types, placing new demands on the health management of the power supply subsystem. By encoding each power supply and reporting its operating status, and promptly reporting fault conditions in case of power supply failure, the intelligence level of the power supply array can be greatly improved.

[0003] There are currently two main methods for power supply array encoding. The first is hardware encoding via DIP switches. This method can distinguish the location of different power supplies, but when a power supply fails and needs to be replaced, the power supply needs to be opened and the DIP switches reset, which is inconvenient for system maintenance. The second method is power supply encoding via external address lines. This method increases the number of wiring connections in the system, significantly increasing the debugging workload and reducing production efficiency. The third method is software encoding via manual modification of the internal storage circuitry of the power supply. This method has no additional hardware cost, but when a power supply fails and needs to be replaced, the cover needs to be opened and the address information rewritten, which is also inconvenient for system maintenance. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to propose an anti-interference one-button digital coding system and method for radar power arrays. It sets up a master control power supply and several slave control power supplies, adds a coding enable output interface and a coding enable receiver interface to the array power supply, and sets the number of rising edge signals that can be changed under different interference environments. This avoids miscoding in complex electromagnetic environments, reduces labor costs, and improves coding reliability, production efficiency, and product reliability.

[0024] An anti-jamming one-button digital coding method for radar power arrays, implemented based on the aforementioned anti-jamming one-button digital coding system for radar power arrays, the method comprising:

[0025] The total number of radar power supplies, the number of rising edge signals, and the initial power supply code in the radar power supply array are set using the host computer interface and then transmitted to the main control processor in the main control power supply.

[0026] The main control processor stores the initial power supply code in the main control storage unit. After storage, the main control processor transmits the rising edge signal to the main control code enable output unit. The main control code enable output unit continuously outputs rising edge signals, and the main control power supply encoding is completed.

[0027] The slave control power supply's slave control encoding enable receiving unit receives the rising edge signal and transmits it to the slave control processor. After receiving the rising edge signal, the slave control processor sends an encoding request command to the master control bus communication unit in the master control power supply through the slave control bus communication unit.
