T/R component control and monitoring method based on ARM and FPGA architectures

Abstract

The invention belongs to the fields of radar and control protection, and particularly relates to a fault monitoring and control protection method for T / R components in a phased array radar system. Themethod comprises the steps of master control protection module control and monitoring, control fault detection, frequency synthesizer control fault detection and power source fault detection for theT / R components. The method is characterized in that a single module can carry out self-detection and, in response to a fault, take a self-protection measure in time; and a master control protection module collects state information and fault information of the modules on different levels through polling, completes fault diagnosis, judges whether secondary protection measures are to be carried outor not, and reports information in a centralized manner. Through the control protection method comprising level-by-level querying, real-time response, centralized diagnosis and uniform reporting, timeexpenditures of the modules in responding to the faults can be reduced to the largest extent, the modules can work safely and reliably, and the signal stability in an environment with strong electromagnetic interference can be improved.

Description

technical field [0001] The invention belongs to the field of radar control and protection. Background technique [0002] At present, there is still a large gap between China and advanced countries in terms of generalized testing and troubleshooting. This is manifested in: lack of standardized standards, small monitoring range, backward technical means, lack of compatibility, poor system expansion capabilities, and fault diagnosis. The low efficiency has brought a series of problems to R&D and production, commissioning and verification, and maintenance maintenance. According to relevant research, advanced fault monitoring technology can greatly improve maintenance efficiency, increase fault isolation rate by more than 30%, and save more than 20% of follow-up maintenance expenses. Advanced fault monitoring system can effectively improve and guarantee system performance, so more and more By the country's attention and continuous development. Each antenna unit channel of the a...

Problems solved by technology

Due to the large number of internal modules, the monitoring of module status should minimize the system size and additional communication equipment overhead. Traditional T / R component fault monitoring and control adopts the communication bottom layer as Ethernet, which requires additional network equipment. Further Increased the complexity of the system, and once the centralized switch is destroyed, the fault monitoring of all devices will be paralyzed
