Example Embodiment

[0010] The main control and protection processing unit adopts the ARM architecture processor, and the T / R components adopt the ARM+FPGA processor architecture. The main peripheral interfaces involved are GPIO, IIC, UART, CAN, Ethernet, and ADC. The real-time monitoring status indicators inside the T / R component include pulse current, temperature, excitation power, output power, reflected power, pulse voltage, pulse width period, and pulse width duty cycle. In this design, ARM selects the TM4C1294NCPDT chip, which is mainly responsible for monitoring status indicators and taking control and protection measures. The chip integrates a wealth of peripheral interfaces to meet the needs of data communication and protection control in the system. FPGA selects XC6SLX9-2CSG324I, which is mainly responsible for analyzing pulse width period signals, obtaining pulse width period and duty cycle indicators, and also responsible for completing beam control and STC control.

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...
