Abstract
The invention relates to a radar antenna power source failure detection circuit. With wide application of phased-array antennas in radars, failure detection of antenna power sources becomes more and more important, the power source scale of the phased-array antennas is usually in direct proportion to the number of transmitting and receiving (T/R) assemblies, when the T/R assemblies are up to hundreds, a power source system is relative large, the detection of power source failures is complex, and abnormal works of the T/R assemblies are directly caused by the power source failures. The radar antenna power source failure detection circuit is sequentially composed of a signal conditioning circuit, a multiplexer, an analog-to-digital conversion circuit, a single chip computer and an RS-485 interface circuit in series, wherein the multiplexer, the analog-digital conversion circuit and the single chip computer are respectively connected with a complex programmable logic device (CPLD) inner logic circuit. According to the radar antenna power source failure detection circuit, real-time detection of power sources can be achieved, failures can be detected in time, the failures can be positioned to least recently used (LRU) to guide maintenance men to carry out component changing and maintenance, and the radar antenna power source failure detection circuit is simple in structure, and low in cost.
Description
Technical field
The present invention relates to a kind of radar antenna power failure detection circuit.
Background technology
Extensive utilization along with phased array antenna in radar, the fault detect of antenna power becomes more and more main, the power supply scale of phased array antenna often and transmitting-receiving how much being directly proportional of (T/R) assembly, when the T/R assembly reaches up to a hundred, power-supply system is relatively huge, power failure monitor is also more complicated, and power fail will directly cause T/R assembly operation irregularity, therefore designs a complete power failure detection circuit very main.
Summary of the invention
Technical matters solved by the invention is to provide a kind of in real time power supply the implementation and monitors, and in time realizes fault, and to LRU, the guide maintenance personnel carry out the radar antenna power failure detection circuit that changes the part maintenance with localization of fault.
For solving above-mentioned technical matters, the technical scheme that the present invention takes:
A kind of radar antenna power failure detection circuit, its special character is: be made of the signal conditioning circuit, multiplexer, analog to digital conversion circuit, single-chip microcomputer, the RS-485 interface circuit that are connected in series successively, multiplexer, analog to digital conversion circuit, single-chip microcomputer are connected with the CPLD internal logic circuit respectively.
Above-mentioned CPLD internal logic circuit adopts the ispLSI1016E of LATTICE company.
Above-mentioned single-chip microcomputer adopts the AT89C55 that selects atmel corp.
Compared with prior art, the present invention can carry out monitoring to power supply in real time, in time realizes fault, and to LRU, the guide maintenance personnel carry out and change the part maintenance with localization of fault, and circuit structure is simple, and is with low cost.
