Description
Technical field
The invention belongs to field of radar, further relate to the data collecting field of radar, specially a kind of radar it is complete
Life cycle monitors system.
Background technology
In order to which the producing cause of failure is accurately positioned and found to radar fault, the full Life Cycle to radar is needed
Phase activity is recorded, and judges whether radar lives through the activity for influencing his function, however there is no especially effectively reliable at present
Means.
Traditional data acquisition modes are manual records, and Radar Products are during being sent to army, if are lived through super
Cross the big vibrations of regulation amplitude, if live through high temperature low temperature environment, in army's course of work, by operator to its environment into
Row record, but due to the unreliability of artificial clerking, it is impossible to the data are accurately recorded.When radar generates
It when failure, needs to investigate component one by one, according to insecure artificial clerking, conjecture may lead to the original of failure
Cause, in short, previous data collecting system is very unreliable, and workload is huge！

Data storage is realized according to storage computer, in case subsequent query.
Advantageous effect
The present invention utilizes sensor by environment real time value, then will be more than the numerical value of threshold value by data processor
It is filtered, obtains particular surroundings numerical value.The particular surroundings residing for radar is monitored in real time using multiple sensors, and will
This particular surroundings quantizes, and due to the military security characteristic of radar, needs that transmission is encrypted to these data, storage side is received
It is decrypted after to data, restores particular surroundings value, stored.The encryption method be using storage side public key carry out it is non-
Symmetric cryptography.
Compared with prior art, the beneficial effects of the present invention are can be monitored to the Life cycle of radar, in real time
Control the ambient condition of radar；The case where especially breaking down to radar has outstanding advantage, by large quantities of radar progress
Long term monitoring, it is for statistical analysis to failure, the state that takes place frequently of radar fault may further be summed up, when delivering for a check
The failure is handled, the generation of failure is reduced.
