Due to the working power that+5V25A power supply is data processing, this power fail can cause that data processing does not work, secondary radar systemic breakdown, cannot carry out state acquisition, fault diagnosis and weight computing, thus do not have in weights definition+5V25A power supply this.
V. the secondary radar softly fail procedure realized based on said system composition and weights definition is as follows:
1) state of data processing module to each LRU module of this passage carries out timing sampling;
2) define according to above-listed weights, calculate the fault total weight value of this passage in real time;
3) by the communication between binary channels, obtain the fault total weight value to square channel, the fault total weight value of this passage is informed square channel simultaneously;
4) arrange according to radar duty, determine whether switch between A channel, channel B.
Due to the difference of radar duty, the 4th) step comprises 2 kinds of situations: 1. allow to automatically switch; 2. forbid automatically switching (manual switchover).Radar can be set to allow automatically switch or forbid to automatically switch (manual switchover) according to the integrity of radar equipment, stability status by user.
Usually when equipment without any fault, stable, radar is set to allow automatically switch.Once there be fault to occur, radar can automatically switch according to real-time fault collection and trouble power result of calculation, and the reliability of such equipment is high and failure rate is minimum.
But in extreme circumstances, there is fault in 1 passage always, or A channel, channel B both have fault to occur, maintenance personal cannot be on the scene at once again and repair, at this moment best selection is set to by radar forbid automatically switching, user rule of thumb manually carries out passage bridge, makes radar be operated in normal channel or the lighter passage of fault.
Here is exactly realize the softening instantiation of the secondary radar system failure, and precondition the mode of operation of radar is set to " allowing to automatically switch ".
Example 1: when A channel does not have fault, A channel fault total weight value is zero;
During " Σ emissive power " fault of channel B, channel B fault total weight value is 51;
Accordingly, secondary radar will automatically switch to the A channel of normal work, and radar normally can export target information.
Example 2: when " Σ emissive power " fault of A channel, A channel fault total weight value is 51;
During " Ω emissive power " fault of channel B, channel B fault total weight value is 31;
Accordingly, secondary radar will automatically switch to the lighter channel B of fault, and radar falls index and uses, and can export target information, but due to channel B " Ω emissive power " fault, radar does not have Sidelobe Suppression function, can cause false alarm rate that normal condition is higher;
Example 3: when " Σ receiving cable " fault of A channel, A channel fault total weight value is 101;
" Δ receiving cable " fault of channel B, channel B fault total weight value is 80;
Accordingly, secondary radar will automatically switch to the lighter channel B of fault, and radar falls index and uses, and can export target information, but due to " Δ receiving cable " fault of channel B, radar does not have monopulse characteristic, and aimed at precision declines to some extent;
Example 4: when " Σ launches forward-wave " fault and " Σ emissive power " fault of A channel, A channel fault total weight value is 152;
" self-test signal source " fault of channel B, channel B fault total weight value is 31;
Accordingly, secondary radar, by automatically switching to the lighter channel B of fault, can export target information, but due to " self-test signal source " fault of channel B, channel B loses receiver self-checking function;
