Abstract
The invention belongs to flight control system BIT (built in test survey) technology, when being related to a kind of multiple tests while producing same BIT test commands, pair simultaneously to same equipment produce test command multiple testing setup priority, if multiple tests are all not carried out, the test command exported is 0；If only one test is carrying out, test command caused by the test is exported；If multiple tests are performing simultaneously, test command caused by the test of output priority highest.Of the invention in multiple tests synchronous progress, flight control system can select the test execution of current highest priority, and the response, selection and switching to test command are all real-time and orderly, and running software sequential is clear.Realize that complexity is low, reliability is high, substantially increases the reliability and testability of system.
Description
Technical field
The invention belongs to flight control system BIT (built in test survey) technology, is related to a kind of multiple tests while generation is same
During one BIT test command, to the method for BIT test commands selection.
Background technology
The BIT testing sequences of traditional flight control system perform, in the absence of the situation for carrying out multiple tests simultaneously, but with
The type and function for flight control system BIT maintenance tests are continuously increased, and have been occurred in the flight control system of civil aircraft
The situation of BIT tests is concurrently performed, the BIT tests concurrently performed may produce same item test instruction, traditional design side
Method can not realize the real-time selection of the multiple BIT test instructions concurrently performed.
The content of the invention
The purpose of the present invention is：It is proposed it is a kind of realize it is convenient, can be from concurrently performing for same item test instruction can be produced
The method of selection test instruction in multiple BIT tests.
The technical scheme is that：A kind of BIT test command systems of selection based on priority, pair simultaneously set to same
The standby multiple testing setup priority for producing test command, if multiple tests are all not carried out, the test command exported is
0；If only one test is carrying out, test command caused by the test is exported；If multiple tests are performing simultaneously,
Then test command caused by the test of output priority highest.
The described BIT test command systems of selection based on priority, its step are as follows：
Step 1：Flight control computer receives the instruction into service mode
Step 2：Flight control computer is to that can produce multiple testing setup priority to same equipment test command simultaneously；
Step 3：Signal selector judges to test whether to be carrying out step by step since the test of lowest priority, if having more
It is high preferential
The test of level is carrying out, and is selected to the test for being devices under exporting higher level priority；If do not test just
Performing then
It is 0 to output result is devices under；
Step 4：After the instruction of service mode is exited in flight control computer reception, test terminates, and refers to using 0 as the test exported
Order.
The described BIT test command systems of selection based on priority, for priority by 1 to n integer representation, 1 represents excellent
First level is minimum, next to that 2,3 ..., n represent highest priority.
The described BIT test command systems of selection based on priority, test execution state is levied with a Boolean type scale：
0 expression test is not carried out, and 1 expression test is carrying out.
It is a kind of based on priority BIT test commands selection system, including flight control computer (1), signal selector (2),
It is devices under (3), flight control computer receives the instruction into service mode and sets the priority of each test, signal selector
The test signal of the priority selection highest priority of each test set according to flight control computer is exported to being devices under.
The present invention has the advantage that and beneficial effect：Maintenance test is opened by ground maintenance personnel by ground-support device
It is dynamic, and detection signal is sent to flight control system.In the synchronous progress of multiple tests, flight control system can select currently
The test execution of limit priority, response, selection and switching to test command are all real-time and orderly, running software sequential
Clearly.Realize that complexity is low, reliability is high, substantially increases the reliability and testability of system.
Brief description of the drawings
Fig. 1 is a kind of logic chart of the BIT test command systems of selection based on priority of the present invention；
Fig. 2 is the logic chart of signal selector in a kind of BIT test command systems of selection based on priority of the present invention.
Embodiment
Below so that left inside aileron safeguards the enabled order of state as an example, the specific implementation step of this method is carried out specifically
It is bright：
Left inside aileron safeguards that the enabled order of state (value is 0 or 1) can be by " remote unit monitoring test " and " port aileron is comprehensive
Two tests that can concurrently perform of conjunction test " produce.Wherein " remote unit monitoring test " execution Status Flag is reu_mon_
Tst_tip (0 expression test is not carried out, and 1 expression test is carrying out), " port aileron integration test " execution Status Flag is ail_
L_intg_conf_tst_tip (0 expression test is not carried out, and 1 expression test is carrying out)；
1. flight control computer receives the instruction into service mode
2. setting the priority of remote unit monitoring test as 1, the priority of port aileron integration test is 2；
3. if reu_mon_tst_tip be 1 if select remote unit monitoring test test caused by test instruction (0 or
1) first order selection result is used as, otherwise takes 0 to be used as first order selection result；
4. test instruction caused by port aileron integration test is selected to make if ail_l_intg_conf_tst_tip is 1
(0 or 1) is instructed for the test of output, otherwise takes test instruction of the caused first order selection result as output in 3..
5. after exiting service mode, the test instruction exported is used as using 0.
Pair simultaneously to same equipment produce test command multiple testing setup priority, if it is multiple test all do not hold
OK, then the test command exported is 0；If only one test is carrying out, test command caused by the test is exported；Such as
The multiple tests of fruit are performing simultaneously, then test command caused by the test of output priority highest.The present invention is same in multiple tests
When step is carried out, flight control system can select the test execution of current highest priority, response to test command, select and cut
It is all real-time and orderly to change, and running software sequential is clear.Realize that complexity is low, reliability is high, and substantially increase system can
By property and testability.
