Abstract
The invention belongs to the civil aviation flight control system safety testing technology, relating to the parallel safety testing method for testing multiple identical-model LRU components on a plane. The LRU is a locale replaceable unit, an important component of a flight control system of a plane; because the safety test directly affects safety of the flight control system and the test result directly affects a dispatching rate of the plane. A sequence test method is adopted for safety test on multiple identical parts on the plane. The invention provides a multi-LRU parallel safety testing method. The multi-LRU parallel safety testing method uses coding, decoding and a bit logic operation method to realize parallel testing of multiple identical components, reduces system resource consumption, improves safety testing efficiency and supports improving the dispatching rate of the plane.

The method of component in parallel test.
Background technology
LRU is Field Replaceable Unit, aboard the important component part of flight control system.At present, civil aircraft parts
Security test be boat after BIT test a part, belong to the important component part of flight control system maintenance function module.Due to
Security test directly affects the safety of flight control system, and what its test result directly affected aircraft sends rate, therefore, how to carry
The efficiency of high security test, is an important research direction of civil aircraft flight control system maintenance function.At present, on aircraft
The security test of multiple same parts, the main method using sequential testing, the testing time is long, wastes system resource, is fall
One of low aircraft many factors sending rate.
Summary of the invention
The technical problem to be solved is: propose a kind of many LRU parallel safety method of testing, to reduce system
Resource consumption, improves the efficiency of security test, sends rate to provide support for improving aircraft.
One many LRU parallel safety method of testing of the present invention, for carrying out parallel peace to multiple identical LRU parts
Full property test, the method comprises the following steps:
Step 1, the N road binary data signal of M LRU parts of Real-time Collection, after receiving test initiation command, according to
Quantity M of LRU parts, encodes described data signal, generates the integer variable of N number of M figure place, and is stored in variable list
In；
Step 2, according to the security test requirement of LRU parts, is utilized respectively a logical operations same road to M LRU
Signal condition judges, generates the test result integer variable of N number of M figure place according to judged result；
Step 3, is decoded computing to each test result integer variable, exports the N drive test examination of each LRU parts respectively
Result data signal.
The invention has the beneficial effects as follows: propose a kind of many LRU parallel safety method of testing, utilize coding, decoding and position
Logical calculation method, it is achieved that the concurrent testing of multiple same parts, reduces system resources consumption, improves the effect of security test
Rate, sends rate to provide support for improving aircraft.
Detailed description of the invention
Below the present invention is described in further details.A kind of security test software design approach based on model, profit
With coding, decoding and position logical operations, it is achieved the concurrent testing of multiple identical LRU, the step performing security test is as follows:
Step 1, gathers the multichannel data signal of multiple LRU parts, after receiving test initiation command, according to input data letter
All data signals are encoded by the quantity of number type, generate multiple integer variables according to signal type, this integer variable
Binary coding figure place is identical with LRU quantity, and number is identical with the quantity of input data signal type.All integer variables are deposited
Storage is in software variable list.
Step 2, according to the step of this LRU piece safety test request, is utilized respectively a logical operations to multiple LRU's
Multiple signals state judges, provides testing procedure according to judged result and is fully completed the multiple integers needed for the output of rear system
Variable, the binary coding figure place of this integer variable is identical with LRU number, the outputting data signals needed for quantity and test result
The number of type is identical.
Step 3, according to the step of this LRU piece safety test, order performs the universal safety for single LRU parts
Property test program, output multi-channel data signal.
Step 4, is decoded computing according to the multiple integer variables in step 2, exports the multichannel of multiple LRU parts respectively
Data signal, indicates the different test results of multiple LRU parts.
The operation principle of the present invention is:
Utilize the concordance of multiple identical LRU parts, use coded method the input signal of multiple same parts to be carried out
Packing processes, and after reducing data volume, utilizes position logical operations to complete the universal test program of single parts, utilizes position logic simultaneously
Computing, according to the different conditions of different parts, is decoded output signal processing, it is achieved multiple same parts concurrent testings,
Draw the different test results of multiple parts.
Embodiment 1
19 identical LRU parts of certain civil aircraft flight control system are performed security test.
1, gather 8 kinds of data messages of 19 LRU parts, according to the type of data message, after receiving test initiation command,
Its all data messages are encoded, forms the signal variable of 8 19, be stored in software variable list.
2, according to 3 testing procedures defined in maintenance function framework, utilize position logical operations 8 to 19 LRU parts
Plant signal condition to judge, provide 3 testing procedures according to judged result and be fully completed 6 19 needed for the output of rear system
Signal variable.
3, according to 3 testing procedures defined in maintenance function framework, order performs general security test program, defeated
Go out 6 kinds of data messages.
4, it is decoded computing according to 6 19 signal variables in step 2, exports 6 kinds of numbers of 19 LRU parts respectively
It is believed that breath, the different test results of 19 LRU parts of instruction.
Claims (1)
1. the parallel safety method of testing of LRU more than, for multiple identical LRU parts are carried out parallel security test,
It is characterized in that, the method comprises the following steps:
Step 1, the N road binary data signal of M LRU parts of Real-time Collection, after receiving test initiation command, according to LRU portion
Quantity M of part, encodes described data signal, generates the integer variable of N number of M figure place, and is stored in variable list；
Step 2, according to the security test requirement of LRU parts, is utilized respectively a logical operations same road signal to M LRU
State judges, generates the test result integer variable of N number of M figure place according to judged result；
Step 3, is decoded computing to each test result integer variable, exports the N drive test test result of each LRU parts respectively
