Therefore, the terminal module proving installation that uses the utility model embodiment to be provided is tested terminal module, whether the tested module of judging that not only can robotization exists fault, can also realize concrete fault is accurately located (specific to which pin, output/input direction), help reparation to the fault terminal module.
Below the flow process of using above-mentioned terminal module proving installation that terminal module is tested is specifically described, with the workflow of the terminal module proving installation of more specific description present embodiment:
Fig. 3 is the connection diagram of the tested interface of terminal module proving installation shown in Figure 2 among the utility model embodiment and tested terminal module, as shown,
Usually, the keyboard interface of terminal module, LCD interface and other control interface all use general I/O (the General-Purpose Input/Output of CPU (or other signal processing unit), be called for short GPIO) the pin realization, its I/O characteristic is determined by software arrangements according to concrete the application.For convenience of description, below keyboard interface, LCD interface and other control interface that the GPIO pin of the CPU by this module in the terminal module (or other signal processing unit) is realized be referred to as interface.As shown in Figure 3, start after the tested terminal module, as follows to the concrete testing procedure of each interface:
When needing the input characteristics of test interface 301, cycle tests generation unit 101 generates cycle testss, and is general, the GPIO pin of interface correspondence may exist level normal high, often low, open circuit, this pin and faults such as other pin faults link to each other.Can adopt following method of testing:
Each GPIO pin of interface unit 106 correspondences is corresponding respectively with each GPIO pin of tested interface 301, input test unit 101 is by interface unit 106, to tested interface 301 input test sequences, at this moment, everybody of cycle tests is corresponding with each GPIO pin of tested interface 301 respectively, and the figure place of cycle tests equals the GPIO number of pins of tested interface 301.For convenient test, the result understands, the cycle tests that can make this input be have only one with other every value cycle testss inequality.Such as: 01111...11,10111...11,111101...11,1000...00,01000...00,000100...00 etc., use with other value different value be 0 cycle tests, can detect the GPIO pin of normal high fault, use with other value the value of different position be 1 cycle tests, can detect the GPIO pin that often hangs down fault.
For the normal low fault of the incoming level of the GPIO pin that detects tested interface 301, tested interface 301 GP configuring IO, the read test sequence, judging unit 104 judges that cycle tests that tested interface 301 reads is whether consistent with the cycle tests that input test unit 101 is imported to this tested interface 301 by interface unit 106, if it is inconsistent, there is fault in input direction with this corresponding GPIO pin in not corresponding to position on the then tested interface 301, such as: the input test unit to the cycle tests of tested interface 301 inputs is: 011111111, the cycle tests that tested interface 301 reads is: 011111110, can judge that then there is fault in the input direction of the GPIO pin of the 9th correspondence.
Use above method, make that successively value is that 0 position is respectively everybody in the cycle tests, go through, just can detect the GPIO pin that there is fault in input direction all over all.Here, if the GPIO number of pins of this tested interface is N, then need to carry out N test.
For the normal high fault test of the incoming level that detects the GPIO pin, in like manner, use above method, make that with this value is that the position of 1 (other value is 0) is respectively every in the cycle tests, go through all over all positions, just can detect the GPIO pin that there is fault in input direction.
When needs are tested the output characteristics of tested interface 301, the cycle tests that output test cell 102 notifies tested interface 301 outputs to determine by interface unit 106, usually, in like manner in the test of top output characteristics, output test cell 102 can require the cycle tests of these tested interface 301 outputs be have only one with other every value cycle testss inequality.Require successively respectively in the cycle tests of these tested interface 301 outputs with other value different position be respectively 0,1, and make this in other value the position of different value be respectively positions different in the cycle tests, go through all over behind all positions, use this cycle tests, can detect GPIO pin often low, normal high fault.
Tested interface 301 is according to the notice of output test cell 102, GP configuring IO pin, the output cycle tests, data-reading unit 103 is by interface unit 106, read the cycle tests that tested interface 301 is exported, whether consistent by the cycle tests that judging unit 104 judgment data reading units 103 cycle tests that reads and the interface of exporting test cell 102 notice terminal modules are exported, if it is consistent, the outbound course non-fault of this tested interface then, otherwise there is fault in the input direction with this corresponding GPIO pin in not corresponding to position on the tested interface 301, such as: output test cell 102 notifies the cycle tests of tested interface 301 inputs to be: 011111111, the cycle tests of tested interface that data-reading unit 103 reads 301 outputs is: 0111111101, then can judge the 8th correspondence the GPIO pin have a normal low fault of output level; Perhaps, output test cell 102 notifies the cycle tests of tested interface 301 inputs to be: 100000000, the cycle tests of tested interface that data-reading unit 103 reads 301 outputs is: 100010000, then can judge the 5th correspondence the GPIO pin have a normal high fault of output level.
Therefore, for the tested interface 301 that has N GPIO pin, finish the input of all GPIO pins of this interface, the fault test of outbound course, need carry out 4N and survey test.
More than a kind of terminal module proving installation that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment just is used to help to understand the structural principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment principle, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
