Description
Technical field
The utility model relates to a kind of open-short circuit device automatically, particularly relates to a kind of automatic open-short circuit device based on raspberry group.
Background technology
At present, open-short circuit realizes mainly through manual test, ICT or other meter specially.But all there are some defects in these method of testings.Such as manual test, with multimeter bit by bit manual measurement in circuit, original and inefficiency, is only suitable for test on a small scale; ICT (InCircuitTester) i.e. In-circiut tester is the automated test device of a kind of PCBA, and apparatus expensive, can realize the open-short circuit of PCBA or other circuit; Meter specially refers to test specific circuit device, such as wire test instrument, is generally used for testing winding displacement or other has the cable of the relation of being fixedly connected with.When needs customize fairly large testing requirement, manual test is obviously wasted time and energy, and does not possess operability.Though ICT can realize extensive batch testing, but ICT device hardware cost, and the testing software cost of required exploitation in early stage is all very high.Meter specially generally can only test specific circuit, very flexible, and test channel number is limited, is also not too applicable to large scale test.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of automatic open-short circuit device based on raspberry group of new structure, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of automatic open-short circuit device based on raspberry group.
The technical solution of the utility model is as follows:
A kind of automatic open-short circuit device based on raspberry group, it is characterized in that: comprise raspberry group, range handover module, analog to digital converter, multiple analog switch array, power management module, described raspberry group connects described range handover module, analog to digital converter, multiple analog switch array.
Further, the connected mode of described multiple analog switch array is series connection.
Further, described raspberry group includes HEMI interface, USB interface, GPIO interface, spi bus.
Further, described raspberry group is connected with analog to digital converter with described analog switch array respectively by spi bus.
Further, described raspberry group connects described range handover module by GPIO interface.
Further, described power management module connects described raspberry group, range handover module, analog to digital converter, analog switch array respectively.
Further, the input voltage of described power module is 12V, and output voltage can be 12V, 5V and 3.3V.
By such scheme, the utility model at least has the following advantages:
The utility model is based on a kind of card form computer---and raspberry is sent (RaspberryPi), can realize the test automatically of extensive batch, and with low cost, and test high efficient and reliable is easy to maintenance.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, a kind of automatic open-short circuit device based on raspberry group described in the utility model one preferred embodiment, comprise raspberry group, range handover module, analog to digital converter, multiple analog switch array (only drawing in figure), power management module, wherein raspberry group connects described range handover module, analog to digital converter, multiple analog switch array, and multiple analog switch array connects in the mode of series connection.Raspberry group in the utility model includes HEMI interface, USB interface, GPIO interface, spi bus, wherein raspberry group is connected with analog to digital converter with described analog switch array respectively by spi bus, and raspberry group connects described range handover module by GPIO interface.Power management module connects described raspberry group, range handover module, analog to digital converter, analog switch array respectively, and the input voltage of power module is 12V, and output voltage can be 12V, 5V and 3.3V.
Principle of work of the present utility model is as follows: power module output voltage, the range of adjustment range handover module, according to certain sequence, or the input channel of any combination of two analog switch array, by the resistance value between survey calculation passage, can judge whether open short circuit between passage.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
