Description
Technical field
The utility model relates to the technical field of board test, is a kind of automatic testing equipment of LBE bus board specifically.
Background technology
Along with the high speed development of mechanical automation, automation equipment more and more comes into one's own in a lot of field and relies on.Wherein test particularly outstanding at commercial product and industrial products, and the product turnout amount of these industry production is larger, and the product of each major company will have the strict index of quality in sale to during market, for recognizing the index whether product reaches required, just needs a large amount of test jobs.And early stage testing tool major part is all manual operation, so complete a large amount of manpower of product test need of work and time guarantee, this just requires company to have very large tester to drop into and the sufficient time ensures, but because people goes the unwarrantable energy high concentration of repeatable operation testing tool, just likely occur the problems such as the inaccurate or test leakage examination of index, such production efficiency and product quality just can not get fine guarantee.Nowadays adopt automated machine test in each major company, adopt processor to carry out index monitoring and would not occur due to the problems referred to above, just well solve fund, time and quality problems.The automatic test of current LBE bus board does not also have solution.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of automatic testing equipment of LBE bus board.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
The automatic testing equipment of LBE bus board of the present utility model, comprising: LBE mainboard groove, the tested groove of LBE, serial port drive circuit and programmable logic device (PLD); Wherein LBE mainboard groove is connected with the tested groove of LBE, and the tested groove of LBE is connected with serial port drive circuit, and serial port drive circuit is connected with programmable logic device (PLD), and programmable logic device (PLD) is connected with LBE mainboard groove.
The utility model also can adopt following technical measures:
In described LBE mainboard groove, standard LBE motherboard is set, standard LBE motherboard arranges display unit.
The chip model of described programmable logic device (PLD) is EP3C5F256.
The chip model that described serial port drive circuit adopts is SP485EEN.
The advantage that the utility model has and good effect are:
The automatic testing equipment of LBE bus board of the present utility model, have employed programmable logic device (PLD), ensure that the flexible of base plate and robotization, the automatic test of LBE bus board can be realized, and it is simple to have structure, reliable operation, the features such as applicability is strong and easy to operate.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the automatic testing equipment of LBE bus board of the present utility model.
Embodiment
Referring to drawings and Examples, the utility model is described in detail.
Fig. 1 is the schematic diagram of the automatic testing equipment of LBE bus board of the present utility model.
The automatic testing equipment of LBE bus board of the present utility model, comprises LBE mainboard groove, the tested groove of LBE, serial port drive circuit and programmable logic device (PLD); Described LBE mainboard groove is connected with the tested groove of LBE, and the tested groove of LBE is connected with serial port drive circuit, and serial port drive circuit is connected with programmable logic device (PLD), and programmable logic device (PLD) is connected with LBE mainboard groove.
LBE mainboard groove in the utility model is for accessing the standard LBE motherboard of LBE interface, and user can issue at motherboard coding the data and duty that data control equipment work and treatment facility send.
In LBE mainboard groove, standard LBE motherboard is set, standard LBE motherboard arranges display unit.Display unit can be the display screen be connected with standard LBE motherboard.
The chip model of programmable logic device (PLD) is the EP3C5F256 of ALTERA company.
The chip model that described serial port drive circuit adopts is the SP485EEN of SIPEX company.
The tested groove of LBE in the utility model is for accessing the device board of LBE interface, i.e. tested LBE board, the rate control command that reception mainboard issues also performs, the data obtained after execution, and data result is sent to serial port drive circuit.
The execution data result that serial port drive circuit in the utility model sends for receiving the tested groove of LBE, and data result is carried out level conversion, re-send to programmable logic device (PLD).
The execution result that programmable logic device (PLD) in the utility model transmits for receiving serial port drive circuit, and result is carried out comparing and analysis, then comparison and analysis result are sent to LBE mainboard groove, show test results.
Principle of work of the present utility model and process are: first, tested LBE board is inserted in the tested groove of LBE, simultaneously corresponding standard LBE motherboard is inserted in LBE mainboard groove, the all data targets of tested LBE board are written in programmable logic device (PLD), standard LBE motherboard issues test instruction and data, tested LBE board receives instruction and data, start the test carrying out relevant item, and obtain test data, the test data of tested LBE board carries out level conversion through serial port drive circuit again, convert the level form that programmable logic device (PLD) connects to, after programmable logic device (PLD) receives test data, first serial data is converted to parallel data, data target corresponding with standard LBE board is again compared, draw comparison result, again by comparison result, be sent in LBE mainboard groove, motherboard in LBE mainboard groove, to show test results.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model with preferred embodiment openly as above, but, and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
