The utility model purpose is to overcome above-mentioned shortcoming, removes complicated change-over circuit, proposes a kind of simple in structure, volume is little, weight is lighter, easy to operate computer controlled automobile reometer detector.
The utility model purpose is realized by following technical scheme: computer controlled automobile reometer detector, its structure includes the test board that metal material is formed, precision resistor, total power switch, current and power supply switch, current selected switch, reset button, computer treating apparatus, D.C. regulated power supply, computer D.C. regulated power supply and check-out console, precision resistor, total power switch, current and power supply switch, current selected switch, reset button and computer treating apparatus are installed on the testing stand.D.C. regulated power supply, computer D.C. regulated power supply are installed in test board.D.C. regulated power supply, computer D.C. regulated power supply, direct-flow current regulator, current polarity converter and check-out console are installed in test board, the current value modular converter is installed on the check-out console, ± 15 volts of D.C. regulated power supply outputs, the input end of connection current value modular converter ± 15 volts.The current aperture that the positive output termination current controller of direct-flow current regulator, the other end of current controller pass the current value modular converter turns back to the negative terminal of direct-flow current regulator, forms a current return.Tested reometer also is connected on the current controller.The output terminal of current value modular converter inserts the computer treating apparatus, and the computer treating apparatus connects digital display screen, with the numerical signal input digit display screen demonstration of result.
Being contained in the preceding pilot lamp of testing stand all is connected with the computer output terminal respectively with sounder.If the error amount of tested table surpasses setting, then the computer treating apparatus to pilot lamp and sounder, sends sound, light with signal conveys, simultaneously alerting signal.D.C. regulated power supply and computer D.C. regulated power supply can be selected integrated direct supply or linearization D.C. regulated power supply for use, or the switch DC stabilized voltage supply, or the self-control D.C. regulated power supply.
The utility model has the advantages that and detect the degree of accuracy height, stable performance, data are reliable, alleviated weight, and are simple in structure, simplified circuit greatly, and components and parts have been bought easily, and it is convenient to install, debug, and cost is lower, and is easy to utilize.Because adopted the standard value numeral to show, thereby ocular and clear, artificial parallax avoided; The measurement range of this computer controlled automobile reometer detector can be easy to the different ranges of tested table change, thereby highly versatile.
As an embodiment, its work reason and testing process is described in conjunction with the accompanying drawings.
Fig. 1 is the front elevation of computer controlled automobile reometer detector.
Fig. 2 is the cut-away view that computer controlled automobile reometer detector removes bonnet.
Fig. 3 is a computer controlled automobile reometer detector vertical view.
Fig. 4 is the fundamental diagram of computer controlled automobile reometer detector.
This computer controlled automobile reometer detector has a test board (1) that constitutes with metal material, is equipped with on the face of test board (1) and moves the precision resistor WXD3-13 (4) and the reset button (6) of drawing among total power switch HY2-15 (10), current and power supply switch HY2-15 (11) and the direct-flow current regulator JWL-30I (7).Computer treating apparatus HY-51A (15), it comprises digital display screen (16), keyboard (17) and microwriter TP μ P (18), D.C. regulated power supply 4NICC78 (9) and computer D.C. regulated power supply 4NICC78 (12) is installed in test board, and it is can guarantee to supply with galvanic current to press that these two stabilized voltage supplys can be selected the various types of D.C. regulated power supplies or the effect of self-control D.C. regulated power supply that meet the demands for use.In test board, check-out console (8) also is housed, current value modular converter KT30A/P (13) is housed on it, D.C. regulated power supply (9) output terminal ± 15 volts connects the input end of current value modular converters (13) ± 15 volt, the output terminal of current value modular converter (13) inserts computer treating apparatus (15), with the signal input digit display screen (16) after handling.The computer treating apparatus also comprises keyboard (17) and mini-printer (18).
During work, earlier tested automobile-used reometer A is inserted, open total power switch (10), firing current source switch (11) again, D.C. regulated power supply this moment (9) ± 15 volts of voltages of output (E1) supply is installed in the current value modular converter (13) on the check-out console (8).The anodal output current of while direct-flow current regulator (7), flow into the anode of tested reometer A through one side of current controller SRC3631-5-1-N (20), flow through the another side of current controller (20) by the negative terminal of tested reometer, return the negative pole of direct-flow current regulator (7) by the current aperture of current value modular converter (13).Electric current is walked around after the output of die change piece (13) sends into computer treating apparatus (15) and handle, and promptly goes up the standard value of display application at digital display screen (16).Regulate precision resistor (4), can change the current value of the tested power meter of flowing through, the indicating value of tested reometer and the difference of standard value are the error of this reometer.If this error amount surpasses setting, then the computer treating apparatus is sent this signal into pilot lamp (2) and sounder (3), sends sound, light alerting signal simultaneously.The power supply of computer treating apparatus (15) is supplied with in the time will surveying the inverse current value with D.C. regulated power supply (12) by computer, can dial selector switch (5) to "-" limit, this moment is under the effect of current controller (20), make the electric current that flows out by the positive pole of direct-flow current regulator (7) enter reometer through the negative terminal of tested reometer earlier, the another side that flows out to current controller (20) by its anode is delivered to the current aperture of current value modular converter (13) and is returned, to the negative pole of direct-flow current regulator (7).Like this, the current value of the automobile-used tested reometer A that flows through is reverse equivalence, and therefore, reometer A pointer is checked its negative sense precision to negative direction deflection.
