Description
Technical field
The utility model relates to a kind of vibration tachometer.
Background technology
By vibration tachometer, can solve and how quick tachometric survey in the situation such as vehicle idling, high speed is otherwise back to the numerous difficult problems of PC.Use vibration tachometer, more directly the vehicle condition of vehicle is shown, input again in PC without the need to manual record.
Utility model content
The purpose of this utility model is to provide a kind of vibration tachometer, and it can solve above-mentioned shortcoming of the prior art.
The utility model is by the following technical solutions:
A kind of vibration tachometer, comprise a shell, and described shell is provided with a LCDs, and described display screen inside is provided with a control panel, and described chain of command is electrically connected control one LCDs and a cylinder number arranges key, and described LCDs and described cylinder number arrange key is located on described shell, and the side of described shell is provided with a power switch, a power interface, a RS232 interface.
Described shell is also provided with an interface, and this interface is electrically connected described control panel, and described interface can connect exhaust analyzer or smokemetor.
Described shell is also provided with a vibration-testing line interface, and described vibration-testing line interface and described control panel are electrically connected.
The utility model has the advantages that:
1, easy to use portable: simple operation, the little quality of volume is light, greatly reduces manpower and materials.
2, applicability is strong: the engine speed test that can be used in various, has adaptivity, the vehicle detection of the different cylinder of energy Auto-matching.
3, measure accurately: there is powerful data processing function, carry out multi collect, computing gained by ARM in conjunction with DSP.
Accompanying drawing explanation
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail, wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit diagram of exhaust analyzer of the present utility model.
Fig. 3 is the circuit diagram of control panel of the present utility model.
Embodiment
Embodiment of the present utility model is set forth further below in conjunction with accompanying drawing:
As shown in Figures 1 to 3, a kind of vibration tachometer, comprise a shell, and described shell is provided with a LCDs 4, and described display screen inside is provided with a control panel, and described chain of command is electrically connected control one LCDs and a cylinder number arranges key 2, and described LCDs and described cylinder number arrange key is located on described shell, and the side of described shell is provided with power switch 1, power interface 5, RS232 interface 6, pilot lamp 3.
Described shell is also provided with an interface 7, this interface is electrically connected described control panel, and described interface can connect exhaust analyzer or smokemetor.
Described shell is also provided with a vibration-testing line interface 8, and described vibration-testing line interface and described control panel are electrically connected.
Using method of the present utility model is:
When just powering on, LED light Chang Liang, display screen display C-04, is expressed as four cylinder cars, and after about 3 seconds, LED starts flicker, and display screen display rotary speed data, represents that mainboard enters normal operating conditions.
After rotational speed meters enters normal operating conditions, if measuring head has been adsorbed on automobile, display has been shown as automobile rotational speed, if measuring head is completely static, display is shown as 0 (because there being microvibration during hand-held measuring head, display also can show a less numerical value).When rotational speed meters normally works, if push button, then display display C-04, after time delay about 3 seconds, recovers display tachometer value.
Automobile rotational speed exports with different data modes by square wave output interface and RS232 interface.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
