Abstract
The utility model discloses a virtual automobile gearbox testing diagnostic instrument which is characterized by comprising a vibration sensor, a signal conditioner, a PCI bus acquisition card and a computer; after acquires vibration signal, the vibration sensor sends the vibration signal to the signal conditioner; the signal conditioner processes the vibration signal, and converts the vibration signal into digital signal, and uploads the digital signal to the computer through the PCI bus acquisition card. The virtual automobile gearbox testing diagnostic instrument has the advantages of simple and convenient operation, low price, more professional diagnosis, higher diagnosis speed and more accurate diagnosis result.
Description
Technical field
The utility model belongs to test and field of analytic instrument, specifically, relates to a kind of subjunctive mood automotive gearbox testing and diagnosing instrument.
Background technology
Automotive transmission is the important assembly parts in the automotive system, and its rate of breakdown is also higher simultaneously.The gear, bearing and the axle that constitute variator are the working condition complexity, and along with its complicacy of raising of the performance of variator further improves, thereby it is increasing to cause that it is carried out the difficulty that accurate diagnosis analyzes.Traditional kinetic analyzer mainly carries out diagnostic analysis by hardware, lacks professional diagnostic function, and cost an arm and a leg, complicated operation.
The utility model content
The purpose of this utility model provides a kind of subjunctive mood automotive gearbox testing and diagnosing instrument, can overcome the deficiency of existing hardware instrument, diagnosis professional stronger, simple to operation, and price is also relatively more cheap.
For achieving the above object, the utility model is explained a kind of subjunctive mood automotive gearbox testing and diagnosing instrument, its key is: include vibration transducer, signal conditioner, pci bus capture card and computing machine, after described vibration transducer obtains vibration signal, vibration signal is passed to signal conditioner, signal conditioner is converted to digital signal after it is handled, and is uploaded to computing machine by the pci bus capture card.
Vibration transducer detects the vibration signal of measuring point on the automotive gearbox, and the signal that detects delivered to signal conditioner, signal conditioner to the signal that detects amplify, after filtering etc. handles, carry out the A/D conversion, at last with the digital signal that obtains, by the pci bus capture card, send into computing machine, when computing machine carries out the signal that obtains, analyses such as frequency-domain analysis and neural network, fuzzy diagnosis, expert system diagnosis, show test results or failure condition, realize automotive gearbox is tested and fault diagnosis fast and effectively.By the computer networking function, can also carry out remote testing.
Remarkable result of the present utility model is: a kind of subjunctive mood automotive gearbox testing and diagnosing instrument simple to operation, low-cost is provided, can overcome the deficiency of existing hardware instrument, carry out fault diagnosis by computing machine, that diagnoses is professional stronger, diagnosis speed is faster, diagnostic result is more accurate, simultaneously by computer networking, can also realize the remote testing of automotive gearbox.
Description of drawings
Fig. 1 is a functional-block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1: a kind of subjunctive mood automotive gearbox testing and diagnosing instrument, include vibration transducer 1, signal conditioner 2, pci bus capture card 3 and computing machine 4, after described vibration transducer 1 obtains vibration signal, vibration signal is passed to signal conditioner 2, after signal conditioner 2 is handled it, be converted to digital signal, be uploaded to computing machine 4 by pci bus capture card 3.
Described signal conditioner 2 is the PCI4472 capture card of NI company, this card provides the high-precision signal synchronous acquisition passage of 8 optional built-in ICP driving sources, 8 passages connect 8 vibration transducers 1, gather the vibration signal of 8 measuring points on the automotive gearbox simultaneously.
Its principle of work is as follows:
8 vibration transducers 1 detect the vibration signal of 8 measuring points on the automotive gearbox simultaneously, and the signal that detects delivered to signal conditioner 2, after the signal of 2 pairs of detections of signal conditioner amplifies, filtering etc. handled, carry out the A/D conversion, at last with the digital signal that obtains, by the pci bus capture card, send into computing machine 4, when the signal of 4 pairs of acquisitions of computing machine carries out, analysis such as frequency-domain analysis and neural network, fuzzy diagnosis, expert system diagnosis, show test results or failure condition, realize automotive gearbox is tested and fault diagnosis fast and effectively.
Computing machine 4 of the present utility model is analyzed and is adopted software to realize that this software section can be worked under the operating system platform of Windows98/2000/XP and later release.By the computer networking function, can also realize remote testing to automotive gearbox.As software section of the present utility model, allow it to break away from hardware components of the present utility model and carry out off-line analysis.
