Abstract

The invention discloses a device for monitoring abnormal noise of an automobile in real time. The device comprises a noise collecting module, a signal processing module, a main controller module, a warning promoting module, a remote network module and a fault judging and monitoring module. The data output end of the noise collecting module is connected with the data input end of the signal processing module and the data output end of the signal processing module is connected with the data output end of the main controller module. The data output end of the main controller module is connected with the data input ends of the noise collecting module and the warning promoting module. The data output end of the warning promoting module is connected with the data input end of the remote network module and the data output end of he remote network module is connected with the data input ends of the fault judging and monitoring module. By means of the device for monitoring abnormal noise of the automobile in real time, according to the detected abnormal vibration noise of parts such as an automobile engine and a gearbox, portions with faults of the automobile can be judged, thus a mobile phone information tip is given out, information is transmitted to a maintaining factory, and fault judging and prevention monitoring are carried out in real time.

Description

A kind of device of Real-Time Monitoring automobile abnormal sound

Technical field

The present invention relates to mechanics, acoustics, art of electronics, particularly relate to a kind of device of Real-Time Monitoring automobile abnormal sound.

Background technology

When et out of order, because mechanical vibration frequency is compared with normal circumstances with amplitude, there is relatively big difference, thereby can send abnormal vibrating noise in automobile, particularly particularly evident at the position of driving engine, change speed gear box and other power or the transmission device of automobile.At present, the judgement to vehicle failure position, the experience of mainly utilizing maintainer is made extremely by noise, but general chaufeur does not possess such ability.This kind of determination methods do not possess ageing and ubiquity, cannot allow chaufeur know timely and accurately vehicle et out of order.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of based on noise gathering device, signal processor and master controller, form there is whether et out of order of automatic decision, each major part of identification automobile, and can send warning signal in time and the device of a kind of Real-Time Monitoring automobile abnormal sound of failure condition.

The technical solution adopted in the present invention is: a kind of device of Real-Time Monitoring automobile abnormal sound, comprise noise gathering module, signal processing module, main controller module, alarm module, telecommunication network module and fault judgement and monitoring module, the data output end of noise gathering module connects the data input pin of signal processing module, the data output end of signal processing module connects the data input pin of main controller module, the data output end of main controller module connects the data input pin of noise gathering module and alarm module, the data output end of alarm module connects the data input pin of telecommunication network module, the data output end of telecommunication network module connects the data input pin of fault judgement and monitoring module.

Further, the noise sample that noise gathering device is collected carries out information process-, after formation electronic signal, is sent to master controller, and the preset standard frequency spectrum of master controller and producer compares, to judge automobile, whether there is parts et out of order, and make in time indication.

Further, if master controller is determined with parts et out of order, will send a signal to alarm module, thereby send short message prompt to car owner and maintenance producer, failure condition will be described.

The present invention has advantages of:

1. device is simple, installs easily.

2. complete function, monitoring in real time, failure judgement in time.

3. prepare location trouble unit.

Accompanying drawing explanation

Fig. 1 is block diagram of the present invention.

Fig. 2 is configuration schematic diagram of the present invention.

The specific embodiment

As shown in Figure 1, the device of a kind of Real-Time Monitoring automobile of the present invention abnormal sound, utilize noise gathering device to gather noisy samples, through information processing, by master controller, contrast noise information and preset standard frequency spectrum and analyze to judge whether et out of order of automobile component, thereby car owner and maintenance producer are sent to alarm message, and send failure message, realize Real-Time Monitoring.

As shown in Figure 2, described noise gathering module 2, is arranged on driving engine 6, change speed gear box 7 and drive disk assembly 8, refer to a kind of miniature geophone, by near the sound wave in receiving institute installation site more among a small circle, collect, the acoustic signals of record is passed to signal processing module 3.

Described signal processing module 3, refers to a kind of sound-electric transfer device being comprised of electret and close-up crystal unit, by electret, receives acoustic signals, be converted into vibrations form, cause volume change, by close-up crystal unit, be converted into electric signal, thereby complete the conversion to electronic signal by acoustic signals.

Described main controller module 4, refer to that the noise electronic signal standard frequency spectrum default with keeping in repair producer to transporting compares, if in the deviation range that this signal allows at default standard frequency spectrum, illustrate that automobile component does not have et out of order, to send signal to noise gathering module 2, continue to gather noise; If this signal has departed from the permissible variation scope of default standard frequency spectrum, automobile component et out of order is described, will send a signal to alarm module 5.

Described alarm module 5, refers to a kind of simple and easy information transmitting apparatus that SIM is housed, and when it receives after failure message, by SIM, from trend car owner and maintenance producer 10, sends failure message, makes prompting and reports.

Described driving engine 6, thus refer to and a kind ofly in machine intimate burns gasoline, produce heat energy, and heat energy is converted into mechanical energy, is the device of providing power for motor.

Described change speed gear box 7, refers to a kind of engagement that changes different large miniature gearss, makes motor vehicle speed and moment of torsion produce the device of different variations.

Described drive disk assembly 8, refers to a kind of device that changes the torque of engine output, comprises power-transfer clutch, change-speed box, speed-change and gearshift joystick, wheel carrier, tween drive shaft etc.

The judgement of described fault and monitoring module 9, refer to 10 configurations of maintenance producer to the monitoring of automobile component fault and analytical equipment, it,, by the note failure report receiving, records and analyzes it, thereby realizes the real-time monitoring to vehicle.

Described maintenance producer 10, refers to reception failure report, and vehicle is monitored in real time, the maintenance station of the fault of being responsible for servicing a car.

Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
