Background technology
In recent years, with the raising of automated manufacturing level, numerically-controlled machine tool is widely applied in production scene, because of numerical control
Lathe is to integrate mechanical, electrical, liquid equipment, and precision is high, the degree of automation is advanced, and great difficulty is brought to repair, therefore
Barrier Diagnostic Time will obviously be grown compared with machine tool.The fault diagnosis of numerically-controlled machine tool always is the hot spot of research, although numerical control
Lathe itself also provides the information of fault diagnosis, but the use of these information is suitable for a skilled maintenance personal, and right
Still seem extremely difficult in general maintenance personal.In addition, current intelligentized diagnosing faults of numerical control machine method comparative maturity,
But some achievements are difficult to be converted to product, are reduced using frequency because too expensive having this Intelligence Diagnosis product
It is secondary.
Invention content
The present invention is directed to overcome the deficiencies of existing technologies, a kind of diagnosing faults of numerical control machine device is provided, can be judged rapidly
The position that failure occurs, or early warning is carried out to failure.
In order to solve the above-mentioned technical problem, the invention is realized in this way：
A kind of diagnosing faults of numerical control machine device, it is characterised in that：It includes sensor, signal pickup circuit, processing unit, report
Alert device, LED light, LCD display, driving circuit and the button that running parameter is set；
The sensor is mounted on numerically-controlled machine tool, and signal pickup circuit handles the signal that sensor detects, is formed
Standard signal input processing unit, processing unit compare the signal of input with characteristic value, and the numerical value beyond setting can lead to
Alarm and LED light alert are crossed, while being shown information on an lcd display by driving circuit.
The diagnosing faults of numerical control machine device, it is characterised in that：The processing unit is microcontroller.
The diagnosing faults of numerical control machine device, it is characterised in that：The characteristic value includes switching value, analog quantity, frequency
Rate signal and vibration signal, switching value can be used after taking out filtering by photoelectrical coupler, and analog signal and frequency signal are used
Integrated operational amplifier picks up, and is taken out signal using wavelet algorithm or EMD algorithms.
The diagnosing faults of numerical control machine device, it is characterised in that：The diagnostic device uses BP algorithm.
The beneficial effects of the invention are as follows：It is intelligentized design, there is learning functionality, existing normal working condition is carried out
Study, then can monitor lathe working condition, and show to lathe working condition, and failure when can be reported
It is alert, it is suitble to the enterprise more than numerically-controlled machine tool quantity, a large amount of maintenance time can be saved, it is small, it is easy to use, can be faster
Failure is positioned, just with popularization.
Description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
As shown in Figure 1：A kind of diagnosing faults of numerical control machine device, it includes sensor, signal pickup circuit, processing list
Member, alarm, LED light, LCD display, driving circuit and the button 8 that running parameter is set；
Sensor is mounted on numerically-controlled machine tool 1, and signal pickup circuit 2 handles the signal that sensor detects, forms mark
Calibration signal input processing unit, processing unit 3 compare the signal of input with characteristic value, and the numerical value beyond setting can pass through
5 alert of alarm 4 and LED light, while being shown on LCD display 6 information by driving circuit 7；Institute
It is STC microcontrollers to state processing unit.
Trouble-shooter is connected with numerically-controlled machine tool, some signal acquisition points are provided on numerically-controlled machine tool, these acquisitions
In the information input to diagnostic device of point, diagnostic device carries out discrimination to these information, and exports diagnosis.Numerically-controlled machine tool exists
When operation, trouble-shooter is also being run, and belongs to on-line real time monitoring.Processing method of the diagnostic device to fault message
It is：Each state parameter of lathe is detected, and compared with characteristic parameter, if exceeding error, alarm can be sent out
Information, meanwhile, device software uses BP neural network algorithm, and algorithm would conclude that whether failure is sent out according to the information of input
Raw and happening part.Structural framing figure is as shown in Figure 1.
Signal pickup circuit is realized：
Various types of signal is various in numerically-controlled machine tool, it is impossible to be detected one by one, usually by analysis, selection most can representing fault
The characteristic value of type, these characteristic values include on-off model, analog signals, frequency signal, vibration signal etc..For switch
Amount can be used after taking out filtering by photoelectrical coupler, for analog signal and frequency signal, mainly be amplified with integrated computation
Device picks up, and is taken out signal using certain algorithm.Common algorithm such as wavelet algorithm, EMD algorithms etc..
The realization of processing unit：
In hardware design, hardware cost is considered, the function of the division software and hardware of science is needed to realize.Intelligent chip uses mesh
The microcontroller of preceding common STC series, these microcontrollers it is cheap, and design requirement can be met.
BP network diagnosis malfunctioning modules divide：
For more accurately diagnosis, by the failure modes of numerically-controlled machine tool, servo segment BP network failure sort modules are divided into,
The parts CNC BP network failure sort modules, mechanical part BP network failure sort modules etc., in addition, because BP network trainings need
The time wanted is long, causes sluggishness, so, it takes and first trains network, then by input layer, the connection of hidden layer, output layer
Weight is preserved in the microprocessor in a manner of array, is realized using look-up method when calculating, and algorithm calculating is substantially reduced
Time meets inline diagnosis.
