Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, man-made diamond pressing machine splits hammer real-time monitoring device, is installed on the detection components 1 on 6 diamond press Top hammer steel rings 2 including main frame, one_to_one corresponding, the connecting line of connect one to one main frame and 6 detection components 1, connects the control line of main frame and press switch board.
As in figure 2 it is shown, described detection components 1 is made up of the vibrating sensor (such as BMA180) being sequentially connected with, detection components processor (such as PIC18F45K50), the first telecommunication circuit.As shown in Figure 3, described main frame includes 6 second communication circuit and a host-processor (such as PIC18F46K80), described second communication circuit on one side and the first telecommunication circuit connect, one end is connected on host-processor, and described host-processor is connected to press switch board by control line.As shown in Figure 4, described main frame includes 6 communications components and a PC (such as association T4900DI5-3470), and one end of described communications component is connected with the first communication chip, one end is connected on PC, and described PC is connected to press switch board by control line.
Further, described main frame includes display (such as association L1710A), and described host-processor or PC are connected with monitor signal.
In diamond press production process, the vibrating sensor in detection components constantly detects the vibration of top hammer, in real time its vibration information is sent to detection components processor, or is sent to main frame by detection components again.Processor (the detection components processor in detection components, the processor in main frame or PC) according to splitting the amplitude of hammer vibration, specific period, specific persistent period and signal envelope determine whether there is and split hammer and occur.
Flow process 1.Undertaken splitting hammer by the processor in detection components to judge, then, processing result information (that is, " certain top hammer has split hammer " information or " splitting hammer not occur " information) is sent to main frame by this processor.
Flow process 2.Undertaken splitting hammer by the processor in main frame or PC to judge, so, top hammer vibration information (not judging) is sent to main frame by the processor being accomplished by detection components, main frame self produce " certain top hammer has split hammer " information or " splitting hammer not occur " information.

The present embodiment to split hammer determination methods specific as follows: processor (processor in detection components, the processor in main frame or PC) according to splitting the amplitude of hammer vibration, specific period, specific persistent period and signal envelope determine whether there is and split hammer and occur.
First, as it is shown in figure 5, compared with the interference of production scene, the amplitude splitting hammer vibration signal is very big.The interference of production scene is generally the sound transmitted from press surrounding, and these acoustical signals are converted to vibration in top hammer, its signal amplitude only small (compared to splitting hammer vibration signal).Therefore, actual measurement can be adopted to split the 50%-70% of hammer vibration signal amplitude as the threshold value splitting hammer vibration signal detection.
The second, the signal period has repeatability, namely for the top hammer of same model, split hammer the signal period there is concordance.Such as, surveying certain top hammer and split hammer signal, its cycle is about 104uS, as shown in Figure 6.
3rd, split hammer the vibration signal persistent period be 8-20mS.In Fig. 7, the time difference between two vertical graticules is about 10mS.

If processor detects the signal meeting above four features simultaneously, can be judged to that splitting hammer occurs.
The system splitting hammer determination methods corresponding is shown in Fig. 8.Signal from vibrating sensor enters band filter, and the parameter of this band filter is: 1, low-frequency cut-off frequency is 8KHz；2, high-frequency cut-off frequency is 12.5KHz；3, attenuation outside a channel is every octave-40dB.(explaining: this filter centre frequency is 10KHz, and bandwidth is 4.5KHz, it is possible to what ensure all model top hammers splits hammer signal by this wave filter).The output signal of band filter is connected respectively to frequency analysis module and envelope analysis module.In frequency analysis module, use correlation operator carry out frequency coupling, when input signal frequency identical with the frequency presetting signal or close to time, correlation operator output frequency matched signal.Envelope analysis module adopts numerical analysis method, it is possible to calculate amplitude and the envelope persistent period of signal.
The steel loop that the sensor vibrated for collection machinery is arranged on top hammer (is tightly fastened between top hammer and steel loop by the present embodiment, it is that actual solid connects), so when certain top hammer splits hammer, the mechanical vibration that its sensor senses are eager to excel a lot than the mechanical vibration that the sensor of other top hammers (including the top hammer on other press) senses.By vibration signal and given threshold value being compared, only vibration signal exceedes and its is possible under threshold value situation be judged to that splitting hammer occurs, and thus avoids the erroneous judgement caused by interference.In the screening plus other three kinds of signal characteristics, False Rate can be less.
At present, if splitting hammer in production process, producers first have to judge manually to split the position of hammer, waste time and energy.And for this detecting device, when splitting hammer, can determine that be which tup there occurs split hammer and show over the display.So, producers can save the time and quick-replaceable of splitting manually detection after hammer occurs, improves production efficiency.
