Description
Art
The present invention relates to a kind of detonator electrical parameter comprehensive tester, suitable for field of detecting.
Background technology
Commercial electric detonator is widely used initiating equipment in engineering explosion, and the good and bad degree of its electrical property and detonation are reliable
Property it is closely related with safety in utilization, before product export and explosive applications before have to pass through strict service check certification, because
This, the advance of the tester for detecting detonator items electrical property, test accuracy and reliability are most important.
During detonator production, detonator resistance sorting instrument is a kind of essential instrument, is welded for bridge wire resistance
The processes such as conducting, finished product detonator impedance inspection.The quality of detonator resistance sorting instrument performance, not only influences product quality, more shadow
Ring the safety in production of detonator.
A few days ago, the quick-fried corporate boss of the people will use LDC-I types Cap resistance meter, WYS-1 type detonator delay times to survey
Try the DC9801 type intelligence detonator electric parameters testings that instrument, WLD-1 type detonator electric parameter testers and Institutes Of Technology Of Nanjing develop
Instrument, these instruments earlier than《Industrial electro cosmos pipe》T GB8031-2005) design and develop before standard revision, partial test function oneself not
The detonator performance test requirement of standard revision can be met.Newly-designed detonator electric parameter tester herein, expires in method of testing
On the basis of sufficient revised standard new demand, electric cap items electrical parameter integration test function is also equipped with, the spy for possessing a tractor serves several purposes
Point, avoiding the examination and test of products and demolition site test detonator performance needs to carry the trouble of more instrument.
The content of the invention
The present invention provides a kind of detonator electrical parameter comprehensive tester, and the instrument has that stable performance, test data are accurate, passes
The features such as sensor is easy for installation.Circuit structure is compact, small volume, working stability, and adaptability is good, and has good anti-interference
And reliability.
The technical solution adopted in the present invention is.
Detonator electrical parameter comprehensive tester is amplified by accurate quick-fried, the detonator delay time test circuit of series connection, communicating circuit, signal
Modulate circuit forms.
Accurate quick-fried, the detonator delay time test circuit of series connection by transformer, voltage multiplying rectifier bridge, high-power FET,
The composition high-voltage output circuits such as FET detection circuit.After upper electricity, transformer is filled by voltage multiplying rectifier bridge to capacitance group CZ3
Electricity.When have selected the accurate quick-fried option of series connection, after switch is blown out, single-chip microcomputer P6.7 pins export high level signal CLZB.CLZB is high
Level signal is that low level makes VEE be turned on VE1 by optocoupler G3 by NOT gate U3C saltus steps, and MKG conductings, electric capacity CZ3 passes through electricity
Road detonating capsule.To remove the accurate of external interference and testing time, it is low electricity that single-chip microcomputer, which receives one by high level saltus step,
It is flat.Handled by program, single-chip microcomputer P6.6 pins output low level, start timing test and delay the time.
The resistance capacitance group that the communicating circuit is mainly matched by U8 (MAX485E), U5 (MAX232) and its periphery
Into.Main frame inquires about each slave by way of serial communication, so as to obtain the extension time of each hair detonator.Due to using series connection
The mode of communication so that on line is few, does not interfere with, and successfully tested rate is high.U5 (MAX232) is that preparation is used as the machine and computer expert
The interface chip of news.
The signal amplifying and conditioning circuit only does one-level amplification to signal using AD620, is the power module by front end
The voltage-stabilized power supply of offer.In addition, the interference that the faint differential voltage signal of electric bridge output may carry some high frequencies is believed, therefore
The low pass R-C web filter circuits being made up of R4, R5, C1, C2 are devised, signal is first carried out simple low pass filtered through this circuit
Ripple, then enter back into instrument amplifier and be amplified.
The beneficial effects of the invention are as follows：It is accurate with stable performance, test data, the features such as sensor is easy for installation.Electricity
Line structure is compact, small volume, working stability, and adaptability is good, and has good anti-interference and reliability.
Brief description of the drawings
