Detailed description of the invention
The concrete scheme of the present invention is described below in conjunction with the accompanying drawings.
See Fig. 1, it is shown that the measuring principle figure of anti-static clothing online testing device of the present invention, its
Test to as if human body accesses electrode and antistatic clothing accesses the resistance between electrode, specifically include, human body
Access electrode, antistatic clothing accesses electrode, (such as, uses list by electric bridge comparison circuit with controller
Sheet machine) connect, controller is also connected with measurement result instruction device and has connecing of correspondence with foreign country and control
Mouthful.
Wherein, human body accesses the metallic conductor that electrode is a finger pressing, connects into measurement by wire
In the middle of circuit.It is connected with the protecting field wire of building to the reference of this test device and realizes isoelectric level, as
Really human body is with electrostatic charge, then test start can release quickly through bleeder resistance, thus may be used
To place electrostatic leakage ball again outside noting be used in antistatic region.
The access electrode of described antistatic clothing, preferably electrode use conductive fabric or conductive rubber etc. to have
Certain elastic material, and ensure certain contact area, reached by arm pressing electrode when test
The function accessing test circuit to antistatic clothing.In another preferred scheme, access electrode and use metal
Fixture, the form of metal fixture can be various, and preferably by the mouth of flat, contact area is not less than
25.5mm*51mm, contact surface uses the flexible material such as conductive fabric or conductive rubber.
Test device preferably employs the serial bus interface of RS485, and they can be one or multiple devices
Connect into a network with computer, by telecommunication circuit, measurement result is transmitted out to computer or electricity
Subset, client or high in the clouds, conveniently record and manage or form more complicated system.
External equipment can be controlled by this interface by controller according to measurement result, such as can root
The most qualified according to measurement result, the switch of access control etc. realizes the intelligent access control system of antistatic working area.
The explanation present invention tests the operation principle of device below:
Access electrode by detection human body, antistatic clothing accesses the resistance between electrode, and sends into bridge arm ratio
Relatively circuit, electric bridge comparison circuit compares the upper limit of this measured resistance and antistatic clothing on-line testing acceptability limit
The lower limit of (being called for short upper limit resistance value) and antistatic clothing on-line testing acceptability limit (is called for short lower limit resistance
Value) magnitude relationship.
Measurement result, through the logical judgment of controller (single-chip microcomputer), drives measurement result indicating circuit,
Carry out acousto-optic instruction, if output is in display screen or alarm lamp sends the light of different colours or has
Voice broadcast or warning are blown a whistle and are mutually combined etc..
Tester also has correspondence with foreign country and control circuit simultaneously, by telecommunication circuit, measurement result is transmitted out
To computer or other equipment, conveniently record and manage or form more complicated system.Control interface
The occasion of application, for be controlled external equipment according to measurement result, can be according to measurement result such as
No qualified, the switch etc. of access control.
Below in conjunction with the accompanying drawings 2,3, illustrate electric bridge comparison circuit and work process thereof.
Wherein Rx represents that human body accesses electrode, antistatic clothing accesses the resistance between electrode, i.e. measured resistance.
R1, R2, R3 are fixed resistance, wherein R1, and the voltage of R2 dividing potential drop output is upper limit fiducial value.R1、
R2, R3 and Rx constitute an electric bridge of upper limit comparison circuit.
After the voltage exported after R1, R2 dividing potential drop and the dividing potential drop of Rx and R3, the voltage of output is concurrently accessed ratio
Relatively device, the output of comparator enters level conversion and logic judging circuit after low pass filter filters.
In like manner, R4, R5, R6 are fixed resistance, wherein R4, and the voltage of R5 dividing potential drop output is lower limit ratio
Relatively being worth, R4, R5, R6 and Rx constitute an electric bridge of lower limit comparison circuit.Export after R4, R5 dividing potential drop
Voltage and Rx and R6 dividing potential drop after output voltage be concurrently accessed comparator, the output warp of comparator
Level conversion and logic judging circuit is entered after crossing low pass filter filtering.
Measured resistance Rx meets more than qualified lower limit the most simultaneously and is just judged to conjunction less than the qualified upper limit
Lattice.All do not include acceptability limit less than qualified lower limit or more than the measured resistance of qualified higher limit and referred to
Illustrate.
Because the qualified upper limit resistance value of antistatic clothing on-line testing is bigger, generally in 10E10 magnitude,
Can introduce interference, therefore the comparator output terminal in electric bridge rear class accesses one-stage low-pass filter, low pass filtered
The output result of ripple device just reflects the magnitude relationship of RX and the qualified upper limit resistance value of setting.By level
Conversion and logical judgment can show whether measured resistance falls into acceptability limit.
The above is only the preferred embodiment of the present invention, it is noted that general for the art
For logical technical staff, under the premise without departing from the principles of the invention, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection scope of the present invention.Although additionally, this specification making
With some specific terms, but these terms are only used to conveniently illustrate, do not constitute the present invention
Any restriction.
