Abstract
The invention discloses a universal electric furnace switch with a fingerprint identification function. The universal electric furnace switch with the fingerprint identification function comprises a knob switch, a fingerprint identification device and a limiting mechanism, wherein a radial limiting hole is formed in a rotary shaft of the knob switch through machining; the limiting mechanism is arranged in a mounting hole of a universal electric furnace shell body, and the limiting mechanism comprises an electromagnet, a reset spring and a locking pin; the fingerprint identification device is arranged on the outer wall of a universal electric furnace. After the identity information of a user is identified by the fingerprint identification device, an instruction of closing a circuit is sent to a control unit, the electromagnet is connected with the circuit inside the universal electric furnace by the control unit, the electromagnet starts to be powered on, and the locking pin is attracted back into the mounting hole by magnetic force of the electromagnet; meanwhile, the reset spring is gradually compressed by the locking pin, and the knob switch is not limited by the locking pin when the locking pin completely enters a pin hole of a pin boss, so that the knob switch is rotated by the user, the universal electric furnace is operated, and the information operation management of the universal electric furnace is achieved.
Description
Technical field
Invention relates to a kind of switch of universal electric furnace, is specifically related to a kind of universal electric furnace switch with identity recognition function, belongs to frame for movement technical field.
Background technology
At present, large-scale construction quality detects company when carrying out detection experiment to building and analyzing, and needs to use various dissimilar test apparatus to carry out sample analysis and detection to building, such as uses universal electric furnace to carry out heating sampling analysis to tested sample.
Operating personnel need to fill in operation note after carrying out test operation each time; record comprises opening time and the access times information of instrument; due to level and the sense of responsibility reason of operating personnel; often there will be the situation forgotten or fail to record; therefore make test data and hidden danger is existed to the management of equipment, be unfavorable for realizing scientific testing equipment management.
Summary of the invention
In view of this, the invention provides a kind of universal electric furnace switch with fingerprint identification function, by the unlatching of the functional realiey switch of identification, the information system management to furnace operation can be realized.
There is a universal electric furnace switch for fingerprint identification function, comprise rotary switch, Fingerprint Identification Unit and position-limit mechanism;
The rotating shaft of described rotary switch is processed with radial spacing hole;
Described position-limit mechanism is arranged in the installing hole of universal electric furnace housing, installing hole is corresponding with the position in rotary switch upper limit hole, position-limit mechanism comprises electromagnet, back-moving spring and locking pin, the bottom of installing hole is provided with electromagnet, back-moving spring and locking pin successively, electromagnet is under non-"on" position, the head of locking pin to be arranged in outside installing hole and to insert the spacing hole of rotary switch, and electromagnet is connected by the circuit of control unit with universal electric furnace inside;
Described Fingerprint Identification Unit is fixedly mounted on the outer wall of universal electric furnace, and Fingerprint Identification Unit sends command information to control unit after identifying the identity information of user, and control unit controls the break-make of electromagnet and universal electric furnace internal circuit.
Operation principle: finger was placed on Fingerprint Identification Unit by user before use universal electric furnace, after Fingerprint Identification Unit identifies the identity information of user, the instruction of connecting circuit is sent to control unit, control unit connects the circuit of electromagnet and universal electric furnace inside, electromagnet starts to power on, locking pin sucks back in installing hole by the magnetic force of electromagnet, locking pin progressively compression reseting spring simultaneously, after in the pin-and-hole that locking pin enters key seat completely, rotary switch loses the restriction of locking pin, user just can rotate rotary switch, universal electric furnace is operated, this time use information is undertaken recording by Fingerprint Identification Unit and is uploaded to outside host computer, realize the information-based operational administrative to universal electric furnace thus.
Beneficial effect:
(1) switch of the present invention by the unlatching of the functional realiey protective cover of identification, can realize the information system management to furnace operation.On the one hand, operating personnel can be recorded to the service time of universal electric furnace and access times, facilitate checking of subsequent experimental data and searching of person liable; On the other hand, only have the talent of fingerprint in fingerprint base by identification, open protective cover, stopped the violation operation of layman to instrument.
(2) construction of switch with identification of the present invention is simple, is easy to realize, extends to Internet of Things field, realize the information system management to conventional instrument.
