Abstract
The invention discloses a universal electric furnace with warning and fingerprint recognition functions. The universal electric furnace comprises a universal electric furnace body, a knob switch, a fingerprint recognizer, a limiting mechanism, a temperature sensor and a buzzer. The liming mechanism comprises an electromagnet, a reset spring and a locking pin. The fingerprint recognizer is mounted on the outer wall of the universal electric furnace body. After recognizing fingerprint information of a user, the fingerprint recognizer transmits an instruction for switching on a circuit to a control unit; the control unit switches on the electromagnet and the circuit in the universal electric furnace body, the electromagnet starts to be powered on, magnetic force of the electromagnet attracts the locking pin back into a mounting hole, and meanwhile the locking pin gradually compresses the reset spring; when the locking pin completely enters a pin hole of a pin base, the knob switch loses limitation of the locking pin, the user can rotate the knob switch and operate the universal electric furnace, and therefore informationized operation management of the universal electric furnace is achieved. In addition, if the temperature in the universal electric furnace exceeds a set value, a buzzer will send out a warning signal.

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 with warning and fingerprint identification function, by the unlatching of the functional realiey switch of fingerprint recognition, the information system management to furnace operation can be realized.
There is a universal electric furnace for warning and fingerprint identification function, comprise universal electric furnace, rotary switch, Fingerprint Identification Unit, position-limit mechanism, temperature sensor and buzzer;
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 finger print information of user, and control unit controls the break-make of electromagnet and universal electric furnace internal circuit;
Described temperature sensor is arranged on universal electric furnace inside, and temperature sensor Real-time Feedback universal electric furnace internal temperature values, if universal electric furnace internal temperature exceedes setting value, buzzer sends alarm signal.
Operation principle: finger was placed on Fingerprint Identification Unit by user before use universal electric furnace, after Fingerprint Identification Unit identifies the finger print 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 fingerprint recognition, 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 fingerprint recognition, open protective cover, stopped the violation operation of layman to instrument.
(2) universal electric furnace of the present invention is with warning function, and when universal electric furnace internal temperature exceedes setting value, buzzer sends alarm signal, can reduce the generation of security incident.
(3) construction of switch with fingerprint recognition of the present invention is simple, is easy to realize, extends to Internet of Things field, realize the information system management to conventional instrument.
