A kind of universal electric furnace switch with face identification functions
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 face identification functions, 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 face identification functions, comprise rotary switch, recognition of face device 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 recognition of face device is fixedly mounted on the outer wall of universal electric furnace, and recognition of face device 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: user use universal electric furnace before by the camera of face orientation face recognizer, identify after the facial information of the lower user of camera shooting, after recognition of face device 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 recognition of face device 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, the personnel that gathered facial information just open protective cover by recognition of face, have 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.

Fig. 2 is the structural representation of position-limit mechanism of the present invention.
Wherein, 1-universal electric furnace, 2-rotary switch, 3-recognition of face device, 4-electromagnet, 5-back-moving spring, 6-locking pin.
Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
The invention provides a kind of universal electric furnace switch with face identification functions, as shown in Figure 1, described switch comprises rotary switch 2 to its structural representation, recognition of face device 3 and position-limit mechanism;
The rotating shaft of described rotary switch 2 is processed with radial spacing hole;
The structural representation of described position-limit mechanism as shown in Figure 2, it is arranged in the installing hole of universal electric furnace 1 housing, installing hole is corresponding with the position in rotary switch 2 upper limit hole, position-limit mechanism comprises electromagnet 4, back-moving spring 5 and locking pin 6, the bottom of installing hole is provided with electromagnet 4, back-moving spring 5 and locking pin 6 successively, electromagnet 4 is under non-"on" position, the head of locking pin 6 to be arranged in outside installing hole and to insert the spacing hole of rotary switch 2, and electromagnet 4 is connected by the circuit of control unit with universal electric furnace 1 inside;
Described recognition of face device 3 is fixedly mounted on the outer wall of universal electric furnace 1, and recognition of face device 3 sends command information to control unit after identifying the identity information of user, and control unit controls the break-make of electromagnet 4 and universal electric furnace 1 internal circuit.
Operation principle: user use universal electric furnace 1 before by the camera of face orientation face recognizer 3, identify after the facial information of the lower user of camera shooting, after recognition of face device 3 identifies the identity information of user, the instruction of connecting circuit is sent to control unit, control unit connects the circuit of electromagnet 4 and universal electric furnace 1 inside, electromagnet 4 starts to power on, locking pin 6 sucks back in installing hole by the magnetic force of electromagnet 4, locking pin 6 progressively compression reseting spring 5 simultaneously, after in the pin-and-hole that locking pin 6 enters key seat completely, rotary switch 2 loses the restriction of locking pin 6, user just can rotate rotary switch 2, universal electric furnace is operated, this time use information is undertaken recording by recognition of face device 3 and is uploaded to outside host computer, realize the information-based operational administrative to universal electric furnace 1 thus.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
