A self-opening universal electric furnace switch with counting and face recognition functions

Abstract

The invention discloses an automatic-opening universal electric furnace switch with a counting and face recognition function. The automatic-opening universal electric furnace switch comprises a protective cover, a knob switch, a face recognizer, a control unit, a pin seat, an electromagnet, a locking pin, a return spring, a torsion spring, a pin shaft and a counter; one end of the protective cover is movably connected with a universal electric furnace shell through a rotating shaft, the rotating shaft is sleeved with the torsion spring, the bottom of a pin hole in the other end of the protective cover is sequentially provided with the electromagnet, the return spring and the locking pin, and the electromagnet is connected with a circuit inside the universal electric furnace through the control unit; after the identity information of a user is recognized by the face recognizer, command information is transmitted to the control unit, the limitation of the locking pin to the protective cover is lost, the protective cover is automatically bounded off and opened under the effect of the torsion spring, when the knob switch is rotated by the user, a counting switch on the counter is triggered by a pin shaft, and the operating information and operating time at the moment are recorded by the counting switch and displayed by virtue of a display screen, so that the informatization operation management for the universal electric furnace can be realized.

Description

technical field [0001] The invention relates to a switch for a universal electric furnace, in particular to a self-opening universal electric furnace switch with counting and face recognition functions, which belongs to the technical field of mechanical structures. Background technique [0002] At present, large-scale construction quality inspection companies need to use various types of test instruments to sample, analyze and inspect buildings when conducting inspection tests, such as using a universal electric furnace to heat and sample samples for analysis. [0003] The operator needs to fill in the operation record after each test operation, which includes the opening time of the instrument and the number of times of use. Due to the level and sense of responsibility of the operator, there are often cases of forgetting or omissions, which makes the test There are hidden dangers in data and equipment management, which is not conducive to the realization of scientific test ...
