A pressure-sensitive electronic protection device

Abstract

The invention provides pressure sensing type electronic protecting equipment which comprises a box door, a control panel, a box body and a printed circuit board. The control panel is arranged on the surface of the box door. The control panel is composed of an electronic box lock, a lock hole, a display screen, digital keys, a loudspeaker and an alarm. A key information transfer unit, a pressure sensor, an analog-to-digital converter, an inlaid type central processing unit, a storer, a switch control unit, a bell control unit and an alarm control unit are welded to the printed circuit board. Compared with the prior art, the pressure sensing type electronic protecting equipment has the following beneficial effects that if a user hopes to unlock the electronic box lock, a specific code needs to be input; the code is input effectively only when the pressure applied to the digital keys is larger than a critical value in the inputting process; the safety is improved, the design is ingenious, the market competitiveness is improved, and the purposes of being simple in structure, reasonable in design and attractive in appearance are achieved.

Description

technical field [0001] The invention is a pressure-sensing electronic protection device, which belongs to the field of office safes with multiple verification methods. Background technique [0002] The safe is considered to have originated in Europe. At that time, the safe was just a solid thick wooden box hooped by an iron ring. In medieval European paintings, you can occasionally see a kind of wooden box with metal edging for holding gold and silver jewelry. Cabinet, this is the prototype of the safe. [0003] Until the beginning of the 19th century, about 200 years ago, with the growth of social wealth, there was a real market demand for safes, and European lock manufacturers began to turn to the safe industry. In 1818, the Chubb lock and safe manufacturing factory was established in London. . In 1825, the French FICHE-BAUCHE company was established, and these manufacturers then began to manufacture safes. In the late 18th century, Carron Co. in Scotland and Coalbrookd...
