Abstract

The invention discloses a low-cost file security cabinet, which comprises a cabinet body and a cabinet door on the cabinet body. The cabinet door is provided with an electronic lock, a keypad and a handle, the electronic lock is connected with a control circuit which is arranged on the inner side of the cabinet door, the control circuit comprises a single-chip microcomputer, a keypad circuit, a sensor circuit, an alarm circuit and a data memory, and the inner side of the cabinet door is provided with a door magnetic sensor which is connected to the single-chip microcomputer through the sensorcircuit. On-off control of the security cabinet is realized through a combination lock, and the door magnetic sensor and the alarm circuit form an alarming system. Code storage is completed by an EEPROM chip, convenience in code storage and setup is achieved, and codes can be changed as needed periodically.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to a low-cost file safe. Background technique [0002] In the process of enterprise management, a series of security and anti-theft issues such as the preservation of internal documents and confidential files of the enterprise are not optimistic. Due to its simple structure and principle, traditional mechanical locks are frequently picked up, and people often need to carry multiple keys, which is extremely inconvenient to use. In order to meet people's requirements for anti-theft and increase the security of locks, electronic combination locks with anti-theft functions have emerged as the times require, such as keyboard-type electronic combination locks that are widely used in safes, safes and vaults. Compared with traditional mechanical locks and expensive Fingerprint locks, image recognition locks, etc. Electronic combination locks are more and more widely used due to th...

Due to the simple structure and principle of traditional mechanical locks, it is not uncommon to be picked, and people often need to carry multiple keys, which is extremely inconvenient to use

In order to meet people's requirements for anti-theft and increase the security of locks, electronic combination locks with anti-theft functions have emerged as the times require, such as keyboard-type electronic combination locks that are widely used in safes, safes and vaults. Compared with traditional mechanical locks and expensive Fingerprint locks, image recognition locks, etc. Electronic combination locks are more and more widely used due to their advantages of high security, low cost, and low power consumption. However, the current electronic combination locks still have poor stability, complicated operation, and poor function more simple question
