Network dual-chip fingerprint access control and timing monitoring system and implementation method thereof

Abstract

The invention discloses a network dual-chip fingerprint access control and timing monitoring system and an implementation method thereof. The system comprises an access control unit and a server which are constructed through a wired or wireless network. The system is characterized in that the access control unit comprises a first fingerprint identification chip, a second fingerprint identification chip, a controller unit and a priority trigger circuit unit, wherein, the first fingerprint identification chip and the second fingerprint identification chip are arranged inside and outside a door body and are mutually independent; the controller unit is integrated with a clock circuit, a network interface and a single-chip CPU (central processing unit); the priority trigger circuit unit is bridged between the two fingerprint identification chips and the controller unit; and the server is connected with an independent fingerprint acquisition instrument through a USB (universal serial bus) interface. In the invention, the dual-chip fingerprint access control and timing monitoring system is composed of the access control unit and the server based on the network; by adopting the two fingerprint identification chips which are respectively arranged inside and outside the door body, a user can more conveniently get in and out of the access control system in two ways, and the fingerprint identification chips at the two sides record the access control opening time when the user gets in and out of the system; and a new idea that the access control system is linked with enterprise resource planning (ERP) and office management is provided.

Description

technical field [0001] The invention relates to the application of a fingerprint identification system, in particular to an access control monitoring system based on fingerprint identification, which has the functions of recording the time of access control opening and closing and assisting database management. Background technique [0002] Access control, that is, access management control system. It is a digital management system that manages the entry and exit of personnel. The current types of access control systems mainly include password identification access control systems, card identification access control systems and portrait recognition access control systems. Among them, the password identification access control system has the disadvantage of poor security because the password is easy to leak or be cracked; and the card identification access control system is also difficult to achieve two-way control because the card is easy to be borrowed, copied, or damaged ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing access control monitoring systems based on fingerprint identification are often set up on the side of the door body, and there are great security risks in use.

For example, if the fingerprint identification chip is installed on the outside of the door, after the user enters another space through fingerprint identification, if the inner access control switch fails, the user is very likely to be locked in another space, and Rescuers will also be at a loss because the fingerprints cannot be matched.

In addition, most of these fingerprint access control monitoring systems do not have the time recording function, and there is a blank in the historical control technology of access control opening and closing. It can be used as a separate attendance machine without the access control function, or it can only be used as a single-side access control, with only one side of the access control opening and closing recording function, and cannot be used as a reference for attendance
