Others 2020-04-06 10:59:09 views: null

1, design requirements and objectives

 

1. The basic functions of the system, requires the ability to fingerprint input, identify and remove, enable fingerprint recognition entry up to 1000, to achieve a successful fingerprint lock function. And a 4 * 4 keypad, to achieve password entry, modification and special features.
The functional requirements and cost, choice STC89C52 microcontroller.
3. A reasonable choice of components, to complete the function keypad module, a clock module, a fingerprint recognition module, a display circuit design LCD12864.
4. Design of a hardware circuit Fig. Building hardware, programming, system debugging.

2, design ideas and solutions

 

The design is a design fingerprint lock microcontroller based system 51, it can achieve a successful lock function fingerprint identification, the fingerprint identification is successful, the indicator lights, lock relay, can enter; fingerprint identification is unsuccessful, the indicator is off, the relay It does not act, people can not enter in administrator mode fingerprint input can also be achieved, to remove fingerprints, emergency unlock and password change function, which deletes the fingerprint can be achieved delete the specified number of fingerprint fingerprints, and liquid crystal display-related display LCD12864 Steps. When the input and fingerprint identification, the fingerprint will display the corresponding prompt information on the number and related LCD12864 liquid crystal display. Hardware:
