Используя электромагнитные замки, RFID-считыватели, микроконтроллеры ESP32 и сенсорные экраны, мы разработали систему контроля доступа, которую можно разблокировать, проведя по карте и введя пароль.

Тогда мне нужно многое узнать о радиочастотах.

Если все пойдет хорошо, возможно, он сможет добиться большего.

Я уже закончил его. Я обновлю его.

Краткое введение

Умный дом становится все более распространенным с развитием технологий, эта статья будет посвящена аспектам безопасности проекта интеллектуального контроля доступа.
В этой статье используется сенсорный экран STONE для отправки команд на MCU для управления реле и модулем MFRC522.
Принцип считывания карт: путем управления RFID-RC522 модуль, определить ID карты ID близко к ID карты, а затем определить, существует ли ID в базе данных слово типичный, ID является типичным значением слова, если существование проверки через, а затем распечатать соответствующее имя, а затем привести в действие электромагнитный замок таким же образом.

Необходимые материалы

ESP32
Электронный замок KOB
Реле
Сенсорный дисплей STONE STWI070WT-01
Модуль MFRC522

Реализованная функция

1. регистрация карты.
2. регистрация имени пользователя и пароля.
3. проведение картой для разблокировки электронного замка.
4. Имя пользователя и пароль для разблокировки электронного замка.

Схема подключения

Разработка графического интерфейса пользователя

То, что я увидел нифига не удобно, больше похоже на демку от СТМ или подобное, но только не для устройств в продажу.

ЗЫ. Замков с RFID картами более, чем дофига и они гораздо проще в работе, ИМХО...

Это китайцы рекламируют свой дисплей - уже предельно очевидно.

Жуть какая! Ну и "протокол"...
