Умные Часы LoRa

flux

Понял: вы хотите сделать умные часы для безопасности работников железнодорожного пути с LoRa-связью.
Рекомендуемая архитектура:
  • MCU + LoRa: ESP32-S3 или nRF52 + SX1262/SX1276 LoRa-модуль
  • Датчики безопасности: акселерометр/гироскоп для падения, кнопка SOS, вибромотор, зуммер
  • Навигация: GNSS/GPS-модуль для координат работника
  • Питание: LiPo 3.7 В, зарядка через USB-C, защита батареи, DC/DC или LDO
  • Индикация: небольшой OLED/LCD или светодиоды
  • Связь: LoRa до базовой станции вдоль пути; опционально BLE для настройки через телефон
  • Корпус: влагозащита, ударостойкость, удобная кнопка SOS в перчатках
Для железной дороги я бы заложил функции:
  1. SOS-сигнал с координатами.
  2. Обнаружение падения/неподвижности.
  3. Вибро/звуковое предупреждение при опасности.
  4. Периодическая отправка местоположения.
  5. Контроль заряда батареи.
  6. LoRa-сеть “часы → базовая станция → диспетчер”.
Важно: текущий проект открыт как компонент вибромотора LCM0827A3038F, и у вас уровень доступа comment, поэтому я не могу прямо изменить схему этого проекта. Лучше создать отдельный проект часов или форкнуть/создать новый дизайн, где этот вибромотор будет одним из компонентов.
Если хотите, я могу следующим сообщением подготовить полную структуру схемы для LoRa safety smartwatch: список компонентов, блок-схему питания, соединения MCU/LoRa/GPS/датчиков и рекомендации по батарее.
