I. Introduction

Overview

Design problem for an application of 32-bit MCUs ( STM32F411). You can freely choose the design problem related to smart factory, smart home system or any other related to our mechanical and control engineering.

You need explain the overview of the design problem with a diagram and brief abstract

Please refer to past design problem

II. Problem

Problem Description

Detail description of the problem goes here.

Your problem must have at least 3 modes(states). Explain necessary states(modes) and description

Example diagram:

Description of system modes, how your MCU should function and more

For example:

1. System Mode:

MODE

Description

Normal Mode (NORM_MODE)

Pressing MODE_button (B1 of MCU_1) toggles from NORM_mode 🡨🡪SECUR _mode

Security Mode (SECUR_MODE):

Pressing STOP_button (B1 of MCU_2) resets from SIREN_mode to SECUR_mode.

2. Front Door:

MODE

Description

Normal Mode (NORM_MODE)

When a person is detected within the given distance from the door(outside): Keep turning on the door light as long as the person is present. When a person is detected inside the house nearby the door: Turn on the door light for given period of time and does not generates the SIREN _TRG trigger.

Security Mode (SECUR_MODE):

When a person is detected within the given distance from the door(outside): Keep turning on the door light as long as the person is present and sends the VISITOR_LOG message to the server. When a person is detected inside the house nearby the door: Keep turning on the door light and generates the SIREN _TRG trigger.

Comments

Door Person detect (front)

Ultrasonic distance sensor

Sampling 0.1 sec Check object presence within 30cm Generates PERSON_OUTSIDE flag

Need to check for outlier measurements (at least 7/10 Postive) VISITOR_LOG under SECUR_MODE

Door Person detect (inside)

PIR motion sensor

Edge trigger Generates PERSON_INSIDE flag
