# PROBLEM

Traditional fire protection systems often rely on outdated equipment and simplistic detection methods, leading to inefficiencies and potential safety hazards. Current smoke sensors, sound alarms, and manual alarm buttons lack the sophistication needed to accurately detect and respond to fire incidents promptly. Additionally, conventional systems may suffer from high rates of false alarms, causing unnecessary disruptions and desensitizing occupants to genuine threats.

Moreover, the limited capabilities of traditional systems hinder their ability to adapt to evolving fire risks and environments. With the increasing complexity of modern buildings and the prevalence of diverse fire hazards, there is a growing need for intelligent fire protection solutions that can analyze fire information comprehensively, distinguish genuine threats from false alarms, and transmit critical fire signals remotely to safeguard lives and property effectively.

# SOLUTION OVERVIEW

Enhance the efficiency of conventional fire alarm apparatus while modernizing standard smoke sensors, auditory and visual alert systems, and manual alarm activation mechanisms. This advanced system is equipped with the capability to meticulously analyze data derived from fire sensors, enabling precise determination of fire occurrences. Additionally, it facilitates remote transmission of fire alerts, thereby ensuring swift responses to potential hazards, ultimately safeguarding both lives and property.

# SOLUTION COMPONENTS

## BLUETOOTH CONTROL SYSTEM:

- Apply a user-friendly mobile application interface for remote control and monitoring of the fire protection system via Bluetooth connectivity.

- Implement secure Bluetooth communication protocols to ensure data integrity

## CIRCUIT SYSTEM:

- Design and prototype circuit boards to integrate various sensors, alarms, and communication modules into a cohesive system.

- Conduct rigorous testing and optimization of circuit designs to ensure reliability and efficiency in operation under different environmental conditions.

## SENSOR SYSTEM:

- Research and select advanced smoke sensors with improved detection capabilities.

- Integrate additional sensors for detecting environmental factors like temperature, humidity, and gas levels to enhance fire detection accuracy.

## PHYSICAL APPEARANCE SYSTEM:

- Design aesthetically pleasing enclosures and housings for the fire protection system components, considering factors such as durability, ease of installation, and maintenance.

- Incorporate visual indicators and status lights into the design to provide intuitive feedback to users about the system's operational status.

## DATA ANALYSIS SYSTEM:

- Develop algorithms for real-time analysis of sensor data to accurately detect and classify fire incidents while minimizing false alarms.

- Implement data logging and storage mechanisms to maintain a record of fire events and system performance for later analysis and optimization.

## USER INTERFACE SYSTEM:

- Design intuitive interfaces for both physical control panels and mobile applications to facilitate user interaction with the fire protection system.

- Conduct usability testing and gather feedback to refine the user interface design for enhanced user experience and accessibility.

# CRITERION FOR SUCCESS

## RELIABILITY AND ACCURACY:
The system should demonstrate consistent and accurate fire detection capabilities, minimizing false alarms while promptly identifying genuine fire incidents.

## REMOTE ACCESSIBILITY
Users should be able to access and control the fire protection system remotely via Bluetooth connectivity or mobile application, ensuring timely response and management of fire-related emergencies.

## ENERGY EFFICIENCY
Energy consumption should be optimized to maximize battery life and minimize environmental impact, ensuring continuous operation even during power outages.

## COMPLIANCE AND SAFETY
The system should meet or exceed industry standards and regulatory requirements for fire protection, ensuring the safety of occupants and compliance with legal obligations.

## RELIABLE COMMUNICATION
The communication system should demonstrate high reliability and resilience, ensuring seamless transmission of fire alerts and system status updates to designated recipients in real-time.

A crowd-sourcing urban air quality monitoring system with bikes

Featured Project

**Problem**

For public bike users, someone may concern about the air quality in which they are currently riding, as well as the places they are going to. However, currently there is no such an air quality monitoring system which provides air quality information in specific areas inside a city such as Haining.

**Solution Overview**

The idea is to apply air quality monitoring devices on the public bike system. The public bike system in Haining is a perfect carrier for IoT (Internet of Things) devices and urban sensing since it has a large and stable user group and all bikes are managed by official organization which means unified modification on all bikes can be done. A monitoring device integrated on the bike can provide the real-time information that users want to know and share data with other users through a cloud server. A real-time air quality map can be created for users with the contribution from all running bikes.

**Solution Components**

Subsystem 1 – on-bike air quality monitoring device. The subsystem is a stm32 microcontroller based design, integrated with air contaminant sensor, speed meter and data transmission modules. Once connected to a smartphone, the subsystem will keep transmitting real-time data to the smartphone.

Subsystem 2 – Software include a user interface and a server. The user interface can be either an app or a website on smartphone. The user interface receives sensor data from the hardware subsystem, displays the real-time statistics, uploads sensor data to server and receives the air quality map from server. The server processes data from all running bikes, creates a real-time air quality map and returns it back to users.

**Criterion for Success**

1. Success of data collection: stable real-time statistic display on user interface, stable data collection on server.

2. Air quality visualization: The air quality map correctly reflects the air quality in Haining city. For example, the concentration of air contamination should be higher in heavy traffic than in intl campus.

3. Speed control: The on-bike device or smartphone should give an alert when the monitored speed exceeds the upper limit or the user set range. This is not the core function of our design, but we add it as we think the function makes sense for safety purpose.
