# Problem
Today, both the primary and secondary industries need to carry out technology-led industrial upgrading, in such a process, how to efficiently detect the work flow is a major problem. For example, in the fields of agricultural inspection, power line and infrastructure inspection, environmental protection and wildlife monitoring, an effective, high-speed and wide-ranging inspection method will increase the productivity and accuracy of related industries.

# Solution Overview
The solution we give is to develop an eVTOL drone that can meet a certain load bearing, set up corresponding communication modules and cameras for it, and transmit real-time data back to the data cloud we build on the server, so as to achieve a large range and long distance accurate detection.

# Solution Components
## Foam Board Body
The foam plate body provides lower weight, thus reducing energy consumption and ensuring adequate performance in terms of movement and acceleration, while it has good insulation, which can effectively reduce heat transfer and noise diffusion. During the engineering phase, its characteristics made the air frame easy to process and had good impact protection characteristics. At the same time, foam board is also a more economical and environmentally friendly approach.

## Power System
Internal micro controller for A/D conversion and initial signal processing ( Atmel atmega328
SIM Card Service )
Use SIM cards to provide identity authentication and data transmission in drone and cloud communications. SIM card technology allows drones to connect to a specific cellular network operator and use its network infrastructure to communicate remotely. In this way, the drone is not limited by distance, is able to perform long-distance missions, and can upload data to the cloud in real time. At the same time, it also ensures continuous connectivity between the drone and the cloud, and the drone can maintain a continuous network connection in the covered area. This allows for prolonged monitoring or data acquisition activities while enabling near real-time data analysis and decision support.

## Camera
Cameras rely on built-in image sensors, such as CMOS or CCD, to convert light into electronic signals. These sensors divide the screen into pixel points, each point can record color and brightness information, analog cameras will capture the image into analog signal output; The digital camera further converts the analog signal to A digital signal through an A/D (analog-to-digital) converter. By reducing its size through encoding and compression algorithms (such as H.264, H.265) to reduce the bandwidth requirements during transmission, the compressed video data can be transmitted through the SIM's cellular network and stored in the cloud.

# Criterion for Success
Our aircraft must be able to lift more than 2kg and maintain smooth horizontal and vertical flight, while our cloud needs to be stable and receive video information from drones flying on the road

Problem:

The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
