Because in my community, I always see a lot of stray cats, regardless of age and species. When I meet them, they are not necessarily alive. The cold and food shortage will threaten their lives. And every time I want to help them, I can't just happen to be able to provide them with food. Even if I can give them food, the stray cat population and its offspring will continue to wander. So my idea is how to help them live better. I plan to build a portable stray cat rescue station that can be placed in areas where stray cats are present to provide them with warmth and food. # Solution: My solution is to design a wireless constant temperature device that can detect the temperature in the cat's nest at all times to determine whether the heating device is turned on and off. Then equip it with feeding equipment, and detect whether there is enough food in the cat's food bin. Through wireless data transmission, maintenance personnel can decide whether to add food to the equipment according to the data. This device includes the following modules: Power supply module: as the power source of the entire device and other subsystems Heating module: to control the device temperature Main control module: transmit real-time data of the device Casing and heating layer: enhance the warmth of the device at the physical level #Solution components: ## Subsystem 1: Power supply module Overview: This subsystem uses solar panels and lithium batteries to realize the device power supply system. While avoiding the trouble of replacing batteries, it can also realize the convenience of this device and can be installed outdoors. It is also conducive to the operation of subsystem 2 (heating module) at night. Design: Power generation method: solar panels can generate solar energy outdoors Power storage method: use lithium batteries of suitable capacity to store electricity ## Subsystem 2: Heating module Overview: This subsystem automatically controls the temperature in the device through heating equipment and temperature and humidity sensors Design: Heating method: heating by laying heating wires in the device Temperature control method: use temperature and humidity sensors to detect whether the temperature in the device is lower than the set value and turn on the heating device, and the temperature can be monitored in real time through subsystem 3 (main control module) ## Subsystem 3: Main control module Overview: Detect data in the device and transmit data wirelessly to the receiving station Design: Transmission method: Use LoRa devices for transmission to ensure that data is obtained when there is no network in the wild. Reserve detection: Use pressure or infrared sensors to detect food residue Power monitoring: Real-time recording of battery remaining power Activity detection (optional): Infrared sensor detects cat entry and exit (optional: camera monitoring, but it is not suitable for no network and the price is higher.) ## Subsystem 4: Shell and heating layer Overview: Use physical methods to assist and strengthen the role of subsystem 2 (temperature control module), and reduce power consumption. Design: Shell: Waterproof plastic board, aluminum plate or 3D printing material, and a metal frame about 10 cm above the ground to prevent rainy weather Inner layer: Warm and fireproof foam board or other insulation material # Criterion For Success: This design would be considered successful if The heater will automatically turn on and off when the temperature is within the set value range When there is not enough food in the feeding bowl, it will automatically dispense food Ability to obtain various real-time data on the LoRa master station |
