#The 5th Lichuang Electronic Design Competition#Indoor temperature control and gas security alarm system

Note: * is a required field.

[Please fill in during the registration stage↓]

* 1. Self/Team Introduction

* 2. Brief Introduction of the Project

**Share a complete solution for building an IoT system, helping us to be familiar with the knowledge and simple applications of each link in the system, such as device terminals, user terminals, GPRS communication, server environment usage, and server TCP transparent transmission program implementation. This project is based on the concept of "Smart Home" to design an implementation plan that integrates a temperature control system for a confined space and a gas safety detection feedback system, which can be applied to office and home indoor temperature adjustment control and gas safety detection alarm. **The functional modules implemented in the project are as follows:

Equipment Terminal 1 (**Load Control Board**) Implemented functions: relay control of electric doors, windows, ventilation ducts and other motors to open and close doors, windows, ventilation ducts and other facilities; input node to check the real-time status of doors, windows, ventilation ducts, etc.; support device address encoding; serial communication remote control and status feedback.

Equipment Terminal 2 (**Data Acquisition Control Board**) Implemented functions: confined space temperature and humidity monitoring; infrared air conditioning temperature adjustment control; environmental five gas index detection; support device address encoding; serial communication remote control and status data feedback.

Communication module (**WIFI communication module**) Function: Local routing network connects to the server to realize serial data communication of terminal equipment.

Communication module (**GPRS communication module**) Function: Directly connect to the server via GPRS to realize serial data communication of terminal equipment.

Server device and user end data forwarding program (**Server TCP forwarding program**) Function: The TCP port running on the server listens to the device and user end data,
forwards , and is used for data forwarding between the device and user end.

User end (TCP debugging assistant simulation): Any TCP debugging assistant or software can control the device and view parameters by connecting to the server user port through the TCP client,
thereby realizing the control of the temperature system and the safety monitoring of gas in confined spaces.
