Smart building fire protection system based on Huawei LiteOS

File description:
Smoke.zip is the complete project code. (VScode is version 1.52.1, using IoT link plug-in, Bear Pie development board)
oc_smoke_template.c is the core code. (Contains the core tasks of the project, including data collection and display tasks. Data upload tasks, command issuance tasks, alarm tasks. And complete design logic)
Intelligent-Building-Fire-Protection-System.pdf is the project document.
Other documents are related hardware reference materials.
The design of each layer of the three-layer architecture of the Internet of Things is as follows:
Perception layer: mainly uses smoke sensors and flame sensors to sense the environment for data collection, and display it on the LCD display. STM32L431 controls the actuator (relay), communication module (NB-IoT module BC35-G, GSM module SIM800C), and alarm terminal (voice module JQ8900, LED) to perform corresponding functions.
Network layer: Mainly responsible for uploading smoke value and alarm status value data (BC35-G) and making calls (SIM800C).
Application layer: Huawei Cloud is responsible for analyzing platform data packets, displaying data in real time and pushing alarm information (SMS alarms and Huawei Cloud platform alarms).
