05. Application Cases
01. Background and Demand:
The seat belt is often referred to as the "life belt," ser ving as the most fundamental and critical occupant protection device during car accidents.Statistics show that wearing a seat belt can reduce the mortality rate by 57% in frontal collisions, 44% in side impacts, and 80% in rollover accidents. Many countries have made it mandator y for drivers and passengers to wear seat belts, imposing fines for non-compliance. The purpose of the seat belt detection system is to utilize IoT technology for effective seat belt management, reminding passengers to wear seat belts and reducing secondar y injuries caused by accidents.
02. System Topology Introduction:
1. Seat cushion sensor and seat belt socket The seat cushion sensor detects whether someone is sitting in the seat, the seat belt socket detects whether the passenger's seat belt is fastened, and the detection result is output to the detection terminal.
2. Terminal detection The detection terminal packages the detection results of the seat cushion sensor and seat belt socket, and sends them to the safety reminder host through wireless signals at regular inter vals. One detection terminal can detect the status information of one or two seats.
3. Seat belt host The seat belt host receives signals from the detection terminal, displays the results on the screen, and outputs audio signals to drive the car speaker through the car amplifier, reminding passengers who have not fastened their seat belts to do so. The data is uploaded to the backend system through the 4G network .
4. Backend system and mini program Administrators can remotely view the seat and seat belt fastening status of vehicles in the backend system, per form location queries, and remotely manage device
03. Equipment Introduction:The seat belt host is installed at the front of the car and is responsible for receiving signals from the detection terminal, displaying the results on the screen, and outputting audio signals to drive the car speaker through the car amplifier, reminding passengers who have not fastened their seat belts to do so. The data is uploaded to the backend system through the 4G network.
04. S o f t w a r e S y s t e m F u n c t i o n Introduction: The system administrator logs in by entering an account and password to remind the system to view data. People without permission cannot view the data, which better ensures information confidentiality
