Embodiment 1
[0041] This embodiment provides a system for reminding that a seat belt is not fastened, which includes: a first detection module, a second detection module, a control center module, and a reminder module. The first detection module is used when a passenger passes by a vehicle. Detecting and acquiring passenger information when the vehicle door; the second detection module is used to detect and acquire the seat belt locked state at the seat in the vehicle when the vehicle is ignited and the vehicle speed is within the preset starting speed range and acquire the serial The current current value of the series circuit connecting all seats, and when the seat belt lock at the seated seat is in the locked state, detect and obtain the seat belt voltage drop value and obtain the pre-seat belt voltage drop value according to the passenger information, Send the seat belt locked state, seat belt voltage drop value, and pre-seat belt voltage drop value to the control center module; the cont...
Embodiment 2
[0062] This embodiment provides a system for reminding that a seat belt is not fastened, which includes: a first detection module, a second detection module, a control center module, and a reminder module. The first detection module is used when a passenger passes by a vehicle. Detect and acquire passenger information when the vehicle door is closed and after the vehicle door is closed; the second detection module is used to detect and acquire the seat belt at the seated seat in the vehicle when the vehicle is ignited and the vehicle speed is within the preset speed range The locked state and the current current value of the series circuit connecting all the seats in series are obtained, and when the seat belt lock at the seated seat is in the locked state, the seat belt voltage drop value is detected and obtained and the forecast is obtained according to the passenger information The seat belt voltage drop value, including the seat belt locked state, the seat belt voltage drop ...
Embodiment 3
[0079] Based on the fact that this embodiment is basically the same as the second embodiment, the difference is that: in practical applications, the parallel resistors corresponding to the seat belts of each seat are set in series in the same circuit, but the resistors will fail during use. As a result, the resistance point is directly connected, so that the seat information feedback unit is short-circuited before the person is seated. When the person is not seated, the seat information is accurately fed back. Therefore, the seat information feedback unit is also used for detecting The seat belt of each seat corresponds to the short circuit or open circuit of the parallel resistors, that is, the micro processing unit of the seat information feedback unit has an input terminal and an output terminal for resistance detection, which are respectively connected to the two ends of the resistor , And when the resistance fails and the resistance point is directly turned on, the micro pr...
