Embodiment Construction
[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0016] Such as figure 1 and figure 2 Shown, a kind of car collision warning device that is positioned at car seat, comprises microprocessor, signal transmitter, memory, four pressure sensors that are installed in different positions on car seat 100, and pressure sensor communicates with microprocessor through analog-to-digital conversion circuit The input end of the processor is connected, and the output end of the microprocessor is respectively connected with the signal transmitter and the memory.
[0017] The four pressure sensors are respectively the first pressure sensor 1, the second pressure sensor 2, the third pressure sensor 3, and the fourth pressure sensor 4. The first pressure sensor 1 is installed on the middle position of the upper surface of the car seat 100 seat cushion frame , when a collision occurs, the position ...

The invention provides an automobile collision alarm device on an automobile seat. The automobile collision alarm device comprises a plurality of pressure sensors mounted at different positions of theautomobile seat, a microprocessor, a signal transmitter and a memory, wherein the pressure sensors are connected with the input end of the microprocessor through an analog-digital conversion circuit,the output end of the microprocessor is separately connected with the signal transmitter and the memory, the pressure sensors send signals IN to the microprocessor, the microprocessor calculates a fitted collision signal Ci according to the formula: Ci=alpha1xI1+alpha2xI2+-+alphaNxIN, and the microprocessor compares the fitted collision signal Ci with a preset collision signal threshold C0; whenCi is larger than C0, the microprocessor judges that collision occurs, and the microprocessor sends an alarm signal to the signal transmitter; and when Ci is smaller than or equal to C0, the microprocessor judges that collision does not occur, the fitted collision signal is stored and recorded in the memory, potential road danger can be directly and effectively discovered through the analysis andmonitoring of data, and real-time alarm is realized.
Description
technical field [0001] The invention relates to the field of car seat collision alarms, in particular to a car collision alarm device located in the car seat. Background technique [0002] Car seats are important components to ensure the safety of passengers. When a collision occurs, they directly protect the driver and passengers. The current trend of car networking is obvious, but most of the car collision and early warning / alarm devices are located in the peripheral part of the vehicle, and the technical research on seat early warning / alarm during collision is not active enough. Since the car seat is in direct contact with the body of the member, when a collision occurs, various information about the human body during the car collision can be collected through the sensors preset in different areas of the car seat. Based on the information collected above, the severity of the car collision can be analyzed. Through the analysis and monitoring of human body data, road dang...
