基于超声波传感器及蓝牙技术的来车提示装置电路设计

Circuit Design of Vehicle Arrival Prompt Device Based on Ultrasonic Sensor and Bluetooth Technology

小区出入口保安亭的安保人员没能及时发现来车的时候,车主经常以鸣车的方式来提醒安保人员开门。鸣车噪音给小区居民带来很大的烦恼,尤其在安静的晚上,噪音大大地降低了小区居民的生活质量。为了减少小区出入口鸣车的情况,应用超声波传感器及蓝牙技术设计来车提示装置的电路。应用超声波传感器自动感应来车,使用蓝牙技术将来车提示信号传达到保安亭内,触发声光提示电路。

When the security personnel in the security booth at the entrance and exit of the community fail to find the coming vehicle in time,the vehicle-owner often reminds the security personnel to open the door by Honking.The noise of vehicle whistling brings a lot of trouble to the residents,especially in the quiet night,the noise greatly reduces the quality of life of residents in the community.In order to reduce the vehicle whistling at the entrance and exit of the residential area,the ultrasonic sensor and Bluetooth technology are used to design the circuit of the vehicle reminder device.The ultrasonic sensor is used to automatically sense the incoming vehicle,and Bluetooth technology is used to transmit the vehicle prompt signal to the security booth,and trigger the sound-light prompt circuit.
