Internet-of-Things alarm device for monitoring door opening sounds of automobile

Abstract

The invention discloses an Internet-of-Things alarm device for monitoring door opening sounds of an automobile. The Internet-of-Things alarm device for monitoring the door opening sounds of the automobile comprises a CPU monitoring chip, a GPS communication positioning module and a sound monitoring circuit. A sound sensor is connected to the signal acquisition end of the sound monitoring circuit. The signal output end of the sound monitoring circuit is connected with the CPU monitoring chip. The signal output end of the CPU monitoring chip is connected with the GPS communication positioning module. A sound learning key is connected to the CPU monitoring chip. The sound monitoring circuit processes a sound signal acquired by the sound sensor and then transmits the processed sound signal to the CPU monitoring chip. The CPU monitoring chip outputs an alarm signal to the GPS communication positioning module. The Internet-of-Things alarm device for monitoring the door opening sounds of the automobile is simple in structure, small in size, convenient to use and good in anti-theft effect. Sounds which are given out when an automotive door is opened illegally in a fortified state can be monitored in real time, the door opening sounds of the automobile can be accurately compared, a warming message can be remotely sent to the networked owner of the automobile, the performance of original automobile circuits is guaranteed, the stealthiness is good, and the automotive door opening sounds of various types of automobiles can be stored.
