Vehicle alarm device

Abstract

The invention discloses a vehicle alarm device, and belongs to the technical field of electronics. The vehicle alarm device comprises a box body, a pressure sensor, elastic pieces and connection devices, wherein two ends of the elastic pieces and two ends of the connection devices are respectively fixed on the bottom surface and an upper cover of the box body; one end of the pressure sensor is fixed on the bottom surface of the box body; a detection air duct and a buzzer are arranged on the bottom surface of the box body; the detection air duct is provided with an air inlet and an air outlet which enable air outside the box body to get in and out; dustproof screens, a smoke fog detector and a fan are arranged in the detection air duct in a spacing manner; the dustproof screens are arranged at two ends of the detection air duct to remove dust entering the detection air duct; both the smoke fog detector and the pressure sensor are connected with the buzzer; and the buzzer is connected with a vehicle control system to realize an alarm of a vehicle. The alarm device disclosed by the invention can detect a load capacity and the concentration of smoke fog, and can sound the alarm once the load capacity and the concentration of the smoke fog exceed limited threshold values.

Description

technical field [0001] The design of the invention belongs to the field of electronic technology, in particular to a vehicle alarm. Background technique [0002] At present, the phenomenon of overweight cars is very common. In order to seek more economic benefits, drivers are overloaded and even severely overloaded. The harm of traffic accidents caused by overloaded vehicles is very huge. First, there are serious casualties, and secondly, the damage to highways shortens the normal service life of highways. Even highway bridges need to be overhauled in less than one year. Overloading increases the maintenance cost of tens of billions to hundreds of billions of funds, increasing the cost of highway maintenance. At the same time, the aging of electronic circuits inside the vehicle or the failure of circuit components will have a significant impact on the vehicle and personal safety. When the circuits and components are not completely damaged, although a small amount of smoke m...

Problems solved by technology

The hazards of traffic accidents caused by overloaded vehicles are very great. Firstly, there are serious casualties, and secondly, the damage to the road shortens the normal service life of the road, and even the road bridge needs to be overhauled in less than one year. Overloading increases maintenance costs ranging from tens of billions to hundreds of billions of funds, increasing road maintenance costs

At the same time, the aging of electronic circuits inside the vehicle or the failure of circuit components will have a major impact on vehicle and personal safety. When the circuits and components are not completely damaged, although a small amount of smoke may be generated, due to the low smoke concentration, the driver Often cannot be detected through the sense of smell for the first time
