95 results about "Car alarm" patented technology

A car alarm is an electronic device installed in a vehicle in an attempt to discourage theft of the vehicle itself, its contents, or both. Car alarms work by emitting high-volume sound (often a vehicle-mounted siren, klaxon, pre-recorded verbal warning, the vehicle's own horn, or a combination of these) when the conditions necessary for triggering it are met. Such alarms may also cause the vehicle's headlights to flash, may notify the car's owner of the incident via a paging system, and may interrupt one or more electrical circuits necessary for the car to start. Although inexpensive to acquire and install, the effectiveness of such devices in deterring vehicle burglary or theft when their only effect is to emit sound appears to be negligible.

Automatic car alarm based on in-car temperature and gas detection

The invention provides an automatic car alarm based on in-car temperature and gas detection. The automatic car alarm based on in-car temperature and gas detection comprises a housing and a host in the housing. The host comprises a central processing unit, and further comprises a storage, an in-car gas environment measuring module, a communication and alarm module, a data input module, a GPS locating module, an infrared induction module, a power supply module and a storage battery which are connected with the central processing unit. The infrared induction module inducts whether a person stays inside a car or not, and transmits induction data to the central processing unit. The central processing unit analyzes whether the in-car gas environment measuring module is opened or not according to the data. The in-car gas environment measuring module detects parameters of O2, CO, CO2 and temperature in the car. The central processing unit enables the parameters detected by the in-car gas environment measuring module to be compared with alarm situation parameters prestored in the storage, and the alarm situation is controlled to be fed back to a car owner based on the comparison result. By the automatic car alarm based on in-car temperature and gas detection, based on the condition whether a person stays inside the car or not, the parameters of O2, CO, CO2 and temperature in the car are detected automatically, and an alarm is given automatically when a person feels uncomfortable.

Car door opening bidirectional prompting system

The invention provides a car door opening bidirectional prompting system, consisting of a car door switch, an external car alarm, an ultrasonic speed measurement module, an internal car alarm, a car tail camera and a car door display screen. The external car alarm, the ultrasonic speed measurement module, the internal car alarm, the car tail camera and the car door display screen are connected on the car door switch; the car door switch is connected with a handle at the inner side of a card door; and the handle at the inner side of the card door is opened, so that the corresponding car door switch is switched on; when the car door switch is switched off, the external car alarm, the ultrasonic speed measurement module, the internal car alarm, the car tail camera and the car door display screen enter a working state simultaneously. When the car door is opened, the car door opening bidirectional prompting system can prompt pedestrians and vehicles passing the side; and meanwhile, a person opening the car door catches the sight of the condition in back of the vehicle. If an object moving to the vehicle is detected in back of the vehicle, the person opening the car door is prompted, so as to effectively avoid personal casualty accidents caused by the situation that the pedestrians and the vehicles run into the opened car door or a driver or a passenger getting off the car.

Intelligent rescue system capable of detecting carbon dioxide concentration in car

An intelligent rescue system capable of detecting the carbon dioxide concentration in a car comprises a central controller, a cloud side, a guardian side and a car alarm side and further comprises a carbon dioxide sensor. The carbon dioxide sensor is connected with the central controller; when the car is turned off and a car door is closed, the central controller drives the carbon dioxide sensor to collect the carbon dioxide concentration and starts the carbon dioxide sensor again at preset time to make the carbon dioxide sensor collect the carbon dioxide concentration. The central controller is connected with a car door locking circuit and an in-car signal side and compares signals transmitted by the carbon dioxide sensor; when the difference value of the carbon dioxide concentration reaches a preset range value, the central controller starts the car alarm side and the in-car signal side and transmits in-car data collected by the in-car signal side to the cloud side. The intelligent rescue system is used for dealing with the situation that a child is locked in the car; because the space in the car is an airtight environment, whether the child exists in the car or not can be judged according to the carbon dioxide concentration or oxygen concentration in the car, and then the car alarm side or the guardian side is triggered to give an alarm.
