Description

In-vehicle environment monitoring system

The present invention relates to a monitoring system that can detect various environmental values in a vehicle, and provide warnings and notifications to avoid danger in the vehicle.

At present, more and more attention is paid to the safety of vehicles. For example, the new patent case No. M592838 "Drinking and Driving Detection Device" announced on April 1, 2019 by the Republic of China. It discloses: a device that can be used to detect whether the alcohol concentration of driving in a car exceeds the standard, and has the function of preventing the replacement of the alcohol test. It is provided with a body, and the body includes: a control module, a wireless communication module, and an alcohol sensing module. , relay modules, warning lights and alarms; a plurality of terminals are attached on the back of the body to facilitate the connection of external door sensors, window sensors, pressure sensing modules and car starting devices. The vehicle drunk driving detection device uses a control module for data collection, transmission and control. The alcohol sensor module detects whether the alcohol concentration of driving exceeds the standard; the pressure sensor module is used to detect whether the driver is seated; the door sensor is used to detect whether the door is closed; the window sensor is used to detect whether the window is not closure. When the driver's alcohol concentration does not exceed the standard and each sensor is in normal condition, the car start switch can be used to start the car start device; when the driver's alcohol concentration exceeds the standard, the control module will activate the alarm and warning light to remind the driver. If the driver wants to use the car start switch directly, the car start device will not respond at this time, so as to prevent the occurrence of drunk driving, to ensure the safety of the life and property of drivers and pedestrians, and to achieve the purpose of safe driving.

The previous patent case only provides safety precautions against drunk driving, but lacks protection for other dangerous items.

There is also a patent case of the new type of "driving safety monitoring device" No. M593545 announced on April 11, 109, which discloses that it includes a human motion detector, an air quality detector, an alarm, and A microprocessor, the human motion detector, the air quality detector, and the alarm are respectively connected with the microprocessor: the human motion detector is used to detect the driver's hand motion and send an induction signal ; The air quality detector is used to detect the concentration of carbon dioxide and send out an induction signal; the alarm can receive a control signal and issue an alarm sound; the microprocessor is used to receive the induction signals, and then transmit a control signal after calculation Signal. When in use, if the driver's hand does not move within a certain period of time, the human motion detector sends a sensing signal to the microprocessor, and the microprocessor sends a control signal to make the alarm sound. And remind the driver to concentrate on driving.

Although the previous case of the patent has functions such as detecting the air quality in the car, it does not provide protection against infants and young children locked in the car without being detected. Therefore, infants and young children are often suffocated by heat and regret it. Or someone commits suicide by burning charcoal in the car, but it is still impossible to prevent it, so it is not ideal for use.
