detailed description

The present invention will be further described below in conjunction with the drawings and specific embodiments.

Referring to FIG. 1, an automobile safety monitoring method provided by the present invention includes the following steps:

Step S101, real-time monitoring of the automobile exhaust gas at the exit of the automobile exhaust gas purifier, and analyzing the automobile exhaust gas to obtain the types and contents of various harmful gases in the automobile exhaust gas.

In one of these embodiments, multiple gas detectors can be utilized to detect vehicle exhaust. Each gas detector can detect the type and content of harmful gases contained in the exhaust gas.

In another embodiment, the exhaust gas at the outlet of the automobile exhaust gas purifier is inspected. The process of testing may include the following steps:

Inspecting the vehicle exhaust at the exit of the automobile exhaust gas purifier by means of infrared detection;

Generating a corresponding electrical signal according to the wavelength range of the absorbed infrared light and the degree of absorption;

The electrical signal is amplified and filtered, and the types and contents of various harmful gases are obtained according to the filtered electrical signal.

Since automobile exhaust gas usually contains various harmful gases such as carbon monoxide, hydrocarbons, sulfur oxides, and nitrogen oxides. Each of these gases has a specific characteristic absorption band and characteristic frequency that is strongly absorbed when the infrared spectrum falls near the characteristic frequency band. Therefore, the infrared spectrum of the corresponding characteristic frequency can be used to detect the components of the harmful gas in the exhaust gas, and the amount of the external spectrum absorbed can detect the type and content of the corresponding gas, and all kinds of harmful gases can be calculated according to the type and content of various harmful gases. The total amount of harmful gas emissions.

Step S102: Determine whether the total amount of harmful gas emissions in the automobile exhaust exceeds a first threshold according to the type and content of the harmful gas. If yes, step S103 is performed. Otherwise, the process returns to step S101 to perform exhaust gas monitoring.

Step S103, if the result of the determination in step S102 is YES, obtain the current traveling speed of the automobile and the temperature inside the vehicle compartment, and pass when the current traveling speed of the automobile is less than the second threshold and the temperature in the automobile compartment is greater than the third threshold. The car's electronic control system issues instructions to control the closing of all car side windows and automatically open the car air conditioner and the car sunroof.

In the embodiment of the present invention, when the total amount of harmful gas emissions exceeds the standard, The front driving speed is used to judge whether the vehicle is currently in a traffic jam state. In consideration of the traffic jam state, the passenger generally selects the taxi side window to observe the traffic environment.
