Problems solved by technology

This method requires manual intervention and is only applicable to some people, but it cannot be opened actively for infants or pets
In addition, existing vehicles generally do not have the real-time monitoring function of carbon dioxide. When the concentration of carbon dioxide is too high, it is easy to cause the driver to lose concentration and cause traffic accidents. When infants or pets are trapped in the car, it is easy to Carbon dioxide poisoning and even death from suffocation

Embodiment 1

[0044] The invention relates to a carbon dioxide concentration control system in a car, which is used to control the carbon dioxide concentration in the car to be within a concentration range suitable for the physical and mental health of the human body, so as to prevent the physical and mental health of the people in the car from being affected by the excessive carbon dioxide concentration. The control system mainly includes control unit, carbon dioxide monitoring unit, alarm unit and air conditioning control unit.

[0045] Among them, the control unit can adopt the main controller installed on the vehicle in the prior art, which can constitute the monitoring of the start-stop state of the vehicle engine, and output the engine start-stop signal; the carbon dioxide monitoring unit specifically adopts a carbon dioxide sensor, and its design In the compartment to monitor the carbon dioxide concentration in the compartment, a first carbon dioxide concentration threshold and a seco...

Embodiment 2

[0055] This embodiment relates to a method for controlling carbon dioxide concentration in a vehicle compartment. Based on the system for controlling carbon dioxide concentration in a vehicle compartment described in Embodiment 1, the method includes:

[0056] s1. When the vehicle engine is turned on, the main controller monitors the engine start and stop status, and outputs the engine start signal to the alarm and the controller;

[0057] s1.1. The carbon dioxide sensor monitors the carbon dioxide concentration in the compartment. If the carbon dioxide concentration in the compartment reaches the first carbon dioxide concentration threshold, it outputs a monitoring signal to the alarm to make the alarm perform an alarm. At the same time, the relay starts the alarm timer at the first time, and when When the timing time reaches the first time threshold, a monitoring signal is output to the alarm so that the alarm stops alarming;

[0058] s1.2. The carbon dioxide sensor continue...

Abstract

The invention relates to a carriage carbon dioxide concentration control system and a control method. The compartment carbon dioxide concentration control system comprises a control unit, a carbon dioxide monitoring unit, an alarm unit and an air conditioner control unit. The control unit can monitor a start-stop state of a vehicle engine, a first carbon dioxide concentration threshold value and asecond carbon dioxide concentration threshold value are preset in a carbon dioxide concentration monitoring unit, and the carbon dioxide monitoring unit can output corresponding monitoring signals due to a fact that a monitored carbon dioxide concentration is matched with different carbon dioxide concentration threshold values. According to the carriage carbon dioxide concentration control system, when the monitored carbon dioxide concentration is matched with the first carbon dioxide concentration threshold value and the second carbon dioxide concentration threshold value, the correspondingmonitoring signals are output to the alarm unit and the air conditioner control unit respectively so that dual functions of manual control and automatic control can be fully played, and a control effect on the concentration of carbon dioxide in a carriage can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle compartment carbon dioxide concentration control system, and at the same time, the invention also relates to a compartment carbon dioxide concentration control method. Background technique [0002] In order to ensure the effect of cooling, heating and low noise in the compartment, the existing vehicles generally have good airtightness, which also makes it difficult for the air in the compartment to circulate, so that when the concentration of carbon dioxide in the compartment reaches a certain value, it is easy to Affect the physical and mental health of the occupants, and even threaten life safety. [0003] At present, when the occupants feel uncomfortable in the car, they usually actively turn on the external circulation of the air conditioner to reduce the concentration of carbon dioxide in the car. This method requires manual intervention and is only applic...
