Although this patent judges the car running state through the controller, to carbon monoxide content real-time detection and control in the car to take corresponding measure through alarm device, car loudspeaker control module, door window control module and wireless communication module, can avoid personnel's carbon monoxide poisoning in the car to a certain extent.
However, the carbon monoxide sensor is required to detect the concentration of toxic gas in the vehicle, and an alarm is given when the concentration is too high, or a window is opened. And if set up a carbon monoxide sensor, then detect not comprehensive enough, it is more then can the problem to set up a plurality of, and firstly the little mounted position in car space is not enough, installs inconvenient in addition and also needs additionally to increase more costs. Even set up a plurality of carbon monoxide sensors simultaneously, the condition that also appears detecting the inefficacy easily, if under the condition of windowing, the inside and outside air part of car of carbon monoxide sensor department exchanges, and it is very high to cause carbon monoxide sensor department not to detect toxic gas's concentration, but the human body is just in the place that toxic gas is higher in the car to make the sensor detect the inefficacy, consequently prevent the scheme validity of poisoning to vehicle idle among the prior art and be not high.

Detailed Description
The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1, a control method for preventing vehicle from being poisoned during idling includes the following steps:
judging whether to start anti-poisoning control: when the vehicle is started and the vehicle speed is less than the vehicle speed threshold value, the controller 3 judges that the vehicle is idling and enters anti-poisoning control, otherwise, the anti-poisoning control is not entered. When the vehicle is started and the vehicle speed is less than the vehicle speed threshold value, the vehicle is indicated to be idle, personnel in the vehicle have poisoning risks, the vehicle enters anti-poisoning control at the moment, and when the vehicle is started and the vehicle speed is less than the vehicle speed threshold value, the vehicle does not idle and does not enter the anti-poisoning control. The vehicle speed threshold value ranges from 5km/h to 10km/h, and is preferably 5 km/h.
In this embodiment, a control switch 16 for controlling the start and the stop of the anti-poisoning control is provided, and a setting is added to the condition of entering the anti-poisoning control, specifically, when the vehicle is started and the control switch 16 is in the anti-poisoning control start state and the vehicle speed is less than the vehicle speed threshold, the controller 3 enters the anti-poisoning control, and the control switch 16 exits the anti-poisoning control when the anti-poisoning control is controlled to be closed.
And (3) poisoning prevention control: the timing module 4 starts timing, when the signal that the vehicle is operated is not received in the timing process and the current timing time is greater than the timing threshold value one and less than the timing threshold value two, the controller 3 controls the alarm module 2 to send out an anti-poisoning alarm, when the signal that the vehicle is operated is not received in the timing process and the current timing time is greater than the timing threshold value two, the controller 3 controls the vehicle to flameout, and the vehicle quits the anti-poisoning control after flameout. The timing module 4 indicates that the personnel in the vehicle may be in a rest state when not receiving the signal that the vehicle is operated after the timing is started, and sends out an anti-poisoning alarm to remind the personnel in the vehicle of poisoning risk when the timing threshold value one is smaller than the timing threshold value two, the personnel in the vehicle can operate the vehicle after receiving the poisoning alarm to enable the controller 3 to judge whether to enter anti-poisoning control again, if the personnel in the vehicle does not operate the vehicle within the period of time that the timing threshold value two is greater after the anti-poisoning alarm is sent out, the personnel in the vehicle may not be in a wake-up state when the timing is greater than the timing threshold value two, and the vehicle is controlled to be flameout.
The first timing threshold ranges from 6 to 10 minutes, as the preferred first timing threshold is 8 minutes, the second timing threshold ranges from 7 to 11 minutes, as the preferred second timing threshold is 10 minutes.
And when the timing module 4 starts timing, the timing time is less than or equal to the timing threshold value two and a signal that the vehicle is operated appears, whether anti-poisoning control is started or not is judged again. After the anti-poisoning control is started, if the vehicle is operated to indicate that the vehicle interior person is in a waking state, and if the concentration of the toxic gas is high when the vehicle interior person is in the waking state, the vehicle interior person can sense the toxic gas, so that the vehicle is indicated that the vehicle interior person is in a waking state when the vehicle is operated, whether the anti-poisoning control is started or not is judged again, and the anti-poisoning control is started when the anti-poisoning control condition is met.
The signals for operating the vehicle comprise a brake switch 8 state jump signal, a clutch state jump signal, a gear state jump signal, an outside vehicle lamp switch 11 state jump signal, a wiper switch 12 state jump signal, a window glass lifting switch 13 state jump signal, a vehicle door state jump signal and a lock switch 15 state jump signal. And generating corresponding jump signals through the operation of the devices, wherein the vehicle is operated as long as one item in the jump signals is received. Whether personnel operate the vehicle in the car is comprehensively detected through the setting, and after the personnel in the car are reminded of having poisoning risks, the personnel in the car can randomly select an operation to indicate that the personnel in the car are awake, so that the personnel in the car can conveniently have a rest. The signal to operate the vehicle may also add a detection switch depending on the conditions set inside the vehicle. The jump signal indicates that the output signal changes, if the brake switch 8 is turned on, the brake switch 8 is turned on after the brake is operated, the signal jumps, and if the window glass lifting switch 13 is pressed to lift or lower the window glass, the state of the window glass lifting switch 13 changes to generate the signal jumps. The controller 3 determines whether or not the corresponding device is operated by the signal, thereby determining whether or not the vehicle is operated.
And in the anti-poisoning control process, judging whether to start anti-poisoning control again when the vehicle speed is greater than the vehicle speed threshold value. When the vehicle speed is greater than the vehicle speed threshold value, the vehicle is indicated to be driven, namely the vehicle is also indicated to be operated, the accuracy of detecting the operation of the vehicle is improved, the anti-poisoning control is quitted, and whether the anti-poisoning control is to be continuously entered or not is continuously judged.
As shown in FIG. 2, the control system for preventing the vehicle from being poisoned by the idling is applied to the control method. The control system for preventing the poisoning of the automobile in the idling process comprises an ignition switch 1, an alarm module 2, a controller 3 with a timing module 4 inside and a relay 5 for controlling the power supply of the whole automobile to be switched to a closed state so as to enable the automobile to be flamed out.
