Specifically, in order to prevent the problem that the vehicle cannot be started due to the drinking of the passenger, which affects the running of the vehicle, the apparatus is provided with an alcohol detection switch 100; the alcohol detection switch 100 is electrically connected with the alcohol detection module 200 and is used for controlling the alcohol detection module 200 to be turned on and off; after vehicles such as vehicles or ships and the like are powered on, a driver selects whether the alcohol detection module 200 is started or not, if the alcohol detection switch 100 is pressed, the alcohol detection module 200 is controlled to be started so as to carry out alcohol detection, otherwise, the alcohol detection module 200 is in a closed state and does not carry out alcohol concentration detection so as to prevent the phenomenon that the alcohol detection exceeds a first threshold value and causes the vehicles or ships and the like to be incapable of being started or the accurate value of the alcohol concentration causes the alarm of the vehicles or the ships between the first threshold value and a second threshold value due to the fact that a passenger drinks, so that the driver only needs to select not to press the alcohol detection switch 100 to cancel the alcohol concentration detection of the alcohol detection module 200 when the passenger drinks. After the alcohol detection module 200 is started, it performs one-time alcohol concentration detection on the alcohol gas to be detected at preset intervals in a total preset time period to obtain at least one alcohol concentration detection value, where the alcohol gas to be detected may be the gas blown out by a driver, and certainly may also be the gas blown out by other people to be detected; the total preset time period and the preset time can be determined according to actual conditions so as to obtain a certain amount of alcohol concentration detection value; the alcohol concentration detection module 200 may be an alcohol concentration sensor; to ensure that the alcohol concentration tested is the driver's own alcohol concentration to improve the accuracy of alcohol detection, the alcohol detection module 200 is disposed closest to the driver's location, for example, the alcohol detection module 200 is disposed on the steering wheel of a vehicle or a ship.

Specifically, the control module 600 is electrically connected to the alcohol detection module 200, and is configured to receive an alcohol concentration detection value obtained by the alcohol detection module 200, and calculate an alcohol concentration accurate value according to the alcohol concentration detection value, where the control module 600 may select a processor such as a single chip microcomputer; in order to improve the efficiency of the control module 600 in calculating the accurate value of the alcohol concentration, the control module 600 is electrically connected with the control module 600 through the analog-to-digital conversion module 300, so that the alcohol concentration obtained by the alcohol detection module 200 is converted into a digital signal through the analog-to-digital conversion module 300 and is sent to the control module 600; to ensure the accuracy of the accurate value of the alcohol concentration, the control module 600 may preferably select the largest ones of the detected values of the alcohol concentration to obtain the accurate value of the alcohol concentration; the control module 600 compares the accurate value of the alcohol concentration with a first threshold and a second threshold, and sends out a blocking signal when the accurate value of the alcohol concentration is greater than or equal to the first threshold, and sends out an alarm signal when the accurate value of the alcohol concentration is less than the first threshold and greater than or equal to the second threshold; according to the regulations of blood and breath alcohol content threshold and inspection of vehicle drivers (GB 19522-2004) issued by the State quality supervision, inspection and quarantine bureau, the driver drives after drinking when the alcohol content in every 100ml of blood is more than or equal to 20mg and the alcohol content in every 100ml of blood is less than 80mg, and drives drunk when the alcohol content in every 100ml of blood is more than or equal to 80 mg; according to traffic safety, preferably, the first threshold may be 80mg/100ml and the second threshold may be 20mg/100ml, that is, the control module 600 may issue the blocking signal when the driver is in the drunk state and issue the blocking signal when the driver is driving after drinking. The execution module 700 is electrically connected with the control module 600 and is used for receiving a blocking signal and an alarm signal; the execution module 700 gives an alarm and simultaneously gives a blocking signal when receiving the blocking signal; the blocking action can be the prevention of the starting of a vehicle or a ship, or other actions for preventing the driver from driving, such as the automatic deviation of a seat to prevent the driver from driving, and the like; the alarm is given when an alarm signal is received, wherein the alarm can be given in various ways, such as a buzzer sound and a flashing lamp.
Obviously, in the alcohol detection control device provided in this embodiment, the alcohol concentration detection module 200 is used to detect the alcohol concentration of the driver, the control module 600 is used to receive the alcohol concentration detection value obtained by the alcohol detection module 200, and different signals are sent according to the comparison result after the alcohol concentration detection value is compared with the first threshold and the second threshold, and the execution module 700 is used to alarm or block in different ways according to the signals sent by the control module 600, so that the alarm can warn the driver that the alcohol drinking exceeds the standard to remind the driver not to drive after drinking; meanwhile, the execution module 700 performs the blocking action to prohibit the driver from driving after drinking so as to prevent the drunk driving phenomenon and further reduce the occurrence of safety accidents caused by drunk driving.
With continued reference to fig. 1, to improve the accuracy of the control module 600 in calculating an accurate value of alcohol concentration, the apparatus further comprises: a pressure detection module 400 and a temperature detection module 500; the pressure detection module 400 is configured to obtain a pressure of the alcohol gas to be detected when the alcohol detection module 200 obtains an alcohol concentration detection value, and the control module 600 is electrically connected to the pressure detection module 400, and is further configured to receive the pressure obtained by the pressure detection module 400 and correct the received alcohol concentration detection value according to the pressure; the temperature detection module 500 is configured to obtain a temperature of the alcohol gas to be detected when the alcohol detection module 200 obtains an alcohol concentration detection value, and the control module 600 is electrically connected to the temperature detection module 500, and is further configured to receive the temperature obtained by the temperature detection module 500 and correct the received alcohol concentration detection value according to the temperature.
Specifically, while the alcohol detection module 200 detects the alcohol concentration of the driver, that is, obtains the alcohol concentration detection value, the pressure detection module 400 detects the pressure of the alcohol gas to be detected so as to obtain the pressure of the alcohol gas to be detected, the temperature detection module 500 detects the temperature of the alcohol gas to be detected so as to obtain the temperature of the alcohol gas to be detected, and the pressure and the temperature are in one-to-one correspondence with the alcohol concentration detection value obtained by the alcohol detection module 200; in order to improve the detection accuracy, the pressure detection module 400 and the temperature detection module 500 may be a pressure sensor and a temperature sensor, respectively; the control module 600 is further configured to receive the pressure obtained by the pressure detection module 400 and the temperature obtained by the temperature detection module 500, and correct the received alcohol concentration detection value according to the temperature and the pressure, so that the control module 600 calculates an accurate alcohol concentration value according to the corrected alcohol concentration detection value.
In order to prevent the detection that the alcohol concentration of the air blown out is affected by insufficient pressure of the air blown out when the driver detects the air concentration, the control module 600 can judge whether the received alcohol concentration detection value is accurate according to whether the pressure obtained by the pressure detection module 400 reaches the standard or not when the alcohol concentration is detected, and when the pressure obtained by the pressure detection module 400 is added to be smaller than a standard pressure value, the temperature and the alcohol concentration detection value corresponding to the pressure are deleted when the alcohol concentration accurate value is calculated, so that the influence on the calculation of the accurate value of the alcohol concentration is avoided, and the alcohol concentration detection value received by the control module 600 is corrected.
As is well known to those skilled in the art, the alcohol detection module 200 has a certain sensitivity to the temperature in the environment, and when the temperature of the air in the cab decreases, the alcohol detection module 200 generates linear distortion to the alcohol concentration along with the decrease of the temperature, thereby causing the accuracy of the detection result to decrease; in order to further improve the accuracy of the control module 600 in calculating the accurate value of the alcohol concentration, the temperature detection module 500 performs temperature detection on the alcohol gas to be detected; the control module 600 determines whether the alcohol concentration detection value obtained by the alcohol detection module 200 is accurate according to the temperature obtained by the temperature detection module 500, and can compare the temperature with a standard temperature value, and if the temperature is smaller than the standard temperature value, delete the pressure and the alcohol concentration detection value corresponding to the temperature when calculating the alcohol concentration accurate value so as to avoid the influence on the calculation of the alcohol concentration accurate value, and further correct the alcohol concentration detection value received by the control module 600.
It can be obviously obtained that the alcohol detection control device provided in this embodiment detects the pressure of the alcohol gas to be detected through the pressure detection module 400, detects the temperature of the alcohol gas to be detected through the temperature detection module, so as to correct the received alcohol concentration detection value through the control module 600, and further improve the accuracy of calculating the alcohol concentration accurate value, thereby improving the accuracy of the execution module 700 for alarming and blocking, and avoiding the occurrence of the phenomenon that the driver is driven by wine or the vehicle is started by the driver is influenced.
With continued reference to fig. 1, the alcohol detection module 200 is an electrochemical alcohol sensor.
Specifically, the alcohol detection module 200 may be an alcohol sensor; as is well known in the art, alcohol sensors mainly include semiconductor-type alcohol sensors and electrochemical alcohol sensors (also called fuel cell-type alcohol sensors); the electrochemical alcohol sensor is provided with a special catalyst in a combustion chamber, and the catalyst can only enable alcohol gas to be detected entering the combustion chamber to be fully combusted and converted into electric energy to be output, namely, the selection pertinence is strong, and no reaction is generated on other non-alcohol gases; the resistance value of the semiconductor type alcohol sensor changes in relation to the concentration of the first-order non-alcohol gas. The response time of the electrochemical alcohol sensor is as short as about 0.5s, and the response time of the electrochemical alcohol sensor does not change along with the aging of the device; the response time of the brand-new semiconductor type alcohol sensor is about 5s at the fastest speed, and the response time of the brand-new semiconductor type alcohol sensor is gradually prolonged by a period of time, which is about half a minute. The output current of the electrochemical alcohol sensor is in direct proportion to the concentration of alcohol gas sucked into the combustion chamber, the metering accuracy is very high, and the conversion rate of the electrochemical alcohol sensor is only influenced by the ambient temperature of the fuel cell; the resistance value change of the semiconductor type alcohol sensor is related to the temperature and the concentration of non-alcohol gas, so that the resistance value change is limited during measurement, the interference of other gas on a test result and the interference degree can not be eliminated, and the error of the test result is larger when the alcohol concentration is too high or too low. Therefore, the accuracy of the device for detecting the alcohol concentration can be improved by using the electrochemical alcohol sensor; the electrochemical alcohol sensor outputs a current signal, calculates the alcohol concentration of the alcohol gas to be detected, i.e., an alcohol concentration detection value, according to the magnitude of the current in the current signal, and converts the current signal of the electrochemical alcohol sensor into a digital signal through the analog-to-digital conversion module 300 and then sends the digital signal to the control module 600 for calculation.
Obviously, it can be understood that the alcohol detection module 200 provided in the present embodiment implements detection of alcohol concentration by an electrochemical alcohol sensor; compared with a semiconductor type alcohol sensor, the electrochemical alcohol sensor has short response time, does not change along with the aging of components and parts, and is slightly influenced by the external environment, so the electrochemical alcohol sensor further improves the accuracy of the device for detecting the alcohol concentration.

Specifically, in order to perform a blocking action to prevent the vehicle from starting, the blocking unit 710 is electrically connected to a switching circuit of the vehicle, and the blocking unit 710 receives a blocking signal transmitted by the control module 600 and blocks the switching circuit so as to prevent the vehicle from starting; of course, the blocking unit 710 may also be electrically connected to the engine control circuit, and control whether the engine is normally started by controlling the operating state of the engine control circuit, so as to control the starting of the vehicle. The alarm unit 720 is electrically connected with the control module 600 and is used for receiving the blocking signal and the alarm signal, and the alarm signal 720 gives an alarm when receiving the blocking signal or the alarm signal so as to remind the driver not to drive after drinking.
It is obviously understood that, the execution module 700 provided in this embodiment performs the blocking action through the blocking unit 710 when receiving the blocking signal so as to prevent the occurrence of the drunk driving phenomenon, and performs the alarm through the alarm unit 720 when receiving the alarm signal, and both of them are implemented separately, and the structure is simple and easy to implement.

Specifically, when receiving the blocking signal or the alarm signal, the alarm lamp 721 lights or continuously flashes to remind the person not to drive after drinking; the voice announcer 722 prompts the driver not to drive after drinking by voice announcement when receiving the blocking signal or the alarm signal, and may prompt the driver not to drive after drinking by different voice announcers when receiving the blocking signal or the alarm signal, for example, may play voice announcement "alcohol concentration detection is drunk driving, the vehicle is prevented from starting" when receiving the blocking signal, "alcohol concentration detection is drunk driving, do not drive after drinking" when receiving the blocking signal, so as to remind the driver and the passenger.
It can be obviously understood that the alarm unit 720 provided in this embodiment prompts the person not to drive after drinking through the lamp of the alarm lamp 721 being on or continuously flashing and/or through the voice broadcast of the voice broadcaster 722, thereby reducing the possibility of the person driving after drinking and reducing the danger caused by the driving after drinking.
In summary, in the alcohol detection control apparatus provided in this embodiment, the alcohol concentration detection module 200 detects the alcohol concentration of the alcohol gas to be detected, the control module 600 receives the alcohol concentration detection value obtained by the alcohol detection module 200, and sends different signals according to the comparison result after comparing the alcohol concentration detection value with the first threshold and the second threshold, and the execution module 700 gives an alarm or performs a blocking action in different manners according to the signal sent by the control module 600, so that the alarm can warn the driver that alcohol drinking exceeds the standard to remind the driver not to drive after drinking; meanwhile, the execution module 700 performs the blocking action to prohibit the driver from driving after drinking so as to prevent the drunk driving phenomenon and further reduce the occurrence of safety accidents caused by drunk driving.
In particular, the alcohol detection control device provided in this embodiment controls the start and the stop of the alcohol detection module 200 through the alcohol detection switch 100, so as to avoid the phenomenon that the alcohol detection exceeds the first threshold value due to the drinking of the passenger, so that the vehicle cannot be started or the alarm is caused when the accurate value of the alcohol concentration is between the first threshold value and the second threshold value.
Further, the alcohol detection control device provided in this embodiment detects the pressure of the alcohol gas to be detected through the pressure detection module 400, detects the temperature of the alcohol gas to be detected through the temperature detection module, so as to correct the alcohol concentration detection value received by the control module 600, and further improve the accuracy of calculating the alcohol concentration accurate value, thereby improving the accuracy of alarming and blocking actions performed by the execution module 700, and avoiding the phenomenon that the driver is drunk or the vehicle is started by the driver is influenced.
The embodiment of the vehicle is as follows:
