Description

车载导航设备、车载酒后驾驶检测装置及方法、 汽车安全驾驶服务***及方法  Vehicle navigation device, vehicle drunk driving detection device and method, automobile safety driving service system and method 技术领域Technical field
本发明涉及汽车安全行驶技术，更具体地说，涉及一种能够识别驾驶员酒后驾车并自动语音提示的车载导航设备、车载酒后驾驶检测装置及方法、以及汽车安全驾驶服务***及方法。 The present invention relates to a safe driving technique for automobiles, and more particularly to an in-vehicle navigation device capable of recognizing a driver's drunk driving and automatic voice prompting, an in-vehicle drunk driving detecting device and method, and a car safe driving service system and method.
背景技术Background technique
酒后驾驶是导致交通事故的一个重要原因，因此对驾驶员是否饮酒过量进行检测就显得十分重要。目前，检测驾驶员是否饮酒过量的主要方法是由交通警察使用安装有二氧化锡半导体元件的手持式酒精浓度检测仪直接检测驾驶员呼出的气体。在检测过程中，要求使用者对着检测仪的呼气管呼气，持续时间超过三秒钟。二氧化锡半导体对空气中的酒精十分敏感，其电阻会随空气中酒精浓度的变化而变化。安装有二氧化锡半导体元件的监测仪就是基于这一原理，通过测定该元件两端的电压的变化来检测电阻的变化，从而得到驾驶员呼出空气中的酒精浓度。Drinking and driving is an important cause of traffic accidents, so it is very important to check whether the driver is drinking too much. At present, the main method for detecting whether the driver is drinking too much is to directly detect the gas exhaled by the driver by the traffic police using a hand-held alcohol concentration detector equipped with a tin dioxide semiconductor component. During the test, the user is required to exhale the expiratory tube of the tester for more than three seconds. Tin dioxide semiconductors are very sensitive to alcohol in the air, and their electrical resistance changes with the concentration of alcohol in the air. Based on this principle, a monitor equipped with a tin dioxide semiconductor component detects a change in resistance by measuring a change in voltage across the component, thereby obtaining a concentration of alcohol in the air exhaled by the driver.
然而，上述检测酒精浓度的方法存在很多弊端，其主要表现在，上述检测方法的具体应用主要是一种手持酒精浓度检测仪，其应用领域主要集中在交通管理部门对驾驶员酒后驾车行为的监督管理。在实施时，由执勤交通警察手动检测目标车辆驾驶员是否饮酒过量。但手动检测无法在驾驶员起动车辆时立即开始检测，而只能在行驶过程中首先叫停车辆，再对驾驶员进行检测。因此现有技术无法将酒后驾车消除在萌芽阶段。此外，与驾驶员有关的人（如亲属、公司主管）也需要实时了解驾驶员是否酒后驾车，并且希望在得知驾驶员酒后驾车行为后能够立即获取其当前位置及行驶方向等信息，进而采取相应的应对措施。而上述检测方法无法实现这一目的。However, the above method for detecting alcohol concentration has many drawbacks, and the main application thereof is that the specific application of the above detection method is mainly a handheld alcohol concentration detector, and its application field mainly focuses on the driver's drunk driving behavior in the traffic management department. Supervise management. At the time of implementation, the duty traffic police manually detects whether the target vehicle driver is drinking excessively. However, the manual detection cannot start the detection immediately when the driver starts the vehicle, but can only stop the vehicle first during the driving process and then detect the driver. Therefore, the prior art cannot eliminate drunk driving in the nascent stage. In addition, the driver-related person (such as relatives, company supervisors) also needs to know in real time whether the driver is drunk driving, and hopes to immediately obtain information such as his current position and driving direction after learning the driver's drunk driving behavior. Then take corresponding countermeasures. The above detection method cannot achieve this purpose.
由此，需要一种酒后驾车检测方案，能够在车辆起动时立即自动检测驾驶员是否酒后驾车及上报当前位置信息，有效降低酒后驾车隐患并在检测到酒后驾车行为后及时采取相应救援措施。
Therefore, a drunk driving detection program is needed, which can automatically detect whether the driver drunk driving and report the current position information immediately when the vehicle starts, effectively reducing the risk of drunk driving and taking corresponding measures after detecting the drunk driving behavior. Rescue measures.

The wireless communication module 120, the positioning module 130, the alcohol detecting module 140, the voice module 144, the speaker 150, and the microphone 160 are respectively connected to the control module 110.
本发明的车载导航设备除了具有传统的导航、搜索路径功能外，还增加了新功能：诸如酒精检测和通信功能。另外，车载导航设备上还可设置显示模块(图中未示出)，以向用户展示导航路径。In addition to the traditional navigation and search path functions, the in-vehicle navigation device of the present invention adds new functions such as alcohol detection and communication functions. In addition, a display module (not shown) may be disposed on the car navigation device to display the navigation path to the user.
抽气风扇142作为优选配置用于将车内驾驶位置附近的气体引导至酒精检测模块中的酒精传感器探头处。在其他实施例中，也可以不配置抽气风扇。The exhaust fan 142 is preferably configured to direct gas in the vicinity of the in-vehicle driving position to the alcohol sensor probe in the alcohol detecting module. In other embodiments, the exhaust fan may not be configured.
定位模块130用于接收卫星导航定位信号，经控制模块110处理后生成定位信息。例如，定位模块130可以用于接收GPS定位***、北斗卫星导航定位或伽俐略（Galileo）卫星导航定位***等的卫星导航定位信号。无线通信模块120可基于无线通信协议(例如GSM、CDMA或GPRS)与远程无线通信设备进行通信(诸如短信和语音通信)，以传送或交互信息。The positioning module 130 is configured to receive a satellite navigation positioning signal, and generate the positioning information after being processed by the control module 110.

根据一个实施例，本发明的具有酒精检测功能的车载导航设备中，控制模块110、无线通信模块120、定位模块130、酒精检测模块140、抽气风扇142、语音模块144、扬声器150和麦克风160及显示模块全部安装在一个机壳上，即酒精检测和无线通信功能集成于传统的车载导航设备上。这种实现方式使得车载导航设备功能更加强大，为用户带来了方便。由于酒精检测模块集成在车载导航设备的机壳上，不用另外单独安装，减少了安装成本，也不会对车内原设施或装饰造成破坏。According to an embodiment, in the car navigation device with alcohol detection function of the present invention, the control module 110, the wireless communication module 120, the positioning module 130, the alcohol detecting module 140, the exhaust fan 142, the voice module 144, the speaker 150 and the microphone 160 And the display module is all installed on one case, that is, the alcohol detection and wireless communication functions are integrated on the traditional car navigation device. This implementation makes the car navigation device more powerful and convenient for the user. Since the alcohol detection module is integrated in the casing of the car navigation device, it is not required to be separately installed, which reduces the installation cost and does not cause damage to the original facility or decoration in the car.
本发明车载导航设备其他部件的功能/作用将在后面结合图2和图3进行详细描述。The function/function of other components of the in-vehicle navigation device of the present invention will be described in detail later with reference to FIGS. 2 and 3.
图2是根据本发明一实施例的具有酒精检测功能的车载导航设备中酒精检测模块的结构示意图。如图2所示，酒精检测模块140包括酒精传感器146和与其相连的信号放大器148，用于检测车内酒精浓度。2 is a schematic structural diagram of an alcohol detecting module in an in-vehicle navigation device having an alcohol detecting function according to an embodiment of the invention. As shown in FIG. 2, the alcohol detection module 140 includes an alcohol sensor 146 and a signal amplifier 148 coupled thereto for detecting the concentration of alcohol in the vehicle.
由于车内密闭空间大，空气中的酒精浓度较低，一般的传感器结构很难检测到空气中的酒精含量。在本发明的优选实施例中，通过抽气风扇，将车内气流引导至酒精传感器的探头附近，再由信号放大器将酒精传感器检测到的微弱信号放大，再将放大后的信号后交由控制模块进行处理。Due to the large confined space in the car and the low alcohol concentration in the air, it is difficult to detect the alcohol content in the air in the general sensor structure. In a preferred embodiment of the present invention, the airflow in the vehicle is guided to the vicinity of the probe of the alcohol sensor by the exhaust fan, and then the weak signal detected by the alcohol sensor is amplified by the signal amplifier, and then the amplified signal is then subjected to control. The module processes it.
图3是根据本发明一实施例的具有酒精检测功能的车载导航设备中控制模块的结构示意图。如图3所示，控制模块110包括处理器112、采样模块114、存储器116、及接口模块118。其中，处理器112包括判断模块112a，接口模块118包括定位模块接口118a、通信模块接口118b、语音模块接口118c、音频I/O接口118d及显示模块接口118e。3 is a schematic structural diagram of a control module in an in-vehicle navigation device having an alcohol detecting function according to an embodiment of the invention. As shown in FIG. 3, the control module 110 includes a processor 112, a sampling module 114, a memory 116, and an interface module 118. The processor 112 includes a determining module 112a. The interface module 118 includes a positioning module interface 118a, a communication module interface 118b, a voice module interface 118c, an audio I/O interface 118d, and a display module interface 118e.
采样模块114用于从所述酒精检测模块接收酒精浓度信息；存储器116用于存储酒精浓度超标的浓度阈值；判断模块112a用于根据酒精浓度信息及浓度阈值通过比较确定酒精浓度是否超过浓度阈值。在一个实施例中，当确定酒精浓度超过预定酒精浓度时，控制模块通过语音模块接口118c发送触发信号至语音模块，驱动语音模块输出语音信号至扬声器9(例如输出提醒司机“请不要酒后驾车”的语音)。在另一个实施例中，控制模块在对酒精浓度信息分析、判断后通过语音提示酒精浓度高低。在又一个实施例中，如果酒精浓度超标，控制模块通过语音模块接口118c发送触发信号至语音模块，同时通过通信模块接口118b发送报警信息和定位信息至通信模块，以向外发送这。The sampling module 114 is configured to receive alcohol concentration information from the alcohol detecting module; the memory 116 is configured to store a concentration threshold of the alcohol concentration exceeding the standard; and the determining module 112a is configured to determine, according to the alcohol concentration information and the concentration threshold, whether the alcohol concentration exceeds the concentration threshold. In one embodiment, when it is determined that the alcohol concentration exceeds the predetermined alcohol concentration, the control module sends a trigger signal to the voice module through the voice module interface 118c, and drives the voice module to output a voice signal to the speaker 9 (eg, outputting an alert driver "Please do not drunk driving "The voice." In another embodiment, the control module promptly indicates the alcohol concentration by voice after analyzing and judging the alcohol concentration information. In still another embodiment, if the alcohol concentration exceeds the standard, the control module sends a trigger signal to the voice module through the voice module interface 118c, and simultaneously sends the alarm information and the location information to the communication module through the communication module interface 118b to transmit the outward.
在本发明的实施例中，控制模块可以使用单片机、微处理器等实现。In an embodiment of the invention, the control module can be implemented using a microcontroller, a microprocessor, or the like.
在一实施例中，采样模块包括AD转换模块，采样经过信号放大器的检测信号。In an embodiment, the sampling module includes an AD conversion module that samples the detection signal through the signal amplifier.
作为选择，为了防止误报，每次检测到酒精浓度超标，语音模块控制扬声器只播报三次。本发明为了进一步的降低误报，同时加入后台服务中心的人工交互判断服务功能。Alternatively, in order to prevent false positives, the voice module controls the speaker to only broadcast three times each time the alcohol concentration is exceeded. In order to further reduce false alarms, the present invention also joins the human interaction judgment service function of the background service center.
控制模块时刻接受来自定位模块传送的位置信息，但并不发送给后台服务中心，以节省流量。只有当控制模块判断酒精浓度超标时（作为触发条件），才会立即将位置信息和报警信息一起通过无线通信信道自动传给后台服务中心。The control module accepts location information transmitted from the positioning module at all times, but does not send it to the background service center to save traffic. Only when the control module judges that the alcohol concentration exceeds the standard (as a trigger condition), the position information and the alarm information are automatically transmitted to the background service center through the wireless communication channel.

The in-vehicle navigation device 100 is configured to send the alarm information and the satellite navigation and positioning information to the background service center through the wireless communication channel when the in-vehicle alcohol concentration detection result exceeds the standard, so as to provide the corresponding safe driving service by the background.
图5是根据本发明一实施例的具有酒精检测功能的车载导航设备的供电配置的示意图。如图5所示，在本发明一实施例，车载导航设备的供电配置如下：由汽车供电模块为抽气风扇、语音模块和扬声器供电；为了减少汽车供电模块电压扰动的影响，采用干电池为酒精传感器、信号放大器和单片机供电。检测电路用于检测汽车ACC/门状态，还可用于设置浓度阈值。FIG. 5 is a schematic diagram of a power supply configuration of an in-vehicle navigation device having an alcohol detecting function according to an embodiment of the present invention.

由于本发明是通过主动检测空气中酒精的含量，以此判断驾驶员是否饮酒。车内密闭空间较大，气体中的酒精分子含量完全靠驾驶员体液挥发所致。所以，车内密闭空间中的酒精浓度极低，致使检测难度大，虚警概率增大。本发明在传统的车载导航仪上集成酒精浓度检测模块和通信模块，将酒精浓度检测结果通过通信模块发送给后台服务中心，进而采取相应的服务措施。 Since the present invention determines the driver's drinking by actively detecting the amount of alcohol in the air. The confined space inside the car is large, and the molecular content of alcohol in the gas is completely caused by the volatilization of the driver's body fluid. Therefore, the concentration of alcohol in the confined space of the car is extremely low, which makes the detection difficult and the probability of false alarm increases. The invention integrates the alcohol concentration detecting module and the communication module on the traditional car navigation device, and sends the alcohol concentration detection result to the background service center through the communication module, and then takes corresponding service measures.
