From the 1st of the month, China began to implement the new regulations on heavy drunk driving: no matter whether it causes the consequences of a traffic accident, as long as there is a drunk driving act that is a crime, it will be punished by criminal detention for less than 6 months. A major accident in a drunk driving will be banned for life, and drunk driving on the road will be held criminally liable. The standard of drunk driving: alcohol content in blood ≥80mg/100ml; standard of driving after drinking: blood alcohol content ≥20mg/100ml, <80mg/100ml. The reason why there are such large-scale penalties is closely related to the wave of anti-drunk driving around the world, and in the auto industry itself, it has not stopped taking the initiative to self-discipline, that is, actively monitoring driving through the vehicle electronic system. Whether there is drunk driving behavior. This issue of Netease Automotive "Technology Lecture Hall" came to talk about this high-tech equipment. This article refers to the address: http:// First of all, it is certain that this is not fundamentally different from the detection technology commonly used by traffic police in countries around the world, and even its portability and accuracy are slightly lower. However, unlike the consequences of being trafficked by the traffic police, the drunk driving detection system detected the drunk driving, and the most severe punishment was not too much to start the vehicle. Secondly, the car drunk driving monitoring system is not a particularly high-tech technology. As early as 2007, Volvo proposed such a concept and introduced a technology called “Alcoguardâ€, although the technology is more The reasons for this have not been universalized, but it has created a technological precedent and laid a foundation for later technological development. Alcoguard Drinking and Driving Locking Device This is a fully integrated "Alcolock" in the car that utilizes advanced fuel cell technology, which is derived from the alcohol detection technology used by traffic police. The system consists of three parts, the wireless handheld device, which is responsible for measuring the alcohol concentration; the charging base is installed behind the floating center console; the dashboard has a corresponding information display function to inform the driver whether he has passed the alcohol test. It is about the same size and weight as a remote control, and the data can be stored for 30 minutes. Before the driver starts the car, he needs to blow the handheld device for 5 seconds. The LED light will display the test result, and the wireless signal will transmit the result to the vehicle equipment. If the alcohol content in the blood is 0 ~ 10mg / 100mL, the device will light green, then the engine can be started. If it is 10 to 20 mg/100 mL, although the engine can be started, a yellow light will be emitted to give the driver a driving warning. When it reaches 20mg/100mL or more, the engine will not start. There are several important reasons why Volvo's Alcoguard technology can't be popularized. First, the cost is high. The core component fuel cell has no breakthrough even in 2011, and the price increase caused by the inability of civilian vehicles to digest; The monitoring process is cumbersome, independent handheld devices, need to actively blow, long waiting time, etc., which greatly affect the user experience, so this device as an optional component will hardly be purchased. Even if Alcoguard exposes many problems, the automotive industry is always accompanied by the potential demand for such systems, so a user-friendly, non-contact test, fast test, and highly integrated vehicle-mounted drunk driving monitoring system Has become a major direction of major manufacturers. A research and development organization plan involving more than ten internationally renowned manufacturers including GM, Volkswagen, Ford, Mazda, Toyota, Nissan, Honda, BMW, Mercedes-Benz, Porsche, Chrysler, Jaguar, Land Rover and Mitsubishi has emerged. ——DADSS (Driver Alcohol Detecton System for Safety) driver alcohol monitoring safety system organization. This young organization has been in existence for two years and has proposed and prototyped many advanced test equipment prototype technologies, and has won worldwide recognition at numerous industry technical seminars. The technology is currently moving in two directions, single-touch and non-contact breath detection. The so-called single-finger contact method is very simple. Similar to the fingerprint collector, it collects enough data by the moment the finger presses the detection instrument to analyze the alcohol concentration in the blood. And the finger can be directly in contact with the instrument, and the results of the test data are also relatively accurate. However, how can it not be ingenious to guide the driver's hand to the detection instrument without affecting the original vehicle center console layout? The technician has found the easiest way to start the detection instrument and the engine. The switches are fused together to achieve a synchronous detection operation when the driver presses the start button, which not only utilizes the driver's active behavior, but also does not affect the user experience, and also allows the device to disappear into the invisible space and save space. The fly in the ointment is that this technology can make the driver unable to start the car when he is drunk, but it can't be monitored continuously after starting, so if the vehicle is started with the fingers of the non-drinker, it is still the same as the ordinary vehicle, and can't be anytime, anywhere. Continuous monitoring of the true state of the driver. Closer to the natural state, and the higher degree of integration with the whole vehicle is the non-contact breath detection type. The non-contact test method eliminates the impact on the user experience. Through multiple detectors arranged in the surrounding areas of the driver's seat such as the steering wheel, the instrument panel, the headrest, etc., the driver collects breath samples that are continuously exhaled by the driver to determine the driver. Is there a drunk driving behavior? One advantage of such a layout system is that all test equipment can acquire data in the natural state of the driver, and can collect data in real time and take effect in real time. Therefore, it is necessary to avoid the weakness of the previous test means, the inability to continue testing, and the loss of effectiveness once the vehicle is started. This form of testing is recognized as the most promising technology for the next generation of models. Maybe one day you drive a new car you just bought. After drinking and sitting in the car, you can't start the car. Don't think that the car is broken. In fact, it is silently protecting your safety.
7.1 Home Theater Speaker is the common name for an eight-channel surround Audio System commonly used in home theatre configurations. It adds two additional speakers to the more conventional 5.1 audio configuration. As with 5.1 surround sound, 7.1 Home Theater Speaker System uses the standard front, center, and Subwoofer Speaker configuration. However, whereas a 5.1 Speaker combines both surround and rear channel effects into two channels (commonly configured in home theatre set-ups as two rear surround speakers), a 7.1 Speaker splits the surround and rear channel information into four distinct channels, in which sound effects are directed to left and right surround channels, plus two rear surround channels.In a 7.1 Home Theater Speaker set-up, the surround speakers are placed to the side of the listener's position and the rear speakers are placed behind the listener. In addition, with the advent of Dolby Pro Logic IIz and DTS Neo:X, 7.1 Speaker can also refer to 7.1 surround sound configurations with the addition of two front height channels positioned above the front channels or two front wide channels positioned between the front and surround channels.
