Multi-sensor complements the advantages of unmanned vehicles

Multi-sensor complements the advantages of unmanned vehicles

2016-12-16

Today, self-driving vehicles are no longer regarded as science fiction, but as revolutionary technological products that will be realized now! The main reason is that, with the advent of advanced driver assistance systems (ADAS) systems and the promotion and development of unmanned driving, cars need to know their surroundings well. The driver can perceive the environment around us, make judgments at the same time, and react quickly in different situations. However, no one is perfect, we will be tired, distracted, and make mistakes due to mistakes. In order to improve safety, automakers are designing ADAS solutions for passenger cars. Automobiles rely on a variety of sensors to sense the complex surrounding environment in different situations. Then, these data will be transmitted to high-precision processors such as TITDA2x, and finally used for automatic emergency braking (AEB), lane departure warning (LDW) and blind spot monitoring functions.     　　There are mainly the following types of sensors used to sense the surrounding environment in autonomous driving technology. 　　Passive sensors-mainly used to sense rays reflected or emitted from objects. 　　Visual image sensor-all imagers operate in the visible spectrum 　　Infrared image sensor-operating outside the visible spectrum. It can be near infrared or thermal infrared (far infrared). 　　Passive sensors are affected by the environment-at different times, weather, etc. For example, visual sensors are affected by the amount of visible light at different times of the day. 　　Active sensor-by emitting rays and measuring the response of the reflected signal. The advantage is that the measurement results can be obtained at any time, regardless of time or season. 　　Radar-by emitting radio waves, the distance, direction and speed of the object are determined based on the radio waves reflected from the object 　　Ultrasound-by emitting ultrasonic waves, the distance of the object is determined according to the ultrasonic waves reflected from the object 　　Lidar-Determine the distance of an object by scanning the laser light reflected from an object 　　Time of flight-use the camera to measure the time taken for the infrared beam to bounce from the object to the sensor to determine the distance of the object 　　Structured light-Project a known light pattern onto an object, for example by TI's Digital Light Processing (DLP) equipment. Subsequently, the camera will capture the deformed light map and analyze it to determine the distance of the object. 　　In order to provide enhanced accuracy, reliability, and durability in a variety of different situations, it is usually necessary to use at least one sensor to observe the same scene. All sensor technologies have their inherent limitations and advantages. Different sensor technologies can be combined to fuse data from different sensors in the same scene, thereby providing a more stable and durable solution, which compares view confusion through data fusion. A typical example is the combination of visible light sensor and radar.   　　Dismantling autonomous driving technology 　　Gill Pratt, head of Toyota Research Institute, listed several technologies related to unmanned vehicles. The first is the smartphone, and its related technologies, low-voltage computer processors, computer vision chips and photographic lenses have become "incredibly cheap and popular." 　　Moreover, cars have shifted from the power plant as the center to the computer as the center. For example, they are equipped with driving recorders, front and rear sensors, and other technologies to avoid hitting objects and warn driving. In addition, the map data system used to identify locations and guide directions, whether it is GPS positioning or Google Map, has become more and more accurate. 　　Deep learning has brought computer perception capabilities closer and closer to humans, allowing unmanned vehicles to recognize the difference between bicycles and pedestrians, signs and trees. Gill Pratt pointed out that the annual "ImageNet Image Recognition Contest" will test the accuracy of using deep learning algorithms to recognize pictures and images. A few years ago, the error rate was as high as 30%, but last year, the error rate has dropped to less than 5%.  　　These key sensing technologies and computing capabilities form the basis for the realization of unmanned vehicles, and most of them overlap with the technologies used in ADAS (Advanced Driver Assistance System).   　　How do self-driving cars see the world     　　Why do you need so many kinds of sensors? Complementary advantages and disadvantages     　　At present, most automakers are equipped with "autopilot" functions in mass-produced vehicles, including Tesla, Volvo, Mercedes-Benz, Audi, etc., in fact, they are equipped with ADAS. If NHTSA's level of autonomous driving is used, most of them are in the first place. Second to third level. However, Google, Ford and Baidu hope to ski

Aircraft manufacturing is inseparable from sensors, and the rare metal germanium is widely used

Aircraft manufacturing is inseparable from sensors, and the rare metal germanium is widely used

2016-10-25

In order to obtain information from the outside world, people must resort to sensory organs. But in many real activities, it is far from enough to rely on people's own sense organs. Therefore, sensors came into being and are widely used in various industries. Aircraft manufacturing is an area where sensors are widely used, and rare metal germanium, as an important raw material for sensors, plays an indispensable role in it.   Fiber optic sensors monitor aircraft flight data   As a new type of sensor, the optical fiber sensor is made in the "hair" thickness of the optical fiber to achieve the measurement of various physical parameters such as strain, temperature, pressure, acceleration, etc. It can withstand high voltage and resist electromagnetic interference. It can also be buried inside the structural body and is mostly used for online monitoring, such as bridges, dams, oil depots, railways, etc.   The use of optical fiber sensors can not only provide safety warnings for abnormal conditions through data, and achieve long-term health judgment and life prediction through data accumulation, but also provide data support for the deformation of the aircraft wing, making the flight safer and more intelligent.   Inclination sensor measures aircraft flight angle   The best advantage of the tilt sensor is that it can directly output tilt data such as angle, which can be used to display the pitch and roll attitude of the passenger plane.   When the passenger plane is flying normally, the tilt sensor can measure the current pitch angle and roll angle of the passenger plane in real time, and transmit the tilt angle signal to the display system, so that the captain or co-pilot can understand the current flight attitude of the passenger plane in real time , Which greatly improves the safety of passenger aircraft flight.   Pressure sensor to ensure accurate atmospheric data   Pressure sensors are mainly used in the measurement of acceleration, pressure and force. For example, the pressure type accelerometer is a commonly used accelerometer. It has the advantages of simple structure, small size, light weight, and long service life. It is used in aircraft vibration and shock measurement. The pressure sensor can also be used to measure the combustion pressure and vacuum degree of the aircraft engine.     Altitude sensor measures the aircraft's flight altitude   The altimeter is an important sensor in the aircraft, which plays a very important role in the safe flight and autonomous control of the aircraft. Take the helicopter as an example. The vertical control of the helicopter is realized by controlling the lift of the main rotor. The altitude information and vertical speed information of the vertical control come from the altitude sensor, which records the air pressure on the ground and compares it with the air pressure value of the helicopter during flight. The higher the flight, the lower the pressure, and the current altitude of the helicopter can be calculated by the difference between the two.   By changing the height, the vertical speed can be calculated. But once the altitude sensor fails, the vertical control system of the unmanned helicopter will have problems, leading to serious accidents.   In addition to the above-mentioned examples, the application of sensors on aircraft include: temperature sensors measure the temperature of aircraft engines, temperature and humidity sensors measure the temperature and humidity in the aircraft room, oil level sensors measure the fuel level of the mailbox in the aircraft, acceleration sensors and speed sensors measurement The acceleration and speed of the aircraft flying, the smoke sensor for smoke alarm, the ultrasonic sensor to monitor the position of the aircraft, and the inertial sensor and so on.   Semiconductor material sensors are one of the most common sensors, which are sensors made of various physical, chemical and biological properties of semiconductor materials. There are many types of semiconductor sensors, which utilize nearly a hundred physical effects and material characteristics, and have multiple sensory functions similar to those of human eyes, ears, nose, tongue, and skin. The rare metal germanium is an important semiconductor material, which is sparsely distributed and has no concentrated germanium ore. Global germanium resources are scarce. China is the world's second largest germanium resource country after the United States, which affects the global germanium supply.   In view of the importance and scarcity of germanium, the state began to plan its strategic purchase and storage in 2011. The Pan-Asian Nonferrous Metals Exchange, established in the same year, also took germanium as one of the listed products, and used the power of private capital to purchase and store, and form a benign complement to the state. Nowadays, another new type of internet finance platform under Pan Asia Group-Pan Rong.com will also list germani
