Sensor in industrial automatic control, environment, transportation, medical, household appliances and other fields of typical applications

In recent years, due to the continuous development of sensor and perfect, has been widely used in national defense, military, aerospace, civil engineering, electric power, energy, robots, industrial automatic control, environmental protection, transportation, medical chemical industry, household appliances and remote sensing technology. Let's look at some typical applications. 1) Sensor application in aerospace field is shown in figure 2 spacecraft in addition to using the sensor for speed, acceleration and flight distance measurement, the direction of flight, flight, flight environment, the state of the vehicle itself and the internal equipment monitoring are also tested by sensors, and internal environment ( Such as humidity, temperature, air composition, etc. ) Through the sensor for testing. Figure 2 sensors in aerospace applications in addition, from the aircraft, satellites, spacecraft and ships to the vast area of measured object and its state over a long distance is remote sensing technology to carry out large-scale detection applications. In figure 3 for satellite through remote sensing technology of the United States air force base. Figure 3 sensors in the aerospace application example 2) Sensors in the application of robot in labor intensity big place or dangerous operations and some of the high speed, high precision work, has gradually use robots to replace human work. But to make the robots and the function of the people more close, this is for robot vision sensor and touch sensors installed, make robots of objects through visual recognition and detection, through the touch pressure sensation on bodies, force, sliding feeling and weight. As shown in figure 4 robot control is used in a wide variety of sensors. 3) Sensor in the application of industrial automatic control system is the first step of automatic detection and automatic control, if there is no sensor to the original information ( Signal or parameters) Accurate and reliable measurement, will not be able to realize from the signal extraction, transformation, processing to the production or control process automation. Visible, sensor in automatic control system is essential. As shown in figure 5 is sensor application instance in the building automatic control system. 4) Sensor application in environmental protection of global air pollution, water pollution and noise have been seriously destroy the ecological balance of the earth and the survival of our environment, to protect the environment, using the sensor made of various environmental monitoring instrument is playing a positive role. Such as biological sensors to monitor water quality, pollution monitoring and control system in the position of the test, to identify the components of wastewater, etc. , all use sensors to monitor. As shown in figure 6 for the application of sensor in flue gas measurement. Figure 6 sensor in the application of environmental protection. 5) Sensor in the medical application of sensor in medicine can be used for the surface of human body and the internal temperature, blood pressure, chamber pressure and flow of blood and breath, tumor, pulse and blood analysis and the diagnosis of heart sounds and heart brain waves are difficult. In the early diagnosis, early treatment, remote diagnosis and the development of artificial organs such as wide range. Figure 7 sensors for applications such as in medicine: fiber Bragg grating sensors can be minimal violation measure temperature, pressure, acoustic field of the human tissue of local information accurately. Fiber Bragg grating sensors can also be used to measure the efficiency of the heart, heart function monitoring. Biomedical sensor is indispensable in modern medical equipment one of the key parts. 6) Sensor in the application of transportation is also very widely used in transportation, the use of sensors in vehicle transportation axle number, wheelbase, speed monitoring, type classification, dynamic weighing, toll station platform balances, stop taking pictures, parking area monitoring, traffic information collection, Road monitoring) And the airport taxiway. In the vehicle has not only confined to the speed, distance and engine rotating speed monitoring, also used in security monitoring, such as automobile airbag systems, anti-theft devices, anti-slip control system, anti-lock brakes, and electronic speed control device, exhaust gas recycling device, electronic fuel injection equipment and vehicles, such as a 'black box' has been the actual application. 7) Sensor application in daily life are everywhere in our daily life, as shown in figure 8 USES the sensor of household appliances: refrigerators, the temperature sensor in rice cooker; The temperature and humidity sensor in air conditioning; The liquid level sensor in the washing machine; Gas burner in the leaking gas sensor; Water meter, electric meter, infrared remote control of TV and DVD player; The light sensor in the camera; Car fuel meter and speed meter and so on.
