In daily life, most people control smart home devices through mobile phone operation and voice assistants, but with the development of science and technology, more and more work is replaced by intelligence, and the emergence of smart sensors is more convenient for people to enjoy smart life. What are the advantages of smart sensors compared to mobile phone operation and voice assistants?
First, high accuracy: intelligent sensors can remove zero errors by automatically correcting zeros, compare with the standard reference reference in real time to automatically calibrate the overall system, automatically correct the system errors such as nonlinearity of the overall system, and eliminate accidental errors by processing a large amount of data collected to ensure that the intelligent sensor has high accuracy.
Second, high reliability and strong stability: intelligent sensors can automatically compensate for the drift of system characteristics caused by changes in working conditions and environmental parameters, such as the drift of zero point and sensitivity caused by temperature changes; automatically change the range after the measured parameters change; can automatically conduct self-test of the system in real time, analyze and judge the rationality of data, and give emergency treatment schemes for abnormal situations.
Third, high signal-to-noise ratio and high resolution: intelligent sensors have the function of data storage, memory and information processing, digital filtering, data analysis, etc. can be carried out through software, so noise in the data can be removed and effective signals can be extracted; the impact of cross-sensitivity in multi-parameter states can also be eliminated through data fusion and neural network technology, so as to ensure that the measurement of specific parameters has a high resolution ability.
Fourth, strong adaptive ability: intelligent sensors can decide the power supply of each part according to the working conditions of the system, optimize the data transmission rate of the host computer, and ensure that the system works in the optimal low-power state.
Fifth, cost-effective: intelligent sensors do not pursue the perfection of the sensor itself like traditional sensors, but carefully design and debug all aspects of the sensor, but combine microprocessors and microcomputers, using low-cost integrated circuit processes and MEMS processes, plus powerful software to achieve the corresponding functions, so compared to traditional sensors, intelligent sensors have a high performance-price ratio.
Miniaturization: With the rapid promotion of microelectronics technology, smart sensors are developing in the direction of small and light to meet the needs of aviation, aerospace, national defense, miniaturization industry and civil equipment.
Seven, low power consumption: smart sensors generally use large-scale or ultra-large-scale CMOS circuits, so that the power consumption of the sensor is greatly reduced, some can be powered by stacked batteries or even coin cell batteries, and the design of standby mode is to make the power consumption of smart sensors lower.
The above pictures are all various intelligent sensors developed by Zhiting, and I hope to give you some reference opinions.
