Intelligent and multi-functional will become an important direction for sensor development
Today, with the highly developed information technology, the intelligence and multi-function of sensors will become an important direction for sensor development. Compared with traditional sensors, intelligent sensors have the following characteristics:
(1) It has logical judgment and statistical processing functions.
The detection data can be analyzed, statistically and corrected, and error compensation such as linearity, nonlinearity, temperature, noise, response time, cross sensing and slow drift can be performed, which improves the measurement accuracy.
(2) With self-diagnosis and self-calibration
The power-on self-test can be performed when the power is turned on, the operation self-test can be performed during the work, and the test can be self-diagnosed in real time to determine which component is faulty, and the work reliability is improved.
(3) With adaptive, self-adjusting function
The detection range and measurement method can be automatically selected according to the numerical value and the change of the physical quantity to be measured, and the applicability of the detection is improved.
(4) has a configuration function
Multi-sensor, multi-parameter composite measurement can be realized, which expands the range of detection and use.
(5) With memory and storage functions
It can access the test data at any time, speeding up the processing of information.
(6) With data communication function
The intelligent sensor has a data communication interface, which can directly connect with the computer and exchange information with each other, thereby improving the quality of information processing. Computer software plays a pivotal role in smart sensors. Thanks to the addition of “computerâ€, the smart sensor can manage and adjust the information detection process through various softwares to make it work in an optimal state, thereby enhancing the function of the sensor and improving the performance of the sensor. In addition, the use of computer software can achieve functions that are difficult to implement in hardware, because replacing some hardware with software can reduce the difficulty of manufacturing the sensor.
