Intelligent pressure sensor characteristics and composition

What is intelligent pressure sensor, the sensing application history, the introduction of intelligence is a revolutionary subversion of the traditional sensing technology, intelligent pressure sensor of intelligent, of course, refers to the multiple functions of the same or different sensitive devices on the same chip constitute a sensor array, there are three main aspects: the meaning of a sensitive unit, is exactly the same multiple function integrated manufacturing, on the same chip which is used to measure by measuring the spatial distribution of information, such as pressure sensor array or known as CCD device. Two, is the same for multiple structure, the equivalent of sensitive element for integration, such as integrated together to form different gas sensitive sensor yuan 'electronic nose', use a variety of sensitive element to the cross of different gas sensitive effect, use the advanced data processing such as neural network pattern recognition technology, various components of the mixed gas monitoring at the same time, get the composition of mixed gas information, at the same time to improve the measurement precision of the gas sensors, This layer of meaning on the integration of a kind of circumstance is to integrate the different range of sensing yuan together, can according to the size of the stay measurement in each sensor switch between yuan and in ensuring measurement accuracy at the same time, expand the sensor measurement range. Of course, more simple point of intelligent pressure sensor is mainly composed of sensor, microprocessor and related circuit. Pressure sensor can not only of sensor measurement data computing, storage, data processing, can also be adjusted through the feedback loop of sensor. The computer give full play to the functions of various software, can complete the hardware is difficult to complete tasks, thus greatly reduce the difficulty of the sensor manufacturing, improve the performance of the sensor to reduce costs. Sensors measured quantities will be converted into corresponding electrical signals, to the signal conditioning circuit, filtering, amplification, die - Number converted to micro computer. If divided from the structure, smart sensors can be divided into integrated type, hybrid and module type. Integrated intelligent sensor is sensitive to one or more devices and microprocessors, signal processing circuits are integrated on the same silicon chip, integrated high integration, small volume, but the current technical level is difficult to achieve; Do sensors, and microprocessor, the signal processing circuit is on different chip, is a hybrid intelligent sensor, at present this kind of structure is more; Primary intelligent sensor can also be composed of many independent modules, such as micro computer, signal conditioning circuit module, data circuit module, a display circuit module and sensor assembly in the same shell structure of intelligent sensor module type conceal. 智能压力传感器是什么? 传感器上的应用和发展,智能的引入是一种革命性的颠覆传统的传感技术。 当然,智能压力传感器是指多个相同或不同功能的传感器在同一芯片组成传感器阵列。 义:一是制造多个传感单元具有相同的功能在一个芯片上测量测量的空间分布信息,如压力传感器阵列或CCD的设备我们都很熟悉。 其次,它集成了许多敏感单位具有相同的结构和类似的功能,例如,它集成了不同的气体传感元素形成一个“ 电子鼻子” 。 通过使用跨 灵敏度的影响不同气体敏感元素,采用先进的数据处理技术如神经网络模式识别,可用于各种团体的混合气体。 同时,混合气体的成分信息,和气体传感器的测量精度提高。 测量范围。 当然,简单的智能压力传感器主要由传感器、微处理器和相关电路。 压力传感器不仅可以计算,存储和处理传感器的测量数据,但也通过反馈回路调整传感器。 因为电脑给充分发挥各种软件的功能,它可以完成硬件难以完成的任务,从而大大减少传感器制造的难度,提高传感器的性能,降低成本。 传感器将测量的物理量转换成相应的电信号,它被发送到滤波的信号调节电路,放大,模拟 微机数字转换,然后。 如果结构划分,智能传感器可分为综合、混合和模块化。 集成智能传感器和微处理器是一个或多个敏感设备,信号处理电路集成在同一硅片上,高集成,体积小,但目前的技术水平是难以实现的; 传感器和微处理器、信号处理电路在不同的芯片,构成混合智能传感器。 目前,有很多这样的结构; 主要的智能传感器也可以由许多独立的模块,如微机、信号调节电路模块,数据电路模块、显示电路模块和传感器组装在同一壳体结构形成一个模块化的智能传感器。
