Sensor research on intelligent sensor has become an international hot spot

In people's mind, sensors are widely used in automotive, industrial automation, aerospace, military engineering, environment detection, and other fields, few involved in electric field.

Now, not only in the field of smart grid has been found to the sensor, and the smart grid is expected to become the sensor using one of the biggest users. Establish a smart grid needed most of the cost required in terminal power distribution system and intelligent network terminal information system in electric power facilities, network security software and hardware construction, a large part of the investment on the sensor network, directly drive the sensor market. At the same time, in order to adapt to the construction of smart grid, demand, sensors are also in the direction of intelligent, systematic, networking, digital development.

Intelligent sensor is a sensor which has the function of information process, a microprocessor, has the ability of information acquisition, processing, exchange, is the product of sensors integrated with microprocessor. Smart grid, with a number of intelligent system, not separate individuals, but together with the equipment and technology products. In the monitoring of the first line of sensor devices are small, but absolutely vital. In the smart grid development, using the traditional sensor has not for some power quality and fault location quickly direct measurement and online monitoring. And the use of smart sensors can be directly measured, index, and failure to measure the quality of product (such as temperature, pressure, flow). For example, in order to meet the demand of the smart grid development, our country launched a optical fiber current sensor system, realized the pipeline current sensing system of full digital closed loop control, has good stability and linearity and high sensitivity, met the requirement range in a wide range of high precision measurement. Current, sensors on the smart sensor has become an international research hotspot and frontier. That should be taken to develop the intelligent sensor research, leap-forward development train of thought, is the key to the occupation of the future information technology commanding heights.

In the future, digital, information-based, Internet of things technology integration, will drive the sensor to the intelligent direction. As the sensor manufacturing cost is reduced, the market demand for sensor function also more and more comprehensive and specialized, intelligent sensor will also be popularization and application.
