Abstract
The invention belongs to the technical field of industrial control, and particularly relates to an intelligent sensor. The intelligent sensor comprises a DSP processor component and an ARM processor component connected with the DSP processor component. The intelligent sensor has the advantages that ordinary sensor analog signals in an industrial control system can be transformed to digital signals, the digital signals are sent to a field bus after related processing is conducted, and thus an ordinary sensor can also be applied to an industrial control network to build a field bus control system; moreover, the intelligent sensor is applicable to most ordinary sensors and has certain universality.

Background technology
With computer network, communication and the development of control technology, industrial control system is by original single, independent control
System development develops into field bus control system from Distributed Control System to complicated, integrated industrial control network.Fieldbus
The features such as control system is with its flexible control mode, information sharing, low cost, has been widely used in the control system of complexity
In system.Basic demand of the field bus control system to apparatus for network node is that will have to calculate and communication capacity, thus to control
The important node of network processed --- sensor proposes intelligent requirements, i.e., with computing function and communication function.At present, for
The Application in Sensing of controlling network has the disadvantage controller overload typically using controller and sensor as solution, and
Due to the reason that transducing signal process is not separated by, the fault-tolerance of this framework is not strong.Therefore, intelligence sensor can gather sensing
Digital signal, after data processing, is sent to fieldbus by the analogue signal of device, and sensor is changed into calculating and is led to
The network node of letter ability, improves the reliability of sensing function.
The content of the invention
It is an object of the present invention to provide a kind of intelligence sensor, make the sensor in industrial control system also can be in industry
It is applied in controlling network, to set up field bus control system, and intelligence sensor is applied to most of sensor,
With certain versatility.
What the above-mentioned technical problem of the present invention was mainly addressed by following technical proposals：
