Abstract
The utility mode relates to a power measurement and control instrument with a profibus- decentralized periphery (DP) communication interface. The power measurement and control instrument comprises a central processing unit (CPU), the CPU is connected with the profibus-dp communication interface, and the CPU is further connected with an analog/digital (A/D) module, a display module and a key module. The power measurement and control instrument with the profibus-DP communication interface has the advantages of being high in transmission rate.
Description
Technical field
The utility model relates to a kind of electric power observation and control instrument, especially relates to a kind of electric power observation and control instrument of the PROFIBUS-DP of having communication interface.
Background technology
At present, the electric power observation and control instrument all need be installed communication interface, to realize external communication, sends measuring and control data, accepts external command; And conventional electric power observation and control instrument adopts the Modbus interface, the highest 9.6M/S that only can reach of its transfer rate, and the impact of being connected up of its speed, and especially in the situation that some environments for use are abominable, communication efficiency is had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of transfer rate the high electric power observation and control instrument with the PROFIBUS-DP communication interface.
The purpose of this utility model is achieved in that a kind of electric power observation and control instrument with the PROFIBUS-DP communication interface, and described instrument includes CPU, is connected with the PROFIBUS-DP communication interface on the described CPU.
The electric power observation and control instrument of the utility model band PROFIBUS-DP communication interface also is connected with A/D module, display module and key-press module on the described CPU.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has been owing to having adopted the PROFIBUS-DP communication interface of PROFIBUS agreement to realize being connected with the communication in the external world, thereby has higher bandwidth and the speed of Geng Gao.
Description of drawings
Fig. 1 is the circuit block diagram of the electric power observation and control instrument of the utility model band PROFIBUS-DP communication interface.
Embodiment
Referring to Fig. 1, a kind of electric power observation and control instrument with the PROFIBUS-DP communication interface that the utility model relates to, described instrument includes CPU, is connected with A/D module, display module, key-press module and PROFIBUS-DP communication interface on the described CPU.
During use, the utility model is connected by communication by band PROFIBUS-DP communication interface and extraneous the realization, and band PROFIBUS-DP communication interface is operated under the PROFIBUS-DP, and transmission bandwidth is larger, and transfer rate can reach more than the 12M/S especially.
Claims (2)
