Abstract
The utility model provides a direct-current ammeter board card module which comprises a power source, a CPU (central processing unit) main card and multiple direct-current ammeter board cards. Communication among the direct-current ammeter board cards is realized by using isolated IIC buses, the direct-current ammeter board cards are responsible for data collection of electric energy parameters, and the CPU main card is responsible for processing and storing data collected by the direct-current ammeter board cards. Electrically absolute isolation among the board cards and the main card can be realized, and the module can be configured with power sources with different direct-current ammeter board cards, so that application in multi-voltage input scenes can be realized.
Description
Technical field
The utility model relates to the ammeter board card module, especially relevant DC meter board card module with independent current source.
Background technology
Along with the development of intelligent grid, the application of direct current supply, DC meter is just receiving increasing concern as wherein indispensable measuring apparatus.Current national with the new forms of energy construction as development strategy, the carrying out that the construction of intelligent grid is just like a raging fire, the occasion of dc measurement will be more and more extensive, the needs of dc measurement will be more and more urgent.The needs of building in order to satisfy acquiring electric energy information and intelligent grid, and the technical requirement of standard DC meter, the application of DC meter integrated circuit board is also more and more extensive.The DC meter integrated circuit board can effectively detect and information for DC current.Yet, how effectively to carry out carrying out reasonable arrangement between a plurality of DC meter cards, the work that makes its efficiently and accurately is the current problem that will solve.
The utility model content
The utility model relate between a kind of each integrated circuit board and and main card between can accomplish the DC meter board card module of the absolute isolation on electric.
For reaching above-mentioned utility model purpose, the utility model provides a kind of straight DC meter board card module, it is characterized in that: comprise power supply, CPU main card and a plurality of DC meter integrated circuit board, use the iic bus of isolation to communicate between described DC meter integrated circuit board, described DC meter integrated circuit board is responsible for the data acquisition of electrical energy parameter, and described CPU main card is responsible for the data of described DC meter integrated circuit board collection are processed and stored.
As further improvement of the utility model, on described every DC meter integrated circuit board independently power module is set all.
As further improvement of the utility model, in the power circuit of described every DC meter integrated circuit board overvoltage crowbar is set.
As further improvement of the utility model, reverse input protection circuit is set in the power circuit of described every DC meter integrated circuit board.
As further improvement of the utility model, it is characterized in that described CPU main card can be finished the data of 8 described DC meter integrated circuit boards and process.
Compared with prior art, between each integrated circuit board of DC meter board card module provided by the utility model and and main card between can accomplish absolute isolation on electric.The power supply of configurable different DC meter integrated circuit boards is realized application scenario under the multivoltage input scene simultaneously.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
