Description

Electric energy automatic charging device

Technical field

The utility model belongs to the electronics message accounting, is adapted at the use of paying the fees of generating plant, electric substation, large electricity consumer's automatic gauge.

Background technology

At present, some other enterprises such as large electricity consumer, generating plant, electric substation, the electricity consumption metering all is to adopt separate type single household list table to calculate, each user carries out cumulative calculation at the individual event record sheet of oneself, and this metering method is relatively backward, and Fei Gong is time-consuming can not to manage concentratedly, so that mismanagement causes a large amount of wastes, because large electricity consumer's the continuous increase and the increase of power consumption are brought very big difficulty for the management of power consumption, even cause massive losses economically.

Summary of the invention

For solving the deficiency of above message accounting, the purpose of this utility model provides a kind of electrical energy automatic measure message accounting, utilize computing machine and end sensor and communication interface, can carry out the measuring control of science effectively to power plant, transformer station and large electricity consumer, to adapt to the needs of electricity market.

The structural design of the utility model is achieved in that this message accounting is shown by 16 road intelligent data capture cards, Display And Keyboard control card, technical grade 486 motherboards, high capacity electric board, touch keyboard, LED and LCD and external communication interface is formed (as shown in Figure 1).

Its connection is that 16 circuit-switched data capture cards are to be core with 8031 unit machines, and counting shows and carries out communication link by isa bus and 486 host CPUs; Keyboard connects the touch keyboard of front panel with display control card, being connected with led state display and LCD information simultaneously shows, keyboard and display control card are joined by isa bus interface and 486 plates, be connected with the solid-state electronic dish that uses the isa bus compatibility with motherboard 486 machines, preserve user program, system program and all kinds of energy value data, but data long preservation under no external power situation and not losing, 16 road intelligent data capture cards wherein in detail by shown in Figure 2,16 road input signals link by isolation and anti-jamming circuit and reception buffer, reception buffer connects with 8031 single-chip microcomputers by data bus, 8031 single-chip microcomputers connect with reception buffer by acquisition control circuit again, reception buffer all connects with the isa bus interface by bus with 8031 single-chip microcomputers, bus directly connects with fixed storage and random memory again, and last isa bus interface connects with motherboard 486CPU; Wherein display interface (as shown in Figure 3) is to join by lcd controller and isa bus interface, status displays LED shows and operation keyboard all joins by keyboard and display controller and isa bus interface, last bus interface and motherboard 486CPU link, each circuit-switched data of inserting and inquire about of demonstration and keyboard portion parameter provides a kind of user interface fast, and keyboard connects with 486 host CPU interfaces with interrupt mode.

The advantage of the utility model: circuit structure is simple, connects with intelligent acquisition card and computing machine, and collection capacity is big, calculate soon, accurately errorless, by the practicable far distance controlled metering of communication interface, have very big economic benefit, bring very big benefit for the scientific management of electric energy.
