Description
The utility model belongs to the ammeter field, particularly a kind of ammeter that is used for the multi-user power-driven management.
Normally used ammeter mainly contains following several mode: 1. Every household has an ammeter for the most employing of traditional ammeter, and inaccurate, the easy stealing of metering is arranged, and is unfavorable for management; 2. the current-voltage transformer that uses in recent years though be difficult for stealing, because its linearity is bad, make its metering inaccurate, and volume is big, cost is high.
The purpose of this utility model provides a kind of multi-user's ammeter.Its linearity is good, and accurate measurement is simple in structure, use, combined and instant, and volume is little, and thief-proof electrically strong, is convenient to management.
For reaching above-mentioned purpose, of the present utility model being characterised in that is characterized in that the power supply that enters ammeter cabinet 8 is provided with user's electric energy acquisition card 1, power supply is connected with each user's power switch 11 through user's electric energy acquisition card 1, the pulse output end of user's electric energy acquisition card 1 is connected with the input end of hyperchannel gating module 9, the output terminal of hyperchannel gating module 9 is connected with the input end of single-chip microcomputer 2, and four output terminals of single-chip microcomputer 2 are connected with display module 3, IC module for reading and writing 5, data memory module 6 and teletransmission communication module 4 respectively.
Enter on the power supply of ammeter cabinet 8 several user's electric energy acquisition cards 1 can be set.
Hyperchannel gating module 9 is more than one.
User's electric energy acquisition card 1 preferably adopts electric energy metrical special IC capture card.
The utility model is owing to adopt the electric energy metrical special IC, and therefore simple in structure, cost is low; Adopt shunt, so volume is little, accurate measurement, adopts card plugging structure, can use easily and make up, and can be used for the ammeter of 1-24 family or more different user numbers.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a circuit structure diagram of the present utility model;
Fig. 2 is a chassis structure chart of the present utility model;
Fig. 3 is a panel structure chart of the present utility model.
Referring to 2 and Fig. 3.The cabinet 8 of this multi-user ammeter is connected with panel 12, and wherein capture card 1 is connected with pulse signal input adapter 7.Panel 12 is provided with: 1.. and teletransmission communication module 4 joints, carry out teletransmission with the data of user power utilization amount; 2. the interface of .IC module for reading and writing 5, the user can will write data storage module 6 after the surplus addition in the electric weight of its purchase and the data storage module 6; 3.. the display window 10 of display module makes the user read the electricity consumption situation of oneself at any time.
Referring to Fig. 1 and Fig. 2.The power supply that enters ammeter cabinet 8 is provided with user's electric energy acquisition card 1, and user's electric energy acquisition card 1 preferably adopts electric energy metrical special IC capture card.The plug-in card quantity of user's electric energy acquisition card 1 and number of users coupling.Power supply is connected with each user's power switch 11 behind user's electric energy acquisition card 1.The pulse output end of user's electric energy acquisition card 1 is connected with the input end of hyperchannel gating module 9, the output terminal of hyperchannel gating module 9 is connected with the input end of single-chip microcomputer 2, an output terminal of single-chip microcomputer 2 is connected with display module, three output terminals are connected with teletransmission communication module 4, IC module for reading and writing 5, data storage module 6 respectively in addition, and transmit in single-chip microcomputer 2 with the signal that the input end of each hyperchannel gating module 9 is connected to control each hyperchannel gating module 9 respectively single-chip microcomputer 2 selecting sides.When power supply behind user's electric energy acquisition card 1, capture card 1 is to user power supply, capture card 1 is converted to pulse signal according to user's power consumption in real time simultaneously.Pulse signal enters hyperchannel gating module 9, and hyperchannel gating module 9 can be imported the pulse signal of 1-8 or more users.Single-chip microcomputer 2 selects the pulse signal of a hyperchannel gating module 9 to carry out the processing of timesharing accumulative total successively one by one according to the program that is arranged on wherein successively.After conversion of signals after the processing is the numeral of power consumption, show through display module 3 respectively, make the user can understand the electricity consumption situation of oneself intuitively; Power consumption through 6 couples of users of data storage module is stored; Through teletransmission communication module 4 data of user power utilization amount are carried out teletransmission, can realize long-range charge.
Write data storage module 6 in the electric weight input data storage module 6 that single-chip microcomputer 2 will the user be bought by IC module for reading and writing 5 with after the remaining power consumption addition of user, successively decrease according to user's power consumption.
And so forth, multi-user's ammeter is constantly worked.
