Abstract
The utility model relates to an IC (integrated circuit) card intelligent kilowatt-hour meter, which comprises a basic meter and a controller, the controller comprises a sampling module, a display module, an IC card read-write module, a regulated power supply and a solid-state relay which are connected with a CPU (central processing unit), the on-off of the solid-state relay is controlled by the CPU, the display module is distributed on the front of the basic meter, the controller is arranged under the display module, the sampling module is arranged under the controller, the IC card read-write module is connected with an antenna, and the antenna is circularly distributed around the display module. The IC card intelligent kilowatt-hour meter has the advantages of high anti-interference capability, small spatial structure, high data processing speed, simple structure, low cost, simplicity in operation, convenience in maintenance, low power consumption and small radiant quantity, and can give the alarm.
Description
Technical field
The utility model belongs to ammeter field, especially a kind of IC-card intelligent electric meter.
Background technology
Pre-payment is as a kind of consumption pattern, be present in every field, the appearance of IC-card intelligent electric meter, to administration departments, provide efficiently service easily, what application was many at present is Contact Type Ic Card plug, time has been grown Contact Type Ic Card chip and has easily damaged, IC-card deck is easily loosening, be exposed to for a long time in air, dust is easily accumulated, easy-clear not, affect serviceable life, non-contact IC is mainly used in public transport field at present, and non-contact IC card can be made various shapes, all size, be easy to carry, closely induction can complete pre-payment read-write process, if non-contact IC card is applied in ammeter, still also there is the problem of easily disturbing, data processing speed is slow, and what the break-make of electric power system adopted is relay switch, and there is larger electric arc the moment of break-make, thereby produces a certain amount of radiation.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and provides that a kind of non-contact IC structure, processing speed are fast, easy to maintenance, the IC-card intelligent electric meter of low-power consumption.
The utility model solves the technical scheme that its technical matters adopts, a kind of IC-card intelligent electric meter, comprise base table, controller, controller comprises sampling module, display module, IC-card module for reading and writing and stabilized voltage supply, the solid-state relay being connected with CPU, and CPU controls solid-state relay break-make, and display module is distributed in the front of base table, display module below is provided with controller, controller below is provided with sampling module, and IC-card module for reading and writing connects antenna, and antenna annular is distributed in around display module.
Further, described CPU is that MSP430F413 series monolithic carries flash.
Further, described IC-card module for reading and writing 5 is RF Signal modules.
Principle of work: whole IC-card intelligent electric meter is powered by stabilized voltage supply, CPU obtains electric current by sampling module and measures, and by reading IC-card module for reading and writing, obtains prepayment information, according to prepayment information, control solid-state relay break-make, under normal service condition, solid-state relay is closed, when prepaid data is when approaching a certain fixed value, display module flicker, with reminding user, pay the fees, when prepaid data is to 0 time, solid-state relay disconnects stops power supply; User is swiped the card and is paid the fees by IC-card module for reading and writing.
Compared with prior art, the utility model antijamming capability is strong, and space structure is little, and data processing speed is fast, and simple in structure, low-cost, simple to operate, easy to maintenance, low-power consumption, radiant quantity be little, IC-card intelligent electric meter that can alarm.
