The purpose of this utility model is achieved through the following technical solutions: a kind of six charactrons are display type IC-card intelligent electric meter initiatively, mainly comprises power management module, metering module, control and execution module, MCU, charactron display module and IC-card module for reading and writing; Wherein, described power management module continues suitable and stable power supply for metering module, control and execution module, MCU, charactron display module and IC-card module for reading and writing provide; Described control and execution module, charactron display module and IC-card module for reading and writing all communicate with the MCU circuit and carry out two-way communication.Increased the red film of form optical filtering on the form of described charactron display module; and described charactron display module adopts the large form charactron that can demonstrate at most six figure places, all connect between the corresponding charactron of its each figure place and MCU and accesses triode and the protective resistance of a same size.Described IC-card module for reading and writing adopts the high secret IC-card of triple protection, its with earth terminal between connect the access protectiveness capacitor, the high secret IC-card of described triple protection is the IC-card that carries San Ji Rong silk, wherein, described San Ji Rong silk manufacturing state, installment state and three kinds of duties of use state of corresponding ammeter respectively of carrying, when making state, the fusing of IC-card Yi Ji Rong silk but second and third Ji Rong silk do not fuse when ammeter; When ammeter during in installment state, first and second Ji Rong silk fusing of IC-card, but San Ji Rong silk does not fuse; When using state, whole San Ji Rong silks of IC-card all fuse when ammeter.
Compared with prior art, a kind of six charactrons of the utility model initiatively charactron display module of display type IC-card intelligent electric meter have adopted six large form charactrons to show energy data, increased the figure place that can show information data, user and administrative authority can be identified and reading out data easily, stop misreading of data; The IC-card module for reading and writing of ammeter has adopted the high secret IC-card of triple protection, has improved security, confidentiality, the reliability of IC-card intelligent electric meter, Reliable guarantee all is provided for user's fund security and gerentocratic information management.
Description of drawings
Fig. 1 is the initiatively systematic schematic diagrams of display type IC-card intelligent electric meter of a kind of six charactrons of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, a kind of six charactrons are display type IC-card intelligent electric meter initiatively, mainly comprises power management module, metering module, control and execution module, MCU, charactron display module and IC-card module for reading and writing.Wherein, described power management module can be metering module, control and execution module, MCU(Micro Control Unit, micro-control unit), charactron display module and IC-card module for reading and writing provide and continue suitable and stable power supply; Described charactron display module adopts six large form charactrons that can show at most six figure places; Described IC-card module for reading and writing adopts the high secret IC-card of triple protection.Described control and execution module, charactron display module and IC-card module for reading and writing all communicate with the MCU circuit and carry out two-way communication.
Utilize charactron clear and reliablely and stablely show the energy data of six figure places in order to adapt to; correspondingly increased the window dimension of the charactron display module of ammeter; and increase the form red film that filters on form; equal triode and protective resistance that specification is identical of series connection access also between the corresponding charactron of each figure place in described charactron display module and MCU shows the stable, reliable of data to guarantee ammeter.Six charactrons of described charactron display module can show six figure places at most, wherein, and five integers of accumulative total power consumption, a decimal; Dump energy shows without decimal place.In order to save the resource of MCU, during described charactron display module normal operation, shown digital section is controlled by MCU with the position and is completed.Therefore, the data message of having realized the ammeter metering can once show on ammeter to be completed, be very easy to user and administrative authority and read and utilize data, stop misreading of data, also strengthened the display effect of ammeter data information and practicality, the aesthetics of ammeter simultaneously.
