Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model.
Embodiment
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of individual event local charge control intelligent electric energy meter, comprise the MCU micro control unit 1 for controlling whole electric energy meter processing data information, the computing unit 2 be connected with whole electric energy metrical unit, for storing the storage unit 3 of data, for showing the display unit 4 of the relevant information such as power information and expense and providing the power supply unit 9 of working power for each assembly of whole electric energy meter, described computing unit 2, storage unit 3, communication unit 7, display unit 4 is all connected with MCU micro control unit 1, the working routine of gauge assembly is stored in MCU micro control unit 1.Electric energy meter also comprises expense control unit 5, clock unit 6, communication unit 7, safety control module 8, and described expense control unit 5, clock unit 6, communication unit 7, safety control module 8 are connected with MCU micro control unit 1.Described expense control unit 5 has cost early-warning function, arrearage trip avoidance function to realize cost data by CPU communication card mutual.Cost early-warning function is be provided with a voice announcer in expense control unit 5, in MCU micro control unit 1, store one section of program, and set when electricity charge remaining sum is lower than the value set, the alarm that MCU micro control unit 1 controls in expense control unit 5 carries out low expense prompting to user; This alarm can adopt the reminding user of sound, light or other modes.Arrearage trip avoidance function is that relay is connected with MCU micro control unit 1 and is undertaken controlling its break-make by MCU micro control unit 1, stores one-stage control program simultaneously, set the minimum overdraw amount of money in MCU micro control unit 1 by installing a relay in expense control unit 5.When remaining sum is less than or equal to the warning amount of money of setting, electric energy meter can with sound, light or other mode reminding users; Overdraw amount of money real time record, when the amount of money of overdrawing is lower than the overdraw thresholding amount of money set, electric energy meter sends power-off signal, and control overhead switch interrupts is powered; After electric energy meter receives effective continuous information of paying tariff, the first deduction overdraw amount of money, when remaining sum is greater than setting value (being defaulted as zero), can makes electric energy meter be in permission "on" position by local or local mode, be powered by artificial local recovery.The clock unit 6 used adopts the hardware clock circuit with temperature compensation function, has calendar, timing, leap year auto-conversion function.
