Described ammeter thick film circuit is to calculate real-time user power utilization amount;
When described intelligent alarm is less than predetermined value in the user power utilization amount, functions of electricity purchasing cue is sent in the instruction that receives the output of ammeter thick film circuit;
Described smart card control device is connected with data-carrier store by data circuit, connects the IC-card that the user inserts, and reads the data on IC-card;
Described relay switch continues decline predetermined value power purchase not yet at electric weight after intelligent alarm sends functions of electricity purchasing cue, sends instruction and closes the ammeter switch, stops the electric power supply to the user, and ammeter also advances to cut out waiting status.
Further technical scheme is, described relay switch is the timing relay switch.
Further technical scheme is, described smart card control device comprises IC-card controller, PIC single-chip microcomputer and IC-card card reader.
Further technical scheme is, described PIC microcontroller is connected with power circuit, and power circuit is provided with the UPS uninterrupted power source.
Further technical scheme is, described liquid crystal display is section type liquid crystal display.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is integrated in the watchcase of an integral body by the movement by traditional ammeter and high-caliber telemetry circuit, both kept measuring accuracy, the automatic management function that has possessed again table metering running status, can effectively stop the malfunctioning behavior of control that artificial destruction system and private opening IC-card control system cause, the security that has improved electric meter system simultaneously.
2, the present invention selects the control module of PIC Series of MCU as electric meter system by employing, there is high sensitivity, low-work voltage, low-power consumption, adopt serial communication mode to be connected, to communicate by letter with peripheral components such as IC-cards simultaneously, simplified circuit structure, thereby reduced costs.
3, the present invention, by the section type liquid crystal display of selecting, can be used for according to different button operations, shows respectively time, the amount of money that prestores, flow, temperature, pressure and error message etc. that current system time, user set.Thereby the human-computer interaction interface of setting up good, improved practicality and the simplification of system operation.

The connection diagram that Fig. 1 is an embodiment of a kind of cassette intelligent electric meter of the present invention.
The connection diagram that Fig. 2 is a preferred embodiment of a kind of cassette intelligent electric meter of the present invention.
The connection diagram that Fig. 3 is another preferred embodiment of a kind of cassette intelligent electric meter of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows an embodiment of a kind of cassette intelligent electric meter of the present invention: a kind of cassette intelligent electric meter, comprise the PIC microcontroller, and the data-carrier store be connected with the PIC microcontroller respectively, ammeter thick film circuit, smart card control device, relay switch, liquid crystal display and intelligent alarm;
User's electric quantity data that described PIC microcontroller will be stored in data-carrier store takes out and shows by liquid crystal display, then processes and judged whether that metrical pulse arrives by logical operation, if there is metrical pulse to start counting and computing function;
Described ammeter thick film circuit is to calculate real-time user power utilization amount;
When described intelligent alarm is less than predetermined value in the user power utilization amount, functions of electricity purchasing cue is sent in the instruction that receives the output of ammeter thick film circuit;
