<p>MICRO-COMPUTER INTELLIGENT SENSOR ELECTRIC METER MAKES VOLTAGE AND CURRENT ON POWER LINE PASS THROUGH DISTRIBUTION VOLTAGE/DISTRIBUTION CURRENT CIRCUIT AND THEN TO ANALOG/DIGITAL CONVERTER SO AS TO CONVERT INTO DIGITAL SIGNALS FOR THE CENTRAL PROCESSING UNIT (CPU) TO OPERATE AND CALCULATE. THE OPERATED AND CALCULATED INFORMATIONS INCLUDE ALTERNATING VOLTAGE, ALTERNATING CURRENT, POWER FACTOR, ACTIVE POWER, AND THE READING OF CONSUMED POWER. THE INFORMATIONS CAN BE DISPLAYED IN LIQUID CRYSTAL DISPLAY. AND, ANY ONE OF THESE INFORMATIONS CAN BE SELECTED OUT BY A KEYBOARD. THE SAID DEVICE CAN FURTHER RECEIVE OUTSIDE SIGNALS TRANSMITTED THROUGH RADIO WAVE AND CAN IDENTIFY WHETHER CODES OF THE SIGNALS ARE THE SAME AS ITS OWN OR NOT. IF THE CODES ARE THE SAME, THEY WILL BE MANAGED TOGETHER WITH SAID INFORMATIONS AND THEN BE SENT BACK THROUGH RADIO WAVE TO THE OUTSIDER WHO TRANSMITTED THE SIGNALS. BY THIS WAY, THE MANAGEMENT DEFECTS COMPANY CAN BE OVERCOMED. THE DEFECTS ARE AS FOLLOW: THE CONVENTIONAL ELECTRIC METER OF MECHANIC TYPE IS EASY FOR A SUBSCRIBER TO STEAL POWER FROM IT, AND THE EMPLOYEES OF THE POWER COMPANY MAY PRIVATELY COLLABORATE WITH A SUBSCRIBER TO STEAL POWER FROM THE ELECTRIC METER AND THIS CAUSES A GREAT LOSS TO THE COMPANY.</p> |
