KR970076336A - Code pre-paid energy meter information device and its method - Google Patents

Abstract

The present invention relates to a pre-paid energy metering information device of a code type in which a user code device is installed in each customer and a cost process for each energy, that is, electricity, water, gas, hot water, A first step of setting an amount of energy used by a current user and a usage fee, displaying an energy usage balance remaining in the user code device unit on the LCD, and comparing the corresponding energy fee used by the user Wow; A second step of initializing the energy usage amount and the usage amount added to the new month if the corresponding energy fee is settled in the first step; If the energy usage charge is not settled in the first step, the energy usage charge is settled on the basis of the current energy usage amount, the adjusted amount is changed to the current month value of the energy, A third step of comparing and retrieving the energy of the balance of the apparatus and the corresponding energy of the blocking differential ratio rate threshold value; If the remaining amount of the current user code unit is less than the threshold value in the third step, the power is cut off and the supplied power is cut off; And a fifth step of opening the load of the energy when the remaining amount of the current user code unit is larger than the threshold amount and displaying the current usage amount and the usage amount of the corresponding energy on the LCD in the fourth step, Unlike a method of setting a fee by receiving an IC card from a card reader, a method of setting a fee in the case of a code that has been concatenated through a code comparison unit after receiving a code using a code input unit, It is not necessary to manage the medium and the user can input the code into the user code device which is given the code by using the communication network at home by using the method of directly inputting the code, There is an effect that energy can be used irrespective of time and place constraints.

Claims (3)

The energy meter information system includes a user code unit installed in each customer and configured to preprocess each energy usage charge by a user's code input. 2. The system of claim 1, wherein the user code unit comprises: a main CPU for first determining whether to charge and block energy; a secondary CPU for converting pulses received from each energy meter into usage amounts; A pulse controller for detecting and sequentially processing pulses; a blocker for operating according to whether or not each energy is cut off from the main CPU; a code input unit for inputting a code given in advance by the user; And a code comparing unit for comparing the code stored in the EEPROM with a code received at the time of paying the prepaid code, an EEPROM for storing the important data during power outage, a communication unit for communicating with the meter reading computer of the energy provider, A set key for enabling each energy cutoff as a user, A display unit, and a power supply circuit, a power failure during operation energy prepayment metering device information of the code system, characterized by consisting of a backup battery for supplying power to the circuit for the codes. A first step of setting a usage amount and a usage fee of the energy currently used by the user, displaying an energy usage balance remaining in the user code device unit on the LCD, and comparing the energy fee adjustment used by the user; A second step of initializing the energy usage amount and the usage amount added to the new month if the corresponding energy fee is settled in the first step; If the energy usage charge is not settled in the first step, the energy usage charge is settled on the basis of the current energy usage amount, the adjusted amount is changed to the current month value of the energy, A third step of comparing and retrieving the energy of the balance of the apparatus and the corresponding energy of the blocking differential ratio rate threshold value; If the remaining amount of the current user code unit is less than the threshold value in the third step, the power is cut off and the supplied power is cut off; If the remaining amount of the current user code unit is greater than the threshold value in the fourth step, the load of the corresponding energy is released and the current usage amount and the used amount of the corresponding energy are displayed on the LCD. Code pre-paid energy metering information method. ※ Note: It is disclosed by the contents of the first application.
