Remote detection device for water, gas, or electricity using power line communication

The present invention relates to a remote meter reading device using a power line, and more specifically, the electricity consumption, water consumption, and / or gas consumption consumed in a large group house such as an apartment can be aggregated and retrieved in the guard room and the management room. The present invention relates to a remote meter reading device using a power line that is useful for management and can prevent unnecessary waste of resources.

Conventionally, consumer goods such as electricity, gas, or water are settled on a monthly basis, and the meter reader reads monthly to check the amount of usage, and remote meter reading is activated to solve such inconvenience. The remote meter is equipped with a meter that can quantify the amount of electricity used in each household by attaching to the meter installed in the pipe where each material is supplied or embedded in the meter itself. In this case, the meter reading and usage fee collection agencies received usage data from the meter reading department and charged the usage fee for the item at the end of the month or on a set date.

However, in the conventional method of transmitting the usage data, each user's household could not know the amount of electricity, gas, and water used by them, so they could not recognize the usage until they had to check the meter directly or deliver a bill for the user. . Especially in large apartments, charges for electricity, water, and gas are used in the security office or the management office. Also, when a bill is issued, it is possible to notify each customer and to manage the bills. In some cases, a dispute arises between the employer and the supplier, and it is difficult to resolve the dispute because the usage cannot be directly inspected in the apartment management office or the security office. Furthermore, there is no way to detect abnormally used consumers, such as apartments or guard rooms, if there is gas, water, or electricity left in use for a long time in an apartment. There may be a chargeback for usage. It is also a factor in creating complaints of residents' negligence of management or security.

The present invention was devised to solve the above problems, and an object of the present invention is to calculate the electricity consumption, water consumption, and / or gas consumption in each household in a large group house such as an apartment in the security office or the management office. By using the power line to collect and process the data, the management can faithfully solve complaints and complaints of the residents, and to provide a remote meter reading device using the power line to eliminate unnecessary waste factors.

Another object of the present invention is to provide a remote meter reading device using a power line that is easy to build communication facilities and low cost by receiving the usage data by using a power line rather than a dedicated line such as a cable.

Hereinafter, referring to the accompanying drawings, a remote meter reading device using the power line of the present invention will be described in detail.

1 is a schematic configuration diagram of a remote metering device using a power line of the present invention, for example, the electric metering unit (a), gas metering unit (b), water metering unit (c) installed in 101 of apartment A The converter 10 is connected to all the meter reading unit of the) and receives the usage data, the data processing unit 20 is connected to the converter 10 through the power line and receives the usage data, and the data from the data processing unit 20 A monitor 30 for visually outputting data displayed in a format and a printer 40 for printing usage data on a sheet are displayed.

The converter 10 is a remote meter reading device for measuring the electricity, water and gas used in each home of the apartment (attached to the meter or meter attached to convert the amount of use to a specific data format to output the amount of usage data) Usage data is sent from. In other words, in the present invention, by using the remote metering devices already installed in each home of the apartment to aggregate the usage data, it is possible to read the meter separately from KEPCO or the water supply establishment. Or it is obvious that it is possible to install metering devices that directly generate usage data.

When using the electric metering part (a), gas metering part (b), and water metering part (c) already installed, it is necessary to check the data format outputted from each metering part and to set the data to be extracted accordingly. It is important. Usage data input from each meter reading unit is added to the data processing unit 20 is added to the identification data to identify each customer in the converter (10). At this time, data is transmitted through a power line, not through a dedicated line or a telephone line. Therefore, the device of the present invention has a feature that can be configured at low cost without the extra cost of installing a dedicated line. The power line communication transmitter 104 is embedded in the converter 10 to enable power line communication to transmit data through the power line.

Usage data of each household transmitted through the power line is received by the data processing unit 20 and then stored in a specific database format. The data processing unit 20 classifies and processes the used data to be identified for each household, and calculates and outputs the usage and usage fee or hourly usage and usage fee on a daily, weekly or monthly basis. The output can be output through the monitor 30 or through the printer 40.

Figure 2 is a block diagram of one embodiment of the converter 10 of the present invention for performing the function as described above. As shown in the drawing, the converter 10 inputs from the detection interface unit 101 and a detection interface unit 101 which detects and reads each usage data inputted from the electric meter unit, the water meter unit, or the gas meter unit. A control unit 102 for classifying and storing the used usage data into a memory, a modulation unit 103 for modulating the usage data output for transmission from the control unit 102 into a specific pulse form, and the modulation unit ( And a power line communication transmitter 104 for transmitting the modulation data input from the 103 through a power line.

The detection interface unit 101 converts the usage data input from the electric metering unit (a), the gas metering unit (b), and the water metering unit (c) to be recognized by the controller 102 of the present invention. It plays a role. In other words, since the data format for detecting the amount of usage detected by the electric meter reading unit (a) is different depending on the type of each meter reading device, it is for recognizing data currently output from the meter reading unit and reading the current amount of usage. This can be generated in a number of ways so that the data format generated by the electrical metering unit (a) (or the gas metering unit (b) and the water metering unit (c) is the same) is not recognized by other devices or other institutions. Therefore, it is required to recognize the data format of the meter reading unit and convert the data.

Usage data recognized by the detection interface unit 101 is input to the control unit 102. The control unit 102 converts the input usage data into a unique data format used in the apparatus of the present invention. The data format is a data format that includes data such as the house, lake, and usage of the apartment in which the usage data is generated.

4 is an embodiment of the data format generated by the control unit 102 of the converter 10 of the present invention, D1 is the same number of apartments, D2 is the apartment lake, D3 is the electricity consumption data, D4 is the water consumption data, D5 is Gas usage data, D6, is an example of a data format in which a unique identifier is recorded.

The data sorted by the data format set by the controller 102 is transmitted to the data modulator 103. The data modulator 103 modulates the data in pulse form. The usage data modulated in the form of pulse is transmitted to the power line communication transmitter 104 and transmitted through the power line. The power line communication transmitter 104 modulates and outputs a frequency to transmit data through the power line. The data modulator 203 modulates the usage data into a pulse code signal, and the power line communication transmitter 104 transmits the modulated pulse signal in a code division multiplex (CDMA) scheme.

The usage data signal transmitted through the power line as described above is input through the power line connected to the data processor 20. A block diagram of an embodiment of the data processor 20 is shown in FIG.

As shown, the data processing unit 20 receives a signal input from the converter 10 through the power line and the power line communication receiving unit 201 for detecting the modulated usage data and the power line communication receiving unit 201 A data demodulation unit 202 for demodulating usage data, a control unit 203 for processing usage data input from the data demodulation unit 202 in a specific database format, storing the usage data in a database 206 and controlling the overall apparatus; A monitor driver 204 for outputting data on the monitor 205 screen according to the drive signal output from the controller 203, and a printer for printing usage data according to a control signal output from the controller 203 ( And a printer driver 205 for driving 206.

The power line communication receiver 201 separates a usage data signal in a pulse signal state from signals input through the power line. The separated usage data is again demodulated into data corresponding to the pulse code while passing through the data demodulator 202. The demodulated usage data is input to the control unit 203. The controller 203 stores the input usage data for each building and lake. The stored form may be stored in a different format depending on the database program. Therefore, the control unit 203 is loaded with the database control program and driven. The usage data may be generated and transmitted regularly at regular intervals, for example 1 hour or 24 hours. This measurement period can be set in the converter 10 that receives the usage data. In other words, the control unit 102 of the converter 10 sets the data input time programmatically and automatically reads the usage data and transmits the usage data to the data processing unit 20 when the corresponding time is reached.

With the electricity, water, and gas consumption data of each household stored in the database 206 as described above, the manager outputs electricity, water, and gas consumption of the household when a user, that is, a housewife of each household, requests. In FIG. 4, an electric charge, a water charge, or a gas charge and a charge total at a specific time point are displayed. In the case of electricity, this rate calculation can be calculated by applying a time-based rate system, such as a late night discount, in essentially the same manner as in calculating KEPCO usage fees, which is achieved by changing certain parameters of the rate calculation. 6 illustrates a data collection and processing process as described above. Usage data stored in the database 206 can be output in various forms by a query of the database, it is possible to extract the results so that the user can easily recognize.

As above, it is possible to store and output data on electricity, gas, and water usage for each user's home in the apartment management room or security office. It is the basis for solution.

In the present invention, the manager or security guard can check the amount of electricity, gas, and water used by each household to investigate the usage of the empty household without a current family, thereby preventing unnecessary waste of gas, electricity, or tap water. .

Although the present invention has been described with reference to only one home, Building A 101, the converter 10 is installed in each home, so that it is possible to simultaneously receive and use database data used in tens or hundreds of homes. . At this time, the identification of the usage data in each home is possible by assigning apartment buildings, lakes, and specific identifiers in the respective converters 10.

As described above, according to the present invention, the electricity consumption, the water consumption, and / or the gas consumption consumed in a large group house such as an apartment can be aggregated in the guard room or the management room, so that data can be collected using the power line to prevent unnecessary waste. There is an advantage that can be collected and processed.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the present invention, and such modifications or changes belong to the appended claims. .
