Description

[0001] The present invention relates to a remote meter reading system and a remote meter reading network using a QR code,

The present invention relates to an automatic meter reading system using a QR code and a method of configuring an automatic meter reading network, and more particularly, to a data collecting apparatus that calculates an electric charge using a power consumption received from a plurality of meters, And a plurality of meters and a transformer each having a QR code so that the system relationship between the plurality of meters and the transformer is matched with the distribution diagram, The present invention relates to a remote meter reading system and a method of configuring a remote meter probe network using a QR code that can easily configure and manage a remote meter probe network.

As the use of electric stoves, electric plates and so on is rapidly increasing due to the abnormal weather wave caused by the global climate change, so-called charge bombs are a big social problem, have.

If you are expecting such a price bomb, you may want to inform the energy consumer in advance, how much energy you are using in your home, and how much you will be charged for the amount of energy you have used so far. It is common to connect the communication between the meter and the in-home display (IHD) to display the related information from the meter to the display device. However, in this case, in order to transmit various information such as the charge information and the usage amount information voluntarily and at a desired time to each display device installed in the living room from each meter installed on the outer wall such as under the eaves, It is expected that an astronomical cost will be required to implement a smart grid because the display device must include a related communication function in order to receive and display information transmitted from the meter.

Also, when designing the power line communication network for remote survey of about 18 million households, which is the infrastructure (infrastructure) of these various services nationwide, it is essential to perform technical review considering the system with low voltage distribution line in the field, manual design using drawings, It takes a lot of time and manpower. Although design automation using advanced technology is progressing in the whole industry, it is difficult to automate complete design due to the technical characteristics of power line communication such as various propagation characteristics in the field of power line communication network design.

As a method of collecting data of a meter from a remote communication network, a power line communication method (PLC: Power Line Communication) using a conventional electric line is applied instead of a separate communication network from a low-voltage distribution line section, that is, a transformer to a consumer meter And a method of using an optical network or a wireless network from a transformer to a meter reading server, that is, a separate main network is mainly used.

In this case, a data concentrator (DCU: Data Concentration Unit) with a power line communication module is installed on the transformer side, and a power line modem for communication with the DCU is installed on the meter side to transmit the metering data to the data concentrator through the power line. The collected data is transmitted to the server side through the main network.

In this way, DCU's role is to communicate with dozens of metering-side modems, which is a key device of power line communication, within a very short time. Therefore, DCU must have related information and communication modem information of meter Remote telemetry can be performed by opening a communication network only if you have a remote server.

Usually, in this case, when all the devices (server, DCU, modem, meter) are installed and power is turned on, the address (IP address and MAC address) of the modem is automatically transferred to the DCU and registered in the internal memory of the DCU. The modem address is sent to the server and the server matches the remote meter customer database (customer and meter number) with the modem address. Generally, this auto registration procedure is about 70 ~ 80% success rate, and the remaining 20 ~ 30% after installing the modem and DCU, check the location where the auto registration is not done in the server, The DCU must register with the DCU. In this case, a cable or wireless communication is connected to the DCU installed at the bottom of the transformer to perform database operation with the notebook. Thus, it takes a lot of time and manpower to manually open the remote meter reading network. According to the government's Smart Grid policy, about 260,000 units, about 70% of the total installed capacity of 8,800 units, will be required to visit the site in order to perform manual operation manually.

The present invention will now be described in detail with reference to the accompanying drawings. Hereinafter, a repeated description, a known function that may obscure the gist of the present invention, and a detailed description of the configuration will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

1 is a view schematically showing a remote meter reading system using a QR code according to an embodiment of the present invention.

Referring to FIG. 1, an automatic meter reading system 100 using a QR code according to an exemplary embodiment of the present invention transmits an electricity bill and a power consumption amount as a result of remote meter reading to a data receiving apparatus 200. The data receiving apparatus 200 may be a set top box or a smart phone app server. An operation example of the remote meter reading system 100 using the QR code according to the type of the data receiving apparatus 200 will be described in detail with reference to FIG.

The remote meter reading system 100 using the QR code according to an embodiment of the present invention may include a meter 101, a transformer 102, a power distribution diagram management unit 103, and a data management unit 104. The remote meter reading system using the QR code shown in FIG. 1 is according to an embodiment, and the blocks shown in FIG. 1 are not all the blocks, and in some embodiments, some blocks may be added, changed or deleted .

The meter (101) measures the power consumption of a consumer using electricity. The meter (101) may be a plurality of meters (101) provided in a plurality of customers and each may have a different Quick Response (QR) code. A QR code is a code having information in two directions, that is, a code having information in two directions, thereby dramatically increasing the amount of information that can be recorded compared to a bar code having information in only one direction. QR codes are used in various forms such as mobile coupons, store information, and corporate site information. Furthermore, individual information is distributed and distributed, and it is easily recognized by using a smart phone. Has attracted attention as an information medium. The QR code of the meter 101 may be the same as the QR code attached to the bill.

The transformer 102 converts the electricity produced by the power plant to a low pressure for supply to the customer since it is high pressure. The transformer 102 is connected to the meter of the customer and calculates the electricity rate using the amount of electricity received from the meter 101 and transmits the electricity rate and the power consumption to the data receiving device, Data Concentration Unit (not shown).

In one embodiment, the DCU includes a modem unit (not shown) for communicating with the plurality of meters to receive a power usage of a plurality of meters, transmit an electricity rate and the power usage, and a power bill and a power of the plurality of meters And a processor (not shown) for calculating the electricity rate using the usage amount and controlling the electric fee and the power consumption to be transmitted to the data reception device.

In the remote meter reading system 100 according to an embodiment of the present invention, the DCU can process data of a plurality of meters 101, thereby solving the problems of the related art.

In the past, there was a remote meter reading system, which is mainly used in the US and Europe, which is a smart meter, which was established early on as a smart grid concept. According to this method, the usage amount and the charge are displayed on the LCD (Liquid Crystal Display) mounted on the meter by converting the electricity consumption amount and the gas usage amount into the fee, or a separate display device (IHD: In Home Display to display the usage and the charge so that the customer can check the meter from time to time. In this case, the meter not only displays the power consumption, but also has a high-performance processor and memory for displaying the charge to the IHD while communicating with the modem in the home, There is a problem in that a separate processor cost must be added to the meter in addition to the meter.

In addition, there is a method in which a kind of gateway is installed in a home in a way that is similar to the above method and the principle is used recently, and the metering data and the charge information coming from the meter are directly converted and displayed on the IHD using the wireless method . The gateway is equipped with two modems such as a wired modem such as a PLC and a wireless modem such as ZigBee. In addition, the gateway incorporates a separate processor for data processing for each communication method and conversion of metering data. The reason for introducing the gateway is that if the modem of the meter is a wireless modem, if the communication network is configured in the same manner as described above, the radio frequency passes through the wall and a considerable attenuation occurs and the failure rate is high. According to the method using the gate method, once the modem of the meter and the gateway modem in the home are used as a power line communication (PLC) method, the measured data is sent to the home without loss and the signal is converted into wireless in the home gateway, And the data is transmitted to the IHD installed within about 5 meters of the IHD. The disadvantage of this method is that there is a separate cost for the processor in the meter side as well as a considerable cost in constructing the gateway, and the IHD also incorporates a wireless modem and is equipped with a battery for driving the modem, It should be replaced.

Referring back to FIG. 1, the DCU of the transformer 102 in the remote metering system 100 according to an embodiment of the present invention can process data of a plurality of meters 101. That is, according to one embodiment, in the remote metering system 100, the transformer 120 installs a DCU equipped with a power line communication (PLC) modem and a processor, and the DCU includes, for example, about 20 To communicate with 200 meters to read the power usage of multiple meters from the transformer. At this time, the DCU converts the fee table and the power usage of about 20 to 200 households, converts the bill into a charge, and transmits the fee to the data receiving apparatus 200.

This approach compensates for the disadvantages of the costly conventional approach by installing a processor or installing a separate gateway for about 200 meters each meter.

The transformer 102 may have a QR code similar to that of the meter 101 and has a different QR code from the meter 101 in order to distinguish it from the meter 101. [

The power distribution diagram management unit 103 manages power distribution diagrams showing the power distribution lines of the meter 101 and the transformer 102. [ The power distribution diagram shows a distribution line showing how the meter 101 and the transformer 102 are actually connected. The connection relationship between the meter 101 and the transformer 102 can be grasped at a glance through the power distribution diagram, and the power distribution diagram management unit 103 performs management such as creation, modification, or deletion of such power distribution diagram. The power distribution diagram management unit 103 may be in the form of a power distribution diagram server.

The data management unit 104 includes a QR code of the meter 101 and a QR code of the transformer 102 and uses the QR codes of the plurality of meters and the transformer 102 to calculate the system relationship between the meter 101 and the transformer 102 And corresponding data generated in association with the power distribution diagram. The system relationship between the meter 101 and the transformer 102 refers to a correlation that enables checking which meters 101 are connected under the specific transformer 102. [ A plurality of meters 101 and a transformer 102 each have a different QR code and can be identified using a QR code so that the meter 101 and the transformer 102 can be identified using the QR code. The system relationship can be made to correspond to the distribution diagram, and the data management unit 104 manages the corresponding data generated through such a correspondence. In one embodiment, the data management unit 104 may be included in the remote meter reading server.

2 is a view schematically showing a remote meter reading system using a QR code according to another embodiment of the present invention.

2, an operation example of an automatic meter reading system using a QR code according to the type of the data receiving apparatus 200 in FIG. 1 will be described. In FIG. 2, the same reference numerals as those in FIG. 1 denote the same components, and therefore the description of FIG. 1 will be applied mutatis mutandis.

As described in FIG. 1, the data receiving apparatus may be a set-top box 201 or a smartphone application server 202. The set-top box 201 receives the electricity bill and the power consumption and displays the received electricity bill on the TV 203 of each customer. The smartphone application server 202 receives the electricity rate and the power consumption and transmits the electricity rate to the smartphone 204.

First, an embodiment in which the data receiving apparatus is the set-top box 201 will be described. Data is transmitted from each meter 101 to the DCU of the transformer 102 via the modem. In the DCU, the metering data transmitted from the meter 101 is converted into a fee, and the data is transmitted to the set-top box 201 as a modem And the set-top box 201 displays it on the TV 203 screen. On the screen, various information related to energy such as energy usage and fees can be displayed when a television user switches to a remote controller or the like with a preset channel or with a caption flowing from an image.

Next, an embodiment in which the data receiving apparatus is the smartphone application server 202 will be described. When the DCU sends data to the smartphone application server 202, the customer can access the smartphone 204 at a desired time to view his / her power-related information stored in the DCU. At this time, the customer can access the smartphone 204 using the QR code. That is, when the customer recognizes the QR code of any one of the meters 101 via the smartphone 204, the DCU receives the power consumption of the meter 101 in which the QR code is recognized, And transmits the electricity rate and the power usage amount to the smartphone application server 202. The smartphone application server 202 transmits the electricity rate and the electric power usage amount to the smartphone 204 again.

The DCU transmits a warning message to the set-top box 201 or the smartphone application server 202 when a power consumption exceeding a predetermined level is received from the meter 101 or a fee exceeding a certain level is calculated, ) Or the smartphone 204 to confirm the warning message. This makes it possible to prevent the electric bill bomb from being imposed on the customer of the customer in advance.

In addition, it will be possible to utilize the flow from the DCU to the TV to survey the broadcasting companies. In this case, the DCU receives the opinion survey results collected from the TV 203 of each of the above-mentioned customers from the set-top box 201 and transmits the same to the broadcasting public opinion server 205. In other words, the broadcasting company can send the questionnaire items to all households or public opinion specimens through the broadcasting company public opinion server 205. The data flows are transmitted to the broadcasting company public opinion server 205, the transformer 102, the loader 101, (201) -TV (203), and the viewer answers the questionnaire with the remote control. The results of the survey may be transmitted to the broadcasting company survey server 205 via the set top box 201 and the meter 101 via the DCU processor of the transformer 102. Of course, even in this case, the DCU can recognize the IP address of individual households coming from the television and transmit the contents of the survey response accurately to the broadcasting server. In other words, since the meter data must be transmitted to the public company survey server and the survey result should be transmitted to the broadcasting company public opinion server, each meter and the television side can have a separate address (IP address) . According to this, it is possible to utilize the PLC-based remote meter reading network for each household for the smart grid for the public opinion survey, so that the presidential election, the parliamentary election, In a limited poll, it is possible to extend the sample to all households. In addition, when a PLC-based remote meter-reading network is established in all households nationwide, it is possible to conduct surveys on the entire population (the general public), which can improve the accuracy of understanding public opinion.

3 is a view for explaining a problem occurring in the conventional remote meter-reading system.

1 and 2, a remote meter reading system using a QR code according to an embodiment of the present invention has been described in detail. The remote meter reading system using the QR code according to an embodiment of the present invention can solve the problem occurring in the conventional remote meter reading system using the QR code. In order to explain this, the conventional remote meter reading system Describe what problems will occur.

Conventionally, when designing the remote meter network, it is necessary to identify the transformer identifier (ID), the DCU identifier (ID or IP address), the modem identifier (IP address or MAC address) and the meter identifier (ID) We have been manually registering the matching database to the server and the DCU. In order to minimize the hassle of such manual operation, a method of automatically configuring the remote meter reading network has been proposed. That is, when the power of the modem of the DCU 302 and the meter 303 is turned on first and each modem sends out a power line communication signal, each modem 303 of the meter 303 takes a power line and sends a signal to the transformer 301 of the upper stage send. The DCU 302 in the transformer 301 receives such a meter modem signal and automatically grasps the addresses of the submerged meters 303 to the DCU 302 of the transformer 301, And transmits it to the remote meter reading server 305 via the communication network 304 while registering in its own memory so that the meter, the customer, and the transformer database are automatically matched. When the modem and the DCU are powered only by the automatic flow, the addresses are matched automatically so that it is not necessary to perform an address matching operation in the field. However, as shown in FIG. 3, the meter 303 and the modem information The DCU 302 may be connected to the DCU 302 of the transformer 301 by way of the power line, but it may be transferred to another DCU in the neighborhood by a wire or wire 306 connected to each transformer 301, There is a tendency that confusion occurs. In such a case, the remote meter reading server 305 may cause confusion in the database management, and in some cases, it is expected that the error will not be noticed. Due to this error, the number of meters 303 under the transformer 301 connected to the DCU 302 is actually larger than that of the bite meter, thereby reducing the accuracy of the surveillance surveillance (surveillance customer surveillance), transformer load surveillance, and the like. This is because, when the meter data on the side of the other transformer rises through the wire line or the neutral line 306, it is judged that the transformer 301 is overloaded or that the customer side erroneously judges that a short circuit or the like is occurring.

In order to solve the problem described with reference to FIG. 3, the power distribution diagram management unit 103 and the data management unit 104 of the remote meter reading system using the QR code described in FIG. 1 and FIG. Concretely, the reconciliation process is performed by double registration through a join line, a database error of a distribution drawing server, a human error which occurs in the process of inputting a database in a remote meter reading server, a transformer DCU side) and it is registered in the transformer (DCU side) other than the one on the DCU side.

To this end, the user recognizes the QR codes of the plurality of meters 101 and the transformer 102 via the smartphone and transmits them to the data managing unit 104 through the smartphone app server. Then, the data management unit 104 checks whether the system relations of the plurality of meters 101 and the transformer 102 match with the distribution diagram, and if they do not match, corrects the corresponding data of the data management unit 104 to match do. The power distribution diagram management unit 103 can modify the power distribution diagram so that the relationships between the plurality of meters 101 and the transformer 102 do not match the power distribution diagram. In this way, the system relationships of the plurality of meters 101 and the transformer 102 can be matched.

4 is a flowchart illustrating a method of configuring an automatic meter reading network using a QR code according to an embodiment of the present invention.

Referring to FIG. 4, when a method of configuring an automatic meter reading network using a QR code according to an embodiment of the present invention is started, a different Quick Response (QR) code is provided to a plurality of meters for measuring power consumption of a plurality of customers (S401). The QR code for such a meter may be the same as the QR code attached to the bill.

Then, a QR code different from the plurality of meters is allocated to the transformer (S402). The transformer may include a data concentrator that calculates an electricity rate using the amount of electric power received from the plurality of meters, and transmits the electricity rate and the electric power consumption to the data receiving device.

After assigning the QR codes to the plurality of meters and the transformers (S401 and S402), a distribution diagram showing the plurality of meters and the distribution lines of the transformers is generated (S403). Then, in step S404, a plurality of meters and a QR code of the transformer are used to generate corresponding data by associating the system relations of the plurality of meters and the transformer with the distribution diagram.

The remote meter reading network configuration method using the QR code shown in FIG. 4 has a configuration similar to that of the remote meter reading system shown in FIG. 1, so that the description in FIG. Also in FIG. 4, as in FIG. 1, each step of the flowchart shown in FIG. 4 is not a necessary step in all steps, and some steps may be added, changed or deleted in another embodiment. Further, the steps of the flowchart are not limited to the illustrated order, and the order may be modified or changed as necessary.

FIG. 5 is a view for explaining a reconciliation process for solving the problem in designing the conventional remote meter-reading system described in FIG. 3. After all the steps of the remote meter-check network construction method described in FIG. 4 are performed, have.

First, the smartphone recognizes the QR codes of the plurality of meters and the transformer and transmits them through the smartphone app server (S501). The system relationship between the plurality of meters and the transformer can be grasped. Then, it is checked whether the system relations of the plurality of meters and the transformer match the distribution diagram (S502).

If the system relations of the plurality of meters and the transformer do not agree with the distribution drawings in step S502, the corresponding data is corrected so as to match with each other (S503), and the distribution diagram is corrected so as to be matched (S504).

If the system relations of the plurality of meters and the transformer coincide with the distribution diagram in step S502, the reconciliation operation is ended without modifying the corresponding data or the distribution diagram.
