More particularly, the present invention relates to a HMI providing system for measuring a watt-hour meter capable of real-time measurement of metering data in a plurality of watt-hour meters using a standard protocol.

Generally, a meter is installed in a consumer building such as a home or a factory to indicate the usage amount of electricity, gas, and water. The supplier checks the amount of the supply through the meter reading device of the prisoner and charges the usage amount.

The supplier regularly inspects the meter installed in the customer 's building for charging. Conventionally, the meter reading apparatus judges each meter reading device with the naked eye, records the numerical value by hand or inputs a key to the hand terminal. The supplier must accurately measure the usage of the detainee and impose the correct charge. However, in the conventional case, there is a possibility that a mistake may be mistakenly recorded or inputted, thereby causing a wrong fee to be charged.

At present, researches on methods for accurately measuring the amount of use using a meter reading device are actively being carried out.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.

Generally, an automatic meter reading system (AMR) is a system that converts measurement results from an object at a remote location to an electrical signal, transmits data through a communication network, and processes the data in a computer.

Remote meter reading has been developed as a new information communication service due to the development of communication technology, sensing technology and computer technology. Recently, it has been widely used in pollution monitoring, crime prevention, disaster prevention, electric power, water supply and gas system.

Such an automatic meter reading system is classified into a wireless system having no communication line and a wired system having a communication line according to the communication system used. The wired method is classified into a power line method, a CATV cable method, a dedicated line method, and a telephone line method depending on the type of a communication line to be used.

Among the wired methods, the power line method is a method using power line communication (PLC), in which a power company uses a power line used as a signal transmission path to supply electricity to a home, a factory, or an office .

Power line communication is a method of communicating data by a power line using a commercial AC signal as a transmission medium. Since a sine wave of 60 Hz and a communication signal (for example, several tens of KHz) are multiplexed and transmitted at the same time, Communication is possible anywhere.

The client is interconnected with a plurality of data collection devices through a data communication network (e.g., a backbone network, a private network, and an Internet network) provided to perform data communication based on TCP / IP (Transmission Control Protocol / Internet Protocol).

The client transmits and receives data in real time to and from the data collection device through the data communication network, and it is possible to monitor the power status of each customer in real time.

In addition, the client receives meter reading data of each customer from the data collection device in real time. Based on such meter reading data, the power state of each customer, for example, power failure, electrical conduction, leakage current state, etc., is analyzed and provided to the manager. Here, the meter reading data may be a sum of all the electric power consumed by the monthly, weekly, nighttime, date, and time of all the consumers assigned to one data centralizing apparatus, As well as any data that can be used to determine the power quality of each customer.

FIG. 1 is a block diagram showing a conventional meter reading system including a data collecting apparatus equipped with multiple protocols.

Referring to FIG. 1, the conventional remote meter-reading system includes a facility-meter-dedicated data collection device 15 for collecting meter-reading information of each facility meter, a watt-hour meter 16 for measuring the accumulated power consumption per each household, And a user terminal 17 for controlling the device 15.

The remote meter reading system includes a plurality of meters (10) for measuring gas, water, hot water, and heating usage of each household and transmitting the meter reading information to the multi-protocol on-board data collecting device (15). The plurality of meters 10 are produced by different manufacturers, and different protocols can be used.

For example, the plurality of meters 10 may include a B-type communication type gas meter 11, a C-type communication water meter 12, and a B-type communication type water meter 11, respectively, for transmitting data in a leased line method (RS- D company communication type hot water meter 13 and E company communication type heating meter 14. [

The B communication gas meter 11, the C communication water meter 12, the D communication hot water meter 13, and the E communication heating meter 14 can use different unique protocols. For convenience, only a configuration capable of checking electricity, gas, water, hot water, and heating of one generation is shown, but the present invention is not limited thereto.

At this time, the data collecting device 15 is equipped with a plurality of protocols for gas meter, water meter, hot water meter, and meter reading of the heating meter. That is, the data collecting apparatus 15 may be provided with a meter reading protocol corresponding to each of gas meters, water meters, hot water meters, and heating meters of different manufacturers (B, C, D, E, protocol) are mounted in multiple.

The watt-hour meter 16 measures the cumulative power consumption of each household, and receives meter reading information such as gas, water, hot water, and a heating meter from the multi-protocol on-board data collecting device 15 by digital communication in TTL communication, The meter reading information can be sequentially displayed on the device.

The user terminal 17 can execute the upper application for receiving, reading, storing, maintaining and displaying the meter reading information collected through the RS-485 communication from the data collecting apparatus 15 equipped with the multi-protocol .

That is, in the related art, the data collecting device 15 has been linked through the data collecting device 15 directly connected to the various kinds of the measuring devices 10. In this case, the data collecting device 15 merely reads the meters / watt- Only pure weighing values were used.

In the conventional remote meter-reading system configured as described above, collecting data using the remote meter reading is mainly used for measuring and charging the usage amount of the user from the meter, maintenance or maintenance of the equipment according to the usage analysis.

At this time, since the data collecting device 15 and the meter 10 are directly connected to one another, they use separate protocols. The meter 10 and the data collecting device 15 can not be used because the previous meter market system is only in a 1: 1 relationship with the individual protocols, in terms of interoperability between the data collecting device 15 and the meter 19. [ The data collecting device 15 must be implemented at the level of the data collecting center in order to consider the interoperability between the data collecting centers. As a result, there is a problem that expensive installation cost and maintenance are difficult to operate the remote meter reading system.

Hereinafter, a system for providing a HMI for measuring a watt-hour meter according to some embodiments of the present invention will be described with reference to FIGS. 2 to 6. FIG.

Referring to FIG. 2, the HMI providing system for measuring a watt-hour meter according to some embodiments of the present invention includes a client 100, a data collecting apparatus 200, and a meter 300.

The meter 300 is an apparatus for measuring the accumulated amount of usage in accordance with the use of services such as electric power, water, gas, hot water, and heat. That is, the meter 300 measures electric power, water, gas, hot water, heat, etc. according to IEC 62056 international standard. Meter 300 may be a DLMS-based meter. At this time, the Device Language Message Specification (DLMS) is a communication protocol for communication compatibility of a meter regarding data modeling, message composition and transmission method of a meter according to IEC 62056 international standard.

The data collection device 200 is a device for collecting data from the meter 300 and can transmit collected data according to a request of the client 100 through a wired / wireless communication network. The data collection device 200 can measure the metering data in real time, control the operation of the watt hour meter, and change the set value. The data collection device 200 can operate as a server of the client 100. [

The data collection period of the data collection apparatus 200 is, for example, for data collection for at least once a month in the case of simple monthly inspection, The minimum amount of data collection times can be changed according to the accuracy and the like. The collected data may be transmitted to the client 100 for billing and management according to the usage amount analysis for each period and the monthly usage amount, and may be processed.

The client 100 can process the metering data collected through the data collecting apparatus 200. Herein, the client 100 may be a computer, a UMPC (Ultra Mobile PC), a workstation, a netbook, a PDA (Personal Digital Assistants), a portable computer, a web tablet, a mobile phone, a smart phone, an e-book, a portable multimedia player (PMP) device capable of transmitting and receiving information in a wireless environment, a variety of devices constituting a home network Electronic devices such as one of the electronic devices, one of the various electronic devices that make up the computer network, one of the various electronic devices that make up the telematics network, the RFID device, or one of the various components that make up the computing system It can be one of various components. However, the present invention is not limited thereto.

3 is a diagram showing a structure of a HMI providing system for measuring a watt hour meter according to some embodiments of the present invention.

Referring to FIG. 3, a system for providing a HMI for measuring a watt-hour meter according to some embodiments of the present invention includes a client 101 and a server 201.

The client 101 corresponds to the client 100 described with reference to Fig. 2, and the server 201 corresponds to the data collection device 200 or the meter 300 described with reference to Fig. In the following, we will omit duplicate content and explain the difference.

The server 201 may be generally configured by applying the IEC 62056 communication protocol to one or more watt-hour meters. The watt-hour meter basically makes a physical connection to the server 201 through a serial or optical communication medium, and the watt-hour meter can configure a client program 1000 and a multi-drop system configuration Can be achieved.

The client 101 may include a memory for storing the client program 1000 using the measured data and the data at the server 201, and a processor for executing the client program 1000. The client program 1000 is executed by the processor of the client 101 and can display the results on the screen included in the client 101. [ This will be described later with reference to FIGS. 5 and 6, which are a detailed description thereof.

The client program 1000 can exchange communication services through a communication system defined by IEC 62056 and a watt-hour meter, and can measure metering data of the watt-hour meter in real time.

The IEC 62056 communication protocol standardizes the functions of the watt hour meter, including how to transfer the weighing data that the watt hour meter has, as well as how to access registers, clocks, schedules, and profiles. As a result, the watt-hour meter can be operated in a standard way regardless of the manufacturer, and it is possible to define the class object so that a complete watt-hour meter can be configured. The data types used and the various objects are made up of the customer's needs and the manufacturer's strategy, covering a range of products from simple household wattmeters to complex commercial meters and watt-hour meters for distribution and transformation.

In some embodiments of the present invention, communication with the watt hour meter is based on the client / server paradigm shown in Fig. 3, wherein the watt hour meter can serve as the server 201. [ Communication in this environment occurs between the client 101 and the server 201, and the server 201 and the client program 1000 can be remotely provided through a message exchange service.

The client program 1000 can communicate with a watt-hour meter through a port for communication and an environment setting for connection setting. The client program 1000 provides the items of the parameters provided by the watt-hour meter on a screen in the form of a list, and when the user selects an item to be measured, the measurement result value can be provided in real time.

At this time, the client program 1000 may change, modify, and supplement the function of the meter according to the DLMS / COSEM. Here, the DLMS / COSEM is one of the international standards for the remote meter reading system. It is used by the manufacturer, the meter type, the energy to be measured, etc., between the meter and the meter data management system. A communication protocol layer and an object-oriented service communication modeling technique for ensuring interoperability by enabling communication without being restricted by conditions such as type, type, and communication medium.

Also, the client program 1000 displays information on the parameter selected by the user on the upper screen. The upper screen includes OBIS recognition code information, class ID information, and attribute ID information of a parameter. The user can select a watt-hour meter to be measured from the list, and can provide a service for reading, writing and action parameters of the watt-hour meter in real time.

Typically, the watt hour meter stores the Load Profile (LP) information every 15 minutes and has data in it for a few months. In the client program, the data of each of these watt-hour meters can be fetched by using the timer at regular intervals. The data may be stored in a separate database. The user-oriented HMI (Human Machine Interface) uses these databases to utilize and control more various monitoring and analysis information. The client program 1000 can receive an ID and a password from a user to enhance security, and can decode the communication result and provide the measured value and the unit information on a screen so that the user can easily recognize the measured value and the unit information. Detailed information on this will be described later with reference to the drawings.

4 is a diagram showing a structure of a screen provided by the client shown in FIG.

Referring to FIG. 4, according to the HMI providing system for measuring a watt hour meter according to some embodiments of the present invention, the structure of a screen provided by the client program 1000 can be divided into a plurality of categories.

For example, the screen of the client program 1000 can be divided into four categories (for example, login, environment setting, measurement result inquiry, data storage), and each area can be hierarchical.

Specifically, for example, a user ID and a password can be input in the 'login screen', and a port setting, a manufacturer password, a server setting, and a connection setting can be performed in 'environment setting'. In addition, in the 'measurement result inquiry', it is possible to inquire real-time measurement results, display set value change results, inquire operation results, and inquire LP information. In 'data storage', LP data can be stored. However, this is merely one example, and the present invention is not limited thereto.

5 and 6 are views showing screens provided by the client shown in FIG.

Referring to FIG. 5, according to the HMI providing system for measuring a watt-hour meter according to some embodiments of the present invention, the 'login screen' provided by the client program 1000 is as shown in FIG. That is, in the 'login screen', 'user ID' can be selected or input, and a 'password' required for login can be inputted. When the inputted 'user ID' and 'password' are authenticated, the client program 1000 can be switched to the screen shown in FIG. However, the present invention is not limited thereto.
