The present invention relates to an integrated meter-type electricity meter for preventing theft, and more particularly, a usage amount transmitted from them including terminals capable of connecting a communication line for pulse transmission of water, gas, hot water, and a calorimeter to the inside of the electronic electricity meter. It adds a function that integrates the electricity meter to make the function of the electricity meter multifunctional, and eliminates the need for the installation of a separate communication terminal or an integrated metering device, which can greatly reduce the size of the enclosure in which the electricity meter is installed, as well as the installation cost and installation. It can greatly improve the performance, and also detects the challenge and transmits it to the display and the remote place, and prevents unfair power usage due to the challenge, and also reads the meter in the analog equipment meters and the electricity meter due to the disturbance on the line. When data of different meters are different from each other, it is a wireless terminal such as PDA To the to be easily corrected using the invention it will be made to the correct meter reading.

In general houses and various buildings, electricity meters are installed to read the electricity consumed so that an appropriate usage fee can be charged according to the electricity consumption.

These meters can be classified into mechanical (also referred to as "inductive") and electronics, depending on their operation.In the case of electronic meters, the meter is more reliable and stable than mechanical, and can be miniaturized due to the integration of internal circuits. It has the advantage of being possible.

Such a power meter (1), water meter (2), gas meter (3), hot water meter (4) and calorimeter (5) is usually a single communication terminal 6 or an integrated meter reading device as shown in Figs. It is connected to (7) to enable remote meter reading.

In addition, in the case of the communication terminal 6, the power usage data inputted as data from the electricity meter and the usage amounts inputted as pulses from the water, gas, hot water, and calorimeter are simply integrated to transmit the data through the communication line. In order to prevent damage due to external exposure and inflow of moisture when installed in a building, as shown in FIG. 3, the electricity meter 1 is installed and used together in the enclosure 8 installed therein.

However, in the above, since the power meter 1 is in a state in which power is supplied in itself, the power meter 1 continuously calculates the power used therein and displays it on the display, and if necessary, transmits directly to a remote meter through an IR port or transmits a communication line. It is configured to transmit to a communication terminal unit 6 or an integrated meter reading device 7 installed in the home, or to a remote integrated management system.

In addition, in the case of the communication terminal stand 6, a communication line (for example, RS-485 communication line) for delivering the accumulated usage to another communication terminal stand or an integrated management system including several terminals for connecting the above-mentioned meters. In addition to the connection terminal and at the same time including the amount of input from the pulse meter, including a separate power supply for supplying power to the internal microcomputer that continuously calculates the amount of input from the meter It has a backup battery for it.

In addition, the integrated meter reading device (7) is a configuration of the communication terminal 6 is provided with an IR port and a display further configured to enable infrared communication with the wireless remote meter terminal carried by the reader. have.

Therefore, the conventional remote meter reading integrated system must not only supply a separate power supply by forming a separate communication terminal or an integrated meter even though the power meter is supplied to the electronic meter, and separate the communication terminal or the integrated meter from the meter Since it needs to be formed and installed, the installation work is complicated and the production cost is high, which causes unnecessary economic burden on the installer.

In addition, since the communication terminal unit is installed in the enclosure together with the electricity meter, the size of the enclosure in which the electricity meter is installed is not only large, but the production cost of the enclosure is high, and the inner wall of the building in which the enclosure is installed is not beautiful. There is this.

In addition, when the communication terminal block is installed in the enclosure together with the electricity meter as described above, there are problems that a lot of communication errors occur because electromagnetic waves and magnetic fields generated from the inside of the electricity meter or external wires thereof flow through various communication lines connected to the communication terminal block. .

Recently, the Korean Utility Model Registration No. 20-0356997 has been published "integrated electronic electricity meter for remote meter reading", which is the "voltage converter unit and current converter unit, the voltage value and current signal input from them to the power value A power conversion and measurement unit configured to multiply and convert a value proportional thereto into a pulse or digital value, the power conversion and measurement unit for measuring electricity consumption, and an operation unit for calculating a value sent from the power conversion and measurement unit and converting the power amount into power; A display unit for allowing a user or a supplier to check the converted power, a pulse input unit for receiving a pulse from a facility meta-meter, a communication unit for transmitting data to a terminal for each unit, and a facility even when correction occurs Rechargeable battery to be able to detect signal from meta normally Is composed of the charging the battery with a charging circuit capable of always filled with the configuration "integrally built in the body.

In addition, the integrated electronic meter for remote meter reading is configured to transmit data by communicating with the terminal for each unit in a certain time unit to transmit data to the central computer.

However, such a configuration simply receives meter reading data of various equipment meters (water, gas, hot water and calorimeter) as a pulse, calculates the data, and transmits the data to the central computer through the terminal of each unit. There is no function to detect or prevent a challenge.

On the other hand, various equipment such as water, gas, hot water and calorimeters detect the amount of tap water, gas or hot water and heat, etc. as an analog pulse signal and transmit it to the integrated electronic meter for remote meter reading.

Therefore, when interconnecting them with the integrated electronic meter for remote meter reading, the initial value of the equipment meter (the equipment meter is not set to "0") should be set according to the electricity meter. By connecting a computer or a terminal through a line and using a computer or a terminal to directly match or initialize the data of the meter and the electricity meter, the procedure is very complicated.

In addition, data is often lost due to various disturbances flowing on the line while the usage data pulses detected by various equipment meters are transmitted to the electricity meter through the signal line. If it is lost, the actual meter values and the meter reading will be inconsistent.

Therefore, it is necessary to regularly match the data values of the equipment meter and the accumulated values on the hydrometer. In the related art, as described above, a calibration operation is performed by opening a power meter box and connecting a computer or a terminal through a communication line. There is a complicated problem with the calibration process since it must be carried out.

In addition, in recent years as a measure to prevent the challenge has been published in the Korean Utility Model Registration No. 20-0357254 "electronic wattmeter with anti-conduction function", which "rectified the AC power supply to the operating power to each circuit unit It includes a power supply circuit unit for supplying, a current transformer for outputting a signal proportional to the power consumption, and a central processing unit (CPU) for receiving the output signal of the power detection unit to accumulate the amount of usage and control external devices In the electronic wattmeter consisting of a control unit consisting of a plurality of auxiliary devices for assisting the operation of the central processing unit, and a data display unit showing the contents to the user by a signal provided from the control unit, in the neutral line between the power supply side and the general load Anti-conductivity for sensing current connected between 2S terminal on power side and 2L terminal on load side The control unit includes a current limiting function including a current limiter, wherein the CPU of the controller detects whether a signal is generated from the current limiting current transformer, accumulates the amount of power used by the current limiting current current limiting current signal, and accumulates the current amount. Has a built-in reverse detection program.

Therefore, even if a power user uses an unfair power due to a conducting activity, the user can measure and accumulate all the use of the electricity. The cost of losses can be reduced, eliminating the cost of electricity.

However, the electricity meter with such a configuration can only sense the challenge and measure it all, but can not display the fact of the challenge itself or transmit it to a remote system operating computer or a terminal of the same place. There is a problem that you cannot take the necessary action.

The present invention has been made to solve such a conventional problem, including the terminals that can be connected to the communication line for transmitting pulses of water, gas, hot water and calorimeter inside the electronic electricity meter is transmitted from these It adds the function to integrate the usage (ie, adds the function of communication terminal or integrated meter in the electricity meter) to make the function of the electricity meter multifunctional and eliminates the need for separate communication terminal or integrated meter. In addition to significantly improving the performance, the size of the enclosure in which the electricity meter is installed can be significantly reduced.In addition, it can detect and transmit a challenge to a remote location and prevent unreasonable power use due to the challenge. Meters metered on analogue facility meters and electricity meters due to disturbances on the track To the data provided by the anti-theft integrated meter type watt-hour meter which can be made accurate readings by making it easily corrected by using this, a wireless terminal such as a PDA be different from each other when it is an object.

It is characterized in that the installation to remove the surge and noise.

The connection terminal and the communication port are basically installed on the lower side in the main body, but may be provided on any one of the side surfaces.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A display unit 22 for displaying power consumption during normal times and displaying water, gas, hot water, and heat when the user requests it, as well as displaying it during a challenge;

It is characterized by consisting of a light emitting diode 23 used when correcting the error.

In this case, an optical coupler 24 and 25 are installed between the communication line between the operation unit 15 and the control unit 18 and between the connection terminals 16 and the control unit 18, and the power supply unit 1. On the AC power line connected to the input terminal of is characterized in that the surge and noise prevention unit 26 is additionally installed.

In addition, although the connection terminal 16 and the communication port 20 are provided in the lower part side inside the main body 11, you may install in either side part of both side parts.

In addition, the display unit 22 is configured to display five or three kinds according to the needs of the user and the site, such a display change is possible through a wireless terminal, the wireless terminal to present a PDA, etc. do.

Referring to the operation and effect of the invention the anti-theft integrated meter-type electricity meter configured as described above are as follows.

First, in the main body 11 of the integrated anti-theft meter type electricity meter of the present invention, several connection terminals 16 and the communication port 20, which are conventionally installed in the communication terminal block or the integrated meter reading device, are installed. It is only necessary to connect the communication lines connected with other electricity meters installed in the building or the integrated remote metering system, such as the pulse transmission communication lines 27 connected to the hot water and calorimeter.

Therefore, it is easy to install and connect to various meters including electricity meters, and the installation cost is low. In particular, communication terminals and integrated metering devices are not required. It can bring great economic benefits to consumers.

On the other hand, the power supply unit 12 in the integrated anti-theft meter reading type electricity meter of the present invention rectifies the AC voltage input to the DC voltage while the power is normally supplied to each part (operation unit 15, control unit 18 and display unit 22) ), The control unit 18 can continuously integrate the amount of water, gas, hot water, and calories including the power consumption.

At this time, since the surge and noise prevention unit 26 is installed on the AC power line connected to the input terminal of the power supply unit 12, surge and noise that can be input through the AC power line are supplied to the power supply unit 12. Electrically adverse effects can be prevented beforehand.

In addition, since the backup battery 19 is also provided in the electricity meter of the present invention, when the power supply voltage of the power supply unit 12 is cut off due to a sudden power failure as described above, the backup battery 19 is immediately discharged from the backup battery 19. Since power is supplied to the control unit 18, the amount of water, gas, hot water, and calories used, except for electricity that is already out of power and never used, can be continuously integrated.

In addition, the shunt 13 and the current transformer 14 constituting the current sampling unit are respectively installed in the active line 1S-1L and the neutral line 2S-2L between the power supply side and the general load to detect current. Through the use of the normal AC voltage in the subscriber's house and the challenge is made by the user himself or unspecified person, the power consumption by the challenge is also detected and transferred to the operation unit 15.

Therefore, the calculation unit 15 calculates the power consumption based on the current detected through the shunt 13 and detects the conduction based on the current detected through the current transformer 14 (that is, the live current and the inactive line). It is possible to calculate the amount of power used as a challenge by the user or an unspecified person, and transmit the measured current to the control unit 18.

In this case, when the power consumption or the conductive state display data calculated by the calculating unit 15 is transmitted to the control unit 18 through the communication line as it is, an error may occur in the data by electromagnetic waves or magnetic fields generated in the surrounding power line through which high voltage flows. There is concern.

Therefore, in the present invention, the optical coupler 24 and 25 may be installed between the output terminal of the operation unit 15 and the input terminal of the control unit 18 to prevent an error due to disturbance or an error due to power consumption and conduction detection. It was made.

In addition, the optical coupler (24, 25) is provided between the various connection terminals 16 and the input terminal of the control unit 18, which is connected to the various equipment, that is, the pulse transmission line 27 of the meter The external noise was prevented from being transmitted to the control unit 18 in the form of external noise in each usage data inputted by pulses from the water, gas, hot water, and calorimeter.

Accordingly, the power usage data, the conductive use state recognition data, and the water, gas, hot water, and calorie usage pulse signals input to the controller 18 are inputted with accurate usage data and pulse signals from which various external noises are removed.

Meanwhile, the controller 18 continuously accumulates the power consumption input through the calculation unit 15 and at the same time checks whether the conductive state data is input, as well as inputs a pulse through several connection terminals 16. The amount of water, gas, hot water, and calories used is accumulated and output to each part as necessary.

At this time, the controller 18 normally receives the output signal of the calculator 15 and accumulates all the power consumption irrespective of the normal state or the challenge, and continuously displays it on the display unit 22 while conducting the challenge. When it is generated, it is determined by the user or by a third party, and when the challenge is performed by the third party, the display unit 22 displays it (for example, causes it to blink).

That is, the challenge may be intentionally made by the user, or the challenge may be made by a third party. When the challenge is made by the third party, the user immediately recognizes the challenge through the display unit 22. And take the necessary steps.

In the above, an example of operating the display unit 22 by blinking as a method of displaying a conductive state is provided. However, the present invention is not limited thereto, and an alarm device such as a buzzer may be operated instead of driving the display unit 22. .

Meanwhile, as described above, the controller 18 accumulates and grasps the power consumption and the conductive state through the data input through the normal operation calculator 15, displays them on the display 22, and at the same time, several connection terminals. Water, gas, hot water, and calories used as pulses are summed up through the 16 and displayed on the display unit 22 as necessary, or another power meter at a remote place through the communication port 20 or the IR port 21. B is transmitted to an integrated remote system or a wireless terminal carried by the meter reader.

That is, the controller 18 may remotely communicate with another electricity meter or an integrated remote system through an RS-485 communication line connected to the communication port 20, and transmit and receive the accumulated data and the conductive state data, and the IR port. Infrared communication with a wireless meter for a remote meter, such as a PDA carried by the meter reader through the 21, and also in the normal display of the power consumption on the display unit 22, water, gas, It can also display hot water and calories.

Therefore, the operator of the system can check the amount of power and water, gas, hot water and heat used in a specific user's home through the remote meter or the wireless terminal at any time through another electricity meter, an integrated remote system or a wireless terminal. If a challenge is challenged by a third party, it can be immediately recognized and the necessary action can be taken immediately.

In this case, various methods may be proposed as a method of sending the presence / absence detection data or monitoring the conduction in the integrated remote system.

As soon as the challenge is made, the present invention can be delivered immediately to the integrated remote system connected to the communication port 20 via a wire in the meter of the present invention, so that it can be immediately recognized. Alternatively, the SCAN method can be used in the integrated remote system. You can also regularly monitor the challenges of each user.

In addition, in the device of the present invention, each of the facility meters displayed on the display unit 22 of the meter and the display value of the facility meter during the initial or intermediate inspection of the device using a wireless terminal carried by a meter reader or the like, that is, a PDA The cumulative display values for can simply be set to match each other.

That is, when you install the electricity meter which is the device of the present invention in a specific user's premises, and connect the various meter installed in the premises with the electricity meter to perform integrated meter reading, the initial value of the various meter is not set to "0". At the same time, the indication of the facility meter has to be set on the electricity meter, and the pulses transmitted from the facility meters during use are lost due to the disturbance on the line, so that the indication of the actual facility meters and the value displayed on the electricity meter are often inconsistent. In this case, it can be easily set or corrected through a PDA, which is a wireless terminal that can communicate with the IR port 21 without connecting or setting a computer or the like through the communication port 20 as in the related art.

There are several ways to set up and calibrate. For example, first run the setup and calibration program stored in PDA, the wireless terminal, and select the data file containing the address information. When the password is input together, the water, gas, hot water, calorie and household address are displayed on the display unit 22 of the electricity meter. In this state, a desired name is selected using a PDA and the desired number is keyed in to display the equipment meter. The value and the value displayed on the display of the electricity meter can be matched.

In addition, the integrated anti-theft meter-type wattmeter of the present invention is provided with a light emitting diode 23, which is used when correcting errors in the calibration of the wattmeter.

On the other hand, the connection terminal 16 and the communication port 20 is preferably installed on the lower side in the main body 11 as shown in Figure 6 when viewed from the side of the work and moisture inflow prevention, any one of the two side parts, if necessary You may install it in the side part.

In addition, Figures 7a-7b is an exemplary view of the display unit of the present invention, it can be seen that the display unit 22 is configured to display five or three types according to the needs of the user and the site.

Although the above-described embodiment has been described with respect to the most preferred embodiment of the present invention, it is not limited to the above embodiment, it is apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.

As described in detail above, according to the present invention, an integrated electric power metering circuit and an integrated circuit of a communication terminal block or an integrated metering device are incorporated in the electronic power meter, and various connections and communication terminals installed in the communication terminal block or the integrated metering device are included. Is installed inside the electricity meter, so that all meters and communication terminals can be connected to the electricity meter for remote metering and integrated meter reading, so that the number of components due to remote metering and integrated metering is small, greatly reducing the production cost and improving installation cost. The economic burden on the contractor can be greatly reduced.

In addition, the use of a communication terminal block can greatly reduce the size of the electricity meter installation enclosure, thereby reducing the production cost of the enclosure, as well as beautiful interior walls of the building in which the enclosure is installed.

In addition, when a challenge by the user or a third party is made, the amount of power that is challenged can be accumulated, and the fact of the challenge can be displayed and transmitted to a remote location, thereby preventing unjust power usage due to the challenge, Economic losses can also be prevented.

In addition, when the data of the analog meter and the meter read from the meter are different from each other due to the installation of the electricity meter and the meter, or the disturbance on the line, the initial value can be easily set and corrected by using a wireless terminal such as a PDA. It is possible to carry out the operation according to the setting and correction, as well as to more accurately read the use amount of water, gas, hot water and calories, thereby greatly improving the reliability of the meter reading.

In addition, the electromagnetic wave and magnetic field generated inside the electricity meter can be completely blocked from flowing through the communication line, so it is possible to transmit and receive pulse and communication data transmitted from various meters more accurately. It is a very useful invention that can greatly improve the reliability according to the operation.
