Description

Identifing system of telemetering information and exhausting amount of carbon dioxide using wire or wireless telecommunication technology

The present invention relates to a remote meter reading information and carbon dioxide emission check system using a wired or wireless communication technology, and more specifically, to the power consumption and gas usage from the meter modem and analog gas usage meter installed in the analog integration meter The present invention relates to a system that enables the real-time checking of energy-related information used in the home and the amount of carbon dioxide emitted by receiving and outputting the energy information to an indicator.

More specifically, the present invention captures the mark corresponding to the number indexed on the numeric plate of the totalizer, converts it digitally, and reads it to wirelessly determine the total amount of the meter that can read the weighing value more accurately than in the related art. It is about a system to read.

In each home or workplace, power supply is essential for people to maintain a smooth life and activities. Businesses that supply such power to each customer will install electricity meters in each customer to measure the amount of power supplied to each customer, and charge the usage fee according to the measured value. However, when there are a large number of subjects to charge the usage fee, the method of charging the usage fee by checking the electricity meter by the meter reader becomes inefficient. In order to solve these problems, various remote meter reading systems have been proposed.

Such a remote meter reading system has evolved from a remote meter reading system through a wire to a remote meter reading system through a wireless system, and the wireless remote meter reading system is particularly useful for wide area remote meter reading because no communication line is required.

The electricity meter currently used for wireless remote meter reading is an electricity meter that measures the amount of power supplied to and used by an analog user and displays it numerically, and a wireless communication device for transmitting the metered data measured by the electricity meter to a remote center. It is composed by combining.

The development of low-cost, high-performance remote metering technology is one of the big issues in many countries and companies. Currently, the remote meter reading for the electricity meter, which is proposed or implemented in Korea, is mainly attempted a wireless method such as a wired method, a zigbee or an RF communication method using a telephone line or a power line communication method.

However, this remote metering technology is focused on the transmission and reception of meter information between the home and the utility company, which is inconvenient to check the meter directly in order to check the meter installed outdoors. In addition, even if the general consumer checks the meter installed outdoors, it is almost impossible to determine how much power is being consumed by using only the meter reading of the analog-type integrated meter. In other words, it is urgent to develop a system that can check power consumption and billing information, which may be a real consumer concern, in real time.

In addition to power consumption, gas consumption also causes inconvenience in acquiring meter reading information. As the supply of city gas is paid according to the usage amount, a diaphragm type gas meter for measuring gas consumption is installed outside the home or apartment. The diaphragm type gas meter has a pair of membranes (diaphragms) installed therein, and the gas is supplied by the pumping action of the diaphragm. At this time, the amount of gas supplied is measured and displayed using a gear mechanism associated with the diaphragm.

The diaphragm type gas meter is a typical example of a gas meter, which is light in weight and small in volume, and is widely used for home or business use. The diaphragm flows back and forth due to the pressure difference between the surfaces, and the mechanical use is continuously performed by the flow mechanism and the valve so that the actual usage appears on the display.

In the conventional gas meter as described above, the cumulative value of the measurement data should be recorded every unit time, so that a space of the memory for storing the measurement data should be sufficient. Therefore, a large capacity memory must be provided, which causes a cost increase.

In addition, in order to charge a gas fee to the user based on the measurement data recorded in the memory, the meter is directly connected to the gas meter using a separate connector, so that the reader must move to the place where the gas meter is installed and check it. There is a troublesome problem.

Even from the point of view of the user in the home, there is a problem in that the user needs to check the metering information of the gas meter in order to read the gas consumption. However, it is difficult to check the billing information according to the use of the gas using only the metering information.

Hereinafter, the problems of the related art will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an embodiment of a conventional totalizer.

The remote meter communication module is mainly installed in each household in a group house such as an apartment, and is connected to a remote meter reading system such as a central control unit (CCU) and a meter reading server installed at a management office. It is usually used by the management office to remotely read and charge electricity, gas, water, hot water, heating, and cooling by generation.

Such a remote meter reading communication module is connected to the central control unit of the management office and communicates with each other via a wireless communication by radio frequency or a dedicated communication line according to a serial communication method such as an RS-485 method.

In general, meters of electricity, water, gas, etc., as well as the consumer's residence is installed to read the amount of electricity, water, gas, etc. that they supply or use. The meter mainly takes the form of an integrated type meter, that is, an integrated meter, in which the amount used is accumulated or summed to visually display the amount. Among these meters, the integrated power meter as shown in FIG. 1 includes a board 31 on which various information or numbers are printed, a rotating plate 32 that varies in rotation speed according to the amount of use, and rotation of the measuring plate. It is composed of a plurality of numeric plates 33 which display the integrated amount to be measured by numbers such as the ones place, tens place, hundreds place, thousands place, and the like. Of course, the front of the meter may be optionally provided with a transparent cover 34 for checking the number plate. Here, each number plate 33 is displayed in Arabic numerals from 0 to 9 to display the integrated amount in a continuous manner such as a clock. That is, when the number plate of one digit rotates once, the amount of power is displayed in such a manner that the number plate of ten digits is rotated by the unit number. On the other hand, the number plate of one digit is displayed continuously as the rotating plate 32 is rotated, that is, the integrated amount of the one digit number in an analog manner. In addition, such a conventional integrated meter has been metered by a method that the meter reader checks the current number through the naked eye and records it in the state where the accumulated amount continuously changes, and has charged a user corresponding to the metered amount.

However, there are various problems with such an integrated meter and meter reading method. First of all, the meter reader must visit Gagaho to read the meter, so it takes too much metering time and metering manpower, and when the meter is installed in a position where the meter cannot be directly read without the user's guidance, there is a problem in that the correct amount can not be read. . In addition, when the meter reader directly reads, since the number plate of the work must be read with the naked eye continuously, there is a problem in that the amount of use of each household cannot be read at the exact same reference point.

In order to solve this problem, a multi-counter system has been proposed in which a totalizer is configured by a digital method using a pulse value of the totalizer rather than an analog method by rotation of a number plate. However, such a digital remote meter reading system is expensive because its manufacturing cost is low, the economical efficiency is lowered, and the actual pulse value and the numerical value of the totalizer which are output by the analog method are often different from each other, which reduces the reliability of the meter reading. have.

The generation meter 11 provides the amount of usage to the pulse input unit 6 as a pulse signal.

The pulse input unit 6 is composed of, for example, a pulse counter that counts the pulse signal input from the generation meter 11 and converts the result into a digital signal and provides the result to the central processing unit 1.

The central processing unit 1 calculates the generation value by calculating the pulse count value provided by the pulse input unit 6 according to a program stored in a program storage means such as, for example, a ROM (Read Only Memory). That is, the central processing unit 1 may calculate the power usage fee by, for example, converting power consumption according to the pulse count value for a predetermined time, and / or multiplying the converted power consumption by a billing rate. . The central processing unit 1 stores in the metered value storage unit 3 the household-specific metered value consisting of the calculated power consumption and / or power usage fee.

The display unit 2 may be configured of, for example, a liquid crystal display or a display composed of a plurality of seven segments.

The meter storage unit 3 may be composed of, for example, a random access memory (RAM) or a nonvolatile ROM.

Transmission to the remote meter reading system 20.

In more detail, such a remote metering technology focuses on transmitting and receiving metering information between a home and a power company or a gas company, and thus there is a problem in that a consumer cannot easily check power billing information. That is, even if a general consumer checks a meter, it is impossible to determine how much power is currently being consumed using only the meter reading information. Therefore, it is easy to check the power or gas fee that is actually consumed and charged in the home. Development of apparatus and methods is required.

In another embodiment, the modem controller 230 receives the power reading information transmitted from the meter microcomputer 100 in real time, and compares the power reading information with preset reference data to determine the power state for each customer. Judge the abnormality. The preset reference data may be a change in average power usage of the corresponding customer, that is, a change in average power usage by time zone, daily, weekly, monthly, night and day. If an event occurs that satisfies one or more criteria, it is detected and notified to the energy information indicator 300. The abnormality of the power state of the customer may be determined to be an abnormality in the power state of the customer when the difference between the power fluctuation of the customer and the predetermined power fluctuation is more than a predetermined range.

The encoder 240 is used to encode power metering information transmitted from the meter micom 100 to the energy information indicator 300. The power metering information is packetized through the encoding. In another embodiment, the encoder 240 may be formed in the meter micom 100 instead of the meter modem 200 so that a packet encoded with power metering information may be directly input to the meter modem 200.

The power meter reading information encoded through the encoder 240 is transmitted to the energy information indicator 300 through the third communication module 250. The third communication module 250 is connected to the energy information indicator 300 through a wired or wireless communication network, and is connected to the modem controller 230 through a serial port.

The third communication module 250 may be a wired communication module such as a PLC module or a wireless communication module such as a wireless LAN, binary CDMA, or an RF module. To this end, the third communication module 250 may include a wired communication network interface such as a PLC interface or a wireless LAN interface, a binary CDMA interface, an RF interface such as an RF interface.

The power line communication (PLC) method is a method of reading a power line used as a signal transmission line used by a power company to supply electricity to a home, a factory, or an office. Power line communication is a method of communicating data through a power line using a commercial AC signal as a transmission medium. Since a sinusoidal wave of a commercial AC power source and a communication signal (for example, several tens of KHz) are multiplexed and transmitted simultaneously, Communication is available wherever power is available.

Binary CDMA communication modem can be operated in ISM band that does not need additional license from 2.4㎓ to 2.485㎓, and can provide data rate up to 5.625Mbps for use in WPAN. After the packet is constructed, the signal is transmitted through Q-QPSK modulation.

In addition, it is preferable that the RF uses, for example, a ZigBee standard, which can be implemented at low power and low cost.

On the other hand, the RF module can communicate with the field connection device capable of short-range wireless communication by the same communication standard as the RF module. In this case, the modem controller 230 may be configured to perform control according to a request from the field access device after performing the authentication procedure of the field access device when the communication connection request from the field access device. The request from the field connection device may exemplify a request for checking the power meter reading information of the corresponding electricity meter, a request for parameter adjustment of the corresponding electricity meter, and the like.

Alternatively, the power meter reading information can be checked from the outside by receiving the power meter reading information from the meter micom 100 and storing it in an RF tag and reading it through an on-site access device such as an RFID reader.

As a method of authenticating the field access device by the modem control unit 230, the energy information display unit 300 provides identification information (authentication information) that can be connected to the power meter in advance, and requests communication connection from the field access device. The identification information (authentication information) included in the information may be made by comparing the identification information (authentication information) given from the energy information indicator 300. Alternatively, the modem controller 230 may directly identify and authenticate identification information (authentication information) of the field access device included in the communication connection request information from the field access device.

The fourth communication module 310 is connected to the third communication module 250 of the meter modem 200 or the fifth communication module 460 of the gas meter 400 by a wired or wireless communication network and thus the meter micom 100. Measurement data such as power consumption and power usage fee captured by the camera, gas usage and gas usage fee information captured by the gas meter 400, a communication network connection state between each communication module, a data transmission and reception completion state, and a power supply unit It transmits and receives metering information including battery remaining status, meter and gas meter status information, recent meter reading history of meter and gas meter, power line status information, and the like.

Preferably, the fourth communication module 310 transmits the power meter reading information request signal to the third communication module 250 of the meter modem 200, and the third communication module 250 responds thereto. The power meter reading information is transmitted to the fourth communication module 310.

In addition, the fourth communication module 310 transmits a gas measurement information request signal to the fifth communication module 460 of the gas meter 400, and the fifth communication module 460 measures gas in response thereto. The information is transmitted to the fourth communication module 310.

The power meter reading information and the gas metering information received through the fourth communication module 310 are decoded through the decoder 320.

Meanwhile, according to an embodiment different from the embodiment shown in FIG. 3, the information received from the third communication module 310 or the fifth communication module 460 may be captured by the imaging unit 102 or the gas meter of the meter micom 100. The image information may be image information of the data captured by the image capturing unit 430. That is, the meter micom 100 and the gas meter 400 provide only image information related to power or gas usage, and receive it from the energy information indicator 300 to read an image to read digital data of power usage or gas usage. Based on this, the billing degree such as the electricity usage fee, gas usage fee and the like can be calculated.

According to this embodiment, not only can the image reading module or the usage fee calculation module be removed from the meter micom 100 and the gas meter 400, but also the memory capacity can be drastically reduced, thereby minimizing the volume of the meter. Can reduce the production cost. In addition, since the data communicating between the meter, the gas meter 400 and the energy information indicator 300 is only image data captured, it is possible to reduce the load associated with the communication amount and simplify the communication line.

In another embodiment, the captured image data may be read by the A / D converters 103 and 440 of each meter, converted into digital information, and transmitted to the energy information indicator 300. In this case, the amount of data transmission and reception between the meter and the energy information indicator 300 may be further reduced.

Meanwhile, the usage information transmitted from the meter to the energy information indicator 300 may be transmitted at regular time intervals rather than in real time. For example, when it is not necessary to confirm accurate power usage and charging information every time, the energy information indicator 300 receives the usage and usage fee information from the meter every 15 minutes and stores it in the display memory 330. May output the most recently received information according to the user's command. In this case, compared to the case of transmitting data in real time, data traffic can be reduced.

The indicator memory 330 may include a read only memory (ROM) and a random access memory (RAM), and the power reading information and gas metering information transmitted from the fourth communication module 310 to the indicator memory 330. The time zone, daily, weekly, monthly, night, date, etc. can be classified and stored in real time.

The indicator controller 340 controls each unit of the energy information indicator 300. The display controller 340 controls the fourth communication module 310 according to a request signal of power meter reading information or gas metering information input from the key input unit 360 to control the third communication module 250 or the fifth. When the request signal is transmitted to the communication module 460 and the gas metering information is received from the third communication module 250 or the power metering information from the fifth communication module 460, the signal is output to the output unit 350. .

In addition, the display controller 340 may execute an application program loaded in the display memory 330, control input / output of data, and control the decoder 320 to decode the data. In addition, the fourth communication module 310 may be controlled to control transmission and reception of power meter reading information or gas metering information between the meter modem 200 and the gas meter 400. In addition, a process of outputting the received power meter reading information or gas metering information through the output unit 350 may be controlled, and the corresponding module may be executed by analyzing an input signal input through the key input unit 360.

According to another exemplary embodiment described above, the indicator controller 340 may receive only image data photographed from the meter and read the calculated image data to calculate power or gas usage, and calculate the power or gas usage fee based on this.

The output unit 350 outputs meter reading data according to a control signal from the indicator controller 340. The meter reading data may be hourly, daily, weekly, monthly, nightly, date, power consumption, power consumption rate calculated by multiplying the metered power consumption by the base rate, and the gas meter 400 Measured gas metering information can be output through). In addition, all data that can identify power quality of each customer such as communication network connection status between communication modules, data transmission / reception completion status, power supply battery level status, meter status information, recent meter reading history, power line status information, etc. May be included. Furthermore, the carbon dioxide emission calculated through the carbon dioxide emission measurement unit 370 may be output.

The output unit 350 may be configured as a display device such as a liquid crystal display (LCD), an electroluminescence display (ELD), and the like. The meter reading information may be represented by numbers, letters, symbols, and graphs. As the display method, both digital and / or analog can be applied so that a user can easily recognize it.

The key input unit 360 includes various menu buttons, setting buttons, up, down, left, right movement buttons, reset buttons, and the like, and receives a command from a user. The power meter reading information or gas metering information may be requested through the menu button, and the carbon dioxide emission information calculated by using the power consumption or gas metering information may be requested. In addition, the identification information (authentication information) of the field connection device may be input or changed, or the power reference fee stored in the meter microcomputer 100 may be changed.

The carbon dioxide emission measuring unit 470 measures the carbon dioxide emission by using the power consumption measured through the meter micom 100 and the gas consumption measured through the gas meter 400.

The method of measuring carbon dioxide emissions is shown in Equation 1 below.

CO2 emissions = (power consumption * first coefficient) + (gas consumption * second coefficient)

The first coefficient and the second coefficient may be calculated using a carbon emission coefficient calculated statistically. The carbon emission coefficient is a secondary coefficient for the petroleum conversion coefficient based on the calorific value of crude oil based on the calorific value of 1 kg of crude oil.

For example, burning 1 kg of crude oil produces a calorific value of 10,000 kcal, and burning 1 kg of propane gas produces a calorific value of 12,000 kcal, resulting in a petroleum conversion factor of 1.2 kg (crude oil) / kg (propane). And the carbon emission factor for this is 0.713 ton C / tOE (or 0.713 kg C / kgOE), so if you burn 1 kg of propane gas,

1 kg (Propane gas) × 1.2 kg / kg (oil conversion factor) × 0.713 kg C / kgOE = 0.8556 kg C

Therefore, burning 1 kg of propane gas generates about 855 g of C (carbon). In addition, the relationship between carbon and carbon dioxide is a relationship between C and CO _{2, and} the relationship between 12g and 44g is established in terms of molecular weight. In conclusion, burning 1 kg of propane produces 3.135 kg of carbon dioxide. In this way, the petroleum conversion factor and carbon emission factor for each fuel can be used.

Table 1 is a table illustrating the carbon emission coefficient for each energy.

Referring to Table 1, the carbon emission coefficient of the electrical energy measured through the meter microcomputer 100 is 0.12 kgC / kwh, the carbon emission coefficient of the city gas measured through the gas meter 400 is 0.64 kgC / m ³ to be.

When converted into carbon dioxide emission coefficient (44/12), the carbon emission coefficient of the electric energy is 0.44 kgCO ₂ / kwh, and the carbon emission coefficient of the city gas measured through the gas meter 400 is 2.347 kgC / m ³ . .

The carbon emission coefficient may be changed in time or place, and thus the statistical value may be changed. Therefore, the carbon emission coefficient may be changed and applied in the carbon dioxide emission measuring unit 370. For example, in the case of electrical energy, the declared carbon emission factor is calculated differently according to the composition of power generation fuel in each country.

The carbon emission coefficient may be stored in a memory formed in the carbon dioxide emission measuring unit 370, and may be read and used when calculating carbon dioxide emission.

In another embodiment, the indoor temperature is sensed using an indoor temperature sensor (not shown) formed in the carbon dioxide emission measuring unit 370, and the energy usage is estimated and predicted under the assumption that the indoor temperature is proportional to the energy usage. CO2 emissions can be measured by applying a carbon emission factor to the energy consumption.
