Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a system for providing a combined use error correcting remote meter reading and a security service,

The present invention relates to a technique capable of performing remote automatic meter reading, which also serves to correct a usage error of a city gas, by using one system, and to provide a security / safety related service for a user area.

(1) Necessity of improvement of life information acquisition system

Hyundai is a world where many living information is converted into digital information, and it is natural that the converted information is provided to the people who need it by moving the long distance without limitation through the internet network without restriction. However, this is mainly applied to the part related to intellectual activities, and information closely related to everyday life, for example, information on the use of electricity, water, and city gas is not so. For example, information on the use of electricity, water, and city gas is still input into the charging system by a person manually confirming the meter and manually passing it through. The information once input into the charging system is treated as one of the general intellectual information, processed into various forms, and provided to the person who needs it through the Internet network. In other words, the information delivery system centering on the modern Internet network has a deformed structure in which the generation part of living information still remains in the primitive state, and only the application and use part is extremely developed.

Recently, in the case of electric power, the so-called "Smart Grid" has been proposed and developed and introduced in various countries around the world. However, since the process (communication method, communication standard, etc.) in which the information generated from the watt-hour meter is not unified, various methods are used depending on the manufacturer, and unnecessary element devices are involved in the process. Due to these reasons, the smart grid for electric power is used as a remote meter reading system limited to a certain region unlike the original plan, and is mainly applied to a large-capacity business / industrial user.

In the case of the capital, in a more serious situation, there is virtually no way for the weighing information to automatically enter the universal network. In the case of city gas, technologies using wireless communication such as MOD-BUS, wired communication, ZIG_BEE, and CDMA have been developed, but they are also used for extremely short distance information transfer due to unstable communication.

(2) The necessity of volume correction and calorific correction for city gas consumption

There have also been many attempts for city gas, and several types of products are on the market. However, there are two problems in generating information about city gas. That is, (i) a problem of correcting the volume expansion due to the fluctuation of the temperature pressure, (ii) a problem of correcting the fluctuation of the heat quantity of the raw natural gas, and the like should be solved at the same time. However, technologies and products that solve these problems are not yet developed. Only a piece of technology related to the volumetric compensator or the remote meter using the MOD-BUS or Zig-Bee communication has been developed, and the volume of usage measured by the user's meter or the volumetric corrector is used for volume correction and calorimetric correction , A technique of converting or correcting 'real time' to the most practical unit 'use calorie', or a technique of transmitting it using a general internet network has not yet been developed or proposed. It is necessary to secure city gas usage information more accurately and effectively.

(a) Calculation of volume of city gas: Since city gas is gas, unlike coal and petroleum, volume varies greatly depending on temperature, pressure and composition. For this reason, in order to accurately measure the amount of city gas used, it is necessary to measure the volume of the city gas to be weighed while simultaneously measuring the temperature, pressure, etc. and determine the volume at the reference temperature (0 ^° C) In other words, it is necessary to convert it into 'reference volume'. This conversion is called 'correction of the volume of city gas'. In the case of Korea, since 2008, all city gas is charged to the volume based on the reference temperature / reference pressure calculated by measuring the temperature and pressure when the user desires. For this purpose, the reference gas temperature / A device for converting the volume to a volume at a reference pressure, i.e., a " volume corrector " has been developed and popularized.

(b) Caloric Calculation of City Gas: City gas is a gasification of natural fossil fuel LNG (Liquefied Natural Gas) taken from nature, and LNG is the difference between the composition of natural gas (main component is methane) Therefore, the unit calorific value is different even though it is a city gas having the same reference volume. In Korea, to prevent fluctuation of gas quality and price dispute due to such fluctuation of heat quantity, the government prescribed minimum calorific value so that the supplier could observe this. In order to meet these minimum calorie standards, suppliers meet the criteria by mixing LPG (Liquefied Petroleum Gas), which has a high calorific value, with low calorific LNG. However, due to the continuous demand from the city gas industry for the artificial adjustment of calories, there is a side effect of increasing social costs. In July 2012, Korea introduced a method of converting the amount of city gas to calorie, It is called calorie correction. In order for such a calorimetric system to be introduced, the use time and the meter reading time must coincide with each other. As the system is implemented without sufficient preparation, many side effects are predicted.

(3) Necessity of universalization of the system for obtaining safety information

On the other hand, information that is generated by a general household (or a small branch office) and needs to be used at a remote location includes not only living information related to the use of power / water / city gas, but also a lot of information related to safety and security of life. For example, gas leakage, overheating of cookware, opening / closing of door, unauthorized visitors such as courier delivery, unhealthy access of minors, health problems or safety accidents of single elderly persons, accidents through doors or windows, etc. A lot of information (hereinafter referred to as "daily safety information") is generated at home every day, and many living people want to obtain such daily safety information from a remote place through a normal Internet network.

However, the security system that is currently being developed and distributed is a system that transmits certain information, such as infiltration using infrared rays or a touch sensor, to a specific location such as a security supplier's office through a closed circuit. In addition to the limited use and the disadvantages of the closure, the installation and use price is high, so it is not used in most households. Furthermore, there is an example in which a handheld terminal is presented for the purpose of protecting children from crimes against children, which are increasing in recent years. However, the child-protecting portable terminal uses a conventional telephone system and is large in size and expensive, so it is difficult to actually supply it.

As an alternative to this, some people who necessarily need security information may install an Internet CCTV such as a web camera in a home. However, there is a drawback in that meaningful information can not be extracted unless the information occupied by a large amount of image information generated due to the characteristic of visual information is occupied by extremely low and the transmitted information is not continuously observed. Also, since the amount of information to be generated, processed, and transmitted is large, the cost is also considerable, and thus it is not so widely distributed.

As such, there is a conventional method of generating and delivering the necessary daily life safety information related to security / safety at the home / branch office by installing a web camera, installing facilities of a private security company and a dedicated communication network, Because of the use of telephone service, its efficiency is extremely low. Also, there is not yet a technology that automatically generates various concentrated information in real time and transmits it to a necessary place in real time through a general internet network. In addition, portable apparatuses for protecting children are being introduced only with expensive apparatuses using existing telephone systems.

(4) Necessity of improvement of notification / notification information generation and delivery method

In addition, there are many means of distribution of living information such as the Internet and SNS, but all of them are information generated against an unspecified number of people. It is unexpectedly limited in the means of distributing the public information to be informed to residents of the same apartment complex or to a specific user such as the residents of the same municipality. A public speaker, an interphone, or the like.

In addition, although we often need to contact with opponents who do not know the information we need in our lives and to acquire the information to be notified from them, most SNSs are limited only by mutual recognition through advance registration procedures There is no means for recognizing the delivery of courier or emergency mail at the time of delivery. Therefore, when a visitor attaches a memo to a door or sends an individual notification to the interphone through the security guard, or if the recipient knows the mobile number of the recipient, he or she notifies the user by leaving a character or making a call.

In this way, remote automatic meter reading system, security system, and notification / notification system have been constructed and operated as independent systems without any connection with each other, and there has been a lot of inefficiency in system construction and operation, I did not.

2. Configuration of the system

FIG. 1 shows an overall configuration of a city gas remote meter reading and security service integration providing system 100 according to the present invention. The system 100 includes a volume correction unit 300, an information communication unit 400, a security / notification information unit 500, and a comprehensive information processing unit 700. The service area is divided into several unit areas. There are a number of city gas users (home / branch) in each unit area. A comprehensive information processing unit 700 for each unit area is installed at a predetermined position (preferably at the approximate center of the unit area). The volume correction unit 300, the information communication unit 400, and the security / notification information unit 500 are installed in the user area within the unit area. The information communication unit 400 of the user area is communicably connected to the integrated information processing unit 700. [ The integrated information processing unit 700 of each unit area includes a computer system 810 of an agency (apartment management office, resident autonomy center, 119 and 112), a terminal 820 of a user, A city gas company computer system 830, and the like. These systems can be built by specific administrative or national units.

The city gas meter has a mechanical meter that displays the volume of city gas in a numeric display and an electronic (digital) meter that measures the volume usage and outputs it as a digital value. In the case of the user A, the mechanical meter 200 is equipped with an automatic meter-reader (AMR) 210 for automatically reading the gas metering value and converting it into a digital value to provide an output value of the automatic reader 210 And in the case of an electronic (digital) meter 200, such as a user B, the metering value of the meter 200 may be used immediately.

The volume correction unit 300 includes an input unit 310 for collecting the volume of city gas used from the AMR 210 or the electronic digital meter 200 and a controller 310 for controlling the temperature and pressure of the city gas passing through the meter 200, And an operation storage unit 340 that corrects an error with respect to the usage amount of the city gas by using the information of the gas temperature meter 320, the gas pressure meter 330, and the gas temperature and the gas pressure. Here, the error with respect to the volume usage is an error caused by a deviation of any one of the actual temperature and pressure of the city gas with respect to either the reference temperature or the reference pressure. Of course, when the temperature and pressure of the gas are supplied from the outside, it is not necessary to provide the gas temperature meter 320 and the gas pressure meter 330. The gas pressure measuring instrument 330 is not necessary in the case of performing the volume correction by the temperature correction method, so it is not installed. The operation storage unit 340 may be implemented using an apparatus having a calculation function and a data storage function such as a microprocessor, a microcomputer, and the like.

As a method of correcting the volume error of the amount of city gas used in the operation storage unit 340, any one of the following three rules defined in Korean KS B 8300 and European IEC standard can be applied: (i ) The temperature is measured in real time, the pressure and compression factor are treated as constants (average value, etc.) and the correction volume is calculated (temperature correction method), (ii) the temperature and pressure are measured in real time, (Temperature value correction method), (iii) the temperature and the pressure are measured in real time, and the compression factor is measured in accordance with a predetermined method such as temperature, pressure, (Temperature / pressure compression factor correction method) that calculates the correction volume in real time from the composition or combustion heat amount in real time. Here, it is preferable to use a compression factor for error correction according to the pressure difference. The change in gas volume with temperature and pressure is known to be proportional to the absolute temperature and inversely proportional to the pressure, such as Boyle-Charles's law. However, such a gas is applied to an ideal gas (virtual gas), and an actual gas causes an error depending on the temperature, the pressure, and the composition (kind of gas and mixing ratio). The constant introduced to compensate for this error is the compression factor. This compression factor varies with temperature, pressure and composition. The method of calculating this value is very well known, and KS and IEC have specified the calculation method.

For example, the error correction according to the temperature pressure correction method is performed as follows. The calculation storage unit 340 receives the weighing volume usage [m ³ / unit time] per unit time from the meter 200 and receives the measured volume usage [m ³ / unit time] from the gas temperature measurement unit 320 and the gas pressure measurement unit 330 Temperature and pressure information. The operation storage unit 340 corrects the volume error by applying a deviation of the actual temperature and pressure of the city gas to the reference temperature and the reference pressure at the usage volume [m ³ / unit time]. One method for this is to calculate a temperature and pressure correction factor that can offset the volume error caused by the difference between the reference temperature and the reference pressure and the actual temperature and pressure of the city gas. Then, by applying the calculated temperature and pressure correction coefficient to the measurement volume usage [m ³ ], the volume usage amount corrected to the reference condition (reference temperature and reference pressure), that is, the volume correction usage amount [Nm ³ / unit time] is calculated. If the gas temperature meter 320 and the gas pressure meter 330 are not installed, the temperature pressure correction coefficient can be calculated by statistically applying the average temperature and the average pressure in the corresponding region. Can be minimized. Computation storage unit 340, will be the temperature and pressure compensation coefficient of the region [Nm ³ / m ^3] by a general information processing unit 700 and the information communication section 400 may be provided over the Internet and / or wireless communications.

The pressure value data used for pressure error correction should use the pressure value of city gas, but atmospheric pressure may be utilized. This is because the gas pressure used in the volume corrector 300 is the absolute pressure plus the atmospheric pressure plus the gas gauge pressure and the gas gauge pressure is held constant by the regulator disposed in the piping of the city gas, The variation of the atmospheric pressure has a greater influence on the absolute pressure of the gas. Here, the gauge pressure refers to a pressure value measured by a gauge based on a normal atmospheric pressure, and the absolute pressure refers to a pressure measured based on a vacuum.

The calculation storage unit 340 calculates the correction volume usage by applying the above-described volume error correction method, and the correction volume usage is performed per unit time. The calculated correction volume usage amount is provided to the comprehensive information processing unit 700 through the information communication unit 400 whenever the calculation is performed or a value obtained by accumulating the correction volume usage amount during each charging period is supplied to the comprehensive information processing unit 700 ).

The volume correction unit 300 may be integrated with the information communication unit 400, which will be described later, or may be detachable.

The comprehensive information processing unit 700 receives notification / notification information to be provided to the user from an interested party (e.g., an apartment management office, a resident autonomy center, a 119 system, a 112 system, etc.) through the information communication unit 400 To the security / notification information unit 500 and to provide the user with the output via the output device 550. [

The calorific value correction unit 600 does not exist as hardware but can exist as software in the integrated information processing unit 700. [ It is advantageous to minimize the size of the device according to the invention. The calorific value correction unit 600 has a function of collecting the calorific value information of the city gas provided by the city gas suppliers 830 and 840, a function of collecting the supply delay time of the city gas provided by the city gas supplier, And a function of calculating a calorie correction amount by calculating the real time volume correction usage amount generated by the volume correction unit 300 (see above processing data).

3. How to integrate remote meter reading and security services

FIG. 3 is a flowchart illustrating a process in which a city gas remote meter reading and security service are integrally provided in the system 100.

First, in the city gas meter 200, the volume of the city gas is measured in real time. The AMR 210 automatically reads the meter reading value displayed on the meter 200 at each unit time and converts the read meter reading value into a digital value so that the volume volume usage [m ³ / unit time] is provided to the input unit 310 of the volume correction unit 300 in real time do. The same is true of the digital meter 200 (step S10).

The real-time measurement volume usage [m ³ / unit time] is provided to the operation storage unit 340 and performs an operation for correcting the volume error according to the above-described volume correction method. For example, considering the case of correction by the temperature / pressure correction method, the change of the volume of the city gas due to the temperature and the pressure should be corrected. For this purpose, the gas temperature measuring instrument 320 and the gas pressure measuring instrument 330 measure the real time temperature [ ^o C] and the pressure [kPa] of the city gas passing through the meter 200 every unit time. If there is no gas pressure gauge 330, a fixed value may be used according to KS regulations (steps S12 and S14).

Data of the metering volume [m ³ / unit time], temperature [ ^o C] and pressure [kPa] of the city gas are provided to the operation storage unit 340 of the volume correction unit 300. Also, information on the unit time for performing the volume correction is provided from the outside. The operation storage unit 340 calculates the volume correction data of the real-time city gas usage amount every unit time. Specifically, the information of the temperature [ ^o C] and the gas pressure [kPa] of the city gas at the corresponding time is thermodynamically applied to the metering volume usage [m ³ / unit time] collected in real time from the city gas meter 200 , And the volume correction amount per unit time [Nm ³ / unit time] is calculated by correcting it to the reference temperature volume. The calculation formula for this is described in detail in KS B 8300, and a description thereof will be omitted here. The operation storage unit 340 stores the calculated volume correction usage amount per unit time (step S16).

In advance to provide information relating to the charging period to the operation storage unit 340, a per unit volume of the correction amount calculated during the charging period in the operation storage unit 340 [Nm ³ / unit time] by accumulating the charging period Nm ³ / charge period] (step S 18). Then, the calculated volume usage [Nm ³ / charge period] for the charged charge period can be provided to the comprehensive information processor 700 once at a designated time within the charged charge period. However, unlike this method, the operation storage unit 340 provides the volume correction usage amount [Nm ³ / unit time] per unit time to the comprehensive information processing unit 700 in real time, and calculates the volume correction usage amount The cumulative information processing unit 700 may perform the accumulation. The calorific value correction processing to be described later may be performed every unit time by the operation storage unit 340 of the volume correction unit 300 or may be performed in the comprehensive information processing unit 700 as in the method described later.

In each city gas user area, it is possible to automatically obtain the gas consumption amount corrected for the change of the city gas volume by the temperature and the pressure through the charging process at every charging period (of course, the pressure factor is excluded and the volume correction You can also choose a method). The data thus calculated is provided to the information and communication unit 400 at a predetermined time (step S24).

The security event occurrence information for the user area is detected in real time by the various sensory sensors 510 whenever the event is generated and provided to the data input unit 412 of the information communication unit 400 in step S20. For example, when the optical sensor or the infrared sensor installed at a predetermined position of the user area is used, the light amount of the user area or the change information of infrared rays (whether or not the light is blocked), the intensity information of light or infrared rays can be detected, Whether or not it is intruded by an outsider. A touch sensor or a proximity sensor provided at a predetermined position of the user area is used to detect an event that a person or an object touches or approaches and outputs contact / proximity occurrence information. This information can be used to determine whether an intruder is present or whether there is movement of a person or animal within the user's area. Detects the event that the temperature of the living environment greatly changes from the detection value of the thermal sensor (temperature sensor) to the set value or more, and outputs the temperature change information. This can be used to determine whether a fire has occurred or not. By installing a sound sensor (microphone or the like) in the user area, it is possible to detect a change in the size of the noise in the living environment and to sense the detected sound in an emergency situation using the sound analysis logic. Using the noise generation and size information, it is possible to determine whether a user or an animal is active in a user area, whether an intruder is invaded by an outside person, whether or not the user requests assistance. In addition, a concentration sensor is installed in a user area to detect an event that the concentration of a specific substance (for example, a harmful gas or toxic gas) in the living environment is increased, and a concentration sensor attached to the living information unit . It is possible to determine whether the gas is leaking or the like through the detected concentration change information. An odor sensor for detecting the odor contained in the city gas may be used.

The user who visited the user area can input detection information to be notified to the user by using the input device 530 installed outside the user in step S21 in step S21.

Each sensory sensor 510 transmits the detected security event occurrence information to the data input unit 412 in real time. Also, when the notification information is input, the input device 530 also provides the notification information to the data input unit 412 in real time (step S22).

The operation processing unit 414 collects the security event occurrence information and the notification information provided to the data input unit 412 and wirelessly transmits them to the wireless AP 420 in real time (S24).

The general information processing unit 700 receives information transmitted through the optical LAN, for example, and performs decoding processing. Accordingly, various pieces of information related to the occurrence of security events generated in the user area are collected in real time in the comprehensive information processing unit 700. [ In addition, the real-time corrected volume usage information according to the user's use of city gas is periodically collected in the comprehensive information processing unit 700 at every unit time or every charge period. The integrated information processing unit 700 decodes the collected information and stores the decoded information in a database (step S26).

And further calorie correction may be performed on the collected city gas correction volume usage. In order to calorie calorimetry, information of the unit calorific value of the real-time city gas and information on the delay time of the city gas are required. The unit calorific value information of the real-time city gas is the amount of heat generated when the city gas of the reference volume is burnt, and the unit calorific value [MJ / Nm ³ ] of the city gas being supplied to the region where the meter is installed, Lt; / RTI > The supply delay time information of the city gas is the time (hr or day, etc.) required for the city gas to move along the pipe from the city gas company to the area where the meter is installed, and this information is also collected via the internet and / . The integrated information processing unit 700 obtains the two pieces of information through the Internet or wireless communication means (step S28).

Then, the comprehensive information processing unit 700 calculates the real-time calorie correction usage amount using the obtained two pieces of information. The actual calorific value of the real time gas is calculated by using the information on the correction amount of the city gas volume that is collected in real time [Nm ³ / unit time], the real time city gas unit calorific value [MJ / Nm ³ ] (Hour, hour, day, hour, day, or the like) of the city gas calorie correction amount [MJ / unit time] generated in real time in step S30.

Real-time city gas calorific correction usage {MJ / unit time} _(T) =

Real time city gas volume correction amount [Nm ³ / unit time] _(T) x real city gas unit calorific value [MJ / Nm ³ ] _(Td)

...... (One)

In the above equation (1), the subscript ' _(T) ' denotes a moment. That is, 'X _(T) ' refers to the value of information X at an instant. The subscript ' _(Td) ' refers to the previous point in time as 'unit time' d. Here, d represents the supply delay time (expressed in unit time) of the city gas.

Here, it is described that the general information processing unit 700 performs the calculation of the amount of city gas calorific value correction, but this is merely an example, and it goes without saying that it may be performed in each user area as described above.

The city gas calorific value correction amount calculated in this way is stored in a database managed by the comprehensive information processing unit 700.

Information collected and stored in the comprehensive information processing unit 700 is provided to a specific point (system or apparatus) at a specific time according to a predetermined schedule, or provided in response to a request from an authenticated person. For example, the general information processing unit 700 transmits information on the amount of city gas usage to the computerized systems 830 and 840 of the city gas company for each user for each charging period. Security event occurrence information shall be communicated to the emergency management system of the apartment management office, the emergency communication system of the municipality (resident center), the 119 system and the 112 system selectively or commonly according to predetermined rules according to the type of the information. When the user requests desired information through the Internet using his or her mobile phone or a computer, the information is provided in response to the request (step S32).

In the comprehensive information processing unit 700 or the city gas company computer system 830, the following data can be calculated. The real-time gas usage fee can be calculated by applying the information on the amount of city gas calorific correction used [MJ / unit time] generated in real time and the real-time city gas price [KRW / MJ] This is the amount of city gas used in real time [KRW / unit time].

Real time city gas usage rate [W / unit time] _(T) = Real time city gas calorific correction usage {MJ / unit time} _(T) x Real time city gas unit price [Yuan / MJ] _(T) ....... .(2)

In addition, the usage amount of the fee charging period can be calculated. This data is the sum of the usage period of the city gas supplier during the unit period (for example, 1 month) periodically charged, the 'charge time period weight volume usage [m ³ ]', 'charge period duration volume correction amount [Nm ³ ], 'Calorie Calorie Calorimetry [MJ]', and 'Charge Period Use Charge [KRW]. Also, the total cumulative amount of usage information for each user area of the city gas such as' cumulative volume usage [m ³ ] ',' cumulative volume correction use amount [Nm ³ ] ',' cumulative calorie correction usage amount [MJ] And 'cumulative usage data' related to circulation.

On the other hand, when the system 100 of the present invention is used, the apartment management office or the resident center can inform or notify the entire resident or a specific resident. In the computer system 800 of the apartment management office or the resident center, the manager specifies the delivery destination, the announcement or the notification item and instructs the transmission. In accordance with the instructions, the computer system 800 codes the information to be transmitted in a predetermined format and transmits the information to the corresponding integrated information processing unit 600. The integrated information processing unit 600 receives the notification / notification information signal transmitted from the computer system 800 and transmits the notification signal to the output device 550 of the security / notification information unit 500 through the information communication unit 400 of the user, . Accordingly, the notification / notification information is output from the output device 550 of the corresponding user. The information or publicity information provided by the apartment management office / resident center / self-governing organization in the specific area is transmitted to the security / public information unit 500 in the reverse direction through the comprehensive information processing unit 700 and the information communication unit 400, And is transmitted to the corresponding user through the output device 550 of the notification information unit 500.

In the above description, remote automatic meter reading and correction of the amount of usage of city gas have been described as an example, but the system of the present invention can also be applied to remote automatic meter reading of power / water / hot water heat utilization information. After the amount of usage of the meter is read by the automatic reader (AMR) and converted into a digital value, the usage information is transmitted to the comprehensive information processing unit 700 through the information communication unit 400, similar to the case of the city gas usage amount You can do it.
