Abstract
Description
The present invention relates to a remote automatic meter reading service and a service related to security in a living environment for a user such as a home, an office or a factory using living utilities such as city gas, electricity, and water, And more particularly, to a method and system for providing a composite signal using a conventional method and a mobile communication or an Internet communication method.
(1) Necessity of improvement of the system for acquiring life security information
Hyundai is a world in which diverse information about daily life and activities is converted into digital information, and converted digital information is provided to people who need it without any limitation through internet. However, these are mainly applied to areas related to intellectual activities. Information on the use of life utilities such as electricity, water, and city gas (hereinafter referred to as "life utilities"), which are closely related to people's daily lives and economic activities in homes, offices, A person manually confirms through a meter, manually inputs it into a charge system, and is transmitted to a necessary subject.
However, the system for acquiring and using such utility information needs to be more efficient. In the case of electric power, the so-called "Smart Grid" has been proposed and is being developed and tested 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 electromagnetic communication such as wired communication such as MOD-BUS, ZIG_BEE, and CDMA have been developed, but they are also used for extremely short distance information transfer due to unstable communication.
In addition, the conventional remote automatic meter reading system which is used is installed in each customer, so that when the meter reading terminal that acquires the automatic meter reading value of the utility utility for the first time transmits the meter reading value information from the remote meter reading terminal to a nearby local repeater, Wi-Fi or Bluetooth). However, the electromagnetic wave communication method in the remote automatic meter reading has the following problems.
(i) power consumption is large. In electromagnetic communication, in most cases, either of them must be in the receiving standby state, and the consumed current is particularly large. When sending and receiving the meter reading information by electromagnetic wave communication, the consumed power consumes at least 100 mW, and the standby current for reception requires several tens of mW. This is an important issue when using the battery as a power source.
(ii) The price of communication equipment is high. Devices required for ZigBee, Wi-Fi, and Bluetooth using electromagnetic wave communication include a large-capacity CPU, an electromagnetic wave transmitting / receiving circuit, and the like. These devices are expensive and cost a minimum of USD5 ~ 40 for the communication part only to implement one remote meter reading terminal. The cost burden is not small.
(iii) Installation work is complicated and difficult. In most cases, the electromagnetic wave communication method requires association by hand shaking. The configuration to satisfy the communication protocol (Wi-Fi, Bluetooth, etc.) to be followed in this process is complicated. In particular, initial setting such as sharing information about various components necessary for communication, device identification, communication speed, etc. is complicated.
In order to avoid the problem of the electromagnetic wave communication method, it may be considered to connect the wired communication method from the remote meter terminal to the relay. However, if the remote meter reading terminal and the repeater are connected by wire communication, the above problems will be eliminated, but the installation of the communication line is troublesome and the installation cost due to the wiring work is increased. It is not a practical and practical alternative.
(2) The necessity of volume correction and calorific correction for city gas consumption
Compared to electric power and water, city gas has a large metering error and it is necessary to correct the meter reading value of the meter. Many attempts have been made to correct the meter reading of city gas, and several types of products are on the market. However, there are two problems in generating metering 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 has been devised for a bulb compensator or for a remote meter using MOD-BUS or Zig-Bee communication. A technique for converting or calibrating the usage quantities measured by a user's meter or a volume corrector to "real-time" with the most practical unit of "calorie consumption" by applying a volume correction and a calorimetric correction method, The technology to transmit is not yet 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, an apparatus for converting the volume of a city gas meter to a volume at a reference temperature / reference pressure, that is, a volume corrector, has been developed and popularized.
(b) Correction of city gas calorific value: City gas is a gasification of LNG (Liquefied Natural Gas), a natural fossil fuel collected from nature. LNG has a different calorific value, even though it is the city gas of the same standard volume, because the composition of the extracted natural gas (main component: methane) varies depending on the country of origin. 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 of the city gas industry that artificially adjusting the calories is a side effect that increases the social cost, Korea introduced a method of converting the amount of city gas consumption to calories from July 2012. This is called calorie correction of city gas. In order to introduce such a calorie, the use time and the meter reading time must coincide with each other. As the system is implemented without sufficient preparation, it is incomplete and anticipatory side effects are expected in the future.
(3) Necessity of generalizing the life security monitoring system
Among the information generated from a home, a factory, an office, or a branch office, information that needs to be used at a remote location includes not only life security information about the use of electric power, water, and city gas, but also a lot of information related to safety or 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 life security information") is being generated daily at home. A large number of people want to get this vital security information from a remote place through a normal Internet network.
However, currently developed security system is a system that transmits certain information such as a passive infrared sensor or a house intrusion using a touch sensor to a specific location such as a security supplier 's office through a closed circuit. These systems have the disadvantage that they have limited use and are closed. Especially, since installation and service charges are expensive, most households can not use 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 generated, processed, and transmitted is high, the cost is also considerable, and thus it is not widely spread.
As described above, there is no technology that automatically generates various concentrated information related to security or safety in a home or a branch in real time and transmits the information in real time to a necessary place through a general internet network.
The existing remote automatic meter reading system and the security system have disadvantages that need to be individually improved, and they are constructed and operated as an independent system without any mutual connection, and there is a lot of inefficiency in system construction and operation, I did not let it.

According to the present invention, it is possible to combine the remote meter reading and the life security surveillance service separately operated in separate communication systems as one communication system.

Also, remote automatic meter reading for electricity, water, and gas can be integrally performed and managed, and various services related to security and safety for the user area can be provided as one integrated system at a time.
The information generated by the remote meter reading terminal and the life security monitoring terminal installed in the user area is simple and the amount of information to be transmitted to the relay is not so large. It is an amount of information that can be sufficiently transmitted by a conventional method. The optical wave communication system can be constructed and operated at a very low cost compared to the electromagnetic wave communication.

In addition, when transmitting information to the optical wave, directivity of the transmission / reception wave can be given by a simple method such as using a cone or the like.
In addition, since information is transmitted through the optical wave communication method to the repeater, the connection cost can be greatly reduced since the repeater is connected to the outside through the Internet or mobile communication network already installed in most user areas. have. In addition, since it is connected to the outside via the Internet or a mobile communication network, it is possible to generate, collect, and transmit information related to security / safety occurring in the user area in real time.
For the above reasons, it is possible to implement and install the remote meter reading and security monitoring system integrated into one system in the user's home or building at low cost, and the operation cost is also low.
In addition, the present invention provides the following advantages and effects:
(i) Detecting security / safety issues in the user area in real time and sending them directly to user, apartment management office, resident center, 119 system, 112 system, etc. It is convenient to link and operate, and it can support the security and safety of user area (home and branch office) in real time.
(ii) It is possible to collect, in real time, the usage amount of city gas correction volume from a meter or a volume corrector, and to correct the correction volume usage in real time in calories.
(iii) The life security monitoring sensor and the terminal can be miniaturized and can be implemented in a structure that can be moved and attached to a necessary place at any time. If necessary, it can be implemented in the form of a portable terminal.
(iv) It is possible to efficiently construct a repeater that processes and processes the vital security information received via the Internet or a mobile communication network, posts the information necessary for the user, or retransmits the information to the user and / or the persons concerned.
(v) Incidentally, the system supports bi-directional communication between home or branch offices and apartment management offices / municipal residents centers, making it easier to deliver announcements to residents at administrative offices.
(vi) In addition to correcting the volume of the city gas and correcting the calorific value, the real-time remote automatic meter reading can be accurately performed to provide relevant information to the city gas supplier efficiently and economically. This could end the very long controversy between the user and the supplier (the gas company) and the urban gas unfair fare problem, which is still unresolved, with an unfair tariff of about 250 billion won annually. In addition, it prevents the user from being charged an unreasonable charge, and the supplier can reduce the meter reading and the charging fee, which can lead to a discount of the city gas charge. In addition, it is possible to eliminate the inconvenience of the user due to the self-meter inspection system, and to prevent the disadvantage due to omission of the meter reading or the inspecting and inspection of the fare.

You can use frequency modulation of 'light' as a way to signal 'light'. In this method, (a) a signaling method according to the frequency of a light wave, that is, a method in which at least two first fundamental light waves having different levels of frequency are used, (b) a signaling method That is, a method (e.g., Morse coding) in which at least two or more second fundamental light waves having different frequency interruptions are used, (c) a method in which the above-mentioned functions are combined, And a method of constructing using basic optical waves together (e.g., Manchester coding).
The transmitted and received data can be composed of binary digital signals. Binary digital signals can be composed of 'bits' representing 0 and 1. A bit is a means of representing a minimum unit of information representing two kinds of states. In the present invention, a binary signal (that is, a bit) may be composed of, for example, two lights having two different arbitrary frequencies, or (2) ③ It can be composed more than four cases by combining them.
10 (a) and 10 (b) represent
A byte can consist of a collection of these bits. When a byte is composed of a group of bits, the number of bits constituting one byte can be arbitrarily configured. Depending on the frequency (including the relatively long frequency of the light), the byte may also be configured corresponding to the length of the light wave. At this time, the byte may correspond to a letter, a number, or a phoneme. The waveform diagram of FIG. 11 (a) shows a 5-byte waveform corresponding to ',,, a, he, and'. This makes it possible to construct a 'patent'. 11 (b) shows a 4-byte waveform corresponding to the numbers '2, 3, 4, and 6', and this waveform represents the number '2346'.
In the communication using the light wave, the waveform can be used in a quadrature, quadrature, or hexadecimal notation other than the binary notation. It is only necessary to provide wave types of light waves that can be distinguished from each other by the number corresponding to the desired convolution method. For example, a quadrature method may use a waveform having four different frequencies, or a method using four different waveforms having different waveform lengths.
In carrying out the conventional wave communication using the light wave, the data transmitted and received essentially or selectively include the following elements.
① Data start (Data_Start): Identification that starts sending, and it consists of one or more bits or bytes. This is an essential element.
② Data body (Data_Body): The data to be actually transmitted. It is an essential element and contains the information that the component has created or intended to deliver.
(3) Data end (Data_Stop): Identification that the transmission is completed, and it is composed of one or more bits or bytes. It is not an essential element, and it is also possible to identify that the transmission is stopped for a predetermined time or longer by a data end (Data_Stop).
④ Information about the 'shipping element' that performs the shipment. This information is not required and may be included in the above elements.
⑤ Information about the 'receiving element' that you want to receive. This information is not required and may be included in the above elements.
⑥ Information about the 'information communicator' that transmitted the relevant information at the previous stage of the transmission / reception. This information is not required and may be included in the above elements.
