System for Providing Remote Service using Low Speed Dedicated Line Device {System for Providing Remote Service using Compact Communication Server}

The present invention relates to a remote service providing system using a low-speed leased line device, and more particularly, using a high-speed Internet (for example, cable modem, ADSL, wireless LAN, etc.) and a low-speed leased line device (CCS: Compact Communication Server). Provides communication services for power services, security communications for disaster prevention and disaster prevention, surveillance communications services for remote facilities, communications services for e-commerce systems, and additionally Voice over Internet Protocol (VoIP) and TCP / IP (Transmission). Control Protocol / Internet Protocol) The present invention relates to a remote service providing system using a low-speed leased line device that provides various services capable of connection.

Recently, due to the development of the Internet and the rapid spread of the World Wide Web, there are many changes in the way of distributing information in the present society, especially in the society where information is important, such as modern society. Obtaining more accurate information is becoming a key factor in competitiveness. Due to this phenomenon, the rapid propagation of information through the Internet, and the Internet is regarded as an important development in terms of sharing and disseminating various information. As a result, demand for more advanced Internet services has increased along with a surge in demand for Internet services worldwide since the 1990s. For many years, a major concern in establishing high-speed information networks for most network operators, telecommunications companies and subscriber network operators has been to provide Internet services for subscribers to use the Internet cheaper and more efficiently. Therefore, the most important thing is to provide the Internet service and the future comprehensive multimedia service while constructing the information communication network most economically.

However, since the conventional remote service providing system (eg, remote meter reading system, security and disaster prevention system, e-commerce system, etc.) provides a service using a PSTN modem or a Digital Service Unit / Channel Service Unit (DSU / CSU). The service speed and data transfer rate were considerably lowered, which resulted in a problem in that speedy download and data processing could not be performed smoothly. For example, in the conventional remote meter reading system for energy consumption, wired / wireless modems are used for data exchange between a meter and a mobile communication network or a PSTN. However, conventional wired / wireless modems merely relay data exchanges. Because only the role plays a role, the transmission speed due to data exchange is relatively low, and there is a problem in that the operation state of the wired / wireless modem cannot be accurately understood. In particular, in the case of a wireless modem, unlike a wired modem, since data is exchanged using a specific frequency, there is a high possibility of causing confusion with adjacent frequencies, and it is difficult to accurately diagnose various error sources. Doing.

In addition, in operating each remote service providing system, data communication is inefficient by connecting different communication networks to each terminal having a different communication method, and a double investment cost for setting a communication line as a dedicated line for a specific service. And the inefficiency of the line is a problem.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is a variety of terminals (for example, electronic meters, facility monitors, card terminals, security equipment, unmanned automated equipment for banks, etc.) It is to provide a remote service providing system using a low-speed dedicated line device that provides high quality service at no additional cost by processing data exchange with and compatible data transfer quickly and accurately to a desired destination through a built-in high-speed Internet network. .

Another object of the present invention is to exchange data with each terminal in the serial communication, equipped with a remote monitoring and management function of the equipment status, the stability and security of the data transmission, automatic hardware reset function, etc. The present invention provides a CCS (Compact Communication Server), which is a low-speed leased line device that relays data between terminals and additionally provides various services through Internet telephony service and TCP / IP connection.

And a relay role for transmitting the unique ID information to the communication network 300 through the Internet cable modem. In addition, the CCS 100 performs a remote monitoring and management function to support the monitoring and management of the equipment status from the outside using SNMP, a simple network management protocol, to perform stable data communication using SSL, and to use an encrypted authentication code. Data transfer stability and security, data reset period (e.g. Default: 1 hour minimum 15 minutes, maximum 24 hours, 96 steps) and hardware reset function at the set intervals, etc. are included. .

Here, the electronic meter (including the semi-electronic meter) digitally measures the energy usage of the consumer and stores it in the internal memory, and when the reading of the meter data transmission command is received, the electronic meter (including the energy usage) It sends a unique ID of the customer. Electronic meters should be installed alone in single-phase two-wire circuits to enable metering of effective power over time and recording of all data, and remote meter reading should be possible by attaching a removable modem to the instrument. In addition, the facility monitor (including an environment monitor) includes various terminals (eg, switchgear) necessary for environment and facility monitoring, and stores the acquired monitoring data and transmits the monitoring data to a designated path upon external request. .

It is a broad network that means a high speed internet network including a back light. Currently, the communication network 300 is established in most regions of the country, and is constructed as a subscriber network infrastructure following the telephone line. Based on this infrastructure base, there is an advantage that the low-speed leased line service that requires a large number of CCS 100 in a large area can be applied to the communication network (300).

The CMTS 400 converts modem data into Internet data packets, and conversely, converts Internet data packets into modem data. The CMTS 400 includes a routing function for storing local data in the cable system, a filtering function for protecting cable operators from unwanted hacking, a traffic specification function for ensuring a quality of service, and the like. That is, the CMTS 400 serves to interface the data format between the communication network 300 and the FEP 600 described later.

The DHCP server 500 automatically assigns an IP address for executing TCP / IP communication. DHCP is a communication protocol for automatically allocating and managing configuration information necessary for executing TCP / IP communication, and is defined in RFC 1541. The DHCP server 500 provides a uniform management service of IP addresses in a communication network of a TCP / IP environment. DHCP is a protocol on the User Datagram Protocol (UDP), similar to the Initial Load Protocol (BOOTP), and the DHCP server automatically assigns an IP address in response to a request of a DHCP client (eg, FEP 600).

The FEP 600 is connected to the communication network 300 and has the expandability to mount up to four communication processing modules capable of accommodating up to 16 dial-up lines, TCP / IP, SLIP, PPP, and Async. It supports protocols and exchanges data with the CCS 100 through the communication network 300, and performs a function of minimizing problems due to communication equipment and line failures. In addition, by monitoring the status of each port, the cause of the problem can be accurately and quickly determined, and the modem is initialized automatically after the meter is executed to prevent the modem's hang-up state in advance, and the meter data from the electronic meter is measured. Alternatively, if the data is damaged by the noise or communication distortion of the modem or line used in the process of acquiring the monitoring data (hereinafter referred to as 'measurement data') from the facility monitor, an alarm message is immediately sent to the administrator. do. In addition, it receives and automatically sets initial information such as the CCS 100 unique ID, meter reading period, and instrument unique number from the AMR server 800, and automatically sets meter reading data obtained from the CCS 100 (e.g., LAN ( 700)] to the AMR server 800. Module-specific functions of the FEP 600 will be described in detail later with reference to FIG. 4.

The AMR server 800 is interconnected with the FEP 600 through the LAN network 700 and manages the database 900. The AMR server 800 is a server that manages the connection and transmission and reception of customer information and meter data with the tariff management system of the main computer. And manages meter reading data received from the FEP 600. In addition, the AMR server 800 has a daemon-type process for creating, automatically updating, and reading and managing statistics for a customer master database using database information received from the host computer. It is included. All functions necessary for communication in the AMR server 800 are implemented to be processed in software, and the function of each module of the AMR server 800 will be described later in detail with reference to FIG. 5.

4 is a functional block diagram of the FEP 600 according to the present invention. The FEP 600 is operated by software (eg, 'PowerAMR') capable of processing a telemetering task, and can accommodate up to 64 circuits. By connecting up to 6,000 CCS (100) in connection with a communication conversion device that can be able to respond flexibly to customer growth. Different communication methods can be set for each port to accommodate the CCS 100 supporting different communication methods in one FEP 600.

The dial processing module 610 configures a communication path with a plurality of CCSs 100 connected by a modem in connection with the communication converter 670 through TCP / IP, and provides a function of acquiring meter reading data from the CCSs 100. As a module, up to 64 dial processing modules 610 can be driven dynamically. The modem is initialized automatically after the meter reading is executed to prevent the hang-up state of the modem.

The communication processing module 620 is a module that communicates with the communication processing module of the FEP software (that is, PowerAMR) in a TCP / IP manner, and transmits data acquired and interpreted from the dial processing module or the packet daemon module 660 to TCP / IP. It performs the function of transmitting to the AMR server 800 in a manner. In addition, the communication processing module 620 determines whether the PowerAMR 695 successfully acquires data, requests retransmission when an error occurs, matches data between the PowerAMR 695 and the FEP 600, and sets the protocol of the CCS 100. Convert, process, interpret, convert to the same protocol to communicate with the AMR server 800.

The data management module 630 is a module for acquiring, interpreting, and storing meter reading data from the CCS 100. The data management module 630 supports data acquisition and analysis according to each CCS 100, and when data is acquired from the CCS 100. In order to ensure the reliability of the CRC and BCC is generated at the time of transmission, the CRC and BCC error check to determine whether there is an error of the data obtained by the error check and resend when an error occurs. To speed up data read / write, DAO (Date Access Object) method is used to process data quickly. It is desirable to include a function of mutual matching with the memory portion of the CCS 100 to improve data reliability.

The schedule processing module 640 may vary up to 24 hours with the basic meter reading cycle as 1 hour, and accommodates up to 6,000 CCSs (100) on a maximum of 64 lines for automatic meter reading on a regular meter reading day. In addition, the metering scheduling for data acquisition may be differently set for each customer in a periodic polling scheme, and a processing schedule for occurrence of data acquisition error of the CCS 100 may be simultaneously operated. The customer-specific meter schedule schedule data is constructed by receiving or collectively receiving initial information such as line number, meter reading period, instrument manufacturer and number from the PowerAMR 695 at the start of the FEP 600 to establish a dial-up meter reading path. The schedule change of the PowerAMR 695 may be applied to the schedule processing module 640 in real time or may be arbitrarily changed by an administrator.

The failure management module 650 is a module that converts communication and other equipment that does not support the SNMP protocol as network equipment that supports the SNMP protocol. The communication status of the CCS 100 connected to each port of the communication conversion apparatus 670 may be checked on the management screen of the PowerRMS 680, which is a resource management software on the AMR server 600. Accordingly, the operation state and resource information of the FEP 600, the operation state and resource information of the modem are transmitted to the PowerRMS 680 by using the failure management module 650 to perform effective management. IP allocation in the fault management module 650 is automatically assigned at the time of initial registration of the schedule data.

The packet daemon module 660 is a daemon process that receives meter reading data in association with TCP / IP. The packet daemon module 660 communicates with the CCS 100 at a set cycle using a packet method. In order to communicate with multiple CCS 100 at the same time using a dynamic replication method can minimize the bottleneck of communication to reduce the loss of meter reading data.

All functions necessary for the communication in the AMR server 800 are implemented to be processed in software. The AMR server software is a client module (PA-CLT). ) 810, server module (PA-SVR) 820, communication processing module (PA-FEPC) 830, master management module (PA-MST) 840, schedule management module (PA-SCHD) 850 ), A DB management module (PA-DBMS) 860, a meter management module (PA-MDPR) 870, and a meter control module (PA-MCPR) 880.

The client module 810 and the server module 820 are remote meter reading client / server software. The module is developed as a GUI environment so that users can easily use the meter data inquiry, various statistical data inquiry, and instrument control commands. Basic tool to use.

The PA-FEPC 830 is a communication processing module that interlocks with the FEP 600 to acquire meter reading data quickly and efficiently to realize load control. The communication with the FEP 600 is operated as a daemon process in the form of a server, and in order to minimize the bottleneck of the server due to the expansion of the FEP 600, the time gap between the communication processing and the data processing is eliminated by using the dynamic process generation technique. Implemented to immediately process the request of the FEP (600). In addition, it ensures reliable communication through the request for interpretation and retransmission of the CRC, and performs communication using a single protocol acquired by the FEP 600 from the various CCSs 100.

The PA-MST 840 is a master management module that constructs and manages a basic master of remote meter reading by using the basic information of the corresponding electronic meter or facility monitor obtained from the FEP 600 by storing and storing the database of customer information. Customer master information is newly created or updated to keep it up to date, and newly registered or updated details are preferably stored for at least one year so that the history can be managed.

The PA-SCHD 850 is a schedule management module that manages meter reading schedules. The PA-SCHD 850 may input, inquire, modify, and delete a meter manufacturer, a meter number, a meter reading period, a regular meter reading date, a meter reading priority, and the like. In addition, when there is a data request from the FEP 600, only the entire data or new data that is not synchronized may be selected and transmitted, and when the meter reading data received from the FEP 600 is different from the schedule DB, it is changed in real time. The data is retrieved and sent to the FEP 600 to keep the data consistent.

The PA-DBMS 860 is a module for storing and processing high-level data used for efficiently managing data. In order to use the database properly and effectively, the administrator requires considerable knowledge and experience. In order to prevent the loss of important data due to improper command processing, the DB management module 860 can back up, delete, and recreate the data. By providing GUI necessary parts for basic operation of the system, it supports the operator to easily manage the remote meter reading DB. In addition, the effective period of the data is set for efficient data processing and management, and the automatic deletion function is provided at the end of the period so that the proper capacity is always maintained. It also prevents missing pulse data in order to maintain the logical consistency of meter reading data, and supports continuous meter reading by automatically updating data when the instrument or modem is changed.

The PA-MDPR 870 stores and processes the data, stores the pulse data that has undergone the error verification process of the communication processing module 830 and the processed hourly, daily and monthly aggregate data in a database, and through a code conversion function. It is a meter reading management module that provides intermediate meter reading, periodic meter reading data, etc. as information for fee calculation. If a problem occurs during the data processing or abnormality of the reading data occurs, the operator is notified immediately and operated to take the necessary action immediately.In the case of regular reading, the meter is read automatically on the day using the control code of the customer number. If the meter reading fails due to a failure, operate it to update the meter reading DB by automatically rereading when the cause of the failure is removed. In addition, it analyzes the power failure of the instrument during pulse reading, periodic meter reading, or failure code of the instrument, and provides information on the cause of the failure so that the person in charge of the instrument can take immediate action.

PA-MCPR 880 is an instrument control module that can remotely clear the time set function and the failure of the instrument when the pulse time of the electronic meter or facility monitor is different from the specified time or the current time error occurs. This allows the administrator to perform the desired task remotely without visiting the site.

Hereinafter, an operation relationship of a remote service providing system using a low speed dedicated line device according to a first embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 6 is a flowchart illustrating the overall operation of requesting and transmitting reading data of a remote meter reading system according to a first embodiment of the present invention, and CCS assumes that an electronic meter or a facility monitor is connected and is an electronic meter in an AMR server. Alternatively, the data requested by the facility monitor is assumed to be 'metered data' measured by an electronic meter or facility monitor.

First, the AMR server periodically requests whether or not to use a data communication network to collect meter reading data through the LAN network through the Schedule Management Module (PA-SCHD), and the FEP sends data by the communication network to the meter reading request of the AMR server. Check whether communication is possible (S610). The AMR server communicates with the FEP through the communication processing module (PA-FEPC), and the communication with the FEP 600 is operated as a daemon process in the form of a server, and dynamic to minimize the bottleneck of the server due to the expansion of the FEP 600. It is desirable to use process generation techniques to eliminate time gaps in communication processing and data processing, and to handle FEP requests immediately. FEP can check whether TCP / IP communication is possible through a DHCP server that automatically assigns IP addresses. The FEP notifies the AMR server or administrator of the check of the line and modem if it is not in a communicable state, so that the FEP can maintain the communicable state within a short time.

If data communication through the communication network is possible, the FEP checks whether or not the meter can be read to collect the meter data with the CCS by pinging the CCS (S630). Similarly, the FEP notifies the AMR server or administrator of the inspection of CCS and modems unless they are available for meter reading so that they can remain meterable as soon as possible. Data communication between FEP and CCS through communication network is done through CMTS converting internet data packet and cable modem data. CCS receives the ping through remote monitoring and management interface and uses the SNMP to monitor the current status of CCS using SNMP. To pass. Communication through the network is done by polling method that inquires about data transmission from FEP to each CCS and authorizes communication when response signal comes from prepared CCS. CCS is TCP / IP stack supporting TCP / IP. Communicate with FEP via

If it is determined that the meter is in the readable state, the FEP requests the meter data transmission to the corresponding CCS including the ID of the specific CCS (S650). The CCS checks whether the corresponding metering request is a legitimate request through the data transmission stability and security interface unit (S660). The inspection of the legitimate metering request is carried out with the ID of a specific CCS included in the metering request data, and whether the transmitted CCS ID matches the own CCS ID stored in the memory unit can be determined as a legitimate metering request. . If it is not a legitimate metering request, the CCS notifies the error message to the FEP (S670) to induce a new metering request.

The CCS receives meter reading data (that is, meter reading data from the electronic meter or monitoring data from the facility monitor) requested by the electronic meter or the facility monitor and transmits the meter data to the FEP through a communication network (S680). The reading of the meter data of the CCS is performed through the communication interface. The FEP authorizes the meter data transmitted from the CCS to the AMR server through the LAN network, and the AMR server receives the meter data and stores it in the DB (S690).
