Description

A method of operating a meter reading network using a CD network and its operating system.

The present invention relates to a method of operating a meter system using a CDMA PCS network and its operating system. More specifically, the PCS (Persnal Communication Service) to a common controller that receives and stores the data values of the meter installed in each home from the home controller The present invention relates to a method of operating a meter reading network using a CDMA PCS network and a system for attaching a terminal module to wirelessly transmit the accumulated data to the operator to operate the meter reading network using the CDMA PCS network.

The code division multiple access (CDMA) communication system to which the present invention is applied is a wireless mobile communication method developed to be suitable for voice and data transmission through a PCS terminal. It is a system that enables bi-directional communication with PCS terminal module.

Generally, a meter meter (meter) installed in each home or business place is an integrated power meter (electric meter). In addition to integrated power meters, there are water meters, city gas meters and heat meters. Therefore, each electricity provider or water company city gas operators need to manage the meter network formed in the country.

The conventional method of operating the meter system is a general manual method and a method by remote control. In the case of the manual method, a meter reader of a business operator (electricity provider, water service provider ...) visited each household, observed the meter directly, recorded the usage, and computerized the meter meter network. Accordingly, a double task was required, and there was a possibility that an error occurred in the metering process or the computerization process.

A more advanced method is that each meter reader uses a hand terminal to store data and inputs the stored information back into the computer network, but there is little improvement.

Conventional remote metering methods include a metering method using a TDMA or an analog vehicle and a method using a wired network. In the case of a remote metering method using a vehicle that is being executed overseas, such as the United States, the area to be read must first have a geographic condition suitable for moving the vehicle, such as an open area, and the meter should be installed in a space where radio waves can be easily received.

However, in Korea, the application of this method is unclear because it does not have an environment suitable for a method using a vehicle. The reason for this is that in urban areas, there are many mountainous areas or housing dense areas where vehicles are not suitable for operation, and the meter readings in each home are often installed in places where radio waves are difficult to reach.

In addition, there are two types of vehicles using a telephone line, a power line, a leased line, and a cable network. However, in the case of a telephone line, noise may be a problem, and power lines are difficult to implement and leased lines and cable networks nationwide. There is a problem that the practical time is very late due to the huge cost and time required to install in the home.

In addition, the TDMA or analog method, which is a wireless technology used in the conventional wireless remote meter reading method, is capable of transmitting a small amount of data, but it is known that the data transmission capacity is inferior to that of the CDMA technology. There is a problem in the method of managing the meter network by remote metering by analog method.

Therefore, the present invention solves the above problems, and the operators due to misreading by simplifying the complex multi-step procedure for many hours and the time required to start the meter reading and completion of the meter reading nationwide. (Korea Electric Power Corporation, City Gas Corporation .. Money can be minimized, and early service is possible by using CDMA-type PCS mobile communication system that has already been established nationwide, and can monitor and control the status of meter reading in real time to prompt action in case of problems. The purpose of the present invention is to provide a method of operating a meter reading network using the CDMA PCS network and its operating system.

1 shows an integrated power system network operating system using a CDMA PCS network according to an embodiment of the present invention. As shown, there is an integrated power meter installed in each home to check the power consumption of the home, and the integrated power meter 10 of each home is controlled to extract or integrate the integrated power data from the integrated power meter 10 of each home. A home controller 20 is installed in each home to control the operation of the power meter 10.

The home controllers 20 of the respective homes are connected through wires to periodically receive data of the integrated power meter of each home from the plurality of home controllers 20, and store the data for each home controller. The joint controller 30 is installed in the outdoor telephone pole to control the.

The integrated power meter data stored in the common controller 30 is wirelessly transmitted to the operator via the CDMA PCS network based on the polling of the operator, or the control signal of the integrated power meter is wirelessly transmitted from the operator to the joint controller 30. PCS terminal module 40 is installed on the outdoor telephone pole.

Through the multiple PCS terminal modules installed in the outdoor telephone pole, connected to each of the common controller 30 via a CDMA PCS network (including a central server of the mobile communication operator) and integrated from each common controller 30. The network management center 60 is provided with a network management server for controlling the operation of peripheral devices leading to the power meter 10 and wirelessly receiving the results thereof to control the integrated power meter network. It is composed of an operator who can connect to the server of 60 and check the integrated power meter of each household or perform various other tasks remotely.

In accordance with the above configuration, each domestic integration provider is suitable for use in low voltage meter supply to general households by domestic electricity supplier that wirelessly reads analog integrated power meter (electric meter or meter) by using wireless data service. Connect a home control unit (HCU) device to a power meter or meter, and periodically transfer and save electricity usage data to a common control unit (CCU), and move the CDMA-type PCS connected to the common controller. The communication terminal module transmits the data message to the central operating server of the PCS mobile communication service provider through the CDMA type PCS mobile communication system, which is commercially available nationwide, and transmits the data message to the central operating server of the electric service provider. Stores data messages in its own database and stores each PCS By polling the number assigned at the end, the accumulated data value in the common controller installed at each point is received as wireless data through the PCS terminal module.

2A illustrates a method of operating an integrated power system network using an integrated power system network operating system using the CDMA PCS network. As shown, the integrated power grid operating method according to the present invention is performed by performing the integrated power meter data collection step (S10) and integrated power system network control step (S20).

In the integrated power meter data collection step (S10), the integrated power meter is extracted from the integrated power meter 10 in each home through the home controller 20 installed in each home, and the common controller 30 installed in the outdoor telephone pole through the wire. It transmits periodically and stores by each home controller, and wirelessly transmits to the server of the network management center 50 via the CDMA PCS network through the PCS terminal module 40 connected to the common controller based on the polling of the operator. Collect data from each home's integrated power meter.

In the integrated power grid control step (S20), the power supply of the integrated power meter of each home is not limited to meter reading, and after the operator connects to the server of the network management center 60, the PCS terminal module 40 via the CDMA PCS network 50. To control the operation of the peripheral devices from each joint controller 30 to the integrated power meter 10 through wireless communication, and to wirelessly transmit the result to control the integrated power system network. Perform the process.

The integrated power meter data collection step (S10) is to poll the number assigned to the PCS terminal provided in the common controller to collect the integrated power meter data accumulated in the common controller installed at each point through the PCS terminal module. In the integrated power grid control step (S20), it is possible to control the state of the integrated power meter installed in each home, the state of the common controller, the state of the PCS module, the state of the transformer and the line state.

As shown in FIG. 2B as a detailed step of the integrated power meter data collection step S10, data extraction step S11 of the home controller HCU and data transmission to the common controller CCU, and data in the common controller CUU.

In the data storage step S12 in the common controller CUU, data of the integrated power meter transmitted from the home controllers is stored in the memory of the common controller for each home controller. At this time, it has an address value indicating each home controller in the header of the stored data so that it can know which data is transmitted from the integrated power meter of the home, so that it is possible to store information about the measurement time and measurement value information.

In the step of wireless transmission through the PCS terminal module (S13), the server of the network management center via the CDMA PCS network through the PCS terminal module 40 based on the polling of the integrated power meter stored in the common controller 30 through the operator's polling. Wirelessly transmit to 50.

3 shows a process of extracting data from the integrated power meter until the operator completes the remote meter reading. As shown in the drawing, digital values are first extracted from an integrated power meter installed in each home, and data is transmitted through a common control unit (CCU) installed in an outdoor telephone pole through a wire (111).

When data values from up to 100 home controllers 20 in charge of one common controller 30 are periodically transmitted to the common controller 30, these values are stored as digital values in a memory in the common controller 30. The stored data has an address value indicating each home controller in the header so that it is possible to know which data is transmitted from the integrated power meter of the home. In addition, the stored data has information on measurement time and measurement value information. The data transmitted and stored from each home controller is stored and stored in the memory in the common controller for a predetermined time (112).

In addition, each common controller has a built-in CPU to control the entire meter reading function and execute the operator's command, and has a signal exchange function with the PCS terminal module for transmitting data wirelessly through the CDMA PCS network.

If the data saved in the common controller is requested from the operator for data transmission by polling the PCS terminal module through the CDMA PCS network (113), the PCS terminal module is connected to the common controller through the RS-232 port. When the transmission command signal is received, it is transmitted to the CPU of the co-controller, and the co-controller receiving the transmission starts to transmit the data stored in the wireless data via the PCS terminal module through the RS-232 port (114). These data are transferred to PCS network operator or server installed in KEPCO. The common controller performs a process of simultaneously checking whether the transmission is completed 115 while transmitting data in this manner. If the transmission is completed, the common controller automatically disconnects the operator and performs a function of receiving and storing data from the home controller at regular intervals again.

The operator can facilitate traffic management by making a data transmission command to the common controller by using the dawn time when PCS subscribers use the service the least, and the transmitted data is automatically input into the operator's computer network or KEPCO's computer network. All meter readings are completed (116).

In addition, the wireless data service is used to check the status of the unmanned integrated power meter and check the situation generated in an emergency. 4 illustrates a process in which an operator accesses a network management server and manages an integrated power meter network.

As shown, the operator accesses the data service from the network management center (121) and then accesses the wireless service from the network management center to the unmanned common controller (122). In the network management system, a specific operation for various peripheral devices of the integrated power meter connected to the common controller is designated (123). This specific operation may include each integrated power meter state, common controller state, transformer state, or line state. The common controller transmits the data stored through the PCS terminal module to the operator through a wireless data communication method (124). The operator determines the state of the integrated power meter and other situations from the received data and releases the connection to complete the check (125, 126).

The common controller module can configure several common controllers in an actual network configuration. Therefore, each common controller module includes a PCS module so that each home controller connected to the common controller can be connected by wireless data to each common controller module from the network management center. When an emergency occurs at a common controller or home controller at a particular point, the network management center attempts to access the data service wirelessly with the joint controller. After the connection, the network management of the common controller module is directly controlled. The network management center can unattended control and monitor the current situation as needed. Specifically, what control can be performed by the common controller module can be variously configured according to the installation of the home controller and the peripheral device.
