{INSTALLATION STATE CHECKING, READ AND MAINTENANCE METHOD OF REMOTE METER RERING SYSTEM USING SMART DEVICE AND INSTALLER DONGLE}

The present invention relates to a smart meter and an installer dongle, and more particularly, to a smart meter and an installer dongle which are used for various functions (QR code, NFC, Bluetooth, Wi - Installation and inspection of remote meter reading system using smart device and installer dongle that can reduce time and cost problems caused by installation check, meter reading and maintenance using remote meter reading system in combination, And a method of maintenance.

Generally, meter reading objects such as water supply, sewage, electricity, and gas are inspected by visiting a home or a building, and the result is manually recorded or input to a portable terminal such as a PDA. Such a meter reading method is costly, inefficient, and requires a lot of time as the number of meter readers increases. In addition, there is a problem in that a check error is caused by a meter reading, a privacy invasion occurs, And input errors.

In order to solve this problem, a system has been proposed in which a meter connected to a network is used to meter an object to be inspected and the result of meter reading is collected. However, a meter object such as a water supply and sewerage, There is a problem in that it is not easy to install, maintain, manage, and repair. Accordingly, there is a demand for an automatic meter reading system that can easily install, maintain, manage, and repair various types of meter reading objects without being restricted by a communication network or a power source, and can overcome system errors.

Korean Patent No. 10-1213177 has been developed to solve these problems.

The prior art includes at least one meter reading unit including an RFID module for acquiring a meter reading value for a meter reading object, displaying the meter reading value, and wirelessly feeding a meter reading value in response to a meter reading value transmission request of the portable terminal, A repeater for acquiring and collecting a meter reading value by radio from the at least one meter reading unit at a time, and a control unit for receiving the meter reading value of the meter reading unit belonging to the repeater through the repeater, A concentrator for distinguishing a repeater and a non-repeater from each other, a repeater for which communication failure occurs, a concentrator for setting another repeater located closest to the repeater as an alternate repeater, and a radio communication with the concentrator to acquire a meter reading value And a control server for generating one of the billing information and the statistical information, Even if the meter reading object is in a position where the power supply and the network are not sufficiently provided, the meter object can be accurately measured at a remote place. Even if a part of the system components for meter reading is erroneous, So that the value can be obtained.

However, in the above-mentioned prior art, after all the setting information (periodic data transmission time, transmission order, device ID, etc.) of each installation device (collector, repeater, There is a problem that it is difficult to correct the information of the device or to map the installation area information to the map due to the functional limitation of the portable terminal, It is impossible to confirm whether the installed remote meter reading system is normally operated. After installing each device, it is necessary to confirm that the initial data of each device (mainly 4 hours or 6 hours intervals) There is a problem that the abnormality of the connection of the meter reading network can be confirmed, If there is an error in the installation, the re-installation worker is put into the site where the problem occurs, and there is a problem that it is necessary to wait until the initial data comes into the server again after confirming the configuration of the meter network and the abnormality of each device, This installation process has a problem that the remote meter reading server has to repeatedly repeat until the entire data of each device is confirmed as normal. In contrast to the meter reader (collector) installed in each customer, In the case of a repeater or concentrator installation in which the number of installations can be changed, there is a problem in that it is not easy to add and remove accurate information about the installation area of each apparatus in the field as needed.

Example 1: User Authentication Process of Smart Device and Installer Dongle (refer to FIG. 3)

First, it is assumed that a specific app is installed in the smart meter 101 for remote meter reading.

First, the specific app is started (S310), and it is determined by the dongle 210 whether the Bluetooth is paired between the smart meter 101 for the remote meter reading and the installer dongle 210 (S320).

If the Bluetooth is not paired in step S320, the smart meter 101 for remote meter reading fails to obtain the installer dongle key value from the installer dongle 210 in step S330. If Bluetooth is paired in step S320, the smart meter 101 for remote meter reading obtains an installer dongle key value from the installer dongle 210 (S340).

Thereafter, the obtained installer dongle key value and the specific manager key value of the RFID tag provided only to the specific manager of the smart meter 101 for smart meter reading are read in NFC (S350).

Then, it is determined by the installer dongle 210 whether the key value of the specific manager is acquired in the smart meter 101 for remote meter reading (S360).

If the key value of the specific manager is not obtained in step S360, the process returns to step S330. If the key value of the specific manager is obtained in step S360, the key value obtained from the installer dongle 210 The key value of the manager is transmitted to the remote meter reading server 106 (S370).

Thereafter, it is determined whether the key value obtained from the installer dongle 210 and the key value of the specific manager are valid in the remote meter reading server 106 (S380).

If the key value obtained from the installer dongle 210 and the key value of the specific manager are not valid in step S380, the process returns to step S330. In step S380, the key value obtained from the installer dongle 210 The administrator mode is started (S390), and the user authentication process between the smart device 101 and the installer dongle 210 is completed.

If the key value obtained from the installer dongle 210 and the key value of the specific manager are valid, it is determined whether the key value obtained from the installer dongle 210 and the key value of the specific manager are received, After the values are stored, authentication according to the determination result is transmitted.

Embodiment 2: The user authentication process of the remote meter reading server (refer to FIG. 4)

At step S410, the remote meter reading server 106 receives a request to authenticate whether the dongle key value and the key value of the specific manager are valid with the installation obtained from the installer dongle 210. [

Thereafter, it is determined whether the dongle key value and the key value of the specific manager are the registered key values by the installation obtained from the installer dongle 210 by the remote meter reading server 106 (S420).

If the dongle key value and the key value of the specific manager are not the registered key values in the installation acquired from the installer dongle 210 in step S420, an authentication error message is transmitted to the installer dongle 210 (S430). If the dongle key value and the key value of the specific manager are the registered key values in the installation obtained from the installer dongle 210 in step S420, an authentication message is transmitted to the installer dongle 210 by the remote meter server 106 (S440).

Then, the user log information is stored in the remote meter server 106 (S450), and the user authentication process of the remote meter server is completed.

Here, in step S450, the user log information is stored, and the installation obtained from the installer dongle 210 allows the specific administrator to access the site through an arbitrary installer dongle through the dongle key value and the key value of the specific manager It is identified whether it was accessed.

Embodiment 3: Individual recognition and designation process of each device (refer to FIG. 5)

Thereafter, the QR code attached to the front face of the specific device photographed is recognized through the smart device 101 (S520). At this time, the smart device 101 recognizes the device individually through the QR code.

Thereafter, the ID and change information of the specific device photographed separately by the smart meter 101 for remote meter reading are transmitted to the installer dongle 210 (S530).

Thereafter, the installer dongle 210 transmits a request to store the change information to the individual device that has been photographed and photographed (S540).

Thereafter, the smart device 101 transmits a message that the individual recognized and photographed specific device has stored the change information (S550), and the individual recognition and designation process of each device is completed. At this time, a message indicating that the change information has been stored in the smart device 101 is output.

In step S540, a preamble is performed between the installer dongle 210 and the meter before the installer dongle 210 transmits a request to store the change information to the meter.

Further, by this individual recognition and designation process, additional or changing information of each device input to the smart device can be stored in each device through the installer dongle if necessary. In addition, it is possible to store setting information or to read stored information into a smart device by designating specific devices through a recognized or already known ID.

At step S630, at least one specific device selected from the remote collector 102, the remote relay 103, and the remote concentrator 104 is photographed with the smart meter 101 for remote meter reading.

Then, the ID information of the specific device photographed is transmitted to the smart device 101 (S640).

After that, the smart meter 101 for remote meter reading requests location registration (ID information of the photographed specific device, current GPS information) to the installer dongle 210 (S650).

Then, the installer dongle 210 requests location registration (ID information of the photographed specific device, current GPS information) to the remote meter reading server 106 (S660).

Thereafter, it is confirmed whether the ID of the specific device photographed by the remote meter reading server 106 is registered (S670). At this time, the current GPS information is stored in the remote meter reading server 106.

Thereafter, the remote meter reading server 106 notifies the installer dongle 210 that the location registration is completed (S680).

Thereafter, the installer dongle 210 notifies the smart meter 101 for remote meter reading that the location registration is completed (S690), and the installation area location information check and check process is completed. At this time, a message indicating that the location registration is completed is output to the smart meter 101 for remote metering.

In step S610, S620, S650, and S690, communication between the smart device 101 and the installer dongle 210 is performed through Bluetooth.

In step S660 and step S680, the CDMA is turned on and communicated between the installer dongle 210 and the remote meter reading server 106 through the CDMA network.

When the step S680 is completed, the CDMA is turned off.

Embodiment 5: The meter reading and status information request process (see FIG. 7) of each device (remote collector, remote repeater, and remote concentrator)
Here, the upper device refers to devices that are advanced from the remote collector 103 to the remote meter reading server 106, and the remote meter reading server 106 is a higher level device than the remote concentrator 104. The remote concentrator 104, (103) and the remote repeater (103) is an upper device rather than the remote collector (102).

First, the smart meter 101 for the remote meter reading requests the meter or status information to the installer dongle 210 (S710).

Thereafter, it is determined whether the installer dongle 210 is the meter reading information or the status information (S720).

Thereafter, the installer dongle 210 requests meter reading or status information to any one of the upper devices selected from the remote collector 102, the remote relay 103, and the remote concentrator 104 (S730).

Thereafter, the upper device receives meter reading or status information from the installer dongle 210 (S740).

Thereafter, the upper device requests the lower device for meter reading or status information (S750).

Thereafter, the lower device provides meter reading or status information to the upper device (S760).

Thereafter, the upper device provides meter reading or status information to the installer dongle 210 (S770).

Thereafter, the meter reading or status information is stored in the FRAM 214 of the installer dongle 210 (S780).

Thereafter, the installer dongle 210 provides the meter reading or status information to the remote meter reading smart device 101 (S790), and the meter reading and status information request process is completed.

In step S730, the preamble proceeds between the installer dongle 210 and an upper device before the installer dongle 210 requests inspection or status information from the upper device.

Also, in step S750, the preamble proceeds between the upper device and the lower device before the upper device requests inspection of the lower device or status information.

Further, in steps S710 and S790, the communication between the smart device 101 and the installer dongle 210 is performed via Bluetooth.

In steps S730, S750, S760, and S770, the communication between the upper device and the upper device and the communication between the upper device and the lower device is performed via the RF.

Each device periodically has a command reception wait time for waiting for command reception, and each device receives information corresponding to the command reception wait time.

Example 6: Data collection from each device (remote collector, remote repeater and remote concentrator) (see Figure 8)

First, the installer dongle 210 requests the remote collector 102, the remote relay 103, and the remote concentrator 104 for meter reading data (S810).

Then, the remote collector 102, the remote relay 103, and the remote concentrator 104 receive the metering data request information (S820).

Thereafter, the meter reading data is transmitted between the remote collector 102, the remote repeater 103 and the remote concentrator 104 and the installer dongle 210, and the ACK indicating that the meter reading data has been received proceeds several times (S830) .

Thereafter, the inspection data is stored in the FRAM 214 of the installer dongle 210 (S840).

Thereafter, the installer dongle 210 notifies the remote collector 102, the remote relay 103, and the remote concentrator 104 that the collection of the meter reading data is finished (S850).

Then, the Wi-Fi Direct module 213 of the installer dongle 210 is turned on (S860).

Thereafter, the installer dongle 210 transmits the collected meter reading data to the smart device 101 as Wi-Fi Direct (S870).

Thereafter, the smart meter 101 for remote meter reading informs that the transfer of the meter reading data collected by the installer dongle 210 is completed (S880).

Thereafter, the Wi-Fi Direct module 213 of the installer dongle 210 is turned off (S890), and data collection from each device is terminated.

In step S810, the remote collector 102, the remote relay 103, and the remote relay 103 are connected to each other before the installer dongle 210 requests the remote collector 102, the remote relay 103, And the preamble proceeds between the remote concentrator 104 and the installer dongle 210.

Each device periodically has a command reception wait time for waiting for command reception, and each device receives information corresponding to the command reception wait time.

In the installation inspection, meter reading and maintenance method of the smart meter and the installer dongle according to the present invention, when the remote collector can receive the meter from the meter even if the communication problem occurs, the remote controller periodically receives the current value of the meter, So that the meter reading history and the log can be confirmed by reading the memory data of the corresponding remote collector in the future.

In order to solve the problem in transferring a large amount of meter reading data, a large amount of data with a data size of 1 KB or more is first stored in the internal FRAM of the installer dongle via RF, and then, Wi-Fi Direct can be used to send to a smart device quickly.

In addition, Wi-Fi Direct is normally activated by power down to prevent battery consumption, and is activated only when a large amount of data is transmitted to transmit the large amount of data to the smart device, After that, it switches to power down. When transmitting a small amount of data, status information can be confirmed by Bluetooth.

Although the FRAM is used as the internal memory of the installer dongle in the embodiment of the present invention, it is needless to say that it can be replaced with a memory card.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Various changes, modifications or adjustments to the example will be possible. Therefore, the scope of protection of the present invention should be construed as including all changes, modifications, and adjustments that fall within the spirit of the technical idea of the present invention.
