Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic functional block diagram of a hand terminal for performing a method of changing and identifying a meter identification information according to the present invention, the key input unit 102 for inputting a user's command, for controlling all functions of the hand terminal. The microcomputer 104, the storage unit 108, the display unit 106, and a data transmission and reception unit 110 for transmitting and receiving data to a meter not shown in a wireless communication method.

2 is a flowchart illustrating a method of changing a meter identification information according to the present invention. The operation of the flowchart shown in FIG. 2 will be described with reference to FIG. 1.

If the user requests to change the meter identification information (hereinafter, referred to as ID) through the key input unit 102 while the initial menu screen is displayed on the display unit 106 of the hand terminal, the microcomputer 104 identifies the meter. The process returns to the information change mode and proceeds to step 201.

In step 201, the microcomputer 104 controls the display unit 106 to display an input request screen for the current ID of the meter to be changed and the ID to be changed. At this time, the cursor is located at the current ID to indicate that the current operation mode of the hand terminal is a mode for inputting the current ID.

After displaying the input request screen for the ID in step 201, the microcomputer 104 proceeds to step 202 to check whether the operation mode of the current hand terminal is set to the change ID input mode. As a result of the check, since the current operation mode is a mode for inputting the current ID as described above, the operation proceeds to step 203.

In operation 203, the microcomputer 104 checks whether the numeric key is controlled through the key input unit 102. As a result of the check, if the numeric key is controlled, the flow proceeds to step 204 to check whether the currently controlled numeric key is the ninth input numeric key. '9' is for checking whether the number information input exceeds the number of IDs assigned to each meter, and means that the number of IDs assigned to each meter is 8 digits. Therefore, when the information number of IDs assigned to the meter is changed, the above-mentioned '9' is changed to the number added with 1 to the changed number.

As a result of the check in step 204, if the currently input numeric key is not the ninth input numeric key, the flow proceeds to step 205 and stores the ID change as an ID of the desired meter. The storage is performed in the ID storage buffer set separately in the storage unit 108. The numerical information inputted in the current ID area (current ID: 0000 0000) displayed on the display unit 106 is sequentially displayed from the end digit so that the user can confirm.

In step 206, the display screen displays a current ID and a change ID input request screen in step 201, and then checks whether 15 seconds have elapsed. '15' seconds is to minimize the battery consumption due to the nature of the portable terminal, and if the above-mentioned ID input request screen is displayed for a long time and no action is taken, the operation mode of the hand terminal is turned off. Power Down) mode. Therefore, when 15 seconds have passed, as a result of the check in step 206, the process proceeds to step 207 to go to the power-down mode. The above-described '15 seconds' may be changed to any value that can satisfy the above-described minimization of battery consumption according to the number of information of the ID to be input and other operating conditions of the hand terminal. As a result of checking in step 206, the microcomputer 104 returns to step 202 when 15 seconds have not elapsed.

Steps 202 to 207 described above are repeated until all information corresponding to the ID (in this example, eight numeric information) is input.

As a result of the above repetition, if the currently input numeric information is recognized as the ninth input numeric information, the microcomputer 104 proceeds to step 208 and the ID storing buffer set in the storage unit 108. In step 206, all eight numeric information previously input is deleted, and the currently input numeric information is stored as the first ID information and displayed at the end of the current ID area on the display unit 106.

On the other hand, as a result of the check in step 203, if the key currently controlled by the key input unit 102 is not a numeric key, the microcomputer 104 proceeds to step 209 to check whether the cancel key. As a result of the check, if it is the cancel key, the flow proceeds to step 210 and sets the operation mode of the hand terminal to the menu selection mode before the meter ID change command is applied. As a result, an initial menu screen for selecting a different function is displayed on the display unit 106.

However, as a result of checking in step 209, if the cancel key is not controlled, the microcomputer 104 proceeds to step 211 to check whether the selection key is controlled. As a result of the check, if the selection key is not controlled, the flow proceeds to step 206 described above. This means that in the current ID input mode for changing the meter ID, control of keys other than the numeric keys, the cancel key and the selection key is ignored.

As a result of the check in step 211, if the selection key is controlled, the microcomputer 104 proceeds to step 212 and checks whether an ID stored in the ID storing buffer of the storage unit 108 exists. The check method recognizes that the stored ID exists if any data other than '0000 0000' is stored in the above-described ID storage buffer, and recognizes that the stored ID does not exist if '0000 0000' is stored. The aforementioned '0000 0000' may be changed according to the number of information of the ID.

As a result of checking in step 212, when it is recognized that the meter ID stored in the ID storing buffer of the storage unit 108 does not exist, the microcomputer 104 proceeds to step 206 described above. However, if the check ID of step 212 indicates that the meter ID stored in the ID storage buffer of the storage unit 108 exists, the flow proceeds to step 213 to position the cursor displayed on the display unit 106 in the change ID. In step 206, the operation mode of the hand terminal is set to the change ID input mode.

As a result of checking in step 206, if 15 seconds have not elapsed, the process returns to step 202 to check whether the current operation mode is the change ID input mode. Since the operation mode of the current hand terminal is set to the change ID input mode in step 213 described above, the microcomputer 104 proceeds from step 202 to step 214.

In step 214, the microcomputer 104 checks whether an arbitrary numeric key has been controlled. As a result of the check, if an arbitrary numeric key has been controlled, the microcomputer 104 proceeds to step 215 and after the currently controlled numeric key is set to the change ID input mode as in step 204, the ninth controlled numeric key. Check for acknowledgment.

As a result of the check in step 215, if the currently controlled numeric key is not the ninth controlled, the flow proceeds to step 216 to store the currently input numeric key in the change ID storage buffer set in the storage unit 108, Displays sequentially from the end of the change ID area displayed on the display unit 106. The process returns to step 202 through step 206. The above steps 202, 214 to 216, and step 206 are repeated until all eight digits assigned to the change ID are input.

As a result of the check in step 215, if the currently controlled numeric key is the ninth controlled numeric key, the microcomputer 104 proceeds to step 217 and changes the storage unit 108 storing all numeric keys inputted up to now. The ID storage buffer is cleared to delete all previously applied change ID information, and the currently input numeric key is stored as the first information of the above-described change ID storage buffer of the storage unit 108, while on the display unit 108. Displayed at the end of the change ID area. The flow proceeds to step 206 to repeat the above-described process.

On the other hand, as a result of checking step 214, if the numeric key is not controlled, the process proceeds to step 218 to check whether the cancel key is controlled. At this time, if the cancel key is controlled, the microcomputer 104 proceeds to step 210 and returns to the menu selection display mode displaying the initial menu screen before the meter ID change command is applied as described above.

However, if the cancellation key is not controlled as a result of the check in step 218, the flow proceeds to step 219 to check whether the transmission key is controlled. The transfer key is controlled when information related to the change ID is to be transmitted to the meter. Therefore, when the transmission key is controlled, the flow proceeds to step 220 and it is checked whether the change ID information is stored in the above-described change ID storage buffer of the storage unit 108. As a result of the check, if the change ID information is not stored, the flow proceeds to step 206. However, if the change ID information is stored, the flow proceeds to the meter communication mode of step 222.

If the transmission key is not controlled as a result of the check in step 219, the flow proceeds to step 206. This means that in the change ID input mode for changing the meter ID, other keys except the numeric key, the cancel key and the transmit key are ignored.

FIG. 3 is a flowchart illustrating a method of confirming change of a meter ID changed by FIG. 2.

First, after the meter communication mode is set in step 222 of FIG. 2, the microcomputer 104 proceeds to step 301 of FIG. 3 and transmits data regarding the changed ID to the data transmitting / receiving unit 110. That is, the data transmitting / receiving unit transmits a change ID stored in the change ID storage buffer of the storage unit 110, a command for requesting ID change, and a current ID of the meter to be stored stored in the ID storage buffer of the storage unit 110. Transmit via 110.

In operation 302, the operating mode of the hand terminal is set to the meter reading mode. In step 303, a meter reading request using the changed ID is requested. Metering mode setting and requesting are done in the same way as before. After the meter reading request, if the meter reading data is received through the data transmitting and receiving unit 110 in step 304, the microcomputer 104 proceeds to step 305 to control the display unit 106 to display the currently received meter reading data. . The indication is the metering data for the amount of usage sent with the changed ID. As such, the user may confirm that the ID of the corresponding meter is changed by the information displayed on the display unit 106. The display period for the meter reading data received on the display unit 106 is performed in the same manner as before, and when the display time ends, the microcomputer 104 terminates the meter ID changing operation.

As described above, the present invention is a method for changing the identification information (ID) of the desired meter using the hand terminal in the meter reading system that can read the meter by wireless communication method using the hand terminal By providing a, when changing the ID of the meter, there is an advantage that can be easily changed without directly operating the meter.
