The magnetic sensor 12 is installed on the body 1 of the meter 10 to measure the magnetic force intensity and realizes the measured magnetic force intensity to the controller 15 in real time.

The magnetic sensor 12 described above is preferably installed so as to face a magnet (not shown) built in the sealing device 11 when the lid 5 is coupled and sealed to the body 1 of the meter 10 Do.

The short-range wireless communication unit 13 takes charge of communication with the external device 20 in accordance with the short-range wireless communication system, and stores the weight value which the control unit 15 periodically weighs and delivers.

In addition, the short-range wireless communication unit 13 monitors the control unit 15 and stores seal release event information under the control of the control unit 15. [

The short range wireless communication unit 13 transmits various commands and setting information received from the connected external device 20 to the control unit 15 according to the short range wireless communication method, 15 or the local wireless communication unit 13 itself to the external device 20. [0050]

The short-range wireless communication unit 13 may be implemented as a Bluetooth module, a Zigbee module, or an NFC (Near Field Communication) module.

The short-range wireless communication unit 13 may be physically located on a printed circuit board (PCB) with the controller 15 to perform direct data communication.

The usage measuring unit 14 periodically measures the usage amounts of electricity, gas, water, and the like, and applies a metering value according to the measurement to the control unit 15. [

The control unit 15 sets the magnetic force intensity measured through the magnetic sensor 12 as a reference value according to the reference value setting command transmitted from the connected external device 20 according to the short-range wireless communication method. At this time, the meter 10 is sealed with the sealing device 11 containing a magnet (not shown).

As described above, the magnetic sensor 12 is installed so as to face a magnet (not shown) built in the sealing device 11 when the lid 5 is coupled and sealed to the body 1 of the meter 10 The distance between the magnetic sensor 12 and the magnet (not shown) does not change in the state where the lid 5 is normally engaged and sealed in the body 1 of the meter 10. Therefore, The magnetic force intensity that is the same as the value set by the magnetic force detection unit.

However, when the user opens the lid 5 to unintentionally operate the meter 10, the distance between the magnetic sensor 12 and the magnet (not shown) increases, and the magnetic force 12 measured through the magnetic sensor 12 .

Accordingly, the control unit 15 detects the seal release of the meter 10 by comparing the magnetic force intensity measured in real time with the reference value through the magnetic sensor 12, and when the magnetic force intensity measured through the magnetic sensor 12 is larger than the reference (For example, 3 seconds or longer), it is determined that the seal of the meter 10 is released.

As described above, when it is determined that the sealing of the meter 10 is released, the controller 15 determines that the user has opened the cover 5 to unintentionally operate the meter 10, , The weighing value and time at the time when the seal is released is stored, and the seal release elapsed time is counted and recorded.

Further, if it is determined that the seal of the meter 10 is released, the control unit 15 may be configured to stop all the measurements.

If it is determined that the seal of the meter 10 is released, the control unit 15 transmits a seal release event to the near-field wireless communication unit 13, and also stores seal release event information in the memory provided in the near- Save the weighing value and time at the time when the seal is released.

The control unit 15 stores the metering value measured at the predetermined period in the usage memory 14 through the usage measuring unit 14 in the self memory and transmits the measured value to the near field wireless communication unit 13, It is stored as a double.

The control unit 15 causes the meter 10 to operate by battery power when the power is turned off and transmits the measured value measured at a predetermined cycle to the near field wireless communication unit 13 via the usage amount measurement unit 14, And stores it in a memory provided in the wireless communication unit 13. [

As described above, the short range wireless communication unit 13, which stores the metering value under the control of the controller 15, transmits the stored data stored in the memory to the controller 15 when there is a request for storing data from the controller 15 .

The display unit 16 displays various status information of the meter 10 and displays the current time, the weighing value, the seal release elapsed time, and the like.

When the controller 15 detects the unsealing, the controller 15 displays the unsealing status through the display unit 16 so that the administrator can confirm the unsealing status.

2 is a view illustrating an example of a display screen applied to the present invention.

2, the current time display unit (a) displays the current date (YYYY / MM / DD) and the current time (HH: MM: SS).

The weighing value display portion (b) displays the weighing value measured by the usable amount measuring portion (14).

The seal release elapsed time display section (c) displays the seal release elapsed time after the seal is released.

FIG. 3 is a process chart for explaining a method of controlling a meter for preventing irregularity according to an embodiment of the present invention.

First, the meter 10 is sealed by using a sealing device 11 in which a magnet (not shown) is embedded in a state where the body 1 of the meter 10 and the lid 5 are fastened.

Thus, when the meter 10 is sealed by the sealing device 11, the meter manager drives the meter management application mounted on the external device 20, and controls the external device 20 to the meter (not shown) 10.

As described above, when the external device 20 is connected to the meter 10 in accordance with the short-range wireless communication method (S10), the meter manager sends a reference value setting command (command) to the controller 15 of the meter 10 via the meter management application (S12). Upon receiving the reference value setting command, the controller 15 sets the magnetic force intensity measured through the magnetic sensor 12 as a reference value (S14).

The control unit 15 then compares the reference value set in step S14 with the magnetic force intensity measured in real time through the magnetic sensor 12 to determine the unsealing of the meter 10. The control unit 15 controls the magnetic sensor 12), it is checked whether the state in which the magnetic force intensity measured in real time falls below the reference value and the state in which the magnetic force intensity falls below the reference value is maintained for a preset time (for example, 3 seconds) (S16).

If it is determined in step S16 that the magnetic force intensity measured through the magnetic sensor 12 does not fall below the reference value and the magnetic force intensity falls below the reference value for a predetermined time (for example, 3 seconds) If it is determined that the sealing of the meter 10 has not been released (S16: NO), the control unit 15 stores the metering value measured at a predetermined cycle through the usage measuring unit 14 in its own memory, And transmits it to the communication unit 13 and stores it in a memory provided in the short-range wireless communication unit 13 (S18).

On the other hand, if it is determined in step S16 that the magnetic force intensity measured through the magnetic sensor 12 falls below the reference value and the magnetic force intensity falls below the reference value for a predetermined time (for example, 3 seconds) If it is determined that the seal of the meter 10 is released (S16: YES), the controller 15 stores the seal disconnection event information in its own memory, and requests the seal disconnection event storage by the short-distance wireless communication unit 13 The short-range wireless communication unit 13 stores the seal release event information in its own memory (S20).

In the process S20, the controller 15 may store the weighing value at the time when the seal is released and the time when the seal release event information is stored.

The control unit 15 counts and records the seal release elapsed time when the seal release is detected through the process S16 and displays an alarm related to the seal release such as the seal release elapsed time on the display unit 16, The manager intuitively recognizes that the sealing of the seal 10 is released (S22).

After the seal is released, the usage amount measuring unit 14 normally measures the usage amount of electricity, gas, water, etc., however, the control unit 15 may display only the alarm related to the seal release on the display unit 16. [

As described above, the administrator who has confirmed that the seal is released through the seal release related alarm displayed on the display unit 16 drives the meter management application installed in the external device 20, and controls the external device 20 in accordance with the short- The control unit 15 sends the seal release event information and the accumulated measurement data stored in the memory 15 to the external device 20 ).
