The control unit 131 is driven at the first time and the second time notified from the RTC unit 150 . Specifically, in the case of the remote meter reading mode, the control unit 150 wakes up at the first time and checks whether the same day is the meter reading day, and if it is the meter reading day, drives the camera 110 to display the meter image. After taking a picture and storing it in the memory 132 as the first meter image, it enters a sleep state. In this case, the first meter image may be stored in the first section M1 of the memory 132 .

In addition, when the controller 131 wakes up at the second time and receives a connection signal through the transceiver 134 , the controller 131 measures it through the meter images and the thermometer stored in the memory 132 . send the temperature. In this case, the meter images are first to third meter images stored in the first to third sections M1 to M3, respectively. The second to third meter images will be described in more detail hereinafter.

In addition, in the case of the walking meter reading mode, the controller 131 wakes up at the third time and transmits a connectable notification signal to the outside, and when a connection signal is received from the meter reading unit terminal, stored in the memory 132 The meter images and the temperature measured through the thermometer may be transmitted to the meter reading source terminal. The meter images are first to third meter images stored in the first to third sections M1 to M3, respectively.

On the other hand, the control unit 131, which wakes up at the first time, if the day is not the meter reading day, drives the camera 110 to take a meter image, and as a second meter image, is further stored in the memory 132 . can be saved In more detail, the second meter image may be stored in the second section M2 of the memory 132 . The second meter image is an image for a welfare mode, such as a flow rate mode or an elderly living alone, indicating the use rate of water to be supplied.

At this time, the control unit 131 stores the second meter image in the memory 132, and after a predetermined time elapses (eg, 4 hours), restarts the camera 110 to activate the meter image, , as a third meter image, may be further stored in the memory 132 . That is, when the first time is a time when the user does not use water and the second meter image and the third meter image are changed, it may be considered that water leakage occurs.

Meanwhile, in the walking meter reading mode, the control unit 131 transmits the first to third meter images to the meter reading source terminal in the case of periodic meter reading, and drives the camera 110 when it is not in the periodic meter reading period. After taking a meter image, and storing it as a fourth meter image in the fourth section M4 of the memory 132, the first meter image, the fourth meter image, and the temperature measured through the thermometer are measured by the meter reading source can be sent to the terminal.

In one embodiment, the control unit 131 wakes up at the first time and checks whether the day is the meter reading day, and if it is not the meter reading day, when a connection signal is received within a predetermined time, the meter Images and temperature may be transmitted, and when a connection signal is not received within the predetermined time, the sleep state may be entered.

The control unit 131 corresponds to a part of the meter reading method according to the present invention. Hereinafter, the meter reading method according to the present invention will be described in more detail.

3 is a flowchart of a meter reading method according to an embodiment of the present invention, and FIG. 4 is a flowchart of the meter remote meter reading mode shown in FIG. 3 .

Referring to FIG. 3 , a remote meter reading method according to an exemplary embodiment of the present invention includes performing a remote meter reading mode ( S100 ) and a walking meter reading mode ( S200 ).

2 and 4 , in the remote meter reading mode, it is in the sleep state (S101) and enters the wake-up state at a first time every day (step S102). In more detail, when the first RTC 151 transmits a first time to the first control unit 131 , the meter remote meter reading device 100 enters a wake-up state. Accordingly, it is possible to reduce the consumption of the battery 160 compared to the case where the battery 160 is always driven. Meanwhile, the first time may be set arbitrarily, but may be set, for example, in a time zone in which water consumption is low in the consumer, that is, late at night.

Thereafter, the leak determination data converted into an electrical signal through the sound source measuring device 140 is stored in the fifth section M5 of the memory 132 , and the temperature measured through the thermometer 160 is the fifth of the memory 132 . It is stored in section M6 (step S103).

Thereafter, it is checked whether it is in the meter reading mode (S120), and in the case of the meter reading mode, it is checked whether the same day is the meter reading day (step S104). Here, the meter reading mode is a general consumer, and modes other than the meter reading mode will be described in more detail with reference to FIG. 5 .

If the check result day is the meter reading day, the camera 110 captures a meter image and stores it as a first meter image. In this case, the first meter image may be stored in the first section M1 of the memory 132 .

Thereafter, in order to reduce power consumption, it enters a sleep state (step S106).

In addition, if the same day is not the meter reading day, it immediately enters the sleep state without taking an image of the meter.

Thereafter, at the second time every day, the wake-up state is entered (step S107). In more detail, when the first RTC 151 transmits a second time to the first control unit 131 , the meter remote meter reading device 100 enters a wake-up state.

Thereafter, it is checked whether the same day is the meter reading period (step S108), and if it is the meter reading period, after waiting for the reception of a connection signal from the outside (step S109), when a connection signal is received from the outside (step S110), the meter images and temperature is transmitted (step S111). Here, the meter images are the first meter images of the first section M1 of the memory 132 . Also, at this time, the leak determination data of the fifth section M5 of the memory 132 may be transmitted together.

In this way, after the first meter image and water leak determination data are transmitted, it enters the sleep state (step S112). At this time, the first meter image and water leakage determination data may be entered into the sleep state immediately after transmission, but may enter the sleep state after a certain period of time (eg, 2 hours) has elapsed. Therefore, as a result of sending the first meter image and water leak determination data, if the reception is poor from the outside, a connection signal can be transmitted again from the outside, and accordingly, the first meter image and water leakage determination data can be transmitted again. .

On the other hand, in this remote meter reading method, in the remote meter reading mode, after waking up at the second time (step S107), it is checked whether the same day is the meter reading period (step S108). It is checked whether a signal is received (step S113), and if the connection signal is not received, it enters a sleep state (step S114), and when a connection signal is received, the first meter image, the temperature and the water leak Determination data can be transmitted (step S111). Therefore, it is possible to respond to irregular situations such as the moving of the consumer.

5 is a flowchart of a meter remote meter reading mode according to another embodiment of the present invention. The embodiment disclosed in FIG. 5 is substantially the same as the embodiment illustrated in FIG. 4 , except that the embodiment disclosed in FIG. 4 further includes a process of determining the meter reading mode and corresponding to the case in which the meter reading mode is not. Accordingly, overlapping descriptions are omitted.

2 and 5 , as a result of checking whether the meter reading mode is in the meter reading mode (step S104), if it is not in the meter reading mode, a meter image is photographed and stored as a second meter image (step S121). In this case, the second meter image may be stored in the second section M2 of the memory 132 .

Thereafter, it is checked whether it is in the flow rate mode (step S122). The water flow rate refers to the value obtained by dividing the amount of water collected as a fee (flow water) by the total amount of water produced and supplied (total water supply) at the water purification plant in percentage. This means less

As a result of the check, in the case of the flow rate mode, after a certain period of time has elapsed (eg, 4 hours, step S123), a meter image is photographed and stored as a third meter image (step S124). In this case, the third meter image may be stored in the third section M3 of the memory 132 . In this way, the amount of water leakage can be predicted through the difference between the images of the second and third meters, and this can be used as a data for managing the flow rate and responding to user complaints.

Thereafter, it is checked whether the same day is the meter reading day (step S125), if it is not the meter reading day, it enters the sleep state (step S106), and if it is the meter reading day, the second meter image is replaced with the first meter image (step S126) .

As a result of the flow rate mode check (step S122), if it is not in the flow rate mode (that is, in the case of welfare mode for caring for the elderly living alone), check whether the day of recognition is the meter reading day (step S125), and if it is not the meter reading day, sleep The state is entered (step S106), and when it is a meter reading day, the second meter image is replaced with the first meter image (step S126).

On the other hand, when transmitting the meter images and temperature in this embodiment, the first to third meter images and temperature are transmitted (step S111).

Referring to FIG. 6 , in the walking meter reading mode, it is in the sleep state (step S201) and enters the wake-up state at the third time every day (step S202). In more detail, when the second RTC 152 transmits a second time to the first control unit 131 , the meter remote meter reading device 100 enters a wake-up state. Here, the third time may be the first time in the middle of the night, whereas the third time may be during business hours, that is, within the working hours of the meter reading, for example, in the morning.

Thereafter, a connectable notification signal is transmitted to the outside (step S202), and the remote meter reading device notifies an external device, for example, a meter reading terminal, that the meter is in a state capable of receiving an external signal. For example, the connectable notification signal is repeatedly transmitted at regular intervals while waiting for the connection signal reception (step S204).

Thereafter, it is determined whether or not a connection signal is received from an external device (step S205), and if the connection signal is not received within a predetermined time, it enters a sleep state (step S209), and when the connection signal is received, regular It is checked whether it is a meter reading (step S206).

As a result of the check, in the case of periodic punctuation, the stage of transmitting meter images and temperature is entered. At this time, the meter images stored in the first to third sections (M1, M2, M3) of the memory 132 may be the first to third meter images, and the leak determination data stored in the fifth section (M5) can also be transmitted. have.

As a result of the check, if it is not the periodic meter reading, a meter image is taken and stored as a fourth meter image (step S210). In this case, the fourth meter image may be stored in the fourth section M4 of the memory 132 . Therefore, when the consumer moves, the meter inspector directly visits and it is possible to accurately measure at the time of moving.

Thereafter, the first meter image and the fourth meter image are transmitted to the meter reading device terminal (step S211). When the meter images are transmitted, the leak determination data stored in the fifth section M5 of the memory 132 may be transmitted together.
