Monitoring device and monitoring method

Abstract

To provide a monitoring device to accurately calculate a use amount in the case of calculating the use amount on the basis of a lifetime value, even when replacement work of a meter during a target period is carried out; and to provide a monitoring method.SOLUTION: In a monitoring system having one or more reading meters, one or more controllers, one or more sub controllers and a monitoring device, a monitoring device 3 comprises: an acquisition part 302 that acquires a read value by the reading meter to be monitored; a lifetime value calculation part 303 that calculates a lifetime value by adding an increase amount of a current read value acquired by the acquisition part from a previous read value acquired by the acquisition part; and an instruction receiving part 306 that receives, by reading meter, a first instruction indicating replacement start or a second instruction indication replacement completion. The lifetime value calculation part, if the first instruction to the reading meter is received by the instruction receiving part, does not carry out addition to the lifetime value to the reading meter during a period until the second instruction to the reading meter is received.SELECTED DRAWING: Figure 2

Claims

1. an acquisition unit that acquires the readings of a meter to be monitored; a lifetime value calculation unit that calculates a lifetime value by adding an increase in the current reading value acquired by the acquisition unit from a previous reading value acquired by the acquisition unit; an instruction receiving unit that receives, for each meter, a first instruction indicating a start of replacement or a second instruction indicating an end of replacement; a pre-replacement reading acquisition unit that, when a first instruction for the meter is accepted by the instruction acceptance unit, acquires a reading of the meter at the time the first instruction is accepted as a pre-replacement reading; a replacement date acquisition unit that, when a first instruction for the meter is accepted by the instruction acceptance unit, acquires a date on which the first instruction is accepted as a replacement date of the meter; a post-replacement reading value acquisition unit that, when a second instruction for the meter is accepted by the instruction acceptance unit, acquires a reading value of the meter at the time the second instruction is accepted as a post-replacement reading value; When a first instruction for a meter is received by the instruction receiving unit, the lifetime value calculation unit does not add to the lifetime value for the meter until a second instruction for the meter is received. A monitoring device comprising:

2. A pre-replacement reading value acquired by the pre-replacement reading value acquisition unit; The replacement date of the meter acquired by the replacement date acquisition unit; and 2. The monitoring device according to claim 1, further comprising a display control unit that displays on a display unit a screen showing the post-replacement reading value acquired by the post-replacement reading value acquisition unit.

3. the display control unit causes a check box for receiving a first instruction or a second instruction to be displayed on the screen; The instruction receiving unit is accepting a first instruction when a check box displayed on the screen is checked; 3. The monitoring device according to claim 2, wherein a second instruction is accepted when a check box displayed on the screen is changed from on to off.

4. The replacement date acquisition unit, When a second instruction for the meter is received by the instruction receiving unit, a date on which the second instruction is received is obtained; A monitoring device as described in any one of claims 1 to 3, characterized in that if the date on which the second instruction was received is different from the date on which the first instruction was received, acquired by the replacement date acquisition unit, the date on which the second instruction was received is acquired as the replacement date of the meter.

5. The instruction receiving unit sets a replacement mode of the meter to be valid when a first instruction for the meter is received, 5. The monitoring device according to claim 1, wherein, when a second instruction for the meter is received, a replacement mode of the meter is changed from enabled to disabled.

6. A monitoring method using a monitoring device, comprising: An acquisition unit acquires a reading of a meter to be monitored; A lifetime value calculation unit calculates a lifetime value by adding an increase in the current reading value acquired by the acquisition unit from a previous reading value acquired by the acquisition unit; an instruction receiving unit receiving, for each meter, a first instruction indicating the start of replacement or a second instruction indicating the end of replacement; a pre-replacement reading acquisition unit acquiring, when a first instruction for the meter is accepted by the instruction acceptance unit, a reading of the meter at the time the first instruction is accepted as a pre-replacement reading; a replacement date acquiring unit acquiring, when a first instruction for the meter is accepted by the instruction accepting unit, a date on which the first instruction is accepted as a replacement date of the meter; a step in which, when a second instruction for the meter is received by the instruction receiving unit, a post-replacement reading value acquisition unit acquires, as a post-replacement reading value, a reading value of the meter at the time when the second instruction is received, When a first instruction for a meter is received by the instruction receiving unit, the lifetime value calculation unit does not add to the lifetime value for the meter until a second instruction for the meter is received. A monitoring method comprising:
