Description

  The present invention relates to an electric meter indication number display system using a smart meter.

  Conventionally, each home is provided with an electric meter for measuring the amount of electricity used, and a meter reader goes around each home and acquires the number of instructions displayed on the electric meter. Then, the number of instructions is totaled for each household in the electric power company, and the electricity bill is calculated based on the number of instructions.

  By the way, since electricity is indispensable to life in each home, the number of instructions of the electric meter is often changing. However, the fact that the number of indications on the electric meter does not change or the change is slow leads to providing information that it is an absence home to the outside. For this reason, the indication number of the electric meter may be used for crimes such as illegal intrusion and theft.

  Therefore, conventionally, a technique described in Patent Document 1 has been proposed. According to Patent Document 1, a third party cannot view the meter display without permission by providing a protective device that conceals and releases the concealment of the indication number display of the electric meter that measures power consumption using the blind. The technology is disclosed.

However, in the case of Patent Document 1, since the meter reader needs to operate the protective device every time he / she goes around the home, the work load on the meter reader increases.
Furthermore, checking the number of instructions of the electric meter on the electric power company side may be performed in addition to the above-described meter reading by the meter reader. For example, a worker dispatched to a contract abolishment or construction at the start of use confirms the number of instructions of the electric meter and acquires the number of instructions at the time of abolition or start. Even in such a case, since the worker needs to operate the protective device, the work load on the worker increases.

JP 2007-225452 A

  By the way, in recent years, an electric power network called a smart grid that automatically adjusts electric power supply and demand has been constructed using an electric meter called a smart meter. The smart meter has a communication function. By introducing the smart meter, bidirectional communication is possible between the electric power company and the electric meter, and between the electric meter and the home computer. As a result, data such as the amount of power used is automatically transmitted from the smart meter to the power company, and it is not necessary for the meter reader to visit in the home where the smart meter is introduced.

  Here, in the current smart meter, since the number of instructions is always displayed, it is possible for a third party to see the meter display, and the number of instructions of the smart meter is used to determine whether or not you are away. There is a risk of being. In this case, it is possible to prevent a third party from seeing the meter display without permission by providing the protection device of Patent Document 1 in the electricity consumption display section of the smart meter.

  However, when the smart meter is introduced, the opportunity for the meter reader to visit the home is reduced, but the opportunity for the construction worker to visually check the indicated value of the smart meter still remains. For this reason, when a device such as the protection device of Patent Document 1 is installed in the smart meter, the worker may not be able to confirm the number of instructions of the smart meter.

  Here, since the meter display of the smart meter is an electrical display, it is conceivable to provide a switch so as to electrically switch the meter display to non-display. However, in this case, it is necessary to devise measures to prevent a third party from operating the switch. For this reason, when the contract is abolished or the construction is started, the worker switches the non-display state to the display state if the meter display of the smart meter is hidden when visually checking the number of instructions of the smart meter. Some work is required, and the work load on the worker increases.

  The present invention solves such problems and shortens the time for displaying the number of indications in the smart meter to be constructed, thereby reducing the chance that the meter display is viewed by a third party. An object of the present invention is to provide an electric meter indication number display system.

Thus, it is possible to provide an electric meter indication number display system that realizes a reduction in the chance that the meter display is visually recognized by a third party.

It is explanatory drawing which shows the structure of the electric meter instruction | indication number display system in one Embodiment of this invention. It is explanatory drawing which shows an example of construction schedule information.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory diagram showing a configuration of an electric meter instruction number display system according to an embodiment of the present invention.
The electric meter indication number display system 1 includes a management device 10 corresponding to a power company management device, a host terminal 12, a storage device 14 storing construction schedule information, a smart meter 20 on the customer's house side, and a customer management device. A corresponding management device 30 and a network 50 are included.

  The management device 10 is a device called MDMS, and collects and analyzes information transmitted from the smart meter 20 in each household, for example, the number of instructions, sets a power charge, monitors power outage / recovery, etc. The smart meter 20 has functions such as remote control.

The host terminal 12 can transmit to and receive from the management apparatus 10 and sends various command signals to the management apparatus 10.
The storage device 14 stores various programs to be executed by the host terminal 12 and construction schedule information. The construction schedule information stored in the storage device 14 can be acquired by the host terminal 12.
The smart meter 20 is a watt hour meter that is installed in a customer's house and measures the amount of power used, digitally measures the amount of power used, and increases the number of instructions according to the amount of power used. A display control unit 20b to be displayed on the display unit 20a and a communication control unit 20c for automatically transmitting the number of instructions to a power company or the like every predetermined time are provided.

  The management device 30 is a device called MDMS, similar to the management device 10, and is installed in a customer's house, and includes an information display unit 30a and an input unit 30b that performs various inputs by customer operations. . Further, the management device 30 aggregates the amount of power used and displays the graph on the information display unit 30a, or displays a power failure information, a power charge, etc. on the information display unit 30a, or transmits an instruction signal to the smart meter 20. It has functions.

  The network 50 is a power network capable of information communication called a smart grid.

  Further, as shown in FIG. 1, the management device 10 and the smart meter 20 are connected to be able to transmit and receive via a network 50, and the smart meter 20 and the management device 30 can be transmitted and received indoors by wire or wirelessly. It is connected.

  As described above, both the management device 10 and the management device 30 are capable of bidirectional communication with the smart meter 20.

  In the electric meter instruction number display system 1 of the present embodiment, the instruction number is automatically transmitted from the smart meter 20 to the management device 10 and the management device 30 every 30 minutes, for example. As an instruction signal transmitted from the management device 10 and the management device 30 to the smart meter 20, for example, an instruction number display request signal for requesting the instruction number display unit 20a to be in a display state and the instruction number display unit 20a are not displayed. An instruction number non-display request signal for requesting a state is given.

  When the indication number display request signal and the indication number non-display request signal are transmitted from the management device 10 or the management device 30 to the smart meter 20, the display control unit 20b responds to the indication number display request signal and the indication number non-display request signal. Thus, the instruction number display unit 20a is controlled so as to switch between a state in which the instruction number is displayed on the instruction number display unit 20a and a state in which the instruction number is not displayed. That is, according to the electric meter instruction number display system 1 of the present embodiment, the instruction number display unit 20a is arbitrarily instructed by an instruction number display request signal and an instruction number non-display request signal from either the power company side or the customer side. It is possible to switch between a number display state and a non-display state.

  Note that the non-display state may be a display mode in which the number of instructions is not displayed. For example, the current supplied to the instruction number display unit 20a is cut off. Only the backlight is lit without displaying the number of instructions. Or a state where an image different from the number of instructions is displayed may be set as a non-display state.

  In addition, the storage device 14 causes the management device 10 to output an instruction number display request signal to display the instruction number display unit 20a before the construction worker arrives at the site based on the construction schedule information. A construction support program is stored. The host terminal 12 controls the management apparatus 10 to output an instruction number display request signal at a predetermined timing based on the construction schedule information by executing the construction support program.

FIG. 2 is an explanatory diagram illustrating an example of construction schedule information stored in the storage device 14.
The construction schedule information is information obtained by associating work (construction) order, information for identifying a construction destination such as a customer name, an address, and a customer number, an instrument number, construction contents, and a construction state.

In the construction schedule information, the order of work (construction), customer name, address, customer number, instrument number, and construction content are input in advance in a format for creating construction schedule information before the construction schedule date.
The construction status is updated by the processing of the host terminal 12 when a construction completion report is received from an on-site worker. Specifically, when a construction completion notification is received from an on-site worker, the construction status in the corresponding work order is updated to “construction completed” by the operation of the operator who has received the construction completion notification, for example. . When the construction status is updated to “construction completed”, the construction status of the next work order is automatically updated from “standby” to “under construction”. Note that “standby” is input to the construction status of the work order that has not reached in turn.

Next, the construction flow based on the construction schedule information will be described.
First, before moving to the first construction destination in the construction described in the construction schedule information, the construction worker informs the operator of the power company that construction is to be started. The operator who has received the notification operates the host terminal 12 to execute the construction support program.

  The host terminal 12 that has executed the construction support program updates the construction status of the first customer to “under construction” in the construction schedule information. Here, the host terminal 12 estimates the time until the worker arrives at the customer's building updated to “under construction”, and sets a set time slightly earlier than the calculated value in the timer. Then, the host terminal 12 transmits a command signal to the management apparatus 10 when the timer counts the set time, and causes the management apparatus 10 to output an instruction number display request signal.

  Thereby, when the worker arrives at the building of the first customer, the indication number display portion 20a of the smart meter 20 of the first customer is in the display state. Then, the worker visually recognizes the number of instructions displayed on the instruction number display unit 20a, and after performing recording, executes the construction.

  After the construction is completed, the worker operates the portable terminal carried by the worker to notify the operator of the power company that the work is completed, and then moves to the next construction site. The operator who has received the notification operates the host terminal 12 to update the construction state of the first customer to construction completion. The host terminal 12 automatically switches the construction state of the next customer to “under construction” when “construction completion” is input to the construction schedule information, and further, from the first customer building to the next customer building. The travel time required until the time is calculated, and a set time slightly earlier than the calculated value is set in the timer. Then, the host terminal 12 transmits a command signal to the management apparatus 10 when the timer counts the set time, and causes the management apparatus 10 to output an instruction number display request signal. Thereby, when the worker arrives at the building of the next customer, the indication number display part 20a of the smart meter 20 of the next customer is in the display state.

  Hereinafter, the worker operates the mobile terminal every time construction is completed and informs the operator of the power company that the work has been completed. The indication number display part 20a of the customer's smart meter 20 enters the display state.

  If the worker's portable terminal can access the storage device 14 and the worker can update the construction status column of the construction schedule information by operating the portable terminal, the operator of the power company It becomes possible to omit the trouble of contacting the.

  As described above, according to the present embodiment configured as described above, for example, when it is necessary to directly check the number of instructions of the smart meter 20 on the power company side, such as abolition of a contract or construction at the start of use. When the construction worker arrives at the customer's building for the construction, the number of instructions of the smart meter 20 can be displayed. Thereby, the worker can easily confirm the number of instructions of the smart meter 20, and can start the construction smoothly. In addition, since it is possible to shorten the time for displaying the number of instructions of the smart meter, it is possible to reduce the chance that the meter display is visually recognized by a third party.

  Further, according to the present embodiment, when a display / non-display instruction signal is received from a customer terminal, the instruction number display in the instruction number display unit 20a is displayed in either the display state or the non-display state according to the instruction signal. Therefore, when the customer wants to see the display of the smart meter 20 directly, the display state can be set, and the rest can be hidden. Thereby, it becomes possible to reduce the chance that the meter display is visually recognized by a third party. In addition, since the time for displaying the number of instructions on the smart meter can be further shortened, the opportunity for the third party to visually recognize the number of instructions can be reduced.

  Further, according to the present embodiment, the number of instructions of the smart meter 20 can be displayed when the worker arrives at the building of the customer who performs the construction. Thereby, the worker can easily confirm the number of instructions of the smart meter 20, and can start the construction smoothly. Moreover, since the time for displaying the number of instructions in the smart meter 20 can be further shortened, it is possible to reduce the chance that the number of instructions is visually recognized by a third party.
