Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic meter reading device for automatically metering the amount of electric power used by a consumer.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing a conventional automatic meter-reading device for measuring the amount of electric power used. In the figure, 1 is a metering unit which is installed in each consumer and which outputs a respective amount of electric power used, and is a metering means consisting of a plurality of meters 1a (M _{1 to} M _n ). A central device 3 for collecting and managing electric energy at a predetermined date, a terminal device 3 installed between the transmitting unit 1 and the central device 2, an input interface 4, a memory 5 for storing data, and a display unit for displaying data. 6 and a control unit 8 for reading these data signals, processing the data, and transmitting the data to the central unit 2 from the transmission / reception circuit 7. 9 is a transmitter 1 and an input interface 4
Is a transmission line that connects the central unit 2 and the transmission / reception circuit 6.

Next, the operation will be described. The central unit 2 outputs a selection signal for reading the data of the meter 1a (M ₁ ) to the terminal unit 3 via the transmission line 10 in order to collect the meter reading (measurement) value. When the terminal device 3 receives the selection signal, the terminal device 3 transmits the meter reading data via the transmission line 9 to the meter 1a (M ₁ ) to collect the meter reading data, and then sends the data to the central unit 2 via the transmission line 10. Similar processing is performed for other meters 1a
(M _{2 to} M _n ) is also performed, and data of all meters is collected. Further, by manually operating the display unit 6 as needed, the meter reading data can be displayed on the display unit 6 by performing transmission with the meter 1a (M _n ).

[0004]

Since the conventional automatic meter reading device is constructed as described above, there is no means for confirming whether the meter reading value is normal in the central device. In addition, there is a problem that the date and time when the meter reading is performed and the meter reading value cannot be confirmed from the central device at the terminal of the terminal device.

The present invention has been made in order to solve the above problems and provides an automatic meter reading device capable of confirming the normality of a meter reading value in a central device and confirming a meter reading date and time and a meter reading value in a terminal device. The purpose is to

[0006]

SUMMARY OF THE INVENTION An automatic meter reading device according to the present invention is a metering unit for measuring each usage of a plurality of consumers, and a cumulative value obtained by accumulating each usage measured by this metering unit. In the terminal device that displays the and the central device that collects each usage amount accumulated in the terminal device at each predetermined date, a means for storing and displaying the date and time of the collection and the measured value is provided in the terminal device. It is provided.

[0007]

In the automatic meter-reading device according to the present invention, the display unit displays the measured value and the measured date and time, and the current usage amount can be confirmed on the terminal device.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a block diagram showing an automatic meter-reading device according to a first embodiment of the present invention. In the figure, 1 and 2 are the same as the conventional one, and the explanation thereof is omitted. A terminal device 11 is arranged between the transmitter 1 and the central device 2 and has the following components. Reference numeral 12 is an input interface that is connected to the transmission line 9 and receives a signal from the transmission unit 1 received via the transmission line 9. Reference numeral 14 is a signal of the input interface 12 and performs other data processing necessary for transmission and display. A control unit for transmitting from the transmission / reception circuit 13 to the central unit 2 via the transmission line 10, 15 is a clock circuit for notifying the current date and time to the control unit 14, and 16 is data necessary for the operation of the control unit 14 and is transmitted to the central unit 2. A memory for storing the meter reading (measurement) value and the date and time, and a display unit 17 connected to the control unit 14 for displaying the input / output state of the data, the meter reading value and the date and time. In addition,
The display of the meter reading value and its date and time is performed by the operations of 14 to 17, which is indicated by the displaying means 18.

Next, the operation will be described. The central unit 2 uses the transmission line 10 to collect the meter reading value of the meter 1a (M _n ).
A selection signal is output to the terminal device 11 via. When the terminal device 11 receives the selection signal, the terminal device 11 transmits the data via the meter 1a (M _n ) corresponding to the selection signal and the transmission line 9 to collect the meter reading value. Next, the current date and time and the meter reading value are stored in a memory and then sent to the central unit 2 via the transmission line 10. The terminal device 11 displays the accumulated value up to the present, the meter reading value sent to the central device 2, and the date and time thereof on the display unit 17. In this case, the cumulative value is transmitted and updated with the transmitter 1 at a constant cycle,
The meter reading value and its date and time do not change until the next call command of the central unit 2 is issued. The current usage amount from the previous meter reading date can be known from the displayed cumulative value and meter reading value.

[0010]

As described above, according to the present invention, the measuring means for measuring the respective usage amounts of a plurality of consumers, and the respective usage amounts measured by the measuring means are accumulated and the accumulated value is displayed. In a terminal device and a central device that collects each usage amount accumulated in the terminal device at a predetermined date, the terminal device is provided with means for storing and displaying the date and time of collection and the measured value. There is an effect of being able to obtain an automatic meter-reading device capable of confirming the weighing value and the weighing date and time at the terminal unit and checking the current usage amount by comparing with the accumulated value.
