JPH05233992A - Method for imparting identifier for automatic meter inspection system - Google Patents

Abstract

PURPOSE:To eliminate the erroneous ID input for a radio slave set and also to simplify an input operation in the automatic meter inspection system partly adopting the radio system. CONSTITUTION:An ID memory 8 is incorporated in a radio slave set 6. An ID transmission circuit is incorporated in a meter 7 for automatic meter inspection. In the electrical connection, the ID set for the meter 7 from the ID transmission circuit is automatically inputted to an ID memory 8 on the radio slave set. Thus, the ID is automatically inputted, resulting in preventing an erroneous input and eliminating the ID input operation.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal network control device and an automatic meter-reading meter in a system for automatically measuring meters of gas, electricity, water, etc. installed in each customer by using a public telephone line. The present invention relates to an identifier assigning method in an automatic meter reading system in which wireless devices are attached to each other and wireless communication is performed between a terminal network control device and an automatic meter reading meter.

[0002]

2. Description of the Related Art In an automatic meter reading system, it is necessary to give an identifier (ID) to each meter, and this identifier is used when calling the meter for automatic meter reading from the center and transmitting information. To be done. Therefore, conventionally, individual identifiers are recorded in a circuit in the meter for automatic meter reading by using an identifier setter, and the assignment of this identifier is performed by attaching a wireless slave device to the meter for automatic meter reading. In this case, it is necessary to input the meter identifier for this wireless slave device. As this means, the identifier of the meter for automatic meter reading is visually read, and this is input to the wireless slave device using the setting device.

[0003]

For this reason, it is necessary to carry out the input work using the identifier setting device each time when the installation work of the wireless slave device is carried out on the meter for automatic meter reading, which is troublesome and erroneous. It may occur.

An object of the present invention is to provide a method of assigning an identifier to a wireless slave device which is easy to input and does not cause an input error.

[0005]

The constitution of the present invention is as follows.

[0006] In an automatic meter reading system in which a wireless master unit with a transmission / reception circuit is installed under a terminal network control device, and a wireless slave unit with a transmission / reception circuit is installed on the meter side for automatic meter reading, the meter is attached to the meter for automatic meter reading. The identifier transmission circuit for transmitting the generated identifier is incorporated in the meter side for automatic meter reading and the identifier memory circuit is incorporated in the wireless slave unit side, and when the wireless slave unit and the meter for automatic meter reading are electrically connected, the identifier transmitting circuit An identifier assigning method in an automatic meter reading system in which an identifier signal is transmitted from an identifier to a memory circuit and stored.

[0007]

In the meter for automatic meter reading, the identifier (usually the meter number) is input in advance, and the wireless slave device for the meter is not input. Therefore, when the meter for automatic meter reading and the wireless slave device are electrically connected, the identifier assigned to the meter for automatic meter reading is automatically transmitted from the transmission circuit to the wireless slave device, and this signal, that is, the identifier is the wireless slave device. It is input into the identifier memory circuit on the machine side. As a result, the wireless slave device can identify the signal from the wireless master device, drive the wireless slave device when it determines that it is self, and transmit the meter information to the wireless master device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic diagram of an automatic meter reading system adopting a partial wireless system in which the present invention is implemented. 1 is a center, 2 is a public telephone line, 3 is a consumer, 4 is a terminal network control unit (hereinafter referred to as "T-NCU"), 5 is a wireless master unit attached to the T-NCU 4, and 6 is a meter for automatic meter reading. The wireless slave device attached to 7 drives the wireless master device 5 from the center 1 via the public telephone line 2 and wirelessly calls the meter 7 for automatic meter reading. When this call is made, the information of the meter 7 for automatic meter reading is transmitted in the order of wireless slave device 6 → wireless master device 5 → public telephone line 2 → center 1.

FIG. 2 illustrates the embodiment in more detail. An identifier (hereinafter referred to as "ID") memory 8 and a CPU 9 are incorporated in the wireless slave device 6, and a memory is provided on the automatic meter reading meter 7 side. 10 and the CPU 11 are built in, and when the wireless slave device 6 is electrically connected to the automatic meter-reading meter 7, the activation message is input from the wireless slave device 6 to the CPU 11 in the automatic meter-reading meter 7, and then the CPU 11 side. ID of meter 7 for automatic meter reading recorded in memory 10
Is automatically input to the memory 8 on the wireless slave device 6 side. FIG. 3 is an explanatory diagram of communication between the wireless slave device 6 and the meter 7 for automatic meter reading.

[0010]

As described above, according to the present invention, when the ID transmitter circuit is incorporated in the automatic meter reading meter side and the wireless slave device is electrically connected to the automatic meter reading meter, the ID is automatically transferred to the wireless slave device side. Will be memorized. As a result, there is no concern that an input error will occur and there is no need to perform any ID input work.
