Abstract

PURPOSE:To obtain a metering value of metering devices on all floors by one master set. CONSTITUTION:A master radio equipment (master set) 13 is installed in an elevator 7 of a multiple housing 1. The master set 13 is connected to a metering center via a public line. Slave radio sets (slave sets) 6a, 6b,... are connected to metering devices 5a, 5b,... of rooms 3a, 3b,... of each floor and radio communication is made between the master set 13 and a slave set 6 of a floor when the elevator 7 is stopped at the floor and a metering value of each metering device 5 of the floor is sent to a metering center via the master set 13. When the elevator 7 is stopped to another floor, the metering value of the metering device 5 of the floor is sent to the metering center similarly. Thus, the metering values of all the metering devices 5 are sent to the metering center by stopping the elevator 7 to all the floors of the multiple housing 1 and making radio communication between the master set 13 and the slave sets 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication system for transmitting information such as gas meter, electric power, water meter and the like to a center in an apartment house or the like.

[0002]

2. Description of the Related Art Recently, in a multi-family house or the like, a master wireless device (master device) connected to a center via a communication line is installed on one floor, and slave wireless devices (slave devices) are respectively installed in a plurality of meter reading devices. ) Is connected, and wireless communication is performed between the master unit and the slave unit, thereby sending a meter reading value to the center via the slave unit and the master unit.

[0003]

However, in such a system, for example, when a master unit is installed on the first floor,
Since radio waves are weak, communication cannot be performed with a slave unit located on a distant floor such as the tenth floor, and a meter reading cannot be obtained.

[0004] For this reason, it is conceivable to increase the transmission output. However, the battery consumption becomes severe, and there is a legal restriction on the radio wave output. It is also conceivable to install a master unit on each floor, but there is a problem that the cost is high.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a single dwelling unit such as a high-rise dwelling unit with only one base unit provided for all floor units. To provide a wireless communication system capable of obtaining such information.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a wireless communication system for performing wireless communication in a building having a plurality of target devices on each of a plurality of floors, provided in an elevator. A master unit connected to a center via a communication line, and a slave unit connected to each of the target devices, respectively, between the master unit and each slave unit while raising and lowering the elevator. And transmitting information on the target device to the center.

[0007]

According to the present invention, communication between the master unit and each slave unit is performed while raising and lowering the elevator, and information on the target device is sent to the center.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic diagram of an apartment house 1 using a wireless meter reading system as an example of a wireless communication system according to one embodiment of the present invention. Apartment 1 is 10
It is a multi-storey high-rise building, and each room (one home) 3a, 3
b,... are provided with gas metering devices 5a, 5b,. Each meter reading device 5a, 5
b are connected to child wireless devices (child devices) 6a, 6b,... Reference numeral 7 denotes an elevator.
Is provided.

FIG. 2 is a schematic configuration diagram of the wireless meter reading system. The wireless meter reading system includes a meter reading device 5a, 5b,
..., slave units 6a, 6b, ..., elevator control device 9,
Master device controller 11, master device 13, network control device (NC
U) 15 and a meter reading center 19.

An elevator control device 9 controls the elevator 7. The master unit controller 11 controls the master unit 13, and for example, all the slave units 6a, 6b,
.., Etc. can be printed. Master unit 13 is provided in elevator 7,
Electric power is supplied from a lighting power supply in the elevator. Base unit 13 is connected to NCU 15 via an emergency telephone line. The NCU 15 is connected to the meter reading center 19 via the public line 17.
Connected to. The slave units 6a, 6b,... Are respectively attached to the meter reading devices 5a, 5b,.
Wireless communication is performed between 6b,...

Next, the procedure of the meter reading in this embodiment will be described. In the state shown in FIG. 1, the elevator 7 is stopped on the seventh floor. In this state, the master unit 13 and the slave units 6a, 6
b,... are communicated, and the meter reading devices 5a, 5b,.
Are sent to the meter reading center 19 via the master unit 13 and the NCU 15.

When the elevator 7 moves to another floor, the meter reading value of the meter reading device 5 on this floor is sent to the meter reading center 19 according to the same procedure as described above. Thereafter, similarly, the elevator 7 is stopped on each floor, and the meter reading value of the meter reading device 5 on that floor is sent to the meter reading center 19, so that the meter reading center 19 reads the meter reading values of all the meter reading devices of the apartment house 1. Obtainable.

When reading the meter, the elevator should be used at night or the like.
This can be done while stopping the floor 7 on each floor. Further, in the above-described embodiment, a gas meter reading device has been described. However, the present invention is also applied to a meter reading system such as electric power and water supply. In addition, office buildings with copy machines on each floor,
The present invention can be widely applied to the case where information such as the number of copies used is sent to the center, or the case where information such as the number of remaining soft drinks is sent to the center in a building or the like having a vending machine on each floor. Can be done.

[0014]

As described above in detail, according to the present invention, information of target devices on all floors can be obtained by one master unit.
