DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automatic communication system in which a management center and a wireless master unit are connected by a telephone line and a wireless slave unit is attached to a managed terminal such as a gas meter, an electric meter, a water meter, or a vending machine. The present invention relates to a wireless handset registration method in a meter reading or management system.

[0002]

2. Description of the Related Art When a new slave unit is registered to a master unit, the operation mode of both the master unit and the slave unit is set to a slave unit setting mode by pressing a setting button or the like, and then the ID is manually or automatically set. The registration of the slave unit is performed by exchanging registration messages and the like.

[0003]

Therefore, there are the following disadvantages. a. Simultaneously operating the setting buttons of the master unit and the slave unit at the time of registration of the slave unit is troublesome because the master unit may be located at a remote place. b. In the case of a master unit connected to multiple slave units, normal communication cannot be received from another slave unit during the slave unit setting mode. For this reason, it is necessary to manually switch the mode of the master unit, and the normal communication waiting time is prolonged accordingly. c. In the case of the conventional example, since the relationship between the wireless master device and the slave device is determined in advance regardless of the installation environment, etc., the wireless master device and the slave device having the best communication state are not necessarily registered as a pair. Absent. Therefore, a communication failure is likely to occur.

[0004]

Means for solving the above problems are as follows. In a wireless base station attached to a public telephone line terminal and a wireless communication system configured to transmit information of a management terminal device to the wireless base station via a wireless client, The wireless master unit owns the connected telephone number, and the wireless master unit is normally in a standby state for wireless communication and slave unit registration communication except when the wireless master unit is in communication. At the same time as the handset registration mode, a handset registration request is sent to the wireless base unit, and the base unit that has received the handset registration request from the base unit has its own delay time that is proportional to the reciprocal of the radio wave intensity. A response having the ID as data is returned to the slave unit, and the slave unit exchanges a message for registration as a slave unit with the master unit that has returned the response earlier within the specified time, and responds within the specified time. If it is not obtained, it will be fixed as registration failure After a short while, the master unit completes registration of the slave unit, notifies the management center of the ID transmitted from the slave unit and its own telephone number, and performs registration of the slave unit setting, and the management center is sent from the master unit. Wireless terminal registration method for performing a center polling communication test on the terminal device side based on the telephone number and the ID, and confirming the registration success.

[0005]

When registering a wireless slave device (terminal device), a registration request such as an ID is first sent from the terminal device to the slave device.
The slave unit, upon receiving this request, requests the wireless master unit for registration of the slave unit, and performs setting registration communication with the master unit that responded the earliest, and when this is completed, the master unit calls the management center. , The ID of the newly registered terminal device
Register with D at the management center. The Administration Center
When the registration is completed, the terminal device is called by the management center polling to check the connection. In the above-mentioned registration, if there are a plurality of master units that have received a slave unit registration request from the slave unit, the master unit that has received the request has a relationship proportional to the reciprocal of the radio wave intensity (reception electric field intensity). The own ID is returned to the slave unit with the delay time, and the earlier one is linked.

FIG. 1 is an explanatory view of an automatic gas meter reading system embodying the present invention. 1 is a management center, 1a is a file, 2 is a telephone line, 3, 3a is a T-NCU, 4, 4a
Is a wireless master unit branched from the T-NCU 3, 5 is a wireless slave unit, 6 is an automatic meter reading gas meter connected to the wireless slave unit 5 by wire. In the case of the embodiment, the automatic meter reading meter 6 Then, the wireless slave device 5 and the wireless master device 4 are activated and, for example, the flow rate information in the automatic meter reading meter 6 is read from the wireless slave device 5 to the wireless master device 4.
→ Telephone line 2 → Management center 1

[0007] The radio cell station 4 has a telephone number to which it is connected in a memory, and the radio cell station 4 is normally in a standby state for radio communication and slave unit registration communication except when it is communicating. The wireless handset 5 enters a handset registration mode upon receiving a terminal call from the automatic meter reading gas meter 6, issues a handset registration request to the wireless base unit 4 or 4 a, and sets the handset 6 and the base unit 4.
Or, 4a returns a response having its own ID (parent device) as data with a delay time having a relationship proportional to the reciprocal of the radio wave intensity to the child device 5, and the child device 5 has the best communication environment in the parent device 4 or 4a. A message for registration is exchanged between the server and the server. If no response is obtained within the specified time, the registration is retried after a certain period of time. The master unit 4 or 4a, which has completed the registration of the slave unit 5, notifies the management center 1 of the ID, the meter company number, and the telephone number of the master unit transmitted from the slave unit 5, and registers the slave unit. The management center 1 is the parent machine 4 or 4a
A center polling communication test is performed using the telephone number, ID, and meter company number sent from the company to confirm registration success. FIG. 2 shows a flow of the registration work.

[0008]

According to the present invention, the following effects can be obtained by registering a wireless slave unit by the above method. a. Registration of the wireless master device can be performed by operating only the wireless slave device. b. A wireless slave unit can be registered for the wireless master unit with the best communication environment. c. It is possible to easily and efficiently perform registration management of the wireless client device and the terminal device in the management center. d. After the registration of the wireless master unit and the slave unit, the communication test performed on the management center side has the best communication condition between the wireless master unit and the slave unit, so there is no communication error, and the work of the communication test is streamlined. Can be.
