DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a remote terminal (monitoring center) for connecting a first terminal such as a weighing device such as a gas meter, a water meter, an alarm or a security device, and for example, a gas supply company or a security company. And a terminal network controller for relaying communication between a remote terminal and a first terminal by connecting to a remote terminal and performing automatic remote meter reading from the remote terminal and notification of gas leak from the terminal to the remote terminal. In particular, the present invention relates to a terminal network control device installed indoors.

[0002]

2. Description of the Related Art A current terminal network control device employs means for connecting to a first terminal by a metal cable. The first terminal is installed outdoors in the case of a gas meter or a water meter. Therefore, a means for installing the terminal network control device outdoors has been adopted because of the ease of connection work and maintenance with the first terminal. Normally, a communication line is connected to a telephone or facsimile installed indoors through a protector installed at a high position on an outer wall surface of a house. The terminal network controller is connected between the protector and the entrance to the house, and is usually fixed to the wall surface adjacent to the protector.
Both the means for connecting the communication line to the terminal network control device and the means for connecting to the lead-in line indoors are installed outdoors for long periods of time and exposed to the wind and rain. ing. Therefore, these constructions require the qualification of a construction supervisor. The terminal network controller is
It is configured to be powered by a battery so that power supply work is not required. The battery is not easily replaced because it is installed on the outer wall of a high place. Therefore, the design is based on the premise that there is only communication for an emergency call or meter reading about once a month, and cannot be used for multipurpose communication. FIG. 15 shows how such a terminal network control device is installed.

[0003] The terminal network control device 1, the remote terminal 102, the second
The relationship with the terminal 103 (telephone) will be described. For example, the gas meter, which is one of the first terminals 100, determines that gas is leaking and issues an alarm when gas flows for a predetermined time or more. The alarm is reported to the remote terminal 102 via the terminal network control device 1. In the notification, information indicating which terminal network control device 1 has issued the notification is set. The clerk of the remote terminal 102 recognizes the telephone number or the like of the contact using the information displayed on the screen of the CRT or the like or the printing device. Subsequently, the staff at the remote terminal 102
In reality, the telephone on the remote terminal 102 side calls the telephone 103 on the terminal network control device 1 in order to confirm the actual state of the gas usage, and takes measures according to the state.

As described above, the telephone 103 operates independently of the terminal network control device 1 even though it is connected to the same communication line. The same applies to facsimile.

[0005] Now that telephones are used at home, after the telephones are sold in stores, plug jacks (called modular connections) have been established so that they can be connected without the qualification of a construction supervisor. Are connected). Like an AC power outlet on a wall in a house, it corresponds to an outlet for connecting a telephone to a communication line, and can be easily removed by anyone. In recent years, telephones called cordless telephones, which consist of a master unit and a slave unit, and have a means for communicating with the low-power radio between the master unit and the slave unit, can be used anywhere in the home, so that telephones can be called anywhere. ing. In addition, a plurality of slave units can be connected to the master unit. This low-power radio has different frequency bands and procedures depending on the application, and the cordless telephone and the radio for security use are different. Now,
The ringing signal of the bell from the telephone exchange is 16 Hz and an AC signal with an effective value of 75 V is set to 1 every 2 seconds.
It is a signal that lasts for seconds. The ringing signal of the same bell no matter where the call comes from.

[0006] Recently, a portable telephone called a personal handy horn (PHP) has appeared.
In a house, it plays the same role as a cordless phone handset, and outdoors, it can be used as a mobile phone that can access a public network.

[0007]

However, such a conventional technique has the following problems.

(1) It must be installed at a high place on the outer wall of the house, which is dangerous and takes much time for construction. In addition, since the work of screwing the communication line is required, the construction work requires the qualification of a construction supervisor.

(2) Installation of the second terminal such as a telephone in the house cannot be easily changed unless the cable of the communication line is laid again.

(3) The configuration of the terminal network control device has only a handset and a button for designating a dial number, and a circuit for transmitting a push button signal and a direct current of a telephone line (communication line) like a telephone. It has a loop switching circuit. Therefore, it is expensive as a whole.

(4) Upon receiving a report from the terminal network control device, the remote terminal uses the information displayed on the screen of the CRT or the like or on the printing device to recognize the telephone number or the like of the contact. You have to call again to confirm and take appropriate action.

(5) Even if the remote terminal calls the telephone connected to the terminal network control device by telephone, it is not possible for the resident having the terminal network control device to immediately recognize that the emergency is urgent. .

(6) For example, between a hospital room and a nurse center, calling from a nurse center by voice using a speakerphone installed in a specific hospital room and talking with a patient can be performed by a remote terminal. It cannot be performed between telephones on the terminal network controller side. Therefore, it hinders home nursing in an aging society. In addition, 1
It is very inconvenient to dial 19. For example, suppose a fire has occurred. You have to go to the phone, dial, and give your address, phone number, and name, and ask for help, in a big upset.
Meanwhile, fires are growing. In addition, a two-person family has an acute illness, and the same is true of phone calls while nursing. Even with the spread of cordless phones, there are handset units in several places in the house. This is even more so when living alone.

(7) If the telephone or the like is disconnected from the communication line due to mischief of a child, emergency contact may not be possible.

(8) Since the terminal network control device uses only a battery as a power source, the communication frequency and usage are limited.

The terminal network control device 1 of the third embodiment incorporates a second terminal 103, and has the same functions as those of the first embodiment. The second terminal 103 differs from the first embodiment in the following points. In the first embodiment, the second
The terminal 103 has a telephone as an example. Therefore, the telephone has built-in functions corresponding to the network control means 4, such as opening and closing of a DC loop circuit of a communication line, transmission of a selection signal, and detection of a calling signal (bell ringing signal). The second terminal 103 in the third embodiment does not require any means corresponding to the network control means 4, and uses the network control means 4. Therefore, the second terminal 103 may be configured with a telephone number input operation unit for transmitting a selection signal, a receiver, a sound source generating unit for sounding a bell, and a speaker.

Accordingly, a terminal network control device having the same appearance as that of a conventional telephone as shown in FIG. 6 is obtained. Then, by integrating the components, the number of members can be reduced.

Although a telephone is taken as an example of the second terminal, the same applies to a facsimile. A fourth embodiment will be described. The terminal network control device 1 according to the fourth embodiment includes an impedance matching unit for sharing an antenna for the wireless communication unit 2 as an antenna for the second connection unit 7 for connecting the second terminal by wireless communication. This is added to the terminal network control device 1 of the second embodiment. When there are two kinds of radio frequencies of a communication path for communicating with the first terminal and two kinds of radio frequencies of a communication path for communicating with the second terminal, for example, an impedance matching unit is mounted on the antenna to share the antenna. It can be realized by adjusting the number of turns, the length, and the pitch of the turns of the helical antenna so that two types of wireless transmission and reception for wireless communication can be performed most efficiently with one helical antenna.

Next, a fifth embodiment will be described. This fifth
In the terminal network control device 1 of the second embodiment, a wireless transmission path sharing unit for sharing the wireless transmission path of the wireless communication unit 2 and the wireless connection unit 8 is added to the terminal network control unit 1 of the second embodiment. . As a wireless transmission path sharing means, for example, when a low power wireless cordless telephone is connected as the second terminal, one of a plurality of cordless telephone channels is used as a wireless transmission path with the first terminal. By taking the method, the first terminal and the second terminal can be connected with one RF module.
There is means for realizing both wireless communication with the terminal. Using one channel, the first terminal and the second
There is also a means used as a wireless transmission path with the terminal. Further, there is a means for using a wireless transmission path specified by a personal handy horn (PHP) to share the wireless transmission path.

A sixth embodiment will be described with reference to FIG. The terminal network control device according to the sixth embodiment is the same as that of the second embodiment. However, the network control means 4 includes an access means 8 for the data communication means 5 to access the communication line to connect to the remote terminal 102, and a terminal selection means 9 for selecting the second terminal 103 to be connected to the remote terminal 102. And the second
And the access support means 10 for connecting the terminal 103 to the remote terminal 102.

FIG. 7B shows a system configuration using the terminal network control device 1 in the sixth embodiment. A first terminal 100 is a gas meter, and a second terminal 103a;
Reference numerals 103b and 103c denote devices similar to cordless telephone handsets. Therefore, the second connection means 7 of the terminal network control device 1 plays the role of a base unit of the cordless telephone. It is assumed that the terminal selecting means 9 is preset to select the second terminal 103b among the second terminals 103a, 103b, 103c in response to a request from the data communication means 5.

The operation of the sixth embodiment will be described. When the gas meter of the first terminal 100 detects, for example, that a gas amount equal to or more than a predetermined value has continuously flowed, the gas meter gives a notice of closing a shutoff valve in the gas meter. This notice is received by the relay means 6 via the wireless communication means 2. The relay unit 6 connects to the remote terminal 102 by using the data communication unit 5 and the network control unit 4 and transmits a telegram of the advance notice. At this point, the remote terminal can determine from where the advance notice is from (for example, address, name of householder, telephone number). Subsequently, when performing communication by voice call, the remote terminal 102 transmits a message indicating this request. Upon receiving this message, the data communication unit 5 requests the network control unit 4 to set up a communication path between the remote terminal 102 and the second terminal 103. The access support means 10 is connected to the second terminal 103b and the remote terminal 10 by the instruction of the terminal selection means 9.
2 is set up. The remote terminal 102 communicates with the second terminal 103b by voice call,
Prevent disaster prevention by appropriate instructions or confirmation from

In setting a communication path for voice communication, the second terminals 103a and 103 for voice communication are set.
As a means for selecting one of b and 103c, there is also a means for designating the remote terminal 102 by a message. For example, "
If “1” is specified in the message, the second terminal 2a
2 "is specified in the message, the second terminal 2b is
If 3 "is specified in the message, the second terminal 2c is selected. The role of the terminal selecting means 9 is specified in the message."
1 "," 2 "," 3 "and the second terminals 103a, 103
It has a correspondence table of each wireless address of b and 103c, and operates so as to obtain a wireless address from designation of a message. Further, priority information for terminal selection of the second terminals 103a, 103b, 103c may be provided.

The seventh embodiment will be described with reference to FIG. First, the terminal network control device of the seventh embodiment is the same as that of the first embodiment. FIG. 10 shows the configuration of the network control means 4 in the seventh embodiment. Other means are the same as in the first embodiment. The access means 8 and the terminal selection means 9 constituting the network control means 4 are the same as in the sixth embodiment. It is assumed that the communication line 101 is an analog telephone line. Accordingly, the access means 8 of the network control means 4 includes a switch for opening and closing a DC loop circuit of the telephone line for accessing the telephone line. An access support unit 10 according to the seventh embodiment will be described. The access support means 10 includes a second
Calling means 11 for sending a signal for calling to the terminal 103, response detecting means 12 for detecting a response of the second terminal 103, and a remote terminal which is an example of a communication path setting means. And switching means 13 for switching communication with the communication device 102. The calling means 11 outputs, via the second connecting means 7, a 16-Hz effective value 75 which is a ringing signal of a bell.
A V AC signal is transmitted. The switching means 13
The communication between the data communication means 5 and the remote terminal 102 is switched to the communication between the second terminal 103 and the remote terminal 102. Since various ways of realizing the switching means 13 are conceivable, the switching means 13 is illustrated by a changeover switch having a logical meaning. When this switch is closed, the second terminal 10 does not matter whether the DC loop circuit of the telephone line of the network control means 4 is opened or closed.
3 is electrically connected to the communication line 101. The second terminal 103 is a telephone.

Now, the operation of the seventh embodiment will be described. In response to a request from the gas meter, which is the first terminal 100, the terminal network control device 1 calls the remote terminal 102 and reports. Prior to the notification, the network control means 4 disconnects the second terminal 103 by the switching means 13 immediately before connecting to the remote terminal 102.
This prevents the second terminal 103 from affecting the communication between the data communication means 5 and the remote terminal 102.
The currently used terminal network control device is also the means being performed. Now, it is assumed that the data communication means 5 keeps the connection with the remote terminal after the notification and waits for a message from the remote terminal 102. Here, it is assumed that the data communication unit 5 receives a switching-only message from the remote terminal 102. When the data communication means 5 receives the message exclusively for switching, a switching request is issued to the network control means 4. The network control means 4 activates the calling means 11 and sends out a bell ringing signal. When the bell of the second terminal 103 rings and the handset of the second terminal 103 goes off-hook, this is detected by the acknowledgment detecting means 12, and the switching means 13 switches the second terminal 103 and the remote terminal 102.
Switch to communication with. When the receiver of the second terminal 103 is hooked on, the remote terminal 102 and the second terminal 10 are connected.
Communication with No. 3 ends.

In this way, by transmitting the information of the transmission source by the data communication means 5, the remote terminal 102 can determine from where the report originated. Further, the remote terminal 102 can have a conversation with the caller without performing the procedure of calling the second terminal 103 by the instruction to the terminal network control device 1. Further, an existing telephone can be used as the second terminal 103 as it is.

Now, an example will be described in which the calling means 11 includes a sounding means for generating a plurality of calling signals and a selecting means for selecting a calling signal of the sounding means in response to a request from the data communication means 5. Terminal network control device 1 in the seventh embodiment
In the case of, for example, two types of ringing means for generating a plurality of ringing signals are provided: a means for continuously transmitting an AC signal having a 16 Hz effective value of 75 V, and a means for transmitting one second for every two seconds. And When the calling means 11 of the access support means 10 is driven by the data communication means 5 receiving a message having a high urgency meaning dedicated to switching, the sounding means is switched by the selecting means to a 16 Hz effective value of 75 V. It is driven so as to continuously transmit an AC signal. When a message having a low urgency is received, the selection means drives the sounding means to transmit an AC signal having a 16 Hz effective value of 75 V for one second every two seconds.
