DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a data transfer terminal installed in a subscriber terminal when a call is received from one of the data collection centers to the exchange. While the weighing data is automatically transferred to the data collection center, if any abnormal situation occurs on the subscriber terminal side, the content of the abnormal situation is automatically transferred to the relevant report destination center as emergency notification data. The present invention relates to a data transfer method from a subscriber side to a center, and further relates to a data transfer terminal device for enabling such data transfer.

[0002]

2. Description of the Related Art Hitherto, as a method of collecting numerical information and the like using a public network, a method using a "no ringing communication service" provided by Nippon Telegraph and Telephone Corporation (hereinafter simply referred to as NTT) has been known. (NT
(See the technical reference “Interface of No-ringing Communication Service” issued by T). According to the data collection method using the no-ringing communication service, a business (power,
A gas company, etc.) is a Type 1 telecommunications carrier (in this case,
It is required in advance to make a no-ringing communication contract with NTT for setting up a contract line.
A non-ringing trunk (hereinafter simply referred to as NRT) as a dedicated device for the no-ringing communication service is provided on the exchange side, and a terminal device for the no-ringing communication service is provided on each subscriber side in addition to the original subscriber terminal. It is something that needs to be installed.

FIG. 6 shows an example of a relay system when the data collection method using the no-ringing communication service is carried out. The data collection method will be briefly described as follows. is there. That is, as shown in FIG. 6, for the subscriber (telephone) line from the receiving station 3 to each of the subscribers (only one subscriber is shown for simplicity of illustration), the original subscriber terminal (telephone terminal) is provided. Etc.) In addition to 4B, a terminal device (N
Includes CU (network control circuit) and accommodates various meters) 4A
Are connected in parallel and branched. In such a state, assuming that it is necessary to remotely collect data measured by various meters from the subscriber in the data collection center 1, the data collection center 1 first sends the data to the receiving station 3. In order to be connected to the accommodated NRT5, the connection control signal NR follows the telephone number corresponding to the NRT5.
TS (2,765 Hz signal) is transmitted from the calling station 2 via the contract line.
The transmission station 2 checks whether the connection request to the NRT 5 is from a contract line. If it is from a contract line, its N
RT5 is connected to the data collection center 1 for the first time and
From the RT 5, the second selection signal request signal SDR (1,700 Hz signal) is returned to the data collection center 1 in response to the reception of the connection control signal NRTS from the data collection center 1. . If the data collection center 1 receives the second selection signal request signal SDR, the connection control signal NR
While transmission of TS is stopped, NRT5 also
In response to the disconnection of the connection control signal NRTS, the return of the second selection signal request signal SDR is stopped.

After that, the data collection center 1 waits for the reception of the second selection signal request signal SDR to be cut off, and then the connection control signal NRTS following the telephone number corresponding to the subscriber.
A communication line is established between the data collection center 1 and the NCU in the terminal device 4A under the control of the NRT 5, and a response signal is returned from the NRT 5 to the data collection center 1. Is what it is. In the data collection center 1, after receiving the response signal, data communication for data collection is performed with the terminal device 4A in a state where the connection control signal NRTS is transmitted as the NRT connection indication signal. Things. Eventually, if the transmission of the connection control signal NRTS from the data collection center 1 is stopped with the end of the data communication, the reception of the connection control signal NRTS is interrupted, and the communication line set up until then is set by the NRT 5. It has been released.

[0005]

However, the above-mentioned data collection method using the no-ringing communication service not only requires a dedicated contract line but also easily copes with the relocation of the data collection center itself. It cannot be done. Further, special hardware equipment, that is, a connection control signal NRT is provided on the data collection center side.
An S transmitting device and a receiving device for the second selection signal request signal SDR are required. Further, the connection control signal NRTS must be transmitted during data communication, and a modem (modulator / demodulator) used for a normal telephone line for data communication cannot be used. Furthermore, when data is collected from the subscriber side, a complicated connection control procedure is required. In other words, in the past, not only could the data transfer center itself not be easily relocated, but data could not be easily and economically collected from the subscriber side. .

On the other hand, apart from data collection from the subscriber side, in the conventional security / disaster prevention monitoring system, a dedicated communication device is prepared or monitored in order to include location information in the monitoring status information. It is not only necessary to transfer the status information to the monitoring center as individual information, but also it is difficult to flexibly deal with the addition of the monitoring status information and the relocation of the monitoring center itself.

[0007] A first object of the present invention is to enable metering data on a subscriber side to be easily and economically collected from a data collection center, and to be automatically transferred to the data collection center. If any abnormal situation occurs on the subscriber side, the contents of the abnormal situation can be easily and automatically transferred to the relevant report destination center as emergency notification data.
The purpose is to provide a method of transferring data from the subscriber side to the center. A second object of the present invention is to automatically and economically transfer weighing data on the subscriber side to the data collection center based on a request from the data collection center, When an abnormal situation occurs, a data transfer terminal device capable of easily automatically transferring the contents of the abnormal situation as emergency notification data to a related report destination center is provided.

[0008]

The first object of the present invention is to basically provide a subscriber telephone line paired with a subscriber terminal for a subscriber telephone line from an exchange to each subscriber terminal. In the state where the terminal device for data transfer is connected at the same time, the call is sent from the exchange prior to a call signal from the exchange to the subscriber terminal in response to an incoming call request from the general source to the subscriber terminal. After the caller identification information indicating the caller is received on the data transfer terminal device, one or more of the caller identification information are stored on the data collection terminal device, and If it matches any of the caller identification information corresponding to the data collection center, the connection to the subscriber terminal of the subscriber telephone line is released by the data transfer terminal device, and the call signal from the exchange is applied to the call signal from the exchange. Terminal device for data transfer After the automatic response, the data transfer terminal device automatically transfers the weighing data pre-collected for the corresponding data collection center to the transmission source data collection center, while the subscriber terminal has no data. If such an abnormal situation occurs, the data transfer terminal device disconnects the connection with the subscriber terminal of the subscriber telephone line by the data transfer terminal device at that time, and An automatic call is made using the telephone number corresponding to the pre-set relevant report destination center, and the contents of the abnormal situation are automatically transmitted to the relevant report destination center via the exchange as emergency notification data with the caller identification information from the exchange. Achieved by being transferred.

A second object of the present invention is that, as constituent elements, source detecting means for receiving and detecting caller identification information indicating a source, which is transmitted from the exchange prior to a call signal, and a specific source as a specific source. A specific sender setting means in which one or more caller identification information corresponding to the data collection center is preset as updatable, and a sender comparison means for comparing each of the sender identification information corresponding to the data collection center with the detected sender identification information. A data collection means for collecting weighing data corresponding to the data collection center; an abnormal situation detecting means for detecting an abnormal situation corresponding to the sensor based on a sensor signal from each sensor; A call destination setting means in which a telephone number corresponding to the relevant report destination center is preset so that the relevant report destination center is automatically called in response to an abnormal situation; In a state where the connection with the subscriber terminal line is released, and the origination request detecting means for detecting a call request from a subscriber terminal, detection and the call signal from the exchange
When a call response is made and the detected caller identification information matches any of the data collection center-corresponding caller identification information, or when the relevant report destination center is automatically called, the data transfer is terminated until the data transfer is completed. Line disconnection means for forcibly connecting the subscriber's telephone line to the subscriber's terminal while disconnecting the subscriber's telephone line from the subscriber's terminal while detecting a call request from the subscriber's terminal And after responding to the call signal, via the line disconnection means,
Upon receiving various control data from the subscriber's telephone line, the metering data from the data collection means is sent out to the subscriber's telephone line. On the other hand, when an abnormal situation occurs, based on the telephone number from the call destination setting means, This is achieved by providing at least a data transmission / reception means for automatically transmitting a call to a call destination and transmitting abnormal content as emergency notification data to the subscriber telephone line after the call destination responds.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
5 will be described with reference to FIG. First, prior to the specific description of the present invention, the "calling telephone number display service" used for data collection according to the present invention will be described. This service has already been offered on a trial basis by NTT in some areas (Yokohama and Fukuoka) since January 1997 with the goal of providing the service in full scale in 1997. (1996)
November 2008, published by The Telecommunications Association, pages 8 to 26). This service allows N
Each of the subscriber terminals accommodated on the TT public telephone network receives caller identification information (caller telephone number) prior to displaying a ring tone by a call signal when a call is made from an exchange in response to an incoming call request from a caller. The caller's name, address, etc., based on the number, may be received and displayed on the subscriber terminal, thus easily recognizing the caller before the called subscriber answers the call. That is what is possible.

Here, the "calling telephone number display service" will be briefly described with reference to FIG. 2 as follows. That is, among the plurality of subscriber terminals 6 accommodated in the transmitting station 2, the subscriber terminal having the telephone number "#AA" is regarded as the originating subscriber terminal and the plurality of subscriber terminals 7 accommodated in the terminating station 3 are set. Among them, assuming that the subscriber terminal having the telephone number "#BN" is called as the called subscriber terminal, the originating station 2 transmits "#BN" from the originating subscriber terminal.
When there is a transmission request to the destination station (which may be the same as the transmission station 2), data indicating transmission from "#AA" to "#BN" is transmitted to the receiving station 3. I have. The sender name, address, and the like can be added to “#AA” as a part of the data.
, Based on the data from
A "is transmitted to the terminating subscriber terminal as data in the voice frequency band by a predetermined communication procedure, and then the terminating subscriber terminal is called by the transmission of the calling signal from the terminating station 3, but the terminating subscriber terminal is called. Responds to the call, the calling subscriber terminal and the receiving subscriber terminal are connected for the first time, and a call / communication between these subscriber terminals is enabled.

As described above, before the called party answers the call, "#AA" is visually displayed on the called subscriber terminal, a ringing tone corresponding to the "#AA", or a calling display by voice message. Is performed, the called party can easily know the calling subscriber in advance, so that necessary measures (such as determining whether or not to answer the call,
Selection of the person who should respond). The above-mentioned document "NTT Technical Journal" discloses electrical interface conditions and communication procedures for transmitting and receiving data as caller identification information when the "calling telephone number display service" is performed. In fact, the devices that receive the data have already been developed by each terminal device maker before the trial from January 1997.

Now, the present invention will be described in detail, and its outline is as follows. In other words, according to the present invention, when the above-mentioned "calling telephone number display service" is used and the data collection center selectively makes an incoming call request to the subscriber side, the subscriber side requests the incoming call. The desired weighing data is automatically transferred to the data collection center,
FIG. 3 shows an outline of a data collection system in which such data collection is enabled. As shown in the drawing, for example, data collection centers A to C are installed by a power company, a gas company, and a municipal government in order to collect, for example, power consumption, gas consumption, and water consumption per month from the subscriber side. Are housed on the public telephone network. On the other hand, each subscriber as a consumer has a subscriber line (not shown) from the public telephone network and a subscriber line corresponding to the subscriber. Terminal devices a to n
Is connected and accommodated. Thus, for example, in order to remotely collect the power consumption per month from the data collection center A, it is sufficient that the subscriber terminals are sequentially called. Prior to the call, each of the data transfer terminal equipments a to n receives the caller identification information from the public telephone network, and if it is identified that the data transfer terminal A is compatible with the data collection center A,
Without the subscriber terminal being actually called, each of the data transfer terminal devices a to n responds to the call from the public telephone network, and the power consumption per month previously collected separately from the integrating wattmeter is reduced. The measurement data is automatically transferred to the data collection center A via the public telephone network. At this time, the data collection center A does not necessarily need to be a subscriber who subscribes to the “calling telephone number display service”, but each subscriber as a consumer needs to be a subscriber to the calling telephone number display service. It is said that. However, at this time, if each of the subscribers as consumers is not a subscriber of the “calling telephone number display service”, the power company in advance requests the “calling telephone number display service” provider to provide those subscribers. Each of them can be handled as if they were subscribers of the "calling telephone number display service". Such a situation is the same for each of the data collection centers B and C.

On the other hand, on the public telephone network, apart from the above-mentioned data collection centers A to C, a plurality of reporting centers (not shown) related to crime prevention and disaster prevention are accommodated in correspondence with the types of crime prevention and disaster prevention. However, if any abnormal situation occurs on the subscriber side and this is detected by the abnormal situation detector, the abnormal state is detected on the data transfer terminal devices a to n at that time. The situation is an emergency interrupt, an automatic call is made using the telephone number corresponding to the relevant report destination center that has been set in advance to deal with the abnormal situation, and the contents of the abnormal situation are transmitted as emergency notification data via the public telephone network from the public telephone network. Is automatically transferred to the relevant report destination center with the sender identification information. Based on the emergency notification data and the caller identification information, the relevant notification destination center can immediately take necessary measures.

Hereinafter, the present invention will be described more specifically.
FIG. 1 shows an example of a relay system in which a method of transferring data from a subscriber to a center according to the present invention is enabled. As shown in the figure, when weighing data is collected from the subscriber terminal 4B via the transmitting station 2 and the receiving station 3 under the initiative control of the data collection center 1, the receiving station 3 sends the caller identification information. Subsequently, a call signal is sent to the subscriber terminal 4B. The subscriber terminal 4B receives a call via the data transfer terminal device (including an NCU (network control circuit) and accommodating various meters) 4C according to the present invention. In addition to being accommodated and connected to the subscriber line from the station 3, a telephone number corresponding to the data collection center 1 is also preset on the data transfer terminal device 4C. Therefore, after the caller identification information from the receiving station 3 is received on the data transfer terminal device 4C, and if it matches the telephone number corresponding to the data collection center 1, the subscriber terminal of the subscriber line In a state where the connection to 4B is released, the data transfer terminal device 4C responds to the call signal from the receiving station 3, and the weighing data is transferred from the data transfer terminal device 4C to the data collection center 1. Is what it is.
Also, if the caller identification information does not match the telephone number corresponding to the data collection center 1, the connection of the subscriber line to the subscriber terminal 4B is not released, and Ordinary “calling phone number display service”
Is displayed.

On the other hand, in the case where a related report destination center is provided separately from the data collection center 1, any abnormal situation that occurs on the subscriber terminal 4B side, that is, a state change is determined by the relation report destination. It can be notified to the center. The abnormal situation of various sensor signals is detected by the abnormal situation detector, and the abnormal situation is used as an emergency interrupt.
In a state where the connection of the subscriber line to the subscriber terminal 4B is released from the data transfer terminal device 4C, an automatic call is made using the telephone number corresponding to the relevant report destination center which is set in advance to deal with the abnormal situation. In addition, the contents of the abnormal situation are automatically transferred to the relevant report destination center as emergency notification data.

FIG. 4 is a block diagram showing an example of the data transfer terminal device 4C according to the present invention. The block configuration will be described below. That is,
As shown in FIG. 4, the data transfer terminal device 4C includes, as a component thereof, a detection circuit (source detection means) for receiving and detecting caller identification information indicating a caller, which is transmitted from the exchange prior to a call signal. 10), a registration circuit (specific source setting means) 11 in which one or more data collection center corresponding sender identification information as a specific source is preset as updateable, and a data collection center corresponding sender identification information. (Sender comparing means) 12 for comparing the data with the detected sender identification information, and a data collection circuit (collectively shown for simplification of the drawing) for collecting weighing data corresponding to the data collection center
(Data collecting means) 16, abnormal state detecting means (not shown) for detecting an abnormal state corresponding to the sensor from the sensor signal from each sensor, and, when any abnormal state occurs, responding to the abnormal state The connection between the call destination setting means (not shown) in which the telephone number corresponding to the relevant report destination center is preset and the subscriber terminal of the subscriber telephone line is released so that the relevant report destination center is automatically called. In this state, a call request detecting circuit (call request detecting means) 14 for detecting a call request from the subscriber terminal, a call signal from the exchange, and a call response are performed, and the detected caller identification information is data. If any of the caller identification information corresponding to the collection center is matched, or if the relevant report destination center is automatically called, the subscriber of the subscriber telephone line until the end of data transfer. A line switching circuit (line connection releasing means) 13 for forcibly connecting the subscriber's telephone line to the subscriber's terminal when a call request from the subscriber's terminal is detected while releasing the connection to the terminal; After responding to the signal, receiving various control data from the subscriber's telephone line via the line disconnecting means, transmitting the weighing data from the data collecting means onto the subscriber's telephone line, In the event of occurrence, a data transmission / reception circuit (data transmission / reception circuit (data transmission / reception circuit (data transmission / reception circuit)) which automatically makes an outgoing call to the called party based on the telephone number from the above-mentioned called party setting means and sends out the content of the abnormal situation as emergency notification data to the subscriber's telephone line after answering the called party. (Transmitting / receiving means) 15 at least.

As shown in FIG. 5, various sensors 17 are accommodated on the data transfer terminal device 4C, and based on sensor signals from each of the various sensors 17, the abnormal condition detecting means uses a sensor. In response, an abnormal situation is detected as a state change. In addition, in the data transmission / reception circuit 15, when the weighing data is collected, various control data from the subscriber telephone line, that is, the data collection center, can be received together with the caller identification information. This is because when the caller identification information needs to be changed due to the relocation of the data collection center itself, the caller identification information corresponding to the data collection center on the data transfer terminal device 4C also needs to be updated. However, the update is performed by control data from a data collection center. The control data is also provided for specifying the type of weighing data to be collected when one data collection center permits, for example, various weighing data to be collectively collected. Whether all weighing data is transferred or only specific weighing data is transferred from the data transfer terminal device 4C depends on the designation by the control data. However, if the telephone number corresponding to the relevant report destination center is also preset in the registration circuit 11, the corresponding telephone number corresponding to the relevant report destination center on the call destination setting means is based on the control data from the relevant report destination center. The telephone number can also be easily updated and controlled.

On the twentieth page of the above-mentioned document "NTT Technical Journal", the "calling telephone number display service" between the called subscriber's line exchange (called station) and the called terminal is described. Although such a connection operation sequence is shown, in the case of this connection operation sequence, when the caller identification information (caller ID) is transmitted as a modem signal from the called station, the called terminal transmits the subscriber terminal 4B before the modem signal. The polarity of the subscriber lines L1 and L2 is inverted, and an ID receiving terminal activation signal (L1: battery, L2: activation signal) is sent to the subscriber terminal 4B. On the other hand, on the subscriber terminal 4B side, the polarity inversion is detected, and the primary response signal (DC loop) needs to be returned to the receiving station within 6 seconds from the detection point. .

Here, the operation on the data transfer terminal device 4C in the event of an abnormal situation is clear, and therefore, the description of the operation will be omitted, and the description will be omitted from the calling subscriber (including the data collection center). Various operations on the data transfer terminal device 4C when the subscriber terminal 4B is called in response to the incoming call request will be briefly described below in relation to the subscriber terminal 4B.

(1) Non- "calling telephone number display service" In the case of a general incoming call to the subscriber terminal 4B, in this case, simply, the receiving station side reverses the polarity of the subscriber telephone line to the subscriber terminal 4B side. In addition, the calling signal is transmitted from the receiving station to the subscriber terminal 4B. On the other hand, the data transfer terminal device 4 on the subscriber terminal 4B side
On C, a call signal is detected following the polarity reversal. On the basis of this, on the data transfer terminal device 4C, it is determined that it is not addressed to itself, and the state of the subscriber's telephone line is maintained until the end of the call. It has been monitored.

(2) Non- "calling telephone number display service" In the case of an incoming call to the subscriber terminal 4B with caller identification information corresponding to the data collection center In this case, the receiving station sends the call to the subscriber terminal 4B. The polarity of the subscriber telephone line is inverted, and the polarity inversion is detected on the data transfer terminal device 4C on the subscriber terminal 4B side. From the point of time when the polarity inversion is detected, the status monitoring is performed for a certain period of time (3 to 4 seconds) on the data transfer terminal device 4C. During that time, no call signal is transmitted from the called station and the subscriber is not monitored. Since there is no primary response from the terminal 4B, a primary response is made from the data transfer terminal device 4C to the receiving station. Waiting for this primary response, the receiving station sends the caller identification information to the subscriber terminal 4B side, but this caller identification information is received on the data transfer terminal equipment 4C and the data collection center A match with any of the sender identification information can be detected by comparison with each of the sender identification information. After detecting this match,
In the data transfer terminal device 4C, the ID information reception completion signal is transmitted to the receiving station, and the connection of the subscriber telephone line to the subscriber terminal 4B is released. Further, after that, after waiting for an ID information reception completion signal from the data transfer terminal device 4C, a call signal is transmitted from the called station to the subscriber terminal 4B for the first time, and the call signal is transmitted to the data transfer terminal device. The data transfer terminal device 4C is connected to the data collection center and the weighing data is transferred to the data collection center by performing the call response after being detected on the 4C. .

(3) "Calling telephone number display service" In the case of an incoming call to the subscriber terminal 4B with the caller identification information corresponding to the non-data collection center In this case, the receiving station sends the call to the subscriber terminal 4B side. The polarity of the subscriber telephone line is reversed, and the polarity is reversed by the data transfer terminal device 4C and the subscriber terminal 4 on the subscriber terminal 4B side.
B are both detected. After the detection of the polarity reversal, the primary response from the subscriber terminal 4B is detected on the data transfer terminal device 4C, and the caller identification information transmitted from the receiving station after waiting for the primary response is used for the data transfer. Both the terminal equipment 4C and the subscriber terminal 4B have been received and detected. The caller identification information is compared with each of the data collection center corresponding caller identification information on the data transfer terminal device 4C. The terminal device 4C is in a non-operation state.

(4) "Calling telephone number display service" In the case of an incoming call to the subscriber terminal 4B with caller identification information corresponding to the data collection center In this case, the receiving station joins the subscriber terminal 4B side. The operation from the inversion of the telephone line of the sender to the comparison of the sender identification information detected and received with the data collection center corresponding sender identification information on the data transfer terminal device 4C is as described in the above (3). The same is the case. However, in this case, unlike the case of (3), a match with any of the data collection center-corresponding sender identification information can be detected, and the operation after the match detection is the above (2) ).

[0025]

As described above, according to the first to fourth aspects, basically, the weighing data on the subscriber side can be easily and economically collected from the data collection center. In addition, while the data is automatically transferred to the data collection center, if any abnormal situation occurs on the subscriber side, the content of the abnormal situation can be easily and automatically transferred to the relevant report destination center as emergency notification data. The method of transferring data from the subscriber side to the center, and in the case of claim 5, the weighing data on the subscriber side can be easily and economically based on the request from the data collection center. In the event that any abnormal situation occurs on the subscriber side, the contents of the abnormal situation can be easily and automatically transferred to the relevant report destination center as emergency notification data. Over data transfer terminal device is a one obtained respectively.
