The present invention relates to a remote information system using a main distribution frame (hereinafter referred to as MDF). In particular, the home service unit (hereinafter referred to as HSU) function can be used to service not only the meter reading but also additional functions. It is about a method. The conventional remote information system reads using the test trunk 4 of the switchboard 3 as shown in FIG. In the operation of performing the meter reading, the host computer 1 transmits the desired meter reading information of the desired subscriber to the exchange interface unit (hereinafter referred to as EIU) 2 using a dedicated line or a telephone line. The EIU 2 having received the metering information dials the corresponding subscriber via the test trunk 4 of the exchange 3. After the dialing, the EIU 2 communicates with a subscriber interface unit (hereinafter referred to as SIU) 5 through a modem MODEM to transmit metering information to the SIU 5, which is then sent to the SIU 5. The meter reading information is sent to the EIU (2). The EIU 2 recovers the line after receiving the metering result from the SIU 5 and sends the metering result to the host computer 1. The host computer 1 receives and stores the meter reading result. However, since the subscriber needs to be dialed at every meter reading, the meter reading time is long, and the dialing method is different for each exchange type. Therefore, there is a problem of adding and changing hardware and software according to the exchange.

In addition, since the test trunk is limited and the test trunk is extended, there is a limit, and thus the number of subscribers that can be read at the same time has a problem that the reading time is long to read many subscribers.

5 is a flowchart of FIG. 4, (A) is a flow chart of meter reading and alarm function service, and (B) is a flow chart of broadcasting and data service function.

Based on the above configuration, the present invention will be described in detail with reference to FIGS. 2-5. First, as shown in FIG. 2, the subscriber of the combined remote information system using the MDF 14 which attaches the LCA 13 to the MDF 14 of the exchange 23 to serve many subscribers simultaneously regardless of the exchange type. The invention relates to the function of the HSU 15 installed in the terminal. When the information request data is received from the LCS 12 to the HSU 15, the MIU 20 collects the meter value of the meter 21 and sends information to the HSU 15 when there is no abnormal state and there is a request for meter reading. .

The HSU 15 sends the meter reading result to the LCS 12 to be processed by the host computer 10. At this time, it does not matter whether the subscriber reads the phone or not. When the abnormal state occurs, the alarm or the MIU 20 abnormal state data, which is abnormal state data, is sent from the HSU 15 to the LCS 12 and processed by the host computer 10. The alarm condition is detected by the sensor 18 to determine whether the subscriber receives the alarm service at the alarm service switch 19.

When the alarm is received, the alarm service status display unit 26 and the alarm occurrence display unit 17 are displayed, and the buzzer 24 sounds.

In addition, the HSU 15 periodically scans the PC 22, analyzes the data when a service request comes from the PC 22, and causes the display to the PC 22 when the broadcast data service request is made. If the data service request is requested, the telephone number of the host computer 10 is dialed from the HSU 15 and the subscriber's request data is transmitted to the host computer 10 through the exchange 23 and the dial-up modem 11. Here, the subscriber cannot use the telephone for the data service and the telephone can be used when the data service is over. Referring to the communication procedure shown in Figs. 4A and 4B for the above operation, first, the reading and alarm service method of (A) will be described below.

In step 51, the HSU 15 periodically sends the MIU state request information to the MIU 20. In step 52, the HSU 15 receives the MIU state information from the MIU 20 and stores the result. In addition, when the subscriber receives the alarm service, the sensor 18 is always scanned to keep the alarm occurrence.

In step 53, the HSU 15 sends a response signal to the LCS 12 in step 54 when a response request signal is received from the LCS 12. The response signal transmits an abnormal state occurrence signal when an abnormal state occurs and transmits a pure response signal when the abnormal state does not occur.

When the information request data is sent from the LCS 12 in step 55, when an abnormal condition occurs, the alarm, MIU error status data, which is the abnormal status data as the information request response data from the HSU 15, is sent to the LCS 12 in step 60. Send it out.

If the abnormal condition does not occur, the meter request data is sent from the HSU 15 to the MIU 20 in step 57. In step 58, the meter reading result information is sent to the HSU 15. Therefore, the reception response information is sent from the HSU 15 to the MIU 20.

The HSU 15 transmits the information request response data to the LCS 12 in step 60, and receives the response data from the LCS 61 to terminate the operation. In the step 55, if the information request data is the broadcast data, the broadcast status display lamp 25 is turned on to indicate that there is broadcast data. If the information request data is an error, the data is requested by retransmission in step 56. Receive again. Next, in the broadcast and data service function flow chart of (B), in step 62, the HSU 15 periodically scans the PC 22 to check whether the subscriber is to receive data service or broadcast data. In step 63, when the service request comes from the PC 22 to the HSU 15, the data is analyzed and the broadcast data is displayed on the PC 22 in step 64 to receive the broadcast data.

When the service request requests the data service, in step 65, the telephone number of the host computer 10 is dialed from the HSU 15 to connect the telephone line, and the request data of the subscriber is transferred to the host computer 10 in step 66 when the telephone line is connected. Send it out. The host computer 10 transmits the response data indicating that the request data of the subscriber has been received to the HSU 15 in step 67, and sends the result to the PC 22 in step 68. If the service is continuously requested, the above steps (66-68) are repeated. In addition, when the subscriber wants to terminate the service, the service termination request data is sent from the PC 22 to the HSU 15 in step (69), and the service termination request data is sent to the host computer 10 in step (70). Hangs up the phone line.

The above process is described below with reference to the flowcharts shown in FIGS. 5A and 5B.

First, in step (1A), the MIU 20 status request is sent from the HSU 15, and in step 2A, the MIU 20 status is received, and then step (3A) is performed. In the step (3A), if the state of the MIU 20 is good, the first time is performed again. If the state is abnormal, the first time is performed after storing the information in the HSU 15.

In step (5A), if the communication request from the LCS (12) has not been checked, the first step is performed again. If it is, in step (6A), the response signal is sent to the LCS (12). After the response signal is sent, in step 7A, it is checked whether the information request comes from the LCS 12. If the information request does not come, the first step is performed again. In step (8A), it is checked whether there is an abnormal state in the current HSU 15, and if there is an abnormal state, in step 9A, an abnormal state such as an alarm, an error of the MIU 20, an error of the HSU 15, or the like is detected. Perform the initial state after sending out to 12).

If there is no abnormal state in step (8A), in step (10A), the initial state is performed after transmitting data for the information request. Next, in step (1B) in (B), the HSU 15 checks the state of the PC 22, and in step (2B), it is checked whether a service request comes from the PC 22.

If the service request does not come, the first operation is performed. If the service request arrives, step 3B is performed to check whether the broadcast data service request is made. If the broadcast data service request is made, the broadcast data is displayed on the PC 22 in step 4B, and if it is not the broadcast data service request, step 5B is performed. In step (5B), it is checked whether the data service request is performed, and if the data service request is not performed again, if it is a data service request, in step (6B), the telephone number of the host computer 10 is dialed and then step (7B) is performed. Perform.

In step (7B), information request data is sent to the host computer 10, and in step 8B, response data is sent from the host computer 10 to the HSU 15 and displayed on the PC 22. After performing step (8B), in step (9B), it is determined whether the service is terminated, and if the service is not terminated, step (7B) is performed again. If the service is terminated, the initial state is performed.

As described above, the meter reading time can be reduced by several tens to hundreds of times while using the remote metering system using the MDF, and additional hardware can be added to the remote alarm, broadcasting function, and data service function as an additional service function. Service can be performed without the advantage that you can use the intercom line of the apartment, not the exchange in the future.
