Abstract

A remote controlled meter check system having a host computer, which can provide actually stored information on subscribers from the subscribers database, and a connecting device to an operator, the host computer checks the communication lines by sending a message to the operator through the connecting device requesting for actually stored information on subscribers loaded. If the lines are in good order, text information on subscribers are sent to the operator. The information received from the host computer is stored to the operator connecting device memory.

The present invention relates to a method of loading subscriber information in a remote meter reading system. Particularly, each subscriber is controlled by providing subscriber mounting information to an exchange matching device based on a subscriber database included in a meter reading host computer. The present invention relates to a method of loading subscriber mounting information in a remote meter reading center.

In general, the subscriber mounting information refers to data information on whether the subscriber interface connected to the switch matching device is mounted. Based on this implementation information, the switch matching device is an indispensable data because it connects and controls each subscriber interface.

By the way, the subscriber mounting information is contained in a state of "1" if the corresponding subscriber is actually in the memory in the switch matching device, and "0" if it is not mounted.

In the conventional case, the method of loading subscriber mounting information was adopted by inputting one subscriber one by one through a console terminal connected to the subscriber matching device. Concerns have arisen due to errors. In addition, since the total subscriber information of the actual system is contained in the host computer, there is a problem that the difference between the subscriber information on the actual database and the input subscriber data occurs.

Accordingly, an object of the present invention is to configure subscriber mounting information using a subscriber database of a host computer that supervises the metering system when loading the subscriber mounting information, and configures the subscriber mounting information and automatically delivers the subscriber mounting information to the exchange matching device. It provides a method for loading implementation information.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a system configuration diagram according to the present invention, which includes a host computer 10 which transmits subscriber mounting information and metering instructions and collects and manages a meter reading result, and a metering terminal terminal 11 operating the host computer 10; And an exchange matching device (20) for interfacing with the host computer (10) to form a communication path for performing various services such as providing remote meter reading and providing remote information and subscriber mounting information by scanning a subscriber. Input from the multiplexer 30 to connect the subscriber and the communication path by the subscriber scanning signal of), the exchanger 31 connected to the multiplexer 30 and performing the exchange function, and the meter 40 The meter value is composed of a subscriber interface unit 50 that integrates, and a telephone 32 provided between the multiplexer 31 and the subscriber interface 50.

2 is a communication procedure of the present invention, in which the first process (100-101) of checking the state of the communication line lines of the host computer 10 and the switch matching device 20, and if the communication line line is satisfactory, the subscriber mounting. A second process (102-104) of transmitting the information text (TEXT), and a third process of storing the subscriber mounting information received from the host computer 10 in the memory of the switch matching device (20).

3 is a detailed flowchart according to the subscriber mounting information loading protocol of FIG.

The present invention will be described in detail based on the above configuration.

First, an operation of transferring subscriber mounting information from the host computer 10 as the meter reading center to the switch matching device 20 will be described.

In step (A1), the host computer 10 receives the subscriber mounting information input by the system operator from the terminal 11 of the meter reading center. After accepting the subscriber mounting information as described above, the subscriber database is configured by inputting the subscriber mounting information configured in step (A2).

After the operation of the database, the process proceeds to step (A3) to read the subscriber information from the subscriber database and construct a subscriber mounting information message.

When the configuration of the subscriber mounting information message is completed in step (A3), the process proceeds to step (A4) and transmits the subscriber mounting information load command reception request signal to the switch matching device 20. At this time, the switch matching device 20 checks whether the request for receiving the command from the host computer 10 is properly received in step (B1) (the above is the first of the subscriber mounting information loading protocol shown in FIG. 2). Corresponding to steps 100-101). If the reception request is properly received in step (B1), the process proceeds to step (B2) and transmits a normal response (ACK) to the host computer 10. In this case, if the host computer 10 checks whether or not the normal response is received in step (A5) and determines that the normal response has been received, the host computer 10 proceeds to step 46 to transfer the subscriber mounting information load command text to the switch matching device 20. send.

On the other hand, the switch matching device 20 checks whether the subscriber mounting information text is normally received in step (B3), and when it is determined that the text is normally received, proceeds to step (B4) and returns a normal response to the switch matching device 20. Send (ACK). However, if the text is not normally received, the process proceeds to step (B5) and transmits a negative response (NAE) to the switch matching device 20 (the second step of the subscriber mounting information loading protocol shown in FIG. 102-104). The switch matching device 20 having transmitted the normal response in step (B4) performs the actual operation of storing the subscriber mounting information received from the host computer 10 in the memory (the above is the subscriber mounting information shown in FIG. 2). Corresponds to the third phase of the loading protocol). Thereafter, the host computer 10 checks whether a normal response (ACK) is received from the switch matching device 20 in step (A7). If it continues, the above-described operation is not repeated, and if not, the operation ends.

As described above, by automatically supplying subscriber mounting information in the remote metering system to the switch matching device, it is not only possible to prevent input errors when the subscriber mounting information is inputted by subscribers one by one through the console terminal, but also save time. There is an advantage to this.

Claims (1)

In a remote metering system having a host computer 10 and an exchange matching device 20 capable of constructing a subscriber mounting information message from a subscriber database, the subscriber mounting information is transferred from the host computer 10 to the switch matching device 20. In the loading method, the host computer 10 transmits a request for receiving a subscriber mount information load command to the switch matching device 20 to check a state of a communication line line (100-101), and a communication line. If the line is good, the second process (102-104) of transmitting the subscriber mounting information text from the host computer (110) to the switch matching device (20), and the subscriber mounting information received from the host computer (10) Subscriber mounting information loading method characterized in that consisting of a third process of storing in the memory of the device (20).
