DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of lines used in a centralized monitoring system for reporting the amount of gas or water used in each household at a fixed time or reporting security information such as gas leaks to an information center. The present invention relates to a center network control device for controlling the network.

[0002]

2. Description of the Related Art Conventionally, this type of center network control device has
When the report data was received from the terminal, it was transmitted to the host computer, then a response message from the host computer was received and returned to the terminal, and the reception was completed normally.

[0003]

However, in the above-mentioned conventional center network control device, the report data received from the terminal is transmitted to the host computer as it is. When a transmission error occurs, the report data from the terminal cannot be received, and the terminal has not received a response message from the host computer, so it is not known whether the report data has arrived and the report operation must be performed again. There was a problem that had to be.

The present invention has been made to solve such a conventional problem, and is intended to solve the problem even when an incoming call from a terminal, a host computer goes down, or a transmission error occurs with the host computer. It is an object of the present invention to provide a center network control device that can transmit report data received from a host computer to a host computer, and can return a response message to a terminal to terminate reception normally.

[0005]

In order to achieve the above object, the present invention provides a line control means for receiving report data from a terminal and a host computer I / F means for transmitting the received report data to a host computer. And display means for displaying that the report data from the terminal has not been successfully transmitted to the host computer, and a message from the terminal.
Information data cannot be sent to the host computer normally.
Storage means for storing the report data in the event that the report data is sent to the terminal to normally terminate the receiving operation and to send the stored report data to the host computer when requested by the host computer. And a system monitoring control means.

[0006]

Therefore, according to the present invention, when the report data from the terminal is transmitted to the host computer, when the host computer is not started, or when the data is not correctly transmitted to the host computer due to a communication error or the like,
A response message is returned from the system monitoring control means to the terminal via the line control means to end the receiving operation normally, and the display means indicates that transmission was not normally possible to the host computer, and the storage means displays the information from the terminal to the storage means. Even if transmission to the host computer is not normally performed by storing the report data of the host computer, the operator performs the start-up operation of the host computer again, so that the report data stored in the storage means is transmitted to the host computer. This has the effect of being able to transmit.

This is a cable connecting the 2C 32 and the host computer 19. A data bus 34 connects the LCD 35 constituting the display means 17 and the microcomputer 28 constituting the system monitoring control means 14. Reference numeral 36 denotes a power supply of the center network control device 10.

Next, the operation of the above embodiment will be described with reference to FIG. First, when an incoming signal enters the NCU 22 of the line 1 control means 11 from the terminal 18 through the line 21, it is input via the data bus 23 to the input / output control unit 24a of the microcomputer 24 which performs line control for incoming calls. The data is sent to the control unit 24b, the line is captured, and the LED 26 is turned on via the data bus 25. Next, the line control unit 24b receives the report data from the terminal 18 via the NCU 22, and sends it via the data bus 27 to the input / output unit 28a of the microcomputer 28 which monitors and controls the entire system. on the other hand,
The system monitoring control unit 28b controls the host computer I /
The control is entrusted to the F section 28d, and the signal line of the RS232C32 is checked. When it is determined that the host computer 19 has not started up normally, or when an error occurs in transmission with the host computer 19, the system monitoring control unit 28 b sends the line control unit 24 of the line 1 control unit 11.
A response message is sent to the terminal 18 via the terminal b, the line 21 is disconnected, and the LED 26 is turned off. After that, under the control of the display control unit 28c, "COMPLETE ERROR" is displayed on the LCD 35 via the data bus 34, and the report data from the terminal 18 to the center operator cannot be normally transmitted to the host computer 19. Let them know. At the same time, the storage control unit 28 e
The notification data from the terminal 18 is stored in the memory 30 via the. Thereafter, the center operator performs an operation of normally starting up the host computer 19, and operates the cable 33 and the RS2 by operating the key of the host computer 19.
The notification data set in the storage memory 30 is downloaded via the 32C32.

Next, the control operation of each section in the above embodiment will be described with reference to FIG. First, it is checked whether there is an incoming call from the terminal 18 by the line control means 11 to 13 (step 41). If there is an incoming call,
The line is captured by the line control means 11 to 13 (step 42). Next, the notification data is received from the terminal 18 (step 43) and transmitted to the system monitoring control means 14 (step 44). Next, the signal line of the RS232C32 is checked by the host computer I / F means 15 (step 45).
If 9 has risen, the received report data is transmitted to the host computer 19 (step 46).
At that time, it is determined whether or not there is a transmission error (step 47). If there is a transmission error, the system monitoring control means 14 sends the information to the terminal 1 via the line control means 11 to 13.
8 (step 48), and disconnects the line (step 49). Subsequently, the display unit 17 displays "COMPLETE ERROR" to notify the center operator (step 50), and stores the notification data in the storage unit 16 (step 51).

On the other hand, in step 45, the RS323C
When checking 32 signal lines, the host computer 1
When it is determined that the terminal 9 has not been started up normally, a response message is sent to the terminal 18 by the system monitoring and control means 14 (step 48), and the lines are cut off by the line control means 11 to 13 (step 49) and displayed. The display 17 displays "COMPLETE ERROR" (step 50).
The notification data is stored in step 6 (step 51).

As shown in FIG. 4, when the host computer I / F means 15 receives the data request information by the key operation of the host computer 19 (step 5).
2) The notification data from the terminal 18 stored in the storage means 16 is sent to the host computer 19 (step 53).

[0013]

As described above, according to the present invention, when the center network control device is receiving report data from the terminal, when the host computer goes down for some reason, or between the center computer and the host computer, When a transmission error occurs, a response message is returned to the terminal to terminate the reception normally, and the display means displays that the host computer was not able to receive normally and the received report data is stored in the storage means. Therefore, even if the host computer cannot receive the response message from the host computer due to failure to receive the message normally, it can receive the report data from the terminal, and the center operator can restart the host computer. By doing so, the report data from the terminal stored in the storage means can be transferred to the host computer. An effect that can be transmitted.
