BACKGROUND OF THE INVENTION
The present invention relates to a data communication system that periodically communicates from a center and receives operation information of a terminal, and more particularly, the charging time is reduced by the terminal creating operation information when a communication call is received from the center. The present invention relates to a data communication system capable of transmitting the latest information without lengthening it.
[0002]
[Prior art]
In a data communication system using a plurality of communication lines, connecting a large number of terminal devices, and performing regular communication, information on the terminal device usage status and error occurrence status is obtained from each terminal device as operation information of each terminal device. It is received and analyzed. Conventionally, the operation information of each terminal device is appropriately created on the terminal device side and transmitted when a communication call is made from a communication center. Alternatively, when a serious error occurs, a call may be made from the terminal device.
[0003]
In general, each terminal device side appropriately stores the situation when a report item occurs such as when the terminal device is used or when an error occurs. These report items are created as operation information at regular time intervals or when there is room in the terminal device for the convenience of the terminal device. Then, when there is a communication call from the communication center and the operation information transmission request is received, the created operation information is transmitted to the communication center.
[0004]
However, with this method, the latest operation information cannot always be transmitted. That is, if the time elapses from when the operation information is last created until the transmission request is received from the communication center, some report items may occur during that time. Therefore, in order to be able to transmit the latest information, a method of creating operation information after receiving a communication call from a communication center and connecting is considered.
[0005]
[Problems to be solved by the invention]
However, in the method of creating the operation information after starting communication, the operation information is the latest information, but the operation information is included in the communication time even during creation of the operation information. Accordingly, the communication time corresponding to the operation information creation time is charged, and the communication cost is increased accordingly. In other words, the method of creating operation information as appropriate on the terminal device side does not necessarily create the latest information, and the method of creating information during communication has a problem that the communication cost increases.
[0006]
The present invention has been made to solve the above-described conventional problems, and an object thereof is to provide a data communication system capable of transmitting the latest operation information without increasing the communication cost.

[0008]
In the data communication system according to the first aspect, when the call detecting means of the terminal device detects a communication call from the data communication center, the operation information creating means creates the operation information. As a result, the latest operation information can be transmitted to the data communication center.
In addition, after the operation information creation unit of the terminal device finishes creating the operation information, the communication start unit connects the communication line. Accordingly, since communication is not started while the operation information is being created, the latest operation information can be transmitted to the data communication center without increasing the communication cost.
[0009]
The data communication system according to claim 2 is characterized in that, in the data communication system according to claim 1, the data communication center provides a certain waiting time from communication call to the terminal device to connection of a communication line. .

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, a data communication system according to the present invention will be described in detail with reference to the drawings based on embodiments embodying the present invention. First, a schematic configuration of the data communication system according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a schematic configuration of a data communication system. Here, the communication karaoke system will be described.
[0013]
In FIG. 1, the data communication system is basically divided into a center device 1 and a terminal device 10. The center device 1 is provided with a communication device 2 used for communication with the terminal device 10. Here, other devices are omitted.
[0014]
On the other hand, the terminal device 10 is mainly configured by the CPU 11, and includes a communication device 12 used for communication with the center device 1, a karaoke device 13 for performing karaoke performance, karaoke song data, usage status, error occurrence status, and the like. A storage device 14 for storing the terminal information is connected to the CPU 11. Further, the CPU 11 stores the call detection unit 15 that detects a communication call from the center device 1, the communication start unit 16 that connects the communication line when starting communication with the center device 1, and the storage device 14. An operation information creation unit 17 that creates operation information to be reported to the center apparatus 1 using terminal information such as the current use status and error occurrence status is included.
[0015]
Next, in the data communication system configured as described above, an operation of creating and transmitting operation information in the terminal device 10 in response to a communication call from the center device 1 will be described with reference to FIG. FIG. 2 is a flowchart of a communication program that creates and transmits the latest operation information in response to a communication call from the center apparatus 1. In FIG. 2, the flowchart A is a flowchart of the communication program A that operates in the center device 1, and the flowchart B is a flowchart of the communication program B that operates in the terminal device 10. Communication program A and communication program B are simultaneously executed in center device 1 and terminal device 10, respectively.
[0016]
In FIG. 2, in order to transmit the latest operation information, first, in step (hereinafter abbreviated as “S”) 100, a communication call is made from the center device 1 to the terminal device 10. Usually, a communication call is made once a day, and music data of a new song is transmitted and operation information is received. The communication call timing is determined by the center device 1, and communication is possible even when the terminal device 10 is using the karaoke performance.
[0017]
On the other hand, in the terminal device 10, the call detection unit 15 appropriately determines whether or not a communication call to the communication device 12 has been made (S200). When a communication call is made from the center apparatus 1 in S100, it is determined that a communication call is made by detecting a call sound (S200: YES). When a communication call is made, the terminal device 10 activates the operation information creation unit 17 to create operation information (S210). The creation of the operation information uses data stored in the storage device 14 and takes 1 to 2 seconds. When the creation of the operation information is completed, the communication start unit 16 automatically takes a call and connects the communication line (S220). Normally, the center apparatus 1 has a waiting time of 45 seconds until the connection of the communication line, so that sufficient operation information can be created during that time.
[0018]
During this time, the center apparatus 1 waits for a communication line to be connected (S110). When the communication line is connected (S110: YES), an operation information transmission request is sent after processing such as transmission of new song data (S120).
[0019]
When receiving the operation information transmission request (S230: YES), the terminal device 10 transmits the previously created operation information to the center device 1 (S240). The center device 1 receives the operation information (S130), and since all the processes are completed, the communication line is disconnected (S140). Since the terminal device 10 also ends the communication process, the communication line is disconnected (S250), and the process ends.
[0020]
As described above in detail, in the data communication system according to the present embodiment, when the call detection unit 15 detects a communication call from the center device 1, the operation information creation unit 17 creates the operation information, and the creation of the operation information is completed. After that, since the communication start unit 16 connects the communication line and starts communication, the latest operation information can be transmitted without increasing the communication cost.
[0021]
In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning. For example, although the communication karaoke system has been described here, information communication such as electricity and gas meter reading result information and sales status of vending machines can also be performed.
[0022]
【The invention's effect】
As described above, in the data communication system according to the first aspect, when the call detection unit of the terminal device detects a communication call from the data communication center, the operation information generation unit generates the operation information. Thereby, the latest operation information can be transmitted to the data communication center.
In addition, after the operation information creation unit of the terminal device finishes creating the operation information, the communication start unit connects the communication line. Thereby, since the communication is not started during the creation of the operation information, the latest operation information can be transmitted to the data communication center without increasing the communication cost.
[0023]
In the data communication system according to the second aspect , the operation information can be sufficiently generated during the waiting time.
[0024]
The data communication system according to claim 3 is data communication in a communication karaoke system. In the communication karaoke system, each data communication center has a large number of communication karaoke terminal devices, and it is necessary to periodically receive and analyze the operation information of all the terminal devices. According to the data communication system having the above configuration, The latest operation information can be received without increasing the communication cost.
[0025]
As described above, the present invention can provide a data communication system that can transmit the latest operation information without increasing the communication cost.
