Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of collecting image data in a large-scale online image data collecting system.

[0002]

2. Description of the Related Art Conventionally, when collecting image data online and registering it in a center system, a file transmission method of directly transmitting several to several tens of image data directly from a terminal device to a host computer, or image data One of the methods of inputting records one by one from a terminal device and directly transmitting the records to a host computer is adopted.

[0003]

In the above-mentioned conventional method, since image data is concentrated on the host computer of the large-scale online image data acquisition system, a processing wait time occurs in the host computer or a data transmission wait time occurs in the terminal device. .. Then, due to these influences, there arises a problem that the usage rate of the terminal device cannot be increased.

Therefore, a communication control device is provided between the host computer and the terminal device, the image data is temporarily stored in a file for temporary storage, and the image data is transmitted at the request of the host computer and the image from the terminal device is transmitted. Operates in parallel with data reception. On the other hand, the terminal device is provided with two image data files, and the input of image data and the transmission to the communication control device are performed in parallel.

An object of the present invention is to provide a method of collecting image data which eliminates the influence of the processing waiting time of the host computer and the transmission waiting time of the terminal device by the temporary storage file and the two image data files.

[0006]

The image data registration method according to the present invention includes a code data entry portion for inputting code data and storing it in a code data file, and image data designated by the code data. An image data entry portion for generating a record and storing it in either the first or second image data file, and data for transmitting the image data record from either the first or second image data file to a local area network line A terminal device having a transmitting unit, a data receiving unit for receiving the image data record transmitted from the terminal device through the local area network line, and a host for storing the received image data record in a temporary storage file. The image data is sent by a computer requesting transmission. Send a composed of a communication control device and a data processing unit for collecting said host computer files online, and the data transmission line which connects the said communications controller host computer.

[0007]

The present invention will be described below with reference to the drawings.

Referring to FIG. 1, which shows the configuration of an embodiment of the present invention, the present embodiment includes a host computer 1 having a file for collecting image data, and a host computer 1.
A communication control device 3 having a temporary storage file 11 for temporarily storing image data, which is connected to the data transmission line 2
And a plurality of terminal devices 5 connected to the communication control device 3 through the local area network line 4, and a plurality of image input devices 6 respectively connected to these terminal devices 5 and inputting image data.

Next, referring to FIG. 2 showing the configuration of the communication control device 3, a data processing unit 10 for receiving image data input from the terminal device 5, and a temporary storage file for temporarily storing the received image data. 11 and a data processing unit 12 that processes and transmits image data according to a request from the host computer 1.

Further, referring to FIG. 3 showing the structure of the terminal device 5, the code data entry section 20 for storing the code data in the code data file 23 and the code data read from the code data file 23 and the corresponding image The image data record unit 21 receives the data input and creates an image data record consisting of the code data and the image data, and stores the image data record in either of the image data files 24 and 25. A data transmission unit 22 that reads out a record and transmits the record to the communication control device 3.

Next, the operation of this embodiment will be described with reference to FIGS. 1, 2 and 3.

The code data entry unit 20 stores the code data input from the terminal device 5 by the operator in the code data file 23. The image data entry unit 21 reads the code data selected by the operator from the code data file 23, reads the corresponding image data from the image input device 6, and creates an image data record composed of the code data and the image data. Either of the image data files 24 and 25 is stored. Then, the image data entry section 21 sends a transmission request to the data transmission section 22. In response to the transmission request, the data transmission unit 22 reads out an image data record from either of the image data files 24 and 25 and transmits it to the communication control device 3 through the local area network line 4. Since the operation of the image data entry unit 21 and the operation of the data transmission unit 22 described above are performed asynchronously with each other, the creation of the contents of the image data files 24 and 25 storing a series of image data records and the transmission thereof are performed simultaneously. Can be done in parallel. Further, in the communication control device 3, the data receiving unit 10 receives the image data record through the local area network line 4, and the temporary storage file 1
Store in 1. The data processing unit 12 reads the image data record from the temporary storage file 11 and transmits it in response to a transmission request from the host computer 1.

[0013]

As described above, according to the present invention, the operations of inputting image data and transmitting data of the image data record can be performed in parallel in the terminal device by providing the first and second image data files. .. Therefore, no waiting time occurs in the operation of inputting image data.

Further, by interposing the communication control device between the host computer and the terminal device, the transmission of the image data record from the terminal device to the communication control device and the transmission from the communication control device to the host computer are performed in parallel. Therefore, the image data record can be transmitted from the terminal device without being affected by the operating state of the host computer.
