The present invention relates to improvement of a data collection processing system for transmitting to a data processing device for processing.

Hereinafter, it is assumed that the data type is represented by a 4-bit data type identification code, the number of terminals is 4 and represented by 2 bits, and the actual data of each terminal can be represented by 2 bits.

[0003]

2. Description of the Related Art FIG. 10 is a block diagram of a conventional data collection processing system. 10 rather than terminals 1 ′ to 4 ′.
As shown in (a), a 4-bit data type identification code and 2
Data consisting of bit actual data is periodically transmitted to the data collection device 10 '.

The connection position with 2 ', 3', 4'is fixed, and the data input from the terminals 1 ', 2', 3 ', 4'can be known from which terminal without the terminal number. Enter without a number.

Further, in the frame output to the transmission line 25, as shown in FIG. 10 (b), the terminals 1 ', 2', 3 ', 4'have the terminals 1', 2 ', 3', 4 '. FIG. 1 from terminals 1 ′, 2 ′, 3 ′, 4 ′, in which time slots for
The 4-bit data type identification code shown in 0 (a) and the 2-bit actual data are input and transmitted. Of course, for example, terminal 1 '
Even when there is no data transmission, the time slot for the terminal 1'is transmitted with an empty slot.

The memory 53 of the data processing device 40 for receiving this is provided with a data area 41 of the terminal 1 ', a data area 42 of the terminal 2', a data area 43 of the terminal 3 ', and a data area 44 of the terminal 4'. When this data is received, the data storage means 51 stores the data sent from the time slot for the terminal 1'in the data area 41 of the terminal 1 ', and the terminals 2', 3 ', The data sent from the time slot for the terminal 4'is the terminal 2 ',
The data is stored in the data areas 42, 43 and 44 of the terminals 3'and 4 '.

First, the operation of the data collection processing system will be sequentially described with reference to FIGS. 2, 4, 5, 8, and 9. Terminal 1
.. to 4 are binary numbers 00, 01, 10 and 11, and the data format transmitted from the terminals 1 to 4 is, as shown in FIG. 8A, a data type identification code 60, a terminal number 61, and actual data 62. And

As shown in the data processing program of FIG. 4, the processing of the data processing means (data processing program) 13 of the data collection device 10 sends the reception permission signal 50 shown in FIG. , And the data from the terminals 1 to 4 is received in step 2, and the process proceeds to step 3.

In step 3, the data type detecting means 11 and the data extracting means 12, which will be described in detail later, are operated,
From the received terminal data, for each data type, the number and number of terminals that have transmitted the same type of data, the terminal number and the actual data are detected and extracted, and the process proceeds to step 4, where as shown in FIG. Next, according to the contents detected and extracted by the data type detection means 11 and the data extraction means 12, except for the data that is not sent from the terminal, the same type of data that has been sent is grouped, and for each data type, The data type identification code 60, the number 63 of the data of the data type, the terminal number 61 of each of the data of the data type and the actual data 62 are arranged to form one frame, and the process proceeds to step 5, where the created frame is transmitted.
