[0005]

[Problems to be Solved by the Invention] However, the above-described conventional simulation data input device 5 merely inputs communication data 31, 4 between the first real machine 3 and the second real machine 4.
1 and sends it to the simulator computer 1, and the necessary data selection process is performed within the simulator computer 1. Therefore, the amount of data handled by the simulator computer 1 and the time required for the selection process are enormous. This results in an increase in the processing time of the simulator computer 1, and also increases the burden on the simulator computer 1, which is generally large and expensive, leading to an increase in equipment and running costs.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a simulation data input method that can reduce the burden on a simulator computer, lower the initial cost, and improve the processing time. The goal is to provide equipment.

[0007]

[Means and effects for solving the problems] That is, the present invention selects only necessary data from data communicated between a plurality of actual machines according to a data type command input from a simulator computer, and supplies the selected data to the simulator computer. This reduces the amount of calculations on the simulator computer and shortens its processing time.
The initial cost of the simulator computer can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows the simulation data input device, including the connection configuration with peripheral devices, and Figures 2 and 3 above.
The same parts are given the same reference numerals and their explanation will be omitted.

In the figure, communication data 31 from the first real machine 3 to the second real machine 4 and communication data 41 from the second real machine 4 to the first real machine 3 are both stored inside the data input device 6. It is input from the data input I/F 61 and sent to the CPU 62. The CPU 62 receives the data type command 1 sent from the simulator computer 1 side through the data input/output I/F 64.
5a, select only the necessary data from the communication data 31, 41 input through the data input I/F 61 and store it in the memory 63, and then read out the data held in the memory 63 at an appropriate timing. Data input/output I
/F64 to output to the simulator computer 1 as selection data 64a.

In the simulator computer 1, the CPU 11 outputs the data type command 15a to the data input device 6 side via the data input/output I/F 15, and at the same time outputs the selection data 64a input via the data input/output I/F 15. The selection data 64a is temporarily stored in the memory 13, and a real-time simulation is executed using the selection data 64a stored in the memory 13.

[0011] With the above configuration, the processing contents within the CPU 62 of the data input device 6 will be explained. First, CP
U62 receives communication data 31 through data input I/F 61.
, 41 is performed. At the same time, CP
U62 is the data input/output I/F of the simulator computer 1
The data type command 15a sent from 15 is input via the data input/output I/F 64, and its discrimination processing B2
Do this. The determined data type command 15a is held as is in an internal register or the like. Then, using this held data type command 15a, the data input I
/F61 data selection processing B3 is performed for each command. The data corresponding to the command obtained by this selection process is stored in the memory 63 sequentially. When a certain amount of data is stored in the memory 63, it is read out and the selected data 64a is read out by the data input/output I/F 64 at an appropriate timing. Output processing B4 to the simulator computer 1 side is performed as follows.

Therefore, in the simulator computer 1, by outputting the data type command 15a to the data input device 6, the selection data 64a sent from the data input device 6 is selected as to whether or not it is necessary. Since it can be used as it is for the calculation process C1 for simulation without any processing, and real-time simulation can be quickly executed, the processing time can be shortened to the necessary minimum.

The processes of the data input device 6 and the simulator computer 1 described above are performed in parallel, and even while the CPU 11 of the simulator computer 1 is performing calculations for simulation, the data input device 6 is The CPU 62 performs selection processing of necessary data. Therefore, the CPU of simulator computer 1
11 can be dedicated to simulation calculations,
It is possible to reduce the burden on the CPU 11 and shorten the processing time. This leads to a significant reduction in equipment and running costs for the simulator computer 1, which generally uses a large and expensive computer.
