(1) In CAD, the information required for panel design is imported from the control panel specification DB, device specification DB, deployment connection information DB, and standard / design standard DB. (2) In CAD, first, the equipment to be stored in the board is temporarily arranged according to the rules stipulated in the design standard based on the equipment model. The operator reviews and makes detailed adjustments with reference to this result. (3) After deciding the layout of the equipment, decide the wiring and piping route in the panel, and decide the wiring duct piping installation position. (4) After determining the outer shape of the panel and the arrangement of the storage equipment above, check for interference between the equipment. In this interference check, the maintenance space of the equipment is also taken into consideration. (5) As a result of the interference check, if redesign is required, return to (2) and the operator relocates or changes the board dimensions. If there is no problem, create an outline drawing, and at the same time, create related drawings such as equipment installation drawing, wiring route diagram, assembly drawing, etc. and store the data in the outline drawing DB. (6) Create a simulation model based on the above outline drawing data, and perform in-panel heat flow analysis, vibration analysis, electrical system noise analysis, etc. (7) In thermal analysis, when the calorific value of each device is input, the device and component layout are designed while collating the database of design standards including various preset standards and know-how, and the panel / rack / unit. The internal temperature distribution is calculated automatically. If the result deviates from the standard of the temperature inside the panel, the part is discolored on the screen and recognized by the operator. In addition, the heat flow analysis result automatically analyzes what happens to the heat distribution when the air cooling fan is installed near the board surface where the heat flux is concentrated, and the operator is made aware of the result.

(8) The operator refers to it, implements the optimum design in CAD, and confirms it again by thermal simulation. (9) In noise analysis, the cable route diagram from the sensor to the unit, the power cable route diagram in the plant, the position and intensity data of the noise source are taken from the upstream design database, and the signal level of each device is input. Perform noise distribution simulation in the panel. In addition, the result is compared with the noise resistance level of the unit of the database of the design standard including various standards and know-how set in advance, and OK / NG is displayed on the screen for each unit so that the operator can recognize it.
