Abstract

A sequence design support system is used to support a design of a sequence control program which controls a flow path condition of a fluid in an apparatus and piping system which is constructed connecting apparatus such as a valve with piping and comprises a valve pattern plan generation unit which generates a valve pattern plan which is plan data showing the flow path condition per time step of the fluid in the apparatus and piping system from apparatus and piping system plan data which is plan data showing the apparatus and piping system and time chart sheet which is obtained defining the condition of the apparatus in the apparatus and piping system per time step.

Claims

1. A sequence design support system which supports a sequence design as a design of a sequence control program which controls a flow path condition of a fluid in an apparatus and piping system which is constructed connecting apparatus such as valve with piping,

which comprises a valve pattern plan generation unit which generates a valve pattern plan which is plan data which shows the flow path condition per time step of said fluid in said apparatus and piping system from apparatus and piping system plan data which is plan data showing said apparatus and piping system and a time chart sheet which is obtained defining a condition of said apparatus in said apparatus and piping system per time step.

2. A sequence design support system of claim 1, wherein said valve pattern plan generation unit comprises a plan recognition processing part and a valve pattern plan generation processing part, said plan recognition processing part individually recognizes apparatus and piping or piping group and the like on said apparatus and piping system plan data, at the same time generates plan recognition data conducting plan recognition processing which is processing which recognizes connection relationship of individually recognized apparatus and the like and relationship of member piping of piping group and the like, and said valve pattern plan generation processing part generates said valve pattern plan using said plan recognition data.

3. A sequence design support system of claim 2, wherein said valve pattern plan generation unit further comprises a figure information database which stores figure information which is information about figure expression of said apparatus and piping and the like on said apparatus and piping system plan data and provides the same to said plan recognition processing part, said plan recognition processing part conducts said plan recognition processing based on said figure information.

4. A sequence design support system of claim 3, wherein said valve pattern plan generation unit further comprises a time chart generation processing part, said time chart generation processing part generates a time chart sheet form used to generate said time chart sheet from said plan recognition data.

5. A sequence design support system of claim 2, wherein said valve pattern plan generation unit further comprises a time chart generation processing part, said time chart generation processing part generates a time chart sheet form used to generate said time chart sheet from said plan recognition data.

6. A sequence design support system of claim 4, wherein the generation of said valve pattern plan in said valve pattern plan generation processing part is conducted including the processing such as first searching a piping terminal of which condition is “

entrance”

, then searching in order the piping connected to the piping terminal of the condition “

entrance”

, and the apparatus connected to said piping based on said plan recognition data, further determining the flow path condition of the fluid in said apparatus and piping system by determining the condition of the searched apparatus by said time char sheet.

7. A sequence design support system of claim 2, wherein the generation of said valve pattern plan in said valve pattern plan generation processing part is conducted including the processing such as first searching a piping terminal of which condition is “

entrance”

, then searching in order the piping connected to the piping terminal of the condition “

entrance”

, and the apparatus connected to said piping based on said plan recognition data, further determining the flow path condition of the fluid in said apparatus and piping system by determining the condition of the searched apparatus by said time char sheet.

8. A sequence design support system of claim 6, wherein said valve pattern plan is generated in a form which displays the flow path condition of the fluid in said apparatus and piping system by the change of display condition of said piping on said apparatus and piping system data.

9. A sequence design support system of claim 1, wherein said valve pattern plan is generated in a form which displays the flow path condition of the fluid in said apparatus and piping system by the change of display condition of said piping on said apparatus and piping system data.

10. A sequence design support system of claim 8, wherein said valve pattern plan generation unit further comprises a plan recognition data editing processing part to conduct the editing of said plan recognition data.

11. A sequence design support system of claim 2, wherein said valve pattern plan generation unit further comprises a plan recognition data editing processing part to conduct the editing of said plan recognition data.

12. A sequence design support system of claim 10, wherein said time chart sheet has a table form which has a line which arranges each apparatus on said apparatus and piping system plan data, a column which arranges said time step, and a definition section in which said line and said column cross, and the condition of said apparatus is defined in said definition section.

13. A sequence design support system of claim 1, wherein said time chart sheet has a table form which has a line which arranges each apparatus on said apparatus and piping system plan data, a column which arranges said time step, and a definition section in which said line and said column cross, and the condition of said apparatus is defined in said definition section.
