[0022] Secondary matching is also called secondary matching of process equipment ("Hook up"), which connects the process equipment with various main pipelines. The working range is from the Take off valve (point) of each main system in the clean room to the POU (Point of User, hereinafter referred to as POU). Since there are many kinds of pipeline systems in the clean room and the pipelines are densely arranged, the workload of secondary matching is very large. The pipeline systems and machine equipment that need to be processed have a lot of connections, and the wiring is also relatively complicated. The present invention configures the pipeline system, that is, secondary matching, to improve the accuracy of the generated process pipeline and instrument flow chart.

[0023] The method for generating a process piping and instrumentation flow diagram of a device in the present invention is suitable for execution in a computing device. The computing device includes: one or more processors; a memory; and one or more devices, wherein the one or more devices include instructions for executing the method for generating a process piping and instrumentation flow diagram according to the device.

[0024] In a basic configuration, a computing device includes at least one processing unit and system memory. According to one aspect, depending on the configuration and type of the computing device, the system memory includes, but is not limited to, volatile storage (e.g., random access memory), non-volatile storage (e.g., read-only memory), flash memory, or any combination of such memories. According to one aspect, the system memory includes an operating system.

According to one aspect, the computing device has additional features or functions. For example, according to one aspect, the computing device includes additional data storage devices (removable and / or non-removable), such as disks, optical disks, or tapes.

According to one aspect, the program module can be implemented as one or more computer program products, and the present application does not limit the type of computer program products, for example, it can include: email, word processing application, spreadsheet application, database application, slide show application, painting or computer-aided application, web browser, etc. In some embodiments according to the present application, a computer program / instruction related to a method for authenticating a user is packaged as a computer program product, and when these computer programs / instructions are executed by a processor (i.e., a processing unit), a method for generating a process piping and instrument flow chart of a device according to the present application is implemented.

[0027] The invention also discloses a device for generating a process pipeline and instrument flow chart of the equipment. Figure 1 FIG. 1 is a schematic diagram of a device 100 for generating a process piping and instrumentation flow diagram of an apparatus according to an exemplary embodiment of the present invention. Figure 1 As shown, the device 100 for generating a process piping and instrumentation flow chart of a device includes a data reading module 110 , a piping size configuration module 120 and a CAD graphics generation module 130 .

[0028] In the following, each module in the device 100 for generating a process piping and instrumentation flow chart will be further described in each step of the method for generating a process piping and instrumentation flow chart of a device.

[0029] Figure 2 FIG. 2 is a flow chart showing a method 200 for generating a process piping and instrumentation flow chart of a device according to an exemplary embodiment of the present invention. Figure 2As shown, method 200 first executes step 210, and in response to receiving a drawing request for drawing a process pipeline and instrument flow chart, calls a data reading module to obtain target interface information of one or more interfaces from a machine requirement table, wherein the target interface information includes flow information and interface information, and the interface information includes interface size.

[0030] According to one embodiment of the present invention, a machine requirement table (UM table) is stored in a computing device. The machine requirement table can be entered by a developer or obtained from a business docking party. The present invention does not limit the specific method of obtaining the machine requirement table. The UM table can be specifically implemented as an Excel table, and the present invention does not limit the specific storage form of the UM table. The UM table stores interface information of interfaces corresponding to different points. Points include demand contacts of machines or auxiliary machines, etc. Each row in the UM table records the interface information of an interface corresponding to a point, and each column records a data type in the interface information. The interface information includes: component name, floor, maximum flow, minimum flow, maximum pressure, minimum pressure, interface material, interface form and interface size, etc.

[0031] According to one embodiment of the present invention, the UM table is stored in a target storage location in a computing device. The computing device can automatically search for the target storage location, or the target storage location can be manually set by a user, and provided to a device for generating a process piping and instrumentation flow diagram of a device that executes a method for generating a process piping and instrumentation flow diagram of the device.

[0032] According to an embodiment of the present invention, in response to a device for generating a process piping and instrumentation flow chart of a device receiving a drawing request for drawing a process piping and instrumentation flow chart, a data reading module processes the drawing request. The data reading module includes a path positioning submodule ( Figure 1 The target storage location of the UM table can be automatically located, or the target storage location set by the user can be received. The data reading module obtains the UM table according to the target storage location. The target storage location includes the storage disk path and file name where the UM table is stored in the computing device. An example of the target storage location is as follows: C:\Semiconductor_ Projects\UM_Demand_ Table. Xlsx.

[0033] According to an embodiment of the present invention, when the data reading module obtains the target interface information of one or more interfaces from the UM table, it determines one or more data types required to process the drawing request, matches each data type in the UM table to determine the target column where the data type is located; calls the acquisition function to obtain the target interface information from the target column of the machine demand table; for example, the data reading module calls the read_excel function in the pandas library of Python to extract the target interface information of one or more interfaces. The target interface information includes the flow information, interface size, etc. extracted from the interface information.

[0034] According to an embodiment of the present invention, the data reading module creates a data frame for storing target interface information. The data frame is similar to a matrix, with n horizontal rows and p vertical columns, but each column is allowed to have different types: numeric type and character, etc. The data frame can be stored in an independent data buffer area applied in the memory, so that the pipeline size configuration module obtains the target interface information in the data frame from the data buffer area. The present invention does not limit the specific storage location of the data frame.

[0035] After extracting the target interface information, the data reading module stores the target interface information in a data frame.

[0036] Then, step 220 is executed to call the pipe size configuration module to determine the pipe size of the branch pipe connected to each interface according to the target interface information of each interface.

[0037] According to an embodiment of the present invention, the pipeline size configuration module is suitable for monitoring the data buffer: when it is determined during the monitoring process that the target interface information of one or more interfaces is stored in the data frame of the data buffer, it indicates that the data reading module has successfully extracted the target interface information of the interface from the UM table, and the pipeline size configuration module obtains the flow information (including the maximum flow of the interface) and the interface size of each interface from the data frame in the data buffer. The flow information and interface size of each interface are sent to the pipeline size configuration function as input parameters of the pipeline size configuration function. Among them, the flow information of the interface includes the maximum flow of the interface, and the unit of the maximum flow of the interface can be specifically set to LPM (liter per minute). The present invention does not limit the specific unit of the flow information. If the pipeline size configuration module receives a drawing request during the process of monitoring the data buffer, and exceeds the preset time threshold, and still does not monitor the target interface information stored in the data frame, an error is reported, indicating that the data reading module fails to extract the target interface information, and reminds manual intervention to handle the error.

[0038] According to one embodiment of the present invention, a pipe size configuration function (configure_pipe_size function) is defined in the pipe size configuration module. The input parameters of the pipe size configuration function include the maximum flow rate and the interface size of the interface. After receiving the input parameters sent by the pipe size configuration module, the function automatically starts to execute, and calculates the output parameters according to the input parameters, and the output parameters include the pipe size of the branch pipe connected to the interface.

[0039] The pipe size configuration function is preset with a pipe size matching rule set based on the engineering practice experience of the semiconductor industry and the main requirements of related businesses. The matching rules in the pipe size matching rule set form a logical branch for matching pipe sizes with a series of conditional judgment statements. An example of a matching rule is as follows: When matching the pipe size of a pure water system, when the maximum flow value passed in is judged to be less than 10 L / Min, the preset pipe size of the branch pipe selected according to the rule should be OD20. The pipe size configuration module determines the preset pipe size of the pipe connected to the interface based on the maximum flow of the interface and the pipe size matching rule set.

[0040] Subsequently, the pipe size configuration module calls the pipe size configuration function to determine the pipe size according to the size relationship between the preset pipe size and the interface size; including: if the interface size is less than or equal to the preset pipe size, the preset pipe size is used as the pipe size; if the interface size is greater than the preset pipe size, the interface size is used as the pipe size. The pipe size configuration function strictly follows this rule logic to compare, match and calculate the input parameters one by one, and finally determines the accurate pipe size that is suitable for the branch pipe connected to the current interface.

[0041] Then, step 230 is executed to call the pipe size configuration module to determine the access mode of the branch pipe to the system according to the pipe size of each branch pipe and the interface information of the system to be connected.

[0042] According to one embodiment of the present invention, the pipeline size configuration module includes a pipeline merging function (pipe_combine function). The input parameters of the pipeline merging function include the pipeline size of each branch pipe and the interface information of the system. The system is a pipeline system deployed inside the plant, such as a pure water system, bulk gas, special gas, pure water (UPW), wastewater (Drain), chemicals (Chemical), process circulating cooling water (PCW), process vacuum (PV), cleaning vacuum (HV), vacuum pipe (Pumping line), exhaust (Exhaust), PW, CW, NG, etc. During calculation, all branches to be connected to the system belong to the same system, and the access method of the branch pipes of each system is calculated separately. The interface information of the system to be connected includes the system interface size and the maximum flow rate of the system interface. The interface information of the system is the information of the take off point of the system. In order to minimize the number of points to be connected to the system, the branches to be connected to the same system are merged to reduce the number of points to be connected to the system. The system interface size and the maximum flow rate of the system interface of each system are also stored in the pipeline merging function. When the pipeline merging function is operated, different branches to be connected to the system are connected to the main pipe, so that the branches are merged through the main pipe, and then each main pipe is connected to a corresponding point on the system; and the flow rate of each main pipe is averaged, and the flow rate of each main pipe is less than the maximum flow rate of the system interface. The output of the pipeline merging function is the access method of the branch pipe to the system. The access method of the branch pipe to the system includes the number of points opened by multiple branches connected to the system, that is, the number of main pipes required to connect to the system, and one or more branches connected to each main pipe. When each branch pipe is connected to the main pipe, the interface size of the corresponding point when the branch pipe is connected to the main pipe can be set according to the size of the branch pipe.

[0043] According to one embodiment of the present invention, in a pure water system, there are 7 branch pipes to be connected to the system, of which 4 branch pipes have a maximum flow rate of 60 (for the convenience of calculation, a unified unit such as L / Min is taken), and 3 branch pipes have a maximum flow rate of 40. The size of the system interface connected to a single take off point of the system is OD63, and the maximum flow rate of the system interface is 300. After calculation, it can be determined that the 7 branch pipes are connected to the system through two take off points, that is, two main pipes are set to connect to the system, one takeoff point (that is, the main pipe) is allocated to connect 2 60 branch pipes and 2 40 branch pipes, and the other take off point (that is, the other main pipe) is allocated to connect 2 60 branch pipes and 1 40 branch pipe.

[0044] According to one embodiment of the present invention, each step performed by the pipeline size configuration module can be specifically implemented through Python code, and the present invention does not limit the specific implementation method of the pipeline size configuration module.

[0045] The pipe size configuration module can store the pipe size of the branch pipe and the access method of the branch pipe to the system in the size configuration result buffer area.

[0046] Finally, execute step 240, call the CAD graphics generation module, and generate the process pipeline and instrument flow chart of the equipment according to the pipeline size of the branch pipe and the access method of the branch pipe to the system; including: creating a graphic object in the drawing, and setting the graphic object according to the pipeline size of the branch pipe and the access method of the branch pipe to the system. The graphic object includes an image frame; marking the flow information, interface information, interface name and system name of the branch pipe to be connected to the graphic object in the image frame; setting the instrument valve group to control each branch pipe; connecting the branches connected to the same system to the main pipe, and merging the branches connected to the same system through the main pipe; setting the main pipe to be connected to the system. According to one embodiment of the present invention, the flow information of the interface includes the maximum flow, average flow and minimum flow of the interface. For example, the maximum flow of a certain interface is marked as 4, the average flow is 2, and the minimum flow is 0, and the unit is LPM.

[0047] According to one embodiment of the present invention, the CAD graphics generation module can interact with AutoCAD software based on the pyautocad library, and automatically generate a process piping and instrumentation flow chart (P&ID) of the equipment according to the configured branch pipe size and the access method of the branch pipe to the system.

[0048] According to one embodiment of the present invention, the CAD graphics generation module first initializes the connection with AutoCAD. In the startup phase, the CAD graphics generation module first loads the connection initialization function module of the pyautocad library. According to the version information of the AutoCAD software installed in the computing device and the default installation path configuration, a communication connection with the running or activatable AutoCAD process is established. The communication connection is achieved by sending a predefined connection request instruction and verification information, ensuring that the interaction channel between the CAD graphics generation module (which can be implemented as a Python program) and the AutoCAD software is unimpeded, laying the foundation for subsequent graphics drawing operations.

[0049] Subsequently, the functions and methods provided by the pyautocad library are used to create graphic objects in AutoCAD, such as lines, symbols, and annotations, and the graphic objects are set according to the pipe size of the branch pipe read and the access method of the branch pipe to the system, and a complete drawing is drawn according to the specifications and layout requirements of P&ID. First, the preset drawing layout of different systems is obtained according to the data reading module (including the horizontal position and vertical spacing of each element, the representative legend of each element in CAD, etc.). Subsequently, after extracting the pipe size data from the size configuration result buffer of the pipe size configuration module, the CAD graphics generation module officially starts the drawing operation. The rich drawing functions provided by the pyautocad library are used, such as using the create line function to draw the pipeline direction line according to the take-off point and the point coordinate position information, and setting text annotations according to the pipeline size data to intuitively reflect the different pipe diameters; for special symbol identifications such as valves and instruments, the pre-set CAD blocks are called, and the CAD parameter blocks are used to annotate the flow value, interface size, material, form, pressure, etc. of the interface. During the entire drawing process, the standard layout framework of P&ID is strictly followed to ensure that the position, direction, and connection relationship of each graphic object conform to the engineering drawing logic and industry practices. Finally, the generated AutoCAD file is saved. After all graphics drawing and annotation work is completed, the CAD graphics generation module triggers the file saving process. According to the user's pre-set save path (which can be set by default to the "PID_Flowchart" subfolder in the same directory as the requirement table, or can be manually specified by the user) and the file name specification (such as naming according to the project number, date, version number and other information to ensure the uniqueness and identifiability of the file name), the file save command of the pyautocad library is used to save the currently drawn P&ID in the AutoCAD native file format (such as .dwg format) to the specified location. After saving, the connection with AutoCAD is automatically closed, the relevant system resources are released, and the prompt message "a certain machine + P&ID is drawn and saved successfully" is fed back to the user interface, completing the entire implementation process of this auxiliary drawing method.
