[0023] Secondary hook-up, also known as process equipment secondary hook-up, connects process equipment to various main pipelines. This work spans the cleanroom from the main system take-off valves (points) to the Point of User (POU). Due to the diverse and densely packed pipeline systems within a cleanroom, secondary hook-up is a significant undertaking. The numerous connections between pipeline systems and equipment require processing, leading to complex routing. This present invention configures the pipeline system, known as secondary hook-up, to improve the accuracy of generated process piping and instrumentation flow diagrams.

[0024] The method for generating a process piping and instrumentation diagram for a device of 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, the one or more devices including instructions for executing the method for generating a process piping and instrumentation diagram for the device.

[0025] In a basic configuration, a computing device includes at least one processing unit and system memory. According to one aspect, 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, depending on the configuration and type of the computing device. According to one aspect, the system memory includes an operating system.

[0026] According to one aspect, an operating system, for example, is suitable for controlling the operation of a computing device. In addition, examples are practiced in conjunction with a graphics library, other operating systems, or any other application program, and are not limited to any particular application or system. According to one aspect, a computing device has additional features or functions. For example, according to one aspect, a computing device includes additional data storage devices (removable and / or non-removable), such as magnetic disks, optical disks, or tapes.

[0027] As stated above, according to one aspect, a program module is stored in a system memory. According to one aspect, the program module can be implemented as one or more computer program products. This application does not limit the type of computer program product; for example, the program module may include: email, word processing applications, spreadsheet applications, database applications, slideshow applications, drawing or computer-aided applications, web browsers, etc. In some embodiments of the present application, computer programs / instructions related to user identity authentication methods are packaged as a computer program product.

[0028] 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 showing a device 100 for generating a process piping and instrumentation flow diagram for 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 an equipment includes a data reading module 110 , a pipe size configuration module 120 and a CAD graphics generation module 130 .

[0029] 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.

[0030] Figure 2 FIG. 2 is a flow chart showing a method 200 for generating a process piping and instrumentation flow chart for an apparatus according to an exemplary embodiment of the present invention. Figure 2As shown, method 200 first executes step 210. In response to receiving a drawing request for drawing a process piping and instrument flow chart, the data reading module is called to obtain target interface information of one or more interfaces from the machine requirement table. The target interface information includes flow information and interface information, and the interface information includes interface size.

[0031] According to one embodiment of the present invention, a computing device stores a machine requirement table (UM table). The machine requirement table can be entered by a developer or obtained from a business partner. The present invention does not limit the specific method of obtaining the machine requirement table. The UM table can be implemented as an Excel spreadsheet. The present invention does not limit the specific storage format of the UM table. The UM table stores interface information corresponding to different points. Points include demand points of a machine or an auxiliary machine. Each row in the UM table records the interface information corresponding to a point, and each column records a data type in the interface information. Interface information includes: component name, floor, maximum flow rate, minimum flow rate, maximum pressure, minimum pressure, interface material, interface type, and interface size.

[0032] According to one embodiment of the present invention, a 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 a user can manually set the target storage location, and provide the target storage location to a device for generating a process piping and instrumentation diagram for a device that executes a method for generating a process piping and instrumentation diagram for the device.

[0033] According to one embodiment of the present invention, in response to a device 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 (not shown) can automatically locate the target storage location of the UM table or receive a target storage location set by the user. The data reading module retrieves the UM table based on the target storage location. The target storage location includes the storage disk path and file name where the UM table is stored on the computing device. An example of a target storage location is as follows: C:\Semiconductor_Projects\UM_Demand_Table.xlsx.

[0034] According to one embodiment of the present invention, when a data reading module obtains target interface information for one or more interfaces from a UM table, it determines one or more data types required to process a drawing request, matches each data type in the UM table to determine the target column where the data type resides, and calls a get function to obtain target interface information from the target column of the machine requirement table. For example, the data reading module calls the read_excel function in the Python pandas library to extract target interface information for one or more interfaces. The target interface information includes flow rate information, interface size, and other information extracted from the interface information.

[0035] According to one embodiment of the present invention, the data reading module creates a data frame to store target interface information. A data frame is similar to a matrix, with n rows and p columns, but each column can contain different types, such as numeric and character. The data frame can be stored in a separate data buffer allocated in memory, allowing the pipeline sizing module to retrieve the target interface information in the data frame from the data buffer. The present invention does not limit the specific storage location of the data frame.

[0036] After extracting the target interface information, the data reading module stores the target interface information in a data frame.

[0037] 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.

[0038] According to one embodiment of the present invention, a pipeline sizing configuration module is adapted to monitor a data buffer. When, during the monitoring process, the data frame in the data buffer contains target interface information for one or more interfaces, indicating that the data reading module has successfully extracted the target interface information from the UM table, the pipeline sizing configuration module retrieves flow information (including the maximum flow rate) and interface size for each interface from the data frame in the data buffer. The flow information and interface size for each interface are sent to a pipeline sizing configuration function as input parameters. The interface flow information includes the maximum flow rate, which can be expressed in liters per minute (LPM). The present invention does not limit the specific units of flow information. If, during monitoring of the data buffer, the pipeline sizing configuration module fails to detect the target interface information stored in the data frame after receiving a drawing request for a predetermined time period, the module reports an error, notifying the data reading module that extraction of the target interface information has failed, prompting manual intervention to address the error.

[0039] According to one embodiment of the present invention, the pipe size configuration module defines a pipe size configuration function (configure_pipe_size). The pipe size configuration function's input parameters include the maximum flow rate and the interface size. Upon receiving the input parameters from the pipe size configuration module, the function automatically begins execution and calculates output parameters based on the input parameters. The output parameters include the pipe size of the branch pipe connected to the interface.

[0040] The pipe sizing function includes a pre-defined set of pipe sizing rules based on semiconductor industry engineering practices and relevant business requirements. The matching rules in this set consist of a series of conditional statements that form logical branches for matching pipe sizes. An example matching rule is as follows: When matching pipe sizes for a pure water system, if the incoming maximum flow rate is determined to be less than 10 L / min, the default pipe size for the branch pipe selected according to the rule is OD20. The pipe sizing configuration module determines the default pipe size for the pipe connected to the interface based on the interface's maximum flow rate and the pipe sizing matching rule set.

[0041] The Pipe Size Configuration module then calls the Pipe Size Configuration function to determine the pipe size based on the relationship between the preset pipe size and the interface size. This includes: 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, comparing, matching, and calculating each input parameter one by one, ultimately determining the correct pipe size for the branch pipe connected to the current interface.

[0042] Then, step 230 is executed to call the pipe size configuration module to determine the connection 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.

[0043] According to one embodiment of the present invention, the pipe sizing configuration module includes a pipe merging function (pipe_combine). The pipe merging function's input parameters include the pipe dimensions of each branch and system interface information. A system is a piping system deployed within a factory building, such as the pure water system, bulk gas, specialty gas, pure water (UPW), drain, chemical, process cooling water (PCW), process vacuum (PV), scavenging vacuum (HV), pumping line, exhaust, PW, CW, and NG. During calculations, all branches connected to the system belong to the same system, and the connection method for each branch is calculated separately. The interface information for the system to be connected includes the system interface dimensions and the maximum flow rate of the system interface. The system interface information refers to the system's take-off point. To minimize the number of points connected to the system, branches connected to the same system are merged to reduce the number of points. The pipe merging function also stores the system interface dimensions and maximum flow rate for each system. The pipe merging function connects the various branch pipes to the main pipe, merging them through the main pipe. Each main pipe is then connected to a corresponding point in the system. The flow rates of each main pipe are averaged, and each main pipe's flow rate is less than the maximum flow rate of the system interface. The output of the pipe merging function is the connection method of the branch pipes to the system. This method includes the number of points at which the branches are connected to the system (i.e., the number of main pipes required to connect to the system), as well as the number of branches connected to each main pipe. For each branch pipe connected to the main pipe, the interface size at the corresponding point can be set based on the branch pipe size.

[0044] According to one embodiment of the present invention, a pure water system has seven branch pipes to be connected to the system. Four of these branch pipes have a maximum flow rate of 60 kilowatts (for ease of calculation, a unified unit, such as L / Min, is used), and three branch pipes have a maximum flow rate of 40 kilowatts. The system interface size connected to a single take-off point in the system is OD63, and the maximum flow rate of the system interface is 300 kilowatts. Calculations have determined that the seven branch pipes are connected to the system via two take-off points. Specifically, two main pipes are connected to the system, with one take-off point (i.e., the main pipe) allocated for connection to two 60-kilowatt branches and two 40-kilowatt branches, and the other take-off point (i.e., the other main pipe) allocated for connection to two 60-kilowatt branches and one 40-kilowatt branch.

[0045] 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.

[0046] The pipe size configuration module can store the pipe size of the branch pipe and the connection method of the branch pipe to the system in the size configuration result buffer area.

[0047] Finally, step 240 is executed to call the CAD graphics generation module to generate a process piping and instrumentation flow chart for the equipment based on the pipe size of the branch pipe and the access method of the branch pipe to the system; this includes: creating a graphic object in the drawing and setting the graphic object based on the pipe 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; and 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.

[0048] According to one embodiment of the present invention, a CAD graphics generation module can interact with AutoCAD software based on the pyautocad library to automatically generate a process piping and instrumentation diagram (P&ID) for the equipment based on the configured branch pipe sizes and the access method of the branch pipe to the system.

[0049] According to one embodiment of the present invention, the CAD graphics generation module first initializes a connection with AutoCAD. During startup, the CAD graphics generation module first loads the connection initialization function module of the pyautocad library. Based on the installed AutoCAD software version information and the default installation path configuration on the computing device, a communication connection is established with a running or activatable AutoCAD process. This communication connection is established by sending a predefined connection request instruction and verification information, ensuring unimpeded interaction between the CAD graphics generation module (which can be implemented as a Python program) and AutoCAD software, laying the foundation for subsequent graphics drawing operations.

[0050] Subsequently, the functions and methods provided by the pyautocad library are used to create graphical objects in AutoCAD, such as lines, symbols, and annotations. Graphic objects are set based on the read branch pipe dimensions and the connection method to the system, and a complete drawing is drawn according to P&ID specifications and layout requirements. First, the data reading module retrieves the preset drawing layout for each system (including the horizontal position and vertical spacing of each element, and the CAD legend for each element). Subsequently, after extracting the pipe dimension data from the dimension configuration result buffer of the pipe sizing module, the CAD graphics generation module begins the drawing process. The rich drawing functions provided by the pyautocad library are utilized. For example, the create line function draws pipe lines based on take-off points and point coordinates, and text annotations are set based on pipe dimension data to visually represent different pipe diameters. For special symbols such as valves and instruments, pre-set CAD blocks are used to annotate the interface flow value, interface dimensions, material, type, pressure, and other information using CAD parameter blocks. Throughout the entire drawing process, the standard P&ID layout framework is strictly adhered to, ensuring that the position, orientation, and connection relationships of all graphic objects conform to engineering drawing logic and industry practices. Finally, the generated AutoCAD file is saved. After all drawing and annotation work is completed, the CAD drawing generation module triggers the file save process. Based on the user-defined save path (which can be set by default to the "PID_Flowchart" subfolder in the same directory as the requirements table, or can be manually specified by the user) and file name specifications (such as a combination of project number, date, and version number to ensure uniqueness and identifiability), the pyautocad library's file save command saves the currently drawn P&ID in its native AutoCAD file format (such as .dwg) to the specified location. After saving, the connection to AutoCAD is automatically closed, releasing related system resources. A prompt message indicating "P&ID for a certain machine has been successfully drawn and saved" is displayed on the user interface, completing the entire implementation process of this assisted drawing method.

The method comprises the steps of: in response to receiving a drawing request for drawing a process piping and instrumentation flow chart, obtaining target interface information of one or more interfaces from a machine requirement table, automatically determining the pipe size of a branch pipe connected to each interface according to the target interface information of each interface, then determining 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, further generating a process piping and instrumentation flow chart for the equipment, automatically configuring corresponding pipeline parameters according to the target interface information, and setting the access mode according to the corresponding parameters, thereby improving the generation efficiency of P&ID and the intelligence of the drawing process.
