[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0050] The terms "including" and "having" and any variations thereof mentioned in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0051] At present, laboratory chemical automation technology for the R&D stage is also developing. In the field of chemical synthesis control systems, a series of different automated instruments or platforms have been derived, mainly focusing on the following: synthesis systems for specific material synthesis scenarios, such as a certain disilane synthesis control system, a certain electrochemical synthesis control system, a certain photochemical synthesis control system, a certain microchannel reactor control system, etc.; synthesis systems for specific synthesis links, these systems are designed to imitate the traditional organic synthesis process and achieve full automation. Such as systems for reaction pipetting, systems for reaction solid addition, systems for reaction stirring, systems for reaction extraction, etc.; synthesis systems based on robotic technology, such systems are centered on robotic arms, etc., and specific system designs are carried out around certain chemical synthesis needs; high-throughput experimental systems, which improve reaction throughput through automation, can be divided into well plate mode and microfluidic mode. For example, a high-throughput chemical reaction screening platform can perform automated reactions under different conditions and screen more than 1,500 reactions in one day.

[0052] However, the existing chemical synthesis control systems have the following technical problems: the existing chemical synthesis control systems are mainly concentrated in the process control of large-scale industrial production, completing the corresponding process control and state scheduling, which is difficult to match the more flexible and low-cost synthesis control system requirements in the research and development stage; the existing laboratory-level chemical synthesis control systems are either designed for certain specific synthesis processes and synthesis products, or for certain specific synthesis processes, which are difficult to match synthesis control solutions for new scenarios; most of the current synthesis systems lack a general and standardized experimental process design, and most of the integration of new hardware has not achieved reconfigurability, scalability, and configurability, making it difficult to match the interface protocol of the new hardware to the synthesis control system.

[0053] Based on this, the embodiments of the present application provide a control system construction method, device and electronic device based on chemical synthesis, through which the above-mentioned technical problems can be solved.

[0054] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0055] Figure 1 The following is a flow chart of a method for constructing a control system based on chemical synthesis provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0056] Step S110, obtaining chemical engineering design data.

[0057] As a possible implementation, the chemical engineering design data may be unit design data of chemical engineering.

[0058] Step S120, determining the instruction set of the controlled chemical unit according to the chemical engineering design data.

[0059] In this step, facing the unit design of chemical industry, the instruction set list of the related controlled units is defined. For example, the instruction set list can be shown in the following table:

[0060]

[0061]

[0062]

[0063] Step S130, constructing an initial chemical synthesis control system based on the operation control data corresponding to the instruction set, accessing module functions of the initial chemical synthesis control system based on the operation control data, and determining hardware topology data of the initial chemical synthesis control system according to the accessed module functions.

[0064] In practical applications, in order to be compatible with the operation control of the above chemical units, a chemical synthesis experiment control system is designed to access its module functions. Figure 2 As shown, it is an example of the hardware topology of a chemical synthesis experiment control system: the reaction has two reaction solvents, namely flask_s1 and flask_s2, flask_s1 and flask_s2 are pumped by a device combining a first plunger pump pump_solvents and a first multi-way valve valve_solvents, and the first multi-way valve valve_solvents is connected to the first waste liquid bottle waste_solvents; the reactor of the reaction is reactor_reactor, and the liquid is pumped by a device combining a second plunger pump pump_reactor and a second multi-way valve valve_reactor, and the second multi-way valve valve_reactor is connected to the second waste liquid bottle waste_reactor; the product container of the reaction is flask_product, and the liquid is pumped by a device combining a third plunger pump pump_product and a third multi-way valve valve_product, and the third valve_product is connected to the third waste liquid bottle waste_product.

[0065] Step S140, determining the control process data of the chemical synthesis execution system corresponding to the controlled chemical unit by the initial chemical synthesis control system.

[0066] like Figure 3As shown in the figure, the research and development needs of new molecules often need to start from chemical methods, conduct research such as reaction route design, experimental design, synthesis / characterization, and then organize the relevant design ideas into unit design in the chemical industry. The physical carrier of the unit design is the controlled physical unit, which has communication protocols such as TCP / IP, board driver, Modbus TCP, and electromechanical interfaces such as mechanical connection, electrical interface, pipeline interface, and communication interface. As a bridge between chemical methods and actual physical hardware, the chemical synthesis control system needs to realize the following functions: realize the automatic process control of chemical reactions (the above-mentioned control process data); drive the corresponding physical units to complete the corresponding functions. Through the reconstruction of the control system software and the recombination of hardware modules, the design of new control software instances and hardware system instances is completed to match the research and development needs of new molecules.

[0067] like Figure 4 As shown, it is the control flow of the chemical synthesis execution system corresponding to the chemical synthesis control system and the controlled chemical unit. The chemical synthesis control system in the embodiment of the present application can be a non-real-time system computer, and the program written in the control system can be a high-level language such as Python and C#. The chemical synthesis execution system can be a real-time system, such as an embedded system, PLC, etc., and the programming language can be C, IEC-61131-3, etc.

[0068] Step S150, constructing a target chemical synthesis control system based on the initial chemical synthesis control system using hardware topology data, operation control data and control process data.

[0069] In the embodiment of the present application, the instruction set of the controlled chemical unit is determined by chemical design data, and then the initial chemical synthesis control system is constructed based on the operation control data corresponding to the instruction set, so that the chemical synthesis control system can match and adapt to a variety of different chemical design data. Moreover, the hardware topology data of the initial chemical synthesis control system is determined according to the function of the connected module based on the operation control data, and then the hardware topology data, the operation control data corresponding to the instruction set, and the control process data of the chemical synthesis execution system corresponding to the controlled chemical unit are used to further construct the initial chemical synthesis control system, thereby obtaining a reconfigurable target chemical synthesis control system that can be oriented to batch reactions, realizing the design of an automated organic synthesis control system using a relatively standardized process and format, more flexibly, and at a relatively low cost, meeting the needs of flexible automated synthesis of different molecules in the laboratory research and development stage, so that the target chemical synthesis control system can match and adapt to a variety of different scenarios, and solving the technical problem that the existing chemical synthesis control system has a low degree of matching and adaptability to a variety of different scenarios.

[0070] The above steps are described in detail below.

[0071] In some embodiments, the execution content of the above-mentioned target chemical synthesis control system includes: parsing the hardware diagram describing the chemical synthesis execution system, obtaining the parsing results, and acquiring the node information of the corresponding chemical unit object and the contact data corresponding to the nodes of the chemical unit object based on the parsing results; parsing the chemical synthesis instruction set in the instruction set, distributing and processing the instructions in the chemical synthesis instruction set, and calling the corresponding communication interface for distribution and processing to drive the chemical synthesis execution system.

[0072] As an example, the chemical synthesis control system may include the following functions: to parse the hardware diagram describing the chemical synthesis execution system, obtain the corresponding chemical unit node information and the corresponding connection of the chemical node; parse the chemical synthesis instruction set, such as Figure 4 As shown, the instructions are distributed and processed, and the corresponding communication interface is called to drive the chemical synthesis execution system. The list of specific instructions in the above instruction set can be shown in the following table:

[0073]

[0074]

[0075]

[0076]

[0077]

[0078]

[0079] In the embodiments of the present application, through the execution content of the above-mentioned target chemical synthesis control system, the action objects of the chemical synthesis experiment control system (target chemical synthesis control system) are defined in view of the research and development needs of new molecules, so that the control effect of the target chemical synthesis control system on chemical synthesis is more precise.

[0080] In some embodiments, the chemical synthesis instructions in the chemical synthesis instruction set include at least one of serial instructions and parallel instructions; the chemical synthesis instructions are distinguished by S / P during design, and are parsed by traversing the instruction queue corresponding to the chemical synthesis instructions: if the prefix of the chemical synthesis instruction is S, it is determined to be a serial instruction, and is blocked from joining the existing thread pool; if the prefix of the chemical synthesis instruction is P, it is determined to be a parallel instruction, and a new thread is instantiated for scheduling.

[0081] In practical applications, such as Figure 4As shown in the figure, since chemical synthesis instructions may be serial instructions or parallel instructions, they can be distinguished by "S / P" when designing instructions. Traverse the instruction queue for parsing: if the instruction prefix is ​​"S", it is a serial instruction, and it is blocked from joining the existing thread pool; if the instruction prefix is ​​"P", it is a parallel instruction, and a new thread is instantiated for scheduling.

[0082] In an embodiment of the present application, by distinguishing serial instructions and parallel instructions in chemical synthesis instructions through S / P, serial instructions or parallel instructions can be distinguished more accurately, so that the process of blocking joining an existing thread pool or executing instantiation of a new thread for scheduling can be executed more accurately.

[0083] In some embodiments, the execution content of the above chemical synthesis execution system includes:

[0084] Determine the actions to be performed by the functional units of the chemical synthesis execution system based on the chemical synthesis instruction set, and encapsulate the chemical synthesis instruction set for the functional units based on the actions, and obtain the instruction interface through encapsulation; wherein a single chemical synthesis instruction set includes multiple steps and feedback;

[0085] Receiving a target instruction transmitted by a target chemical synthesis control system through a communication interface corresponding to the instruction interface, and executing the instruction according to the trigger of the target instruction;

[0086] If a fault occurs during the execution of an instruction, a fault warning is issued, and fault processing is performed according to the fault, and the execution status of the chemical synthesis execution system is reported.

[0087] As an example, Figure 4 As shown, the functions of the chemical synthesis execution system are as follows: first, define the actions required by the functional unit, and encapsulate the instruction set of the functional unit; a single instruction set may include multiple steps and feedback, which need to be encapsulated into an instruction interface; the communication interface accepts instructions from the chemical synthesis control system and triggers the instructions for execution; the chemical synthesis execution system has independent fault warning and processing functions, and can report its status to the outside.

[0088] In the embodiment of the present application, the instruction set of the chemical synthesis execution system is defined by the execution content of the above-mentioned chemical synthesis execution system, and the interaction relationship between the chemical synthesis experiment control system and the chemical synthesis execution system is also defined.

[0089] In some embodiments, the hardware topology structure of the hardware topology data includes: a first reaction solvent and a second reaction solvent for a target chemical reaction; the first reaction solvent and the second reaction solvent are pumped by a first combination device combining a first plunger pump and a first multi-way valve, and the first multi-way valve is connected to a first waste liquid bottle; the reactor of the target chemical reaction is pumped by a second combination device combining a second plunger pump and a second multi-way valve, and the second multi-way valve is connected to a second waste liquid bottle; the product container of the target chemical reaction is pumped by a third combination device combining a third plunger pump and a third multi-way valve, and the product container is connected to a third waste liquid bottle.

[0090] For example, a hardware topology example of a chemical synthesis experiment control system is as follows: Figure 2 As shown, the specific description of its structure is as follows: the reaction has two reaction solvents, namely flask_s1 and flask_s2, flask_s1 and flask_s2 are pumped by a device combining a first plunger pump pump_solvents and a first multi-way valve valve_solvents, and the first multi-way valve valve_solvents is connected to a first waste liquid bottle waste_solvents; the reactor of the reaction is reactor_reactor, and liquid pumping is performed by a device combining a second plunger pump pump_reactor and a second multi-way valve valve_reactor, and the second multi-way valve valve_reactor is connected to a second waste liquid bottle waste_reactor; the product container of the reaction is flask_product, and liquid pumping is performed by a device combining a third plunger pump pump_product and a third multi-way valve valve_product, and the third multi-way valve valve_product is connected to a third waste liquid bottle waste_product.

[0091] In the embodiment of the present application, the hardware topology design of the chemical synthesis execution system is more accurately defined through the hardware topology structure of the above-mentioned hardware topology data.

[0092] In some embodiments, the data format of the hardware topology data is in XML format, and the chemical unit objects corresponding to the hardware topology data are represented in the form of nodes in the hardware diagram, and the business connections between the chemical unit objects corresponding to the nodes are represented in the form of edges through directed arrows; wherein, the nodes are used to record the corresponding chemical unit attributes, and the edges are used to record the path associations of the corresponding nodes, and both the nodes and the edges can be parsed by reading XML through the program; the chemical unit attributes include at least one of the reagent bottle volume and the communication interface parameters of the valve pump.

[0093] In practical applications, the format of the hardware topology can be XML format, and the corresponding chemical unit objects are represented by rectangular "nodes" in the figure, such as Figure 2 As shown in the figure, the business connections between the corresponding chemical units are represented by "edges" with directed arrows. Among them, "nodes" can record the corresponding chemical unit attributes, such as the volume of reagent bottles, the communication interface parameters of valve pumps, etc., and "edges" can record the path associations of the corresponding nodes, which can be parsed by reading XML through the program, which not only defines the hardware topology design of the chemical synthesis execution system, but also improves the parsing efficiency of the hardware topology through program reading and parsing.

[0094] In some embodiments, the program structure of the target chemical synthesis control system includes an application client layer, a core business layer, an instruction execution layer, and a device driver layer; the new synthesis system is instantiated through the application client layer, and the application client layer is used to configure the file location of reading hardware topology data and instruction sets, and configure the location of the output log script;

[0095] The core business layer includes an instruction parsing module, a hardware parsing module, an instruction distribution module and a general module; the instruction parsing module is used to parse the text file of the instruction set, and convert the instructions in the instruction set into a queue by means of lexical analysis and / or syntax analysis; the hardware parsing module is used to parse the hardware diagram of the chemical synthesis execution system, obtain the node information of the corresponding chemical unit object, and the contact data corresponding to the nodes of the chemical unit object, so as to facilitate the mutual scheduling of instructions; the instruction distribution module is used to initialize the corresponding hardware diagram and instructions, and distribute the instructions of different functional units; the general module is used to define logs and global variables;

[0096] The instruction execution layer is used to distribute instructions based on Cmd_Exec, call the corresponding functional unit control class to implement the actual instruction set, and execute the derivation of the functional unit control class of the instruction execution layer to simulate and output the corresponding information;

[0097] The device driver layer is used to schedule the instruction set of the functional unit control class based on the instruction execution layer to call the interface corresponding to the hardware device to complete the protocol and drive the hardware device.

[0098] For example, Figure 5 and Figure 6 As shown in the figure, the software structure and corresponding execution process of the chemical synthesis control system are described. The software can be divided into the following four layers from top to bottom:

[0099] The first layer is the application client, which instantiates the new synthesis system, configures the file location of the hardware topology and instruction set files, and configures the location of the output log script.

[0100] The second layer is the core business layer, which includes the following four modules: ① The function of the instruction parsing module is to parse the instruction set text file and convert the instructions into queues, which can generally be achieved through lexical analysis (such as Lex) and syntax analysis (such as Yacc); ② The function of the hardware parsing module is to obtain the hardware diagram of the chemical synthesis execution system, obtain the corresponding chemical unit node information, and the connection between the nodes, so as to facilitate the mutual scheduling of instructions; ③ The instruction distribution module initializes the corresponding hardware diagram and instructions, and distributes the instructions of different functional units; ④ Other common modules are the definitions of logs, global variables, etc.

[0101] The third layer is the instruction execution layer, which has the following functions: based on the instruction distribution of Cmd_Exec, call the corresponding functional unit control class to implement the actual instruction set, such as Pump_Exec, Vavle_Exec, Stirrer_Exec and other functional unit control classes. In addition, by deriving the specific instruction execution layer functional unit control class in this functional layer, the corresponding information can be output purely by simulation.

[0102] The fourth layer is the device driver layer, whose functions are as follows: based on the instruction set scheduling of the functional unit control class of the instruction execution layer, calling the corresponding interface of the hardware device to complete specific protocols and drivers, such as Pump_api, Vavle_api, Stirrer_api and other device driver classes.

[0103] In the embodiment of the present application, the control software architecture of the chemical synthesis experiment control system is more accurately defined through the above four-layer chemical synthesis control system software structure, making the software control process of the chemical synthesis experiment control system more accurate.
