Referring to fig. 2, fig. 2 is a flowchart illustrating a method for transmitting information in a laser system according to an embodiment of the present application, which provides a method for transmitting information in a laser system constructed by a desktop-level laser device.

Firstly, on the hardware structure of the desktop-level laser equipment, a plurality of controllers are distributed on the realized laser system, and the service functions of the laser system are realized through the mutual coordination among the controllers.

The mutual coordination among the controllers comprises the information circulation among the controllers and the response to the circulated information, and further the corresponding controllers analyze and process the obtained instructions under the control of the circulated information.

The controller includes a main control board card, a motion control board card connected with the main control board card, and other board cards connected with the motion control board card, so that service functions of the laser system are executed under the action and cooperation of different controllers.

The information transmission method in the laser system shown in fig. 2 is deployed on several controllers as an execution of the communication process in the laser system, and processes the information flow between the controllers.

The information transmission method in the laser system comprises the following steps:

Step S210, responding to the service function trigger of the laser system, the main control board card generates instruction data, and the instruction data is used for executing the service function of the laser system by the corresponding controller;

step S220, data distribution is carried out on the main control board card through a communication protocol with the adaptive command data, wherein the communication protocol is from a plurality of communication protocols supported between the main control board card and the motion control board card;

step S230, the motion control board card obtains distributed instruction data through an interface bound by the motion control board card;

step S240, obtaining address information corresponding to a controller for analyzing and processing the instruction data through unpacking and reading related to the instruction data;

and step S250, analyzing and processing the instruction data in the corresponding controller according to the address information.

These steps are described in detail below.

In step S210, it should be first explained that, for the laser system constructed by the desktop-level laser device, the service functions thereof will include, but are not limited to: firmware upgrade, camera mapping, file uploading and downloading, system configuration, processing control, debugging and machine state reporting. Different service functions are adapted to different service scenes to realize the operation of the laser system, for example, under factory debugging scenes of a factory, and each generated debugging instruction completes the processing of debugging service through the execution of the communication process of the application.

Triggering service functions on the laser system, so that the master control board card responds to the triggered service to generate instruction data. The triggering of service functions on the laser system, including the triggering of function keys on the desktop level laser device, and the driving of laser processing programs running in a directly connected or network connected host computer, such as a PC, mobile terminal, are not limited herein.

The main control board card is linked with function keys and an upper computer distributed on the desktop laser equipment, and responds to generate instruction data along with the triggering of the service function, and other controllers are controlled to execute corresponding operations through the instruction data distribution executed on the main control board card, so that the triggered service function is achieved.

Based on the above, the main control board card is controlled by the triggering of the service function to generate instruction data for controlling the main control board card and other controllers.

The generated instruction data is adapted to the triggered service function, and may be an instruction corresponding to the firmware upgrade file, a G code, an M code, or a peripheral control instruction in a data form.

Corresponding instruction data are generated by a main control board card for controlling the business processing of the main control board card and the business processing processes of other controllers.

In step S220, the main control board card performs data distribution on the generated instruction data so as to enable the instruction data to be transmitted to a controller capable of analyzing and processing the instruction through the progress of data distribution.

It should be noted that, the data distribution executed by the main control board card includes a process of packaging and transmitting instruction data, which is different from a process of analyzing and processing instruction data performed by the main control board card itself. For the instruction data which belongs to the main control board card and needs to be processed, the data distribution is not executed, and the analysis and processing process is executed on the instruction data so as to complete the business processing on the main control board card. The analysis and processing of the instruction data are the process of analyzing the instruction data into executable data form and further executing corresponding operation according to the analyzed instruction, which is different from the data distribution process executed by other controllers.

The controller in the laser system is used for coupling the data distribution with the instruction data analysis position, the business processing of the controller is independent of the data distribution performed by the controller, the data distribution performed by the controller to other controllers is performed, the instruction data generated by the main control board card but required to be executed by the other controllers can be transmitted to the controller to which the instruction data belongs, namely the target controller, by the main control board card, and therefore the performance of the business processing and the orderly performance of the data distribution are guaranteed, and interference among the business processing and the data distribution cannot be generated.

Therefore, the data distribution and the business processing performed by the main control board card are independent and do not interfere with each other. In data distribution, the main control board card is preconfigured with a plurality of communication protocols, and the packaging and the transmission of instruction data are controlled through the combination of any one of the communication protocols and a plurality of the communication protocols, so that the instruction data with different service functions are adapted, and the purpose of adapting to different service scenes is achieved.

Specifically, the communication protocol configured by the main control board card includes a direct connection transmission protocol for controlling direct transmission of instruction data, an address encapsulation protocol for indicating an address for transmission of the instruction data to the target controller and encapsulating the instruction data, a reliability transmission protocol for ensuring reliable transmission of the instruction data, and a frame protocol for encapsulating protocol packets into frames. For the communication from the main control board card to the motion control board card, the instruction data is packaged and transmitted according to different communication protocols or communication protocol combinations which are adapted to different instruction data.

Furthermore, for the mutual adaptation between the instruction data and the communication protocol, the service function corresponding to the instruction data can be predefined and configured, and under the predefined and configured condition, the main control board card can adapt to a single communication protocol or a communication protocol combination according to the service function corresponding to the generated instruction data and the service scene.

For example, the instruction data generated by the triggering of the debugging service triggered under the factory debugging scene can be applicable to a protocol for controlling direct transmission of the instruction data, and the debugging can be completed rapidly and efficiently through the direct transmission.

For example, the user triggers the laser cutting function through the upper computer under the processing scene of the user, the upper computer controls the generation of G codes, and the G codes are transmitted to the motion control board card by the main control board card as instruction data, so that the production jig, such as a cutter head, can move and cut under the control of the G codes.

For another example, the controller distributed in the laser system may further include a water-cooling control board, and the laser system triggers the instruction data generated by the water-cooling function to be transmitted to the water-cooling control board by the main control board, the motion control board, and the like. The main control board card responds to instruction data generated by triggering of the water cooling function, firstly, a protocol for transmitting instruction addresses to the target controller and packaging the instruction data is adapted, then, after a packet header is added through a reliability transmission protocol, the protocol packet is packaged into frames, and finally, the frames are transmitted to the motion control board card under the control of the reliability transmission protocol, so that the reliability and the efficiency of subsequent forwarding are ensured.

Of course, it should be understood that the instruction data may also be encapsulated and transferred using only the protocol that indicates the address for transfer of the instruction data to the target controller and encapsulates the instruction data (i.e., the address encapsulation protocol), or other non-enumerated combinations of communication protocols may be employed, and are not limited and listed herein.

In summary, a plurality of communication protocols are supported between the main control board card and the motion control board card to adapt to instruction data corresponding to different service functions and service scenes, so that rich communication protocols are provided for realizing different service scenes, the communication flexibility is ensured, and the communication performance of the laser system is greatly improved.

After the main control board card generates instruction data, the data distribution process is executed through the adapted communication protocol for the instruction data which does not belong to the main control board card, namely the instruction data which does not need to be executed by the main control board card to complete the corresponding business processing process, so as to transmit the instruction controller to the target controller.

Referring also to fig. 3, fig. 3 is a flowchart illustrating a method for transmitting information in a laser system according to another embodiment of the present application, where the embodiment of the present application provides a method for transmitting information in a laser system.

In this embodiment, the step S220 of performing data distribution by using the communication protocol adapted to the instruction data on the main control board card may include:

step S221, the main control board dynamically switches the communication protocol configured by the main control board for transmitting the instruction data, wherein the communication protocol is designated by the instruction data;

step S222, packaging instruction data through the switched communication protocol to obtain a data unit carrying the instruction data;

step S223, sending the data unit to the motion control board card through the interface to which the instruction data is associated.

These steps are described in detail below.

In step S221, as indicated in the foregoing description, a plurality of communication protocols are supported between the main control board card and the motion control board card, so that the data transfer performed can select a more applicable communication protocol.

The main control board card selects a communication protocol for the instruction data by switching the communication protocol, and the selected communication protocol is specified by the instruction data. In other words, the instruction data designates the communication protocol, and the adapted communication protocol can be designated by the service function corresponding to the instruction data.

And the main control board card dynamically switches the communication protocol configured by the main control board card along with the different generated instruction data to obtain the currently-adapted communication protocol. Exemplary communication protocols specified by the instruction data include an address encapsulation protocol, a direct transfer protocol, a reliability transfer protocol, a combination of two protocols of a frame protocol, and a combination of three protocols of the address encapsulation protocol, the reliability transfer protocol, and the frame protocol.

In step S222, under the control of the dynamically switched communication protocol, the encapsulation of the instruction data is performed first, so as to obtain a data unit carrying the instruction data. According to different communication protocols, different encapsulation processes are carried out on the instruction data, and corresponding to the encapsulation processes, the obtained data unit carrying the instruction data comprises a frame of data formed by a network layer, a reliability transmission protocol packet formed by a transmission layer and a data frame in a data form.

As described above, the encapsulation of the instruction data adapts to different communication protocols, and the execution process is different.

Illustratively, under the control of an address encapsulation protocol, the instruction data is taken as original data, and address information of the target controller is added and encapsulated to obtain a frame of data; at this time, the frame data obtained by encapsulation can be directly transmitted to the motion control board card, or can be encapsulated layer by a reliability transmission protocol and a frame protocol, and finally the frame data is obtained and transmitted. Of course, for the encapsulation of the instruction data, the frame data can also be obtained directly under the control of the reliability transmission protocol and the frame protocol, and transmitted to the motion control board card.

Referring also to fig. 4, fig. 4 is a flowchart illustrating steps for encapsulating command data by switching a communication protocol to obtain a data unit carrying the command data according to one embodiment of the present application. The embodiment of the present application provides the step S222 of encapsulating the instruction data by using the switched communication protocol to obtain the data unit carrying the instruction data, which may include:

Step S301, generating address information according to a controller mapped by instruction data;

in step S302, the address information and the instruction data are encapsulated with the defined header identifier and the tail identifier, so as to obtain a frame of data, where the frame of data is a data unit carrying the instruction data.

These two steps are described in detail below.

In step S301, as described above, each instruction data is assigned to a controller, and the controller actually parses and processes the instruction data, so that each instruction data has a mapping relationship with a controller based on the service function to which it belongs. In the execution of step S301, address information is generated according to the mapping relationship between the service function to which the instruction data belongs and the controller, where the address information indicates the target controller to which the instruction data is finally transferred.

In step S302, the address encapsulation protocol defines a header identifier and a trailer identifier that are used, for example, the header identifier may be F0, and the trailer identifier corresponding thereto may be F7, which is not limited herein. The packet header identifier and the packet tail identifier are used for indicating which data are attributed to one protocol for continuous data transmission by the laser system, for example, the packet header identifier is F0, and the packet tail identifier is F7, which is necessarily attributed to the address encapsulation protocol of F0F7, so as to ensure the integrity and reliability of the protocol packet.

After the address information of the target controller is obtained, the address information and the instruction data are encapsulated together using the packet header identifier and the packet tail identifier to obtain one frame of data, at which time the frame of data will be the data unit carrying the instruction data.

Referring also to fig. 5, fig. 5 is a flowchart illustrating steps for encapsulating command data by switching a communication protocol to obtain a data unit carrying the command data according to one embodiment of the present application. The embodiment of the application introduces a reliability transmission protocol for the encapsulation of the instruction data, so that for the communication of the laser system, the instruction data can be directly transmitted to the motion control board card by using the reliability transmission protocol and the frame protocol on the one hand, and on the other hand, the encapsulation of the instruction data can be realized by introducing the reliability transmission protocol and the frame protocol on the basis of the address encapsulation protocol, namely combining the embodiment corresponding to fig. 4, and the transmission of the instruction data is executed under the control of the reliability transmission protocol.

The embodiment of the present application provides the step S222 of encapsulating the instruction data by the switched communication level to obtain the data unit carrying the instruction data, which may include:

Step S401, carrying out reliability encapsulation on instruction data or obtained frame data to obtain a reliability transmission protocol packet;

in step S402, the reliability protocol packet is encapsulated into a transport layer frame to obtain a data frame as a data unit.

These two steps are described in detail below.

In step S401, for encapsulation framing performed by the transport layer, it is encapsulated as raw data of a frame, which may be instruction data, or one frame of data encapsulated by the network layer via an address encapsulation protocol.

For the transmission realization in a laser system, the instruction data can be directly used as the original data of the reliability package, and the package is a reliability transmission protocol package, so that the reliability of the instruction data transmission is ensured, the reliability and the speed are enhanced for the transmission between a main control board card and a motion control board card, and the transmission of the instruction data is fast and reliable on the premise that the sequential operation of the laser system is ensured under the condition that the target controller is the motion control board card.

Thus, after the instruction data is used as the original data and the reliability package is directly performed to obtain the reliability transport protocol packet, the reliability transport protocol packet can be packaged into a frame through step S402 under the control of the frame protocol.

On the other hand, under the combination of the address encapsulation protocol, the reliability transfer protocol, and the frame protocol, the reliability encapsulation process performs reliability encapsulation with respect to one frame of data obtained under the control of the address encapsulation protocol.

Reliability encapsulation, whether performed on instruction data or a frame of data, is a process of adding a Header (Kcp Header) to data to be transmitted.

In step S402, the reliable transport protocol packet at the transport layer is encapsulated into a frame using a frame protocol to obtain a data frame, and the data frame is thus a data unit carrying instruction data.

In step S230, along with the data distribution executed by the main control board card on the instruction data, the motion control board card connected to the main control board card obtains the instruction data distributed by the main control board card through the self-binding interface.

The motion control board card and the main control board card are connected through a set interface. By way of example, the interface may be a USB serial port, a UART serial port, a Bluetooth interface, a WiFi interface, etc., without limitation.

The interfaces between the main control board card and the motion control board card are rich. And the interface for transmitting the instruction data is bound between the main control board card and the motion control board card. Correspondingly, the interface of the motion control board card for obtaining the instruction data is bound by the motion control board card adapting to the instruction data. Interface binding carried out by adapting instruction data can be specifically realized according to a communication protocol to which the instruction data is adapted, and can also be realized according to a target controller binding interface corresponding to the instruction data, no matter what binding relation is established, the interface binding is realized based on the corresponding relation between the instruction data and the communication protocol, and between the instruction data and the controller.

The master control board card is adapted to command data for transmission to the motion control board card via the bound interface, in particular transmission over the bound interface may be performed under control of a reliability transfer protocol. The interface of the motion control board card receives instruction data encapsulated by a transmission layer, such as a reliability transmission protocol packet, or a frame of data which is added with address information and encapsulated by a specific packet head identifier and a packet tail identifier at a network layer, and can also receive a data frame obtained by sequential encapsulation of the network layer and the transmission layer.

In step S240, the motion control board performs unpacking related to the instruction data through the execution of step S240, and reads address information from the unpacked data, where the address information is used to indicate a target controller of the instruction data, and the target controller is used to parse and process the instruction data to implement service processing, for example, the aforementioned G code that is used by the host computer to implement motion and cutting control on the laser system, and the target controller is the motion control board.

The address information may be, for example, a device identification of the target controller. The address information corresponding to the instruction data transmission can be obtained through the unpacking in step S240, and the address information will be added to the original instruction data in the process of packaging the instruction data, which is the process of packaging the instruction data.

For the motion control board, the read address information is used for indicating whether the instruction data is analyzed and processed by the motion control board or needs to be forwarded to other controllers, so that the unpacking and business processing processes of the motion control board can be decoupled under the action of the address information, the situation that the instruction data cannot be processed after analysis is not found any more, the business processing efficiency is greatly improved, and the system consumption is reduced.

Unpacking executed by the motion control board corresponds to instruction data encapsulation executed by the main control board, and the unpacking and the instruction data encapsulation are applicable to the same communication protocol.

Referring also to fig. 6, fig. 6 shows a flow chart of a method of information transmission in a laser system according to another embodiment of the present application. The embodiment of the application realizes the unpacking of the received frame data under the address encapsulation protocol.

Specifically, the step S240 of obtaining address information corresponding to the controller for parsing the processing instruction data through unpacking and reading related to the instruction data may include the following steps:

step S241a, discarding the packet header identifier and the packet tail identifier in the received frame data to obtain data fragments;

in step S242a, address information corresponding to the controller for analyzing the processing instruction data is read from the data fragment.

These two steps are described in detail below.

In step S241a, with the data transmission by the main control board, the motion control board receives one frame of frame data, and performs parsing on each frame of data to read address information therefrom.

As indicated above, the main control board card under the control of the address encapsulation protocol obtains a frame of data by adding address information to the instruction data and encapsulating the packet header identifier and the packet tail identifier; in response thereto, after the motion control board card receives a frame data, for the frame data, a data fragment including address information and instruction data is first obtained by discarding the packet header identifier and the packet tail identifier.

Under the control of the address encapsulation protocol, the data to be transmitted, i.e. the instruction data, is divided into a plurality of data fragments, i.e. data segments, and then the data fragments obtained by unpacking the data fragments comprise the address information and the instruction data, wherein the frame data is obtained by executing the package with the address information, the packet header identifier and the packet tail identifier.

In step S242a, the address information carried by the data slice is read, and the address information indicates the corresponding instruction data, that is, the instruction data carried in the data slice, to be transferred to the target controller.

Further, referring to fig. 7, fig. 7 is a flowchart illustrating steps for obtaining address information corresponding to a controller for parsing instruction data by unpacking and reading the instruction data according to the embodiment shown in fig. 5. As the encapsulation of packets proceeds under the control of the reliability transfer protocol and frame protocol shown in fig. 5, the embodiments of the present application will perform a corresponding unpacking process.

The step S240 of obtaining address information corresponding to the controller for parsing the processing instruction data through unpacking and reading related to the instruction data provided in the embodiment of the present application may include:

step S241b, discarding the frame head and frame tail of the received data frame to obtain a reliability transmission protocol packet;

step S242b, unpacking the reliability transmission protocol packet to obtain a frame of data;

step S243b, reads address information and command data corresponding to the controller for analyzing the processing command data from the frame data.

These steps are described in detail below.

In step S241b, the motion control board receives the data frame transmitted by the main control board, and first discards the frame header and the frame tail of the data frame, thereby obtaining the encapsulated reliability transport protocol packet.

In step S242b, the packet Header (Kcp Header) is discarded for the reliability transmission protocol during the unpacking process to obtain frame data, i.e. a frame data obtained by encapsulating the defined packet Header identifier, packet tail identifier and address information by the main control board card under the control of the address encapsulation protocol.

In step S243b, as described above, the frame data includes, but is not limited to, the header identifier, the address information, the instruction data, and the trailer identifier in the data format, and thus the motion control board card reads the address information and the instruction data from the parsed frame data. The read address information is used for indicating a target controller to which the instruction data is finally transmitted, and the instruction data is used for enabling the target controller to complete corresponding service processing so as to achieve a triggered service function.

That is, as the motion control board card receives, unpacks and reads the main control board card, address information and instruction data are obtained, and the address information and the instruction data are associated with each other. For the motion control board card, it is possible to first know which controller the instruction data needs to be processed by, based on the address information.

If the instruction data is processed by the motion control board, the motion control board analyzes and processes the instruction data. If the instruction data is not processed by the motion control board, the motion control board forwards the instruction data, and analysis and processing of the instruction data are not performed, so that the instruction data do not consume system resources of the motion control board.

In step S250, the motion control board obtains the address information corresponding to the instruction data through the execution of step S240, so that the parsing and processing process of the instruction data on the controller corresponding to the address information can be initiated, and further the business processing is completed.

It should be noted that, the initiation of the instruction data parsing and processing procedure includes, according to the difference of the address information: the instruction data is executed at the initiation of the motion control board card, i.e. the parsing and processing procedure, and the forwarding of the instruction data to other controllers, even the parsing and processing procedure on the controller to which it is forwarded.

Specifically, if the address information corresponds to the motion control board, the instruction data transmitted together with the address information is analyzed and processed by the motion control board, and the corresponding service is the service function of the motion control board, and at the moment, the analysis and the processing of the instruction data are only required to be initiated on the motion control board; if the address information corresponds to other controllers, such as a water-cooled control board card connected to a motion control board card, forwarding of the address information and instruction data is required to enable the address information and instruction data to be transferred to the corresponding controller.

After the address information and the instruction data are transmitted to the corresponding controller, the controller unpacks and reads the address information, and then knows that the instruction data can be resolved and processed by itself, so that the resolution and processing of the execution instruction data are initiated.

And the like, at least one forwarding of the motion control board card to the target controller can be completed until the instruction data is finally analyzed and processed.

Through the above exemplary embodiments, it can be seen that the communication mechanism is constructed so that the distribution of instruction data can be completely decoupled from service processing, thereby saving system resources and greatly improving service processing efficiency.

And by the above-mentioned exemplary embodiments, a rich communication protocol is provided for the laser system, so as to meet various service requirements.

Referring also to fig. 8, fig. 8 shows a flow chart of a method of information transmission in a laser system according to another embodiment of the present application. The step S250 of initiating the analysis and processing of the instruction data in the corresponding controller according to the address information provided in the embodiment of the present application may include:

step S251, it is determined whether the address information matches the own address, if not, step S252 is executed, and if yes, step S253 is executed.

Step S252, the forwarding process of the instruction data is performed according to the address information.

Step S253, parse and process the instruction data.

These steps are described in detail below.

In step S251, the controller that receives the data unit carrying the instruction data may be a motion control unit or another controller. Whether the address information obtained by unpacking and reading is consistent with the address of the controller is judged by any controller, if the address information obtained by unpacking and reading is inconsistent with the address of the controller, the controller is not the controller for processing the instruction data, and the controller is only the intermediate controller for transmitting the instruction data to the target controller.

The controller's own address, which is in the form of a device identification, is adapted to the address information. The controller judges the consistency of the addresses of the received instruction data, so that the situation that the instruction data is directly analyzed and processed in the existing laser system, and the instruction data is not attributed to the controller and is forwarded to other controllers is avoided until the instruction data cannot be processed.

If the address information does not coincide with the controller' S own address, the instruction data is forwarded according to the address information in the execution of step S252.

The forwarding of command data may occur in the motion control board card as well as in other controllers. Illustratively, the forwarding of instruction data is accomplished under control of an address encapsulation protocol.

In particular, referring also to fig. 9, fig. 9 shows a flow chart of the forwarding processing steps of executing instruction data according to address information according to the disclosed embodiment of fig. 8. In the transmission of instruction data under the control of a reliability transmission protocol and a frame protocol or under the control of a direct connection transmission protocol, the unpacking results in the original data, namely the instruction data itself.

At this time, the forwarding process of the instruction data is performed with respect to the instruction data itself, and the protocol used for forwarding is the address encapsulation protocol, so that the instruction data encapsulation under the control of the address encapsulation protocol needs to be performed again to obtain and forward a frame of data.

As shown in fig. 9, the embodiment of the present application provides a step S252 of performing forwarding processing of instruction data according to address information, which may include:

step S2521, encapsulating address information and instruction data with the defined packet header identifier and packet tail identifier again to obtain a frame of data carrying the instruction data;

In step S2522, the frame data is forwarded to the corresponding controller through the interface mapped with the address information.

These two steps are described in detail below.

In step S2521, for forwarding the instruction data, address information is first added to the instruction data, and encapsulated with a header identifier and a trailer identifier defined by an address encapsulation protocol, so as to obtain a frame of data, and then forwarded to a corresponding controller through the interface mapped according to the address information by the execution of step S2522.

The mapping of the address information to the interface may be, as noted above, an interface to which the corresponding instruction data belongs to a service function map, or may be an interface to which a controller that processes the instruction data maps, and is not limited herein.

On the other hand, in the transmission of instruction data implemented under the control of the address encapsulation protocol and the reliability transmission protocol, the step S252 of receiving a data frame carrying instruction data and unpacking to obtain a frame of data, which correspondingly provides the execution of the forwarding process of the instruction data according to the address information, may include:

and forwarding the frame data obtained by unpacking to the corresponding controller by an interface adapting to the address information mapping.

Under the control of the address encapsulation protocol, one frame of data obtained by the frame data unpacking still has the packet head identifier, the packet tail identifier and the address information, which are not only the existence of the complete data packet, but also the address designated for the subsequent transmission, so that the frame data can be directly forwarded without any processing, and the communication performance of a laser system is greatly enhanced.

The following describes the circulation process from the main control board card to the motion control board card, even to other controllers in the laser system by taking the information transmission under each service function of the laser system supporting the direct connection transmission protocol, the address encapsulation protocol, the reliability transmission protocol and the frame protocol as an example.

First, referring to fig. 10, fig. 10 shows a hardware topology diagram related to a desktop level laser device according to an embodiment of the present application. The desktop level laser device can realize data interaction with an upper computer, such as a PC end and a mobile end, through an interface or a network, so that the upper computer can control the desktop level laser device and provide required resources for the desktop level laser device, such as realizing data interaction with the PC end and the mobile end erected at a far end under the support of realizing cloud service.

In the desktop-level laser device, as described above, the main control board card may be connected to the upper computer through a USB interface, or may be connected to the motion control board card through a configured interface, such as a USB interface, a UART interface, etc., and on this basis, the various controllers, i.e., the peripheral MCU1 and the peripheral MCU2, are also connected to the motion control board card, so that the transmission of respective instruction data is realized through the communications implemented in the embodiments of the present application, and further, the service processing is completed.

Referring also to fig. 11, fig. 11 shows a controller topology and a data flow diagram according to an embodiment of the present application. The laser system carried by the laser equipment structurally comprises a main control board card, a motion control board card connected with the main control board card and other controllers.

The other controllers are connected in parallel or in series with the motion control board card and receive instruction data transmitted by the main control board card and sent by the motion control board card.

The following describes the communication mechanism in the laser system according to different service functions.

(1) The triggered service function is a laser cutting function under a user processing scene, and in a laser system realized by the laser equipment, the main control board card completes the encapsulation of instruction data by combining a G code file reliability transmission protocol and a frame protocol and transmits the instruction data to the motion control board card.

Under the action of a reliability transmission protocol, the reliability of instruction data transmission is ensured between the main control board card and the motion control board card, so that the reliability of laser cutting control is ensured, and a high-reliability laser cutting function is realized.

Of course, it should be noted that the G code may also use a combination of an address encapsulation protocol, a reliability transmission protocol, and a frame protocol, so as to ensure that data distribution required by the G code can be implemented following address information under the action of the address encapsulation protocol, and ensure the order of system operation.

(2) The service function of the laser device debugging can be realized by supporting a direct connection transmission protocol (Raw), and besides, the instruction data can be encapsulated and transmitted under the action of an address encapsulation protocol, which is not limited herein.

So far, it can be seen that different types of instruction data correspond to different service functions. Thus, based on the difference of service functions, different instruction data are mapped with different interfaces. Referring also to fig. 12, fig. 12 is a schematic diagram illustrating mapping between a communication protocol and an interface according to an embodiment of the present application. The reliability transmission protocol (Kcp) is mapped with the USB interface, the address encapsulation protocol (F0F 7) is mapped with the USB interface and the serial port, and the direct connection transmission protocol (Raw) has mapping relation with the USB interface and the serial port.

The communication realized by the address encapsulation protocol, the reliability transmission protocol and the frame protocol combination is described in detail by taking the instruction data formed by the G codes as an original instruction.

Referring also to fig. 13, fig. 13 is a schematic diagram illustrating a data format implemented by combining an address encapsulation protocol, a reliability transmission protocol, and a frame protocol in an embodiment of the present application. The address encapsulation protocol and the reliability transmission protocol are configured in the network layer, the frame protocol is configured in the transmission layer, at this time, the instruction data which is the original instruction and exists in the protocol layer is added with address information through the address encapsulation protocol configured in the network layer, and F0 is used as a header identifier, F7 is used as a tail identifier for encapsulation, so as to obtain a frame of data.

The frame data uses the Kcp protocol as a reliable transmission protocol in a transmission layer to ensure the reliable transmission of instruction data and address information, and retransmission in abnormal conditions is completed, so that efficient and reliable transmission is realized for a laser system.

The resulting reliable transport protocol packet will be introduced with the frame concept and will be distinguished from the header identifier and the trailer identifier by escape means for intermediate data.

Referring also to fig. 14, fig. 14 shows a schematic diagram of G code transmission formats only existing between the main control board card and the motion control board card in the embodiment of the present application.

For G codes (Gcode) transmitted only between the main control board card and the motion control board card, it can be used to realize process control. In contrast, the G code is used as an original command only, and the transmission of the G code is performed by encapsulating and framing the Kcp protocol in the transmission layer. Similarly, the same applies to Mcode.
