[0002] In the field of plasma technology, arc ignition control system is one of the key technologies to achieve efficient and stable plasma generation. Existing plasma arc ignition control systems usually rely on fixed communication links and synchronization mechanisms to coordinate the actions of various control units, but these systems often lack effective countermeasures when facing communication link failures or interruptions. Once there is a problem with the communication link, the stability and reliability of the entire system will be affected, resulting in failure or reduced efficiency of the arc ignition process.

[0048] Reference below Figure 1 , Figure 1 The schematic diagram of the structure of a linear plasma arc ignition control system provided by one embodiment of the present invention. Figure 1 As shown, a linear plasma arc ignition control system 100 includes:

[0049] A plasma control unit set and two arc ignition control communication interfaces; wherein the plasma control unit set includes: a plurality of plasma control units connected in sequence through a communication link to form an arc ignition plate assembly line; the two arc ignition control communication interfaces are respectively connected to the plasma control units at the ends of the arc ignition plate assembly line; when the communication link between the plasma control units is disconnected, the plasma control unit at the end of the arc ignition plate assembly line shields the start signal sent by the arc ignition control communication interface connected thereto, and the disconnection includes one end of the plurality of plasma control units to form a dynamic network to control the linear plasma arc ignition to perform group actions; the plasma control unit at the end is used to generate a start signal, transmit the start signal to the plasma control unit at the end of the dynamic network, and the plasma control unit returns a response signal corresponding to the start signal to the corresponding plasma control unit at the end to control the linear plasma arc ignition on the arc ignition plate assembly line to perform group actions;

[0050] The linear plasma arc ignition control system also includes a central control switching device and two node switching devices;

[0051] The two node switching devices are respectively connected to the plasma control units at the ends of the arc-starting plate assembly line, and the two node switching devices are both connected to the central control switching device, which is used to connect to the host computer server; the central control switching device is used to receive the dynamic network instructions issued by the host computer server, and send the dynamic network instructions to the node switching device, and the node switching device sends the dynamic network instructions to one end of the disconnection point that includes multiple plasma control units, and the plasma control units at this end form a dynamic network according to the dynamic network instructions.

[0052] It should be noted that the linear plasma arc ignition control system is designed to be highly modular and flexible. Through the configuration of a plasma control unit set and two arc ignition control communication interfaces, effective control of the arc ignition plate assembly line is achieved. The plasma control unit set consists of multiple units, which are connected in sequence through a communication link to form a continuous control sequence, ensuring the synchronization and consistency of the arc ignition process. When the communication link is disconnected, the plasma control unit at the end can automatically shield the start signal and reorganize the control unit through a dynamic network to maintain the stable operation of the system.

[0053] Specifically, the plasma control unit can be a specially designed electronic module with the functions of signal reception, processing and transmission. The communication link can be a wireless or wired connection method, which is selected according to the actual application scenario and needs. The arc control communication interface is responsible for the connection with the plasma control unit and the transmission of signals. In the case of a disconnection of the communication link, the plasma control unit at the end can identify the disconnection position through the built-in logic judgment mechanism, and use the preset communication protocol to quickly form a dynamic network with other units to realize group action control on the arc plate assembly line.

[0054] Preferably, the plasma control unit can set different parameters, such as signal strength, processing time, etc., according to the actual arc striking requirements to adapt to different working environments. For example, under high load or high interference working conditions, the signal strength can be increased and the processing time can be extended to ensure accurate transmission and processing of the signal. More specifically, the formation of a dynamic network can be achieved through a central control algorithm, which can dynamically adjust the network structure and optimize the signal transmission path according to the number and position of the plasma control units included in the disconnection, thereby improving the response speed and arc striking efficiency of the system. In addition, a backup communication link or a redundant control unit can also be designed to further improve the reliability and fault tolerance of the system.

[0055] In some embodiments, the bidirectional digital communication interface unit includes: a signal driving module and a high-speed comparison module connected to the signal driving module;

[0056] The signal driving module and the high-speed comparison module are both connected to the first logic processing unit, the signal driving module is connected to an adjacent plasma control unit or an arc ignition control communication interface, and the high-speed comparison module is connected to an adjacent plasma control unit or an arc ignition control communication interface;

[0057] A high-speed comparison module of a bidirectional digital communication interface unit on one side of a plasma control unit at the end of the dynamic network is used to receive a start signal sent by a signal driving module of an adjacent plasma control unit, and send the start signal to a first logic processing unit of the plasma control unit;

[0058] The signal driving module of the bidirectional digital communication interface unit on the other side of the plasma control unit at the end of the dynamic network is used to receive the start signal sent by the first logic processing unit, and send the start signal to the high-speed comparison module of the bidirectional digital communication interface unit, and the high-speed comparison module returns the start signal to the first logic processing unit of the plasma control unit.

[0059] It should be noted that the bidirectional digital communication interface unit of the linear plasma arc ignition control system is designed to include a signal driver module and a high-speed comparison module, which work together to achieve fast and accurate signal processing. The signal driver module is responsible for generating and sending start signals, while the high-speed comparison module receives these signals and performs rapid comparisons to ensure the accuracy and timeliness of the signals. This design allows the system to respond quickly and process signal changes when transmitting signals between plasma control units, thereby improving the response speed and stability of the entire system.

[0060] Specifically, the signal driving module can be an electronic circuit that generates a start signal according to preset logic and parameters. These parameters include the frequency, amplitude and duration of the signal, etc., which can be adjusted according to different application scenarios. The high-speed comparison module is a high-precision electronic component that can compare and analyze the received signals in a short time to ensure the synchronization and consistency of the signals. Both modules are connected to the first logic processing unit, which is responsible for coordinating the work of the signal driving module and the high-speed comparison module, as well as communicating with the adjacent plasma control unit or arc ignition control communication interface.

[0061] Preferably, the design of the signal driving module and the high-speed comparison module can be further optimized to adapt to different working environments and performance requirements. For example, more efficient power management technology can be used to reduce energy consumption, or more advanced materials and technologies can be used to improve the transmission rate and stability of the signal. More specifically, an adjustable gain control can be set for the signal driving module to maintain the best signal quality under different signal strengths. At the same time, the high-speed comparison module can be designed to have a multi-level comparison function to achieve more sophisticated signal analysis and processing. In addition, it is also possible to consider introducing an adaptive filter or algorithm to automatically adjust the signal processing parameters and optimize the performance of the system under different working conditions.

[0062] In some embodiments, when the communication link connection between each plasma control unit is normal, the arc striking control communication interface located at the head end of the arc striking plate assembly line is used to generate a synchronous trigger signal, and send the synchronous trigger signal to the arc striking control communication interface located at the tail end of the arc striking plate assembly line via each plasma control unit, and the arc striking control communication interface at the tail end is used to return the synchronous response signal corresponding to the synchronous trigger signal to the arc striking control communication interface at the head end via each plasma control unit.

[0063] It should be noted that when the communication link between the plasma control units is connected normally, the arc control communication interface at the head and tail ends of the arc ignition plate assembly line plays a key role. The head end arc ignition control communication interface is responsible for generating a synchronous trigger signal, which is transmitted to the tail end arc ignition control communication interface through each plasma control unit. The tail end interface converts the received synchronous trigger signal into a synchronous response signal, and transmits it back to the head end interface through each control unit again. This process ensures the synchronous operation of each control unit on the arc ignition plate assembly line, thereby achieving efficient arc ignition control.

[0064] Specifically, the synchronization trigger signal can be an electrical signal or an optical signal, and its parameter settings include the frequency, phase and timing of the signal to ensure the synchronization of the signal during transmission. The arc ignition control communication interface at the head end and the tail end can be a specially designed hardware module, which has the functions of signal generation, reception and forwarding. These interfaces are connected to the second logic processing unit and the adjacent plasma control unit through a two-way digital communication interface unit to achieve accurate signal transmission.

[0065] Preferably, in order to improve the stability and anti-interference ability of the system, the generation and processing of the synchronous trigger signal can adopt a redundant design. For example, multiple sources of synchronous trigger signals can be set to ensure that the system can still work normally when a certain signal source fails. More specifically, self-diagnosis and error detection mechanisms can be integrated into the arc ignition control communication interface at the head end and the tail end to monitor the integrity and accuracy of the signal in real time during the signal transmission process. In addition, advanced signal encoding and decoding technology can be used to improve the transmission quality of the signal in a complex environment and reduce the loss and interference of the signal during the transmission process.

[0066] In some embodiments, each arc ignition control communication interface includes: a second logic processing unit and a bidirectional digital communication interface unit;

[0067] The bidirectional digital communication interface unit is respectively connected to the second logic processing unit and an adjacent plasma control unit;

[0068] The bidirectional digital communication interface unit of the arc ignition control communication interface at the head end is used to receive the synchronization trigger signal generated by the second logic processing unit of the arc ignition control communication interface, and send it to the bidirectional digital communication interface unit of the arc ignition control communication interface at the tail end via each plasma control unit;

[0069] The bidirectional digital communication interface of the arc ignition control communication interface at the tail end is used to send the synchronization trigger signal to the second logic processing unit of the arc ignition control communication interface, receive the synchronization response signal generated by the second logic processing unit, and return it to the second bidirectional digital communication interface unit of the arc ignition control communication interface at the head end via each plasma control unit. The second bidirectional digital communication interface unit sends the synchronization response signal to the second logic processing unit of the arc ignition control communication interface at the head end.

[0070] It should be noted that the design of each arc ignition control communication interface is intended to achieve efficient signal processing and transmission. These interfaces include a second logic processing unit and a bidirectional digital communication interface unit, which work together to ensure the synchronous transmission and response of signals on the arc ignition plate assembly line. The second logic processing unit is responsible for generating a synchronous trigger signal and sending it to the adjacent plasma control unit and the arc ignition control communication interface at the tail end through the bidirectional digital communication interface unit. After receiving the signal, the tail end interface generates a corresponding synchronous response signal and returns it to the head end interface through the same path to complete the closed-loop transmission of the signal.

[0071] Specifically, the second logic processing unit can be a microprocessor or FPGA integrated with a signal generation algorithm, which generates a synchronization trigger signal according to preset timing and logic conditions. The bidirectional digital communication interface unit is responsible for transmitting these signals to other units in digital form and receiving synchronization response signals from the tail end. The design of these interface units needs to consider the signal transmission rate, bandwidth and anti-interference ability to ensure the integrity and reliability of the signal during long-distance transmission.

[0072] Preferably, in order to improve the response speed of the system and reduce the delay of signal transmission, the bidirectional digital communication interface unit can be optimized. For example, high-speed serial communication technology, such as Gigabit Ethernet or high-speed serial bus, can be used to increase the transmission rate of the signal. More specifically, advanced signal modulation and demodulation technology can be integrated into the communication interface unit to improve the transmission efficiency and anti-interference ability of the signal. In addition, a signal buffering mechanism can be introduced into the system to cope with instantaneous signal transmission peaks and ensure the stable operation of the system under high load conditions. As an alternative, fiber optic communication technology can be considered to further improve the bandwidth and reliability of signal transmission.

[0073] like Figure 2As shown, a linear plasma arc ignition control method 200 of some embodiments includes:

[0074] Step 201, detecting the communication link status between plasma control units;

[0075] Step 202, when the communication link between the plasma control units is disconnected, the plasma control unit at the end of the arc ignition plate assembly line shields the start signal sent by the arc ignition control communication interface connected thereto;

[0076] Step 203, the disconnection includes one end of a plurality of plasma control units to form a dynamic network to control the linear plasma arcing on the arc-starting plate assembly line to perform group actions;

[0077] Step 204, the plasma control unit at the end generates a start signal and calculates the total time of the response signal, as shown in calculation formula (1);

[0078] Tresponse=Tsignal+Tprocess (1)

[0079] Where Tresponse is the total time of the response signal; Tsignal is the signal transmission time; and Tprocess is the processing time.

[0080] It is understood that the modules described in the linear plasma arc ignition control method 200 are similar to those described in the reference Figure 1 Therefore, the operations, features and beneficial effects described above for the linear plasma arc ignition control system are also applicable to the linear plasma arc ignition control method 200 and the modules contained therein, and will not be repeated here.

[0081] In some embodiments, the disconnection includes one end of a plurality of plasma control units to form a dynamic network to control the linear plasma arcing on the arc-starting plate assembly line to perform group actions, including:

[0082] The plasma control unit at the end generates a start signal and transmits the start signal to the plasma control unit at the end of the dynamic network;

[0083] The plasma control unit at the end of the dynamic network returns a response signal corresponding to the start signal to the plasma control unit at the corresponding end to form a dynamic network;

[0084] Calculate the total signal strength of all plasma control units in the dynamic network; as shown in calculation formula (2);

[0085]

[0086] In the formula, S net is the total signal strength of all plasma control units in the dynamic network; S unit,i is the signal strength of the i-th plasma control unit; S loss The signal is lost during the transmission process;

[0087] The linear plasma arc ignition on the arc ignition plate assembly line is controlled to perform group actions based on the total signal strength of all plasma control units in the dynamic network.

[0088] It should be noted that the control method of the linear plasma arc ignition control system pays special attention to the detection of the communication link status, and takes a series of measures to ensure the continuous operation of the system when the communication link is detected to be disconnected. Specifically, when the communication link between the plasma control units is disconnected, the system will shield the start signal through the plasma control unit at the end, and form a dynamic network at the disconnection point to control the linear plasma arc ignition on the arc ignition plate assembly line to perform group actions. The plasma control unit at the end generates a start signal and calculates the total time of the response signal to ensure the synchronization and consistency of the arc ignition process.

[0089] Specifically, the detection of the communication link status can be achieved by monitoring the transmission quality, delay or loss rate of the signal. If the link status does not meet the preset threshold, the system will automatically trigger the fault handling mechanism. After shielding the start signal, the plasma control unit at the end will use the built-in algorithm and communication protocol to work with other units to form a dynamic network. The total time for calculating the response signal involves the signal transmission time and processing time, which can be quantitatively calculated by formula (1), where the signal transmission time refers to the transmission delay of the signal on the communication link, and the processing time refers to the time required for the plasma control unit to process the signal.

[0090] Preferably, in order to improve the reliability and flexibility of the system, the formation process of the dynamic network can be further refined. For example, an adaptive algorithm can be designed to dynamically adjust the network structure and signal transmission path according to the number and characteristics of the plasma control units contained in the disconnection. More specifically, an intelligent diagnostic tool can be introduced to monitor the status of the communication link in real time, and automatically adjust the parameters or switch to a backup link when an abnormality is detected. In addition, wireless communication technology can also be considered as a supplement to wired communication to improve the fault tolerance and adaptability of the system. As an alternative, a distributed control strategy can be designed so that each plasma control unit can respond to link disconnection events independently in a local range, thereby reducing dependence on the central control unit.

[0091] In some embodiments, the disconnection includes one end of a plurality of plasma control units to form a dynamic network, including:

[0092] The central control switching device receives the dynamic network instruction sent by the host server, and sends the dynamic network instruction to the node switching device, and the node switching device sends the dynamic network instruction to one end of the disconnection point including multiple plasma control units, and the plasma control units at this end form a dynamic network according to the dynamic network instruction.

[0093] It should be noted that the control method of the linear plasma arc ignition control system further includes the coordinated work of the central control switching device and the node switching device to achieve precise control of the dynamic network. The central control switching device is responsible for receiving dynamic network instructions from the host computer server and sending them to the node switching device. These instructions instruct the node switching device on how to transmit signals to the plasma control unit at the disconnection point, thereby forming a dynamic network and ensuring that the linear plasma arc ignition on the arc ignition plate assembly line can perform group actions.

[0094] Specifically, the central control switching device can be a high-performance network switch or router with the ability to process large amounts of data and instructions. The node switching device can be a plurality of small switches or hubs distributed on the arc-starting plate assembly line, which are connected to the central control switching device and the plasma control unit. The dynamic network instructions are a series of control signals and parameters used to instruct the plasma control unit on how to respond to link disconnection events, including signal routing, synchronization and recovery strategies. These instructions can include parameters such as signal strength, transmission rate, priority, etc. to adapt to different working conditions and requirements.

[0095] Preferably, in order to improve the response speed and reliability of the system, the communication protocols of the central control switching device and the node switching device can be optimized. For example, priority queues and fast forwarding mechanisms can be used to ensure that key dynamic network instructions can be processed and transmitted quickly. More specifically, a dynamic network management protocol can be designed to allow the central control switching device to dynamically adjust the content of the issued instructions based on the real-time system status and performance indicators. In addition, redundancy mechanisms can be introduced, such as setting up multiple backup node switching devices to prevent the failure of a single device from causing the interruption of the entire network. As an alternative, wireless communication technology can be considered to assist the wired network, provide additional communication paths, and enhance the fault tolerance of the system.

[0096] In some embodiments, the disconnection includes one end of a plurality of plasma control units to form a dynamic network to control the linear plasma arcing on the arc-starting plate assembly line to perform group actions, including:

[0097] The bidirectional digital communication interface unit of the plasma control unit at the end receives the start signal generated by the first logic processing unit of the plasma control unit, and sends the start signal to the bidirectional digital communication interface unit of the plasma control unit at the end of the dynamic network;

[0098] The bidirectional digital communication interface unit of the plasma control unit at the end of the dynamic network sends the start signal to the first logic processing unit of the plasma control unit, receives a response signal corresponding to the start signal generated by the first logic processing unit, and returns the response signal to the bidirectional digital communication interface unit of the plasma control unit at the corresponding end, and the bidirectional digital communication interface unit sends the response signal to the first logic processing unit of the plasma control unit at the end, so as to form a dynamic network to control the linear plasma arc ignition on the arc ignition plate assembly line to perform group actions.

[0099] It should be noted that the linear plasma arc ignition control method describes in detail that when the communication link is disconnected, the group action of plasma arc ignition on the arc ignition plate assembly line can be realized through a dynamic network. Specifically, the plasma control unit at the end receives the start signal through its bidirectional digital communication interface unit and transmits these signals to the plasma control unit at the end of the dynamic network. After the end unit receives the start signal, it generates a corresponding response signal and returns it to the end unit through the same communication path to form a dynamic network to ensure the synchronous execution of the arc ignition action.

[0100] Specifically, the bidirectional digital communication interface unit of the end plasma control unit is composed of a signal driving module and a high-speed comparison module, which work together to achieve rapid transmission and processing of signals. The signal driving module is responsible for generating a start signal according to the instructions of the first logic processing unit, while the high-speed comparison module is responsible for receiving and comparing these signals to ensure the accuracy of the signal. At the end of the dynamic network, the corresponding module of the plasma control unit receives the start signal and triggers the first logic processing unit to generate a response signal, which is then returned to the end unit through the communication interface unit to complete the closed-loop transmission of the signal.

[0101] Preferably, in order to improve the stability and response speed of the system, the operating parameters of the two-way digital communication interface unit can be optimized. For example, the output strength and rate of the signal driving module can be adjusted to adapt to different communication environments and link qualities. More specifically, a signal quality feedback mechanism can be introduced to enable the system to dynamically adjust the operating parameters of the signal driving module and the high-speed comparison module according to the signal quality monitored in real time. In addition, advanced signal coding techniques, such as error control coding, can also be used to improve the transmission reliability of signals in complex environments. As an alternative, a multi-path routing algorithm can be considered so that when a communication link fails, the system can automatically select the best signal transmission path to ensure the continuity and consistency of arc control.

[0102] In some embodiments, a high-speed comparison module of a bidirectional digital communication interface unit on one side of a plasma control unit at the end of the dynamic network receives a start signal sent by a signal driving module of an adjacent plasma control unit, and sends the start signal to a first logic processing unit of the plasma control unit;

[0103] The signal driving module of the bidirectional digital communication interface unit on the other side of the plasma control unit at the end of the dynamic network receives the start signal sent by the first logic processing unit, and sends the start signal to the high-speed comparison module of the bidirectional digital communication interface unit, and the high-speed comparison module returns the start signal to the first logic processing unit of the plasma control unit.

[0104] It should be noted that when the high-speed comparison module of the bidirectional digital communication interface unit on one side of the plasma control unit at the end of the dynamic network receives the start signal sent by the signal driving module of the adjacent unit, the module transmits the signal to the first logic processing unit of the plasma control unit. Subsequently, the signal driving module of the bidirectional digital communication interface unit on the other side of the unit receives the start signal of the first logic processing unit and sends it to the high-speed comparison module, which then returns the start signal to the first logic processing unit to complete the closed-loop processing of the signal.

[0105] Specifically, the bidirectional digital communication interface unit of the plasma control unit at the end of the dynamic network is composed of a signal driving module and a high-speed comparison module. The signal driving module generates a start signal according to a preset logic and sends it to an adjacent plasma control unit through a communication link. The high-speed comparison module is responsible for receiving these signals and comparing them with preset thresholds or conditions to ensure the accuracy and timeliness of the signals. The first logic processing unit generates a response signal according to the comparison result and returns it to the adjacent unit through the same communication interface unit, forming a signal closed loop in the dynamic network.

[0106] Preferably, in order to improve the response speed and accuracy of the system, the operating parameters of the communication interface unit of the dynamic network terminal plasma control unit can be optimized. For example, the signal generation frequency and amplitude of the signal driving module can be adjusted to adapt to different working environments and requirements. More specifically, an adaptive algorithm can be introduced to enable the signal driving module and the high-speed comparison module to dynamically adjust their operating parameters according to the real-time signal quality and system status. In addition, a redundant design can be adopted to set a backup unit for the signal driving module and the high-speed comparison module to improve the fault tolerance of the system. As an alternative, it is possible to consider using different communication protocols or encoding methods to improve the transmission efficiency and reliability of signals in complex environments.

[0107] In some embodiments, it also includes:

[0108] When the communication links between the plasma control units are connected normally, the arc striking control communication interface at the head end of the arc striking plate assembly line generates a synchronous trigger signal, and sends the synchronous trigger signal to the arc striking control communication interface at the tail end of the arc striking plate assembly line via the plasma control units, and the communication interface returns the synchronous response signal corresponding to the synchronous trigger signal to the arc striking control communication interface at the head end via the plasma control units;

[0109] The arc striking control communication interface at the head end of the arc striking plate assembly line generates a synchronous trigger signal, and sends the synchronous trigger signal to the arc striking control communication interface at the tail end of the arc striking plate assembly line via each plasma control unit, and the communication interface returns the synchronous response signal corresponding to the synchronous trigger signal to the arc striking control communication interface at the head end via each plasma control unit, including:

[0110] The bidirectional digital communication interface unit of the arc ignition control communication interface at the head end receives the synchronization trigger signal generated by the second logic processing unit of the arc ignition control communication interface, and sends it to the bidirectional digital communication interface unit of the arc ignition control communication interface at the tail end via each plasma control unit;

[0111] The bidirectional digital communication interface of the arc ignition control communication interface at the tail end sends the synchronization trigger signal to the second logic processing unit of the arc ignition control communication interface, receives the synchronization response signal generated by the second logic processing unit, and returns it to the second bidirectional digital communication interface unit of the arc ignition control communication interface at the head end via each plasma control unit, and the second bidirectional digital communication interface unit sends the synchronization response signal to the second logic processing unit of the arc ignition control communication interface at the head end.

[0112] It should be noted that the arc ignition control communication interface at the head end is responsible for generating a synchronous trigger signal when the communication link is normal, and transmitting it to the arc ignition control communication interface at the tail end through each plasma control unit. After receiving the synchronous trigger signal, the tail end interface generates a corresponding synchronous response signal, which is then returned to the head end interface through each plasma control unit to complete the closed-loop transmission of the signal. This mechanism ensures the synchronization and consistency of the plasma arc ignition action on the arc ignition plate assembly line.

[0113] Specifically, the synchronization trigger signal is a control signal used to ensure synchronous operation between plasma control units. The arc ignition control communication interface at the head end can be an electronic module that integrates signal generation logic, which generates a synchronization trigger signal according to a preset time interval or condition. The arc ignition control communication interface at the tail end is responsible for receiving these signals and generating a synchronization response signal after processing. The transmission and return of these signals are realized through the communication link between the plasma control units, and the communication link can be an electrical connection, a wireless connection or other forms of signal transmission.

[0114] Preferably, in order to improve the transmission efficiency and accuracy of the synchronous trigger signal, the arc ignition control communication interface at the head end and the tail end can be optimized. For example, a high-precision clock synchronization technology can be used to ensure the precise alignment of the generation and reception of the signal in time. More specifically, a real-time clock and synchronization mechanism can be integrated in the communication interface unit to achieve precise time control of the signal. In addition, advanced signal modulation and demodulation technology can be used to improve the transmission quality of the signal in a complex environment and reduce the loss and interference of the signal during the transmission process. As an alternative, the use of optical fiber communication technology can be considered to further improve the bandwidth and reliability of signal transmission. At the same time, an error detection and correction mechanism can be introduced to ensure the integrity and accuracy of the synchronous trigger signal and the synchronous response signal.
