This equipment is mainly used for coating pole pieces, that is, coating the positive and negative pole pieces of lithium-ion batteries with corresponding electrolyte materials respectively. The coating process is an important link in the battery manufacturing process, which directly affects the quality and performance of the battery. There are some problems with traditional coating equipment, such as slow coating speed, low coating accuracy, poor stability, etc. These problems limit the efficiency and quality of battery production. In order to solve these problems, the lithium-ion battery pole piece coating and recycling machine came into being. This equipment adopts advanced coating technology and automatic control system, which can realize a fast, accurate and stable coating process. At the same time, it also has a recycling function, which can process the waste and pollutants generated in the coating process and reduce the impact of battery production on the environment.

[0003] At present, with the maturity of intelligent control and Internet of Things technology, the lithium-ion battery pole piece coating and recycling machine can also be networked. This means that multiple devices can be connected together to form a device cluster. In this way, efficient control and management of the entire battery production line can be achieved. The networked device cluster can realize data sharing and communication, and improve the intelligence level of the production line. At the same time, the collaborative work between devices can also improve production efficiency and reduce production costs. Therefore, the networking technology of the lithium-ion battery pole piece coating and recycling machine is of great significance to the battery production industry.

[0004] However, in the case of networking, the device cluster may operate asynchronously, which may affect the stability and reliability of its control, thereby affecting production efficiency. Summary of the invention

[0005] The embodiment of the present application provides a state monitoring method for a lithium-ion battery pole piece coating and recycling integrated machine, which is used to improve the stability and reliability of network control, thereby ensuring production efficiency.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

In this way, when N machines are affected and are about to have asynchronous working states, the monitoring terminal can at least resynchronize the clocks between the N machines in the device cluster, so that the working states of the N machines can continue to be synchronized through clock resynchronization, which can improve the stability and reliability of network control and thus ensure production efficiency.

Figure 1 As shown, the control system includes: a monitoring terminal, and a device cluster connected to the monitoring terminal for communication.

[0033] Both the monitoring terminal and the device cluster can be terminals with transceiver functions, or can be chips or chip systems set in the terminal.

The device may be installed in the terminal or used in combination with the terminal. In the embodiments of the present application, the chip system may be composed of chips, or may include chips and other discrete devices.

[0034] In the embodiment of the present application, taking the equipment in the equipment cluster including the lithium-ion battery pole piece coating and recycling integrated machine as an example, the lithium-ion battery pole piece coating and recycling integrated machine is an advanced battery manufacturing equipment, which plays a key role in the battery production process. This equipment is mainly used for coating pole pieces, that is, coating the positive and negative pole pieces of the lithium-ion battery with corresponding electrolyte materials respectively. The coating process is an important link in the battery manufacturing process, which directly affects the quality and performance of the battery. There are some problems with traditional coating equipment, such as slow coating speed, low coating accuracy, poor stability, etc., which limit the efficiency and quality of battery production. In order to solve these problems, the lithium-ion battery pole piece coating and recycling integrated machine came into being. This equipment adopts advanced coating technology and automated control system, which can realize a fast, accurate and stable coating process. At the same time, it also has a recycling function, which can process the waste and pollutants generated in the coating process and reduce the impact of battery production on the environment.

[0035] The terminal is provided with multiple antenna panels (pannels), such as M antenna panels. Each of the M antenna panels can transmit or receive multiple beams in different directions, which are called multiple beams of the antenna panel.

[0036] A beam is a special directional transmission or reception effect formed by the transmitter or receiver of a network device or terminal through an antenna array, similar to the beam formed by a flashlight converging light in one direction. Sending and receiving signals in the form of a beam can effectively increase the transmission distance of the signal. The beam used for communication between terminals can also be called a side beam.

[0037] The beam may be a wide beam, a narrow beam, or other types of beams. The beam forming technology may be a beam forming technology or other technologies. The beam forming technology may specifically be a digital beam forming technology, an analog beam forming technology, or a hybrid digital / analog beam forming technology.

[0038] Beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, and the terminal feeds back the measured resource quality, so that the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication-state through the transmission configuration index (TCI) field in the downlink control information (DCI), and the terminal determines the beam corresponding to the reference resource based on the reference resource contained in the TCI-state.

[0039] The beam can be specifically characterized as a digital beam, an analog beam, a spatial domain filter, a spatial filter, a spatial parameter, TCI, a TCI-state, etc. A beam used to send a signal can be called a transmission beam (or Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, etc. A beam used to receive a signal can be called a reception beam (or Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, etc.

[0040] It can be understood that the embodiments of the present application are uniformly described using beams, but beams can be replaced by other equivalent concepts and are not limited to the concepts mentioned above.

[0041] In this control system, when a small number of devices, such as M machines, have asynchronous working states, the monitoring terminal can monitor the working state of the entire device cluster to observe whether the asynchronous working state of a small number of devices will affect the entire cluster. In this way, when N machines are affected and are about to have asynchronous working states, the monitoring terminal can at least resynchronize the clocks between the N machines in the device cluster, so that the working states of the N machines can continue to be synchronized through clock resynchronization, which can improve the stability and reliability of the network control, thereby ensuring production efficiency.

[0042] For ease of understanding, the following will combine Figure 2 The state monitoring method of the lithium-ion battery pole piece coating and recycling integrated machine provided in the embodiment of the present application is specifically described.

[0043] For example, Figure 2The present invention provides a flow chart of a method for monitoring the state of a lithium-ion battery pole piece coating and recycling machine. The method can be applied to the application function entity and geographic location information system in the above control system.

[0044] like Figure 2 As shown, the process of the state monitoring method of the lithium-ion battery pole piece coating and recycling integrated machine is as follows:

[0045] S201, when M machine devices report their working status asynchronously to the monitoring terminal, where M is an integer greater than 1, the monitoring terminal monitors the working status of the device cluster where the M machine devices are located.

[0046] The equipment in the equipment cluster includes a lithium-ion battery pole piece coating and recycling integrated machine, and asynchronous working status refers to the situation where the synchronization between different lithium-ion battery pole piece coating and recycling integrated machines is asynchronous. For example, lithium-ion battery pole piece coating and recycling integrated machine 1 performs process A, and lithium-ion battery pole piece coating and recycling integrated machine 2 needs to cooperate with it to perform process B afterwards, then lithium-ion battery pole piece coating and recycling integrated machine 1 and lithium-ion battery pole piece coating and recycling integrated machine 2 can establish a coupling relationship, that is, a side communication connection, which can be through the beams on the antenna panels of the lithium-ion battery pole piece coating and recycling integrated machine 1 and the lithium-ion battery pole piece coating and recycling integrated machine 2 respectively set to communicate, such as lithium-ion battery pole piece coating and recycling integrated machine 1 and lithium-ion battery pole piece coating and recycling integrated machine 2 will determine the beam pair through beam measurement, such as the receiving beam and the transmitting beam with the best signal quality, the transmitting end uses the transmitting beam to perform the transmitting behavior, and the receiving end uses the receiving beam to perform the corresponding receiving behavior accordingly. In this way, when the lithium-ion battery pole piece coating and recycling integrated machine 1 completes process A at time t1, the lithium-ion battery pole piece coating and recycling integrated machine 1 can inform the lithium-ion battery pole piece coating and recycling integrated machine 2 through side communication that it has completed process A at time t1, so that the lithium-ion battery pole piece coating and recycling integrated machine 2 is ready to cooperate in executing process B at the subsequent time t2. However, since the time of the two is not synchronized due to errors, the lithium-ion battery pole piece coating and recycling integrated machine 1 may not actually complete process A at time t1, which will cause the lithium-ion battery pole piece coating and recycling integrated machine 2 to misoperate at time t2. This situation is the so-called synchronous cooperation becoming asynchronous. If the lithium-ion battery pole piece coating and recycling integrated machine 2 misoperates at time t2 and informs the lithium-ion battery pole piece coating and recycling integrated machine 1, it can also determine that the working status is asynchronous, and report it to the monitoring terminal. At this time, the lithium-ion battery pole piece coating and recycling integrated machine 1 can also determine that the working status is asynchronous based on the feedback of the lithium-ion battery pole piece coating and recycling integrated machine 2, and then report it to the monitoring terminal. In this way, M machines and equipment report the working status asynchronously to the monitoring terminal.

[0047] In the case where M machine devices report their working status asynchronously to the monitoring terminal, the M machine devices can determine that the M machine devices belong to a device cluster, such as determining that these identifiers are the same as the identifiers of the devices in the device cluster based on the respective identifiers of the M machine devices. The M machine devices can obtain the topological relationship between the devices contained in the device cluster locally. Among them, the topological relationship is used to indicate the communication coupling relationship between the devices contained in the device cluster. The topological relationship between the devices contained in the device cluster refers to the beam coupling relationship between every two devices with a direct coupling relationship in the device cluster. The beam coupling relationship between every two devices refers to one or two beam pairs used for communication between the two devices. If it is a beam pair, the beam pair is a transmitting beam and a receiving beam, which is used to indicate that the two devices are in a unidirectional coupling relationship. If it is two beam pairs, the two beam pairs are respectively a transmitting beam and a receiving beam, which are used to indicate that the two devices are in a bidirectional coupling relationship. In other words, since the devices in the device cluster can communicate sideways for networking, the topological relationship can also be represented by beam pairs. For example, among device 1, device 2, and device 3, device 1 and device 2 have two beam pairs, namely, the best transmit beam of device 1 and the best receive beam of device 2, and the best receive beam of device 1 and the best transmit beam of device 2. Device 2 and device 3 have one beam pair, namely, the best transmit beam of device 3 and the best receive beam of device 2. In this way, the topological relationship among device 1, device 2, and device 3 is: device 1↔device 2←device 3.

[0048] In this way, the M machine devices can determine that there is a coupling relationship between the M machine devices according to the topological relationship between the devices included in the device cluster. Accordingly, the monitoring terminal monitors the working status of the device cluster where the M machine devices are located, including: if the monitoring terminal determines that there is a coupling relationship between the M machine devices, the monitoring terminal monitors the working status of the device cluster, otherwise, the monitoring terminal does not monitor the working status of the device cluster. In other words, if the monitoring terminal determines that there is no coupling relationship between the M machine devices, the working status asynchrony may not spread with the coupling relationship, so there is no need to monitor the working status of the device cluster to save overhead.

[0049] S202, if the monitoring terminal determines that N machine devices including M machine devices have asynchronous working status by monitoring the working status of the device cluster, where N is an integer greater than M, the monitoring terminal resynchronizes the clocks of at least the N machine devices in the device cluster.

[0050] Method 1: The monitoring terminal can determine K1 machine devices that have a coupling relationship with M machine devices based on the topological relationship between the devices included in the device cluster, where the K1 machine devices are a subset of the device cluster, and K1 is an integer greater than N; the monitoring terminal determines that the K1 machine devices have N machine devices including the M machine devices with asynchronous working status by monitoring the working status of the K1 machine devices.

[0051] The monitoring terminal can determine the P coupling levels of devices that have a coupling relationship with the M machine devices according to the topological relationship between the devices included in the device cluster and the number of devices in the device cluster, where P is an integer greater than 1, and the value of P is positively correlated with the number of devices in the device cluster. In the P coupling levels, the devices in the first coupling level are directly coupled with the M machine devices, the devices in the second coupling level are indirectly coupled with the M machine devices through at least two coupling level devices, the devices in the third coupling level are indirectly coupled with the M machine devices through at least four coupling level devices, and so on, until the devices in the Pth coupling level; the monitoring terminal can determine the devices included in the P coupling levels as K1 machine devices that have a coupling relationship with the M machine devices. For example, the topological relationship is: device 1→device 2→device 3→device 4→device 5, device 1 is a device among the M machine devices that belong to the M machine devices, and the remaining devices 2-device 5 do not belong to the M machine devices. If P = 2, the device at the first coupling level is device 2, and the device at the second coupling level is device 4 or device 5. In other words, by defining different coupling levels as requiring indirect coupling, the range of K1 monitored machine devices can be larger, so as to achieve an overall evaluation of the working status of the device cluster.

[0052] Method 2: The monitoring terminal inputs the topological relationship between the devices included in the device cluster and the topological positions of the M machine devices in the topological relationship into the deep neural network model for analysis, and obtains K2 machine devices output by the deep neural network model. Among them, the K2 machine devices are a subset of the device cluster, and K2 is an integer greater than N; the monitoring terminal can monitor the working status of the K2 machine devices and determine that the working status of N machine devices including the M machine devices among the K2 machine devices is asynchronous.

[0053] Among them, the monitoring of the working status of the device cluster by the monitoring terminal means that the monitoring terminal instructs the devices in the device cluster to report their own clocks. If the clock deviation of two coupled machine devices in the device cluster exceeds the threshold, it means that the two coupled machine devices will have asynchronous working status. For example, the monitoring terminal can instruct every two coupled devices in K1 machine devices or K2 machine devices to periodically report their own clocks during the monitoring time period. In this case, if the clock deviation reported by the two coupled machine devices exceeds the threshold, it means that the two coupled machine devices will have asynchronous working status. In other words, the N machine devices include devices that have already had asynchronous working status and devices that will have asynchronous working status.

[0054] On this basis, the monitoring terminal determines whether there is at least one master clock device among the N machine devices, wherein the master clock device can synchronize its own clock to the non-clock devices managed by the master clock device; if there is at least one master clock device among the N machine devices, the monitoring terminal synchronizes its own clock with the at least one master clock device, otherwise, if there is no at least one master clock device among the N machine devices, the monitoring terminal synchronizes its own clock with the N machine devices. For example, among the N machine devices, device 1 is the master clock device, and devices 2-5 managed by device 1 are non-master clock devices. The monitoring terminal can synchronize its own clock with device 1, such as by using gPTP. After that, device 1 can actively complete clock synchronization with devices 2-5 according to its own clock update, such as by using gPTP. Or; the monitoring terminal resynchronizes the clocks between at least the N machine devices in the device cluster, including: the monitoring terminal synchronizes its own clock with the source device among the N machine devices indicated by the topological relationship between the N machine devices according to the topological relationship between the N machine devices, and instructs the source device to synchronize its own clock to the device with which it has a coupling relationship. Among them, the source device can be M machine devices, so that the M machine devices can synchronize their own clocks to the devices directly coupled to themselves, and these devices can synchronize their own clocks to the devices at the next level and directly coupled to themselves, thus achieving the diffusion of synchronization until at least M machine devices are synchronized.

[0055] Optionally, the method also includes: before synchronizing its own clock with at least M machine devices, the monitoring terminal synchronizes its own clock with the clock of a wireless access network device (base station) to which the monitoring terminal is connected, such as synchronizing using gPTP.

[0056] In summary, when a small number of devices, such as M machines, have asynchronous working states, the monitoring terminal can monitor the working state of the entire device cluster to observe whether the asynchronous working state of a small number of devices will affect the entire cluster. In this way, when N machines are affected and are about to have asynchronous working states, the monitoring terminal can at least resynchronize the clocks between the N machines in the device cluster, so that the working states of the N machines can continue to be synchronized through clock resynchronization, which can improve the stability and reliability of network control, thereby ensuring production efficiency.
