The terminal node may also be other devices with terminal functions, for example, the terminal node may also be a device functioning as a terminal in D2D communication. The embodiment of the application does not limit the equipment form of the terminal node, and the device for realizing the function of the terminal can be the terminal node or can be a device capable of supporting the terminal to realize the function, such as a chip system. The device may be installed in or used in cooperation with a terminal. In the embodiment of the application, the chip system can be composed of chips, and can also comprise chips and other discrete devices.

In the embodiment of the application, the equipment in the equipment cluster comprises a lithium ion battery pole piece coating and recycling integrated machine which is advanced battery manufacturing equipment and plays a key role in the battery production process. The equipment is mainly used for coating the pole pieces, namely, the positive pole piece and the negative pole piece of the lithium ion battery are respectively coated with corresponding electrolyte materials. The coating process is an important element in the battery manufacturing process and directly affects the quality and performance of the battery. Conventional coating apparatuses have problems such as slow coating speed, low coating accuracy, poor stability, etc., which limit the efficiency and quality of battery production. In order to solve the problems, a lithium ion battery pole piece coating and recycling integrated machine is generated. The device adopts advanced coating technology and an automatic control system, and can realize a rapid, accurate and stable coating process. Meanwhile, the coating agent also has a recycling function, and can treat waste materials and pollutants generated in the coating process, so that the influence of battery production on the environment is reduced.

The terminal is provided with a plurality of antenna panels (pannel), such as M antenna panels. Each of the M antenna panels may transmit or receive a plurality of beams in a different direction, referred to as the plurality of beams of that antenna panel.

A beam refers to a special transmitting or receiving effect with directivity formed by a transmitter or receiver of a network device or terminal through an antenna array, similar to a beam formed by a flashlight converging light into one direction. The signal is sent and received in a beam mode, so that the transmission data distance of the signal can be effectively improved. The beams used for communication between terminals may also be referred to as sidelobes.

The beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, or a hybrid digital/analog beamforming technique, etc.

The beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, the terminal feeds back the measured resource quality, and 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 (state) through a transmission configuration number (transmission configuration index, TCI) field in downlink control information (downlink control information, DCI), and the terminal determines a beam corresponding to the reference resource according to the reference resource included in the TCI-state.

The beam used to transmit the signal may be referred to as a transmit beam (transmission beam, or Tx beam), spatial transmit filter (spatial domain transmission filter), spatial transmit filter (spatial transmission filter), spatial transmit parameters (spatial domain transmission parameter), spatial transmit parameters (spatial transmission parameter), and the like. The beams used to receive the signals may be referred to as receive beams (or Rx beams), spatial receive filters (spatial domain reception filter), spatial receive filters (spatial reception filter), spatial receive parameters (spatial domain reception parameter), spatial receive parameters (spatial reception parameter), and the like.

It will be appreciated that embodiments of the application are described in terms of beams in general, but that beams may alternatively be understood as other equivalent concepts and are not limited to the concepts mentioned above.

In the control system, the monitoring terminal can monitor the working state of the whole equipment cluster under the condition that a small amount of equipment, such as M machine equipment, has working state asynchronism so as to observe whether the working state asynchronism of the small amount of equipment can influence the whole cluster. Therefore, under the condition that N pieces of machine equipment are affected and the working states are asynchronous, the monitoring terminal can at least resynchronize clocks among the N pieces of machine equipment in the equipment cluster, so that the working states of the N pieces of machine equipment are kept synchronous continuously through clock resynchronization, the stability and the reliability of networking control can be improved, and the production efficiency is guaranteed.

It is convenient to understand that a state monitoring method of the lithium ion battery pole piece coating and recycling integrated machine provided by the embodiment of the application in connection with fig. 2 is specifically described below.

Exemplary, fig. 2 is a schematic flow chart of a state monitoring method of a lithium ion battery pole piece coating and recycling integrated machine according to an embodiment of the present application. The method can be applied to the application function entity and the geographic position information system in the control system.

As shown in fig. 2, the flow of the state monitoring method of the lithium ion battery pole piece coating and recycling integrated machine is as follows:

S201, under the condition that the working states of M machine devices are reported to a monitoring terminal asynchronously, M is an integer larger than 1, and the monitoring terminal monitors the working states of the device clusters where the M machine devices are located.

The equipment in the equipment cluster comprises lithium ion battery pole piece coating and recycling integrated machines, and the working state asynchronism refers to the condition that synchronous coordination among different lithium ion battery pole piece coating and recycling integrated machines is asynchronous. For example, the lithium ion battery pole piece coating and recycling integrated machine 1 performs the procedure a, the lithium ion battery pole piece coating and recycling integrated machine 2 needs to be matched with the lithium ion battery pole piece coating and recycling integrated machine 1 to perform the procedure B later, so that 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 can establish a coupling relationship, namely side communication connection, namely communication can be performed through beams on antenna panels respectively arranged on 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, for example, 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 can determine beam pairs through beam measurement, for example, a receiving beam and a transmitting beam with the best signal quality are used by a transmitting end, and the receiving end correspondingly uses the receiving beam to perform corresponding receiving behavior by the transmitting end. Thus, when the lithium ion battery pole piece coating and recovering integrated machine 1 completes the process a at the time t1, the lithium ion battery pole piece coating and recovering integrated machine 1 can inform the lithium ion battery pole piece coating and recovering integrated machine 2 of itself that the process a is completed at the time t1 through side communication, so that the lithium ion battery pole piece coating and recovering integrated machine 2 is ready to cooperate with the execution process B at the later time t 2. However, since the time of the two is not asynchronous due to the error, the lithium ion battery pole piece coating and recovering integrated machine 1 may not actually perform the process a at the time t1, which leads to the misoperation of the lithium ion battery pole piece coating and recovering integrated machine 2 at the time t2, which is called synchronous coordination and asynchronous. If the lithium ion battery pole piece coating and recycling integrated machine 2 is in misoperation at the time t2, the lithium ion battery pole piece coating and recycling integrated machine 1 is informed, and meanwhile, the working state can be determined to be asynchronous, so that the working state is reported 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 state is asynchronous according to the feedback of the lithium ion battery pole piece coating and recycling integrated machine 2, so that the working state is reported to the monitoring terminal, and therefore, M machine devices report the working state asynchronously to the monitoring terminal.

Under the condition that the working states of the M machine devices are reported to the monitoring terminal asynchronously, the M machine devices can determine that the M machine devices belong to the device cluster, for example, the identifiers are determined to be identical with the identifiers of the devices in the device cluster according to the respective identifiers of the M machine devices. The M machine devices may obtain the topological relationship between the devices contained in the device cluster locally. The topological relation is used for indicating the communication coupling relation between the devices contained in the device cluster. The topological relation between devices contained in the device cluster refers to a beam coupling relation between every two devices with a direct coupling relation in the device cluster, the beam coupling relation between every two devices refers to one or two beam pairs used by the two devices for communication, if one beam pair is a transmitting beam and a receiving beam, the beam pair is used for indicating that the two devices are in a unidirectional coupling relation, and if the two beam pairs are two beam pairs, the two beam pairs are respectively a transmitting beam and a receiving beam, and the two devices are used for indicating that the two devices are in a bidirectional coupling relation. In other words, since devices in the device cluster can perform networking by side-by-side communication, the topological relationship can be represented by beam pairs. For example, in the device 1, the device 2, and the device 3, there are two beam pairs of the device 1 and the device 2, which are the best transmission beam of the device 1 and the best reception beam of the device 2, respectively, and the best reception beam of the device 1 and the best transmission beam of the device 2. One beam pair of device 2 and device 3 is the best transmit beam for device 3 and the best receive beam for device 2. Thus, the topological relation among the device 1, the device 2 and the device 3 is that the device 1 ↔ and the device 2 are the devices 3.

In this way, the M machine devices may determine that the M machine devices have a coupling relationship according to a topological relationship between devices included in the device cluster. Correspondingly, the monitoring terminal monitors the working states of the equipment clusters where the M machine equipment are located, and the monitoring terminal monitors the working states of the equipment clusters if the monitoring terminal has a coupling relation according to the M machine equipment, otherwise, the monitoring terminal does not monitor the working states of the equipment clusters. In other words, if the monitoring terminal does not have a coupling relationship according to the M machine devices, the working state asynchronization may not be diffused along with the coupling relationship, so that it is not necessary to monitor the working state of the device cluster, so as to save the overhead.

S202, if the monitoring terminal monitors the working state of the equipment cluster, and determines that the working state of N pieces of equipment including M pieces of equipment is asynchronous, and N is an integer greater than M, the monitoring terminal at least resynchronizes clocks among the N pieces of equipment in the equipment cluster.

The method 1 comprises the steps that a monitoring terminal can determine K1 machine equipment with coupling relation with M machine equipment according to topological relation among equipment contained in an equipment cluster, wherein the K1 machine equipment is a subset of the equipment cluster, K1 is an integer larger than N, and the monitoring terminal monitors working states of the K1 machine equipment to determine that the K1 machine equipment has working states asynchronism including the M machine equipment and the N machine equipment.

The monitoring terminal can determine P coupling levels of the devices with coupling relation with M machine devices according to the topological relation among the devices contained in the device cluster and the number of the devices in the device cluster, wherein P is an integer greater than 1, and the value of P is positively related to the number of the devices in the device cluster. In the P coupling levels, the equipment of the 1 st coupling level is directly coupled with M machine equipment, the equipment of the 2 nd coupling level is indirectly coupled with the M machine equipment through at least two coupling levels, the equipment of the 3 rd coupling level is indirectly coupled with the M machine equipment through at least four coupling levels, and the like until the equipment of the P coupling level, and the monitoring terminal can determine the equipment contained in the P coupling levels as K1 machine equipment with coupling relation of the M machine equipment. For example, the topological relation is that the equipment 1- & gt equipment 2- & gt equipment 3- & gt equipment 4- & gt equipment 5, wherein the equipment 1 is equipment in M pieces of equipment, the rest equipment 2-equipment 5 does not belong to equipment in M pieces of equipment. If p=2, then the device of the 1 st coupling level is device 2 and the device of the 2 nd coupling level is device 4 or device 5. That is, by defining different coupling levels, indirect coupling is required, so that the range of the monitored K1 machine devices can be larger, so as to realize overall evaluation of the working states of the device clusters.

And 2, the monitoring terminal inputs the topological relation among the devices contained in the device cluster and the topological positions of the M machine devices in the topological relation into the deep neural network model for analysis, and K2 machine devices output by the deep neural network model are obtained. The monitoring terminal can determine that the working states of the K2 machine devices are asynchronous when the working states of N machine devices including M machine devices are included by monitoring the working states of the K2 machine devices.

The monitoring terminal monitors the working state of the equipment cluster, namely the monitoring terminal indicates equipment in the equipment cluster to report own clocks, and if the clock deviation of two machine equipment with coupling relation in the equipment cluster exceeds a threshold value, the condition that the two machine equipment with coupling relation are asynchronous is indicated. For example, the monitoring terminal may instruct each of the K1 machine devices or the K2 machine devices that have a coupling relationship to periodically report its own clock in the monitoring period, where in this case, if the clock deviation reported by the two machine devices that have a coupling relationship exceeds a threshold, it indicates that the two machine devices that have a coupling relationship are about to have an asynchronous working state. In other words, the N machine devices include devices for which the working state asynchronization has occurred, and devices for which the working state asynchronization is to occur.

On the basis, the monitoring terminal determines whether at least one master clock device exists in N machine devices, wherein the master clock device can synchronize clocks of the N machine devices to non-clock devices managed by the master clock device, if at least one master clock device exists in the N machine devices, the monitoring terminal enables the clocks of the N machine devices to be connected with the at least one master clock device, otherwise, if at least one master clock device does not exist in the N machine devices, the monitoring terminal enables the clocks of the N machine devices to be connected with the N machine devices. For example, N machine devices 1 are used as master clock devices, and devices 2-5 managed by the device 1 are also used as non-master clock devices, the monitoring terminal can synchronize its own clock with the device 1, for example, by adopting a gPTP mode, and then the device 1 can actively synchronize the clock with the devices 2-5 according to its own clock update, for example, by adopting a gPTP mode. Or the monitoring terminal at least resynchronizes clocks among N machine devices in the device cluster, including synchronizing own clocks with source end devices in N machine devices indicated by the topological relation among the N machine devices according to the topological relation among the N machine devices and indicating the source end devices to synchronize own clocks with devices with coupling relation. The source device may be M machine devices, so that the M machine devices may synchronize their clocks with devices directly coupled to themselves, and these devices may synchronize their clocks with devices directly coupled to themselves in the next hierarchy, so that synchronization is diffused until at least M machine devices are synchronized.

Optionally, the method further comprises the monitoring terminal synchronizing its own clock with the clock of the radio access network device (base station) to which the monitoring terminal is accessing, e.g. by means of gPTP, before synchronizing its own clock with the at least M machine devices.

In summary, when a small amount of equipment, such as M machine equipment, has an asynchronous working state, the monitoring terminal can monitor the working state of the whole equipment cluster to see whether the working state of the small amount of equipment is asynchronous or not. Therefore, under the condition that N pieces of machine equipment are affected and the working states are asynchronous, the monitoring terminal can at least resynchronize clocks among the N pieces of machine equipment in the equipment cluster, so that the working states of the N pieces of machine equipment are kept synchronous continuously through clock resynchronization, the stability and the reliability of networking control can be improved, and the production efficiency is guaranteed.

The state monitoring method of the lithium ion battery pole piece coating and recycling integrated machine provided by the embodiment of the application is described in detail with reference to fig. 2.
