Description

Multi-channel communication control method and system for vacuum coating machine

Technical Field

The invention relates to the field of communication, in particular to a multi-channel communication control method and system for a vacuum coating machine.

Background

In the production and processing process of the crystal, a vacuum coating machine is required to be used for coating the crystal, and the crystal is required to be subjected to light transmission coating in the field of solid state lasers, chips or missiles. Currently, with advances in automated control technology, vacuum coaters have enabled remote control via wireless communication, such as dispatch/Grant Free (GF) transmission as defined by the third generation partnership project (3rd generation partnership project,3GPP). GF transmission is characterized by a relatively small transmission delay. For example, before uplink transmission, the vacuum coating machine does not need to acquire time-frequency resources and transmission parameters used for transmitting data by monitoring a network side, such as dynamic authorization of a base station, but uses preconfigured GF resources, such as time-frequency resources and transmission parameters, to transmit data to the base station, where the GF resources are usually configured by the base station through higher layer signaling.

However, in future communication scenarios, the same GF resource may be multiplexed by multiple terminals at the same time, resulting in resource collision, and the transmission performance is affected, thereby affecting the stability of control of the vacuum coating machine.

Disclosure of Invention

The embodiment of the invention provides a multi-channel communication control method and a multi-channel communication control system for a vacuum coating machine, which are used for reducing the influence of GF (glass fiber) resource conflict on transmission performance so as to improve the control stability of the vacuum coating machine.

In order to achieve the above purpose, the invention adopts the following technical scheme:

in a first aspect, a method for controlling multiplex communication of a vacuum coating machine is provided, and the method is applied to the vacuum coating machine, and the vacuum coating machine is connected to access network equipment, and comprises the following steps: the working state of the vacuum coating machine is determined to be abnormal by monitoring the working state of the vacuum coating machine; responding to the abnormal working state of the vacuum coating machine, and sending working state warning information to access network equipment by the vacuum coating machine on each GF resource in N non-scheduling GF resources, wherein N is an integer greater than 1, and the working state warning information is used for indicating the abnormal working state of the vacuum coating machine.

In a possible design, when the vacuum coating machine is connected to the access network device, the vacuum coating machine is configured with M GF resources by the access network device, where M is an integer greater than or equal to N, and in response to an abnormal working state of the vacuum coating machine, the vacuum coating machine sends, on each GF resource of the N non-scheduled GF resources, working state alert information to the access network device, including: responding to the abnormal working state of the vacuum coating machine, and selecting N GF resources from M GF resources by the vacuum coating machine; the vacuum coating machine sends working state warning information to the access network equipment on each GF resource in the N GF resources.

That is, the vacuum coating machine may default to be configured with more GF resources, such as M transmission resources, so that N resources to be used subsequently may be selected, so as to reduce the possibility of GF resource collision and reduce the influence of GF resource collision on transmission performance.

Optionally, the N GF resources are different GF resources, and the vacuum plating machine selects the N GF resources from the M GF resources, including: generating a random number #1 by the vacuum coating machine, wherein the value x1 of the random number #1 is a positive integer; the vacuum coating machine determines the y1 GF resource in the M GF resources as the 1 st selected GF resource according to x1mod N=y1; generating a random number #2 by the vacuum coating machine, wherein the value x2 of the random number #2 is a positive integer; and determining that the y2 th GF resource in the M GF resources is the GF resource in the 2 nd selection according to x2mod N=y2 by the vacuum coating machine, and so on until the yn GF resource in the M GF resources is the GF resource in the N selection, wherein yn is an integer from 1 to N, and the yn GF resource is different from the N-1 GF resource selected before the N GF resource in the N selection.

It can be seen that the N GF resources may be randomly selected by generating different random numbers, which may be understood that GF resources of different terminals may be randomly selected, so as to further reduce the possibility of GF resource collision by random selection, thereby further reducing the influence of GF resource collision on transmission performance.

Further, each GF resource of the N GF resources includes a plurality of time-frequency resources distributed in a matrix, a first time-frequency resource of the plurality of time-frequency resources carrying a reference signal, the method further comprising: and the vacuum coating machine loads the working state warning information to a second time-frequency resource in the time-frequency resources according to the position of the first time-frequency resource in the time-frequency resources.

For example, the second time-frequency resource is a first number of a plurality of second time-frequency resources, and the vacuum coating machine carries the working state warning information to the second time-frequency resource in the plurality of time-frequency resources according to the time-frequency position of the first time-frequency resource in the plurality of time-frequency resources, including: the vacuum coating machine determines that a first number of time-frequency resources are needed for bearing the working state alarm information according to the information quantity of the working state alarm information; the vacuum coating machine determines a plurality of second time-frequency resources distributed around the time-frequency positions according to the time-frequency positions of the first time-frequency resources in the plurality of time-frequency resources; and the vacuum coating machine bears the working state warning information to a plurality of second time-frequency resources. It can be understood that, because the plurality of second time-frequency resources carrying the working state alarm information are distributed around the first time-frequency resources in a distributed manner, the probability of all resource transmission conflicts can be reduced, normal demodulation of data is not affected even if part of the resources conflict, and the stability of transmission can be improved.

Further, the reference signal is a reference signal belonging to a first antenna port of the vacuum coating machine, a second antenna port of the vacuum coating machine is an adjacent antenna port with the first antenna port, and the working state warning information is information sent through the second antenna port; or, part of the information of the working state alarm information is information sent through the second antenna port, and the other part of the information of the working state alarm information is information sent through the first antenna port. Adjacent antenna ports can be understood as indexing two adjacent beams, or beams that are adjacent in position. In other words, the reference signal and the operating state warning information are transmitted separately by two adjacent beams that are different. However, since the signal quality difference between two adjacent beams is usually not large, even if the reference signal and the two adjacent beams with different status alarm information are sent separately, the access network device is not affected to use the reference signal to normally demodulate the status alarm information. However, compared with the prior art that the reference signal and the working state alarm information are transmitted through the same beam, the reference signal and the working state alarm information are transmitted by two different adjacent beams respectively, so that an attacker cannot acquire information required by demodulation by monitoring only one beam, and the transmission safety can be improved.

Of course, the first antenna port and the second antenna port may not be limited to adjacent ports, and may be non-adjacent ports, as long as the channel demodulation performance of the two ports is close or similar.

Further, the working state warning information is information after the vacuum coating machine uses the key corresponding to the GF resource to carry out safety protection, so as to ensure the communication safety.

Optionally, the key corresponding to the GF resource is a key derived by the vacuum coating machine using at least one of the following as an input parameter; at least one item includes: at least part of parameters y1 and y2 until yn, at least part of parameters of a non-access NAS layer key of the vacuum coating machine, at least part of parameters of an access AS layer key of the vacuum coating machine, time-frequency positions of a plurality of second time-frequency resources, or port numbers of a first antenna port and/or a second antenna port. That is, the terminal may use the GF transmitted data/rule, or other keys, as an entry to generate a key, which is more difficult to be stolen by an attacker than in the conventional manner, so that the transmission security can be further ensured. It will be appreciated that the determination rules of at least one of the above may be configured by the access network device.

In a second aspect, a multiple communication control system for a vacuum coating machine is provided, the multiple communication control system is applied to the vacuum coating machine, the vacuum coating machine is connected to access network equipment, and the multiple communication control system is configured to: the working state of the vacuum coating machine is determined to be abnormal by monitoring the working state of the vacuum coating machine; responding to the abnormal working state of the vacuum coating machine, and sending working state warning information to access network equipment by the vacuum coating machine on each GF resource in N non-scheduling GF resources, wherein N is an integer greater than 1, and the working state warning information is used for indicating the abnormal working state of the vacuum coating machine.

Accordingly, the system is configured to: the vacuum coating machine sends working state warning information to the access network equipment on each GF resource in the N GF resources.

Optionally, the N GF resources are different GF resources, and the system is configured to: generating a random number #1 by the vacuum coating machine, wherein the value x1 of the random number #1 is a positive integer; the vacuum coating machine determines the y1 GF resource in the M GF resources as the 1 st selected GF resource according to x1mod N=y1; generating a random number #2 by the vacuum coating machine, wherein the value x2 of the random number #2 is a positive integer; and determining that the y2 th GF resource in the M GF resources is the GF resource in the 2 nd selection according to x2mod N=y2 by the vacuum coating machine, and so on until the yn GF resource in the M GF resources is the GF resource in the N selection, wherein yn is an integer from 1 to N, and the yn GF resource is different from the N-1 GF resource selected before the N GF resource in the N selection.

Further, the system is configured to: each GF resource in the N GF resources comprises a plurality of time-frequency resources distributed in a matrix, a first time-frequency resource in the plurality of time-frequency resources carries a reference signal, and the vacuum coating machine carries working state warning information to a second time-frequency resource in the plurality of time-frequency resources according to the position of the first time-frequency resource in the plurality of time-frequency resources.

Detailed Description

For convenience of understanding, technical terms related to the embodiments of the present invention are first described below.

Scheduling-free/dynamic Grant (GF) transmission:

GF transmission may be one of transmission schemes for reducing transmission delay in the future. GF transmission mainly includes two types, one is that the terminal completes uplink data transmission during a two-step random access (2-step RA) introduced in a random access (random access) such as a fifth generation (5th generation,5G) mobile communication system, that is, a New Radio (NR) system. The other is that the terminal directly performs uplink data transmission, for example, semi-persistent scheduling SPS (Semi-Persistent Scheduling) in long term evolution (long term evolution, LTE) system, transmission based on pre-configured uplink resources (preconfigured uplink resource, PUR), and Configured Grant (CG) transmission in NR. A common feature of both types of GF transmissions is that the terminal does not need to acquire the time-frequency resources and transmission parameters used for transmitting data by listening to the dynamic grant of the base station before transmitting uplink, but rather uses pre-configured time-frequency resources and transmission parameters, which are typically configured by the base station through higher layer signaling, such as system messaging (system information, SI) or User Equipment (UE) specific radio resource control (radio resource control, RRC) signaling. The two types of GF transmissions are different in that, for two-step random access, the terminal needs to send a random access preamble (preamble) to the base station when sending data, i.e., the data of the terminal and the random access preamble are in the same uplink message for uplink synchronization between the terminal and the base station. For the terminal to directly perform uplink data transmission, the terminal does not need to send a random access preamble to the base station, in other words, the scheme of direct transmission is more suitable for the situation that the terminal and the base station have completed uplink synchronization.

The technical scheme of the invention will be described below with reference to the accompanying drawings.

The terminal may be a terminal having a transceiver function, or a chip system that may be provided in the terminal. The terminal may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit (subscriber unit), a subscriber station, a Mobile Station (MS), a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device.

In the embodiment of the invention, the terminal is taken as an example of a vacuum coating machine.

The radio access network device (radio access network, RAN) device may be a device providing access to the terminal. For example, the RAN device may include: the next generation mobile vacuum coating machine multi-path communication control method system, such as a 6G access network device, such as a 6G base station, or the next generation mobile vacuum coating machine multi-path communication control method system, may also have other naming manners, which are all covered in the protection scope of the embodiments of the present invention, and the present invention is not limited in any way.

Fig. 2 is a schematic flow chart of a method according to an embodiment of the present invention. The multi-way communication control method of the vacuum coating machine is applicable to the multi-way communication control method of the vacuum coating machine, and relates to the interaction between application functions, edge internet of things proxy entities and operator networks. The specific flow is as follows:

s201, the vacuum coating machine determines that the working state of the vacuum coating machine is abnormal by monitoring the working state of the vacuum coating machine.

Before S201, the vacuum coating machine is connected to the access network device, in other words, the vacuum coating machine may choose to use conventional scheduling transmission with the access network device, for example, the access network device schedules the vacuum coating machine for uplink transmission or downlink transmission. On the basis, if emergency is met, the vacuum coating machine adopts GF transmission instead of conventional scheduling transmission under the condition that conventional scheduling transmission can be carried out.

The abnormal working state of the vacuum coating machine can be that the working temperature of the vacuum coating machine is too high, the working voltage or current is too high, the working program cannot be read/run, and the like, and the specific situation is not limited.

S202, responding to abnormal working state of the vacuum coating machine, and sending working state warning information to the access network equipment by the vacuum coating machine on each GF resource in the N GF resources.

The working state warning information can be used for indicating the abnormal working state of the vacuum coating machine.

The N GF resources may be a plurality of GF resources, i.e., N is an integer greater than 1. The N GF resources may be different GF resources. Each GF resource of the N GF resources includes a plurality of time-frequency resources distributed in a matrix. The time-frequency resource may be a Resource Block (RB) or a Resource Element (RE). The matrix distribution indicates that the plurality of time-frequency resources are consecutive time-frequency resources distributed in x×y. The REs distributed as 8 x 8, i.e. 8 rows of consecutive REs, each row comprising consecutive 8 REs for a total of 64 REs.

In one possible design, when the vacuum coating machine is connected to the access network device, the vacuum coating machine is configured with M GF resources by the access network device, where M is an integer greater than or equal to N, that is, the M GF resources include N GF resources. Thus, in response to an abnormal working state of the vacuum coating machine, the sending, by the vacuum coating machine, working state alert information to the access network device on each GF resource of the N non-scheduled GF resources may include: responding to the abnormal working state of the vacuum coating machine, the vacuum coating machine can select N GF resources from M GF resources, and send working state warning information to the access network equipment on each GF resource in the N GF resources. That is, the vacuum coating machine may default to be configured with more GF resources, such as M transmission resources, so that N resources to be used subsequently may be selected, so as to reduce the possibility of GF resource collision and reduce the influence of GF resource collision on transmission performance.

Optionally, the vacuum coating machine selects N GF resources from the M GF resources, and may include: generating a random number #1 by the vacuum coating machine, wherein the value x1 of the random number #1 is a positive integer; the vacuum coating machine determines that the y1 GF resource in M GF resources is the 1 st GF resource in the selection according to x1mod N=y1 (namely, the value of the obtained result is y1 by using x1 to carry out modular operation on N); generating a random number #2 by the vacuum coating machine, wherein the value x2 of the random number #2 is a positive integer; according to x2mod n=y2 (that is, the value of the result obtained by performing modulo operation on N by using x2 is y 2), the vacuum coating machine determines that the y2 nd GF resource in the M GF resources is the GF resource in the 2 nd selection, and so on until the yn GF resource in the M GF resources is the GF resource in the N selection (that is, the value of the result obtained by performing modulo operation on N by using xn is yn), wherein yn is an integer from 1 to N, and the yn GF resource is different from the N-1 GF resource selected before the GF resource in the N selection.

The embodiment of the invention does not limit the mode of generating the random number by the vacuum coating machine, for example, a pseudo-random algorithm can be adopted to generate the random number required by each modular operation, so that the network side can also generate the same random number by using the pseudo-random algorithm, thereby realizing the follow-up verification of the data of safety protection, such as decryption and integrity verification.

Further, each GF resource of the N GF resources includes a plurality of time-frequency resources distributed in a matrix, a first time-frequency resource of the plurality of time-frequency resources carrying a reference signal, and the method may further include: and the vacuum coating machine loads the working state warning information to a second time-frequency resource in the time-frequency resources according to the position of the first time-frequency resource in the time-frequency resources.

For example, the second time-frequency resource is a first number of a plurality of second time-frequency resources, and the vacuum coating machine carries the working state warning information to the second time-frequency resource in the plurality of time-frequency resources according to the time-frequency position of the first time-frequency resource in the plurality of time-frequency resources, including: the vacuum coating machine determines that a first number of time-frequency resources are needed for bearing the working state alarm information according to the information quantity of the working state alarm information; the vacuum coating machine determines a plurality of second time-frequency resources distributed around the time-frequency positions according to the time-frequency positions of the first time-frequency resources in the plurality of time-frequency resources; and the vacuum coating machine bears the working state warning information to a plurality of second time-frequency resources. For example, the position distribution of the plurality of second time-frequency resources may be determined according to a predetermined or preconfigured rule of the protocol, for example, taking the above-mentioned 8×8 REs as an example, the first time-frequency resource is RE (4, 4), that is, the RE of the 4 th row and the 4 th column, and the rule is that the plurality of second time-frequency resources need to be spaced 1 RE from the first time-frequency resource, so that the vacuum coating machine may determine a plurality of REs, such as RE (6.6), RE (2.2), and the like, spaced one RE from the surrounding of the RE (4, 4).

It can be understood that, because the plurality of second time-frequency resources carrying the working state alarm information are distributed around the first time-frequency resources in a distributed manner, the probability of all resource transmission conflicts can be reduced, normal demodulation of data is not affected even if part of the resources conflict, and the stability of transmission can be improved.

In summary, in the context of GF transmission, the vacuum coater may be configured to use multiple, e.g., N GF resources. When the vacuum coating machine has emergency information, such as working state warning information, to be reported, the vacuum coating machine can directly use each GF resource in N GF resources to send the working state warning information, namely N working state warning information. On one hand, the use of GF resources can reduce transmission delay, ensure that the network side can timely know the abnormal operation of the vacuum coating machine, on the other hand, multiplexing N GF resources can also reduce the influence of resource conflict, even if part of the resources conflict, the access network equipment can also receive working state alarm information through other non-conflicting GF resources, so that the influence of GF resource conflict on the transmission performance can be reduced, and the control stability of the vacuum coating machine is improved.
