All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. The cases of "target", "original", etc. are similar and will not be described in detail herein.

Fig. 1 is a flowchart of a connection switching method according to an embodiment of the present invention. The embodiment is applicable to the situation of automatically switching the connection mode between the cloud real machine server and the connection server, and is particularly applicable to the situation of automatically switching to the wireless connection mode to be connected with another connection server when the cloud real machine server cannot be connected with the connection server based on the wired connection mode. The method can be executed by the connection switching device provided by the embodiment of the invention, the device can be realized by software and/or hardware, and the device can be integrated on a cloud real machine proxy server.

Referring to fig. 1, the method of the embodiment of the present invention specifically includes the following steps:

S110, detecting the wired connection state of a first connection server based on the wired connection mode and a first connection server connected with the cloud real machine server.

The cloud proxy server (proxy) for executing the method of the embodiment of the invention is configured to be in communication connection with the first connection server, so that the wired connection state of the first connection server can be detected by the cloud proxy server, that is, whether the first connection server is connected with the cloud proxy server in a wired connection manner is detected, thereby determining whether the wired connection state of the first connection server is normal. In practical application, optionally, the wired connection mode may be realized by connecting a physical line with a communication function between a first connection server deployed with a first connection server and a cloud camera deployed with a cloud camera server.

In connection with the application scenario possibly related to the embodiment of the invention, for example, the communication connection between the cloud real machine proxy server and the first connection server can be realized based on WebSocket service; the first connection server may be built based on farmer; the first connection server may include a personal computer (Personal Computer, PC); the physical line may be a universal serial bus (Universal Serial Bus, USB); in general, the first connection server may be connected to at least one cloud computing device based on a wired connection, and the cloud computing device may be connected to one first connection server based on a wired connection.

And S120, under the condition that the abnormal wired connection state of the first connection service end is detected, aiming at a second connection service end which accesses the same wireless network with the cloud real machine service end, the second connection service end is scheduled to be connected with the cloud real machine service end based on a wireless connection mode corresponding to the wireless network, so that the connection mode of the cloud real machine service end is switched from the wired connection mode to the wireless connection mode.

The second connection server may be understood as a connection server different from the first connection server, that is, the first connection server and the second connection server are both connection servers, and they are named differently for distinguishing them, which is not a specific limitation on their essential content.

Under the condition that the wired connection state of the first connection server is detected to be abnormal, the first connection server cannot be connected with the cloud real machine server based on a wired connection mode, namely the cloud real machine server cannot be connected to any connection server at present, and the cloud real machine cannot effectively provide services. On the basis, the cloud real machine server and the second connection server are considered to be connected to the same wireless network, so that the cloud real machine proxy server can schedule the second connection server to enable the second connection server to be connected with the cloud real machine server based on a wireless connection mode (namely, a connection mode realized based on the wireless network), and the cloud real machine can be connected to a certain connection server, and service can be continuously provided.

Compared with the scheme that the cloud real machine server can only be connected to one connection server, i.e. depends on a single connection server (such as a PC), the technical scheme can automatically switch to a wireless connection mode to connect with another connection server when the cloud real machine server cannot be connected with the connection server based on a wired connection mode, i.e. the cloud real machine server can be connected to the connection server under any condition by switching the connection mode of the cloud real machine server, so that stable service of the cloud real machine is ensured.

In order to better understand the above technical solution, an exemplary description thereof is provided below in connection with specific examples. Illustratively, as shown in FIG. 2a, an operating system farmer of the PC is built: the PC deployed with the connection service end creates long connection with the cloud real machine through the USB, so that interaction between the control flow and the video flow is realized, and the USB connection (namely wired connection) is used as a main connection; the cloud real machine is connected with the same wireless network as the PC, and the wireless connection realized based on the wireless network is auxiliary connection; in other words, the USB connection and the wireless connection complement each other and are mutually backed up, so that the online rate of the cloud real machine is improved, and the stable service of the cloud real machine is ensured.

As shown in fig. 2b, a detection center monitor is set up: the detection center bit Yu Yunzhen for detecting the USB connection state of the connection server is used for proxy server, and the detection center for detecting the USB connection state of the cloud real machine server is located in the connection server. Detecting the USB connection state of the first connection server through a detection center in the cloud real machine proxy server, and further maintaining the current situation under the condition that the USB connection state of the first connection server is normal, namely the first connection server is connected with the cloud real machine server through the USB, so that efficient connection is guaranteed; correspondingly, under the condition that the USB connection state of the first connection server is abnormal, namely the first connection server cannot use the USB to connect with the cloud real machine server, the cloud real machine proxy server schedules the second connection server to be connected with the cloud real machine server through wireless, and therefore the effect of automatic tangent (namely switching from USB connection to wireless connection) is achieved.

On the basis, an optional technical scheme is that after detecting that the wired connection state of the first connection service end is abnormal, the connection switching method further comprises the following steps: generating a first warning message and sending the first warning message to the client, wherein the first warning message is used for warning that the wired connection state of the first connection server is abnormal; the scheduling of the second connection server to connect with the cloud real machine server based on the wireless connection mode corresponding to the wireless network includes: under the condition that a first wireless connection instruction returned by the client side aiming at the first warning message is received, responding to the first wireless connection instruction, and scheduling the second connection server side to be connected with the cloud real machine server side based on a wireless connection mode corresponding to the wireless network by setting the state of the cloud real machine server side relative to the second connection server side to be an on-line state.

Under the condition that the wired connection state of the first connection service end is abnormal, at least three solutions exist for ensuring stable service of the cloud real machine: the first step is that a physical line is connected between the cloud real machine and a second connection server provided with a second connection server by manpower, so that wired connection between the cloud real machine server and the second connection server is realized; secondly, the second connection server is scheduled to be connected to the cloud real machine server in a wireless mode through the cloud real machine proxy server, and therefore wireless connection between the cloud real machine server and the second connection server is achieved; third, the present situation is maintained, and the cloud computing device is applicable to the situation that the cloud computing device is not required to continuously provide services. Therefore, in the case of detecting the abnormal wired connection state of the first connection server, the cloud real machine proxy server can determine by itself or by related personnel whether to adopt any of the above three solutions to solve the abnormality. For the latter, the cloud real machine proxy server may send a first warning message for warning that the wired connection state of the first connection server is abnormal to the client, so that the relevant person determines according to the first warning message.

Further, the cloud real machine proxy server side receives the first wireless connection instruction returned by the client side for the first warning message, which indicates that the related personnel determine to adopt a second solution to solve the abnormality, and at this time, the effect of scheduling the connection of the second connection server side to the cloud real machine server side based on the wireless connection mode can be achieved by setting the state of the cloud real machine server side relative to the second connection server side to be in an online state, so that the cloud real machine can continue to provide services.

On the basis, optionally, the number of the second connection service ends is at least two, and the second connection service end is scheduled to be connected with the cloud real machine service end based on a wireless connection mode corresponding to the wireless network by setting the state of the cloud real machine service end relative to the second connection service end to be an on-line state, which comprises the following steps: determining wireless connection service ends with cloud real machine service ends mounted in at least two second connection service ends; and the state of the cloud real machine server side relative to the wireless connection server side is set to be an on-line state, and the wireless connection server side is scheduled to be connected with the cloud real machine server side based on a wireless connection mode corresponding to the wireless network.

In the case that at least two second connection service ends exist, in order to wirelessly connect the cloud real machine service end to a certain second connection service end, related personnel can mount the cloud real machine service end on a certain second connection service end in the at least two second connection service ends through operation, and specifically can mount the cloud real machine on a certain PC. In this way, the cloud real machine proxy server can determine the wireless connection server on which the cloud real machine server is mounted from at least two second connection servers, and then set the state of the cloud real machine server relative to the wireless connection server to be an on-line state, so that wireless connection between the cloud real machine server and the wireless connection server (namely, a certain second connection server) is realized.

Fig. 3 is a flowchart of another connection switching method according to an embodiment of the present invention. The present embodiment is optimized based on the above technical solutions. In this embodiment, optionally, the connection switching method may further include: under the condition that a second warning message sent by the first connection server is received, the second connection server is scheduled to be connected with the cloud real machine server based on a wireless connection mode; the second warning message is generated by the first connection server under the condition that the wired connection state of the cloud real machine server is detected to be abnormal. Wherein, the explanation of the same or corresponding terms as the above embodiments is not repeated herein.

Referring to fig. 3, the method of this embodiment may specifically include the following steps:

S210, detecting the wired connection state of a first connection server based on the wired connection mode and a first connection server connected with the cloud real machine server.

S220, when the abnormal wired connection state of the first connection service end is detected, and/or a second warning message sent by the first connection service end is received, aiming at a second connection service end which accesses the same wireless network with the cloud real machine service end, the second connection service end is scheduled to be connected with the cloud real machine service end based on a wireless connection mode corresponding to the wireless network, so that the connection mode of the cloud real machine service end is switched from the wired connection mode to the wireless connection mode, wherein the second warning message is generated by the first connection service end when the abnormal wired connection state of the cloud real machine service end is detected.

The cloud real machine server and the first connection server are connected in a wired connection manner, so that the first connection server can detect the wired connection state of the cloud real machine server, for example, the detection center in the first connection server shown in fig. 2b detects the wired connection state of the cloud real machine server. On the basis, under the condition that the first connection server detects that the wired connection state of the cloud real machine server is abnormal, a second warning message for warning the wired connection state of the cloud real machine server can be generated, and the second warning message is sent to the cloud real machine proxy server.

And under the condition that the cloud real machine proxy server receives the second warning message, determining that the wired connection state of the cloud real machine server is abnormal, namely that the wired connection between the first connection server and the cloud real machine server is abnormal, and in order to ensure stable service of the cloud real machine, the second connection server can be scheduled to be connected with the cloud real machine server based on a wireless connection mode, so that the cloud real machine server is connected to a certain connection server again.

According to the technical scheme provided by the embodiment of the invention, the cloud real machine proxy server can determine the connection condition between the first connection server and the cloud real machine server through the related data after the wired connection state of the cloud real machine server is detected by the first connection server, and the connection condition is combined with the connection condition detected by the cloud real machine proxy server, so that the cloud real machine server can be connected to a certain connection server under any condition from different aspects, and stable service of the cloud real machine can be better ensured.

On the basis, an optional technical scheme, after receiving the second warning message sent by the first connection server, the connection switching method may further include: sending a second warning message to the client; the scheduling second connection service end is connected with the cloud real machine service end based on a wireless connection mode, and comprises the following steps: and under the condition that a second wireless connection instruction returned by the client side aiming at the second warning message is received, responding to the second wireless connection instruction, and scheduling the second connection server side to be connected with the cloud real machine server side based on a wireless connection mode by setting the state of the cloud real machine server side relative to the second connection server side to be an on-line state. The specific implementation process of the technical scheme is similar to the implementation process of the technical scheme related to the first warning message, and is not repeated here. Therefore, the cloud real machine proxy server plays a role of a bridge, and opens the network where the client is located and the connection server, so that data interaction between the client and the connection server is realized.

Fig. 4 is a flowchart of another connection switching method according to an embodiment of the present invention. The present embodiment is optimized based on the above technical solutions. In this embodiment, optionally, the cloud real machine proxy server belongs to at least two candidate proxy servers, and the connection switching method further includes: receiving a first connection request sent by a client through a load balancing server, wherein the load balancing server is used for determining a candidate proxy server to be connected to the client from at least two candidate proxy servers according to a cloud real machine identifier in the first connection request, forwarding the first connection request to the determined candidate proxy server, and the cloud real machine identifier is used for identifying the cloud real machine server; and responding to the first connection request, and connecting with the client. Wherein, the explanation of the same or corresponding terms as the above embodiments is not repeated herein.

Referring to fig. 4, the method of this embodiment may specifically include the following steps:

S310, detecting the wired connection state of a first connection server based on the wired connection mode and a first connection server connected with the cloud real machine server.

And S320, under the condition that the abnormal wired connection state of the first connection service end is detected, aiming at a second connection service end which accesses the same wireless network with the cloud real machine service end, the second connection service end is scheduled to be connected with the cloud real machine service end based on a wireless connection mode corresponding to the wireless network, so that the connection mode of the cloud real machine service end is switched from the wired connection mode to the wireless connection mode.

S330, receiving a first connection request sent by the client through the load balancing server, and responding to the first connection request to connect with the client, wherein the load balancing server is used for determining a candidate proxy server to be connected to the client from at least two candidate proxy servers according to a cloud real machine identifier in the first connection request, forwarding the first connection request to the determined candidate proxy server, and the cloud real machine identifier is used for identifying the cloud real machine server.

In the case that at least two candidate proxy service (proxy) ends exist, for a current connection service end currently connected with a cloud service end in the first connection service end and the second connection service end, a cloud service proxy service end to be connected with the current connection service end can be determined from the at least two candidate proxy service ends according to a cloud service identifier for identifying the cloud service end (or a cloud service), and then connection between the current connection service end and the cloud service proxy service end is established, for example, connection between the current connection service end and the cloud service proxy service end is established through WebSocket service. In practical application, optionally, under the condition that the cloud real machine proxy server is interrupted, the current connection server can automatically select other candidate proxy servers from the at least two candidate proxy servers to complete bridging, so that the limitation of point-to-point network docking of WebSocket service is broken, and stable service of the cloud real machine server connected to the current connection server is ensured. Alternatively, the cloud machine identifier may be represented by a serial number, an internet protocol (Internet Protocol, IP), or a port of the cloud machine, which is not specifically limited herein.

On the basis, in order to realize data interaction between the client and the cloud real machine server, the client can be connected to the cloud real machine proxy server, so that the data interaction between the client and the cloud real machine proxy server is realized through the path of the cloud real machine proxy server. Because the cloud real machine proxy server is determined from at least two candidate proxy servers according to the cloud real machine identification, the client can send the first connection request to the load balancing server, and the load balancing server can determine the candidate proxy server to be connected to the client from the at least two candidate proxy servers according to the cloud real machine identification in the first connection request and forward the first connection request to the candidate proxy server. Therefore, under the condition that the cloud real machine proxy server receives the first connection request, the cloud real machine proxy server is the candidate proxy server to be connected to the client side in the at least two candidate proxy server sides, and therefore the cloud real machine proxy server can respond to the first connection request to be connected to the client side, for example, connection between the cloud real machine proxy server and the client side is achieved through WebSocket service, the effect that the client side and the cloud real machine server side are connected to the same candidate proxy server side is achieved, and data interaction between the client side and the cloud real machine server side is achieved.

On the basis, in combination with the application scenario possibly related to the embodiment of the invention, optionally, the data interaction between the client and the cloud real machine server can be realized through the following steps: receiving a video stream sent by a cloud real machine server through a first connection server or a second connection server, and forwarding the video stream to a connected client so that the client displays the received video stream, wherein the video stream can embody content displayed on a display interface of the cloud real machine; and/or receiving a control flow sent by the connected client, and sending the control flow to a current connection server currently connected with the cloud real machine server in the first connection server and the second connection server, so as to control the cloud real machine deployed with the cloud real machine server through the current connection server based on the received control flow, for example, clicking and/or sliding a target object on the cloud real machine.

In order to better understand the above technical solution, an exemplary description thereof is provided below in connection with specific examples. For example, referring to fig. 5, here, an example is a cloud server deployed on a circled cloud server, where the cloud server is connected to a 3 rd connection server, and the 3 rd connection server is connected to a2 nd candidate proxy server. On the basis, a certain client in the 3 clients sends a first connection request corresponding to the cloud real machine to a load balancing server (Nginx) through a firewall, the load balancing server carries out hash calculation on a serial number in the first connection request, and then the first connection request is forwarded to the 2 nd candidate proxy server according to an obtained hash calculation result so that the 2 nd candidate proxy server is connected with the client. The client and the 3 rd connection server (i.e. the connection server connected with the cloud real machine server) are connected to the same candidate proxy server (i.e. the 2 nd candidate proxy server), so that data interaction between the client and the cloud real machine server can be realized.

According to the technical scheme, the client sends a first connection request containing a cloud real machine identifier (used for identifying the cloud real machine server to be connected) to the load balancing server; the load balancing server can determine a candidate proxy server to be connected with the client from at least two candidate proxy servers according to the cloud real machine identification in the first connection request, and forward the first connection request to the candidate proxy server; therefore, under the condition that the cloud real machine proxy server receives the first connection request, the cloud real machine proxy server is connected with the cloud real machine server, and after connection between the cloud real machine proxy server and the client is established, the effect that the client and the cloud real machine server are automatically connected to the same candidate proxy server can be achieved, which is a necessary precondition for data interaction between the client and the cloud real machine server.

An optional technical solution, the above connection switching method further includes: receiving a second connection request sent by the connectable service end through the load balancing service end, and responding to the second connection request to connect with the connectable service end so as to detect the wired connection state of the connected connectable service end or schedule the connected connectable service end; the connectable service end comprises a first connection service end or a second connection service end, and the load balancing service end is used for determining a candidate proxy service end to be connected to the connectable service end from at least two candidate proxy service ends according to the cloud real machine identification in the second connection request and forwarding the second connection request to the determined candidate proxy service end.

The connection between the candidate proxy server and the connectable server can also be completed through the load balancing server, so that the cloud real machine server and the client can be connected to the same candidate proxy server. Specifically, the connectable server may generate and send a second connection request according to a cloud real machine identifier corresponding to the cloud real machine server connected to the connectable server, and then the load balancing server may forward the second connection request to the corresponding candidate proxy server according to the cloud real machine identifier in the received second connection request. On the basis, after the cloud real machine proxy server side in the at least two candidate proxy server sides receives the second connection request, the cloud real machine proxy server side can be connected with the connectable server side, so that the connection process between the connectable server side and a certain candidate proxy server side is realized, and further detection operation or scheduling operation can be executed.

In order to better understand the above-described respective technical solutions as a whole, an exemplary description thereof is given below in conjunction with specific examples. For example, referring to the cloud real machine platform shown in fig. 6, the cloud real machine platform includes at least two cloud real machine proxy servers (herein, referred to as a candidate proxy server in the foregoing, and not specifically referred to as a candidate proxy server), a load balancing server, at least two connection servers, at least two cloud real machines (i.e., at least two cloud real machine servers), and a client (not shown in fig. 6, for displaying UI interfaces).

On the basis, each cloud real machine server is connected with a certain connection server based on a USB connection mode, and is connected with the same wireless network with each connection server, so that when the USB connection is abnormal, the cloud real machine server can be switched to the wireless connection mode to be connected with the certain connection server. A cloud real machine server can be connected to a connection server, and a connection server can be connected with one or more cloud real machine servers. For each connection server, the connection server can send a second connection request to the load balancing server according to the serial number of the cloud real machine mounted on the connection server, so that the load balancing server forwards the second connection request to a certain cloud real machine proxy server according to the serial number, and connection between the cloud real machine proxy server and the connection server is completed.

And under the condition that a related person needs to control a certain cloud real machine through the client, the client can send a first connection request to the load balancing server based on the serial number of the cloud real machine, so that the load balancing server forwards the first connection request to a certain cloud real machine proxy server according to the serial number, and the connection between the cloud real machine proxy server and the client is completed. The cloud real machine and the client are connected to the same cloud real machine proxy server, namely, the internal network where the client is located is communicated with the office network where the client and the client are connected through the bridge of the cloud real machine proxy server, so that data interaction between the cloud real machine and the client is realized.

From the above, the above-mentioned cloud real machine platform belongs to a distributed platform, when there is an expansion demand, the connection server can be directly added, and the newly added connection server is directly connected to a certain cloud real machine proxy server, so that there is no need to redeploy a cloud real machine proxy server, and the expansibility is better.

Optionally, on the basis of the above device, the device may further include:

The first warning message sending module is used for generating a first warning message after detecting that the wired connection state of the first connection server is abnormal, and sending the first warning message to the client, wherein the first warning message is used for warning that the wired connection state of the first connection server is abnormal;

the connection switching module 420 may include:
