Detailed Description

The core of the application is to provide a data scanning optimization method, which can reduce the network flow of a high-speed scanner in the using process and improve the scanning speed of the high-speed scanner in a desktop cloud system; at the other core of the application, a data scanning optimization device, a system, a computer device and a readable storage medium are provided.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic connection diagram of a conventional desktop cloud scanning system, where the desktop cloud system uses a high-speed scanner as a peripheral device, data is forwarded through a desktop cloud terminal, and a timing diagram of an original scanning control flow is shown in fig. 2, where a box terminal is the desktop cloud terminal in fig. 1. Because the scanning instruction which can be identified by the existing scanner takes the short line as an identification unit, the integral scanning instruction of a long segment of data needs to be divided into a plurality of short lines and sent to the scanner one by one for scanning one by one. The network transmission performance is much lower than that of the USB protocol, data is forwarded through this transmission path, and the high-speed scanner solution on the desktop cloud system is limited by network transmission, which presents several main drawbacks as follows:

1. the scanning speed is slow and the experience is poor compared with that on a physical PC.

2. During scanning, a large network bandwidth is occupied, and the service use of other desktop cloud systems is influenced.

The application provides a data scanning optimization method aiming at a desktop cloud system (mainly referring to a virtual operating system, similar to an operating system such as a win10\ win7\ ubuntu running on a virtual machine), the method can greatly reduce the network flow of a high-speed scanner in the using process, and can effectively solve the problem of low transmission efficiency caused by too frequent interaction of high-speed scanning control instructions, so that the scanning speed of the high-speed scanner in the desktop cloud system is increased, and the use experience of the high-speed scanner on the desktop cloud system is improved.

The first embodiment is as follows:

referring to fig. 3, fig. 3 is a flowchart of a data scanning optimization method provided in the present embodiment; the method mainly comprises the following steps:

and step s110, intercepting a scanning control instruction which is sent to the desktop cloud terminal by the virtual machine.

The scan control instruction refers to a scan control instruction for data requested to be scanned, and the scan control instruction needs to be transmitted to the desktop cloud terminal through a network, so the scan control instruction is a network control instruction according to a network transmission protocol.

The scanning control instruction can be a complete scanning instruction generated according to a complete scanning requirement, namely an integral data scanning instruction before splitting a short-line scanning instruction according to a high-speed scanner in a traditional scanning scheme; the partial data scanning sub-command for controlling the scanning process of the scanner may be further generated according to the complete scanning requirement, which is not limited herein. For example, a user designates to scan data of the second segment to the eighth segment, and in the conventional method, the virtual machine needs to split the data scanning instruction of the second segment to the eighth segment into a plurality of short-line scanning instructions recognizable by the high-speed scanner, including, for example, a data scanning instruction of a first line of the second segment, a data scanning instruction of a second line of the second segment, and the like. It should be noted that the scan control instruction mainly has the main function of generating a subsequent simulation USB instruction, and when the intercepted scan control instruction is a complete integral scan instruction, the simulation instruction can be generated directly according to the intercepted scan control instruction; when the intercepted scan control instruction is not a complete integral scan instruction but a certain sub-instruction, the integral scan instruction needs to be restored in the generation process of the simulation instruction so as to facilitate the control of integral scanning.

The desktop cloud terminal refers to a terminal device accessed to a desktop cloud system, and may be an arm terminal (android system), an x86 terminal (linux system), a pc client (windows system), and the like.

The purpose of instruction interception is to obtain the specified data scanning requirement, meanwhile, the splitting and sending of the instructions by the virtual machine are avoided, and the occupation of time resources and network bandwidth resources in the process that a plurality of split small instructions are transmitted to the desktop cloud terminal one by one through the network is avoided. In the embodiment, the times of network instruction transmission are reduced, the whole process is eliminated, the transmission process of a plurality of small network instructions is omitted, and the repeated establishment of network channels and the long-term occupation of network bandwidth in the network instruction transmission process are greatly reduced.

In this embodiment, a specific instruction interception implementation manner is not limited, and reference may be made to an instruction interception implementation manner in the related art, which is not described herein again.

And step s120, generating a simulation scanning USB control instruction according to the scanning control strategy of the high-speed scanner and the USB protocol according to the scanning control instruction.

In order to ensure the normal identification of the high-speed scanner, the present embodiment follows the command identification strategy of the conventional high-speed scanner, generates the simulation command according to the scan control strategy of the high-speed scanner and the USB protocol based on the data scan overall control command,

because the scanning control command is generated according to the scanning control strategy of the high-speed scanner, the traditional high-speed scanner can also be directly identified, and the traditional high-speed scanner can be directly called. Meanwhile, in order to continue to use an instruction transmission protocol between the desktop cloud terminal and the high-speed scanner and realize direct calling of the traditional high-speed scanner, the generated simulation instruction is a simulation instruction based on a USB protocol.

Specifically, the generation process of the simulation instruction may refer to the generation process of the virtual machine scanning instruction in the conventional desktop cloud system, and the main difference is that the virtual machine generates the network protocol transmission instruction, and the USB protocol transmission instruction is generated in this embodiment, and other aspects, such as specifying the segmentation mode of the scanning data, may refer to the conventional implementation scheme, and are not described herein again.

And step s130, calling the USB controller to send scanning instructions to the high-speed scanner one by one according to the sending rule of the analog scanning control instruction.

The USB controller is arranged in the desktop cloud terminal, the process of transferring the USB controller to transmit the simulation instruction to the connected high-speed scanner can refer to the process of directly transferring the USB controller to transmit the instruction by the desktop cloud terminal in the traditional method, only the transmitted instruction needs to be replaced by the scanning instruction generated by the simulation instruction in the application, and the description is omitted here.

After receiving the instruction, the high-speed scanner scans data according to a conventional scanning scheme, and the specific process may refer to the introduction of the related art.

Based on the introduction, the data scanning optimization method provided by the embodiment intercepts the data scanning overall control instruction which is sent to the desktop cloud terminal by the virtual machine; generating a simulation scanning control instruction according to a scanning control strategy of the high-speed scanner according to the data scanning overall control instruction; the USB controller is called to send the scanning commands to the high-speed scanner one by one according to the sending rule of the simulation scanning control command, the scanning commands are turned into a whole, the command sending times between the virtual machine and the desktop cloud terminal are greatly reduced, the interaction times are reduced, the control flow is simplified, the network transmission limitation is reduced, and the resource loss caused by the fact that the virtual machine sends all the scanning control commands to the desktop cloud terminal one by one through the network is effectively reduced.

Example two:

in contrast to the first embodiment, the present embodiment is further introduced on the basis of the first embodiment, mainly from the perspective of the sending mechanism of the returned scan data.

Because the scanning instruction received by the high-speed scanner is an instruction based on short lines, scanning data of each short line can be obtained after scanning every time, in the traditional mode, the scanning data of each short line can be directly forwarded to a virtual machine through a terminal in a desktop, in order to avoid excessive occupation of network bandwidth in multiple data sending processes in a data feedback process, reduce network resource loss and improve the overall operation efficiency of the system, preferably, after a USB controller is called to send the scanning instruction to the high-speed scanner one by one according to a sending rule of an analog scanning control instruction, zero-rounding of the data can be further realized according to the following steps:

(1) Acquiring scanning data returned to the USB controller by the high-speed scanner;

(2) Sorting the scanned data according to the return sequence to generate complete scanned data;

(3) And transmitting the complete scanning data to the virtual machine through a network transmission interface.

The purpose of data arrangement is to arrange a plurality of scanning data returned for a plurality of times together to generate one-minute complete scanning data. Through data sorting, the multiple independent forwarding process of the multiple scanning data is adjusted to be single forwarding of the multiple scanning data, and excessive occupation of network bandwidth in the process of sending the multiple data to the virtual machine is avoided.

The process of data sorting may include a process of data splicing according to the sequence of the return time, and may further include further optimization of the scanned data, such as noise removal, etc., where the specific implementation process of data sorting is not limited, and may be set according to the actual data scanning and viewing needs.

Of course, multiple independent forwarding may also be performed according to the conventional data return mechanism, which is not limited in this embodiment.

Example three:

based on the second embodiment, in order to further increase the data network transmission speed, before the complete scan data is transmitted to the virtual machine through the network transmission interface, the complete scan data can be further subjected to data compression processing to obtain compressed data; accordingly, the process of transmitting the complete scan data to the virtual machine through the network transmission interface specifically includes: and transmitting the compressed data to the virtual machine through the network transmission interface.

By compressing the sorted data to be transmitted, the data volume to be transmitted is reduced, and the network flow loss is reduced.

In addition, in order to further improve the security of data network transmission, before the complete scanning data is transmitted to the virtual machine through the network transmission interface, the complete scanning data can be further subjected to data encryption processing to obtain encrypted data; accordingly, the process of transmitting the complete scan data to the virtual machine through the network transmission interface specifically includes: and transmitting the encrypted data to the virtual machine through the network transmission interface.

The arrangement data to be transmitted is encrypted, and data ciphertext is transmitted, so that the threat to the data security can be directly checked after the data is stolen in the network transmission process, and the data security is improved.

It should be noted that, in the data compression process and the data encryption process in this embodiment, both the data compression and data encryption implementation processes in the related art can be referred to, and the specifically adopted compression algorithm and encryption algorithm, or the called compression tool or encryption tool is not limited, and data compression and data encryption can be implemented. In addition, if the data is processed for the second time by means of data compression or data encryption, in order to ensure normal identification of the data, the receiving end (virtual machine) receives the data and then performs data decompression or data decryption correspondingly, which is not described herein again.

Example four:

based on the above embodiment, because of the wide variety of the current high-speed scanners, there are situations that some high-speed scanners cannot identify the simulation instruction, and the like, in order to avoid system abnormality caused by a contradiction between the high-speed scanner and a protocol in a data scanning process and ensure a scanning effect, preferably, before intercepting a data scanning overall control instruction that a virtual machine intends to send to a desktop cloud terminal, the following steps may be further performed:

(1) Extracting equipment information of the high-speed scanner;

(2) Judging whether the high-speed scanner is a preset optimizable high-speed scanner or not according to the equipment information; if yes, jumping to step s110; if not, executing the following step (3);

(3) And controlling data interaction between the desktop cloud terminal and the high-speed scanner according to the original data scanning rule.

The method mainly comprises the steps of setting a judgment standard of a preset optimizable scanner according to actual scanning conditions, and particularly distinguishing types of the high-speed scanners by configuring vid \ pid of the corresponding scanners.

Example five:

the type of the scan control instruction in the above embodiment is not limited, and may be an overall scan instruction or a scan sub-instruction, in the above embodiment, the scan control instruction is mainly taken as the overall scan instruction for example, and in the present embodiment, the generation process of the simulation instruction is taken as an example when the scan control instruction is the first sub-instruction.

The first sub-instruction refers to a first instruction in the sub-instructions which is generated according to the complete original scanning control instruction and is convenient for the scanner to identify.

The method has the advantages that the first sub-instruction is sent firstly when the virtual machine sends the control instruction to the desktop cloud terminal, timeliness is high, meanwhile, compared with the acquisition of the integral scanning control instruction, the acquisition of the first sub-instruction only needs to monitor data output of the virtual USB controller in the virtual machine, and the implementation mode is simple.

When the scan control command is the first sub-command, according to the scan control command, the process of generating the simulated scan USB control command according to the scan control policy of the high-speed scanner and the USB protocol in step s120 specifically includes:

and generating an analog scanning USB control instruction according to the scanning control strategy of the high-speed scanner and the USB protocol according to the predicted scanning control instruction.

The instruction prediction process is according to a preset instruction prediction rule instruction, and the instruction prediction rule may be freely set according to an actual scanning requirement, or a default prediction rule may be set, and the like, which is not limited herein. For example, default prediction rules may be set: and taking all data behind the data contained in the first sub-instruction as an object to be scanned and the like.

The command prediction process is equivalent to the restoration of the complete scanning control command according to the first sub-command, and because the restoration process is a prediction restoration process, a certain error may exist relative to an actual complete scanning control strategy, so as to avoid the difference between request data and feedback data and improve user experience, preferably, after scanning commands are sent to the USB controller one by one according to a sending rule of a simulated scanning USB control command, if returned scanning data are received, the scanning data to be called by an application program in the virtual machine are further screened out; and sending the data obtained after screening to an application program. For example, when the scanned data is data of the second to tenth rows, and the actual user designates to scan the data of the second to ninth rows through the application program, the data of the second to ninth rows are screened out from the returned data and returned to the application program, so that the user calls the application program to obtain the scanned data.

Example six:

in order to deepen understanding of the content provided in the foregoing embodiment, the implementation flow of the overall optimization scheme in this embodiment is illustrated as an example, and other data scanning schemes based on this application can refer to the description of this embodiment and are not described herein again.

Fig. 4 is a schematic flow chart of a data scanning process provided in this embodiment, where the scanning process mainly includes the following processes:

1. the high speed scanner data is parsed.

The high-speed scanner transmits data through a USB, and can analyze a corresponding USB transmission control instruction by combining with a scanner control protocol.

2. It is detected whether it is an optimizable high speed scanner.

And judging whether the high-speed scanners with the same scanning protocol as the Canon series high-speed scanner and the Kodak series high-speed scanner by configuring the vid \ pid of the corresponding scanner.

3. The optimization process is not carried out:

if the scanning control command is not the optimized scanner, the scanning control command is not processed and only forwarded according to the original flow;

4. a start scan instruction is detected.

Since the driving of the high-speed scanner initially sets the corresponding scanning parameters to the device and then starts scanning the paper, a detection is made to determine whether to start scanning

5. A scan instruction is simulated.

The control instruction of the high-speed scanner is simulated through the USB control packet to control the scanner to scan, the step is to simplify the scheme of terminal measurement of the scanning control flow, and the scanning instruction is obtained by calling the scanning protocol of the high-speed scanner.

6. And acquiring scanning data, compressing and sending the scanning data to a server.

By sending a control instruction (USB data packet) to the high-speed scanner, the high-speed scanner can provide corresponding paper image data (USB data packet) scanned by the scanner, and the data is effectively compressed after the image data is obtained, so that the network data transmission flow is reduced.

The virtual machine receives data sent by the desktop cloud terminal through the network, obtains effective paper data scanned by the high-speed scanner after decompression, and caches the effective data. The drive in the virtual machine can sequentially send out data fetching requests, and at the moment, the server fetches data from the caches and returns the data to the software in the virtual machine for use;

7. it is detected whether the scanning is completed.

A corresponding instruction is available in the scanning control instruction to detect whether paper needs to be scanned in the high-speed scanner, and the high-speed scanner returns corresponding state information after sending; and when the dyed-back state information shows that the scanning is finished, finishing the current flow.

According to the data scanning method provided by the embodiment, the scanning data is obtained in a mode of simulating the scanning data instruction and is subjected to proxy forwarding, so that instruction interaction between the server and the desktop cloud terminal is reduced, the network transmission flow is reduced through data compression, and the scanning speed of the high-speed scanner on the desktop cloud scheme is greatly improved.

Example nine:

in order to deepen understanding of the data scanning optimization device divided into the first component and the second component, which are respectively arranged in the virtual machine and the desktop cloud terminal and described in the eighth embodiment, in this case, the system structure and the process schematic in this case are described in this embodiment.

Fig. 8 is a schematic structural diagram of a system provided in this embodiment, where the system mainly includes: the system comprises a virtual machine, a desktop cloud terminal and a high-speed scanner.

Specifically, the virtual machine includes an application program that needs to scan data, a virtual USB controller used for realizing sending of a scan control instruction, and a first component.

The virtual machine and the desktop cloud terminal are in data transmission through a network, and the desktop cloud terminal comprises a second component and a USB controller.

The desktop cloud terminal and the high-speed scanner realize data transmission through a USB protocol.

Fig. 9 shows a sequence diagram of data flow among the three devices, and the data flow interaction process among the three devices is mainly as follows:

the detection is performed because the driving of the high-speed scanner initially sets the corresponding scanning parameters to the apparatus and then starts scanning the paper. When a start scanning instruction is detected, the subsequent flow is started.

And transmitting an instruction for starting scanning to the desktop cloud terminal through network connection between the virtual machine and the desktop cloud terminal, and informing the desktop cloud terminal of starting simulating scanning data.

The desktop cloud terminal simulates a control instruction of the high-speed scanner through the USB control packet to control the scanner to scan, and the scanning instruction is generated according to a scanning protocol for calling the high-speed scanner.

By sending a control instruction (USB packet) to the high-speed scanner, the high-speed scanner provides the desktop cloud terminal with the corresponding paper image data (USB packet) scanned by the scanner.

Whether scanning is finished or not is detected, a corresponding instruction exists in the scanning control instruction to detect whether paper needs to be scanned or not in the high-speed scanner, and the high-speed scanner returns corresponding state information after the scanning control instruction is sent;

after scanning is finished, the desktop cloud terminal effectively compresses the image data after acquiring the image data, so that network data transmission flow is reduced, and the image data is sent to the virtual machine.

And the Virtual Machine (VMP) receives data sent by the desktop cloud terminal through the network, decompresses the data to obtain effective paper data scanned by the high-speed scanner, and caches the effective data.

In the data scanning optimization system provided in this embodiment, the virtual machine analyzes the high-speed scanner instruction to notify the desktop cloud terminal, the desktop cloud terminal simulates the high-speed scanner instruction to control high-speed scanning and obtains data to send to the virtual machine, the virtual machine caches the data and proxies the data to software used in the virtual machine (for example, plug-in components of the scanner are called in a web service system of a client), so that a control flow of the scanner is optimized; meanwhile, the desktop cloud terminal acquires the scanning data of the high-speed scanner, compresses the scanning data and transmits the compressed scanning data to the server side, and therefore network flow occupied by the high-speed scanner on the desktop cloud platform is reduced.
