Background

The scanning device is a high-tech product with closely combined optical, mechanical, electronic and software technologies, and is another main computer input device following a mouse and a keyboard. Since birth, the scanning device can process the original manuscript data to the two-dimensional codes in recent years, and further realize the management, use, storage and output of the information.

A typical scanning device is a Personal Digital Assistant (PDA), which may also be called a handheld mobile terminal, and is widely used in industries such as logistics, warehousing, retail, and the like for identifying information such as two-dimensional codes. When the PDA works, the information such as the two-dimensional code and the like needs to be identified through a scanning engine, and one PDA may need to use different scanning engines according to different application scenes. Because different scanning engines need different Software Development Kits (SDKs) to drive, a user needs to select a proper SDK according to the currently used scanning engine, and the method is not only complicated in flow, but also requires the user to have certain professional knowledge and is poor in operability. Therefore, how to enhance the operability of the scanning device is a problem that needs to be solved currently.

Detailed Description

The technical solutions provided in the present application will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a scanning system suitable for use in the present application. The scanning system includes a cloud 110 and a PDA 120.

The cloud 110 is, for example, a server on which a software platform using virtualization technology is installed, and the software platform integrates a plurality of functions such as search, download, use, management, backup, and the like. Through the platform, various common software can be packaged in an independent virtualization environment, so that application software and an operating system are decoupled, and the purpose of green software use is achieved.

The PDA120 can accelerate the processing speed of information and improve the accuracy of information processing, and its basic principle is: a commodity document (unit price, department, discount.) is created in a computer file of PDA120, and the commodity document can be directly displayed in PDA120 after a barcode on the commodity is read in by an optical reading device (e.g., a dock broom).

The PDA120 can convert the two-dimensional code or barcode on the commodity into information that can be identified by a computer according to a preset decoding manner, so as to manage, use, store and output the information, for example, the information can be displayed to a user for the user to process.

PDA120 may communicate with cloud 110 as indicated by the double-headed arrow in fig. 1. The communication method may be wireless communication or wired communication. For example, PDA120 may communicate with cloud 110 via fiber optics, or via a cellular network. The communication method between PDA120 and cloud 110 is not limited in this application.

The scanning system shown in fig. 1 is only one example of a scanning system applicable to the present application, and the scanning system applicable to the present application is not limited thereto. For example, PDA120 and cloud 110 may also be cell phones or tablet computers.

In general, the PDA used by the user is a factory-set device, and the user is not required to perform setting. However, in some cases, the user needs to reset the PDA.

For example, the factory setting of the PDA is a scan engine and a scan configuration of a two-dimensional code, when a user needs to scan a barcode, the scan configuration corresponding to the scan engine may need to be reset, and if the user makes a setting error, a scan failure may be caused.

For another example, when the PDA has an upgradeable scanning configuration, the PDA may not be able to achieve better use without upgrading the scanning configuration of the PDA.

It is necessary for the user to have some expertise in setting up the PDA or upgrading the scanning configuration, resulting in poor operability of the existing PDA.

The application provides a scanning method and scanning equipment, which can enhance the operability of the scanning equipment and reduce the difficulty of better code scanning effect experienced by a user.

The scanning method 200 provided by the present application is shown in fig. 2, and the method 200 may be executed by a terminal device or a chip in the terminal device. The following description will take the example where the execution device of the method 200 is a PDA. The method 200 comprises the following steps:

s210, determining the type of the scanning engine.

The PDA may determine, via the hardware node, which type of scan engine is currently in use. For example, after the PDA is powered on, the processor scans each hardware node on the PDA, and determines the type of the scanning head through hardware identifiers such as a hardware serial number; then, the type of the scanning engine matched with the scanning head is determined according to the type of the scanning head.

S220, determining a target scanning configuration from a plurality of scanning configurations according to the type of the scanning engine, wherein the target scanning configuration is the scanning configuration matched with the type of the scanning engine in the plurality of scanning configurations.

The matching relationship between the plurality of scan configurations and the scan engine may be stored in the PDA in advance, for example, the PDA may scan using two scan engines, which are scan engine a and scan engine B, respectively, the scan configuration matched with the scan engine a is scan configuration 1, scan configuration 2 and scan configuration 3, the scan configuration matched with the scan engine B is scan configuration 2 and scan configuration 4, and the matching relationship may be stored in the PDA in the form of a table. Alternatively, the matching relationship between the scanning configuration and the scanning engine may be pre-stored in other places, and acquired into the PAD through various communication methods when necessary.

After the PDA determines the type of scan engine currently in use (e.g., scan engine B), a target scan configuration that matches the currently in use scan engine can be determined from the plurality of scan configurations (e.g., scan configuration 2 and scan configuration 4). The plurality of scan configurations may include locally stored scan configurations and may also include cloud stored scan configurations (i.e., cloud scan configurations).

The process of determining a target scan configuration is a process of loading a configuration, and fig. 3 is a schematic diagram illustrating a method for loading a configuration provided in the present application.

After the PDA initiates the load configuration, it is first determined whether the PDA has a local scan configuration stored. When the PDA stores the local scanning configuration, the PDA may load the local scanning configuration, that is, determine the local scanning configuration as the target scanning configuration, thereby rapidly driving the scanning engine to operate and increasing the response speed of scanning.

When the PDA does not save the local scanning configuration, the PDA can determine a target scanning configuration from the cloud scanning configuration and/or the default scanning configuration, wherein when the PDA inquires the cloud scanning configuration, the PDA can load the cloud scanning configuration to acquire the scanning configuration matched with the scanning engine; when the PDA queries the cloud scan configuration, e.g., when the PDA is offline, the PDA may load a default scan configuration to enable the user to complete the scan.

When the PDA acquires the cloud scanning configuration, the cloud scanning configuration corresponding to the plurality of scanning engines can be acquired at one time, and when the scanning configuration is loaded next time, the scanning configuration does not need to be acquired from the cloud, so that the loading speed of the scanning configuration loaded next time can be increased.

After the PDA loads the target scan configuration, the following steps may be performed.

And S230, driving the scanning engine to scan by using the target scanning configuration.

The PDA using the method 200 can automatically determine the type of the scan engine and automatically load the scan configuration according to the type of the scan engine without the user intervening in the scan configuration loading process of the scan engine, so that even a user without professional knowledge can normally use the PDA to scan in different scan scenes. In addition, the PDA applying the method 200 can automatically load scan configurations in the background, and thus different scan configurations can use the same UI without a software vendor developing a UI for each scan engine, thereby reducing software development cost and improving software development efficiency.

In the scanning process of the PDA, the initial scanning result obtained by the scanning engine can be processed according to the preset rule to generate the final scanning result.

For example, the scan engine obtains 1234356 the preliminary scan result, and the user needs to replace ab with 3 in the preliminary scan result, then the PDA can process 1234356 according to the preset rule "replace ab with 3 in the preliminary scan result" to obtain 12ab4ab56 the final scan result, and the user does not need to manually change the preliminary scan result, thereby improving the scan efficiency.

The predetermined rule may be other rules, such as adding a carriage back, adding a space, and the like.

Alternatively, the PDA may also detect whether there is a new scanning configuration after the scanning operation is finished. The method by which the PDA updates the scanning configuration is shown in figure 4.

The PDA may initiate a scan service upon power up and load a scan configuration through the scan service, which may be the process shown in fig. 3.

After the scan configuration loading is complete, the PDA begins operation. The PDA may inquire whether the job is finished, for example, when the screen is off, the PDA may determine that the scanning job is finished; when the screen is lit, the PDA may determine that the scanning operation is not over.

After the scanning operation is determined to be finished, the PDA can inquire whether a notice of new scanning configuration exists or not, and if so, the new scanning configuration can be loaded, so that the scanning configuration does not need to be loaded again in the next scanning operation, and the response speed of the next scanning operation is improved.

The new scanning configuration is, for example, a scanning configuration saved and pushed by a partner in the cloud and/or a scanning configuration set and saved by a user. When there are multiple new scan configurations, or when the new scan configurations do not need to be loaded immediately, the PDA may save the new scan configurations locally, so that the scan configurations may be loaded locally when the scan configurations are loaded next time, which may increase the loading speed of the scan configurations loaded next time.
