Example 1
Referring to fig. 1, fig. 1 is a flow chart of an implementation method for a UHF printer according to an embodiment of the invention. The method described in fig. 1 may be, but is not limited to, an embodiment of the present invention. As shown in fig. 1, the implementation method for a UHF printer may include the following operations:
101. storing the print task issued by the service system to an offline print system with an association relation with the service system, wherein the offline print system is configured in the UHF printer and is used for controlling the work of the UHF printer according to the stored print task.
The mode that the offline printing system is configured in the UHF printer is specifically implemented as follows: the off-line printing system comprises a plurality of UHF readers/writers. First, a database having a plurality of types of UHF reader/writer SDK information is configured in the offline printing system. SDK information in the database is generally provided by a manufacturer of the UHF reader/writer, and includes device information (hardware identifier, model, IP address/bluetooth name, baud rate, etc.), tag information (TID, EPC, read/write time, password, etc.), GPIO information (IO identifier, high level/low level, etc.) and the like of the UHF reader/writer of the corresponding model, and program interfaces for behavior control of the respective UHF readers/writers, which illustratively include: connecting a reader/writer, turning on/off the reader/writer, reading an RFID tag/tags, writing data to a specific RFID tag, and the like. If the SDK information of the subsequently accessed UHF reader is not in the database, the database can be subjected to custom expansion and update, so that the application range is wider, and the SDK information provided by the embodiment is not limited to be stored in a common database, but can be stored in a mode of forming a file and the like. Thereafter, an abstract data interface is constructed. Because the functions and the docking modes of the SDK information provided by the manufacturers of the UHF readers are different, an abstract interface is defined to unify the functions and the docking modes of the SDK information of all the UHF readers, so that an upper computer/service system can conveniently communicate and call by using a cross-platform/cross-language communication interface (RPC/Http/shared file/Bluetooth and the like), and the abstract data interface is specifically realized to unify calling modes by unifying the substantially same characteristics of the readers. Illustratively, the reader-writer A has a function set { open reader-writer, close reader-writer }, its disclosure method corresponding to SDK is { OpenReader () }; the reader-writer B has a function set { open reader-writer, close reader-writer }, and the method for disclosing the corresponding SDK is { EnableReader () }; obviously, the function sets of the A, B two readers are identical, but names/methods are different because of different naming manners of SDKs of different manufacturers. When the same functions of the A, B two types of readers are abstracted through the abstracted data interface, the function sets are collectively named as { OpenReader () }, closeReader () }, so that the calling mode is unified. Illustratively, the SDK information of the UHF reader A is provided in a programming language C++, and is communicated with an upper computer/service system in a serial/USB mode; the SDK information of the UHF reader-writer B is provided in a programming language C# and is communicated with an upper computer/service system in a wired network port mode, and after the two UHF readers of A, B are respectively connected, the upper computer/service system can respectively communicate and control with A, B through a designated programming language (such as Java) and a designated data interface (such as Bluetooth) by the control system. Before the UHF reader-writer is connected, the UHF reader-writer to be accessed is registered through an abstract data interface, and registration information is generated through a manual input mode or an automatic identification mode. The connected UHF reader-writer needs to find the SDK information corresponding to the UHF reader-writer to perform related control operation. Therefore, the type of the accessed reader/writer needs to be identified to find the corresponding SDK in the SDK library. The registration information and the SDK information of the corresponding UHF reader-writer have an association relation and have a unique identification function. The registration information contains basic device information such as device ID of the UHF reader, for example, UID (unique identity) is obtained by means of automatic identification or manual marking for the accessed reader a and reader B to realize registration, and the device is explicitly represented as different devices in the system. Therefore, when in use, the calling party can call the corresponding SDK by the invention only by providing the UID corresponding to the A, B reader-writer. Thus, different UHF readers/writers can be distinguished. When the UHF reader-writer is connected, acquiring registration information of the connected UHF reader-writer, and acquiring SDK information adapted to the connected UHF reader-writer according to the association relation between the acquired registration information and the SDK information. The SDK information comprises a device ID and an SDK storage path, and is specifically realized as follows: firstly, reading the equipment ID of an accessed UHF reader-writer, acquiring an SDK storage path of an associated SDK according to the equipment ID, and connecting to a corresponding SDK in a database according to the acquired SDK storage path, wherein the SDK information also comprises default configuration items matched with each SDK. After the device ID of the accessed UHF reader is read, the default configuration item of the SDK associated with the device ID is obtained according to the device ID, the device is connected to the corresponding SDK according to the obtained SDK storage path, and the accessed UHF reader is driven to work by the default configuration item. The default item can be configured in a self-defined manner according to different service scenes and requirements, so that the mode of connecting the reader-writer, starting the reader-writer and starting to read the RFID tag can be realized, the mode can be realized to at least comprise configuration information for connecting the reader-writer, starting the reader-writer and starting to read the RFID tag, in other embodiments, the mode can also comprise configuration information such as antenna power setting, baud rate setting, IP address setting and the like, the UHF reader-writer can work after being accessed, the SDK can be directly called regardless of any type of UHF reader-writer, only the SDK information is stored in a database, the operation is performed according to the corresponding default configuration item, the function of accessing the diversified UHF reader-writer is realized, and the UHF reader-writer is compatible. Therefore, a database with SDK information of the UHF reader-writer can be built, a referenceable object can be provided before different UHF reader-writers are accessed, and the corresponding UHF reader-writer does not need to be known and learned according to the specification. Thus, the off-line printing system can directly establish connection with the UHF printer through the UHF reader-writer. Further, the off-line printing system may be implemented as a micro-host installed on a UHF printer, and illustratively includes raspberry pie, UP, etc., with a built-in Linux or Windows system having a plurality of different types of data interfaces (e.g., USB, wired network, bluetooth, WIFI, GPIO, etc.). The micro-host provided with the off-line printing system is directly connected with the UHF printer network cable, so that control signals and printing task data can be transmitted.
In order to solve the problem that the UHF printer cannot function normally due to network failure between a service system connected with the UHF printer and the UHF printer in the prior art. An offline printing system with an association relation with the service system is set, and the offline printing system is directly connected with a printer through a UHF reader-writer of the offline printing system. The business system comprises a computer, a mobile phone and other network interruption connected with the UHF printer, and when the network connection is normal, the printing task is issued to the offline printing system for storage, and the establishment of the association relationship is realized by the network connection mode. The mode of issuing the print job can transmit the print job to the offline printing system through a network transmission mode.
102. When the business system and the offline printing system are in a network connection fault state, the offline printing system controls the UHF printer to work according to the currently stored printing task.
When the UHF printer works, network connection with a service system suddenly fails, and the printer stops working in the prior art, so that the working efficiency is greatly influenced. At this time, the offline printing system and the UHF printer are still in a connection state, and data transmission can be performed, so that the print tasks stored in the offline printing system in a lasting mode can be transmitted to the UHF printer, and the UHF printer can still work normally, thereby realizing offline printing.
As an embodiment, the method further comprises: when the UHF printer is restarted, the work of the UHF printer is controlled according to the print task stored by the offline printing system when the UHF printer is closed last time. When the UHF printer is suddenly powered off in use or a service system terminal connected with the UHF printer is suddenly powered off, since the print tasks of all the UHF printers are stored on the micro host computer in a lasting way through the offline printing system, the print task data cannot be lost due to power off. After the UHF printer is powered on again and is started up, the off-line printing system automatically resumes the printing task before power off and continuously controls the UHF printer to continuously execute the printing task. The problem of low working efficiency caused by UHF printers which also need to be artificially transmitted through a service system is avoided.
As an implementation manner, there may be multiple service systems having association with the offline printing system, and different network terminals (such as computer programs and mobile phone APP) of the multiple service systems are connected with the offline printing system at the same time, and when the offline printing system stores a print job, the offline printing system generates a print sequence according to the receiving order of the print job issued by the multiple service systems; and then calling a printing function interface of the UHF printer, and controlling the UHF printer to sequentially execute the printing tasks according to the printing task sequence of the printing sequence. Therefore, UHF printing service can be called at the same time, printing tasks of different network terminals can be sequentially printed according to the first-in first-out order, and the printing tasks are not mutually interfered.
According to the method disclosed by the embodiment, the offline printing function can be realized through the offline printing system, and the problem that the UHF printer cannot print normally when the service system and the UHF printer have network faults in the prior art is solved. Moreover, by configuring the offline printing system and one or more business systems in a management relationship, the UHF printing service can be invoked at the same time, the offline printing system can realize a printing queue, and the printing tasks of different business systems can print sequentially according to the sequence of the printing sequences of first-in first-out, so that the printing tasks are not mutually interfered. Through the storage function of the offline printing system, when the service system terminal or the UHF printer is suddenly powered off, data cannot be lost due to power failure because all the printing tasks are stored through the offline printing system. After the power-on is restored, the off-line printing system automatically restores the state before power-off and continues to execute the printing task.

And the power-off recovery module 4 is used for controlling the work of the UHF printer through the calling module according to the print task stored when the UHF printer is closed last time when the UHF printer is recovered to be started.

generating a printing sequence according to the order of the printing tasks issued by the one or more stored business systems;
and calling a printing function interface of the UHF printer, and controlling the UHF printer to execute a printing task according to the printing sequence.
When the UHF printer works, network connection with a service system suddenly fails, and the printer stops working in the prior art, so that the working efficiency is greatly influenced. At this time, the offline printing system and the UHF printer are still in a connection state, and data transmission can be performed through the offline working module 3, so that the print tasks stored in the offline printing system in a lasting manner can be transmitted to the UHF printer, and the UHF printer can still work normally, thereby realizing offline printing.
When the UHF printer is suddenly powered off in use or a service system terminal connected with the UHF printer is suddenly powered off, since the print tasks of all the UHF printers are stored on the micro host computer in a lasting way through the offline printing system, the print task data cannot be lost due to power off. After the UHF printer is powered on again and is started up, the power-off restoration module 4 automatically restores the print job before power off and continuously controls the UHF printer to continuously execute the print job. The problem of low working efficiency caused by UHF printers which also need to be artificially transmitted through a service system is avoided.
As a preferred embodiment, there may be multiple service systems having an association relationship with the offline printing system, and different network terminals (such as computer programs and mobile phone APP) of the multiple service systems are connected with the offline printing system at the same time, where the offline printing system generates a print sequence according to a receiving order of the print tasks issued by the multiple service systems when storing the print tasks; and then calling a printing function interface of the UHF printer, and controlling the UHF printer to sequentially execute the printing tasks according to the printing task sequence of the printing sequence.
