Some taxpayers have full-time accountants use tax control equipment and PC (Personal Computer) invoicing software to complete various tax control business operations such as issuing invoices by themselves; some large enterprises have multiple tax numbers, and one tax control device can only issue invoices with one tax number. Therefore, large enterprises usually hope to centrally manage multiple tax control devices to achieve tax services such as intelligent invoicing to save labor costs; some small and micro enterprise users do not have full-time accountants and lack tax knowledge, and prefer to entrust tax-related businesses such as invoicing to trusteeship or accounting companies.

[0060] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0061] Before describing in detail a management method, apparatus, storage medium, hosting device and system for a tax control device provided by the present disclosure, the management system of the tax control device involved in the present disclosure is first described.

[0062] The management system of the tax control device provided in the present disclosure can host a device and at least one tax control device inserted into the host device. It is worth noting that the tax control device can be connected to the host device through a USB interface. In addition, the tax control device involved in the present disclosure can be a dedicated tax control device, such as a tax control computer. The tax control device can also be a device related to tax invoices, such as a tax control computer, a tax invoice printer, a scanner for authenticating special value-added tax invoices, etc. The present disclosure does not make specific limitations on this.

[0063] Figure 1 FIG. 1 is a schematic diagram of a hosting device according to an exemplary embodiment. Figure 1 As shown, the hosting device may include a power supply 101, an industrial computer 102, and multiple hub circuit boards 103. The power supply 101 is respectively connected to the industrial computer 102 and the multiple hub circuit boards 103, and is used to supply power to the industrial computer 102 and the multiple hub circuit boards 103. The industrial computer 102 includes a memory and a processor, wherein a computer program is stored in the memory, and the processor is used to execute the computer program in the memory to implement the management method of the tax control device provided in the present disclosure. For example, a tax control service program is installed in the industrial computer 102, and the tax control service program can execute the management method of the tax control device provided in the present disclosure. Multiple hub circuit boards 103 are used to provide N USB interfaces, wherein at least a part of the N USB interfaces are used to insert tax control devices, and N is an integer greater than 1.

[0064] It is worth noting that, assuming that there are 4 hub circuit boards 103 and each hub circuit board 103 has 45 USB interfaces, the 4 hub circuit boards 103 can provide 180 USB interfaces. Each USB interface can be used to plug in a USB device, which may include a USB flash drive, a hard disk, a mouse, a keyboard, a tax control device, and the like.

[0065] In one embodiment, the industrial computer 102 may use an Intel Pentium CPU and a Windows 10 operating system, the power supply 101 may use an ATX power supply, and the hub circuit board 103 may implement cascade expansion through a two-stage HUB chip to support the insertion of 45 tax control devices. Optionally, considering the heat dissipation problem of the hosting device, in one embodiment, Figure 1 As shown, the hosting device may further include a plurality of fans 104 for heat dissipation.

[0066] The following is a detailed description of a management method for a tax control device provided by the present disclosure. Figure 2 is a flowchart of a method for managing a tax control device according to an exemplary embodiment. The method is applied to Figure 1The hosting device shown in FIG. 1 can be applied to the industrial computer 102 in the hosting device. Figure 2 As shown, the management method may include the following steps.

[0067] In step 201, the fiscal control device inserted into the hosting device is detected.

[0068] As mentioned above, since the hosting device provides a USB interface, any USB device can be inserted into the hosting device. In order to avoid non-tax control devices being inserted into the hosting device used to host tax control devices, in the present disclosure, it is first necessary to detect whether the USB device inserted into the hosting device is a tax control device.

[0069] In one embodiment, the managed device includes multiple USB interfaces, and the tax control device that detects the USB device inserted into the managed device can obtain whether the USB device inserted into the USB interface is a tax control device through the Windows message mechanism. Specifically, first, when the managed device is in operation, the Windows system notification information of each USB device inserted into the USB interface is obtained through the Windows message mechanism, wherein the Windows system notification information includes first information for representing that the USB device is inserted into or removed from the USB interface, and second information for representing the symbolic link name of the USB device.

[0070] For example, the managed device or the industrial computer in the managed device registers the USB device class with Windows to obtain the windows system notification information of each USB device. After obtaining the windows system notification information of the USB device, the windows system notification information is parsed to obtain first information for characterizing the insertion or removal of the USB device from the USB interface and second information for characterizing the symbolic link name of the USB device. For example, the label 1 can be used to characterize the insertion of the USB device into the USB interface, and the label 0 can be used to characterize the removal of the USB device from the USB interface. In addition, the symbolic link name of the USB device can include the PID (product ID) information and / or VID (vendor ID) information of the USB device.

[0071] Next, based on the above-mentioned first information and second information, determine the tax control device inserted into the trusteeship device.

[0072] For example, first, according to the above first information, the first candidate USB device inserted into the managed device is determined, and then, according to the second information, the first target USB device belonging to the tax control device is determined from the first candidate USB device, and the first target USB device is determined as the tax control device inserted into the managed device. Continuing with the above example, the USB device labeled 1 can be determined as the first candidate USB device, and then the first target USB device belonging to the tax control device is determined according to the PID information and / or VID information of the first candidate USB device. Among them, the PID information and / or VID information of the tax control device has been pre-stored in the managed device. For example, the first candidate USB device whose PID information is consistent with the PID information of the tax control device can be determined as the first target USB device, or the first candidate USB device whose VID information is consistent with the VID information of the tax control device can be determined as the first target USB device, or the first candidate USB device whose PID information and VID information are respectively consistent with the PID information and VID information of the tax control device can be determined as the first target USB device. Finally, the first target USB device is determined as the tax control device inserted into the managed device.

[0073] As another example, first, according to the second information, a second candidate USB device belonging to the tax control device is determined, then a second target USB device inserted into the trustee device is determined from the second candidate USB devices, and finally, the second target USB device is determined as the tax control device inserted into the trustee device. The specific method is as described above and will not be repeated here.

[0074] While determining the tax control device plugged into the trusteeship device in the above manner, the non-tax control device plugged into the USB interface can also be determined. For example, a USB device with a label of 1 but a PID and / or VID that is inconsistent with the PID and VID of the tax control device is recorded as a non-tax control device plugged into the USB interface.

[0075] For each USB interface, if it is detected that the USB device inserted into the USB interface is not a tax control device, a prompt message indicating an insertion error is output, and / or an alarm signal is output to remind the operation and maintenance personnel that a non-tax control device is inserted into the USB interface. The alarm signal may be at least one of an acoustic alarm signal, an optical alarm signal, or an acoustic and optical alarm signal.

[0076] In this way, it is possible to avoid inserting non-tax control devices into managed devices, thereby avoiding the disadvantage of increasing management workload by managing non-tax control devices.

[0077] In step 202, the target physical location of each fiscal control device in the hosting device is obtained.

[0078] It is worth noting that the tax control device mentioned in step 201 refers to the tax control device detected and inserted into the hosting device in step 201. In addition, the target physical location of the tax control device in the hosting device refers to the physical location of the USB interface into which the tax control device is inserted, wherein each USB device in Windows has a fixed physical location.

[0079] In one implementation, first, the symbolic link name of each tax control device is obtained. For example, the symbolic link name of the tax control device can be obtained from the Windows system notification information of the tax control device. Then, for each tax control device, the target device instance of the tax control device is determined according to the symbolic link name of the tax control device, and, according to the target device instance, the correspondence between the preset device instance of the USB device and the physical location is queried to determine the target location corresponding to the target device instance.

[0080] For example, based on the symbolic link name of the tax control device, the correspondence between the preset symbolic link name and the device instance can be queried by calling the Windows Setup API, and the device instance corresponding to the symbolic link name of the tax control device can be obtained. The determined device instance is used as the target device instance of the tax control device. After that, the correspondence between the preset device instance of the USB device and the physical location is queried to determine the target location corresponding to the target device instance.

[0081] The corresponding relationship between the device instance and the physical location of the USB device can be determined in the following manner: for all USB devices, by calling the Windows Setup API, the physical locations of all USB devices plugged into the USB interface and the device instances of the USB devices are enumerated, and the corresponding relationship between the device instance and the physical location of the USB device is established.

[0082] In another embodiment, first, the symbolic link name of each fiscal control device is obtained, and then, for each fiscal control device, the relationship between the preset symbolic link name and the physical location is queried to determine the target physical location corresponding to the symbolic link name of the fiscal control device. In this embodiment, the corresponding relationship between the symbolic link name and the physical location is pre-established.

[0083] Among them, the correspondence between the symbolic link name and the physical location can be established in the following way: first, through the Windows Setup API, the device instance of the tax control device is queried according to the symbolic link name of the tax control device, then, the correspondence between the device instance of the USB device and the physical location is determined in the above way, and then, the device instances obtained in the above two steps are compared to establish the correspondence between the symbolic link name and the physical location of the tax control device corresponding to the same device instance. In this way, the correspondence between the symbolic link name and the physical location of the tax control device can be created.

[0084] It is worth noting that after establishing the correspondence between the symbolic link name and the physical location, the correspondence can be stored in the database. When it is detected again that a new tax control device is inserted into the hosting device, the symbolic link of the newly inserted tax control device and its corresponding physical location are determined in the above manner, and the symbolic link of the newly inserted tax control device and its corresponding physical location are associated and stored in the database. In addition, in addition to storing the correspondence between the symbolic link name and the physical location in the database, the relevant information of the tax control device can also be stored in the database, wherein the relevant information of the tax control device can include but is not limited to: tax number, company name, bank of account opening, historical invoice quantity, remaining invoice quantity, current invoice number code, invoice number. In addition, when it is detected that the tax control device is unplugged from the hosting device, the relevant information of the tax control device, as well as the symbolic link name of the tax control device and its corresponding physical location can also be deleted from the database to reduce the occupation of database storage space.

[0085] In another embodiment, the managed device is in a cold start state. Since the number of tax control devices carried by the managed device is large, if the message mechanism is used for processing, the processing is complicated and messages are easily lost, resulting in some tax control devices being unable to be identified. Therefore, in this case, the tax control device can be identified by searching the registry. First, the industrial computer controls all USB devices to power on, finds the symbolic link names of all USB devices through the registry, and then narrows the scope according to the symbolic link name of the tax control device to find the symbolic link names of all tax control devices. After that, according to the symbolic link name, find the device instance corresponding to each tax control device, and finally call the Windows Setup API to obtain the relationship between the device instance and the physical location, thereby establishing the corresponding relationship between the symbolic link name and the physical location of each tax control device, and writing the corresponding relationship into the database.

[0086] It is worth noting that each tax control device corresponds to a tax number. In another embodiment, the correspondence between the tax number and the physical location can also be established in advance. When the trustee performs tax control-related control on the tax control device, the physical location of the tax control device can be determined according to the tax number included in the tax control business request, and then the corresponding symbolic link name is found according to the physical location, so as to call the Createfile API to open the tax control device for various operations.

[0087] In this way, the target physical location of each fiscal control device in the hosting device can be determined.

[0088] In step 203, the target physical location is output and displayed.

[0089] After determining the target physical location of each tax control device in the managed device, the target physical location of each tax control device can be displayed on a display screen, or the target physical location can be sent to the terminal of the operation and maintenance personnel, so that the operation and maintenance personnel can know the target physical location of each tax control device in the managed device, which facilitates the subsequent timely maintenance of the tax control equipment.

[0090] By adopting the above technical solution, the hosting device can automatically obtain the target physical location of each tax control device in the hosting device, and output and display the target location, so that the operation and maintenance personnel can know the target physical location of each tax control device in the hosting device, so as to facilitate the subsequent timely maintenance of the tax control device. In this way, the hosting device can manage multiple tax control devices conveniently and efficiently.

[0091] Figure 3 FIG. 1 is a flow chart showing another method for managing a tax control device according to an exemplary embodiment. Figure 3 As shown, the management method may include the following steps.

[0092] In step 301 (201), the fiscal control device inserted into the hosting device is detected.

[0093] In step 302, the number of invoices issued by each fiscal control device in a historical time period is obtained.

[0094] The historical time period may be the past 30 days, 60 days, half a year, etc. In addition, the hosting device may count the number of invoices issued in each cycle of each tax control device, for example, a cycle may be 1 day, etc., and then the number of invoices issued in the historical time period may be determined by accumulation.

[0095] In step 303, for each fiscal control device, the power-on strategy of the fiscal control device is controlled according to the number of invoices issued.

[0096] For example, when the number of invoices issued is less than or equal to the first preset number, the tax control device is controlled to be in a normally powered-off state. When a tax control service request for the tax control device is received, the tax control device is controlled to be powered on, that is, the tax control device is controlled to be in a powered-on state. When the number of invoices issued is greater than or equal to the second preset number, the tax control device is controlled to be in a normally powered-on state. And, when the number of invoices issued is greater than the first preset number and less than the second preset number, the tax control device is controlled to be in a powered-on state within a first preset period, and in a powered-off state within a second preset period. The second preset number is greater than the first preset number.

[0097] For example, if the first preset number is 30 and the second preset number is 90, when the number of invoices is less than or equal to 30, it indicates that the enterprise has issued fewer tax invoices for the tax number corresponding to the tax control device, that is, the tax control device is used less frequently. At this time, in order to reduce power consumption, the tax control device can be controlled to be always powered off, and when a tax control service request for the tax control device is received, the tax control device is controlled to be powered on. When the number of invoices is greater than or equal to 90, it indicates that the tax control device is used more frequently. In order to avoid the problem of heavy management workload caused by frequent power-on and power-off control, the tax control device can be controlled to be always powered on, and the tax control service request for the tax control device can be responded to in real time to perform corresponding operations. When the number of invoices is greater than 30 and less than 90, the tax control device can be controlled by a time-sharing power-on strategy, that is, the tax control device is controlled to be powered on during the working hours of the day, such as the period from 10:00 to 22:00, and powered off during non-working hours, such as the period from 22:00 to 10:00.

[0098] By adopting the above technical solution, the power-on strategy of the tax control device is controlled by the number of invoices issued by the tax control device in the historical period, which can reduce power consumption and management workload, and improve the intelligence of tax control device management.

[0099] In actual applications, the hosting device can also communicate with the cloud server. For example, a dedicated thread is created in the tax control service program of the hosting device, and the dedicated thread is used to communicate with the cloud server. In this way, when a tax control device inserted into the hosting device is detected, the relevant information of the detected tax control device can be further obtained and sent to the cloud server. Among them, the relevant information of the tax control device can be obtained from the database. In addition, the relevant information of the tax control device includes but is not limited to: tax number, company name, bank, historical invoice quantity, remaining invoice quantity, current invoice number code, invoice number.

[0100] In addition, when a tax control device is detected to be inserted into the hosting device, the operating status of the tax control device can also be updated to the inserted status.

[0101] In a possible manner, the tax control devices inserted into the hosting device can be periodically detected, and for each cycle, when a new tax control device inserted into the hosting device is detected, the relevant information of the new tax control device is sent to the cloud server. For example, assuming that only tax control devices A and B were detected to be inserted into the hosting device in the previous cycle, and tax control devices A, B, and C were detected to be inserted into the hosting device in the current cycle, then the tax control device C is considered to be a new tax control device inserted into the hosting device detected in the current cycle, that is, only the relevant information of the tax control device C is sent to the cloud server in the current cycle. Since the relevant information of the tax control devices A and B has been sent to the cloud server in the previous cycle, it is not necessary to repeatedly send the relevant information of the tax control devices A and B in the current cycle. In this way, the relevant information of the tax control devices inserted into the hosting device recorded by the cloud server can be updated in real time, and the amount of data sent can be effectively reduced, thereby reducing the occupation of communication resources.

[0102] In actual applications, the tax control device may also be unplugged from the managed device. At this time, the relevant information of the tax control device recorded in the cloud server can also be deleted to reduce the storage space occupied. For example, when it is detected that the tax control device is unplugged from the managed device, an instruction for deleting the relevant information of the tax control device is sent to the cloud server, so that the cloud server deletes the relevant information of the tax control device, so that the cloud server will no longer perform any operations on the deleted tax control device in the future. In addition, when it is detected that the tax control device is unplugged from the managed device, a prompt message indicating that the tax control device has been unplugged can also be output to facilitate the operation and maintenance personnel to understand the operation status of the tax control device and further determine whether the tax control device is unplugged abnormally.

[0103] In addition, the hosting device can also control the tax control device in response to the operation request of the cloud server when communicating with the cloud server. For example, an operation request sent by the cloud server is received, and the operation request can be a tax control business request, such as an invoicing request, or a request to deactivate or refresh the tax control device, etc. Then, the tax control device corresponding to the operation request is controlled to perform the corresponding operation.

[0104] For example, the operation request is an invoicing request, which may include: title, tax number, bank account number, category, amount, date and time, etc. The trustee device may determine the tax control device corresponding to the invoicing request according to the tax number included in the invoicing request, and control the tax control device to perform the invoicing operation.

[0105] Optionally, https+AES double security encryption can be used when the hosting device communicates with the cloud server to ensure communication security.

[0106] Optionally, after the cloud server obtains the relevant information and operating status of the tax control device inserted into the hosting device, it can also display the obtained relevant information and operating status of the tax control device through the terminal APP / Web of the operation and maintenance personnel, and the operation and maintenance personnel can also manage the tax control device in real time through the terminal APP / Web.

[0107] The above technical solution effectively meets the enterprise's hosting needs for multiple tax control devices, and the hardware cost of the tax control device hosting is greatly reduced by hosting through the hosting device provided by the present disclosure. Through the intelligent management of tax control equipment, the personnel investment required for operation and maintenance is greatly reduced, and the operation and maintenance cost of tax control equipment is effectively reduced.

[0108] Based on the same inventive concept, the present disclosure also provides a management device for tax control equipment. Figure 4 FIG. 1 is a block diagram of a management device for a tax control device according to an exemplary embodiment. The management device for a tax control device is applied to a trustee device. Figure 4 As shown, the management device 400 of the tax control device may include:
