It should be understood that the data access request refers to a request of a data access program in a device to be accessed, where the data access request may be a request sent by different data access programs at the same or different time, and the data of the first device refers to stored data of a device without a built-in virtual structure, where the stored data may be data generated by the first device during operation, or may be data transmitted by other devices.
It can be understood that when the data access request is obtained, the data of the first device is obtained through the driver connected with the first device, wherein the driver may be the driver originally connected with the first device or may be the driver connected with the second device, and when the vendor identification information (Voltage Identification, VID) and the identification code information (Port ID, PID) of the first device and the second device are completely consistent, the data of the first device may be accessed through both the driver of the first device and the driver of the second device, wherein the VID and the PID may each uniquely identify different devices.

Further, in order to effectively improve the accuracy of the data written to the second device, step S20 includes: acquiring equipment data fed back by a target cloud server; if the data of the first equipment are inconsistent with the equipment data, respectively counting the number of the data of the first equipment and the number of the equipment data; if the number of the data of the first device is smaller than the number of the data of the device and the data of the first device belongs to the data of the device, correcting the data of the first device according to the data of the device; and writing the corrected data of the first device into the second device through the first driver.
It can be understood that when the data in the second device is changed, the sources of the data are divided into two types, and when the data of the first device at this time is inconsistent with the data stored in the target cloud server database, the data in the first device and the data stored in the target cloud server need to be counted, the number of the data of the first device is smaller than the number of the data in the target cloud server, and the data of the target cloud server completely contains the data of the first device, the data of the first device is corrected and perfected through the data of the target cloud server, and the corrected data is written into the second device.

Further, in order to effectively improve the query efficiency of the virtual device data access record, step S30 includes: based on the multi-service virtual equipment responding to the data access request, obtaining a corresponding access record; the access records are sent to a target cloud server, so that the target cloud server stores the access records and feeds back corresponding storage results; and displaying the successfully stored data in the storage result so as to realize the access of the data based on the virtual equipment.
It can be understood that the access record refers to a record of the multi-service virtual device accessed by the data access application program, the access record includes access time, specific accessed data and the like, in order to reduce the storage space of the multi-service virtual device, when the access record is obtained, the access record is transmitted to the target cloud server, the target cloud server stores the access record to the local database, and the data access application program displays the storage result, so that the problem that when the data in the multi-service virtual device is maliciously changed, the specific access object cannot be traced to, and difficulty is brought to the investigation work of the security department.
Further, in order to effectively improve the data access efficiency, after step S30, the method further includes: carrying out real-time statistics on the successfully stored data to obtain the corresponding data quantity; and if the data quantity is larger than the preset quantity, resetting the access record of the second equipment to receive the data access request at the next moment.

It is understood that when the vendor identification information of the first device is identical to the vendor identification information of the second device and the identification code information of the first device and the identification code information of the second device, the data of the first device is read by the first driver and the data access request, and when either the vendor identification information or the identification code information of the first device and the second device is inconsistent, the data of the first device cannot be acquired by the first driver and the data access request.
In a specific implementation, if the vendor identification information of the first device is identical to the vendor identification information of the second device and the identification code information of the first device is identical to the identification code information of the second device, the data access application program obtains the data of the first device according to the data access request.
It should be understood that, referring to fig. 4, fig. 4 is a schematic view of an access system according to an embodiment of a data access method based on a virtual device of the present invention, and the conversion system includes an execution body of the method, that is, a data access application program, specifically including: the method comprises the steps of first equipment, a driving program, a first application program, second equipment provided with multi-service virtual equipment, the first driving program, the second driving program and a target cloud server, wherein when the first equipment receives a data access request, the data access request is sent to the data access application program, the data access application program reads data of the first equipment through the first driving program, the data of the first equipment is written into the second equipment, the data of the first equipment is configured to the multi-service virtual equipment through the second driving program, and the data in the multi-service virtual equipment can also be sourced from the target cloud server.
