If the visitor's access rights are not lower than the required access data device information access rights, the required access data are respectively called from the device information database, the required access data are aggregated and the response is loaded; Otherwise, the required access data are respectively called from the device information database, the required access data are aggregated and the required access data exceeding the device information access rights are removed, and the remaining required access data are loaded in response; A segmented loading response unit is used to obtain a loading response data volume of the required access data according to the required access data; Obtain the total access resource allocation and the preset access resource allocation upper limit quantization value corresponding to the visitor access rights; Determine the upper limit quantization value of the moment access resource allocation at the same access moment according to the visitor information at the access moment and the total access resource allocation amount; When the amount of loading response data of the demand access data is not higher than the preset upper limit quantization value of the access resource allocation and the upper limit quantization value of the access resource allocation at the moment, the amount of loading response data of the demand access data is recorded as the amount of segmented loading response data, and the demand access data is directly loaded in response; Otherwise, the smaller quantized value of the preset upper limit quantized value of the access resource allocation and the upper limit quantized value of the access resource allocation at the moment is recorded as the segmented loading response data amount, and the segmented loading response is performed for the required access data; A preload response unit is used to predict the visitor's next required access data and determine the access correlation between the next required access data and the current required access data according to the historical access records; When it is monitored that the access correlation between the device information and the currently required access data is not less than a preset correlation value, the device information is determined to be the next required access data and a preload response is executed; A reload response unit, used to determine the data consistency of the load response data and the preload response data with the required access data, and to perform a data reload response to the inconsistent data; A resource allocation unit, used to determine the visitor's access resource allocation amount according to the loading response, preloading response, segmented loading response and reloading response, and to make a loading response to the actual access data; Wherein, F represents the amount of access resources allocated to the visitor; ti1 represents the time taken by the visitor's i1th required access data to load the response; xi1 represents the number of historical access records of the i1th required access data; yi1 represents the number of historical access records of the i1th device information; xyi1 represents the number of historical access records of the i1th required access data and the i1th device information being accessed simultaneously; Indicates the access relevance between the i1th device information and the i1th required access data When it is not lower than the preset relevant value, output 1, otherwise, output 0; y1i1 represents the data volume of the i1th device information; F1 represents the data volume of the segmented loading response; si1 represents the data consistency ratio of the i1th required access data; x1i1 represents the data volume of the i1th required access data; n1 represents the total amount of required access data.

5. A device information management system based on a two-dimensional code according to claim 4, characterized in that: The access management module also includes: The access test unit is used to perform access test on the visitor's required access data. When the access test efficiency and access test quality meet the access test settings, the access test is determined to be passed, and the required access data is actually loaded in response according to the visitor's access resource allocation.

6. A device information management system based on a two-dimensional code according to claim 1, characterized in that: Alarm management module, including: The alarm management unit is used to set the data verification cycle of the equipment information, periodically verify the equipment information entered in the equipment QR code, generate alarm data and execute the corresponding alarm release strategy when it is detected that the equipment reaches the set replacement period or inspection period; The alarm warning unit is used to set the alarm warning period and issue an early alarm warning when the equipment is about to reach the set replacement period or inspection period.

7. A device information management system based on a two-dimensional code according to claim 1, characterized in that: Material in and out management module, including: The material in-and-out management unit is used to count the consumption of various materials and supplies, automatically generate reports on the inventory and usage of various materials, and manage the in-and-out status of all materials in the warehouse.

8. A device information management method based on a QR code, characterized in that: include: Step 1: Enter the device information in the device QR code and update the device information database; Step 2: Build a hierarchical password management platform. When a visitor accesses the device QR code, the visitor's access rights are enabled, and the visitor's access resource allocation is determined based on the actual access data, and the actual access data is loaded in response; Step 3: Periodically verify the device information in the QR code. When the device reaches the set replacement period and inspection period, generate alarm data and execute the corresponding alarm release strategy; Step 4: Manage the in-and-out data of warehouse materials based on the device QR code.
