Embodiment 1
[0057] see figure 2 , in a specific embodiment, the step S10 specifically includes:
[0058] S11, transfer the video device into the memory database;
[0059] S12, according to the region to which the user belongs, select the video device registered in the region to which the user belongs from the memory database;
[0060] S13. From the video devices registered in the area to which the user belongs, filter out the video devices according to the usage frequency in descending order, and send the video devices to the client to generate a device list.
[0061] In this embodiment, the video device is transferred into the memory database Radis, and after the user logs in to the management account through the client, the server checks the weight value of the video device, filters out 20 video devices with the largest weight value, and sends it to the client, the client The terminal establishes a device list, and the user can operate the loaded video device at this time.
Embodiment 2
[0063] see image 3 , in a specific embodiment, the step S20 specifically includes:
[0064] S21. According to the position of the node selected by the user on the map and the display scale of the map, look up the adjacency table of the node to find out the video device whose distance is within the preset range, and send it to the client, where the position of the node represents the video the location of the device;
[0065] S22, record the frequency that the user uses the video device, dynamically calculate the weight value of the video device in the device list, and save the updated weight value to the database;
[0066] S23 , set the weight value of the video device to which the user mark is added as 1.
[0067] In this embodiment, the client finds the adjacency table of the node according to the location of the camera on the map and the display scale of the map, finds out the video devices with similar distances, finds 10 video devices with the closest distance, and sen...
Embodiment 3
[0069] In a specific embodiment, the method for quickly acquiring a large amount of device information with multiple strategies further includes updating the adjacency table of the node when the video device increases or decreases.
[0070] Further, the method for quickly acquiring a large amount of device information with multiple strategies also includes:
[0071] When it is detected that the user mark of the video device is cancelled, the weight value of the video device is calculated according to the frequency of use, and the weight value is updated and stored in the database.
[0072] In this embodiment, when the video device increases or decreases, the adjacency list of the node is dynamically updated, the device weight in the list is dynamically updated, and the weight value is updated and saved to the database, so that the video device with a high weight value is preferentially loaded, and the low weight value is loaded first. The video device is sent to the client in ...
