The present embodiment is described and illustrated below by way of preferred embodiments.
Fig. 4 is a flowchart of another data storage method of the present embodiment. As shown in fig. 4, in this data storage method, an SD card is employed as a storage unit of the target data storage device 410. The first device 408 is a monitoring camera device and is placed outdoors without loading an SD card, the target data storage device 410 is placed indoors with an SD card, and the target data storage device 410 may be a separate storage device connected to the first router 406, or other first devices may be used as the target data storage device. In general, the data of the first device 408 is not stored, and the master device 102 sends the first device stored data to the target data storage device 410 for storage after receiving the alert message.
When the first router 406 and the second router 412 are connected to the cloud server 404, the cloud server 404 records SD memory card information of all the first devices 408 and the second devices 414 in the access network, and data such as memory card usage. The master control device 102 may be a cloud computing platform, and the master control device 102 determines that the first device 408 does not load an SD card according to the acquired SD memory card information, the target data storage device 410 has the SD card, and the second device 414 is a remote connection device of the target data storage device 410, and does not load the SD card; the first router 406 and all devices connected thereto, and the second router 412 and all devices connected thereto, access the cloud server 404 and are connected to the same control terminal 402. The control terminal 402 loads an application program for controlling the above-described devices.
In the above connection scenario, the cloud server 404 bridges the first device 408 and the target data storage device 410 to generate a connection channel. The connection channel may be implemented in a manner that the first device 408 stores the data receiving port IP of the target data storage device 410, and the target data storage device 410 stores the data sending port IP of the first device 408. If the first device 408 has first device stored data generated, the data is sent to the target data storage device 410.
When the target data storage device 410 is another first device, the target data storage device 410 receives the stored data and the data summary corresponding to the alarm information and stores the stored data and the data summary locally, and meanwhile, the target data storage device 410 reports the data summary to the cloud server 404, and the cloud server 404 stores the data summary. When the target data storage device 410 writes data to the SD card, a write-from-head/tail storage method may be employed, and when the target data storage device 410 stores the stored data, the cloud server 404 records the write-to-SD card method.
If the first device 408 generates an alarm event and generates alarm information, the first device storage data corresponding to the alarm information is sent to the target data storage device 410 for storage. The target data storage device 410 stores the first device stored data and the first device data digest and reports the first device data digest to the cloud server 404 for storage.
When the first router 406 accesses other devices, such as a sweeping robot, the sweeping robot transmits data such as an indoor map file of the target data storage device 410, and the target data storage device 410 also receives and stores the indoor map file and a map abstract corresponding to the indoor map file. While the target data storage device 410 uploads the map summary to the cloud server 404 for storage.
In the above data storage method, if different devices generate different device storage data, the storage is performed according to different storage strategies, for example, the first device storage data and the first device data digest are stored on the SD card from front to back, and the second device storage data and the second device data digest are stored from front to back.
Fig. 5 is a flowchart of still another data storage method of the present embodiment. As shown in fig. 5, in the case where the control terminal 402 is simultaneously connected to the second device 414, if the second device 414 does not carry an SD card and does not purchase cloud storage service, after the second device is online to the cloud server 404, the cloud server 404 builds a connection channel for the second device 414 and the target data storage device 410; that is, the second device 414 maintains the data receiving port IP of the target data storage device 410, and the target data storage device 410 maintains the data transmitting port IP of the second device 414. The second device 414 remains alive with the target data storage device 410. When the second device 414 sends data to the target data storage device 410, the data can be directly transmitted without being forwarded by the cloud server 404, and meanwhile, the second device 414 and the target data storage device 410 keep alive to the cloud server 404. Meanwhile, the first device 408 and the target data storage device 410 remain alive at a fixed time or keep alive to the cloud server 404 at the same time; a timed keep-alive is maintained between the robot and the target data storage device 410.
Fig. 6 is a flowchart of still another data storage method of the present embodiment. As shown in fig. 6, if the subsequent first device 408 and/or second device 414 performs storage space expansion, for example, in a case that an SD card is inserted into the first device 408 and/or second device 414, in a case that an expansion space is added to an independent target data storage device 410, or in a case that a purchase of a cloud storage value added service is added, a storage space expansion message is reported to the cloud server 404 with the data storage device with the added storage space, and the cloud server 404 sends a message for releasing the original data transmission channel relationship to the corresponding data storage device.
Taking the first device 408 as an example, the first device storage data stored in the target data storage device 410 is not immediately cleared after the expansion of the storage space is performed as described above. Cloud server 404 analyzes data time span T of first device storage data maintained on target data storage device 410. The data time span of the next first device storage data is Ta, and the space occupied by the historical first device storage data stored on the target data storage device 410 is Tb, ta+tb=t. If the data time span of the next first device storage data has reached T, i.e., tb=0, then the space occupied by the historical first device storage data stored in the target data storage device 410 has been fully freed. The historical first device data summary corresponding to the historical first device stored data stored on the cloud server 404 is also synchronously released.
It should be understood that, although the steps in the flowcharts of fig. 2-6 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows; the data interaction between the devices shown in the above figures is bi-directional, and although the figures are unidirectional arrows, it is not meant that the data is only transmitted unidirectionally as in the figures in the actual data processing.
