[0097] The present disclosure provides a method for storing state data. The method is applied to a data storage system. The data storage system includes a central storage device, multiple edge storage devices, and multiple data acquisition devices. The processing flow of the method can be as follows: Figure 5 As shown, the following steps are included:

[0098] 501, the data collection device collects status data.

[0099] The data acquisition device may be a pressure sensor, a temperature sensor, etc., and the acquisition frequency of the data acquisition device may be preset, for example, once per second. The state data includes at least one of pressure, temperature, flow, liquid level, and vibration information.

[0100] 502. The data collection device determines a target edge storage device among multiple bound edge storage devices.

[0101] There are multiple edge storage devices in the data storage system. The data acquisition device can select the edge storage device according to the actual situation. When the amount of status data is large, the number of edge storage devices can be increased. When the amount of status data is small, the number of edge storage devices can be reduced.

[0102] 503, the data acquisition device sends status data to the target edge storage device.

[0103] When the data acquisition device sends the status data to the target edge storage device, it may simultaneously send the device identification of the data acquisition device and the start time of sending the status data to the target edge storage device.

[0104] 504. The target edge storage device stores the status data.

[0105] 505, the target edge storage device sends status data to the central storage device.

[0106] 506. The central storage device stores the status data.

[0107] In a possible implementation, the data collection device may determine a target edge storage device among multiple bound edge storage devices in multiple ways.

[0108] Method 1 for determining the target edge storage device:

[0109] The data acquisition device determines the target edge storage device among the bound multiple edge storage devices based on a round-robin method. For example, the current data acquisition device collects status data once a second, and can send the collected status data to three edge storage devices respectively. The device identifiers of the three edge storage devices are A, B, and C respectively. At this time, the data acquisition device can send the status data collected in the first second to edge storage device A, the status data collected in the second second to edge storage device B, the status data collected in the third second to edge storage device C, the status data collected in the fourth second to edge storage device A, and so on, in this order.

[0110] Method 2 for determining the target edge storage device:

[0111] Based on the pre-established correspondence between the state type and the edge storage device, and the state type of the state data, the corresponding target edge storage device is determined. As shown in Table 1, a correspondence table between the state type and the edge storage device can be pre-established. For example, the state data collected by the pressure sensor can be sent to the edge storage device A, and the state data collected by the temperature sensor can be sent to the edge storage device B.

[0112] Table 1 Correspondence between status types and device identifiers of edge storage devices

[0113] Status Type Device identification of edge storage devices pressure A temperature B flow C Liquid level D Vibration information E

[0114] Method 3 for determining the target edge storage device:

[0115] The plurality of edge storage devices in the data storage system include a management edge storage device, and the processing flow of the third method for determining the target edge storage device can be as follows: Figure 6 As shown, the following steps are included:

[0116] 601. Manage edge storage devices to obtain storage space occupancy information of each edge storage device.

[0117] The management edge storage device can periodically obtain the storage space occupancy information of each edge storage device. For example, the data acquisition device sends a notification to the management storage device to determine the target edge storage device. After receiving the notification, the management storage device can obtain the storage space occupancy information of each edge storage device bound to the data acquisition device. For another example, the management edge storage device obtains the storage space occupancy information of each edge storage device once a minute.

[0118] The storage space occupancy information may include information such as the storage space already used and the unused storage space of each edge storage device.

[0119] 602. For each data acquisition device, the management edge storage device determines a first edge storage device among the multiple edge storage devices bound to the data acquisition device based on the storage space occupancy information of the multiple edge storage devices bound to the data acquisition device and the load balancing mechanism, and sends a notification message carrying the device identifier of the first edge storage device to the data acquisition device.

[0120] The management edge storage device determines the edge storage device with the most unused storage space from the multiple edge storage devices bound to the data acquisition device as the first edge storage device, and then sends a notification message to the data acquisition device, and the notification message can carry the device identification of the first edge storage device. For example, there are three edge storage devices in the data storage system, and the device identifications are A, B, and C, and the unused storage space is 50GB, 45GB, and 20GB, respectively. The management edge storage device can determine the edge storage device with device identification A as the first edge storage device based on the load balancing mechanism, send a notification message to the data acquisition device, and carry the device identification A in the notification message.

[0121] 603. The data collection device records the device identification of the first edge storage device.

[0122] 604 , the data collection device determines the first edge storage device from the bound multiple edge storage devices based on the recorded device identifier of the first edge storage device.

[0123] The data acquisition device uses the first edge storage device as a target edge storage device.

[0124] In a possible implementation, the management edge storage device can establish a correspondence between the device identification of the data acquisition device, the device identification of the edge storage device, and the start time. The correspondence can be used to determine the edge storage device storing data during the data query process. The corresponding processing flow can be as follows: Figure 7 As shown, the following steps are included:

[0125] 701. A data collection device sends a collection time corresponding to status data and a device identifier of the data collection device to a first edge storage device.

[0126] For example, the collection time corresponding to the status data 1 is 8:00, the device identifier of the data collection device is a, and the data collection device can send the above information to the first edge storage device.

[0127] 702. The first edge storage device stores the collection time, the device identifier of the data collection device, and the status data in correspondence.

[0128] The first edge storage device may establish a correspondence table between the collection time, the device identification of the data collection device and the status data, for example, as shown in Table 2.

[0129] Table 2 Correspondence between collection time, device identification of data collection equipment and status data

[0130] Status data Collection time Device identification of data acquisition equipment Status data 1 8:00 a Status data 2 8:01 b …… …… ……

[0131] The first edge storage device establishes the above correspondence table based on the collection time, the device identification and the status data of the data collection device.

[0132] In addition, the above correspondence relationship can be sent to a central storage device.

[0133] 703 , the data collection device records the time of the device identification of the first edge storage device, and determines it as the start time of sending the status data to the first edge storage device.

[0134] 704. The data collection device sends a confirmation message to the management edge storage device.

[0135] The confirmation message carries the start time.

[0136] 705 , the management edge storage device establishes a correspondence between the device identification of the data acquisition device, the device identification of the edge storage device, and the start time based on the confirmation messages received from the data acquisition devices.

[0137] For any corresponding relationship item in the corresponding relationship, including the device identification of the first data acquisition device, the device identification of the first edge storage device and the first start time, the time when the first data acquisition device uses the first edge storage device is the time between the first start time and the second start time, wherein the second start time is the next start time of the first start time among the multiple start times corresponding to the device identification of the first data acquisition device. For example, as shown in Table 3, the management edge storage device can establish a corresponding relationship table of the device identification of the data acquisition device, the device identification of the edge storage device and the start time. It can be seen from Table 3 that the status data collected by the data acquisition device a from 8:00 to 8:05 is stored in the edge storage device A, and the status data collected from 8:05 to 8:10 is stored in the edge storage device B.

[0138] Table 3 Correspondence between the device identification of the data acquisition device, the device identification of the edge storage device and the start time

[0139] Device identification of data acquisition equipment Start time Device identification of edge storage devices a 8:00 A a 8:05 B a 8:10 C b 8:00 A …… …… ……

[0140] Based on the above correspondence table, the management edge storage device can record the edge storage device corresponding to each data acquisition device at any time, so as to facilitate the subsequent processing and analysis of the status data.

[0141] In addition, the management edge storage device may send the corresponding relationship between the device identification of the data acquisition device, the device identification of the edge storage device, and the start time to the central storage device.

[0142] In a possible implementation, the stored status data can be queried, and the corresponding processing flow can be as follows: Figure 8 As shown, the following steps are included:

[0143] 801. A management edge storage device receives a query request sent by a terminal device.

[0144] When there is a query demand, the user can enter the query information on the terminal device, and the terminal device can send a query request to the management edge storage device, where the query request carries the query information, and the query information may include query time information, the device identification of the data acquisition device to be queried, etc. For example, 8:00 and the device identification of the data acquisition device is a, 8:00-8:10 and the device identification of the data acquisition device is b, etc.

[0145] 802 , the management edge storage device determines the device identifier of the edge storage device to be queried based on the corresponding relationship, the query time information, and the device identifier of the data acquisition device to be queried.

[0146] The management edge storage device can determine the edge storage device to be queried that meets the query information based on Table 3 and the query information. For example, the query time information is 8:00, the data collection device is a, and the management edge storage device determines in the correspondence table that the device identifier of the edge storage device to be queried is A.

[0147] 803 , the management edge storage device sends a query request to the edge storage device to be queried.

[0148] 804. The edge storage device to be queried queries the status data corresponding to the query time information and the device identification of the data acquisition device to be queried based on the collection time corresponding to the locally stored status data and the device identification of the data acquisition device.

[0149] The edge storage device to be queried can determine the status data that meets the query information based on the above Table 2. For example, the device identifier of the edge storage device to be queried is A. After receiving the query request, A can determine the status data 1 that meets the query information in the correspondence table.

[0150] 805. The edge storage device to be queried sends the queried status data to the terminal device.

[0151] In addition, when there is a query demand, the user can enter the query information on the terminal device, and the terminal device can send a query request to the management edge storage device or to the central storage device. After sending the query request to the central storage device, the central storage device can query the status data.

[0152] In the disclosed embodiment, a data storage system is used to store status data. The data storage system includes multiple edge storage devices and a central storage device. In this way, the corresponding processing pressure is shared by multiple storage devices, reducing the processing pressure of a single data storage device. A large amount of status data generated in a short time can be processed in time, preventing the status data from not being stored quickly and in time, and preventing the status data from being lost.

[0153] Based on the same technical concept, an embodiment of the present disclosure provides a device for storing state data, which is applied to a data storage system.
