System for collecting and managing device data

Abstract

A data collection and management system for a device includes: collecting all messages measured by at least one sensor via at least one bus bus, adding a heartbeat frame and at least one identification code of the sensor to each message to form a frame or packet for output; receiving each frame or packet message via at least one device cloud through a signal converter or a communication interface, synchronizing the time according to the heartbeat frame of each frame or packet, adding a corresponding timestamp to each frame or packet, storing each frame or packet with timestamps in a time series database (TSDB), and allowing only writing to the aforementioned path in the time series database, disallowing modification or deletion; and a client accessing the device cloud via an application programming interface (API), enabling the device cloud to provide the client with necessary message packets or provide the necessary message packets to an analysis module (AI) for analysis, and outputting an analysis result.

Claims

1. A data collection and management system for a device, comprising: The system utilizes at least one bus to collect all messages measured by at least one sensor, adding a heartbeat frame and at least one identification code of the sensor to each message to form a frame or packet for output. At least one device cloud receives each frame or packet message through a signal converter or communication interface, calibrates the time according to the heartbeat frame of each frame or packet, adds a corresponding timestamp, and stores it in a time series database. The time series database only allows writing to the aforementioned path, disallowing modification or deletion. A client accesses the device cloud through an application programming interface (API), and the device cloud provides the client with a message packet or provides the message packet to an analysis module for analysis, outputting an analysis result. The bus uses the authoritative clock connected to the gateway as a reference clock source, ensuring that the timestamps assigned to each frame or packet by the device cloud are consistent with the reference clock source time connected to the gateway.

2. The data collection and management system of the device as described in claim 1 further filters, processes, and cleans each frame or packet in the time series database according to the set conditions, and stores it in a structured database.

3. The data collection and management system of the device as described in claim 2, wherein the device cloud encapsulates the necessary information of the structured database to the analysis module for analysis.

4. The data collection and management system of the device as described in claim 1, wherein the bus is extended based on the protocol layer of the controller area network to include the heartbeat frame.

5. The data collection and management system of the device as described in claim 1, wherein the signal converter transmits each frame or packet to the device cloud in USB specification format.

6. A data collection and management system for the device as described in Request 1, wherein when the application interface (API) accesses the device cloud, it only allows one-way provision of client message packets by the device cloud.

7. The data collection and management system of the device as described in claim 1 contains multiple device clouds, each of which is used to receive frames or packets sent from the same bus bus; or each of which is used to receive frames or packets sent from different bus buses.

8. The data collection and management system of the device as described in Request 1, wherein when the analysis module accesses each device cloud through the application interface, it must provide the correct key password, and each device cloud provides the corresponding message packet according to the provided key password and the required scope.

9. The data collection and management system of the device as described in claim 1, wherein after the device receives the analysis results from the analysis module, it converts the signal into a signal conforming to the bus bus specification through the signal converter, and the signal is received by the bus bus and transmitted to each corresponding device.

10. A data collection and management system for the device as claimed in claim 1, wherein the analysis result is displayed at least in a 2D coordinate graph, wherein the horizontal axis of the 2D coordinate graph represents the time indicated by each of the timestamps of one of the sensors during a period, and the vertical axis represents the message or calculated data of the aforementioned sensor corresponding to each of the timestamps during the period.
