Embodiment 1

[0030] figure 1 It is a flowchart of a pre-data acquisition method provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation of obtaining pre-data before the event time node, for example, after the vehicle safety device sends out a vehicle alarm, obtain the pre-alarm Set the data, the method can be performed by the pre-data acquisition device, the device can be implemented by hardware and / or software, and generally can be integrated in electronic equipment, the method specifically includes:

[0031] Step 110, setting a data time point for the full amount of data, and sending the full amount of data to the relay data stream;

[0032] Among them, preset equipment will be installed on the vehicle to collect data during the operation of the vehicle. These data are preset and can include positioning, speed, acceleration, vehicle gear, lamp usage, and obstacles around the vehicle, etc. information, the preset device may be a vehicle safety d...

Embodiment 2

[0047] figure 2 It is a flowchart of a pre-data acquisition method provided by Embodiment 2 of the present invention. This embodiment is further refined on the basis of the above-mentioned technical solution. It may be that the data type of the relay data is judged, including: judging Whether the relay data contains an alarm code field; if it contains the alarm code field, then the relay data is the alarm data; if it does not contain the alarm code field, then the relay data is the Full data. The method specifically includes:

[0048] Step 210, setting a data time point for the full amount of data, and sending the full amount of data to the relay data stream;

[0049] Step 220, if the acquired alarm data is preset alarm data of a preset type, store the preset alarm data in a preset cache;

[0050] Step 230, setting a data time point for the preset alarm data, and sending the alarm data to the relay data stream;

[0051] Step 240, if the accumulated data time point obtaine...

Embodiment 3

[0060] image 3 It is a flow chart of a pre-data acquisition method provided by Embodiment 3 of the present invention. This embodiment is further refined on the basis of the above technical solution. It may be that if the relay data is the full amount of data, in the Searching for the preset alarm data corresponding to the relay data in the preset cache includes: obtaining preset device information from the full amount of data; searching the preset cache for information containing The preset alarm data of the preset device information. The method specifically includes:

[0061] Step 310, setting a data time point for the full amount of data, and sending the full amount of data to the relay data stream;

[0062] Step 320, if the acquired alarm data is preset alarm data of a preset type, store the preset alarm data in a preset cache;

[0063] Step 330, setting a data time point for the preset alarm data, and sending the alarm data to the relay data stream;

[0064] Step 340,...

Abstract

The invention relates to a preposed data acquisition method and device, equipment and a storage medium, and the method comprises the steps: setting a data time point for total data, and transmitting the total data to a relay data stream; if the obtained alarm data is preset alarm data of a preset type, storing the preset alarm data in a preset cache; setting a data time point for preset alarm data, and sending the alarm data to the relay data stream; if an accumulated data time point obtained by accumulating the data time points of the relay data by a preset time threshold is earlier than the current time, judging the data type of the relay data; and if the relay data is the full-amount data and the preset alarm data corresponding to the relay data is searched in the preset cache, storing the full-amount data of which the data time point is within the pre-time range of the corresponding preset alarm data. According to the technical scheme, the preamble time obtaining efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a pre-data acquisition method, device, equipment and storage medium. Background technique [0002] In IoT data flow processing, it is possible to encounter an event that passes through the current point in time, and trace back the flow data of the event time point before this event time node. For example, when the vehicle safety equipment monitors the vehicle safety, when a vehicle alarm event occurs, the relevant data of a period of time before the alarm event can be traced back, so as to restore the situation when the alarm occurred. [0003] The existing data acquisition method usually flows the data of the device into the database, and then obtains the pre-data of the device at the event time node by querying the database. However, this method is inefficient in querying data when the amount of data is large, and cannot obtain pre-data in a timely manner. Co...
