[0066] In the first embodiment of the present invention, a data storage method is applied to data acquisition equipment, such as figure 1 As shown, the method includes the following specific steps:
[0067] Step S101, storing the collected data into a setting memory.
[0068] In this embodiment, the collected data is not specifically limited, and may be collected audio data, collected video data, or collected satellite positioning data.
[0069] For example, step S101 includes: storing the collected video data during driving into a setting memory.
[0070] For another example, step S101 includes: storing the collected video data and real-time satellite positioning data during driving into a setting memory.
[0071] In this embodiment, the memory is not specifically limited, including volatile memory (Volatile Memory), such as random access memory (Random Access Memory, RAM); it may also include non-volatile memory (Non-Volatile Memory) , such as read-only memory (Read-Only ...

[0088] In the third embodiment of the present invention, a data storage method is applied to data acquisition equipment, such as image 3 As shown, the method includes the following specific steps:
[0089] Step S301, storing the collected data into a setting memory.
[0090] Step S302, according to the time stamp of data collection, the collected data is cut into a plurality of time stamp segment data; each time stamp segment data is compressed and encoded according to the hash coding rules, so as to obtain the corresponding time stamp segment data Reference tag sequence.
[0091] The collected data is compressed and encoded by the preset coding rules to obtain the reference label sequence, which effectively reduces the storage capacity of the collected data, so that the data can be transmitted for the data compressed reference label sequence, avoiding the need to modify the collected data The data transmission caused by the transmission is slow and occupies too much transm...

[0095] In the fourth embodiment of the present invention, a data verification method is applied to data verification equipment, such as Figure 4 As shown, the method includes the following specific steps:
[0096] Step S401, when verifying the data stored in the setting memory by the data acquisition device, compress and encode the data stored in the memory according to a preset encoding rule to obtain reference encoded data.
[0097] In this embodiment, the memory is not specifically limited, and includes volatile memory, such as random access memory; it may also include non-volatile memory, such as read-only memory, flash memory, hard disk or solid-state hard disk; Combinations of the above types of memory may be included.
[0098] In this embodiment, the preset encoding rule is the same encoding rule as the reference encoding data generated by the data acquisition device, or an encoding rule matching the reference encoding data generated by the data acquisition device.
