The storage module 104 is a memory, which is a component for storing programs and data, and is divided into a main memory and a secondary memory according to its purpose. The main memory is also called an internal memory (abbreviated as "memory"), such as DRAM, SRAM, FRAM, etc., and is used for temporarily storing operation data in the CPU and data exchanged with the external memory; the auxiliary memory is also called an external memory (external memory for short), such as a hard disk, a usb disk, an optical disk, etc., and refers to a memory except for a computer memory and a CPU cache, which can still store data after power failure.
An internal Memory DRAM (Dynamic Random Access Memory) is the most common internal Memory of a system, and uses a capacitor to store data. Since the conventional capacitor of DRAM uses silicon oxide with a small dielectric constant as an insulator, it is not easy to attract electrons and holes, and the electrons and holes must be continuously compensated to realize data storage, so it is called as DRAM. The DRAM can only store data for a short time, and the data stored in the DRAM is lost as long as the power of the computer is turned off. Compared with DRAM, the internal Memory FRAM (ferroelectric Random Access Memory) uses a ferroelectric material with a large dielectric constant (such as PZT) instead of silicon oxide, and electrons and holes are not lost and have non-volatility.

The processing speed of the internal memory is faster than that of the external memory, but data can be lost after power failure, and long-term storage of the data is not easy to realize. When the data is calculated, if the CPU directly reads from the external memory, the time is too long, so that the internal memory is adopted as an intermediate bridge, the data in the external memory is copied into the internal memory, the CPU can directly read the data from the internal memory, and the data reading time is greatly shortened. In the embodiment of the present invention, the storage module 104 employs two memories of FRAM and NAND Flash to realize data storage.
Specifically, the configuration information storage unit uses FRAM as an internal memory, and uses the ferroelectric effect of a ferroelectric crystal to realize data storage, so as to store the configuration information required by the control module 101, including an IP address of a vehicle-mounted platform, a VIN code of a vehicle, an acquisition interval, and the like. The data acquisition and storage unit adopts NAND Flash as an external storage, the data storage is realized by adopting a nonlinear macro unit mode in the data acquisition and storage unit and is used for storing the acquired data, including pre-stored face images, acceleration values, engine rotating speed, vehicle speed and the like, and when network signal difference occurs and the acquired data cannot be reported to the vehicle-mounted platform in real time, the NAND Flash storage can locally store data for 7 to 14 days at least.
