Problems solved by technology

Therefore, the above differences bring about the difference in the manufacturing process between the EMMC used in the field of automation control and the EMMC used in the field of consumer electronics. Since the EMMC used in the field of industrial automation control needs to have high temperature resistance, its The production process is more complicated and the production cycle is longer, resulting in higher production costs and relatively low production efficiency

Embodiment 1

[0019] figure 1 The schematic flow sheet of the EMMC high temperature protection method provided for the embodiment of the present invention one, as figure 1 shown, including:

[0020] Step 11, create a virtual joint file system in the internal memory of the terminal device, the joint file system includes a standby file directory and an EMMC file directory, and the EMMC file directory corresponds to the storage path of data in the terminal device EMMC, so The backup file directory corresponds to the storage path of the data in the memory of the terminal device;

[0021] In this embodiment, since most of the terminal devices that tend to generate high temperature during operation are some industrial automation equipment (such as electrical equipment, aerospace equipment, and nuclear power grid equipment, etc.), the terminal equipment in this embodiment is preferably industrial automation equipment. In the prior art, it is necessary to specially configure high-temperature-resi...

Embodiment 2

[0046] In this embodiment, the aufs file system and the tmpfs file directory are taken as examples, and the operation procedures for controlling the aufs file system to the tmpfs file directory and the EMMC file directory are described in detail for different temperature stages generated by the EMMC.

[0047] Such as Figure 2A As shown, when the terminal device is just turned on, the current temperature value of the EMMC is generally low at this time. At this time, the aufs file system can be controlled to store the data generated by the application program in the corresponding tmpfs file directory. memory, and can control the aufs file system to read the data required by the application program from the tmpfs file directory and the EMMC file directory, and at the same time, in order to ensure that the memory corresponding to the tmpfs file directory exists When high temperature has enough storage space to store data, it is necessary to control the tmpfs file directory to tra...

Embodiment 3

[0051] image 3 The structural representation of the EMMC high temperature protection device provided for the embodiment of the present invention three, as image 3 As shown, it specifically includes: a joint file system creation module 31 and a control module 32;

[0052] The joint file system creation module 31 is used to create a virtual joint file system in the memory of the terminal device, the joint file system includes a backup file directory and an EMMC file directory, and the EMMC file directory corresponds to the terminal device EMMC The storage path of the data in the backup file directory corresponds to the storage path of the data in the internal memory of the terminal device;

[0053] The control module 32 is used to control the joint file system to store the data generated by the application program in the memory corresponding to the backup file directory when detecting that the temperature of the EMMC is the first temperature value, and interrupt the The join...

Abstract

The present invention discloses a high temperature protection method and apparatus for an EMMC. The method comprises: creating a virtual joint file system in memory of a terminal device, wherein the joint file system comprises a backup file directory and an embedded memory EMMC file directory, the EMMC file directory is corresponding to a data storage path in the EMMC of the terminal device, and the backup file directory is corresponding to a data storage path in the memory of the terminal device; and when detecting temperature of the EMMC is a first temperature value, controlling the joint file system to store application-generated data into the memory corresponding to the backup file directory, and simultaneously interrupting the joint file system to carry out a data reading or storage operation based on the EMMC file directory, wherein the first temperature value exceeds a preset temperature threshold value. The method and apparatus disclosed by the embodiments of the invention can improve heat resistance of an ordinary EMMC from a software level, thereby improving production efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of information storage, and in particular to a high temperature protection method and device for an embedded memory (Embedded Multi Media Card, EMMC). Background technique [0002] With the rapid development of science and technology, the products in the field of industrial automation control and consumer electronics continue to grow rapidly. At present, EMMC used in products in the field of industrial automation and control (such as electrical equipment, aerospace equipment, and nuclear power grid equipment, etc.) and EMMC used in products in the field of consumer electronics are produced separately. [0003] Since products in the field of industrial automation and control may generate high temperatures due to long-term operation during operation, this requires the EMMC used in the field of industrial automation and control to have high temperature resistance; while products in the fie...
