Micro-rectangular j29a interface intelligent power supply protection three-proof industrial solid-state hard drive

Abstract

The invention discloses a micro-rectangular J29A interface intelligent power supply protection three-proofing industrial solid state drive, which comprises a shell and a circuit board, wherein the shell comprises an aluminum alloy upper cover and an aluminum alloy lower cover; AB glue is added between the shell and the circuit board; the aluminum alloy lower cover is provided with a mounting cavity; the circuit board is mounted in the mounting cavity; the circuit board is provided with a micro-rectangular J29A stranded wire type interface, a power-off protection chip, a central processing unit, a crystal oscillator, a temperature sensing chip, a filtering circuit, a power supply chip, a flash memory module and a built-in intelligent power supply module; according to the micro-rectangular J29A interface intelligent power supply protection three-proofing industrial solid state drive in the invention, the stranded wire type elastic pin is adopted, so that the contact reliability is high,and hot plugging is supported; normally, when a memory disk is replaced or taken down, the user needs to close the system; however, the hard disk can be directly taken out by using the hot plugging technology, and the system can still run normally and uninterruptedly, so that the usability and the application to specific removal occasions are improved.

Description

technical field [0001] The invention discloses a micro-rectangular J29A interface intelligent power protection three-proof industrial solid-state hard disk. Background technique [0002] Solid State Drives (Solid State Drives) are hard disks made of solid-state electronic storage chip arrays, consisting of a control unit and a storage unit (FLASH chip, DRAM chip). According to relevant statistics, shipments increased by 25.8% to 102.78 million in 2015, and the trend of gradually replacing traditional mechanical hard disks has become obvious. However, ordinary solid-state hard disks have many defects, such as The interface is not firmly contacted and easy to shake, does not support hot swapping, data is easily lost during abnormal power failure, and has no three-proof (waterproof, dustproof, shockproof) functions. Application requirements in locomotive, industrial and other fields, and the current solid-state drive interface types are SATA interface, SAS interface, MSATA int...

AI Technical Summary

Problems solved by technology

[0002] Solid State Drives (Solid State Drives) are hard drives made of solid-state electronic storage chip arrays, consisting of control units and storage units (FLASH chips, DRAM chips), which have fast reading and writing, light weight, and energy consumption that traditional mechanical hard drives do not have Low profile and small size, so it is popularized rapidly. According to relevant statistics, shipments in 2015 increased by 25.8% to 102.78 million pieces, and the trend of gradually replacing traditional mechanical hard drives is obvious. However, ordinary solid-state drives have many defects, such as The interface contact is not firm and easy to shake, does not support hot plugging, abnormal power failure data is easy to lose, there is no three-proof (waterproof, dustproof, shockproof) function, the normal use environment of consumer grade is between 0°C and 70°C, which cannot be used in military, The application requirements of locomotives, industries and other fields, and the current interface types of solid-state hard drives adopt SATA interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface. These interfaces are all drawer-type connections. The connection strength is small, it is easy to shake, and cannot withstand large mechanical vibrations
