Vehicle-mounted data storage device and storage method

Abstract

The invention provides a vehicle-mounted data storage device. The vehicle-mounted data storage device is characterized by comprising a microcontroller, a vehicle-mounted data interface module, a non-fixed storage medium interface module, a fixed storage medium for storing vehicle-mounted data and an RTC (Real-time Clock) module for providing time information. The microcontroller is connected with vehicle-mounted equipment through the vehicle-mounted data interface module and is used for obtaining the vehicle-mounted data and judging whether vehicle-mounted data is new data or not and storing the data into the fixed storage medium according to pre-set time in forms of a file and a document folder. According to the vehicle-mounted data storage device provided by the invention, the non-fixed storage medium interface module is accessed into the non-fixed storage medium and downloading is carried out. According to the device and method, provided by the invention, large-capacity data storage can be realized, storage veins are clear and rapid exporting of the data can be realized.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a vehicle-mounted data storage device and a data storage method. Background technique [0002] The safety of trains during high-speed operation is an important content of high-speed train research. Various factors such as climate conditions, line conditions, power grid conditions, and electromagnetic environment have an impact on the operation of train electrical equipment, and these factors are often not replicated and simulated during the experiment. Therefore, in addition to the usual train safety recorder (black box), key subsystems of the train such as chargers, axle temperature detection systems, etc. also need to be equipped with similar data tracking and recording devices. The device can record and display the operating status of the equipment in real time, and is used to analyze the impact of various environmental factors on the reliability and safety o...

Problems solved by technology

However, the data storage medium of the previous electrical equipment is an on-board chip, the storage capacity is very limited, and only a small number of events can be recorded.

[0003] When equipment maintenance personnel or technicians view historical event records, the general method is to transmit data between the data communication cable and the personal computer, and write the corresponding human-computer interaction interface on the personal computer side, that is, the personal computer must be carried when viewing the data records , data communication cables, and sometimes communication conversion boards and their drivers are required, which is inconvenient and data transmission is slow
