Handheld terminal, system and battery information processing method thereof

Abstract

Provided are a terminal, a system and a battery information processing method therefor. The terminal comprises a communication module, an identity authentication module, a storage module and a main control module. In addition, the terminal can also comprise a man-machine interaction module which controls the modules and the connection and communication among the modules through the main control module. The system comprises the terminal and a management server. The processing method comprises: conducting identity authentication on an external battery; reading battery information about the battery after passing the authentication, and decrypting the battery information; and conducting asset registration on the decrypted battery information. The terminal, the system and the battery information processing method therefor of the present invention have the advantages of high security, high efficiency, high reliability, convenient and quick operation, etc.

Description

technical field [0001] The invention relates to the fields of wireless transmission, mobile handheld terminal and data encryption, in particular to a handheld terminal, a system and a battery information processing method of the terminal. Background technique [0002] At present, the asset management of electric vehicle batteries mainly exists in the bus or taxi system. Basically, passive radio frequency tags are pasted on the surface of the battery box. Direct replacement, and then bring the old battery back to the original company; while in the warehouse management, directly read the label content on the battery for warehouse registration, which belongs to the company's internal asset management. [0003] When electric vehicles will be popularized on a large scale in the future, they will be extended to many different operating companies or individuals from individual companies such as existing public transport and rental companies. For users of electric vehicles, especia...

Problems solved by technology

[0010] 2. Management information transmission delay and low efficiency during car rescue

[0011] When an electric vehicle has a problem in the field, for example, and the battery needs to be replaced, the operator replaces the battery management system. After the replacement, the information cannot be updated to the main city management system immediately, which may cause blank asset information in the main system, and the whereabouts of materials are unknown. Or it does not match the actual situation, which is not conducive to the subsequent circulation management of batteries

At the same time, rescuers perform text registration at the scene, and they need to enter it into the system uniformly after returning. The time interval in the middle is uncertain, resulting in delayed information in the system, low efficiency, and increased repetitive paperwork for personnel.

[0012] 3. The electric vehicle battery warehouse is inconvenient to manage and has low reliability

The amount of information posted is large, prone to human input errors, and low reliability

[0014] 4. The asset information data volume is small, the encryption is low, and it is inconvenient to carry

Passive RFID is usually a simple RFID such as a barcode, which is read-only but not writable. It adopts plaintext without encryption or low encryption, and the amount of information is small, and the security of encrypted information is low; active RFID can be read and written, and the reading head device is usually larger. , inconvenient to carry

Not suitable for field rescue
