Abstract

The invention relates to an industrial data transmission terminal which comprises a terminal body, an interface arranged on the outer surface of the terminal body and an encryption module storing a secret key, the encryption module is connected with the interface in a pluggable mode, and the terminal body comprises a processor which is arranged in the terminal body and contains the same secret key as the encryption module. The encryption module is installed on the terminal body in an external plugging mode, each external encryption module can independently write a specified secret key through a special configuration tool, and then the secret key is written into the processor of the corresponding terminal body, so that the secret keys contained in the processor and the encryption modules are the same. In this way, a unique encryption key needs to be obtained from the encryption module in the transmission processes such as startup authentication, data acquisition and data control of the single terminal body, and key proofreading is carried out. Therefore, the independent operation function of the encryption module is realized, the operation is simple and convenient, and the software operation safety in the data transmission terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of industrial internet of things, in particular to an industrial data transmission terminal. Background technique [0002] The industrial Internet of Things industry has various data transmission terminals, referred to as DTU. The basic functions of DTU include data collection, data upload and data delivery control. At present, the mainstream DTU data transmission method is transparent transmission, and the security of the transmission process is divided into two categories: one is the DTU with no encryption protection design during the data transmission process; the other is the DTU with the encryption protection function during the data transmission process, but The encryption key is universal, that is, a single key corresponds to multiple DTUs of the same model. At present, the second type of DTU is commonly used in the market, but for this type of DTU, due to its versatility, the software runnin...
