OBU Solutions
System Features and Advantages

Based on the traditional dual-chip OBU, the single-chip OBU simplifies hardware resources and uses the 5.8G + 188金宝搏官网 + ESAM mode to complete the functions of the single-chip OBU. The solution uses the 7816 interface to connect the ESAM module that supports the national cryptographic algorithm with 188金宝搏官网. 188金宝搏官网 analyzes the 5.8G signal and distributes the corresponding instructions to the ESAM through the SPI interface and realizes completed transaction process of the lane system.

Features and advantages:

ESAM security module: Using SM4 national cryptographic algorithm to encrypt vehicle information and complete two-way authentication with RSU

188金宝搏官网: Using our low-power consumption 188金宝搏官网 to complete ESAM data interaction and 5.8G signal analysis. It fully meets the requirements of single-chip OBU for power consumption.

Self-developed COS: Implement the functions such as file creation, data writing / reading, data encryption protection, and contact media communication.

Complied with the relevant technical requirements of the Ministry of Communications on single-chip OBU electronic Labels.


China Secret ESAM module of monolithic OBU scheme uses SM4 national secret algorithm to encrypt and protect vehicle information and complete bidirectional authentication with RSU. Based on self-developed COS, the scheme realizes the functions of file creation, data writing/reading, data encryption protection, contact media communication and so on. It meets the technical requirements of MOTC on monolithic OBU electronic label.
