Revised National Standard Co-drafted by Anche Officially Released!

Recently, the national standard GB/T33191-2025 Technical conditions for computer control and interactive communication of motor vehicle safety inspection equipment, which Anche participated in the revision, has been officially released. It will fully replace GB/T33191-2016 and will be implemented from March 1, 2026.

The revision of the standard reflects the technological iteration and development of the motor vehicle inspection industry. This revision fully incorporates the industry’s technological development trends and provides a technical basis for improving the level of motor vehicle inspection technology.

I. Standard Revision Overview

1.Transmission interface & communication method

The revised standard specifies communication interface methods that conform to international standards, such as serial port, network, USB, and Bluetooth, and defines the technical requirements for each interface.

2.Data frame format

The defined data field adopts the JSON data format, which specifies the data and its type, data unit, data validity bits and other specific formats.

3.Communication commands and transmission

The command categories have been changed, and commands for setting session keys and parsing signature error response commands have been added.

4.Communication process

According to GB 38900-2020, the communication process for wheel alignment tester has been removed, and communication processes for automatic measurement devices for vehicle dimensions, curb weight tester/weighbridges, and equipment for testing the operational safety performance of new energy vehicles have been added.

5. Communication time constraints

Time-related parameters during the communication process are specified to ensure the timeliness and effectiveness of communication.

II. Significance of the Revision

1. Improve technical standardization

Focusing on scientific rigor, relevance, operability and coordination, the standardization and technical level of computer control and communication technologies for motor vehicle safety testing instruments and equipment have been improved.

2.Ensure the safety of the inspection system

The regulations regarding data encryption and authentication have been expanded to prevent unauthorized access or data tampering, thereby improving the security of the entire inspection system.

3.Promote the integration and utilization of resources

The regulations on software compatibility have been strengthened, and the basic principles for mutual recognition and support of testing software between different brands and models have been clarified, promoting the effective integration and utilization of resources within the industry.

As a leading enterprise in China's motor vehicle inspection industry, Anche participated in the standard revision, leveraging its profound technological accumulation and rich industry experience, and made a positive contribution to the rigor and completeness of the standard. In the future, Anche will continue to focus on the research and development of testing equipment and the upgrading of testing technologies, providing the industry with more advanced products and higher-quality services, and promoting the healthy development of the motor vehicle inspection industry.
