Introduction
In-depth interpretation of GB/T33191-2016 standard
1. Background and significance of the standard
GB/T33191-2016 "Computer Control and Communication Technology Conditions for Motor Vehicle Safety Technology Testing Equipment" was issued in 2016 to standardize the computer control system and communication protocol of motor vehicle safety technology testing equipment. This standard was proposed and managed by the National Motor Vehicle Operation Safety Technology Testing Equipment Standardization Technical Committee and is applicable to motor vehicle safety technology inspection institutions.
2. Comparison of standard frameworks
| Dimension | GB/T33191-2016 | Comparison standard | Difference analysis |
|---|---|---|---|
| Scope of application | Applicable to motor vehicle safety technology testing instruments and equipment | Only applicable to some testing equipment | Expanded scope of application, compatible with more equipment types |
| Transmission interface | Support RS-232-C, RS-485, Ethernet and other interfaces | Only supports a single interface type | Increased multi-interface compatibility |
| Communication protocol | TCP/IP and full-duplex asynchronous serial communication are adopted | Traditional serial communication is adopted | Communication efficiency and stability are improved |
3. Interpretation of the main contents of the standard
Transmission interface specification
GB/T33191-2016 specifies a variety of transmission interface types, including RS-232-C, RS-485, Ethernet, etc. These interfaces support full-duplex asynchronous serial communication mode, and the data frame format is unified to ensure efficient communication between devices.
Communication process
The standard clarifies the communication process between the control system and the detection instrument equipment, including instruction classification (basic instructions and extended instructions), state management (cooling, preheating, standby, etc.) and exception handling mechanism. For example, the zeroing communication process is shown in Figure 2.
Data frame format
The data frame format consists of the start field, address field, frame length field, command field, data field and check field. The functions and constraints of each part are described in detail in Table 2 to ensure the accuracy and reliability of data transmission.
4. Implementation suggestions
Case study: Practical experience of a certain testing agency
When a certain motor vehicle testing agency implemented the GB/T33191-2016 standard, it first modified the interface compatibility of existing equipment to ensure support for multiple transmission protocols. Secondly, it optimized the communication process and reduced the command response time. Finally, through regular calibration and maintenance, the stability and accuracy of the system were improved.
Implementation step suggestions
- Equipment upgrade: Ensure that the testing equipment supports the transmission interface and communication protocol specified in the standard.
- Process optimization: Redesign the internal communication process according to the standard requirements to reduce delays.
- Training: Provide special training on standard content and operation procedures for technical personnel.
- Verification: Verify the operability and effectiveness of the standard through actual test cases.
