T/ITS 0082-2016 Vehicle-mounted terminal and body power CAN gateway bus transmission technical requirements
Basic Information
Scope
Scope: This standard specifies the architecture for data communication between urban public buses' on-board intelligent terminals and gateways, as well as the interface specifications that must be adhered to. This standard applies to situations where urban public buses' on-board intelligent terminals communicate and control with gateways via the CAN bus. Main technical content: This standard stipulates the general technical specifications of the bus between the on-board terminal and the vehicle power CAN meter/gateway device, including the physical layer, data link layer, and application layer. The main content is as follows: 1. Physical layer: scope of application, standardization, general requirements of the physical layer (physical medium, differential voltage, bus evaluation, terminal resistance), functional description (connection method, wiring inspection), etc. 2. Data link layer: parameter group, message, identifier, priority, node, arbitration, etc. 3. Application layer: address allocation, network topology structure, application layer requirements, etc.
