Agriculture and forestry tractors and machinery Serial control and communication data network Part 2. Physical layer1 ScopeGB/T 35381 provides for agriculture and forestry tractors and suspension, semi-suspension, traction or self-propelled equipment, serial control and communication data network, Its purpose is to enable data transfer between sensors, actuators, control elements and information storage and display units of a suspended or semi-tractor Standardization of methods and formats, and open system interconnection reference model support (OSI) for electronic control systems for agricultural and forestry equipment. GB/T 35381 This section defines and describes the speed of 250kbit/s four core twisted pair unshielded cable physical layer.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document.

General standards for data communications (Tractorsandmachineryforagricultureandforestry-Serialcontrolandcommunicationsatanet- work-Part 1.Generalstandardformobiledatacommunication)3 Terms and definitionsTerms and definitions as defined in ISO 11783-1 apply to this document.4 General rules4.1 network physical layer The network physical layer enables the electrical connection between several electronic control units (ECUs) and network bus segments. Connected electronic control list The total number of elements is limited by the electrical load on the bus segment. The electrical parameters specified in this section, electronic control on each bus segment The total number of ECUs should be 30. 4.2 Physical media This section defines the physical media of a four-core, twisted-pair cable. Two of the wires, named CAN_H and CAN_L, are made by communication Signal driven. The corresponding ECU pin names are CAN_H and CAN_L, respectively. The third and fourth wires, named TBC-PWR and TBC-RTN to power terminal bias circuits (TBCs) on the bus segment. 4.3 differential voltage The voltages of CAN_H and CAN_L relative to ECU_GND (ground) are indicated by VCAN_H and VCAN_L. The difference between VCAN_H and VCAN_L ...... |
