The invention discloses a passive light-splitting RS-485 optical fiber bus local side system. The system is characterized in that the two ends of the system are connected with an RS-485 bus control terminal and a passive RS-485 optical network terminal of an industry optical fiber bus for passive light splitting respectively. The system comprises a power module, a main control panel, a plurality of plane waveguide optical dividers and a plurality of light ports which are connected. The main control panel comprises an RS-232 center control interface, an RS-485 center control interface, two RS-485 cascade interfaces, a plurality of photoelectric conversion modules and a bus arbitration processor. The RS-232 interface and the two RS-485 cascade interfaces are connected with the bus arbitration processor and the RS-485 bus control terminal. One ends of the multiple photovoltaic conversion modules are connected with the bus arbitration processor, and the other ends of the multiple photovoltaic conversion modules are connected with one ends of the plane waveguide optical dividers. The other ends of the plane waveguide optical dividers are connected with the light ports.

The invention relates to an accessing method in a first accessing subnet of a wireless communication network. The accessing method includes the following steps: establishing initial connection between the subnet and a user device; receiving a second service request from the user device; forwarding the second service request to a core network; receiving second service downlink data from the core network or second service uplink data from a second access subnet; sending the second service downlink data to the second access subnet, or sending the second service uplink data to the core network; and the wireless communication access technology adopted for the first access subnet and the wireless communication access technology adopted for the second access subnet are different. Through the accessing method, the limitation on the data rate of the user device by different wireless accessing technologies can be eliminated, the user device can enjoy various types of service simultaneously, and the network architecture can be simplified.

The invention discloses a method for realizing an electronic control domain system of a whole vehicle. The method includes: the signal processing module receives at least one sensor signal for motor control, and inputs the at least one sensor signal into an algorithm module; the algorithm module determines the current state of the vehicle according to the at least one sensor signal, And estimate the vehicle state at the next moment, and obtain a control instruction according to the current state of the vehicle and the vehicle state at the next moment, wherein the control instruction carries a motor identification; the instruction output module converts the control instruction according to the motor identification Send it to the driver corresponding to the motor identification so that the driver drives the motor. Through the technical solution of the present invention, the network architecture of the vehicle controller can be simplified, the number of controllers on the vehicle can be greatly reduced and the overall vehicle development cycle.
