Embodiment Construction

[0025] In order to make the purpose, content and advantages of the present invention clearer, below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.

[0026] The invention provides an intelligent jumper, including a power management circuit, a CAN signal circuit, a single-chip microcomputer and a relay control circuit; the power management circuit provides a stable power input signal for the single-chip microcomputer and the relay, and the CAN signal circuit is mainly used for sending and receiving CAN data. The signal of the adapter is sent to the single-chip microcomputer through the CAN signal circuit; after the single-chip microcomputer receives the CAN signal of the CAN1 road, it controls the control terminal of the corresponding relay through logic processing, and the controlled relay is turned off or turned on, thereby controlling the pin corresponding to the CAN2 road signal of the adapter and the correspond...

Abstract

The invention discloses an intelligent jumper which comprises a power supply management circuit, a CAN signal circuit, a single-chip microcomputer, a female end, a male end and a plurality of relay control circuits. The power supply management circuit provides stable power supply input signals for the single-chip microcomputer and relays. The control ends of the relay control circuits are connected with the control port of the single-chip microcomputer and used for controlling the off state and on state of the relays. An adapter packages information for expecting the formation of a channel between a male end pin and a female end pin through a CAN message. The CAN signal circuit is used for sending data of the CAN message of the adapter to the single-chip microcomputer. The single-chip microcomputer controls the control end of the corresponding relay after receiving a CAN signal so that the relay can be turned off or on and the connection between the female end pin and the male end pincan be achieved. The channel between the CAN/K signal of the input port of the intelligent jumper and any pin of the output port can be obtained, and the interaction requirement of different CAN network interfaces of a vehicle OBD port and external information is met.

Description

technical field [0001] The invention belongs to the field of vehicle electric control, and in particular relates to an intelligent wire jumper. Background technique [0002] With the increasing number of vehicle electronic control systems, the CAN network architecture of the vehicle is also becoming more and more complex. There are more and more CAN and K interfaces reserved for the OBD port of the vehicle, and the point definitions of the OBD port CAN\K roads of various OEMs are inconsistent, and some models even have point definitions for all pins of the OBD port. [0003] At present, the commonly used CAN\K adapter design only has 2 CAN lines and 1 K line. When the OBD port has multiple (more than 3) CAN\K channels, the adapter with 2 CAN\1 K lines cannot meet the data sending and receiving requirements. , and the CAN\K waypoint definition of the OBD port is inconsistent with that of the adapter. The solution that adopts at present is to adopt the mode of manual wiring,...
