Described outside OBD equipment has multiple, can be connected on OBD extended line simultaneously.
The beneficial effects of the utility model: achieve multiple equipment and coexist at an OBD port, OBD equipment is brought more experience functions, the OBD equipment on same vehicle that solves interacts and causes the problem of OBD equipment cisco unity malfunction.
Accompanying drawing explanation
The utility model has accompanying drawing 1 width:
Fig. 1 is Structure Figure of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Solve a device for OBD equipment problem of mutual exclusion, comprising: power management module, OBD interface, outside OBD equipment and checkout equipment, described outside OBD equipment and checkout equipment include: central processing unit and CAN transceiver; Described power management module is connected with OBD interface, and OBD interface is also connected with checkout equipment by OBD extended line, and outside OBD equipment is connected on OBD extended line; Described power management module is powered for this device; Described OBD interface is for being connected with the OBD diagnose connector on car; Described CAN transceiver is for reading the OBD data of diagnose interface; Described central processing unit is used for the OBD data of real-time listening and the reading of process CAN transceiver.Described outside OBD equipment has multiple, can be connected on OBD extended line simultaneously.
The workflow of this device is: the OBD data that the central processing unit real-time listening of checkout equipment and process CAN transceiver read, when CAN transceiver read be outside OBD equipment send data time, the central processing unit prompting of checkout equipment has outside OBD equipment access, and checkout equipment is set to non-operating mode, outside OBD equipment can normally be worked, when removing external diagnostic equipment, checkout equipment is resumed work.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
