Embodiment Construction

[0024] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0025] The invention discloses a CAN bus instrument indicator light device. Compared with the existing disadvantage that each indicator light needs to be connected separately, the application utilizes a controller integrated on the control circuit board to connect a group of CAN buses to connect the indicator light Arranged on the control circuit board. The wiring harness connecting each assembly to the existing instrument indicator light is canceled, the number of wiring of the existing instrument indicator light is greatly reduced, and the problems of complex assembly wiring and high failure rate are solved. Moreover, it can solve the problem that the existing vehicle instrument indica...

Abstract

The invention discloses a CAN bus meter indicator lamp device. The device comprises a shell, a control circuit board and N indicator lamps, wherein the N indicator lamps are connected to the control circuit board, and the control circuit board is installed on the bottom of the shell and corresponds to the positions of the N indicator lamps; and the control circuit board includes a controller, thecontroller receives and reads CAN bus information and judges and drives the corresponding indicator lamp to turn on and off. It can be seen that the CAN bus meter indicator lamp device utilizes an integrated controller on the control circuit board to connect a set of CAN buses and the indicator lamps are arranged on the control circuit board. The wiring harness of each assembly connected to the existing meter indicator lamp is eliminated, the wiring number of the existing meter indicator lamp is greatly reduced, and the problem of complicated assembly wiring and high failure rate are solved. In addition, the problem that the meter indicator lamp of an existing vehicle cannot directly perform CAN communication can be solved, and the device can automatically control the indicator lamp to achieve on-off according to the CAN bus information directly.

Description

technical field [0001] The application relates to vehicles, in particular to a CAN bus instrument indicator light device. Background technique [0002] At present, special vehicles, passenger cars, etc. generally use the corridor instrument indicator lights to indicate various signs. [0003] The instrument indicators currently in use are as attached figure 1 shown, with figure 1 It is a variety of integrated instrument indicators. [0004] Further, please see Figure 2-Figure 4 , is a schematic diagram of each orientation of the instrument indicator light. At present, this kind of instrument indicator light is controlled by high and low levels and cannot be connected to the CAN bus. CAN is the abbreviation of Controller Area Network (CAN). CAN belongs to the category of field bus. It is an effective Serial communication network supporting distributed control or real-time control. Therefore, the existing wiring mode of the indicator light cannot realize CAN communicati...
