Abstract
The utility model relates to a load box communication mould card. Among the prior art, a communication mode is only supported to a load box. Current load box only is equipped with CAN modulus of conversion card and can not satisfies RS232 serial port communication. The utility model discloses a mo kanei increases RS232 modulus of conversion card in this communication to and increasing a change over switch between CAN module and RS232 conversion module, a load box just can be supported to carry out the emulation debugging with a plurality of host computer softwares by 2 kinds of communications protocol, is applicable to different customer demands.
Description
Technical field
The utility model relates to a kind of load box communication mould card in automotive test, particularly relates to a kind of load box communication mould card supporting multiple kinds.
Background technology
Working load case is needed strictly to test air bag before automobile dispatches from the factory.In prior art, a load box only supports the single-mode of a kind of CAN communication (ControllerAreaNetwork: controller local area network).For the load box of in-circuit emulation, communication modulus of conversion card must be used, to meet the communication with host computer simulation software.
Find in background technology, to there is following problem by analysis:
Different communications protocol can be used due to some project and carry out artificial debugging, in therefore current load box design, CAN modulus of conversion card is only housed and can not meet RS232 serial communication.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of load box communication mould card.By increasing RS232 modular converter at this communication Mo Kanei, and between CAN module and RS232 modular converter, increase a change-over switch, a load box just can support 2 kinds of communications protocol, carries out artificial debugging, be applicable to different customer demands with multiple upper computer software.
The scheme that the utility model solves the problems of the technologies described above is:
A kind of load box communication mould card, comprises RS232 modular converter and change-over switch.RS232 modular converter is arranged in load box, and change-over switch is arranged between PC and load box.Select when test to be connected with the main control software on PC by CAN communication agreement or by RS232 communications protocol.
The utility model solves the problem that load box of the prior art can only adopt a kind of communications protocol to be connected with PC.Further, owing to the addition of change-over switch, controlling with PC communication by change-over switch is adopt RS232 or CAN protocol.A load box can support 2 kinds of communications protocol, carries out artificial debugging, be applicable to different customer demands with multiple upper computer software.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
In figure: load box (1), ACU (2), change-over switch (3), PC (4), CAN module (5), RS232 modular converter (6), communication conversion chip (7), power supply chip (8).
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model is a kind of load box communication mould card.Comprise RS232 modular converter 6 and change-over switch 3.Communication conversion chip 7 and power supply chip 8 is integrated with in RS232 modular converter 6.
In the utility model, CAN module 5 and RS232 modular converter 6 are fixedly mounted in load box 1.Load box 1 is directly connected by the ACU2 (AirbagControlUnits, safety air sac controller) of wire and automobile.
RS232 modular converter 6 comprises communication conversion chip 7 and power supply chip 8, and transition of communications chip 7 is converted to the information of RS232 form the information of CAN form; Power supply chip 8 is used for powering to RS232 modular converter 6 and change-over switch 3.
CAN module 5 and RS232 modular converter 6 are all connected to the output port of change-over switch 3; The input port of change-over switch 3 is connected on the output port of PC 4 by wire.
When test, select adopt CAN module 5 or adopt RS232 modular converter 6 and load box communication by switching beginning 3.Load box is control ACU2 directly.
In the utility model, communication conversion chip 7 adopts the CAN format conversion of the maturation of Freescale company to be the chip of RS232 form; Power supply chip 8 adopts the power supply chip of XNP company; Change-over switch 3 is also matured product of the prior art, does not all need to do particular design to them in the utility model, therefore repeats no more.
Should be understood that this embodiment is only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the utility model appended claims limited range equally after the content of having read the utility model instruction.
