Abstract
The utility model relates to a sound alarm module for the CAN bus faults of cars. The utility model is characterized in that the sound alarm module for the CAN bus fault of cars is connected with a main control box for a CAN bus through an LIN bus. The sound alarm module for the CAN bus fault of cars with the structure can visually and concretely report the conditions of a car lamp system, car doors and a hand brake of the car in the form of sound, so that a driver can quickly and accurately master the conditions of the car, and the driving security is greatly improved. Simultaneously, the utility model has the advantages of fault positioning, high accuracy and strong real time performance. The utility model is good for eliminating the fault, and is safer and more convenient in use.
Description
Technical field
The utility model relates to vehicle electric field, and particularly automobile CAN-bus fault alarm field specifically is meant a kind of automobile CAN-bus failure voice alarm module.
Background technology
At present, the automobile CAN-bus technology that China researches and develops voluntarily just has been in development, in the prior art, just it is indicated for the fault of car electrics in CAN bus situations such as (as:) fault, the parking brake of illuminating lamp, signal lamp do not put, car door does not close with signal lamp or sound, chaufeur is only known fault has been taken place on the car, does not know the concrete position of fault.Therefore fault localization and the trouble removal for the CAN bus caused certain difficulty, and it is untimely to report to the police simultaneously, caused certain difficulty for the normal use of automotive electric equipment.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of real time fail location, the automobile CAN-bus failure voice alarm module that fault localization is accurate, trouble removal is easy, safe and convenient to use are provided.
In order to realize above-mentioned purpose, automobile CAN-bus failure voice alarm module of the present utility model has following formation:
This automobile CAN-bus failure voice alarm module, its principal feature are that described automobile CAN-bus failure voice alarm module is connected with CAN bus master system box by the LIN bus.
Described automobile CAN-bus failure voice alarm module comprises a central processor CPU, one end of this central processor CPU is connected with CAN bus master system box by the LIN bus, this central processor CPU also is connected with an alarm voice chip with several button indicator lamps respectively, described alarm voice chip is connected with a warning driving circuit, and this warning driving circuit is connected with an alarm speaker.
Owing to adopted the automobile CAN-bus failure voice alarm module of this utility model, this alarm module can come out the situation of automobile lamp system, car door and parking brake by the concrete report directly perceived of the form of voice, make chaufeur can grasp the situation of automobile fast and accurately, improved the safety of driving greatly, make that simultaneously fault localization is rapid and accuracy rate is high, real-time, be beneficial to clearing of a fault, use safe ready more.
Description of drawings
Fig. 1 is an automobile bus control scheme drawing of the present utility model.
Fig. 2 is an automobile CAN-bus failure voice warning function block diagram of the present utility model.
The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1ly, whole automobile bus uses the technical standard of CAN bus.CAN (Controller Area Network) is called as controller local area network, is commonly referred to as the CAN bus network.This system mainly is made up of three parts: master control box 1, preceding control capsule 2 and back control capsule 3.Wherein be connected by CAN bus 4 between master control box 1, preceding control capsule 2 and the back control capsule 3.Preceding control capsule 2 is connected with right steering lamp 20, right front park lamp 21, country beam 22, passing light 23, fog lamp 24, left front park lamp 25, left steering lamp 26, rain shaving electrical machine 27, washing motor 28, air condition clutch 29, electronic fan 210 and loudspeaker 211, and back control capsule 3 is connected with steering indicating light 30, brake lamp 31, taillight 32, fog tail lamp 33, backing-up lamp 34, back defrosting 35, fuel charger 36 and back windscreen wiper 37.Automobile CAN-bus failure voice alarm module 6 is connected with CAN bus master system box 1 by LIN bus 5.LIN (Local Interconnect Network) is called as Local Interconnect Network's network, is commonly referred to as the LIN bus network.
See also shown in Figure 2 again, this automobile CAN-bus failure voice alarm module 6 comprises central processor CPU 40, one end of this central processor CPU 40 is connected with CAN bus master system box 1 by LIN bus 5, this central processor CPU 40 also is connected with an alarm voice chip 42 with several button indicator lamps 41 respectively, described alarm voice chip 42 is connected with a warning driving circuit 43, and this warning driving circuit 43 is connected with an alarm speaker 44.
In the use of reality, the function of automobile CAN-bus failure voice alarm module 6 is achieved as follows: CAN bus master system box 1 is gathered car light, signal lamp, parking brake, signals such as car door, by LIN bus 5 breakdown signal is passed to CAN bus failure audio alert functional module 6, this CAN bus failure audio alert module 6 is according to alarm content, send instruction to alarm voice chip 42, drive the corresponding concrete alarm voice that this alarm voice chip 42 will record in advance and be sent to alarm speaker 44 by warning driving circuit 43, play back then, thereby fast and accurately fault is reported out by the form of audio alert.
In this specification sheets, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
