Description

A kind of device based on OBD interface collection vehicle performance data

Technical field

The invention belongs to running state of the vehicle data collector, be specifically related to a kind of device based on OBD interface collection vehicle performance data.

Background technology

OBD(On Board Diagnostics, i.e. OBD) interface become vehicle standard configuration.During vehicle maintenance, detection computer data interface can be connected with vehicle OBD interface, vehicle internal performance data can be detected computer collection, and according to gathered data analysis, thus make diagnosis.And vehicle is in people's go off daily process, due to Bu Jin maintenance depot or 4S shop, even if vehicle breaks down, and vehicle carries out the function of Real-time Collection to its performance data without self, in a lot of situation, car owner often can not Timeliness coverage, be unfavorable for the timely maintaining of vehicle like this, be also unfavorable for traffic safety.

Summary of the invention

The object of the invention is the deficiency existed for prior art, a kind of device based on OBD interface collection vehicle performance data is provided, can Real-time Collection vehicle performance data by this device, and the behaviour in service of vehicle is controlled according to vehicle performance data cases, be beneficial to vehicle safety trip.

Based on the device of OBD interface collection vehicle performance data, comprise and be arranged on the first wireless terminal on vehicle OBD interface and be arranged on the second wireless terminal that vehicle interior sight line can't see, described first wireless terminal comprises the first primary processor, the first radio receiving transmitting module be connected with the first primary processor, described second wireless terminal comprises the second primary processor, the second radio receiving transmitting module be connected with the second primary processor respectively, storer and executive circuit, described executive circuit is connected with in-vehicle device, the duty of in-vehicle device is controlled according to the instruction of described second primary processor.

Described in-vehicle device comprise in loudspeaker, GPS module, mobile module, light, engine oil way switch one or more.

Beneficial effect of the present invention:

The present invention adopts collection vehicle data to separate with other interlock circuits and processes, first wireless terminal of a collection vehicle performance data is installed on the one hand on vehicle OBD interface, on the other hand the second wireless terminal is arranged on the cover that vehicle interior sight line be can't see, first, the vehicle performance data that first wireless terminal is collected by wireless receiving and dispatching communication mode by the second wireless terminal pass to the second wireless terminal, primary processor in second wireless terminal contrasts according to the vehicle performance data gathered and the normal data being stored in storer, once note abnormalities, control the relevant device on executive circuit operation vehicle, or warning or oil-break etc.Like this, the first wireless terminal be arranged on OBD interface is small and exquisite, exposed without wire in visual line of sight in car, better appearance, meanwhile, during vehicle maintenance computer, pull up appearance also very convenient without connecting the first wireless terminal of wire, whole system also can the work of normal table.

Technical scheme of the present invention is further illustrated below in conjunction with accompanying drawing.

Accompanying drawing explanation

Fig. 1 is the system architecture schematic diagram of the embodiment of the present invention.

Fig. 2 to Fig. 7 is the schematic diagram that the executive circuit in the present invention connects from different vehicle arrangements respectively.

Embodiment

As shown in Figure 1, based on the device of OBD interface collection vehicle performance data, comprise the first wireless terminal 2 of being arranged on vehicle OBD interface 1 and be arranged on the second wireless terminal 3 that vehicle interior sight line can't see, described first wireless terminal 2 comprises the first primary processor 201, the first radio receiving transmitting module 202 be connected with the first primary processor 201, described second wireless terminal 3 comprises the second primary processor 302, the second radio receiving transmitting module 301 be connected with the second primary processor 302 respectively, storer 303 and executive circuit 304, described executive circuit 304 is connected with in-vehicle device 4, the duty of in-vehicle device 4 is controlled according to the instruction of described second primary processor 302, described in-vehicle device 4 comprises loudspeaker 401, GPS module 402, light 403, engine oil way switch 404, one or more in mobile module 405.Described first radio receiving transmitting module 202 and the second radio receiving transmitting module 301 all can adopt bluetooth module, WIFI module or other wireless transmitter.

As shown in Figure 2, the executive circuit 304 of the second wireless terminal is connected with the loudspeaker 401 in in-vehicle device 4, and the primary processor of the second wireless terminal 3 can control the work of loudspeaker 401 by executive circuit 304.During specific works, if the second wireless terminal 3 collects vehicle trouble code, under the commander of primary processor 302, the dependent failure voice messaging of storer 303 internal memory is given loudspeaker 401 and is play, reach the object of reminding host vehicle to need on-call maintenance, be conducive to safety.

As shown in Figure 3, the executive circuit 304 of the second wireless terminal is connected with the GPS module 402 in in-vehicle device 4.During specific works, in vehicle go off daily process, due to the existing GPS module of this device, OBD interface collection vehicle performance data can be passed through again, like this, comparative analysis together with the driving trace record gathered data and corresponding GPS module, can find the actual location of breaking down, offer help to vehicle trouble analysis.

As shown in Figure 4, the executive circuit 304 of the second wireless terminal is connected with the light 403 in in-vehicle device 4, and can control the open and close of light 403.During specific works, in vehicle go off daily process, various fault may be there is, if there is dependent failure and reflect in the information from the collection of OBD interface, first wireless end meeting at end 2 of the present invention identifies automatically, and informs that the primary processor 302 of the second wireless terminal 3, second wireless terminal 3 will send instruction by wireless receiving and dispatching mode, light 403 is opened bright, reminds host vehicle to need repairing.
