The utility model discloses a control unit, the isolation power module, CAN bus circuit, the bluetooth module that link to each other with the control unit respectively, CAN bus circuit is used for linking to each other with vehicle OBD, wherein, the control unit adopts STM32F042, keeps apart power module and adopts the non - steady voltage power module B2405XT -2WR2 of isolation, and bluetooth module adopts the bluetooth of 4.1 editions. The utility model discloses with low costs, small, can realize in car wireless network from the network deployment, is connected with the distal end server with the help of on -vehicle communication gateway, can realize because the maintenance is compared lightly to the reverse control of vehicle in high in the clouds with the tradition.
Description
Technical field
The utility model belongs to and relates to a kind of vehicle data wireless acquisition system.
Background technology
CAN is used as data in automobile and controls the network that communicates, the electronic control system used in automobile and communication system get more and more, between these systems, googol brings difficulty according to exchange capacity to communication analysis, need a kind of equipment to extract vehicle bus data, by the parsing of backstage to bus data, carry out data monitoring, fault diagnosis, the renewal of parameter calibration and ECU firmware.
Current vehicle data wireless acquisition method is by CAN communication interface access bus, accesses computer, coordinate desktop application software at demand pairs according to parsing by the OTG mode of USB.Data acquisition is difficult, and professional equipment price is high, and volume is large, function singleness, on-the-spot chaotic, does not support third-party platform, does not support interconnecting of plurality of devices.
Utility model content
The purpose of this utility model is to provide a kind of vehicle data wireless acquisition system, solves the problem interconnected that current acquisition system does not support plurality of devices.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of vehicle data wireless acquisition system, comprises control module, the insulating power supply module be connected with control module respectively, CAN circuit, bluetooth module; Described CAN circuit is used for being connected with vehicle OBD; Wherein, control module adopts STM32F042, and insulating power supply module adopts isolation brute supply module B2405XT-2WR2, and bluetooth module adopts the bluetooth of 4.1 versions.
The utility model in actual use, pass through bluetooth communication, can realize carrying out exchanges data with many equipment, the data collected can be transferred to computer, mobile phone, or other hand-held set, backstage can be sent data to fast like this, be resolved by backstage centering data, easy to operate.
The utility model compared with prior art, has the following advantages and beneficial effect:
The utility model cost is low, and volume is little, can realize the MANET of wireless network in car, is connected with far-end server by vehicle-carrying communication gateway, can realize the vehicle multi channel based on high in the clouds, safeguards light compared with tradition.
Accompanying drawing explanation
Fig. 1 is system chart of the present utility model.
Fig. 2 is the circuit theory diagrams of insulating power supply module in the utility model.
Fig. 3 is the circuit theory diagrams of CAN circuit in the utility model.
Fig. 4 is the circuit theory diagrams of bluetooth module in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, a kind of vehicle data wireless acquisition system, comprises control module, the insulating power supply module be connected with control module respectively, CAN circuit, bluetooth module; Described CAN circuit is used for being connected with vehicle OBD;
Wherein, control module adopts STM32F042, and it is integrated with 32 performance single-chip microcomputers of the communication interfaces such as USART and CAN.
Owing to often can be subject to the interference such as electrostatic, surge in the application of reality, these interference also can cause system works unstable or cannot work at all, generally need adopt quarantine measures, by input, export between without any electrically on connection.As shown in Figure 2, insulating power supply module of the present utility model adopts isolation brute supply module B2405XT-2WR2.Input power is provided by system, and out-put supply supply analog front circuit, as exported Voltage stabilizing module analog chip (AMS1117).In addition, insulating power supply module of the present utility model can isolate 1500V voltage, and its input voltage 9 ~ 30V, and output ripple is less than 30mv.
As shown in Figure 3, this circuit diagram is CAN circuit, and wherein, MMBZ27VCLT1, provides the electrostatic defending of 16kv.R1/R4 can play the effect of protective current, also can play the effect of resistance.The small capacitances of PESD1CAN is suitable for the system of message transmission rate up to 1Mbit/sec very much.This circuit can be protected and tell and the impact of the transceiver in fault-tolerant CAN net from EMI and ESD.
As shown in Figure 4, bluetooth module of the present utility model adopts the bluetooth of 4.1 versions, and it is dual-mode chip, can realize the data analysis MANET in LAN (Local Area Network).Multiple equipment can be connected, so just user's equipment at one's side all can be coupled together, form a network interconnected.
What deserves to be explained is, the utility model uses blue-tooth technology, realizes the wireless collection of automobile bus data, Data Analysis, offline storage, the aerial upgrade of firmware and the Data-Link support node of vehicle multi channel.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical matters; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
