Description
Technical field
The utility model relates to a kind of electricity and communication field, specifically a kind of former car data collecting device mixing combustion system based on bavin oil and gas.
Background technique
Along with country put into effect continuously to vehicular emission administer requirement and restriction, new energy, clean energy resource are rapidly developed in the technical application of automotive fuel.It is one of development trend of China Diesel automotive fuel that diesel/natural gas dual-fuel mixes combustion.This technology on the basis of diesel engine, installs a set of use rock gas additional mix combustion system as the double fuel of combustion material, control automobile by diesel/natural gas mixed combustion control system to realize with rock gas being main fuel, using a small amount of diesel oil as the fuel supply mode ignited.Because this technology is changed little to original diesel engine, repacking cost is low, and in actual motion, diesel oil use amount reduces obviously, and tail gas blowdown declines to a great extent.This technology has obtained examination & approval and the support of government in some areas, enter the Market for refitting of diesel car.
Diesel/natural gas dual-fuel mixes combustion system when normally running, and needs each service data when accurately grasping vehicle operating as oil consumption, the speed of a motor vehicle, rotating speed etc.The current domestic method installing corresponding sensor and the former car sensor of partial sharing in retrofit process additional of usually taking completes collection to vehicle operation data, this method can increase the work difficulty of field technician in actual application, also can cause some uncertain impacts to diesel/natural gas dual-fuel mixed combustion system cloud gray model.On the one hand, for the state's trimotor adopting mechanical control method, although this method exists some problems, but be reasonable solution, and on the other hand, for state four motor adopting electronic control mode, this method has been not just best solution.
Summary of the invention
The utility model provides a kind of former car data collecting device mixing combustion control system based on bavin oil and gas, this device is for ensureing that bavin oil and gas mixes combustion control system and normally effectively runs and provide a set of feasible hardware device, and structure is simple, quick for installation, to overcome the deficiencies in the prior art.
The utility model is achieved in that the former car data collecting device mixing combustion system based on bavin oil and gas, comprise core processor unit, core processor unit is connected with the communication interface for being connected with mixed combustion control system, driver module and the communication acquisition interface for being connected with former car communication system, driver module is connected with display screen.
Owing to have employed technique scheme, compared with prior art, the utility model is by the communication interface by state three or state four motor, read and analyze the data information that communication interface uploads, for double fuel mixes the real-time running data that combustion system provides each former car sensor to gather, ensure that double fuel mixes the normal operation of combustion system.The utility model just can be completed and former car communication interface and mixed connection of firing control system by simple plug, and it normally runs guarantee diesel gas mixed combustion control system for realizing, and carrying out collection to vehicle real-time running data provides hardware foundation.The utility model using process is simple operations, and installs simple, greatly reduces the pressure of field technician's maintenance work, ensures that derv fuel and natural gas double-fuel mixed combustion control system are normally run.The utility model structure is simple, and with low cost, using effect is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the former car data collecting device mixing combustion system based on bavin oil and gas, comprise core processor unit 5, core processor unit 5 is connected with the communication interface 2 for being connected with mixed combustion control system 1, driver module 4 and the communication acquisition interface 6 for being connected with former car communication system 7, driver module 4 is connected with display screen 3.
In the present embodiment, core processor unit 5 can adopt the universal microprocessor (as flush bonding processor, single-chip microcomputer, DSP digital signal processor etc.) of being used widely, microprocessor should have outstanding calculated performance and the excellent system responses ability to event, can adapt to the challenge to low dynamic and static state power demand in reality simultaneously.
Communication module 2 adopts standard universal communication chip (as RS485 chip or CAN chip etc.) and interlock circuit composition, carries out information exchange such as Operational Limits, system to report an error code etc. according to communications protocol and mixed control system 1 of firing.
Driver module 4, display driver chip and interlock circuit composition, according to the control overflow of core processor unit, drive display screen 3, show corresponding information.
Communication acquisition module 6, adopt standard universal communication chip (as CAN chip, K bus chip, LIN bus chip) and interlock circuit composition, interface also adopts automobile-used mark communication interface (as automobile-used ECU standard communication interface, automobile-used OBD interface etc.); Set up fast hardware with former car communication system 7 be connected for realizing the utility model, core processor unit 5 reads the communication data of former car by communication interface 2.
Display screen 3, adopts the TFT display screen of conventional band touch-control on the market at present, under the driving of driver module 4, completes the display to read communication data, and possess simple debugging operations function; Display screen 3 just can complete the connection with driver module 4 by simple plug operation, and outside debug exception operation, display screen 3 is not the equipment that must install.
In the present embodiment, except display screen 3, other module can combine, and installs on the OBD interface of operator cabin or Engine ECU standard communication interface, then is connected to by delay line on the communication interface of mixed combustion Systematical control core board.
For convenience of execute-in-place, above-mentioned each parts, when connecting, can be extended by flexible row's cable as required.In the utility model, each parts those skilled in the art can require select voluntarily or design concrete product or circuit according to its application function.
The Placement of the said equipment is the known approaches of those skilled in the art, just repeats no more herein.
