Description
Technical field:
The utility model relates to a kind of fuel and sprays analogue means, relates in particular to a kind of for constant volume combustion bomb high-speed image and temperature, Simultaneous Pressure acquisition system.
Background technology:
Constant volume combustion bomb can be used near constant volume combustion process modeling effort engine cylinder inner carrier top dead centre, for observing change, respectively tests the impact that initial parameter produces combustion process.The use about constant volume combustion bomb in the past, is all generally to take its spray burning process by high-speed camera, just sees the process of its motion.In this course, ignored the isoparametric consideration of the pressure and temp in constant volume combustion bomb, even if consider this problem, also with spray burning, do not done together synchronous research.Need to know that temperature, these parameters of pressure for in-cylinder combustion are very important beyond doubt.
By above some existing problems, proposing the system of a kind of synchronous acquisition constant volume combustion bomb internal spraying burning High-motion picture of design and internal temperature, pressure parameter just, is necessary, for the research of the spray burning in cylinder provides more concrete help.
Summary of the invention:
Technical problem to be solved in the utility model is, together with the high speed image of motion is collected with corresponding parameter synchronization so that the later stage it is studied accurately; The High-motion picture exactly fuel injector being photographed when constant volume combustion bomb internal spraying burns specifically, with the temperature in constant volume combustion bomb, the synchronous acquisitions such as pressure; See no longer merely image motion, but in conjunction with the parameter in cylinder, observe spray burning situation.
For constant volume combustion bomb high-speed image and temperature, a Simultaneous Pressure acquisition system, comprising:
Gather the high-speed camera 4 of constant volume combustion bomb 6 images; The data collecting card 3 of temperature, pressure in constant volume combustion bomb; The fuel nozzle 7 being connected with constant volume combustion bomb; Control the ECU unit 5 of fuel nozzle; Voltage switch 2, is connected with high-speed camera, data collecting card, ECU unit; Data-carrier store 1, is connected with the output terminal of high-speed camera, the output terminal of data collecting card.
Described data collecting card is data collecting card 80C51, by low level, triggers, and has 4 parallel IO mouths, i.e. P0, and P1, P2, P3, each port has 8 IO mouth lines.
The beneficial effects of the utility model are:
(1) realize the synchro measure collection of spray burning image and the pressure and temp of high-speed motion, be more conducive to the research to in-cylinder combustion;
(2) be on the basis of original constant volume combustion bomb, add outside harvester, simple in structure, be easy to realize.
Accompanying drawing explanation:
Fig. 1 is the utility model device overall schematic; In figure, 1 representative data storer, 2 representative voltage switches, 3 representative data capture cards, 4 represent high-speed camera, and 5 represent ECU unit, and 6 represent constant volume combustion bomb, and 7 represent fuel nozzle.
Fig. 2 is the data collecting card 80C51 adopting in embodiment; Data collecting card 80C51 adopts low level to trigger, and has 4 parallel IO mouths, i.e. P0, P1, P2, P3, each port has 8 IO mouth lines, and P3 mouth also has the second function, for distinctive signal input and output and control signal (genus control bus), VCC represents chip power, connects+5V; VSS represents earth terminal.
Embodiment:
By describing technology contents of the present utility model, architectural feature in detail, being realized object and effect, in conjunction with embodiment and coordinate accompanying drawing to describe in detail.Below in conjunction with accompanying drawing and specific implementation method, to this practicality is novel, be described in further details.
In Fig. 1, in constant volume combustion bomb 6, install upward pressure sensor and temperature sensor additional, the sensor of varying number can be installed as required, so that the different interfaces that obtain wanting and the data of position;
Two class sensors are connected to the image data passway on data collecting card 3, by data collecting card, complete the collection to pressure and temperature;
Voltage switch 2 needs and high-speed camera 4, data collecting card 3, and ECU unit 5 is connected, and wiring is as shown in Figure 1; When using, press lower switch, voltage switch can send the trigger voltage of a 5v, can synchronously trigger high-speed camera, data collecting card and ECU unit, the moving image of the high velocity fog burning that makes to obtain by high-speed camera and pressure, temperature data are synchronous, to keep in this course the frequency of data collecting card and high-speed camera consistent, only in this way just can make the moving image and the data that obtain synchronous.The temperature obtaining, pressure data and High-motion picture finally synchronous recording are stored in the middle of data-carrier store, are convenient to the research in later stage.
The utility model is not limited to embodiment discussed above.Above the description of embodiment is intended in order to describe and illustrate the technical scheme that the utility model relates to.Apparent conversion based on the utility model enlightenment or substitute and also should be considered to fall into protection domain of the present utility model.Above embodiment is used for disclosing best implementation method of the present utility model, so that those of ordinary skill in the art can apply numerous embodiments of the present utility model and multiple alternative reaches the purpose of this utility model.
