Background technology
At present, in motor road test, the automobile test engineers often will be used the test data acquisition analysis system of being made up of with transducer data acquisition front, notebook computer, vehicle speedometer, speed probe, measurement; In the test macro of such complicacy; The used operating voltage of different instruments is also different, under the situation of direct current supply, and the operating voltages that number is adopted front end; Generally be between 15-28V; The normal working voltage of notebook computer is about 20V, and speed probe, measurement are generally used the 12V working power with transducer, the using electricity system of such complicacy; Depend merely on 12V storage battery or the power supply of 24V storage battery on the automobile; Certainly do not reach requirement, especially when the automobile of only equipping the 12V storage battery (like car, minicar etc.) is gone up use, how to solve number and adopt the key that can the powerup issue of front end, notebook computer have just become test accomplish smoothly.
Under a lot of situation, testing crew can only become the 220V alternating current to adopt analyzer and notebook computer power supply to number the 12V dc inverter on the automobile by using the bigger inverter of volume, but the electric energy of inverter consumption automobile storage battery is very big; Inconvenience is carried very in use, on automobile, use 220V alternating current, measuring-signal receive easily alternating current 50Hz interference; Owing to there is not the ground wire protection on the automobile; The 220V alternating current also constitutes certain threat to the safety of testing crew, and simultaneously, a part of in addition measuring instrument also will use the 12V DC power supply; During test; Wire harness such as various power lines, sensor signal lines are mingled in together, are very easy to go wrong, and reason easy-to-search not.The experimental enviroment of this multivoltage coexistence, also very difficult authenticity and the validity that guarantees acquired signal also influences the operating efficiency of testing greatly.Therefore, to motor road test, the unified electrical problem that how to solve data acquisition system is puzzlement automobile test engineer's a technical barrier always.
Summary of the invention
The purpose of the utility model is to adapt to the motor road test environment, solves that the automobile test data acquisition system is unified powerup issue and the automobile test developed is counted the extraction system power supply changeover device.
The 12V direct voltage of the automobile storage battery of the utility model is connected on two groups of DC-DC voltage transitions chips, and the maximum output voltage of conversion chip is 24～26V; Power access end of one group of banana plug provides the input of 12VDC through this terminal realization 12VDC output or to transducer.
The electrical problem of the disposable solution Vehicular test data acquisition system all appts instrument of the utility model ability, very easy to use.Automobile mounted experiment with measuring through is for many years used, and proves easy to use, the dependable performance of this instrument, and this instrument can also be given instrument or notebook computer charging as charger.

Fig. 1 is the utility model circuit theory diagrams.
Embodiment
The 12V direct voltage of the automobile storage battery of the utility model is connected on two groups of DC-DC voltage transitions chips, and the maximum output voltage of conversion chip is 24～26V; Power access end of one group of banana plug provides the input of 12VDC through this terminal realization 12VDC output or to transducer.
The utility model adopts the encapsulation of all-plastic shell; Forward and backward press mold panel, kernel adopt 2 groups of DC-DC voltage transitions chips, through inserting the 12V direct voltage of automobile storage battery; Through ovennodulation and rectification; Reach and boost and export the galvanic purpose of different high-voltage values, the maximum output voltage of each conversion chip is 24～26V, and peak power output is 120W.
This invention instrument volume is little, in light weight, safe and reliable
Main performance index is following:
Input voltage: DC:11～14V, 15A can directly connect automobile cigarette lighter seat (12V) or receives on the 12V automobile storage battery.
Output voltage: 15～24VDC is adjustable, has 7 adjustable gears.
The scope of output DC: 15/16/18/19/20V, maximum current 6A; 22/24V, maximum current 4A
Panel designs:
Front and back panels deft design, the uniqueness, elegant in appearance of this invention instrument.
On the plate, the aviation plug of one four pin is provided in front, has realized the external input of 12VDC, total insurance of battery main switch and 15A is arranged, three branch control switches are respectively applied for three different voltages with different output of control (12V, 15～24V, 15～24V).
In front on the plate, power access end of 1 group of banana plug is provided also, also can have realized 12VDC output or the input of 12VDC is provided to transducer through this terminal.
On the plate, also arranged the LED power on light in front, when battery main switch and three branch control switch opens, the red LED power supply indicator of corresponding each output can be bright.
The utility model on the plate, is furnished with voltage output end of the aviation plug of three four pins in the back: the output socket of a 12VDC output socket and 2 15～24V, each lead-out terminal has the insurance of a 5A respectively, in order to guarantee the Electrical Safety of instrument.
5.4 method for using:
At first confirm the operating voltage of institute's each instrument of service test measuring system, the by-pass cock with power supply changeover device pushes the correspondent voltage outgoing position then, the loam cake that closes then, locking.(instrument initial condition, the output position of the switch of two conversion chips all is made as 20V, can satisfy the need for electricity of common instrument basically).
The 12VDC power supply is linked into the external input socket of this power supply changeover device, the number of required power supply is adopted front end, notebook computer and other transducers that need supply power receive respectively on the correspondent voltage output interface and can use.
Wiring definition: on each input of front and back panels, lead-out terminal, the mode of connection of definition positive and negative electrode.
Points for attention:
The external input voltage of this utility model can not surpass 15V, otherwise can burn conversion chip.When the automobile storage battery undertension, the normal output of instrument can reduce.
The utility model can provide the power supply of the required multiple different voltages of automobile test measuring system easily; Use simply, conveniently, high efficiency is to solve in the motor road test; The very useful instrument of data acquisition system power issue has great application prospect.
