Abstract
The utility model relates to an automotive steering wheel state monitor, which comprises a steering wheel, an angle self-adjusting transmitter/receiver, an analog quantity signal processing board, a universal serial bus (USB) 7336B board card, an industrial tablet personal computer and a pointer instrument, wherein the angle self-adjusting transmitter is arranged on a mechanical rotating shaft of the steering wheel; one path of detected voltage signal is input into the pointer instrument for displaying a rotating angle of the steering wheel through the angle self-adjusting receiver; the other path of voltage signal is input into the USB 7336B board card through the analog quantity signal processing board and is connected with the industrial tablet personal computer through a USB interface; and the industrial tablet personal computer is arranged on an operating table inside an automobile. By adopting the angle self-adjusting transmitter/receiver and the pointer instrument or the industrial tablet personal computer, the rotating angle of the steering wheel can be clearly and intuitively displayed in front of a driver.
Description
Technical field
The utility model relates to a kind of monitor, particularly a kind of vehicle steering state monitor.
Background technology
Along with growth in the living standard, automobile becomes popular indispensable instrument.Therefore, people have more requirement to the development of auto trade, and particularly for the beginner, the motoring condition of vehicle is one of their problem of relatively worrying, such as the direction of vehicle.The beginner often holds the anglec of rotation of inaccurate bearing circle in driving procedure, cause potential safety hazard for self and traffic.The product of bearing circle condition monitoring aspect does not also have now, if the product of the number of turns and the angle of direction indication dish is arranged, can bring a lot of convenience.Therefore, bearing circle connects the synchro transmitting set, the voltage signal that detects is leaded up to the pointer meters that receiver connects and is shown, filtering and voltage stabilizing are then carried out by the analog signals disposable plates of designed, designed in another road, be input to the USB7336B integrated circuit board, connect industrial touch computer again and show, software adopts the labview programming, is convenient to upgrading and debugging.
Summary of the invention
The utility model is for the poor problem that causes potential safety hazard of bearing circle control sense, a kind of vehicle steering state monitor has been proposed, adopt synchro as vehicle steering angle displacement pickup, and concatenation pointer instrument and the real-time display direction plate-like of industrial touch computer attitude.
The technical solution of the utility model is: a kind of vehicle steering state monitor, comprise bearing circle, synchro transmitting set, analog signal conditioning plate, USB7336B integrated circuit board, industrial panel computer, synchro receiver, pointer meters, the synchro transmitting set is installed on the bearing circle mechanical rotating shaft, bearing circle moves, the stator side output analog quantity voltage signal of synchro transmitting set, voltage signal is leaded up to the stator side of synchro receiver, the rotor driven sideway swivel, the rotor-side rotating shaft is connected to pointer meters, pointer display direction disc spins angle; Another road of voltage signal then by the analog signals disposable plates, is input to the USB7336B integrated circuit board, and by USB interface and industrial panel computer connecting communication, industrial panel computer is installed on the operator's station of automotive interior again.
Described analog signals disposable plates is the analog signal processing circuit that comprises multichannel.
Described analog signal processing circuit is the discharge circuit that two op amps consist of cascade, connects two stabilivolts of connecting between mouth and the ground.
The beneficial effects of the utility model are: the utility model vehicle steering state monitor, and adopt synchro and pointer meters or industry to touch panel computer, can be with more clear and intuitive being presented in face of the driver of the bearing circle anglec of rotation.
Description of drawings
Fig. 1 is the utility model vehicle steering state monitor structured flowchart;
Fig. 2 is analog signal processing circuit figure in the utility model vehicle steering state monitor;
Fig. 3 is the lavbiew software flow pattern.
The specific embodiment
Vehicle steering state monitor structured flowchart comprises bearing circle 1, synchro transmitting set 2, analog signal conditioning plate 3, USB7336B integrated circuit board 4, industrial panel computer 5, synchro receiver 6, pointer meters 7 as shown in Figure 1.Synchro transmitting set 2 is installed on bearing circle 1 mechanical rotating shaft, along with the movement of bearing circle, and the stator side of synchro transmitting set 2 output analog quantity voltage signal.Voltage signal is leaded up to the stator side of synchro receiver 6, the rotor driven sideway swivel, and the rotor-side rotating shaft is connected to pointer meters 7, pointer display direction disc spins angle; Another road of voltage signal then by analog signals disposable plates 3, is input to USB7336B integrated circuit board 4, is connected with industrial panel computer 5 with USB interface again.Industrial panel computer 5 is installed on the operator's station of automotive interior, and chaufeur can come the operation monitoring instrument by manual palpation panel computer 5; Open LABVIEW software and come real-time display direction dish corner and direction.
The analog signal processing circuit figure of vehicle steering state monitor as shown in Figure 2, the amplifier chip uses RC4558D, have 8 pins, 4 and 8 pin be respectively power supply-12V and+12V, 2 and 3 pin are the input end of first via amplifier, 1 pin is mouth, and 5 and 6 pin are the input end of the second tunnel amplifier, and 7 pin are mouth.2 op amps consist of the discharge circuit of cascade, and R105 is adjustable potentiometer, regulate its resistance value and can change output voltage, and when surpassing 4.8V voltage, because stabilivolt D101 and D102 are arranged, output voltage is stabilized in 4.8V.
Be illustrated in figure 3 as the labview program flow diagram.Device initialize is at first carried out in the program operation, equipment normally then stops, wait for the user instruction interface otherwise enter, the user can select to withdraw from, or enter into the manually opened software of user after the user interface, the USB7336B integrated circuit board begins image data, and changes into the bearing circle anglec of rotation by the software computing and be presented in real time in face of the user.Display interface has exit button, and the user only needs manually just can withdraw from software.
