Virtual instrument system

Abstract

The invention discloses a virtual instrument system, which comprises a navigation device, a display module, a voice module, a first controller and a memorizer, wherein the navigation device is used for navigation, and the display module is used for displaying various information; the voice module is used for voice prompt; and the first controller is used for processing the navigation information of the navigation device and controlling the display module to display and the voice module to carry out corresponding voice broadcast; and the memorizer is used for providing internal memory for the first controller. The navigation device, the display module, the voice module, the memorizer and a second controller are respectively connected with the first controller. As the virtual instrument system adopts the navigation device, the display module, the first controller, the voice module, the memorizer, a CAN (Controller Area Network) receiving-transmitting module, a sensor detection module, the second controller and a backlight regulating module, a virtual instrument not only can display running parameters about the car running state but also can display the real-time navigation information, the attention of a driver is not divided, the driver needs not to lean to one side or turn to view or inquire the navigation information, and the safety in the driving process is increased.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a virtual instrument system. Background technique [0002] In the field of instrumentation testing, virtual instrumentation technology perfectly combines image processing technology and instrumentation technology, which opens a new page for modern instrumentation technology. [0003] Traditional instruments and meters have the ability of input and output, and the instruments have functions such as buttons, knobs, scales, and graphics. Inside the instrument, there are digital-to-analog / analog-to-digital converters, microprocessors, memories, buses, etc., and all circuits are fixed. After the instrument inputs the signal, it obtains the structure through internal processing for the reference of technicians. The virtual instrument takes image processing as the core, and makes full use of the powerful display, processing and storage capabilities of the controller to simulate t...

Problems solved by technology

[0004] In the field of automotive instrumentation, traditional instruments such as mechanical instruments or pointer instrument panels with LCD screens are generally used, but only display the driving parameters related to the running status of the car, and do not have real-time navigation functions. If users need navigation, they must In addition, navigation equipment is added, which brings great inconvenience to users.

There are two ways to increase navigation equipment, one is the car DVD navigator, the use of the car DVD navigator occupies a narrow space in the car to a certain extent, and the driver must turn sideways to see the inside of the navigator when using it. map, which increases the risk for the driver to drive; the other is a portable navigator, which also occupies a narrow space in the car. The navigator is not fixed firmly so that it is difficult for the driver to operate, and there is a great potential safety hazard
