Abstract
The utility model discloses a driving navigator detection system based on a CAN (Controller Area Network) bus. The driving navigator detection system comprises a signal generator, a CAN bus and a plurality of detection ports formed in the CAN bus, wherein the signal generator is formed by a touch screen, a screen display control module, an MCU (Micro-programmed Control Unit), a power supply managing module and a CAN interface; and the CAN interface is connected with a high-speed CAN transmitter-receiver and a low-speed CAN transmitter-receiver. According to the driving navigator detection system disclosed by the utility model, in a working process, complicated operations of different modules are simplified; the driving navigator detection system is convenient, simple and rapid, and the testing efficiency is improved; the driving navigator detection system has the important popularization meaning; the device can accurately test functions of a car audio-navigation all-in-one machine; the quality of the product of the car audio-navigation all-in-one machine is improved; and the possibilities of fault after the car audio-navigation all-in-one machine is mounted on the real car are greatly reduced.
Description
Technical field
The utility model relates to electronic navigation instrument processing detection range, especially a kind of traffic navigation instrument detection system based on the CAN bus.
Background technology
Because large scale integrated circuit and the development of reading and writing electronic chip at a high speed, traffic navigation instrument in the market not only possesses the effect to auto navigation, has had abundant extendability function.And present audio-visual navigation one function is presented at the functional parts state of automotive interior on its display screen, makes the driver have operation more easily, grasps the state of car body each parts in service more exactly.But the Function detection about audio-visual navigation all-in-one needs each functional module of automobile to carry out response test respectively, because it is more that the navigating instrument function shows, such testing process is troublesome poeration not only, the process redundancy, and efficient is very low, has seriously blocked the lifting of productive capacity.
So the applicant designs a cover detection system, whether each functional module of simulated automotive is sent various control signals complete effective with each function that detects the navigating instrument finished product.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the applicant has researched and developed a kind of traffic navigation instrument detection system based on the CAN bus through long-term practical exploration.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of traffic navigation instrument detection system based on the CAN bus, comprise signal generator, CAN bus and be arranged on some detection port on the described CAN bus, described signal generator is shown control module, MCU control module, power management module and CAN interface and is formed by touch-screen, screen, and described CAN interface is connected with high-speed CAN transceiver and low speed CAN transceiver.The operating system that this device adopts is windows CE6.0, can support to move demand with low-speed device at a high speed from bottom hardware, and can realize low speed CAN transceiver and the one-touch switching of high-speed CAN transceiver.
Described high-speed CAN transceiver control sends igniting and shows that signal, steering wheel angle variable signal, radar for backing car show signal and parking brake variable signal, and described low speed CAN transceiver control sends air-conditioner temperature, wind-force and steering angle variable signal.
The utility model adopts the touch-screen control signal, has designed friendly UI operation interface, can realize multi-object, the multifunctional all test.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, numerous and diverse operation between disparate modules that the course of work of the present utility model is easy, convenient and simple quick, improve testing efficiency, have great dissemination;
2, the utility model can be tested the function of the audio-visual navigation all-in-one of automobile more exactly, promotes the quality of the audio-visual navigation all-in-one of automobile product, greatly reduces the audio-visual navigation all-in-one of automobile and is installed to the probability that breaks down behind the automobile real vehicle;
3, the utility model is provided with some detection port in described CAN bus, can be by sending a signal, and the finished product to be detected to a plurality of carries detects simultaneously, has greatly improved detection speed.
Description of drawings
Fig. 1 is the structural representation that the many carries of the utility model detect.
Fig. 2 is the module diagram of signal generator of the present utility model.
Embodiment
Below by a most preferred embodiment, the technical program is elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of traffic navigation instrument detection system based on the CAN bus, comprise signal generator, CAN bus and be arranged on some detection port on the described CAN bus, can be by sending a signal, the finished product to be detected to a plurality of carries detects simultaneously.
As shown in Figure 2, described signal generator is shown control module, MCU control module, power management module and CAN interface and is formed by touch-screen, screen, and described CAN interface is connected with high-speed CAN transceiver and low speed CAN transceiver.Described high-speed CAN transceiver control sends igniting and shows that signal, steering wheel angle variable signal, radar for backing car show signal and parking brake variable signal, and described low speed CAN transceiver control sends air-conditioner temperature, wind-force and steering angle variable signal.The operating system that this device adopts is windows CE6.0, can support to move demand with low-speed device at a high speed from bottom hardware, and can realize low speed CAN transceiver and the one-touch switching of high-speed CAN transceiver.
During real work, by the touch-screen input control signal, select high-speed CAN transceiver or low speed CAN transceiver to carry out functional detection.The utility model can also be selected automatic detection, i.e. the automatic test of one-key operation repertoire is heavily examined or individual event when detecting for needs, can select manual test, namely a certain function is operated separately and realizes independent functional test.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
