Detailed Description
For a clearer understanding of the technical features, objects, and effects of the present patent, embodiments of the present patent will now be described with reference to the accompanying drawings.
The vehicle-mounted navigation automatic test equipment in the embodiment comprises a rotary table, an inertial navigation device controller, a vehicle posture acquisition device, a GPS signal acquisition and playback device and a high-definition camera.
The vehicle-mounted navigation device is arranged on the rotary table; the vehicle attitude acquisition device is connected with the inertial navigation device controller, and the inertial navigation device controller is connected with the rotary table and used for controlling the rotary table to act; the GPS signal acquisition and playback device is connected with an antenna port of the vehicle-mounted navigation system; the high-definition camera aims at the vehicle-mounted navigation screen and collects the screen state.
When the real vehicle is tested, the GPS signal acquisition and playback device acquires the GPS signal of the place in real time and records the GPS signal; the vehicle attitude acquisition device simultaneously records the vehicle attitude states of different GPS position points, including the vehicle yaw angle of the corresponding position point,
when the vehicle-mounted navigation system is used for indoor simulation testing, vehicle-mounted navigation is placed on the rotary table, the vehicle attitude acquisition device supplies power to the inertial navigation controller, meanwhile, attitude information of a vehicle is transmitted to the inertial navigation controller, the inertial navigation controller controls the running state of the rotary table (as shown in figure 2), information such as vehicle attitude yaw angle and the like is transmitted to the rotary table, the rotary table simulates vehicle attitude and feeds the current state back to the inertial navigation controller, vehicle attitude at different GPS position points is simulated to the navigation system under the actual vehicle road test state, and the navigation system is enabled to run according to the vehicle attitude.
When indoor simulation testing is carried out, vehicle-mounted navigation is placed on a rotary table, a GPS signal acquisition and playback device, a vehicle attitude acquisition device and road video images are synchronized through UTC time, GPS radio-frequency signals are directly connected with a vehicle-mounted navigation antenna interface through a direct connection line, the radio-frequency signals are guided into the vehicle-mounted navigation, the vehicle-mounted navigation automatically decodes and positions the position of a vehicle, an inertial navigation controller controls the action of the rotary table to simulate the vehicle attitude of different GPS position points, namely the vehicle GPS position and the vehicle attitude of the position are integrated in a vehicle-mounted navigation system, and a road condition acquisition camera confirms the matching state of vehicle-mounted navigation positioning and corresponding road conditions again; meanwhile, the acquired real vehicle CAN bus signals are sent to the vehicle-mounted navigation, all conditions of the vehicle-mounted navigation during real vehicle road test operation are met, and the vehicle-mounted navigation automatically operates in a laboratory environment. The scheme of the automatic operation system for the vehicle navigation is shown in figure 3.
The vehicle navigation system automatic test implementation mode is explained as follows: the road condition video acquisition device sends the road condition to the host computer, and high definition digtal camera gathers vehicle navigation system working picture to send the video to the host computer, through host computer processing software, compare vehicle navigation system location position with road condition video road state, confirm whether vehicle navigation location state is correct, whether the automatic detection navigation system appears GPS location mistake, route guide mistake, POI point error display phenomenon simultaneously, automatic contrasts the analysis, and issues the test report. FIG. 4 is a schematic diagram of an automated test.
