Abstract
The invention relates to a method for testing stability of navigation equipment. The method comprises the following steps of: 101, acquiring state data output in the process of executing each action from a processor of the navigation equipment through an external processor and storing the state data; 102, photographing an image displayed by a display of the navigation equipment by utilizing a camera and storing the image when the external processor executes the step 101; and 103, judging whether the navigation equipment is normal through the external processor according to the state data, and when the operation of the navigation equipment is judged to be abnormal, writing a point-in-time into a monitoring video output by the camera in the step 102 and storing the point-in-time. According to the method, unmanned monitoring in a test required to be finished for a long time can be realized, the point-in-time which corresponds to the monitoring video can be associated after the test according to the output time recorded in the system, the monitoring video in which a problem occurs is replayed, the aim of rapidly positioning the problem is fulfilled, the efficiency is high, and a few manpower resources are required.
Description
Technical field
The present invention relates to method of testing, particularly a kind of navigator stability test method.
Background technology
The vehicle mounted guidance product all needs to carry out a series of stability test in development, guarantees the stability of product.But because stability experiment all needs for a long time (for example, the test of pot machine), if the arrangement personnel monitor whole process of the test always, can cause waste of human resource like this, reduce work efficiency.
Summary of the invention
Based on this, being necessary to provide a kind of can finish automatically, need not the navigator stability test method of staff's on-site supervision.
A kind of navigator stability test method may further comprise the steps:
Step S101, status data and the storage of output when obtaining it and carry out each action from the processor of navigator by a ppu;
The image that the display that step S102, described ppu utilize a camera to absorb described navigator in execution in step S101 shows and storage; And
Step S103, whether ppu is normal according to the operation of described status data navigator, and when judging that navigator moves when undesired, the write time point is stored again in the monitor video of camera output in step S102.
Further, described navigator stability test method also comprises according to user instruction and utilizes a step that is connected to before and after the described time point of display playback on the described ppu at least one minute monitor video.
The present invention can be implemented in no worker monitor in the experiment that need to finish for a long time, can be associated with according to the output time point of system log (SYSLOG) on time point corresponding to monitor video after the experiment, realize the monitor video when playback goes wrong, reach the purpose of quick positioning question phenomenon, efficient is high, needs human resources few.
Description of drawings
Fig. 1 is the structural drawing of a kind of navigator system for testing stability of the present invention.
Fig. 2 is the process flow diagram of navigator stability test method in one embodiment of the present invention.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing navigator stability test method of the present invention is described in further detail.
Navigator stability test method of the present invention is based on that as shown in Figure 1 framework realizes, this test macro comprises that mainly a ppu and is connected to that camera on the ppu and display realize.Wherein navigator to be tested mainly comprises the display of navigation host (being the processor of navigator) and navigator.In the present embodiment, ppu links to each other with the navigation host of navigator by universal asynchronous receiving-transmitting transmitter (Universal Asynchronous Receiver/Transmitter, UART) interface.Camera is fixed on directly over the display of navigator, is used for taking the shown image of display of navigator, thereby forms monitor video.
Navigator stability test method of the present invention mainly may further comprise the steps:
Step S101 obtains status data (trace data) and the storage of processor output when carrying out each action of navigator from the processor of navigator by a ppu;
Image and storage that step S102, ppu utilize the display of camera picked-up navigator to show in execution in step S101;
Step S103, ppu judges according to described status data whether the navigator operation is normal, when judging that navigator moves when undesired, in step S102, write navigator in the monitor video of camera output and move abnormal time point and store again; And
Step S104, ppu utilize at least one minute the monitor video in time point front and back of a display playback according to user instruction.
In the present embodiment, when status data represented that navigator is being restarted or the navigator system resources consumption high or crash (judging by the CPU usage in the status data and memory consumption data), ppu judged that the navigator operation is undesired.The method of write time point is for to be inserted into temporal information in the monitor video image with the video character superimposing technique.
Please refer to Fig. 2, the step S101 of the inventive method comprises step S1011, S1012 and step S103 in practical operation.Step S102 comprises step S1021, S1022 and S1023.And step S103 can be decomposed into step S1031 to S1033.
Concrete, among the step S1011, ppu is reads status data from navigation host.Among the step S1031, ppu judges whether to satisfy the condition (namely whether Condition Matching) of output time point according to the status data that receives, if satisfy the condition of output time section, and execution in step S1032 then, otherwise execution in step S1012.Among the step S1032, the time point during ppu output condition coupling also is the time point that the abnormal situation of operation occurs navigator.Among the step S1012, ppu is stored in status data in one storer.
Among the step S1021, the image that ppu utilizes the display of camera picked-up navigator to show.Among the step S1022, ppu judges whether the input of free point, if having, and execution in step S1033, otherwise execution in step S1023.Among the step S1033, ppu is the write time point in the current monitor video of camera output.Among the step S1023, external memory storage is stored in treated monitor video in one storer.When the staff need to check the monitor video of time point, ppu comprised at least one minute the monitor video in time point front and back of user selection automatically by display, reached the purpose of quick positioning question phenomenon.Preferably, one minute monitor video before and after the playback time point can be pinpointed the problems a little automatically.
After using the inventive method, it is on duty to need not the staff when navigation product is carried out stability test, after finishing test, the staff can be associated with according to the output time point of system log (SYSLOG) on time point corresponding to monitor video, realize the monitor video when playback goes wrong, reach the purpose of quick positioning question phenomenon, efficient is high, needs human resources few.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
