Further, flying quality comprises the image data of the sensor in the service data of flight controller and unmanned vehicle.
Further, be preset with encipheror in flight controller, the decrypted program in computing machine corresponds to this encipheror.
Compared to existing technology, beneficial effect of the present invention is: by above-mentioned log recording and read method, by in the journal file of write storer after flying quality encryption, again by the storer in flight controller with the mode carry of similar USB flash disk to computing machine, namely ensure that the security of log content, also achieve log content that is convenient and that take out rapidly in unmanned vehicle.
Accompanying drawing explanation
Fig. 1 the present invention is based on the log recording of flight controller and the process flow diagram of read method.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
With reference to figure 1, the present invention is applied in unmanned vehicle, unmanned vehicle comprises flight controller, and multiple pen recorder and sensing device, such as gyroscope, barometer, temperature sensor and GPS device etc., storer in flight controller is generally FLASH memory, less but the data stable storage of capacity, the controling parameters called for flight controller is preserved in storer, and for the journal file etc. of record flight data, flight controller can control unmanned vehicle by calling controling parameters, the data of detection and service data can be recorded to the journal file in storer by each pen recorder simultaneously in unmanned vehicle and sensing device.Present embodiments provide a kind of safety and easily based on log recording and the read method of flight controller, comprise the following steps:
Steps A: by flight controller by the journal file in write storer after the encryption of the flying quality of unmanned vehicle.
Unmanned vehicle is in flight course, flight controller can produce control data, pen recorder in unmanned vehicle and sensing device also can Real-Time Monitorings generate image data and be sent in flight controller, the image data unified definition that the control data generated by flight controller and monitoring generate is flying quality, after flight controller obtains flying quality, by the encipheror be preset in wherein, flying quality is encrypted, then according in the journal file in the template style write storer preset.The file layout of journal file is * .log, and log recording is wherein preserved in table form, such as, can be following form:
| poweron | flightcount | sequencenumber | parameter |
| Record 1 | Record 1 | Record 1 | Record 1 |
| … | … | … | … |
Step B: by USB connecting line by the storer carry in flight controller in computing machine.
USB is set in the storer in flight controller and drives file, flight controller also provides the USB interface be electrically connected with storer simultaneously, then storer just can by USB connecting line as USB flash disk carry in computing machine, there will be corresponding disk drive in computing machine, user just can directly be operated the file in storer by this disk.Further, except USB connected mode, can also be set to other exchanges data connected mode, such as storer can be connected with computing machine by SATA connected mode.Therefore, when unmanned vehicle completes flight, when user needs the journal file taken out wherein, only need just directly to obtain journal file by data line connected storage and computing machine, do not need software supporting specially to obtain journal file.Wherein, with USB interface, microcontroller is become USB flash disk type of service for prior art, be specifically record in the patent of CN200910045659.8 at application number, flight controller of the present invention is equivalent to microcontroller, does not repeat them here.
Step C: the journal file in storer is taken out in computing machine.Due to journal file can be taken out easily in this step, just need the security considering journal file, therefore just need in step to arrange encrypting step, make journal file possess good security.
Step D: utilize corresponding decrypted program in computing machine to load journal file, by decrypted program, journal file is decrypted, obtains the log content after deciphering.
Owing in step the flying quality in journal file having been carried out cryptographic operation, with regard to needing, the flying quality of encryption is decrypted in this step.Therefore, just need in a computer decrypted program is installed, and the encipheror in this decrypted program and flight controller is supporting encryption and decryption program, as what kind of encryption and decryption program of selection, be set according to the requirement of user or the production standard of manufacturer.
By above-mentioned log recording and read method, by in the journal file of write storer after flying quality encryption, again by the storer in flight controller with the mode carry of similar USB flash disk to computing machine, namely ensure that the security of log content, also achieve log content that is convenient and that take out rapidly in unmanned vehicle.
