Drawings
In order to more clearly illustrate the technical solution provided by the present application, the following description will briefly refer to the accompanying drawings. It will be apparent that the figures described below are merely some embodiments of the application.
Fig. 1 is a flow chart of a radio compass data processing method of the present application.
Detailed Description
In order to make the objects, technical solutions and advantages of the present application become more apparent, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application.
As shown in fig. 1, the radio compass data processing method of ultrashort wave interference provided by the application comprises the following steps:
S1, acquiring a state signal of whether the ultrashort wave platform transmits signals or not.
For the status signal of the ultrashort wave platform, the ultrashort wave platform can generate a status signal when the ultrashort wave platform works, the status signal can be represented by a status word '1', and the ultrashort wave platform sends the status word to the radio compass when the ultrashort wave platform works. Furthermore, the ultrashort wave platform generates a status signal when the transmission is completed or not, the status signal can be represented by a status word "0", and the ultrashort wave platform transmits the status word to the radio compass when the transmission is completed or not.
S2, judging the working emission state of the ultrashort wave platform according to the state signal of the ultrashort wave platform. For example, the radio compass judges the working state of the ultrashort wave platform through a status word "0" or "1" sent by the ultrashort wave platform, when the status word is "1", the ultrashort wave platform transmits signals, and when the status word is "0", the ultrashort wave platform transmits signals completely or does not transmit signals.
When the radio compass judges that the ultrashort wave radio station is transmitting signals, the azimuth resolving data of the radio compass changes along with the true heading/magnetic heading synchronization opposite direction to obtain changed radio compass azimuth resolving data.
For example, if the bearing solution dataset of the radio compass is P (P 1,p2,…,pn), the true heading dataset X (X 1,x2,…,xn), then the bearing solution dataset Q (Q 1,q2,…,qn) varies in opposite directions with the true heading dataset synchronization, wherein,
When the radio compass judges that the ultra-short wave radio station finishes signal transmission or does not perform signal transmission, the azimuth settlement data of the radio compass are resolved according to a normal resolving flow.
S3, outputting the tower azimuth by the radio compass according to the processed azimuth resolving data or the normal azimuth resolving data.
In the application, before the radio compass carries out the resolving of the azimuth resolving data, the azimuth resolving data firstly enters a resolving data smoothing filter for smoothing processing.
According to the radio compass data processing method for ultra-short wave interference, when interference of an ultra-short wave platform is intolerable, the antenna of the ultra-short wave platform is not required to be shifted, the interference problem can be simply, efficiently and low-cost solved by improving the algorithm of the radio compass, so that the radio compass can still output a correct tower azimuth when being interfered.
In addition, the application also provides a radio compass with ultrashort wave interference, which comprises:
the acquisition module is used for acquiring a state signal of whether the ultrashort wave platform performs signal transmission or not;
The data processing module is used for judging the state of the ultrashort wave platform according to the state signal of the ultrashort wave platform, when the ultrashort wave platform transmits signals, the direction resolving data of the radio compass are changed along with the true course synchronization opposite direction to obtain changed direction resolving data, when the ultrashort wave radio station does not transmit signals, the direction resolving data of the radio compass are not processed, and the direction of the tower is output according to the direction resolving data of the radio compass.
The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present application should be included in the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
