Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is a course of work schematic diagram of the present utility model;
Fig. 3 to Fig. 9 is that antenna carries out the schematic diagram that all angles are rotated.
Embodiment
Below in conjunction with drawings and the specific embodiments the concrete composition of the present utility model and the course of work are elaborated.
With reference to shown in Figure 1, the utility model provides a kind of mobile antenna apparatus, comprise antenna 1 (using plate aerial among this embodiment), master controller 2, GPS navigation system 3, stepping motor 4, base 5, support 6, gyroscope 7 and compass 8, this kind antenna assembly is by the satellite-signal positional information of at first default corresponding each longitude and latitude, each satellite programming, and in the car and boat traveling process control antenna 1 all the time towards this satellite-signal, thereby guarantee the excellent reception signal strength signal intensity, make car and boat also can watch satellite programming in the process of moving.
Stepping motor 4 comprises elevation angle stepping motor 41 and azimuth stepping motor 42, its control end all connects support 6, under the control of master controller 2, regulate the rotation direction and the angle of support 6, realize the comprehensive rotation of antenna 1, can receive satellite-signal clearly all the time to guarantee antenna 1.
Store the positional information of the signal of corresponding each frequency range in the master controller 2, because each satellite programming and frequency range are to concern one to one, as long as therefore know the required satellite programming of watching, can find the positional information of its signal, and may command support 6 turns to towards this position, and the signal strength signal intensity that antenna 1 is received is the strongest.
Below in conjunction with Fig. 2 the concrete course of work of the present utility model is done an explanation.
(1) at first carries out the initialization of system, comprise the software in the master controller 2 and the initialization of antenna 1, make antenna 1 be in initial position;
(2) GPS navigation system 3, compass 9 detect the longitude and latitude and the deviation angle information of current location, and send in the master controller 2;
(3) master controller 2 is according to the frequency range of the satellite programming that will watch, read its positional information (because the frequency range of each satellite programming is unique at current longitude and latitude, therefore determine that frequency range is this program of lockable), and according to deviation angle calculated difference, be scaled the step number of advancing of stepping motor 4, control elevation angle stepping motor 41 and azimuth stepping motor 42 are adjusted into the relevant position with support 6, can be with reference to figure 3 to shown in Figure 9, be illustrated under the control of master controller 2, support 6 carries out the schematic diagram of level and vertical direction rotation;
