Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-2, the antenna position automatic adjusting device of the present invention includes: an antenna 2, at least three position measuring units 3, a position adjusting unit 4 and a position control unit 5.
Each position measuring unit 3 is fixed to the side surface of the antenna 2, and measures position data of the antenna 2 with respect to the beacon 1 in the track, that is, coordinates of each point in a coordinate system.
Setting a coordinate system: setting the direction parallel to the track as the X direction; according to a Cartesian coordinate system, the direction which is parallel to the ground plane of the track and vertical to the X direction is the Y direction; the direction perpendicular to the X-direction and the Y-direction constituting the plane is the Z-direction. Therefore, the vertical direction is the Z direction; the horizontal direction includes an X direction and a Y direction.
The position control unit 5 and the position adjusting unit 4 are fixed on the rail transit vehicle body 6, and the position adjusting unit 4 is connected with the antenna 2. A position adjusting unit 4 to achieve adjustment of the antenna 2 in six degrees of freedom.
On one hand, the position control unit 5 substitutes the position data measured by each position measuring unit 3 into a plane fitting equation to fit a plane of the current position of the antenna; on the other hand, the best position of the preset known antenna distance beacon is substituted into a plane fitting equation, and a plane of the best position of the antenna is fitted; and the difference between the plane of the current position of the antenna and the plane of the optimal position of the antenna is sent to the position adjusting unit 4; the position adjusting unit 4 adjusts the position of the antenna according to the difference until the difference is zero. The plane fitting equation is prior art and will not be described in detail here.
Referring to fig. 3, the method for automatically adjusting the antenna position of the present invention includes the following steps:
in step S1, each position measuring unit 3 measures position data of the antenna 2 with respect to the beacon 1, and transmits the data to the position control unit 5.
In step S2, the position control unit 5 substitutes the position data measured by each position measurement unit 3 into a plane fitting equation to fit a plane of the current position of the antenna.
In step S3, the position control unit 5 substitutes the preset optimal position of the antenna 2 from the beacon 1 into a plane fitting equation to fit a plane of the optimal position of the antenna.
In step S4, the position control unit 5 calculates a difference between the plane of the current position of the antenna and the plane of the optimal position of the antenna, and sends the difference to the position adjustment unit 4.
In step S5, the position adjustment unit 4 adjusts the antenna position according to the difference until the difference is zero.
For example: knowing that the best position of the antenna 2 from the beacon 1 is Z, taking 3 points as an example, the Z is taken into a plane fitting equation, and a plane equation of the best position of the antenna is fitted. Setting the position values of three points acquired by the three position measurement units 3 as Z1, Z2 and Z3; and fitting a plane equation of the current position of the antenna according to the plane fitting equation. And (3) making a difference between the plane equation of the current position of the antenna and the plane equation of the optimal position of the antenna, calculating a difference value of the two planes, sending the difference value to the position adjusting unit 4, and adjusting the position until the two planes are overlapped, namely the difference value is a zero position.
