Step 402: the smaller value of first parameter value and the second parameter value is obtained, by controlling first switch and second
The state of switch makes the main collection antenna switch to the corresponding connection status of the smaller value.
That is, when first parameter value is less than or equal to the second parameter value, first parameter value and second
Smaller value in parameter value is the first parameter value, since the connection status of the corresponding main collection antenna of the first parameter value is the first connection
State, thus, control first switch closure and control second switch disconnection；It is greater than the second parameter value in first parameter value
When, the smaller value in first parameter value and the second parameter value is the second parameter value, due to the corresponding main collection of the second parameter value
