6.) signal that receives after the up time limit switch closure of host CPU turns back to host CPU, and calculate level by host CPU and return zero data, and send to Electric Machine Control CPU,
7.) the horizontal motor of Electric Machine Control CPU startup makes antenna be turned back to level zero point, and Electric Machine Control CPU carries out calculatings of successively decreasing of horizontal pulse number simultaneously, up to horizontal pulse count parameter be decremented to zero till, and send a high level to host CPU,
8.) host CPU receives the Electric Machine Control cpu signal and just knows that levels operation finishes, and issues the signal that Electric Machine Control CPU begins the pitching motor operation,
9.) start pitching motor, this moment, pitching motor began to move downward always, till antenna bumps against limit switch downwards, host CPU receives the signal of coming to lower position switch and just knows that pitching finishes, and issue Electric Machine Control CPU low level, Electric Machine Control CPU will stop to move downward operation
10.) system parameters of host CPU begins to reset at this moment,
11.) the end reset operation.

Embodiment
Set in advance two parameter A, B writes down the umber of pulse of CPU to horizontal motor and pitching motor transmission respectively, has reached the purpose of tracking antenna motion state at any time.When reclaiming, the recording level motor sends the parameter A elder generation computing of umber of pulse, and the horizontal level of antenna is recovered to the reference position earlier, and the B parameter of computing record pitching motor again is recovered to datum mark with the pitch position of antenna.Finish the reclaimer operation of entire antenna.
This automatic reset control method is:
1.) system cut-off, after restoring electricity again, reset operation begins,
2.) stop all stepping motor operations, at first whether system test broke: host CPU begins to detect the data in the Electric Machine Control CPU, when sending a low level (0-2.2V), motor control chip gives host CPU, then host CPU determines that system broke, the data of temporarily depositing in the Electric Machine Control CPU are fallen clearly
3.) after host CPU receives the low level that motor control chip beams back, send a high level to Electric Machine Control CPU, Electric Machine Control CPU control motor moves clockwise, and the collision block on clockwise direction bumps against the up time limit switch,
4. after) host CPU received signal after the up time limit switch closure, host CPU just extracted the power-off restoration data in the permanent internal memory of Electric Machine Control CPU,
5.) host CPU sends a high level to Electric Machine Control CPU, and Electric Machine Control CPU gives parameter A with the power-off restoration data assignment that reads, and B after finishing, sends a high level to host CPU, waits for next step operation;
6. after) Electric Machine Control CPU obtains the operational order of host CPU transmission, begin to start the levels operation motor, motion counterclockwise, the parameter A of the recording level umber of pulse among the Electric Machine Control CPU begins to carry out from reducing, certainly be kept to 0 up to A, at this moment, Electric Machine Control CPU sends a high level to host CPU, waits for next step operation;
7.) host CPU receives the Electric Machine Control cpu signal and just knows that levels operation finishes, and issues the signal that Electric Machine Control CPU begins the pitching motor operation,
8.) start pitching motor, this moment, pitching motor began to move downward always, till the lower limit collision block of antenna bumps against limit switch, host CPU receives the high level of coming to lower position switch and just knows that elevating movement finishes, and issue Electric Machine Control CPU low level, Electric Machine Control CPU will stop to move downward operation
