Embodiment
4 collision blocks are installed on antenna rotary shaft, in the pitching of antenna and the limit place of horizontal level 4 limit switches are installed, the main purpose of limit switch is offside in order to prevent mechanism kinematic, when antenna carries out the power-off restoration operation, also carries out reset operation as reference point simultaneously.Seek the star control unit and rotate and direction, and pass through the state of Transistor-Transistor Logic level interpretation servomechanism limit switch by pulse signal and level control step motor.Once collision block is run into limit switch, limit switch promptly sends a signal to motor control module, and motor control module sends signal to motor drive module, and driver module quits work, and operation is waited in the entire antenna stop motion.
Automatic recycling and control method is:
1.) the beginning reclaimer operation stops all stepping motors
2.) host CPU obtains level and the pitching umber of pulse that Electric Machine Control CPU sends, and be fetched into host CPU again and calculate the result who obtains the antenna present level azimuth and the angle of pitch,
3.) host CPU returns zero pulse to Electric Machine Control CPU transmission level and counts A,
4.) Electric Machine Control CPU starts horizontal motor, and the umber of pulse parameter A that record Electric Machine Control CPU sends to horizontal motor in the host CPU begins to carry out from subtracting calculating, and oneself is kept to till zero up to send out umber of pulse A,
5.) after the parameter A of recording level transmission umber of pulse in the host CPU was kept to 0 certainly, host CPU sent a low level to Electric Machine Control CPU,
6.) Electric Machine Control CPU stops horizontal motor movement, issues high level of host CPU again, waits for next step operation
7. after) host CPU received signal, beginning was returned zero required pulse to Electric Machine Control CPU transmission pitching and is counted B,
8. after) Electric Machine Control CPU received the instruction that host CPU sends out, Electric Machine Control CPU began to start pitching motor, begin equally to carry out from reducing,
9.) after the B parameter of record pitching transmission umber of pulse in the host CPU was kept to 0 certainly, host CPU sent a low level to Electric Machine Control CPU,
10.) Electric Machine Control CPU stops the pitching motor motion, issues high level of host CPU again.
