As shown in fig. 9, after the shutter door opening switch 30 is pressed, the controller first determines the state of the shutter door driving motor 21, and when the shutter door driving motor 21 is in reverse rotation, it means that the shutter door is in the process of closing, that is, the shutter door opening switch 30 is pressed during the shutter door process, the shutter door driving motor 21 executes a stop command, and when the shutter door opening switch 30 is pressed, the stop switch is equivalent to the stop switch action, so that the shutter door operation switch may not be provided with the stop switch in this case, so as to reduce the cost.
If the rolling shutter door driving motor 21 is in a stop state after forward rotation, the controller again judges whether the second position switch 29 sends out a signal, if so, the rolling shutter door is at the maximum opened position, and the motor 21 does not need to be started; if the second position switch 29 sends a signal or not, the rolling door driving motor 21 rotates forward to open the rolling door 2; checking whether the roller shutter door driving motor 21 is blocked or not every time the roller shutter door 2 is further in front of the period to ensure safety; as does the closing process of the roll-up door 2.
As shown in fig. 10, after the desk lifting switch 32 is pressed, the controller first determines the state of the roller shutter door driving motor 2, and when the roller shutter door driving motor 21 is in a moving state, that is, the roller shutter door is in the process of opening and closing, then the desk lifting motor assembly 7 executes a stop command, and the desk does not move, so as to ensure safety.
When the roller shutter door driving motor 21 is in a stop state, judging whether the second position switch 29 sends a signal again, if no signal is sent, namely the roller shutter door 2 is not opened to the maximum position, the table is lifted, and the risk of collision with the roller shutter door exists, so that an opening program of the roller shutter door 2 is executed, the roller shutter door is opened to the maximum position, then judging whether the second position switch 29 sends a signal again, if yes, judging the movement state of the table lifting motor assembly 7 again, and if the motor 7 is in a reverse rotation state, namely the table is in a descending process, executing a stop command by the motor 7, and under the condition that the small table lifting switch 32 is quite equivalent to the action of the stop switch, the table operation switch can not be provided with the stop switch, so that the cost is reduced; meanwhile, the program can realize the height adjustment of the small table plate; the table descent program operates in the same manner as described above.
