3 and 4 under the action of its internal circuit, and enters the two ends of the power supply input of the wireless receiving control circuit and the trigger circuit, and the wireless receiving control circuit and the trigger circuit are in a power-on working state. In wireless receiving control circuit, wireless transmission control circuit: when the audience enters the dome 106 of the stereoscopic dome movie device body 1 and is in place on the seat 107, the manager presses the first wireless transmitting key S1 of the wireless transmitting circuit module A4, so that the wireless transmitting circuit module A4 can transmit a first path of wireless closing signal, the wireless receiving circuit module A1 receives the first path of wireless closing signal, 3 pins of the wireless receiving circuit module A1 output high level, the high level is subjected to voltage reduction and current limitation by the resistor R and enters the base electrode of the NPN triode Q, the NPN triode Q is conducted with the collector and outputs low level to enter the negative power supply input end of the relay K, and then the relay K is electrified to attract the three control power supply input ends and the three normally open contact ends of the relay K to be closed respectively; because the three normally open contact ends of the relay K and the three power input ends of the two sets of electric cylinders M are respectively connected through the leads, the two sets of electric cylinders M can be electrically operated at the moment, the piston rods of the electric cylinders M push the middle part of the rear side of the ball curtain frame 101 to move forwards, then the front part of the ball curtain frame 101 moves forwards downwards, and the front lower end of the ball curtain 106 can slowly approach the ground so as to cover all the auditorium seats 107 in the ball curtain 106. When the front end of the ball curtain 106 moves forward and downward, the lower end of the rear side of the ball curtain frame 101 rotates along the hinge point of the bearing seat 103, the cylinder bodies of the two sets of electric cylinders 2 and the front connecting plate 21 of the piston rod rotate along the hinge points of the two fixed seats 105 and the two supporting seats 104 respectively, and the ball curtain frame 101 is guaranteed not to be blocked in the forward and downward movement. In this is novel, when the lower extreme did not contact ground before ball curtain 106, side interval was less than 1.5 meters behind photoelectric switch A2's the detecting head front end interval ball curtain 106, and photoelectric switch's 3 feet do not have output, relay K2 keeps losing power, and NPN triode Q's collecting electrode and relay K's negative pole power input end intercommunication like this, and relay K keeps getting the electric actuation, so, electric jar M just can continue to keep operating condition just so. When the front lower end of the ball screen 106 is about to contact the ground, and the distance between the front end of a detection head of the photoelectric switch A2 and the rear side end of the ball screen 106 is larger than 1.5M, 3 pins of the photoelectric switch output high level to enter the positive power input end of the K2, the relay K2 is electrified to attract the control power input end and the normally closed contact end to open, so that the collector of the NPN triode Q and the negative power input end of the relay K are open, the relay K loses power and no longer attracts the three control power input ends and the three normally open contact ends to open, the electric cylinder M loses power and no longer works, the ball screen 106 does not move any more, and a spectator seat is just covered at the lower end of the ball screen 106. Through the aforesaid, this novel ability is in practical application, and the managers no longer carries out any operation after pressing wireless transmission circuit module A4' S first wireless transmission button S1, and after the preceding lower extreme of follow-up ball curtain 106 just contacted ground, ball curtain 106 just no longer moved, has reached automated control purpose.

Fig. 1, 2 shows, this novel audience 'S sight finish, when needing to open ball curtain 106, the administrator presses wireless transmission button S2 of second of wireless transmitting circuit module a4, then, wireless transmitting circuit module a4 can launch the wireless closed signal of second way, wireless receiving circuit module a1 receives its 5 feet output high level behind the wireless closed signal of first way, the high level is through resistance R1 step-down current-limiting entering NPN triode Q1' S base, NPN triode Q1 switches on the negative pole power input that collector output low level got into relay K1, then, relay K1 gets electric actuation its three control power input and three normally open contact end of actuation closed respectively. Because, the three normally open contact end of relay K1 and each three power input end of two sets of electric jar M are connected through the wire respectively, and with in the three normally open contact end of relay K, wherein two contact wiring modes are opposite, so two sets of electric jar M get the electric work back this moment, its piston rod can drive ball curtain frame 101 rear side middle part rearward movement, and then, the anterior rearward movement that makes progress of ball curtain frame 101, like this the ball curtain before the lower extreme can slowly with ground pull open the interval, the auditorium seat 107 is whole to leak slowly in the ball curtain 106. When the front end of the ball curtain 106 moves backwards and upwards, the lower end of the rear side of the ball curtain frame 101 rotates along the hinge point of the bearing seat 103, the cylinder bodies of the two sets of electric cylinders 2 and the front connecting plate 21 of the piston rod rotate along the hinge points of the two fixed seats 105 and the two supporting seats 104 respectively, and the ball curtain frame 101 is guaranteed not to be blocked in the forward and upward movement. In this is novel, when the interval that ball curtain 106 front end and auditorium pull open is greater than about 2 meters, the manager presses wireless transmission button S2 of second of wireless transmitting circuit module A4 once more, then, wireless transmitting circuit module A4 can launch the wireless signal of opening a way of second, its 5 feet can stop outputting the high level behind the wireless signal of opening a way of second is received to wireless receiving circuit module A1, then, relay K1 loses the electricity and no longer gets the electricity actuation its three control power input end of actuation and three normally open contact end and open a way respectively, and then two sets of electric jar M lose the electricity, its piston rod no longer drives ball curtain frame 101 rear side middle part rearward movement, spectator just can walk out in the ball curtain 106. This novel managers can conveniently pass through remote control, and control ball curtain moves down along the pin joint, and the ball curtain can play better sight shadow effect with whole covers of auditorium in ball curtain lower extreme like this. The photoelectric switch of the trigger circuit can automatically turn off the power supply of the electric cylinder when the lower end of the ball curtain is in contact with the ground, so that the wireless remote control time of workers is reduced, and convenience is brought to the workers. After the film is viewed, the manager can control the rise height of the spherical screen along the hinged point through remote control, so that the spectators can conveniently walk out of the spherical screen. The novel cinema exhibition support can provide powerful technical support for the audience to be personally on the scene and the movie, and is favorable for improving the benefit of a cinema. Resistor R, R1 is 1K; the model of NPN triode Q and Q1 is 9013; relays K, K1, K2 are DC12V relays, relay K, K1 has two power inputs, three control power outputs, relay K2 has two power inputs, two control power outputs.
