This novel live broadcast, when the live broadcast person is located suitable angle before the camera, when also being in the detection head front end detection scope of pyroelectric detection module A2, the 3 feet of pyroelectric detection module A2 can export the high level and 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, relay K1 is got electric actuation its control power input of actuation and normally closed contact end and is opened a way, relay K2 and K of later stage do not all can get electric actuation so. In practical use, when the live broadcast moves leftwards for a certain angle due to various reasons (for example, the dancing action causes the footsteps to move leftwards), since the body of the live player is no longer in the range of the detection head of the pyroelectric detection module A2, the 3-pin of the pyroelectric detection module A2 stops outputting high level, then the relay K1 is de-energized and no longer attracts the input end of the control power supply and the normally closed contact end to be closed, and then the two sets of pyroelectric detection modules A A3 and A are in an energized working state, when the body of the live broadcast moves leftwards for more than 40 cm (when the body does not exceed 40 cm, the live broadcast can be basically positioned in the proper shooting range of the mobile phone camera), the body of the live broadcast can enter the detection head detection range of the left pyroelectric detection module AA3, and then the 3 feet of the pyroelectric detection module AA3 output high level to enter the input end of the positive power supply of the relay K2, and the relay K2 is electrified to attract the two input ends of the control power supply and the two normally open contact ends of the control power supply to be respectively closed. Because two normally open contact ends of the relay K2 are respectively connected with the positive and negative pole power input ends of the motor reducing mechanism M, the positive and negative pole power input ends of the motor reducing mechanism M can be electrified, and then the power output shaft of the motor reducing mechanism M drives the mobile phone 6, the illuminating lamp H, the pyroelectric detection module A2 and the pyroelectric detection module A (A3, A) to rotate left clockwise through the supporting rod 2, the cross rod 3 and the like, so that the mobile phone camera moves along with the left movement of the body of a live broadcast. When the mobile phone 6 and the like rotate to a proper angle to the left, the live broadcast person can be in a proper angle in front of the detection head of the pyroelectric detection module A2 and is detected by the detection head of the pyroelectric detection module A2, then, the 3 pins of the pyroelectric detection module A2 output high level again, the relay K1 is electrified to attract the input end of the control power supply and the normally closed contact end to open a circuit, then, the two sets of pyroelectric detection modules A (A3 and A) are completely electrified and do not work, the corresponding motor speed reduction mechanisms M are also electrified and do not drive the mobile phone and the like to rotate to the left, the live broadcast person can be ensured to be in a proper angle in front of the mobile phone camera as far as possible, and a good live broadcast shooting effect is achieved.

Fig. 1, 2 shows, in actual use, when the live broadcast person moves certain angle because of various reasons health right, because the live broadcast person's health is no longer in the detecting head scope of pyroelectric detection module a2, 3 feet of pyroelectric detection module a2 stop outputting the high level, and then, two sets of pyroelectric detection modules A A3 and a are in the working condition that gets electricity, when the live broadcast person's health moves to the right and exceeds 40 centimetres (when not exceeding 40 centimetres, the live broadcast person can be in the suitable shooting range of cell-phone camera basically) its health can get into the detecting head detection scope of right-hand member pyroelectric detection module AA, and then 3 feet of pyroelectric detection module AA output the high level and get into relay K anodal power input end, relay K gets electricity and attracts its two control power input ends and two normally open contact ends to be closed respectively. Because, two normally open contact ends of relay K are connected respectively with the negative and positive two-pole power input end of motor reduction gears M, the negative and positive two-pole power input end of motor reduction gears M can be electrified at this moment, and then the power output shaft of motor reduction gears M anticlockwise drives cell-phone 6, light H and heat release electricity detection module A2, heat release electricity detection module A (A3, A) to rotate to the right through bracing piece 2, horizontal pole 3 etc. make cell-phone camera move along with live broadcast person's health and remove. When the mobile phone 6 and the like rotate rightwards to a proper angle, at the moment, a live player can be in a proper angle in front of a detection head of the pyroelectric detection module A2 and is detected by the detection head of the pyroelectric detection module A2, then, 3 pins of the pyroelectric detection module A2 output a high level again, the relay K1 is electrified to attract the input end of a control power supply and the normally closed contact end of the relay to be opened, then, the two sets of pyroelectric detection modules A (A3 and A) are completely electrified and do not work any more, the corresponding motor speed reduction mechanism M is also electrified and does not drive the mobile phone and the like to rotate rightwards, the live player is ensured to be in a proper angle in front of the mobile phone camera as far as possible, and a good live shooting effect is achieved. In this is novel, under the extreme condition, motor reduction gears drive cell-phone etc. clockwise or anticlockwise rotation before the dead point, baffle 10 rear end or front end can contact switch D2, the switch D1's of rear end of limiting plate 11 front end button respectively down, then, switch D2 or D1's button is pushed down its inside contact and is opened a way. Because, two wiring terminals of two switches D2 and D1 are connected in series between the first normally open contact end of relay K2 and the positive power input end of motor reduction mechanism M, the first normally open contact end of relay K and the negative power input end of motor reduction mechanism M through the wire respectively, so motor reduction mechanism M can lose electricity respectively no longer move at this moment, only reverse input power can work, the corner that has prevented motor reduction mechanism M from exceeding 360 degrees, cause power plug wire and supply socket separation etc.. This novel angle of having guaranteed as far as possible between live person and the cell-phone camera in the live is in normal condition, has brought the facility for the user, and has improved the live effect. In the circuit, the resistance of the resistor R1 is 1K; the model of the NPN triode Q1 is 9013; relays K2, K1, K are DC12V miniaturised relays.
