It is as shown in Figure 9 that far-end shows control equipment; Comprise wireless audio and video receiver module, wireless data transmission module, image processing board, display screen, input module and battery; The output of input module, wireless audio and video receiver module and wireless data transmission module is connected with image processing board respectively; The output of image processing board is connected with display screen, and image processing board also is connected with battery; Image processing board receive the audio-video signal of wireless audio and video receiver module output and gather, digitized processing; Drive display screen and carry out the image demonstration, also receive the instruction of input module and the control command of sending the User Defined form to the collection transmitting apparatus through the setting frequency range of wireless data transmission module.
Principle of the present invention and effect are described further as follows:
1, spherical shapes, center of gravity is sunk, and reaches the effect of tumbler, is implemented in automatic upright function under any attitude.Scabble ball cover bottom, the end, and feet is arranged, as shown in Figure 2, can effectively improve stability just immediately, overcomes the shortcoming that tumbler is rolled oneself from side to side easily.The common tangent of adjacent two the feet cylindricals of end ball cover is not more than the radius R of supporting surface to the distance L in the supporting surface center of circle, makes the characteristic that does not exceed spherical surface between two feets, thereby can avoid the obstruction of feet to automatic upright process.Hinder just immediately because work as a certain feet, the rolling of device can make it get around feet, between two feets, rolls across, and realizes upright.The position that requires center of gravity G is within the scope that the circular cone OAB that is formed by centre of sphere O and supporting surface is surrounded, and is as shown in Figure 3, be in order to limit the distance that position of centre of gravity departs from rotation, thereby assurance device can be upright.Because when the position, center exceeds this scope, when device stops to roll at the bottom of the supporting surface that scabbles of ball cover can not land, rotating shaft also is in heeling condition, this is neither a stable status, neither our state of wanting.
2, rotating mechanism both can realize that 360 degree rotate, and also can be parked on any angular position.Such as, when functional unit is camera, can take through angle or target that rotating mechanism makes the camera aligning need to take, also can carry out sweeping in week, thereby realize comprehensive shooting surrounding environment with certain rotating speed.
3, device drops on that the ground caved in and locates or do not had when blocking by step, the first-class obstacle of gravelstone, can influence that it is upright automatically.For this reason, balancing weight has been installed on base.When last ball cover or when down ball cover is in recess (as shown in Figure 4) or is blocked (as shown in Figure 5) by barrier, under the driving of motor, rotate on the relative ground of base, and balancing weight produces centrifugal force, makes the device swing, thereby leaves uneven place or barrier.When end cover was in recess (as shown in Figure 6) or is blocked (as shown in Figure 7) by barrier, rotated on the relative ground of the first half, if the first half mass eccentricity; Then produce centrifugal force, make the device swing, if the first half does not have mass eccentricity; Because the quality of base is less relatively, under the situation of rotating suddenly, base still can produce the rotation on relative ground; Make the device swing, thereby leave uneven place or barrier, finally realize upright.
4, the last ball cover of flexible material making, following ball cover and end ball cover encase whole device; Flexible material has damping, anti-effect of falling; The flexible material that has (like expanded material) also has the effect of energy-absorbing; Can greatly reduce device and throw, throwing the acceleration that rolls when landing, thereby the functional unit of protective device itself and inside is not damaged.
5, rotary part has rotary seal, can improve the environmental suitability of device.Because the complexity of environment for use may exist steam, dust, ponding, and these thing accesss to plant are inner, tend to influence the work of functional unit.When dust can be used labyrinth seal, watertight can use O shape circle or the sealing of star circle, airtightly uses the sealing of star circle.
6, after ccd image sensor assembly and microphone transfer light, acoustical signal to the signal of telecommunication respectively, output to the wireless audio and video transmitter module, carry out the live signal emission by setting frequency range by the wireless audio and video transmitter module; Wireless data transmission module wireless receiving far-end shows the control command of the User Defined form of control equipment transmission, and sends instruction the reception of to master control module.The master control module is the front-end control core, comprises functions such as motor-driven, power management, Audio Signal Processing.The master control module is carried out corresponding actions and computing according to remote instructions, like the rotation of motor/stop, automatic scan, mode of operation switching, the control of ccd image sensor electrical component source switch etc.Gather transmitting apparatus and can carry out 360 ° of rotation sweeps, sound, image in 360 ° of scopes on every side are sent to far-end show control equipment.The module of master control simultaneously can send to far-end through wireless data transmission module and show control equipment, information such as work at present state, battery electric quantities so that in time understand the front end operating state in real time.
7, the apparent control equipment of far-end is mainly used in gathering control, display screen driving and image processing, demonstration, the sound playing of transmitting apparatus.Wherein image processing board is the control core; Be responsible for receiving the audio-video signal of wireless audio and video receiver module output; Video, audio signal to receiving gathered, digitized processing; And drive display screen and carry out image and show, be responsible for handling the instruction of input module simultaneously and send the instruction of prescribed form through the setting frequency range forward end of wireless data transmission module, realize gathering the remote control of transmitting apparatus.
