Device processed 63 is electrically connected with the motor of the first electric pushrod 13 and the second electric pushrod 14 respectively, display screen angle controller and the
The motor electrical connection of four electric pushrods 44；
Table top lifting controller 62 is intelligent controller, and elevating control knob, platform are provided with table top lifting controller 62
The scale division value of the adjustable height of the control of face lifting controller 62 can be set by programming, and lectern is improved with according to different use demands
The control accuracy of the adjustable height of table top 11；Sensor 64 can be the optical sensors such as infrared ray sensor, laser-correlation sensor,
Can also be other type sensors；The present embodiment preferably use Kinect sensor, Kinect sensor include high definition camera,
RF transmitter and infrared camera, Kinect sensor are arranged on the relevant position of the protecting cover 13 at dais 1, and Kinect is passed
Sensor is gathered by its internal high definition camera, RF transmitter and infrared camera in the folding sign region of protecting cover 13
And obtain high-definition image and depth information image, it can be determined that whether there is object within region is indicated, once find that someone exists
Folding region someone of protecting cover 13 has object, then judge that the folding of protecting cover 13 is blocked, and Kinect sensor soon will
The signal that the folding of protecting cover 13 is blocked is sent to CPU microprocessor 611, and warning drive module 613 is according to CPU microprocessor
611 control command drives attention device to send acousto-optic or voice messaging prompting, and alarm is carried out with to situation；Protecting cover folding
Controller 63 receives the control command of CPU microprocessor 611, and controls drive device to stop driving the automatic pass of protecting cover 13
Close, while controlling the first electric pushrod 13 of drive device and the motor reversal of the second electric pushrod 14 (to be closed relative to protecting cover 13
The motor of the first electric pushrod 13 and the second electric pushrod 14 is rotated forward and rotated when closing), the weight of protecting cover 13 that will have been closed
It is new to open, not only prevent from crushing user causing the accident, can also avoid because have object be sandwiched in wherein and caused by equipment damage
It is bad；Until personnel leave sign region or object be moved out of sign region, Kinect sensor immediately will collection signal send
To CPU microprocessor 611, protecting cover 13 just starts automatic closing function, effectively prevent nearby personnel or object and is pressed from both sides accidentally.
