Each positioning module includes motor, push rod and signal receiving unit；The signal receiving unit, the horse
Reach, the push rod is sequentially connected；
The signal transmitter unit and the signal receiving unit two-way communication link.
(1) automatic balancing arrangement suitable for projecting apparatus is body structure, described suitable for the automatic flat of projecting apparatus
Weighing apparatus device is body structure, and the projection end of the projection light machine is arranged on the outer wall of the body structure, the governor circuit
Module, the motor and the signal receiving unit, which are arranged in the box house, the tank floor, sets each positioning
The push rod of module.The push rod is expansion link.
(2) quantity of the multiple positioning module is four, respectively three positive location modules and a Passive Positioning
Module.
Wherein, the push rod in four positioning modules is separately positioned at four drift angles of body structure bottom surface, close to projection
Two bottom surface drift angles of ray machine and the bottom surface drift angle away from projection light machine and at projection light machine left back set and are respectively provided with one
The push rod of individual positive location module, the bottom surface drift angle away from projection light machine and at projection light machine right back sets Passive Positioning
The push rod of module.
If being push rod A and push rod B close to the push rod that two bottom surface drift angles of projection light machine are set, away from projection light machine and place
The push rod that bottom surface drift angle at projection light machine left back is set is push rod C, and push rod A is arranged side by side with push rod C, push rod B and quilt
The push rod of dynamic positioning module is arranged side by side.
The function of being applied to the automatic balancing arrangement of projecting apparatus each part in the utility model is：
(1) gravity sensor, for obtaining angle inclination information of the projection light machine in some plane；
(2) CPU control units, for detecting the data of gravity sensor and producing command signal according to data；Control is single
Member produces two kinds of command signals：First, gravity sensor exports a left and right angle-data in real time, and control unit produces first and referred to
Make signal, two, gravity sensor export a upper and lower angle-data in real time, control unit produces the second command signal.
(3) motor, for driving push rod to move；
