At the functions such as vibration acquisition, moonscope, difference resolving, wireless communication, transmission coding/decoding, battery management.
The integrated circuit board, mainboard center are obliquity sensors, and three axial rakes value collected participates in posture solution
It calculates, the axis that can be eliminated between tri- axis of XYZ is poor.
The internal battery group, be by 4 section, 18650 standard lithium battery group at battery pack, in addition to can charge and discharge design,
Convenient for users to being replaced to battery.
The understructure is located at outer casing bottom, is separate structure with shell, can flexibly be dismantled according to construction condition
Replacement, then be fixed to pedestal on the monitoring objective of abnormity together with shell by screw or bandage device, to meet difference
Angle and installation requirements of different shapes.
The invention has the benefit that realizing big-dipper satellite reference observation station and flowing respectively on a Differential positioning device
Two kinds of observation station function, while taking into account positioning accuracy, effectively save equipment investment cost reduces the repetition wave in construction
Take.Its built-in high-precision, highly sensitive innovative cavity type vibration detection device simultaneously, the vibration acquired by data processing unit
Integral is used as Primary Reference, is modified to the difference result of big-dipper satellite, to improve positioning accuracy and reliability.Separately
Outside, casing rigidity design rationally, sleet when can avoid its core component by external impacts, and successfully managing outdoor mounted and
The pedestal of Dust guard requirement, shell is flexible design for disassembly, to meet different installation requirements and usage scenario.
