Abstract
The utility model provides a boats and ships heave campaign measuring apparatu mainly includes top cap 2, barrel 4, 10 triplexs of bottom, and 2 outer tops of top cap installation external connection ware 1, and the dress is hugged closely at 2 inside top walls of top cap to power strip 3, and the distance is far away relatively to the sensitive inertia device of temperature ratio, IF board 5, nuclear core plate 6, generating line board 7 are all installed on barrel 4, and bottom 10 is gone up the installation and is added table subassembly 8 and MEMS top 9. Having three power module on the power strip, scribbling thermal conductive grease on it, make power module more can hug closely at the inside top wall of top cap, go out the heat transfer that the system produced through heat -conduction, this kind of structure heat dispersion is good, has improved instrument precision and stability.
Description
Technical field
The utility model relates to a kind of instrument measuring boats and ships heave and attitude.
Background technology
Boats and ships heave movement measuring instrument is a kind of instrument measuring boats and ships heave and attitude, and the angular speed mainly utilizing MEMS gyro to measure and the linear acceleration of accelerometer measures carry out the heave and the attitude that calculate boats and ships, are then exported by outconnector.At present, measure device many employings upper, middle, and lower part split-type structural of boats and ships heave movement, corresponding top cover, cylindrical shell, bottom respectively, all printed boards such as power panel, bus bar plate, IF plate, core board are all mounted on cylindrical shell, bottom is installed MEMS gyro and Jia Biao assembly, top cover installs aerial lug.Problem is that power panel is arranged on middle cylinder, nearer apart from inertia device, because the power module thermal value on power panel is larger, radiating rate is slower, it is poorer than the precision and stability of more sensitive inertia device as MEMS gyro and Jia Biao assembly to cause temperature, reduces the performance of boats and ships heave movement measuring instrument.
Utility model content
For solving heat dispersion of the prior art, improve the precision and stability of instrument, the utility model provides a kind of boats and ships heave movement measuring instrument, is arranged on by power panel on the inwall of top cover, perfect heat-dissipating, accuracy of instrument and stability higher.Its technical scheme is as follows:
A kind of boats and ships heave movement of the utility model measuring instrument, mainly comprises top cover 2, cylindrical shell 4, bottom 10 3 part, and aerial lug 1 is installed at the outer top of top cover 2, and the top upper wall being contained in top cover 2 inside is close to by power panel 3; IF plate 5, core board 6, bus bar plate 7 are all arranged on cylindrical shell 4, bottom 10 is installed and adds table assembly 8 and MEMS gyro 9.The aerial lug 1 at the outer top of top cover 2 is responsible for correspondence with foreign country; The power panel 3 of inner roof wall there is female connector, is responsible for internally power supply, and to outconnector transmission information; The power module of power panel scribbles thermal grease conduction, makes power module more can be close to the top upper wall of top cover inside, by heat transfer, the heat that system produces is passed, this structure perfect heat-dissipating.
Principle of work: the different power demands of the MEMS gyro in boats and ships heave movement measuring instrument, accelerometer, bus bar plate, IF plate, core board and information export and realized by inside and outside connector and power panel and changed.The specific works process of boats and ships heave movement measuring instrument is: power panel is powered to each device by female connector, accelerometer measures boats and ships linear acceleration, and the current signal then exported by IF plate degree of will speed up meter is converted into pulse signal; MEMS gyro measures the angular speed of boats and ships, and core board acquisition angle rate signal and linear acceleration pulse signal real-time resolving go out the current heave of boats and ships and attitude information, and are exported by inside and outside connector.
beneficial effect:
Compared with prior art, the beneficial effect of a kind of boats and ships heave movement of the utility model measuring instrument is: because power panel is arranged on the roof of top cover inside, perfect heat-dissipating, and power panel distance to temperature than more sensitive inertia device as MEMS gyro and Jia Biao assembly are relatively far away, thus improve accuracy of instrument and stability.
