Problems solved by technology

For the relatively small-sized three-axis sensor HMC1043, which is embargoed in China, it is difficult to buy in the market, and another three-axis sensor HMC1053 is worth 600 yuan in the market, and the cost is relatively expensive. There is an urgent need for cheap and low-cost three-axis measurement devices.

Embodiment Construction

[0025] combine figure 1 , figure 2 , an attitude measurement device applied to a high-speed rotating projectile, including a power input module 1, a reference voltage module 2, a signal conditioning module 4, an A / D conversion module 5, a circuit board bottom plate 6, and an intermediate embedded plate 7. The power input module 1 converts the external voltage into a constant voltage of 5V, and the reference voltage module 2 converts 5V into a reference voltage through a reference conversion chip, and provides it to the amplifier and the analog-to-digital converter. Two two-axis sensors 8 and 9 are respectively placed on the circuit board bottom plate 6 and the middle embedded plate 7 to form a three-dimensional coordinate, and two axes and one axis 9 of the two-axis geomagnetic sensor 8 are used to form three-axis sensors perpendicular to each other. The sensor uses the magnetoresistance effect to generate geomagnetic information and transmits it to the signal conditioning m...

Abstract

The invention provides an attitude measuring device applied to a high-speed rotating projectile body. The attitude measuring device comprises a power supply input module for providing working voltage, a circuit bottom board, two two-axle sensors, a middle insert plate and an A/D conversion module for converting a sensor signal into a digital signal, wherein one surface of the circuit bottom board is provided with a first two-axle sensor; the middle insert plate is arranged on the ridge surface of the circuit bottom board; a second two-axle sensor are arranged on the middle insert plate; projection of the original point, on a measuring coordinate system of the second two-axle sensor, of a measuring coordinate system of the first two-axle sensor is superposed with the original point of the measuring coordinate system of the second two-axle sensor.

Description

technical field [0001] The invention relates to a technique for measuring the intensity of the earth's magnetic field, in particular to an attitude measuring device applied to a high-speed rotating projectile. Background technique [0002] At present, there are many technologies that can be used for the flight attitude parameters of projectiles at home and abroad. For example, the sun azimuth sensor method and the inertial measurement combination calculate the attitude angle of the projectile by measuring the angular velocity of the projectile; Acceleration to calculate the attitude angle of the projectile, these methods are only suitable for the roll angle test of the projectile, but if it is used as supporting equipment for some low-cost suppressive ammunition such as rockets and gun-launched missiles It will require expensive cost, and for high-rotation bombs, the current inertial devices cannot meet the requirements in range and accuracy. Therefore, it is imminent to de...
