Problems solved by technology

[0002] At present, the angle sensors used in heavy-duty machinery in construction machinery are generally conventional angle sensors. In the strong vibration environment of construction machinery, it is often impossible to obtain accurate angle values, and its anti-interference and anti-vibration performance is poor. Due to the harsh working environment, the service life of the sensor is low
Some GPS and fiber optic gyroscopes are also used in construction machinery, high-precision detection systems, but their cost is high, and installation and maintenance are inconvenient

Embodiment Construction

[0011] Examples, see attached figure 1 , The sensor housing 6 of the non-contact angle sensor for heavy-duty machinery is made of copper, which can effectively avoid electromagnetic interference around the sensor. A groove is arranged at the bottom of the upper inner cavity of the sensor housing 6 , and an isolation ring 17 is installed in the groove, and a circuit board 13 is installed in the sensor inner cavity above the isolation ring 17 . Connecting shaft 12 is housed with bearing 9 in the lower inner cavity of sensor housing 6, is provided with magnetite mounting groove 12-1 at the top center of connecting shaft 12, and magnetite 7 is housed in magnetizing mounting groove 12-1. A sensor chip 16 is connected to the circuit board 13 facing the magnet 7 , and an acceleration sensor 15 and a gyroscope module 14 are connected to the upper middle of the circuit board 13 . A rubber covering layer 11 is sealed between the inner bottom of the sensor housing 6 and the outer circum...

Abstract

The invention belongs to a device for detection angle in the field of engineering machinery and especially relates to a non-contact angle sensor for heavy duty machinery and an angle correction method. The bottom portion of a cavity in the upper portion of a sensor housing (6) is provided with a groove; the groove is internally provided with an isolation ring (17); the sensor cavity (6) above the isolation ring (17) is equipped with a circuit board (13); the center of the cavity in the lower portion of the sensor housing (6) is provided with a connection shaft (12) through a bearing (9); and an acceleration sensor (15) and a gyroscope module (14) are arranged in the middle portion above the circuit board (13). The circuit board (13) comprises a multi-way switch (13-1), an amplifier 1 (13-2), an analog-digital converter (13-3), a digital signal processor (13-4), a digital-analog converter (13-5), an amplifier 2 (13-6), a voltage and current transformer (13-7), an analog signal output and a digital signal output. The non-contact angle sensor is fast in calculating speed, high in reliability, convenient to install, flexible and convenient to operate, long in service life and low in cost.

Description

technical field [0001] The invention belongs to equipment for detecting angles in the construction machinery industry, in particular to a non-contact angle sensor for heavy-duty machinery and an angle correction method. Background technique [0002] At present, the angle sensors used in heavy-duty machinery in construction machinery are generally conventional angle sensors. In the strong vibration environment of construction machinery, it is often impossible to obtain accurate angle values, and its anti-interference and anti-vibration performance is poor. Due to the harsh working environment, the service life of the sensor is low. Some GPS and fiber optic gyroscopes and high-precision detection systems are also used in construction machinery, but their cost is high and installation and maintenance are inconvenient. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and provide a non-contact ang...
