Embodiment Construction
[0011] The accompanying drawings disclose the specific structure of the present invention in a non-limiting manner, and the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, an inclination measurement system with temperature compensation includes an inclination sensor, an AD converter, a single-chip computer, a temperature sensor, and a host computer. The output signal of the inclination sensor is AD converted by the AD converter, and the inclination data after the AD conversion It is sent to the single-chip microcomputer, and the single-chip microcomputer simultaneously receives the temperature signal sent by the temperature sensor. The single-chip microcomputer includes an initialization module and a calibration module. The initialization module initializes the received inclination data. The calibration module performs zero point calibration on the inclination sensor and performs temperature accor...

The invention discloses a dip angle measuring system with a temperature compensation function. The dip angle measuring system comprises a dip angle sensor, an AD converter, a single chip microcomputer, a temperature sensor and an upper computer, wherein output of the dip angle sensor are subjected to AD conversion by the AD converter; dip angle data after being subjected to the AD conversion are input into the single chip microcomputer; the single chip microcomputer is in data transmission with the upper computer through wireless signals and comprises an initialization module and a calibration module, wherein the initialization module is used for initializing received dip angle data, and the calibration module is used for carrying out zero calibration on the dip angle sensor, carrying out temperature drift compensation and nonlinear compensation according to current data and transmitting a final result to the upper computer in a data transmission manner through the wireless signals. According to the dip angle measuring system with the temperature compensation function, output data of the dip angle sensor can be subjected to temperature compensation, burr removal and amplification, so that the dip angle measurement accuracy and resolution are effectively improved.
Description
Technical field [0001] The invention relates to a technique for applying a sensor to tilt angle measurement, in particular to a tilt angle measurement system with temperature compensation. Background technique [0002] In related industries such as automatic control engineering design and geodetic surveying, it is often necessary to perform inclination measurement on a certain plane or datum, or perform automatic level adjustment, especially in automatic control, which often requires dynamic horizontal control of an object. The instrument is required to be able to automatically and dynamically track the horizontal inclination angle. In some high-precision measurement systems, it is also required to quickly level the system or perform rapid and high-precision measurement of the inclination angle of certain devices and the horizontal plane. [0003] At present, most of the existing inclination measurement systems use the inclination sensor to sense the inclination signal, and the out...
