Problems solved by technology
[0004] However, to artificially perform precise temperature compensation on the highly sensitive inclinometer, a very harsh test environment is required: both the temperature rise must be considered, and micro-shocks or air flow in the temperature compensation environment must be avoided as much as possible. The workload of temperature compensation is relatively large.
[0005] In addition, in order to avoid the temperature drift of the inclinometer from start to normal work, the inclinometer needs to be warmed up for a period of time from start to normal work, which takes up a certain amount of working time and reduces work efficiency

The invention discloses a high precision inclinometer and an intelligent temperature compensation system, and relates to the field of inclination angle measurement or inclination angle monitoring. The inclinometer comprises an inclination angle measuring chip and the intelligent temperature compensation system, and the intelligent temperature compensation system comprises a microcontroller, a heating sheet and a refrigeration sheet when a temperature measuring device is integrated in the inclination angle measuring chip; and when no temperature measuring device is integrated in the inclination angle measuring chip, the intelligent temperature compensation system comprises the microcontroller, the heating sheet, the refrigeration sheet and a temperature sensor, and the temperature sensor is arranged at the lateral edge of the inclination angle measuring chip. The microcontroller controls starting / stopping of the heating sheet and the refrigeration sheet and grading loading / unloading of power to obtain a temperature drift array; and when the inclinometer is used, the microcontroller automatically completes temperature compensation. The temperature compensation precision is effectively improved, the temperature compensation workload is reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the field of inclination measurement or inclination monitoring, in particular to a high-precision inclinometer and an intelligent temperature compensation system. Background technique [0002] With the development of science and technology, the world has gradually entered the era of the Internet of Things. The sensor is the main way and technical means to obtain various information in the natural and engineering fields, and its performance is directly related to the accuracy and authenticity of the measurement results. As a sensor for measuring inclination, the inclinometer is widely used in machinery, civil engineering and various engineering. [0003] The material used for the inclination measurement chip in the inclinometer has its specific temperature properties. Therefore, when the inclinometer is working normally, it will be affected by the heat generated by the internal circuit and the change of the external air tempera...
