Inclinometer for optimizing temperature compensation time and method

Abstract

The invention discloses a method for optimizing temperature compensation time of an inclinometer. The method comprises the following steps: a single chip control system firstly starts the configuration of a temperature sensor after an inclinometer communication interface receives an acquisition instruction; a conversion starting instruction is sent to the temperature sensor after the configuration is accomplished, and then the single chip control system starts a timer module to time; at this time, the temperature sensor autonomously accomplishes the temperature conversion work, and the single chip control system is in an idle state, and the acquisition on the MEME sensor is started at this time; the single chip control system controls the ADC acquiring circuit and reads the output data of the MEMS sensor, and the MEMS sensor and the temperature sensor perform the acquisition at the same time; when the timing is finished, the single chip control system reads the temperature value converted by the temperature sensor in response to the interruption of the timer, and then performs the temperature compensation computation by use of the temperature value. The problem that that the temperature sensor is long in acquisition time when the inclinometer performs the temperature compensation and modification is solved, the working efficiency is improved, and the precision of the temperature compensation is improved at the same time.

Description

technical field [0001] The invention relates to an inclinometer for optimizing the temperature compensation time, and also relates to a method for optimizing the temperature compensation time of the inclinometer, which belongs to the field of civil engineering and is applied to the structural safety and health monitoring industry. Background technique [0002] The inclinometer is an engineering monitoring instrument that can effectively and accurately measure the deep horizontal displacement. Applying its working principle can monitor the deep horizontal displacement of soil, temporary or permanent underground structures (such as piles, diaphragm walls, caisson, etc.). At present, inclinometers are widely used in engineering projects. The inclinometer sensor part uses a MEMS sensor as the inclination measurement device, and the MEMS sensor is greatly affected by temperature. The inclinometer is a high-precision acquisition device, and the measurement error caused by tempera...

Problems solved by technology

However, DS18B20 acquisition requires a conversion time of 1 second. Each acquisition will consume a lot of time on temperature acquisition, which will affect the data output rate of the inclinometer. In some fields that require high-speed measurement, the current inclinometer cannot meet the requirements.
