Fig. 1 is a schematic structural diagram of a wireless tilt sensing intelligent terminal based on dual triaxial acceleration according to an embodiment of the present application. As shown, the terminal 100 includes:
the low-power-consumption triaxial acceleration sensor 110 and the high-precision triaxial acceleration sensor 120 are respectively used for measuring inclination parameters.
In the present application, the terminal 100 uses the low-power consumption triaxial acceleration sensor 110 (meter) and the high-precision triaxial acceleration sensor 120 (meter), wherein the low-power consumption triaxial acceleration sensor 110 has relatively low precision, but uses less power, and is mainly used for realizing low-precision real-time tilt angle monitoring; the high-precision three-axis acceleration sensor 120 is just opposite, relatively high in precision, but high in power consumption, and mainly used for realizing high-precision inclination angle monitoring; this application adopts two sensor design modes, has increased the redundancy of inclination measurement reliability.
In brief, one of the acceleration sensors is a three-axis acceleration sensor, which works based on the basic principle of acceleration, and the acceleration is a space vector, so that on one hand, to accurately know the motion state of an object, components on three coordinate axes of the object must be measured; on the other hand, in the case where the direction of movement of the object is not known in advance, only the three-axis acceleration sensor is used to detect the acceleration signal. Because the triaxial acceleration sensor is also based on the gravity principle, the triaxial acceleration sensor can realize the inclination angle of a biaxial positive and negative 90 degrees or a biaxial 0-360 degrees, and the later-stage accuracy is higher than that of the biaxial acceleration sensor by being more than 60 degrees of the measurement angle through correction. The unmanned aerial vehicle field is used extensively now. The three-axis acceleration sensor has the characteristics of small volume and light weight, can measure the spatial acceleration, and can comprehensively and accurately reflect the motion property of an object. Most of the existing triaxial acceleration sensors adopt piezoresistive, piezoelectric and capacitive working principles, and the generated acceleration is in direct proportion to the change of resistance, voltage and capacitance and is acquired through corresponding amplifying and filtering circuits.
It should be noted that, the wireless triaxial inclination angle sensing intelligent terminal 100 described in the present application improves the waterproof and dustproof grade due to the absence of the external interface of the wired inclination angle sensor, and is convenient for the use in the construction site.

In brief, after the wireless inclination angle sensing intelligent terminal 100 is activated, the low-power consumption triaxial acceleration sensor 110 is used for monitoring inclination angle changes in real time for most of time; when a preset condition is triggered, if the inclination angle changes to a certain threshold, the high-precision triaxial accelerometer is started to measure, so that effective management and control of power consumption and precision are realized.
In this embodiment, the preset condition includes any one or more of the following combinations:
A. and when the inclination angle parameter acquired by the low-power-consumption triaxial acceleration sensor 110 exceeds a first preset value, starting the high-precision triaxial acceleration sensor 120 to measure the inclination angle parameter so as to further confirm the current inclination angle parameter.
Briefly, when the tilt parameter reaches a certain threshold, a high-precision tri-axial accelerometer is enabled to perform measurements for further confirmation.
B. When the inclination angle parameter acquired by the low-power-consumption triaxial acceleration sensor 110 exceeds a second preset value, the high-precision triaxial acceleration sensor 120 is started to measure the inclination angle parameter so as to precisely monitor the current inclination angle change.
In short, even if the tilt angle parameter or the tilt angle variation does not reach the preset value or the threshold, the wireless tilt angle sensing intelligent terminal 100 will periodically perform the tilt angle measurement and periodically report the tilt angle measurement information.
C. And starting and stopping the high-precision triaxial acceleration sensor according to a certain frequency. That is, in the present application, in addition to the high-precision triaxial acceleration sensor, the high-precision triaxial acceleration sensor 120 is started at regular time, so as to periodically confirm and accurately measure the tilt angle parameter obtained by the low-power-consumption triaxial acceleration sensor 110 in the normal operating state.
D. And receiving an externally transmitted starting instruction aiming at the high-precision triaxial acceleration sensor 120. For example, in a specific construction period, if a constructor needs to pay close attention to a change of an inclination angle, the constructor can send a start instruction for the high-precision triaxial acceleration sensor 120 through a cloud end to realize high-precision detection.
Particularly, this application wireless inclination sensing intelligent terminal 100 has integrateed two triaxial acceleration sensor, under MCU's management, can realize that low accuracy real-time inclination monitoring and high accuracy inclination monitoring are interrupted the organic integration of monitoring, low-power consumption triaxial acceleration continuous operation and monitoring, exceed and change the threshold or awaken up high accuracy triaxial acceleration monitoring inclination regularly, when guaranteeing the precision, increased the measurement redundancy, reduced system's consumption simultaneously.
