if yes, then step S106 is carried out to send out a first-stage early warning;
then, the video monitoring and measuring instrument expands the monitoring range of the periphery of the point to be measured which sends out the first-stage early warning, carries out remote video addition real-time monitoring on the point to be measured, measures and records the three-dimensional space coordinate information of the point to be measured, simultaneously collects the field video image in real time, and establishes a real-time three-dimensional space digital model of the added point to be measured through a three-dimensional space algorithm;
then step S108 is carried out, according to the established real-time three-dimensional space digital model, displacement variation and displacement direction of the added point to be measured are calculated, and the whole displacement variation range and displacement direction of the peripheral area of the point to be measured are obtained;
then step S109 is performed to judge whether the whole displacement and the variation range of the peripheral area of the point to be measured are larger than the preset range;
if yes, the process finally proceeds to step S110 to issue a second-level alarm.

Referring to fig. 5, in this embodiment, a problem that data collected by a device cannot be timely, effectively and conveniently sent to a data collection center server is solved. In the existing market, data reporting of most of the inclinometers is basically sent to a data acquisition center server in a wired network mode, and a small number of the inclinometers collect data lines into a local data acquisition unit in a short-distance wireless mode (such as zigbee and Lora) and then send the data lines to a data acquisition center server in a wired network mode through the data acquisition unit.

In order to solve the problem that the data collected by the inclinometer cannot be timely, effectively and conveniently sent to the data collection center server, the inclination angle sensor 120 adopts a narrow-band Internet of things module, the narrow-band Internet of things module can directly send the collected data to the data center server side through a wireless cellular network of an operator, and the bottleneck that the early inclinometer sends back the data in a wired network mode is opened.

When the tilt sensor 120 is at rest, it is only under the action of gravity, so the angle between its vertical axis of gravity and the sensitive axis of the sensor is the desired tilt angle. The inclination sensor and the external MCU support SPI serial digital interface communication, measured data are sent to the external MCU in a digital quantity mode, and the MCU carries out filtering and denoising processing on the measured data to obtain inclination angle data. Wherein, the tilt angle sensor 120 adopts SCA100T-D02 double-shaft tilt angle sensor 120 of VTI technology, which can measure the tilt angles of two surfaces of X and Y axes, the resolution of the measured tilt angle can reach 0.002 degrees, and the precision can reach 0.01 degrees.
Referring to fig. 6, in the embodiment, in order to solve the problem that the conventional inclination measuring terminal cannot distinguish whether the inclination is a forward inclination or a lateral inclination, the inclination measuring terminal further includes an electronic compass 160, the electronic compass 160 is connected to the main control MCU110, and the electronic compass 160 is used for detecting the inclination direction of a monitoring point of a body to be detected.

The direction information can be calculated by using the principle.
In this embodiment, in order to early warn people around the object to be detected in time, the inclinometer terminal further includes an alarm indicator lamp, and the alarm indicator lamp is connected to the main control MCU 110; the main control MCU110 is further configured to determine whether the inclination information exceeds a preset threshold, and if the inclination information exceeds the preset threshold, send an early warning message to the data collection center server, and control the warning indicator to light up. When the main control MCU110 judges that the inclined displacement exceeds the preset threshold value, the alarm indicating lamp is controlled to be turned on, surrounding personnel can be alerted in time, and meanwhile, early warning information is sent to the data acquisition center server, so that the working personnel can timely deal with the danger that the body to be detected is likely to collapse.
In this embodiment, in order to reduce power consumption, the main control MCU110 is further configured to control the tilt sensor 120 to enter a sleep mode within a preset time and enter a low consumption mode when it is determined that the tilt angle of the monitoring point of the body to be detected has not changed. When the main control MCU110 determines that the inclination angle of the to-be-detected body is not changed, the inclination sensor 120 is controlled to enter a sleep mode within a preset time, and simultaneously enter a low consumption mode to reduce power consumption, and when the preset time is elapsed, the inclination sensor 120 is waken up and enters a working mode to obtain the inclination angle of the to-be-detected body, and determine whether the to-be-detected body is inclined.
