Description

Integrated telemetering micro-power consumption surface displacement monitor based on stay wire displacement meter

Technical Field

The invention relates to a surface displacement monitor, in particular to an integrated telemetering micro-power consumption surface displacement monitor based on a stay wire displacement meter, and belongs to the field of monitoring.

Background

The prior art is mostly realized by using a stay wire displacement meter which is used as a sensor. The displacement sensor of the pull wire displacement meter converts the mechanical displacement into a measurable, linearly proportional electrical signal. When the object to be measured generates displacement, the steel rope connected with the object to be measured is pulled, and the steel rope drives the sensor transmission mechanism and the sensing element to synchronously rotate; when the displacement moves reversely, the rotating device in the sensor automatically retracts the rope and keeps the tension of the rope unchanged during the extension and retraction of the rope, thereby outputting an electric signal which is in direct proportion to the movement amount of the rope. In order to ensure that the stay wire displacement meter works for a long time, a corresponding power supply system, such as a solar power supply facility, is required to be configured; support protection devices such as vertical rods (for mounting solar panels) and equipment boxes (for placing storage batteries and the like) are needed; in order to ensure that the displacement change data can be sensed in time, data acquisition and transmission equipment needs to be configured, for example, the displacement change data acquired by the acquisition circuit is transmitted to a remote platform in a GPRS (general packet radio service), 4G, NB-IOT (internet of things) mode and other modes, and the change of the displacement is monitored in real time.

A typical stay wire displacement monitoring system is characterized in that a core sensor stay wire displacement meter is fixed on a basic positioning point, a steel wire rope of the stay wire displacement meter is pulled out and fixed on other measuring points, such as a measuring point 1, when the length of a stay wire between the basic positioning point and the measuring point 1 is changed, the displacement of the ground between the basic positioning point and the measuring point 1 is changed, the reason for the change is considered to be that the ground where the measuring point 1 is located slides downwards, the change can be sensed by the stay wire displacement meter, and data are wirelessly transmitted to a measuring platform. However, the prior art has the following disadvantages:

(ii) power supply problems. In order to ensure that the stay wire displacement meter can work for a long time and record the long-term change trend of the position of the monitoring point, reliable power supply must be provided. The commercial power is not feasible, because general geological disaster monitoring points are located in the field, the nearby commercial power supply conditions are not met, and in addition, the possibility of power failure of the commercial power is high, and the bit line displacement accumulated data can be cleared to zero due to the power failure. The problem of power supply is usually solved by using a solar power supply system, and each monitoring point is equipped with a reliable set of solar power supply equipment, including a solar panel, a storage battery, a solar power supply controller and the like.

② the problem of installation and construction. In order to ensure the operation of the stay wire displacement sensor, besides ensuring the power supply, the necessary protection is provided for the operation of the sensor. For example, to use the steel pole setting to support solar cell panel, use the equipment box protection electronic equipment, the pole setting is fixed subaerial through the concrete, and displacement meter of acting as go-between needs plus protective housing etc.. These operations greatly increase the difficulty of installing and using the equipment.

And redundancy of data. The monitoring of geological disaster point earth's surface displacement is a long-term process, and the displacement daily change volume or the annual change volume of monitoring is very little, and under the above-mentioned condition that has power supply, the frequency of general monitoring system data acquisition is very high, for example many data per second, and a large amount of data are transmitted to the monitoring platform, and data do not basically change in the short time moreover, just caused a large amount of wasting of resources for the platform.

And fourthly, the implementation cost is high. The core sensor is "displacement meter of acting as go-between", nevertheless will make its steady operation, has additionally been equipped with solar cell panel, storage battery, solar energy power supply controller, steel pole setting, protective housing, still needs the ground of digging deeply during the installation moreover, uses the concrete fixed ground cage. And these costs are even far in excess of the acquisition costs of the pull-wire displacement meter itself.

Anti-theft and anti-damage. The stay wire displacement monitoring device can be easily damaged or stolen (a battery is stored) no matter where the installation position is located, as long as the stay wire displacement monitoring device is within the moving range of people. When stolen or destroyed, the user cannot obtain information and provide any clue for detection.

Compared with the prior art, the invention has the following advantages:

(1) integration, greatly reduced installation degree of difficulty and purchasing cost.

Through integration, auxiliary assembly such as basic foundation, steel pole setting, equipment box has been saved, except reducing the equipment fixing degree of difficulty, also greatly reduced purchase and installation cost.

(2) The integration improves equipment safety protection ability.

All parts are integrated together through a shell, so that the protection of equipment becomes simpler, all equipment, circuits and the like can be protected equally only by purchasing materials with high hardness and making waterproof and dustproof, and the device is suitable for being used in the field for a long time.

(3) The low-power consumption design improves data availability factor, reduces the energy consumption.

By adopting a low-power design concept, the MCU (micro control unit) enters a dormant state at regular time and simultaneously turns off surrounding electronic components. Aiming at the characteristics of field long-term monitoring, after the MCU is awakened at regular time, data is firstly sorted once after data acquisition is finished, the data variation is judged, the times of uploading a monitoring platform are reduced for tiny variation or invariance, the data volume is reduced, the energy consumption is greatly reduced, and the use efficiency of the data is also improved.

When the vibration frequency reaches a certain value, for example, the vibration frequency exceeds 5 times within 1 minute continuously, the artificial damage is considered to possibly exist, alarm information is sent to the platform, the patrol personnel checks the equipment condition on site, and the problem is found and is timely treated.

For example, the stay wire displacement sensor is provided with one MCU, the data acquisition and transmission equipment is also provided with the own MCU, and the solar power supply controller is also provided with the own MCU, so that the MCU is matched with the MCU to realize low power consumption, the economic cost is increased, and the operation efficiency is low.

(6) External wake-up mechanism in sleep state.

Because geological disaster earth surface displacement generally has the characteristic of long-term monitoring, namely the change of the displacement is tiny, the quantity and the speed of the change of the displacement can be calculated only by long-term measurement and recording. In this situation, the invention can enter the dormant state at regular time, and can carry out high system integration. However, for monitoring the ground surface displacement of the geological disaster, when the disaster occurs, the equipment must be capable of waking up in time, collecting and transmitting data, and sending out early warning information. The device must be provided with an external wake-up mechanism.

The invention has two mechanisms to realize external wake-up: the magnetic encoder comprises a magnetic encoder, a main shaft, a MCU, a magnetic sensor, a sensor and a controller, wherein the magnetic encoder is provided with four Hall sensors around, the MCU can sense the rotation of the main shaft in a sleeping state, and when the rotation angle exceeds a preset angle, the MCU is awakened to enter a normal state; and secondly, a photoelectric coded disc is arranged on one side of the radial magnet close to the photoelectric encoder, the photoelectric encoder is arranged, and when the main shaft rotates, the MCU is awakened to enter a normal state through the photoelectric encoder. The two methods can adjust the displacement change value of the awakening MCU according to actual conditions.

(7) And the flexibility of selecting a transmission mode is increased through the modular design.

When the circuit main board PCB is designed, the data transmission part is separated, a power supply, a signal control interface and a data interface are reserved, and the data transmission mode can be changed according to actual needs by replacing a transmission module (a plug-in mode). For example, the modes of NB-IOT and ZigBee with low power consumption, GPRS with wide coverage, 4G with large data transmission quantity, WiFi for trunking transmission and the like meet the actual monitoring requirement.
