Description

An integrated telemetry micro-power surface displacement monitor based on pull-wire displacement meter

technical field

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

Background technique

In the prior art, the "wire displacement meter" is mostly used to realize the implementation, and the cable displacement meter is used as the sensor. The displacement sensor of the pull-wire displacement meter converts the mechanical displacement into a measurable, linearly proportional electrical signal. When the measured object is displaced, pull the steel rope connected to it, and the steel rope drives the sensor transmission mechanism and the sensing element to rotate synchronously; when the displacement moves in the opposite direction, the gyratory device inside the sensor will automatically retract the rope, and the rope will be stretched and retracted. During the process, its tension is kept constant, thereby outputting an electrical signal proportional to the movement of the rope. In order to ensure the long-term operation of the cable displacement meter, it is necessary to configure the corresponding power supply system, such as solar power supply facilities; it needs to have support protection devices, such as poles (installation of solar panels), equipment boxes (place storage batteries, etc.); in order to ensure the displacement change data To be sensed in time, it is necessary to configure data acquisition and transmission equipment, such as using GPRS, 4G, NB-IOT, etc., to transmit the displacement change data collected by the acquisition circuit to the remote platform, and monitor the displacement change in real time.

A typical pull wire displacement monitoring system is to fix the core sensor "pull wire displacement gauge" at the "basic positioning point", pull out the wire rope of the pull wire displacement gauge, and fix it to other measuring points, such as measuring point 1, when the basic positioning point When the length of the cable between the measuring point 1 changes, it means that the ground displacement between the basic positioning point and the measuring point 1 has changed. The reason for the change is that the ground where the measuring point 1 is located slides down. , the change can be sensed by the "pull wire displacement meter", and the data will be wirelessly transmitted to the measurement platform. But the existing technology has the following shortcomings:

① power supply problems. In order to ensure that the cable displacement meter can work for a long time and record the long-term change trend of the monitoring point position, a reliable power supply must be provided. Mains power is not feasible, because the general geological disaster monitoring points are in the wild, and there are no conditions for mains supply nearby. In addition, there is a high possibility of mains power outage, which may cause the accumulated data of bit line displacement to clear. zero. The solar power supply system is usually used to solve the power supply problem, and each monitoring point should be equipped with a set of reliable solar power supply equipment, including solar panels, storage batteries, solar power supply controllers, etc.

② Installation and construction problems. In order to ensure the work of the cable displacement sensor, in addition to ensuring the power supply, it is necessary to provide the necessary protection for the sensor to work. For example, steel poles should be used to support solar panels, equipment boxes should be used to protect electronic equipment, poles should be fixed to the ground through concrete, and cable displacement gauges should be equipped with protective casings. All of these tasks have greatly increased the difficulty of equipment installation and use.

③ data redundancy. The monitoring of the surface displacement of the geological disaster site is a long-term process, and the daily or annual change of the monitored displacement is very small. Under the conditions of the above-mentioned power supply, the frequency of data collection by the general monitoring system is very high, such as every second. Multiple pieces of data, a large amount of data is transmitted to the monitoring platform, and the data basically does not change in a short period of time, causing a lot of waste of resources to the platform.

④The implementation cost is high. The core sensor is a "pull wire displacement meter", but to make it work stably, it is additionally equipped with solar panels, storage batteries, solar power supply controllers, steel poles, protective boxes, and protective shells, and the foundation needs to be dug deep during installation. , using a concrete fixed ground cage. And these costs even far exceed the purchase cost of the cable displacement meter itself.

⑤ Anti-theft and anti-vandalism. No matter where the cable displacement monitoring device is installed, as long as it is within the range of people's activities, it may be easily damaged or stolen (storage battery). When stolen or destroyed, the user has no information and no clues for detection.

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

(1) Integrated integration, greatly reducing installation difficulty and procurement cost.

Through integrated integration, auxiliary equipment such as basic foundations, steel poles, and equipment boxes are omitted, which not only reduces the difficulty of equipment installation, but also greatly reduces the cost of procurement and installation.

(2) Integrated integration to improve equipment safety protection capabilities.

Through a shell, all the components are integrated together, which makes the protection of the equipment easier. It only needs to purchase materials with high hardness and do a good job of waterproof and dustproof, which can play the same protective effect on all equipment, circuits, etc. , and suitable for long-term use in the field.

(3) Low power consumption design, improve data usage efficiency and reduce energy consumption.

Adopting the low power consumption design concept, the MCU (Micro Control Unit) enters the sleep state regularly, and turns off the surrounding electronic components at the same time. According to the characteristics of long-term monitoring in the field, after the MCU wakes up regularly, after the data acquisition is completed, the data is first sorted to determine the amount of data change. For small changes or no changes, the number of uploads to the monitoring platform is reduced, the amount of data is reduced, and the energy consumption is greatly reduced. , but also improve the efficiency of data use.

(4) Using vibration sensor and positioning module to realize anti-sabotage and theft tracking of equipment.

The monitor has a built-in vibration sensor that records the number of vibrations. When a few vibrations occur, immediately wake up the MCU to collect and analyze the data and transmit it to the platform. When the number of vibrations reaches a certain value, for example, the number of vibrations exceeds 5 times within 1 minute, it is considered that there may be man-made damage, and an alarm message is sent to the platform. In the case of theft, the device can be tracked based on real-time location information.

(5) Unified management of a core MCU to improve operating efficiency.

Different from general equipment integration, the present invention has only one MCU, which manages sensor data acquisition, storage, and data remote transmission; coordinates power management and energy replenishment; regularly enters sleep state, and regularly wakes up by itself or externally (large vibration or angle occurs). large changes). However, in the traditional monitoring station, devices with different functions have different MCUs, each doing its own thing, and the overall efficiency is low. For example, the cable displacement sensor has an MCU, the data acquisition and transmission equipment also has its own MCU, and the solar power supply controller also has its own MCU. It is quite difficult for these MCUs to work together to achieve low power consumption. Efficiency is also low.

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

Because the surface displacement of geological disasters generally has the characteristics of long-term monitoring, that is to say, the change of displacement is very small, and long-term measurement and recording are required to calculate the quantity and rate of displacement change. In this case, the present invention can enter the sleep state regularly, and can carry out a high degree of system integration. However, for the monitoring of the surface displacement of geological disasters, when the disaster occurs, the equipment must be able to wake up in time, collect and transmit data, and issue early warning information. Therefore, the device must have an external wake-up mechanism.

The present invention has two mechanisms to realize external wake-up: one is to place four Hall sensors around the magnetic encoder, in the sleep state of the MCU, the rotation of the main shaft can be sensed, and when the rotation angle exceeds the preset angle, the MCU is woken up to enter The second is to install a photoelectric encoder on the side of the radial magnet close to the photoelectric encoder, and install the photoelectric encoder. When the spindle rotates, the photoelectric encoder wakes up the MCU to enter the normal state. The above two methods can adjust the displacement change value of the wake-up MCU according to the actual situation.

(7) Increase the flexibility of transmission mode selection through modular design.

In the design of the circuit motherboard PCB, the present invention separates the data transmission part, reserves the power supply, signal control, and data interface, and changes the data transmission mode according to actual needs by replacing the transmission module (plug-in mode). For example, NB-IOT and ZigBee with low power consumption, GPRS with wide coverage, 4G with large data transmission, WiFi with cluster transmission, etc., can meet the actual monitoring needs.

The cable measuring part is also a square shell, and in the inner center of the shell there is a main shaft (the main shaft connects the cable measuring part and other parts), a winding disc, a spring rebound mechanism, and the like. By setting the spring rebound mechanism, it can be ensured that the pull wire can be pulled out or retracted with a certain strength. Since the pull-wire measuring component is in the prior art, its structural composition will not be repeated here.

Preferably, a radial magnet 24 with a diameter of 6 mm is installed on the top end of the main shaft 23 . As the main shaft 23 rotates, the radial magnet 24 rotates at the same angle. A circuit board 6 is disposed adjacent to the radial magnets 24 , a magnetic encoder 8 is installed at the center of the circuit board 6 , and the axis center of the spindle 23 and the center of the magnetic encoder 8 are located on the same horizontal centerline.

The circuit board 7 is provided with a battery charging and discharging control circuit, a GPS positioning module, a vibration sensor, and a wireless transmission module that are electrically connected to the MCU respectively. The circuit board 7 is arranged on the side away from the radial magnet 24 , which is not on the side of the magnetic encoder 8 . The circuit board 7 also includes data acquisition and storage circuits, etc., which are managed uniformly by the MCU.

In addition, it can also be preliminarily judged according to the number of vibrations that a large inclination has occurred, or it has been damaged or moved by humans. Based on these data, the MCU will automatically enable the GPS positioning module to locate the location of the monitor in real time, providing support for inspectors to find equipment or track stolen equipment.

As shown in Figure 4, the working process of the present invention is as follows: the miniature solar panel is responsible for the power supply of the entire monitor, and is supplemented with charging under the management of the MCU; the magnetic encoder is responsible for reading the rotation angle of the radial magnet connected to the main shaft, and Converted to electrical signal for MCU use; Hall sensor can also read the rotation angle of the spindle, when the rotation angle reaches 30° or 90°, it will send a signal to the MCU to wake up the MCU in the dormant state; the photoelectric encoder (photoelectric switch) will When the spindle rotates, the pulse level is provided for the MCU through the rotation of the photoelectric encoder, which can also wake up the sleeping MCU.

By setting a main casing 1 with a mounting bracket 12, the present invention integrates multiple systems such as power supply, data acquisition, data transmission, anti-theft positioning, etc., to achieve micro power consumption, improve data use efficiency, reduce installation costs, and minimize The auxiliary cost effectively solves many shortcomings in the prior art.

First of all, due to the long-term characteristics of geological disaster displacement monitoring, the surface displacement changes slowly, or in a specific day, the displacement change is basically unchanged, so the data collection frequency does not need to be very high. In one day, the MCU is basically in a dormant state, and the surrounding circuits are basically in a power-off state when the MCU is dormant, saving more power. Within a day, the MCU automatically wakes up several times at regular intervals, collects displacement data, and compares and analyzes data changes. When the data does not change, it regularly transmits data to the remote platform once or several times a day. Only when the displacement data changes greatly, the frequency of uploading data is automatically increased, and an early warning signal (specific data of 0 or 1) is issued. This design improves data usage efficiency while reducing energy consumption by using the sleep mechanism.

Second, integrated power supply is possible due to the enabled sleep mechanism. The invention uses multiple groups of lithium batteries to form a storage battery, and a maximum 20000mA battery group can be configured as required. In order to meet the requirements of large data transmission and long-term use, an external micro solar panel is integrated, and the power supply system is highly integrated through the battery charge and discharge control circuit integrated on the circuit board. Allows the monitor to theoretically be used indefinitely.

Thirdly, the present invention is an independent device with a mounting bracket at the bottom from the outside, so it can be easily fixed and installed, and then the pull wire is pulled out and fixed to the position of the monitoring point, and it can work normally when it is powered on, no other The auxiliary infrastructure work can greatly reduce the installation difficulty and installation cost.

At the same time, the vibration frequency and number of times are collected by the vibration sensor. When vibration occurs, not only can the MCU be woken up, but when the number of vibrations reaches a certain threshold, the positioning module will be activated and an alarm signal will be sent to the platform. Remind the inspectors to check the situation of the monitor in time and track the monitor according to the positioning information. Through the built-in vibration sensor and GPS positioning module, the monitor has certain anti-theft, anti-sabotage, positioning and tracking capabilities.

Finally, the one-piece shell has strong waterproof ability. In the design of the casing, taking into account the need for outdoor waterproofing, waterproof measures have been added to key parts, which can achieve IP67 or higher waterproof and dustproof capabilities, and meet long-term outdoor use in the wild.

The invention converts the displacement of the pull wire into the change of the angle through the pull wire measuring component, then measures the change of the angle through the magnetic encoder and outputs it in the form of an electrical signal, and then controls the timing sleep and wake-up equipment through the MCU; by comparing the collected data Judgment, control the frequency of data uploading by the wireless transmission module according to the data change range; carry out energy management, when the sun is full, the battery can be replenished; by using Hall sensors or photoelectric switches, real-time monitoring of the rotation of the spindle to achieve external wake-up; through the integration of settings It can realize equipment protection, waterproof and dustproof; by setting its own mounting bracket, it is convenient for installation and construction; through the linkage of vibration sensor and GPS positioning module, it can realize damage alarm and equipment tracking.

The invention has the characteristics of simple production and processing, low processing cost, low power consumption and the like. In some special occasions, the input of external power supply facilities can be reduced through the low power consumption mode, and the same monitoring efficiency can be achieved with a lower input, which greatly reduces the cost and saves energy and reduces consumption.

The above-mentioned embodiments are not intended to limit the present invention, and the present invention is not limited to the above-mentioned examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the technical solutions of the present invention also belong to the present invention. the scope of protection of the invention.
