Description

Building health management method, system, storage medium and monitoring system

Technical Field

The invention belongs to the field of disaster monitoring, and particularly relates to a building health management method, a building health management system, a building health management storage medium and a building health monitoring system.

Background

With the development of economy and technology, more and more buildings are built in cities, and therefore, more and more safety problems related to the buildings also appear. For example: some buildings may have problems such as building inclination and settlement due to construction problems, geological problems, or other nonreactive factors. Once the problems occur in the building, the house is easy to collapse, property damage is caused, and in the serious condition, serious casualty accidents can occur.

At present, devices for monitoring the inclination and the settlement of a building body are released in the market, but the detection of the inclination of the building body is mainly realized by directly detecting through an inclination angle sensor, and the detection of the settlement is mainly realized through a ground penetrating radar. When the tilt sensor directly detects, a matched signal acquisition device and a controller unit are also required to be arranged for the tilt sensor, if the matched devices are not configured, only wired signal transmission can be carried out, so that wiring is complex and cost is increased, especially, the problems can be shown when the tilt sensor is applied in large scale and regionalization, and when the tilt sensor is relied on for detection, if the tilt sensor breaks down, the conditions of no alarm or false alarm and the like can be caused to occur due to inaccurate detection, and the system can not complete self-check, so that the condition of building inclination is lost. When the ground penetrating radar is used for settlement detection, the settlement detection can be completed without changing the position and the posture of the ground penetrating radar continuously, and if a large amount of ground penetrating radars are used for synchronous detection, the cost of manual adjustment can be reduced, but the whole hardware is greatly improved, and particularly when the ground penetrating radar is applied regionally, the cost is increased. Therefore, the purpose of continuously monitoring the regional house is difficult to meet by common monitoring products on the market at present.

A building health management method according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 7. The building health management method comprises the following steps:

the method comprises the steps that a plurality of distance measurement data are obtained, each distance measurement data is obtained by measuring one building body monitoring group, the number of the building body monitoring groups is multiple, each building body monitoring group at least comprises four building body monitoring devices, the building body monitoring groups jointly comprise N building body monitoring devices, and the N building body monitoring devices are correspondingly arranged at the tops of N buildings to be monitored in an area to be monitored one by one; wherein, each building monitoring device is used for sending and receiving distance measurement wireless signals; each building monitoring device is provided with a satellite positioning module 140, and the satellite positioning module 140 is used for completing time synchronization by using a satellite navigation system;

acquiring a plurality of groups of stress monitoring data, wherein each group of stress monitoring data is measured by a group of stress detection units; the stress detection units are provided with N groups, the N groups of stress detection units correspond to N buildings to be monitored one by one, each group of stress detection units comprises a plurality of stress detection units, and the stress detection units are arranged at different positions corresponding to the buildings to be monitored; each building body monitoring device and each stress detection unit are communicated with a server through a wireless network to perform data interaction;

and determining the building health state of each building to be monitored according to the ranging data and the stress monitoring data, wherein the building health state at least comprises a building inclination state, a building settlement state and a building crack state.

Referring to fig. 1 to 7, treat that there is a N building that needs to monitor in the detection region, and the corresponding N building body monitoring devices that has arranged, a serial number that N building body monitoring devices can correspond, and guarantee the uniqueness of every serial number, and divide a plurality of building body monitoring devices into for a plurality of building body monitoring groups, every building body monitoring group through the inside distance detection between the building body monitoring devices between alright accomplish with the definite to building body slope, settlement state.

When any building monitoring group carries out distance measurement, the distance measurement data of each building monitoring device can be determined in sequence according to the serial number sequence. The building monitoring devices can receive and transmit ranging wireless signals, in each ranging process, the building monitoring devices needing to finish ranging data determination are switched to a signal receiving state, other building monitoring devices in the group are switched to a signal transmitting state, other building monitoring devices in the group can sequentially transmit ranging wireless signals to the building monitoring devices in the signal receiving state according to the numbering sequence, sufficient intervals need to be kept in the transmission process of the ranging wireless data twice, the phenomenon that the signals overlap time to cause ranging errors is avoided, meanwhile, sufficient time intervals exist, and the server can also finish the determination of the transmission time by directly utilizing the signal receiving time and the signal transmitting time; meanwhile, when other building monitoring devices of the group send distance measurement wireless signals, the sending time information and the corresponding numbers are synchronously sent to the server.

After the server determines the sending time of each building monitoring device in the sending state and the receiving time of each building monitoring device in the receiving state, the server can determine the spatial distance relationship between the two building monitoring devices, the spatial distance relationship measured by the building monitoring devices in the group and the spatial coordinate of each building monitoring device can be utilized to determine the spatial coordinate to be measured of the building monitoring device in the receiving state in the distance measurement, and the spatial coordinate to be measured and the initial spatial coordinate of the building are compared, so that whether the building is inclined or settled can be rapidly determined.

It should be noted that, in order to ensure the accuracy of ranging, the satellite positioning module 140 may be built in the building monitoring device, and the satellite positioning module 140 is used to complete time synchronization, which may better ensure the accuracy of time compared to a method of directly using a system clock or using a network to perform time synchronization. Meanwhile, the satellite positioning module 140 can also be used for directly acquiring the spatial coordinates of the building monitoring device, and under the condition that the building monitoring device is fixedly installed, the spatial coordinates of the building monitoring device can be directly used for determining the inclination and settlement states of the building, so that a double-determination system can be formed by using the communication between the building monitoring device and the measuring mode, and the monitoring accuracy is further ensured. However, when the satellite positioning mode is used, the satellite positioning mode is easily affected by the environment, particularly when the weather environment is poor, the satellite signal is weak, and the detection is easy to be inaccurate, so that in the environment, the service can be selected autonomously, and the mode that the positioning module directly determines the state of the building body is abandoned.

In addition, in order to accomplish the detection to building body stress, can all set up a plurality of stress detecting element in every building body, stress detecting element can direct detection wall body and load-carrying members's stress change, when the crack appears, can continuously appear the irreversible change process of stress at the region that appears the crack at least, utilizes this kind of change, whether can direct effectual definite crack appears. When the stress monitoring device is used in a community, if an owner changes the bearing structure privately, the stress monitoring device can be quickly detected by the stress monitoring unit, so that the dangerous case is avoided. It should be noted that, in order to simplify the difficulty of arranging the stress detection unit, the stress detection unit is designed to be a passive wireless design, and a low power consumption design is adopted, so as to effectively increase the cruising ability of the stress detection unit. Stress monitoring data detected by the stress detection unit can be directly and wirelessly transmitted to the server through the Internet or the local area network, and each stress detection unit can be provided with a unique serial number, so that the server can accurately analyze the stress monitoring data. Specifically, when data transmission is performed, two bytes in the data can be marked as a sensor type, the two bytes can be marked as a number, and the stress monitoring data or the sending time information which can be followed after the number marking can be sent.

According to the building health management method provided by the embodiment of the invention, building body monitoring devices are arranged on the top of the building to be monitored in the area to be monitored, and the building to be monitored is divided into monitoring groups, so that distance measurement signals can be transmitted and received mutually in the groups, the distance spatial distance detection is completed, and on the premise that at least four building body monitoring devices in the groups are ensured, whether the building to be monitored in a receiving state is inclined or settled can be determined through constraint; meanwhile, in order to ensure the time synchronization, the built-in satellite positioning module 140 can be used to complete the high-precision time synchronization, thereby further ensuring the accuracy of distance measurement. In addition, by arranging a group of stress detection units in each building to be monitored, effective detection of cracks can be completed. The building health management method provided by the embodiment of the invention is constructed based on a wireless communication mode, effectively reduces the arrangement of power lines, reduces the cost and the arrangement construction difficulty, can directly finish the judgment of inclination and settlement by utilizing a mode of sending distance measurement signals between buildings, does not need to arrange an inclination angle sensor and a bottom detecting radar any more, effectively controls the cost, and is suitable for industrial and large-scale popularization.

In some embodiments of the invention, multiple building monitoring groups sequentially perform ranging;

the ranging data is obtained by the following steps:

each building monitoring device sequentially receives ranging wireless signals sent by the rest building monitoring devices in the building monitoring group; the time interval between any two adjacent transmitted ranging wireless signals in the building monitoring group exceeds the preset measurement interval time;

when each building monitoring device sends a ranging wireless signal, packaging the corresponding serial number and sending time information when the ranging wireless signal is sent into a ranging data packet, and transmitting the ranging data packet to a server;

when each building monitoring device sequentially receives ranging wireless signals sent by the rest building monitoring devices in the corresponding building monitoring group, recording receiving time information received each time and transmitting the receiving time information to a server;

and generating ranging data according to the ranging data packet sent by the building monitoring group and the receiving time information.

Referring to fig. 5 and 6, considering that the inclination and settlement of a house cannot cause serious consequences in a very short time, when actual detection is performed, distance measurement can be performed on a plurality of building monitoring groups in sequence, so that power consumption caused by frequent distance measurement can be reduced, and signal interference caused by distance measurement performed by a plurality of building monitoring groups can be avoided. Meanwhile, when each building monitoring group carries out distance measurement, distance measurement is carried out on each building monitoring device inside one by one, namely in the group, only one building monitoring device is in a receiving state each time, and the rest building monitoring devices are in a sending state, namely in a house at the middle position shown in 5. Moreover, when ranging is performed, enough measurement interval time is ensured when ranging wireless signals are transmitted twice, so as to avoid signal transmission errors, for example: referring to fig. 5 and 6, one building monitoring group includes four building monitoring devices numbered from 1 to 4, and when the distance measurement is performed on the building at the middle position shown in fig. 5 of the building monitoring device No. 1 and in the hollow circle in fig. 6, the building monitoring devices No. 2, 3 and 4 sequentially transmit distance measurement wireless signals to the building monitoring device No. 1, and a sufficient interval is maintained therebetween, for example, the measurement interval time is 10 seconds, it should be noted that the time interval between the two building monitoring groups may be longer, for example, 30 seconds.

On the basis of the above setting, only one building monitoring device sends a distance measurement wireless signal in each time period, so after the building monitoring device sends the distance measurement wireless signal, only the corresponding number and the sending time information need to be sent to the server, and meanwhile, after the building monitoring device in a receiving state receives the distance measurement wireless signal, only the receiving time information needs to be sent to the server. After the server receives the ranging data packet, the server can analyze the number to determine a building monitoring group for ranging at the current stage, analyze the sending time information at the same time, and determine the signal transmission duration according to the sending time information and the receiving time information received in the same time period, thereby determining the distance between the sending time information and the receiving time information by using the duration and the electromagnetic wave transmission speed. Still taking four building monitoring devices numbered 1 to 4 and 10 seconds between two signal transmission as an example, after the building monitoring device numbered 2 transmits a ranging wireless signal, the server packages and transmits the number and the transmission time information, meanwhile, the No. 1 building monitoring device receives the ranging wireless signal and records the receiving time information, and transmits the received time information to the server, the server only receives the two time information in the working time period of 10 seconds, so that the time interval for sending and receiving the ranging wireless signal can be directly determined according to the time sequence, and the first ranging length can be determined, after the 10-second testing time period passes, the No. 2 building body monitoring device takes over to measure the distance, when 3 times of distance measurement is completed, three distance measurement lengths can be utilized to assist in determining whether the No. 1 building body monitoring device is inclined or settled.

In some embodiments of the present invention, generating ranging data according to the ranging data packet sent by the building monitoring group and the receiving time information comprises the following steps:

determining a building monitoring group currently carrying out distance measurement according to the plurality of serial numbers and a preset distance measurement group division table, wherein the distance measurement group division table comprises a plurality of group serial number information, the plurality of group serial number information is in one-to-one correspondence with the plurality of building monitoring groups, and each group of group serial number information comprises a plurality of serial numbers in one-to-one correspondence with the plurality of building monitoring devices in the corresponding building monitoring group;

determining a building body monitoring device in a receiving state at present based on a ranging group division table, and sequentially determining receiving time information corresponding to each sending time information;

determining a plurality of distance measurement lengths according to the sending time information of each building body monitoring device in the sending state and the receiving time information of each building body monitoring device in the receiving state, and generating distance measurement data according to the plurality of distance measurement lengths, wherein the plurality of distance measurement lengths correspond to the numbers of the plurality of building body monitoring devices in the sending state one to one.

Referring to fig. 5 and 6, in order to simplify the size of the transmission data when actually performing ranging, the ranging packet only needs to transmit the sending time information and the number information. The server is internally provided with a distance measurement group division table which contains all divided building monitoring group information and the number of each building monitoring device in each building monitoring group. When ranging is started every time, as long as the serial number in the ranging data packet is determined to be received, the building body monitoring group which is used for ranging currently can be rapidly determined by comparing the serial number with the ranging group division table, so that the initial space coordinates of all building body monitoring devices in the building body monitoring group can be obtained in advance, after the ranging length is determined for multiple times, the inclined state and the settlement state of the building body can be rapidly determined, and it needs to be explained that in order to avoid the recording error of the ranging length, when the ranging length is recorded, the one-to-one corresponding relation with the corresponding serial number can be established.

In some embodiments of the invention, a spatial coordinate system is constructed, and initial spatial coordinates corresponding to each building monitoring device are determined in the spatial coordinate system; a plurality of building body monitoring devices in each building body monitoring group sequentially complete corresponding distance measurement data determination;

after the server acquires the ranging data each time, the building body inclination state and the building body settlement state of the building body monitoring device in the receiving state are determined by the following steps:

determining the space coordinate to be measured of the building body monitoring device in a receiving state in the building body monitoring group according to the initial space coordinate of the building body monitoring device in a transmitting state in the building body monitoring group and the corresponding distance measurement data;

Referring to fig. 5 and 6, a three-dimensional space coordinate system is directly constructed for the area to be monitored, so that all building monitoring devices in the area have a corresponding initial space coordinate. Therefore, the building monitoring device needing to be monitored also has one, and meanwhile, after the building monitoring device is subjected to ranging, a corresponding space coordinate to be measured can be obtained, and the inclination and settlement state of the building needing to be monitored can be determined by utilizing the two coordinates.

Still taking four building monitoring devices numbered 1 to 4 as an example, building monitoring is explained, and for the sake of simplifying the description, only the determination of the inclination and settlement state of the building monitoring device No. 1 will be described here. After the distance measurement of the No. 1 building is completed, 3 distance measurement lengths can be obtained, the 3 distance measurement lengths correspond to 3 building monitoring devices, the initial space coordinates corresponding to the three building monitoring devices can be used for determining 3 corresponding spherical surface constraint relations, the common point of the 3 spherical surfaces is further solved, and the space coordinate to be measured (x) of the No. 1 building monitoring device can be determined (x)₁，y₁，z₁) And the No. 1 building body monitoring device can directly determine the initial space coordinate (x) after being arranged₀，y₀，z₀). With further reference to fig. 5, 6, if a tilt occurs, a shift towards x and/or y occurs, resulting in a difference, and if a dip occurs, a shift in the z direction occurs, resulting in a difference. Of course, the difference in z direction caused by the inclination needs to be further considered when the detection is actually performed to further determine whether only the settlement occurs or both the settlement and, in the actual situation, both the settlement occurs at the same time, for example, the settlement occurs at one side of the building body, thereby causing the inclination to occur.

In some embodiments of the present invention, in order to ensure the accuracy of distance measurement, each building monitoring group includes at least 5 building monitoring devices or more, so as to ensure the accuracy of monitoring. For example, there are No. 1 to No. 5 building monitoring devices, and when No. 1 is measured, four measurement lengths are obtained, and then the four measurement lengths are used to constrain the spatial coordinates to be measured of No. 1. Specifically, one spatial coordinate to be measured is constrained by any 3 ranging lengths, 4 spatial coordinates to be measured can be obtained after traversing all the conditions, and the most accurate spatial coordinate information can be obtained by averaging the 4 spatial coordinates and other operations.

In some embodiments of the invention, when a certain building monitoring device fails, building monitoring devices in an adjacent building monitoring group are temporarily added to complete monitoring of the building monitoring devices in the group, and meanwhile, after ranging data is lost for a long time, a server gives an alarm and notifies maintenance personnel to maintain. It should be noted that the building monitoring groups in the embodiment of the present invention do not need to be completely unrelated to each other, and one building monitoring device may be divided into a plurality of building monitoring groups, which may further increase the monitoring stability of the whole system, but may result in a longer monitoring period.
