[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0053] The present invention provides a building monitoring management method and system, which solves the technical problems in the background technology.

[0054] In the embodiment of the present invention, the monitoring equipment includes a first monitoring equipment and a second monitoring equipment, wherein the two can be the same monitoring equipment or different monitoring equipment, and are mainly used for deformation monitoring of buildings, including one or more of strain monitoring, horizontal displacement monitoring, vertical displacement monitoring, tilt monitoring, crack and structural seam monitoring and surface strain monitoring. For example, strain monitoring can use strain monitoring elements such as resistance strain gauges, vibrating string strain gauges, and optical fiber strain gauges, crack monitoring can use electronic crack observers, acceleration sensors, pressure sensors, etc., special wind pressure gauges can be used to measure wind pressure, wind speed, etc., and tilt measurement can use inclination sensors, levels, etc., so the monitoring equipment in the present invention includes one or more of the above sensors or electronic components, which can be selected according to actual needs in practice.

[0055] like Figure 1 FIG. 1 is a main flow chart of a building monitoring management method provided by an embodiment of the present invention, wherein the building monitoring management method comprises:

[0056] Step S10: If it is determined that the first monitoring device has an abnormality, determine whether the second monitoring device that has a linkage relationship with the first monitoring device has an abnormality, wherein the linkage relationship is used to indicate that the first monitoring device and the second monitoring device maintain a communication connection under normal conditions, and the first monitoring device sends an emergency message to the second monitoring device when a position abnormality occurs;

[0057] Specifically, the monitoring device is used to monitor the deformation of the building. When it is determined that the first monitoring device is abnormal, it is determined whether the first monitoring device is also abnormal. There is a chain relationship between the first monitoring device and the second monitoring device, that is, when both are normal, that is, in the default normal state, the two maintain a communication state, and in the preset program setting, the first monitoring device detects the change of its own position. When it is detected that it is separated from a certain installation position of the building, the first monitoring device sends an emergency message to the second monitoring device (equivalent to starting an emergency setting program). This emergency message is a "signal" mark in a specific state; judging whether the first monitoring device and the second monitoring device are abnormal, for example, it can be determined by whether the self-test of the two is normal. When the self-test is normal, the two can report a state signal of normal self-test. If no state signal of normal self-test is reported, it is considered that there is an abnormality. Of course, other methods can be used, and the specific details can be referred to the subsequent embodiments. Maintaining a communication connection in a normal state (at this time, it can be considered that the position of the first monitoring device is not abnormal) can be used for the purpose of: the second monitoring device aggregates the monitoring information of multiple first monitoring devices and detects the monitoring information to determine the deformation of the building, such as whether the cracking of the wall is aggravated, and whether the inclination of a certain position exceeds the maximum allowable inclination angle.

[0058] Step S11: if the second monitoring device does not have an abnormality, obtain the emergency information sent by the first monitoring device when an abnormality occurs in the position and stored in the second monitoring device, wherein the emergency information includes updated monitoring information of the building and location change information of the first monitoring device;

[0059] Specifically, when the second monitoring device does not have an abnormality and the first monitoring device has an abnormality, the second monitoring device stores emergency information, wherein the updated monitoring information is the latest monitoring information sent by the first monitoring device before the abnormality occurs, and the position change information is the position change of the first monitoring device from leaving the installation position to before sending the emergency information. It should be noted that the position change information can be the position change starting from the detection of its own movement and meeting the preset time length. The position change can be determined by the built-in positioning unit, and can also be identified by identifying the real-time image near the installation position (such as setting a line mark near the installation position, and different line marks represent different positions);

[0060] Step S12: Detecting the state of the building and the first abnormal condition of the first monitoring device according to the emergency information;

[0061] Specifically, when there is no abnormality in the second monitoring device and the first monitoring device is abnormal, the state of the building is determined with the help of the updated monitoring information in the emergency information, and the condition of the first monitoring device is determined with the help of the position change information. For example, if it deviates from the installation position by more than a preset distance, there may be a risk of loss, which may be caused by human factors. If it is always close (not exceeding the preset distance), it may fall off naturally. Therefore, the first abnormal state can be determined.

[0062] Step S13: if the second monitoring device is abnormal, determine a first monitoring device that covers the monitoring device, the monitoring device includes a first monitoring device and a second monitoring device;

[0063] Specifically, in another situation, the second monitoring device is abnormal, that is, both the first monitoring device and the second monitoring device are abnormal. At this time, according to the setting, the first monitoring device covers the first monitoring device and the second monitoring device. There can be multiple first monitoring devices. According to the actual position of the monitoring device, the first monitoring device covering the monitoring device can be determined.

[0064] Step S14: Detecting a second abnormal condition of the first monitoring device and the second monitoring device according to the monitoring information of the first monitoring device.

[0065] Specifically, the monitoring information of the first monitoring device can be used to determine the second abnormal condition of the first monitoring device and the second monitoring device. Since both the first monitoring device and the second monitoring device are abnormal, the second abnormal condition can be determined through the monitoring information of at least one of the first monitoring devices when they are working. For example, the monitoring device becomes abnormal after a suspicious target (such as a person) comes into contact with the monitoring device. This can be achieved by tracing at least one of the monitoring device and the suspicious target with the help of relevant monitoring information. If no suspicious target appears, the staff can be notified to conduct a comprehensive inspection of the installation area and the monitoring equipment.

[0066] When this embodiment is applied, if it is determined that an abnormality has occurred in the first monitoring device, it is determined whether an abnormality has occurred in the second monitoring device that has a linkage relationship with the first monitoring device. The linkage relationship is used to indicate that the first monitoring device and the second monitoring device maintain a communication connection under normal conditions. Under this communication connection, it can be achieved that the monitoring information of several or even multiple first monitoring devices are transmitted through the corresponding second monitoring devices, and when a position abnormality occurs, the first monitoring device sends an emergency message to the second monitoring device, and the emergency message includes the updated monitoring information of the building and the position change information of the first monitoring device. If the second monitoring device does not have an abnormality, the emergency message sent by the first monitoring device when the position abnormality occurs and stored in the second monitoring device is obtained, and the state of the building and the first abnormal condition of the first monitoring device are detected according to the emergency information. Even if the first monitoring device is abnormal, the emergency information including the updated monitoring information and the position change information can be obtained through the second monitoring device to determine the state of the building and the first abnormal condition of the first monitoring device. If the When an abnormality occurs in the second monitoring device, a first monitoring device covering the monitoring device is determined, and the monitoring device includes a first monitoring device and a second monitoring device; the second abnormal condition of the first monitoring device and the second monitoring device is detected according to the monitoring information of the first monitoring device. In this case, actual maintenance can be performed according to the actual abnormal type of the first monitoring device and the second monitoring device to ensure that the monitoring of the building is restored as soon as possible. The above can realize that the first monitoring device and the second monitoring device can realize the transmission of monitoring information in a normal state according to the data update requirements when they are communicating normally. By obtaining emergency information, even if the first monitoring device of the building is abnormal, it is ensured that the latest monitoring information can still be obtained. When both the first monitoring device and the second monitoring are abnormal, effective maintenance can be performed according to the actual abnormal type of the first monitoring device and the second monitoring device. The abnormal situations in both cases (the state of the building, the first abnormal condition and the second abnormal condition) can provide reliable judgment for the operation and maintenance personnel on the rapid operation and maintenance of the monitoring equipment, thereby facilitating the rapid monitoring and recovery of the building and improving the safety of building monitoring.

[0067] like Figure 2 As shown, as an optional embodiment of the present invention, if it is determined that the first monitoring device has an abnormality, determining whether the second monitoring device that has a chain relationship with the first monitoring device has an abnormality includes:

[0068] Step S101: obtaining a monitoring result transmitted back by a second monitoring device, wherein the monitoring result includes a determination result determined by the second monitoring device according to first monitoring information transmitted by the first monitoring device;

[0069] Specifically, after the first monitoring device transmits the first monitoring information to the second monitoring device according to (a certain transmission rule, such as irregular), the second monitoring device performs a judgment function to judge the first monitoring information, such as judging the speed of change of a certain deformation value in the first monitoring information, or whether it exceeds a certain preset warning threshold, and then obtains a judgment result. At the same time, the second monitoring device itself can also perform a monitoring function and perform related deformation judgments (such as the speed of change of another deformation value, or whether it exceeds another preset warning threshold, etc.).

[0070] Step S102: if the monitoring result shows that the judgment source is lost, obtain identification summary information of the monitoring device, wherein the judgment source includes the first monitoring information, and the identification summary information is associated with the first monitoring information and is independent of the second monitoring device;

[0071] Specifically, the judgment source includes the first monitoring information. When the judgment source is lost, it at least indicates that the first monitoring device has not sent the first monitoring information to the second monitoring device, and obtains the identification summary information. The identification summary information is independent of the monitoring result, indicating that the identification of the monitoring device is not related to the second monitoring device when it is sent out, but is related to the first monitoring information. Therefore, relevant judgments can be made based on the two. For detailed description, please refer to the subsequent statements.

[0072] Step S103: Determine whether the first monitoring device and the second monitoring device are abnormal according to the identification summary information and the determination result actually included in the monitoring result.

[0073] Specifically, since the identification summary information is associated with the first monitoring information and is independent of the second monitoring device, when the first monitoring device sends the first monitoring information to the second monitoring device, it is accompanied by a summary including the identification of the first monitoring device, and this summary is independent of the second monitoring device. If the first monitoring device is normal and the second monitoring device is abnormal, the identification summary information should include the identification of the first monitoring device. If both are abnormal, the identification summary information does not include the identification of the first monitoring device, and should not include the second monitoring device's judgment result on the first monitoring information of the first monitoring device. If the first monitoring device is abnormal and the second monitoring device is normal, the monitoring result may include the judgment result of the monitoring information of other first monitoring devices. Therefore, through this relationship, it can be used to determine whether the first monitoring device and the second monitoring device are abnormal.

[0074] It can be understood that by combining the determination result and the identification summary information, it is possible to quickly determine whether the first monitoring device and the second monitoring device are normal or not, thereby providing a maintenance basis for the abnormal monitoring device.

[0075] In combination with the above embodiment, optionally, determining whether the first monitoring device and the second monitoring device are abnormal according to the summary information and the determination result actually included in the monitoring result includes:

[0076] Step: determine whether the first identification of the first monitoring device in the identification summary information is missing;

[0077] Specifically, to determine whether the first identifier is missing, it is only necessary to traverse the identifiers in the identifier summary information. If the first identifier is not detected, it is considered that the first identifier is missing. Otherwise, it can be considered that the first identifier is not missing.

[0078] Step: If so, it is determined that an abnormality has occurred in the first monitoring device, and if the monitoring result actually includes part of the determination result, it is determined that no abnormality has occurred in the second monitoring device, or, if the monitoring result actually does not include any of the determination results, it is determined that an abnormality has occurred in the second monitoring device.

[0079] Specifically, when the first identifier is missing, it indicates that there is an abnormality in the first monitoring device (always ensuring that the non-second monitoring device is normal), the first monitoring device has not transmitted the updated monitoring information of the building to the second monitoring device, and the second monitoring device also fails to make this judgment. If only part of the judgment results exists, it is considered that other first monitoring devices have sent updated monitoring information to the second monitoring device, and the second monitoring device has made a judgment on this. At this time, it can be considered that the second monitoring device has not functioned normally. Of course, on the contrary, if the monitoring result does not actually include any of the judgment results, it is considered that the second monitoring device has not made any judgment. In the pre-setting, there are multiple first monitoring devices that transmit updated monitoring information to the second monitoring device.

[0080] The identification summary information is transmitted back by multiple non-second monitoring devices after the first monitoring device sends the first monitoring information to the second monitoring device according to a preset rule each time.

[0081] That is, each time the first monitoring device sends the first monitoring information to the second monitoring device, an identification will be sent back through the non-second monitoring device. The non-second monitoring device is a plurality of specially set transfer devices, and the transfer device is used to send back the identification information. The preset rules include according to the preset period, and can also be irregular. In practice, it can be set according to actual needs.

[0082] Therefore, when there is no missing, it indicates that the first monitoring device sends the first monitoring information and sends the identification through a non-second monitoring device.

[0083] In summary, the above steps can be used to verify whether an abnormality occurs in the first monitoring device or the second monitoring device, and relatively reliably detect the normality of the first monitoring device and the second monitoring device that have a coordinated relationship, laying the foundation for detecting the first abnormal condition and the second abnormal condition.

[0084] like Figure 3 As shown, as an optional embodiment of the present invention, detecting the state of the building and the first abnormal condition of the first monitoring device according to the emergency information includes:

[0085] Step S121: determining the deformation status of the building according to the updated monitoring information;

[0086] Specifically, the monitoring information is continuously updated, and the deformation status can be judged based on the updated monitoring information, such as the continuous enlargement of cracks in the building, the continuous change of inclination, etc. Each single deformation parameter in the updated monitoring information is compared with the standard deformation level parameter to determine the deformation status.

[0087] Step S122: determining whether the deformation condition reaches a preset warning level;

[0088] Specifically, when the deformation condition reaches the standard deformation level parameter corresponding to the preset warning level, the deformation condition is determined to have reached the preset warning level. If the deformation condition does not reach the standard deformation level parameter corresponding to the preset warning level, the deformation condition is determined to have not reached the preset warning level. For example, there are three standard deformation level parameters for cracks in buildings, namely 0.2mm, 0.2-1mm, and greater than 1mm. When the structural cracks reach 0.2mm, the degree of the structural cracks is considered to be medium, which may have a certain impact on the safety and stability of the building. As for those greater than 1mm, they are directly considered to have reached the serious level. In practice, when the degree of the structural cracks reaches medium, that is, when the standard deformation level parameter reaches 0.2mm, the deformation condition is considered to have reached the preset warning level.

[0089] Step S123: if not, determining the deformation advance warning time of the building based on the stored updated deformation record and the deformation condition;

[0090] Specifically, each time the deformation data of the building is recorded by monitoring equipment and manual reporting, and stored to obtain an updated deformation record. The updated deformation record is the correspondence between time and deformation value. Based on the correspondence and the final deformation condition, the first method is: divide it into N sub-correspondences (the ratio of the total time length to the time length) according to a single time length, and detect the first change derivative of each sub-correspondence. Based on the final deformation condition, calculate the second change derivative, determine the first change derivative and the corresponding deformation segment that are within a preset deviation range from the second change derivative, and determine the history of the deformation segment from the deformation value that meets the final deformation condition to the set value. The number of elapsed time and the number of corresponding deformation segments is the number of elapsed time. The average value of all elapsed time is taken to obtain the deformation advance warning time, where the set value is less than the minimum parameter of the deformation warning, and the threshold parameter corresponding to a certain warning level is a, then the set value is b (b is less than a, b can be 0.8a). Since the updated deformation record is the deformation situation of the same or closer position in the recent period, it has a certain reference value for early warning. The second type of method is to establish a deformation prediction model based on the updated deformation record, such as the building prediction model based on CNN and the structural deformation prediction model based on Bi-LSTM, and substitute the deformation condition and the set value to determine the deformation advance warning time of the building.

[0091] Based on the obtained advance warning time, a prediction can be made in advance when the first monitoring device is abnormal, so as to ensure that the first monitoring device is maintained at least before the advance warning time and the building is further monitored and maintained, thereby ensuring the safety of the building.

[0092] Step S124: If yes, directly issue a deformation warning.

[0093] Specifically, the deformation warning can be directly initiated based on the first monitoring device and the central control terminal of the central control room, such as in the form of a screen pop-up window or in the form of an alarm ringing, so that relevant personnel can deal with the deformation situation in time.

[0094] When this embodiment is applied, it determines the latest deformation status and then determines whether the deformation status reaches the preset warning level. If it reaches the level, a warning can be directly issued. If it does not reach the level, the deformation advance warning time can be predicted, thereby achieving the effect of early warning.

[0095] As an optional embodiment of the present invention, the detecting the state of the building and the first abnormal condition of the first monitoring device according to the emergency information further includes:

[0096] Step: judging whether the first monitoring device leaves the first preset area where the first monitoring device is installed according to the position change information;

[0097] Specifically, the monitoring device has its own installation area, which can be the installation location of the monitoring device on the building. The first preset area is an area demarcated with the installation area as the center. When the position of the first monitoring device changes, it is determined whether the first monitoring device has left the first preset area. When the first monitoring device is identified outside the first preset area, it is determined that the first monitoring device has left. If the first monitoring device is always detected to be in the first preset area, it is considered that the first monitoring device is in the first preset area. After leaving the installation area, the monitoring device starts its own positioning function within the preset time length, and continuously transmits the location signal to the outside. The change of the location signal within the preset time length can be considered as the location change information.

[0098] Step: If yes, determine that the first monitoring device is at risk of being lost.

[0099] If the vehicle has not left the first preset area, it indicates that it has left the installation area, but is still near the installation area, and a prompt should be given to promptly check and restore the vehicle to its original position.

[0100] Specifically, this situation corresponds to the situation where the above result is yes. At this time, the first monitoring device may leave the first preset installation area due to certain factors (such as human factors or natural factors), and naturally leave the installation area. This situation is deemed to be at risk of loss (out of control).

[0101] It can be understood that by combining the judgment of the position change information, it is possible to determine whether the first monitoring device is at risk of being lost. In the case where there is a risk of loss, there is no abnormality in the corresponding second monitoring device. At this time, in combination with the risk of loss of the first monitoring device, the first monitoring device can be inspected separately, such as starting a patrol robot to conduct a comprehensive inspection of the first monitoring device and even other monitoring devices.

[0102] As an optional embodiment of the present invention, it also includes:

[0103] Step: determining the moving direction of the first monitoring device according to the position change information, and generating first tracking warning information according to the moving direction;

[0104] Specifically, according to the change of the position at at least two moments in the position change information, the two constitute a position vector from the initial moment position to the final moment position, and the direction of the position vector is also the moving direction. The warning information containing the moving direction is the first tracking warning information.

[0105] Step: sending the first tracking warning information to the central control terminal and determining whether the moving direction is directionally associated with the second monitoring device;

[0106] Specifically, the first tracking warning information is first sent to the central control end, which is equivalent to the control center, so that relevant personnel can make decisions based on the first tracking warning information; in addition, it is also determined whether there is a directional association: when the second monitoring device is within the preset orientation deviation range of the moving orientation (taking the initial moment position as the initial starting point, determining the orientation deviation between the first orientation of the initial moment position and the position of the second monitoring device and the moving orientation), if so, it is considered that there is an association, otherwise, it is considered that there is no directional association. For example, if the preset orientation deviation range is set to 20°, and the orientation deviation between the connecting line and the moving orientation is 18°, it is considered that there is a directional association.

[0107] Step: If yes, generate second tracking warning information according to the first tracking warning information and the identifier of the central control terminal, and send the second tracking warning information to the second monitoring device, so that the second monitoring device receives the tracking signal sent by the central control terminal and responds.

[0108] When there is no direction association, prompt information can be directly reported to indicate the deviation between the moving direction and the preset direction of the second monitoring device.

[0109] Specifically, a second tracking warning information is generated and sent to the second monitoring device. After cooperating with the first tracking warning information, the central control terminal updates the position as the relevant personnel move, and sends the position information to the second monitoring device. When receiving the position information, the second monitoring device first reads the identifier, and when it is determined that the identifier is consistent with the identifier stored in the central control terminal, it receives the tracking signal including the position information. When it is determined that the second monitoring device is within a preset distance range from the central control terminal, it emits an acoustic and optical signal, and the central control terminal synchronously emits the acoustic and optical signal to prompt the relevant personnel to pay attention to the direction association between the second monitoring device that emits the acoustic and optical signal and the moving direction, so that the relevant personnel can make a judgment on the first direction (because the first direction is very close to the moving direction) to determine the subsequent tracking judgment of the second monitoring device, and when the above two steps are repeated, if there are multiple second monitoring devices arranged in close proximity, the latest tracking signal can be continuously obtained and responded to according to the position change information, so as to form a dynamic tracking of the movement of the first monitoring device, so that the relevant personnel can make a more accurate judgment on the movement of the first monitoring device, which is conducive to tracking the first monitoring device or understanding the situation after the first monitoring device is moved.

[0110] When this embodiment is applied, through the combination of the first tracking warning information and the second tracking warning information, it is possible to "track" the first monitoring device after it is "lost", and a more reliable tracking method can be provided for relevant personnel.

[0111] As an optional embodiment of the present invention, if the second monitoring device is abnormal, determining the first monitoring device that covers the monitoring device, the monitoring device includes the first monitoring device and the second monitoring device includes:

[0112] Step: screening a number of monitoring devices whose monitoring ranges cover the first monitoring device and the second monitoring device;

[0113] Specifically, in the pre-set monitoring arrangement, the first monitoring device and the second monitoring device are covered by the monitoring range of at least one monitoring device. The monitoring range of each monitoring device is known. It is sufficient to directly screen the first monitoring device or the second monitoring device, or directly screen the corresponding installation areas of the two. When there is a monitoring range covering the installation area, the corresponding number of monitoring devices that meet the conditions indicates that there are one or more.

[0114] Step: Detect a first monitoring device in a normal monitoring state among a plurality of monitoring devices.

[0115] Specifically, a detection instruction is sent to several monitoring devices to require the monitoring devices in a normal monitoring state (such as an online monitoring state) to feedback a response signal. When a response signal of a monitoring device is received, it indicates that the monitoring device is the first monitoring device.

[0116] It should be understood that by successively determining the monitoring device and the first monitoring device, it is not necessary to detect all monitoring devices covering the monitoring device, and thus the first monitoring device can be quickly determined.

[0117] like Figure 4 As shown, as an optional embodiment of the present invention, detecting the second abnormal condition of the first monitoring device and the second monitoring device according to the monitoring information of the first monitoring device includes:

[0118] Step S141: determining whether the installation area of ​​the monitoring device is abnormal according to the monitoring information;

[0119] It should be noted that the detection in this embodiment can be based on the first monitoring device and the second monitoring device performing the detection separately, or can be performed simultaneously.

[0120] Specifically, the video and / or image frames of the monitoring information are analyzed, and the video and / or image frames that include the installation area and meet the preset frame size are segmented, and then frame-by-frame detection is performed to determine whether each frame meets a first preset similarity with the installation image of the monitoring device in a normal installation state. If so, it can be determined that the installation of the monitoring device is at least not a problem on the surface, and the detection continues. If not, it is determined that the installation area is abnormal, which may be caused by human intention or lack of knowledge of the monitoring device (for example, the lack of building monitoring signs and warnings of the monitoring device, etc.), causing the monitoring device of the building to leave the original installation area.

[0121] Step S142: If there is an abnormality, detect whether there is a suspicious object in the monitoring information. If so, extract the first abnormal image including the monitoring equipment and the suspicious object in the monitoring information and report it. If not, obtain the second abnormal image used to characterize the abnormality of the installation area and report it. Generally speaking, this situation may occur in both the first monitoring equipment and the second monitoring equipment.

[0122] Specifically, when an abnormality occurs, since it is detected frame by frame and monitored from front to back in chronological order, when a suspicious object is detected in a certain frame, such as a person or a robot and drone operated by a person, the suspicious object needs to meet the condition of contact with the monitoring device, so it can be a standard (training) image that is in contact with the preset target and the monitoring device that satisfies the second preset similarity. At this time, the target is determined to be a suspicious object, and a certain frame in which the suspicious object and the monitoring target are released is also the first abnormal image. If there is no abnormal object, the person or the robot and drone operated by a person may just pass through the installation area and be far enough away from the monitoring device. At this time, the second abnormal image is an image corresponding to the first preset similarity, and the second image may not include the suspicious object. It should be noted that the first preset similarity and the second preset similarity can be set according to actual needs.

[0123] Step S143: If normal, a third abnormal image is obtained and reported, which is used to indicate that the installation area is normal but the monitoring device is abnormal.

[0124] Specifically, when normal, in this case both the first monitoring device and the second monitoring device are abnormal. This situation is generally likely to occur in the second monitoring device, indicating that the (second) monitoring device in the installation area is at least normal on the surface. At this time, it is very likely caused by internal abnormalities of the monitoring device, such as damage to internal circuits.

[0125] The targets involved above may include installation areas and suspicious objects. Target recognition can be achieved based on the YOLO algorithm, SSD algorithm, and R-CNN algorithm in the prior art, which will not be described here.

[0126] In summary, the first abnormal image can provide a tracing basis for abnormal monitoring equipment caused by human factors, etc. The second abnormal image can be identified as abnormal monitoring equipment after the installation area performs abnormally (this may be non-human factors, such as natural factors such as wind force that cause abnormal installation area and thus abnormal monitoring equipment, such as leaving the installation area, or the working environment of the installation area is destroyed, etc.), and the third abnormal image is that the installation area is normal but the monitoring equipment is abnormal. The above situations can provide reliable criteria for timely maintenance of monitoring equipment, especially the first abnormal image. The first abnormal image can be sent to the receiving device of the reported image, and a tracking instruction can be generated according to the first abnormal image, and then distributed to all other monitoring devices. When other monitoring devices (preferably the second monitoring device with the same moving direction as the suspicious object and within the preset area size) identify suspicious objects and / or monitoring devices that meet the first abnormal image according to the first abnormal image, at this time, as long as one of the three situations is met, an alarm message of successful tracking will be reported. The alarm message contains the location of the monitoring device, which can provide a more reliable tracking basis for tracking suspicious objects and / or monitoring devices.

[0127] like Figure 5 As shown, as another preferred embodiment of the present invention, on the other hand, a building monitoring and management system, applying the building monitoring and management method in the above embodiment, comprises:

[0128] The monitoring abnormality judgment module 100 is used to judge whether a second monitoring device having a linkage relationship with the first monitoring device has an abnormality if it is determined that the first monitoring device has an abnormality, wherein the linkage relationship is used to indicate that the first monitoring device and the second monitoring device maintain a communication connection under normal conditions, and the first monitoring device sends an emergency message to the second monitoring device when a position abnormality occurs;

[0129] The condition acquisition module 200 is used to acquire the emergency information sent by the first monitoring device when a position abnormality occurs and stored in the second monitoring device if no abnormality occurs in the second monitoring device, wherein the emergency information includes updated monitoring information of the building and position change information of the first monitoring device;

If the second monitoring device does not have an abnormality, the emergency information sent by the first monitoring device when the position abnormality occurs and stored in the second monitoring device is obtained, and the state of the building and the first abnormal condition of the first monitoring device are detected according to the emergency information; even if the first monitoring device is abnormal, the emergency information including the updated monitoring information and the position change information can be obtained through the second monitoring device, so as to determine the state of the building. state and the first abnormal condition of the first monitoring device. If the second monitoring device is abnormal, determine the first monitoring device covering the monitoring device, the monitoring device includes the first monitoring device and the second monitoring device; detect the second abnormal condition of the first monitoring device and the second monitoring device according to the monitoring information of the first monitoring device.

The above can realize that the first monitoring device and the second monitoring device can realize the transmission of monitoring information in the normal state according to the data update requirements when communicating normally. By obtaining emergency information, even if the first monitoring device of the building is abnormal, it is ensured that the latest monitoring information can still be obtained. When both the first monitoring device and the second monitoring are abnormal, effective maintenance can be performed according to the actual abnormal type of the first monitoring device and the second monitoring device. The abnormal situations in both cases (the state of the building, the first abnormal condition and the second abnormal condition) can provide reliable judgment for the operation and maintenance personnel on the rapid operation and maintenance of the monitoring equipment, thereby facilitating the rapid monitoring and recovery of the building and improving the safety of building monitoring.
