Description

Technical Field

[0001] The present invention relates to the technical field of construction monitoring, and in particular to a safety risk monitoring and early warning system for distribution network operators. Background Art

[0002] The construction of distribution network is an important project to ensure the normal operation of the national economy. The environment of the distribution network construction site is complex and diverse. During the construction process, construction workers are required to professionally and strictly follow the operation guidelines to perform standardized operations. Usually, in order to ensure that construction workers can work safely, they will be filmed and monitored in a standardized manner during the operation of the workers to avoid accidents caused by their illegal operations. Under the existing technology, the safety monitoring of workers is mostly focused on whether the workers comply with the operation guidelines and whether they wear and / or wear safety equipment as required. However, when the distribution network is operated under the complex terrain conditions in the rainy season, mountain and / or soil landslides will also pose a safety threat to the workers and cause damage to the distribution network equipment. Such incidents are not uncommon. However, it is difficult for the existing technology to conduct safety monitoring of distribution network construction workers under the complex terrain conditions in the rainy season. At the same time, it is also difficult to predict potential risks by monitoring the operating actions of construction workers. If the construction workers cannot be monitored in a multi-dimensional and three-dimensional manner, it will be difficult to control safety risks. Summary of the invention

[0003] In view of the above-mentioned problems existing in the existing safety monitoring and early warning system for distribution network operators, the present invention is proposed.

[0004] Therefore, one of the objects of the present invention is to provide a distribution network worker safety risk monitoring and early warning system, which utilizes the collected rainfall, topography and soil bearing data in the distribution network construction area, and through pre-setting operating actions of different operating modes, the operating actions of the construction workers are compared with the preset operating actions. It can perform multi-dimensional and three-dimensional safety monitoring of the construction workers, improve the reliability of safety monitoring, ensure the safety of construction workers to a higher degree, and enhance the control of safety risks.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] On the one hand, the present invention provides a distribution network operator safety risk monitoring and early warning system, comprising:

[0007] An information acquisition unit, the information acquisition unit comprising a CCD camera, an image data compression module and an image capture module;

[0008] The CCD camera is used to obtain image data of the operator's working process;

[0009] The image data compression module is used for compressing the image data;

[0010] The image capture module is used to capture the image data of the pre-selected area in the image data compression module;

[0011] The action data acquisition module is used to collect the historical process actions of the operator from the beginning to the end of the operation, and to summarize and divide the historical process actions according to the operation purpose. At the same time, the action prediction model is constructed based on the historical process actions of different operation purposes;

[0012] A fusion analysis unit, the fusion analysis unit comprising a motion feature interception module and a time feature acquisition module;

[0013] The action feature interception module is used to obtain historical feature operation actions in different operation purposes;

[0014] The time feature acquisition module is used to acquire the processes corresponding to the feature operation actions in different operation purposes.

[0015] As a preferred solution of the present invention, the information acquisition unit also includes obtaining soil moisture value data of the preset distribution network construction area at the time of the historical maximum monthly rainfall, and presetting a safety threshold based on the soil moisture value data when a landslide occurred in the preset distribution network construction area in the past. When the soil moisture value data of the preset distribution network construction area in the future period is higher than the safety threshold, the system determines that the preset distribution network construction area is in a landslide risk state, otherwise, it does not determine, and calculates the change law of the soil moisture value data based on the hourly rainfall data in the historical maximum monthly rainfall in the preset distribution network construction area, and calculates it according to the following formula:

[0016] Among them, w i represents the maximum hourly rainfall data collected for the ith time in the maximum monthly rainfall;

[0017] In the formula, ξ represents the average change value of soil moisture in the preset distribution network construction area during the maximum monthly rainfall, and x i It represents the maximum average change value data of soil moisture when the soil landslide occurs during the i-th time of the maximum monthly rainfall, and a critical threshold is preset based on the maximum average change value data. When the maximum average change value data of soil moisture collected in the future period is higher than the critical threshold, the system issues a safety warning, otherwise, no warning is issued;

[0018] At the same time, if the maximum average change value data of soil moisture collected in the future period is higher than the critical threshold and no soil landslide occurs, the critical threshold is reassigned;

[0019] b represents the historical number of soil landslides that occurred in the preset distribution network construction area, and n represents the soil bearing capacity data when historical soil landslides occurred.

[0020] As a preferred solution of the present invention, the operation process required for different construction work purposes is preset, and the operation action image matching the operation process is obtained, and the key frame image of the characteristic action is obtained in the operation action image, and the key frame image is divided into θ1, θ2, ..., θ n , where n represents the nth key frame image. When the system does not detect the characteristic action that is consistent with the operation process, the system will issue an early warning, otherwise, no early warning will be issued.

[0021] As a preferred solution of the present invention, the operating procedures of operators in historical construction operations in which illegal operations and / or safety accidents occurred are obtained, and the operating procedures in which illegal operations and / or safety accidents occurred are sorted from the highest to the lowest number of times, and the previous operating actions in which illegal operations and / or safety accidents occurred in different operating procedures are collected, and the corresponding action features are obtained based on the previous operating actions. When the system monitors that an operation procedure has an action feature corresponding to the previous operation action during construction operations in a future period, the system determines it as an erroneous operation and issues a warning. Otherwise, no warning is issued.

[0022] As a preferred solution of the present invention, the corresponding operation processes are monitored at different levels in order of most to least when a safety accident occurs, and the different levels of monitoring are divided into high, medium and low levels in a step-by-step manner, wherein high-level monitoring and medium-level monitoring are both full-process monitoring, and low-level monitoring is non-full-process monitoring.

[0023] As a preferred solution of the present invention, the soil bearing data includes the weight of the distribution network equipment and the weight increased due to rainfall, and collects the minimum weight portion increased due to rainfall when a landslide occurred in history, and presets a weight threshold based on the minimum increased weight portion. When the weight increased due to rainfall in the distribution network construction area preset in the future time period exceeds the weight threshold, the system issues an early warning, otherwise, no early warning is issued.

[0024] As a preferred solution of the present invention, it also includes a monitoring terminal for recording the communication base station and / or the communication base station operator matching the preset construction operation area, receiving the field data uploaded by the collection monitoring point, and updating the background data at the same time;

[0025] When a system warning signal is issued in the monitoring area, a request for obtaining information on the warning status of the power transmission line is initiated to the corresponding communication base station and / or the communication base station operator in the preset monitoring area.

[0026] As a preferred solution of the present invention, an image set is generated according to the acquired key frame images, and the key frame images in the image set are preprocessed.

[0027] On the other hand, the present invention provides a method for a distribution network operator safety risk monitoring and early warning system, comprising the following steps:

[0028] Acquire image data of the operator's working process, compress and process the image data, and intercept image data of a preselected area;

[0029] Collect the historical process actions of the operator from the beginning to the end of the operation, and summarize and divide the historical process actions according to the operation purpose. At the same time, build an action prediction model based on the historical process actions of different operation purposes;

[0030] Acquire historical characteristic operation actions in different operation purposes, and collect the processes corresponding to the characteristic operation actions in different operation purposes;

[0031] Preset the operation process required for different construction work purposes, and obtain the operation action image matching the operation process, and at the same time obtain the key frame image of the characteristic action in the operation action image;

[0032] Generating an image set according to the acquired key frame images, and preprocessing the key frame images in the image set;

[0033] The operating procedures of operators in historical construction operations that resulted in illegal operations and / or safety accidents are obtained, and the operating procedures in which illegal operations and / or safety accidents occurred are sorted from the most to the least frequent. When the system detects that an operating procedure has action features corresponding to the previous operation during construction operations in future time periods, the system determines it as an erroneous operation and issues a warning. Otherwise, no warning is issued.

[0034] Beneficial effects of the present invention: By collecting rainfall, topography and soil bearing data in the distribution network construction area, the present invention can effectively analyze and predict the occurrence of soil landslides, and issue timely warnings, thereby warning workers to evacuate before a safety accident occurs.

Furthermore, multi-dimensional and three-dimensional safety monitoring of the construction workers can be performed, thereby improving the reliability of safety monitoring, ensuring the safety of construction workers to a higher degree, and enhancing the control of safety risks.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0041] It is difficult to conduct safety monitoring of distribution network construction workers in the complex terrain during the rainy season using existing technologies. It is also difficult to predict potential risks by monitoring the operating actions of construction workers. If multi-dimensional and three-dimensional safety monitoring of construction workers cannot be carried out, it will be difficult to control safety risks.

[0042] Based on this, the present invention proposes a distribution network operator safety risk monitoring and early warning system, which collects rainfall, topography and soil bearing data in the distribution network construction area, and through pre-setting operating actions of different operating modes, compares the operating actions of the construction workers with the preset operating actions. It can perform multi-dimensional and three-dimensional safety monitoring of the construction workers, improve the reliability of safety monitoring, ensure the safety of construction workers to a higher degree, and enhance the control of safety risks.

[0043] The present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0046] The CCD camera 1101 is used to obtain image data of the operator's working process;

[0047] The image data compression module 1102 is used for compressing image data;

[0048] The image capture module 1103 is used to capture the image data of the pre-selected area in the image data compression module 1102;

[0049] In the information acquisition unit 110, it also includes obtaining the soil moisture value data of the preset distribution network construction area at the time of the historical maximum monthly rainfall, and setting a safety threshold based on the soil moisture value data when the preset distribution network construction area has a landslide in history. When the soil moisture value data of the preset distribution network construction area in the future period is higher than the safety threshold, the system determines that the preset distribution network construction area is in a landslide risk state, otherwise, it does not determine, and calculates the change law of the soil moisture value data based on the hourly rainfall data in the historical maximum monthly rainfall in the preset distribution network construction area, and calculates it according to the following formula:

[0050] Among them, w i represents the maximum hourly rainfall data collected for the i-th time in the maximum monthly rainfall;

[0051] In the formula, ξ represents the average change value of soil moisture in the preset distribution network construction area during the maximum monthly rainfall, and x i It represents the maximum average change value data of soil moisture when the soil landslide occurs during the maximum monthly rainfall, and the critical threshold is preset based on the maximum average change value data. When the maximum average change value data of soil moisture collected in the future period is higher than the critical threshold, the system will issue a safety warning, otherwise, no warning will be issued;

[0052] At the same time, if the maximum average change value data of soil moisture collected in the future period is higher than the critical threshold and no soil landslide occurs, the critical threshold is reassigned;

[0053] b represents the historical number of soil landslides in the preset distribution network construction area, and n represents the soil bearing data when historical soil landslides occurred;

At the same time, the key frame image of the characteristic action is obtained in the operation action image, and the key frame image is divided into θ1, θ2, ..., θ n , where n represents the nth key frame image. When the system does not detect the characteristic action that matches the operation process, the system will issue an early warning, otherwise, no early warning will be issued;

[0060] Further, an image set is generated according to the acquired key frame images, and the key frame images in the image set are preprocessed;

[0061] The operating procedures of operators in historical construction operations that resulted in illegal operations and / or safety accidents are obtained, and the operating procedures in which illegal operations and / or safety accidents occurred are sorted from the most to the least frequent. At the same time, the previous operating actions in which illegal operations and / or safety accidents occurred in different operating procedures are collected, and the corresponding action features are obtained based on the previous operating actions. When the system detects that an operating procedure has an action feature corresponding to the previous operating action during construction operations in the future period, the system determines it as an erroneous operation and issues a warning. Otherwise, no warning is issued.

[0062] The corresponding operating processes will be monitored at different levels in order of the most to least safety incidents, and the different levels of monitoring will be divided into high, medium and low levels. Among them, high-level monitoring and medium-level monitoring are full-process monitoring, and low-level monitoring is non-full-process monitoring.

[0064] When a system warning signal is issued in the monitoring area, a request for obtaining information on the warning status of the power transmission line is initiated to the corresponding communication base station and / or the communication base station operator in the preset monitoring area.

[0065] According to the above-mentioned distribution network operator safety risk monitoring and early warning system, the present invention also provides a working method applied to the system, as follows:

[0066] Acquire image data of the operator's working process, compress and process the image data, and intercept image data of a preselected area;

At the same time, by presetting operating actions for different operating modes and comparing the operating actions of the construction workers with the preset operating actions, it can be predicted whether the operating actions of the workers will cause safety risks, thereby providing multi-dimensional and three-dimensional safety monitoring for the construction workers, thereby improving the reliability of safety monitoring, ensuring the safety of construction workers to a higher degree, and enhancing the control of safety risks.
