Fig. 3 is a flowchart of an intelligent supervision method for a construction site according to an embodiment of the present invention, where the intelligent supervision method is used for the supervision system shown in fig. 1, and the embodiment is described by taking an example that the intelligent supervision system includes a positioning base station deployed on the construction site, as shown in fig. 3, the method includes:
301. the positioning base station collects operation information of a construction site.
The positioning base station is deployed on a construction site, and the specific position of the positioning base station can be determined according to the shape of the construction site and the size of the construction site. For example, the construction site is a rectangular area, and the positioning base stations can be deployed at four corners of the construction site. The embodiment does not limit the specific position of the positioning base station, and only needs to ensure that any position of the construction site is within the coverage range of the positioning base station.
The positioning base station can carry out wireless communication with the positioning tag, the positioning tag transmits a wireless signal, and if the positioning tag is in the coverage range of the positioning base station, the wireless signal of the positioning tag can be received. Therefore, the positioning tag can be deployed on a construction site, and the operation information can be acquired through communication between the positioning base station and the positioning tag.
The wireless signals carry different information, the determined operation information is different, and the operation information obtained on the construction site is different.
Alternatively, the process of acquiring the job information may include the following four ways:
firstly, the operation information comprises the personnel identification of the constructor: the positioning base station receives a wireless signal transmitted by a positioning tag worn by a constructor, and the wireless signal carries the personnel identification of the constructor.
In the embodiment of the invention, a unique personnel identifier is distributed to each constructor on a construction site, and the personnel identifier represents the identity of the constructor. The personnel identification may be the name of the constructor, an employee number, or other identification.
And moreover, a unique positioning tag is distributed to each constructor, the personnel identification of the constructor is written into the positioning tag, and the personnel identification is carried by the wireless signal transmitted by the positioning tag. The positioning tag can be worn on the safety helmet of the constructor or worn on the wrist of the constructor and the like.
When the positioning base station receives the wireless signal carrying the personnel identification, the construction personnel to which the personnel identification belongs can be determined to be located in the coverage range of the positioning base station, and at the moment, the construction personnel can also be considered to be located in a construction site.
Secondly, the operation information comprises the distance between the positioning base station and the constructor: the positioning base station receives a wireless signal transmitted by a positioning tag worn by a constructor, the wireless signal carries the transmission time of the wireless signal, the positioning base station receives the wireless signal and records the time for receiving the wireless signal as the receiving time of the wireless signal, and the positioning base station determines the distance between the positioning base station and the constructor according to the receiving time and the transmitting time of the wireless signal.
The positioning base station can determine the time difference between the transmitting time and the receiving time according to the receiving time and the transmitting time of the wireless signal, namely the time for the wireless signal to propagate from the positioning label to the positioning base station, and can determine the distance between the positioning base station and the positioning label, namely the distance between the positioning base station and constructors according to the time difference and the propagation speed of the wireless signal.
Thirdly, the operation information comprises the distance between the positioning base station and the constructors and the personnel identification of the constructors: the positioning base station receives a wireless signal transmitted by a positioning tag worn by a constructor, the wireless signal carries the transmission time of the wireless signal and the personnel identification of the constructor, and the distance between the positioning base station and the constructor is determined according to the reception time and the transmission time of the wireless signal.
Fourthly, the operation information comprises the distance between the positioning base station and the construction article: the positioning base station receives wireless signals transmitted by positioning tags deployed on construction articles, the wireless signals carry the transmission time of the wireless signals, and the distance between the positioning base station and the construction articles is determined according to the receiving time and the transmission time of the wireless signals.
In the embodiment of the invention, a unique positioning label is distributed to each construction article on a construction site and is deployed on the construction article. When the constructor moves the construction article, the positioning label moves along with the construction article. Therefore, when the positioning base station receives the wireless signal transmitted by the positioning tag, a construction article can be determined to be positioned in the coverage range of the positioning base station.
Optionally, after the positioning base station acquires information such as a staff identifier of a constructor, transmission time and reception time of a wireless signal, the acquired information can be directly used as operation information without performing other processing, and the operation information is reported to the management server and analyzed by the management server according to the received operation information.
For example, the operation information of the construction site includes the sending time and the receiving time of the wireless signal, the positioning base station does not process the sending time and the receiving time of the wireless signal and directly uploads the wireless signal to the management server, and the management server determines the distance between the positioning base station and the constructor according to the sending time and the receiving time of the wireless signal.
Alternatively, the work information of the construction site includes the transmission time and reception time of the wireless signal and the worker identification of the constructor. The positioning base station does not process the sending time and the receiving time of the wireless signals and the personnel identification of the constructors and directly uploads the wireless signals to the management server, and the management server determines the distance between the positioning base station and the constructors according to the sending time and the receiving time of the wireless signals.

Alternatively, routing equipment may be deployed at the construction site, the positioning base station sends the operation information to the routing equipment, and the routing equipment transmits the operation information to the optical fiber communication system in the yard or the valve room. In addition, if the construction site is far away from the station yard or the valve chamber, the routing equipment can expand the coverage area of the routing equipment in a wireless access point, a network bridge or microwave mode, and therefore the operation information can be transmitted to the optical fiber communication system in the station yard or the valve chamber.

In one possible implementation manner, the operation information includes a person identifier of a constructor, and the management server determines whether the constructor belongs to a preset constructor of the construction site based on the person identifier of the constructor, and determines that a safety risk exists in the construction site when the constructor does not belong to the preset constructor.
The management server can acquire a preset constructor list of the construction site in advance, wherein the list comprises the personnel identification of the constructor allowed to enter the construction site, and indicates that the constructor in the list is allowed to enter the construction site, and the constructor not belonging to the list is not allowed to enter the construction site. When the personnel identification uploaded by the acquisition equipment is acquired, whether the preset constructor list comprises the personnel identification is judged, and therefore whether the constructor belongs to the preset constructor on the construction site is determined.
In another possible implementation manner, if a specific position of the positioning tag is to be determined, at least three positioning base stations need to be deployed on a construction site, and the position of the positioning tag is determined according to distances between the at least three positioning base stations and the positioning tag. Therefore, any position of the construction site needs to be ensured to be within the coverage range of at least three positioning base stations.
The operation information comprises the distance between the plurality of positioning base stations and each constructor, the management server determines the position of each constructor according to the positions of the plurality of positioning base stations and the distance between the plurality of positioning base stations and each constructor, and determines whether each constructor is located in the construction site according to the position of each constructor, so that the number of the constructors in the construction site is determined. When the number of the constructors is determined to exceed the first numerical value, the fact that the number of the constructors on the construction site is too many is determined, and safety risks exist.
The management server stores the maximum number of constructors allowed by a construction site, namely a first numerical value, and also stores the position of each positioning base station in advance.
In another possible implementation manner, the operation information includes a staff identifier of each constructor and distances between the plurality of positioning base stations and each constructor, the management server determines the position of each constructor according to the positions of the plurality of positioning base stations and the distances between the plurality of positioning base stations and each constructor, determines the constructor located in the construction site according to the position of each constructor, and determines that the construction site has a safety risk when the constructor located in the construction site does not belong to a preset constructor.
The management server stores in advance a site position, for example, a boundary coordinate of the site. After acquiring the position of each constructor, the management server can determine each constructor in the construction site.
The management server can acquire a preset constructor list of the construction site in advance, wherein the list comprises the personnel identification of the constructor allowed to enter the construction site, and indicates that the constructor in the list is allowed to enter the construction site, and the constructor not belonging to the list is not allowed to enter the construction site. And when the constructors located in the construction site are determined, judging whether the preset constructor list comprises the personnel identification of the constructors or not, thereby determining whether the constructors belong to the preset constructors of the construction site or not. When the constructors which do not belong to the preset constructors exist in the constructors positioned on the construction site, the external constructors are determined to enter the construction site, and safety risks exist.
In another possible implementation manner, the operation information includes distances between a plurality of positioning base stations and each constructor, and the management server determines the position of each constructor according to the positions of the plurality of positioning base stations and the distances between the plurality of positioning base stations and each constructor; and the management server determines the number of the constructors in the target area in the construction site according to the position of each constructor, and determines that the construction site has safety risks when determining that the number of the constructors exceeds a second numerical value.
The management server stores the position of the target area in advance, and the position may be boundary coordinates of the target area. The target area may be an area with a high risk factor in a construction site or an area with a requirement on the number of constructors. In addition, the target area may be designated on the management server by a manager, so that the management server can acquire the position of the target area. The management server also stores a second value, which is the maximum number of constructors allowed to exist in the target area.
For example, when maintenance work is performed at a construction site, operations are sometimes required to be performed on some equipment at the construction site, such as maintenance operations on a tank, but the tank has a limited number of workers that can be carried by the tank, and when the number of workers operating on the tank is too large, there may be a safety risk. The management personnel can set the area where the oil tank is located as a target area on the management server, set the maximum number of constructors which can be borne in the target area, define a detailed operation site and monitor the number of the constructors in the site.
In another possible implementation manner, the operation information includes distances between a plurality of positioning base stations and any construction article, and the position of the construction article is determined according to the positions of the plurality of positioning base stations and the distances between the plurality of positioning base stations and the construction article; when the position of the constructor is determined to be a preset dangerous position, the safety risk in the construction site is determined, and intelligent identification of the placement of construction articles in the construction site is realized.
The preset dangerous positions can be positions preset in the management server by managers, the managers can judge which positions of the construction site are not suitable for placing construction articles according to construction specifications or working experience, coordinates of the positions are input into the management server, and the positions are the preset dangerous positions.
For example, the preset dangerous position may be an edge position of a certain higher object, such as an edge position of a construction bracket, when a construction article is placed at the edge of the higher position, the construction article may fall from a high place due to misoperation of a constructor or wind action of a site, damage to the construction article may be caused, and safety of other constructors may be endangered.
In addition, some information of the construction site may be input in advance before the management server supervises the construction site. For example, before the management server supervises the construction site, the position information of the construction site including at least the size of the construction site, the position of each construction area, and the like may be input to the management server. The specific manner of inputting the position information of the construction site into the management server may be: and the management personnel inputs the construction drawing into the management server, or the management personnel draw the position information of the construction site on the management server in a hand drawing mode. And after receiving the operation information, the management server analyzes the operation information based on the position information of the construction site input in advance and determines whether the construction site has safety risks according to the analysis result.
304. When the safety risk exists in the construction site, the management server sends alarm information.
The alarm information may include alarm bell sound, alarm prompt information and other alarm information in various forms. For example, the alarm information may be an alarm ring or an alarm prompt message, or may be an alarm ring sent while the alarm prompt message is displayed. The alarm information is only required to be noticed by the administrator, and the form of the alarm information is not limited in this embodiment.
In one possible implementation, different security risks correspond to different alarm information to achieve differentiated reminding.
The alarm information is taken as an alarm ring for example to explain, a management server stores various alarm rings in advance and the corresponding relation between the alarm rings and the safety risk types, and after the management server identifies the safety risk, the management server determines the corresponding alarm ring according to the type of the safety risk and sends the alarm ring. For example, when the management server recognizes that a constructor at a construction site exceeds a first value, an alarm bell 1 is issued, and when the management server recognizes that other constructors not belonging to the construction site enter the construction site, an alarm sound 2 is issued.
In one possible implementation, the alarm prompt message carries description information of the security risk.
For example, the management server is provided with a display screen, when the management server identifies that other construction personnel which do not belong to the construction site enter the construction site, alarm prompt information pops up on the display screen of the management server, and the alarm prompt information displays that external personnel exist in the construction site, so that the construction personnel can quickly find out existing safety risks and take corresponding measures to ensure the safety of the construction site.
In a possible implementation manner, the alarm information may also carry guidance data corresponding to the security risk. Constructors can determine which measures to take according to the guidance data, and safety risks existing in a construction site can be safely solved.
It should be noted that, after determining the position of each constructor, the management server may further store the position of each constructor, generate an action trajectory of each constructor based on a plurality of positions of each constructor, store the action trajectories of the constructor and the constructor correspondingly, and subsequently may retrieve the action trajectory at any time for query. In addition, the action trajectory may be generated in a plan view of the construction site in the management server in order to more intuitively understand the construction process of the constructor.
According to the intelligent supervision method provided by the embodiment of the invention, the positioning base station is deployed on the construction site, and the constructors or the construction articles wear the positioning tags, so that the positioning base station acquires the position information of the constructors or the construction articles, the positioning of the constructors, the monitoring of the quantity of the constructors and the intelligent identification of the placement of the construction articles are realized by processing the position information of the constructors, and the operation safety of the construction site is ensured by supervising various types of safety risks.
Fig. 4 is a flowchart of an intelligent supervision method for a construction site according to an embodiment of the present invention, where the embodiment takes a collection device as a camera device for example, and as shown in fig. 4, the method includes:
401. the camera device obtains a video of a construction site.
The image pickup device can be any device with a shooting function, and the construction site is shot by the image pickup device so as to obtain a video of the construction site.
A plurality of camera devices can be deployed on a construction site to ensure that each position of the construction site can be shot, and the construction site is supervised in an all-around manner. For example, 2 or more than 2 image pickup devices may be disposed around the oil tank in a certain construction site, so as to ensure that the operation condition of the oil tank by the constructor can be photographed. The mode reduces the number of the camera devices, saves the cost and also improves the video analysis efficiency of the subsequent management server.
402. The camera shooting device sends the video to the communication device, and the communication device receives the video and forwards the video to the management server.
After the video is collected by the camera device, the collected video can be sent to the communication device in real time, or the video collected in the preset time interval can be sent to the communication device at preset time intervals.
Wherein, the step 402 is described in the step 302, and is not described herein again.
403. The management server identifies the video, and identifies the type of a construction article, the position of the construction article and the position of a constructor; and when the construction article is determined to be a preset type of construction article and is in a motion state and the constructor is positioned in a target area, determining that the safety risk exists in the construction site, and sending alarm information, wherein the target area refers to an area to which the position of the construction article belongs.
The management server may analyze the video according to an image recognition technology, which may be a target recognition technology, a face recognition technology, and the like, and the embodiment of the present invention is not limited thereto.
Construction sites exist for various types of construction articles, such as: gas cylinders, cranes, tank trucks, etc. When a constructor uses some construction articles, the construction articles may be in a moving state, and when the construction articles are in a moving state, the constructor near the construction articles may be injured. For example, the construction article is a crane, and in a construction site, when the crane is in a moving state, it may be that a constructor operates the crane to hoist one article from one position to another position, and dropping off of the hoisted article may occur when the crane hoists the article, and thus, there is a danger when the constructor passes near the crane. Therefore, some types of construction articles may be previously set in the management server, and the preset types of construction articles may cause damage to nearby construction personnel in a moving state.
The management server, after recognizing the type of construction article, the location of the construction article, and the location of the constructor, may determine whether the construction article is in a motion state based on the location of the construction article. When the position of a construction article in the video changes along with the change of time, determining that the construction article is in a running state; and when the position of the construction article in the video does not change along with the change of time, determining that the construction article is in a static state.
When the type of the construction article is determined to be a preset type and is in a motion state, a target area is determined based on the position of the construction article, the target area comprises the position of the construction article, and when a constructor is located in the target area, it is determined that a safety risk exists in a construction site.
The method for determining the target area can comprise the following steps: and acquiring the position of the construction article, and determining a circular target area by taking the position of the construction article as a circle and taking the preset length as a radius. Therefore, no matter which direction is close to the construction article, the alarm can be triggered, and the safety of constructors is protected more comprehensively. Optionally, the management server may further determine a target area in any shape, such as a rectangle and an ellipse, based on the position of the construction article, the shape of the target area is not limited in the embodiment of the present invention, and the specific shape of the target area may be set according to an area where the construction article poses a risk to the constructor.
In another possible implementation manner, the management server acquires the motion trail of the construction article according to the plurality of identified positions of the construction article, and determines the region to which the motion trail belongs as the target region. The target area determined by the management server comprises the motion track of the construction article, so that the constructor can be reminded in time when the constructor enters the construction range of the construction article by mistake.
When constructors use the construction articles, some construction articles may reciprocate, after the reciprocating motion of the construction articles is determined, the motion trail of the construction articles can be obtained, and the target area is determined based on the motion trail of the construction articles. Wherein, the manner of determining whether the construction article performs the reciprocating motion may include: the management server identifies a plurality of positions of the construction article according to a plurality of video frames in the video, and determines whether the construction article reciprocates or not based on the positions of the construction article and the time of the video frames corresponding to the positions.
Optionally, the positions of the construction articles in the plurality of video frames are obtained, the positions of the construction articles in the plurality of video frames are sequentially connected according to the time sequence of the video frames, the motion track of the construction articles is obtained, and based on the motion track of the construction articles, whether the motion state of the construction articles is a reciprocating state or not can be determined. In addition, the method of determining the target area based on the motion trajectory of the construction article may include: and determining an elliptical target area according to two end points of the motion trail, wherein the two end points are focuses of the ellipse. In addition, a rectangular target area may also be determined based on the motion trajectory, and the method for determining the target area based on the motion trajectory is not limited in the embodiment of the present invention.
In another possible implementation manner, the construction article comprises a first component and a second component, the position of the first component is fixed, the second component swings, and the management server determines an area obtained by projecting the swing track of the second component on the ground as the target area.
Some construction articles move on the ground during construction, and some construction articles move above the ground. For example, the construction article is a tower crane, the tower crane comprises a tower body and a suspension arm, wherein the first part of the tower crane is the tower body, the second part of the tower crane is the suspension arm, the suspension arm can swing back and forth during working, when a constructor passes under the suspension arm, if the article lifted by the suspension arm falls, the constructor under the suspension arm can be injured, and therefore, when the suspension arm lifts the article, the constructor can not pass under the suspension arm. The management server determines the area obtained by projecting the swing track of the suspension arm on the ground as a target area, so that when a constructor passes below the swing area of the suspension arm, the management server can give an alarm to remind the constructor.
The embodiment of the present invention is described by taking the step 403 to determine whether the safety risk exists in the construction site as an example, but in another embodiment, the step 403 may not be executed, and whether the safety risk exists in the construction site may be determined in other manners, which only needs to ensure that the manner of determining the safety risk conforms to the construction rule of the construction site.
Because some construction article in the job site all can cause the injury to nearby constructor when starting, or during operation, for example, this construction article is the support of crane, because the driver's cabin of crane is higher, constructor's sight range is limited, consequently, when other constructors are located the support next door, the constructor of driver's cabin probably can not observe, in the removal process of crane, causes the injury to nearby constructor.
Besides the preset type in the above scheme, the administrator can set another preset type in the management server. In one possible implementation manner, the management server analyzes the video, determines whether the construction article in the video is another preset type of construction article, acquires the position of the construction article when the construction article is another preset type of construction article, and determines a target area based on the position of the construction article, wherein the target area includes the position of the construction article. The target area may be a rectangular area, a circular area, or the like. No matter whether the construction article is in a motion state or not, a target area can be defined only by identifying the construction article as a preset type of construction article, and whether constructors are used for monitoring the target area or not is monitored.
In a possible implementation mode, the management server analyzes the video, determines whether protective articles are worn by constructors in the video, and determines that safety risks exist in a construction site if the constructors do not wear the protective articles.
Wherein, the protective articles at least comprise a safety helmet and a work uniform. The unworn protective articles include all protective users who don the protective article, or the protective articles are not completely worn.
In another possible implementation manner, the management server analyzes the video, determines whether the placing posture of the construction article in the video belongs to a preset posture, and determines that the safety risk exists in the construction site when the placing posture of the construction article does not belong to the preset posture.
The management server can pre-store preset postures corresponding to each construction article, when the management server analyzes any video frame in the video, the placing postures of the construction articles are obtained when the construction articles are detected in the video frame, the preset postures of the construction articles are obtained, whether the placing postures of the construction articles are the same as the preset postures is judged, and therefore supervision and management of article placing on an operation site are achieved.
In addition, if some construction operations on the construction site have higher operation difficulty and higher danger coefficient, constructors with rich experience are required to operate the construction site. For example, in a construction site, a maintenance operation needs to be performed on a certain oil tank, and the difficulty factor is high because combustible liquid exists in the oil tank and a constructor needs to perform an operation on the oil tank.
Therefore, in order to standardize the constructors operating the oil tank, in a possible implementation manner, the management server sets a preset constructor list of the target area in advance, and the preset constructor list at least comprises a face image of each preset constructor. The target area may be an area photographed by the image pickup apparatus or an area designated by a manager. The management server analyzes the video shot by the camera equipment, obtains the face image of the constructor in the target area, inquires whether the preset constructor list comprises the face image, and when the face image is not included, the management server indicates that the constructor currently operating the oil tank is not allowed, so that the safety risk of the construction site is determined.
By defining a detailed operation site, the corresponding qualified personnel are standardized to operate on the corresponding operation site, and the safety of the construction site is ensured.
In one possible implementation manner, the management server analyzes the video, determines whether preset dangerous operation exists for constructors in the video, and determines that safety risk exists in a construction site when the preset dangerous operation exists.
Each construction site has its own safe operation specification, so that a constructor or can input operations forbidden in the safe operation specification in the management server, and the operations are preset dangerous operations.
404. When the safety risk exists in the construction site, the management server sends alarm information.
When it is determined that the safety risk exists in the construction site according to the video, the screenshot can be carried out on the video frame with the safety risk identified, and the screenshot is carried in the alarm information.
Wherein, the portions of step 401-404 similar to those of step 301-304 are not described herein again.
According to the intelligent supervision method provided by the embodiment of the invention, the construction site is shot through the camera equipment, the shot video is analyzed by the management server, the wearing of protective articles of construction personnel, the placement of construction articles, the invasion of non-construction personnel in the construction area, illegal and illegal operation and the like can be intelligently identified, the alarm information is sent out when the safety risk exists in the construction site, and the screenshot is carried in the alarm information, so that the construction personnel can rapidly eliminate the safety risk.

504. And when the environmental parameters do not belong to the preset parameter range, the management server determines that the safety risk exists in the construction site and sends alarm information.
In a possible implementation manner, the environmental parameter is a combustible gas concentration, and the management server stores a preset parameter range, where a minimum value of the preset parameter range is 0, and a maximum value is a maximum combustible gas concentration that can be allowed during construction on the construction site. And when the concentration of the combustible gas does not belong to the preset parameter range, the management server determines that the current combustible gas does not meet the construction conditions, and the safety risk exists in the construction site.
In a possible implementation manner, the environmental parameter is a toxic gas parameter, a preset parameter range is stored in the management server, the minimum value of the preset parameter range is 0, the maximum value is the maximum toxic gas concentration which does not affect the body of a constructor, when the toxic gas concentration does not belong to the preset parameter range, the management server determines that toxic gas leakage occurs at a construction site, and the construction site has a safety risk.
