Description

TECHNICAL FIELD

[0001] The present application relates to the field of boundary early warning, and in particular to an overhead line protection zone boundary safety early warning system. BACKGROUND

[0002] When there is an overhead power line above the construction site, it will affect the work in the construction site. When the height of the construction machinery in the construction site is too high, it is easy to cause damage to the overhead power line, thereby causing economic losses. Therefore, the height of the construction machinery in the construction site cannot be too close to the overhead power line.

[0003] At present, a virtual boundary is usually set in the air by using an infrared shooting device, so as to detect whether the construction machinery below has a border crossing behavior. The infrared shooting device is composed of an infrared emitting device and an infrared receiving device. The infrared emitting device emits infrared rays to the infrared receiving device to judge whether there is an object blocking, so as to detect whether there is a border crossing behavior. However, when detecting whether the construction machinery is crossing the border, the infrared shooting device needs to continuously emit infrared rays at a fixed frequency, which is easy to cause waste of electric energy. SUMMARY

[0004] In order to reduce the electric energy loss of the infrared shooting device when detecting the border crossing behavior, the present application provides an overhead line protection zone boundary safety early warning system.

[0005] In a first aspect, the present application provides an overhead line protection zone boundary safety early warning system, which adopts the following technical solution:

[0006] An overhead line protection zone boundary safety early warning system, comprising:

[0007] Two groups of vertical poles, each group of vertical poles is arranged along a straight line and the two groups of vertical poles are parallel to each other;

[0008] A plurality of first infrared emitting devices are arranged on one group of vertical poles, and the plurality of first infrared emitting devices are directed in the same direction. The plurality of first infrared emitting devices emit infrared rays, and the infrared rays represent the boundary.

[0009] A plurality of second infrared receiving devices are arranged on the other group of vertical poles. The plurality of second infrared receiving devices are opposite to the plurality of infrared emitting devices in position and one-to-one correspondence. Each first infrared receiving device receives the infrared rays emitted by the corresponding first infrared emitting device.

[0010] A camera device is used to collect image information of the construction area.

[0011] An electronic device is used to obtain the image information of the construction area collected by the camera device. The image information includes the construction machinery, the power line and the vertical pole.

[0012] characteristics of the construction machinery, the power line and the vertical pole in the image information are obtained by feature recognition on the image information;

[0013] a warning area below the boundary is determined based on the power line and the vertical pole characteristics;

[0014] distance information between the top of the construction machinery characteristic and the boundary is determined when the construction machinery characteristic is detected to enter the warning area;

[0015] the working frequency of the plurality of first infrared emitting devices is determined based on the distance information;

[0016] the plurality of first infrared emitting devices are controlled to operate at the working frequency.

[0017] By adopting the above technical solution, two groups of vertical poles are respectively used to arrange a plurality of first infrared emitting devices and a plurality of first infrared receiving devices, and the first infrared emitting devices and the first infrared receiving devices correspond one-to-one, the first infrared emitting devices emit infrared rays and the first infrared receiving devices receive the infrared rays, the infrared rays represent the boundary, when an object blocks the infrared rays, the first infrared receiving devices cannot receive the infrared rays, thereby realizing detection on whether the object crosses the boundary, the camera device collects image information in the construction area, thereby facilitating grasping the situation in the construction area, the electronic device obtains the image information, and the image information is subjected to feature recognition, thereby being able to recognize the construction machinery characteristic, the power line characteristic and the vertical pole characteristic in the image information, since the length of the vertical pole is set by the staff as needed and the length of the vertical pole represents the maximum height at which the construction machinery can move below the power line, and the size of the warning area is related to the power line itself, therefore, the warning area of the boundary can be determined according to the vertical pole characteristic and the power line, the construction machinery enters the warning area, which indicates that the construction machinery is close to the boundary, at this time, the working frequency of the first infrared emitting device is determined according to the distance information from the top of the construction machinery to the boundary, the smaller the distance information, the closer to the boundary, and the higher the working frequency is required to detect whether the construction machinery crosses the boundary, the greater the distance information, the farther away from the boundary, and the lower the possibility of crossing the boundary, therefore, a lower working frequency is required, the appropriate working frequency of the first infrared emitting device is determined according to the distance information, after the working frequency is determined, the first infrared emitting device is controlled to work at the determined working frequency, thereby reducing the waste of electric energy of the first infrared emitting device when working.

[0018] In another possible implementation manner, the second infrared emission device and the second infrared receiving device are further arranged on the vertical poles at two ends of each group of vertical poles; the second infrared emission device and the second infrared receiving device on each vertical pole are arranged at an angle of 90 degrees; the second infrared emission device on each vertical pole corresponds to the second infrared receiving device on the adjacent vertical pole; and the second detection signal is output when any second infrared receiving device does not receive the infrared ray emitted by the corresponding second infrared emission device.

[0019] The loudspeaker device is electrically connected to the electronic device, and the loudspeaker device outputs the first prompt information when the second detection signal triggered by any second infrared receiving device is received by the electronic device.

[0020] By using the above technical solutions, the second infrared emission device and the second infrared receiving device form a virtual fence around the two groups of vertical poles, so that whether an object enters the construction area between the two groups of vertical poles can be accurately detected. When the second detection signal is received, the loudspeaker device is controlled by the electronic device to output the first prompt information, so that personnel can know that they have entered the construction area between the two groups of vertical poles.

[0021] In a second aspect, the application provides an overhead line protection area boundary safety early warning method, which adopts the following technical solutions:

[0022] An overhead line protection area boundary safety early warning method is applied in the overhead line protection area boundary safety early warning system in the first aspect, and is executed by an electronic device, and includes the following steps:

[0023] Obtaining image information of a construction area collected by a camera device, wherein the image information includes construction machinery, power lines and vertical poles;

[0024] Performing feature recognition on the image information to obtain construction machinery features, power line features and vertical pole features in the image information;

[0025] Determining a warning area below the boundary based on the power line features and the vertical pole features;

[0026] When the construction machinery features are detected to enter the warning area, determining distance information between the top of the construction machinery features and the boundary;

[0027] Determining working frequencies of a plurality of first infrared emission devices based on the distance information;

[0028] Controlling the plurality of first infrared emission devices to operate at the working frequencies.

[0029] By adopting the technical scheme, the electronic device acquires image information and performs feature recognition on the image information, so that the construction machinery feature, the power line feature and the vertical pole feature in the image information can be recognized. Since the length of the vertical pole is set by a worker as needed and the length of the vertical pole represents the maximum height at which the construction machinery can move below the power line, the size of the warning area is related to the power line itself, and therefore the warning area of the boundary can be determined according to the vertical pole feature and the power line. When the construction machinery enters the warning area, it means that the construction machinery is close to the boundary. At this time, the working frequency of the first infrared emission device is determined according to the distance information from the top of the construction machinery to the boundary. The smaller the distance information is, the closer the construction machinery is to the boundary, and the higher the working frequency needs to be to detect whether the construction machinery has crossed the boundary. The larger the distance information is, the farther the construction machinery is from the boundary, and the lower the working frequency needs to be. Therefore, the appropriate working frequency of the first infrared emission device is determined according to the distance information. After the working frequency is determined, the first infrared emission device works at the determined working frequency, so that the waste of electric energy of the first infrared emission device during working is reduced.

[0030] In another possible implementation manner, the determination of the warning area below the boundary based on the power line and the vertical pole feature includes:

[0031] acquiring positioning information of the power line;

[0032] determining a voltage level of the power line from a preset power distribution map based on the positioning information, the preset power distribution map including distribution positions of power lines and voltage levels of the power lines at each position;

[0033] determining a corresponding segmentation coefficient based on the voltage level;

[0034] equally segmenting the vertical pole feature based on the segmentation coefficient to obtain at least two vertical pole part features;

[0035] determining a length of a single vertical pole part feature;

[0036] determining a region formed by the length from the top end of the vertical pole to the downward direction as the warning area.

[0037] By adopting the technical scheme, the position of the power line can be determined in the preset power distribution map through the positioning information of the power line. Since the preset power distribution map also includes the voltage level of the power line at each position, the voltage level of the power line in the construction area can be determined. Since the required alert area size is different for different voltage levels, after the voltage level is determined, the electronic device can determine the segmentation coefficient, and the vertical rod feature is equally segmented to obtain the length of the single vertical rod feature. The length is the appropriate alert area width determined according to the voltage level of the power line. According to the length and the infrared boundary, the alert area corresponding to the power line can be determined.

[0038] In another possible implementation manner, the determining the working frequency of the plurality of first infrared emission devices based on the distance information comprises:

[0039] determining a preset distance interval in which the distance information is located, the preset distance interval corresponding to a preset working frequency;

[0040] determining the preset working frequency corresponding to the preset distance interval in which the distance information is located as the working frequency of the plurality of first infrared emission devices.

[0041] By adopting the technical scheme, each preset distance interval corresponds to an optimal working frequency, that is, a preset working frequency. By determining the preset distance interval in which the distance information is located, the preset working frequency corresponding to the preset distance interval is determined as the working frequency of the plurality of first infrared emission devices, which is more accurate.

[0042] In another possible implementation manner, when any first infrared receiving device does not receive infrared emitted by a corresponding first infrared emission device, a first detection signal is output. The method further comprises:

[0043] When the first detection signal output by any first infrared receiving device is received, a time point triggered by the first detection signal is determined.

[0044] A picture of the time point is intercepted from the image information. Feature recognition is performed on the picture, and whether the picture includes a construction machinery feature is determined.

[0045] If yes, alarm information is output.

[0046] By adopting the technical scheme, the electronic device receives the first detection signal output by any first infrared receiving device, which indicates that an object blocks the infrared rays, so that the time of triggering the first detection signal is determined, and the corresponding picture of the time is intercepted from the image information, and the picture is subjected to feature recognition, so that it can be known whether the construction machinery feature exists in the picture, that is, it can be known whether the construction machinery blocks the infrared rays to trigger the first detection signal, if the construction machinery feature exists in the picture, it is confirmed that the construction machinery crosses the infrared ray boundary, and the electronic device controls the output of the alarm information at this time, so that the staff can know that the construction machinery crosses the boundary in time, and it is confirmed whether the first detection signal is triggered by the construction machinery in combination with the image information, and the accuracy of the early warning is improved.

[0047] In another possible implementation manner, the method further includes:

[0048] determining a position of the construction machinery feature in the image information, and determining a target infrared emitting device from the plurality of first infrared emitting devices according to the position;

[0049] controlling the target infrared emitting device to work.

[0050] By adopting the technical scheme, the target infrared emitting device is determined according to the position of the construction machinery feature, the target infrared emitting device is the first infrared emitting device corresponding to the position of the construction machinery, the first infrared emitting device other than the target infrared emitting device is not easy to detect whether the construction machinery crosses the boundary, and the degree of relevance with the construction machinery is not high, so that the target infrared emitting device is controlled to work, and the first infrared emitting device other than the target infrared emitting device does not work, thereby further saving the electric energy and reducing the waste of resources.

[0051] In another possible implementation manner, when any second infrared receiving device outputs a second detection signal when the corresponding second infrared emitting device does not receive the infrared rays, the method further includes:

[0052] controlling the loudspeaker device to output first prompt information when the second detection signal triggered by any second infrared receiving device is received.

[0053] By adopting the technical scheme, the electronic device receives the second detection signal triggered by any second infrared receiving device, which indicates that a person enters the construction area between the two groups of vertical rods, so that the electronic device controls the loudspeaker device to output the first prompt information, thereby reminding the person entering the construction area, and further reminding the person entering the construction area to pay attention to the height when using the construction machinery.

[0054] In another possible implementation manner, the method further includes:

[0055] If the electronic device receives the first detection signal sent by any of the first infrared receiving devices, and the preset time length is reached, the second prompt information is output.

[0056] By adopting the technical scheme, the electronic device receives the first detection signal sent by any of the first infrared receiving devices, which indicates that there may be an object blocking the infrared rays. The electronic device detects that the time length of receiving the first detection signal reaches the preset time length, which indicates that the first infrared transmitting device or the first infrared receiving device is abnormal. The electronic device outputs the second prompt information, thereby timely reminding the staff that the first infrared transmitting device or the first infrared receiving device is abnormal.

When the construction machinery enters the warning area, it means that it is close to the boundary. At this time, the distance determination module determines the distance information from the top of the construction machinery to the boundary, and the frequency determination module determines the working frequency of the first infrared emission device. The smaller the distance information is, the closer to the boundary it is, and the higher the working frequency required to detect whether the construction machinery has crossed the boundary is. The larger the distance information is, the farther away from the boundary it is, and the lower the possibility of crossing the boundary is. Therefore, a lower working frequency is required.

[0072] determine a warning area between the plurality of first infrared emission devices and the plurality of first infrared receiving devices, and a region formed by extending the length downward from the top end of the vertical pole.

[0073] In another possible implementation, when the frequency determination module determines the working frequency of the plurality of first infrared emission devices based on the distance information, the frequency determination module is specifically configured to:

[0074] determine a preset distance interval in which the distance information is located, wherein the preset distance interval corresponds to a preset working frequency;

[0075] The preset working frequency corresponding to the preset distance interval where the distance information is located is determined as the working frequency of the plurality of first infrared emission devices.

[0076] In another possible implementation, when any first infrared receiving device does not receive infrared rays emitted by a corresponding first infrared emission device, the device further includes:

[0077] a time point determination module configured to determine a time point triggered by the first detection signal when the first detection signal output by any first infrared receiving device is received;

The size of the warning area is related to the power line itself, so the warning area of the boundary can be determined according to the characteristics of the vertical rod and the power line.

[0120] S104, when the construction machinery feature is detected to enter the warning area, the distance information between the top of the construction machinery feature and the boundary is determined.

[0121] For the embodiment of the present application, after the warning area is determined, if the top of the construction machinery does not enter the warning area, it means that the distance to the boundary is far, and the possibility of crossing the boundary is low, so the first infrared emitter and the first infrared receiver do not need to be turned on. If the top of the construction machinery enters the warning area, it means that the distance to the boundary is close, and the possibility of crossing the boundary is high, so the first infrared emitter and the first infrared receiver need to be turned on. After the construction machinery enters the warning area, the closer the distance to the boundary, the greater the possibility of crossing the boundary, and the more need to strengthen the detection of whether the construction machinery crosses the boundary. Therefore, after detecting that the construction machinery feature enters the warning area, the top of the construction machinery first contacts the boundary, and the position of the boundary is fixed, so the electronic device determines the distance information between the top of the construction machinery feature and the boundary.

[0122] Specifically, after the electronic device determines the warning area, it can know the width of the warning area in the vertical direction. The electronic device can determine the number of pixels occupied by the width according to the image information, and the width of the warning area is represented by the number of pixels. After detecting that the construction machinery feature enters the warning area, the position of the pixel of the top of the construction machinery feature in the warning area is determined, and then the electronic device can determine the number of pixels between the pixel of the top of the construction machinery feature and the boundary in the vertical direction, and the distance information is represented by the number of pixels between the pixel of the top of the construction machinery feature and the boundary in the vertical direction.

[0123] S105, determining the working frequency of the plurality of first infrared emitters based on the distance information.

[0124] For the embodiment of the present application, the closer the distance between the top of the construction machinery feature and the boundary, the greater the need to strengthen the detection of whether the construction machinery feature crosses the boundary, so the first infrared emitter needs to emit infrared rays at a higher working frequency to form a more accurate and timely boundary. The farther the distance between the construction machinery feature and the boundary, the smaller the possibility of crossing the boundary, so it is not necessary to strengthen the detection of whether the construction machinery feature crosses the boundary, and the first infrared emitter can emit infrared rays at a lower working frequency. That is, the distance information is inversely proportional to the working frequency of the first infrared emitter, the smaller the distance information, the higher the required working frequency, so the required working frequency can be determined according to the distance information.

[0125] S106, controlling the plurality of first infrared emission devices to operate according to the working frequency.

[0126] For the embodiment of the application, the electronic device can be connected with the first infrared emission device through a wire or wirelessly. After the working frequency is determined, the electronic device generates a control signal according to the working frequency, and then sends the control signal to the first infrared emission device, so that the first infrared emission device operates according to the determined working frequency.

[0127] Referring to Figure 1 and Figure 2 The second infrared emission device 23 and the second infrared receiving device 24 are fixedly connected to the vertical poles 1 at both ends of each group of vertical poles 1. The orientations of the second infrared emission device 23 and the second infrared receiving device 24 on a single vertical pole 1 are 90 degrees, respectively facing the vertical pole 1 at the other end or the vertical pole 1 at the same end from the other group of vertical poles 1. The second infrared emission device 23 on each vertical pole 1 corresponds to the second infrared receiving device 24 on the adjacent vertical pole 1, and the infrared emitted by the second infrared emission device 23 forms a rectangular boundary around the construction area. When an object blocks the infrared emitted by the second infrared emission device 23, it means that an object has crossed the boundary and entered the construction area, so that it can be detected whether a person has entered the construction area. When the second infrared receiving device 24 does not receive the infrared emitted by the corresponding second infrared emission device 23, the second infrared receiving device 24 outputs a second detection signal. The overhead line protection area boundary safety early warning system in the embodiment of the application further includes a loudspeaker device 5, which can be arranged near the construction area to output voice to the construction area. The loudspeaker device 5 and the electronic device 4 can be connected by a wire or wirelessly. When the electronic device 4 receives the second detection signal, it means that a person has entered the construction area, and attention should be paid to the height of the construction machinery not exceeding the specified height during construction. The electronic device 4 controls the loudspeaker device 5 to output first prompt information at this time, for example, voice prompt information such as "You have entered the construction area, please pay attention to the height of the construction machinery not exceeding the specified height".

[0128] The embodiment of the application provides an overhead line protection area boundary safety early warning method, which is applied to the overhead line protection area boundary safety early warning system in the embodiment of the application, as shown in Figure 4 The method comprises steps S101, S102, S103, S104, S105 and S106, wherein,

[0129] S101, acquiring image information of the construction area collected by the camera device.

[0130] The image information includes construction machinery, power lines, and poles.

[0131] In this embodiment of the application, the camera device is set at a position that can capture images of the construction area, power lines, and poles. After the camera device captures image information within the construction area, the electronic device can obtain the image information and thus know the specific situation within the construction area.

[0132] S102, perform feature recognition on the image information to obtain the features of construction machinery, power lines and poles in the image information.

[0133] In this embodiment, the electronic device can input image information into a trained network model for feature recognition, thereby identifying construction machinery features, power line features, and pole features in the image information. Specifically, the network model can be a convolutional neural network model, a recurrent neural network model, or other types of network models, which are not limited here. After obtaining the construction machinery features, power line features, and pole features, the electronic device can determine the relative positions of the construction machinery and power lines, and also the relative positions of the construction machinery features and pole features.

[0134] S103, determine the warning zone below the boundary based on the characteristics of power lines and poles.

[0135] In this embodiment of the application, the length of the vertical pole is set by the workers according to the required height of the boundary, and the length of the vertical pole, i.e. the position of the boundary, represents the maximum height that the construction machinery can move under the power line. The size of the warning area is related to the power line itself. Therefore, the warning area of ​​the boundary can be determined based on the characteristics of the vertical pole and the power line.

[0136] S104, When a construction machinery feature is detected to have entered the warning area, determine the distance information between the top of the construction machinery feature and the boundary.

[0137] In this embodiment, after determining the warning area, if the top of the construction machinery does not enter the warning area, it indicates that the distance to the boundary is relatively far, and the possibility of crossing the boundary is low. Therefore, it is not necessary to activate the first infrared transmitter and the first infrared receiver. If the top of the construction machinery enters the warning area, it indicates that the distance to the boundary is relatively close, and the possibility of crossing the boundary is high. Therefore, it is necessary to activate the first infrared transmitter and the first infrared receiver. After the construction machinery enters the warning area, the closer it is to the boundary, the greater the possibility of crossing the boundary, and the more important it is to strengthen the detection of whether the construction machinery has crossed the boundary. Therefore, after detecting that the construction machinery feature has entered the warning area, the top of the construction machinery first contacts the boundary, and the position of the boundary is fixed. Therefore, the electronic device determines the distance information between the top of the construction machinery feature and the boundary.

[0138] Specifically, the electronic device can determine the width of the warning area in the vertical direction after determining the warning area, and the electronic device can determine the number of pixels occupied by the width according to the image information, and the number of pixels represents the width of the warning area. After detecting that the construction machinery feature enters the warning area, the position of the pixel at the top of the construction machinery feature in the warning area is determined, and then the electronic device can determine the number of pixels between the pixel at the top of the construction machinery feature and the boundary in the vertical direction, and the number of pixels between the pixel at the top of the construction machinery feature and the boundary in the vertical direction represents the distance information.

[0139] In S105, the working frequency of the plurality of first infrared emitting devices is determined based on the distance information.

[0140] For the embodiment of the present application, the closer the distance from the top of the construction machinery feature to the boundary, the more need to strengthen the detection of whether the construction machinery feature crosses the boundary, and therefore the first infrared emitting device needs to emit infrared rays at a higher working frequency, so as to form a boundary that is more accurate and timely in detection. The farther the distance from the construction machinery feature to the boundary, the less likely it is to cross the boundary, and therefore there is no need to strengthen the detection of whether the construction machinery feature crosses the boundary, and therefore the first infrared emitting device can emit infrared rays at a lower working frequency. That is, the distance information is inversely proportional to the working frequency of the first infrared emitting device, and the smaller the distance information, the higher the required working frequency, and therefore the required working frequency can be determined according to the distance information.

[0141] In S106, the plurality of first infrared emitting devices are controlled to operate at the working frequency.

[0142] For the embodiment of the present application, the electronic device can be connected to the first infrared emitting device through a wire or wirelessly, and after the working frequency is determined, the electronic device generates a control signal according to the working frequency, and then sends the control signal to the first infrared emitting device, so that the first infrared emitting device operates at the determined working frequency.

[0143] In one possible implementation of the embodiment of the present application, the warning area below the boundary is determined based on the power line and the vertical pole feature in step S103, and specifically includes steps S1031 (not shown in the figure), S1032 (not shown in the figure), S1033 (not shown in the figure), S1034 (not shown in the figure), S1035 (not shown in the figure), and S1036 (not shown in the figure), wherein,

[0144] In S1031, the positioning information of the power line is obtained.

[0145] For the embodiment of the present application, the worker can install a GPS positioning device at positions such as the construction area and the power line of the construction area, so as to obtain the positioning information of the power line of the construction area.

[0146] S1032, determine the voltage level of the power line from the preset power distribution map based on the positioning information.

[0147] The preset power distribution map includes the distribution position of the power line and the voltage level of the power line at each position.

[0148] For the embodiment of the present application, the power distribution map includes the geographical distribution of the power line in a certain area, and includes the voltage level of each power line. The staff can pre-store the power distribution map into the electronic device, and after determining the positioning information of the power line, find the power line at the construction area in the preset power distribution map according to the positioning information, so as to determine the voltage level of the power line at the construction area.

[0149] For example, the voltage level includes three levels, respectively, the 35-110 kilovolt voltage level is level one, the minimum safe distance of the construction machinery to the power line is 6 meters; the 220 kilovolt voltage level is level two, the minimum safe distance of the construction machinery to the power line is 7 meters; the 500 kilovolt voltage level is level three, the minimum safe distance of the construction machinery to the power line is 8.5 meters. Assuming that the voltage level of the power line at the construction area is level two.

[0150] S1033, determine the corresponding segmentation coefficient based on the voltage level.

[0151] For the embodiment of the present application, the corresponding segmentation coefficient of each voltage level can be pre-stored in the electronic device, so that the electronic device can determine the segmentation coefficient according to the corresponding relationship between the voltage level and the segmentation coefficient after determining that the voltage level of the power line at the construction area is level two. Assuming that the segmentation coefficient corresponding to level one is 5, that is, the vertical rod feature is equally divided into 5 parts; the segmentation coefficient corresponding to level two is 4, that is, the vertical rod feature is equally divided into 4 parts; the segmentation coefficient corresponding to level three is 3, that is, the vertical rod feature is equally divided into 3 parts. The electronic device determines that the segmentation coefficient of level two is 4.

[0152] S1034, equally divide the vertical rod feature based on the segmentation coefficient to obtain at least two vertical rod partial features.

[0153] For the embodiment of the present application, the electronic device equally divides the vertical rod feature into 4 parts after obtaining the vertical rod feature. Specifically, the number of pixels of the vertical rod feature in the vertical direction can be determined, and then the division points are determined according to the segmentation coefficient 4, and the vertical rod feature is equally divided.

[0154] S1035, determine the length of a single vertical rod partial feature.

[0155] For the embodiment of the present application, the electronic device equally divides the vertical rod feature to obtain a single vertical rod part feature, and the electronic device can determine the number of pixels of the vertical rod part feature in the vertical direction, and determine the number of pixels as the length of the single vertical rod part feature.

[0156] S1036, the area formed by the multiple first infrared emitting devices and the multiple first infrared receiving devices and the length extending downward from the top end of the vertical rod is determined as the warning area.

[0157] For the embodiment of the present application, after the electronic device determines the length of the single vertical rod part feature, the electronic device can determine the warning area according to the length of the vertical rod part feature starting from the position of the first infrared emitting device emitting infrared rays.

[0158] In one possible implementation of the embodiment of the present application, the step S105 of determining the working frequency of the multiple first infrared emitting devices based on the distance information specifically includes a step S1051 (not shown in the figure) and a step S1052 (not shown in the figure), wherein,

[0159] S1051, a preset distance interval in which the distance information is located is determined.

[0160] The preset distance interval corresponds to a preset working frequency.

[0161] For the embodiment of the present application, the distance information can be represented by the number of pixels, the smaller the distance information is, the closer the distance to the boundary is, and the higher the working frequency required by the first infrared emitting device is. Therefore, the electronic device pre-stores multiple preset distance intervals, assuming that there are three preset distance intervals, which are (0, 100], (100, 200] and (200, 300]; the preset working frequencies corresponding to the above three preset distance intervals are 1000 infrared rays emitted per second by the first infrared emitting device, 600 infrared rays emitted per second by the first infrared emitting device and 200 infrared rays emitted per second by the first infrared emitting device, respectively. Assuming that the distance information determined by the electronic device is 70 pixels, the electronic device can determine that the preset depth interval in which the depth is located is (0, 100].

[0162] S1052, the preset working frequency corresponding to the preset distance interval in which the distance information is located is determined as the working frequency of the multiple first infrared emitting devices.

[0163] For the embodiment of the present application, taking the step S1051 as an example, after the electronic device determines that the interval in which the distance information is located is (0, 100], the electronic device can directly determine 1000 infrared rays emitted per second corresponding to the interval as the working frequency of the first infrared emitting device.

[0164] In other embodiments, since the distance information is negatively correlated with the working frequency, a linear function relationship, for example, a linear function relationship y = -6x + 2000, can also be pre-stored in the electronic device, where y is the determined working frequency, -6 is a proportional coefficient, x is the distance information (pixel quantity), and 2000 is an intercept reference value for calculating the working frequency. The distance information is substituted into the above linear function relationship to obtain the working frequency required by the first infrared emitting device.

[0165] In one possible implementation of the embodiments of the present application, when any first infrared receiving device does not receive infrared rays emitted by the corresponding first infrared emitting device, a first detection signal is output, and the method further includes steps S107 (not shown in the figure), S108 (not shown in the figure), and S109 (not shown in the figure), where step S107 can be executed after step S101, and steps S108 and S109 can be executed after step S107.

[0166] S107, when the first detection signal output by any first infrared receiving device is received, the time when the first detection signal is triggered is determined.

[0167] For the embodiments of the present application, if any first infrared receiving device does not receive infrared rays, it means that an object blocks the infrared rays, so the first infrared receiving device triggers the first detection signal. The electronic device is connected to the first infrared receiving device through a wire or wirelessly, so the electronic device can know that an object has crossed the boundary formed by the infrared rays when the first detection signal is received. After receiving the first detection signal, the electronic device can determine the time when the first detection signal is received according to a local clock chip or a cloud server.

[0168] S108, a picture at the time is intercepted from the image information, and feature recognition is performed on the picture to determine whether there is a construction machinery feature in the picture.

[0169] For the embodiments of the present application, when the electronic device determines the time when the first detection signal is received, since the electronic device acquires image information captured by the camera in real time, the picture at the time can be determined from the image information. The electronic device inputs the picture into a trained network model for feature recognition, so as to determine whether there is a construction machinery feature in the picture.

[0170] S109, if there is, an alarm information is output.

[0171] For the embodiment of the present application, the electronic device determines that the construction machinery feature exists in the picture, which means that the construction machinery feature crosses the boundary and is not other objects that trigger the first detection signal by mistake. Therefore, the electronic device can control the loudspeaker device in the construction area to output the voice prompt information of "construction machinery height is too high", and can also send the SMS text information of "construction machinery height is too high" to the terminal device corresponding to the staff. Further, the alarm lamp can also be arranged on the vertical rod, and when it is detected that the construction machinery feature exists in the picture, the alarm lamp is controlled to light up or flash to alarm.

[0172] If the electronic device determines that the construction machinery feature does not exist in the picture, but other objects exist, it means that the first detection signal is triggered by mistake, and therefore no alarm information needs to be output.

[0173] In a possible implementation manner of the embodiment of the present application, the method further includes a step S110 (not shown in the figure) and a step S111 (not shown in the figure), wherein the step S110 can be executed after the step S102, and the step S111 can be executed after the step S110.

[0174] S110, determining the position of the construction machinery feature in the image information, and determining the target infrared emission device from the plurality of first infrared emission devices according to the position.

[0175] For the embodiment of the present application, after the electronic device obtains the construction machinery feature in the construction area through feature recognition, the position of the construction machinery feature in the image information is determined. Since the power vertical rod feature is recognized, the distance of the construction machinery to each vertical rod is determined, and the nearest one or several vertical rods are determined. The nearest one or several first infrared emission devices are the infrared emission devices that can perform the out-of-boundary detection on the construction machinery height. Other first infrared emission devices are far away from the construction machinery, and are not convenient or cannot perform the out-of-boundary detection on the construction machinery feature. Therefore, the first infrared emission devices on the nearest one or several vertical rods are the target infrared emission devices.

[0176] S111, controlling the target infrared emission device to work.

[0177] For the embodiment of the present application, after the electronic device determines the target infrared emission device, a control signal is sent to the target infrared emission device, so as to control the target infrared emission device to work. Other first infrared emission devices are not convenient or cannot perform the out-of-boundary detection on the construction machinery, and therefore the other first infrared emission devices do not work, thereby improving the detection effect.

[0178] In a possible implementation manner of the embodiment of the present application, when any second infrared receiving device does not receive the infrared emitted by the corresponding second infrared emission device, the second detection signal is output. The method further includes a step S112 (not shown in the figure), wherein

[0179] S112, when receiving the second detection signal triggered by any second infrared receiving device, controlling the loudspeaker device to output the first prompt information.

[0180] For the embodiment of the application, when the electronic device receives the second detection signal triggered by any second infrared receiving device, it indicates that a person has entered the construction area and needs to pay attention to the height of the construction machinery during construction. Therefore, the electronic device controls the loudspeaker device to voice broadcast the voice prompt information "You have entered the construction area, please pay attention to the height of the construction machinery not to exceed the specified height".

[0181] In one possible implementation of the embodiment of the application, the method further includes step S113 (not shown in the figure), which can be executed before step S101, after step S101, or simultaneously with step S101, wherein,

[0182] S113, if the electronic device receives the first detection signal sent by any first infrared receiving device and reaches the preset time length, the second prompt information is output.

[0183] For the embodiment of the application, when the electronic device receives the first detection signal sent by any first infrared receiving device, it indicates that an object may block the infrared rays, but it is also possible that the corresponding first infrared emitting device is damaged and does not emit infrared rays. Therefore, a preset time length is set, assuming that the preset time length is 10 seconds. If the electronic device receives the first detection signal and still receives the first detection signal after 10 seconds, the electronic device can determine that the corresponding first infrared emitting device of the first infrared receiving device is damaged. Therefore, the electronic device outputs the second prompt information. Specifically, the electronic device can send an SMS prompt information "the first infrared emitting device is damaged, please repair in time" to the terminal device corresponding to the worker. Further, each first infrared emitting device can be numbered to determine the source of the first detection signal, and the second prompt information can be output according to the number, so that the worker can more intuitively know the damaged first infrared emitting device.
