[0021] The present invention is further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0022] With the development of society, civil engineering, construction, power and other engineering construction are in full swing. Sometimes, in order to reduce the impact on people's daily life or to improve the efficiency of construction, some construction needs to be carried out at night. Therefore, it is necessary to supervise the night construction, especially to give safety warnings for night construction, such as Figure 1 As shown, a first aspect of an embodiment of the present invention provides a method for nighttime construction safety warning, comprising the following steps:

[0023] Step 101, identifying a nighttime construction area of ​​the area to be photographed based on a nighttime image of the area to be photographed.

[0024] Equipment located in a ground station, a ground data center, a satellite with computing capabilities, etc. can supervise night construction and can monitor night images of one or more areas in real time or periodically, wherein the area to be monitored is the area to be photographed, that is, the equipment can obtain night images of the area to be photographed periodically or in real time, and identify the night construction area of ​​the area to be photographed based on the acquired night images. Since the night images are monitored, in some embodiments, identifying the night construction area of ​​the area to be photographed includes: obtaining a night image of the area to be photographed within a set night shooting time; performing brightness recognition on the night image, and determining the night construction area from the area to be photographed based on the brightness value.

[0025] For example, the set night shooting time can be 6 pm to 6 am, or 5 pm to 5 am, etc., which can be determined according to the geographical area where the area to be photographed is located, the shooting season, etc.

[0026] There are many ways to obtain night images of the area to be photographed. If one or more cameras are configured in the area to be photographed, equipment located in a ground station, a ground data center, a satellite with computing capabilities, etc. can communicate with the camera to obtain night images of the area to be photographed.

[0027] Alternatively, in some embodiments, obtaining a night image of the area to be photographed includes: determining a twilight orbit satellite that is closest to the area to be photographed at a set night shooting time as a first twilight orbit satellite to be photographed; sending a photo request instruction to the first twilight orbit satellite, and receiving a night image of the area to be photographed obtained by the first twilight orbit satellite.

[0028] The twilight orbit is a special sun-synchronous orbit. When the satellite passes the equator, the ground time is the local sunrise and sunset respectively. The orbital plane and the earth's twilight line always overlap approximately. The satellite running on the twilight orbit is the twilight orbit satellite. Therefore, according to the set night shooting time and the geographical location of the area to be photographed, the twilight orbit satellite closest to the area to be photographed at the set night shooting time can be determined, that is, the first twilight orbit satellite. In this way, the device located in the ground station, the ground data center, or a satellite with computing power can send a photo request instruction to the first twilight orbit satellite. In this way, the first twilight orbit satellite can take a night image of the area to be photographed and return it to the device. Thus, the device can receive the night image of the area to be photographed obtained by the first twilight orbit satellite, and then perform brightness recognition on the night image, and determine the night construction area from the area to be photographed according to the brightness value.

[0029] Usually, searchlights are turned on at construction sites at night. The brightness of the searchlights is significantly higher than the brightness of lights in residential areas such as street lights and lighting. Therefore, a brightness threshold can be determined, for example: a first set brightness threshold, so that the area in the area to be photographed with a brightness value greater than the first set brightness threshold is determined as a night construction area; and the first geographic location information of the night construction area is determined.

[0030] The first geographical location information of the nighttime construction area may be obtained in advance, for example, by obtaining the reported first geographical location information of the nighttime construction area through network communication.

[0031] Generally, the construction area is clearly visible during the day and has a certain overlap with the nighttime construction area. Therefore, in some embodiments, determining the nighttime construction area from the area to be photographed according to the brightness value includes: identifying the construction area of ​​the area to be photographed according to the daytime image of the area to be photographed, wherein the daytime image is obtained by dispatching an optical multispectral satellite; embedding the geographic location coordinates of the construction area into the nighttime image, and identifying the brightness value of the construction area in the nighttime image; determining the area in the construction area with a brightness value greater than a second set brightness threshold as the nighttime construction area. The second set brightness threshold may be equal to or unequal to the first set brightness threshold.

[0032] During the day, the optical multispectral satellite can be dispatched to take images of the area to be photographed. In this way, since the image is clear, the construction area can be clearly identified, and the geographical location coordinates of the construction area can be obtained, which are nested in the night image of the area to be photographed, and the brightness of the night image is identified. The area in the construction area with a brightness value greater than the second set brightness threshold is determined as the night construction area. At the same time, the geographical location coordinates of the night construction area, i.e., the first geographical location information, are also obtained.

[0033] Step 102: When the area to be photographed includes a high-voltage transmission line, determine the current distance between the high-voltage transmission line and the nighttime construction area.

[0034] The transmission line is achieved by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. It is an infrastructure to ensure the normal operation of factories and life. Among them, the transmission line includes: high-voltage transmission lines and civil transmission lines. The electricity generated by the power plant is not only used by people nearby, but also transmitted to far away places to meet more needs. This electricity cannot be transmitted directly through ordinary wires, but must be transmitted by high-voltage transmission lines. Therefore, high-voltage transmission lines usually refer to transmission lines that transmit voltages above 10kV. When the electricity is transmitted to the place where it is used, the voltage must be lowered before it can be used. At this time, it is transmitted through civil transmission lines.

[0035] In order to ensure construction safety and the safe operation of power lines, the high-voltage transmission line must be far away from the construction area. Therefore, it is necessary to determine the current distance between the high-voltage transmission line and the nighttime construction area. Since the first geographic location information of the nighttime construction area has been determined when the nighttime construction area of ​​the area to be photographed is identified, in some embodiments, determining the current distance between the high-voltage transmission line and the nighttime construction area includes: determining the second geographic location information of the high-voltage transmission line based on the coordinate information of each transmission line tower in the area to be photographed; and obtaining the current distance between the high-voltage transmission line and the nighttime construction area based on the first geographic location information of the nighttime construction area and the second geographic location information of the high-voltage transmission line.

[0036] The equipment located in the ground station, ground data center, or a satellite with computing power can obtain the information of each transmission line tower in the area to be photographed, so as to determine whether there is a tower of a high-voltage transmission line. If so, it can be determined that the area to be photographed includes a high-voltage transmission line, and the second geographical location information of the high-voltage transmission line can be determined based on the coordinate information of the high-voltage transmission line tower. Thus, the current distance between the high-voltage transmission line and the nighttime construction area can be obtained based on the first geographical location information and the second geographical location information.

[0037] The geographical area of ​​the transmission line may be preset or obtained by identifying the towers through satellite remote sensing images. In some embodiments, determining the second geographical location information of the high-voltage transmission line further includes: identifying each transmission line tower in the area to be photographed through satellite remote sensing images, and obtaining corresponding coordinate information, thereby determining the second geographical location information of the high-voltage transmission line based on the coordinate information.

[0038] Step 103: When the current distance is less than the set distance threshold, a circuit safety warning for nighttime construction is issued.

[0039] The "Detailed Rules for the Implementation of the Electric Power Facility Protection Ordinance" have determined the horizontal safe distance between the edge of each voltage conductor and the building when calculating the maximum wind deviation of the conductor. Therefore, the corresponding set distance threshold can be determined according to the current voltage of the high-voltage transmission line. In this way, when the current distance is less than the set distance threshold, a circuit safety warning for night construction will be issued.

[0040] Of course, there are many ways to issue circuit safety warnings during nighttime construction, which may include: sending high-voltage warning information to one or more terminals corresponding to the construction unit, the municipal supervision terminal, the municipal safety agency terminal, etc.

[0041] It can be seen that in the embodiment of the present invention, the night construction area is identified through the night image of the area to be photographed, and when the area to be photographed includes a high-voltage transmission line, if the current distance between the high-voltage transmission line and the night construction area is less than the set distance threshold, a night construction circuit safety warning is issued. In this way, not only can the night construction area be quickly determined, but also the safety hazards between the night construction and the transmission line can be timely checked, thereby improving the safety of night construction and reducing the probability of safety accidents. In addition, dawn and dusk orbit satellites, optical multispectral satellites, etc. can be dispatched to capture images of the area to be photographed, so that the image is clear and accurate, further ensuring the accuracy of the high-voltage electricity warning during night construction.

[0042] The operation process is summarized into a specific embodiment below, and an example is given to illustrate the nighttime construction safety warning process provided by the embodiment of the present invention.

[0043] In one embodiment of the present invention, the ground station stores a first set brightness threshold. The set night shooting time is 6 pm to 6 am. Figure 2 As shown, the method for nighttime construction safety warning comprises the following steps:

[0044] Step 201, when the current time is between 6 pm and 6 am, the ground station determines the twilight orbit satellite that is closest to the area to be photographed at the current time as the first twilight orbit satellite to be photographed.

[0045] Step 202: The ground station sends a photo request instruction to the first dawn-dusk orbit satellite, and receives a night image of the area to be photographed obtained by the first dawn-dusk orbit satellite.

[0046] Step 203: The ground station performs brightness recognition on the night image, and determines the area in the area to be photographed whose brightness value is greater than a first set brightness threshold as a night construction area.

[0047] Step 204: The ground station determines first geographical location information of the nighttime construction area based on known geographical location information.

[0048] Step 205, determine whether the area to be photographed includes a high-voltage transmission line. If so, execute step 206, otherwise, the process ends.

[0049] Step 206: The ground station determines second geographical location information of the high-voltage transmission line based on known geographical location information of the transmission line.

[0050] Step 207: The ground station obtains the current distance between the high-voltage transmission line and the nighttime construction area based on the first geographical location information and the second geographical location information.

[0051] Step 208, determine whether the current distance is less than a set distance threshold matching the high-voltage transmission line. If so, execute step 209, otherwise, the process ends.

[0052] Step 209: The ground station sends high voltage warning information to the terminal corresponding to the construction unit and the terminal corresponding to the municipal supervision.

[0053] In this embodiment, the dawn-dusk orbit satellite can be dispatched to obtain accurate night images of the area to be photographed, identify the night construction area, and when the area to be photographed includes a high-voltage transmission line, if the current distance between the high-voltage transmission line and the night construction area is less than the set distance threshold, a night construction circuit safety warning is issued. In this way, not only can the night construction area be quickly determined, but also the safety hazards between the night construction and the transmission line can be promptly checked, thereby improving the safety of night construction and reducing the chance of safety accidents.

[0054] In one embodiment of the present invention, the ground data center stores the second set brightness threshold. The set night shooting time is 6 pm to 6 am. Figure 3 The method for nighttime construction safety warning comprises the following steps:

[0055] Step 301, when the current time is between 6 pm and 6 am, the ground data center determines the twilight orbit satellite that is closest to the area to be photographed at the current time as the first twilight orbit satellite to be photographed.

[0056] Step 302: The ground data center sends a photo request instruction to the first dawn-dusk orbit satellite, and receives a night image of the area to be photographed obtained by the first dawn-dusk orbit satellite.

[0057] Step 303: The ground data center identifies the construction area of ​​the area to be photographed based on the daytime image of the area to be photographed, wherein the daytime image is acquired by dispatching an optical multispectral satellite.

[0058] Step 304: The ground data center embeds the geographical location coordinates of the construction area into the night image, and identifies the brightness value of the construction area in the night image.

[0059] Step 305: The ground data center determines the area in the construction area whose brightness value is greater than the second set brightness threshold as a nighttime construction area, and determines the first geographic location information of the nighttime construction area based on the nested geographic location coordinates.

[0060] Step 306, determine whether the area to be photographed includes a high-voltage transmission line? If so, execute step 307, otherwise, the process ends.

[0061] Step 307: The ground data center determines the second geographical location information of the high-voltage transmission line based on the coordinate information of each transmission line tower in the area to be photographed, wherein the coordinate information of the transmission line tower is obtained by identifying each transmission line tower in the area to be photographed through satellite remote sensing images.

[0062] Step 308: The ground data center obtains the current distance between the high-voltage transmission line and the night construction area based on the first geographic location information and the second geographic location information.

[0063] Step 309, determine whether the current distance is less than a set distance threshold matching the high-voltage transmission line. If so, execute step 310, otherwise, the process ends.

[0064] Step 310: The ground data center sends high voltage electricity warning information to the terminal corresponding to the construction unit and the terminal corresponding to the fire department.

[0065] In this embodiment, the dawn and dusk orbit satellite can be dispatched to obtain accurate night images of the area to be photographed, identify the night construction area, and when the area to be photographed includes a high-voltage transmission line, determine the current distance between the high-voltage transmission line and the night construction area through satellite remote sensing images. When the current distance is less than the set distance threshold, a night construction circuit safety warning is issued. In this way, not only can the night construction area be quickly determined, but also the safety hazards between the night construction and the transmission line can be promptly checked, thereby improving the safety of night construction, reducing the probability of safety accidents, and further ensuring the accuracy of high-voltage electricity warnings during night construction.

[0066] According to the above-mentioned process of nighttime construction safety warning, a device for nighttime construction safety warning can be constructed. Figure 4 The device for nighttime construction safety warning provided by the embodiment of the present invention can be applied to equipment in a ground station, a ground data center, or a satellite with computing capabilities, etc. Figure 4 As shown, the device 400 includes: a nighttime identification module 410, a distance determination module 420 and a circuit warning module 430.

[0069] The circuit warning module 430 is configured to issue a circuit safety warning for nighttime construction when the current distance is less than a set distance threshold.

[0070] In some embodiments, the night identification module 410 includes:

[0071] The image acquisition unit is configured to acquire a night image of the area to be photographed within a set night shooting time.

[0075] In some embodiments, the brightness recognition unit is specifically configured to identify the construction area of ​​the area to be photographed based on the daytime image of the area to be photographed, wherein the daytime image is acquired by dispatching an optical multispectral satellite; embed the geographic location coordinates of the construction area into the nighttime image, and identify the brightness value of the construction area in the nighttime image; and determine the area in the construction area where the brightness value is greater than a second set brightness threshold as a nighttime construction area.

[0076] In some embodiments, the distance determination module 420 includes:

[0077] A first determining unit is configured to determine second geographical location information of the high-voltage transmission line according to coordinate information of each transmission line tower in the area to be photographed;

[0078] The second determining unit is configured to obtain a current distance between the high-voltage transmission line and the nighttime construction area based on the first geographical location information of the nighttime construction area and the second geographical location information of the high-voltage transmission line.

[0079] In some embodiments, the first determination unit is further configured to identify each transmission line tower in the area to be photographed through satellite remote sensing images and obtain corresponding coordinate information.

[0080] In some embodiments, the circuit warning module 430 is specifically configured to send high-voltage electricity warning information to one or more of the terminals corresponding to the construction unit, the terminals corresponding to the municipal supervision, the terminals corresponding to the municipal safety agency, etc.

[0081] The following example illustrates the safety warning process of the nighttime construction safety warning device provided by the embodiment of the present invention.

[0082] The safety warning device for nighttime construction can be applied to equipment in ground stations, ground data centers, or satellites with computing capabilities, etc. Figure 5 As shown, the device 400 includes: a nighttime identification module 410, a distance determination module 420 and a circuit warning module 430. The nighttime identification module 410 includes: an image acquisition unit 411 and a brightness identification unit 412, and the distance determination module 420 includes: a first determination unit 421 and a second determination unit 422.

[0083] When the current time is between 6pm and 6am, the image acquisition unit 411 in the night recognition module 410 determines the dawn-dusk orbit satellite that is closest to the area to be photographed at the current time as the first dawn-dusk orbit satellite to be photographed, and after sending a photographing request instruction to the first dawn-dusk orbit satellite, receives the night image of the area to be photographed acquired by the first dawn-dusk orbit satellite. In this way, the brightness recognition unit 412 can identify the construction area of ​​the area to be photographed based on the daytime image of the area to be photographed, wherein the daytime image is acquired by dispatching an optical multispectral satellite, and then, the geographical location coordinates of the construction area are nested in the nighttime image, and the brightness value in the construction area in the nighttime image is identified, and the area in the construction area with a brightness value greater than the second set brightness threshold is determined as the nighttime construction area, and then the first geographical location information of the nighttime construction area is determined based on the nested geographical location coordinates.

[0084] In the case where the area to be photographed includes a high-voltage transmission line, the first determination unit 421 in the distance determination module 420 determines the second geographical location information of the high-voltage transmission line based on the coordinate information of each transmission line tower in the area to be photographed, wherein the coordinate information of the transmission line tower is obtained by identifying each transmission line tower in the area to be photographed through a satellite remote sensing image. In this way, the second determination unit 422 can obtain the current distance between the high-voltage transmission line and the nighttime construction area based on the first geographical location information and the second geographical location information.

[0085] When the current distance is less than the set distance threshold that matches the high-voltage transmission line, the circuit warning module 430 sends high-voltage electricity warning information to the terminal corresponding to the construction unit and the terminal corresponding to the fire department.

[0086] It can be seen that in the embodiment of the present invention, the device for night construction safety warning can dispatch the dawn and dusk orbit satellite to obtain accurate night images of the area to be photographed, identify the night construction area, and when the area to be photographed includes high-voltage transmission lines, determine the current distance between the high-voltage transmission lines and the night construction area through satellite remote sensing images. When the current distance is less than the set distance threshold, a night construction circuit safety warning is issued. In this way, not only can the night construction area be quickly determined, but also the safety hazards between the night construction and the transmission lines can be promptly checked, thereby improving the safety of night construction, reducing the probability of safety accidents, and further ensuring the accuracy of high-voltage electricity warnings during night construction.
