[0039] Figure 1 The structure of the device for identifying construction personnel in an embodiment of the present application is schematically shown. As shown in the figure, Figure 1 In the embodiments of the present application, a device for identifying construction personnel is provided, which is applied to construction equipment including a door. The device can include: a door state detection unit 102 for detecting the opening and closing state of the door; a personnel detection unit 104 for detecting whether there is personnel in the construction equipment; an image acquisition unit 106 for acquiring the image in the construction equipment; and a controller 108 electrically connected with the door state detection unit 102, the personnel detection unit 104 and the image acquisition unit 106. The controller 108 is configured to: obtain the door state information detected by the door state detection unit 102 and the personnel state information detected by the personnel detection unit 104; obtain the target moment when the door state information and the personnel state information change from a first state to a second state and the duration of the second state, wherein the first state is that the door state information is in a closed state and the personnel state information is that there is personnel, and the second state is that the door state information is in an open state and the personnel state information is that there is no personnel; in the case that the duration reaches a preset duration, obtain the target image acquired by the image acquisition unit 106 before the target moment; and identify the target construction personnel according to the target image, wherein the target construction personnel is the construction personnel who last left the construction equipment and did not close the door.

[0040] It can be understood that the door state detection unit 102 is a detection device or apparatus for detecting the opening and closing state of the door of the construction equipment, which can include but is not limited to a door closed to position detection sensor or a door closed detection switch, etc. The personnel detection unit 104 is a detection device or apparatus for detecting whether there is a person in the construction equipment, which can include but is not limited to an infrared sensor or a weight sensor, etc. The image acquisition unit 106 is a device or apparatus for acquiring images in the construction equipment, which can include but is not limited to a camera, etc. The controller 108 can be connected to the door state detection unit 102, the personnel detection unit 104 and the image acquisition unit 106 in a wired or wireless manner. The door state information is the state information of the opening and closing state of the door of the construction equipment. The personnel state information is the state information of whether there is a person in the construction equipment. The first state is that the door state information is in a closed state and the personnel state information is in a state of a person existing, that is, the door of the construction equipment is in a closed state and at the same time there is a person in the construction equipment. The second state is that the door state information is in an open state and the personnel state information is in a state of no person existing, that is, the door of the construction equipment is in an open state and there is no person in the construction equipment. The target time is the time when the first state changes to the second state. The duration of the second state is the length of time that the second state lasts after the first state changes to the second state. The preset duration is the preset duration of the second state, for example, 3 minutes or 5 minutes, which can be set according to actual conditions. It can be understood that if the duration of the second state reaches the preset duration, it can be basically confirmed that the construction personnel has indeed left the construction equipment and the construction personnel has not closed the door. The target image is the image information acquired by the image acquisition unit 106 before the target time, which usually includes the target construction personnel. It can be understood that the target image can record the face information and / or the shape information sufficient to identify the identity of the construction personnel of the construction personnel who last left the construction equipment and did not close the door. The target construction personnel is the construction personnel who last left the construction equipment and did not close the door. It can be understood that the number of target construction personnel can be one or more.

[0041] Specifically, the controller 108 can acquire the door state information detected by the door state detection unit 102 and the personnel state information detected by the personnel detection unit 104, and determine when the door state information and the personnel state information change from a first state (i.e., the door state information is in a closed state and the personnel state information is that there is a person) to a second state (the door state information is in an open state and the personnel state information is that there is no person). At this time, the target time point can be determined, i.e., the target time point at which the door state information and the personnel state information change from the first state to the second state. After that, the controller 108 can continue to acquire the door state information and the personnel state information, so as to acquire the duration of the second state after the first state changes to the second state, and compare the duration with a preset duration. When the duration reaches the preset duration, the controller 108 can acquire a target image before the target time point, which can be a period of time before the target time point, for example, 3 seconds before the target time point, i.e., the target image can be an image collected by the image collection unit 106 3 seconds before the target time point. After acquiring the target image, the controller 108 can identify the specific identity of the target construction worker according to the target image, for example, by comparing the face in the target image with the face information of all construction workers collected and stored in advance, so as to determine the identity information of the target construction worker.

[0042] The above device for identifying construction workers can acquire the door state information detected by the door state detection unit 102 and the personnel state information detected by the personnel detection unit 104, and acquire the target time point at which the door state information and the personnel state information change from a first state (i.e., the door state information is in a closed state and the personnel state information is that there is a person) to a second state (the door state information is in an open state and the personnel state information is that there is no person) and the duration of the second state. When the duration reaches a preset duration, a target image collected by the image collection unit 106 before the target time point is acquired, so as to identify the target construction worker who last left the construction equipment and did not close the door according to the target image. The above device can determine the time information of the image collected by the image collection unit 106, i.e., the target time point, according to the door state detection unit 102 and the personnel detection unit 104, so as to acquire the target image according to the target time point, and further determine the identity information of the target construction worker according to the target image, thereby realizing accurate positioning of the construction worker who last left the construction equipment and did not close the door, facilitating tracing to the relevant person in charge, thereby attracting the attention of the construction worker to the event of closing the door, avoiding the problem of low working efficiency of the construction equipment due to not closing the door, improving the working efficiency of the construction equipment, and reducing unnecessary time cost waste.

[0043] In one embodiment, the personnel detection unit 104 comprises a weight sensor configured to detect weight information of the construction equipment; the controller 108 is configured to acquire the personnel state information detected by the personnel detection unit 104, including: the controller 108 is configured to: acquire the weight information detected by the weight sensor; and determine whether there is a person in the construction equipment according to the weight information.

[0044] It can be understood that the weight sensor can be used to detect the weight information of the construction equipment, so as to determine whether there is a person in the construction equipment according to the detected weight information. The weight sensor can be installed at the bottom of the construction equipment. For example, the weight sensor can be installed at the bottom of the construction hoist, so as to detect the load of the cage.

[0045] Specifically, the controller 108 can be electrically connected with the weight sensor, so as to acquire the weight information of the construction equipment detected by the weight sensor, and determine whether there is a person in the construction equipment according to the weight information. For example, the weight information is compared with the initial weight value of the construction equipment in the empty state stored in advance. If the deviation between the two reaches a preset weight deviation, it can be determined that there is a person in the construction equipment at this time. Otherwise, it can be determined that there is no person in the construction equipment. The preset weight deviation can be set according to the actual situation, for example, 40kg or 50kg, etc.

[0046] In one embodiment, the personnel detection unit 104 comprises an infrared sensor configured to detect object information in the construction equipment; the controller 108 is configured to acquire the personnel state information detected by the personnel detection unit 104, including: the controller 108 is configured to: acquire the object information detected by the infrared sensor; and determine whether there is a person in the construction equipment according to the object information.

[0047] It can be understood that the infrared sensor can be used to detect the object information in the construction equipment, that is, it can be directly detected whether there is a person in the construction equipment. Specifically, the infrared sensor can be installed inside the construction equipment.

[0048] Specifically, the controller 108 can be electrically connected with the infrared sensor, so as to acquire the object information detected by the infrared sensor, and determine whether there is a person in the construction equipment according to the object information. For example, if there is an object, it can be determined whether the object is a person with vital sign information.

[0049] In one embodiment, the controller 108 is configured to acquire the target image collected by the image collection unit 106 before the target time, including: the controller 108 is configured to: acquire the target image collected by the image collection unit 106 at a time point in a preset time period before the target time.

[0050] It is understandable that the preset time period is a pre-set time period, such as 3 seconds.

[0051] Specifically, the controller 108 can acquire the target image acquired by the image acquisition unit 106 at a time point corresponding to a preset time period (e.g., 3 seconds) before the target time. For example, if the target time is 12:55:57, the time point corresponding to the target image can be 12:55:54, that is, the controller 108 can acquire the target image acquired by the image acquisition unit 106 at the time point of 12:55:54.

[0052] This invention also provides a method for identifying construction workers, such as... Figure 2 As shown, this method is applied to construction equipment including a door. The construction equipment includes a door status detection unit, a personnel detection unit, and an image acquisition unit. The door status detection unit is used to detect the open or closed state of the door, the personnel detection unit is used to detect whether there are personnel inside the construction equipment, and the image acquisition unit is used to acquire images inside the construction equipment. Taking the application of this method to a controller as an example, the method may include the following steps:

[0053] Step S202: Obtain the door status information detected by the door status detection unit and the personnel status information detected by the personnel detection unit.

[0054] Step S204: Obtain the target time when the door status information and personnel status information change from the first state to the second state and the duration of the second state. The first state is when the door status information is closed and the personnel status information is present. The second state is when the door status information is open and the personnel status information is absent.

[0055] Step S206: If the duration reaches the preset duration, acquire the target image acquired by the image acquisition unit before the target time.

[0056] Step S208: Identify the target construction worker based on the target image, wherein the target construction worker is the last construction worker to leave the construction equipment without closing the door.

[0057] It can be understood that the door state detection unit is a detection device or apparatus for detecting the opening and closing state of the door of the construction equipment, which can include, but is not limited to, a door closing detection switch or a door closing in place detection sensor, etc. The personnel detection unit is a detection device or apparatus for detecting whether there is a person in the construction equipment, which can include, but is not limited to, an infrared sensor or a weight sensor, etc. The image acquisition unit is a device or apparatus for acquiring images in the construction equipment, which can include, but is not limited to, a camera, etc. The controller can be connected to the door state detection unit, the personnel detection unit and the image acquisition unit in a wired or wireless manner. The door state information is the state information of the opening and closing state of the door of the construction equipment. The personnel state information is the state information of whether there is a person in the construction equipment. The first state is that the door state information is in a closed state and the personnel state information is that there is a person, i.e., the door of the construction equipment is in a closed state and at the same time there is a person in the construction equipment. The second state is that the door state information is in an open state and the personnel state information is that there is no person, i.e., the door of the construction equipment is in an open state and there is no person in the construction equipment. The target time is the time when the first state changes to the second state. The duration of the second state is the length of time that the second state lasts after the first state changes to the second state. The preset duration is the preset duration of the second state, which can be 3 minutes or 5 minutes, and can be set according to actual conditions. It can be understood that if the duration of the second state reaches the preset duration, it can be basically confirmed that the construction personnel has indeed left the construction equipment and the construction personnel has not closed the door. The target image is the image information acquired by the image acquisition unit before the target time, which usually includes the target construction personnel. It can be understood that the target image can record the face information and / or the shape information sufficient to identify the identity of the construction personnel of the construction personnel who last left the construction equipment and did not close the door. The target construction personnel is the construction personnel who last left the construction equipment and did not close the door. It can be understood that the number of target construction personnel can be one or more.

[0058] Specifically, the controller can acquire the door state information detected by the door state detection unit and the personnel state information detected by the personnel detection unit, and determine according to the door state information and the personnel state information, when the two change from a first state (i.e. the door state information is in a closed state and the personnel state information is that there is a person) to a second state (the door state information is in an open state and the personnel state information is that there is no person), at this time, the target moment can be determined, i.e. the target moment when the door state information and the personnel state information change from the first state to the second state, after which the controller can continue to acquire the door state information and the personnel state information, so as to acquire the duration of the second state after the first state changes to the second state, and compare the duration with a preset duration, when the duration reaches the preset duration, the controller can acquire a target image before the target moment, which can be a period of time before the target moment, for example, 3 seconds before the target moment, i.e. the target image can be an image collected by the image collection unit 3 seconds before the target moment. After acquiring the target image, the controller can identify the specific identity of the target construction personnel according to the target image, for example, the face in the target image can be compared with the face information of all construction personnel collected and stored in advance, so as to determine the identity information of the target construction personnel. Further, the comparison process can be machine comparison through the face recognition algorithm built in the controller.

[0059] The above method for identifying construction personnel, the controller can acquire the door state information detected by the door state detection unit and the personnel state information detected by the personnel detection unit, and acquire the target moment when the door state information and the personnel state information change from a first state (i.e. the door state information is in a closed state and the personnel state information is that there is a person) to a second state (the door state information is in an open state and the personnel state information is that there is no person) and the duration of the second state, in the case that the duration reaches a preset duration, acquire a target image collected by the image collection unit before the target moment, so as to identify the target construction personnel who last left the construction equipment and did not close the door according to the target image. The above method can determine the time information of the image collected by the image collection unit, i.e. the target moment, according to the door state information and the personnel state information, so as to acquire the target image according to the target moment, and further determine the identity information of the target construction personnel according to the target image, so as to accurately locate the construction personnel who last left the construction equipment and did not close the door, facilitate tracing to the relevant person in charge, and further enable the construction personnel to pay attention to the event of closing the door, avoid the problem of low working efficiency of the construction equipment due to not closing the door, improve the working efficiency of the construction equipment, and reduce unnecessary time cost waste.

[0060] In one embodiment, the personnel detection unit comprises a weight sensor configured to detect weight information of the construction equipment; and the personnel state information detected by the personnel detection unit is obtained by: obtaining the weight information detected by the weight sensor; and determining whether there is personnel in the construction equipment according to the weight information.

[0061] It can be understood that the weight sensor can be used to detect the weight information of the construction equipment, so as to determine whether there is personnel in the construction equipment according to the detected weight information. The weight sensor can be installed at the bottom of the construction equipment. For example, the weight sensor can be installed at the bottom of the construction hoist, so as to detect the load of the cage.

[0062] Specifically, the controller can be electrically connected with the weight sensor, so as to obtain the weight information of the construction equipment detected by the weight sensor, and determine whether there is personnel in the construction equipment according to the weight information. For example, the weight information is compared with the initial weight value of the construction equipment in the empty state stored in advance. If the deviation between the two reaches a preset weight deviation, it can be determined that there is personnel in the construction equipment at this time, otherwise it can be determined that there is no personnel in the construction equipment. The preset weight deviation can be set according to the actual situation, for example, 40kg or 50kg, etc.

[0063] In one embodiment, the personnel detection unit comprises an infrared sensor configured to detect object information in the construction equipment; and the personnel state information detected by the personnel detection unit is obtained by: obtaining the object information detected by the infrared sensor; and determining whether there is personnel in the construction equipment according to the object information.

[0064] It can be understood that the infrared sensor can be used to detect the object information in the construction equipment, that is, it can be directly detected whether there is personnel in the construction equipment. Specifically, the infrared sensor can be installed inside the construction equipment.

[0065] Specifically, the controller can be electrically connected with the infrared sensor, so as to obtain the object information detected by the infrared sensor, and determine whether there is personnel in the construction equipment according to the object information. For example, if there is an object, it can be determined whether the object is a person with vital sign information.

[0066] In one embodiment, the target image collected by the image collection unit before the target time is obtained by: obtaining the target image collected by the image collection unit at a time point in a preset time period before the target time.

[0067] It can be understood that the preset time period is a time period set in advance, for example, 3s.

[0068] Specifically, the controller can acquire a target image collected by the image acquisition unit at a time point before a preset time period (for example, 3s) before the target moment. For example, if the target moment is 12:55:57, the time point corresponding to the target image can be 12:55:54, that is, the controller can acquire a target image collected by the image acquisition unit at the time point of 12:55:54.

[0069] In one specific embodiment, taking the construction hoist as an example, a device and method for identifying construction personnel are provided, which can realize rapid searching of personnel who do not close the door in the construction hoist. The device for identifying construction personnel can include a controller, a door closing detection sensor (i.e., a door state detection unit), a camera (i.e., an image acquisition unit), a weight sensor (i.e., a personnel detection unit), and a memory, and their connection relationship can be as shown in Figure 3 The door closing detection switch (i.e., the door closing detection sensor), the weight sensor, the camera, and the controller can be connected by wires, and the memory and the camera can be connected by wires. The door closing detection sensor can be installed on the cage door of the construction hoist, and its function is to detect the closing state of the cage door. The weight sensor can be installed at the bottom of the construction hoist, and its function is to detect the cage load. The camera can be installed at the top of the cage, and its function is to monitor the video in the cage. The memory is an internal device of the camera, and its function is to store the monitoring video.

[0070] The method for identifying construction personnel can include: starting timing when the door closing detection switch detects opening of the door and the weight sensor continuously decreases to the initial value, if no closing of the door is detected within a specified time period, recording the opening time, or storing the video of the period, and then positioning the personnel who do not close the door at the time by calling the video of the period or directly viewing the saved video. The specific implementation process can be as shown in Figure 4 .

[0071] In another specific embodiment, still taking the construction hoist as an example, another device and method for identifying construction personnel are provided, which can replace the weight sensor in the technical solution provided in the above embodiment by adding an infrared sensor to realize detection of the departure of personnel in the cage. The structural diagram of the device for identifying construction personnel can be as shown in Figure 5 , and the flowchart of the method for identifying construction personnel can be as shown in Figure 6 .
