Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices for monitoring personnel climbing a tower, in particular to a plane monitoring device and a three-dimensional monitoring device for monitoring personnel climbing a tower. Background Art

[0002] There are often non-professionals such as non-installation and maintenance personnel near steel structure towers or high-rise structures. Climbing the tower by non-professionals will cause danger. Therefore, it is necessary to install monitoring devices on steel structure towers or high-rise structures to achieve effective perception of tower climbers, so as to monitor whether there are non-professionals climbing the tower, improve the information management level of the tower operation and maintenance management unit, enable it to grasp the situation of non-professionals climbing the tower in real time, reduce personnel risks and damage or loss of assets and property, etc.

[0003] Traditional monitoring sensor types include:

[0004] 1. Infrared sensor: This sensor detects human presence by detecting infrared light emitted by the human body. In the summer, when ambient temperature is close to human body temperature, there is no change in infrared energy when a person enters the sensing range, making human presence sensing very insensitive. Therefore, this sensor is not suitable for long-term outdoor monitoring.

[0005] 2. Ultrasonic sensors: These utilize ultrasonic waves to detect human presence by emitting and detecting reflected ultrasound waves. However, due to their relatively slow ranging speed and limited diffusion angle, ultrasonic sensors can be inaccurate when measuring distance and direction. They are also susceptible to environmental influences such as dust, dirt, and high humidity, which can reduce monitoring reliability.

[0006] 3. Microwave induction sensor: This sensor detects human position and movement by transmitting wireless microwave signals and receiving reflected microwave signals. However, it is susceptible to interference from other electromagnetic signals, which may lead to false alarms. This makes it difficult to meet the monitoring needs of complex outdoor electromagnetic environments.

[0007] 4. Laser Sensors: These detect human presence by emitting and receiving laser light, calculating distance based on the time or phase difference between the reflected and transmitted beams. These sensors utilize high-end lasers, detectors, and signal processing circuits, leading to relatively high costs. They are sensitive to environmental factors such as temperature and humidity, and are susceptible to interference from light pollution, making them unsuitable for monitoring in complex outdoor environments.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0033] First, as Figure 1 As shown, two radars are included, such as radar 1 and radar 2; the two radars respectively use millimeter wave radars, and the extended area of ​​the surface of one of the two radars, such as radar 1, intersects with the extended area of ​​the surface of the other radar, such as radar 2, and the detection range of one of the two radars, such as radar 1, intersects with the detection range of the other radar, such as radar 2, to form an edge overlapping area.

[0034] Specifically, in one optional embodiment, the two radars each utilize a 24 GHz frequency. Each radar has a maximum monitoring angle of 120°. Specifically, in one optional embodiment, the surface of one of the two radars forms a perpendicular configuration to the surface of the other radar. Specifically, in one optional embodiment, the surface of one of the two radars is installed at a downward 45° angle relative to the horizontal plane, while the other radar is installed at an upward 45° angle relative to the horizontal plane.

[0035] Millimeter-wave radar's basic operating principle for sensing the human body is to transmit high-frequency electromagnetic waves in the millimeter wave band and receive signals reflected from the human body. When these waves encounter the human body, they are partially absorbed and reflected due to the unique electromagnetic properties of human tissue and clothing, allowing the detection and tracking of a person's presence and movement.

[0036] The above-mentioned two-dimensional monitoring device for monitoring personnel climbing a tower is based on millimeter-wave radar monitoring technology. The tower can be a steel structure or a tall structure. The two-dimensional monitoring device is used to detect targets climbing the tower. It is equipped with two radars, Radar 1 and Radar 2, operating at a 24GHz frequency. Each radar has a maximum monitoring angle of 120° and a maximum monitoring range of 6 meters. By vertically mounting the two radars, all-round monitoring of targets on the vertical tower is achieved.

[0037] like Figure 2 As shown in FIG, the process of monitoring personnel climbing a tower by a plane monitoring device to realize personnel monitoring is as follows:

[0038] 1) Initial monitoring and target identification: When a target climbs upward from below, Radar-1 near the ground first receives the electromagnetic waves reflected from the target. Radar-1 calculates the distance to the target based on the time interval between the emission and reception of the electromagnetic waves. Based on the intensity and frequency changes of the received reflected electromagnetic waves, the number of people on the target and the angle information can be inferred.

[0039] 2) Continuous monitoring mode: Once Radar-1 identifies a target, it observes whether the target approaches the monitoring point and Radar-1 continuously monitors the target;

[0040] 3) Overlapping area monitoring: If the target continues to climb upward and enters the overlapping monitoring area of ​​the two radars, the two radars will monitor the target together;

[0041] 4) Radar 2 monitoring: When the target exceeds the overlapping area, only Radar 2 near the top can detect the target, and the device continues to monitor the target through Radar 2.

[0042] The above-mentioned plane monitoring device for monitoring people climbing the tower can realize effective perception of people climbing the tower, so as to monitor whether there are non-professionals climbing the tower. It can effectively avoid misidentifying horizontally moving targets such as people walking on the ground or flying birds as climbing targets, helping decision makers to understand the climbing information of the targets in a timely manner and provide decision makers with accurate judgment basis.

[0043] When there is a target near Radar 1, when Radar 1 detects the target, if Radar 1 and Radar 2 do not detect the target at the same time, it is marked as a misjudgment (such as a person walking on the ground); if Radar 1 and Radar 2 detect the target at the same time, and Radar 2 detects the target, it is marked as a person climbing up, and the count is increased by 1.

[0044] When there is a target near Radar 2, when Radar 2 detects the target, if the subsequent Radar 1 and Radar 2 do not detect the target at the same time, it is marked as a misjudgment (such as a flying bird); if the subsequent Radar 1 and Radar 2 detect the target at the same time, and the subsequent Radar 1 detects the target, it is marked as a person climbing down, and the count is increased by 1.

[0045] like Figure 3 As shown, when the above-mentioned plane monitoring device is in use, radar 1 and radar 2 are respectively installed on the slopes on both sides of the supporting platform, and radar 1, radar 2 and the supporting platform are installed in the sensor housing 8. The sensor housing 8 can be placed at the bottom, middle or top of the tower.

[0046] Second, as Figure 4-Figure 7As shown, a three-dimensional monitoring device includes radar 1, radar 2, radar 3, radar 4, radar 5, radar 6, an upper pyramid shell 72, and a lower pyramid shell 71. The radar 1, radar 2, radar 3, radar 4, radar 5, and radar 6 respectively use millimeter wave radars. The upper pyramid shell 72 and the lower pyramid shell 71 are both triangular pyramid-shaped. The bottom surface of the upper pyramid shell 72 is spliced ​​with the bottom surface of the lower pyramid shell 71. Radar 1, radar 2, and radar 3 are respectively installed on the three side surfaces of the lower pyramid shell 71. Radar 4, radar 5, and radar 6 are respectively installed on the three side surfaces of the upper pyramid shell 72. The extended area of ​​the surface of radar 1 intersects with the extended area of ​​the surface of radar 4. The detection range of radar 1 intersects with the detection range of radar 4 to form a first edge overlapping area.

[0047] Specifically, in an optional embodiment, the extended area of ​​the surface of the second radar 2 intersects with the extended area of ​​the surface of the fifth radar 5, and the detection range of the second radar 2 intersects with the detection range of the fifth radar 5 to form a second edge overlap area. The extended area of ​​the surface of the third radar 3 intersects with the extended area of ​​the surface of the sixth radar 6, and the detection range of the third radar 3 intersects with the detection range of the sixth radar 6 to form a third edge overlap area.

[0048] Specifically, in an optional embodiment, the radar 1, radar 2, radar 3, radar 4, radar 5, and radar 6 each use a 24 GHz frequency radar. Specifically, in an optional embodiment, the radar 1, radar 2, radar 3, radar 4, radar 5, and radar 6 each have a maximum monitoring angle of 120° and a maximum monitoring distance of 6 meters.

[0049] Specifically, in an optional embodiment, the surface of the radar 1 forms a vertical structure with the surface of the radar 4 4; the surface of the radar 2 2 forms a vertical structure with the surface of the radar 5 5; and the surface of the radar 3 3 forms a vertical structure with the surface of the radar 6 6.

[0050] like Figure 8 As shown, when the above-mentioned three-dimensional monitoring device is in use, the lower pyramid shell of the three-dimensional monitoring device can be installed on the support column by welding or fixing with connecting parts, and the support column is supported by the bottom platform. The outside of the three-dimensional monitoring device can also be covered with a sensor housing 8.

[0051] This 3D monitoring device offers enhanced versatility and can be applied to a wide range of building structures. Its unique structure, consisting of two triangular pyramids joined together, enhances its adaptability and flexibility while also expanding its monitoring range. This innovative design enables full 360° monitoring without requiring precise adjustment of the mounting angle, ensuring the integrity and accuracy of the monitoring range.

[0052] Every two radars in the device form a group, namely radar 1 and radar 4, radar 2 and radar 5, radar 3 and radar 6. The monitoring process of each group of radars is as follows:

[0053] 1) Initial monitoring and target identification: When a target climbs from below, the electromagnetic beam emitted by the lower radar in each group (radars one, two, and three) is reflected back after encountering the target and is received by the radar;

[0054] 2) Continuous monitoring and overlapping area monitoring: Once a target is identified, the system tracks whether the target approaches the monitoring point. If the target continues to climb upward and enters the upper and lower overlapping areas of the lower and upper radars (including the first edge overlapping area, the second edge overlapping area, and the third edge overlapping area), the lower and upper radars will jointly monitor the target.

[0055] 3) High-level monitoring and misidentification: When a target exceeds the overlapping area of ​​upper and lower monitoring, the upper radar of each group (radars four, five, and six) takes over monitoring to prevent the target from being misidentified.

[0056] The above-mentioned three-dimensional monitoring device can achieve effective perception of tower climbers, so as to monitor whether non-professionals are climbing the tower. It can effectively avoid misidentifying horizontally moving targets such as people walking on the ground or flying birds as climbing targets, and provide decision makers with accurate judgment basis.

[0057] The two-dimensional and three-dimensional monitoring devices utilize millimeter-wave radar technology, which offers excellent anti-interference capabilities and is not susceptible to weather, lighting, or electromagnetic signals. Radar signals can penetrate a variety of media, such as walls and clothing, enabling the devices to monitor people in complex environments, reducing the impact of environmental factors on monitoring results and improving the reliability of monitoring data.

[0058] The above-mentioned stereoscopic monitoring device utilizes an innovative triangular pyramid platform design to achieve full-angle coverage. Compared to conventional multi-device installation strategies requiring multiple devices at various angles, this device only requires one to achieve full coverage, effectively reducing deployment complexity and costs. The unique triangular pyramid shape of the stereoscopic monitoring device eliminates the need for precise angle adjustment, improving its applicability and flexibility, making it adaptable to a variety of complex application scenarios.

[0059] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0060] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
