Description

Technical Field

[0001] This utility model relates to the field of AR glasses applications, and in particular to a high-rise building inspection device. Background Technology

[0002] Traditional railway station inspections require manual recording of large amounts of data. In response, some existing technologies introduce AR technology to help reduce the workload, improve the comprehensiveness of inspections, and reduce the recording tasks for staff.

[0003] For example, Chinese patent CN206365530U discloses an AR smart inspection helmet. This AR smart inspection helmet includes a helmet shell, with a headlamp, camera, sound pickup, temperature sensor, humidity sensor, hazardous gas sensor, AR image display device, and controller mounted on the outside of the helmet shell. The control motherboard is connected to the camera, sound pickup, temperature sensor, humidity sensor, and hazardous gas sensor. Recording switches, photo switches, video recording switches, and intercom switches are evenly distributed on the AR glasses. The AR image display device is located on the outer side of the brim. The sound pickup allows for convenient communication, and during communication, a miniature recorder records the conversation. The temperature and hazardous gas sensors detect the ambient temperature and atmospheric gases, and adjust the settings according to preset temperatures and gas types.

[0004] However, the existing technologies mentioned above still cannot dynamically record the current location. In response, some people skilled in the art hope to use AR helmets or glasses to record the wearer's location, thereby adding location tags to the photos taken. To this end, some indoor positioning technologies have been introduced into AR smart inspection helmets / glasses. Among them, the most widely used is indoor positioning technology based on RFID and WIFI signals. However, if this technology needs to improve the accuracy of elevation positioning, it requires the deployment of a sufficient number of beacons in the site, which places high demands on the modification of the site. Therefore, some people skilled in the art have considered using barometric pressure-based elevation positioning technology, specifically using a barometric pressure sensor + MI geomagnetic sensor to achieve 3D indoor precise navigation and apply it to AR smart inspection helmets / glasses to achieve elevation positioning.

[0005] However, in existing technologies, barometric pressure sensors and magnetic field sensors are generally integrated on a single PCB board, and there are no requirements for their installation positions. This results in significant errors in the positioning results due to the inconsistent positions of the sensing elements of the barometric pressure sensor and the magnetic field sensor. Utility Model Content

[0006] The purpose of this invention is to provide a high-rise building inspection device.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A high-rise building inspection device includes a main processor, AR glasses and bone conduction headphones, both connected to the main processor. The AR glasses include a glasses shell and a geomagnetic sensor and a barometric pressure sensor disposed within the glasses shell. The geomagnetic sensor includes two magnetic induction rings and a first sensor circuit. The barometric pressure sensor includes a pressure sensing plate and a second sensor circuit. The first sensor circuit and the second sensor circuit are integrated into the same electronic unit. The two magnetic induction rings are perpendicular to each other and their centers coincide. The pressure sensing plate is located within the two magnetic induction rings, and the center of the pressure sensing plate is located at the center of the magnetic induction rings.

[0009] The AR glasses also include a plastic support plate, the pressure sensing pad is fixed to the plastic support plate by a first plastic support column, and the magnetic induction ring is fixed to the plastic support plate by a second plastic support column.

[0010] The projection areas of all the first plastic support columns on the plastic support plate do not overlap with the projection area of ​​the magnetic induction ring on the plastic support plate.

[0011] All first plastic support columns and all second plastic support columns are arranged in parallel.

[0012] The pressure sensing plate is arranged parallel to one of the magnetic induction rings.

[0013] In two magnetic induction rings, the signal line of one magnetic induction ring is coplanar with the signal line of the other magnetic induction ring.

[0014] The signal line of the pressure sensor passes through the gap between the two magnetic induction rings and is then connected to the second sensor circuit within the electronic unit.

[0015] The angle between the signal line of the pressure sensing plate and the plane containing the two magnetic induction rings is the same.

[0016] The AR glasses also include an optical lens, a micro-projection module, a front-facing camera, and a telescope lens, all of which are mounted on the glasses housing.

[0017] The AR glasses also include a touch input panel, which is located on the outer side of the glasses housing.

[0018] The main processor, AR glasses, and bone conduction headphones are all connected wirelessly.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By integrating a geomagnetic sensor and a barometric pressure sensor, especially by placing the center of the pressure sensor at the center of the magnetic induction ring and connecting it to their respective sensor circuits via leads, the accuracy of relative vertical height changes can be improved by setting the centers of the sensing elements of the barometric pressure sensor and the MI geomagnetic sensor at the same location. This can improve the accuracy of vertical positioning in indoor positioning.

[0021] 2. All sensing elements are fixed by using plastic support plates and plastic support columns, which can avoid measurement errors caused by metal cutting the geomagnetic field.

[0022] 3. In the two magnetic induction rings, the signal line of one magnetic induction ring is coplanar with the signal line of the other magnetic induction ring, which can reduce the influence of the magnetic field generated by the current in the signal line on the measurement.

[0023] 4. The angle between the signal line of the pressure sensor and the plane containing the two magnetic induction rings is the same, which can avoid measurement errors in different orthogonal directions.

[0024] 5. The touch input panel is located on the outer side of the glasses shell, which improves the ease of operation and does not affect image acquisition during operation. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "proximal end," "farthest end," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Physical quantities in formulas, unless otherwise specified, should be understood as basic quantities of the International System of Units (SI) base units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation, or integration.

[0032] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] A high-rise building inspection device, such as Figure 1 As shown, the system includes a main processor 200, AR glasses 100 and bone conduction headphones 300, both connected to the main processor 200. The AR glasses 100 includes a glasses housing and a geomagnetic sensor and a barometric pressure sensor housed within the housing. The geomagnetic sensor includes two magnetic induction rings and a first sensor circuit. The barometric pressure sensor includes a pressure sensing element and a second sensor circuit. The first and second sensor circuits are integrated into the same electronic unit, such as... Figure 3As shown, two magnetic induction rings are perpendicular to each other and their centers coincide. The pressure sensor is located inside the two magnetic induction rings, and the center of the pressure sensor is located at the center of the magnetic induction rings.

[0036] By integrating a geomagnetic sensor and a barometric pressure sensor, especially by placing the center of the pressure sensor at the center of the magnetic induction ring and connecting it to their respective sensor circuits via leads, the accuracy of relative vertical height changes can be improved by setting the centers of the sensing elements of the barometric pressure sensor and the MI geomagnetic sensor at the same location. This can improve the accuracy of vertical positioning in indoor positioning.

[0037] Furthermore, in some embodiments, the AR glasses 100 also includes a plastic support plate. The pressure sensing element is fixed to the plastic support plate by a first plastic support column, and the magnetic induction ring is fixed to the plastic support plate by a second plastic support column. Using a plastic support plate and plastic support columns to fix all sensing elements avoids measurement errors caused by metal-to-metal interaction affecting the Earth's magnetic field. Of course, in other embodiments, the plastic support plate can be replaced with other rigid, non-magnetic, and non-conductive materials. Similarly, the first and second plastic support columns can also be replaced with other rigid, non-magnetic, and non-conductive materials. The rigidity is to avoid measurement errors caused by deformation, the non-magnetic nature is to avoid magnetic field interference, and the non-conductive nature is to avoid affecting the induced current.

[0038] Specifically, in all embodiments, the projection areas of all first plastic support columns on the plastic support plate do not overlap with the projection area of ​​the magnetic induction ring on the plastic support plate. Furthermore, in these embodiments, all first plastic support columns and all second plastic support columns are arranged in parallel, thereby facilitating installation and design.

[0039] In some embodiments, the pressure sensing element is arranged parallel to one of the magnetic induction rings, and the signal line of one magnetic induction ring is coplanar with the signal line of the other magnetic induction ring, thereby reducing the influence of the magnetic field generated by the current in the signal line on the measurement.

[0040] Furthermore, the signal line of the pressure sensor passes through the gap between the two magnetic induction rings and connects to the second sensor circuit in the electronic unit. Also, the angle between the signal line of the pressure sensor and the plane containing the two magnetic induction rings is the same, which can avoid measurement errors in different orthogonal directions.

[0041] The improvement in this application lies in the combined design of the sensing elements of the barometric pressure sensor and the geomagnetic sensor. The specific integration of the first sensor circuit and the second sensor circuit into the same electronic unit is a common practice in the field, so it will not be described in detail here. The specific method can be to simply splice the two sensor circuits on a PCB, or to use other methods. After the barometric pressure sensor and the geomagnetic sensor are combined, a barometric pressure-geomagnetic coupling sensor 105 is obtained.

[0042] Furthermore, similar to existing technologies, such as Figure 2 As shown, the AR glasses 100 also includes an optical see-through lens 101, a micro-projection module 102, a front-facing camera 103, and a telephoto lens 104. All components are mounted on the glasses housing. Furthermore, the AR glasses 100 also includes a touch input panel 106, which is located on the outer side of the glasses housing, thereby improving ease of operation without affecting image acquisition.

[0043] In some embodiments, the main processor 200, AR glasses 100, and bone conduction headphones are all connected wirelessly. Of course, in other embodiments, they can also be connected via a connecting cable. In addition, in some embodiments, some existing designs can be used to integrate the bone conduction headphones into the end of the AR glasses 100.

[0044] The application process of this application is similar to most existing technologies. Inspection personnel wear AR glasses 100100 and collect images of the building surface through the forward-facing camera 104. The main processor 200 identifies safety risks such as cracks and displacements through existing software. The identification results are overlaid on the real scene through the micro-projection module 102 using existing software. Data interaction is carried out through the interaction unit with bone conduction headphones as the main body.
