[0054] The wall detection mechanism, method, and wall detector of the present invention will now be described in detail with reference to the accompanying drawings.

[0055] like Figures 1 to 3As shown, the wall detection mechanism provided in this embodiment of the invention includes a detection body 10, a rolling ball 20, a first photoelectric component 30, and a second photoelectric component 40. The detection body 10 has a detection center. The rolling ball 20 is rotatably disposed at the detection center around a first direction and a second direction, and the first direction and the second direction are perpendicular to each other on the same plane. The first photoelectric component 30 is disposed on the detection body 10 and abuts against the rolling ball 20, and is used to rotate around the first direction to detect a first movement trajectory. The second photoelectric component 40 is disposed on the detection body 10 and abuts against the rolling ball 20, and is used to rotate around the second direction to detect a second movement trajectory.

[0056] The detection center refers to the extended position of the centerline in the width direction of the detection body 10. A rolling ball 20 and a marker 50 can be set at the detection center of the detection body 10. After detecting metals, wires, and water pipes, the marker 50 can be used to mark the corresponding route trajectory, thereby ensuring that the layout route of metals, wires, and water pipes can be accurately known in subsequent work. It can be understood that the first moving trajectory can be a route trajectory along the second direction, and the second moving trajectory can be a route trajectory along the first direction. Therefore, when the first photoelectric component 30 rotates around the first direction, the first photoelectric component 30 can detect the moving trajectory corresponding to the second direction; when the second photoelectric component 40 rotates around the second direction, the second photoelectric component 40 can detect the moving trajectory corresponding to the first direction.

[0057] The wall detection mechanism provided by this invention can detect metal, wires, and water pipes inside a wall by moving the detection body 10. When the ball 20 moves with the detection body 10, it can rotate around a first direction and a second direction, thereby driving the first photoelectric component 30 and the second photoelectric component 40 to rotate. This allows the detection of the first and second movement trajectories, and the specific layout of the metal, wires, and water pipes inside the wall can be detected through the first and second movement trajectories, resulting in better detection effect.

[0058] Specifically, the first optoelectronic component 30 includes a first grating wheel 31, a first transmitter 32, and a first receiver 33. One end of the grating wheel is in contact with a ball 20. The first transmitter 32 is located at the other end of the first grating wheel 31. The first receiver 33 is located at the other end of the first grating wheel 31 and is opposite to the first transmitter 32, so as to periodically receive the infrared signal from the first transmitter 32 when the first grating wheel 31 rotates. Further, the first grating wheel 31 includes a first abutment portion 311, a first connecting portion 312, and a first scale 313. The abutment portion is adapted to abut against the ball 20. One end of the first connecting portion 312 is connected to the first abutment portion 311. The first scale 313 is connected to the other end of the first connecting portion 312, and the first transmitter 32 and the first receiver 33 are respectively located on both sides of the first scale 313.

[0059] Understandably, the second optoelectronic component 40 includes a second grating wheel 41, a second transmitter 42, and a second receiver 43. One end of the second grating wheel 41 is in contact with a ball 20. The second transmitter 42 is located at the other end of the second grating wheel 41. The second receiver 43 is located at the other end of the second grating wheel 41 and is opposite to the second transmitter 42, so as to periodically receive the infrared signal from the second transmitter 42 when the second grating wheel 41 rotates. Further, the second grating wheel 41 includes a second abutment portion 411, a second connecting portion 412, and a second scale 413. The abutment portion is adapted to abut against the ball 20. One end of the second connecting portion 412 is connected to the second abutment portion 411. The second scale 413 is connected to the other end of the second connecting portion 412, and the second transmitter 42 and the second receiver 43 are respectively located on both sides of the second scale 413.

[0060] In this embodiment, the first transmitter 32 and the second transmitter 42 can be infrared emitting tubes, the first receiver 33 and the second receiver 43 can be infrared receiving tubes, and the first dial 313 and the second dial 413 represent photoelectric dials with encoders; for example, the first receiver 33 and the second receiver 43 can be... Figure 3 The phototransistors A and B are packaged in an up-down orientation. When the roller rotates around the first or second direction, it can drive the first grating wheel 31 or the second grating wheel 41 to rotate together. The first dial 313 periodically blocks the infrared signal emitted by the first transmitter 32 or the second dial 413 periodically blocks the infrared signal emitted by the second transmitter 42, so that the first receiver 33 or the second receiver 43 can periodically receive the corresponding infrared signal. When the first receiver 33 or the second receiver 43 receives the corresponding infrared signal, since the AB phototransistors in the first receiver 33 or the second receiver 43 are arranged vertically, the electrical pulses output by the AB phototransistors have a phase difference. The control chip can accurately determine the phase difference of the electrical pulse to determine the rotation direction of the first grating wheel 31 or the second grating wheel 41. Furthermore, the frequency of the electrical pulse can determine the rotation speed of the first grating wheel 31 or the second grating wheel 41. Thus, the detection body 10 uploads the data to the host computer to obtain the corresponding first and second movement trajectories.

[0061] Reference Figure 4 As shown, the wall detection method proposed in the embodiments of the present invention includes the above-mentioned wall detection mechanism, and the method includes:

[0062] S10. Place the detector 10 in the area to be detected and move it along the first direction and the second direction to obtain the movement trajectory of the detector 10 in the area to be detected.

[0063] Specifically, the above-mentioned method of placing the detection body 10 in the area to be detected and moving it along the first and second directions to obtain the movement trajectory of the detection body 10 in the area to be detected includes: placing the detection body 10 in the area to be detected and pushing it to make the rolling ball 20 drive the first photoelectric component 30 or the second photoelectric component 40 to rotate; performing detection based on the first photoelectric component 30 to determine the first movement trajectory, and performing detection based on the second photoelectric component 40 to determine the second movement trajectory, and storing the first movement trajectory and the second movement trajectory in the host computer.

[0064] In this embodiment, the area to be detected can be a wall or similar area, such as an area that requires drilling during construction. The target object can be metal, wires, water pipes, etc. When detecting the wall, the movement trajectory of the detection body 10 on the wall can be determined. The movement trajectory can include the movement trajectory corresponding to the target object and the movement trajectory corresponding to non-target objects. Therefore, the wall detection mechanism described above can determine the movement trajectory of the detection body 10 in the vertical and horizontal directions during the detection process on the wall. For example, the first movement trajectory can be the vertical movement trajectory and the second movement trajectory can be the horizontal movement trajectory. Thus, the movement trajectories of the detection body 10 for the target object and non-target objects can be stored in the host computer.

[0065] S20. When the target center point corresponding to the target object in the detection area is detected, the detection area is performed based on the target center point to determine multiple trajectory points corresponding to the target object; the target center point and trajectory points are the resonance center point of the target object.

[0066] Specifically, when the target center point corresponding to the target object in the detection area is detected, the detection of the detection area based on the target center point and the determination of multiple trajectory points corresponding to the target object include: when the target center point corresponding to the target object in the detection area is detected, the target object is detected using the target center point as a marker point; and multiple trajectory points of the target object along the first direction and the second direction are determined based on the target center point.

[0067] The system can collect position information of PVC water pipes, metal, and wires through various sensors, convert the measured non-electrical quantity into changes in electrical quantity, amplify it into a voltage signal through various signal conditioning circuits, and then convert the amplified analog voltage signal into a position digital signal through an A / D converter. The signal is then transmitted to the main control chip, which processes the position digital signal and displays the type and position information of the target object on an LCD screen. This determines the resonant center point of the target object, and calibration can be performed based on the resonant center point of the target object.

[0068] S30. Based on the movement trajectory and multiple trajectory points, the trajectory of the target object in the area to be detected is obtained.

[0069] Specifically, the above-mentioned method of connecting the movement trajectory and multiple trajectory points to obtain the path trajectory of the target object in the detection area includes: determining multiple target trajectory points that coincide with the movement trajectory among multiple trajectory points based on the movement trajectory; fitting and connecting the movement trajectories corresponding to the target trajectory points to obtain the path trajectory of the target object in the detection area and outputting it to the visualization interface.

[0070] In this embodiment, the host computer stores the movement trajectories of the target object and non-target objects. Therefore, by determining that multiple target trajectory points of the target object are located on the target object's movement trajectory, a fitting connection can be made based on the target trajectory points and the corresponding movement trajectory. The connection is then output and displayed on the visualization interface of the detection body 10 through the host computer. The trajectory of the target object on the wall can be calibrated based on the displayed movement trajectory to determine the internal direction of the target object. Optionally, a marker 50 can be set on the detection body 10 to mark the direction of the target object. For example, a graphite marker 50 can be set at the detection center of the detection body 10. When marking is needed, the graphite marker 50 can be pressed down to mark. This allows for accurate determination of the target object's route trajectory during wall construction, avoiding damage.

[0071] The wall detector provided in the embodiments of the present invention includes the wall detection mechanism as described above. This wall detector can detect metal, electrical wires, and water pipes within a wall. The rolling ball 20 rotates around a first direction and a second direction as it moves with the detection body 10, thereby driving the first photoelectric component 30 and the second photoelectric component 40 to rotate. This allows the detection of a first moving trajectory and a second moving trajectory, thus determining the specific layout of the metal, electrical wires, and water pipes inside the wall, resulting in better detection performance.
