Description

Technical Field

[0001] This utility model relates to the field of intelligent sensing and data acquisition technology, specifically to an intelligent counting and timing device. Background Technology

[0002] In many fields such as industrial production, warehousing and logistics, sports training, and security monitoring, it is often necessary to automatically count the number of objects, personnel activities, and the number of events, and record the time information simultaneously.

[0003] Traditional counting and timing devices are limited in function, typically relying on a single sensor (such as an infrared photocell or mechanical button) for counting. This results in problems such as susceptibility to interference, inconvenient installation, limited applicability, and limited data dimensions. For example, optical sensors are prone to failure in complex lighting conditions, and sound counting is inaccurate in noisy environments. Furthermore, existing devices often use bolts for fixing, making installation and adjustment extremely inconvenient and difficult to adapt to different mounting surfaces. Therefore, there is an urgent need for an intelligent counting and timing device that integrates multiple sensors, offers flexible installation, and has strong environmental adaptability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent counting and timing device that solves the problems of relying on a single sensor (such as an infrared pair or a mechanical button) for counting, which is susceptible to interference, inconvenient to install, limited applicable scenarios, and single data dimension.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent counting and timing device, comprising a mounting frame, an inertial measurement unit disposed inside the mounting frame, a sealing cover disposed on the front of the mounting frame, a microphone disposed on one side of the surface of the sealing cover, a camera disposed on the other side of the surface of the sealing cover, a lidar disposed on one side of the top of the mounting frame, a positioning plate disposed on the back of the mounting frame, and mounting components disposed at the four corners of the surface of the positioning plate;

[0006] The mounting assembly includes rotating grooves at the four corners of the positioning plate surface. A connecting rod is rotatably connected inside the rotating groove. One end of the connecting rod is provided with a universal ball, and the other end of the connecting rod is rotatably connected to an adjusting cylinder. A threaded rod is threadedly connected inside the adjusting cylinder, and a suction cup is fixedly installed at the bottom of the threaded rod.

[0007] In one specific embodiment, the diameter of the omnidirectional ball is larger than the diameter of the rotating groove, and the omnidirectional ball rotates at the edge of the rotating groove surface.

[0008] In one specific embodiment, a connecting groove is provided at one end of the adjusting cylinder, the size of which is adapted to the diameter of the other end of the connecting rod, and the adjusting cylinder can be rotated through the connecting rod.

[0009] In one specific embodiment, the internal dimensions of the adjusting cylinder are matched with the dimensions of the threaded rod.

[0010] In one specific embodiment, a display screen is provided in the middle of the surface of the sealing cover, and the surface of the display screen is provided with a waterproof membrane to improve waterproof performance.

[0011] In one specific embodiment, connecting blocks are provided at the four corners of the back of the mounting frame, and the back of the connecting blocks is fixedly installed on the front of the positioning plate.

[0012] Compared with the prior art, the present invention provides an intelligent counting and timing device, which has the following beneficial effects:

[0013] The technical solution disclosed in this utility model utilizes multiple sensors such as an inertial measurement unit (IMU), microphone, camera, and lidar to achieve counting and timing functions through various methods including visual recognition, sound feature analysis, laser ranging, and motion sensing. The unique mounting assembly combining a omnidirectional ball joint and an adjusting cylinder allows for angle adjustment in three dimensions. The threaded connection structure between the adjusting cylinder and the threaded rod enables fine-tuning of the device's height.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, an intelligent counting and timing device includes a mounting frame 1, an inertial measurement unit 2 is disposed inside the mounting frame 1, a sealing cover 3 is disposed on the front of the mounting frame 1, a microphone 4 is disposed on one side of the surface of the sealing cover 3, a camera 5 is disposed on the other side of the surface of the sealing cover 3, a lidar 6 is disposed on one side of the top of the mounting frame 1, a positioning plate 7 is disposed on the back of the mounting frame 1, and mounting components 8 are disposed at the four corners of the surface of the positioning plate 7.

[0023] The specific problem addressed in this embodiment is the reliance on a single sensor, such as an infrared photocell or a mechanical button, for counting, which suffers from susceptibility to interference, inconvenient installation, limited applicability, and a single data dimension. This invention utilizes multiple sensors, including an inertial measurement unit (IMU), microphone (4), camera (5), and lidar (6), to achieve counting and timing functions through visual recognition, sound feature analysis, laser ranging, and motion sensing. The unique mounting assembly combining a omnidirectional ball joint (82) and an adjusting cylinder (83) allows for angle adjustment in three dimensions. The threaded connection between the adjusting cylinder (83) and the threaded rod (84) enables fine-tuning of the device's height.

[0024] The mounting assembly 8 includes rotating grooves at the four corners of the positioning plate 7. A connecting rod 81 is rotatably connected inside each rotating groove. One end of the connecting rod 81 has a universal ball 82, and the other end is rotatably connected to an adjusting cylinder 83. A threaded rod 84 is threadedly connected inside the adjusting cylinder 83, and a suction cup 85 is fixedly mounted at the bottom of the threaded rod 84. The diameter of the universal ball 82 is larger than the diameter of the rotating groove, and the universal ball 82 rotates at the edge of the rotating groove surface. One end of the adjusting cylinder 83 has a connecting groove, the size of which matches the diameter of the other end of the connecting rod 81. The adjusting cylinder 83 can rotate via the connecting rod 81. The internal size and length of the adjusting cylinder 83 match the size and length of the threaded rod 84. In this specific embodiment, during use, the universal ball 82 can rotate at multiple angles within the rotating groove, thereby causing the connecting rod 81 to change angles. The adjusting cylinder 83 is rotatably connected to the other end of the connecting rod 81 via the connecting groove at its end and can rotate around this connection point. By rotating the adjusting cylinder 83, the threaded rod 84, which is threaded to it, can be raised or lowered, achieving fine height adjustment. The suction cup 85 at the bottom of the threaded rod 84 is used to adhere and fix it to the target surface.

[0025] In this specific embodiment, a display screen is provided in the center of the surface of the sealing cover 3. The surface of the display screen is covered with a waterproof membrane to improve waterproof performance. Connecting blocks are provided at the four corners of the back of the mounting frame 1. The back of the connecting blocks is fixedly installed on the front of the positioning plate 7. The front of the mounting frame 1 is sealed to the sealing cover 3 through a sealing ring to form a protective level and prevent dust and moisture from entering. A microphone 4 is provided on one side of the surface of the sealing cover 3 for collecting ambient sound; a camera 5 is provided on the other side for collecting visual images; and a display screen is provided in the center for information display. A lidar 6 is provided on the top side of the mounting frame 1 for emitting laser beams and receiving echoes to measure distance and scan contours.

[0026] First, the user adjusts the approximate orientation of the device by manipulating the connecting rod 81 and adjusting cylinder 83 according to the angle of the mounting surface. Then, the user rotates the adjusting cylinder 83 to fine-tune the height and level of the device, ensuring it is at the optimal viewing angle. Finally, the user presses the suction cup 85 firmly onto the mounting surface to complete the fixation. After the device is powered on, the user can select and activate one or more sensors (such as IMU 2, microphone 4, camera 5, and lidar 6) via the main control module as needed. The data collected by the sensors is transmitted to the main control module for analysis and processing, enabling counting and timing functions. The results can be displayed in real time on the screen or transmitted to the cloud or a host computer system via the built-in wireless communication module (such as Wi-Fi / 4G).

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
