Description

Technical Field

[0001] This utility model relates to the field of sensor experimental platform technology, and in particular to a modular sensor experimental platform. Background Technology

[0002] The sensor test bench is a comprehensive experimental platform that integrates multiple sensors, data acquisition modules and other functional units. Its application scenarios cover a wide range of fields such as education, scientific research, industry, and the Internet of Things. Its core value lies in verifying sensor performance, developing application solutions and cultivating practical skills through simulated or real-world scenarios.

[0003] To facilitate simultaneous learning from multiple sensors, current sensor experimental platforms are typically integrated structures, meaning that multiple sensors are installed on a single platform. Among these sensors, some play a more important role than others. Therefore, research and teaching require focused development and explanation of specific sensors. However, due to the large size of the experimental platform, it is difficult to move the entire platform to a research office or classroom. Even after relocation, only a few specific sensors are used, making the overall use of the platform extremely inconvenient. To address this, a modular sensor experimental platform is proposed to solve the technical problem of inconvenient relocation of current sensor experimental platforms when only a portion of the sensors are used. Utility Model Content

[0004] The main purpose of this invention is to provide a modular sensor experimental platform, which aims to solve the technical problem of inconvenient transfer when only some sensors are used in the current sensor experimental platform.

[0005] To achieve the above objectives, the modular sensor experimental platform proposed in this utility model includes: Frame; The installation module is detachably connected to the frame, and the installation modules form at least one row of module groups. The installation modules in each module group are connected in series, and each row of module groups is connected in parallel. The branch circuit includes a positive branch circuit and a negative branch circuit, wherein the positive branch circuit and the negative branch circuit are respectively connected in parallel with the module group; A module group, comprising multiple sensors, wherein the sensors are mounted on the mounting module; A power supply is provided, which is electrically connected to the mounting module and the branch to power the sensor. One of the mounting modules is detached from the module group, and the positive branch is connected to the negative branch, which is connected to the detached module group and the power supply.

[0006] Optionally, in one embodiment of this utility model, the installation modules are all detachably connected to the frame.

[0007] Optionally, in one embodiment of the present invention, the installation module has a power terminal, and adjacent installation modules are connected in series via a bridging component to form a series connection.

[0008] Optionally, in one embodiment of the present invention, the sensor includes a first sensor, the first sensor comprising: Laser rangefinder; A sliding component is connected to the mounting module, and the sliding direction of the sliding component is the same as the illumination direction of the laser rangefinder. A baffle is connected to the sliding assembly and is located in the illumination path of the laser rangefinder to calculate the distance from the laser rangefinder to the baffle.

[0009] Optionally, in one embodiment of the present invention, the sensor includes a second sensor, the second sensor comprising: Accelerometer and angular velocity sensor; A truncated cone, wherein the acceleration and angular velocity sensor is magnetically connected to the protrusion of the truncated cone to adjust the position and orientation of the acceleration and angular velocity sensor; A sliding component, one end of which is connected to the mounting module, and the other end of which is connected to the frustum via a damped universal ball.

[0014] Optionally, in one embodiment of the present invention, the side of the mounting panel on which the sensor is mounted has a teaching area.

[0015] Compared with existing technologies, this utility model achieves at least the following beneficial effects. The technical solution of this utility model consists of a frame, mounting modules, branch circuits, module groups, and a power supply. By using mounting modules, each sensor is an independent structure. The detachable connection between the mounting modules and the frame allows the sensors to be removed. For ease of operation and assembly, existing experimental platforms typically use a single power supply. When a sensor (mounting module) is removed, the entire circuit is broken, rendering other sensors connected in series unusable. To reduce the impact of removing the mounting module on other sensors, positive and negative branches are provided, each connected in parallel with the module group. With the positive and negative branches, even after a sensor and its mounting module are removed from the module group, the positive and negative branches still allow a circuit to be formed between the removed module group and the power supply. Removing one mounting module does not affect the use of the remaining modules. This solution allows for the removal of the required sensors without affecting the use of other sensors.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] The emergence of integrated sensor experimental platforms allows for the mounting of multiple sensors on a single platform, improving the convenience of scientific research, teaching, and popular science. However, when researchers want to conduct targeted development, testing, or demonstrations of a specific sensor, the shortcomings of current integrated experimental platforms become apparent. Due to their large overall size, these platforms are typically placed in a fixed location, requiring users to travel to that area when needed.

[0024] Therefore, referring to Figures 1-2 This utility model proposes a modular sensor experimental platform, which consists of a frame 100, a mounting module 200, branches, and module groups ( Figure 1 The system consists of three module groups (each row being one module group) and a power supply 700. For ease of explanation, the following description of disassembling a sensor refers to simultaneously removing the sensor and its mounting module 200.

[0025] Specifically, the frame 100 serves as the overall skeleton of the experimental platform, and all functional units are installed on the frame 100, which provides support for the various functional units. Multiple mounting modules 200 are provided for mounting different sensors, and at least one mounting module 200 is detachably connected to the frame 100. While there are many types of sensors, a few are typically of greater importance and require focused development or explanation in research, teaching, or other fields. One or more important sensors are mounted on the detachable mounting module 200. When intensive development testing or teaching is needed, the specific mounting module 200 can be removed and taken to the laboratory or classroom for use.

[0026] Furthermore, for ease of operation and assembly, an experimental platform is usually powered by a single power supply. When a sensor (mounting module 200) is removed, it will cause an open circuit, which will prevent other sensors in the same module group from being used. In order to reduce the impact of removing the mounting module 200 on the other sensors, a positive branch 310 and a negative branch 320 are set up, and the positive branch 310 and the negative branch 320 are connected in parallel with the module group respectively.

[0027] After setting up the positive branch 310 and the negative branch 320, when a sensor and its mounting module 200 are removed from the module group, the removed module group and the power supply 700 can still be connected through the positive branch 310 and the negative branch 320, so removing one sensor does not affect the use of the other sensors.

[0028] Furthermore, in one specific embodiment, all connections between the mounting modules 200 and the frame 100 are configured to be detachable, so that all sensors can be detached for use.

[0029] After setting up the positive branch 310 and the negative branch 320, removing one sensor in a module group or removing several consecutive sensors in different module groups will not affect the remaining sensors.

[0030] In addition, compared with the method of setting up a separate power supply for each sensor, this solution has a simpler structure and is easier to assemble.

[0031] However, when disassembling a module group at intervals, some sensors may become unusable. For example, if sensors in a module group are connected in sequence as ABCDEF, and sensors B and D are removed, an ACEF structure will be formed. Due to the presence of the positive branch 310 and the negative branch 320, sensors A, E, and F will still have a connection circuit with the power supply and can be used normally. However, sensor C will become unusable. In this case, sensor C can be connected in series with sensor A or sensor E through an external circuit to ensure the normal use of sensor C.

[0032] In addition, during the assembly of the experimental platform, the frequency of subsequent disassembly of different sensors can be assessed in advance. Sensors that need to be frequently disassembled can be arranged adjacently or placed in different module groups. This approach can also reduce the possibility of the above situation occurring.

[0033] Reference Figure 1 and Figure 7Furthermore, the installation module 200 is provided with a power terminal 211, which is connected to the power terminals 211 of two adjacent installation modules 200 through a bridging component 600, forming a series connection of installation modules 200 in the same group.

[0034] After using the bridging connector 600 to connect the mounting modules 200 in series, if the aforementioned sensor C becomes unusable, the position of sensor C can be moved closer to sensor A or sensor E, and then the connection can be completed using the bridging connector 600. It is understood that even if the position of sensor C is moved, there is still enough space to reinstall sensors B and D; therefore, moving the position of sensor C will not affect the subsequent reinstallation and use of the sensors.

[0035] In this embodiment, each mounting module 200 has at least three sets of power supply terminals 211, and the aperture of at least one set of power supply terminals 211 is different from that of the other power supply terminals 211, so as to improve the adaptability to different types of power supply lines.

[0036] Each mounting module 200 has two positive terminals and two negative terminals at its corners to facilitate the connection of two adjacent mounting modules 200 using the bridging connector 600. With this structure, the bridging connector 600 is small in size and will not affect the observation or demonstration on the experimental platform.

[0037] Understandably, the mounting module 200 also has wiring terminals with other functions, such as signal wiring terminals. When the mounting module 200 is removed, different lines, such as power lines and signal lines, can be connected to the corresponding wiring terminals to complete the power supply and signal reading of the sensor.

[0038] Reference Figures 3-4 Specifically, the mounting module 200 consists of a mounting panel 210 and a mounting housing 220. One side of the mounting panel 210 is used to mount the sensor, and the other side is connected to the mounting housing 220. For ease of popular science or teaching, the mounting panel 210 has a teaching area 212 for placing or drawing the schematic diagram of the corresponding sensor. The mounting housing 220 has heat dissipation holes and a hollow internal structure for housing other functional components that support the normal operation of the sensor.

[0039] Reference Figures 4-5 The frame 100 is provided with a spacer 110, which is used to separate different module groups. At the same time, a limiting groove 111 is provided on the spacer 110, and a part of the mounting panel 210 extends into the limiting groove 111, which fixes the mounting module 200 to a certain extent.

[0040] It should be noted that the above is the preferred structure for detachable connection between the installation module 200 and the frame 100. Other detachable connection methods, such as threaded connection, can also be used.

[0041] Furthermore, referring to Figure 6 The frame 100 is also equipped with a door 120. Specifically, the door 120 is located on the back of the frame 100 and is used for inspection and disassembly of the installation module 200. When disassembling the installation module 200, first open the door 120, then lift the installation panel 210 away from the limiting groove 111 through the installation housing 220, and then remove the installation module 200.

[0042] Furthermore, the platform in this solution consists of a mounting frame, a tabletop 130, support legs 140, and a function box 150. The mounting frame is detachably connected to the mounting module 200, and the mounting frame is equipped with a door 120 and a partition frame 110. The tabletop 130 has the mounting frame above it and the support legs 140 below it. In addition to the mounting frame, the tabletop 130 also has an operating area. The support legs 140 are connected to the function box 150, and the support legs 140 and the function box 150 simultaneously provide support for the mounting frame and the tabletop 130.

[0043] In this embodiment, multiple sensors can be set, including a first sensor 400 and a second sensor 500, wherein the first sensor 400 is a ranging sensor and the second sensor 500 is an acceleration and angular velocity measuring sensor.

[0044] Specifically, refer to Figure 7 The first sensor 400 includes a laser rangefinder 410, a sliding component 420, and a baffle 430. The sliding component 420 is connected to the baffle 430, and the baffle 430 is located on the illumination path of the laser rangefinder 410. At this time, the distance measured by the laser rangefinder 410 is the distance between the laser rangefinder 410 and the baffle 430. The sliding direction of the sliding component 420 is the same as the illumination direction of the laser rangefinder 410. Thus, the value measured by the laser rangefinder 410 can be changed by sliding the baffle 430, thereby demonstrating the function of the laser rangefinder 410.

[0045] Reference Figure 8The second sensor 500 includes an acceleration and angular velocity sensor 510, a frustum 520, a damped universal ball 530, and a sliding assembly 420. The acceleration and angular velocity sensor 510 is magnetically connected to the frustum 520, and the frustum 520 is connected to the sliding assembly 420 via the damped universal ball 530. In this structure, the position of the frustum 520 can be changed by the damped universal ball 530, thereby changing the pose of the acceleration and angular velocity sensor 510. Since the range of motion of the damped universal ball 530 is limited, the structure of the frustum 520 can further expand the range of pose change of the acceleration and angular velocity sensor 510. The acceleration and angular velocity sensor 510 is moved by the sliding assembly 420, thereby demonstrating the function of the acceleration and angular velocity sensor 510.

[0046] The above are just two specific installation methods for sensors. Different sensors can be installed according to different requirements. Figure 1 , 3 Sensors are not shown in either of the following: 1, 2, or 3.

[0047] The sliding component 420 in the first sensor 400 and the second sensor 500 can have the same structure or different structures, which is not restricted here. In addition, since the sliding structure is common knowledge to those skilled in the art, it will not be described in detail.

[0048] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
