Description

Technical Field

[0001] The utility model relates to an accelerometer, in particular to a wireless intelligent accelerometer. Background Art

[0002] An accelerometer is a device that measures acceleration and is commonly used in applications such as aircraft attitude monitoring and adjustment, and building structure vibration monitoring. Existing accelerometers acquire acceleration data through a built-in uniaxial or triaxial MEMS acceleration sensor. This data is connected to a data collector via an RS485 interface. The data collector then uploads the raw data to an IoT platform via wired or wireless transmission.

[0003] Vibration sensors with this structure lack local computing power and rely on servers for centralized data processing after data upload. While this architecture facilitates centralized data management, it is cumbersome because raw data must be uploaded to the platform for computation. Data upload requires communication bandwidth, which can cause latency. This is especially true in large-scale sensor networks, where the high sampling rate and large volume of vibration data lead to high transmission and storage costs. Furthermore, in remote or complex environments, network interruptions can lead to data loss. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a wireless intelligent accelerometer with an integrated edge computing module to improve data processing capabilities, reduce data transmission and storage costs, and avoid data loss problems in complex environments.

[0005] The wireless intelligent accelerometer of the present invention includes a shell, in which an acceleration sensor, a power management module, a communication module and a data acquisition module are arranged. The shell is also provided with an edge computing module. In the inner cavity of the shell, a top circuit board, an upper circuit board, a lower circuit board and a bottom circuit board are arranged in sequence from top to bottom. The top circuit board, the upper circuit board, the lower circuit board and the bottom circuit board are arranged in parallel and are fixedly connected to the shell. The acceleration sensor is arranged on the bottom circuit board, the data acquisition module and the edge computing module are arranged on the lower circuit board, the communication module is arranged on the upper circuit board, and the power management module is arranged on the top circuit board.

[0006] The advantage of this wireless intelligent accelerometer is that it integrates a data acquisition module and an edge computing module, which enables it to collect and analyze local vibration data. The system can implement related functions such as alarms based on the results of data analysis.

[0007] This type of accelerometer architecture can eliminate system delays caused by data uploading and cloud computing, thereby meeting the system's real-time requirements.

[0008] Since the data is processed locally, the data transmission burden is reduced. Through edge computing, the device only needs to upload key analysis results or alarm information to reduce the amount of data and reduce data communication and storage costs.

[0009] In the event of network interruption or complex environment, due to the setting of the edge computing module, the device can still independently complete basic monitoring tasks. After the network is restored, the system can upload relevant data to the platform server, thereby improving the reliability of the smart accelerometer.

[0010] Since the frequency of wireless communication is reduced, the battery life of the device is also extended, which enables it to support long-term unattended operation, making it suitable for deployment in remote areas and meeting environmental protection requirements.

[0011] Furthermore, in the wireless intelligent accelerometer of the present invention, the shell includes an upper shell and a lower shell, connecting pins are respectively provided at the four corners of the surface of the lower shell, and connecting holes corresponding to the connecting pins are correspondingly provided on the surface of the upper shell.

[0012] The arrangement of the connecting pins and the connecting holes facilitates the operator to connect the upper shell to the lower shell via the connecting pins and the connecting holes, and the structure is simple and the operation is convenient.

[0013] Furthermore, in the wireless intelligent accelerometer of the present invention, the connecting pin is a column with a diameter gradually increasing from top to bottom, and the inner diameter of the connecting hole is smaller than the maximum diameter of the bottom of the column.

[0014] The cylinder with a gradually increasing diameter from top to bottom enables the connecting pin to be tightly connected to the upper shell, thereby preventing the upper shell from being loosened from the lower shell.

[0015] Furthermore, the wireless intelligent accelerometer of the present invention also includes a mounting frame, which includes a base plate, a connecting plate fixed at one end of the base plate, a mounting hole being opened on the connecting plate, the shell being fixed on the base plate, and the bottom circuit board being located on a side close to the base plate.

[0016] The provision of the mounting bracket facilitates the operator to install the wireless intelligent accelerometer on the monitored object, thereby realizing vibration detection of the detected object.

[0017] Furthermore, in the wireless intelligent accelerometer of the present invention, an antenna is provided on the shell, and one end of the antenna passes through a through hole on the shell and is connected to an interface on the upper circuit board.

[0018] The setting of the antenna improves the communication effect of the wireless communication module, so that the wireless intelligent accelerometer can adapt to complex environments.

[0019] Furthermore, in the wireless intelligent accelerometer of the present invention, the shell is made of plastic or aluminum alloy.

[0020] Objects made of plastic or aluminum alloy have a longer service life and are safer.

[0021] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it in accordance with the contents of the specification, the following embodiments of the present invention are described in detail.

[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Example 1: See Figures 1 to 6 The wireless intelligent accelerometer of this embodiment includes a shell 1, in which an acceleration sensor, a power management module, a communication module and a data acquisition module are arranged. The shell is also provided with an edge computing module. In the inner cavity of the shell, a top circuit board 2, an upper circuit board 3, a lower circuit board 4 and a bottom circuit board 5 are arranged in sequence from top to bottom. The top circuit board, the upper circuit board, the lower circuit board and the bottom circuit board are arranged in parallel and are fixedly connected to the shell. The acceleration sensor is arranged on the bottom circuit board, the data acquisition module and the edge computing module are arranged on the lower circuit board, the communication module is arranged on the upper circuit board, and the power management module is arranged on the top circuit board.

[0031] The advantage of this wireless intelligent accelerometer is that it integrates a data acquisition module and an edge computing module, which enables it to collect and analyze local vibration data. The system can implement related functions such as alarms based on the results of data analysis.

[0032] This type of accelerometer architecture can eliminate system delays caused by data uploading and cloud computing, thereby meeting the system's real-time requirements.

[0033] Since the data is processed locally, the data transmission burden is reduced. Through edge computing, the device only needs to upload key analysis results or alarm information to reduce the amount of data and reduce data communication and storage costs.

[0034] In the event of network interruption or complex environment, due to the setting of the edge computing module, the device can still independently complete basic monitoring tasks. After the network is restored, the system can upload relevant data to the platform server, thereby improving the reliability of the smart accelerometer.

[0035] Since the frequency of wireless communication is reduced, the battery life of the device is also extended, which enables it to support long-term unattended operation, making it suitable for deployment in remote areas and meeting environmental protection requirements.

[0036] The structural design of the parallel arrangement of the top circuit board, upper circuit board, lower circuit board, and bottom circuit board not only ensures the overall structural stability of the device, but also reduces the overall area of ​​the device, thereby facilitating the storage, transportation, and installation of the device.

[0037] The accelerometer, used to collect acceleration and vibration data, can be a high-precision MEMS accelerometer. It can be fixed to the underlying circuit board via a high-rigidity base, ensuring close proximity to the surface of the object being measured at the bottom of the housing, thereby reducing errors introduced by environmental noise and installation. It can be configured with a multi-protocol wireless transmission module, supporting communication methods such as Wi-Fi, LoRa, and NB-IoT, to meet the needs of various scenarios.

[0038] The data acquisition module and the edge computing module are arranged on the lower circuit board. The data acquisition module includes an analog-to-digital converter ADC, which converts the analog signal output by the acceleration sensor into a digital signal and transmits the digital signal to the edge computing module, which processes the signal accordingly.

[0039] The edge computing module includes embedded signal processing units, such as FPGAs and DSPs. It runs a variety of intelligent analysis algorithms, including vibration frequency extraction, time series analysis, and real-time anomaly detection. The edge computing module independently analyzes vibration characteristics and generates compact result data, reducing the system's reliance on subsequent transmission.

[0040] The communication module is arranged on the upper circuit board and is connected to the edge computing module for transmitting a small amount of critical data to the platform server. It is preferably a wireless communication module to facilitate the installation and deployment of the device.

[0041] The power management module is used to provide power to the system. It can convert the input voltage to the voltage value required by the system to meet the power supply requirements of the system.

[0042] The above-mentioned power management module, communication module, data acquisition module, acceleration sensor, and edge computing are all existing products or devices that can be purchased on the market. Their specific structures and principles are existing technologies and will not be repeated here.

[0043] In specific implementations, connecting posts can be provided between adjacent circuit boards to enhance the overall stability of the four-layer circuit board. The edges of each circuit board can be snapped into positioning slots on the inner wall of the housing to achieve connection with the housing, or they can be directly fixed to the inner wall of the housing with screws. Devices or circuits on adjacent circuit boards can be directly connected via wires, or connecting electrodes can be provided within the connecting posts, with one end of the connecting electrode connected to the wire on the surface of the upper circuit board and the other end of the connecting electrode connected to the wire on the surface of the lower circuit board, thereby achieving connection and communication between adjacent circuit boards.

[0044] The housing comprises an upper housing 6 and a lower housing 7. Connecting pins 8 are provided at the four corners of the lower housing surface. The upper housing surface is provided with corresponding connecting holes corresponding to the connecting pins. The connecting pins can be cylindrical in shape, with diameters gradually increasing from top to bottom. The inner diameter of the connecting holes is slightly smaller than the maximum diameter of the bottom of the cylinder. During connection, the operator aligns the connecting holes on the upper housing surface with the connecting pins on the lower housing surface and then presses the connecting pins into the connecting holes, thereby connecting the upper and lower housings. Since the bottom diameter of the connecting pins is slightly larger than the inner diameter of the connecting holes, this ensures that the connecting pins can be tightly installed in the connecting holes, preventing the upper and lower housings from loosening.

[0045] To enhance communication, the housing may be provided with an antenna 9. One end of the antenna passes through a hole in the housing and connects to a port on the upper circuit board. This antenna is then connected to the communication module via a wire on the upper circuit board. This antenna enhances the communication performance of the wireless communication module.

[0046] To facilitate installation, the wireless intelligent accelerometer also includes a mounting bracket, which consists of a base plate 10. A connecting plate 11 with mounting holes 12 is fixed to one end of the base plate. The housing is fixed to the base plate, with the underlying circuit board located near the base plate. During installation, the operator secures the connecting plate to the desired position with screws and aligns the base plate with the surface of the object being measured, allowing the accelerometer to sense the object's vibrations.

[0047] A bracket or base for installing solar panels can be reserved on the bottom plate to facilitate the subsequent installation of solar mounting panels, thereby further improving its endurance performance.

[0048] Preferably, the shell includes an upper shell and a lower shell, connecting pins are respectively provided at the four corners of the surface of the lower shell, and connecting holes corresponding to the connecting pins are correspondingly provided on the surface of the upper shell.

[0049] The arrangement of the connecting pins and the connecting holes facilitates the operator to connect the upper shell to the lower shell via the connecting pins and the connecting holes, and the structure is simple and the operation is convenient.

[0050] Preferably, the connecting pin is a cylinder with a diameter gradually increasing from top to bottom, and the inner diameter of the connecting hole is smaller than the maximum diameter of the bottom of the cylinder.

[0051] The cylinder with a gradually increasing diameter from top to bottom enables the connecting pin to be tightly connected to the upper shell, thereby preventing the upper shell from being loosened from the lower shell.

[0052] Preferably, a mounting frame is further included, which includes a base plate, a connecting plate is fixed to one end of the base plate, a mounting hole is opened on the connecting plate, the shell is fixedly arranged on the base plate, and the bottom circuit board is located on the side close to the base plate.

[0053] The provision of the mounting bracket facilitates the operator to install the wireless intelligent accelerometer on the monitored object, thereby realizing vibration detection of the detected object.

[0054] Preferably, an antenna is provided on the shell, and one end of the antenna passes through a through hole on the shell and is connected to an interface on the upper circuit board.

[0055] The setting of the antenna improves the communication effect of the wireless communication module, so that the wireless intelligent accelerometer can adapt to complex environments.

[0056] Preferably, the housing is made of plastic or aluminum alloy.
