[0044] Please refer to Figure 1 - Figure 6 One embodiment of the present utility model provides a signal detection system 300, characterized in that the signal detection system 300 includes: a housing 10, a circuit board 20, a vibration sensor 30, a data processor 21 and a security chip 22.

[0045] The circuit board 20 is disposed in the housing 10. The vibration sensor 30 is disposed in the housing 10 and is electrically connected to the circuit board 20. The vibration signal in the construction project is collected by the vibration sensor 30. The data processor 21 is integrated on the circuit board 20 and is data-connected to the vibration sensor 30. The security chip 22 is integrated on the circuit board 20 and is data-connected to the data processor 21. The vibration data in the data processor 21 is encrypted and calculated in sequence by the security chip 22, and the vibration data in the calculation is in an encrypted state to protect data privacy.

[0046] The data processor 21 and the security chip 22 are integrated on the same circuit board 20, which helps to simplify the design and assembly of the device, reduce the number and complexity of components in the system, and improve the overall reliability and stability of the device. The components integrated on the circuit board 20 can be maintained and managed more easily, reducing the connections and interfaces in the system, reducing the failure rate, and improving the stability and maintainability of the system. The vibration sensor 30 is directly installed inside the housing 10 and connected to the circuit board 20, which simplifies the installation process, reduces the connection lines between the circuit board 20 and the vibration sensor 30, and improves the installation efficiency of the system.

[0047] Among them, the way the security chip 22 encrypts the vibration data is homomorphic encryption. In homomorphic encryption technology, decryption is usually performed after the calculation is completed. This is a key feature of homomorphic encryption, which allows data to be calculated in an encrypted state without decrypting the data first. Only when the calculation result is finally obtained, the result needs to be decrypted to obtain the original plaintext result. In this way, calculations and processing can be performed without exposing the original data, while ensuring the privacy and security of the data.

[0048] More preferably, the housing 10 includes a lower housing 11 and an upper housing 12 .

[0049] The circuit board 20 is located on the lower housing 11. The upper housing 12 is located on a side of the circuit board 20 away from the lower housing 11, and the upper housing 12 is connected to the lower housing 11. A power supply unit 40 is provided on the lower housing 11, and the power supply unit 40 is electrically connected to the vibration sensor 30, and the power supply unit 40 supplies power for the operation of the signal detection system 300.

By placing the circuit board 20 on the lower housing 11 and making the upper housing 12 face away from the lower housing 11, the layout of the entire system can be made more neat and compact. The space between the upper and lower housings 11 can be used to install other components or circuits, improving the flexibility and scalability of the system. A power supply unit 40 is provided on the lower housing 11, which can provide the power supply required for the operation of the entire signal detection system 300. The power supply unit 40 is electrically connected to the vibration sensor 30 to ensure the power supply required for the normal operation of the sensor, and also provides power for other components to ensure the normal operation of the entire system. Installing the power supply unit 40 on the lower housing 11 makes it easier to maintain and replace the power supply components.

When observing in a direction perpendicular to the surface of the display 70, the button 80 is arranged side by side with the display 70 on the upper housing 12, and the user inputs operation instructions through the button 80.

[0053] Among them, the display 70 and the buttons 80 are arranged side by side on the surface of the upper housing 12, enabling the user to conveniently observe the vibration data on the display 70 and input operation instructions through the buttons 80. This layout design makes the user operation more intuitive and convenient, improving the usability and user experience of the system. Arranging the display 70 and the buttons 80 on the surface of the upper housing 12 can effectively utilize the space of the device, making the size of the entire system more compact. At the same time, when observing along the direction perpendicular to the surface of the display 70, both the display 70 and the buttons 80 are located on the same plane, making the appearance of the device more tidy and beautiful. By arranging the buttons 80 side by side with the display 70 on the upper housing 12, it can prevent the user from accidentally touching the buttons 80 or affecting the normal use of the display 70 during the operation process. This layout design improves the stability and reliability of the system and reduces the risk of misoperation. Placing the display 70 in a position where the user can easily observe and operate it enables the user to intuitively understand the vibration data situation and perform corresponding operations and adjustments through the buttons 80. This setting improves the user's control ability over the system functions and enhances the user's use experience and satisfaction.

[0054] More preferably, the signal detection system 300 further includes: a wireless adapter 23. The wireless adapter 23 is integrated on the circuit board 20 and is located on the side of the security chip 22 away from the data processor 21.

This can facilitate data transmission and communication between the device and the server, avoiding the limitations and inconveniences brought by using traditional wired connection methods. Placing the wireless adapter 23 on one side of the security chip 22 can optimize the layout on the circuit board 20, making the structure of the entire system more compact and reasonable. At the same time, this position setting can also reduce the interference between the wireless signal and other components, improving the stability and reliability of the system. By connecting the wireless adapter 23 to the security chip 22, the security of the data transmission and communication process between the device and the cloud server 60 can be ensured. The security chip 22 can encrypt the data to protect the privacy and security of the data and prevent the data from being accessed and stolen by unauthorized personnel. The user's client 50 can conveniently obtain the data and information uploaded by the device through the wireless connection with the cloud server 60. This setting enables the user to view the operating status and vibration data situation of the signal detection system 300 through the client 50 at any time and place, improving the convenience and use experience of the user.

[0056] Preferably, the security chip 22 is wirelessly connected to the client 50. The client 50 authenticates the user identity through the security chip 22, and the security chip 22 authorizes the user with correct identity.

[0057] Among them, by establishing a wireless connection between the security chip 22 and the client 50, the user identity authentication function can be realized. The security chip 22 can authenticate the user's identity to ensure that only users with correct identity can access the data and functions in the device or system, thereby improving the security and reliability of the system. The security chip 22 can authorize the users who pass the identity authentication to allow them to access the data and functions in the device or system. This setting can effectively protect the security of data, prevent unauthorized users from accessing and stealing data, and protect the privacy and confidentiality of data. By establishing a wireless connection with the security chip 22, the client 50 can conveniently perform user identity authentication and authorization operations without using complex wired connection methods. This setting improves the convenience and flexibility of user operations and enhances the user experience. The security chip 22 can authenticate the user's identity in real time and perform corresponding authorization operations according to the authentication results. This setting can respond to the user's operation requests in a timely manner, ensure the security and stability of the device or system, and provide more reliable services for users.

[0058] Preferably, for authorized users, the encrypted vibration data is decrypted by the cloud server 60 and transmitted to the client 50 of the authorized user.

[0059] Among them, by decrypting the vibration data on the cloud server 60 and transmitting it to the client 50 of the authorized user, the security of the data before being transmitted to the cloud server 60 can be ensured. Since the vibration data is in an encrypted state during the transmission process, only users who have passed the identity authentication and are authorized can decrypt and obtain the data, thereby protecting the privacy and confidentiality of the data. Transmitting the decrypted vibration data to the client 50 of the authorized user can realize real-time data access and monitoring. The authorized user can view the vibration data of the device at any time and place through the client 50, and timely understand the operating status of the device, improving the timeliness and availability of the data. By transmitting the decrypted data to the client 50, it is convenient for the authorized user to directly view and analyze the data on their own device without having to log in to the cloud server 60 for operations. This setting improves the convenience and experience of users and enhances the user's satisfaction with the system. Transmitting the decrypted data to the client 50 can facilitate the user to further manage and process the data, such as storage, analysis, export and other operations. This setting helps the user to better utilize the data and improve the value and application scope of the data.

[0060] Preferably, when observing in a direction perpendicular to the circuit board 20, the data processor 21, the security chip 22, and the wireless adapter 23 are arranged on the circuit board 20, and the security chip 22 is located between the data processor 21 and the wireless adapter 23.

[0061] Among them, arranging the data processor 21, the security chip 22, and the wireless adapter 23 along a direction perpendicular to the circuit board 20 can maximize the utilization of the space on the circuit board 20, achieving a compact and efficient layout. This layout design can effectively save the space of the device, making the size of the entire system more compact, while also improving the integration and performance density of the circuit board 20. The security chip 22 can both perform data connection with the data processor 21 to implement data encryption and decryption operations, and perform data connection with the wireless adapter 23 to implement data transmission and communication functions. This setting makes the circuit design of the entire system more reasonable and optimized, and this setting can improve the data transmission efficiency and communication rate, reduce the delay and loss during data transmission, and improve the performance and response speed of the system. Arranging the data processor 21, the security chip 22, and the wireless adapter 23 on the circuit board 20 also makes the connection between these components clearer and simpler, facilitating the maintenance and repair of the device. When these components need to be replaced or repaired, the operation can be carried out more conveniently, improving the maintainability of the system.

[0062] Preferably, the data processor 21 includes: a signal receiver 211 and an analog-to-digital converter 212. The signal receiver 211 is electrically connected to the circuit board 20, and the vibration signal collected by the vibration sensor 30 is received through the signal receiver 211.

Such a setting can ensure the stable acquisition and transmission of the signal, reduce signal loss and interference, and improve the accuracy and reliability of the data. It is responsible for converting the analog signal into a digital signal to achieve signal sampling and quantization. Through the function of the analog-to-digital converter 212, the continuous analog signal can be converted into a discrete digital signal, enabling the signal to be digitally processed and analyzed by the processor. Such a setting can ensure the precise sampling and quantization of the vibration data, and improve the processability and reliability of the data.
