In the actual test process, if the vibration uniformity of the vibration table cannot be measured in time, the vibration curve requirements cannot be fully simulated; there is currently no good equipment and method for vibration uniformity testing of vibration tables.

[0024] refer to Figure 1 As shown, the utility model provides the following preferred embodiments:

[0025] Embodiment 1

[0026] This embodiment provides a device capable of monitoring the uniformity of a vibration table in real time. The monitoring device mainly includes a plurality of charge-type acceleration sensors, which are attached to the lower end surface of the vibration table to capture vibration data. Each acceleration sensor is electrically connected to a capacitor. Such a configuration helps to convert the charge signal of the sensor into a voltage signal, thereby standardizing the signal processing process.

[0027] Furthermore, the voltage collector connected to the capacitor is responsible for collecting the voltage signals of each capacitor and transmitting these signals to the monitoring PC. This electrical connection ensures efficient and accurate signal transmission, allowing the monitoring PC to perform real-time analysis of the received data to evaluate the uniformity of the vibration table. It can be understood that this layout allows the monitoring system to centrally process vibration data from different points on the vibration table, thereby achieving more accurate vibration uniformity monitoring.

[0028] Through the design and configuration of this embodiment, the monitoring accuracy and response speed of equipment vibration parameters in industrial production can be effectively improved, which helps to adjust industrial processes and equipment maintenance in a timely manner to ensure the optimal state of equipment operation. In addition, this embodiment will also simplify the complexity of equipment operation, reduce the risks caused by uneven equipment vibration, and significantly improve production efficiency and product quality.

[0029] Embodiment 2

[0030] According to the real-time monitoring device for the uniformity of the vibration table described in the above-mentioned embodiment, this embodiment further clarifies the specific number and arrangement of the charge-type acceleration sensors and capacitors in the device to enhance the overall performance and monitoring accuracy of the system. In this embodiment, a total of five charge-type acceleration sensors are used, which are accurately attached to the four corners and the center of the vibration table. This specific layout helps to fully capture the dynamic response of the vibration table in various key areas, thereby providing comprehensive information about the uniformity of vibration.

[0031] Furthermore, the five charge-type accelerometers are electrically connected to five capacitors, and each accelerometer is connected to the voltage collector via a corresponding capacitor. This one-to-one configuration ensures that the signal transmission from each sensor to the voltage collector is direct and interference-free, so that the vibration data of each position can be accurately converted and analyzed.

[0032] Specific steps:

[0033] Attach five charge-type accelerometers to the vibration table. Figure 1 At the five points shown;

[0034] Connect the five charge-type accelerometers to capacitors C1-C5 with equal charge values.

[0035] Connect the five channels of the voltage collector to capacitors C1-C5 respectively;

[0036] The monitoring PC is connected to the voltage collector;

[0037] Start the vibration table and observe the voltage data of the five channels on the monitoring PC.

[0038] It can be understood that this embodiment not only improves the collection accuracy and processing speed of vibration data, but also optimizes the installation and maintenance of the equipment, so that the monitoring device can ensure coverage of key monitoring points while maintaining cost-effectiveness. Through the configuration and technical implementation of this embodiment, the equipment performance monitoring in industrial applications is effectively improved, ensuring the stability of equipment operation and the quality standards of products.

[0039] Embodiment 3

[0040] According to the real-time monitoring device for the uniformity of the vibration table described in the above-mentioned embodiment, this embodiment involves an improved configuration mode of the capacitor, which further enhances the overall performance of the system and the consistency of data processing. In this embodiment, the multiple capacitors used in the monitoring device have equal charge amounts. This design helps to ensure that the charge signals transmitted from each charge-type acceleration sensor have the same starting conditions when converted into voltage signals, thereby ensuring the consistency and comparability of data acquisition.

[0041] Furthermore, by setting all capacitors to have equal charge, the monitoring PC can more easily compare and analyze data when processing these voltage signals without complicated conversion processing. This same standard capacitor configuration simplifies system adjustment and maintenance, reduces errors that may be caused by different capacitor specifications, and improves data processing accuracy and system reliability.

[0042] It is understandable that, although the function can be achieved by using capacitors with unequal charge, capacitors with equal charge can eliminate multiple potential variables in the early stage of system design, making the results more intuitive and reliable. This embodiment uses capacitors with equal charge to help implementers perform fault diagnosis and performance evaluation more quickly, thereby effectively improving operating efficiency and monitoring quality.

[0043] Embodiment 4

[0044] According to the real-time monitoring device for uniformity of the vibration table surface described in the above embodiment, and the configuration of the charge-type acceleration sensor and the capacitor, this embodiment further optimizes the implementation method of voltage acquisition to improve the efficiency and accuracy of data acquisition. In this embodiment, the voltage collector used is designed to have multiple channels, each channel is specially configured to connect a corresponding capacitor. This one-to-one channel-to-capacitor connection design allows the signal generated by each sensor to be collected and processed separately and directly, thereby avoiding interference between signals and data confusion.

[0045] Furthermore, this independent channel design allows the data of each sensor location to be analyzed independently, enhancing the local accuracy of the vibration data and the ability to perceive subtle differences. It should be understood that through this method, operators can more clearly identify possible problems in specific areas, such as different vibration intensities or abnormal frequencies, so as to make targeted adjustments and optimizations.

[0046] It is understandable that this multi-channel voltage collector design not only improves the efficiency of signal processing, but also greatly facilitates the expansion and subsequent upgrade of the monitoring system. This embodiment ensures accurate transmission and effective analysis of monitoring data by adopting a multi-channel voltage collector and a one-to-one connection method, thereby effectively improving the performance and reliability of the vibration monitoring system in practical applications.

[0047] Embodiment 5

[0048] This embodiment further provides an improved capacitor configuration strategy to improve system reliability and spare flexibility of data processing. In this embodiment, the total number of capacitors is designed to be at least one more than the number of charge-type acceleration sensors. This not only allows the system to have spare capacitors to deal with possible equipment failures, but also allows additional capacitors to be configured as reference standards to calibrate or compare the outputs of other sensors.

[0049] Furthermore, by reserving additional capacitor units in the capacitor configuration, data acquisition can be continued without stopping when a sensor or capacitor fails, greatly improving the operational continuity and stability of the device. It should be understood that the additional capacitor can be used to perform system self-calibration, monitor the performance of the entire system, or serve as a benchmark for system stability and efficiency analysis.

[0050] It is understandable that this configuration strategy not only provides higher security and fault tolerance for the operation of the system, but also provides great convenience for maintenance, because the operator can replace or maintain any failed capacitor without interrupting the operation of the system. This embodiment effectively enhances the overall performance and reliability of the real-time monitoring device for the uniformity of the vibration table surface by configuring a larger number of capacitors, thereby ensuring that high-quality and accurate monitoring data can be obtained under various operating conditions.

[0051] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
