[0018] Example 1 As a preferred embodiment of the present invention: in the hardware information matching module, the hardware of the vibration noise active control system is a noise detector and a vibration sensor, and the identification, information and normal operation values ​​of the noise detector and the vibration sensor are configured and stored; The noise detector uses a microphone or sound pressure sensor to receive sound signals in the environment and convert them into electrical signals. The electrical signals are then amplified and filtered to remove noise and interference, retaining useful sound information. In the digital signal processor, these signals may undergo fast Fourier transform, sampling and storage processing for more in-depth analysis. The processed data, such as the intensity and frequency distribution of the noise, will be displayed on the device's display or transmitted to an external device through the output port. The vibration sensor uses the electrical measurement method to convert the parameters of the engineering vibration into electrical signals, which are displayed and recorded after being amplified by the electronic circuit. The key point of the electrical measurement method is to first convert the mechanical vibration quantity into electrical quantity (electromotive force, charge, and other electrical quantities), and then measure the electrical quantity to obtain the mechanical quantity to be measured. Hardware identification refers to the use of specific methods and technologies to write the unique identification information of the device into the inside or outside of the device during the manufacturing and production process of the test equipment. Hardware information includes processors, memory, input devices, and output devices. The hardware data interval value is the parameter interval value of normal operation.

[0020] Example 3 As a preferred embodiment of the present invention: in hardware operation fault detection, a voltage detector is used to detect the voltage at different phase angles output by the hardware device, and a current detector is used to detect the output current of the hardware device, and the resistance data of the hardware device is calculated based on the voltage and the output current; The voltage monitor is a statistical voltage monitor that continuously monitors and counts the voltage deviation caused by the slow changes in the normal operating state of the power system. It has functions such as monitoring, analysis, memory, query, and parameter setting. Current detection can detect the current in the circuit in real time. Once an abnormal situation occurs, such as current overload or short circuit, the system can immediately take emergency measures, such as power off or alarm, which can effectively avoid accidents and improve the safety of the circuit. The current detector performs real-time self-testing on the operating current of the hardware equipment to verify its normal working state, performance indicators, and safety and reliability. Hardware operation fault detection includes a fault detection board. The fault detection board determines whether the drive control has a fault by detecting whether the output voltage of the pin of the drive control in the hardware device motherboard is at a preset voltage value.

[0021] Example 4 As a preferred embodiment of the present invention: in the operation information comparison and analysis, the processor compares and analyzes the data of the hardware self-test with the data configured in the hardware information matching module to determine whether there is an abnormality in the data, and the storage is used to store the hardware configuration information, self-test data, operation data and fault information; The processor processes the self-test data, compares and analyzes the hardware self-test data with the data configured in the hardware information matching module, and determines whether there is any abnormality in the data. The memory is a memory component used to store programs and various data information. The memory can be divided into two categories: main memory (referred to as main memory or internal memory) and auxiliary memory (referred to as auxiliary memory or external memory). The main memory directly exchanges information with the CPU. The working mode of the main memory is to store or read various types of information according to the address of the storage unit. The storage is used to store hardware configuration information, self-test data, operation data and fault information.

[0022] Example 5 As a preferred embodiment of the present invention: in the execution operation module, according to the detected voltage, current and resistance data, the preset values ​​of the normal operation of the hardware device in the storage are compared and analyzed to obtain the fault data, the controller sends a fault signal, and the data debugging and operation process adjustment of the vibration noise active control system hardware are controlled to achieve the function of real-time adjustment; The operation execution module is used to execute solution generation operation or fault indication operation according to the fault handling strategy database, the feedback indication map and the fault detection result. According to the detected voltage, current and resistance data, the preset values ​​of the normal operation of the hardware equipment in the storage are compared and analyzed to obtain the fault data. The controller sends a fault signal to control the data debugging and operation process adjustment of the vibration and noise active control system hardware to achieve the real-time adjustment function. By executing the operation module, the on-site debugging of the vibration and noise active control system hardware can be reduced. In the controller, the high-heat generating components are installed in a way that they are directly and tightly fitted with a large-area heat dissipation casing. When the equipment is running, the heat can be directly, quickly and efficiently taken away, thereby avoiding heat accumulation or overheating of the components, greatly improving the stability and reliability of the equipment operation, and adopting a fully enclosed structure design, it can adapt well to various complex environments.

[0023] Example 6 As a preferred embodiment of the present invention: in the hardware operating temperature self-check, the temperature sensor regularly self-checks the temperature, analyzes the temperature difference between the inside and outside of the hardware device, and compares and analyzes it with the preset value; The temperature sensor is a non-contact temperature sensor. Its sensitive element does not contact the object being measured. It is also called a non-contact temperature measuring instrument. This instrument can be used to measure the surface temperature of moving objects, small targets, and objects with small heat capacity or rapidly changing temperature. It can also be used to measure the temperature distribution of the temperature field. The upper limit of measurement is not limited by the temperature resistance of the temperature sensing element. Therefore, there is no limit on the maximum measurable temperature in principle. For high temperatures above 1800°C, non-contact temperature measurement methods are mainly used. With the development of infrared technology, radiation temperature measurement has gradually expanded from visible light to infrared, and has been adopted below 700°C and down to room temperature, with high resolution, suitable for temperature detection inside and outside hardware equipment.

When backing up, you only need to copy the changes made to the database since the last backup. The self-check data is updated regularly and transmitted to the backup system through the network. Data processing is inseparable from the support of software. Data processing software includes: various programming languages ​​​​for writing processing programs and their compilers, file systems and database systems for managing data, and application software packages for various data processing methods. In order to ensure the security and reliability of data, there is also a complete set of data security and confidentiality technologies. Data processing is the technical process of analyzing and processing data (both numerical and non-numerical), including the analysis, organization, calculation, editing, etc. of various raw data.
