2. Efficient Data Acquisition: The four-channel design allows the module to collect data from multiple monitoring points at the same time, greatly improving the efficiency and comprehensiveness of data acquisition. In practical applications, sensors at four different positions can be connected simultaneously to obtain vibration and position data during equipment operation in an all-round and real-time manner, avoiding missing potential fault hazards due to single-point monitoring, and providing richer and more comprehensive data support for the overall operation status evaluation of the equipment. Each channel can monitor a wide frequency range, which can cover the frequency range of vibration and position changes of common industrial equipment, ensuring accurate capture of various dynamic information during equipment operation, timely detection of abnormal conditions in equipment operation, and providing strong data support for preventive maintenance of equipment.

Signal Conditioning and Conversion

1. Analog Signal Digitization: The module can quickly and accurately convert analog signals from sensors into digital signals, preparing for subsequent data processing and transmission. In the conversion process, high-precision A/D conversion technology is adopted to ensure that the converted digital signals accurately reflect the characteristics of the original analog signals, effectively avoiding signal distortion. This process is crucial for ensuring data accuracy and provides a reliable data basis for equipment status analysis. By converting analog signals into digital signals, it facilitates the transmission and processing of data in industrial networks, improves data transmission efficiency and anti-interference ability, and enables the equipment monitoring system to evaluate and judge the equipment status more quickly and accurately.

2. Signal Filtering and Amplification: A series of conditioning operations such as filtering and amplification are performed on the collected signals. Through advanced digital filtering algorithms, noise interference in the signals can be effectively removed, signal quality can be improved, and data can more clearly and accurately reflect the actual operating status of the equipment. At the same time, according to actual monitoring needs, the signal is appropriately amplified to enhance the readability and analyzability of the signal. For example, when processing weak vibration signals, through precise amplification operations, the real situation of equipment vibration can be clearly presented, avoiding misjudgment of equipment status due to weak signals. The data after signal conditioning and conversion provides a reliable basis for the realization of equipment protection and early warning functions, ensuring that the equipment can issue alarms in a timely manner when abnormal conditions occur, and ensuring the safe operation of the equipment.

Equipment Protection and Early Warning

1. Real-Time Parameter Comparison and Alarm: One of the core functions of the module is to continuously compare the monitoring parameters with the alarm set points pre-set by the user in the system. Once the monitored data exceeds the preset normal range, the alarm mechanism is quickly triggered. Alarm methods include indicator light flashing, relay output, etc., which can promptly notify operators of abnormal equipment conditions. For example, in vibration monitoring, for the normal vibration range of different equipment, two levels of vibration alarm thresholds, warning and danger, can be set respectively. When the equipment vibration exceeds the warning threshold, an early warning signal is sent to remind operation and maintenance personnel to pay attention to the equipment status; when the vibration reaches the danger threshold, an emergency alarm is immediately issued to urge operators to take emergency shutdown and other measures to prevent further deterioration of equipment failures, effectively protect the safe operation of equipment, and reduce production interruption and economic losses caused by equipment failures.

2. Key Data Collection and Analysis: In addition to the alarm function, 140471-01 is also responsible for collecting key information for equipment operation and maintenance. It can continuously monitor various parameters during equipment operation, and organize and store these data. Through in-depth analysis of these historical data, operation and maintenance personnel can understand the operating trend of the equipment, find potential fault hazards in advance, formulate reasonable maintenance plans, and realize preventive maintenance of the equipment. For example, through trend analysis of the long-term vibration data of the equipment, if it is found that the vibration amplitude has a gradually increasing trend, it may indicate that there are problems such as component wear inside the equipment. At this time, equipment maintenance can be arranged in advance to avoid production interruption caused by sudden equipment failures, reduce enterprise production losses, and improve the reliability and service life of the equipment.
