Description

Technical Field

[0001] The utility model relates to the technical field of data acquisition, and particularly relates to an Ethernet wired data acquisition device. Background Art

[0002] Data acquisition refers to the process of obtaining information and data from various data sources. It is an important pre-step for data analysis, processing, and application. Through appropriate technologies and tools, data distributed in different locations, in different formats, and from different sources are collected to provide basic support for subsequent analysis, mining, and decision-making.

[0003] In existing data acquisition systems, wireless public network data acquisition units often cannot ensure stable data transmission in areas with weak signals or severe signal shielding (such as basements, high-rise dense areas, etc.). However, in some places, mobile signals cannot penetrate deep basements or some areas with extremely severe signal shielding, and the signal rapidly weakens until it reaches zero. Even by methods such as replacing high-gain antennas, extending antennas, and adjusting the installation direction, normal communication still cannot be achieved. Moreover, due to the attenuation of wireless signals when penetrating buildings, in cities with dense residents, wireless public networks do not have an advantage in solving the problem of weak signals. Therefore, an Ethernet wired data acquisition device is proposed. Summary of the Utility Model

[0025] The data conversion unit, the data transmission unit, and the data transceiver unit are connected by optical fiber and Ethernet connection lines;

[0026] The data conversion unit includes an MCU (microcontroller), an Ethernet chip, a GPRS / CDMA / 3G / 4G module, a power supply module, an interface circuit, and a storage module; among them, the MCU is connected to the Ethernet chip and the GPRS / CDMA / 3G / 4G module through an SPI interface and is used to control data processing and conversion; the GPRS / CDMA / 3G / 4G module is used to receive control signals from the master station, convert them into the format for Ethernet transmission, and convert the data from the data transceiver unit into the format for sending through the GPRS / CDMA / 3G / 4G network; the interface circuit includes an Ethernet interface and an optical fiber interface, which are respectively used to connect Ethernet signals and optical fiber signals with the data transmission unit; the power supply module is used to provide a stable working voltage for the entire device;

[0028] The data transceiver unit has an Ethernet interface and a terminal interface and is used to receive data from the data transmission unit and perform corresponding processing or forwarding; the data transceiver unit is also used to send the data that needs to be uploaded to the master station to the GPRS / CDMA / 3G / 4G module through the data transmission unit and the data conversion unit.

[0029] In one embodiment, specifically: the interface circuit is specifically an RJ45 Ethernet interface and an ST / SC optical fiber interface, which are used for data transmission with external devices or networks. By adopting the RJ45 Ethernet interface and the ST / SC optical fiber interface, different types of external devices or networks can be flexibly accessed to achieve efficient and stable data transmission. The combined use of these two interfaces not only improves the communication ability of the device but also enhances its adaptability and scalability.

[0030] In one embodiment, specifically: The storage module is an erasable programmable read-only memory (EEPROM) for storing the configuration information, historical data, or firmware upgrade files of the device. The EEPROM can store the configuration information of the device for a long time, such as network settings, communication protocol parameters, data acquisition frequency, etc. These configuration information are read when the device starts up and used to initialize the operating parameters of the system, ensuring that the device can collect and transmit data according to the predetermined configuration.

[0031] In one embodiment, specifically: The control circuit in the data transmission unit includes an MPU (microprocessor). The MPU communicates with the optoelectronic conversion module, Ethernet interface circuit, and fiber optic interface circuit through the I2C interface. By using the MPU as the control core of the data transmission unit and communicating with the optoelectronic conversion module, Ethernet interface circuit, and fiber optic interface circuit through the I2C interface, the Ethernet wired data acquisition device realizes the precise control and management of the data transmission process. Specifically:

[0032] The MPU decides which interface the data should be transmitted through according to the destination and type of the data. For example, if the data needs to be sent through Ethernet, the MPU will instruct the Ethernet interface circuit to prepare to receive the data; if the data needs to be sent through fiber optic, the MPU will control the optoelectronic conversion module to perform corresponding operations.

[0033] The MPU can monitor the working status of each interface circuit in real time, including data transmission rate, error rate, connection status, etc. Once an abnormal situation is detected, the MPU can immediately take measures to intervene, such as retrying the transmission, switching the interface, or reporting an error.

[0034] The MPU is also responsible for managing and configuring the parameters of the data transmission unit, such as interface rate, communication protocol, data packet format, etc. These configuration information can be adjusted according to actual needs to meet the requirements of different application scenarios.

[0035] In one embodiment, specifically: the MCU is the HT6019 single-phase smart meter dedicated chip, and the Ethernet chip is the W5500 Ethernet chip. Among them, the HT6019 chip is responsible for processing the power metering tasks in the data acquisition device, including the measurement and calculation of parameters such as voltage, current, power, and electric energy. At the same time, it also interacts with external circuits (such as optical-electric conversion modules, storage modules, etc.) through the internally integrated communication interfaces (such as SPI, UART, etc.) to achieve data transmission and storage; the W5500 Ethernet chip is responsible for realizing the Ethernet communication between the data acquisition device and the external network. It is connected to the MCU through the SPI interface, receives data packets from the MCU, and encapsulates them into data frames conforming to the Ethernet protocol and sends them out. At the same time, the W5500 chip can also receive data frames from the external network, unpack them, and transmit them to the MCU through the SPI interface for processing; by selecting the HT6019 single-phase smart meter dedicated chip and the W5500 Ethernet chip as the core components, the Ethernet wired data acquisition device realizes the accurate metering of single-phase electric energy and efficient network communication. This design not only improves the accuracy and real-time performance of data acquisition, but also enhances the reliability and stability of the device.

[0036] In one embodiment, specifically: the data conversion unit further includes a temperature sensor. The temperature sensor is used to monitor the internal temperature of the device and send the temperature information to the data transmission unit after being processed by the MCU. By adding the temperature sensor, the Ethernet wired data acquisition device realizes the real-time monitoring and intelligent management of the internal temperature. This improvement not only improves the reliability and stability of the device, but also provides users with more comprehensive and convenient remote monitoring means.

[0037] In one embodiment, specifically: the data transceiver unit further includes a data processing module. The data processing module is used to preprocess the received data, including data filtering, compression, or encryption. By adding the data processing module, the data transceiver unit of the Ethernet wired data acquisition device has stronger data processing capabilities. The data processing module can perform preprocessing operations such as data filtering, compression, and encryption to improve the accuracy, security, and efficiency of the data.

[0038] In one embodiment, specifically: it further includes a fault diagnosis module. The fault diagnosis module is connected to the MCU and is used to monitor the working status of each module inside the device and automatically start the fault diagnosis program when a fault is detected, and send the fault information to the remote monitoring center through the data transmission unit. By adding the fault diagnosis module, the Ethernet wired data acquisition device has stronger self-monitoring and fault troubleshooting capabilities.

[0039] When the utility model is working:

[0040] From the master station to the terminal: The master station sends control signals or data requests to the data conversion unit through the GPRS / CDMA / 3G / 4G network. The GPRS / CDMA / 3G / 4G module of the data conversion unit receives these signals and converts them into digital signals suitable for internal processing. The MCU controls the Ethernet chip to convert the received digital signals into Ethernet signals and sends them to the data transmission unit through the interface circuit (Ethernet interface). The optical and electrical conversion module of the data transmission unit converts the Ethernet signals into optical fiber signals and transmits them to the data transceiver unit through the optical fiber. The data transceiver unit receives the Ethernet signals converted by the optical fiber converter through the Ethernet port. The data processing module in the data transceiver unit further processes the received data, such as data filtering, compression, parsing, etc., stores the data locally or forwards it to other systems as needed. The terminal device (such as a smart meter, sensor, etc.) obtains the required data through the data transceiver unit for real-time processing or storage;

[0041] From the terminal to the master station: The terminal device sends the data to be uploaded to the data transmission unit through the Ethernet port of the data transceiver unit. The optical and electrical conversion module of the data transmission unit converts the received Ethernet signals back into optical fiber signals and transmits them to the data conversion unit through the optical fiber. The Ethernet chip of the data conversion unit converts the optical fiber signals back into Ethernet signals, and the MCU controls the GPRS / CDMA / 3G / 4G module to send these data back to the master station through the GPRS / CDMA / 3G / 4G network. The master station receives and processes these data for monitoring, analysis, or further issuing control instructions;

[0042] During the whole working process, the fault diagnosis module monitors the working states of each unit in real time, including communication states, data processing speeds, hardware temperatures, etc. Once an abnormality or fault is detected, the fault diagnosis module will trigger the corresponding alarm mechanism and send the fault information to the remote monitoring center through the data transmission unit and the data conversion unit.

Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered by the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
