[0037] Example

[0038] A low-voltage area terminal sensing device based on dual-mode communication, Figure 1 The overall structural concept diagram of an embodiment of the utility model is shown as follows: Figure 1 As shown, including:

[0039] Control module 1, dual-mode communication module 2, power module 3, data processing module 4, first data acquisition module 5 and second data acquisition module 6;

[0040] The terminal sensing device interacts with the power system data through the dual-mode communication module 2;

[0041] The first data acquisition module 5 is used to collect electrical parameters at the end of the low-voltage area and transmit the electrical parameters to the data processing module 4; the specific content of the first data acquisition module is not limited here, nor is the specific content of the electrical parameters. Optionally, in this embodiment, the first data acquisition module 5 includes a power sensor and a current sensor. The main function of the power sensor is to measure and collect power parameters at the end of the low-voltage area; the current sensor is used to measure and collect current at the end of the low-voltage area. Current is one of the most basic electrical parameters in the power system, and its size directly reflects the operating status and power consumption of each device in the power system;

[0042] The second data acquisition module 6 is used to collect environmental parameters at the end of the low-voltage substation and transmit the environmental parameters to the data processing module 4; the specific content of the second data acquisition module 6 is not limited here, nor is the specific content of the environmental parameters. Optionally, in this embodiment, the second data acquisition module 6 includes a temperature sensor and a humidity sensor; the main function of the temperature sensor is to detect and collect temperature data at the end of the low-voltage substation. It can monitor changes in ambient temperature in real time and reduce the impact of ambient temperature on the power system; the humidity sensor is used to measure and collect humidity data at the end of the low-voltage substation. Humidity is one of the important parameters in the environment and has a certain impact on the operation of the power system and the performance of the equipment. Through the humidity sensor, changes in ambient humidity can be monitored in real time, and excessively high or low humidity can be detected in time, which helps prevent equipment from malfunctioning or being damaged due to humidity problems and ensures the normal operation of the power system;

[0043] The data processing module 4 receives and processes the electrical parameters and environmental parameters, and transmits them to the control module 1; the data processing module 4 first receives the electrical parameters and environmental parameters from the first data acquisition module and the second data acquisition module; after receiving the raw data, the data processing module 4 will perform a series of processing operations. This may include data cleaning, removing noise and abnormal values, formatting, converting data into a unified format and standard, calculation such as calculating power through current and voltage, and data storage to temporarily save data for subsequent use; optionally, in this embodiment, the data processing module 4 processes the electrical parameters and environmental parameters into a unified format;

[0044] The control module 1 outputs the data processed by the data processing module 4 to the power system through the dual-mode communication module 2 .

[0045] Further, in this embodiment, the dual-mode communication module 2 includes a wireless communication submodule, a wired communication submodule, a diagnosis submodule and a communication control submodule;

[0046] The wired communication submodule is electrically connected to the power line, and outputs and receives high-frequency carrier data through the power line. The advantage of power line carrier communication is that it does not require additional communication lines to be laid, and data transmission can be achieved using existing power lines, so it has lower costs and better convenience. Wired communication methods are usually more stable and suitable for most conventional data transmission needs.

[0047] The wireless communication submodule is connected to the base station for communication and outputs and receives data through the base station; it establishes a communication connection with the base station and is responsible for outputting and receiving data wirelessly. The wireless communication method provides an alternative data transmission path when the power line cannot be covered or the wired communication fails;

[0048] The diagnosis submodule determines whether the wired communication submodule is faulty and outputs a determination result;

[0049] The diagnosis submodule is responsible for monitoring the working status of the wired communication submodule and determining whether a fault occurs therein. The submodule further includes a reporting unit, a time unit and a receiving unit.

[0050] Reporting unit: reports the status information of the wired communication submodule to the power system regularly or as needed according to the scheduling of the time unit.

[0051] Time unit: manages the working hours of the reporting unit to ensure that the reporting of status information is neither too frequent nor too sparse to meet the monitoring needs of the power system.

[0052] Receiving unit: responsible for receiving responses or instructions from the power system, which may be confirmation of reported data, query or configuration change, etc.

[0053] The communication control submodule controls the wired communication submodule or the wireless communication submodule to transmit according to the judgment result; if the diagnosis submodule determines that the wired communication submodule is normal, the communication control submodule gives priority to using the wired communication method for data transmission; if the wired communication submodule fails, the communication control submodule will switch to the wireless communication submodule for data transmission to ensure the continuity and reliability of the data.

[0054] Furthermore, the wireless communication submodule includes a LoRa communication interface and a NB-IoT communication interface. By integrating the two communication interfaces of LoRa and NB-IoT, the wireless communication submodule can flexibly select the most suitable communication method according to different application scenarios and requirements. For example, in applications that require self-built networks and low costs, the LoRa communication interface can be selected; while in applications that require wide coverage, high reliability and operator support, the NB-IoT communication interface can be selected. This design improves the adaptability and reliability of the wireless communication submodule, enabling it to better meet the data transmission requirements in various complex environments.

[0055] Furthermore, in this embodiment, a storage module 7 is also included for storing historical electrical parameters and historical environmental parameters. The storage module 7 provides a reliable guarantee for the long-term preservation of the data of the low-voltage station terminal sensing device, and also provides strong support for the troubleshooting, optimization decision-making and cost control of the power system;

[0056] Furthermore, in this embodiment, a data buffer module 8 is also included, and the data buffer module is connected to the control module and the dual-mode communication module, and is used to store data transmitted by the power system to the terminal sensing device through the dual-mode communication module. During the data transmission process, due to network delays, communication failures or other reasons, the data receiving speed may temporarily not keep up with the sending speed. The existence of the data buffer module 8 can effectively alleviate this transmission pressure and ensure that data will not be lost due to untimely reception. When processing data, the terminal sensing device needs to ensure the continuity and integrity of the data. The data buffer module 8 can ensure that when the data processing module is busy processing other tasks, the newly received data will not be omitted or overwritten, thereby ensuring the continuity of data processing.

[0057] Further, the power module 3 includes a wide voltage input circuit, a power conversion circuit and a protection circuit; a wide voltage design is adopted; the wide voltage design means that the power module 3 can work normally within a wider voltage range. This is particularly important for devices used in different regions or different power environments, because the voltage standards in different places may be different. Through the wide voltage design, the power module 3 can better adapt to these changes and ensure the stable operation of the equipment. The power module 3 with a wide voltage design can be compatible with more types of equipment and systems. Whether in a home, industrial or commercial environment, the voltages required by various devices and systems may be different. The wide voltage design enables the power module 3 to meet the needs of these different devices and improves the versatility and flexibility of the equipment. There may be voltage fluctuations in the power system, which will affect the normal operation of the equipment. The power module 3 with a wide voltage design can better cope with these voltage fluctuations and maintain the stability of the output voltage, thereby protecting the equipment from damage or failure caused by voltage fluctuations.

[0058] Furthermore, it also includes a self-diagnosis module 9, which monitors the working status of each module in real time and sends working status information to the power system through the dual-mode communication module. The self-diagnosis module 9 can monitor the working status of each module in real time, including the power module, the communication module, the storage module, etc. Through real-time monitoring, potential faults or abnormal conditions can be discovered in time, so that measures can be taken quickly to prevent or repair them, so as to avoid the expansion of faults or affecting the normal operation of the entire system.

[0059] By integrating the first data acquisition module and the second data acquisition module, the terminal sensing device can simultaneously collect the electrical parameters and environmental parameters of the low-voltage substation terminal, thereby greatly improving the efficiency of data acquisition. The application of the dual-mode communication module makes the terminal sensing device more flexible and reliable in data transmission. Whether through power line carrier communication or wireless communication, the stability and security of data during transmission can be ensured, effectively avoiding the transmission bottleneck and failure risks that may be caused by a single communication method; through data interaction with the power system, the terminal sensing device can realize remote monitoring and management functions.
