Description

Technical Field

[0001] This invention relates to the field of power monitoring technology, and more specifically, to a primary and secondary integrated ring network box status monitoring system. Background Technology

[0002] Ring main units are important equipment in power systems, and their operating status directly affects the safety and stability of the power system.

[0003] Traditional ring main unit (RMU) condition monitoring systems typically require external power. However, in complex environments, power lines are easily damaged, causing the monitoring system to malfunction. This necessitates regular inspection and maintenance of the power supply equipment, significantly increasing maintenance costs. Furthermore, traditional monitoring systems, limited by power supply constraints, struggle to achieve long-term stable online monitoring and fail to promptly detect potential faults in the RMU, potentially leading to serious power outages. Therefore, we propose a primary and secondary integrated RMU condition monitoring system. Summary of the Invention

The wireless communication module is connected to the sensor module and is used to wirelessly transmit the parameter data monitored by the sensor module to realize remote monitoring and management. The energy management module is connected to the vibration energy harvester, sensor module, and wireless communication module, respectively, and is used to manage and distribute the electrical energy generated by the vibration energy harvester, rectify and regulate the electrical energy, and store it according to the formula. Power is allocated to the sensor module and the wireless communication module, where, This is the power distribution factor. The electrical energy collected by the vibration energy harvester The energy storage efficiency of the energy storage unit. This represents the energy consumption of the sensor module per unit time. For the sensor module's operating time, This represents the energy consumption of the wireless communication module per unit time. This refers to the operating time of the wireless communication module.

[0006] Preferably, the sensor module includes a low-power temperature sensor, a humidity sensor, a vibration sensor, and a current sensor.

[0007] Preferably, the sensor module further includes a data preprocessing unit for filtering and noise reduction of the monitored temperature, humidity, vibration, and current parameters, removing interference signals, and improving the accuracy of the parameter data.

[0008] Preferably, the wireless communication module has an adaptive transmission rate adjustment function. When the parameters in the ring network box are detected to be within the normal range, the transmission rate is automatically reduced to reduce energy consumption. When the parameters are abnormal, the transmission rate is automatically increased to ensure that abnormal information is transmitted quickly.

[0009] Preferably, the energy management module includes a priority determination unit, which allocates power according to the order in which the sensor module takes precedence over the wireless communication module when the stored power is insufficient.

[0010] Preferably, it also includes a local early warning module, which is connected to the sensor module. When the parameters inside the ring network box detected by the sensor module exceed the safety threshold, an early warning is issued locally in the ring network box through an audible and visual alarm signal.

[0011] Preferably, the energy management module further includes an energy storage unit for storing electrical energy. The energy storage unit uses a hybrid energy storage system of supercapacitors and lithium batteries, which are dynamically switched by the energy management module to ensure power supply continuity.

[0012] Preferably, the wireless communication module supports multi-protocol adaptation and is compatible with LoRa and NB-IoT low-power wide-area network communication protocols.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention converts the vibration energy generated by the operation of equipment inside the ring main unit into electrical energy through a vibration energy harvester. It does not require external power supply, thus avoiding the problem of monitoring system failure caused by the easy damage of power supply lines in complex environments. It also reduces the work of staff to regularly inspect and maintain the power supply equipment, thereby reducing maintenance costs. At the same time, it eliminates the limitations of power supply and enables long-term stable online monitoring. It can detect potential faults in the ring main unit in a timely manner and effectively avoid serious power accidents caused by failure to deal with faults in a timely manner.

[0014] 2. This invention comprehensively monitors key parameters within the ring network enclosure and is equipped with a data preprocessing unit to filter and reduce noise in the monitoring data, effectively removing interference signals and improving the accuracy of parameter data. The wireless communication module has an adaptive transmission rate adjustment function, which automatically reduces the transmission rate to reduce energy consumption when parameters are normal and automatically increases the transmission rate to ensure rapid information transmission when parameters are abnormal. This balances energy-saving requirements with the timeliness of data transmission, enabling the system to perceive the operating status of the ring network enclosure more accurately and efficiently.

[0015] 3. This invention calculates the power distribution coefficient based on a formula, and combines the unit energy consumption and working time of the sensor module and the wireless communication module to accurately allocate power to both, avoiding energy waste. At the same time, the module includes a priority judgment unit. When the stored power is insufficient, power is allocated according to the order of priority of the sensor module over the wireless communication module, ensuring that the core monitoring function is not interrupted. This maximizes the system's operating efficiency under limited energy conditions and improves the rationality and reliability of energy utilization. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the system architecture in this invention. Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0018] A primary and secondary integrated ring network cage condition monitoring system, comprising a vibration energy harvester, a sensor module, a wireless communication module, and an energy management module; The vibration energy harvester is installed inside the ring main unit and in contact with the equipment inside the ring main unit. It is used to convert the vibration energy generated by the operation of the equipment into electrical energy to achieve energy self-sufficiency, reduce dependence on external power supply, and is suitable for ring main unit scenarios where wiring is difficult. It reduces operation and maintenance costs and at the same time uses the vibration of the equipment itself to generate electricity, thereby improving energy utilization efficiency. Sensor modules are installed in different locations inside the ring main unit to monitor the temperature, humidity, vibration, and current parameters of the ring main unit in real time. By monitoring multiple parameters, the operating status of the ring main unit can be fully understood, and potential faults such as overheating, humidity, abnormal vibration, or current fluctuations can be detected in a timely manner, providing data support for condition assessment. The wireless communication module connects to the sensor module to wirelessly transmit the parameter data monitored by the sensor module, enabling remote monitoring and management. Wireless transmission avoids complex wiring, reduces system installation difficulty and cost, and supports remote real-time monitoring of the ring network box status, facilitating timely scheduling and maintenance. The energy management module is connected to the vibration energy harvester, sensor module, and wireless communication module, respectively. It manages and distributes the electrical energy generated by the vibration energy harvester, rectifies and regulates the electrical energy, and stores it according to the formula... Power is allocated to the sensor module and the wireless communication module, where, This is the power distribution factor. The electrical energy collected by the vibration energy harvester The energy storage efficiency of the energy storage unit. This represents the energy consumption of the sensor module per unit time. For the sensor module's operating time, This represents the energy consumption of the wireless communication module per unit time. The power distribution ratio is quantified by a formula to ensure that the collected power is distributed to the sensors and communication modules as needed for the working time of the wireless communication module. Rectification and voltage regulation ensure power supply stability, and energy storage function avoids power outages caused by vibration energy fluctuations, thereby improving the system's endurance.

[0019] Furthermore, the sensor module includes low-power temperature sensors, humidity sensors, vibration sensors, and current sensors to comprehensively monitor the parameters of the ring network box.

[0020] Furthermore, the sensor module also includes a data preprocessing unit, which is used to filter and reduce noise in the monitored temperature, humidity, vibration, and current parameters, remove interference signals, and improve the accuracy of parameter data. This helps to avoid misjudgments caused by data errors and provides a reliable basis for subsequent early warning and decision-making.

[0021] Furthermore, the wireless communication module has an adaptive transmission rate adjustment function. When the parameters in the ring network box are within the normal range, it automatically reduces the transmission rate to reduce energy consumption. When the parameters are abnormal, it automatically increases the transmission rate to ensure that the abnormal information is transmitted quickly. This dynamically adjusts the transmission rate to balance energy consumption and real-time performance, reducing power consumption under normal conditions and prioritizing the rapid uploading of information during abnormal conditions to ensure timely fault response.

[0022] Furthermore, the energy management module includes a priority judgment unit. When the stored power is insufficient, power is allocated according to the order of sensor modules over wireless communication modules to ensure that the core monitoring function is not interrupted and to guarantee the continuity of basic status monitoring.

[0023] Furthermore, it also includes a local early warning module, which is connected to the sensor module. When the parameters inside the ring network box detected by the sensor module exceed the safety threshold, an early warning is issued locally in the ring network box through an audible and visual alarm signal. Local early warning can quickly remind nearby staff to handle emergencies, make up for the response delay that may exist in remote monitoring, and improve the efficiency of fault handling.

[0024] Furthermore, the energy management module also includes an energy storage unit for storing electrical energy. The energy storage unit uses a hybrid energy storage of supercapacitors and lithium batteries. The two are dynamically switched through the energy management module to ensure power supply continuity. The supercapacitors charge and discharge quickly to cope with instantaneous fluctuations in vibration energy, while the lithium batteries store energy for a long time. The combination of the two ensures stable power supply and avoids the limitations of a single energy storage method.

[0025] Furthermore, the wireless communication module supports multi-protocol adaptation and is compatible with LoRa and NB-IoT low-power wide-area network communication protocols to ensure stable communication in different geographical and network environments and improve system applicability.

[0026] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
