Description

Technical Field

[0001] This invention belongs to the technical field of smart power distribution equipment for power grids, and specifically relates to a multi-functional smart switchgear for metering boxes based on Internet of Things (IoT) technology. Background Technology

[0002] Metering boxes are core equipment for power system energy metering and distribution control. Their associated switches perform basic functions such as circuit switching and overload protection, and are key components for ensuring electricity safety and accurate metering. Currently, most existing metering box switches are traditional mechanical switches or simple electronic switches, which have several shortcomings: First, they only have local switching capabilities and lack remote control functions, requiring maintenance personnel to operate on-site to start and stop the circuit, resulting in high labor costs and untimely fault response. Second, they lack comprehensive status monitoring capabilities, failing to collect key parameters such as current, voltage, leakage current, and internal temperature and humidity in real time, making it difficult to predict overloads, short circuits, and other electrical faults in advance. First, gas malfunctions can easily lead to electrical safety hazards. Second, the anti-theft protection is weak, lacking a dedicated anti-tampering and abnormal wiring detection structure, allowing criminals to steal electricity through illegal opening of the box and alteration of wiring, resulting in power resource losses that are difficult to trace. Third, the lack of IoT communication capabilities means that equipment operation data cannot be automatically uploaded, relying on manual meter reading and inspection, leading to low maintenance efficiency. Fourth, the single power supply mode means that the equipment completely fails after a power grid outage, making it impossible to retain critical data from before the failure. Therefore, to solve the above problems, it is necessary to develop a well-designed, multifunctional, safe, and convenient multi-functional intelligent switchgear for metering boxes. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a well-designed, multifunctional, safe and convenient metering box intelligent switch device.

[0004] The objective of this invention is achieved as follows: A multi-functional intelligent switchgear for a metering box based on Internet of Things (IoT) technology includes a switch body, a multi-dimensional sensing module, an intelligent control module, an IoT interaction module, and a power supply module. The multi-dimensional sensing module includes a three-phase current sensor, a three-phase voltage sensor, a leakage current detection sensor, a temperature and humidity sensor, a box status sensor, and a wiring temperature sensor, which are used to synchronously collect electrical operating parameters, environmental data, and wiring node status data. The intelligent control module has a built-in data processing chip, a storage unit, and a control program, which are used to receive the data collected by the multi-dimensional sensing module, perform threshold analysis on the data, determine abnormal states, and drive the switch body to execute remote on / off commands. The IoT interaction module has a built-in signal enhancement chip and an anti-interference circuit, which are used to realize bidirectional transmission of commands downlink and data uplink between the intelligent control module and the power operation and maintenance platform. The power supply module adopts dual power supply lines, where the main power supply line draws power from the grid, and the backup power supply line is a supercapacitor plus lithium battery composite power supply structure, which is used to ensure the continuous operation of the core functions of the equipment.

[0005] Furthermore, the enclosure status sensor can detect unauthorized opening actions. It is externally connected to a linkage locking unit and an alarm unit. The linkage locking unit can control the lock cylinder of the switch body to automatically lock, and the alarm unit can send a warning signal to the power operation and maintenance platform.

[0006] Furthermore, the IoT interaction module supports breakpoint resume function, which can automatically resend the unsent data after the network is restored, thereby ensuring data integrity.

[0007] Furthermore, the leakage current detection sensor can monitor the leakage current of the line in real time, and the sensitivity of the leakage current detection sensor is adjustable, with a minimum of 30 mA.

[0008] Furthermore, the multi-dimensional sensing module also includes an abnormal wiring detection unit, which is used to monitor the balance of incoming and outgoing currents and send an alarm signal to the intelligent control module when the current difference exceeds the threshold.

[0009] The beneficial effects of this invention are as follows: By integrating a multi-dimensional sensing module with a three-phase current sensor, a three-phase voltage sensor, a leakage current detection sensor, a temperature and humidity sensor, a cabinet status sensor, a wiring temperature sensor, and an abnormal wiring detection unit, this invention enables comprehensive monitoring of electrical parameters, environmental conditions, cabinet security, and wiring status. This allows for early prediction of various potential electrical hazards and improves the safety of the metering box operation. Furthermore, the dual-power supply module ensures continuous operation of the core functions of the equipment even during power outages. Finally, the inclusion of an IoT interaction module enables intelligent control and integration with the power operation and maintenance platform. The two-way interaction involves uplink transmission of data such as operating parameters, abnormal alarms, and operation records of the metering box equipment, and downlink reception of instructions for remote opening and closing, threshold adjustment, and policy updates. Simultaneously, the IoT interaction module's breakpoint resume function can automatically resend unsent data after network recovery, thus ensuring data integrity. This invention, employing this structure, integrates remote control, multi-parameter monitoring, abnormal early warning, anti-theft protection, and fault self-diagnosis functions, solving the problem of traditional single-function switches and meeting the intelligent operation and maintenance needs of metering boxes in one stop. In summary, this invention has the advantages of a well-designed, multifunctional, and safe and convenient operation. Attached Figure Description

[0011] The present invention will now be further described with reference to the accompanying drawings.

[0012] Example: Figure 1 As shown, a multi-functional intelligent switchgear for metering boxes based on Internet of Things (IoT) technology includes a switch body, a multi-dimensional sensing module, an intelligent control module, an IoT interaction module, and a power supply module. The multi-dimensional sensing module includes a three-phase current sensor, a three-phase voltage sensor, a leakage current detection sensor, a temperature and humidity sensor, a box status sensor, and a wiring temperature sensor, used to synchronously collect electrical operating parameters, environmental data, and wiring node status data. The leakage current detection sensor can monitor leakage current in the line in real time, and its sensitivity is adjustable, with a minimum of 30 mA. The box status sensor can detect unauthorized opening actions and is externally connected to a linkage locking unit and an alarm unit. The linkage locking unit can control the lock cylinder of the switch body to automatically lock, and the alarm unit can send a warning signal to the power operation and maintenance platform. Simultaneously, the multi-dimensional sensing module also includes an abnormal wiring detection unit, used to monitor the balance of incoming and outgoing currents and send an alarm signal to the intelligent control module when the current difference exceeds a threshold. The intelligent control module has a built-in data processing chip, storage unit and control program. It is used to receive data collected by the multi-dimensional sensing module, perform threshold analysis on the data, determine the abnormal state, and drive the switch body to execute remote on / off commands. The IoT interaction module has a built-in signal enhancement chip and anti-interference circuit, which is used to realize bidirectional transmission of commands downlink and data uplink between the intelligent control module and the power operation and maintenance platform; the IoT interaction module supports the function of resuming interrupted transmission, which can automatically resend the unsent data after the network is restored, thereby ensuring the integrity of the data. The power supply module adopts a dual power supply line, with the main power supply line drawing power from the power grid and the backup power supply line using a supercapacitor and lithium battery composite power supply structure to ensure the continuous operation of the core functions of the equipment.

[0013] In use, this invention first comprehensively monitors the electrical parameters, environmental conditions, enclosure security, and wiring status of the metering box equipment through a three-phase current sensor, a three-phase voltage sensor, a leakage current detection sensor, a temperature and humidity sensor, a box status sensor, a wiring temperature sensor, and an abnormal wiring detection unit. During this process, the abnormal wiring detection unit monitors the balance of incoming and outgoing currents and sends an alarm signal to the intelligent control module when the current difference exceeds a threshold. The box status sensor detects unauthorized opening actions and automatically locks the switch body's lock cylinder via its external linkage locking unit. An alarm signal is also sent to the power operation and maintenance platform via its external alarm unit. Then, the collected data is transmitted to the intelligent control module, where its internal data processing chip performs threshold analysis to determine abnormal states. When an abnormality is detected, an alarm is generated. The alarm signal is transmitted to the power operation and maintenance platform. During this process, the IoT interaction module enables bidirectional interaction between the intelligent control module and the power operation and maintenance platform. The uplink transmits data such as the operating parameters, abnormal alarms, and operation records of the metering box equipment, while the downlink receives instructions such as remote opening and closing, threshold adjustment, and policy update. At the same time, the IoT interaction module's breakpoint resume function can automatically resend the unsent data after the network is restored, thereby ensuring data integrity. The power supply module with dual power supply lines can ensure the continuous operation of the core functions of the equipment in the event of a power grid failure. This invention adopts this structure, which integrates remote control, multi-parameter monitoring, abnormal early warning, anti-theft protection, and fault self-diagnosis functions, solving the problem of the single function of traditional switches and meeting the intelligent operation and maintenance needs of metering boxes in one stop. In summary, this invention has the advantages of perfect design, diverse functions, and safe and convenient operation.
