Description

Technical Field

[0001] This utility model belongs to the field of intelligent power distribution network technology, specifically relating to a small water pump control system for intelligent power distribution rooms. Background Technology

[0002] Currently, in the water sump of the power distribution room (or transformer substation), the traditional water pump control circuit uses a thermal overload relay and contactor in the main circuit, and a button to control the relay in the auxiliary control circuit to control the start and stop of the water pump.

[0003] When the main station needs to remotely control and monitor the water pump, the commonly used control methods have some drawbacks. The data collected on the equipment's operating status may not be accurate. The local and remote control of the control loop are essentially controlled by relays, which control the start and stop of the water pump. However, when the relay is energized, the main station assumes that the equipment has started, but in reality, the equipment may not be running. There may also be situations where the relay is energized but the equipment is not running. The data collected on the power failure signal may not be accurate. Currently, many main stations collect the signal of power failure by adding an auxiliary point at the circuit breaker. When the circuit breaker is deactivated, the signal of power failure is uploaded. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent power distribution room small water pump control system, aiming to solve the problem of inaccurate data acquisition of equipment operation status in existing technologies. It mainly addresses the issues of inaccurate signals acquired by the master station for AC power loss, pump start-up, pump stop-up, successful pump start-up, failed pump start-up, successful pump stop-up, and failed pump stop-up, as well as the inconsistency between the signals acquired by the master station and the pump's operating status.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A smart power distribution room small water pump control system includes: The Internet of Things (IoT) intelligent miniature circuit breaker possesses the protection, measurement, early warning, flexible networking, manual / automatic operation, and fire alarm linkage functions of a conventional circuit breaker. The measurement functions include measuring voltage, current, power, and leakage current. The warning functions include current warning, voltage warning, power warning, and leakage warning; The flexible networking function supports networking via RS5 communication, Bluetooth, wireless, or Wi-Fi modes. The IoT-enabled smart miniature circuit breaker can communicate with the power distribution room or box-type dynamic loop system or DTU, and upload its own data to the background management system. The IoT-enabled smart miniature circuit breaker is used to directly control the start and stop of small water pumps without the need for additional contactor control circuit design.

[0006] As a preferred embodiment of this utility model, the IoT smart miniature circuit breaker can perform opening and closing operations through its own operating handle, and can receive remote control commands from the master station to execute the start and stop of the water pump during remote operation.

[0007] As a preferred embodiment of this utility model, when the power supply voltage disappears, the IoT smart miniature circuit breaker can automatically report an AC power failure signal; when a normal load current is detected, it reports a water pump start signal; if no load current is detected, it reports a water pump start failure signal.

[0008] As a preferred embodiment of this utility model, the system also includes a fault detection mechanism, which can automatically report a fault signal when the miniature circuit breaker trips but there is still load current.

[0009] As a preferred embodiment of this utility model, the IoT smart miniature circuit breaker has an electrical life of 6,000 cycles, which is suitable for the infrequent start-stop requirements of water pumps and does not require additional equipment to extend its service life.

[0010] As a preferred embodiment of this utility model, the system simplifies the design of the secondary control loop. It only requires connecting the communication line to the host computer to realize manual and remote control functions, thereby reducing the complexity and maintenance cost of the system.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this solution, the power supply voltage and load current are directly monitored through IoT-enabled smart miniature circuit breakers, solving the misjudgment problem caused by relays or circuit breaker auxiliary points in traditional control circuits. The system can provide real-time feedback on the actual operating status of the water pump, ensuring the accuracy of the data received by the master station. Simultaneously, the fault detection mechanism can automatically identify abnormal situations, significantly improving fault response speed and avoiding maintenance delays caused by false alarms or missed alarms, thereby enhancing the safety of the drainage system in the power distribution room (or transformer substation).

[0012] 2. This solution employs highly integrated IoT-enabled smart miniature circuit breakers, replacing the traditional complex secondary control circuits. Local and remote control can be achieved simply by connecting to a host computer via a communication cable. This design significantly reduces the number of components and wiring complexity, lowering hardware costs and installation difficulty. Furthermore, the miniature circuit breakers have a 6000-cycle electrical life, fully meeting the pump start-up and shutdown requirements without the need for additional equipment, reducing maintenance workload and long-term operation and maintenance costs. The overall solution enhances the level of intelligence while achieving a dual optimization of structural simplification and economic efficiency, making it suitable for upgrading drainage systems in various intelligent power distribution rooms (or intelligent transformer substations).

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1

[0016] Please see Figures 1-2 The present invention provides the following technical solution: A smart power distribution room small water pump control system includes: The Internet of Things (IoT) smart miniature circuit breaker possesses the protection, measurement, early warning, flexible networking, manual / automatic operation, and fire alarm linkage functions of a conventional circuit breaker. The measurement functions include measuring voltage, current, power, and leakage current. The warning functions include current warning, voltage warning, power warning, and leakage warning; The flexible networking function supports networking via RS5 communication, Bluetooth, wireless, or Wi-Fi modes. The IoT-enabled smart miniature circuit breaker can communicate with the dynamic environment system of the power distribution room (or transformer substation) or the DTU and upload its own data to the back-end management system; IoT-enabled smart miniature circuit breakers are used to directly control the start and stop of small water pumps without the need for additional contactor control circuits.

[0017] In a specific embodiment of this utility model, the IoT intelligent miniature circuit breaker has overload and short-circuit protection functions. Its measurement functions include real-time monitoring of parameters such as voltage, current, power, and leakage current. It also features early warning functions supporting abnormal current, voltage, power, and leakage current warnings. The networking function supports 485 communication, Bluetooth, wireless, or Wi-Fi modes, allowing seamless connection with the power distribution room's environmental monitoring system or DTU. Manual / automatic operation is supported: local operation via the circuit breaker handle and remote control via the master station. Fire alarm linkage functions allow for rapid power cut-off in emergencies. The backend management system can also receive real-time data on voltage, current, and equipment status uploaded by the IoT intelligent miniature circuit breaker, remotely control the water pump's start and stop, and provide real-time feedback on the operation results. The small water pump is directly controlled by the IoT intelligent miniature circuit breaker, eliminating the need for traditional contactors or relay circuits. During the rainy season or heavy rain, the system automatically or remotely starts the water pump for drainage. The IoT-enabled smart miniature circuit breaker monitors the water pump's operating status in real time, ensuring timely drainage and traceable faults. By connecting the IoT-enabled smart miniature circuit breaker to the main circuit of the water pump, traditional contactors and auxiliary control circuits are eliminated. It connects to the dynamic environmental monitoring system of the power distribution room (or transformer substation) via RS-485 communication or a wireless network. Used in the automatic drainage system of a smart power distribution room (or smart transformer substation), the IoT-enabled smart miniature circuit breaker monitors the power supply voltage and load current through its own measurement functions. When the voltage disappears, it automatically reports an AC power failure signal. When the master station issues a start command, the miniature circuit breaker closes, only resuming operation after detecting normal load current. The system reports the pump start signal; if the miniature circuit breaker closes but no load current is detected or the miniature circuit breaker does not close after the master station issues a start command, it reports a pump start failure signal; if the miniature circuit breaker opens and there is no load current after the master station issues a stop command, it reports a pump stop signal; if the miniature circuit breaker does not open and there is load current after the master station issues a stop command, it reports a pump stop failure signal; if the miniature circuit breaker opens but there is still load current, it reports a fault signal. The data uploaded to the backend by the IoT smart miniature circuit breaker can more accurately determine the equipment operating status and improve the intelligence level of the power distribution room (or transformer substation).

[0018] Please refer to the details. Figures 1-2 The IoT-enabled smart miniature circuit breaker can perform opening and closing operations using its own built-in operating handle. When operating remotely, it can receive remote control commands from the master station to start and stop the water pump.

[0019] In this embodiment: After communicating with the power distribution room (or transformer substation) environmental control system or DTU, the IoT smart miniature circuit breaker uploads its own data to the backend. During local operation, the IoT smart circuit breaker is used to close and open the circuit breaker via its own operating handle. During remote operation, the master station directly issues remote control commands to the IoT smart miniature circuit breaker to start and stop the water pump. This provides both local and remote control modes, improving operational flexibility, eliminating traditional relay control circuits, reducing wiring complexity, and lowering the failure rate.

[0020] Please refer to the details. Figures 1-2 When the power supply voltage disappears, the IoT smart miniature circuit breaker can automatically report an AC power failure signal; when a normal load current is detected, it reports a water pump start signal; if no load current is detected, it reports a water pump start failure signal.

[0021] In this embodiment, the problem of "relay engaged but water pump not running" in traditional control methods is avoided, ensuring accurate status feedback, real-time monitoring of power status, and preventing maintenance delays caused by circuit breaker misjudgments.

[0022] Please refer to the details. Figures 1-2 The system also includes a fault detection mechanism. When the miniature circuit breaker trips but there is still load current, the system can automatically report a fault signal.

[0023] In this embodiment: it can quickly identify abnormal operation of water pumps, avoid mechanical jamming or electrical faults, prevent equipment damage or safety hazards, improve fault diagnosis efficiency, and reduce manual troubleshooting time.

[0024] Please refer to the details. Figures 1-2 The IoT-enabled smart miniature circuit breaker has an electrical life of 6,000 cycles and is suitable for the infrequent start-stop needs of water pumps, eliminating the need for additional equipment to extend its service life.

[0025] In this embodiment, the water sump in the power distribution room (or transformer substation) will not accumulate water under normal circumstances. Only when there is heavy rain and poor drainage during the rainy season will it be necessary to start the water pump for drainage. Therefore, the 6,000-cycle electrical life of the IoT smart miniature circuit breaker itself is sufficient to meet the normal start-stop operation of the water pump, and there is no need to design an additional contactor to control the water pump.

[0026] Please refer to the details. Figures 1-2 The system simplifies the design of the secondary control loop. It only requires a communication line to be connected to the host computer to realize manual and remote control functions, thereby reducing the complexity and maintenance cost of the system.

[0027] In this embodiment, the intelligent miniature circuit breaker eliminates the need for complex secondary control circuits. Simply connecting the communication line to the host computer enables manual and remote control of the water pump. The system eliminates the traditional secondary control circuit; only the communication line (such as 485 or Wi-Fi) of the IoT intelligent miniature circuit breaker needs to be connected to the host computer to achieve manual and remote control functions. This significantly reduces wiring complexity and the number of components, lowers the risk of line faults, reduces subsequent maintenance costs, and improves system reliability and intelligence.

[0028] The working principle and usage process of this utility model are as follows: The IoT smart miniature circuit breaker is connected to the main circuit of the water pump, eliminating the traditional contactor and auxiliary control circuit. It is connected to the dynamic environmental system of the power distribution room via 485 communication or wireless network. Voltage and current warning thresholds are set, and the master station communication protocol is configured to ensure real-time data upload. The master station periodically polls the status of the miniature circuit breaker. During local operation, the water pump is directly controlled through the circuit breaker handle, and the status is synchronously uploaded to the background. After the master station issues a closing command, the miniature circuit breaker executes the action and feeds back the actual load current, avoiding the problem of "false start".

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
