Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation electricity technology, specifically to a shared power supply control cabinet for agricultural irrigation and its operation method. Background Technology

[0002] Agricultural irrigation is a core part of agricultural production. Currently, rural irrigation electricity use faces prominent problems such as an imperfect sharing mechanism, low level of intelligent management and control, inadequate safety protection, and poor power supply adaptability.

[0003] Existing irrigation power supply equipment is mostly used independently by a single user, making it impossible for multiple users to share power during peak hours, which can easily lead to overload and waste of resources during peak hours. The equipment relies on manual on-site operation and cannot be remotely controlled or pre-set irrigation tasks, resulting in high costs and low efficiency for manual on-site monitoring. Rural power grids experience large voltage fluctuations and harsh outdoor environments, and existing equipment lacks adequate protection against leakage, overload, waterproofing, and dustproofing. Farmers' unauthorized wiring can easily cause safety accidents such as electric shock and equipment burnout. At the same time, the equipment has a single interface and a narrow voltage compatibility range, making it incompatible with various irrigation equipment such as water pumps of different power, drip irrigation, and sprinkler irrigation, which is insufficient to meet the irrigation power supply needs of scattered farmland.

[0004] To address the aforementioned shortcomings, there is an urgent need for an agricultural irrigation power supply control cabinet that can share power supply, provide intelligent management and control, offer comprehensive safety protection, and has strong power supply adaptability, thereby resolving the problems existing in current technologies. Summary of the Invention

[0005] The purpose of this invention is to provide an agricultural irrigation shared power supply control cabinet and its operation method, which realizes multi-user time-sharing power supply, intelligent and automated management and control throughout the process, multiple safety protections and wide-range power supply adaptation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an agricultural irrigation shared power supply control cabinet, comprising a cabinet body, a shared power supply module, an intelligent control module, a safety protection module, and an adapter power supply module;

[0007] The shared power supply module, intelligent control module, safety protection module, and power adapter module are all integrated inside the cabinet and are electrically connected to each other.

[0008] The shared power supply module is used to realize multi-user time-sharing power supply, power diversion and peak-shifting power scheduling. The intelligent control module is used to realize intelligent management and control of the entire system process and preset irrigation tasks. The safety protection module is used to avoid potential safety hazards in power use and equipment operation and ensure safe power use. The adaptable power supply module is used to adapt to irrigation equipment with different power and complex power grid environment, and solve the defects of existing equipment sharing mode such as imperfection, low level of intelligence, prominent safety hazards and poor power supply adaptability.

[0009] Preferably, the shared power supply module includes a user identification unit, a time-sharing power supply scheduling unit, an electricity metering unit, and a permission hierarchy unit. The user identification unit supports three identification methods: card swiping, QR code scanning, and password, used to verify user permissions and record user electricity consumption information, adapting to farmers' usage habits and preventing illegal electricity use. The time-sharing power supply scheduling unit is used to automatically allocate power supply periods and power output based on user reservation information and irrigation demand priority, realizing electricity diversion and peak-shifting, avoiding overload during peak periods, and ensuring stable power supply. The electricity metering unit is used to accurately measure the electricity consumption and duration of each user, generate electricity consumption details, and synchronize them to the intelligent control module and user terminal. The permission hierarchy unit divides users into ordinary users and administrator users. Ordinary users only have permissions for electricity use, reservation, and query, while administrator users have full permissions such as device parameter setting, user management, fault handling, and data export.

[0010] Preferably, the intelligent control module includes a central controller, a wireless communication unit, a remote monitoring unit, an intelligent linkage unit, and a task preset unit. The central controller is electrically connected to the shared power supply module, the safety protection module, and the adaptive power supply module, respectively, and is used to receive feedback data from each module and send control commands to coordinate the overall operation of the system. The wireless communication unit supports multiple communication modes such as LoRa, NB-IoT, and 4G, enabling bidirectional data transmission with the cloud management platform and user terminals, and adapting to the complex communication environment in rural areas. The remote monitoring unit is used to collect cabinet operating parameters and power consumption parameters in real time, and supports remote start / stop, parameter adjustment, and fault diagnosis. The intelligent linkage unit can be linked with soil moisture sensors and liquid level sensors to automatically adjust power supply parameters according to irrigation needs. The task preset unit allows users to preset irrigation tasks in advance, and can set the irrigation start and end time, power supply power, and irrigation duration. After the preset time is reached, the system automatically starts power supply irrigation without manual intervention.

[0011] Preferably, the safety protection module includes a leakage current protection unit, an overvoltage and undervoltage protection unit, an overload protection unit, a waterproof and dustproof protection unit, and an anti-theft alarm unit. The leakage current protection unit automatically cuts off the power supply and sends an alarm signal within 0.1 seconds when it detects a leakage current exceeding a preset threshold, eliminating the risk of electric shock and addressing the safety risks caused by farmers' unauthorized wiring. The overvoltage and undervoltage protection unit monitors the input voltage in real time; when the voltage exceeds a preset range, it automatically disconnects the power supply and activates a voltage regulation mechanism to address voltage fluctuations in the rural power grid. The overload protection unit monitors the output current to prevent equipment damage and circuit failure due to overload of irrigation equipment. The waterproof and dustproof protection unit adopts a sealed cabinet design with a heat dissipation vent with a waterproof plate on the side and a cable limiting protection structure at the bottom wiring point, achieving a protection level of no less than IP55, suitable for harsh outdoor environments such as high temperatures, extreme cold, sandstorms, and humidity. The anti-theft alarm unit automatically triggers an audible and visual alarm and pushes alarm information to the management terminal when the cabinet is illegally opened, ensuring equipment safety.

[0012] Preferably, the power supply module includes a wide-voltage adaptive unit, a variable frequency speed control unit, and a multi-interface adapter unit. The wide-voltage adaptive unit can adapt to AC input voltages of 180V-450V, effectively addressing the problem of large voltage fluctuations in rural power grids and improving power supply adaptability. The variable frequency speed control unit can automatically adjust the output frequency and voltage according to the power requirements of irrigation equipment and preset irrigation task parameters, achieving on-demand power supply and energy saving. It also has a constant pressure control function to avoid pipeline damage caused by sudden increases in water pressure. The multi-interface adapter unit integrates three-phase and single-phase interfaces, and can simultaneously adapt to water pumps, drip irrigation equipment, and sprinkler irrigation equipment of different power ratings, meeting the diverse irrigation needs of scattered farmland and solving the problem of poor power supply adaptability of existing equipment.

[0013] Preferably, the cloud management platform is used to store user information, electricity consumption data, equipment operation data, and preset irrigation task information. It supports user functions such as power supply reservation, electricity bill inquiry, and recharge payment. At the same time, it can centrally manage multiple control cabinets and generate equipment operation reports and energy consumption analysis reports, which facilitates overall scheduling and operation and maintenance management by managers. The user terminal is a mobile APP, which supports user identity binding, power supply reservation, preset irrigation tasks, real-time viewing of electricity status and bills, and receiving fault and alarm notifications. It is easy to operate and adapts to farmers' usage habits.

[0014] Preferably, the cabinet is made of thickened sheet metal and coated with an anti-corrosion and anti-sun exposure coating to further improve its adaptability to outdoor environments and extend the service life of the equipment. The front of the cabinet is equipped with a protective door, and the lower end of the protective door is equipped with a rotatable baffle to protect the power interface. The baffle is equipped with a limit and fixing structure to keep it in the open state when in use and to close it for protection when not in use, further improving the waterproof, dustproof and safety protection effect and avoiding accidental electric shock.

[0015] Preferably, it also includes a fault self-diagnosis module, which is electrically connected to the intelligent control module. It can detect the operating status of the shared power supply module, the safety protection module, and the adaptive power supply module in real time. When a fault is detected, it automatically locates the fault location, analyzes the cause of the fault, generates a fault diagnosis report and pushes it to the management personnel terminal. At the same time, it activates the backup power supply mechanism to ensure that the power supply is not interrupted during the critical irrigation period and avoids the impact of equipment failure on the irrigation progress.

[0016] Preferably, the shared power supply module supports multiple users to make reservations simultaneously. When a power supply conflict occurs, the time-sharing power supply scheduling unit can automatically sort according to the irrigation area and the urgency of crop water demand, giving priority to ensuring power supply for users with large irrigation areas and urgent crop water demand, further optimizing the sharing mode, improving the user experience, and solving the problems of the existing sharing mode's imperfections.

[0017] 10. Based on an agricultural irrigation shared power supply control cabinet, and further comprising an operation method for the agricultural irrigation shared power supply control cabinet, including the following steps:

[0018] S1. When the equipment starts up, the shared power supply module, intelligent control module, safety protection module and power adapter module integrated inside the cabinet are powered on simultaneously. Each module works together to complete a self-test. After confirming that there are no abnormalities, it enters the standby state. The safety protection module is in a monitoring state throughout the process to avoid potential safety hazards during initial operation.

[0019] S2. Users can initiate irrigation-related operations through the intelligent control module. They can preset irrigation tasks, specify the start and end times of irrigation, and power supply requirements. After receiving the instructions, the intelligent control module sends a scheduling signal to the shared power supply module and an adaptation instruction to the adaptive power supply module. The adaptive power supply module adapts the power supply parameters according to the preset power supply and the connected irrigation equipment.

[0020] S3. The shared power supply module, based on the scheduling instructions of the intelligent control module and the current power consumption situation, realizes power diversion and peak-shifting power scheduling, allocates appropriate power supply periods and power to the current irrigation task, avoids power overload, ensures power supply stability, and records relevant information on current power consumption.

[0021] S4. During irrigation, the intelligent control module realizes intelligent management and control of the entire process, collects the power consumption data of the shared power supply module and the operating parameters of the adapted power supply module in real time, and synchronously feeds them back to the safety protection module. The safety protection module monitors the power consumption status in real time, avoids safety hazards such as leakage and overvoltage in a timely manner, and ensures safe power use.

[0022] S5. After the irrigation task is completed, the intelligent control module sends a power stop command, the shared power supply module stops supplying power, the adapter power supply module resets to standby mode, the safety protection module continuously monitors the status of the equipment after power failure, and the intelligent control module records complete data of this irrigation and power consumption, thus completing one irrigation power supply operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention achieves reasonable layout, diversion and staggered power consumption during peak irrigation periods by integrating a shared power supply module and an intelligent control module inside the cabinet, ensuring the safety of agricultural irrigation power consumption. At the same time, it enables remote intelligent control, avoiding the situation where traditional irrigation methods rely too much on manual labor, resulting in low irrigation efficiency and abnormal voltage fluctuations in the power grid due to the inability to achieve shared power consumption.

[0035] 1. User identification unit: Supports three identification methods: card swiping (RC522 RF card reader module), QR code scanning (GM65 QR code scanner), and password (touch button password input board). Farmers can choose the verification method according to their usage habits. After the system verifies the user's identity, the system will grant the user's electricity access permission and automatically record information such as the user's identity and the start time of electricity use to prevent illegal electricity use and theft.

[0036] 2. Time-sharing power dispatching unit (core chip STM32F103): Receives user reservation information, divides power consumption priority according to irrigation area and crop water demand urgency, and automatically allocates power supply time periods and power to achieve power diversion and peak-shifting power consumption; when multiple user reservations cause power supply conflicts, priority is given to users with large irrigation areas and urgent crop water demand to avoid grid overload during peak power consumption periods and ensure continuous and stable power supply.

[0037] 3. Electricity metering unit (HLW8032 high-precision electricity metering chip): It adopts a high-precision metering chip to accurately measure the electricity consumption, duration of use, and power consumption of each user, generate electricity consumption details in real time, and transmit them synchronously to the intelligent control module and user terminal to provide data support for billing and reconciliation.

[0038] 4. Hierarchical Access Control Unit: Users are divided into regular users and administrator users. Regular users can only perform operations such as electricity usage, reservations, and bill inquiries; administrator users can perform full-function operations such as equipment parameter configuration, user information management, fault diagnosis and handling, and electricity data export, thus achieving hierarchical control.

[0039] The intelligent control module includes a central controller, a wireless communication unit, a remote monitoring unit, an intelligent linkage unit, and a task preset unit.

[0040] 1. Central Controller (STM32F407ZET6): As the core of the system, it is electrically connected to the shared power supply module, the safety protection module, and the adapter power supply module.

It supports managers and users to remotely start and stop the equipment, adjust power supply parameters, and troubleshoot operational faults through the terminal without the need for on-site supervision.

[0043] 4. Intelligent linkage unit: It has reserved sensor interfaces and can be connected to external soil moisture sensors and liquid level sensors to collect farmland soil moisture and water source liquid level data in real time. When the data is lower than the threshold, it automatically triggers power supply for irrigation, realizing on-demand water supply and intelligent water saving.

[0044] 5. Task Preset Unit: Supports users to preset irrigation tasks in advance, and customize the start and end times of irrigation, power supply, and duration. The system will automatically start power supply after the preset time is reached and automatically shut off power after irrigation is completed, with fully automated operation.

[0045] The safety protection module includes a leakage protection unit, an overvoltage and undervoltage protection unit, an overload protection unit, a waterproof and dustproof protection unit, and an anti-theft alarm unit.

[0046] 1. Leakage Protection Unit: The leakage protector monitors the leakage current of the power supply circuit in real time. When the leakage current exceeds the preset safety threshold, it will quickly trip and cut off the power within 0.1 seconds and send a leakage alarm signal to the terminal, completely eliminating the safety hazard of electric shock and solving the safety risks of farmers' unauthorized wiring.

[0047] 2. Overvoltage and undervoltage protection unit: The overvoltage and undervoltage protector continuously monitors the input grid voltage. When the voltage exceeds the safe range of 180V-450V, it immediately disconnects the power supply circuit and starts the voltage regulation mechanism to stabilize the output voltage and cope with the problem of large voltage fluctuations in rural power grids.

[0048] 3. Overload protection unit: The molded case circuit breaker monitors the output current in real time. When the current exceeds the rated power of the irrigation equipment or an overload occurs, it automatically cuts off the power supply to prevent equipment burnout, short circuits and other faults.

[0049] 4. Waterproof and dustproof protection unit: The cabinet adopts a sealed design, with heat dissipation vents with waterproof plates on the side and cable limiting protection structure added at the bottom wiring point. The overall protection level is not lower than IP55, which can adapt to harsh outdoor environments such as high temperature, severe cold, wind and sand, and humidity.

[0050] 5. Anti-theft alarm unit: The cabinet's protective door is equipped with an anti-tamper sensor switch. When the cabinet is illegally pried open, an audible and visual alarm is immediately triggered, and the alarm information is pushed to the administrator's terminal to ensure the safety of equipment and property.

[0051] The power supply module includes a wide voltage adaptive unit, a variable frequency speed control unit, and a multi-interface adapter unit.

[0052] 1. Wide voltage adaptive unit: It can adapt to a wide range of AC input voltage from 180V to 450V, automatically adjust the output voltage, effectively solve the problem of unstable and large voltage fluctuations in rural power grids, and improve power supply compatibility.

[0053] 2. Variable frequency speed control unit: Based on the power requirements of the irrigation equipment and the preset irrigation task parameters, it automatically adjusts the output frequency and voltage to achieve on-demand power supply and energy saving; at the same time, it has a constant pressure control function to stabilize the water supply pressure and avoid pipe rupture caused by a sudden increase in water pressure.

[0054] 3. Multi-interface adapter unit: It integrates a three-phase 380V power supply interface and a single-phase 220V power supply interface, which can simultaneously adapt to different types of irrigation equipment such as high-power water pumps, drip irrigation equipment, and sprinkler irrigation equipment, to meet the power supply needs of scattered farmland and simultaneous irrigation of multiple devices. The time-sharing power supply scheduling unit automatically matches the corresponding interface according to the user's equipment type, realizes the separation of power supply for high-power equipment and low-power equipment, and improves the power supply utilization rate.

[0055] It also includes a fault self-diagnosis module, which is electrically connected to the intelligent control module. It monitors the operating status of the shared power supply module, safety protection module, and adaptive power supply module in real time. When a fault is detected, it automatically locates the fault location, analyzes the fault type, generates a diagnostic report, and pushes it to the administrator terminal. At the same time, it activates the backup power supply mechanism to ensure that the power supply is not interrupted during critical irrigation periods and does not affect agricultural production.

[0056] The cabinet is made of thickened sheet metal with a surface coating that is corrosion-resistant and sun-resistant, enhancing its outdoor durability. A protective door is installed at the front of the cabinet, with a rotatable baffle at the bottom. The baffle has a limit and fixing structure, which can be opened when in use and closed for protection when not in use, further improving the waterproof and dustproof effect and preventing farmers from accidentally touching it and getting an electric shock.

[0057] Along with the user terminal, a cloud management platform is also used;

[0058] The cloud management platform centrally stores user information, electricity consumption data, equipment operation data, and irrigation task data. It supports users to make online power supply appointments, check electricity bills, and pay bills. It also provides administrators with access to equipment operation reports, energy consumption analysis reports, and user information registration forms.

[0059] The user terminal uses a mobile app to support user identity information binding, electricity reservation, irrigation task preset, real-time viewing of electricity status, and receiving fault alarm notifications.

[0060] The cabinet is equipped with multiple independent power supply circuits. Each power supply circuit is equipped with an independent control switch, independent power metering, and independent safety protection. The circuits are electrically isolated from each other and do not interfere with each other. After the user terminal is authenticated, the time-sharing power supply dispatching unit automatically detects the idle circuit and allocates a dedicated power supply circuit to the current user, so as to realize the simultaneous power consumption of multiple users and physical power distribution.

[0061] The system presets a maximum total output power for the control cabinet. The time-sharing power dispatching unit collects the power consumption of each circuit in real time and dynamically monitors the total load. When the total power approaches the maximum limit, new users are prohibited from connecting or the power supply to non-emergency users is automatically reduced to ensure that the power grid and equipment are not overloaded.

[0062] When multiple users apply for power simultaneously, exceeding the power supply capacity of the control cabinet and causing a power supply conflict, the time-sharing power dispatching unit automatically sorts them according to priority level and conflict handling procedure.

[0063] Priority ranking can be determined based on the size of the irrigated area, the urgency of water needs for different crops, and the order in which reservations are made.

[0064] The larger the irrigation area, the higher the priority level; the higher the urgency of crop water demand, the higher the priority; users who have made reservations have priority over users who need immediate use. Ensure the power supply control cabinet can stably transmit and distribute electricity.

[0065] Priority weight = Irrigated area × 0.5 + Water demand urgency × 0.3 + Reservation sequence × 0.2

[0066] The urgency level can be set from 1 to 5, with level 3 as the default; the larger the area and the more urgent the situation, the higher the priority.

[0067] Conflict resolution process

[0068] The system automatically calculates the power priority level and sorts users accordingly; high-priority users are powered immediately; low-priority users are put into a queue and the waiting time is displayed; after the previous user finishes irrigation, the system automatically powers the queued users to ensure smooth system operation.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The adaptive power supply module adapts the power supply parameters according to the preset power supply and the connected irrigation equipment. S3. The shared power supply module, based on the scheduling instructions of the intelligent control module and the current power consumption situation, realizes power diversion and peak-shifting power scheduling, allocates appropriate power supply periods and power to the current irrigation task, avoids power overload, ensures power supply stability, and records relevant information on current power consumption. S4. During irrigation, the intelligent control module realizes intelligent management and control of the entire process, collects the power consumption data of the shared power supply module and the operating parameters of the adapted power supply module in real time, and synchronously feeds them back to the safety protection module. The safety protection module monitors the power consumption status in real time, avoids safety hazards such as leakage and overvoltage in a timely manner, and ensures safe power use. S5. After the irrigation task is completed, the intelligent control module sends a power stop command, the shared power supply module stops supplying power, the adapter power supply module resets to standby mode, the safety protection module continuously monitors the status of the equipment after power failure, and the intelligent control module records complete data of this irrigation and power consumption, thus completing one irrigation power supply operation.
