Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project control, and in particular to an on-site error prevention software system applied to remote control of a sluice pump station. Background Art

[0002] The anti-error system in the remote control of the sluice pump station is a comprehensive system that ensures accurate and safe remote operation of the sluice pump station. It uses identity authentication and permission management mechanisms to ensure that only authorized personnel can perform corresponding operations. It uses real-time monitoring and data acquisition technology to constantly monitor the operating status of equipment and environmental parameters, providing an accurate basis for operation. With the help of the operation process verification function, the legitimacy of operation instructions is verified according to preset logical rules to prevent the execution of non-compliant instructions. A multiple confirmation mechanism is set up to conduct secondary confirmation of key operations to avoid incorrect operations. It also has a log audit and traceability function to record all operation behaviors for subsequent inquiries and accountability tracking, thereby comprehensively reducing the risk of incorrect operations during remote control and ensuring the safe and stable operation of the sluice pump station.

[0003] However, the existing on-site error prevention software system used in the remote control of sluice pumping stations still has the following problems:

[0004] 1. Remote operation is prone to malfunction due to network delays, command errors or misjudgment of equipment status. When delays occur, the commands issued by the remote control center cannot be transmitted to the local equipment in a timely and accurate manner. The control commands may be executed with a lag, causing the equipment response to be out of line with actual needs. In addition, the gate opening sensor is aged or damaged, and the opening data fed back to the remote control center does not match the actual opening, causing the remote control center to issue erroneous commands based on incorrect equipment status information. For example, it may mistakenly believe that the gate is completely closed and issue an opening command, causing equipment conflicts and safety accidents.

[0005] 2. Conflicts between local and remote control permissions. Local and remote control permissions lack clear and reasonable demarcation and an effective coordination mechanism. When remote control is in progress, on-site personnel not managing the equipment may mistakenly press the local control button due to unawareness that the equipment is under remote control, resulting in confusion in the equipment's control instructions and malfunctions.

[0006] 3. Traditional error prevention systems primarily rely on hardware interlocks, designed based on fixed logic and parameters, lacking the ability to sense and adapt to dynamic water level changes in real time. During sudden water level changes, such as during flood season, hardware interlocks cannot quickly respond to sharp rises or falls in the water level, preventing them from adjusting gate openings and pump operating conditions in a timely manner. For example, if the water level rises rapidly above the warning level, the hardware interlocks may continue to operate according to a pre-set fixed program, failing to increase the gate opening to release floodwater in a timely manner. This can cause the water level to continue to rise, inundating surrounding areas. Summary of the Invention

[0007] The purpose of the present invention is to provide a technical solution to solve the problems in the prior art raised in the above background technology.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0013] The anti-error decision-making unit includes a real-time status monitoring module, an instruction pre-calculation module and a self-locking feedback module. The anti-error decision-making unit uses the real-time status monitoring module, the preset water level warning value, the instruction pre-calculation module and the self-locking feedback module to monitor the operating status of the gate pump station in real time and make intelligent decisions to cope with dynamic changes such as sudden changes in water levels.

[0014] Preferably, the dual channel includes optical fiber and 4G+LoRa, the optical fiber is a common channel between the remote control center and the local anti-error host, and the 4G+LoRa is a backup channel between the remote control center and the local anti-error host.

[0015] Preferably, the real-time status dual verification unit includes a hardware security inspection module, a software security inspection module and a network security inspection module. The hardware security inspection module receives the feedback signal of the monitoring module to provide a real-time basis for decision-making for the local anti-error host. The software security inspection module calculates the theoretical opening of the gate based on the fluid mechanics model and combines real-time water level, flow and other data. The network security inspection module sets a heartbeat packet mechanism and sends a heartbeat packet every 200ms. The local anti-error host judges the network delay by monitoring the return time of the heartbeat packet.

[0016] Preferably, the space lock module includes a physical key switch arranged on the local anti-error host, and the switch includes a remote control gear and a local control gear. The local anti-error host selects remote control center control or local control by switching the remote control gear and the local control gear. The cabinet of the local anti-error host is equipped with an RFID personnel identification system. Authorized staff can open the cabinet of the local anti-error host to switch the remote control gear and the local control gear only after confirming their identity information through the RFID personnel identification system.

[0017] Preferably, the time lock module includes a timer. After the local anti-error host receives the remote control instruction issued by the remote control center, the control is delayed by 30 seconds through the timer countdown. If the staff is identified by the RFID personnel identification system or the physical key switch is rotated to the local control gear within the countdown of 30 seconds, the remote control instruction is immediately interrupted, so that the local control can intervene in the remote control in a timely manner.

[0018] Preferably, the real-time status monitoring module collects the water level and gate opening status data of the gate pump station in real time through the monitoring module, and the error prevention decision unit sets the water level warning value according to the design requirements and actual operation conditions of the gate pump station;

[0019] After receiving the remote control command, the command pre-calculation module simulates the result of executing the command based on the data collected by the real-time status monitoring module, and determines whether the water level will exceed the warning level in combination with the water level warning value, and sends an alarm message to the remote control center through dual-channel communication;

[0020] The self-locking feedback module monitors the operating status of the equipment through the real-time status monitoring module and the monitoring module, and controls the action of the gate pump station actuator according to the equipment status after receiving the control instruction.

[0021] Preferably, the monitoring module includes a water level meter, a gate opening sensor, a temperature sensor and a pressure sensor. The water level meter is used to collect the water level of the gate pump station, the gate opening sensor is used to detect the size of the gate opening, the temperature sensor is used to monitor the temperature of the motor and the control cabinet, and the pressure sensor is used to monitor the water pressure in the pipeline or the water pressure borne by the gate to determine whether the design load is exceeded.

[0022] Preferably, the gate pump station actuator includes a gate drive motor and a water pump, and the local anti-error host controls the start and stop of the gate drive motor and the water pump through a self-locking feedback module.

[0024] Preferably, the monitoring module is installed in connection with the input interface of the local anti-error host through a signal line. The monitoring module converts the collected analog signal into a digital signal and transmits it to the local anti-error host, so that the real-time status monitoring module and hardware security inspection module of the local anti-error host can receive feedback signals to determine the status of the gate pump station equipment.

[0025] Technical effects and advantages of the present invention: The on-site error prevention software system for remote control of a sluice pump station proposed by the present invention has the following advantages over the prior art:

[0026] 1. The present invention adopts a dual-channel communication architecture, with high-speed and stable optical fiber transmission as the common channel and 4G+LoRa as the backup channel. Automatic switching ensures communication continuity and effectively reduces the command lag problem caused by network delay. The real-time status dual verification unit performs security checks from three aspects: hardware, software, and network. The hardware security module obtains the real-time physical status of the equipment. The software security module calculates the theoretical opening based on the fluid mechanics model and compares it with the actual opening. The network security module uses the heartbeat packet mechanism to monitor network delays. When the threshold is exceeded, local control is automatically switched to ensure real-time synchronization of remote commands and local status in all aspects, greatly improving the reliability of remote operations and avoiding malfunctions, equipment conflicts, and safety accidents caused by various factors.

[0027] 2. The dynamic permission interlocking unit of the present invention is dynamically managed through the space lock and time lock modules. The physical key switch and RFID personnel identification system of the space lock module clearly define the remote and local control gears, preventing unauthorized personnel from misoperating and improper switching from the perspective of space and personnel permissions. The time lock module is set with a 30-second delay control. Local personnel can intervene in remote commands within the countdown to achieve timely local control, optimize permission management, avoid confusion and malfunction of device control instructions caused by permission conflicts, and improve system security and flexibility.

[0028] 3. The real-time status monitoring module of the anti-error decision unit in the present invention collects data through a variety of sensors to provide a basis for intelligent decision-making. After receiving the remote command, the instruction pre-calculation module combines the real-time data and the water level warning value to simulate the execution result, intercepts the command and issues an alarm in case of abnormality, and the self-locking feedback module monitors the equipment status in real time. When the status conflicts with the command, the equipment is locked and an alarm is issued, and the action of the actuator is controlled at the same time. These measures enable the system to adjust the gate opening and the operating status of the water pump in time according to the sudden change of water level, improve the safety and stability of the gate pump station under complex working conditions, and effectively avoid disasters such as floods caused by the inability to respond to water level changes in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a system block diagram of an on-site error prevention software system used in remote control of a sluice pump station according to the present invention;

[0030] Figure 2 This is a system block diagram of the local anti-error host of the present invention. DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0032] The invention provides Figures 1 to 2 As shown, a local error prevention software system used in remote control of a gate pump station includes a remote control center, which is wirelessly connected to a local error prevention host via dual-channel communication;

[0033] Specifically, such as Figure 1 As shown in the figure, the dual channels include optical fiber and 4G+LoRa. Optical fiber is a common channel between the remote control center and the local anti-error host. Optical fiber has the characteristics of high speed and stability, high data transmission rate and strong anti-interference ability. Therefore, as a common communication channel, it can quickly and accurately transmit large amounts of data between the remote control center and the local anti-error host.

[0034] 4G+LoRa is a backup channel between the remote control center and the local anti-error host. 4G communication has a wide coverage range and can utilize existing mobile communication networks. LoRa has the advantages of low power consumption and long-distance communication. When there is a fiber optic failure, such as line damage or signal interruption, the system will automatically switch to the 4G+LoRa channel to ensure communication continuity.

[0035] The remote control center is connected to the optical fiber communication interface of the local anti-error host through optical fiber, and the 4G+LoRa module is connected to the local anti-error host through the serial port. The remote control center and the local anti-error host transmit data bidirectionally through optical fiber or 4G+LoRa module. The remote control center establishes a connection with the local anti-error host through the optical fiber interface and the serial port of the 4G+LoRa module to realize two-way data transmission, including the remote control center sending control commands to the local anti-error host, and the local anti-error host feeding back device status information to the remote control center. The dual-channel communication architecture improves the reliability and stability of system communication, reduces the risk of system failure due to single communication line failure, and ensures that data between the remote control center and the local anti-error host can be transmitted in real time and accurately, providing a basis for subsequent control and decision-making.

[0036] like Figure 2 As shown in the figure, the local anti-error host includes a real-time status dual verification unit, a dynamic permission interlocking unit, and an anti-error decision unit. The local anti-error host uses the real-time status dual verification unit to double-check the control instructions issued by the remote control center and the local device status to ensure real-time synchronization of remote instructions and local status.

[0037] Specifically, the real-time status dual-verification unit includes a hardware security inspection module, a software security inspection module and a network security inspection module. The hardware security inspection module receives the feedback signal from the monitoring module to provide a real-time basis for decision-making for the local anti-error host. The software security inspection module calculates the theoretical opening of the gate based on the fluid mechanics model and combines real-time water level, flow and other data. The network security inspection module sets a heartbeat packet mechanism and sends a heartbeat packet every 200ms. The local anti-error host judges the network delay by monitoring the return time of the heartbeat packet.

[0038] It is worth mentioning that:

[0039] The hardware security inspection module is connected to the monitoring module and receives signals from various sensors in the monitoring module. These sensors convert the actual physical status of the sluice pump station, such as water level height and gate opening size, into electrical or digital signals. After obtaining these signals, the hardware security inspection module uses them as the basis for the actual status of the local equipment, providing accurate and real-time equipment status information to the local anti-error host. This is the basic data source for subsequent verification and decision-making. By comparing with remote control instructions, it determines whether the equipment status meets the instruction requirements;

[0040] Software security inspection module: Based on a fluid mechanics model, combined with real-time data such as water level and flow, the module applies relevant physical formulas to calculate the theoretical gate opening under current operating conditions. For example, based on the Bernoulli equation and the continuity equation, factors such as water flow velocity and water level difference are considered to determine the theoretical gate opening value. The calculated theoretical opening is then compared with the actual opening obtained by the hardware security inspection module. If the deviation exceeds 5%, an early warning is triggered. This allows for timely detection of equipment operating anomalies and avoids malfunctions due to equipment failure or other reasons.

[0041] Network security module: A heartbeat packet mechanism is implemented. The local anti-error host sends a heartbeat packet to the remote control center every 200ms. The remote control center immediately responds upon receiving the heartbeat packet. The local anti-error host determines network latency by monitoring the time difference between the heartbeat packet's send and return. When the network latency exceeds 500ms, it automatically switches to local control mode. This prevents remote control commands from being inaccurately executed, lost, or erroneous due to network latency, ensuring system security and reliability even in unstable networks.

[0042] like Figure 2 As shown, the dynamic permission interlocking unit includes a space lock module and a time lock module. The dynamic permission interlocking unit dynamically manages the permissions of local and remote control through the space lock module and the time lock module to avoid conflicts between local and remote control permissions.

[0043] The space lock module includes a physical key switch set on the local anti-error host. The switch includes a remote control gear and a local control gear. The local anti-error host selects remote control center control or local control by switching the remote control gear and the local control gear. The cabinet of the local anti-error host is equipped with an RFID personnel identification system. Authorized personnel can only open the cabinet of the local anti-error host to switch the remote control gear and the local control gear after confirming their identity information through the RFID personnel identification system;

[0044] When the switch is in the remote control position, the local control buttons are disabled, preventing unauthorized personnel from operating the switch accidentally. When the switch is in the local control position, remote control is disabled, ensuring the independence of local control. Furthermore, the RFID personnel identification system on the cabinet verifies the identity of the personnel. Only authorized personnel who swipe their cards can open the cabinet and switch positions. This manages local and remote control from the perspective of space and personnel permissions, preventing permission conflicts and misoperations caused by unauthorized personnel accidentally touching the equipment or improperly switching control positions.

[0045] The time lock module includes a timer. After the local anti-error host receives the remote control command from the remote control center, the timer counts down for 30 seconds to delay the control. If the staff is identified by the RFID personnel identification system or the physical key switch is turned to the local control position within 30 seconds, the remote control command will be immediately interrupted, allowing local control to intervene in remote control in a timely manner.

[0046] After receiving the remote control command, the local anti-error host starts a timer for a 30-second countdown. During these 30 seconds, if a staff member swipes a card through the RFID personnel identification system or turns the physical key switch to the local control position, the remote control command will be immediately interrupted, providing a time window for local staff to intervene in the remote control command. Before the remote control command is executed, local staff are allowed to terminate the command in time according to the actual situation on site, realizing timely local intervention in remote control and improving the security and flexibility of the system.

[0047] like Figure 2 As shown in the figure, the error-prevention decision-making unit includes a real-time status monitoring module, an instruction pre-calculation module and a self-locking feedback module. The error-prevention decision-making unit monitors the operating status of the gate pump station in real time and makes intelligent decisions through the real-time status monitoring module, the preset water level warning value, the instruction pre-calculation module and the self-locking feedback module to cope with dynamic changes such as sudden changes in water level.

[0048] Specifically, the real-time status monitoring module collects the water level and gate opening status data of the gate pumping station in real time through the monitoring module. The anti-error decision unit sets the water level warning value according to the design requirements and actual operation conditions of the gate pumping station. After receiving the remote control instruction, the instruction pre-calculation module simulates the result of executing the instruction based on the data collected by the real-time status monitoring module, and judges whether the warning water level will be exceeded in combination with the water level warning value, and sends an alarm message to the remote control center through dual-channel communication. The self-locking feedback module monitors the operating status of the equipment through the real-time status monitoring module and the monitoring module, and controls the action of the gate pumping station actuator according to the equipment status after receiving the control instruction.

[0049] The monitoring module uses various sensors, such as water level gauges and gate opening sensors, to collect real-time status data such as the water level and gate opening of the sluice pump station. These sensors convert the collected analog signals into digital signals and transmit them to the real-time status monitoring module. The module processes and analyzes this data to obtain the real-time operating status of the sluice pump station, providing real-time and accurate equipment operating status information to the error prevention unit. This information forms the basis for subsequent instruction pre-calculations and self-locking feedback. Through continuous monitoring, abnormal conditions in equipment operation can be detected in a timely manner, providing a basis for the system's intelligent decision-making.

[0050] When the command pre-calculation module receives a remote control command, it simulates the consequences of executing the command based on data collected by the real-time status monitoring module, combined with preset water level warning values and relevant mathematical models. For example, it predicts how the downstream water level will change after the gate is opened, determining whether it will exceed the warning level. It then anticipates and assesses the potential consequences before the command is executed. If the pre-calculation results are abnormal, such as water level exceeding the limit, the command is immediately intercepted and an alarm is sent to the remote control center via dual-channel communication. This prevents safety accidents and equipment damage caused by executing erroneous commands, improving system safety and reliability.

[0051] The self-locking feedback module monitors the operating status of the equipment in real time, obtaining the actual status information of the equipment through the real-time status monitoring module and the monitoring module. When receiving a control command, it compares the command requirement with the actual status of the equipment. If a conflict between the equipment status and the command is detected, such as receiving an open command when the gate is stuck, the equipment is immediately locked and an audible and visual alarm is triggered. At the same time, the operation of the gate pump station actuator (such as the gate drive motor and water pump) is controlled according to the equipment status. When an abnormality occurs in the equipment, the equipment can be locked in time to prevent further damage and accidents. The audible and visual alarms remind staff to deal with the fault in a timely manner to ensure the safe and stable operation of the system.

[0052] It is worth mentioning that the monitoring module includes a water level meter, a gate opening sensor, a temperature sensor and a pressure sensor. The water level meter is used to collect the water level of the gate pump station, the gate opening sensor is used to detect the size of the gate opening, the temperature sensor is used to monitor the temperature of the motor and the control cabinet, and the pressure sensor is used to monitor the water pressure in the pipeline or the water pressure borne by the gate to determine whether the design load is exceeded. The gate pump station actuator includes a gate drive motor and a water pump. The local anti-error host controls the start and stop of the gate drive motor and the water pump through the self-locking feedback module.

[0053] The monitoring module is connected to the input interface of the local anti-error host through a signal line. The monitoring module converts the collected analog signal into a digital signal and transmits it to the local anti-error host for the real-time status monitoring module and hardware security inspection module of the local anti-error host to receive feedback signals to determine the status of the gate pump station equipment.

[0054] Various sensors within the monitoring module monitor different physical parameters of the gate pumping station in real time. The water level gauge measures the water level and converts it into an electrical signal; the gate opening sensor detects the actual gate opening and outputs a corresponding signal; the temperature sensor senses temperature changes in the motor and control cabinet and converts temperature values into electrical signals; and the pressure sensor measures the water pressure in the pipeline or on the gate and converts pressure values into electrical signals. These sensors collect analog signals, perform analog-to-digital conversion, and transmit them via signal lines to the input interface of the local anti-error control host. The local anti-error control host's real-time status monitoring module and hardware security module receive these feedback signals, analyze and process them, and determine the status of the gate pumping station equipment. Upon receiving control commands, the self-locking feedback module controls the start and stop of the gate pumping station actuators (gate drive motor and water pump) based on this equipment status information. The monitoring module provides the system with comprehensive and accurate equipment status information, forming the basis for real-time monitoring, verification, and decision-making. By monitoring parameters such as water level, gate opening, temperature, and pressure, abnormal conditions of the equipment can be discovered in a timely manner. The actuator implements the actual operation of the gate pump station according to the control instructions of the local anti-error host, such as opening or closing the gate, starting or stopping the water pump, etc., to ensure the normal operation of the gate pump station.

[0055] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
