Description

Technical Field

[0001] This application relates to the field of power monitoring technology, and in particular to methods, devices, equipment, storage media and computer program products for power consumption monitoring. Background Technology

[0002] The 400V power supply system serves as the core power supply circuit for auxiliary equipment in hydropower stations (such as pumps, fans, and lighting systems). Its power data (including voltage, current, active / reactive power, power factor, and cumulative power consumption) is crucial for assessing power supply efficiency, troubleshooting equipment faults, and ensuring reliable power supply. Currently, the monitoring of 400V power supply in hydropower stations generally adopts a "conventional electricity meter + on-site meter reading" model. Specifically, the voltage signal from the 400V incoming switch is stepped down by a voltage transformer (PT), and the current signal is stepped down by a current transformer (CT) before being connected to the electricity meter for measurement. Operating personnel need to periodically visit the site to record the meter readings. While existing low-voltage power distribution monitoring technologies involve the application of intelligent acquisition modules, they are mostly designed for general industrial scenarios and are not adapted to the characteristics of 400V power supply systems in hydropower stations. The most obvious drawback of this existing technology is the poor timeliness of data acquisition. The on-site meter reading mode cannot achieve real-time collection of electricity data. When the plant power system experiences problems such as overload or voltage abnormality, the operators find it difficult to detect them in time, which can easily delay the opportunity to deal with the fault. Even existing technologies involving intelligent acquisition modules are not adapted to the hydropower station scenario and cannot meet the core requirement of 400V plant power system for real-time data.

[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The main solution of this application embodiment is: the power consumption monitoring method is applied to a power consumption monitoring system, which includes a power consumption acquisition module, a touch screen module, and a target monitoring system. The method includes: acquiring power consumption data of a target plant power system through the power consumption acquisition module; performing parameter calculations on the power consumption data using a built-in algorithm to obtain derived parameters of the target plant power system; uploading the derived parameters to the touch screen module; and uploading the derived parameters to the target monitoring system through the touch screen module for real-time monitoring.

[0023] In this embodiment, for ease of description, the following description uses the power consumption monitoring device as the execution subject.

[0024] The 400V power supply system serves as the core power supply circuit for auxiliary equipment in hydropower stations (such as pumps, fans, and lighting systems). Its power data (including voltage, current, active / reactive power, power factor, and cumulative power consumption) is crucial for assessing power supply efficiency, troubleshooting equipment faults, and ensuring reliable power supply. Currently, the monitoring of 400V power supply in hydropower stations generally adopts a "conventional electricity meter + on-site meter reading" model. Specifically, the voltage signal from the 400V incoming switch is stepped down by a voltage transformer (PT), and the current signal is stepped down by a current transformer (CT) before being connected to the electricity meter for measurement. Operating personnel need to periodically visit the site to record the meter readings. While existing low-voltage power distribution monitoring technologies involve the application of intelligent acquisition modules, they are mostly designed for general industrial scenarios and are not adapted to the characteristics of 400V power supply systems in hydropower stations. The most obvious drawback of this existing technology is the poor timeliness of data acquisition. The on-site meter reading mode cannot achieve real-time collection of electricity data. When the plant power system experiences problems such as overload or voltage abnormality, the operators find it difficult to detect them in time, which can easily delay the opportunity to deal with the fault. Even existing technologies involving intelligent acquisition modules are not adapted to the hydropower station scenario and cannot meet the core requirement of 400V plant power system for real-time data.

[0025] This application provides a solution that, through the collection and calculation of power consumption data, enables real-time monitoring of power consumption in hydropower plants, thereby improving the efficiency of power consumption monitoring and maintenance in hydropower plants.

[0026] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or power consumption monitoring device capable of performing the above functions. The following description uses a power consumption monitoring device as an example to illustrate this embodiment and the subsequent embodiments.

[0027] Based on this, this application provides a method for monitoring electricity consumption, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the power consumption monitoring method of this application.

[0028] In this embodiment, the power consumption monitoring method is applied to a power consumption monitoring system, which includes a power acquisition module, a touch screen module, and a target monitoring system. The power consumption monitoring method includes steps S11 to S13: Step S11: Collect power consumption data of the target plant's power system through the power acquisition module.

[0029] It should be noted that the power acquisition module is a device with data acquisition capabilities. Its core technologies include direct voltage acquisition, current signal reception, and electromagnetic interference (EMI) suppression. Its function is to directly acquire the raw power consumption signals of the target plant's power system. In one embodiment of this application, an industrial-grade three-phase power acquisition module is selected as the power acquisition module. It has three direct voltage acquisition channels, three current input channels, and an RS485 communication interface. Its technical parameters meet the following requirements: voltage range supports 0-450VAC direct acquisition (adapted to 400V plant power systems, no PT required); current range adapts to 0-5A signals from the secondary side of the CT; measurement accuracy reaches active power level 0.5S and reactive power level 2; it has EMI suppression (EMC level ≥ GB / T 17626.2) and overvoltage protection functions, adapting to the complex electromagnetic environment of hydropower stations; the module's power supply is taken from the direct-acquisition three-phase AC power, and the module also has a built-in 24V power output to power the touchscreen module.

[0030] Additionally, it should be noted that the target plant power system refers to the specific plant power circuit that requires power monitoring (such as the 400V plant power bus system of a hydropower station), which is the object of data collection. Power consumption data is the basic data reflecting the operating status of the plant power system, including voltage and current signals, and is the data source for subsequent parameter calculations.

[0031] Understandably, the purpose of this step is to obtain the raw operating data of the target plant's power system. By using the signal receiving channel of the power acquisition module, the voltage and current physical signals of the power system are directly captured. This provides real and accurate basic data for subsequent calculation of derived parameters, solving the data distortion problem caused by relying on intermediate transmission and transformation equipment in traditional acquisition methods. Direct acquisition ensures the integrity and accuracy of the raw data.

[0032] Specifically, an industrial-grade three-phase power acquisition module is selected, and corresponding voltage and current acquisition channels are configured. Voltage signals can be directly acquired without the need for voltage transformers; the raw three-phase voltage signal is obtained directly. Current signals are connected to the secondary output of a current transformer. The acquisition frequency can be set according to monitoring requirements, such as a high-frequency acquisition of 500ms / time, or adjusted to different frequencies such as 1s / time depending on the system load. A single acquisition module can correspond to a single busbar incoming cabinet, while multiple busbar sections can be configured with multiple acquisition modules. Independent acquisition by multiple modules enables parallel acquisition of data from multiple circuits, improving the overall monitoring coverage.

[0033] For example, in a 400V power supply system of a hydropower station, a three-phase power acquisition module supporting direct voltage acquisition of 0-450VAC is selected. The module is fixed in the incoming cabinet of each 400V busbar. The three-phase voltage signals of A, B, and C of the incoming switch are directly connected to the voltage direct acquisition channel of the module, and the three-phase current signals of 0-5A on the secondary side of the incoming current transformer are connected to the current input channel of the module. The module acquires the above voltage and current data at a frequency of 500ms / time to complete the acquisition of raw power consumption data.

[0034] Step S12: Calculate the parameters of the power consumption data using a built-in algorithm to obtain the derived parameters of the target plant's power system.

[0035] It should be noted that the built-in algorithm is a data processing algorithm integrated into the power acquisition module. Its core technologies include active power calculation algorithms, reactive power calculation algorithms, power factor calculation algorithms, and cumulative power consumption statistics algorithms. Its function is to perform mathematical operations and logical processing on the raw power consumption data. The built-in algorithm adopts a power calculation method based on a sinusoidal steady-state circuit. Active power is calculated by multiplying the effective voltage value, the effective current value, and the cosine of their phase difference. Reactive power is calculated by multiplying the effective voltage value, the effective current value, and the sine of their phase difference. The power factor is the ratio of active power to apparent power. Cumulative power consumption is calculated by integrating active power over time.

[0036] Furthermore, the active power calculation algorithm is an active power quantification algorithm based on sinusoidal steady-state circuit theory. Its core is to calculate the actual power done in the circuit by using the effective values ​​and phase relationships of voltage and current. The formula for calculating active power is:

[0037] Among them, U eff I represents the effective value of each of the three phase voltages (e.g., the sum of the values ​​calculated separately for phases A, B, and C). eff φ is the effective value of the corresponding phase current, φ is the phase difference between the voltage and current of the same phase, and P is the active power in the circuit.

[0038] Reactive power is used to quantify the power exchange between electric and magnetic fields in a circuit. While it doesn't directly perform work, it affects power quality and is an important basis for evaluating system load characteristics. The formula for calculating reactive power is:

[0039] Among them, U eff I represents the effective value of each of the three phase voltages (e.g., the sum of the values ​​calculated separately for phases A, B, and C). eff φ is the effective value of the corresponding phase current, φ is the phase difference between the voltage and current of the same phase, and Q is the reactive power in the circuit.

[0040] The power factor is a core algorithm reflecting electrical energy utilization efficiency. It quantifies the degree of phase coordination between voltage and current by measuring the ratio of active power to apparent power. The formula for calculating the power factor is: in Apparent power refers to the apparent value of the total power in the circuit. P is the active power in the circuit, and cosφ is the power factor.

[0041] Cumulative electricity consumption is a statistical algorithm based on the time integration of active power. It is used to accumulate the total electricity consumption of the plant's power system within a specific time period and is a core basis for energy consumption assessment. The formula for calculating cumulative electricity consumption is:

[0042] Where E is the cumulative electricity consumption during the time period t0~t1, P is the active power, and t is the time.

[0043] Additionally, it should be noted that the derived parameters are key monitoring parameters derived from the original electricity consumption data, including active power, reactive power, power factor, and cumulative electricity consumption. These are core indicators for evaluating the operating efficiency and status of the plant's power system.

[0044] Understandably, the purpose of this step is to transform raw electricity consumption data into core parameters with practical monitoring significance. The principle is to use built-in algorithms to process the collected raw voltage and current data. Based on the mathematical definitions of parameters such as power and power factor in circuit theory, derived parameters are calculated through the phase relationship and amplitude of voltage and current. This transforms the raw signals that cannot directly reflect the system's operating status into key indicators that are easy to analyze and judge, providing data support for subsequent monitoring and decision-making.

[0045] Specifically, a built-in algorithm unit is integrated into the microprocessor of the power acquisition module to perform synchronous calculations on each set of raw data in real time to obtain derived parameters. According to the monitoring accuracy requirements, different accuracy levels of algorithms are selected, such as the 0.5S level active power calculation algorithm, to meet the monitoring needs of different scenarios. Multiple algorithms work together to output multiple derived parameters at the same time, realizing multi-dimensional monitoring.

[0046] For example, the power acquisition module acquires the effective value of the voltage of phase A at a certain moment as 380V and the effective value of the current as 50A, with a phase difference of 30° between the voltage and the current. The built-in algorithm calculates the active power of phase A as approximately 16454W using 380V×50A×cos30°, and the reactive power of phase A as 9500Var using 380V×50A×sin30°. The power factor is calculated to be approximately 0.866 by the ratio of active power to apparent power (380V×50A=19000VA). At the same time, by integrating the active power over time, the total power consumption within a certain period is accumulated, thus completing the calculation of derived parameters.

[0047] Step S13: Upload the derived parameters to the touch screen module, and then upload the derived parameters to the target monitoring system for real-time monitoring via the touch screen module.

[0048] It should be noted that the "touchscreen module" is an industrial-grade embedded device with data receiving, display and forwarding functions. Its core technologies include RS485 communication technology and data display technology. Its function is to receive derived parameters and forward them to the target monitoring system, while providing local display and interaction.

[0049] Additionally, it should be noted that the target monitoring system is a back-end system used for centralized monitoring and management, including devices such as communication gateways and monitoring hosts. Its core technologies include data receiving technology and data storage and analysis technology, and its function is to achieve centralized monitoring, storage, and analysis of derived parameters.

[0050] Understandably, the purpose of this step is to achieve multi-terminal monitoring of derived parameters. The principle is to establish a data transmission channel between the power acquisition module, the touch screen module, and the target monitoring system using a communication link. The calculated derived parameters are then transmitted sequentially to the touch screen module and the target monitoring system. This breaks through the limitations of traditional data being stored in a decentralized manner and difficult to manage centrally, allowing on-site personnel to view data locally via the touch screen, while back-end management personnel can remotely monitor the data through the target monitoring system, thus achieving real-time data sharing and efficient management.

[0051] Specifically, a communication connection is established between the power acquisition module and the touch screen module via an RS485 cable, configuring a unified communication protocol (such as Modbus-RTU protocol) and communication parameters (baud rate, data bits, parity bits, etc.). The touch screen module is connected to the target monitoring system via an RS485 bus to a communication gateway, which then converts the signal into an Ethernet signal for transmission to the monitoring host. Data upload can adopt a real-time transmission mode to ensure the timeliness of derived parameters, or a timed upload mode can be used as needed to reduce communication bandwidth usage. Derived parameters from multiple power acquisition modules can be aggregated by the touch screen module and uploaded to the target monitoring system in a unified manner, realizing centralized transmission and management of multi-loop data.

[0052] This embodiment, through the above-described scheme, firstly, the power acquisition module directly acquires the basic data of the target plant power system, solving the data distortion and delay problems caused by intermediate transmission links in traditional acquisition methods; then, through the built-in algorithm, the raw data is transformed into core parameters with practical monitoring significance, providing a key basis for system operation status assessment; finally, through the touch screen module and the target monitoring system, local and remote data sharing is realized, breaking the limitations of decentralized data management, and the entire process of plant power data acquisition, processing, transmission and monitoring is realized in a closed loop, improving the real-time performance, accuracy and management efficiency of plant power monitoring, and providing basic support for the intelligent operation of the plant power system.

[0053] Based on the above implementation scheme, in one feasible implementation, the electricity consumption data includes three-phase voltage signals and current signals on the secondary side of current transformers, and the step of collecting the electricity consumption data of the target plant's power system through the electricity acquisition module includes S21~S22: Step S21: Directly connect the three-phase voltage signal of the target plant power system to the voltage direct acquisition channel of the power acquisition module.

[0054] It should be noted that the three-phase voltage signal refers to the three-phase AC voltage signal from the 400V plant bus incoming switch. Its voltage range is between 0-450VAC, and it can be directly connected to the voltage direct acquisition channel of the acquisition module without going through PT step-down.

[0055] Additionally, it should be noted that the voltage direct acquisition channel is an interface channel on the power acquisition module specifically designed for directly receiving voltage signals. Its core technology is high-voltage direct acquisition technology, which allows for the direct reception of target voltage signals without the need for intermediate step-down equipment.

[0056] Understandably, this step eliminates the traditional PT transmission stage by directly connecting the three-phase voltage signal to the voltage direct acquisition channel of the acquisition module, reducing equipment costs and transmission errors. Simultaneously, connecting the CT secondary current signal to the current input channel ensures the standardization and consistency of current measurement. This design simplifies the monitoring loop structure and improves the system's reliability and metering accuracy.

[0057] Specifically, select a voltage direct acquisition channel that supports the voltage level of the target plant power system. For example, for a 400V plant power system, select a direct acquisition channel that supports 0-450VAC. When connecting, the voltage signal cables should be connected to the corresponding direct acquisition channel interfaces of the acquisition module according to the phase correspondence of the three phases A, B, and C. Shielded cables can be used for connection to reduce the impact of electromagnetic interference on signal transmission. For multi-section busbar systems, the three-phase voltage signals of each busbar should be connected to the voltage direct acquisition channel of the corresponding acquisition module to achieve independent acquisition of voltage data for multiple busbar sections. After connection, insulation testing is required to ensure that the insulation performance of the connected lines meets safety requirements.

[0058] Step S22: Connect the secondary current signal of the current transformer of the target plant power system to the current input channel of the power acquisition module.

[0059] It should be noted that a current transformer is an electrical device that converts a large current into a small current. Its core technology is electromagnetic induction technology. Its function is to convert the large current signal of the target plant power system into a safe small current signal, which is easy for the acquisition module to receive.

[0060] Additionally, it should be noted that the secondary current signal of the current transformer is a small current signal (usually 0-5A) output from the secondary winding of the current transformer. It is an indirect signal that reflects the actual current magnitude of the system and provides safe and collectable raw data for the calculation of current-related derived parameters.

[0061] Additionally, it should be noted that the current input channel is a dedicated interface channel on the power acquisition module for receiving current signals. It is used to receive the secondary current signal output by the current transformer and convert it into a computable electrical signal.

[0062] Understandably, the purpose of this step is to achieve safe and accurate acquisition of the current signal of the target plant's power system. The principle is to use the electromagnetic induction principle of the current transformer to convert the large current in the system into a small current signal that the acquisition module can withstand. This signal is then received through the current input channel of the acquisition module, avoiding damage to the equipment caused by directly connecting a large current to the acquisition module. This ensures the safety of the acquisition process. At the same time, the precise transformation ratio of the current transformer ensures the accuracy of the current signal acquisition, providing reliable raw data for subsequent calculation of current-related parameters.

[0063] Specifically, during implementation, a current transformer with an appropriate ratio should be selected based on the rated current of the target plant power system to ensure that the secondary output current is within the range of the current input channel of the acquisition module (usually 0-5A). During connection, the A, B, and C phase current signal cables of the current transformer's secondary side should be connected to the corresponding three current input channel interfaces of the acquisition module. The polarity of the current signal must be ensured to avoid phase errors affecting subsequent power calculations. Shielded cables should be used to reduce electromagnetic interference. In multi-busbar systems, the secondary signal of the current transformer corresponding to each busbar segment should be connected to the current input channel of the corresponding acquisition module to achieve independent acquisition of current data from multiple busbar segments. After connection, the circuit continuity must be checked to ensure smooth signal transmission.

[0064] This embodiment employs the above-described scheme, using a step-by-step access method of "directly acquiring three-phase voltage signals - connecting to the secondary side current signal of the current transformer." For voltage signals, direct acquisition technology is used, eliminating the traditional voltage transformer step-down stage, simplifying the acquisition circuit, and reducing hardware costs and data transmission errors. For current signals, the current transformer's current-converting function is utilized to convert large currents into safe small current signals for connection to the acquisition module, ensuring the safety and accuracy of the acquisition process.

[0065] Based on the above implementation scheme, in one feasible implementation, the step of uploading the derived parameters to the touchscreen module includes S31~S32: Step S31: Connect the power acquisition module to the touch screen module via an RS485 communication link, and configure the communication address and communication parameters of the power acquisition module.

[0066] It should be noted that the RS485 communication link is a serial communication physical link based on the RS485 standard. It establishes a physical data transmission channel between the power acquisition module and the touch screen module through differential signal transmission technology, and has the characteristics of strong anti-interference ability and long transmission distance.

[0067] Additionally, it should be noted that the communication address is a unique identifier (usually 1-255) assigned to each power acquisition module. Device address encoding technology enables the touchscreen module to distinguish and identify multiple acquisition modules. Communication parameters are configuration parameters that ensure normal communication, including baud rate, data bits, stop bits, and parity bits. Communication protocol configuration technology ensures that the communication rate and data format between the acquisition module and the touchscreen module are consistent.

[0068] Understandably, the purpose of this step is to establish a stable and identifiable communication connection between the power acquisition module and the touch screen module. First, a physical transmission channel is built through an RS485 communication link. Then, a unique communication address is assigned to each acquisition module to avoid address conflicts when multiple devices communicate. At the same time, unified communication parameters are configured to ensure that the data transmission rate and format of both parties match, providing a reliable communication foundation for the subsequent uploading of derived parameters and realizing orderly communication between multiple acquisition modules and the touch screen module.

[0069] Specifically, shielded twisted-pair cable is selected as the RS485 communication cable. The RS485 interface of the power acquisition module is directly connected to the RS485 interface of the touch screen module to form a point-to-point communication link. If there are multiple acquisition modules, a bus topology is used to connect them to the touch screen module. The communication address is set through the DIP switch of the acquisition module or the software configuration tool to ensure that the address of each module is unique. For example, addresses 1-4 correspond to the acquisition modules of the 4 bus segments. The communication parameter configuration needs to be done in the system settings interface of the touch screen module. The baud rate can be selected as 9600bps, 19200bps, etc., the data bits are set to 8 bits, the stop bits are set to 1 bit, and the parity bit can be selected as no parity, odd parity, or even parity to ensure that the parameters of the acquisition module and the touch screen module are consistent. After configuration, the stability of the link connection can be verified through the communication test function. The RS485 communication cable can be RVSP2×1.0mm² shielded twisted-pair cable.

[0070] Step S32: Based on the communication address and the communication parameters, the derived parameters are uploaded to the touch screen module via the RS485 communication protocol.

[0071] It should be noted that the RS485 communication protocol is a communication protocol based on the RS485 physical layer (such as the Modbus-RTU protocol). It ensures that the touch screen module can correctly receive and parse data by defining the data frame format and the data transmission format derived from the parsing technical specifications.

[0072] Understandably, the purpose of this step is to achieve accurate transmission of derived parameters from the acquisition module to the touchscreen module. The principle is based on the configured communication address and communication parameters. The acquisition module encapsulates the derived parameters into data frames according to the RS485 communication protocol format and transmits them to the touchscreen module through the RS485 communication link. The touchscreen module identifies the data of the corresponding acquisition module according to the communication address, parses the data frames according to the protocol format, and extracts the derived parameters. Its function is to centrally transmit the derived parameters scattered in the acquisition module to the touchscreen module, realize the local display of the derived parameters and subsequent forwarding, and ensure the accuracy and orderliness of data transmission.

[0073] Specifically, the power acquisition module converts derived parameters such as active power and reactive power into binary data format as specified by the RS485 communication protocol (such as Modbus-RTU), and encapsulates them into complete data frames containing communication address, function code, data information, and checksum. Data uploading can be done in real-time mode, where the acquisition module immediately encapsulates the data frame and uploads it after each calculation of derived parameters to ensure data timeliness. Alternatively, a timed uploading mode can be used, uploading data in batches at preset time intervals (such as 1 second / time) to reduce communication overhead. When multiple acquisition modules exist, the touch screen module communicates with each module sequentially according to a preset polling order, receiving the derived parameters uploaded by each module to avoid data conflicts. After receiving the data frame, the touch screen module first verifies the checksum, then parses the data information to restore the specific values ​​of the derived parameters.

[0074] This embodiment, through the above-described scheme, first establishes a stable and identifiable communication connection between the acquisition module and the touchscreen module, resolving address conflicts and parameter mismatches during multi-device communication and ensuring the reliability of the communication foundation. Then, by utilizing the RS485 communication protocol to standardize the data transmission format, it achieves accurate and orderly transmission of derived parameters, avoiding distortion and confusion during data transmission. Overall, it realizes efficient transmission of derived parameters from the acquisition module to the touchscreen module, providing a stable data channel for subsequent local display and remote forwarding by the touchscreen module, improving the reliability, accuracy, and timeliness of data transmission, and supporting the realization of the monitoring system's local interactive functions.

[0075] Based on the above implementation scheme, in one feasible implementation, the step of uploading the derived parameters to the target monitoring system for real-time monitoring via the touchscreen module includes S41~S43: Step S41: Connect the touch screen module to the communication gateway via RS485 bus.

[0076] It should be noted that the RS485 bus is a bus-type communication network based on the RS485 standard. Through bus topology design and differential signal transmission technology, it realizes the centralized connection of multiple touch screen modules and communication gateways, and has the characteristics of strong scalability and long transmission distance.

[0077] Additionally, it should be noted that a communication gateway is a network device that converts different communication protocols or signal types. It connects RS485 bus and Ethernet network through signal conversion and protocol conversion technologies to enable data transmission between the two networks.

[0078] Understandably, the purpose of this step is to establish a centralized communication connection between the touchscreen modules and the communication gateway. The principle is to use the bus topology of the RS485 bus to centrally connect the communication interfaces of multiple touchscreen modules to the RS485 interface of the communication gateway, forming a star or bus communication network. Its function is to realize the centralized aggregation of data from multiple touchscreen modules, provide a physical channel for subsequent signal conversion and remote transmission, improve the uniformity and scalability of multi-module data transmission, and facilitate the access of new touchscreen modules in the later stages of the system.

[0079] Specifically, shielded twisted-pair cable is selected as the RS485 bus cable. Following a bus topology, the RS485 interface of each touchscreen module is sequentially connected to the RS485 interface of the communication gateway, ensuring good grounding of the bus cable's shielding layer to reduce electromagnetic interference. The communication gateway needs to be configured with a sufficient number of RS485 interfaces to meet the access requirements of existing touchscreen modules, while reserving a certain number of interfaces for system expansion. During connection, wiring should be performed according to the communication address sequence of the touchscreen modules to facilitate later maintenance and troubleshooting. After connection is complete, the port detection function of the communication gateway is used to verify the connection status between each touchscreen module and the gateway to ensure normal communication.

[0080] For example, in the background monitoring system of a hydropower station, a communication gateway with 8 RS485 interfaces was selected. RVSP2×1.0mm² shielded twisted-pair cable was used as the RS485 bus cable. The RS485 interfaces of the four touch screen modules were connected to the four RS485 interfaces of the communication gateway in a bus topology. The shielding layer of the bus cable was grounded at both ends, with a grounding resistance ≤4Ω. By checking the port status through the management interface of the communication gateway, the interfaces corresponding to the four touch screen modules all showed normal connection with no communication abnormality prompts, thus completing the connection between the touch screen modules and the communication gateway.

[0081] Step S42: The derived parameters are converted into RS485 signals via the RS485 bus, and the RS485 signals are converted into Ethernet signals via the communication gateway.

[0082] It should be noted that RS485 signals are differential signals transmitted based on the RS485 bus, and the transmission of derived parameters is achieved on the RS485 bus through differential signal encoding technology.

[0083] Additionally, it should be noted that Ethernet signals are digital signals based on Ethernet standards (such as TCP / IP protocol signals), and high-speed data transmission is achieved in Ethernet networks through Ethernet frame format encoding technology.

[0084] Understandably, the purpose of this step is to achieve signal adaptation and transmission of derived parameters from the RS485 bus to the Ethernet network. The derived parameters are transmitted to the communication gateway via the RS485 bus in the form of RS485 differential signals through the touch screen module. After receiving the RS485 signal, the communication gateway first decodes and extracts the derived parameter data, and then encodes it into an Ethernet signal according to the requirements of the Ethernet protocol. The purpose is to overcome the limitations of RS485 bus transmission distance and transmission rate, so that the derived parameters can be transmitted remotely over long distances and at high speeds through the Ethernet network, thus meeting the remote monitoring needs of the target monitoring system.

[0085] Specifically, the touchscreen module encapsulates the derived parameters into RS485 differential signals according to the RS485 communication protocol, and transmits them to the RS485 interface of the communication gateway via the RS485 bus. After receiving the RS485 signal, the signal conversion unit inside the communication gateway decodes the differential signal to restore the original data of the derived parameters. Then, the original data is encoded into Ethernet data frames according to the TCP / IP protocol format and converted into Ethernet signals. During the signal conversion process, the integrity and accuracy of the data must be ensured to avoid data loss or distortion. The converted Ethernet signal is output through the Ethernet interface of the communication gateway, which can support an adaptive transmission rate of 10 / 100Mbps to adapt to different Ethernet network environments.

[0086] Step S43: The Ethernet signal is transmitted to the target monitoring system, which performs real-time monitoring of the power consumption of the target plant's power system. The communication gateway is configured with a data buffer. When a network failure interrupts the transmission, the derived parameters are stored in the data buffer. The derived parameters are transmitted again after the transmission is restored.

[0087] Understandably, the purpose of this step is to achieve remote real-time monitoring of derived parameters and ensure data security. By transmitting the converted Ethernet signal to the target monitoring system, the monitoring system receives the signal, parses out the derived parameters, and displays, stores, and analyzes them in real time. At the same time, the data buffer of the communication gateway temporarily stores the derived parameters in the event of a network failure, and retransmits the data after the network is restored. The purpose is to achieve remote centralized monitoring of the power consumption of the plant's power system, improve the convenience of management, avoid data loss caused by network failures, ensure data integrity, and provide complete data support for subsequent data analysis and fault tracing.

[0088] Specifically, the Ethernet signal is transmitted via network cable to the Ethernet interface of the monitoring host of the target monitoring system. The monitoring host runs data receiving software, parses the Ethernet data frames, extracts derived parameters, and displays parameters such as voltage, current, power, and cumulative power consumption in real time on the monitoring interface. At the same time, the data is stored in the database, supporting historical data query and report export. The data buffer capacity of the communication gateway can be configured according to actual needs, such as supporting the storage of derived parameter data for the past 7 days. When a network transmission interruption is detected, the gateway automatically stores the subsequently generated derived parameters in the buffer. After the network is restored, the gateway automatically detects the transmission link status. After confirming that it is normal, it retransmits the historical data stored in the buffer to the target monitoring system in chronological order to ensure data continuity. The monitoring system can be set up with a data transmission status monitoring function. When the data retransmission is detected to be complete, a prompt message is given.

[0089] For example, the Ethernet signal is transmitted to the monitoring host of the hydropower station's backend monitoring system via a network cable. The host's data receiving software parses parameters such as phase A voltage 380V, active power 16454W, and cumulative electricity consumption 1000kWh, which are displayed in real time on the monitoring interface. At the same time, the data is stored in an SQL Server database, supporting the querying of historical data by time period and the generation of daily reports. The communication gateway is configured with a 10GB data buffer. When the Ethernet network fails and data transmission is interrupted, the gateway automatically stores the derived parameters for the next hour in the buffer. After the network failure is restored after one hour, the gateway detects that the transmission link is normal and retransmits the derived parameters stored in the buffer for the next hour to the monitoring host in chronological order. After the retransmission is completed, the monitoring system prompts that the data has been completely received, realizing remote real-time monitoring and data security.

[0090] This embodiment, through the above-described scheme, first utilizes the RS485 bus to centrally aggregate data from multiple touchscreen modules, laying the foundation for remote transmission; then, a communication gateway completes the conversion of RS485 signals to Ethernet signals, solving the adaptation problem of different network types and improving data transmission rate and distance; finally, a target monitoring system enables remote centralized monitoring and storage of derived parameters, while the data buffer of the communication gateway ensures data integrity in the event of network failure. Overall, it realizes the entire process of remote transmission, centralized monitoring, and data security assurance of plant power data, improving the reliability, convenience, and data integrity of remote monitoring, and providing key technical support for the remote intelligent management of plant power systems.

[0091] Based on the above implementation scheme, in one feasible implementation, the method further includes steps S51-S52: Step S51: The derived parameters are displayed in real time via the touch screen module.

[0092] Understandably, the purpose of this step is to achieve local visualization of derived parameters. The touchscreen module receives derived parameters uploaded by the power acquisition module in real time, and the built-in display driver dynamically refreshes and displays the parameters according to the preset interface layout (such as partitions for phase voltage, total current, power, etc.). This allows on-site maintenance personnel to quickly view the real-time operating status of the plant power system without relying on the backend system, providing intuitive data support for on-site fault diagnosis and equipment inspection, and improving the efficiency of on-site maintenance.

[0093] Specifically, the touchscreen module features a display interface that categorizes and displays derived parameters. For example, the voltage parameter area displays the three-phase voltage values ​​(A, B, and C); the power parameter area displays active power, reactive power, and power factor; and the energy parameter area displays the cumulative energy consumption. The display interface supports various formats, including numerical displays and trend curve displays. Numerical displays intuitively present the current values, while trend curve displays show the parameter change trends over the past hour or 24 hours. The display resolution is set according to specific requirements to ensure clear parameter display. The parameter refresh rate can be set to match the data upload frequency of the acquisition module (e.g., 500ms / time) to achieve real-time synchronous data refresh. The interface switching function is supported, allowing on-site personnel to switch between different display interfaces via touch operation to view detailed parameters.

[0094] Step S52: When any of the derived parameters exceeds a preset parameter threshold, the sound and light alarm device of the touch screen module is triggered, wherein the sound and light alarm device performs graded alarms based on the deviation distance between the derived parameter and the parameter threshold.

[0095] It should be noted that the parameter thresholds are the upper and lower limits of the parameters preset according to the safety operation requirements of the plant power system, which are used to define the safe operating range of the parameters.

[0096] Additionally, it should be noted that the audible and visual alarm device is an alarm system integrated into the touchscreen module, including a buzzer (audible alarm) and LED indicator lights (visual alarm). It uses alarm triggering and hierarchical control technology to provide sound and light alerts for abnormal parameters. Deviation distance refers to the magnitude by which a derived parameter exceeds its threshold value.

[0097] Understandably, the purpose of this step is to promptly alert users to abnormal derived parameters. The principle is that the touchscreen module compares the derived parameters with preset parameter thresholds in real time. When any parameter exceeds the threshold, an alarm level is assigned based on the deviation distance (such as slight deviation or severe deviation), and the corresponding level of audible and visual alarm is triggered. The purpose is to enable on-site personnel to quickly detect parameter abnormalities during equipment operation, take timely fault handling measures, avoid the abnormality from escalating to cause equipment damage or power outages, and improve the safety and reliability of the plant power system.

[0098] Specifically, in the settings interface of the touch screen module, thresholds for various derived parameters are preset according to the system's rated parameters and safe operation requirements. For example, the voltage threshold is set to 360-420V, the current threshold is set to ≤ rated current (e.g., 50A), and the active power threshold is set to ≤ rated power (e.g., 20000W). The alarm levels are divided into two levels: Level 1 alarm (minor deviation): the parameter exceeds the threshold but the deviation distance is ≤10%, triggering the LED indicator to flash (frequency 1 time / second) and the buzzer to sound intermittently (sound for 1 second and stop for 2 seconds); Level 2 alarm (serious deviation): the parameter exceeds the threshold and the deviation distance is >10%, triggering the LED indicator to flash rapidly (frequency 3 times / second) and the buzzer to sound continuously. Custom settings for alarm thresholds and alarm level intensity are supported to meet the alarm needs of different scenarios. After the alarm is triggered, the touch screen interface synchronously displays the abnormal parameter indicator (e.g., red highlighting of abnormal parameters), making it easy for on-site personnel to quickly locate abnormal parameters.

[0099] This embodiment, through the above-described solution, displays derived parameters in real time via a touchscreen module, enabling on-site maintenance personnel to quickly grasp the system's operating status and solving the problem of traditional manual meter reading's inability to obtain data in real time. Furthermore, by using preset parameter thresholds and a tiered alarm mechanism, it can promptly detect parameter anomalies and provide alarm prompts of varying intensities based on the severity of the anomalies. This allows on-site personnel to quickly locate anomalies, assess the urgency, and take appropriate measures, preventing equipment damage or power supply failures caused by the escalation of anomalies. Overall, it improves the convenience, safety, and reliability of on-site maintenance of the plant power system, providing strong support for rapid on-site fault handling.

[0100] Based on the above implementation scheme, in one feasible implementation, the method further includes steps S61-S62: Step S61: The derived parameters are stored in the historical derived parameter library through the touch screen module, wherein the historical derived parameter library adopts a circular storage architecture.

[0101] It should be noted that the historical derived parameter library is a database built into the touch screen module used to store historical derived parameters, retaining historical records of derived parameters to provide data support for subsequent queries and analysis.

[0102] Additionally, it should be noted that circular storage architecture is a storage method that automatically overwrites the oldest stored data when the storage capacity reaches its limit. Through data overwrite management technology, it continuously stores the latest historical data within a limited storage capacity, ensuring the timeliness of the stored data.

[0103] Understandably, the purpose of this step is to achieve local historical storage of derived parameters. After receiving real-time derived parameters through the touch screen module, the parameters are stored in the historical derived parameter library according to a preset storage frequency (such as consistent with the data acquisition frequency or timed storage). When the storage capacity reaches the upper limit, the oldest historical data is automatically overwritten through the circular storage architecture, and historical parameter records within a certain period of time are retained. This solves the problem of no local historical data storage and inability to trace parameter changes in traditional monitoring methods. It provides data basis for on-site personnel to analyze parameter change trends and troubleshoot historical faults. At the same time, the circular storage architecture ensures continuous storage capacity under limited storage resources.

[0104] Specifically, based on the storage capacity of the touchscreen module, the storage duration of the historical parameter database can be set, such as supporting the storage of nearly 30 days of historical data; the storage frequency can be set to real-time storage (storing once every 500ms) or timed storage (such as storing once every minute). Real-time storage can retain more detailed parameter change records, while timed storage can save storage space; the implementation of the circular storage architecture is that when the stored data reaches the upper limit of 30 days, newly generated parameter data automatically overwrites the earliest data stored on day 1, and so on, always maintaining the latest historical data of nearly 30 days; the stored data includes parameter names, values, collection timestamps, and other information, which facilitates the association of time dimensions when querying later; it can support the integrity verification of stored data to ensure that data is not lost or damaged during the storage process.

[0105] For example, a touchscreen module is configured with 8GB of storage capacity, and a historical parameter library is set to store historical data for the past 30 days. The storage frequency is once every minute, and each time it stores parameters such as the voltage, current, active power, reactive power, power factor, and cumulative energy consumption of phases A, B, and C, as well as the corresponding collection timestamp. After the system has run for 30 days, the parameter data generated on the 31st day automatically overwrites the earliest data stored on the 1st day, and the data on the 32nd day overwrites the data on the 2nd day, thus realizing cyclic storage. Through the data integrity verification function, the stored historical data is found to be without loss or error and can be read normally.

[0106] Step S62: Construct a local query interface and query the derived parameters in the historical derived parameter library through the local query interface.

[0107] It should be noted that the local query interface is an interactive interface or operation entry point set on the touch screen module for querying historical derived parameters, providing on-site personnel with a convenient channel for querying historical data.

[0108] Understandably, the purpose of this step is to enable convenient local querying of historical derived parameters. The principle is to build a local query interface that includes query condition input, data retrieval, and result display functions. On-site personnel input the required query conditions through this interface, and the touch screen module retrieves the corresponding historical data from the historical derived parameter library based on the conditions and displays it to the user in an intuitive form. Its function is to allow on-site personnel to quickly query historical parameter data of specific time periods and types without relying on the back-end system. This provides a convenient means for analyzing parameter change trends and tracing parameter status before and after a fault, thereby improving the efficiency of on-site fault diagnosis and data analysis.

[0109] Specifically, the local query interface can be designed as a touch-screen interactive interface, providing multiple query condition input methods, including time range queries (such as selecting start and end dates) and parameter type queries (such as querying voltage parameters, power parameters, or all parameters individually). Query results can support multiple display formats, such as displaying specific values ​​and timestamps in a table format, or displaying parameter changes over time in a trend curve format. It can support query result export functionality, allowing historical data to be exported to Excel or CSV format files via the touchscreen module interface for subsequent offline analysis. The query interface supports fuzzy search functionality, such as entering a general time range or parameter keywords to retrieve relevant data. A paginated display function for query results can be set, making it easier to view large amounts of query data.

[0110] This embodiment, through the above-described scheme, uses a ring storage architecture to locally retain historical parameter data for a certain period of time on the touchscreen module. This solves the problem of historical data relying on backend storage and being untraceable on-site in traditional monitoring methods. At the same time, the ring storage ensures continuous data retention under limited storage resources. Furthermore, by building a convenient local query interface, on-site personnel can quickly retrieve historical data under specific conditions, supporting multiple display formats and data export. This provides rich data support for on-site analysis of parameter change trends and tracing the causes of faults, improving the efficiency of on-site data analysis and fault diagnosis, further enhancing the local interactive function of the touchscreen module, and strengthening the practicality and on-site adaptability of the entire monitoring system.

[0111] For example, to help understand the implementation process of the power consumption monitoring method, please refer to... Figure 2 , Figure 2 An exemplary system architecture diagram is provided for a power consumption monitoring method.

[0112] Specifically, as shown in the figure, the power consumption monitoring system includes a power acquisition module, a touch screen module, and a target monitoring system. First, the three-phase voltage signals (A / B / C) are led out from the 400V bus incoming switch and directly connected to the voltage direct acquisition channel of the intelligent power acquisition module. At the same time, the secondary current signal of the current transformer is connected to its current input channel, realizing the synchronous acquisition of voltage direct acquisition and current signals. The intelligent power acquisition module has a built-in algorithm unit to perform real-time calculation on the acquired raw power consumption data, generating derived parameters including active power, reactive power, power factor, and cumulative power consumption. The acquisition module uploads the derived parameters to the local touch screen via RS485 cable using the Modbus-RTU protocol. The touch screen has a 1024×600 resolution display interface and receives 24V power output from the acquisition module. The touch screen further transmits the data to the RS485 communication gateway of the hydropower station's background monitoring system via an RS485 shielded cable. The gateway converts the RS485 signal into an Ethernet signal (TCP / IP protocol) and transmits it to the monitoring host. The monitoring host completes the data storage, analysis, and real-time monitoring, thus constructing a fully integrated monitoring system from on-site acquisition and local display to remote monitoring.

[0113] For example, to help understand the implementation flow of the power consumption monitoring method obtained by combining this embodiment with the above embodiment one, please refer to... Figure 3 , Figure 3 A simplified flowchart of a power consumption monitoring method is provided, specifically: First, using a 400V bus as the power supply head, the intelligent power acquisition module directly collects three-phase voltage signals (without voltage transformers) and secondary current signals from current transformers (CT-2 level accuracy) to complete the acquisition of raw power consumption data. The acquisition module's built-in algorithm unit performs real-time calculations on the raw data, generating derived parameters including active power, reactive power, power factor, and cumulative power consumption, ensuring calculation accuracy and real-time performance. The power acquisition module transmits the derived parameters to a local touchscreen module via the RS485 communication protocol. The touchscreen has real-time data display capabilities, dynamically refreshing parameters such as voltage, current, and power, and supports historical data caching and local query export. It also integrates an audible and visual alarm device, which provides graded alarms based on the degree of deviation when parameters exceed limits. The touchscreen further aggregates and uploads the data to the communication gateway via the RS485 bus, converting it into an Ethernet signal before transmitting it to the background monitoring system. The background system enables centralized monitoring of data from multiple bus segments, supporting real-time data display, historical curve plotting, cumulative power consumption statistics, and remote alarm response, forming an integrated monitoring closed loop from data acquisition and local interaction to remote monitoring, comprehensively improving the real-time performance, reliability, and intelligence level of the plant power system monitoring.

The data monitoring module 403 is used to upload the derived parameters to the touch screen module, and then upload the derived parameters to the target monitoring system for real-time monitoring via the touch screen module.
