Description

Technical Field

[0001] This invention relates to the field of industrial automation monitoring technology, and in particular to a base point power monitoring and signal conversion and transmission method. Background Technology

[0002] With the continuous operation of the Jiangsu electricity spot market and the increasing intensity of the assessment of the "two detailed rules" (grid connection operation management rules and ancillary service management rules), generating units are facing higher requirements for the accuracy and response speed of load regulation. As the core command parameter of automatic generation control (AGC), the real-time monitoring and reliable transmission of base point power directly determine whether the generating unit can respond to dispatch commands quickly and accurately, thus affecting the settlement revenue and assessment results of power generation companies in the spot market.

[0003] Currently, in the centralized control operation scenarios of power generation in Jiangsu Province, the methods for monitoring base point power are relatively outdated. The mainstream approach still relies on indirect visualization methods such as screen sharing, camera projection, or remote desktop transmission. These methods not only have significant visual delays but are also highly susceptible to factors such as network jitter and image compression. This prevents centralized control operators from grasping the real load command changes in a timely manner, severely restricting the timeliness and accuracy of load adjustments and increasing the risk of being assessed by the power grid's "two detailed rules".

[0004] In the few existing solutions that combine software and hardware, common problems include poor system compatibility, simplistic data processing logic, a lack of intelligent mapping mechanisms, and a lack of link status self-checking and fault handling mechanisms. Existing solutions are mostly based on dedicated industrial control systems or specific brand hardware, resulting in excessively high software-hardware coupling and an inability to flexibly adapt to general industrial-grade equipment, such as plug-and-play hardware like USB-to-485 serial communication modules and 485-to-4-20mA analog converters. This makes on-site modifications difficult and hardware procurement costs high, hindering low-cost deployment in existing units. Most existing solutions only achieve data pass-through or simple forwarding, without refining the linear mapping relationship between power and current. Especially in the Jiangsu power grid's common scenario of "load 0 corresponding to 4mA, load 630 corresponding to 20mA," existing solutions cannot flexibly configure the range through software, making it difficult to meet the precise conversion requirements of base point power signals for different units and operating conditions. Current technologies generally neglect health management of communication links. When USB-to-485 modules, analog-to-digital converters, or physical lines malfunction, the system cannot proactively detect and alert to the fault, causing the analog signals received by the distributed control system (DCS) to become stuck or distorted. This situation can easily lead to misjudgments by operators, incorrect execution of dispatching instructions, and in severe cases, even cause unit load fluctuations, affecting the stable operation of the power grid.

[0005] In summary, existing baseline power monitoring solutions have significant shortcomings in terms of real-time performance, compatibility, mapping accuracy, and fault self-healing capabilities, making them unsuitable for the high standards of load response required in the Jiangsu electricity spot market environment. Therefore, there is an urgent need for a baseline power monitoring and signal conversion transmission method based on low-cost, general-purpose hardware, supporting software-defined range configuration, and possessing a link self-checking mechanism, to meet the personalized, precise, and highly reliable requirements of baseline power monitoring at power generation sites. Summary of the Invention

[0006] The main objective of this invention is to provide a method for monitoring base point power and converting and transmitting signals.

[0007] Another object of the present invention is to provide a base point power monitoring and signal conversion transmission device.

[0008] The third objective of this invention is to provide a computer device.

[0009] A fourth objective of this invention is to provide a non-transitory computer-readable storage medium.

[0010] To achieve the above objectives, a first aspect of the present invention provides a base point power monitoring and signal conversion transmission method, comprising:

[0011] Raw baseline power data is collected from the data source at preset time intervals, and the raw baseline power data is processed to obtain baseline power data through format standardization. Based on the preset linear correspondence between the power range and the current output range, the base point power data is subjected to amplitude limiting and linear mapping calculation to obtain the target current value. According to the industrial communication protocol, the target current value is encapsulated into a communication command and sent to the signal conversion device through a serial communication module, so that the signal conversion device converts the communication command into a standard analog signal. The system performs a self-check on the communication link status. If a communication abnormality is detected, a fault prompt is output. If the communication is normal, the standard analog signal is transmitted to the monitoring terminal to achieve real-time monitoring of the base point power.

[0012] In one embodiment of the present invention, the step of collecting raw baseline power data from a data source at preset time intervals and performing format standardization processing on the raw baseline power data to obtain baseline power data includes: The program can be configured with a scheduled task to set the data collection interval. The program will perform the first data collection immediately after it starts, and then collect data in a loop at the set interval. The base point power data is read from the power plant control system, instruments or real-time database as the raw base point power data. After collection, the raw base point power data is processed to standardize the format to obtain the base point power data.

[0013] In one embodiment of the present invention, the step of performing amplitude limiting processing and linear mapping calculation on the base point power data based on a preset linear correspondence between the power range and the current output range to obtain the target current value includes: Based on a preset power range, the base point power data is subjected to amplitude limiting processing, and the power values ​​exceeding the range are constrained to the boundary values ​​to obtain the amplitude-limited base point power data. The target current value is obtained by performing linear mapping calculation on the base point power data after the amplitude limiting.

[0014] In one embodiment of the present invention, the step of encapsulating the target current value into a communication command according to an industrial communication protocol and sending it to a signal conversion device via a serial communication module, so that the signal conversion device converts the communication command into a standard analog signal, includes: Initialize the communication parameters of the serial communication module; According to the industrial communication protocol, the target current value is encapsulated into a communication command frame that meets the requirements of the signal conversion device; The serial communication module sends the communication command frame to the signal conversion device, so that the signal conversion device converts the communication command frame into a corresponding standard analog signal.

If a communication abnormality occurs, output a fault prompt message. If communication is normal, the standard analog signal is transmitted to the analog input channel of the monitoring system so that the monitoring system can complete signal acquisition and real-time monitoring. If the signal is successfully transmitted, return to the step of collecting raw base point power data from the data source at preset time intervals, and cyclically execute the acquisition, amplitude limiting, linear mapping calculation and signal transmission process at set intervals.

[0016] To achieve the above objectives, a second aspect of the present invention provides a base point power monitoring and signal conversion transmission device, comprising: The data acquisition module is used to acquire raw base point power data from the data source at preset time intervals, and to perform format standardization processing on the raw base point power data to obtain base point power data.

The communication transmission module is used to encapsulate the target current value into a communication command according to the industrial communication protocol, and send it to the signal conversion device through the serial communication module, so that the signal conversion device converts the communication command into a standard analog signal. The status self-test module is used to perform self-tests on the communication link status. If a communication abnormality is detected, a fault prompt will be output. If the communication is normal, the standard analog signal will be transmitted to the monitoring terminal to achieve real-time monitoring of the base point power.

[0017] To achieve the above objectives, a third aspect of this application provides a computer device, including a processor and a memory; wherein the processor runs a program corresponding to the executable program code by reading executable program code stored in the memory, for implementing a base point power monitoring and signal conversion transmission method as described in the first aspect embodiment.

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] A method for monitoring base point power and converting and transmitting signals according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0024] Example 1 This embodiment provides a method for monitoring base point power and converting and transmitting signals. This method uses a Python program to perform timed acquisition of base point power, linear mapping of power data to a 4-20mA analog signal, and utilizes a USB to RS-485 module and an RS-485 to 4-20mA analog converter to complete signal conversion and transmission. Finally, the standard 4-20mA analog signal is transmitted to the DCS card, with core compatibility meeting the range requirements of 4mA for a load of 0 and 20mA for a load of 630MW. Figure 1 As shown, the method includes the following steps: S1. Collect raw base point power data from the data source at preset time intervals, and perform format standardization processing on the raw base point power data to obtain base point power data.

[0025] Specifically, the system periodically triggers the acquisition logic according to a preset time interval to read raw baseline power data from data sources in the industrial field, including various control systems, measuring instruments, or database systems. Synchronization via a built-in timed task module or an external clock signal ensures the timing accuracy of the acquisition actions. After acquiring the raw baseline power data, the system performs format standardization processing. By uniformly adjusting the data precision, units, or encoding format, it eliminates format differences between different data sources, thereby obtaining standardized baseline power data. This processing method ensures the continuity of data acquisition and the consistency of data format, adapting to various industrial scenarios. For example, in a specific application scenario, the preset time interval can be configured to 5 minutes, the data source can be selected from a power plant PLC or a real-time database, and the format standardization processing may include retaining data values ​​to two decimal places to meet specific accuracy requirements.

[0026] The above technical solution enables automated, timed acquisition of baseline power data, significantly reducing errors and delays caused by manual intervention and improving the real-time performance of the monitoring system. Standardized format processing effectively eliminates format differences between different data sources, improving data compatibility and the accuracy of subsequent processing, ensuring the data input quality of the baseline power monitoring system, and laying a solid foundation for the reliability of the entire signal conversion and transmission process.

[0027] S2, based on the preset linear correspondence between the power range and the current output range, performs amplitude limiting processing and linear mapping calculation on the base point power data to obtain the target current value.

[0028] Specifically, a linear correspondence between the power range and the current output range is pre-configured, where the power range represents the effective operating range of the base point power, and the current output range represents the standard analog quantity range supported by the subsequent signal conversion equipment. To ensure signal safety, the base point power data is first subjected to amplitude limiting, forcibly constraining data exceeding the power range boundary to the boundary value to prevent the final output analog signal from exceeding the hardware's tolerance due to abnormal source data. Subsequently, a linear mapping algorithm is used to convert the amplitude-limited power data into the target current value. As one implementation method, the following linear mapping formula can be used:

[0029] in, The base point power data is after clipping. and These are the minimum and maximum values ​​of the preset power range, respectively. and These are the minimum and maximum values ​​of the preset current output range, respectively. For example, for specific unit load monitoring, the power range can be set to 0 to 630MW, and the current output range to 4 to 20mA. If the collected data is less than 0 or greater than 630MW, it will be used in the calculation as 0 or 630MW respectively.

[0030] This step, through the aforementioned limiting processing and linear mapping calculation, ensures that the output target current value strictly matches the range requirements of the monitoring terminal, effectively avoiding the risk of signal distortion and hardware damage caused by power data fluctuations or anomalies. At the same time, it realizes flexible and accurate conversion of different power ranges to standard analog signals, significantly improving the reliability of signal transmission and system compatibility.

[0031] S3 encapsulates the target current value into a communication command according to the industrial communication protocol and sends it to the signal conversion device through the serial communication module, so that the signal conversion device can convert the communication command into a standard analog signal.

[0032] Specifically, the processing unit encodes the target current value representing the power load into a communication command conforming to the protocol frame format, according to predefined industrial communication protocol rules. The communication command includes at least device addressing information, a function code, and data load, ensuring that the signal conversion device can uniquely identify and accurately parse the target current value. Subsequently, a physical communication link is established through a serial communication module, transmitting the communication command as a serial data stream to the signal conversion device. After receiving and parsing the communication command, the signal conversion device drives its internal digital-to-analog converter circuit to restore the digital command to a continuous standard analog signal output, thereby achieving remote and precise control. As one implementation method, the industrial communication protocol can adopt the Modbus-RTU protocol, the serial communication module can be configured as a USB to 485 module, the signal conversion device can be a 485 to analog converter supporting protocol control, the communication command can be represented as a hexadecimal command frame, and the standard analog signal can be a 4-20mA current signal.

[0033] Through protocol-based encapsulation and serial transmission, the precise conversion of digital control signals into industrial standard analog signals is achieved, improving the anti-interference capability and hardware compatibility of signal transmission, and ensuring the accuracy of signals received by the monitoring terminal and the reliability of system operation.

[0034] S4 performs a self-check on the communication link status. If a communication abnormality is detected, a fault prompt is output. If the communication is normal, the standard analog signal is transmitted to the monitoring terminal to achieve real-time monitoring of the base point power.

[0035] Specifically, this step dynamically determines whether the communication connection is broken or the device is unresponsive by periodically sending status query commands or continuously detecting the physical link level signal. If a communication anomaly is detected, the system immediately interrupts the current transmission process and generates a fault indication signal to prevent erroneous data from misleading monitoring decisions; if communication is confirmed to be normal, the transmission link remains open, and the standard analog signal is stably transmitted to the monitoring terminal, ensuring that the monitoring terminal can achieve real-time monitoring of the base point power based on accurate analog signals. As one implementation method, the software program detects the serial port connection status and the converter response status. If a communication failure occurs, an error message is output in real time, and the converted 4-20mA standard analog signal is transmitted to the DCS card for acquisition.

[0036] This step introduces a communication link status self-checking mechanism, enabling real-time detection and feedback of transmission faults. This effectively avoids signal distortion or monitoring blind spots caused by communication interruptions, significantly improving the operational reliability and maintenance efficiency of the base point power monitoring system.

[0037] In this embodiment, a dedicated base point power monitoring and signal conversion transmission environment is built based on a Python development environment. The Python runtime platform is a PC pre-installed with Python 3.8, and the pyserial==3.5 and schedule==1.2.0 libraries are installed. The hardware includes a USB-to-485 module supporting RS485 and Modbus-RTU, with a serial port of COM3, a baud rate of 9600, no parity, 1 stop bit, and 8 data bits. It also includes a 485-to-4-20mA analog-to-digital converter with Modbus-RTU address 0x01, a single 4-20mA output with a response time ≤100ms, and a DCS card with 4-20mA analog input and a 0.1mA acquisition accuracy, forming a complete hardware and software implementation foundation.

[0038] Furthermore, such as Figure 2 As shown, the hardware setup follows a clear transmission link logic, sequentially connecting the Python runtime environment (industrial PC / PC), USB to 485 module, 485 to 4-20mA analog converter, and DCS card. Specifically, the USB end of the USB to 485 module is inserted into the industrial PC, and its A / B ends are connected to the corresponding A / B ends of the 485 to 4-20mA converter. The 4-20mA output of the converter is then connected to the analog input channel of the DCS card, ensuring a stable hardware communication link.

[0039] This practical exercise was conducted according to the established procedure. First, the parameters were configured in the Python program, setting the serial port parameters to COM3, 9600 baud rate, acquisition interval to 5 minutes, power range to 0-630MW, current range to 4-20mA, and converter Modbus address to 0x01. Immediately after program startup, the first base point power acquisition was performed, simulating a power value of 315MW and standardizing it to 315.00MW. Subsequently, the linear mapping formula I=(315...) was used... 0) / (630 0)×(20 4) +4 calculates the target current value to be 12.000mA. The program then converts 12.000mA into a hexadecimal instruction frame and sends it to the converter via a USB-to-485 module. The converter responds normally and converts the 485 bus signal into a standard 12.000mA analog signal, outputting it to the DCS card. The DCS card successfully acquires the current signal and interprets it as 315MW, completing one full monitoring cycle. Subsequent programs will automatically repeat all the above operations at 5-minute intervals.

[0040] Ultimately, in this embodiment, when the base point power varies within the range of 0-630MW, the converter output current strictly follows a linear mapping relationship. It accurately outputs 4.000mA at 0 MW load and stably outputs 20.000mA at 630MW load. The error of the DCS card's acquired signal is ≤0.1mA, fully meeting the on-site accuracy requirements. The system operated continuously for 72 hours without any communication failures, and the error of timed acquisition was ≤1 second, achieving accurate, reliable, and real-time monitoring of the base point power. Furthermore, this solution is developed based on a Python open-source library, eliminating the need for dedicated industrial control software and significantly reducing system development and deployment costs. Acquisition intervals, power ranges, and serial port parameters can all be flexibly modified through code, adapting to the personalized needs of different power sites. It can also directly adapt to universal USB-to-485 modules and 485-to-4-20mA analog converters, requiring no customized hardware and directly connecting to existing DCS cards in power plants, simplifying on-site deployment and debugging. In addition, the automatic data acquisition mode with a 5-minute time interval requires no manual intervention after the program starts, and it cyclically executes the entire process of data acquisition, conversion and transmission, which effectively improves the automation level of real-time monitoring of base point power and greatly reduces the workload of on-site maintenance personnel.

[0041] Example 2 This invention also provides a base point power monitoring and signal conversion and transmission device, such as... Figure 3 As shown, the device 10 includes: The data acquisition module 100 is used to acquire raw baseline power data from the data source at preset time intervals, and to perform format standardization processing on the raw baseline power data to obtain baseline power data.

[0042] The signal conversion module 200 is used to perform amplitude limiting and linear mapping calculation on the base point power data based on the preset linear correspondence between the power range and the current output range to obtain the target current value.

[0043] The communication transmission module 300 is used to encapsulate the target current value into a communication command according to the industrial communication protocol and send it to the signal conversion device through the serial communication module, so that the signal conversion device can convert the communication command into a standard analog signal.

[0044] The status self-test module 400 is used to perform self-tests on the status of the communication link. If a communication abnormality is detected, a fault prompt will be output. If the communication is normal, a standard analog signal will be transmitted to the monitoring terminal to achieve real-time monitoring of the base point power.
