Abstract
Description
Technical Field
[0001] This invention relates to the field of gas equipment testing technology, specifically to an electrical instrument testing device and its testing method. Background Technology
[0002] Natural gas, as a clean and low-carbon fossil energy source, has a wide range of applications, especially in power generation. However, generating electricity using natural gas is a large-scale and complex project. This often leads to difficulties in inspecting existing gas-fired power generation equipment due to inherent limitations, making it inconvenient for staff to perform checks and operations. Maintenance also requires significant time and manpower to inspect and maintain the various instruments within the equipment. Furthermore, traditional battery capacity testing and incineration require the batteries to be offline, which is not only time-consuming but also disrupts the normal operation of the entire system. Frequently performing battery testing offline also poses a risk to the overall operational safety of the equipment.
[0003] Online monitoring of battery capacity and status has gradually become a reality, and with technological advancements, artificial intelligence (AI) predictive methods are increasingly being incorporated into online monitoring processes. However, for equipment such as gas turbines, direct monitoring and timely maintenance during operation remains challenging. The application of AI is still in its early stages, and the accuracy of monitoring results cannot be directly used as a reliable indicator. Emergency incidents or adjustments during equipment operation still cannot be effectively controlled in a timely manner.
[0004] To ensure the normal operation of equipment such as gas turbines while simultaneously facilitating timely inspection and maintenance, a testing device is needed that can perform real-time online monitoring, effectively handle emergencies, and autonomously adjust. It should also generate valid and reliable reference data for staff to directly consult, significantly improving work efficiency and reducing workload. Summary of the Invention
[0005] Based on the above situation, the main objective of this invention is to provide an electrical instrument testing device and its testing method that enables testing operations to be performed on equipment such as gas engines while they are running, allowing for timely detection of equipment problems and coordinated processing of instrument data and real-time testing data. This facilitates the timely detection of emergencies, protects equipment, reduces the workload of staff, generates valuable testing reports, and meets the needs of personnel.
[0006] The technical solution adopted by this invention to solve its technical problem is as follows: According to a first aspect of the present invention, an electrical instrument testing device is provided, installed in a gas pressure regulating station, including a cloud platform, and further comprising: a main control unit, a communication module, and a wide-temperature power management module. The main control unit connects to the communication unit, the wide-temperature power management module, and the cloud platform. The communication module connects to a gas pressure sensor, a generator controller, and a battery activator. It identifies discrepancies and abnormal data, and generates warning and linkage instructions based on the specific applicable situation, protecting equipment safety and handling problems during equipment operation in a timely, accurate, and efficient manner. The wide-temperature power management module includes an interface expansion module, a gas module, a power generation module, and a battery module. The interface expansion module also receives real-time data from the instruments. The main control unit issues linkage and warning instructions to the wide-temperature power management module, and the gas module, power generation module, and battery module execute the linkage and warning instructions. The warning instructions are also reflected on the instruments through the interface expansion module. Online detection during equipment operation can be achieved without affecting normal equipment operation. The cloud platform is also connected to an encryption module, which connects to external nodes. The main control unit generates timestamped inspection logs, which are then uploaded to the cloud via an encryption module. User terminals can connect to the cloud. The inspection logs also include equipment self-test results and records of abnormal data values. Encrypting the data and inspection logs before uploading them to the cloud facilitates user viewing, as user terminals cannot directly modify the data results. This ensures the authenticity and reliability of the data, reduces the workload of staff checking each device individually, and avoids the safety hazards associated with downtime inspections.
[0007] Furthermore, the main control unit generates linkage and warning commands based on real-time data from the gas pressure sensor, generator set controller, and battery activator, as well as real-time instrument data, and sends them to the wide-temperature power management module. The linkage command is as follows: if the gas pressure drops sharply and the gas module's output decreases accordingly, the generator module's power output will drop to 60%, and the battery module will discharge to replenish 20% of the load. The warning command is as follows: if the gas pressure drops below 0.35 MPa for 500 ms, the instrument will sound an alarm. The main control unit analyzes the received real-time data, identifies equipment problems based on the data, and issues warning or linkage commands according to the equipment conditions to directly and quickly resolve equipment issues.
[0008] Furthermore, the communication module connects to the gas pressure sensor via the TSV protocol, the generator set controller via the CAN bus, and the battery activator via the Modbus protocol. It also features an external interface via fiber optic cable for manually connecting external devices. The communication module supports multiple connection methods, ensuring the accuracy and effectiveness of the collected data, which can be directly used as reference data by staff.
[0009] Furthermore, the wide-temperature power management module is encapsulated by a ceramic substrate and a metal plate, and is disposed in a high-temperature electrical room. The wide-temperature power management module is connected to the gas module, the power generation module, and the battery module through the interface expansion module, and enables the gas module, the power generation module, and the battery module to execute linkage instructions. The wide-temperature management module reflects the warning instruction to the instrument through the interface expansion module, and collects the instrument data through the interface expansion module and uploads it to the main control unit. The encapsulated wide-temperature power management module can adapt to various environmental conditions and has strong practicability. The wide-temperature power management module executes corresponding instructions according to the received instructions for the connected modules, adjusts the equipment to maintain a normal operating state, avoids equipment failures, and avoids situations where the equipment is damaged due to the inability of the staff to operate in time.
[0010] Furthermore, the encryption module connected to the cloud is integrated by several algorithm chips. The encryption module also exchanges data information through an external protocol. The external node is used for the connection of the to-be-developed protocol, which is convenient for enriching the functions of the detection equipment. The encrypted uploaded data cannot be randomly changed at the user end, ensuring the accuracy and authenticity of the data, and providing strong support for the staff to detect the equipment online.
[0011] Furthermore, the interface expansion module also accesses a gas flow meter, a temperature sensor, and a relay. The operation conditions of the equipment after executing the instructions are more accurately reflected through the intervened devices, ensuring the efficient operation of the equipment.
[0012] According to another aspect of the present invention, there is provided a detection method for an electrical instrument and meter detection device, including the following steps: S110. Connect the device and perform self-check. Connect the terminal of the detection device to the gas pressure regulating station and access the power supply. After power-on, detect the connection status of the main control unit, the communication module, the wide-temperature power management module, and each component instrument, and record the initial values; S120. Collect multi-source data simultaneously, record and monitor the data information. In the communication module, collect the data of the gas pressure sensor through the TSV protocol, collect the data of the generator set controller through the CAN bus, collect the data of the battery activator through the Modbus protocol. In the wide-temperature power management module, collect the instrument data through the interface expansion module, and encrypt and upload the collected multi-source data to the main control unit; S130. Generate a report and process it. The main control unit generates a detailed inspection log with a timestamp for the multi-source data, and detects whether there are different data results in the multi-source data. If so, continue to judge which different data result it is, and continue to judge whether to execute the linkage instruction or the warning instruction; if not, save it locally and upload it to the cloud. At the same time, the different data results and the processing information are also included in the inspection log and sent to the cloud; S140. Equipment maintenance. Staff regularly inspect whether each part module is operating normally. The staff remotely view the inspection logs and check whether the instrument data is consistent with the actual device data, and adjust the self-inspection standards according to the actual device operation conditions.
[0013] This method can not only achieve online detection during the operation of the equipment without affecting the normal operation of the equipment. At the same time, it can also find out the difference values and abnormal data based on the detected real-time data results, and generate warning instruction processing situations and linkage instruction processing situations for specific applicable situations according to the analysis, protect the safety of the equipment, and timely, accurately and efficiently handle the problems during the operation of the equipment.
[0014] Further, in step S120, the multi-source data collected by the communication module includes: The gas pressure, temperature and flow information in the gas pressure sensor; The output power, frequency and rotational speed information of the generator set in the generator set controller; The battery pack voltage, current and internal resistance in the battery activation instrument.
[0015] Collect data information in multiple aspects, ensure the effectiveness of the detection and adjustment operations, operate the equipment efficiently, and provide effective data support in multiple aspects for the staff's online detection.
[0016] Further, in step S130, the judgment of which difference data result includes: judging whether to execute the linkage instruction or the warning instruction for the current data difference result; The warning instruction is that the gas pressure is lower than 0.35 Mpa for 500 ms, the air pressure does not continue to drop, there is an instrument warning, and it is recorded; The linkage instruction is that if the gas pressure exceeds the preset value of the warning instruction and continues to drop, then set: when the gas pressure drops suddenly continuously and is accompanied by the gas module, the power generation power of the power generation module is reduced to 60%, and the battery in the battery module discharges to supplement 20% of the load.
[0017] Avoid equipment problems caused by the staff not having time to repair and adjust the equipment in time, and actively repair and maintain the equipment according to the data situation to achieve the sustainable operation of the equipment.
[0018] Further, in step S120, the checked logs are encrypted and uploaded and cannot be changed, and are stored by the cloud, and the user side only views them. This ensures the authenticity and referenceability of the data, provides strong guarantee for the staff's online detection, and reduces the workload of the staff.
[0019] The beneficial effects of the present invention include: Firstly, the main control unit in the electrical instrument testing equipment provided by this invention receives equipment information and instrument dataset information from the communication module and the wide-temperature power management module, enabling online testing during equipment operation without affecting normal operation. Secondly, based on the detected real-time data results, the main control unit identifies discrepancies and abnormal data, and generates warning and linkage instructions for specific applicable situations, protecting equipment safety and handling problems during equipment operation in a timely, accurate, and efficient manner. Thirdly, the main control unit also generates timestamped inspection logs and encrypts the data and logs before uploading them to the cloud for easy viewing by users. Users cannot directly modify the data results, ensuring data authenticity and reference value, reducing the workload of staff checking equipment one by one, avoiding safety hazards caused by shutdown inspections, and promoting stable equipment use.

[0020] Figure 1 This is a schematic diagram of the structure of the electrical instrument and meter testing equipment provided in an embodiment of the present invention; Figure 2 This is a flowchart of the testing method for electrical instrument testing equipment provided in an embodiment of the present invention. Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] Please refer to Figure 1To enable timely detection and handling of equipment such as gas turbines while ensuring normal operation, this application provides an electrical instrument testing device. In daily use, this device is typically located in a gas pressure regulating station. The device includes a cloud platform, a main control unit, a communication module, and a wide-temperature power management module. The main control unit connects the communication unit, the wide-temperature power management module, and the cloud platform. The cloud platform serves as the information storage terminal for the testing device, ensuring the integrity and comprehensiveness of data information and facilitating user access and querying, thus optimizing the practicality of the testing device. The communication module connects to the gas pressure sensor, generator set controller, and battery activator. It receives real-time data from these components and transmits it to the main control unit for processing. The wide-temperature power management module includes an interface expansion module, a gas module, a power generation module, and a battery module. The main control unit issues linkage and warning commands to the wide-temperature power management module, and the interface expansion module also receives real-time data from the instruments. The wide-temperature power management module can adjust the gas module, power generation module, and battery module within the device according to commands. The linkage command refers to the main control unit analyzing the collected detection data and then coordinating the adjustment of the gas module, power generation module, and battery module. The warning command refers to adjusting the gas module only based on the currently detected data and reflecting the warning command on the instrument. Furthermore, the interface expansion module receives instrument data in real time. This serves two purposes: firstly, to monitor changes in instrument data before and after adjustment, as well as the instrument display data during equipment operation; and secondly, to proactively report instrument data to the main control unit.
[0023] To ensure the authenticity and reliability of the test data, an encryption module is set up in the cloud to encrypt the data, making it difficult for users to easily modify the test data. The encryption module also connects to other modifiable protocols, facilitating the handling of emergency matters by users. The main control unit generates timestamped inspection logs and uploads them to the cloud through the encryption module. Users can connect to the cloud, and the inspection logs also include equipment self-test results and records of data anomalies. The main control unit generates timestamped inspection logs that are easy for staff to process, better meeting their needs. This online testing during equipment operation does not affect normal equipment operation, thus truly ensuring the authenticity and reliability of the data. It reduces the workload of staff checking equipment data one by one, avoids the safety hazards of downtime inspection operations, and promotes stable equipment use.
[0024] Specifically, the main control unit generates linkage and warning commands based on real-time data from the gas pressure sensor, generator set controller, and battery activator, as well as real-time instrument data, and sends them to the wide-temperature power management module. The main control unit analyzes the differences in the detected data and issues different commands based on these differences. When the gas pressure remains below 0.35 MPa for 500 ms, the instrument displays an alarm, and a warning command is issued to the wide-temperature power management module for targeted adjustment and alerts. When a sudden drop in gas pressure is detected within the equipment, a linkage command is sent to the wide-temperature power management module. Specifically, if the gas pressure continues to drop sharply and the gas module's output decreases accordingly, the generator module's power output is reduced to 60%, and the battery module discharges to replenish 20% of the load. This coordinates the gas module, generator module, and battery module to protect the equipment and prevent potential safety hazards such as malfunctions.
[0025] In practical applications, wide-temperature power management modules are typically encapsulated using ceramic substrates and metal plates. These encapsulated modules offer a wide temperature range of -40 to 85°C, with a 24V DC input and a 5V / 12V output. This allows them to be installed in high-temperature power rooms or low-temperature voltage regulation stations, facilitating the adjustment of individual modules. The wide-temperature power management module connects to the gas module, generator module, and battery module via an interface expansion module, enabling these modules to execute linkage and warning commands. The wide-temperature management module also relays warning commands to instruments via the interface expansion module and collects instrument data, uploading it to the main control unit. This ensures equipment safety and provides timely, accurate, and efficient handling of problems during equipment operation.
[0026] Specifically, the communication module connects to the gas pressure sensor via the TSV protocol, with a direct connection transmission delay of less than 1μs. It also connects to the generator set controller via a CAN bus, the battery activator via the Modbus protocol, and external nodes via fiber optic cables for manual connection to external devices. This enables rapid and efficient data transmission, extending the functionality of the testing equipment and improving its utilization efficiency. The cloud-connected encryption module integrates several algorithm chips and also exchanges data via external protocols. The interface expansion module connects to a gas flow meter, temperature sensor, and relays. This ensures the effective collection of multiple data points during equipment operation, while also guaranteeing equipment security and enabling timely, accurate, and efficient handling of problems encountered during equipment operation.
[0027] In another embodiment of the invention, such as Figure 2As shown, a testing method for electrical instrument testing equipment is disclosed, including the following steps: S110, connecting the equipment and performing a self-test, connecting the testing equipment terminal to the gas pressure regulating station and connecting it to the power supply, and after powering on, testing the connection status of the main control unit, communication module, wide-temperature power management module and various component instruments, and recording the initial values; S120: Simultaneously collects multi-source data, records and monitors data information. In the communication module, it collects gas pressure sensor data through the TSV protocol, generator set controller data through the CAN bus, and battery activator data through the Modbus protocol. In the wide-temperature power management module, it collects instrument data through the interface expansion module and encrypts the collected multi-source data before uploading it to the main control unit. S130. Generate and process the report. The main control unit generates a detailed inspection log with timestamps from the multi-source data and checks whether there are discrepancies in the multi-source data. If there are, it continues to determine which type of discrepancy is which and then executes the linkage command or warning command. If there are no discrepancies, it is stored locally and uploaded to the cloud. At the same time, the discrepancy data results and processing information are included in the inspection log and sent to the cloud. S140. Equipment maintenance: Staff regularly inspect whether each module is operating normally. Staff remotely check the inspection log and verify whether the instrument data matches the actual equipment data. They also adjust the self-inspection standards based on the actual equipment operation.
[0028] This testing method ensures the collection of multiple data sources during equipment operation and facilitates online inspection by personnel. After connection, the equipment performs a power-on self-test. Once connected, the instrument indicator lights illuminate correctly, confirming a normal communication line and accurate data transmission. Personnel can view the data via mobile devices connected to the cloud. After a series of checks, the testing equipment begins collecting and recording data. The collected data is compared with instrument data for analysis. In step S120, the communication module collects multi-source data including: gas pressure, temperature, and flow information from the gas pressure sensor; generator output power, frequency, and speed information from the generator controller; and battery voltage, current, and internal resistance from the battery activator. Detailed data collection from relevant components allows the main control unit to analyze the data more comprehensively and accurately, leading to more precise adjustments to each module. Furthermore, in step S120, the multi-source data is encrypted and uploaded, and cannot be altered. It is stored in the cloud for verification, and users can only view it. This ensures the authenticity of the data available to personnel.
[0029] Specifically, in step S130, determining the type of data difference result includes: determining whether the current data difference result should trigger a linkage command or a warning command. If the gas pressure is below 0.35 MPa for 500 ms without a continuous decrease, and the data result reaches the warning command, then a warning reminder and corresponding manual adjustment operation will be performed. If the gas pressure drops sharply, and the linkage command is that the gas pressure exceeds the preset value of the warning command and continues to drop, then the following settings are set: if the gas pressure continues to drop sharply, the gas module will be accompanied by a reduction in power generation by the generator module to 60%, and the battery module will discharge to replenish 20% of the load. This avoids situations where staff cannot detect problems in a timely manner or cannot quickly and directly find the root cause of the problem and resolve it. This greatly improves work efficiency and saves the workload of staff. To enable staff to understand the data information more intuitively and clearly, the actual data is organized, and the frequency of data differences is reported, recording the frequency and specifications of report generation, thus meeting the inspection operation needs of staff in multiple ways.
[0030] This method for testing electrical instruments and meters utilizes a main control unit that receives equipment information and instrument datasets from the communication module and the wide-temperature power management module. This enables online testing during equipment operation without affecting normal operation. Based on the detected real-time data, the main control unit identifies discrepancies and anomalies, and generates warning and linkage instructions to handle specific situations, protecting equipment safety and addressing operational issues promptly, accurately, and efficiently. The main control unit also generates timestamped inspection logs, encrypting the data and logs before uploading them to the cloud for easy viewing. Users cannot directly modify the data, ensuring its authenticity and reliability. This reduces the workload of manual equipment inspection, avoids safety hazards associated with downtime checks, and promotes stable equipment operation.
