Description

Technical Field

[0001] This application relates to the field of substation environmental control technology, and in particular to a GIS room environmental control method and system. Background Technology

[0002] With the continuous development of power grid construction, GIS (Gas Insulated Switchgear) equipment is being used more and more widely in power systems, and personnel operations are showing a trend towards intensification and efficiency. Because the SF6 (sulfur hexafluoride) gas widely used in GIS equipment decomposes under the influence of an electric arc to generate toxic gases such as hydrogen fluoride (HF) and low-fluorine compounds, which pose potential health hazards, relevant regulations clearly require that adequate ventilation and gas concentration testing be conducted before entering the GIS room to ensure the safety of operating personnel.

[0003] Currently, according to safety regulations, operators must arrive at the site after receiving a dispatch notification before manually starting the ventilation fan. Only then can they use a leak detector to check the SF6 gas concentration and carry out inspection or maintenance work. However, the existing procedure, which requires ventilation only after arrival at the site, prolongs the overall preparation time, causing equipment inspections to be unable to be completed within the specified time limit, thus affecting work efficiency and the execution of work plans. Summary of the Invention

[0004] The purpose of this application is to at least address one of the aforementioned technical deficiencies, particularly the technical deficiency of long adjustment time for the working environment of GIS rooms in the prior art.

[0005] Firstly, this application provides a GIS-based indoor environmental control method, the method comprising: Collect environmental parameter data of the GIS room, and close the access control when the environmental parameter data of the GIS room does not meet the preset environmental conditions. The environmental parameter data of the GIS room includes the SF6 gas concentration in the GIS room. Obtain the work tasks and priorities of the GIS room, and determine the ventilation duration of the GIS room based on the work tasks and priorities of the GIS room and the preset target SF6 gas concentration; Based on the ventilation duration of the GIS room, the air exchange equipment in the GIS room is driven to ventilate via wireless communication. When a command indicating that the ventilation of the air exchange equipment in the GIS room has ended is received, environmental parameter data of the GIS room after ventilation is collected. If the environmental parameters of the GIS room after ventilation do not meet the preset environmental conditions, the air conditioning equipment in the GIS room will be triggered to make supplementary adjustments until the environmental parameters of the GIS room meet the preset environmental conditions, and then the access control will be opened.

[0006] In one embodiment, the step of determining the ventilation duration of the GIS room based on the GIS room's work tasks and priorities, as well as a preset target SF6 gas concentration, includes: Determine the ventilation duration of the GIS room using the following expression:

[0007] in, For ventilation flow rate, The initial SF6 gas concentration in the GIS room, To preset the target SF6 gas concentration, Q This represents the maximum power of the air exchange equipment in the GIS room. Parameters are set for different priorities; when the GIS room task is of first priority, the air exchange equipment power is at its maximum value; when the GIS room task is of second priority, the air exchange equipment power is at its rated power; when the GIS room task is of third priority, the air exchange equipment power operates at half its rated power. If the calculated result is greater than 15 minutes, then the ventilation time for the GIS room should be taken as [value missing]. ,like If the calculated result is less than or equal to 15 minutes, then the ventilation time for the GIS room is taken as 15 minutes.

[0008] In one embodiment, the step of determining the ventilation duration of the GIS room based on the GIS room's work tasks and priorities, as well as a preset target SF6 gas concentration, includes: If the GIS room's work tasks are in manual operation mode, then the ventilation flow rate should be adjusted according to the following expression:

[0009] in, For the size of the indoor space in GIS, For the number of employees, The basic gas requirements for each worker.

[0010] In one embodiment, the step of driving the GIS room air exchange device for ventilation via wireless communication according to the GIS room ventilation duration includes: Based on the ventilation duration of the GIS room, equipment control commands are generated and sent to the equipment driver via wireless communication, so that the equipment driver can start the air exchange equipment for ventilation according to the equipment control commands. The wireless communication is a LoRa wireless communication network.

[0011] In one embodiment, after the step of sending device control commands to the device driver via wireless communication, the method further includes: If feedback information indicating that the air exchange equipment has failed to start is received from the device driver, the device driver will switch to manual mode to start the air exchange equipment for ventilation in manual mode.

[0012] In one embodiment, the GIS environmental parameter data includes the oxygen content and room temperature and humidity of the GIS room, and the GIS room air conditioning equipment includes an oxygen storage tank and a dehumidifier; if the GIS room environmental parameter data after ventilation does not meet the preset environmental conditions, a supplementary adjustment step is triggered for the GIS room air conditioning equipment, including: When the oxygen content after ventilation is detected to be insufficient to meet the preset environmental conditions, the oxygen storage tank is triggered to release oxygen and deliver it to the GIS room via the gas delivery pipeline; When the temperature and humidity of the GIS room after ventilation are detected to be inconsistent with the preset environmental conditions, the dehumidification equipment is activated so that the dehumidification equipment dries the air in the GIS room through internal circulation and then releases it back into the GIS room.

[0013] In one embodiment, the method further includes: When the environmental parameters of the GIS room meet the preset environmental conditions, the air exchange equipment in the GIS room will be driven to ventilate according to the default ventilation duration.

[0014] Secondly, this application provides a GIS-based indoor environmental control system, the system comprising: The GIS room environmental parameter data acquisition module is used to collect GIS room environmental parameter data and close the access control when the GIS room environmental parameter data does not meet the preset environmental conditions. The GIS room environmental parameter data includes the SF6 gas concentration in the GIS room. The GIS room ventilation duration determination module is used to obtain the GIS room work tasks and their priorities, and determine the GIS room ventilation duration based on the GIS room work tasks and their priorities, as well as the preset target SF6 gas concentration. The GIS room air exchange equipment drive module is used to drive the GIS room air exchange equipment to ventilate according to the GIS room ventilation time via wireless communication, and to collect the GIS room environmental parameter data after ventilation when it receives a command indicating that the GIS room air exchange equipment has finished ventilation. The GIS room air replenishment and adjustment module is used to trigger the GIS room air conditioning equipment to replenish and adjust the air if the environmental parameters of the GIS room after ventilation do not meet the preset environmental conditions, until the environmental parameters of the GIS room meet the preset environmental conditions and the access control is opened.

[0015] Thirdly, this application provides a storage medium storing computer-readable instructions, which, when executed by one or more processors, cause the one or more processors to perform the steps of any of the GIS room environmental control methods described in the above embodiments.

[0016] Fourthly, this application provides a computer device, including: one or more processors, and a memory; The memory stores computer-readable instructions, which, when executed by one or more processors, perform the steps of any of the GIS room environmental control methods described in the above embodiments.

[0017] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: The GIS room environmental control method provided in this application achieves pre-ventilation of the GIS room by collecting environmental parameters in advance and remotely controlling ventilation equipment before personnel arrive, avoiding the limitation of manual ventilation only after personnel arrive in the traditional process. This method calculates the required ventilation time based on the priority of the work task and the target SF6 gas concentration, and automatically collects environmental data after ventilation. If the conditions are not met, the air conditioning equipment is activated for supplementary adjustment until the environmental conditions meet the requirements before the access control is opened, thus ensuring environmental safety before personnel enter. This method effectively solves the problem of long adjustment time for the working environment of GIS rooms in existing technologies, significantly shortens the work preparation time, improves the efficiency of equipment inspection and maintenance, ensures the smooth execution of the work plan, and also enhances the safety of the workers.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a GIS-based indoor environmental control method. The following embodiments illustrate this method applied to computer equipment. It is understood that the computer equipment can be various devices with data processing capabilities, including, but not limited to, a single server, server cluster, personal laptop, desktop computer, etc. Figure 1 As shown, the method may include the following steps: S101: Collect environmental parameter data of the GIS room, and close the access control when the environmental parameter data of the GIS room does not meet the preset environmental conditions. The environmental parameter data of the GIS room includes the SF6 gas concentration in the GIS room.

[0022] The GIS room refers to a closed working environment equipped with gas-insulated switchgear, a dedicated space in the power system for the operation and maintenance of high-voltage equipment. Environmental parameter data refers to a set of data reflecting the current environmental conditions of the GIS room, specifically including but not limited to SF6 gas concentration, temperature and humidity, oxygen concentration, and the composition of harmful gases in the air. Preset environmental conditions are acceptable environmental threshold ranges pre-defined according to power safety regulations and human health and safety standards. SF6 gas concentration refers to the content of sulfur hexafluoride gas in the GIS room and is one of the core indicators for judging the environmental safety of the GIS room. Access control refers to the physical or electronic control system installed at the entrance and exit of the GIS room to control personnel access.

[0023] In this step, computer equipment configured in the GIS station periodically collects environmental parameter data through multiple sensor nodes deployed indoors, including at least real-time gas concentration data acquired by SF6 gas concentration sensors. The data is transmitted to the main control module of the environmental control system via wired or wireless means. The main control module has data analysis and judgment capabilities, and can compare the currently collected SF6 concentration with the system's built-in preset safety thresholds.

[0024] Furthermore, when the main control module determines that any of the current environmental parameters in the GIS room do not meet the preset environmental conditions, such as the SF6 gas concentration exceeding the allowable limit or other toxic gas residues not being completely eliminated, the main control module will immediately send a closing command to the access control unit through its control interface, so that the GIS room access control is closed or locked to prevent personnel from entering the room to work in an unsafe environment.

[0025] Furthermore, during the collection and comparison of environmental parameters, computer equipment can also access historical environmental change data from local or remote databases to predict trends. If the current environmental parameter trends indicate a potential for short-term deterioration, early warning information can be issued and access control systems can be kept closed.

[0026] To enhance practicality and responsiveness, the embodiment also includes a self-checking function for sensor status. For example, if a sensor uploads abnormal data or experiences a signal interruption, that parameter can be temporarily marked as unknown, and the system can determine whether to allow access control based on the remaining valid parameters, ensuring that the probability of misjudgment due to sensor failure is minimized.

[0027] By collecting environmental parameter data from the GIS room and closing access control when environmental parameters do not meet preset conditions, the indoor safety status can be accurately assessed before personnel enter the GIS room. Based on the actual environmental conditions, personnel entry and exit can be intelligently controlled to avoid safety hazards. Especially when SF6 gas decomposition products may not be completely eliminated, automatic door locking can effectively prevent personnel from accidentally entering the GIS room when environmental conditions are not met, thereby ensuring operational safety, improving response speed, and constructing a proactive environmental control mechanism.

[0028] S102: Obtain the work tasks and priorities of the GIS room, and determine the ventilation duration of the GIS room based on the work tasks and priorities of the GIS room, as well as the preset target SF6 gas concentration.

[0029] The GIS room work tasks refer to the categories of maintenance tasks identified during the scheduling process, primarily including three types: fault handling mode, manual mode, and machine mode. Priority refers to the urgency weight assigned to different task types to guide the priority adjustment order of environmental control. Fault handling mode is set as the first priority, manual mode as the second priority, and machine mode as the third priority. The preset target SF6 gas concentration refers to the maximum permissible SF6 gas concentration that must be achieved before personnel enter the GIS room, based on environmental safety standards, industry specifications, and operational requirements. The target SF6 gas concentration can be determined through target air quality values, and the ventilation duration refers to the duration of ventilation operations required to reduce the SF6 gas concentration in the GIS room to the target concentration.

[0030] In this step, after receiving a task instruction, the computer device parses the GIS room work task type contained within the instruction. This identification, based on the operation code or scheduling tag corresponding to the task, can accurately determine whether the current task belongs to fault handling mode, manual mode, or machine mode. After identification, the work task type is mapped to the corresponding priority weight, with fault handling mode assigned the first priority, manual mode the second priority, and machine mode the third priority. If the task is a composite task, the highest priority among them is selected as the overall priority of the currently executed task according to the priority coverage rule.

[0031] After identifying and prioritizing the task types, the environmental control strategy planning process begins. First, the computer equipment acquires real-time environmental data from the GIS room's environmental monitoring module, including SF6 gas concentration, oxygen content, air humidity, and other toxic gas concentrations, and compares it with preset target values. The target air quality value expression is as follows: ,in The target SF6 concentration (ppm). The target oxygen content (%). Target air humidity (%) The concentration of other toxic gases (ppm).

[0032] Based on the task priority and environmental deviation assessment results, the computer equipment invokes the ventilation strategy control module to dynamically generate ventilation time control parameters. High-priority tasks require a faster response time to environmental adjustments, and will be configured with stronger ventilation and shorter time windows to meet standards. If necessary, dehumidification, oxygenation, or toxic gas filtration equipment can be controlled in conjunction with these systems. For medium- and low-priority tasks, the ventilation time can be appropriately extended while ensuring safety, in order to optimize energy consumption and equipment operating efficiency.

[0033] By acquiring the work tasks and their priorities within the GIS room, the operational plan can be accurately grasped, and urgent tasks can be identified, thereby enabling the rational allocation of environmental control resources. By calculating ventilation duration based on preset target SF6 gas concentrations, the ventilation process can be precisely controlled according to actual task requirements, ensuring that environmental pretreatment meets safety standards while avoiding resource waste. Compared to traditional fixed ventilation time mechanisms, this method is more targeted and flexible, effectively shortening waiting time and improving emergency response efficiency.

[0034] S103: Based on the ventilation duration of the GIS room, drive the GIS room air exchange equipment to ventilate via wireless communication, and collect environmental parameter data of the GIS room after ventilation upon receiving an instruction indicating that the GIS room air exchange equipment has finished ventilating.

[0035] Wireless communication refers to the communication method established between computer equipment and GIS indoor air exchange equipment based on a wireless network, used to send control commands and receive feedback information. The GIS indoor air exchange equipment is an actuator used to regulate the air quality in the GIS room, with functions such as air exchange, ventilation, and gas exchange. The ventilation end command is a flag command actively sent by the air exchange equipment or triggered by the environmental monitoring module, used to notify the computer equipment that the ventilation operation has been completed.

[0036] In this step, the computer equipment first obtains the previously determined ventilation duration for the GIS room. This ventilation duration takes into account the type and priority of the current tasks in the GIS room, as well as the target SF6 concentration, to ensure that the obtained ventilation duration meets the actual operational safety requirements. Subsequently, the computer equipment sends a start command to the GIS room air exchange equipment via its built-in wireless communication module, including the ventilation duration parameter in the command, to drive the air exchange equipment to begin automatic ventilation operation.

[0037] To ensure a closed-loop control process, the air exchange equipment continuously transmits operational status information back to the computer after the ventilation task begins. The computer can monitor the start / stop status and any abnormal operating conditions of the air exchange equipment in real time. Simultaneously, timers can be set to track whether a preset ventilation time window has been reached. In one example, if a local air quality sensor is deployed in the GIS room, the ventilation duration can be dynamically adjusted based on the real-time compliance status of air parameters, achieving more flexible control.

[0038] After ventilation is completed, the air exchange equipment can automatically send a ventilation termination signal to the computer via wireless communication, or the environmental monitoring module can generate a termination signal after determining whether various environmental parameters have stabilized and reached their target values. Upon receiving the ventilation termination command, the computer immediately calls the environmental data acquisition module to sample the current environmental parameters of the GIS room, obtain updated data including SF6 concentration, oxygen content, humidity, and other toxic gases, and store them in the environmental database.

[0039] To further improve data availability, an automatic comparison mechanism can be configured to match and analyze the collected post-ventilation environmental parameters with target values, generating ventilation effect evaluation results as the basis for task decision-making and environmental control model optimization. In high-security scenarios, a re-inspection threshold can also be set. If any indicator is found to deviate from the preset target range, the short-term ventilation compensation process will be re-triggered to improve the steady-state reliability of environmental compliance.

[0040] The reason for controlling the ventilation equipment based on the ventilation duration of the GIS room is that the ventilation duration comprehensively considers the urgency of the current work task and the target air quality requirements, thus making the ventilation strategy targeted and timely. Using wireless communication to drive the ventilation equipment not only avoids the inconvenience of wiring or the reliability issues of contact control methods, but also improves flexibility and remote controllability. Collecting environmental data after ventilation ensures the verifiability of the ventilation effect, which is helpful for closed-loop control and operational decision optimization. Through this continuous control process, intelligent adjustment and precise maintenance of the GIS room's air quality can be achieved, improving ventilation efficiency and safety, and ultimately ensuring that GIS equipment maintenance and operation can be carried out smoothly under environmentally compliant conditions.

[0041] S104: If the environmental parameters of the GIS room after ventilation do not meet the preset environmental conditions, the air conditioning equipment in the GIS room will be triggered to make supplementary adjustments until the environmental parameters of the GIS room meet the preset environmental conditions, and then the access control will be opened.

[0042] Among them, GIS room air conditioning equipment refers to gas handling devices that are independent of the ventilation system. They can be used to finely adjust local environmental parameters such as concentration and humidity, such as dehumidification, oxygen injection, and air purification.

[0043] In this step, after the ventilation process is completed, the computer equipment acquires the latest environmental parameter data of the GIS room through the environmental parameter acquisition module and compares this data with the preset environmental conditions item by item. This comparison process can be implemented through predefined threshold comparison logic or machine learning models to determine whether the current environment meets the safety conditions for entry operations. If the comparison result shows that any environmental indicator does not meet the preset standard, the computer equipment will enter the environmental adjustment control process and send an adjustment command to the GIS room air conditioning equipment. This command includes the type of target indicator to be adjusted, the current value, the target value, and suggested adjustment strategy parameters, such as adjustment intensity and duration. After receiving the command, the air conditioning equipment performs the corresponding adjustment operation according to the type, such as activating the dehumidification module to reduce humidity or activating the air filtration module to reduce the content of toxic gases.

[0044] During the adjustment process, the computer equipment continuously monitors environmental change trends, periodically acquires updated environmental parameters, and determines whether the preset environmental conditions are met. If the conditions are still not met, supplementary adjustments can be continuously executed by gradually increasing the adjustment intensity or adjusting the strategy until all key parameters are within the target range.

[0045] Once the computer equipment confirms that all environmental parameters in the GIS room meet the preset environmental conditions, it will automatically trigger the access control module to unlock the door, allowing staff to enter the GIS room to carry out their tasks. Simultaneously, the data link of this adjustment process is recorded for use in optimizing adjustment strategies, assessing energy consumption, and modeling abnormal situations, thereby improving system responsiveness and decision-making accuracy.

[0046] Environmental parameters after ventilation are assessed, and if standards are not met, the air conditioning equipment is triggered to perform supplementary adjustments, ensuring that the GIS room has safe, stable, and compliant environmental conditions before access control is opened. This enables dynamic response compensation to complex or abrupt environmental factors, effectively compensating for the shortcomings of a single ventilation cycle. Real-time closed-loop control significantly improves environmental control accuracy, ensuring a safe environment before personnel enter and reducing accident risks. Furthermore, opening access control only after environmental indicators meet standards establishes an entry mechanism based on environmental compliance as a prerequisite, fundamentally guaranteeing the environmental safety of GIS room operation and maintenance.

[0047] In the above embodiments, by collecting environmental parameters in advance and remotely controlling ventilation equipment before personnel arrive, pre-ventilation of the GIS room is achieved, avoiding the limitation of manual ventilation only after personnel arrive in the traditional process. This method calculates the required ventilation time based on the task priority and target SF6 gas concentration, and automatically collects environmental data after ventilation. If the conditions are not met, air conditioning equipment is activated for supplementary adjustments until the environmental conditions meet the requirements before the access control is opened, thus ensuring environmental safety before personnel enter. This method effectively solves the problem of long adjustment time for the working environment of the GIS room in existing technologies, significantly shortens the work preparation time, improves the efficiency of equipment inspection and maintenance, ensures the smooth execution of the work plan, and also enhances the safety of the personnel.

[0048] In one embodiment, the step of determining the ventilation duration of the GIS room based on the work tasks and priorities of the GIS room, as well as a preset target SF6 gas concentration, includes: Determine the ventilation duration of the GIS room using the following expression:

[0049] in, For ventilation flow rate, The initial SF6 gas concentration in the GIS room, To preset the target SF6 gas concentration, Q This represents the maximum power of the air exchange equipment in the GIS room. Parameters are set for different priorities; when the GIS room task is of first priority, the air exchange equipment power is at its maximum value; when the GIS room task is of second priority, the air exchange equipment power is at its rated power; when the GIS room task is of third priority, the air exchange equipment power operates at half its rated power. If the calculated result is greater than 15 minutes, then the ventilation time for the GIS room should be taken as [value missing]. ,like If the calculated result is less than or equal to 15 minutes, then the ventilation time for the GIS room is taken as 15 minutes.

[0050] In this embodiment, the formula accurately calculates the required ventilation duration by comprehensively considering parameters such as the initial SF6 gas concentration in the GIS room, the preset target concentration, the ventilation flow rate, and the power of the air exchange equipment under different priorities. This ensures effective control of the indoor SF6 gas concentration while avoiding energy waste caused by over-ventilation. Simultaneously, it rationally adjusts the power of the air exchange equipment according to the needs of different priority tasks, enabling the air exchange equipment to operate flexibly under different priority tasks. This not only rapidly reduces the SF6 gas concentration to ensure the safety of personnel and equipment in emergencies but also saves energy to maintain indoor air quality within acceptable ranges, improving the flexibility and adaptability of the air exchange equipment. Furthermore, the application of this formula helps to promptly reduce the indoor SF6 gas concentration to a safe level, ensuring the safety of the working environment for staff and the normal operation and service life of GIS equipment. It also effectively reduces energy consumption while meeting ventilation requirements, optimizing energy utilization efficiency and meeting energy conservation and environmental protection requirements.

[0051] In one embodiment, the step of determining the ventilation duration of the GIS room based on the work tasks and priorities of the GIS room, as well as a preset target SF6 gas concentration, includes: If the GIS room's work tasks are in manual operation mode, then the ventilation flow rate should be adjusted according to the following expression:

[0052] in, For the size of the indoor space in GIS, For the number of employees, The basic gas requirements for each worker.

[0053] In this embodiment, when personnel are working, the ventilation flow rate is adjusted using this formula. This fully considers the impact of the GIS room size and the number of personnel on ventilation needs, making the operation of the air exchange equipment more in line with actual requirements. When personnel enter the GIS room, in addition to maintaining the indoor SF6 gas concentration at a safe level, it is also necessary to ensure that there is enough fresh air for personnel to breathe, avoiding the reduction of oxygen content and the accumulation of harmful gases due to personnel activity. The formula determines the basic ventilation volume based on the space size, ensuring basic air circulation and replacement indoors; increasing the ventilation volume according to the number of personnel precisely supplements the amount of air required for personnel breathing, effectively preventing problems such as oxygen deficiency and excessively high concentrations of harmful gases caused by insufficient ventilation. This provides a safe and healthy working environment for personnel, and also contributes to the stable operation of GIS equipment, reducing the risk of equipment failure due to environmental factors.

[0054] In one embodiment, the step of driving the GIS room air exchange device for ventilation via wireless communication according to the GIS room ventilation duration includes: Based on the ventilation duration of the GIS room, equipment control commands are generated and sent to the equipment driver via wireless communication, so that the equipment driver can start the air exchange equipment for ventilation according to the equipment control commands. The wireless communication is a LoRa wireless communication network.

[0055] The equipment control command is a control signal generated by the computer equipment based on parameters such as ventilation duration. It includes information such as control command type, execution time, equipment identifier, and execution parameters. The command content drives the target equipment to complete a specified function. The equipment driver is an execution module used to receive and parse the equipment control command and actually control the ventilation equipment. LoRa wireless communication network is a wireless communication network built on Low Power Wide Area Network (LPWAN) technology. It features long-distance transmission, low power consumption, and high anti-interference capabilities, making it suitable for industrial sites with enclosed structures and complex communication environments, such as GIS rooms, enabling reliable remote command transmission.

[0056] Specifically, after identifying the GIS room's work tasks and assessing the environment, the computer equipment determines the required ventilation duration based on the priority of current environmental indicators and task types. Subsequently, the computer equipment generates corresponding equipment control instructions based on the determined ventilation duration. These instructions include a unique identifier for the target equipment, the type of control behavior (e.g., start, duration, mode selection), a timestamp, and a checksum to ensure the instructions' recognizability and anti-interference capabilities in complex communication environments. The data structure of the equipment control instructions can be encapsulated using a preset format or protocol for rapid parsing and execution by the driver.

[0057] To achieve remote control, the computer equipment, through its integrated LoRa communication module, transmits the generated device control commands to the corresponding device driver in the GIS indoor environment via the LoRa wireless communication network. The use of LoRa networks enables stable signal transmission in enclosed or remote environments, avoiding wiring interference or signal obstruction issues.

[0058] After receiving the control command, the device driver parses the execution parameters of the ventilation operation based on the command content and controls the connected air exchange equipment to start operation according to the command. The air exchange equipment continues to run until the ventilation time is reached, or terminates prematurely upon receiving an interruption command. During execution, the device driver can periodically send status information back to the computer equipment to realize operational status monitoring and anomaly early warning.

[0059] Based on the ventilation duration of the GIS room, equipment control commands are generated and transmitted to the device driver for execution via LoRa wireless communication. This facilitates precise remote control of the air exchange equipment, enabling automatic adjustment of environmental parameters according to task requirements. Using LoRa wireless communication ensures reliable and timely command transmission without relying on cabling, making it suitable for applications such as GIS rooms that are structurally enclosed, remotely located, or have complex signal environments. This approach not only improves the intelligence and response speed of equipment control but also reduces system deployment and maintenance costs, and enhances environmental adaptability under various operation and maintenance modes.

[0060] In one embodiment, after the step of sending device control commands to the device driver via wireless communication, the method further includes: If feedback information indicating that the air exchange equipment has failed to start is received from the device driver, the device driver will switch to manual mode to start the air exchange equipment for ventilation in manual mode.

[0061] The feedback information is data generated by the device driver based on the device's operating status and transmitted back to the computer via a communication link. The feedback content may include successful startup, failure status, and fault codes. Manual mode refers to the mode where, when automatic mode fails, the computer controls the device driver to bypass the automatic control process using preset emergency control logic or through manual intervention, directly activating the air exchange equipment.

[0062] Specifically, after the computer device sends a control command to the device driver to start the air exchange equipment, it enters a status monitoring phase. During this phase, the computer device continuously monitors feedback information from the device driver to determine whether the device has started successfully as expected. This feedback information can be received via the LoRa wireless communication link, and its data format includes status flags, error codes, and timestamps, enabling a complete assessment of the device's status.

[0063] If the computer device parses the feedback information and finds a startup failure status indicator, or an error code indicating that the device is not responding or is malfunctioning, it immediately initiates a fault-tolerant logic process. In this process, the computer device automatically generates control commands for mode switching and sends them to the device driver via the communication module. The commands explicitly specify the execution content for switching to manual mode. Control of manual mode can be taken over by the local logic controller or by on-site personnel, providing an alternative operation path that does not rely on remote automatic control.

[0064] In manual mode, the device driver activates the corresponding control logic based on the received instructions, starting the air exchange equipment via a local signal source or default control program. If startup fails during this process, local maintenance personnel can be consulted to troubleshoot equipment malfunctions, ensuring timely execution of ventilation tasks in emergency situations. After ventilation is complete, the device driver can send the execution results and mode status back to the computer, enabling subsequent status synchronization and closed-loop system control.

[0065] Upon receiving a startup failure message from the device driver, the control device driver switches to manual mode to perform ventilation operations. This provides an effective emergency alternative in case of abnormalities in automatic mode, ensuring the continuous completion of critical environmental control tasks. By switching to manual mode, ventilation can continue without relying on the normal operation of the remote control system, thereby improving the overall system's operational reliability and task completion rate in the event of equipment failure or communication anomalies. This execution method ensures high fault tolerance for GIS room environmental control tasks, maintaining operational continuity under various abnormal conditions and avoiding shutdowns caused by control link failures or execution logic errors.

[0066] In one embodiment, the GIS environmental parameter data includes the oxygen content and temperature and humidity of the GIS room, and the GIS room air conditioning equipment includes an oxygen storage tank and a dehumidifier; if the GIS room environmental parameter data after ventilation does not meet the preset environmental conditions, a supplementary adjustment step is triggered for the GIS room air conditioning equipment, including: When the oxygen content after ventilation is detected to be insufficient to meet the preset environmental conditions, the oxygen storage tank is triggered to release oxygen and deliver it to the GIS room via the gas delivery pipeline; When the temperature and humidity of the GIS room after ventilation are detected to be inconsistent with the preset environmental conditions, the dehumidification equipment is activated so that the dehumidification equipment dries the air in the GIS room through internal circulation and then releases it back into the GIS room.

[0067] The oxygen storage tank is a container used to store high-purity oxygen and has a controllable release interface. It is connected to a gas delivery pipeline in the GIS room to achieve a quantitative oxygen supply. The gas delivery pipeline is a sealed flow channel for transporting oxygen; one end is connected to the oxygen storage tank, and the other end extends into the GIS room to introduce oxygen into the indoor environment. The dehumidification equipment is an air handling unit with humidity regulation capabilities, supporting internal air circulation. It reduces the humidity level in the air through technologies such as moisture absorption, condensation, or adsorption, and then releases the treated dry air back into the GIS room.

[0068] Specifically, the computer equipment continuously receives data on parameters such as oxygen content, temperature, and humidity after ventilation, collected by environmental sensors deployed indoors via the GIS system. The collected data is uploaded to the calculation module in real time and compared with pre-set target environmental thresholds to determine whether the current air conditioning meets the standards.

[0069] When the detection result shows that the oxygen content is below the set lower limit, the computer equipment automatically generates a control command to trigger oxygen supply and sends it to the oxygen storage tank control interface module via a wired or wireless communication network. Upon receiving the control signal, the oxygen storage tank activates the valve control unit, releasing oxygen into the gas delivery pipeline at a set flow rate. After being guided through the pipeline, the oxygen is evenly injected into the GIS room, thereby increasing the indoor oxygen concentration. During this process, the computer equipment can be set with a dynamic feedback mechanism to periodically detect changes in oxygen concentration to determine whether the set value has been reached. Once the set value is reached, a command to stop oxygen supply is issued, achieving closed-loop control.

[0070] If the computer determines that the temperature and humidity parameters after ventilation do not meet the preset conditions, especially if the humidity exceeds the upper limit, it will prioritize activating the indoor dehumidifier in the GIS room. The computer sends a start command to the dehumidifier, which includes parameters such as dehumidification mode, processing time, or power level. After receiving the command, the dehumidifier draws air from the GIS room into its unit through an internal circulating fan. After condensation, moisture absorption, or drying, the dried air is returned to the GIS room, thus reducing the humidity. The computer can dynamically adjust the dehumidification power or execution time based on real-time humidity feedback data to ensure that the final humidity returns to the set range.

[0071] Furthermore, oxygen replenishment and temperature / humidity adjustment are executed simultaneously as parallel tasks, and the computer equipment has the capability to concurrently control and monitor the status of multiple air conditioning devices. To improve the robustness of equipment startup, a retry mechanism is implemented after the startup command is issued. If a device startup failure is detected, the computer equipment will wait for a preset time interval and then issue the same action command again to attempt a restart. If no valid response is received or a timeout message is returned, the adjustment module is deemed to be faulty, and it is automatically switched to manual control mode to prevent continuous failures from causing other control anomalies. Simultaneously, a multi-channel parallel monitoring strategy is adopted for equipment startup; that is, the device that first returns to a normal state is prioritized for startup. Devices not in a normal state are prevented from continuing to participate in automatic task scheduling and are switched to manual mode management until they are manually repaired and restored, at which point they are reintegrated into the automatic control scope. This effectively improves task execution efficiency and stability, and avoids delays in the overall adjustment process due to individual device failures.

[0072] In this embodiment, by detecting the environmental parameters of the GIS room after ventilation and triggering oxygen release and activating dehumidification equipment when oxygen content or humidity is abnormal, automatic compensation and adjustment of the GIS room's air environment can be effectively achieved. When oxygen content is insufficient, the oxygen storage tank is automatically controlled to release oxygen, helping to maintain a suitable oxygen concentration indoors, thereby protecting personnel health and meeting equipment operating requirements. When humidity exceeds the standard, the dehumidification equipment is activated, preventing potential hazards such as equipment corrosion and insulation degradation caused by excessive humidity inside the GIS room.

[0073] In one embodiment, the method further includes: When the environmental parameters of the GIS room meet the preset environmental conditions, the air exchange equipment in the GIS room will be driven to ventilate according to the default ventilation duration.

[0074] The default ventilation duration refers to a standardized ventilation duration predefined to maintain the continuous stability of the GIS room environment when it is within the preset standard.

[0075] Specifically, the computer equipment continuously collects indoor environmental parameter data from the GIS and compares and analyzes this data with preset environmental conditions stored in the database. Once it is determined that all key parameters meet the preset standards, the GIS room is deemed to be in a safe state, capable of maintaining the existing gas concentration, temperature, and humidity levels. Under this premise, no supplementary adjustments are required; instead, a default ventilation strategy is adopted based on maintaining air circulation and preventing localized gas accumulation.

[0076] Subsequently, the computer device automatically retrieves the default ventilation duration configuration data based on its built-in control logic and generates a control command containing information such as the start signal and ventilation duration, for example, setting the default ventilation duration to 15 minutes. This command is sent to the device driver via the wireless communication module. Upon receiving the control command, the device driver immediately controls the air exchange equipment to begin ventilation operation.

[0077] During ventilation, the computer equipment can choose to continue collecting environmental parameter data to ensure that the environment remains stable; if environmental fluctuations exceed the warning threshold during ventilation, the current ventilation can be immediately interrupted and a higher-level environmental control process can be initiated.

[0078] In this embodiment, the operation of the air exchange equipment is still executed even when the environmental parameters meet the preset conditions because it is based on considerations of maintaining stable airflow and preventing the accumulation of pollutants. Default ventilation is used to maintain the microenvironmental stability of the GIS room. By adopting a default ventilation duration, frequent checks on whether to turn the equipment on can be avoided, improving overall operating efficiency and reducing resource consumption. Simultaneously, performing short-term ventilation under no load adjustment conditions helps extend equipment lifespan, reduce failure rates, and enhance stability and controllability during long-term operation. This method ensures dynamic airflow while maintaining environmental safety, effectively improving the accuracy and safety assurance capabilities of environmental quality control.

[0079] To facilitate understanding of the scheme in this application, specific examples are provided below.

[0080] like Figure 2 As shown, upon startup, the system first acquires and determines the task. If the task is a single task, its priority is immediately determined; if it is a multi-task, comprehensive calculations and adjustments to the handling method are performed before prioritization. Fault handling mode is the first priority, manual mode the second, and machine mode the third. After priority is determined, the system acquires environmental variables, collecting key data such as SF6 gas concentration, oxygen content, temperature, and humidity. Next, it determines whether the system is in manual operation mode. If not, the corresponding ventilation time is calculated based on the previously determined priority; if so, the ventilation flow rate is adjusted. The ventilation time is recalculated using the adjusted flow rate. After ventilation, environmental variables are acquired again to verify whether the environmental parameters meet the standards. If the parameters do not meet the requirements, a supplementary system is activated, such as supplementing oxygen, while simultaneously coordinating with the temperature and humidity control system for appropriate adjustments until the environment meets the predetermined standards. Once the environmental parameters meet the requirements, access is opened, allowing personnel to enter or the equipment to operate normally.
