[0002] Currently, with social development and technological progress, more and more manufacturing companies are adopting energy isolation measures to ensure the personal safety of their workers.
[0003] However, the traditional energy isolation method involves the maintenance supervisor going to the operation center to track production. After production ends, the supervisor notifies each maintenance unit to collect their operation tags. Once the tags are collected, the supervisor notifies them to begin energy isolation and then to commence work. Traditional energy isolation equipment does not provide information on the isolation location. If external personnel participate in on-site maintenance, they may mistakenly lock their personal energy isolation maintenance locks in the wrong position, failing to ensure personal safety. Furthermore, when multiple people are performing maintenance, confusion may arise due to multiple locks being locked, reducing the efficiency of isolation point maintenance and potentially causing some isolation points to be overlooked, thus creating potential safety hazards.

[0020] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of safety production technology, and in particular relate to an energy isolation control method, device, electronic device and storage medium.
[0021] Currently, the traditional energy isolation method involves the maintenance supervisor going to the operation center to track production. After production ends, the supervisor notifies each maintenance unit to collect their operation tags. Once the tags are collected, the supervisor notifies them to begin energy isolation and then to commence work. However, traditional energy isolation equipment lacks information about the isolation location. If external personnel participate in on-site maintenance, they may mistakenly lock their personal energy isolation maintenance locks in the wrong position, failing to ensure personal safety. Furthermore, when multiple people are performing maintenance, confusion arises due to multiple locks being locked, reducing the efficiency of isolation point maintenance and potentially leading to the omission of certain isolation points, thus creating potential safety hazards.
[0022] Based on this, the embodiments of this application provide a control method, device, electronic device and storage medium for energy isolation. The embodiments provided by this application solve the technical problems in the prior art that fail to guarantee personal safety and are prone to confusion when multiple people are repairing, reducing the efficiency of isolation point repair and causing a certain isolation point to be missed, thus creating a safety hazard. The embodiments provided by this application improve the efficiency of energy isolation point repair while reducing the safety hazards that exist when multiple people are repairing.
[0023] Figure 1 A flowchart illustrating an energy isolation control method provided in an embodiment of this application is shown. Figure 1 As shown, the energy isolation control method includes the following steps: S101. After the production equipment performing the target production task stops, based on the shutdown signal of the production equipment and the preset maintenance time, the energy isolation display device is triggered to start the countdown of the preset maintenance time, and the energy isolation display device is controlled to issue the first voice broadcast reminder.
[0024] In this step, in the embodiment provided in this application, when the target production equipment completes shutdown and issues a shutdown signal, the energy isolation display device will receive the signal synchronously and, in conjunction with the preset maintenance duration parameter, automatically activate the countdown function module. At this time, the device immediately starts a dual status indication mechanism—its display screen dynamically displays the decreasing countdown of the preset maintenance duration, while triggering the first voice broadcast module to issue an acoustic prompt of "equipment is in isolation" and simultaneously lighting up the first indicator light.
[0025] Understandably, this process transforms shutdown signals into perceptible timing control commands through the coordinated response of hardware and software. This replaces the traditional startup method that relies on manual information transmission, establishing an automated time benchmark and safety warning basis for subsequent isolation operations. This process replaces the lag in traditional manual tracking of production status and hierarchical notification. By utilizing the logical association between shutdown signals and preset times, the startup of the energy isolation process is strictly aligned with the actual shutdown time of the equipment, ensuring a timely transition from production mode to maintenance mode. At the same time, voice broadcasts form the first layer of safety warning for on-site personnel.
[0026] In the embodiments provided in this application, the type and color of the first indicator light can be customized and used according to different application scenarios and usage conditions.
[0027] S102. Based on the preset energy isolation point map, perform point isolation locking operations on each preset energy isolation point.
[0028] In this step, in the embodiments provided in this application, the core of the locking operation for each preset energy isolation point based on the preset energy isolation point map lies in ensuring the accuracy of the energy isolation points through visual guidance and standardized processes. Specifically, this application will perform the locking operation for each preset energy isolation point according to the aforementioned preset energy isolation point map and using the work instruction manual. The core of the locking operation based on the preset energy isolation point map lies in ensuring the accuracy of isolation through visual guidance and standardized processes. The above process begins with the triggering of the operation card: when the construction workers on site receive a specific operation card according to the preset energy isolation point map shown on the display board of the energy isolation display device, the display board automatically lights up the operation card indicator associated with the operation card, forming an initial confirmation signal for human-computer interaction; subsequently, the locker and the verifier use energy isolation locks to lock each preset energy isolation point according to the energy equipment number marked on the preset energy isolation point map corresponding to each preset energy isolation point.
[0029] Understandably, during the locking process, the valves or power supplies are closed or powered off in sequence according to the isolation sequence indicated by the preset energy isolation point map. The uniformity of the numbering is used to avoid the locks being misplaced, and the path guidance of the preset energy isolation point map is used to prevent the omission of operations.
[0030] S103. After detecting that all preset energy isolation points have been isolated, control the energy isolation display device to issue a second voice broadcast reminder.
[0031] In this step, the embodiment provided in this application detects when the energy isolation key matching all locked energy isolation locks is placed into the preset storage space of the energy isolation display device by the micro switch in the preset storage space (i.e., the lock box) (this state change is characterized by the micro switch closing triggered by the energy isolation key returning to its position), and then determines that the energy isolation operation is completed.
[0032] Understandably, the embodiments provided in this application, through the collaboration of hardware sensing (microswitches) and logic control, transform the reset status of the physical energy isolation lock into a clear second voice broadcast reminder, thereby replacing the traditional method of relying on manual item-by-item verification and verbal notification, ensuring efficient and accurate feedback of the isolation completion status, and providing an automated safety confirmation mechanism for the initiation of subsequent maintenance work.
[0033] S104. When the countdown duration exceeds the preset duration threshold, control the energy isolation display device to issue a third voice broadcast reminder to unlock each preset energy isolation point.
[0034] In this step, when the countdown module of the energy isolation display device detects that the remaining time has dropped to a preset time threshold (i.e., the time threshold for unlocking), the embodiment provided in this application automatically activates the third voice broadcast reminder and issues a voice reminder of "Please release the energy isolation in time". This process realizes the conversion from time dimension to acoustic warning through the logic judgment of the countdown device, without the need for manual intervention.
[0035] Understandably, the above functions force a time constraint on the unlocking operation by establishing a hard link between preset time nodes and voice broadcasts. Essentially, they solve the problem of maintenance delays caused by traditional reliance on manual memory through time-series automated control.
[0036] S105. After all the energy isolation locks at each preset energy isolation point are successfully unlocked, the control stops the third voice broadcast reminder to complete the energy isolation of the production equipment.
[0037] In this step, according to the embodiment provided in this application, after the locker and the verifier confirm that all the life locks of the actual construction workers on site have been released, the second reset button is pressed to stop the third voice broadcast reminder. Then the life locks of the locker and the verifier are released again, and the key in the lockbox is taken out to unlock all the isolation points. At the same time, the first reset button is pressed to stop the second voice broadcast reminder, so as to complete the energy isolation of the production equipment.
[0038] It should be noted that, in the embodiments provided in this application, the technical solution presets the maintenance time in the energy isolation display device and starts the countdown module to monitor the logical relationship between the countdown duration and the preset duration threshold in real time. When the remaining countdown time is lower than the preset duration threshold (for example, a specific time window before the planned unlocking time), a third voice broadcast reminder is automatically triggered, and an unlocking operation instruction is issued to the target operators present. The preset timing logic is strictly followed, and the preset duration threshold is used as the triggering condition for the unlocking instruction. This replaces the traditional mode that relies on human experience judgment or verbal notification. By forming a time constraint on the unlocking operation through mandatory acoustic warnings, it ensures that all isolation points can start the unlocking process in an orderly manner before the end of the maintenance cycle, avoiding isolation timeouts due to forgetfulness or communication delays. This strengthens the standardization and timeliness control of maintenance operations from a time dimension.
[0039] In one embodiment, the energy isolation lock and the preset energy isolation specification text stored in the energy isolation display device are verified; it is determined whether the energy isolation lock and the preset energy isolation specification text are complete; after determining that the energy isolation lock and the preset energy isolation specification text are complete, the production equipment performing the target production task is stopped to start energy isolation.
[0040] It is understood that the embodiments provided in this application automatically trigger a quantity integrity check on the energy isolation locks stored in the preset storage space, and simultaneously verify the existence and accessibility of the preset energy isolation specification text (including electronic operating procedures or paper safety manuals).
[0041] Secondly, verification is performed based on the above test results: if the number of energy isolation locks fully matches the requirements of the preset isolation point map, and the specification text is in a callable state, then the resources are determined to be "complete". At this time, the production equipment executing the target production task is stopped, indicating that energy isolation can be performed at this time, that is, the conditions for energy isolation are met; otherwise, an abnormal alarm is generated and the process is interrupted.
[0042] Finally, the system only allows the next stage—that is, polling the production equipment executing the target production task in real time via the equipment status monitoring interface to see if it has output a valid shutdown signal—if no shutdown signal is detected, it continues to wait until the conditions are met; if a signal is detected, the subsequent countdown and voice broadcast process is immediately triggered.
[0043] This system completely replaces the traditional energy isolation lock and document verification operation mode with an automated verification mechanism, eliminating the risk of isolation operation interruption due to missing locks or omissions in the standard text from the source. Especially for multi-person collaboration scenarios, the systematic verification can avoid misjudgment of the number of locks due to unclear personnel handover, while ensuring the traceability of operation standards, establishing a complete material and knowledge foundation for subsequent isolation operations, and significantly improving the robustness of the overall process.
[0044] For example, based on a preset energy isolation point map, a point isolation locking operation is performed on each preset energy isolation point, including: Based on the preset energy isolation point map, determine the energy equipment number corresponding to each preset energy isolation point, and the lock number of the energy isolation lock corresponding to the energy equipment number; based on the lock number of the energy isolation lock, perform point isolation locking operation on the energy equipment at each preset energy isolation point, and sequentially execute valve closing or power-off operation.
[0045] First, based on the preset energy isolation point location map, a unique mapping relationship between the operation object and the lock is determined. Specifically, the construction personnel on site need to identify the energy equipment number corresponding to each preset energy isolation point according to the preset energy isolation point location map displayed on the energy isolation display device, and simultaneously determine the lock number of the energy isolation lock that is strictly bound to the energy equipment number. This step achieves the unification of the physical location of the equipment, the operation sign identification, and the lock number through the preset energy isolation point location map, ensuring the matching of subsequent operations.
[0046] Secondly, physical isolation operations are performed according to the lock numbers. On-site construction personnel retrieve the corresponding energy isolation lock from the lock storage area on the energy isolation display device according to the lock number, and then proceed to the energy equipment location marked on the preset energy isolation point map to perform physical isolation actions such as closing the valve or turning off the power in sequence. Each operation must ensure that the energy isolation lock body number, display board label, and isolation point number are completely consistent, and strictly follow the spatial order of the preset energy isolation point map to avoid skipping steps or omissions.
[0047] Finally, after confirming the integrity of the isolation through equipment status feedback and locking the preset energy isolation points, the target operator (i.e., the locker and the verifier) must return the energy isolation key corresponding to the energy isolation lock to the lock box in the preset storage space.
[0048] The micro switch built into the lock box detects the key's return status in real time: when the key triggers the micro switch to close, the system automatically determines that all preset energy isolation points have been isolated, then turns off the associated first indicator light (e.g., red), and simultaneously lights up the second indicator light (e.g., green) to indicate that isolation is complete, and triggers a second voice broadcast reminder. This process achieves automated verification of the physical operation status through the coordination of hardware sensing and logic control.
[0049] By providing spatial visualization guidance based on a pre-set energy isolation point map, verifying the consistency of triple numbering, and sequentially executing physical operations, the system solves the problems of misplaced locks and missed points that are prone to occur in traditional manual isolation. Especially in multi-person collaborative scenarios, the linkage mechanism between the operation tag retrieval and the indicator light status (such as lighting up the first indicator light after the operation tag is retrieved) can provide real-time feedback on task allocation progress, avoiding repetitive operations or blind spots of responsibility. Meanwhile, the automated detection of key return by microswitches replaces the lagging verification method of traditional manual lock counting, improving the efficiency and accuracy of judging the integrity of isolation. Ultimately, it achieves full-process error prevention control from drawing guidance to physical operation and status feedback, establishing a reliable safety barrier for subsequent maintenance work.
[0050] For example, based on a preset energy isolation point map, the energy device number corresponding to each preset energy isolation point and the lock number of the energy isolation lock corresponding to the energy device number are determined, including: Based on the preset energy isolation point location map, determine the operation card corresponding to each preset energy isolation point; after each operation card is received, control the operation card indicator light associated with the operation card to light up, and determine the energy equipment number corresponding to each preset energy isolation point, as well as the lock number of the energy isolation lock corresponding to the energy equipment number.
[0051] It should be noted that the embodiments provided in this application first clearly mark the operation tag identifiers corresponding to each preset energy isolation point through a visual display board. When the actual on-site construction workers take a specific operation tag according to the preset target maintenance task requirements, the energy isolation display device can immediately detect the physical state change of the operation tag leaving the preset storage position, and then automatically trigger the operation tag indicator light (e.g., a red indicator light) uniquely bound to the operation tag to light up. This process realizes the real-time capture of the operation tag taking action through the sensors (such as RFID or mechanical sensors) built into the display board, and maps out the corresponding energy equipment number, as well as the lock number of the energy isolation lock that strictly matches it.
[0052] Here, the binding relationship between the device number and the lock number has been digitally configured during initialization through preset energy isolation points to ensure that the operation sign identification, device number, and lock number form a one-to-one logical closed loop.
[0053] After the operator receives the operating plate and triggers the indicator light on the operating plate, the locker and the verifier locate the energy isolation lock with the same number in the lock storage area on the display board according to the equipment number displayed on the display board. This allows the locker and the verifier to only need to take the lock in the order of the lock numbers, thus avoiding taking the wrong one. The embodiment provided in this application will go to the area where the target energy equipment is located in sequence according to the spatial path indication of the preset energy isolation point location map to perform valve closing or power-off operations. After all isolation points are locked, the energy isolation lock key is returned to the lock box on the display board.
[0054] When all preset energy isolation points are locked and the energy isolation key is placed in the preset storage space on the energy isolation display device, the micro switch closes and immediately turns off the first indicator light (red), while simultaneously lighting up the second indicator light (green) that indicates that isolation is complete, and activating the second voice broadcast module to issue an acoustic reminder that "energy isolation is complete".
[0055] This implementation constructs a multi-layered error prevention mechanism by hard-linking the operation card retrieval with the indicator light status, strictly binding the device number with the lock number, and automating the key return verification via microswitches. This significantly improves the safety and efficiency of energy isolation operations. The real-time status feedback of the operation card indicator lights makes the task allocation progress transparent, while the clearly marked numbering at the lock storage location on the display board provides physical guidance for on-site construction personnel. The transparent document slot design on the display board of the energy isolation display device in the embodiment provided in this application ensures that the isolation task sheet is always visible, allowing the target personnel to verify the operational compliance in real time without opening the lock box, greatly improving supervision efficiency and operational transparency.
[0056] In one implementation, the isolation status of each preset energy isolation point is determined by the following method: receiving the state change of the micro switch in the preset storage space; when the energy isolation key matching all locked energy isolation locks is placed in the preset storage space on the energy isolation display device, and the energy isolation key triggers the micro switch to close, it is determined that all preset energy isolation points have been isolated, and the first indicator light representing isolation is turned off, and the second indicator light representing isolation completion is turned on, wherein the first indicator light and the second indicator light are different colors, and all energy isolation locks are matched with the same energy isolation key.
[0057] For example, the method also includes: The status of the first and second indicator lights is transmitted to the monitoring screen in the operation center. When the second indicator light illuminates, a confirmation signal indicating that energy isolation is complete is sent to the operation center.
[0058] First, the energy isolation display device continuously monitors the electrical status changes of the microswitches within the preset storage space. After the target operator completes the locking operation at each preset energy isolation point, the corresponding energy isolation key must be returned to the designated hook in the lock box. When the energy isolation key is returned to its original position, the mechanical displacement of its hook triggers the microswitch to generate a change in the level signal. The level signal controls the lighting and extinguishing of the first and second indicator lights. The lock box is then locked with the personal life locks of the locker and the verifier, thus providing preliminary physical sensing evidence for the integrity of the isolation.
[0059] Secondly, when all microswitches are detected to be in the closed state, the control module automatically determines that all preset energy isolation points have been isolated. At this time, the first indicator light (e.g., the red indicator light) indicating isolation is turned off; on the other hand, the second indicator light (e.g., the green indicator light) indicating isolation is completed is turned on, forming a visual warning switch.
[0060] Finally, after completing the above state transition, manual confirmation is required to strengthen safety redundancy. The specific confirmation method is as follows: after the person locking or verifying confirms that the lock and the second indicator light on the display board are correct, the first reset command is triggered (such as pressing the reset button on the display board), the residual signal of the second voice broadcast is terminated, and a log record is generated. At this time, the construction workers actually on site verify the status of the second indicator light and the isolation point map displayed on the display board. After confirming that the isolation is completed, the personal life lock is locked on the lock box, and the work can begin. The determination of the integrity of the isolation is strictly based on the automatic verification of physical sensing and preset parameters.
[0061] This application achieves automated and high-precision verification of isolation status, completely replacing the inefficient traditional model that relies on manual visual inspection or verbal notification.
[0062] The instant response characteristic of microswitches (millisecond-level delay) ensures that the status judgment is synchronized to the indicator light and the operation center in real time, avoiding safety blind spots caused by communication delays. At the same time, the dual-color design of the indicator light (such as red off and green on) provides intuitive on-site visual feedback, greatly reducing the probability of misjudgment.
[0063] Compared with the prior art, the energy isolation control method provided in this application, after the production equipment performing the target production task stops, triggers the energy isolation display device to start a countdown of the preset maintenance time based on the shutdown signal of the production equipment and the preset maintenance time, and controls the energy isolation display device to issue a first voice broadcast reminder. Then, based on the preset energy isolation point map, the lock operation of each preset energy isolation point is performed. After detecting that all preset energy isolation points have been isolated, the energy isolation display device is controlled to issue a second voice broadcast reminder. When the countdown duration is longer than the preset duration threshold, the energy isolation display device is controlled to issue a third voice broadcast reminder to unlock each preset energy isolation point. After all the life locks of all actual construction workers are released, the third voice broadcast reminder is stopped by the second reset button to complete the energy isolation of the production equipment. The embodiment provided in this application improves the efficiency of energy isolation point maintenance while reducing the safety hazards that exist when multiple people are performing maintenance.
[0064] Figure 2 A structural block diagram of an energy isolation control device provided in an embodiment of this application is shown. Figure 2 As shown, the energy isolation control device 200 includes: The trigger module 210 is used to trigger the energy isolation display device to start a countdown of the preset maintenance time based on the shutdown signal of the production equipment and the preset maintenance time after the production equipment performing the target production task stops, and to control the energy isolation display device to issue a first voice broadcast reminder.
[0065] The locking module 220 is used to perform point isolation locking operations on each preset energy isolation point based on a preset energy isolation point map.
[0066] The first control module 230 is used to control the energy isolation display device to issue a second voice broadcast reminder after detecting that all preset energy isolation points have been isolated.
[0067] The second control module 240 is used to control the energy isolation display device to issue a third voice broadcast reminder to unlock each preset energy isolation point when the countdown duration exceeds a preset duration threshold.
[0068] The third control module 250 is used to stop the third voice broadcast reminder after all the energy isolation locks at each preset energy isolation point are successfully unlocked, so as to complete the energy isolation of the production equipment.
[0069] For example, the energy isolation lock and the preset energy isolation specification text stored in the energy isolation display device are verified.
[0070] Determine if the energy isolation lock and the preset energy isolation specification text are complete.
[0071] After confirming that the energy isolation lock and the preset energy isolation specification text are complete, determine whether to shut down the production equipment performing the target production task in order to begin energy isolation.
[0072] For example, the locking module 220 is specifically used for: Based on the preset energy isolation point location map, determine the energy device number corresponding to each preset energy isolation point location, and the lock number of the energy isolation lock corresponding to the energy device number.
[0073] Based on the lock number of the energy isolation lock, the energy equipment at each preset energy isolation point is locked to isolate the point, and the valve is closed or the power is turned off in sequence.
[0074] For example, based on a preset energy isolation point map, the energy device number corresponding to each preset energy isolation point and the lock number of the energy isolation lock corresponding to the energy device number are determined, including: Based on the preset energy isolation point location map, determine the corresponding operation sign for each preset energy isolation point.
[0075] After each control panel is received, the indicator light associated with the control panel is turned on, and the energy device number corresponding to each preset energy isolation point and the lock number of the energy isolation lock corresponding to the energy device number are determined.
[0076] For example, the following method is used to determine whether all preset energy isolation points have been completely isolated: It receives the state changes of microswitches within the preset storage space.
[0077] When the energy isolation key matching all locked energy isolation locks is placed in the preset storage space on the energy isolation display device, and the energy isolation key triggers the micro switch to close, it is determined that all preset energy isolation points have been isolated, and the first indicator light indicating isolation is turned off, and the second indicator light indicating isolation completion is turned on. The first indicator light and the second indicator light are different colors. All energy isolation locks are matched with the same energy isolation key.
[0078] For example, after the second indicator light is turned on, the first reset command triggered by the target operator is obtained.
[0079] Based on the first reset command, the energy isolation display device is controlled to terminate the second voice broadcast reminder.
[0080] For example, the status of the first indicator light and the second indicator light is obtained and sent to the operation center monitoring screen.
[0081] When the second indicator light illuminates, a confirmation signal indicating that energy isolation is complete is sent to the operation center.
[0082] Compared with the prior art, the energy isolation control device 200 provided in this application embodiment, after the production equipment performing the target production task stops, triggers the energy isolation display device to start a countdown of the preset maintenance time based on the shutdown signal of the production equipment and the preset maintenance time, and controls the energy isolation display device to issue a first voice broadcast reminder. Then, based on the preset energy isolation point map, it performs point isolation locking operations on each preset energy isolation point. After detecting that all preset energy isolation points have been isolated and the keys matching each locked energy isolation lock have been returned to the preset storage space on the energy isolation display device, it controls the energy isolation display device to issue a second voice broadcast reminder. When the countdown duration exceeds the preset duration threshold, it controls the energy isolation display device to issue a third voice broadcast reminder to unlock each preset energy isolation point. After all the life locks of the construction workers are released, the third voice broadcast reminder is stopped by the second reset button, thus completing the energy isolation of the production equipment. The embodiment provided in this application improves the efficiency of energy isolation point maintenance while reducing the safety hazards that exist when multiple people are performing maintenance.
