Description

Technical Field

[0001] The present invention relates to the technical field of equipment operation and maintenance, and in particular to a digital operation and maintenance system for electromechanical facilities for highways. Background Art

[0002] In the process of highway maintenance, there are a large number of electromechanical assets and fire extinguishers involved. There are certain differences in equipment categories, models, specifications, and installation locations. The design service life ranges from 2 to 10 years, and the design service life of some equipment even exceeds 20 years. When electromechanical equipment fails, the faulty equipment is repaired or replaced instead of the overall replacement of equipment of the same type and age. This results in different life cycles for the same type of equipment. Although a replacement ledger is established in the daily management process, due to employee changes and long-term accumulation, there are discrepancies between the account and the actual situation, which is difficult to trace. Secondly, the existing management method of fire extinguishers in highway maintenance is generally manual inspection and manual recording. Generally, in the southern mountainous areas, a highway maintenance unit needs to be responsible for the management of nearly 100 tunnels, involving tens of thousands of fire extinguishers, all of which need to rely on personnel inspection and filling in cards. There are problems such as long inspection time, large workload, and waste of labor. With the demand for the development of digital information technology in enterprises, it has become an urgent problem to realize the full life cycle management of electromechanical equipment and the information inspection of fire extinguishers through information management means. Summary of the invention

[0003] In view of the deficiencies in the prior art, the technical problem solved by the present invention is to provide a digital operation and maintenance system for electromechanical facilities for highways, so as to solve the problem that the operation and maintenance management workload of electromechanical equipment on existing highways is large and the information of all electromechanical equipment cannot be obtained in a timely and accurate manner.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is: a digital operation and maintenance system for electromechanical facilities for highways, including a data storage module, a data detection module, a data receiving module, a data storage module, an operation and maintenance task formulation module, an inventory management module, an inspection terminal and an operation and maintenance terminal;

[0005] The data storage module is used to store and update the electromechanical equipment ledger and fire extinguisher ledger according to the inspection data. The electromechanical equipment ledger includes equipment category, equipment technical parameters, installation location, equipment inspection records, and operation and maintenance records; the fire extinguisher ledger includes fire extinguisher type, fire extinguisher parameters, installation location, and fire extinguisher inspection records and filling records.

[0006] The data detection module is used to detect whether there is an abnormality in the electromechanical equipment data. If there is an abnormality, an inspection task is generated according to the equipment abnormality information and sent to the inspection terminal; the data receiving module is used to receive the inspection terminal data to generate an inspection record and synchronize it to the data storage module, and the operation and maintenance task formulation module formulates the operation and maintenance task according to the inspection record and sends it to the operation and maintenance terminal;

[0007] The inventory management module includes an inventory recording unit, an inventory warning unit, and an inventory coordination unit. The inventory recording unit is used to record the information of the spare parts in and out of each inventory point and generate an inventory ledger; the inventory warning unit is used to sequentially determine whether the quantity of each type of spare parts in each inventory point is lower than a first threshold and higher than a second threshold. If the judgment result is yes, the spare parts of this type are marked as a first type of spare parts to be replenished. If the judgment result is no, it is further determined whether the spare parts of this type are lower than the second threshold. If so, the spare parts of this type are modified to a second type of spare parts to be replenished, and a second-level inventory warning is issued to the operation and maintenance terminal;

[0008] The inventory coordination unit is used to determine whether the number of spare parts of this type in other inventory points within the first range value near the inventory point is greater than the first threshold value. If the judgment result is yes, the mark of a type of spare parts to be replenished of this type of spare parts is modified to a coordinated part, and the information of other inventory points that meet the conditions is associated with this type of spare parts. If the judgment result is no, no modification is made and a first-level inventory warning is issued to the operation and maintenance terminal.

[0009] The beneficial effects of this program are:

[0010] By establishing an electronic ledger of electromechanical equipment and fire extinguishers, and updating the ledger of electromechanical equipment and fire extinguishers in real time based on inspection records and maintenance records, operation managers and maintenance service personnel can fully, accurately and timely grasp the type and status of electromechanical equipment and fire extinguisher information. The data detection module can timely detect whether there are abnormalities in electromechanical equipment, so that abnormal equipment can be inspected in time, and operation and maintenance tasks can be formulated based on inspection records, so that faulty equipment can be repaired in time, ensuring the use of electromechanical equipment and improving the utilization efficiency of electromechanical equipment; it can enable highway operation managers to dynamically manage the entire life cycle of electromechanical equipment.

[0011] In terms of spare parts inventory management, there are many types of electromechanical system equipment, complex operating environments, and high requirements for key node equipment security. Spare parts are managed uniformly through inventory records, from the purchase and warehousing of spare parts to the management of the entire process of material transfer, and detailed records and registration of detailed information and performance indicators of various spare parts are made, so that operation and maintenance managers can easily query and inventory, and can easily call when equipment fails; secondly, the inventory early warning module issues an early warning for spare parts that are insufficient and cannot be allocated from neighboring inventory points, thereby reminding relevant personnel to replenish the corresponding spare parts in time; and through the inventory collaboration unit, spare parts from different inventory points can be called on each other, thereby reducing unnecessary inventory backlogs, reducing storage costs and capital occupation; traditional warehouses Inventory management can only count the number of spare parts at the inventory point, and only issue an early warning for the number of a single inventory point, which will lead to the continuous consumption and replenishment of spare parts at a single inventory point, while other adjacent inventory points have a backlog of goods and the problem of low efficiency in the use of spare parts; and this solution does not replenish the spare parts when the spare parts are only lower than the first set threshold and can be transferred from adjacent inventory points, thereby improving the efficiency of goods use at adjacent stocking points. When the spare parts are lower than the second set threshold, this type of spare parts is very small and cannot meet the timeliness requirements of emergency maintenance. Transferring from adjacent inventory points will delay maintenance time. Therefore, a secondary inventory early warning is issued for spare parts lower than the second set threshold, so that the operation and maintenance end can replenish the stock in time to ensure maintenance efficiency.

[0012] Furthermore, the data storage module is also used to package data such as equipment type, equipment brand, fault cause, spare parts for the fault, etc. to generate a data packet; it also includes a data analysis module, which is used to extract all data packets stored in the cycle, analyze the relationship between the faulty equipment, the fault cause and the spare parts for the fault, and generate a fault relationship table; the inventory management module also includes a procurement analysis unit, which is used to obtain the demand quantity of various spare parts in the next cycle based on the fault relationship table combined with all the equipment types, brands and quantities currently in use, through a pre-trained demand forecasting model, and generate a procurement plan.

[0013] The purchasing analysis unit automatically generates a purchasing plan based on the forecast results, which reduces the time and effort of manually preparing purchasing plans and improves purchasing efficiency. Through accurate demand forecasting, inventory levels can be better controlled, unnecessary inventory backlogs can be reduced, and storage costs and capital occupation can be reduced. At the same time, sufficient spare parts can be ensured to meet the needs of equipment repair and maintenance, improving equipment reliability and availability.

[0014] Furthermore, it also includes an equipment quality analysis module, which is used to extract all data packets stored in a cycle, and use a pre-trained equipment life prediction model to derive the type, brand and quantity of equipment that needs to be replaced in the next cycle, and generate a pre-replacement equipment information list. The procurement analysis unit is also used to update the required quantity of various spare parts in the next cycle according to the pre-replacement equipment information list.

[0015] By predicting the life of the equipment in use, we can determine the equipment that may be replaced in the future. In this case, there will be basically no demand for spare parts for these equipment that are about to be retired in the next cycle. Therefore, the spare parts demand data for the next cycle can be updated based on the information of the replaced equipment, thereby improving the accuracy of the prediction of the demand quantity of various spare parts in the next cycle.

[0016] Furthermore, the operation and maintenance task formulation module includes a fault analysis unit, a demand analysis unit, a task generation unit, and a task dispatching unit. The fault analysis unit obtains the type of faulty equipment, the cause of the fault, the number of faulty equipment, and the location of the faulty equipment based on the inspection record; the demand analysis unit is used to derive a spare parts demand list based on the type of faulty equipment, the cause of the fault, the number of faulty equipment and in combination with the fault relationship table; the task generation unit is used to generate an operation and maintenance task based on the type of faulty equipment, the number of faulty equipment, and the location of the faulty equipment; the task dispatching unit is used to determine the inventory point that meets the requirements based on the spare parts demand list, and determine the nearest operation and maintenance end based on the inventory point location and the faulty equipment location, and dispatch the operation and maintenance task to the operation and maintenance end.

[0017] By analyzing the type, cause and number of faulty equipment, and combining the fault relationship table, we can quickly obtain a list of spare parts requirements to ensure that the required spare parts can be quickly called up when equipment fails. We can determine the nearest operation and maintenance terminal based on the location of the inventory point and the location of the faulty equipment, and assign the operation and maintenance tasks to the operation and maintenance terminal, thus shortening the maintenance response time.

[0018] Furthermore, the device quality analysis module also includes a device quality assessment unit, which is used to extract all data packets stored in a period and statistically obtain a device quality ranking table, which includes device type, device brand, and number of device failures.

[0019] The equipment quality ranking table can clearly compare the quality performance of similar equipment provided by different suppliers. The ranking table usually conducts a comprehensive evaluation based on multiple dimensions such as equipment maintenance frequency and failure rate. By analyzing these data, the operation and maintenance party can identify which suppliers' equipment performs better in actual applications, thereby providing a scientific basis for the next purchase decision. For example, if a certain brand of surveillance cameras has almost no failures in the past year, while similar products of another brand have frequent problems, then the operation and maintenance party may tend to choose the former when purchasing next time. In addition, such a ranking table can also help to discover whether there are common problems with a specific model or batch of products, and then communicate with the supplier to resolve or avoid purchasing the same model of products in the future.

[0020] Furthermore, the data detection module is also used to obtain the data fluctuation state of the device judged to be faulty within a preset period before the abnormal data appears, and to obtain multiple data fluctuation states of the same type of normal equipment, and input the data fluctuation states of the above-mentioned faulty equipment and normal equipment into the pre-analysis model for training to obtain a trained pre-analysis model; the data detection module is also used to determine through the pre-analysis model whether the collected data fluctuation state is the data fluctuation state before the abnormal data appears. If the judgment result is yes, an inspection task is generated according to the equipment information associated with the data fluctuation and sent to the inspection terminal. If the judgment result is no, no processing is performed.

[0021] By continuously monitoring the data during the operation of the equipment, when similar data fluctuations are detected before the abnormal data that caused the failure in the past are generated, it means that the equipment may be about to face similar problems or failures. Therefore, before the abnormal data is generated, an inspection task is generated to check the equipment in advance, and the spare parts for related maintenance are dispatched in advance, so as to carry out early operation and maintenance of the equipment before the failure occurs. This proactive maintenance strategy can not only effectively avoid production interruptions caused by sudden failures and reduce unplanned downtime, but also significantly improve the overall operating efficiency and stability of the equipment. More importantly, by implementing preventive maintenance measures, the problem can be solved before it really affects production efficiency, thereby greatly extending the service life of the equipment and reducing long-term operating costs.

[0022] Furthermore, the procurement analysis unit is also used to obtain spare parts information marked as the second type of spare parts to be replenished, and send a deployment request to the corresponding supplier. By deploying a smaller number of spare parts, that is, spare parts that are already below the second set threshold, the pre-replenishment of spare parts is achieved. This ensures that there are corresponding spare parts to use during equipment failure operation and maintenance, avoiding the failure to obtain spare parts in time to affect equipment failure repair and cause greater losses. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1This is a schematic diagram of the system modules of Example 1.

[0024] Figure 2 This is a schematic diagram of the structure of the fire extinguisher management module of Example 2. DETAILED DESCRIPTION

[0025] The following is further described in detail through specific implementation methods:

[0026] Embodiment 1 is basically as attached Figure 1 As shown: A digital operation and maintenance system for electromechanical facilities for highways, including a data storage module, a data detection module, a data receiving module, a data storage module, an operation and maintenance task formulation module, an inventory management module, an inspection terminal and an operation and maintenance terminal;

[0027] The data storage module is used to store and update the electromechanical equipment ledger and fire extinguisher ledger according to the inspection data. The electromechanical equipment ledger includes equipment category, equipment technical parameters, installation location, equipment inspection records, and operation and maintenance records; the fire extinguisher ledger includes fire extinguisher type, fire extinguisher parameters, installation location, and fire extinguisher inspection records and filling records.

[0028] The data detection module is used to detect whether there is an abnormality in the electromechanical equipment data. If there is an abnormality, an inspection task is generated according to the equipment abnormality information and sent to the inspection terminal; the data receiving module is used to receive the inspection terminal data to generate an inspection record and synchronize it to the data storage module, and the operation and maintenance task formulation module formulates the operation and maintenance task according to the inspection record and sends it to the operation and maintenance terminal;

[0029] The inventory management module includes an inventory recording unit, an inventory warning unit, and an inventory coordination unit. The inventory recording unit is used to record the information of the spare parts in and out of each inventory point and generate an inventory ledger; the inventory warning unit is used to determine in turn whether the quantity of each type of spare parts in each inventory point is lower than the first threshold and higher than the second threshold. If the judgment result is yes, the spare parts of this type are marked as first-class parts to be replenished. If the judgment result is no, it is further determined whether the spare parts of this type are lower than the second threshold. If so, the spare parts of this type are modified to second-class parts to be replenished, and a second-level inventory warning is issued to the operation and maintenance terminal;

[0030] The inventory coordination unit is used to determine whether the number of spare parts of this type in other inventory points within the first range value near the inventory point is greater than the first threshold value. If the judgment result is yes, the mark of a type of spare parts to be replenished of this type of spare parts is modified to a coordinated part, and the information of other inventory points that meet the conditions is associated with this type of spare parts. If the judgment result is no, no modification is made and a first-level inventory warning is issued to the operation and maintenance terminal.

[0031] Through the unified management of spare parts through inventory records, from the purchase and storage of spare parts to the management of the entire process of material transfer, the detailed information and performance indicators of various spare parts are recorded in detail, so that the operation and maintenance management personnel can easily query and inventory, and can easily call when the equipment fails; secondly, through the inventory warning module, warnings are issued for spare parts that are insufficient and cannot be allocated from neighboring inventory points, so as to remind relevant personnel to replenish the corresponding spare parts in time; and through the inventory coordination unit, spare parts from different inventory points can be called by each other, thereby reducing unnecessary inventory backlogs, reducing storage costs and capital occupation; traditional inventory management can only count the number of spare parts at the inventory point, only If an early warning is issued for the quantity of a single inventory point, the spare parts of the single inventory point will be continuously consumed and replenished, while other adjacent inventory points will have a backlog of goods and the spare parts utilization efficiency will be low. However, this solution does not replenish the spare parts when the spare parts are only lower than the first set threshold and can be transferred from adjacent inventory points, thereby improving the utilization efficiency of goods at adjacent stocking points. When the spare parts are lower than the second set threshold, it is said that there are very few spare parts of this type and it is impossible to meet the timeliness requirements of emergency maintenance. Transferring from adjacent inventory points will delay maintenance time. Therefore, a secondary inventory early warning is issued for spare parts lower than the second set threshold, so that the operation and maintenance end can replenish the stock in time to ensure maintenance efficiency.

[0032] The data storage module is also used to package data such as equipment type, equipment brand, fault cause, spare parts for fault, etc. to generate a data packet; it also includes a data analysis module and an equipment quality analysis module. The data analysis module is used to extract all data packets stored in the cycle, analyze the relationship between faulty equipment, fault cause and spare parts for fault, and generate a fault relationship table; the equipment quality analysis module is used to extract all data packets stored in the cycle, and use a pre-trained equipment life prediction model to obtain the type, brand and quantity of equipment to be replaced in the next cycle, and generate a pre-replacement equipment information list; the inventory management module also includes a procurement analysis unit. The procurement analysis unit is used to obtain the demand quantity of various spare parts in the next cycle based on the fault relationship table combined with all the equipment types, brands and quantities currently in use, and use a pre-trained demand prediction model, and generate a procurement plan; it is also used to update the demand quantity of various spare parts in the next cycle based on the pre-replacement equipment information list.

[0033] The procurement analysis unit automatically generates a procurement plan based on the forecast results, reducing the time and effort of manually preparing procurement plans and improving procurement efficiency. Through accurate demand forecasting, inventory levels can be better controlled, unnecessary inventory backlogs can be reduced, and storage costs and capital occupation can be reduced. At the same time, it ensures that there is sufficient supply of spare parts to meet the needs of equipment repair and maintenance, and improves the reliability and availability of equipment. By predicting the life of the equipment in use, it is possible to obtain equipment that may be replaced in the future. In this case, these equipment that are about to be retired will basically no longer have spare parts demand in the next cycle. Therefore, the spare parts demand data in the next cycle can be updated based on the information of the replaced equipment, and the accuracy of the forecast of the demand quantity of various spare parts in the next cycle can be improved.

[0034] The equipment quality analysis module also includes an equipment quality assessment unit, which is used to extract all data packets stored in the cycle and statistically obtain an equipment quality ranking table, which includes equipment type, equipment brand, and number of equipment failures. By analyzing these data, the operation and maintenance party can identify which suppliers' equipment performs better in actual applications, thereby providing a scientific basis for the next procurement decision. The procurement analysis unit is also used to obtain spare parts information marked as Class II parts to be replenished, and send a deployment request to the corresponding supplier. By allocating spare parts with a small quantity, that is, spare parts that are already below the second set threshold, pre-replenishment of spare parts is achieved.

[0035] The operation and maintenance task formulation module includes a fault analysis unit, a demand analysis unit, a task generation unit, and a task dispatching unit. The fault analysis unit obtains the type of faulty equipment, the cause of the fault, the number of faulty equipment, and the location of the faulty equipment based on the inspection record; the demand analysis unit is used to obtain a spare parts demand list based on the type of faulty equipment, the cause of the fault, the number of faulty equipment and the fault relationship table; the task generation unit is used to generate an operation and maintenance task based on the type of faulty equipment, the number of faulty equipment, and the location of the faulty equipment; the task dispatching unit is used to determine the inventory point that meets the requirements based on the spare parts demand list, and determine the nearest operation and maintenance end based on the inventory point location and the faulty equipment location, and dispatch the operation and maintenance task to the operation and maintenance end.

[0036] By analyzing the type, cause and number of faulty equipment, and combining the fault relationship table, we can quickly obtain a list of spare parts requirements to ensure that the required spare parts can be quickly called up when equipment fails. We can determine the nearest operation and maintenance terminal based on the location of the inventory point and the location of the faulty equipment, and assign the operation and maintenance tasks to the operation and maintenance terminal, thus shortening the maintenance response time.

[0037] The data detection module is also used to obtain the data fluctuation state of the device judged to be faulty within a preset period before the abnormal data appears, and to obtain multiple data fluctuation states of the same type of normal equipment, and input the data fluctuation states of the above-mentioned faulty equipment and normal equipment into the pre-analysis model for training to obtain a trained pre-analysis model; the data detection module is also used to determine through the pre-analysis model whether the collected data fluctuation state is the data fluctuation state before the abnormal data appears. If the judgment result is yes, an inspection task is generated according to the equipment information associated with the data fluctuation and sent to the inspection terminal. If the judgment result is no, no processing is performed.

[0038] By continuously monitoring the data during the operation of the equipment, when similar data fluctuations are detected before the abnormal data that caused the failure in the past are generated, it means that the equipment may be about to face similar problems or failures. Therefore, before the abnormal data is generated, an inspection task is generated to check the equipment in advance, and the spare parts for related maintenance are dispatched in advance, so as to carry out early operation and maintenance of the equipment before the failure occurs. This proactive maintenance strategy can not only effectively avoid production interruptions caused by sudden failures and reduce unplanned downtime, but also significantly improve the overall operating efficiency and stability of the equipment. More importantly, by implementing preventive maintenance measures, the problem can be solved before it really affects production efficiency, thereby greatly extending the service life of the equipment and reducing long-term operating costs.

[0039] like Figure 2 As shown, the similarities between Example 2 and Example 1 are not repeated here, and the difference is that it also includes a fire extinguisher management module, and the inspection records received by the data receiving module include fire extinguisher inspection records; the fire extinguisher management module includes a validity period determination unit, a fire information monitoring unit, and a fire extinguisher scheduling unit; the validity period determination unit is used to calculate the effective time of the fire extinguisher according to the fire extinguisher information, and to update the effective time according to the fire extinguisher inspection record and the filling record, and is also used to classify the use priority levels from short to long according to the effective time, respectively high and low;

[0040] The fire information monitoring unit is used to receive flame information, smoke information and fire location information, and determine the current fire hazard level; the fire hazard level is divided into level one, level two and level three according to the flame and smoke from small to large;

[0041] The fire extinguisher dispatch unit is used to determine the fire section according to the fire location information, and control the alarm lights of the fire extinguisher boxes of the corresponding priority level in the fire section to flash according to the fire hazard level, and postpone to the next level if there is no corresponding priority; specifically, when the fire hazard level is level one, the alarm lights of the high-priority fire extinguisher boxes are controlled to flash, when the fire hazard level is level two, the alarm lights of the low-priority fire extinguisher boxes are controlled to flash, and when the fire hazard level is level three, the alarm lights of the high-priority and low-priority fire extinguisher boxes are controlled to flash at the same time;

[0042] According to the different fire danger levels, the alarm lights of the fire extinguisher boxes will flash with different priorities to guide the use of fire extinguishers with different validity periods. When the fire danger level is level one, there is only smoke and no open flames; therefore, the alarm lights of the high-priority fire extinguisher boxes flash to guide the use of fire extinguishers with short validity periods, that is, near-expiry fire extinguishers, thereby reducing the waste of fire extinguisher filling and increasing the utilization rate of fire extinguishers; when the fire danger level is level two, there are obvious sparks, indicating that the fire is developing and measures need to be taken as soon as possible to extinguish the fire. In this case, in order to ensure that the fire can be extinguished quickly and effectively and prevent it from further spreading into a major fire, the alarm lights of the low-priority fire extinguisher boxes start flashing. Guide the priority selection of fire extinguishers with longer validity periods and more stable performance for initial fire extinguishing operations to ensure that the best fire extinguishing effect can be achieved even in the face of small-scale flames that may already exist. Once the fire danger level reaches the highest level three, it means that obvious flames have appeared on the scene and the situation is very critical, and immediate action must be taken to control it. In this emergency situation, in order to maximize the fire-fighting efficiency and prevent the fire from spreading further, the validity period of the fire extinguisher is no longer distinguished. Therefore, it is necessary to obtain as many fire extinguishers as possible to ensure the fire-fighting effect and prevent the fire from spreading.

[0043] Through such a hierarchical response mechanism design, resource utilization can be effectively improved while personnel safety and property protection can be better guaranteed.

[0044] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
