It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application.

Referring to fig. 1, a schematic flow chart of a crown block control method provided in an embodiment of the present application may specifically include:

s110, acquiring real-time speed information of a motor corresponding encoder of a key component, wherein the key component comprises a cart, a main lifting device, an auxiliary lifting device, a main cart and an auxiliary cart;

illustratively, real-time speed data is collected from motor encoders of critical components. These key components include cart, main hoist, auxiliary hoist, main trolley and auxiliary trolley. A motor encoder is a device that is capable of measuring and providing accurate information of the motor speed. Fig. 2 shows a schematic diagram of a crown block device, which comprises a trolley mechanism running wheel 101, a secondary trolley mechanism 102, a main trolley mechanism 103, a main hoisting mechanism wire rope roller 104, a secondary hoisting mechanism wire rope roller 105 and a main trolley mechanism running rail 106.

S120, determining real-time position information based on the real-time speed information;

illustratively, real-time location information is determined based on real-time velocity information, at which stage the system uses the collected velocity information to calculate the real-time location of each critical component. This may involve combining velocity data with time data to estimate the distance traveled and thus derive location information.

S130, determining distance information between the dangerous area and the real-time position information;

illustratively, the distance between the critical component and the predefined "hazardous area" is determined using the positional information obtained in the previous step. The dangerous area refers to an area which is not accessible to operators of equipment or other mechanical equipment so as to prevent collision or other safety accidents.

And S140, controlling the operation speed of the key components based on the distance information, and generating an alarm prompt instruction.

Illustratively, the operating speed of the critical component is controlled based on the distance information calculated in the previous step. If the critical component is near a dangerous area, the system may slow or stop its motion and may issue an alarm to prevent a potential safety hazard.

In summary, the crown block control method provided by the embodiment of the application can effectively prevent collision and other safety accidents by monitoring the speed and the position of the key components in real time and comparing the data with the predefined dangerous area, thereby providing higher-level safety guarantee for operators and equipment. The operating conditions of the device can be continuously monitored and data recorded, which is useful for post-analysis, fault diagnosis and performance assessment.

In some examples, the above method further comprises:

By way of example, the cumulative travel refers to the total distance the component moves over a period of time. The speed is integrated in the time dimension to yield the total travel distance. The collected accumulated travel data is used to estimate the service life of each critical component.

According to the scheme, through monitoring and analyzing the accumulated travel and the expected service life of the key parts of the crown block, a comprehensive and efficient solution is provided for equipment management, so that the operation safety of the equipment is improved, and the overall maintenance and management efficiency is effectively improved.

In some examples, controlling the operation speed of the key component based on the distance information, and generating an alarm prompt instruction includes:

The distance between the crown block and the dangerous area is smaller than the first preset distance and larger than the second preset distance. In this case, the system will control the speed of operation of the critical components to be less than the first preset speed. This is a precaution aimed at reducing the speed at which the component approaches the hazard area, thereby increasing the response time and reducing the likelihood of collisions. At the same time, the system generates a first alarm prompting instruction. This alarm cue may be a visual or audible signal that alerts an operator or an automated system that a critical component is approaching a hazardous area, requiring attention or action.

Illustratively, when the distance of the key member from the hazardous area is less than or equal to the second predetermined distance. In this case, the system will take more stringent control measures, i.e. lock the critical components from continuing to move towards the hazardous area. Such locking may mean completely stopping the movement of the component to prevent an impending collision or other type of safety incident. At the same time, the system generates a second alarm command. This alarm is typically more urgent or obvious than the first alarm because it indicates that the critical component is in close proximity to the hazardous area and immediate action is required.

Different levels of early warning and control measures are utilized to protect the safety of equipment and operators. The solution in the above embodiment is an early warning that is triggered when the component is close to the hazard area but there is sufficient reaction time. The method corresponding to this embodiment is an emergency response that is triggered when the component reaches or is about to enter a hazardous area, requiring immediate action to prevent an accident.

In some examples, the above method further comprises:

Illustratively, when the key element is in an operational state (e.g., moving or performing a particular operation), but the distance information from the hazardous area is unchanged. There may be some abnormal condition such as a component getting stuck, getting trapped, or the distance monitoring system may fail. In this case, the system will generate a third alarm instruction as a response to this abnormal condition. This alarm is intended to alert an operator or an automated system to check for possible problems, such as whether an obstacle has impeded normal movement of the component, or whether there is a device failure.

The system can also acquire heat radiation distribution information of the surrounding environment of the crown block or the crane. To using thermal imaging techniques to detect temperature distribution in different areas of an environment and identify overheated areas. By analyzing the thermal radiation distribution information, the system can identify the locations of the critical fixtures in the environment. Based on this information, the system can adjust the operating speed of the critical components to prevent collisions with critical equipment. The system reduces the speed of movement of the components or takes other precautions to reduce risk.

The embodiment of the application provides a comprehensive safety monitoring method which not only focuses on the running condition of equipment, but also monitors the surrounding environment. In this way, it is possible to more fully identify potential risk factors and take appropriate precautions to significantly increase the safety level of the entire work area. This approach is particularly valuable for those locations where heavy machinery is operated in complex or high risk environments, and can effectively reduce incidents and malfunctions.

In some examples, controlling the operation speed of the key component based on the heat radiation distribution information includes:

Illustratively, FIG. 3 is a thermal can region diagram. Comprises a crown block body 201, a large vehicle running track 202, a hot-closed tank 203, a first safety area 204 and a second safety area 205. The specific location of the thermal cup is determined using the thermal radiation distribution information. Because the thermal vats contain or process high temperature materials, they typically exhibit high temperature regions on thermal imaging or thermal radiation detection equipment. According to the position information of the thermal-closure tank, the relative position and distance between the crown block or other mechanical equipment and the thermal-closure tank can be judged. The system adjusts the operating speed of the critical components accordingly to ensure safety. When the vehicle approaches the hot pot, the system automatically slows down to reduce the risk of collision and allow it to operate in a safe area.

In summary, the purpose of this application is to statistics and real-time position automatic display function to the historical stroke of each mechanism operation of overhead traveling crane, through the stroke measurement and calculation function, can be when overhead traveling crane operation or stop, show current functioning speed, real-time position and accumulated stroke, through data statistics, analysis, grasp the life and the state condition of each mechanism wheel of overhead traveling crane, discover in advance, solve problem or periodic replacement, the effectual reduction gear that has avoided causing because of the sudden failure of wheel, motor, converter and electrical equipment's damage, guaranteed overhead traveling crane system's steady operation. Meanwhile, the vehicle enters a dangerous area to actively decelerate, alarm or avoid emergency, so as to avoid the occurrence of collision accidents.

The working principle of the device is that when a bus driver operates a master handle of each mechanism, the frequency converter outputs the current speed to control the motor to operate, meanwhile, the encoder at the tail of the motor feeds back the actual speed to the frequency converter, the encoder communicates with the frequency converter through the PLC, the instantaneous actual speed fed back by the encoder is read, the data such as the instantaneous speed, the accumulated stroke, the real-time position and the like of each mechanism are displayed through programming, and the data are displayed through an industrial personal computer picture. And meanwhile, comparing preset coordinates, and actively decelerating or avoiding when entering a dangerous area.

Meanwhile, the actual speed and the actual position are displayed through travel measuring and calculating positioning, the operation of the motor is controlled in an interlocking mode, audible and visual alarm reminding is achieved, the running speed of the crown block in a dangerous area and the passing range of the trolley mechanism are limited, accidents are effectively avoided, and the stable operation of the crown block system is guaranteed.
