Abstract: This paper mainly explores the methods for predicting the service life of hotel locks based on big data analysis. Taking the experience of Shenzhen Locstar Technology Co., Ltd. (Locstar) in the field of hotel locks as an example, it elaborates on how to utilize big data technology to integrate multiple sources of data on hotel locks, including usage frequency, environmental information, and user operation behaviors, to build a scientific and reasonable prediction model, aiming to achieve accurate prediction of the service life of hotel locks. This not only helps hotels to reasonably plan lock replacement and maintenance strategies, reduce operating costs, but also improves hotel security and customer satisfaction. Meanwhile, it also provides valuable references for the application of big data in product management in the hotel lock industry.
In the hotel industry, hotel locks, as the key equipment for ensuring the security and management of guest rooms, are of vital importance in terms of their reliability and service life. Traditional hotel lock management methods often rely on regular inspections and empirical judgments, making it difficult to accurately predict the remaining service life of locks. This may lead to waste of resources due to premature replacement of locks or potential security risks caused by failure to replace them in a timely manner. With the vigorous development of big data technology, Shenzhen Locstar Technology Co., Ltd. (Locstar), relying on its 26 years of experience in
smart lock manufacturing, has been actively exploring the application of big data analysis in predicting the service life of hotel locks, aiming to provide hotels with smarter and more efficient lock management solutions.
The usage frequency of hotel locks is one of the important factors affecting their service life. The hotel locks produced by Locstar have the function of recording the number of unlocking times. By counting the number of unlocking times of different
hotel room locks within a certain period, we can understand the frequency of their use. For example, the locks in public areas such as hotel lobbies and meeting rooms are usually used more frequently, while the locks in some spare guest rooms are used relatively less frequently. These data can provide a basis for subsequent analysis because high-frequency use will accelerate the wear of the mechanical parts of the locks, such as the lock cylinder and bolt.
The environmental conditions of hotels also have a significant impact on the performance and service life of hotel locks. The hotel locks of Locstar can integrate environmental sensors to collect environmental information such as temperature, humidity, and electromagnetic interference. In hotels in coastal areas, the high humidity and salty air may corrode the metal parts of the locks. In some guest rooms close to large electrical equipment or communication base stations, electromagnetic interference may affect the normal operation of the electronic components of the locks. Long-term monitoring and organization of this environmental data are helpful for analyzing the correlation between environmental factors and the service life of hotel locks.
The operation behaviors of hotel guests vary greatly, which also affects the service life of hotel locks. Hotel locks can record user operation data such as the duration of unlocking and whether there are attempts of forced unlocking. For example, some guests may use excessive force when unlocking or hold the unlocking button for a long time. These improper operations may damage the internal mechanical and electronic structures of the locks. By collecting and analyzing a large amount of user operation data, we can identify the impact of different types of operation behaviors on the service life of hotel locks.
After collecting the original big data on hotel locks, data preprocessing is required first. This includes removing noise and outliers in the data. For example, abnormal unlocking times or extreme environmental data points recorded due to sensor failures or system errors need to be identified and corrected. Meanwhile, for missing data, interpolation methods or model-based filling methods can be used for processing to ensure the integrity and accuracy of the data and provide a reliable data basis for the subsequent model construction.
Extract key features related to the service life of hotel locks from the preprocessed data. For usage frequency data, features such as the average number of unlocking times per day and the unlocking frequency during peak hours can be calculated. For environmental data, features such as the range of temperature changes, the average humidity, and the peak electromagnetic interference intensity can be extracted. For user operation data, features such as the proportion of forced unlocking attempts and the average unlocking time can be calculated. These features will be used as input variables for constructing the prediction model and can more effectively reflect the usage status of hotel locks and potential factors affecting their service life.
Multiple machine learning algorithms can be used to build the service life prediction model for hotel locks. For example, a linear regression model can initially establish a linear relationship between the service life of hotel locks and various features, and the model parameters can be solved by the least squares method. In addition, the decision tree algorithm can classify and perform regression prediction on data according to the values of different features, which has a good effect on dealing with data of hotel locks with multiple discrete and continuous features. Neural network algorithms, such as multi-layer perceptrons, can also be considered. They can automatically learn the complex nonlinear relationships in the data and adjust the connection weights and thresholds of neurons to fit the mapping relationship between the service life of hotel locks and multi-source data. Use a large amount of existing historical data on hotel locks to train the selected model so that the model can learn the patterns and rules in the data and thus be able to predict the service life of new hotel lock data.
Metrics such as mean squared error (MSE), mean absolute error (MAE), and coefficient of determination (R²) are used to evaluate the performance of the service life prediction model for hotel locks. MSE measures the average squared error between the predicted value and the actual value, reflecting the dispersion degree of the predicted value. MAE represents the average absolute error between the predicted value and the actual value, which more intuitively reflects the size of the prediction error. R² evaluates the fitting degree of the model to the data. The closer R² is to 1, the better the fitting effect of the model. Through the calculation and analysis of these evaluation metrics, we can judge the quality of the prediction model and further optimize and adjust the model.
If the model evaluation results are not satisfactory, multiple optimization strategies can be adopted. For example, increase the amount of data, collect more actual usage data of hotel locks to enrich the learning samples of the model and improve the generalization ability of the model. Adjust the hyperparameters of the model, such as the number of layers, the number of nodes, and the learning rate in the neural network, or the tree depth and the selection criteria for splitting nodes in the decision tree. Use cross-validation and other methods to find the optimal combination of hyperparameters. Ensemble learning methods, such as random forest, can also be used to combine multiple decision tree models and obtain the final prediction result through voting or averaging, improving the accuracy and stability of the model.
Based on the predicted service life of hotel locks by big data, hotels can implement preventive maintenance strategies. When it is predicted that the lock of a certain guest room is approaching the end of its service life, hotel managers can arrange maintenance personnel in advance to inspect, maintain, or replace key components of the lock, such as replacing the worn lock cylinder in advance, to avoid lock failures during guests' stays, ensuring the normal operation of the hotel and the safety and convenience of guests.
Hotels can reasonably optimize resource allocation according to the predicted service life of hotel locks. For locks with high usage frequency and a relatively short expected service life, maintenance resources and spare locks can be prioritized. Meanwhile, when hotels are undergoing decoration or upgrades, they can make targeted lock replacement plans according to the remaining service life of locks in different areas, avoiding unnecessary large-scale replacements and reducing operating costs.
By realizing precise maintenance and management of hotel locks through big data prediction, customer satisfaction can be effectively improved. Guests will not encounter inconveniences due to lock failures during their stays, such as being unable to unlock the door normally or the door being locked. Hotels can also provide personalized services for guests based on the usage data of locks. For example, for guests who often forget to bring their room cards, convenient alternative solutions such as unlocking with mobile phones can be provided to enhance guests' stay experience.
In conclusion, the prediction of the service life of hotel locks based on big data analysis has important theoretical and practical significance. Through the exploration and practice of Shenzhen Locstar Technology Co., Ltd. in the field of hotel locks, we have seen the great potential of big data technology in integrating multiple sources of data on hotel locks, building prediction models, and optimizing lock management. However, there are still some challenges at present, such as data security and privacy protection issues, and data compatibility issues among different hotel brands and management systems. In the future, with the continuous progress of technology, it is expected to further improve the application of big data in predicting the service life of hotel locks, achieve more accurate and efficient hotel lock management, provide strong support for the intelligent development of the hotel industry, and also provide useful reference experiences for product management in other similar industries.
