Description

Technical Field

[0001] This invention relates to the field of elevator cleaning technology, specifically to a fully automatic intelligent cleaning, disinfection, and safety assurance system and method for elevators. Background Technology

[0002] As an indispensable vertical transportation tool in modern high-rise buildings, the cleanliness of elevators directly affects user experience, public health and safety, and the lifespan of elevator equipment. However, current elevator cleaning mainly relies on manual operation, which has many drawbacks.

[0003] First, manual cleaning is inefficient and costly. The complex structure of elevator cars creates many hard-to-reach areas that are difficult to clean thoroughly by hand, often resulting in omissions. Furthermore, cleaning staff have limited working hours, preventing cleaning during peak hours and forcing cleaning to be done only during off-peak times, further reducing efficiency. In addition, hiring cleaning staff incurs salaries and benefits, increasing operating costs for property management companies.

[0004] Secondly, existing cleaning methods fail to adequately consider potential emergencies that may occur during elevator operation, posing certain safety hazards. During manual cleaning, if the elevator suddenly malfunctions, experiences a fire, or suffers an earthquake, cleaning personnel may be unable to evacuate in time, potentially hindering rescue efforts and threatening their safety. Furthermore, cleaning equipment may also become obstacles in emergencies, affecting the normal operation of the elevator and personnel evacuation.

[0005] Furthermore, the existing cleaning model significantly reduces passenger experience when cleaning elevators during peak hours, and the cleaning work lacks flexibility. Cleaning during peak hours not only occupies the elevator and increases passenger waiting time, but may also cause inconvenience due to the presence of cleaning equipment, affecting passenger travel efficiency and comfort. At the same time, because the cleaning time is fixed, it cannot be flexibly adjusted according to the actual usage of the elevator, meaning that the elevator may not need cleaning at certain times, while at other times it may be unsanitary due to the inability to clean in a timely manner.

[0006] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0007] This invention discloses a fully automatic intelligent cleaning, disinfection and safety assurance system and method for elevators, aiming to solve the problems of low efficiency, high labor costs, safety hazards and poor cleaning flexibility in current elevator cleaning work.

[0008] The technical solution of the present invention is as follows: A fully automated intelligent cleaning, disinfection, and safety assurance system for elevators includes: A multimodal detection module, which includes radar and an AI vision camera, enables environmental perception and status acquisition within the elevator car; The central control module, connected to the detection module, includes a main control board, a car control board, and an IoT communication unit, which realizes data processing, logic control, multi-device collaboration, and command issuance. The intelligent cleaning module, connected to the central control module, includes a cleaning robot, an ultraviolet disinfection unit, an aromatherapy / air purification unit, and a ventilation unit. According to the instructions of the control system, it performs cleaning and sterilization operations inside the elevator car, achieving precise execution of cleaning actions.

[0009] The central control module counts the number of elevator calls every 5 minutes and calculates the passenger flow density using the formula D=N(T) / T. When D<0.6 times / minute, it is determined to be a low peak and a cleaning task is automatically triggered, which is performed once a day.

[0010] The central control module uses a multimodal fusion judgment formula: P=0.6*P1+0.4*P2; cleaning is prohibited when P≥0.6 and allowed when P<0.6, where P1 is the AI ​​visual confidence level and P2 is the radar confidence level.

[0011] A fully automated intelligent cleaning and disinfection safety assurance method for elevators includes the following steps: S1, System Power-On Initialization The system starts up, the intelligent cleaning module completes its self-test, and enters standby mode, awaiting subsequent instructions and scheduling. S2, Module Standby and Command Reception The intelligent cleaning module remains in standby mode, awaiting cleaning / sterilization commands; S3, Automatic Cleaning Command The system automatically triggers cleaning tasks based on peak and off-peak hours of elevator usage. S4, Multimodal Detection Module Startup The environment inside the elevator car is detected by multi-source fusion of radar and AI vision cameras; S5. Detection and judgment of people / living objects in the car. The system uses data from the multimodal detection module to determine whether there are people or living objects inside the elevator car. S6. Start the cleaning process After the cleaning robot enters the elevator car, it performs a complete cleaning and sterilization operation according to the preset steps; S7, Emergency Response When the main control board detects that the elevator has received a special status signal such as a fire alarm or earthquake, it immediately terminates the cleaning command. If the main control board receives a fire alarm or earthquake signal at any moment during the cleaning process, the cleaning operation will be stopped immediately, and the cleaning robot will quickly retreat to a safe corner of the elevator car and wait for the elevator to resume normal operation. S8, Robot self-state verification After the cleaning operation is completed, the system verifies the status of the cleaning robot itself.

[0012] In step S4, the multi-source fusion formula is: P = α·P1 + β·P2; Where P1 is the AI ​​visual confidence level, P2 is the radar confidence level, α=0.6, β=0.4, α+β=1; When P ≥ 0.6, it is determined that there are people or living things, and cleaning is prohibited; If P < 0.6, it is determined that there are no people or living beings, and the startup is allowed.

[0013] In step S5: If the judgment result is "Y", it means that there are people / living objects in the car. At this time, the intelligent cleaning module remains in standby mode, does not perform cleaning tasks, and waits for the next dispatch. If the judgment result is "N", it means that there are no people / living objects in the car. The main control board detects no call command and automatically runs the cleaning robot to enter the floor. When the cleaning robot is detected to have entered the car, the elevator door is automatically closed and the "Elevator cleaning in progress" prompt is displayed.

[0014] In step S6, the cleaning sequence collaborative control algorithm is executed in a fixed order: dust removal → wet wiping / dry wiping → floor cleaning → UV disinfection → forced ventilation → aromatherapy / air purification; Dust removal and cleaning: The cleaning robot extends its brushes to remove dust from the car walls, ceiling, and doors; Wet / dry cleaning: Wet / dry cleaning of the car interior walls, ceiling, and doors; Floor cleaning: Thoroughly clean the car floor; Sterilization and disinfection: Activate the ultraviolet disinfection unit to disinfect the car. The disinfection time for each operation shall not exceed 30 minutes. Ventilation: After cleaning and sterilization, open the elevator door and ventilate through the ventilation unit; Air purification: The cleaning robot activates the aromatherapy / air purification unit to purify the air in the car.

[0015] In step S8: If the verification result is "N", it means there is no abnormality. The cleaning robot leaves the car and returns to the standby area. The elevator resumes normal use, and the cleaning instructions in the monitoring room / cleaning room automatically end. If the verification result is "Y", it means there is an abnormality. After the cleaning robot issues a warning signal and completes local recording, it leaves the car and returns to the standby area. After the abnormality is handled and the elevator resumes normal use, the cleaning instructions from the monitoring room / cleaning room will automatically end.

[0016] Compared to existing technologies, the advantages of this invention are as follows: This invention comprises a multimodal detection module, a central control module, and an intelligent cleaning module, forming a fully automated intelligent cleaning, disinfection, and safety assurance system for elevators, achieving automation and intelligence in elevator cleaning. Specifically, the control system can collect elevator operation data to determine whether the elevator is in off-peak usage, thereby generating cleaning instructions without affecting passenger experience. After the cleaning instruction is generated, the detection module can accurately detect whether there are no people in the elevator car, ensuring that cleaning operations are carried out in a safe and undisturbed environment. When the detection result indicates that there are no people in the car, the control system will activate the intelligent cleaning module to perform the cleaning operation. This design effectively avoids many drawbacks of manual cleaning, such as low efficiency, difficulty in thoroughly cleaning hard-to-reach areas, and high labor costs. Simultaneously, cleaning during off-peak hours significantly improves cleaning efficiency and reduces operating costs. Furthermore, this system avoids the inconvenience caused to passengers by cleaning during peak elevator usage, improving the flexibility and safety of cleaning work. Through automated and intelligent cleaning processes, this invention not only improves cleaning efficiency and quality and reduces operating costs, but more importantly, it has significant and superior technical effects in ensuring personnel safety and enhancing user experience.
