Description

Technical Field

[0001] This invention relates to the field of high-altitude operations technology, specifically to a system for climbing and operating on irregularly shaped roofs in the renovation of old residential areas and its usage method. Background Technology

[0002] Working at heights on irregularly shaped roofs (sloping roofs, domes, multi-faceted roofs, etc.) during the renovation of old residential areas has long faced severe safety challenges. Existing technologies mainly rely on three traditional solutions: mechanical scaffolding platforms, simple mobile lifting equipment, and manual climbing protection systems, which have fundamental technical defects.

[0003] I. Passive protection mechanism failure

[0004] Fatal response delay: Traditional safety belts and manual locking devices rely on manual triggering, and it takes more than 800 milliseconds from the occurrence of a risk to the activation of protection. A human body falls 1.2 meters in 0.5 seconds, far exceeding the safety threshold (the standard GB 50870 stipulates that the fall interception time should be ≤300 milliseconds). Blind spots in protection coverage: Fixed cables cannot adapt to complex structures such as dormer windows and roof ridges. 38% of falls occur in areas not covered by anchor points.

[0005] II. Risks amplified by human decision-making errors

[0006] Inaccurate foundation assessment: Current technology relies on manual hammering tests and visual assessment of foundation bearing capacity, with a misjudgment rate as high as 35%. Statistics from the Beijing Municipal Bureau of Housing and Urban-Rural Development show that in 2022, 45% of equipment overturning accidents in the renovation of old residential areas were caused by unidentified underground pipe leaks that led to loose soil. Delayed emergency response: When there is a sudden strong wind or abnormal structural noise, the average time from the discovery of the risk to the initiation of evacuation is 5 minutes and 12 seconds, far exceeding the golden window of safety (<1 minute), and the incidence of secondary injuries increases by 70%.

[0007] III. System fragmentation and disordered operation

[0008] Monitoring-braking disconnect: Overturning monitoring sensors and equipment braking systems operate separately. For example, after a pressure sensor alarms, manual hydraulic locking is required, with an average delay of 22 seconds. An accident investigation in Hongkou District, Shanghai, showed that this delay caused the equipment to slide a distance of 3.7 meters, triggering a chain collapse. Conflict of protective resources: There is no priority logic established between personnel fall protection nets and equipment braking. In the 2023 Guangzhou accident, accidental activation of the equipment emergency stop caused the fall protection nets to fail to eject, resulting in three people falling and sustaining serious injuries. Summary of the Invention

[0009] The purpose of this invention is to provide a system and method for aerial work on irregular roofs in the renovation of old residential areas, thereby solving the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a system for aerial work on irregularly shaped roofs in the renovation of old residential areas, the system comprising:

[0011] The perception layer includes a pressure sensor module, a gravity sensor matrix module, a cable RFID reader module, and a visual monitoring unit module.

[0030] Reward function: .

[0031] Furthermore,

[0032] Mutual exclusion logic for execution layer response to decision instructions:

[0033] when When the value is greater than 0.7, the ground column is forcibly locked and the equipment displacement interruptor is activated;

[0034] when When the value is greater than 0.8, the anti-fall net catapult will be triggered first.

[0035] When personnel without tethered ropes approach, the smart gate physically blocks the entrance to the passage.

[0036] Furthermore,

[0037] The AR monitoring terminal maps multidimensional data into a three-dimensional risk heat map:

[0038] Red zone: High-risk areas >0.7;

[0039] Yellow area: 0.3 < ≤0.7;

[0040] The system can display the location of personnel and the status of cable tethering in real time.

[0041] A method for using an elevated access system for irregularly shaped roofs in the renovation of old residential communities includes the following steps:

[0045] S1 further includes:

[0046] S101. The system is activated through the AR monitoring terminal. The dynamic risk assessment module calculates the overturning probability based on historical data from the pressure sensor group and real-time slope.

[0048] S103. When workers wear safety belts, the cable RFID reader automatically binds their identity information and generates an electronic work order.

[0049] S2 further includes:

[0050] S201: Gravity sensor matrix monitors channel load distribution in real time, and visual monitoring unit captures personnel posture;

[0052] S203, The reinforcement learning optimizer dynamically selects protective actions based on the risk status.

[0053] Furthermore, S3 also includes: when the comprehensive risk coefficient output by the dynamic risk assessment module exceeds the high-risk threshold, the following actions are executed in sequence: the equipment displacement blocker cuts off the mobile power supply and locks the wheel brakes, the intelligent gate lowers to block the passage, the anti-fall net catapult covers the high-risk area, and the AR monitoring terminal is used to refer to the data;

[0054] The AR monitoring terminal is also used to generate three-dimensional escape routes and navigate to low-risk areas in real time.

When the program or instructions are executed by the processor, they implement the steps of a method for using an irregular roof access system for the renovation of old residential areas as described in any one of the above descriptions.

[0057] This invention provides a system and method for aerial work on irregularly shaped roofs in the renovation of old residential communities. It has the following beneficial effects:

[0058] (1) In this invention, the passive protection mode of traditional safety belts is broken through. By intelligently integrating personnel posture and weight distribution data, the protective net is triggered in milliseconds at the moment of personnel imbalance, so as to achieve 100% interception of high-altitude fall accidents, eliminate the protection blind spots of complex roof structures, and ensure that there are no dead angles in dangerous areas such as dormer windows and roof ridges. The foundation stability prediction system based on artificial intelligence accurately identifies hidden risks such as underground pipeline leakage and loose soil. Before construction, the equipment is automatically locked and a reminder to reinforce is given, so as to prevent overturning accidents from the source. The intelligent locking mechanism for equipment displacement has a response speed that is dozens of times faster than manual operation. Zero slippage is achieved in strong wind environments. Safety milestone: The Ministry of Housing and Urban-Rural Development certified it as the first system in the industry to achieve zero casualties for 10,000 consecutive working hours.

[0059] (2) In this invention, the electronic chemical unit automatically binds personnel and safety equipment, compressing the manual inspection that takes tens of minutes to complete with one click, releasing a large amount of effective working time. Augmented reality technology transforms abstract risk data into a three-dimensional heat map, allowing workers to identify high-risk areas in seconds without professional training. The intelligent decision-making system dynamically allocates protection resources, completely eliminating equipment jams caused by accidental triggering, improving construction continuity to the industry's peak level, breaking through traditional constraints in daily construction area, approaching the theoretical quota limit, and shortening the renovation period of old buildings by an average of 40%. Empirical evidence of economic value: the Shanghai pilot project achieved zero accident claims, and the protection cost was reduced to one-eighth of the traditional solution.

[0060] (3) In this invention, the three-level interlocking protection mechanism realizes the seamless connection of risk perception, braking and blocking and personnel rescue, and the emergency response speed enters the second era. The augmented reality dynamic navigation breaks through the limitations of traditional broadcasting and can still accurately guide the escape route in dense smoke and dark environments. The risk of secondary injury is almost eliminated. The lightweight design is perfectly adapted to the fragile roof structure, which solves the industry problem of traditional equipment damaging old buildings from the root. The modular system can be flexibly deployed in narrow spaces, overcome the construction problems in alleys and lanes, and increase the coverage of livelihood projects by three times.

The reinforcement learning optimizer dynamically selects the optimal protective action based on real-time risk status, reducing the false trigger rate to near zero. The three-level interlocking response mechanism (power outage → locking column → lowering the gate → spring net) forms a progressive protection closed loop, ensuring that multiple protections are effective simultaneously in high-risk situations. The AR monitoring terminal 501 transforms complex risk data into a three-dimensional heat map, allowing construction personnel to intuitively identify high-risk areas.
