Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a control device for a fire-fighting wall-climbing device based on the Internet of Things and PLC control. Background Technology

[0002] In scenarios such as fire rescue and exterior wall construction in high-rise buildings, load-bearing aerial work platforms are crucial tools for achieving high-altitude operations. However, existing load-bearing aerial work platforms have many limitations in structural design and control methods, making it difficult to meet the needs of efficient and safe operations in complex scenarios. Specific shortcomings are as follows: The signal transmission and control command interaction between the various functional modules of the existing equipment mainly rely on cable connections. This wired connection method results in redundancy and significant drag on the overall structure of the equipment. It not only increases the weight and size of the equipment, making it bulky, but also restricts the flexibility of its movement. During climbing, the equipment is prone to jamming due to cable entanglement and pulling, and may even cause risks such as line wear and signal interruption, seriously affecting the continuity of operations. Moreover, due to the limitations of the wired connection and control range, the existing equipment must maintain a certain safe distance from the wall during operation, and cannot be operated at close range to the wall for precise operation. Especially in special scenarios such as fires, high temperature and dense smoke environments will further accelerate the aging of wired lines and signal interference, causing the equipment to be unable to reach critical operating windows, affecting the effectiveness of rescue or operation.

[0003] Meanwhile, existing equipment is mostly controlled via local wired operation or short-range wireless remote control (such as single Bluetooth or radio frequency signals), lacking global remote control capabilities. On the one hand, the control signal coverage is limited, and when the equipment climbs to a higher height or is blocked by walls or obstacles, signal attenuation or interruption can easily occur, leading to loss of control. On the other hand, it cannot achieve coordinated control of multiple modules. Each module operates independently, making it difficult to dynamically adjust the coordination logic according to real-time working conditions (such as wall flatness and load changes), resulting in limited lifting height and difficulty in accurately reaching the operating window. Utility Model Content

[0004] The purpose of this invention is to overcome the limitations of existing fire-fighting wall-climbing devices, which are restricted by wired connections and control range. Existing devices require a certain safe distance from the wall during operation, making it impossible to get close enough to the wall for precise operation. This results in the device being unable to reach critical operation windows, affecting rescue or operational effectiveness. This invention provides a control device for fire-fighting wall-climbing devices. A single control and communication integrated module is connected to a single motion module of the fire-fighting wall-climbing device via Ethernet, and the control and communication integrated modules are wirelessly connected to each other. This achieves wireless collaborative control of all modules of the fire-fighting wall-climbing device, breaking the limitations of wired connections.

[0005] The objective of this utility model is achieved through the following technical solution: A control device for a fire-fighting wall-climbing device includes a cloud server and several control and communication integrated modules.

The control and communication integrated modules also communicate with each other wirelessly.

[0006] Preferably, the control and communication integration module includes a cloud BOX, a PLC control unit, and a wireless communication unit. The cloud BOX and the wireless communication unit are connected to the PLC control unit. The cloud BOX is also connected to the cloud server via cloud signal transmission communication. The wireless communication unit is connected to the wireless communication units of other control and communication integration modules. The PLC main control and motion module are connected via Ethernet communication.

[0008] Preferably, the control and communication integration modules are also connected wirelessly via methods including WIFI, Bluetooth, 4G, 5G, or radio frequency connection.

[0009] As a preferred embodiment, the control device of the fire-fighting wall-climbing device also includes an intermediate relay, which is located between the power supply and the motion module. The intermediate relay is also connected to the control communication integration module. The cloud server sends control commands to the control communication integration module, and the PLC main control unit controls the on / off state of the intermediate relay to realize the power-off reset of the motion module.

[0018] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0019] Example 1: A control device for a fire-fighting wall-climbing device, such as Figure 1 As shown, it includes a cloud server and two control communication integration modules. The cloud server communicates with each control communication integration module through cloud signal transmission. Each control communication integration module communicates with a single motion module of the fire climbing device through Ethernet. The control communication integration modules also communicate with each other wirelessly.

[0020] The control and communication integration module includes a cloud BOX, a PLC control unit, and a wireless communication unit. The cloud BOX and the wireless communication unit are connected to the PLC control unit. The cloud BOX is also connected to the cloud server via cloud signal transmission. The wireless communication unit is connected to the wireless communication units of other control and communication integration modules. The PLC main control and motion module are connected via Ethernet communication.

[0021] The motion module includes two drivers and two motors, with each driver and motor matched. The driver is equipped with a pulse port and a hard-connect port. The pulse port is used to control the motion accuracy of the motor, and the hard-connect port is used to control the reliability status of the motor.

[0022] The control and communication integration modules can also communicate with each other wirelessly via methods including WIFI, Bluetooth, 4G, 5G or radio frequency connection.

[0023] The control device of the fire-fighting wall-climbing device also includes an intermediate relay E / A. The intermediate relay is located between the power supply and the motion module, and is also connected to the control communication integration module. The cloud server sends control commands to the control communication integration module, and the PLC main control unit controls the on and off of the intermediate relay to realize the power-off reset of the motion module.

[0024] like Figure 2 As shown, the motion module includes an upper locking module 1, a lower locking module 2, and a platform module 4, which are mounted on the ladder body 3. The lower locking module and the platform module are integrated into a single motion module, controlled by a single control and communication integrated module. Optionally, the motion module may also include an intermediate locking module for further control of the fire-fighting climbing device.

[0025] A control method for a fire-fighting wall-climbing device, comprising a control device for the fire-fighting wall-climbing device, including: Step 1: Install the ladder module; Step 2: The cloud server controls the motor of the motion module matched with the locking module through the first communication integration module to complete the installation of the locking module; Step 3: The cloud server controls the motor of the motion module matched with the lower locking module through the control second communication integration module to complete the installation of the lower locking module; Step 4: The cloud server controls the motor of the motion module matched with the platform module by controlling the second communication integration module, thereby completing the installation of the platform module.

[0026] In step 3, the cloud server controls the motor of the motion module matched with the lower locking module by controlling the second communication integration module. Specifically, the cloud server first detects whether there is cloud signal transmission with the first communication integration module. If there is cloud signal transmission, the first and second communication integration modules communicate wirelessly, and the cloud server controls the motor of the motion module matched with the lower locking module through the first and second communication modules. If there is no cloud signal transmission, the cloud server establishes cloud signal transmission with the second communication integration module and directly controls the motor of the motion module matched with the lower locking module by controlling the second communication integration module. In step 4, the cloud server controls the motor of the motion module matched with the platform module by controlling the second communication integration module. Specifically, the cloud server first detects whether there is cloud signal transmission with the first communication integration module. If there is cloud signal transmission, the first and second communication integration modules communicate wirelessly, and the cloud server controls the motor of the motion module matched with the platform module through the first and second communication modules. If there is no cloud signal transmission, the cloud server establishes cloud signal transmission with the second communication integration module and directly controls the motor of the motion module matched with the platform module by controlling the second communication integration module.

[0027] When a power-off reset of the motion module is required, the cloud server sends a power-off reset command to the control communication integration module. The PLC main control unit of the control communication integration module controls the on / off state of the intermediate relay according to the command, thereby cutting off or restoring the connection between the power supply and the motion module through the intermediate relay, thus realizing the power-off reset of the motion module.

[0028] Specifically, in the actual control process of the fire-fighting wall-climbing device, the specific implementation method of the control is as follows: After the ladder module is installed, the cloud server first sends an initialization command to the corresponding motion module through the first communication integration module. After receiving the command, the PLC control unit drives the motors M5-1 and M5-2 (corresponding to the rotary motors of the locking module) of the locking attachment module to rotate 90 degrees in the forward direction, so that the upper claw hook switches from the storage state to the ready-to-mount posture. At the same time, motors M6-1 and M6-2 (claw clamping motors) are at the maximum stroke position, ensuring that the claw opens to the maximum diameter. The operator collects the distance sensor data of the locking attachment module in real time (detecting the vertical distance to the wall). When the cloud server receives the distance value and it is stable within the preset threshold of 30-50mm, it sends a "forward movement command". Motor M1 (upper claw translation motor) runs in the forward direction with the accuracy set by the pulse port (step size 0.1mm), driving the locking attachment module to move horizontally forward along the ladder until the front end of the claw exceeds the edge of the wall by 50mm. At this time, M1 stops and triggers the limit switch. The cloud server records the current position as the "mounting reference point".

[0029] Subsequently, the cloud server sends a "descent command," and motor M2 (the upper claw lifting motor) starts through the hard-connect port, driving the locking attachment module to descend slowly. During the process, the pressure sensor provides real-time feedback on the contact pressure between the hook and the inside of the building. When the pressure value reaches the set threshold of 500N, the PLC control unit immediately cuts off the power to M2 and simultaneously triggers M6-1 and M6-2 to rotate in reverse, contracting to the clamping state through pulse control until the pressure sensor feedback value stabilizes in the 800-1000N range. At this point, M6-1 and M6-2 stop and memorize the current stroke, the locking attachment module is installed, and the cloud server returns a "claw locked" signal to the operator.

[0030] When installing the lower locking module, if the cloud server maintains cloud signal transmission with the first communication integration module (signal strength ≥ -80dBm), the first communication module forwards instructions to the second communication module: the PLC control unit of the second communication module drives the motors M5-3 and M5-4 (lower claw rotary motors) of the lower locking module to rotate synchronously, with the action logic being consistent with the upper locking module; simultaneously, the first and second communication modules exchange relative position data between the two modules in real time via WIFI (error ≤ 2mm) to ensure that the upper and lower claws are in the same vertical plane. If the signal of the first communication module is interrupted (signal strength < -85dBm for 3 seconds), the cloud server immediately switches to the direct connection mode with the second communication module and sends instructions via the 4G network. At this time, the second communication module independently collects the displacement and pressure data of the lower claw, and after completing the installation, directly sends back the "lower claw locked" signal to the cloud server, with synchronization calibrated by the built-in clock.

[0031] During platform module installation, since it shares the second communication integration module with the lower locking module, their actions are linked through the internal logic of the PLC control unit: After the lower claw locks, motors M3-1 and M3-2 (platform flipping motors) rotate 90 degrees forward from the initial 0-degree vertical state, driving the platform module to unfold to a horizontal state. During this process, the tilt sensor monitors the horizontality in real time (deviation ≤ 0.5 degrees). If it exceeds the range, it is finely adjusted by pulse. After the platform is in place, motors M6-3 to M6-6 (platform fixing motors) retract synchronously according to the parameters of memory point B, completing the fixation with the wall. At this time, the cloud server integrates the status data of the upper claw, lower claw, and platform. If all three meet the "locking" condition, the installation stage is determined to be completed, and the system enters the waiting-to-climb-the-wall state.

[0032] During the automatic wall-climbing phase, the cloud server initiates a loop logic based on the preset number of floors: In each loop, the M1 motor rotates from the initial position D to the target position C, triggering a series of actions: lower claw unlocking → upper claw bearing load → lower claw moving forward → lower claw locking → upper claw unlocking → upper claw moving forward. Each action is verified by remote signaling and telemetry data (e.g., whether the motor current is within the rated range, whether the limit switch is triggered). When the number of loops reaches N, all motors trigger the brakes, and the platform module maintains a horizontal bearing state, waiting for rescue operation instructions.

[0033] In case of emergency recovery, after the operator presses the "reset button", the cloud server immediately sends a "power-off reset command". The PLC control unit of the second communication module triggers the intermediate relay KA to close, cutting off the power to the lower claw and platform module for 2 seconds, causing the motor to lose power and release. Then, the unlocking, translation and storage actions are executed in reverse order. Throughout the process, the wireless communication unit prioritizes the 5G network to transmit emergency signals to ensure that the initial state reset is completed within 10 seconds.

[0034] Example 2: A control device and control method for a fire-fighting wall-climbing device are basically the same in principle and implementation as in Example 1, with the following differences: Figures 3-5 As shown, the motion module includes an upper locking module and a lower locking module. The upper locking module is controlled by one control and communication integration module, and the lower locking module is controlled by another control and communication integration module. The main difference between this solution and Embodiment 1 is that the lower locking module and the platform module in Embodiment 1 are integrated into a single lower locking module, which performs the functions of both the lower locking module and the platform module in Embodiment 1.
