Description

Technical Field

[0001] Several embodiments in this specification relate to the field of fire protection teaching equipment technology, specifically to the optimization of the integration and manufacturing cost of fireproof roller shutter training devices. Background Technology

[0002] The fire-resistant roller shutter linkage system, as a core subsystem of the building fire protection system, consists of the fire-resistant roller shutter body, control module, detector group, and linkage control logic. Through multi-level signal triggering from smoke detectors, heat detectors, and other sensors, it achieves the crucial functions of isolating the fire source and blocking the spread of smoke in the early stages of a fire. It is widely used in civil buildings such as industrial plants and commercial complexes. In the fire protection talent training system, the operation and maintenance of this system is listed as a core module of the practical training courses in fire protection companies and vocational schools. Trainees are required to master multiple practical skills, and their operational proficiency directly affects the effectiveness of emergency response in a fire.

[0003] Current fire safety skills training primarily employs a hybrid model of "theoretical instruction + equipment demonstration." It mainly uses 3D animation to demonstrate the sequential logic of roller shutter door linkages, and some institutions also introduce virtual simulation systems to simulate the impact of dense smoke and heat radiation on the opening and closing of roller shutter doors. The practical training relies on a 1:1 industrial-grade training platform, allowing trainees to perform basic operations such as manual rapid deployment and mid-position hold.

[0004] However, while animation demonstrations and virtual simulation technologies can visualize the spread of fire, the operational feedback is limited to the visual level and lacks the tactile training dimension of physical control boxes, making it impossible for trainees to form a coordinated "hand-brain-eye" operational memory. Industrial-grade training equipment, which includes necessary components such as steel guide rails and counterweight boxes, often occupies more than 2 cubic meters of space, resulting in an average equipment occupancy rate of less than 15% per person in the unit's training venue, making it difficult to support group cyclical training.

[0009] As a preferred embodiment, the slide is inclined relative to the front of the housing, and the distance between the end of the slide near the drive motor and the front of the housing is greater than the distance between the end of the slide away from the drive motor and the front of the housing.

[0010] As a preferred embodiment, the side plate is provided with an elastic element at the end away from the drive motor, which connects to the counterweight rod and provides a tendency force for the roller shutter to unfold.

[0011] As a preferred embodiment, the gantry structure is made of a transparent material.

The half-drop relay includes a first contact group and a second contact group. The common terminal and normally closed terminal of the first contact group are respectively connected to the negative terminal of the DC power supply and the half-drop control terminal of the controller.

[0015] Secondly, the embodiments of this specification provide a fire-resistant roller shutter linkage system, including an external fire control device, a smoke detector and a heat detector connected to the external fire control device, and the fire-resistant roller shutter training device described in the first aspect above.

[0016] The beneficial effects of the technical solutions provided in some embodiments of this specification include at least the following: 1. Trainees can manually control the miniature roller shutter door using the buttons in the independent operation button area, meeting their training needs for manual control of the roller shutter door. The wiring terminal area extends the controller's second input terminal to the front of the housing, allowing trainees to repeatedly perform operations such as wiring connections and testing between the fireproof roller shutter training device and external fire control devices, mastering the wiring standards between the training device and the industrial fire protection system. Through the synergy of the "manual control - linkage wiring" dual modules, it covers the key skill assessment points for fire protection facility operators regarding the manual operation of fireproof roller shutter doors, system wiring, and linkage debugging, solving the problem of traditional large equipment's inability to conduct high-frequency disassembly and assembly training, significantly reducing practical teaching costs and safety risks.

[0017] 2. To adapt to diverse training environments such as laboratories or classrooms, the device has undergone meticulous optimization in its mechanical structure design. Adopting a lightweight design concept, it integrates the miniature roller shutter door with the controller that raises and lowers the door, resulting in a more integrated training device with a smaller footprint and improved ease of use. The panel layout is compact, separating the operation area from the observation area, supporting simultaneous observation and rotation of multiple students, meeting the needs of high-density teaching scenarios.

[0018] 3. The lifting direction of the miniature roller shutter door is parallel to the front of the housing, further reducing space occupation and improving the flexibility and convenience of the training device.

[0019] 4. Without adding any extra structure, only by adjusting the way the slide is opened, the training device can achieve two usage modes: hanging and flat, where the weight of the counterweight rod ensures that the roller shutter hangs down and flat naturally. Attached Figure Description

[0027] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings.

[0028] The terms "first," "second," "third," etc., in the description, claims, and accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0029] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this specification. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0030] The core entry qualification for fire protection industry certifications is the Fire Protection Facility Operator (Junior / Intermediate / Advanced) certificate, covering areas such as monitoring and maintenance. Senior positions and technical consulting require a Registered Fire Engineer certificate. Holding a certificate is a mandatory industry requirement, necessitating systematic training to master equipment operation, maintenance, and emergency response capabilities. Both the Fire Protection Facility Operator and Registered Fire Engineer certificates require assessment in fire-resistant roller shutter operation.

[0031] Developing miniaturized fire-resistant roller shutter training devices is an inevitable direction driven by industry standard upgrades, technological miniaturization breakthroughs, and industry-education policy guidance. It aims to address the pain points of traditional training—high cost, low frequency, and high risk—and build a standardized, widely accessible fire-fighting skills training system. Therefore, this solution is proposed.

[0032] Reference Figure 1 As shown, a fireproof roller shutter training device includes a housing 1, a miniature roller shutter door 2 disposed on the front of the housing 1, and a controller disposed inside the housing 1 to control the raising and lowering of the miniature roller shutter door 2. The front of the housing 1 is also provided with a button area 3 that is connected to the first input terminal of the controller to realize manual control of the lifting and lowering of the miniature roller shutter door 2, and a wiring terminal area 4 that is connected to the second input terminal of the controller and can be connected to an external fire control device to realize automatic control of the lifting and lowering of the miniature roller shutter door 2. The wiring terminal area 4 includes multiple second control signal transceiver terminals that correspond one-to-one with multiple first control signal transceiver terminals of the external fire control device.

[0033] Explanatoryly, trainees can manually control the miniature roller shutter door 2 using the buttons in the independent operation button area 3, meeting their training needs for manual control of the roller shutter door. The wiring terminal area 4 extends the controller's second input terminal to the front of the housing 1, allowing trainees to repeatedly perform operations such as wiring connections and testing between the fireproof roller shutter training device and external fire control devices, mastering the wiring standards between the training device and the industrial fire protection system. Integrating the miniature roller shutter door 2 with the controller that controls its raising and lowering results in a significantly smaller roller shutter 22 compared to traditional large industrial-grade fire-fighting linkage equipment. This change not only reduces the device's space occupation, making it easier to place in various training locations, but also reduces the overall weight of the device, alleviating the operational burden.

[0034] Explanatoryly, the advantage of this training device lies in its low-cost simulated rolling shutter door and the terminal block area 4 that can be connected to real external fire control devices. This allows the training device to overcome the limitations of traditional simple simulations, providing trainees with a highly realistic and complex fire linkage operation experience in simulated real fire scenarios. Through hands-on operation of this device, trainees can gain a deeper understanding and mastery of how fire-resistant rolling shutters respond accurately to different fire stages and signals in real fire scenarios, thereby effectively improving their ability to cope with actual fire situations.

[0035] For example, the controller consists of a button board connected to the button area 3, a control board integrating an STC12C5A32S2 chip and power circuit, and a main board for integrating the miniature roller shutter door 2, the button area 3, and the terminal block area 4. The main board can be directly used as the front of the housing 1.

[0036] This lightweight design allows the miniaturized fire-resistant roller shutter training device to be easily deployed and used in various practical scenarios. Trainees can operate and adjust the device more conveniently, thus enabling more efficient training and practice in fire-resistant roller shutter skills. Whether in daily teaching demonstrations or actual operation exercises, the lightweight structure provides great convenience for training activities, helping to improve training effectiveness and quality.

[0037] In one embodiment of this specification, in conjunction with the appendix Figure 2 The back of the housing 1 is provided with a hanging hole for suspending and fixing the training device; The miniature roller shutter door 2 includes a drive motor 21 fixedly mounted on the front of the housing 1, a roller shutter 22 connected to the output shaft of the drive motor 21 at one end, and a counterweight rod 23 connected to the other end of the roller shutter 22. The roller shutter 22 performs a winding motion and an unfolding motion respectively in the forward and reverse rotation of the output shaft of the drive motor 21.

[0038] Explanatoryly, the weight of the counterweight 23 ensures that the roller shutter 22 hangs down and flattens naturally. The drive motor 21 uses forward and reverse control logic to control the raising and lowering of the roller shutter 22, simulating the raising and lowering trajectory of a real roller shutter door. The miniature roller shutter door 2 can be directly hung on the wall or teaching display stand to achieve multi-angle visualization and allow more students to observe and learn. The raising and lowering direction of the miniature roller shutter door 2 is parallel to the front of the shell 1, further reducing space occupation and improving the flexibility and convenience of the training device.

[0039] In illustrative terms, the miniature roller shutter door 2 has a simple structure. The roller shutter 22 can achieve a simulated effect using flexible fabric, significantly reducing manufacturing costs and easily meeting the needs of numerous training devices in teaching scenarios. The output shaft of the drive motor 21 is appropriately extended to accommodate the winding and fixing of the roller shutter 22. The counterweight rod 23 is preferably made of a metal material with a high specific gravity, which can generate a large amount of gravity within a relatively small volume. The winding motion corresponds to the roller shutter 22 rising, and the unfolding motion corresponds to the roller shutter 22 falling.

[0040] In one embodiment of this specification, the miniature roller shutter door 2 further includes a door frame structure arranged parallel to the front of the housing 1. The door frame structure includes two side plates 24 that are perpendicular to the front of the housing 1 and arranged parallel to each other, and the drive motor 21 is located at the top of the side plate 24. The length of the counterweight rod 23 is greater than the distance between the two side plates 24, and both side plates 24 are provided with a sliding groove 241 for the counterweight rod 23 to slide.

[0041] Explained, under the influence of gravity, the counterweight 23 causes the roller blind 22 to hang down and flatten naturally. The drive motor 21 uses forward and reverse control logic to control the raising and lowering of the roller blind 22. During this process, the counterweight 23 moves in the slide groove 241 of the side plate 24 as the roller blind 22 rises and falls, thereby preventing the roller blind 22 from swinging back and forth during the raising and lowering process.

[0042] In one embodiment of this specification, in conjunction with the appendix Figure 3 The slide 241 is inclined relative to the front of the housing 1, and the distance between the end of the slide 241 near the drive motor 21 and the front of the housing 1 is greater than the distance between the end of the slide 241 away from the drive motor 21 and the front of the housing 1.

[0043] Explained, by adopting the above technical solution, the training device can be used flat on a table. At this time, because the slide 241 is inclined at a certain slope relative to the front of the housing 1, the counterweight 23 can still maintain the effect of the roller shutter 22 being flat under the action of gravity. Thus, without adding any additional structure, only by adjusting the opening method of the slide 241, both the suspended and flat usage modes of the training device can be achieved.

[0044] In one embodiment of this specification, the gantry structure is made of a transparent material.

[0045] For example, if an acrylic transparent panel is used, it is convenient for multiple students to watch and learn simultaneously, and the rising and falling process of the roller shutter 22 can be clearly observed from different directions on the front of the housing 1.

[0046] In one embodiment of this specification, the second input terminal of the controller includes a half-drop control terminal and a full-drop control terminal; The fireproof roller shutter training device also includes a half-drop relay installed between the half-drop control terminal of the controller and the terminal block area 4, and a full-drop relay installed between the full-drop control terminal of the controller and the terminal block area 4. Terminal block 4 includes a grounding terminal for connection to an external fire control device, a smoke detection input terminal, a half-drop feedback control terminal pair, a heat detection input terminal, a full-drop feedback control terminal pair, and positive and negative terminals for DC power supply. The half-drop relay includes a first contact group and a second contact group. The common terminal and normally closed terminal of the first contact group are respectively connected to the negative terminal of the DC power supply and the half-drop control terminal of the controller. The common terminal and normally closed terminal of the second contact group are respectively connected to the half-drop feedback control terminal pair. The positive terminal of the half-drop relay is connected to the smoke detection action input terminal and the negative terminal is connected to the ground terminal to control the connection state of the corresponding common terminal of the first contact group and the second contact group. The full-drop relay includes a third contact group and a fourth contact group. The common terminal and normally closed terminal of the third contact group are connected to the negative terminal of the DC power supply and the full-drop control terminal of the controller, respectively. The common terminal and normally closed terminal of the fourth contact group are connected to the full-drop feedback control terminal pair, respectively. The positive terminal of the full-drop relay is connected to the temperature sensing action input terminal, and the negative terminal is connected to the ground terminal to control the connection status of the corresponding common terminal of the third contact group and the fourth contact group.

[0047] Explanatoryly, "half-lower" typically refers to the roller shutter 22 lowering to one-third of its height or to half its height, facilitating personnel evacuation. "Full-lower" means the roller shutter 22 has lowered to its lowest point. This describes the operational steps of the roller shutter door in a real fire isolation scenario: after the smoke detector is triggered, the roller shutter door lowers halfway, blocking the flow of dense smoke from higher locations and leaving a passage for personnel evacuation; after the heat detector is triggered, it lowers fully, forming a physical isolation zone and completely isolating the fire source from the dense smoke. In a DC power supply, the positive terminal is the DC voltage connected to the circuit, and the negative terminal is grounded. The connection status of the common terminal refers to whether it is connected to a normally open or normally closed terminal. Normally open terminals are always left floating by default.

[0048] Explained, the smoke detection input terminal and grounding terminal in terminal block 4 are a set of input terminals for the half-drop relay. When the external fire control device receives a smoke detection action, it outputs DC24V to the half-drop relay, causing the half-drop relay to activate. The common terminal of both the first and second contact groups is disconnected from the normally closed terminal. The half-drop control terminal of the controller changes from being connected to the negative terminal of the DC power supply to being in a floating state, that is, from having no voltage input to a high-level state, which serves as a control signal to control the half-drop of the roller shutter door. At the same time, the half-drop feedback control terminal disconnects and uses this as a feedback signal for the half-drop of the roller shutter door to be fed back to the external fire control device.

[0049] Explained, the temperature-sensing action input terminal and grounding terminal in terminal block 4 are a set of input terminals for the full-drop relay. When the external fire control device receives the temperature-sensing action, it outputs DC24V to the full-drop relay, causing the full-drop relay to activate. The common terminals of the third and fourth contact groups are both disconnected from the normally closed terminals. The full-drop control terminal of the controller changes from being connected to the negative terminal of the DC power supply to being in a floating state, that is, from having no voltage input to a high-level state, which serves as a control signal to control the full drop of the roller shutter door. At the same time, the full-drop feedback control terminal disconnects and uses this as a feedback signal for the full drop of the roller shutter door to be fed back to the external fire control device.

[0050] In one embodiment of this specification, the button area 3 includes an up button, a down button, a stop button, and a reset button.

[0051] Explanatoryly, the four buttons can control the small roller shutter door to rise, fall, stop, and reset respectively. The reset button makes it easy to raise the roller shutter door to the highest position during practical operation, which is suitable for repeated operation in multi-person practical training.

[0052] In one embodiment of this specification, the button control area further includes a plurality of status indicator lights 31 corresponding to the up button, down button, stop button and reset button respectively; The miniature roller shutter door 2 is equipped with a half-lower indicator light 26 and a full-lower indicator light 27.

[0053] Explanatoryly, the half-lowering indicator 26 and the full-lowering indicator 27 are positioned to correspond to the half-lowering stop position and the full-lowering stop position of the roller shutter 22, so as to better observe the status of the miniature roller shutter door 2.

[0054] Example 2 like Figure 4 As shown, a fireproof roller shutter training device differs from Embodiment 1 in that: an elastic element 25 is provided at the end of the side plate 24 away from the drive motor 21, which connects to the counterweight rod 23 and provides a tendency force for the roller shutter 22 to unfold.

[0055] Explanatoryly, based on the traction of the roller blind 22 by the weight of the counterweight rod 23, the roller blind 22 is further guided in the unfolding direction by adding elastic elements 25 such as springs and elastic ropes to achieve flatness, thereby avoiding the problem that the roller blind 22 cannot be kept in a flat state when placed flat or tilted.

[0056] Example 3 Fire-resistant roller shutter linkage system is an important component of fire linkage system. It is widely used in industrial and civil buildings and is also a key practical skill that fire protection companies, fire training institutions and vocational schools focus on training when cultivating fire protection talents.

[0057] See Figure 5 A fire-resistant roller shutter linkage system includes an external fire control device, a smoke detector and a heat detector connected to the external fire control device, and a fire-resistant roller shutter training device as described in the above embodiments.

[0058] For example, the external fire control device is the commonly used GST-LD-8303 module.

[0059] For illustrative purposes, fire-fighting roller shutter linkage systems may also include fire alarm controllers and isolators. Figure 5 The terminals located on the bottom right side of the center are 24VCC, 24GND, Middle, Common, Lower, Common, Smoke Detector Input, Ground, Heat Detector Input, and Ground. These are the second control signal transceiver terminals in terminal block area 4 of the fireproof roller shutter training device. The terminals I1, G, I2, G, COM1, NO1, V+, G, COM2, NO2, D1, D2, Z1, and Z2 in the GST-LD-8303 module are the first control signal transceiver terminals of the external fire control device. The Middle and Common terminals in the second control signal transceiver are the half-drop feedback control terminal pair, and the Lower and Common terminals are the full-drop feedback control terminal pair.

[0060] Working principle: When an external fire control device receives a fire alarm signal, whether it is a smoke detection signal or a temperature detection signal, it can respond quickly. For a smoke detection signal, the system will immediately issue an instruction according to preset logic to control the rolling shutter door to lower halfway, output an open-circuit feedback signal at the same time, and light up the half-down indicator light 26, clearly feeding back the action status of the rolling shutter door to the user. When a temperature detection signal is received, the system will further control the rolling shutter door to lower fully, output a feedback signal and light up the full-down indicator light 27 in the same way. The whole process accurately demonstrates the two-step descending linkage control logic of fire-resistant rolling shutters in real fire scenarios, and helps trainees understand the control logic and action steps of rolling shutter doors.

[0061] It enables the training device to get rid of the limitation of traditional simple simulation and can provide highly realistic, complex and changeable fire linkage operation experience for trainees. By actually operating the device, trainees can deeply understand and master how fire-resistant rolling shutters respond accurately according to different fire stages and signals in real fire scenarios, thereby effectively improving their ability to deal with actual fire situations.

[0062] The above embodiments are merely described in the preferred embodiment mode of this specification, and are not intended to limit the scope of this specification. Without departing from the design spirit of this specification, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of this specification shall all fall within the protection scope defined by the claims of this specification.
