Description
Technical Field
[0001] The utility model relates to the technical field of fire simulation training equipment, in particular to a virtual and real step assessment device. Background Art
[0002] In the construction of real fire simulation training scenarios for firefighters, it is necessary to restore the complex environment of the fire accident scene as realistically as possible.
[0003] Most existing buildings are equipped with well-shaped deep structures such as ventilation shafts, cable shafts, pipe shafts and elevator shafts. These concealed structures do not cause safety impacts in daily life, but when a fire occurs, due to reduced visibility at the fire scene and damage to the well-shaped deep structures, it is difficult for firefighters entering the fire scene to accurately identify the safety of their routes. If they proceed rashly, they may suffer safety accidents such as stepping on empty air and falling to death, posing a great threat to the personal safety of firefighters.
[0004] Therefore, when performing rescue tasks in places with low visibility, firefighters need to perform front and back foot virtual and real steps, that is, a "false front and real back, slow exploratory" method of movement, to test whether there are traps in the front landing position, eliminate the risk of collapse, confirm the safety of the route, avoid stepping on air, and ensure the firefighters' own safety.
[0005] Therefore, in daily training, it is necessary to train and assess the virtual and real steps of firefighters, and this device is developed specifically for this purpose. Utility Model Content

[0020] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.
[0021] See also Figure 1-2 The utility model discloses a virtual and real step assessment device, which can be used for daily virtual and real step training and assessment of firefighters.
[0022] The virtual-real step assessment device includes a base plate 100, on which a lifting device 200 is arranged, and a mounting plate 300 is arranged on the movable part of the lifting device 200. At least one support plate 500 is arranged above the mounting plate 300, and a plurality of pressure sensors 400 are dispersedly arranged on the lower side of the support plate 500. A plurality of support columns 600 are dispersedly arranged directly below each support plate 500, and the support columns 600 are opposite to the pressure sensors 400 one by one. The lower ends of the support columns 600 are fixed on the mounting plate 300, and the upper ends are supported below the pressure points 401 of the pressure sensors 400.
[0023] The support plate 500 of the virtual-real step assessment device is used for walking and stepping during firefighter training or assessment. During the walking and stepping process of the firefighter, the pressure sensor 400 can specifically collect the pressure exerted on each support plate 500 and use it for back-end recording and analysis.
[0024] Among them, the lifting device 200 can generally be set to a default lifting state to raise the plane where the support plate 500 is located. When the firefighter steps on it, the lifting device 200 controls the support plate 500 to descend to simulate the collapse effect of the bottom plate 100.
[0025] Generally, when arranging the virtual and real step assessment device, a pit for arranging the device is provided on the arrangement site, and then the device is placed in the pit and the lifting device 200 lifts the support plate 500 to be flush with the ground.
[0026] Generally, the device can be in the form of one support plate 500 or multiple support plates 500 (each support plate 500 can be about 500 mm wide and 1000 mm long) to cope with various forms such as single-point position simulation and detection and large-scale layout simulation and detection. Therefore, the device has three forms.
[0027] In the first case, the virtual-real step assessment device has only one support plate 500, which is generally used for simulation and detection of a single point position.
[0028] In the second case, each virtual and real step assessment device is provided with a plurality of support plates 500 arranged in a line, such as Figure 1 As shown, the mounting plate 300 is rectangular, and a plurality of support plates 500 are arranged in a line along the length direction of the mounting plate 300, and the sides of the plurality of support plates 500 are adjacent to each other to cover the top of the mounting plate 300. This situation is generally used for simulation and detection on a line.
[0029] In the third case, the virtual and real step assessment device has support plates 500 arranged in a matrix within a range, the mounting plate 300 is rectangular, and multiple support plates 500 are arranged in a row on the same horizontal plane above the mounting plate 300, and the sides of the multiple support plates 500 are adjacent to each other to cover the top of the mounting plate 300. This is generally used for large-scale, team-based simulations, tests, and assessments within a region.
[0030] In general, the support column 600 supports the pressure point 401 of the pressure sensor 400 as follows: Figure 2 The contact support shown is not fixed between the two, which is convenient for later removal and maintenance of the support plate 500. The peripheral side of the pit limits the peripheral side of the support plate 500, and then the peripheral side surfaces are adjacent to each other to play a relative limit.
[0031] The lifting device 200 includes at least four reciprocating telescopic devices 201 distributed in a rectangular shape on the bottom plate 100. The lower end of the reciprocating telescopic device 201 is fixed on the bottom plate 100, and the upper end is a movable part, which is fixedly connected to the mounting plate 300. In order to improve the corresponding efficiency of the lifting device 200 in controlling the descent when simulating collapse, the reciprocating telescopic device 201 is a telescopic cylinder.
[0032] The mounting plate 300 is provided with a threading port 301, which is used to arrange the wiring of the pressure sensor 400. The pressure sensor 400 can be a weighing sensor of model SQB-500KG from Ningbo Keli.
[0033] Based on the above scheme, this virtual and real step assessment device uses a cylinder as the power source for collapse simulation. By connecting the pressure sensor 400 and the lifting device 200 to the PLC automatic control system, the automatic collapse and automatic recovery control of the device can be realized. Through the three forms or combined applications of this virtual and real step assessment device, the change scene of the training path can be simulated to more realistically restore the complex environment of the real fire scene. It has a wide range of applicable scenarios and can be applied to various training scenarios such as warehouses, shops, kitchens, bedrooms, offices, etc. By connecting the PLC automatic control system to the firefighter automatic assessment system, the automatic assessment function of the firefighter's virtual and real steps can be realized.
[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
