Description

Technical Field

[0001] The present invention belongs to the technical field of simulation training, and in particular relates to a reusable demolition training simulation device and method. Background Art

[0002] In the field of fire training technology, it is increasingly important to strengthen the skills training of firefighters, to promote development through learning, and to promote actual combat through training. Among them, demolition training is a required training subject for firefighters. However, before demolition training, they need to build walls by themselves, either brick walls or concrete walls, which brings great inconvenience to the training. In addition, walls are consumables and cannot be fully reused. The construction waste and dust generated after training are also a kind of damage to the environment.

[0003] The existing technical solutions lack the ability to achieve repetitive use of demolition training by simulating wall materials, strength and size, which can not only achieve training effects but also further improve training efficiency. In order to solve the above technical problems, the present invention provides a method and system for quantitative assessment of depression based on long-term electrocardiogram data. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a reusable demolition training simulation method, which is characterized by specifically comprising:

[0005] S11 determines the wall knocking force of the trainee through different pressure sensors inside the wall and the acceleration of the trainee's hammering device, and determines the evaluation value of the wall knocking force in combination with the force size of the wall knocking force and the force range of the wall, and divides the type of wall knocking force into effective knocking force and problematic knocking force based on the wall evaluation value;

[0006] S12 determines the threshold of the wall evaluation value of the simulated wall by using the simulated material and service life of the simulated wall, and divides the type of the effective knocking force into a high-efficiency knocking force and a low-efficiency knocking force in combination with the evaluation value of the wall knocking force;

[0007] S13 obtains the frequency and type of the wall knocking force of the trainee within a preset time period, and outputs the demolition force assessment amount of the trainee in combination with the number of different types of wall knocking force of the trainee within the preset time period. When the demolition force assessment amount of the trainee during the demolition process meets the requirements, proceeds to the next step;

[0008] S14 evaluates the demolition time of the simulated wall, and determines the training score of the trainee according to the demolition time, the number of different types of wall knocking forces within the demolition time, and the demolition force evaluation amount, and outputs the training result of the trainee according to the training score.

[0009] The beneficial effects of the present invention are:

[0010] By determining the evaluation value of the wall impact force according to the strength of the wall impact force and the force range of the wall, not only the difference in the strength of different wall impact forces is taken into account, but also the acceleration and force range of different wall impact forces are comprehensively considered, thereby achieving differentiated evaluation and differentiation of different wall impact forces.

[0011] By outputting the demolition force assessment of trainees based on the frequency and type of wall-impacting force applied by trainees within a preset time period and the number of different types of wall-impacting force applied, a comprehensive assessment of the demolition force applied by trainees based on the differences in different wall-impacting forces applied within a preset time period is achieved, laying the foundation for further dynamic adjustment of the force applied by trainees.

[0012] The training scores of trainees are determined by the demolition time, the number of different types of wall impact forces within the demolition time, and the demolition force assessment. This enables accurate assessment of training scores based on the demolition time taken by trainees and the force assessment during the demolition process, thereby improving the accuracy and pertinence of the training.

[0013] A further technical solution is that the wall is composed of a number of rectangular metal sheets shaped like bricks, and there is a pressure sensor at each of the four corners and the center, which are electrically connected to the control display screen with an analog-to-digital converter with a communication address.

[0014] A further technical solution is that the method for determining the evaluation value of the wall knocking force is:

[0015] Determine the acceleration of the hammering device of the trainee by using the accelerometer of the hammering device, and determine whether the wall striking force is a problematic striking force based on the acceleration, if so, determine that the wall striking force is a problematic striking force, if not, proceed to the next step;

[0016] Determine the magnitude of the wall knocking force through the pressure sensor inside the wall, and determine whether the wall knocking force of the trainee is a problematic knocking force based on the magnitude of the wall knocking force. If so, determine that the wall knocking force is a problematic knocking force. If not, proceed to the next step.

[0017] Determine the wall force range of the wall knocking force based on the pressure sensor inside the wall, and determine whether the wall knocking force of the trainee is a problematic knocking force based on the wall force range. If so, determine that the wall knocking force is a problematic knocking force; if not, proceed to the next step;

[0018] The evaluation value of the wall impact force is determined based on the wall force range, force magnitude and acceleration of the wall impact force.

[0019] A further technical solution is that the simulated wall is simulated by controlling the processor in the display screen in combination with the data of the pressure sensor and the accelerometer. Specifically, an algorithm formula is used to simulate the wall into a simulated wall with different areas, thicknesses and materials. At the same time, the hammering device can be simulated into a hammering device with different masses and hammering areas.

[0020] A further technical solution is that the wall evaluation value threshold of the simulated wall is determined according to the simulated material and service life of the simulated wall, wherein the higher the hardness of the simulated material of the simulated wall and the shorter the service life, the larger the wall evaluation value threshold.

[0021] A further technical solution is to classify the types of the effective knocking force into high-efficiency knocking force and low-efficiency knocking force in combination with the evaluation value of the wall knocking force, specifically including:

[0022] When the evaluation value of the wall knocking force is less than the wall evaluation value threshold, it is determined that the type of the effective knocking force is an inefficient knocking force; if not, it is determined that the type of the effective knocking force is an efficient knocking force.

[0023] A further technical solution is that the specific steps of determining the demolition force assessment amount of the training personnel are:

[0024] S21 obtains the frequency of the wall knocking force of the trainee within a preset time period, and determines whether the demolition force assessment amount of the trainee meets the requirements based on the frequency of the wall knocking rate. If so, proceed to the next step. If not, determine that the demolition force assessment amount of the trainee does not meet the requirements, and determine the demolition force assessment amount of the trainee based on the frequency of the wall knocking force of the trainee within the preset time period;

[0025] S22 determines the number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period according to the number of different types of knocking forces of the trainee in the preset time period, and judges whether the number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period is greater than the preset number, if so, proceeds to the next step, if not, proceeds to step S24;

[0026] S23 determines the knocking frequency of the effective knocking force of the trainee within the preset time period according to the effective knocking force of the trainee within the preset time period, and determines whether the demolition force assessment amount of the trainee meets the requirements according to the knocking frequency of the effective knocking force of the trainee within the preset time period, if so, proceeds to the next step, if not, determines that the demolition force assessment amount of the trainee does not meet the requirements, and determines the demolition force assessment amount of the trainee according to the knocking frequency of the effective knocking force of the trainee within the preset time period;

[0027] S24 determines the demolition force assessment amount of the trainee through the number of problematic knocking forces and inefficient knocking forces of the trainee within a preset time period, the knocking frequency of the effective knocking force within the preset time period, and the frequency of the wall knocking force.

[0028] A further technical solution is that the specific steps of determining the demolition force assessment amount of the training personnel are:

[0029] Acquire the frequency of the wall knocking force of the trainee within a preset time period, and determine the knocking frequency of the effective knocking force of the trainee within the preset time period according to the effective knocking force of the trainee within the preset time period;

[0030] When the frequency of the wall knocking rate and the knocking frequency of the effective knocking force of the trainee within the preset time period meet the requirements:

[0031] The number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period is determined by the number of different types of knocking forces of the trainee in the preset time period, and the demolition force assessment amount of the trainee is determined by the number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period, the knocking frequency of the effective knocking force in the preset time period, and the frequency of the wall knocking force;

[0032] When any one of the frequency of the wall knocking rate and the knocking frequency of the effective knocking force of the trainee within the preset time period fails to meet the requirements:

[0033] The demolition force assessment amount of the trainee is determined by the frequency of the wall knocking force of the trainee within a preset time period and the knocking frequency of the effective knocking force of the trainee within the preset time period.

[0034] A further technical solution is that the demolition time of the simulated wall is determined according to the number of wall fatigue limits of the simulated wall, and is specifically determined according to the simulated material and service life of the simulated wall.

[0035] A further technical solution is that the method for determining the training score of the trainer is:

[0036] S31: obtaining the breaking time of the trainee, and judging whether the breaking time of the trainee is greater than a preset time. If so, determining the training score of the trainee according to the breaking time of the trainee; if not, proceeding to the next step;

[0037] S32 determines whether there is a demolition force assessment amount less than a preset assessment amount through the demolition force assessment amount of the training personnel during the demolition time, if yes, proceeds to step S33, if no, proceeds to step S34;

[0038] S33 determines the number of problematic knocking forces and inefficient knocking forces of the trainee during the demolition time by the number of different types of knocking forces of the trainee during the demolition time, and judges whether the number of problematic knocking forces and inefficient knocking forces of the trainee during the demolition time is greater than a preset knocking number; if so, determines the training score of the trainee by the number of demolition force assessment amounts of the trainee during the demolition time that is less than a preset assessment amount; if not, proceeds to the next step;

[0039] S34 determines the training score of the trainee based on the number of problematic striking forces and inefficient striking forces of the trainee during the demolition time, the minimum value of the demolition force evaluation amount during the demolition time, and the demolition time of the trainee.

[0040] On the other hand, an embodiment of the present application provides a reusable demolition training simulation device, which adopts the above-mentioned reusable demolition training simulation method, and is characterized in that it specifically includes:

[0054] Example 1

[0055] In order to solve the above technical problems, Figure 1 As shown, the present invention provides a reusable demolition training simulation method, which is characterized by specifically comprising:

[0056] S11 determines the wall knocking force of the trainee through different pressure sensors inside the wall and the acceleration of the trainee's hammering device, and determines the evaluation value of the wall knocking force in combination with the force size of the wall knocking force and the force range of the wall, and divides the type of wall knocking force into effective knocking force and problematic knocking force based on the wall evaluation value;

[0057] It should be noted that the wall is composed of a number of rectangular metal sheets shaped like bricks, and there is a pressure sensor at each of the four corners and the center, which are electrically connected to the control display screen with an analog-to-digital converter with a communication address.

[0058] In one possible embodiment, the method for determining the evaluation value of the wall impact force is:

[0059] Determine the acceleration of the hammering device of the trainee by using the accelerometer of the hammering device, and determine whether the wall striking force is a problematic striking force based on the acceleration, if so, determine that the wall striking force is a problematic striking force, if not, proceed to the next step;

[0060] Determine the magnitude of the wall knocking force through the pressure sensor inside the wall, and determine whether the wall knocking force of the trainee is a problematic knocking force based on the magnitude of the wall knocking force. If so, determine that the wall knocking force is a problematic knocking force. If not, proceed to the next step.

[0061] Determine the wall force range of the wall knocking force based on the pressure sensor inside the wall, and determine whether the wall knocking force of the trainee is a problematic knocking force based on the wall force range. If so, determine that the wall knocking force is a problematic knocking force; if not, proceed to the next step;

[0062] The evaluation value of the wall impact force is determined based on the wall force range, force magnitude and acceleration of the wall impact force.

[0063] Furthermore, the simulated wall is simulated by controlling the processor in the display screen in combination with the data from the pressure sensor and the accelerometer. Specifically, an algorithm formula is used to simulate the wall into a simulated wall with different areas, thicknesses, and materials. At the same time, the hammering device can be simulated into a hammering device with different masses and different hammering areas.

[0064] The algorithm is based on:

[0065] Wall area formula: wall area (m2) = wall length (m) * wall height (m);

[0066] Wall weight formula: Wall weight (kg) = wall thickness (m) * wall area (m2) * wall density (kg / m 3 );

[0067] Wall material strength formula: Wall material strength value (Mpa) = normal pressure borne by the wall material (N) / wall area (m2);

[0068] The normal pressure borne by the wall material usually refers to the normal static pressure per unit area that the material can withstand. Without considering the influence of other factors, such as shear force, bending force and deformation, it is equivalent to: the normal pressure borne by the wall material (N) = design strength (Mpa) x wall thickness (m);

[0069] Hammer force formula: Hammer force (N) = hammer mass (kg) x acceleration (m / s 2 );

[0070] Hammer strength = hammer force (N) / hammer area (m 2 );

[0071] Brick wall destructive force formula: total destructive force (J) = destructive strength per unit area of ​​the wall (Mpa) x total area of ​​the wall (m 2 );

[0072] Destructive strength per unit area of ​​the wall (Mpa) = strength per unit area of ​​the wall (Mpa) x force-bearing width of the wall (m);

[0073] The destructive force of a single hammer blow (J) = the force applied to the pressure sensor (N) x the distance from the person standing measured by the distance sensor (m);

[0074] Here, only the load of the demolition tool mass within the normal range is considered, and the change in acceleration caused by excessive mass is not considered. When simulating demolition tools of different masses, the formula should become:

[0075] The destructive force of a single hammer blow (J) = {force on the pressure sensor (N) + hammer blow force (N)} x the distance of the person standing measured by the distance sensor (m);

[0076] Then the total destructive force (J) = ∑ the destructive force of a single hammer blow (J);

[0077] Without considering other factors, the strength per unit area of ​​the wall is equivalent to the strength value of the wall material.

[0078] Wall fatigue limit (times) = wall durability (times) * (1-∑ hammer strength / wall material strength);

[0079] The specific formula varies depending on the material and component. Take the force width calculation formula of common materials as an example.

[0080] The calculation formula for the load-bearing width of the concrete wall is: b = 0.2h ~ 0.8h (h is the wall thickness);

[0081] The calculation formula for the force-bearing width of a brick wall is generally selected and calculated based on factors such as the structural material, size and quality of the brick wall masonry. The specific formula is as follows:

[0082] Calculation formula for the force-bearing width of a brick wall:

[0083] b = min (0.03h + 60, 0, 67i) (h is the wall thickness, i is the wall height);

[0084] The theoretical durability of the wall structure can be calculated based on factors such as the design strength of the wall, the strength and quality of cement and other materials. The following formula can generally be used: N = CVKF;

[0085] Wherein, N: theoretical performance index of wall structure, which can be indexes such as strength and pressure resistance;

[0086] C: Design strength of the wall;

[0087] V: strength coefficient of cement material used in the wall;

[0088] K: Adaptability coefficient in wall design, considering the influence of various factors such as the wall on the actual strength;

[0089] F: The mass coefficient of the wall material, taking into account the influence of the material properties of the wall and the mass of the wall on the actual strength.

[0090] During the calculation process, it is necessary to consider factors such as the wall's use environment, construction quality, and the specific values ​​of the coefficients and parameters used in the formula in order to obtain a more accurate theoretical durability value of the wall structure.

[0091] According to GB50010-2010, the range and calculation method of the adaptability coefficient and material coefficient of concrete are as follows:

[0092] Adaptation coefficient K:

[0093] Ordinary concrete:

[0094] K = 1.0, when the strength grade of concrete meets the requirements of the specification, and the mix proportion and material quality meet the requirements;

[0095] K = 0.9 ~ 1.0, when a small amount of cracks or local bubbles appear in the concrete;

[0096] K = 0.8 ~ 0.9, when there are many cracks, hollows, pollution or loose quality problems in the concrete;

[0097] High-strength concrete and high-performance concrete:

[0098] Based on the concrete compressive grade strength and actual strength results, find the corresponding adaptation factor from the following.

[0099] F = 1.0, when cement meets the specification requirements, aggregate meets the specified grade, and sand and fly ash meet the specified usage requirements;

[0100] F = 0.9 ~ 1.0, when one of the materials in the concrete, such as sand, aggregate, fly ash, etc., does not meet the requirements of the specification;

[0101] F = 0.8 ~ 0.9, when two of the materials in the concrete, such as sand, aggregate, and fly ash, do not meet the requirements of the specification;

[0102] F=0.7~0.8, when three or more materials such as sand, aggregate, fly ash, etc. in the concrete do not meet the specification requirements or there are quality problems such as arbitrary addition of materials.

[0103] Where F is the material coefficient.

[0104] V refers to the strength coefficient of the cement material used in concrete, and its calculation method is as follows:

[0105] For cement grades PO 32.5 and PO 42.5, the V value is 1.00;

[0106] The V value of cement with a grade of PO 52.5 is 0.95;

[0107] The V values ​​of cement grades PC 32.5, PC 42.5 and PC 52.5 are 0.95, 1.00 and 1.05 respectively.

[0108] Among them, PO stands for ordinary Portland cement and PC stands for mineral admixture Portland cement.

[0109] Under the premise that F, K, and V meet the specifications, N = C. The theoretical performance index of the wall structure is the design strength, and the formula is: wall durability = design strength.

[0110] According to the "Concrete Structure Design Code", ordinary concrete is divided into fourteen grades, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80. The corresponding strength of each grade is 15Mpa, 20Mpa, 25Mpa, 30Mpa, 35Mpa, 40Mpa, 45Mpa, 50Mpa, 55Mpa, 60Mpa, 65Mpa, 70Mpa, 75Mpa, 80Mpa.

[0111] The fatigue limit and destructive force parameters of the wall are considered during the simulated demolition process. When all of them approach the limit, the wall is considered to be successfully destroyed.

[0112] For example, if a brick wall or concrete has one of fourteen levels of strength to simulate the wall size, area and thickness, according to the algorithm, the trainee only needs to select one of the fourteen levels of brick wall or concrete, and then select the wall size, area and thickness, and the control display screen 3 will calculate it automatically.

[0113] It can also simulate demolition tools with different masses and hammer surface areas. The trainer only needs to modify the mass and hammer surface area, and the control display screen 3 will calculate it automatically. Through the algorithm, the wall set by the trainer, after the trainer uses the demolition tool to hit the wall several times, the control display screen 3 will prompt the demolition progress.

[0114] Total destructive force (J) = strength per unit area of ​​the wall (Mpa) X width of the wall under load (m); X total area of ​​the wall (m2); where the unit area of ​​the wall is NX wall thickness (m), and the wall thickness can be modified at will; the width of the wall under load is the surface width of the demolition tool hammering (modified at will); the total destructive force is the force that the wall can withstand.

[0115] The destructive force of a single hammer blow (J) = {force exerted on the pressure sensor (N) + hammer mass (kg) X acceleration (m / s2)} X the distance of the person standing measured by the ranging sensor (m); the force exerted on the pressure sensor will be directly measured; the hammer mass can be modified at will; the distance of the person standing (m) measured by the ranging sensor will be directly measured.

[0116] When the sum of the destructive force (J) of each hammer blow reaches the total destructive force (J), it is determined that the wall destructive force has reached its limit.

[0117] Wall fatigue limit (times) = wall durability (times) X (1-∑ hammer strength / wall material strength); hammer strength = hammer force (N) / hammer area (m2), hammer force (N) = hammer mass (kg) X acceleration (m / s2), hammer mass can be modified at will; wall material strength is NX wall thickness (m), wall thickness can be modified at will; wall durability = design strength, design strength is given by an example, such as one of the fourteen grades of concrete.

[0118] When the fatigue limit of the wall approaches zero, it is considered that the fatigue of the wall has reached the limit.

[0119] Therefore, when the sum of the destructive force of each hammer blow reaches the total destructive force and the fatigue limit of the wall approaches zero, the wall is considered to be successfully destroyed.

[0120] S12 determines the threshold of the wall evaluation value of the simulated wall by using the simulated material and service life of the simulated wall, and divides the type of the effective knocking force into a high-efficiency knocking force and a low-efficiency knocking force in combination with the evaluation value of the wall knocking force;

[0121] It should be noted that the wall evaluation value threshold of the simulated wall is determined according to the simulated material and service life of the simulated wall. The higher the hardness of the simulated material of the simulated wall and the shorter the service life, the larger the wall evaluation value threshold.

[0122] It should be noted that the types of the effective knocking force are divided into high-efficiency knocking force and low-efficiency knocking force in combination with the evaluation value of the wall knocking force, specifically including:

[0123] When the evaluation value of the wall knocking force is less than the wall evaluation value threshold, it is determined that the type of the effective knocking force is an inefficient knocking force; if not, it is determined that the type of the effective knocking force is an efficient knocking force.

[0124] S13 obtains the frequency and type of the wall knocking force of the trainee within a preset time period, and outputs the demolition force assessment amount of the trainee in combination with the number of different types of wall knocking force of the trainee within the preset time period. When the demolition force assessment amount of the trainee during the demolition process meets the requirements, proceeds to the next step;

[0125] In one possible embodiment, Figure 2 As shown, the specific steps for determining the demolition force assessment amount of the trainer are:

[0126] S21 obtains the frequency of the wall knocking force of the trainee within a preset time period, and determines whether the demolition force assessment amount of the trainee meets the requirements based on the frequency of the wall knocking rate. If so, proceed to the next step. If not, determine that the demolition force assessment amount of the trainee does not meet the requirements, and determine the demolition force assessment amount of the trainee based on the frequency of the wall knocking force of the trainee within the preset time period;

[0127] S22 determines the number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period according to the number of different types of knocking forces of the trainee in the preset time period, and judges whether the number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period is greater than the preset number, if so, proceeds to the next step, if not, proceeds to step S24;

[0128] S23 determines the knocking frequency of the effective knocking force of the trainee within the preset time period according to the effective knocking force of the trainee within the preset time period, and determines whether the demolition force assessment amount of the trainee meets the requirements according to the knocking frequency of the effective knocking force of the trainee within the preset time period, if so, proceeds to the next step, if not, determines that the demolition force assessment amount of the trainee does not meet the requirements, and determines the demolition force assessment amount of the trainee according to the knocking frequency of the effective knocking force of the trainee within the preset time period;

[0129] S24 determines the demolition force assessment amount of the trainee through the number of problematic knocking forces and inefficient knocking forces of the trainee within a preset time period, the knocking frequency of the effective knocking force within the preset time period, and the frequency of the wall knocking force.

[0130] Furthermore, when the estimated amount of breaking force used by the trainee during the breaking process does not meet the requirement, it is output that the breaking force cannot meet the requirement, and a suggestion on breaking force is output based on the estimated amount of breaking force used by the trainee.

[0131] In another possible embodiment, the specific steps of determining the demolition force assessment amount of the trainer are:

[0132] Acquire the frequency of the wall knocking force of the trainee within a preset time period, and determine the knocking frequency of the effective knocking force of the trainee within the preset time period according to the effective knocking force of the trainee within the preset time period;

[0133] When the frequency of the wall knocking rate and the knocking frequency of the effective knocking force of the trainee within the preset time period meet the requirements:

[0134] The number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period is determined by the number of different types of knocking forces of the trainee in the preset time period, and the demolition force assessment amount of the trainee is determined by the number of problematic knocking forces and inefficient knocking forces of the trainee in the preset time period, the knocking frequency of the effective knocking force in the preset time period, and the frequency of the wall knocking force;

[0135] When any one of the frequency of the wall knocking rate and the knocking frequency of the effective knocking force of the trainee within the preset time period fails to meet the requirements:

[0136] The demolition force assessment amount of the trainee is determined by the frequency of the wall knocking force of the trainee within a preset time period and the knocking frequency of the effective knocking force of the trainee within the preset time period.

[0137] S14 evaluates the demolition time of the simulated wall, and determines the training score of the trainee according to the demolition time, the number of different types of wall knocking forces within the demolition time, and the demolition force evaluation amount, and outputs the training result of the trainee according to the training score.

[0138] Furthermore, the demolition time of the simulated wall is determined according to the number of wall fatigue limits of the simulated wall, and is specifically determined according to the simulated material and service life of the simulated wall.

[0139] In one possible embodiment, the method for determining the training score of the trainer is:
