Description

Technical Field

[0001] This invention belongs to the field of smoke and heat simulation technology, and specifically relates to a smoke and heat simulation training system and method. Background Technology

[0002] For fire safety, coal mining, and industrial production, smoke and heat training systems are essential components of rescue equipment, particularly respiratory protective gear. Regular training in simulated natural environments allows users to gain experience and improve their safety during daily tasks. Smoke and heat training systems can also assess users' physiological and psychological responses to stress. These systems are ideal for testing and training the limits of respiratory protective gear users' endurance. Smoke simulation training chambers provide realistic fire models and smoke scenarios, allowing trainees to understand and experience the actual conditions of a fire and smoke scene, and to conduct safe and controlled firefighting and emergency rescue drills using relevant personal protective equipment and emergency rescue equipment. This training enables firefighters to perform tactical maneuvers such as fire reconnaissance and personnel search and rescue in high-temperature, dense smoke, and other challenging environments, enhancing their rescue capabilities and psychological resilience in fire situations.

[0003] The purpose of firefighting is to eliminate potential hazards in work and daily life and prevent disasters. To ensure firefighters are adapted to fire environments and reduce unnecessary casualties during rescue operations, fire training simulates real fire conditions. However, some smoke training rooms currently suffer from unstable indoor environments, often exhibiting insufficient internal temperature or excessive air pressure. Current adjustment measures often involve reducing pressure when it is too high or increasing temperature when it is too low, without considering the relationship between temperature and pressure and coordinating their control. This leads to increased power consumption.

[0004] To address the aforementioned technical problems, this invention provides a smoke and heat simulation training system and method. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted:

[0006] According to one aspect of the present invention, a smoke and heat simulation training system is provided.

[0007] A smoke and heat simulation training system, characterized in that it specifically includes:

[0008] Controller, temperature sensor, pressure sensor, heating element, exhaust fan, power supply;

[0009] The controller reads the temperature signal from the temperature sensor and the internal pressure signal from the pressure sensor, and then uses different coordinated control strategies to control the exhaust fan and the heating device based on whether the temperature signal is below the temperature threshold or the pressure signal exceeds the pressure threshold.

[0010] Temperature sensors transmit temperature signals to the controller via a communication device. The controller then controls the heating device to increase its power to heat the interior of the main body and maintain the internal temperature. Pressure sensors transmit signals to the controller, which then controls the exhaust mechanism to draw out smoke from the main body, maintaining the internal pressure and ensuring the safety of firefighters. Different coordinated control strategies are adopted based on the specific circumstances under which temperature and pressure exceed the temperature and pressure thresholds.

[0011] By setting up a coordinated control strategy, the regulation of indoor pressure and temperature becomes more reliable, preventing situations where the pressure increases after the heating device starts working, requiring smoke extraction, and then the temperature decreases after smoke extraction, causing the heating device to continue working, thus preventing the overall system from reaching a stable state and consuming excessive electrical energy.

[0012] A further technical solution is that the temperature sensor is responsible for collecting temperature data and transmitting the above signals to the controller through a communication device.

[0013] A further technical solution is that the pressure sensor is responsible for collecting pressure data and transmitting the signal to the controller through a pressure device.

[0014] A further technical solution is that the heating device is responsible for generating heat according to the control requirements of the controller.

[0015] A further technical solution is that the exhaust fan is responsible for drawing out the flue gas according to the control requirements of the controller.

[0016] A further technical solution is that the power supply is responsible for supplying power to the controller, temperature sensor, pressure sensor, heating device, and exhaust fan.

[0017] A further technical solution involves determining the pressure and temperature change curves after the exhaust fan is in operation, based on the model and power of the exhaust fan, the building conditions, and the number of people.

[0018] A further technical solution involves determining the pressure and temperature change curves of the heating device after it starts working, based on the model and power of the heating device, the building conditions, and the number of people.

[0019] A further technical solution is that the coordinated control strategy is as follows: when the temperature is lower than the set temperature threshold or when the pressure is higher than the set pressure threshold, the controller comprehensively analyzes the pressure change curves and temperature change curves of the exhaust fan and the heating device after they have worked, and coordinates the operation of the exhaust fan and the heating device until the temperature rises above the set temperature threshold or the pressure drops below the set pressure threshold.

[0020] By coordinating the control of the exhaust fan and the heating device, the overall temperature and pressure control becomes more controllable, avoiding excessive energy consumption.

[0021] A further technical solution involves connecting the controller to the exhaust fan and the heating device via a frequency converter.

[0022] By setting up a frequency converter, the adjustment of the exhaust fan and heating device can be made more precise, thereby preventing the temperature and pressure data of the flue gas heating system from being unstable due to excessive adjustment of the exhaust fan and heating device.

[0023] A further technical solution involves setting a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is 90% of the temperature threshold and the second temperature threshold is 80% of the temperature threshold; and setting a first pressure threshold and a second pressure threshold, wherein the first threshold is 110% of the pressure threshold and the second threshold is 120% of the pressure threshold.

[0024] By setting multiple thresholds, the regulation of temperature and pressure becomes more standardized, preventing the exhaust fan and heating device from frequently adjusting their pressure and temperature data without exceeding the threshold, thus avoiding an increase in overall power consumption. At the same time, the control strategy can be optimized in a targeted manner based on different thresholds.

[0025] A further technical solution is that the temperature threshold and pressure threshold are set according to the building conditions, the number of people, and the training requirements.

[0026] By changing the settings, the configuration can be tailored to the specific needs of the device, thus providing greater flexibility.

[0027] A further technical solution is that when the temperature is below the first temperature threshold and the pressure is not yet above the first pressure threshold, or when the pressure is above the first pressure threshold and the temperature is above the first temperature threshold, no adjustment is made; when the temperature is below the first temperature threshold and the pressure is above the first pressure threshold, a first adjustment mode is adopted; when the temperature is below the second temperature threshold or the pressure is above the second pressure threshold, a second adjustment mode is adopted.

[0028] By adopting targeted adjustment measures under different temperature and pressure conditions, the regulation of temperature and pressure becomes more reliable, thereby achieving a better balance between temperature and pressure.

[0029] In the first adjustment mode, based on the comprehensive analysis of the pressure change curves and temperature change curves of the exhaust fan and the heating device after their operation by the controller, the exhaust fan is prioritized to operate. When the pressure drops below the preset pressure value, the heating device is then controlled to operate until the pressure and temperature meet the requirements.

[0030] In the second adjustment mode, the controller comprehensively analyzes the pressure and temperature change curves of the exhaust fan and heating device after they are in operation, and adjusts the exhaust fan and heating device simultaneously until the pressure and temperature meet the requirements.

[0031] A further technical solution includes an environmental control system, specifically: an industrial smoke generator to generate smoke; stage lights to simulate disaster scenarios; and speakers to simulate disaster sound effects.

[0032] The system utilizes an industrial smoke generator to produce smoke, with preset smoke concentrations. During training, the smoke concentration can be manually increased. Stage lights simulate disaster scenarios (high-end models can be equipped with electronic fire), and multiple scenarios can be preset. Speakers simulate disaster sound effects, and multiple scenarios can be preset.

[0033] A further technical solution includes a positioning device, specifically: a pressure sensor is installed on the floor to locate the position of personnel; an RFID reader is laid on the floor to locate the position and information of personnel.

[0034] A further technical solution is that the controller is connected to the positioning device, the environmental control system, and the audio system, and then transmits the data to the PC for processing.

[0035] After connection is established, the computer only functions as a monitor and issues commands; all control is handled by the controller. Different systems connect to the controller based on their communication protocols and interfaces. Through programming, the controller parses the received signals into data frames, then writes the supplementary data within each frame into RAM for standardized storage. The same data format is then used when pushing data to the PC. At this point, the various systems at the lower levels are transparent to the PC display; there's no need to consider the differences in interfaces and protocols between the controller and positioning devices, environmental control systems, audio systems, etc. Communication with the controller is directly achieved via the standard Modbus TCP protocol, allowing for data reading and command issuance. Equipment selection also eliminates the need to consider communication interfaces and supported protocols, reducing the complexity of equipment selection and indirectly lowering costs. The controller is a self-developed PCB circuit board product, offering a significant cost advantage compared to using PLC systems from other manufacturers.

[0036] On the other hand, the present invention provides a smoke and heat simulation training method, which uses the above-mentioned smoke and heat simulation training system to control the smoke and heat simulation training environment, specifically including:

[0037] The S1 temperature sensor collects temperature data, generates a temperature signal, and transmits the temperature signal to the controller; the pressure sensor collects pressure data, generates a pressure signal, and transmits the pressure signal to the controller.

[0038] The S2 controller is responsible for controlling the operation of the heating device and the exhaust mechanism by adopting corresponding coordinated control strategies based on the temperature signal from the temperature sensor and the pressure signal from the pressure sensor, and based on whether the temperature signal is below the temperature threshold or the pressure signal exceeds the pressure threshold.
