Description

Technical Field

[0001] The invention relates to the technical field of building fire protection, and in particular to a smoke exhaust fire damper that can be remotely controlled. Background Art

[0002] In the prior art, the controller module often directly sends control instructions based on the data of sensors (such as temperature sensors and smoke sensors) to control the opening or closing of smoke exhaust fire dampers. However, this direct control method has significant defects.

[0003] First, there is a lack of situational judgment mechanism. In complex fire scenarios, sensor data may be affected by a variety of factors, such as environmental noise, equipment failure, etc., resulting in data anomalies or false alarms. If the controller module does not have the ability to judge the situation, it may make wrong control decisions based on inaccurate data, resulting in erroneous operations or untimely responses.

[0004] Secondly, the existing technology lacks a command priority processing mechanism. In emergency situations, such as the early stages of a fire, manual control commands are often more accurate and timely than automatic control commands. However, existing systems are usually unable to distinguish the priorities of control commands from different sources or types, resulting in the inability to prioritize manual control commands in emergency situations, thereby delaying the best time for smoke exhaust and fire prevention.

[0005] In addition, the smoke exhaust fire damper system in the prior art also has problems such as slow response speed, low accuracy, frequent misoperation, etc. These problems not only affect the overall performance of the system, but also may pose a serious threat to the safety of personnel and property.

[0006] In order to overcome these defects of the prior art, the present invention proposes a remotely controlled smoke exhaust fire damper system. The system uses a controller module to first perform scenario judgment based on sensor data, and set the highest priority for manual control instructions, as well as logical judgment rules based on smoke concentration and temperature thresholds, and then send corresponding control instructions to the actuator according to the judgment results. This solution can more accurately identify control scenarios, ensure that manual control instructions are executed first in emergency situations, and flexibly control the opening and closing of the valve body module blades according to smoke and temperature conditions. In this way, the present invention effectively improves the response speed and accuracy of the system, reduces the possibility of misoperation, and thus significantly improves the overall performance and safety of the smoke exhaust fire damper system. Summary of the invention

[0007] In order to overcome the problems raised in the above background technology, the present invention proposes a smoke exhaust fire damper that can be remotely controlled.

[0009] Preferably, the sensor and the execution module include: A11: Temperature sensor, used to monitor the temperature change data in the environment around the smoke exhaust fire damper; A12: Smoke sensor, used to detect smoke in the environment around the smoke exhaust fire damper; A13: Actuator, used to receive signals from the controller and convert them into mechanical actions to drive the valve body module blades to open and close.

[0010] Preferably, the controller module includes the following steps when processing the data of the sensor and the execution module and performing logical judgment: S11: Data reception, the controller module receives real-time data from the temperature sensor and the smoke sensor through the communication interface; S12: Data processing: analyzing and processing the received data, calculating the temperature change rate and the change trend of smoke concentration; S13: Logical judgment: the controller module performs logical judgment on the processed data according to preset logical rules and thresholds; S14: Decision making: according to the results of logical judgment, make corresponding control decisions and convert the decisions into specific control instructions.

[0011] Preferably, when the controller module sends a control instruction according to the result of the logic judgment, the following steps are included: S21: Scenario judgment: judging the control scenario based on the data of the temperature sensor and the smoke sensor. When there is no abnormal change in the data of the temperature sensor and the smoke sensor, it is judged as a normal scenario. When there is an abnormal change in the data of the temperature sensor and the smoke sensor, it is judged as an abnormal scenario. S22: Sending scene instructions: Editing corresponding control instructions according to the determined control scene, and sending the control instructions to the actuator. The instructions of the normal scene are that the control actuator performs actions according to the subsequent instructions, and the instructions of the abnormal scene are that the control actuator does not receive the control instructions sent by the controller module within the specified time, and keeps the valve body module blade closed; S23: Sending a control instruction: sending the control instruction formulated in step S14 to the actuator to control the opening and closing of the blades of the valve body module.

[0012] Preferably, when the controller module performs logical judgment on the processed data according to the preset logical rules and thresholds, the preset logical rules and thresholds are: A21: The manual control command has the highest priority, that is, the manual control command sent by the remote control module is executed first; A22: When the smoke concentration value increases and the temperature does not reach the set threshold, the control valve module blade opens; A23: When the temperature reaches the set threshold, the control valve module blade closes.

[0014] As a preferred embodiment, when the remote control module establishes a short-distance communication network to realize data exchange and linkage between multiple groups of smoke exhaust and fire dampers, the principle steps are as follows: Multiple groups of smoke exhaust fire dampers are grouped according to the areas of action. The smoke exhaust fire dampers in the same area are divided into the same group. A short-distance communication network is established among the smoke exhaust fire dampers in the same group to achieve mutual communication. When any group of smoke exhaust fire dampers in the same group recognizes abnormal data, the remaining smoke exhaust fire dampers will close the blades of the valve body module after a set time delay, wherein the time delay is set according to the type and quantity of items in the area.

[0015] Preferably, when the remote control module allows an authorized user to send a control instruction remotely, the data transmission process is: S31: The user compiles a manual control instruction through one of the software and the applet, encrypts the manual control instruction, and then sends it to the remote control module; S32: After receiving the encrypted manual control instruction, the remote control module decrypts it and calls the instruction code in the database to obtain the code related to the manual control instruction; S33: The remote control module encrypts the retrieved code using the timestamp to obtain an encrypted instruction, and sends the encrypted instruction to the controller module.

Once the fault is confirmed, the security module sends an alarm message to the administrator through a preset alarm method.

[0017] Preferably, the power module includes: A41: Main power supply, used to provide the system with power required for normal operation; A42: Backup power supply, used to provide power to the system when the main power fails, ensuring that the fire damper can work normally in the event of power outage and circuit failure; A43: Emergency power supply, used to provide emergency power to the actuator in case of abnormal situation and damage of main power supply and backup power supply, so that the valve body module blades are closed.

[0018] Beneficial effects of the present invention: 1. Compared with the prior art in which the controller module directly sends control instructions based on sensor data, lacks scenario judgment and instruction priority processing, which may lead to shortcomings such as untimely response or misoperation, this solution adopts a solution in which the controller module first makes scenario judgment based on sensor data, sets the highest priority for manual control instructions, and uses logical judgment rules based on smoke concentration and temperature thresholds, and then sends corresponding control instructions to the actuator based on the judgment results. This solution can more accurately identify control scenarios, ensure that manual control instructions are executed first in emergency situations, and flexibly control the opening and closing of the valve body module blades according to smoke and temperature conditions, effectively improving the response speed and accuracy of the system, reducing the possibility of misoperation, and thus improving the overall performance and safety of the smoke exhaust and fire damper system; 2.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1-2 The present invention provides an embodiment: a smoke exhaust fire damper that can be remotely controlled, comprising: The valve body module, as the main structure of the smoke and fire damper, is responsible for accommodating and protecting other key components; Sensor and execution modules are used to monitor changes in the surrounding environment and trigger alarms and execute actions when preset conditions are met; The controller module is used to process the data from the sensor and the execution module, perform logical judgment, and then send control instructions based on the results of the logical judgment; A remote control module for providing a user interface, allowing an authorized user to remotely monitor the status of the smoke and fire dampers and send control instructions, and to control the communication network; Safety module, used to monitor the system's operating status, detect and report faults in a timely manner; The power module is used to provide stable and reliable power support for the system.

[0022] As described above, the working principle of the remotely controllable smoke exhaust and fire damper system is as follows: the system monitors the temperature and smoke conditions of the environment around the smoke exhaust and fire damper in real time through the sensor module, and transmits the data to the controller module; the controller module analyzes and processes the received data, makes logical judgments based on preset logical rules and thresholds, formulates corresponding control decisions, and sends control instructions to the actuator; after receiving the instructions, the actuator converts them into mechanical actions to drive the opening and closing of the blades of the valve body module to realize the functions of smoke exhaust and fire prevention; at the same time, the remote control module allows authorized users to remotely monitor the status of the smoke exhaust and fire damper and send control instructions, the security module monitors the system operation status and reports faults, and the power module provides stable and reliable power support for the system.

[0024] Preferably, the controller module includes the following steps when processing the data of the sensor and the execution module and performing logical judgment: S11: Data reception, the controller module receives real-time data from the temperature sensor and the smoke sensor through the communication interface; S12: Data processing: analyzing and processing the received data, calculating the temperature change rate and the change trend of smoke concentration; S13: Logical judgment: the controller module performs logical judgment on the processed data according to preset logical rules and thresholds; S14: Decision making: according to the results of logical judgment, make corresponding control decisions and convert the decisions into specific control instructions.

[0025] As described above, this technical solution, through the data reception, processing, logical judgment and decision-making steps implemented by the controller module, can efficiently analyze the data of the temperature sensor and the smoke sensor in real time, accurately calculate the temperature change and smoke concentration trend, and quickly make logical judgments according to preset rules. Based on this, it can formulate and execute precise control instructions, thereby significantly improving the response speed and decision-making accuracy of the smoke exhaust and fire damper system, and effectively ensuring fire safety.

[0026] Preferably, when the controller module sends a control instruction according to the result of the logic judgment, the following steps are included: S21: Scenario judgment: judging the control scenario based on the data of the temperature sensor and the smoke sensor. When there is no abnormal change in the data of the temperature sensor and the smoke sensor, it is judged as a normal scenario. When there is an abnormal change in the data of the temperature sensor and the smoke sensor, it is judged as an abnormal scenario. S22: Sending scene instructions: Editing corresponding control instructions according to the determined control scene, and sending the control instructions to the actuator. The instructions of the normal scene are that the control actuator performs actions according to the subsequent instructions, and the instructions of the abnormal scene are that the control actuator does not receive the control instructions sent by the controller module within the specified time, and keeps the valve body module blade closed; S23: Sending a control instruction: sending the control instruction formulated in step S14 to the actuator to control the opening and closing of the blades of the valve body module.

[0027] Preferably, when the controller module performs logical judgment on the processed data according to the preset logical rules and thresholds, the preset logical rules and thresholds are: A21: The manual control command has the highest priority, that is, the manual control command sent by the remote control module is executed first; A22: When the smoke concentration value increases and the temperature does not reach the set threshold, the control valve module blade opens; A23: When the temperature reaches the set threshold, the control valve module blade closes.

[0028] Compared with the prior art, in which the controller module directly sends control instructions based on sensor data, lacks scenario judgment and instruction priority processing, which may lead to shortcomings such as untimely response or misoperation, this solution adopts a solution in which the controller module first makes scenario judgments based on sensor data, sets the highest priority for manual control instructions, and uses logical judgment rules based on smoke concentration and temperature thresholds, and then sends corresponding control instructions to the actuator based on the judgment results. This solution can more accurately identify control scenarios, ensure that manual control instructions are executed first in emergency situations, and flexibly control the opening and closing of the valve body module blades according to smoke and temperature conditions, effectively improving the response speed and accuracy of the system, reducing the possibility of misoperation, and thus improving the overall performance and safety of the smoke exhaust and fire damper system.

[0029] Preferably, the remote control module also has the following functions: A31: Data transmission with the fire protection system, guiding the controller module to control the opening and closing of the blades of the valve body module according to the specific data of the fire protection system; A32: Establish a short-distance communication network to realize data exchange and linkage between multiple groups of smoke exhaust and fire dampers; A33: decrypt the received data and detect the correctness and security of the received data; A34: The data to be sent is encrypted and sent to the user, so that the authorized user can remotely monitor the status of the smoke exhaust fire damper.

[0030] As a preferred embodiment, when the remote control module establishes a short-distance communication network to realize data exchange and linkage between multiple groups of smoke exhaust and fire dampers, the principle steps are as follows: Multiple groups of smoke exhaust fire dampers are grouped according to the areas of action. The smoke exhaust fire dampers in the same area are divided into the same group. A short-distance communication network is established among the smoke exhaust fire dampers in the same group to achieve mutual communication. When any group of smoke exhaust fire dampers in the same group recognizes abnormal data, the remaining smoke exhaust fire dampers will close the blades of the valve body module after a set time delay, wherein the time delay is set according to the type and quantity of items in the area.

[0031] Compared with the existing technology, which has a single function of remote control module, lacks deep integration with fire protection system, multi-device linkage capability and data transmission security guarantee, this solution uses remote control module and fire protection system to realize data transmission and guide the controller module to control accurately; at the same time, a short-distance communication network is established to realize data exchange and intelligent linkage of multiple groups of smoke exhaust fire dampers in the area, and set delayed closing strategy according to the characteristics of objects in the area; in addition, the encryption and decryption function of data transmission is enhanced to ensure the security and correctness of data. This solution significantly improves the intelligence level, response speed and safety of smoke exhaust fire damper system, and provides more reliable technical support for fire prevention and emergency response.

[0032] Preferably, when the remote control module allows an authorized user to send a control instruction remotely, the data transmission process is: S31: The user compiles a manual control instruction through one of the software and the applet, encrypts the manual control instruction, and then sends it to the remote control module; S32: After receiving the encrypted manual control instruction, the remote control module decrypts it and calls the instruction code in the database to obtain the code related to the manual control instruction; S33: The remote control module encrypts the retrieved code using the timestamp to obtain an encrypted instruction, and sends the encrypted instruction to the controller module.

[0033] Compared with the prior art in which the remote control module directly transmits plain text control instructions, lacks data encryption and timestamp verification, and has the risk of data being stolen or tampered with, this solution adopts the solution that the user compiles and encrypts manual control instructions through software or applet, and the remote control module decrypts and calls the instruction code in the database for secondary encryption (using timestamp) after receiving it, and then sends the encrypted instruction to the controller module. This solution effectively enhances the security of data transmission, protects the confidentiality and integrity of control instructions through a double encryption mechanism, and at the same time, the addition of timestamps improves the timeliness and authenticity of data, thereby ensuring the accuracy and high security of remote control instructions.

[0034] Preferably, the safety module includes the following steps when monitoring the operating status of the system and promptly discovering and reporting faults: S41: data collection, collecting operation status data from the monitored system components through specific interfaces and protocols, wherein the operation status data includes CPU usage, memory usage and network traffic; S42: Data analysis: Real-time analysis of the collected data, and judging whether there is any abnormality in the system by comparing the pattern recognition algorithm; S43: Fault determination: when the data analysis results show that the system is abnormal, the safety module further analyzes the nature and severity of the abnormality to determine whether to trigger an alarm; S44: Alarm notification. Once the fault is confirmed, the security module sends an alarm message to the administrator through a preset alarm method.

[0035] As described above, compared with the existing technology, the security module lacks comprehensive data collection, in-depth data analysis and fault determination mechanism, which leads to the disadvantages of delayed fault detection or high false alarm rate. This solution uses the security module to comprehensively collect the operating status data of system components through specific interfaces and protocols, and uses pattern recognition algorithms for real-time analysis to accurately determine system abnormalities and their severity. Once the fault is confirmed, the administrator is notified in a preset manner in a timely manner. This solution significantly improves the accuracy and timeliness of fault detection, reduces the false alarm rate, and provides a strong guarantee for the stable operation of the system.

[0036] Preferably, the power module includes: A41: Main power supply, used to provide the system with power required for normal operation; A42: Backup power supply, used to provide power to the system when the main power fails, ensuring that the fire damper can work normally in the event of power outage and circuit failure; A43: Emergency power supply, used to provide emergency power to the actuator in case of abnormal situation and damage of main power supply and backup power supply, so that the valve body module blades are closed.

[0037] As described above, compared with the prior art in which the power module design is single and lacks redundancy and emergency power guarantee, which may cause the system to fail to work normally in the event of a power failure, the present invention adopts a multi-level power module design including a main power supply, a backup power supply and an emergency power supply, ensuring that the system can continue to supply power under normal, faulty and abnormal conditions. In particular, the addition of an emergency power supply can ensure the timely closure of the fire damper in extreme cases, thereby greatly improving the reliability and safety of the system.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
