Description

Technical Field

[0001] This invention relates to the field of fire detection equipment technology, specifically to a cleaning and calibration platform for a smoke and heat detector false alarm correction system. Background Technology

[0002] Currently, subway stations mainly use ordinary smoke detectors, while depots mainly use aspirating smoke detectors. Ordinary smoke detectors are prone to malfunctions and false fire alarms in summer, humid seasons, when there is water leakage in the station, or when there is a lot of dust in the station. This is because water and dust can affect the sensor's judgment. Aspirating smoke detectors are also susceptible to problems such as structural water leakage, condensation, and rainwater leakage, which can lead to equipment short circuits and terminal card burnout.

[0003] Although the installation of industrial dehumidification equipment can control ambient humidity and improve the equipment's protection level to enhance the stability of the equipment's operation, thus reducing the damage rate of smoke detectors, the effect is limited.

[0004] As subway operations continue, various equipment and facilities along the subway lines gradually enter their maintenance and upkeep cycle, especially smoke detectors, which are prone to accumulating dust and dirt over long periods of operation, affecting their sensitivity and accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning and calibration platform for a smoke and temperature detector false alarm mitigation system. This integrated platform uses data analysis to locate the device to be cleaned. After cleaning, threshold calibration and platform simulation testing are performed to prevent direct online operation and secondary false alarms. This solves the problem of high false alarms and high failure rates in subway smoke and temperature detectors caused by dust and moisture condensation, extending the equipment's lifespan. A smoke detector moisture-proof testing and research platform is used for comparative simulation experiments to obtain the equipment's operating status under different temperature and dust conditions, providing experimental basis for the protection and treatment of damp locations. The protective coating and base cold-press cap inhibit short-circuit damage to the mainboard caused by condensation and dust. Pilot applications solidify and establish standards for existing line upgrades, new line technologies, and detector maintenance and repair, reducing equipment maintenance and personnel costs, and solving the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The smoke and heat detector false alarm correction system cleaning and calibration platform includes: a data and smoke detector cleaning platform, a smoke detector status testing and threshold calibration platform, and a smoke detector moisture-proof testing and research platform; The data and smoke detector cleaning platform is configured to monitor the working status of smoke detectors in real time, collect alarm, fault and shielding data of the detectors; analyze the collected data to determine the critical value of the smoke detectors and identify detectors that need to be cleaned or replaced. The smoke detector status test and threshold calibration platform is configured to perform data calibration on the smoke detector after cleaning, and connect to the test platform for performance verification. After passing the verification, it is delivered to the field for use. The smoke detector moisture-proof testing and research platform is configured to simulate various on-site environmental conditions, test the smoke detectors in the testing platform, compare the changes in alarms, parameters and operational stability of smoke detectors with and without protective coatings under different environments, and output on-site handling solutions for damp locations.

[0007] Furthermore, the data and smoke detector cleaning platform includes: The cleaning plan generation module is configured to generate corresponding cleaning operation plans based on data analysis results. The task management module is configured to allocate and execute cleaning tasks according to the cleaning operation plan, track task progress, and record cleaning results.

[0008] Furthermore, the smoke detection state testing and threshold calibration platform includes: The file management module is configured to create equipment files for smoke detectors, and to record the installation location, usage time and maintenance records of smoke and heat detectors after cleaning.

[0010] Furthermore, the smoke detector moisture-proof testing and research platform simulates various environmental conditions in the field, specifically including: By configuring humidifiers and dust blowing devices, the humidifiers are used to regulate the ambient humidity, and the dust blowing devices simulate dust accumulation conditions, thus constructing multiple sets of simulated on-site environments. The smoke detectors in the test platform were tested in a simulated environment, and the alarm and operating parameters of the detectors were collected in real time using the SystemRead Status function of Verifire Tools. A comparative test was conducted between detectors with and without protective coatings in the same simulated environment to compare their operational stability, number of false alarms, and number of failures. Based on the test results, generate on-site treatment plans for damp locations, and arrange and guide the management and control of damp locations on site.

[0011] Furthermore, the simulated environment includes simulated moisture-proof and dust-proof performance, corrosion-proof performance, enhanced mechanical strength performance, and insulation protection performance.

[0012] Furthermore, a protective coating is applied to the mainboard of the smoke detector at damp locations to prevent short circuits and malfunctions caused by moisture and dust.

[0013] Furthermore, a cold-press cap is installed on the base of the smoke detector to prevent condensation from forming water droplets and to prevent condensation from causing a short circuit in the equipment.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an integrated cleaning and calibration platform, the equipment to be cleaned is located based on data judgment. After cleaning, the equipment threshold calibration and platform simulation test run are performed to avoid secondary false alarms caused by going online directly after cleaning. This solves the technical problem of high false alarm rate and high failure rate of smoke and temperature detectors caused by dust and moisture condensation in subway sites, and extends the service life of the detectors.

[0015] 2.

[0016] 3. The platform pilot application will form feasible solutions for the transformation of existing lines, technical standards for new lines, and maintenance and repair standards for detectors, thereby standardizing and solidifying the results and reducing equipment maintenance and personnel costs.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To address the issue that existing subway station smoke detectors and depot-type aspirating smoke detectors are susceptible to false alarms and equipment damage due to water leakage, condensation, and dust accumulation, and that improvements such as industrial dehumidification and upgrading equipment protection levels have limited effectiveness; furthermore, with increasing operational years, dust and scale buildup on smoke detectors further reduces detection sensitivity and accuracy, this embodiment provides the following technical solution: Please see Figure 1 In this embodiment, the smoke and temperature detector false alarm rectification system cleaning and calibration platform includes: a data and smoke detector cleaning platform, a smoke detector status testing and threshold calibration platform, and a smoke detector moisture-proof testing and research platform.

[0020] The data and smoke detector cleaning platform is configured to monitor the working status of smoke detectors in real time, collect alarm, fault, and shielding data of the detectors, analyze the collected data, determine the critical values ​​of the smoke detectors, and identify detectors that need to be cleaned or replaced.

[0021] The smoke detector status testing and threshold calibration platform is configured to perform data calibration on the smoke detector after cleaning, and connect to the testing platform for performance verification. After passing the verification, it is delivered for field use.

[0022] Specifically, by calling Verifire Tools, entering the Online Services, and retrieving the Detectors option under System Read Status, the corresponding detector point is selected to start reading. After cleaning, the detector threshold is calibrated. The performance verification requires that the detector test value is not greater than 1200, and the detector is considered to be qualified if it runs continuously on the platform for 3 days without any abnormalities.

[0023] Please see Figure 2 The smoke detector moisture-proof testing and research platform is configured to simulate various on-site environmental conditions, test the smoke detectors in the testing platform, compare the changes in alarms, parameters and operational stability of smoke detectors with and without protective coatings under different environments, and output on-site handling solutions for damp locations.

[0024] In this embodiment, the data and smoke detector cleaning platform includes: The cleaning plan generation module is configured to generate corresponding cleaning operation plans based on data analysis results.

[0025] The task management module is configured to allocate and execute cleaning tasks according to the cleaning operation plan, track task progress, and record cleaning results.

[0026] The beneficial effects achieved by the above are as follows: By setting up an integrated cleaning and calibration platform, the equipment to be cleaned is located by data judgment, and the equipment threshold calibration and platform simulation test run are carried out after cleaning, avoiding secondary false alarms caused by going online directly after cleaning; it solves the technical problem of high false alarm rate and high failure rate of smoke and temperature detectors caused by dust and moisture condensation in the subway site, and extends the service life of the detectors.

[0027] In this embodiment, the smoke detection state testing and threshold calibration platform includes: The file management module is configured to create equipment files for smoke detectors, recording the installation location, usage time, and maintenance records of smoke and heat detectors after cleaning.

[0028] The maintenance plan generation module is configured to develop preventative maintenance plans based on equipment usage to reduce equipment failure rates.

[0029] The report statistics module is configured to automatically generate maintenance reports based on cleaning and calibration maintenance operation records.

[0030] The statistical analysis module is configured to perform statistical analysis on the data and output maintenance decisions.

[0031] In this embodiment, the smoke detector moisture-proof testing and research platform simulates various environmental conditions in the field, specifically including: By configuring humidifiers and soot blowing devices, the humidifiers are used to regulate the ambient humidity, and the soot blowing devices simulate dust accumulation conditions, thus constructing multiple sets of simulated on-site environments. The simulated environments include simulated moisture-proof and dust-proof performance, corrosion-proof performance, enhanced mechanical strength performance, and insulation protection performance.

[0032] The smoke detectors in the test platform were tested in a simulated environment, and the alarm and operating parameters of the detectors were collected in real time using the SystemRead Status function of Verifire Tools. Applying a protective coating to the mainboard of smoke detectors in damp locations effectively prevents moisture and dust from affecting the mainboard circuitry, avoiding short circuits and malfunctions caused by moisture and dust. Equipping the smoke detector base with a cold-press cap prevents condensation from forming water droplets, thus preventing short circuits and significantly improving the safety and reliability of the equipment. This protects the electronic components on the mainboard from corrosion caused by environmental chemicals; it also increases the mainboard's mechanical strength, reducing damage from vibration and impact; and provides additional insulation protection to prevent short circuits between circuits.

[0033] A comparative test was conducted by placing detectors with and without protective coatings in the same simulated environment to compare their operational stability, number of false alarms, and number of malfunctions. Based on the test results, an on-site handling plan for damp locations was generated, and on-site management and control of damp locations were arranged and guided.

[0034] Organize test data, develop renovation plans for smoke and temperature detectors at existing line stations, output technical requirements for new lines and incorporate them into new line construction standards; develop maintenance standards for smoke and temperature detectors and update corresponding maintenance procedures.

[0035] The beneficial effects achieved by the above are as follows: By setting up a smoke detector moisture-proof test research platform to conduct comparative simulation tests, the operating status of the equipment under different humidity and dust conditions is obtained, providing experimental support for the on-site protection and treatment of damp locations and avoiding the blind implementation of rectification measures; the combination of protective coating and base cold-press cap effectively inhibits short-circuit damage to the motherboard caused by condensation and dust.

[0036] In this embodiment, six stations on Qingdao Metro Line 3 are used as pilot applications. This line has been in operation for a long time, and the on-site smoke and temperature detectors have a large number of false alarms and equipment failures caused by dust accumulation and condensation.

[0037] The platform includes a data and smoke detector cleaning platform, a smoke detector status testing and threshold calibration platform, and a smoke detector moisture-proof testing and research platform. The data and smoke detector cleaning platform collects alarm, fault, and shielding data of smoke and heat detectors at each site in real time, and uploads the data to the PC for analysis through the Verifire Tools configuration tool to select detectors with thresholds at the critical point as cleaning targets.

[0038] During the operation, grounding defects in the circuit are checked, and abnormal currents are discharged to the ground to avoid damage to equipment due to multiple grounding points. At the same time, the power supply voltage of third-party equipment such as fire dampers and pressurized fans is checked to eliminate the interference of abnormal currents on the system. The platform generates cleaning tasks based on the analysis results, assigns operators, and records the cleaning results of each detector.

[0039] After physical cleaning, the smoke detectors are sent to the smoke detector status testing and threshold calibration platform. The platform creates an electronic file for each detector, recording the installation location, commissioning time, and maintenance records. The Verifire Tools tool is used to read the detector status parameters online and complete the threshold calibration.

[0040] After calibration, the device is connected to the testing platform for performance verification. If the detector reading is ≤1200 and it runs continuously for 3 days without any faults or false alarms, the device is deemed qualified and can be sent to the site for installation and commissioning. The platform automatically generates a complete set of maintenance reports, statistically analyzes false alarms and fault data, and provides a basis for maintenance strategies.

[0041] The smoke detector moisture-proof testing and research platform is also equipped with a humidifier and a dust blowing device to simulate the high humidity and dusty conditions of a subway station. Two sets of comparative prototypes were set up: one with a protective coating on the motherboard and the other without protective treatment. Under the same humidity and dust environment, the detector parameters were continuously read using Verifire Tools, and the number of false alarms and failures of the two sets of prototypes was counted to verify the actual effectiveness of the protective coating in terms of moisture-proof, dust-proof, corrosion-proof, insulation protection, and vibration and shock resistance. The environmental humidity threshold that is prone to triggering false alarms and equipment damage was determined to guide on-site environmental management.

[0042] Actual rectification was carried out at damp locations on site, a protective coating was sprayed onto the mainboard of the detector, and a cold-press cap was added to the base to prevent condensation from causing short circuits; if used in high-temperature areas such as kitchens and restaurants, a rod-shaped constant-temperature detector with a set value of 80℃ can be replaced.

[0043] After the pilot project was completed, the false alarm failure rate of smoke and temperature detectors caused by summer humidity and dust accumulation decreased by 80% compared to before the project. Based on the pilot test results, an upgrade and renovation plan for existing smoke and temperature detectors was developed, technical requirements for new line construction were derived and incorporated into new line standards, smoke and temperature detector maintenance standards were developed, and subway fire protection equipment maintenance procedures were revised. Specific comparative experimental parameters are as follows: ; Table 1. Smoke detector operation data before rectification ; Table 2. Operating values ​​of smoke detectors before calibration after cleaning and applying protective coating. ; Table 3. Smoke Detector Operating Values ​​After Cleaning, Applying Protective Coating, and Calibration ; Table 4. Values ​​of smoke detectors after cleaning, applying protective coating, and calibration, under the influence of dust and moisture. The beneficial effects achieved by the above content are: the pilot application of the platform has formed feasible solutions for the transformation of existing lines, technical standards for new lines, and maintenance and repair standards for detectors, realizing the standardization and solidification of results and reducing equipment maintenance and personnel costs.
