[0027] As described in the background art section, the power industry is the main force in energy security and shoulders the important mission of implementing energy security. The underground powerhouse space of pumped-storage power stations in the power industry is relatively enclosed and the cable laying is relatively concentrated, forming a cable interlayer. The fire hazards therein pose a serious threat to the safe operation of the power grid and the safe production of electric power. The structure of the underground powerhouse of a pumped-storage power station is complex and the ventilation is limited. Once an electrical fire occurs, the fire spreads rapidly and it is difficult for on-site personnel to escape. Therefore, the power station has an urgent market demand for sensitive and efficient fire detection technologies.
[0028] Currently, the fire protection technologies for pumped-storage power stations include smoke sensors, temperature sensors, flame detectors, etc. Although the above fire protection technologies can reduce the losses caused by fire accidents, however, the above fire protection technologies are mainly for post-fire warning, and there is a lag in fire warning, which cannot suppress the development of the fire in advance and cannot fundamentally avoid the occurrence of fire accidents.
[0029] In view of this, an embodiment of the present application proposes a warning method based on pyrolysis particles, referring to Figure 1 , applied to a cable interlayer, the cable interlayer includes a plurality of substance detectors, and the method includes the following steps:
[0030] Step 101: For each substance detector, in response to determining that the detection function of the substance detector is normal, obtain the environmental substances in the cable interlayer through the substance detector.
[0031] In this step, the cable interlayer refers to the structural layer specifically set under the control room or electrical distribution room for laying cables required for instruments, control devices, etc. entering the control room and electronic equipment room. The cable interlayer has a relatively large number of cables, and once a fire occurs, relatively serious consequences will occur. Therefore, it is very necessary to provide early warning for cable interlayer fires. As Figure 2 shown, the thermal breakdown point and ignition point of objects of the same material are different, and the thermal breakdown point of an object of the same material is less than the thermal ignition point of the object. Therefore, the object reaches the thermal breakdown point first and then the ignition point. After the object is heated to the thermal breakdown point, it will decompose to obtain relatively microscopic substances, which are earlier than the generation of smoke after the object reaches the ignition point. For example, the relatively microscopic substances are invisible pyrolysis particles of 2 - 10 nanometers. Substance detectors are more sensitive than traditional detectors such as smoke detectors, temperature detectors, and flame detectors.
[0032] As Figure 3 shown, in the case of a relatively large fire, traditional detectors can detect a relatively large smoke concentration, while in the case of no open fire, the substance detector can already capture the pyrolysis particles obtained by thermal decomposition. Through the detection of pyrolysis particles, the purpose of early fire warning can be achieved. By capturing and processing substances, early fire perception can be realized during the heating stage of the object, that is, it can be sensed in advance whether a fire will occur before the open fire appears, and then corresponding measures can be taken to eliminate the harm caused by the open fire and ensure the safety of the cable interlayer. A substance detector is a device used to detect and analyze substances and can detect these decomposed substances. Exemplarily, the substance detector is a pyrolysis particle detector and a dual - detection pyrolysis particle detector. The pyrolysis particle detector can detect the pyrolysis particles (invisible particles) released by the cable when heated in the earliest stage of a fire, achieving early perception. In addition to detecting pyrolysis particles, the dual - detection pyrolysis particle detector can also detect other substances, such as PM2.5. In addition, the substance detector has good compatibility and expandability, can be integrated with the existing fire warning system in the cable interlayer, and realizes lean management of the whole process from ultra - early fire warning to mid - to - late - stage fire source location and investigation, providing all - round services for the fire safety prevention and control of the underground powerhouse of the pumped - storage power station.
[0033] Particles can be detected by a substance detector. Therefore, multiple substance detectors are installed in the cable interlayer. For the stability of the substance detector, the substance detector is installed on a load-bearing wall. For example, the bottom edge is 1.5 meters from the ground. During the installation of the substance detector, dust and other impurities generated may affect the sensitivity of the substance detector and installation errors may also occur. Therefore, it is necessary to detect the function of the substance detector to ensure that the substance detector is in a normal working state. When the detection function of the substance detector is normal, the environmental substances in the cable interlayer are obtained through the substance detector.
[0034] Step 102: Perform a purification operation on the environmental substances to obtain target environmental substances.
[0035] In this step, the environmental substances are distributed in the cable interlayer space and may be accompanied by impurities such as dust. If the environmental substances are directly analyzed, it will affect the accuracy of the analysis of the environmental substances. Therefore, it is necessary to perform a purification operation on the environmental substances to obtain target environmental substances, removing the interference factors in the environmental substances and achieving the purpose of purifying the environmental substances.
[0036] Step 103: Perform a concentration analysis on the target environmental substances to obtain the concentration of at least one substance in the target environmental substances.
[0037] In this step, substances are generated when an object decomposes by heat. The greater the concentration of the substances, the greater the degree of heat the object has received; the smaller the concentration of the substances, it indicates that the object may not have decomposed by heat. Therefore, it is necessary to perform a concentration analysis on the target environmental substances to obtain the concentration of at least one substance in the target environmental substances. By performing a concentration analysis on the target environmental substances, it is possible to accurately determine whether the object in the cable interlayer has decomposed by heat.
[0038] Step 104: Based on the concentration of at least one substance, determine whether a fire has occurred in the cable interlayer.
[0039] In this step, the substance concentration can reflect whether the object in the cable interlayer has decomposed by heat. When the substance concentration is relatively high, it indicates that the object has decomposed by heat, and then it is possible to determine whether a fire has occurred in the cable interlayer. It should be noted that the above-mentioned fire refers to the ultra-early stage of the fire, that is, the stage of the fire without open flames. At this time, the object reaches the thermal breakdown point but not the ignition point. The substances generated by the decomposition of the object by heat precede the fire smoke, and then by analyzing the substance concentration, it is possible to timely determine whether a fire has occurred in the cable interlayer, achieving the purpose of determining whether a fire has occurred in the cable interlayer in advance.
[0040] Step 105: In response to determining that a fire has occurred in the cable interlayer, generate and send a fire warning message based on the installation information corresponding to the substance detector.
[0041] In this step, when it is determined that a fire has occurred in the cable interlayer, fire warning information is generated and sent based on the installation information of the material detector. When the cable interlayer is relatively large, the number of material detectors in the cable interlayer is relatively large. Generating and sending fire warning information based on the installation information can facilitate users to promptly determine which material detector issued the fire warning, and then promptly check the space where the material detector is located. Sending fire warning information before an open flame appears allows users to promptly learn of a fire in the cable interlayer, and then take appropriate rescue measures to reduce the harm caused by the fire.
[0042] Through the advanced fire warning technology of this application, precious rescue time is gained for on-site fire handling, the development of the fire is prevented from causing damage to on-site equipment and personnel, the fire safety prevention and control capabilities in closed places with dense cable laying are improved, and the further expansion of the fire is effectively prevented, providing strong guarantees for the safe operation of the power grid and on-site safety production. At the same time, it can provide all-round fire information to help operation and maintenance personnel deal with on-site fires in a timely manner. Its application in semi-enclosed places with dense cable laying has improved the lean management level of safety production in the power industry and strengthened the industry's inherent safety capacity building.
[0043] It should be noted that excessive heating of various cables, switch cabinets, battery packs, transformer equipment, etc. can also produce substances. The advanced fire warning technology of this application can be extended to fire monitoring applications in closed rooms such as high-voltage switch cabinets, cable trenches, cable mezzanines, cable shafts, cable tunnels, battery rooms, and main transformer rooms.
[0044] Through the above scheme, for each material detector, in response to determining that the detection function of the material detector is normal, the environmental material in the cable interlayer is obtained through the material detector. The environmental material is purified to obtain the target environmental material, and the interference factors in the environmental material are removed, so as to achieve the purpose of purifying the environmental material. The target environmental material is analyzed for concentration to obtain the concentration of at least one substance in the target environmental material. By analyzing the concentration of the target environmental material, it is possible to accurately determine whether the object in the cable interlayer is decomposed by heat. Based on the concentration of at least one substance, it is determined whether the cable interlayer has a fire, and it is possible to determine whether the cable interlayer has a fire in time, so as to achieve the purpose of determining in advance whether the cable interlayer has a fire. In response to determining that the cable interlayer has a fire, a fire warning message is generated and sent based on the installation information corresponding to the material detector. The fire warning message is sent before the open fire appears, so that the user can be informed of the fire in the cable interlayer in time, and then take corresponding rescue measures to reduce the harm caused by the fire.
[0045] In some embodiments, determining whether a fire has occurred in the cable interlayer based on the concentration of the at least one substance includes: calculating a weighted value of the concentration of the at least one substance according to a predetermined weight corresponding to each substance concentration to obtain a total substance concentration; and determining that a fire has occurred in the cable interlayer in response to determining that the total substance concentration is greater than a predetermined concentration.
[0046] In this embodiment, predetermined weights are set for all substances that may be generated after the object is thermally decomposed. Exemplarily, the above substances include pyrolysis particles and PM2.5. The predetermined weights are set according to historical experience. Since the concentration of pyrolysis particles can more accurately reflect whether the object has undergone thermal decomposition, a relatively large predetermined weight needs to be set for the concentration of pyrolysis particles. Calculate a weighted value of the concentration of at least one substance according to the predetermined weight corresponding to each substance concentration to obtain a total substance concentration. When the total substance concentration is greater than the predetermined concentration, it indicates that the total substance concentration is relatively large and the object has undergone thermal decomposition. Therefore, it is determined that a fire has occurred in the cable interlayer, where the predetermined concentration is determined according to historical experience. By comparing the numerical values of the total substance concentration and the predetermined concentration, the purpose of accurately determining whether a fire has occurred in the cable interlayer is achieved.
[0047] In some embodiments, the installation information corresponding to the substance detector includes the installation position; generating and sending a fire warning message based on the installation information corresponding to the substance detector includes: generating a fire warning message including the installation position based on the installation information; and pushing the fire warning message to a predetermined receiving end.
[0048] In this embodiment, when the cable interlayer is relatively large, a relatively large number of substance detectors need to be installed. In order to accurately determine which substance detector detected the environmental substances and generated the fire warning message, a fire warning message including the installation position of the substance detector needs to be generated. Push the fire warning message to a predetermined receiving end, where the predetermined receiving end may be a fixed device receiving end. Figure 4 This is a schematic diagram of the warning interface of the fixed device receiving end of the embodiment of the present application. For example, a computer receiving end; the predetermined receiving end may also be a mobile device receiving end. Figure 5 This is a schematic diagram of the warning interface of the mobile device receiving end of the embodiment of the present application. For example, a mobile phone receiving end. The fire warning message received by the mobile phone receiving end can be received through a predetermined small program in the mobile phone. Through the fire warning message displayed by the predetermined receiving end, relevant personnel can handle it in time, reducing the harm caused by the fire and eliminating the fire hazard in the bud. Fire warning is carried out before the open fire appears, minimizing the loss or even making the loss zero, thereby fundamentally eliminating the fire hazard, effectively suppressing the occurrence of major and extremely serious fire accidents, and improving the operation stability of the equipment and enhancing the reliability of the power plant operation.
[0049] It should be noted that the installation information may also include the number or name of the material detector, and the above installation information also has the function of enabling relevant personnel to promptly know the location of the material detector that issued the warning. In order for on-site personnel to intuitively view and operate the equipment information in the cable interlayer, an intelligent display screen may be set in the cable interlayer, and the display content includes the status information, alarm information, monitoring data, operation options, etc. of the material detector, to ensure that the equipment information can be easily viewed and used by on-site personnel.
[0050] In some embodiments, the purifying operation on the environmental substance to obtain the target environmental substance includes: humidifying and reducing the pressure on the environmental substance to obtain the target environmental substance.
[0051] In this embodiment, if Figure 6 As shown in the figure, the collected environmental substances are humidified to effectively filter out dust and other particulate matter in the air, and eliminate the interference of pollutants other than combustion smoke on the equipment. At the same time, the environmental substances are depressurized to make the environmental substances evenly distributed. If unevenly distributed environmental substances are used for processing, the accuracy of the processing results will be affected. By humidifying and depressurizing the environmental substances, the interference of external factors on the environmental substances is eliminated, and the problem of false fire alarms is solved.
[0052] In some embodiments, determining that the detection function of the material detector is normal includes: performing an electrical connection check on the material detector; in response to determining that the material detector passes the electrical connection check, performing a fire simulation test and a non-smoke simulation test in the cable interlayer; in response to determining that the material detector passes the fire simulation test and the non-smoke simulation test, determining that the detection function of the material detector is normal.
[0053] In this embodiment, the material detector is subjected to an electrical connection check, and the inspection items include power supply and connection tests. When the power supply is normal and the connection line is open, it means that the material detector has passed the electrical connection check. When the material detector passes the electrical connection check, a fire simulation test and a non-smoke simulation test are performed in the cable interlayer. The fire simulation test includes an airflow test, an airflow stability test, a pyrolytic particle and smoke detection test, a sensitivity test, a response time test, and an alarm mode evaluation test. The airflow test needs to test the operation of the suction pump airflow device of the material detector. When the suction pump airflow device can stably and normally introduce air, it means that the material detector has passed the airflow test. The airflow stability test needs to verify whether the introduced air is stable. When the air introduced by the suction pump airflow device is stable, it means that the material detector has passed the airflow stability test. The pyrolytic particle and smoke detection test needs to test whether the material detector can detect abnormalities. The sensitivity test needs to test the triggering time and accuracy of the material detector under different concentrations of smoke. When the material detector shows good sensitivity to different concentrations of pyrolytic particles and smoke and triggers the alarm within a reasonable time, it means that the material detector has passed the sensitivity test. The response time test needs to record the time from when the material detector detects smoke to when the alarm is triggered. If the material detector responds and triggers the alarm within the specified time range, it means that the material detector has passed the response time test.
[0054] The non-smoke simulation test includes arc generator test, false alarm rate evaluation test, environmental adaptability test and environmental interference test. The arc generator test simulates the arc fog situation. If the material detector can quickly and accurately detect the smoke and trigger the alarm, it means that the material detector has passed the arc generator test. The false alarm rate evaluation test simulates the non-smoke situation to observe whether there will be false alarms. If the material detector shows good stability and low false alarm rate under non-smoke conditions, it means that the material detector has passed the false alarm rate evaluation test. The environmental adaptability test tests the performance of the material detector under different temperature and humidity conditions. If the material detector shows stable performance in a wide range of temperature and humidity, it means that the material detector has passed the environmental adaptability test. The environmental interference test observes whether other factors (such as steam) will interfere with the performance of the material detector. If the material test detector is not easily interfered in a general indoor environment, it means that the material detector has passed the environmental interference test. By conducting a variety of tests on the material detector, the accuracy of verifying the function of the material detector is ensured.
[0055] It should be noted that an alarm mode evaluation test and a pre-warning test for the system and the mobile phone can also be carried out. For the alarm mode evaluation test, the effectiveness of alarm modes such as the sound and light flashing used when the detector triggers an alarm needs to be checked. When the alarm mode is obvious and can attract people's attention, it indicates that the alarm mode evaluation test is passed. When the system passes the test and can send pre-warning information in a timely manner, it indicates that the pre-warning test for the system and the mobile phone is passed.
[0056] In some embodiments, the method further includes: in response to determining that the substance detector fails the electrical connection check, generating and sending first maintenance information corresponding to the substance detector; or, in response to determining that the substance detector fails the fire simulation test and / or the non-smoke simulation test, generating and sending second maintenance information corresponding to the substance detector.
[0057] In this embodiment, when the substance detector fails the electrical connection check, it indicates that there is a problem with the electrical connection of the substance detector and the substance detector needs to be repaired. Therefore, first maintenance information corresponding to the substance detector is generated and sent, where the first maintenance information is used to characterize the electrical connection fault information. Or, when the substance detector passes the electrical connection check but fails the fire simulation test and / or the non-smoke simulation test, second maintenance information corresponding to the substance detector is generated and sent, where the second maintenance information is used to characterize the information that the simulation test fails. It should be added that both the generated first maintenance information and the generated second maintenance information include the installation position of the substance detector. By sending the maintenance information for the substance detector, it is ensured that the substance detector can be repaired in a timely manner.
[0058] In some embodiments, the at least one substance concentration at least includes the concentration of pyrolysis particles.
[0059] In this embodiment, pyrolysis particles refer to tiny particulate matter generated by the thermal decomposition of solid or liquid materials at high temperatures. The diameters of these particles are generally between 1 micron and 100 microns, with irregular shapes, and variable colors and morphologies. In a fire, as the temperature rises, the molecular bonds of the substance break and pyrolysis particles are released. Different from smoke particles, pyrolysis particles are not easily dispersed by a fan and have the characteristic of wind interference resistance. Therefore, in this embodiment, they are used for ultra-early fire detection and warning. Fire warning through pyrolysis particles greatly improves the fire prevention of cable galleries, including accurate and reliable fire detection. Compared with traditional fire alarms, the fire warning based on pyrolysis particles can achieve early warning, can detect the extremely early hidden dangers of a fire in the first place, effectively prevent the further spread of the fire, and the fire warning information is pushed in a timely and efficient manner.
[0060] In another embodiment provided by the present application, the pipeline connection of the substance detector adopts a flame-retardant ABS (Acrylonitrile Butadiene Styrene) special fire detector air sampling pipe to ensure reasonable pipeline installation, tight pipeline connection, no air leakage, and no blockage. Smoke is introduced from the sampling hole at the very end (the most unfavorable position) of the sampling pipe. The maximum allowable smoke transmission time for each substance suction detector should not exceed 120 s. The detector of the early warning system adopts an ABS special fire detector air sampling pipe, which can be arranged in a relatively narrow passage, has a wide application range, and has no false alarms. During the equipment installation and commissioning stage, the sensitivity and alarm threshold of the detector terminal have been reasonably set to completely solve the false alarm situation and completely avoid false alarms caused by pollutants other than smoke.
[0061] According to the on-site situation, corresponding parameters of the substance detector are configured, such as detection sensitivity, alarm value, etc. Conduct linkage tests with the fire main controller to ensure normal cooperation with the fire main controller system. Set obvious signs at appropriate positions for convenient future maintenance and management. Ensure that the early warning system is installed qualified, complies with relevant standards and specifications, and follows relevant codes and fire protection standards. The sampling pipe adopts a flame-retardant ABS special fire detector air sampling pipe with an outer diameter of 25 mm and an inner diameter of 21 mm. The sampling pipe uses straight-through connections, and each joint is sealed with special glue to ensure no blockage and no air leakage. The sampling pipe is fixed with pipe clamps to ensure that it can firmly fix the sampling pipe without causing damage to the pipeline, so that the sampling pipe can be stressed smoothly during the entire fixing process without sagging or bending. A spirit level is used during the fixing process to ensure that the sampling pipe is horizontal and vertical, avoiding unevenness or skew during the installation process. Effectively ensure that the sampling pipe is firmly fixed, clean and beautiful, without affecting the later maintenance of existing equipment.
[0062] The sampling hole uses a special ABS flame-retardant and dust-proof sampling hole with a special sampling identification sticker. The 2.5mm sampling hole is small in size and can be used for accurate environmental collection. It is suitable for high-precision sampling applications. The ABS pipe has high wear resistance and impact resistance and is not easily damaged during long-term use. The advantages of the 2.5mm sampling hole are accurate sampling, good dustproof effect, and strong durability, which helps to maintain the stability of the pipeline system. The use of flame-retardant large-curvature elbows at the bends can ensure air circulation during air sampling. The flame-retardant large-curvature elbows can change the direction of air flow, so that the air can flow smoothly through the elbows during the sampling process without causing fluid blockage or blockage. This can maintain air circulation at the sampling point, ensure that the collected air samples are real and representative, and avoid deviations in sampling results due to fluid blockage. Paste the identification sticker on the top of the pipeline to ensure that it is easy for staff to see and identify. Paste the identification sticker at the sampling point and in obvious places to facilitate staff to understand the direction of the pipeline. Use obvious and eye-catching yellow to mark the pipeline to reduce operating errors. Graphic identification: Adding simple and easy-to-understand digital graphics to the identification sticker can increase the intuitiveness and recognition of the label. The label is made of weather-resistant material to ensure that the label will not fade or peel off after long-term use. Maintain the readability and effectiveness of the label. Improve operational efficiency by improving pipeline label.
[0063] In another embodiment provided by the present application, the material detector is a highly sensitive detection device. Therefore, before and during construction, it should be properly stored and kept clean, and prohibited from contact with water, dust, etc., and protective measures should be taken before acceptance. The installation steps of the material detector include:
[0064] 1. Before the air sampling tube is installed into the air inlet of the material detector, the end should be sealed to prevent dust and other debris from entering.
[0065] 2. When installing the material detector, do not open the plug on the detector's air inlet before installing the sampling tube.
[0066] 3. During the debugging and operation of the material detector, if a temporary power supply is used, the battery cannot be connected to the device to prevent the main power supply from failing and causing the battery to be over-discharged and damaged. The test personnel used a hot air gun to heat the cable samples at different locations in the cable interlayer fire monitoring area. The system issued a fire warning in the test area within 6 minutes, and the smoke detection device in the area did not alarm during the same period. The device test results prove that the system detects the fire hazard of cable overheating earlier than the smoke monitoring device.
