Description

Technical Field

[0001] The present application relates to the technical field of gas alarms, and in particular to a method, system, terminal, and medium for quickly determining an alarm interval of a gas alarm. Background Art

[0002] With the increasing popularity of gas, gas alarms, which are related to its safety, have also become increasingly popular. Gas alarms are used to detect gas concentrations when gas leaks occur. When the gas concentration in the air exceeds the set alarm threshold, an alarm sounds to alert users.

[0003] Despite growing market demand for gas alarms, product quality remains uneven. The use of inferior products poses safety risks, and due to limitations in sensing principles, their lifespans vary. Assessing the quality of these massive quantities of gas alarms has become a pressing issue.

[0004] The actual alarm value (commonly referred to as the alarm action value) of a gas alarm will gradually change and drift over time and due to environmental influences. This change in the alarm action value seriously affects its safety monitoring effectiveness. Typical household gas alarms do not have a specific test concentration display function and only use LED indicators to indicate their operating status, such as normal, fault, and alarm, which are indicated by green, yellow, and red lights, respectively.

[0005] The alarm trigger value of an alarm has a specified testing method in the laboratory. For example, for a natural gas alarm, the method for testing the alarm trigger value is to gradually increase the gas concentration at a rate not exceeding 1%LEL (500ppm) / min. When the alarm sounds, the corresponding gas concentration is recorded. This gas concentration is the product's alarm trigger value.

[0006] Assume the product's actual trigger value is 20%LEL. However, since the tester cannot determine the product's alarm trigger value, and the alarm trigger value will change over time or due to environmental influences, it is necessary to start the test at a lower concentration (for example, 3%LEL). Then, based on the aforementioned gas filling rate, it will take at least 17 minutes to test the product's alarm trigger value. Even if the product's actual trigger value is 10%LEL, it will still take 7 minutes to detect the result.

[0007] For example, home alarms typically require an alarm action value range of 5-25% LEL at the point of use. Therefore, the aforementioned test method typically requires a long test time. Such time-consuming testing is clearly inappropriate for a large number of applications. Summary of the Invention

[0008] In order to achieve rapid detection of the alarm range of a gas alarm at a construction site, thereby improving detection efficiency, the present application provides a method, system, terminal and medium for rapidly determining the alarm range of a gas alarm.

[0009] In the first aspect, the present application provides a method for quickly determining the alarm interval of a gas alarm, using the following technical solutions:

[0010] A method for quickly determining the alarm interval of a gas alarm, comprising:

[0011] Receive gas filling instructions;

[0012] Based on the refueling instruction, jump to the refueling process selection interface; the refueling process selection interface includes a first refueling process option and a second refueling process option, the second refueling process test number is one more than the first refueling process test number, and is at most 5 times; each test lasts for Ts, where Ts is a preset time;

[0013] receiving a first confirmation instruction for the first gas filling process option;

[0014] Based on the first determination instruction, testing the gas alarm preset in the cover according to the first gas filling process to obtain a first alarm value range;

[0015] or,

[0016] receiving a second confirmation instruction for the second refueling process option;

[0017] Based on the second determination instruction, the gas alarm preset in the cover is tested according to the second gas filling process to obtain a second alarm value range.

[0018] By adopting the above technical solution, since the second gas filling process is one more time than the first gas filling process, and at most 5 times, if the first gas filling process needs to be tested 3 times, that is, 3 gas filling concentrations, the second gas filling process needs to be tested 4 times, that is, 4 gas filling concentrations; taking Ts as 50s as an example, since each test lasts 50s, it takes about 3 minutes to 4 minutes to obtain the alarm action interval of the gas alarm; therefore, compared with the method described in the background technology, the test time is greatly saved, and the alarm interval of the gas alarm is quickly detected, thereby improving the detection efficiency; the first gas filling process has fewer tests and takes less time, but the alarm value interval range is large, and the second gas filling process has more tests and takes more time, but the alarm value interval range is smaller and more accurate; the two methods are free for users to choose.

[0019] Optionally, the first gasification process includes the following steps:

[0020] Adding gas into the cover according to a first preset gas concentration value;

[0021] Determine whether the tested gas alarm is in alarm;

[0022] If yes, the subsequent test will add gas into the cover according to the gas concentration value lower than the previous gas concentration value, and continue to determine whether the gas alarm under test alarms;

[0023] If the alarm continues, the test will continue until the preset number of tests is reached; the first alarm value interval is less than the last gas concentration value;

[0024] If no alarm is given, the first alarm value interval is the current gas filling concentration value ~ the previous gas filling concentration value;

[0025] If the gas alarm under test does not sound an alarm during the first test, the subsequent test will add gas into the hood at a higher gas concentration than the previous gas concentration value, and continue to determine whether the gas alarm under test sounds an alarm;

[0026] If yes, then the first alarm value interval is the last gas filling concentration value ~ the current gas filling concentration value;

[0027] If not, continue testing until the preset number of tests is reached; the first alarm value interval is greater than the last gas filling concentration value.

[0028] Optionally, the second gas filling process includes the following steps:

[0029] Adding gas into the cover according to a second preset gas concentration value;

[0030] Determine whether the tested gas alarm is in alarm;

[0031] If yes, the subsequent test will add gas into the cover according to the gas concentration value lower than the previous gas concentration value, and continue to determine whether the gas alarm under test alarms;

[0032] If the alarm continues, the test will continue until the preset number of tests is reached; the initial second alarm value interval is less than the last gas concentration value;

[0033] If no alarm is given, the initial second alarm interval is the current gas concentration value ~ the previous gas concentration value;

[0034] If the gas alarm under test does not sound an alarm during the first test, the subsequent test will add gas into the hood at a higher gas concentration than the previous gas concentration value, and continue to determine whether the gas alarm under test sounds an alarm;

[0035] If yes, the initial second alarm value interval is the last gas filling concentration value ~ the current gas filling concentration value;

[0036] If not, continue testing until the preset number of tests is reached; the initial second alarm value interval is greater than the last gas concentration value;

[0037] Obtaining an average concentration value of the initial second alarm value interval;

[0038] Adding gas into the hood according to the average concentration value, and determining whether the tested gas alarm is in alarm;

[0039] If yes, the final second alarm value interval is the minimum value to the average concentration value of the initial second alarm value interval;

[0040] If not, the final second alarm value interval is the average concentration value to the highest value of the initial second alarm value interval.

[0041] Optionally, after obtaining the first alarm value interval or obtaining the second alarm value interval, the method further includes:

[0042] Obtaining an alarm difference according to the factory alarm setting value corresponding to the detected gas alarm and the first alarm value interval or the second alarm value interval;

[0043] Determining the deviation of the alarm action value according to the alarm difference;

[0044] The interval between the end of the current round of testing and the start of the next round of testing is adjusted according to the deviation.

[0045] By adopting the above technical solution, the larger the alarm difference, the greater the deviation of the alarm action value, which means the worse the product stability, and the interval time can be shortened; the smaller the alarm difference, the smaller the deviation of the alarm action value, which means the better the product stability, and the interval time can be extended; by reasonably determining the inspection cycle of the alarm, manpower is saved and the safety of the gas alarm is ensured.

[0046] Optionally, the method for quickly determining the alarm interval of a gas alarm further includes:

[0047] When the minimum alarm value in the first alarm value interval or the second alarm value interval exceeds the alarm limit value allowed by the tested gas alarm, a deadline replacement reminder message is output.

[0048] By adopting the above technical solution, users can be reminded to make replacements in a timely manner, thereby eliminating safety risks. This saves social costs while ensuring that the gas alarm can serve as a safety alarm.

[0049] Optionally, the method for quickly determining the alarm interval of a gas alarm further includes:

[0050] Obtain the production date of the gas alarm being tested and assign it a value T;

[0051] Get the working time W of the gas alarm under test;

[0052] Obtain the deviation D of the gas alarm under test;

[0053] Based on pre-built quality models , obtain the quality score Q of the gas alarm under test; wherein, is a constant term, The weight assigned to the production date is less than 0, is the weight of working hours and is less than 0, is the weight of the deviation and is greater than 0.

[0054] By adopting the above technical solution, the larger the quality score Q is, the better the quality of the gas alarm is.

[0055] Secondly, the present application provides a system for quickly determining the alarm interval of a gas alarm, which adopts the following technical solutions:

[0056] A system for quickly determining the alarm interval of a gas alarm, comprising:

[0057] An instruction receiving module, configured to receive a gas filling instruction, a first confirmation instruction for a first gas filling process option, and a second confirmation instruction for a second gas filling process option;

[0058] An interface jump module is used to jump to a gas filling process selection interface based on the gas filling instruction; the gas filling process selection interface includes the first gas filling process option and the second gas filling process option, the second gas filling process is tested once more than the first gas filling process, and is at most 5 times; each test lasts for Ts, where Ts is a preset time;

[0059] an alarm processing module, configured to test the gas alarm disposed in the housing according to the first gas filling process based on the first determination instruction to obtain a first alarm value interval;

[0060] Alternatively, the alarm processing module is configured to test the gas alarm disposed in the cover body according to the second gas filling process based on the second determination instruction to obtain a second alarm value range.

[0061] By adopting the above technical solution, since the second gas filling process is one more time than the first gas filling process, and at most 5 times, if the first gas filling process needs to be tested 3 times, that is, 3 gas filling concentrations, the second gas filling process needs to be tested 4 times, that is, 4 gas filling concentrations; taking Ts as 50s as an example, since each test lasts 50s, it takes about 3 minutes to 4 minutes to obtain the alarm action range of the gas alarm; therefore, compared with the method described in the background technology, it greatly saves test time, realizes rapid detection of the alarm range of the gas alarm, thereby improving detection efficiency; the first gas filling process has fewer tests and takes less time, but the alarm value range is large, the second gas filling process has more tests and takes more time, but the alarm value range is smaller and more accurate.

[0062] In a third aspect, the present application provides a terminal that adopts the following technical solution:

[0063] A terminal, comprising:

[0064] A memory storing the above-mentioned program for quickly determining the alarm interval of the gas alarm;

[0069] A portable detection device is embedded with the above-mentioned system for quickly judging the alarm range of a gas alarm, and can be connected to an external gas filling device to control the operation of the external gas filling device.

[0070] In summary, this application has at least the following beneficial effects:

[0071] 1. Set a first gas filling process and a second gas filling process for selection, and the test number of the second gas filling process is one more than the test number of the first gas filling process, and at most 5 times; the purpose of each test lasting Ts is to obtain the alarm action range of the gas alarm in a shorter time; therefore, compared with the method described in the background technology, it greatly saves test time, realizes rapid detection of the alarm range of the gas alarm, and thus improves detection efficiency; the first gas filling process has fewer tests and takes less time, but the alarm value range is large, the second gas filling process has more tests and takes more time, but the alarm value range is smaller and more accurate; and the two methods are free for users to choose.

[0072] 2. The purpose of obtaining the alarm difference and determining the deviation of the alarm action value is that the larger the alarm difference, the greater the deviation of the alarm action value, which means the product stability is worse, so it is necessary to shorten the interval and increase the detection frequency; the smaller the alarm difference, the smaller the deviation of the alarm action value, which means the product stability is better, so it is necessary to extend the interval and reduce the detection frequency; by reasonably determining the inspection cycle of the alarm, it saves manpower and ensures the safety of the gas alarm.

[0073] 3. The purpose of obtaining the quality score value Q is that the larger the score value Q is, the better the quality of the gas alarm is, and the production quality of the manufacturer can be evaluated. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1 ~Attachment Figure 8 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0084] Although at the engineering site, the best result is to be able to detect the specific action value of the gas alarm (accurate to 1%LEL), so as to facilitate further judgment of product quality and whether it meets the requirements of on-site application; however, from the perspective of engineering site application, it is not necessary to accurately know the specific alarm action value.

[0085] For example, relevant standards stipulate that as long as the alarm value of a gas alarm is within the range of 5%LEL to 25%LEL, it can function as a leak alarm. If a user wishes for a more sensitive gas alarm, the alarm value range can be appropriately lowered, for example, to between 5%LEL and 10%LEL. If the user wishes for a slightly slower alarm, the alarm value range can be appropriately increased, for example, to between 10%LEL and 20%LEL. As long as the adjusted alarm value range is within the range of 5%LEL to 25%LEL, it can function as an effective alarm.

[0086] If the gas alarm's alarm value can be determined to be within a certain range on-site, it will save on-site testing time. For example, if the alarm action value of a gas alarm is between 8%LEL and 10%LEL, or between 12%LEL and 15%LEL, it is sufficient to determine whether the gas alarm meets the requirements of the project site application. Based on the tested alarm range, combined with the gas alarm's factory alarm setting, the quality of the gas alarm can be further evaluated, thereby inferring future application trends and determining the next inspection cycle time, thereby reasonably reducing social resources and ensuring that the gas alarm can perform its safety monitoring function during this period.

[0087] Therefore, in order to quickly determine the alarm interval of the gas alarm, the first embodiment of the present application discloses a method for quickly determining the alarm interval of the gas alarm. Figure 1As an embodiment of the method for quickly determining the alarm interval of a gas alarm, the method for quickly determining the alarm interval of a gas alarm may include S110 to S140, or S110 to S120 and S150 to S160:

[0088] S110, receiving a gas filling instruction;

[0089] S120, based on the gas filling instruction, jump to the gas filling process selection interface; the gas filling process selection interface includes a first gas filling process option and a second gas filling process option;

[0090] S130, receiving a first confirmation instruction for a first gas filling process option;

[0091] S140: Based on the first determination instruction, the gas alarm preset in the cover is tested according to the first gas filling process to obtain a first alarm value range.

[0092] or,

[0093] S150, receiving a second confirmation instruction for a second gas filling process option;

[0094] S160: Based on the second determination instruction, the gas alarm preset in the cover is tested according to the second gas filling process to obtain a second alarm value range.

[0095] Specifically, the second refueling process is tested one more time per round than the first, up to a maximum of five times. Each test lasts for a preset duration, Ts, which can be set by the tester based on actual conditions. To obtain a more precise alarm threshold, increase the number of tests per round.

[0096] Reference Figure 2 The first gas filling process may include steps S201 to S210:

[0097] S201, adding gas into the housing according to a first preset gas concentration value;

[0098] S202, determining whether the gas alarm under test is in alarm;

[0099] S203, if yes, then the subsequent test adds gas into the housing according to a gas concentration value lower than the previous gas concentration value, and continues to determine whether the tested gas alarm sounds an alarm;

[0100] S204, if yes, continue testing until the preset number of tests is reached;

[0101] S205, the first alarm value interval is less than the last gas filling concentration value;

[0102] S206, if not, the first alarm value interval is the current gas concentration value ~ the previous gas concentration value;

[0103] S207, if the gas alarm under test does not sound an alarm after S201, then the subsequent test adds gas into the cover at a gas concentration value higher than the previous gas concentration value, and continues to determine whether the gas alarm under test sounds an alarm;

[0104] S208, if yes, the first alarm value range is from the last gas filling concentration value to the current gas filling concentration value;

[0105] S209, if not, continue testing until the preset number of tests is reached;

[0106] S210: The first alarm value interval is greater than the last gas filling concentration value.

[0107] For example, the first gas filling process has three test processes and Ts is 50s. 50s is the test duration determined based on historical gas alarm test results. For example, if the first preset gas concentration is 11%LEL, then during the first test, 11%LEL gas is added to the hood, and then a determination is made within 50s whether the gas alarm sounds.

[0108] If so, add 7%LEL of gas into the hood for the second time, and continue to judge whether the gas alarm alarms within 50S. If not, the first alarm value range is 7%LEL~11%LEL. If so, add 3%LEL of gas into the hood for the third time, and continue to judge whether the gas alarm alarms within 50S. If not, the first alarm value range is 3%LEL~7%LEL. If so, the first alarm value range is less than 3%LEL.

[0109] If not, add 15%LEL of gas into the hood for the second time, and continue to judge whether the gas alarm alarms within 50S. If so, the first alarm value interval is 11%LEL~15%LEL. If not, add 20%LEL of gas into the hood for the third time, and continue to judge whether the gas alarm alarms within 50S. If so, the first alarm value interval is 15%LEL~20%LEL. If not, the first alarm value interval is greater than 20%LEL.

[0110] Reference Figure 3 and Figure 4 The second gas filling process includes steps S301 to S314:

[0111] S301, adding gas into the cover according to a second preset gas concentration value;

[0112] S302, determining whether the gas alarm under test is in alarm;

[0113] S303, if yes, then the subsequent test adds gas into the housing according to a gas concentration value lower than the previous gas concentration value, and continues to determine whether the tested gas alarm alarms;

[0114] S304, if yes, continue testing until the preset number of tests is reached;

[0115] S305, the initial second alarm value interval is less than the last gas filling concentration value;

[0116] S306, if not, the initial second alarm interval is the current gas filling concentration value ~ the previous gas filling concentration value;

[0117] S307, if the gas alarm under test does not sound an alarm after S301, then the subsequent test adds gas into the cover at a gas concentration value higher than the previous gas concentration value, and continues to determine whether the gas alarm under test sounds an alarm;

[0118] S308: If yes, the initial second alarm value range is from the last gas filling concentration value to the current gas filling concentration value;

[0119] S309, if not, continue testing until the preset number of tests is reached;

[0120] S310, the initial second alarm value interval is greater than the last gas filling concentration value;

[0121] S311, obtaining the average concentration value of the initial second alarm value interval;

[0122] S312, adding gas into the hood according to the average concentration value, and determining whether the gas alarm under test is alarming;

[0123] S313: If yes, the final second alarm value interval is the minimum value to the average concentration value of the initial second alarm value interval;

[0124] S314: If not, the final second alarm value interval is the average concentration value to the highest value of the initial second alarm value interval.

[0125] If the first gas filling process has three test processes, the second gas filling process has four test processes. For example, if the second preset gas concentration value is 15%LEL, then in the first test, 15%LEL gas is added to the hood, and then the gas alarm is judged within 50 seconds to see if it sounds.

[0126] If so, add 10%LEL of gas into the hood for the second time, and continue to judge whether the gas alarm alarms within 50S. If not, the initial second alarm value range is 10%LEL~15%LEL. If so, add 5%LEL of gas into the hood for the third time, and continue to judge whether the gas alarm alarms within 50S. If not, the initial second alarm value range is 5%LEL~10%LEL. If so, the initial second alarm value range is less than 5%LEL.

[0127] If not, add 20%LEL of gas into the hood for the second time, and continue to judge whether the gas alarm alarms within 50S. If so, the initial second alarm value range is 15%LEL~20%LEL. If not, add 25%LEL of gas into the hood for the third time, and continue to judge whether the gas alarm alarms within 50S. If so, the initial second alarm value range is 20%LEL~25%LEL. If not, the initial second alarm value range is greater than 25%LEL.

[0128] After completing steps S301 to S310, if the initial second alarm value interval is 10%LEL~15%LEL, the average concentration value of the initial second alarm value interval is 12.5%LEL, and 12.5%LEL of gas is added to the hood for the fourth time to determine whether the gas alarm alarms within 50S. If so, the final second alarm value interval is 10%LEL~12.5%LEL. If not, the final second alarm value interval is 12.5%LEL~15%LEL.

[0129] It should be noted that for the first and second gasification processes, the first and second preset gasification concentration values ​​can be the same or different, and the parameters can be edited. The steps in the second gasification process before obtaining the average concentration value can be the same as those in the first gasification process. In this case, the second gasification process can be regarded as an additional execution of steps S307 to S310 for the first alarm value range.

[0130] Furthermore, when the minimum alarm value in the first alarm value interval or the second alarm value interval exceeds the alarm limit value allowed by the tested gas alarm, a deadline replacement reminder message is output.

[0131] Taking the second alarm value interval as an example, if the second alarm value interval is greater than 25%LEL and the alarm limit value is 25%LEL, the user can be prompted to replace it within a preset period, for example, the preset period can be 5 days, and the preset period can be set.

[0132] Reference Figure 5 As another embodiment of the method for quickly determining the alarm interval of a gas alarm, the method for quickly determining the alarm interval of a gas alarm may further include S510 to S530:

[0133] S510, obtaining an alarm difference value according to the factory alarm setting value and the first alarm value interval or the second alarm value interval corresponding to the detected gas alarm;

[0134] S520, determining the deviation of the alarm action value according to the alarm difference;

[0135] S530: Adjust the interval between the end of the current round of testing and the start of the next round of testing according to the deviation.

[0136] Specifically, the alarm difference can be understood as the difference between the middle value of the first alarm value interval or the second alarm value interval and the alarm factory setting value, and then the absolute value is taken; the larger the alarm difference, the greater the deviation of the alarm action value, which means the product stability is worse, so it is necessary to shorten the interval from this round to the next round of testing; the smaller the alarm difference, the smaller the deviation of the alarm action value, which means the product stability is better, so it is necessary to extend the interval from this round to the next round of testing.

[0137] For example, the factory setting value of the gas alarm under test is 8%LEL. Taking the first alarm value range as an example, after the first round of testing, if the first alarm value range is 7%LEL~11%LEL, the middle value is 9%LEL, and the alarm difference is |9%LEL-8%LEL|=1%LEL; since the alarm difference is less than the preset alarm difference threshold of 5%, it indicates that the deviation is small, so the interval time from this round to the next round of testing can be extended.

[0138] Further, refer to Figure 6 The method for quickly determining the alarm interval of a gas alarm further includes S610 to S640:

[0139] S610, obtaining the production date of the gas alarm under test and assigning a value T;

[0140] S620, obtaining the working time W of the gas alarm under test;

[0141] S630, obtaining the deviation D of the gas alarm under test;

[0142] S640, based on pre-built quality models , obtain the quality score Q of the tested gas alarm.

[0143] Specifically, is a constant term, The weight assigned to the production date is less than 0, is the weight of working hours and is less than 0, is the weight of the deviation and is greater than 0; the deviation D can be represented by the alarm difference. The larger the quality score Q, the better the quality of the gas alarm.

[0144] Regarding the assignment of production date: take a certain production date as the basis and set the assignment value to 0. Then, for every year the production date is advanced, the assignment value will increase by 1. The assignment value can be modified and edited through the background.

[0145] The implementation principle of this embodiment is:

[0146] Receive the gas filling instruction, jump to the gas filling process selection interface, receive the first confirmation instruction, add 11%LEL of gas into the cover for the first time, and then judge whether the gas alarm alarms within Ts. If so, add 7%LEL of gas into the cover for the second time, and continue to judge whether the gas alarm alarms within Ts. If so, add 3%LEL of gas into the cover for the third time, and continue to judge whether the gas alarm alarms within Ts. If not, the first alarm value range is 3%LEL to 7%LEL;

[0147] Furthermore, the alarm difference of this round can be obtained based on the alarm factory setting value. If the alarm difference is relatively large, the interval between this round and the next round of testing can be shortened and the next round of testing can be carried out as soon as possible.

[0148] Based on the above method embodiment, the second embodiment of the present application discloses a system for quickly determining the alarm interval of a gas alarm.
