This invention solution can effectively utilize the data during the normal operation of gas equipment to improve the effectiveness of gas equipment management, and helps to determine a reasonable gas equipment maintenance plan and maintenance schedule;

[0003] However, in the specific application process of the above invention solution, it is impossible to reasonably judge the start-up risk of gas equipment before starting, and it is difficult to conduct progressive and accurate assessment and timely warning of the gas transmission status and the environmental risks during the operation of gas equipment, which is not conducive to improving the use safety of gas equipment and reducing the user management difficulty, and the level of intelligence and automation is low;

[0004] In view of the above technical defects, a solution is proposed now. Summary of the Invention

[0005] The purpose of the present invention is to provide a management method based on intelligent gas equipment, which solves the problems that the prior art cannot reasonably judge the start-up risk of gas equipment before starting, and cannot conduct progressive and accurate assessment and timely warning of the gas transmission status and the environmental risks during the operation of gas equipment, and it is difficult to ensure the safe and stable operation of gas equipment and reduce the user management difficulty.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A management method based on intelligent gas equipment includes the following steps:

[0008] Step 1: Before the gas equipment operates, the gas equipment operation risk output module analyzes the start-up risk of the gas equipment, generates a start-up safety signal or a start-up danger signal through the analysis, and opens the gas valve and starts the gas equipment when the start-up safety signal is generated;

[0009] Step 2: After starting the gas equipment, the gas input monitoring unit monitors and analyzes the gas transmission status, and generates a gas transmission qualified signal or a gas transmission risk signal accordingly;

[0010] Step 3: When generating a qualified gas transmission signal, the combustion area monitoring unit monitors the area where the gas equipment is located, judges the environmental risk of the area where it is located, and generates a high-threat signal for the area or a low-threat signal for the area;

[0011] Step 4: When generating a start-up danger signal, a gas risk signal or a high-threat signal for the area, the display management terminal triggers an early warning mechanism, closes the gas valve, and sends an alarm message to the user intelligent terminal.

[0012] Furthermore, the specific analysis process of the gas equipment operation risk output module is as follows:

[0013] Collect the interval duration between the production date of the gas equipment and the current date and mark it as the first influence duration, and collect the total duration of the gas equipment in a high-temperature state and the total duration in a humid state during the historical stage and mark them as the second influence duration and the third influence duration respectively;

[0014] Assign corresponding preset weight coefficients to the first influence duration, the second influence duration and the third influence duration respectively, multiply the first influence duration, the second influence duration and the third influence duration by the corresponding preset weight coefficients respectively, and mark the sum value of the three groups of product results as the safety influence coefficient; Compare the safety influence coefficient with the preset upper threshold of the safety influence coefficient. If the safety influence coefficient exceeds the preset upper threshold of the safety influence coefficient, generate a start-up danger signal.

[0015] Furthermore, if the safety influence coefficient does not exceed the preset upper threshold of the safety influence coefficient, several groups of preset safety influence coefficient ranges are set in advance, and each group of preset safety influence coefficient ranges corresponds to a group of standard inspection interval durations; Compare the safety influence coefficient with all the preset safety influence coefficient ranges one by one, mark the preset safety influence coefficient range containing the corresponding safety influence coefficient as the selected range, and mark the standard inspection interval duration corresponding to the selected range as the matching duration;

[0016] Obtain the moment of the previous gas equipment inspection and mark it as the actual inspection interval duration, compare the actual inspection interval duration with the corresponding matching duration. If the actual inspection interval duration exceeds the corresponding matching duration, generate a start-up danger signal; If the actual inspection interval duration does not exceed the corresponding matching duration, generate a start-up safety signal.

[0017] Furthermore, the gas input monitoring unit is communicatively connected to the quality inspection unit and the input stability analysis unit. The quality inspection module inspects the quality status of the input gas, obtains the gas quality inspection value through the inspection, and sends the gas quality inspection value to the gas input monitoring unit; The input stability analysis unit analyzes the input stability of the input gas, obtains the input stability evaluation value through the analysis, and sends the input stability evaluation value to the gas input monitoring unit;

[0018] After the gas input monitoring unit receives the gas quality inspection value and the incoming stability evaluation value, it numerically compares the gas quality inspection value and the incoming stability evaluation value with the preset gas quality inspection threshold and the preset incoming stability evaluation threshold respectively. If the gas quality inspection value or the incoming stability evaluation value exceeds the corresponding preset threshold, a gas transmission risk signal is generated; if both the gas quality inspection value and the incoming stability evaluation value do not exceed the corresponding preset threshold, a gas transmission qualified signal is generated.

[0019] Furthermore, the analysis process of the quality inspection unit includes:

[0020] Obtain the concentration of non-combustible gas in the input gas and mark it as the non-combustible occupancy ratio, and collect the moisture content and particulate matter content in the input gas and mark them as the moisture inspection value and the particle inspection value respectively. Calculate the gas inspection value by numerically calculating the non-combustible occupancy ratio, the moisture inspection value, and the particle inspection value.

[0021] Numerically compare the gas inspection value with the preset gas inspection threshold. If the gas inspection value exceeds the preset gas inspection threshold, mark the corresponding gas inspection value as the gas abnormal inspection value; obtain the number of gas abnormal inspection values within a unit time and calculate the ratio with the number of gas inspection values to obtain the gas quality inspection value.

[0022] Furthermore, the specific analysis process of the incoming stability analysis unit is as follows:

[0023] Obtain the gas pressure and gas flow rate of the input gas. Calculate the variance of all gas pressures within a unit time to obtain the gas pressure wave value, and calculate the variance of all gas flow rates within a unit time to obtain the gas flow wave value.

[0024] And obtain the average value of the gas pressure of the input gas within a unit time and mark the deviation value compared with the currently set standard gas pressure value as the gas pressure deviation value, and obtain the average value of the gas flow rate of the input gas within a unit time and mark the deviation value compared with the currently set standard gas flow rate value as the gas flow deviation value; calculate the incoming stability evaluation value by numerically calculating the gas pressure wave value, the gas flow wave value, the gas pressure deviation value, and the gas flow deviation value.

[0025] Furthermore, the specific analysis process of the combustion area monitoring unit includes:

[0026] Obtain the concentration of combustible gas and the concentration of harmful gas in the area where the gas equipment is located and mark them as the area combustible coefficient and the area harmful coefficient respectively. Numerically compare the area combustible coefficient and the area harmful coefficient with the preset area combustible coefficient threshold and the preset area harmful coefficient threshold respectively. If the area combustible coefficient or the area harmful coefficient exceeds the corresponding preset threshold, it is determined that the current is in the area dangerous state.

[0027] Obtain the total duration in the area dangerous state within a unit time and mark it as the area danger value, calculate the average value of all area combustible coefficients within the unit time to obtain the combustible detection value, and calculate the average value of all area harmful coefficients within the unit time to obtain the harmful detection value;

[0028] Calculate the combustion area monitoring value by performing numerical calculations on the area danger value, combustible detection value, and harmful detection value, and perform a numerical comparison between the combustion area monitoring value and the preset combustion area monitoring threshold value. If the combustion area monitoring value exceeds the preset combustion area monitoring threshold value, generate an area high-threat signal; if the combustion area monitoring value does not exceed the preset combustion area monitoring threshold value, generate an area low-threat signal.

[0029] Further, the combustion area monitoring unit is communicatively connected to the ventilation supervision execution unit. The combustion area monitoring unit sends the area high-threat signal to the ventilation supervision execution unit. When the ventilation supervision execution unit receives the area high-threat signal, it turns on the ventilation equipment, and marks the excess value of the combustion area monitoring value compared to the preset combustion area monitoring threshold value as the area danger excess value. Set several groups of preset area danger excess value ranges in advance, and each group of preset area danger excess value ranges corresponds to a set of ventilation speed standard values respectively;

[0030] Perform a numerical comparison between the area danger excess value and all preset area danger excess value ranges, mark the preset area danger excess value range containing the corresponding area danger excess value as the optimal range, and mark the ventilation speed standard value corresponding to the optimal range as the optimal speed; after determining the optimal speed, the ventilation supervision execution unit makes the ventilation equipment operate at the optimal speed to discharge the internal gas to the outside.

[0031] Further, the display management terminal is communicatively connected to the management risk assessment module. The management risk assessment module is used to set the detection period, analyze and evaluate the operation management risk of the gas equipment during the detection period, and accordingly determine whether to generate a management alarm signal. When generating a management alarm signal, it sends it to the display management terminal and the user intelligent terminal.

[0032] Further, the specific analysis process of the management risk assessment module is as follows:

[0033] Obtain the number of times the gas transmission risk signal is generated and the number of times the area high-threat signal is generated during the detection period and mark them as the gas transmission risk value and the area threat value respectively, and collect the average value of the delay duration when the gas valve corresponding to the gas equipment is closed during the detection period and mark it as the gas valve closing delay value;

[0034] During the use of the gas equipment, the area where the gas equipment is located is monitored through a camera, and the personnel in the area are captured based on the monitoring images. If no personnel images are captured in the corresponding area, it is determined that the current state is an abnormal combustion supervision state; when the duration of the abnormal combustion supervision state exceeds the corresponding duration threshold, the combustion supervision alarm symbol XK-1 is assigned.

[0035] The number of times the combustion supervision alarm symbol XK-1 is assigned during the detection period is obtained and marked as the combustion supervision alarm value, and the ratio of the total duration of the abnormal combustion supervision state to the total operating duration of the gas equipment during the detection period is calculated to obtain the combustion supervision abnormal occupancy value.

[0036] By numerically calculating the gas transportation risk value, regional threat value, gas closure extension value, combustion supervision alarm value, and combustion supervision abnormal occupancy value, the gas equipment management evaluation coefficient is obtained. The gas equipment management evaluation coefficient is numerically compared with the preset gas equipment management evaluation coefficient threshold. If the gas equipment management evaluation coefficient exceeds the preset gas equipment management evaluation coefficient threshold, a management alarm signal is generated.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] 1. In the present invention, before the operation of the gas equipment, the start-up risk is analyzed through the gas equipment operation risk output module. When the start-up safety signal is generated, the gas valve is opened and the gas equipment is started. The gas input monitoring unit monitors and analyzes the gas transportation condition. When the gas transportation qualified signal is generated, the risk of the area where the gas equipment is located is monitored and analyzed. When the start-up danger signal, gas risk signal, or regional high-threat signal is generated, the gas valve is in the closed state and an alarm message is sent to the user intelligent terminal. The level of intelligence and automation is high, significantly improving the use safety of the gas equipment and reducing the user management difficulty.

[0039] 2. In the present invention, through the management risk assessment module, the operation management risk of the gas equipment during the detection period is analyzed and evaluated, and accordingly, it is judged whether to generate a management alarm signal. When the management alarm signal is generated, it is sent to the display management terminal and the user intelligent terminal to strengthen the operation management of the gas equipment in a timely manner, and further ensure the safe and stable operation of the gas equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] For the convenience of those skilled in the art to understand, the present invention will be further described below with reference to the accompanying drawings;

[0041] Figure 1 It is the method flow chart of the first embodiment in the present invention;

[0042] Figure 2 It is the system block diagram of the first embodiment in the present invention;

[0043] Figure 3 This is the system block diagram of the second embodiment in the present invention. Specific implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1: As Figure 1-2 shown, the management method based on intelligent gas equipment proposed by the present invention includes the following steps:

[0046] Step 1: Before the gas equipment operates, the gas equipment operation risk output module analyzes the startup risk of the gas equipment, generates a startup safety signal or a startup danger signal through the analysis. When the startup safety signal is generated, the gas valve is opened and the gas equipment is started, so as to ensure the safe startup of the gas equipment and reduce its operation hidden dangers. The specific analysis process is as follows:

[0047] The interval duration from the production date of the gas equipment to the current date is collected and marked as the first influence duration, and the total duration of the gas equipment in the high-temperature state and the total duration in the humid state in the historical stage are collected and marked as the second influence duration and the third influence duration respectively.

[0048] Corresponding preset weight coefficients are assigned to the first influence duration, the second influence duration, and the third influence duration respectively, and the values of the assigned preset weight coefficients are all positive numbers; the first influence duration, the second influence duration, and the third influence duration are respectively multiplied by the corresponding preset weight coefficients, and the sum value of the three product results is marked as the safety influence coefficient.

[0049] The safety influence coefficient is numerically compared with the preset upper threshold of the safety influence coefficient. If the safety influence coefficient exceeds the preset upper threshold of the safety influence coefficient, it indicates that the life condition of the gas equipment is poor and the current startup operation risk is large, then a startup danger signal is generated.

[0050] If the safety influence coefficient does not exceed the preset upper threshold of the safety influence coefficient, several groups of preset safety influence coefficient ranges are preset in advance, and each group of preset safety influence coefficient ranges corresponds to a group of standard inspection interval durations respectively; it should be noted that the larger the value of the preset safety influence coefficient range, the smaller the value of the corresponding standard inspection interval duration.

[0051] Compare the safety impact factor with all preset safety impact factor ranges one by one. Mark the preset safety impact factor range containing the corresponding safety impact factor as the selected range, and mark the standard inspection interval duration corresponding to the selected range as the matching duration;

[0052] Obtain the time of the previous adjacent inspection of the gas equipment and mark it as the actual inspection interval duration. Compare the actual inspection interval duration with the corresponding matching duration numerically. If the actual inspection interval duration exceeds the corresponding matching duration, it indicates that the gas equipment has not been inspected in time and the startup operation risk is relatively high, then generate a startup danger signal; if the actual inspection interval duration does not exceed the corresponding matching duration, it indicates that the startup operation risk of the gas equipment is relatively high at present, then generate a startup safety signal.

[0053] Step 2: After starting the gas equipment, the gas input monitoring unit monitors and analyzes the gas transmission condition, and accordingly generates a gas transmission qualified signal or a gas transmission risk signal, which can comprehensively evaluate the gas transmission risk based on the quality condition and transmission stability condition of the input gas, so as to conduct a cause investigation in time and make reasonable improvement measures, and further improve the operation safety of the gas equipment;

[0054] It should be noted that the gas input monitoring unit is communicatively connected to the quality inspection unit and the inlet stability analysis unit. The quality inspection module inspects the quality condition of the input gas, obtains the gas quality inspection value ZP through the inspection, and sends the gas quality inspection value ZP to the gas input monitoring unit, which can not only accurately feedback the quality condition of the input gas, but also provide data support for the analysis process of the gas input monitoring unit to ensure the comprehensiveness of its analysis and the accuracy of the analysis result. The analysis process of the quality inspection unit is as follows:

[0055] Obtain the concentration of non-combustible gas in the input gas and mark it as the non-combustible ratio. Collect the moisture content and particulate matter content in the input gas and mark them as the moisture inspection value and the particulate inspection value respectively. Numerically calculate the non-combustible ratio WX, the moisture inspection value QY, and the particulate inspection value SM through the formula YP = b×WX + e×QY + c×SM to obtain the gas inspection value YP; where b, e, and c are preset weight coefficients greater than zero, and the larger the value of the gas inspection value YP, the worse the real-time quality condition of the input gas;

[0056] Compare the gas inspection value YP with the preset gas inspection threshold numerically. If the gas inspection value YP exceeds the preset gas inspection threshold, it indicates that the real-time quality condition of the input gas is poor, then mark the corresponding gas inspection value as the gas abnormal inspection value;

[0057] Obtain the quantity of gas inspection values within a unit time and calculate the ratio with the quantity of gas inspection values to obtain the gas quality inspection value ZP; moreover, the larger the value of the gas quality inspection value ZP, the worse the comprehensive quality condition of the input gas within a unit time, and the more unfavorable it is to ensure the combustion effect and combustion safety;

[0058] The input stability analysis unit analyzes the input stability of the input gas. Through the analysis, the input stability evaluation value HX is obtained, and the input stability evaluation value HX is sent to the gas input monitoring unit. It can not only accurately feedback the input stability condition of the input gas, but also provide data support for the analysis process of the gas input monitoring unit to ensure the comprehensiveness of its analysis and the accuracy of the analysis result; the specific analysis process of the input stability analysis unit is as follows:

[0059] Obtain the gas pressure and gas flow rate of the input gas. Calculate the variance of all gas pressures within a unit time to obtain the gas pressure wave value, and calculate the variance of all gas flow rates within a unit time to obtain the gas flow wave value; it should be noted that the larger the values of the gas pressure wave value and the gas flow wave value, the more obvious the fluctuations of the pressure and flow rate in the gas transmission process;

[0060] And obtain the average value of the gas pressure of the input gas within a unit time and mark the deviation value compared with the currently set standard gas pressure value as the gas pressure deviation value, and obtain the average value of the gas flow rate of the input gas within a unit time and mark the deviation value compared with the currently set standard gas flow rate value as the gas flow deviation value;

[0061] Perform numerical calculation on the gas pressure wave value SW, the gas flow wave value GN, the gas pressure deviation value PY, and the gas flow deviation value WL through the formula HX = wq×SW + tu×GN + ny×PY + sp×WL to obtain the input stability evaluation value HX; where wq, tu, ny, and sp are preset weight coefficients with values greater than zero, and moreover, the larger the value of the input stability evaluation value HX, the more non-standard the gas transmission execution within a unit time and the greater the potential safety hazards;

[0062] After receiving the gas quality inspection value ZP and the input stability evaluation value HX, the gas input monitoring unit numerically compares the gas quality inspection value ZP and the input stability evaluation value HX with the preset gas quality inspection threshold and the preset input stability evaluation threshold respectively. If the gas quality inspection value ZP or the input stability evaluation value HX exceeds the corresponding preset threshold, a gas transmission risk signal is generated; if both the gas quality inspection value ZP and the input stability evaluation value HX do not exceed the corresponding preset threshold, a gas transmission qualified signal is generated.

[0063] Step 3: When generating a qualified gas transmission signal, the combustion area monitoring unit monitors the area where the gas equipment is located, judges the environmental risk of the area where it is located, and generates a high-threat signal for the area or a low-threat signal for the area, which can reasonably judge the probability of gas leakage and incomplete combustion in the area where the combustion equipment is located, so as to timely remind the user to take corresponding treatment measures, which is beneficial to avoiding casualties and property losses; the specific analysis process of the combustion area monitoring unit is as follows:

[0064] Obtain the concentration of combustible gases (including the sum value of the concentrations of combustible gases such as methane, carbon monoxide, and hydrogen) and the concentration of harmful gases (including the sum value of the concentrations of harmful gases such as hydrogen sulfide and sulfur dioxide) in the area where the gas equipment is located, and mark them as the regional combustible coefficient and the regional harmful coefficient respectively. Compare the regional combustible coefficient and the regional harmful coefficient with the preset regional combustible coefficient threshold and the preset regional harmful coefficient threshold respectively. If the regional combustible coefficient or the regional harmful coefficient exceeds the corresponding preset threshold, it is judged that the current is in a regional dangerous state;

[0065] Obtain the total duration in the regional dangerous state per unit time and mark it as the regional danger value, and calculate the average value of all regional combustible coefficients within the unit time to obtain the combustible detection value, and calculate the average value of all regional harmful coefficients within the unit time to obtain the harmful detection value;

[0066] Perform numerical calculation on the regional danger value YM, the combustible detection value FP, and the harmful detection value QW through the formula RY = uy×YM + mp×FP + bg×QW to obtain the combustion area monitoring value RY; where uy, mp, and bg are preset weight coefficients with values greater than zero, and moreover, the larger the numerical value of the combustion area monitoring value RY, the worse the regional environment performance of the area where the gas equipment is located, and the greater the probability of leakage and incomplete combustion;

[0067] Compare the combustion area monitoring value RY with the preset combustion area monitoring threshold. If the combustion area monitoring value RY exceeds the preset combustion area monitoring threshold, it indicates that the regional environment performance of the area where the gas equipment is located is poor, and the probability of leakage and incomplete combustion is large, then generate a high-threat signal for the area; if the combustion area monitoring value RY does not exceed the preset combustion area monitoring threshold, it indicates that the regional environment performance of the area where the gas equipment is located is good, and the probability of leakage and incomplete combustion is small, then generate a low-threat signal for the area.

[0068] Step 4: When generating a start-up danger signal, a gas risk signal, or a high-threat signal for the area, the display management terminal triggers an early warning mechanism, closes the gas valve, and sends an alarm message to the user's intelligent terminal, realizing timely alarm during the use of the gas equipment and automatically performing protection operations, with high intelligence and automation levels, significantly improving the use safety of the gas equipment and reducing the user management difficulty.

[0069] Furthermore, the combustion area monitoring unit is communicatively connected to the ventilation supervision execution unit. The combustion area monitoring unit sends the area high-threat signal to the ventilation supervision execution unit. When the ventilation supervision execution unit receives the area high-threat signal, it turns on the ventilation equipment to automatically discharge the internal gas, ensuring indoor safety. Moreover, the excess value of the combustion area monitoring value RY compared to the preset combustion area monitoring threshold value is marked as the area risk excess value;

[0070] Several groups of preset area risk excess value ranges are set in advance, and each group of preset area risk excess value ranges corresponds to a group of ventilation speed standard values respectively; it should be noted that the larger the value of the preset area risk excess value range, the larger the corresponding ventilation speed standard value;

[0071] The area risk excess value is numerically compared with all the preset area risk excess value ranges. The preset area risk excess value range containing the corresponding area risk excess value is marked as the optimal range, and the ventilation speed standard value corresponding to the optimal range is marked as the optimal speed; after determining the optimal speed, the ventilation supervision execution unit makes the ventilation equipment operate at the optimal speed to discharge the internal gas to the outside world, which can reasonably determine the exhaust speed, ensuring the internal gas discharge efficiency while reducing energy consumption.

[0072] Embodiment 2: As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that the display management terminal is communicatively connected to the management risk assessment module. The management risk assessment module is used to set the detection period. Preferably, the detection period is 25 days; the operation management risk of the gas equipment during the detection period is analyzed and evaluated, and based on this, it is judged whether a management alarm signal is generated. When a management alarm signal is generated, it is sent to the display management terminal and the user intelligent terminal. After receiving the management alarm signal, the user timely strengthens the operation management of the gas equipment to further ensure the safe and stable operation of the gas equipment; the specific analysis process of the management risk assessment module is as follows:

[0073] The number of times the gas transmission risk signal is generated and the number of times the area high-threat signal is generated during the detection period are obtained and marked as the gas transmission risk value and the area threat value respectively, and the average value of the delay duration when the gas valve corresponding to the gas equipment is closed during the detection period is collected and marked as the gas valve closing delay value;

[0074] Moreover, during the use of the gas equipment, the area where the gas equipment is located is monitored through a camera, and the personnel in the area are captured based on the monitoring image. If no personnel image is captured in the corresponding area, it is judged that the current is in an abnormal combustion supervision state; when the duration of the abnormal combustion supervision state exceeds the corresponding duration threshold, the combustion supervision alarm symbol XK-1 is assigned;

[0075] Obtain the number of times the combustion supervision alarm symbol XK-1 is given during the detection period and mark it as the combustion supervision alarm value, and calculate the ratio of the total duration in the abnormal combustion supervision state during the detection period to the total operating duration of the gas equipment during the detection period to obtain the combustion supervision abnormal occupancy value;

[0076] Perform numerical calculation on the gas transportation risk value XP, regional threat value SR, gas closure extension value HN, combustion supervision alarm value FU, and combustion supervision abnormal occupancy value DF through the formula TX = aw×XP + ru×SR + es×HN + tp×FU + mg×DF to obtain the gas equipment management evaluation coefficient TX; where, aw, ru, es, tp, mg are preset weight coefficients greater than zero, and the larger the value of the gas equipment management evaluation coefficient TX, the greater the overall management risk for the operation of the gas equipment during the detection period;

[0077] Perform a numerical comparison between the gas equipment management evaluation coefficient TX and the preset gas equipment management evaluation coefficient threshold. If the gas equipment management evaluation coefficient TX exceeds the preset gas equipment management evaluation coefficient threshold, it indicates that the overall management risk for the operation of the gas equipment during the detection period is relatively large, and it is necessary to strengthen the operation management of the gas equipment in a timely manner in the future, then generate a management alarm signal.

[0078] The working principle of the present invention: When in use, the gas equipment operation risk output module analyzes the start-up risk of the gas equipment before it starts. When a start-up safety signal is generated, the gas valve is opened and the gas equipment is started to ensure the safe start-up of the gas equipment and reduce its operation hazards. After the gas equipment is started, the gas input monitoring unit monitors and analyzes the gas transportation condition, and comprehensively evaluates the gas transportation risk based on the quality condition and transportation stability condition of the input gas. When a qualified gas transportation signal is generated, the combustion area monitoring unit monitors the area where the gas equipment is located, and reasonably judges the probability of gas leakage and incomplete combustion in the area where the combustion equipment is located. When a start-up danger signal, gas risk signal or regional high-threat signal is generated, the gas valve is in the closed state and an alarm message is sent to the user intelligent terminal to achieve timely alarm and automatic protection operation during the use of the gas equipment, with high intelligence and automation levels, significantly improving the use safety of the gas equipment and reducing the user management difficulty.
