The terms "include", "comprise", "have" and their variants all mean "including but not limited to", unless otherwise particularly emphasized in other ways.

[0073] The following will describe this application in detail in conjunction with specific embodiments.

[0074] In one embodiment, as Figure 1 shown, a flow schematic diagram of a method for real-time monitoring and early warning of combustible gas is specifically proposed. This method is mainly applied to a server, can also be implemented depending on a computer program, can be implemented depending on a single-chip microcomputer, and can also run on a combustible gas real-time monitoring and early warning system based on the von Neumann architecture. This computer program can be integrated into an application or run as an independent tool-type application.

[0075] Specifically, the method for real-time monitoring and early warning of combustible gas includes:

[0076] Step 101: Receive the combustible gas concentration sent by the detection sensors in multiple combustible gas monitoring units through the network, and obtain the signal connection status and signal strength of the network. The multiple combustible gas monitoring units are in one area.

[0077] In a specific implementation scenario, there are multiple combustible gas monitoring units in an area. The server is connected to each combustible gas monitoring unit through Narrow Band Internet of Things (NBIoT) and forms a real-time monitoring and early warning system for combustible gas. The status gateway software of the real-time monitoring and early warning system for combustible gas can be developed under an operating system, using an embedded application program and based on the standard peripheral library of the STM32 series of single-chip microcontrollers. The development software version can be freely selected. The status gateway software of the real-time monitoring and early warning system for combustible gas can be burned into the STM32 series of single-chip microcontrollers through a USB serial port for operation.

[0078] First, the monitoring gateway software needs to be compiled and downloaded. On the server side, the numbers of the detection sensors and relevant channel information in each combustible gas monitoring unit need to be added. Then, after the external wiring is completed, the combustible gas alarm controller to be monitored and the connected sensor devices are locally bound to the monitoring gateway software together.

[0079] The monitoring gateway software will check the network operator and signal connection status by itself. When the detection sensor cannot be connected to the NBIoT network, the indicator light of the hardware device will prompt the user that the current network cannot be connected in a constantly lit manner. After the monitoring gateway software determines the network situation, it will send an HTTP message request to the target server for connection. After establishing a reliable connection, it starts to upload the device ID number. After the device ID number is confirmed as a logged-in device ID number by the server, the monitoring gateway software starts to obtain the string sent by the combustible gas controller. The server obtains the gas concentration of each device according to the received string information. The gas concentration can be specifically understood as the gas concentration value. The monitoring gateway software will also monitor the signal strength of the current network in real time.

[0080] Step 102: Obtain the operating condition values of each detection sensor according to the combustible gas concentration.

[0081] In the embodiment of the present application, the operating condition value of the detection sensor can be understood as the degree of damage of the detection sensor. For example, in a kitchen, oil fume or sewage may adhere to the detection sensor, resulting in the failure of the detection sensor.

[0082] Specifically, according to the combustible gas concentration received by the server, it can be determined whether there is a large deviation in the detected combustible gas concentration, so as to determine whether there is a problem with the detection sensor, and the operating condition value of the detection sensor is analyzed according to the deviation of the change amplitude of the combustible gas concentration.

[0083] Optionally, the detection sensor is connected to the STM32 single-chip microcontroller, and the STM32 single-chip microcontroller will also send the detection sensor fault information to the server in the form of a string, and the server analyzes the operating condition value of the detection sensor according to the received string information.

[0084] Step 103: According to the first weight formula, and in combination with the combustible gas concentration, signal connection status, signal strength, and operating condition value of the detection sensor of each combustible gas monitoring unit, obtain the unit risk warning value corresponding to each combustible gas monitoring unit.

[0085] The first weight formula refers to the formula used to calculate the unit risk warning value of each combustible gas monitoring unit. The unit risk warning value can be understood in the embodiments of the present application as a value reflecting the risk degree of the combustible gas monitoring unit.

[0086] Specifically, according to the importance values of multiple factors such as the combustible gas concentration, signal connection status, signal strength, and operating condition value of each combustible gas monitoring unit, in combination with the first weight formula, first calculate the risk weights corresponding to the multiple factors, and then obtain the unit risk warning value of each combustible gas monitoring unit through the risk weights.

[0087] Step 104: According to the second weight formula, and in combination with the unit risk warning value corresponding to each combustible gas monitoring unit, obtain the regional risk warning value.

[0088] The second weight formula refers to the formula used to calculate the regional risk warning value of the combustible gas monitoring area. The regional risk warning value can be understood in the embodiments of the present application as a value reflecting the risk degree of the combustible gas monitoring area.

[0089] Specifically, divide the multiple combustible gas monitoring units in the combustible gas monitoring area into two groups, one group is the combustible gas monitoring units that are related to each other, and the other group is the combustible gas monitoring units with no degree of association. Different risk weight coefficients are assigned to the two groups of different combustible gas monitoring units respectively. In combination with the risk weight coefficients and the unit risk warning value of each combustible gas monitoring unit, obtain the regional risk warning value through the second weight formula.

[0090] Step 105: Determine whether the regional risk warning value is greater than the first threshold. If the regional risk warning value is greater than the first threshold, a danger warning prompt is generated for the area.

[0091] Specifically, the server determines whether the calculated regional risk warning value is greater than the first threshold. If the regional risk warning is greater than the first warning, it means that there is a risk of combustible gas leakage in the combustible gas monitoring area, or the detection equipment is aging or unqualified, and there may be potential safety hazards in the combustible gas use area. The server generates a danger warning prompt and sends it to the relevant responsible personnel in the area.

[0092] Please refer to Figure 2 , Figure 2 ' is a schematic flowchart of another embodiment of a method for real-time monitoring and early warning of combustible gas provided by the present application.

[0093] Step 201: Receive the combustible gas concentration sent by the detection sensors in multiple combustible gas monitoring units through the network, and obtain the signal connection status and signal strength of the network. The multiple combustible gas monitoring units are in one area.

[0094] Specifically, for the relevant description of receiving the combustible gas concentration sent by the detection sensors in multiple combustible gas monitoring units through the network, and obtaining the signal connection status and signal strength of the network, with the multiple combustible gas monitoring units in one area, reference can be made to the detailed explanation in Step 101, and no further elaboration will be made here.

[0095] Step 202: Periodically analyze the multiple combustible gas concentrations to obtain the change range of the combustible gas concentration, and obtain the operating condition value of the detection sensor according to the change range of the combustible gas concentration.

[0096] Specifically, the server periodically analyzes the received combustible gas concentrations, and can establish a two-dimensional rectangular coordinate system with the combustible gas concentration and time. Under normal circumstances, the combustible gas concentration should be stable within one hour. If there is intermittent interruption of data, or if the combustible gas concentration shows an inclined change within a unit of time, it indicates that there is a problem with the detection sensor. The operating condition value of the detection sensor can be determined according to the intermittent interruption frequency of the data or the change range of the combustible gas concentration. For example, within a unit of time, if the combustible gas concentration is not received 3 times, the operating condition value of the detection sensor is set to 1. If the combustible gas concentration changes from 0.1 to 20 and then back to 0.1 within a unit of time, the operating condition value of the detection sensor is set to 5. That is, the larger the operating condition value of the detection sensor, the more serious the problem with the detection sensor.

[0097] Step 203: Set the importance values corresponding to the combustible gas concentration, signal state, signal strength, and operating state of the detection sensor. According to the importance scale table and the importance values, establish a unit risk matrix. According to the first preset formula, combined with the unit risk matrix, obtain the risk weights corresponding to the combustible gas concentration, signal connection status, signal strength, and operating condition value of the combustible gas monitoring unit. According to the second preset formula, combined with the risk weights corresponding to the combustible gas concentration, signal connection status, signal strength, and operating condition value of the combustible gas monitoring unit, calculate the unit risk warning value.

[0098] The importance value in the embodiments of the present application can be understood as the importance of multiple factors such as gas concentration, signal state, signal strength, and the operating state of the detection sensor for the risk assessment of the combustible gas monitoring unit. The importance scale table in the embodiments of the present application can be understood as a pairwise comparison between multiple factors such as combustible gas concentration, signal state, signal strength, and the operating state of the detection sensor to reflect which factor has a greater impact and to what extent specifically through the scale.

[0099] Specifically, if two factors are compared and have the same importance, the scale is set to 1; if one factor is slightly more important than the other, the scale is set to 3; if one factor is more important than the other, the scale is set to 5; if one factor is much more important than the other, the scale is set to 7; if one factor is extremely more important than the other, the scale is set to 9. For example, when comparing the gas concentration factor with the signal state factor, the gas concentration factor is more important than the signal state factor, and the scale is set to 5; when comparing the signal state factor with the signal strength factor, the signal state factor is slightly more important than the signal strength factor, and the scale is set to 3.

[0100] The unit risk matrix includes:

[0101]

[0102] In the formula, B is the unit risk matrix; b ij represents the comparison between B i and B j The value obtained by comparing with the importance scale table and the importance value.

[0103] The first preset formula includes:

[0104]

[0105]

[0106]

[0107] In the formula, i is the row coordinate of the unit risk matrix; j is the column coordinate of the unit risk matrix, and i, j = 1, 2,..., n; is the result obtained by normalizing each column of the unit risk matrix; is the sum of the row vectors of A = (a ij ) n×n ; W i is the weight vector obtained by normalizing .

[0108] The second preset formula includes:

[0109] X = W1X1 + W2X2 +... + W n X n ;

[0110] In the formula, X is the unit risk warning value; X n is the score of each index; W n is the weight of each index; n is the index serial number.

[0111] Specifically, set the importance values of multiple factors such as combustible gas concentration, signal status, signal strength, and the operating status of the detection sensor. For example, the importance value of combustible gas concentration can be set to 5, the importance value of signal status to 3, the importance value of signal strength to 2, and the importance value of the detection sensor to 1. Combine the importance values of each factor with the importance table, compare each factor pairwise, refer to the importance scale table to obtain the scale value, form a unit risk matrix from the scale values, and then according to the first preset formula, normalize each column of the unit risk matrix and sum by row to obtain a row vector. Normalize the row vector to obtain the risk weights of each factor. Through the second preset formula, multiply the combustible gas concentration, signal connection status, signal strength, and the operating status value of the detection sensor by the risk weights of each factor respectively to obtain the unit risk warning value.

[0112] Step 204: According to the second weight formula and in combination with the unit risk warning values corresponding to each gas monitoring unit, obtain the regional risk warning value.

[0113] The second weight formula includes:

[0114]

[0115] In the formula, X i are interconnected combustible gas monitoring units. The interconnected combustible gas monitoring units can be understood in the embodiments of the present application as that there is mutual influence between combustible gas monitoring units. When a safety problem occurs in one combustible gas monitoring unit, a chain reaction may occur, resulting in safety problems in other combustible gas monitoring units. For example, multiple combustible gas monitoring units are connected by a gas pipeline, or two combustible gas units are very close.

[0116] X j are non-interconnected combustible gas monitoring units. The non-interconnected combustible gas monitoring units can be understood in the embodiments of the present application as that there is no mutual influence between combustible gas units. For example, the distance between two combustible gas monitoring units is far, and they are not connected by the same gas pipeline. When a safety problem occurs in one combustible gas monitoring unit, it does not affect the other combustible gas monitoring unit.

[0117] Z1 is the weight corresponding to the interconnected gas monitoring units;

[0118] Z2 is the weight corresponding to the non-interconnected gas monitoring units.

[0119] Specifically, set the unit risk weights of interrelated combustible gas monitoring units to the same value. For non - interrelated combustible gas monitoring units, set different unit risk weights according to their importance levels. The sum of all unit risk weights is 1, and then obtain the regional risk warning value according to the second weight formula.

[0120] For example, a building is a combustible gas monitoring area. There are 4 residential houses in a building. Among them, two residential houses use the same combustible gas pipeline. That is, these two residential houses are interrelated combustible gas monitoring units, and the unit risk weight is set to 0.7. Among the other two residential houses, one house has 3 residents, and the unit risk weight is set to 0.2, and one house has no residents and is set to 0.1.

[0121] Step 205: Compare the combustible gas concentration with the second threshold and the third threshold. If the combustible gas concentration is greater than or equal to the second threshold, send the location of the gas detection unit to the fire department. If the combustible gas concentration is less than the second threshold and greater than or equal to the third threshold, send the location of the gas detection unit to the maintenance personnel.

[0122] Specifically, when comparing the combustible gas concentration with the second threshold and the third threshold, if the combustible gas concentration is greater than or equal to the second threshold, it indicates that there is a combustible gas leakage phenomenon in the combustible gas monitoring unit, and a great safety problem may occur at any time. The server sends the location of the combustible gas monitoring unit to the fire department to request professionals to solve the problem. If the combustible gas concentration is less than the second threshold and greater than or equal to the third threshold, it indicates that there is a leakage phenomenon in the combustible gas monitoring unit, but it is not serious enough to cause a major safety problem. The server sends the location of the gas detection unit to the maintenance personnel to request the maintenance personnel to come to repair.

[0123] Step 206: Generate a regional rectification plan according to the danger warning prompt information and send the regional rectification plan to the regulatory department.

[0124] Specifically, there are many reasons for the regional risk warning value to exceed the safety threshold. It may be that the detection sensors in the entire region are faulty; it may be that there is a combustible gas leakage phenomenon in the interrelated combustible gas monitoring units, etc. All these may lead to safety problems in the entire region. The server finds out the relevant problems according to the danger warning prompt information, generates a regional rectification plan for the relevant problems, and sends it to the regulatory department so that the regulatory department can send professional supervisors to rectify the region.
