Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of oil and gas pipeline construction, and in particular to a method and device for establishing a monitoring network. Background Art

[0002] Oil and natural gas pipelines are characterized by large diameter, high pressure, and large transportation volume. According to the transportation route planning, they are often placed in locations that are difficult to observe, such as the surface or underground. Once pipeline aging, pipeline corrosion, or artificial drilling and oil theft occur, oil and natural gas leakage will occur, causing a series of serious consequences such as environmental pollution, production and transportation suspension, etc.

[0003] In related technologies, a sensor is installed at regular intervals on an oil or natural gas pipeline. The sensor is used to obtain data from the corresponding pipeline. Technicians go to the site to inspect the sensor at regular intervals to obtain data from the pipeline, and determine whether there is a fault in the pipeline based on the data.

[0004] However, the above methods require manual on-site inspection, which is not only costly and wastes manpower and financial resources, but also has a low degree of automation, low sensitivity, and low detection accuracy. Therefore, there is an urgent need for a monitoring network establishment method to establish a network for monitoring oil and gas pipelines, thereby improving the degree of automation and accuracy of oil and gas pipeline monitoring.

[0074] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0075] The embodiment of the present application provides a method for establishing a monitoring network, which can be described by the interaction between an electronic device and a sensor node, or by the interaction between a server and a sensor node. The electronic device is any electronic product that can interact with a user through one or more methods such as a keyboard, a touchpad, a touch screen, a remote control, voice interaction, or a handwriting device. For example, a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a handheld computer PPC (Pocket PC), and a tablet computer. The server is a single server, or a server cluster consisting of multiple servers, or at least one of a cloud computing platform and a virtualization center, and the embodiment of the present application does not limit this.

[0076] Those skilled in the art should understand that the above-mentioned electronic devices and servers are only examples. Other existing or future electronic devices or servers that are applicable to this application should also be included in the scope of protection of this application and are incorporated herein by reference.

[0077] This embodiment provides a method for establishing a monitoring network. The method for establishing a monitoring network can be described by the interaction between electronic devices and sensor nodes. Figure 1 The method includes the following steps 101 to 108.

[0078] In step 101, the electronic device determines, based on hardware information of N sensor nodes, a first sensor node whose hardware information meets target requirements.

[0079] In one possible implementation, N is an integer greater than 1, and all N sensor nodes have a communication connection with the oil and gas pipeline. In order to facilitate the acquisition of relevant data of the oil and gas transmission pipeline, one or more sensor nodes are installed at intervals on the oil and gas transmission pipeline, or sensor nodes are installed in the valve room of the oil and gas station with electronic equipment, or sensor nodes are installed in edge devices such as the oil and gas station monitoring station, so that the installed sensor nodes can obtain relevant data of the oil and gas transmission pipeline, thereby facilitating the electronic equipment to obtain relevant data of the oil and gas transmission pipeline, and then the electronic equipment can determine whether there is a fault in the oil and gas transmission pipeline based on the relevant data of the oil and gas transmission pipeline.

[0080] The sensor node is any one of a pressure sensor, a temperature sensor, and a weight sensor, or may be other types of sensor nodes. The embodiment of the present application does not limit the type of the sensor node.

[0081] In a possible implementation, a technician inputs the hardware information of each sensor node into the electronic device, so that the electronic device determines a first sensor node whose hardware information meets target requirements based on the hardware information of the sensor nodes.

[0082] In one possible implementation, the hardware information of the sensor node includes at least one of power, energy, and storage rate of the sensor node. Based on the hardware information of the sensor node, determining the first sensor node whose hardware information meets the target requirement may be performed in the following situations.

[0083] Case 1: In response to the hardware information of the sensor node including the power of the sensor node, a sensor node whose power meets the power requirement among the N sensor nodes is determined as the first sensor node.

[0084] For example, the sensor node with the highest power among the N sensor nodes is determined as the first sensor node. Alternatively, the N sensor nodes are sorted in ascending or descending order of power, and any sensor node among the sensor nodes ranked at a target number of bits is determined as the first sensor node. The target number of bits is any value, such as 3 or 5.

[0085] Case 2: In response to the hardware information of the sensor node including the energy of the sensor node, a sensor node whose energy meets the energy requirement among the N sensor nodes is determined as the first sensor node.

[0086] For example, the sensor node with the highest energy among the N sensor nodes is determined as the first sensor node. Alternatively, the N sensor nodes are sorted in ascending or descending energy order, and any sensor node among the sensor nodes ranked at a target number of bits is determined as the first sensor node. The target number of bits is any value, such as 3 or 5.

[0087] Case 3: In response to the hardware information of the sensor node including the storage rate of the sensor node, a sensor node whose storage rate meets the storage rate requirement among the N sensor nodes is determined as the first sensor node.

[0088] For example, the sensor node with the highest storage rate among the N sensor nodes is determined as the first sensor node. Alternatively, the N sensor nodes are sorted in ascending or descending order of storage rate, and any sensor node among the sensor nodes ranked at a target number of bits is determined as the first sensor node. The target number of bits is any value, such as 3 or 5.

[0089] Case 4: In response to the sensor node hardware information including at least two of the power, energy and storage rate of the sensor node, a sensor node among the N sensor nodes that meets at least two of the corresponding requirements of power, energy and storage rate is determined as the first sensor node.

[0090] Exemplarily, the hardware information of the sensor node includes the power and energy of the sensor node, and the sensor node with the largest power and the largest energy among the N sensor nodes is determined as the first sensor node.

[0091] It should be noted that the hardware information of the sensor node may also include the signal and quality of the sensor node. When determining the first sensor node based on the hardware information of the sensor node, the sensor node with the strongest signal may be determined as the first sensor node, or the sensor node with the best quality may be determined as the first sensor node. Of course, the hardware information of the sensor node may also include other information, which is not limited in the embodiments of the present application.

[0092] It should also be noted that other methods may be used to determine the first sensor node from the N sensor nodes. For example, a sensor node may be randomly determined from the N sensor nodes as the first sensor node. The embodiment of the present application does not limit the process of determining the first sensor node.

[0093] In step 102, the electronic device sends an information acquisition instruction to the first sensor node, where the information acquisition instruction is used to determine, through the first sensor node, a second sensor node whose received signal strength meets a target strength.

[0094] In one possible implementation, after the electronic device determines the first sensor node whose hardware information meets the target requirements in the above step 101, it directly sends an information acquisition instruction to the first sensor node, thereby determining a second sensor node whose received signal strength meets the target strength through the first sensor node, and the number of the second sensor node is at least one.

[0095] In step 103, the first sensor node receives an information acquisition instruction sent by the electronic device.

[0096] In a possible implementation, after the first sensor node receives the signal acquisition instruction sent by the electronic device, it executes steps 104 to 106 to determine the second sensor node.

[0097] In step 104 , the first sensor node sends node information of the first sensor node to N−1 sensor nodes excluding the first sensor node among the N sensor nodes according to the first power level.

[0098] Among them, based on different sensor nodes, their power levels also vary. Generally, the power levels of sensor nodes are 0-10 levels, or 0-13 levels, where level 0 is the maximum power level and level 10 or level 13 is the minimum power level.

[0099] In one possible implementation, the first power level is the minimum power level, that is, the first power level is level 10 or level 13. The first sensor node transmits node information of the first sensor node to N-1 sensor nodes other than the first sensor node among the N sensor nodes according to the first power level. The node information is in the form of a data message, and the data message includes a data header, data content, and a data trailer. The data header includes location information of the first sensor node, the data content includes IP (Internet Protocol) information of the first sensor node and the operating status of the first sensor node, and the data trailer includes vendor information of the first sensor node. Of course, other content may also be transmitted to the N-1 sensor nodes other than the first sensor node among the N sensor nodes, and this is not limited in this embodiment of the present application.

[0100] In one possible implementation, node information of a first sensor node is transmitted to N-1 sensor nodes other than the first sensor node among N sensor nodes at a first power level in order to receive unicast messages returned by the N-1 sensor nodes. If unicast messages returned by the N-1 sensor nodes are not received within a target time, the power level for transmitting the node information of the first sensor node is increased, and the node information of the first sensor node is continuously transmitted to the N-1 sensor nodes at the increased power level until unicast messages returned by M of the N-1 sensor nodes are received. If unicast messages returned by any of the N-1 sensor nodes are still not received after the power level is increased to the maximum, a notification message is transmitted to the electronic device to notify the electronic device of establishing a monitoring network based on the first sensor node. M is an integer greater than or equal to 1 and less than N.

[0101] It should be noted that the target time can be any length of time, for example, the target time is 3 minutes, and another example is the target time is 1 minute. The embodiment of the present application does not limit the length of the target time.

[0102] For example, a first sensor node sends its node information to N-1 sensor nodes excluding the first sensor node among N sensor nodes at a power level of 10. If no sensor node replies to the unicast message within the target time (3 minutes), the power level is adjusted to 9, and the node information of the first sensor node is sent to N-1 sensor nodes at a power level of 9.

[0103] In step 105 , the first sensor node receives unicast messages returned by M sensor nodes among the N−1 sensor nodes. The unicast messages carry node information of the corresponding sensor nodes.

[0104] Among them, the unicast messages returned by the M sensor nodes are also in the form of data packets, including a data packet header, data content and a data packet trailer. Among them, the data packet header is the location information of the sensor node, the data content includes the IP information of the sensor node and the operating status of the sensor node, and the data packet trailer includes the supplier information of the sensor node.

[0105] For example, there are 10 sensor nodes installed on the oil and gas pipeline, namely sensor nodes 1 to 10. Sensor node 1 is the first sensor node. Sensor node 1 sends its node information to the remaining 9 sensor nodes at the first power level. Sensor nodes 2, 3, and 4 return unicast messages. The unicast message returned by sensor node 2 carries its node information, the unicast message returned by sensor node 3 carries its node information, and the unicast message returned by sensor node 4 carries its node information.

[0106] In step 106 , the first sensor node determines the received signal strengths of the M sensor nodes based on the node information of the M sensor nodes, and determines a sensor node whose received signal strength meets the target strength as the second sensor node.

[0107] In one possible implementation, since the node information of the M sensor nodes includes the IP information of the M sensor nodes, the signals and power levels of the M sensor nodes are determined based on the IP information of the M sensor nodes. Determining the received signal strengths of the M sensor nodes based on the node information of the M sensor nodes includes: determining the signals and power levels of the M sensor nodes based on the node information of the M sensor nodes; and determining the received signal strengths of the M sensor nodes based on the signals and power levels of the M sensor nodes.

[0108] Among them, different weight parameters can be assigned to the signal of the sensor node and the power of the sensor node, and the received signal strength of the sensor node is determined according to the signal of the sensor node, the weight parameter corresponding to the signal of the sensor node, and the power of the sensor node, the weight parameter corresponding to the power of the sensor node.

[0109] For example, the signal strength of sensor node 2 is 90, the battery level is 70, the weight parameter corresponding to the signal of the sensor node is 50%, and the weight parameter corresponding to the battery level of the sensor node is 50%. Based on the signal strength of sensor node 2, the battery level, the weight parameter corresponding to the signal of the sensor node, and the weight parameter corresponding to the battery level, it is determined that the received signal strength of sensor node 2 is 80.

[0110] It should be noted that the process of determining the received signal strength of other sensor nodes is consistent with the process of determining the received signal strength of the sensor node 2 described above, and will not be repeated here.

[0111] It should also be noted that the representation of the received signal strength of the sensor node can be in the form of a numerical value or a grid number. The above only takes the representation of the received signal strength of the sensor node as a numerical value as an example, and is not used to display the representation of the received signal strength.

[0112] In one possible implementation, after determining the received signal strengths of the M sensor nodes, the process of determining the sensor node whose received signal strength meets the target strength among the M sensor nodes as the second sensor node is as follows: determining the sensor node with the largest received signal strength among the M sensor nodes as the second sensor node.

[0113] It should be noted that other methods may also be used to determine the second sensor node, which is not limited in the embodiment of the present application.

[0114] In a possible implementation, the first sensor node may further send indication information to the second sensor node. The indication information is used to instruct the creation of a forward connection between the first sensor node and the second sensor node. The indication information is also used by the second sensor node to determine other second sensor nodes according to the process of the first sensor node determining the second sensor node.

[0115] In a possible implementation, the indication information further carries hop information for indicating a link speed between the first sensor node and the second sensor node.

[0116] The relationship between hop information and link speed is shown in Table 1 below.

[0117] Table 1

[0118] Link speed Hop Information >200MB 10 >20MB, ≤200MB 20 >4MB, ≤20MB 30 >500KB, ≤4MB 40 ≤500KB 50

[0119] It can be seen from Table 1 above that when the link speed is greater than or equal to 200MB (megabytes), the corresponding hop information is 10; when the link speed is greater than 20MB and less than or equal to 200MB, the corresponding hop information is 20; when the link speed is greater than 4MB and less than or equal to 20MB, the corresponding hop information is 30; when the link speed is greater than 500KB (kilobytes) and less than or equal to 4MB, the corresponding hop information is 40; when the link speed is less than or equal to 500KB, the corresponding hop information is 50.

[0120] It should be noted that the hop information carried in the indication information and used to indicate the link speed between the first sensor node and the second sensor node is hop information randomly determined by the first sensor node.

[0121] In one possible implementation, the first sensor node further needs to send network status information to M-1 sensor nodes other than the second sensor node among the M sensor nodes. The network status information is used to indicate the network status of the M-1 sensor nodes. Since the second sensor node has been determined among the M sensor nodes, the network status of the M-1 sensor nodes other than the second sensor node among the M sensor nodes is a dormant state. The network status information is sent to the M-1 sensor nodes to inform the M-1 sensor nodes that their network status is a dormant state.

[0122] It should be noted that the process of determining other second sensor nodes is consistent with the process of determining the second sensor node by the first sensor node, and will not be described in detail here.

[0123] For example, there are 10 sensor nodes installed on an oil and gas pipeline, namely sensor nodes 1 to 10. Sensor node 1 is the first sensor node. Sensor node 1 sends its node information to the remaining 9 sensor nodes at a first power level. Based on the unicast messages returned by the remaining 9 sensor nodes, sensor node 2 is determined to be the first second sensor node. Sensor node 2 sends its node information to the remaining 8 sensor nodes at a first power level. Based on the unicast messages returned by the remaining 8 sensor nodes, sensor node 3 is determined to be the second second sensor node. Sensor node 3 sends its node information to the remaining 7 sensor nodes, but does not receive any unicast messages from them. Even after adjusting the power level, no unicast messages are received. Therefore, sensor node 3 is determined to be the last second sensor node.

[0124] In step 107 , the first sensor node sends node information of the second sensor node to the electronic device.

[0125] In a possible implementation, after determining the second sensor node in step 106 , the first sensor node sends node information of the second sensor node to the electronic device, so that the electronic device establishes a target monitoring network based on the second sensor node.

[0126] In one possible implementation, after the second sensor node identifies a second second sensor node, it also needs to send the node information of the second second sensor node to the electronic device. After the second second sensor node identifies a third second sensor node, it also needs to send the node information of the third second sensor node to the electronic device. In other words, as soon as the first sensor node identifies the second sensor node, it needs to send the node information of the second sensor node to the electronic device, thereby making the target monitoring network established by the electronic device cover more comprehensive sensor nodes.

[0127] In step 108 , the electronic device establishes a target monitoring network based on the first sensor node and the second sensor node, where the target monitoring network is used to monitor the oil and gas pipeline.

[0128] In a possible implementation, the first sensor node and the second sensor node determined above are connected to obtain a target monitoring network, which is used to monitor whether there is a fault in the oil and gas pipeline.

[0129] In one possible implementation, after the target monitoring network is established based on the first sensor node and the second sensor node, the first monitoring network is re-established in response to receiving a network error message sent by any one of the first sensor node and the second sensor node. The process of re-establishing the first monitoring network is consistent with the process of establishing the target monitoring network, and will not be repeated here.

[0130] In one possible implementation, after establishing the target monitoring network, it is necessary to monitor the target monitoring network to prevent failures in the target monitoring network. The process of monitoring the target monitoring network is as follows: beacon information is sent to the first sensor node, which transmits the beacon information in the target monitoring network. The beacon information transmission process is used to detect whether there is a failure in the target monitoring network; in response to a pause in the beacon information transmission process that exceeds a target pause time, it is determined that there is a failure in the target monitoring network. The beacon information is information that carries inspection content or repair content, which is not limited in the embodiments of the present application.

[0131] In one possible implementation, in response to a target monitoring network failure, the target monitoring network needs to be processed to obtain a repaired target monitoring network. The process is as follows: based on the transmission process of beacon information, the faulty sensor node is determined; the faulty sensor node is processed to obtain a repaired target monitoring network.

[0132] In a possible implementation, there are two implementations described below to process the faulty sensor nodes and obtain a repaired target monitoring network.

[0133] Implementation method 1: Remove the faulty sensor nodes to obtain the repaired target monitoring network.

[0134] For example, the target monitoring network includes four sensor nodes: a first sensor node, a first second sensor node, a second second sensor node, and a third second sensor node. The pause time between the first second sensor node transmitting beacon information to the second second sensor node is greater than the target pause time. Therefore, the second second sensor node is determined to be a faulty sensor node and is removed. The remaining monitoring network, consisting of the first sensor node, the first second sensor node, and the third second sensor node, serves as the repaired target monitoring network.

[0135] Implementation method 2: determine the target sensor node, replace the faulty sensor node with the target sensor node, and obtain a repaired target monitoring network.

[0136] In one possible implementation, based on the node information of the faulty sensor node, the sensor nodes adjacent to the faulty sensor node are determined, a target sensor node is determined among the sensor nodes adjacent to the faulty sensor node, and the target sensor node is used to replace the faulty sensor node to obtain a repaired target monitoring network.

[0137] The process of determining a target sensor node from among the sensor nodes adjacent to the faulty sensor node is as follows: determining the received signal strengths of the sensor nodes adjacent to the faulty sensor node, and determining the sensor node with the highest received signal strength as the target sensor node. Alternatively, other methods can be used to determine the target sensor node from among the sensor nodes adjacent to the faulty sensor node, which is not limited in this embodiment of the present application.

[0138] It should be noted that, when there is only one sensor node adjacent to the faulty sensor node, the sensor node adjacent to the faulty sensor node is directly determined as the target sensor node.

[0139] For example, the target monitoring network includes four sensor nodes: a first sensor node, a first second sensor node, a second second sensor node, and a third second sensor node. The pause time between the first second sensor node transmitting beacon information to the second second sensor node is greater than the target pause time. Therefore, the second second sensor node is determined to be a faulty sensor node. Based on the node information of the second second sensor node, the adjacent sensor nodes are determined to be sensor nodes 5 and 6. The received signal strength of sensor node 5 is determined to be 80, and the received signal strength of sensor node 6 is determined to be 70. Since the received signal strength of sensor node 5 is higher than that of sensor node 6, sensor node 5 is determined to be the target sensor node. Sensor node 5 replaces the second second sensor node, resulting in a repaired target monitoring network. The repaired target monitoring network includes the first sensor node, the first second sensor node, sensor node 5, and the third second sensor node.

[0140] It should be noted that, in response to a target monitoring network failure, any of the above implementation methods can be selected to process the faulty sensor node to obtain a repaired target monitoring network, which is not limited in the embodiments of the present application.

[0141] It should be noted that the method for establishing the monitoring network can also be described by the interaction between the server and the sensor node. The embodiment of the present application only uses the method for establishing the monitoring network as an example of the interaction between the electronic device and the sensor node, and is not used to limit the present application.

[0142] In summary, the method of the present embodiment uses high-performance sensor nodes to establish a target monitoring network, resulting in low energy consumption. Using this target monitoring network for oil and gas pipeline monitoring can improve the accuracy of oil and gas pipeline monitoring, thereby reducing the communication error rate of the target monitoring network. Furthermore, since manual on-site testing is not required, the automation level of oil and gas pipeline monitoring can be increased.

[0143] Figure 2 The flowchart shown is a method for establishing a monitoring network provided in an embodiment of the present application. The electronic device is used as the execution body, and the method includes the following steps 201 to 203.

[0144] In step 201 , based on hardware information of N sensor nodes, a first sensor node whose hardware information meets target requirements is determined, where N is an integer greater than or equal to 1, and all the N sensor nodes have a communication connection with the oil and gas pipeline.

[0145] In a possible implementation, the process of determining the first sensor node is consistent with the process of step 101 above, which will not be described in detail here.

[0146] In step 202, an information acquisition instruction is sent to the first sensor node. The information acquisition instruction is used to determine, through the first sensor node, a second sensor node whose received signal strength meets the target strength. The number of the second sensor node is at least one.

[0147] In a possible implementation, the process of sending the information acquisition instruction to the first sensor node is consistent with the process of step 102 above, and will not be described in detail here.

[0148] In step 203, a target monitoring network is established based on the first sensor node and the second sensor node, and the target monitoring network is used to monitor the oil and gas pipeline.

[0149] In a possible implementation, the process of establishing the target monitoring network is consistent with the process of step 108 above, which will not be described in detail here.

[0150] This method uses high-performance sensor nodes to establish a target monitoring network, resulting in low energy consumption. This target monitoring network improves the accuracy of oil and gas pipeline monitoring, thereby reducing the communication error rate within the target monitoring network. Furthermore, since manual on-site inspections are no longer required, the automation level of oil and gas pipeline monitoring can be increased.

[0151] Figure 3 The flowchart shown is a method for establishing a monitoring network provided by an embodiment of the present application. The method is performed by a first sensor node and includes the following steps 301 to 305 .

[0152] In step 301, an information acquisition instruction sent by an electronic device is received, where the information acquisition instruction is used to determine a second sensor node whose received signal strength meets a target strength.

[0153] In a possible implementation, the process of receiving the information acquisition instruction sent by the electronic device is consistent with the process of the above step 103 and is not repeated here.

[0154] In step 302 , node information of the first sensor node is sent to N−1 sensor nodes excluding the first sensor node among the N sensor nodes according to a first power level, where N is an integer greater than 1.

[0155] In a possible implementation, the process of sending the node information of the first sensor node to N-1 sensor nodes other than the first sensor node among the N sensor nodes according to the first power level is consistent with the process of step 104 above, which is not repeated here.

[0156] In step 303 , unicast messages returned by M sensor nodes among the N−1 sensor nodes are received. The unicast messages carry node information of the corresponding sensor nodes, where M is an integer greater than or equal to 1 and less than N.

[0157] In a possible implementation, the process of receiving unicast messages returned by M sensor nodes among the N-1 sensor nodes is consistent with the process of step 105 above, and will not be described in detail here.

[0158] In step 304 , based on the node information of the M sensor nodes, the received signal strengths of the M sensor nodes are determined, and a sensor node whose received signal strength meets the target strength among the M sensor nodes is determined as a second sensor node.

[0159] In a possible implementation, the process of determining the second sensor node is consistent with the process of step 106 above, which will not be described in detail here.

[0160] In step 305, the node information of the second sensor node is sent to the electronic device, and the electronic device establishes a target monitoring network based on the second sensor node.

[0161] In a possible implementation, the process of sending the node information of the second sensor node to the electronic device is consistent with the process of step 107 above, and is not described again here.

[0162] The above method determines the second sensor node based on the node information of M sensor nodes, so that the determined second sensor node is a sensor node with higher performance. Therefore, when a target monitoring network is established based on the second sensor node, the communication error rate of the target monitoring network can be reduced, and thus when the oil and gas pipeline is monitored based on the target monitoring network, the accuracy of the oil and gas pipeline monitoring can be improved.

[0163] Figure 4 The flowchart of the method for establishing a monitoring network provided by the embodiment of the present application is shown. Figure 4 In the process, based on the hardware information of N sensor nodes, the first sensor node is determined, the minimum power level is determined, and the node information of the first sensor node is sent to N-1 sensor nodes other than the first sensor node among the N sensor nodes based on the minimum power level. The N-1 sensor nodes are waited for to reply to the unicast message. If no sensor node replies to the unicast message, the power level continues to increase until a sensor node replies to the unicast message or the power level is increased to the maximum power level.

[0164] If no sensor node responds to the unicast message even after the power level is increased to the maximum, a target monitoring network is established based on the first sensor node. If unicast messages are received from N-1 sensor nodes, the received signal strength of the sensor node that responded to the unicast message is determined based on the unicast message; a second sensor node is determined based on the received signal strength; an indication is sent to the second sensor node, the indication being used to instruct the second sensor node to determine at least one third sensor node; and a target monitoring network is established based on the first sensor node, the second sensor node, and the at least one third sensor node. The target monitoring network is used to monitor the oil and gas pipeline.
