Description

Technical Field

[0001] This application relates to the technical field of communication for oil and gas extraction equipment, and particularly to a communication system and method for a complete set of fracturing equipment. Background Art

[0002] The fracturing operation in oil and gas fields is a complex systematic project. The entire system includes fracturing equipment, sand mixing equipment, instrument equipment, mixing and blending equipment, chemical addition equipment, etc. During the entire operation process, the control and monitoring core is at the instrument equipment end. The command and supervision personnel conduct real-time command and supervision of the entire fracturing operation through the instrument equipment. The operation data and equipment status of all equipment are transmitted and monitored through an industrial Ethernet formed on-site.

[0003] Currently, the mainstream communication methods between complete sets of fracturing equipment all adopt industrial communication cables, that is, wired communication, and the communication method of a ring redundant network. In this way, when only one break point appears in the network, the equipment can still ensure the stability of communication. However, when two or more break points occur, the equipment from the break point to the equipment far from the control center cannot communicate with the control center normally.

[0004] Currently, some operation sites also try to use wireless transmission methods alone for control. Wireless transmission can reduce the workload of laying lines and can also reduce the impact of cable damage on operations. However, the current wireless control method has a slightly poor signal stability. If the wireless network and the wired network are connected together at the same time, it will cause a network storm, directly affecting network paralysis.

[0005] During the fracturing operation, there will be a situation where the fracturing equipment is flexibly grouped for operation. There will be a situation where multiple different brands and configurations of fracturing equipment groups cooperate for operation at the well site. If the network is not handled well, there will be situations such as network conflicts or storms, directly affecting the use of the entire set of fracturing trucks. Summary of the Invention

If the packet loss number of the wireless network is greater than a first number threshold, the switching unit switches the communication mode between the instrument device and the operation device to the wired communication mode.

[0017] In some embodiments, the detection unit is further used to detect the packet loss number of the wired network;

[0018] The switching unit is further used to switch the communication mode between the instrument device and the operation device to the wireless communication mode when the packet loss number of the wired network is greater than a second number threshold and the wireless communication strength of the wireless network is greater than a second preset strength threshold.

[0019] In some embodiments, the detection unit is further configured to detect a wired disconnection fault between the instrument device and the operation device;

[0020] The control module is further configured to control the operation device to perform normal operation when the number of breakpoints of the wired disconnection fault is less than a preset breakpoint number threshold.

[0038] Embodiment 1

[0039] Figure 1 and Figure 2 shows a schematic diagram of the communication system of the fracturing complete equipment according to the embodiment of the present application ( Figure 1 the solid arrows in the figure are wired connections, and the dashed arrows are wireless connections). As Figure 1 and Figure 2 shown, a communication system of a fracturing complete equipment provided by an embodiment of the present application includes an instrument device 10 and operation devices. The instrument device 10 has a control module. The instrument device 10 is connected to at least a part of the operation devices among the operation devices through a wired network, and the instrument device 10 is connected to at least another part of the operation devices among the operation devices through a wireless network.

[0040] The control module is configured to switch the communication mode between the instrument device 10 and the operation devices according to the operation condition of the fracturing complete equipment, wherein the communication mode includes a wired communication mode and a wireless communication mode.

[0041] Among them, the operation equipment includes a fracturing device 20, a sand mixing device 30, a mixing and blending device, a chemical addition device, etc. The instrument device 10 is the control and monitoring core of the fracturing trailer, and is communicatively connected to each operation device. Control instructions are sent to the fracturing device 20, the sand mixing device 30, etc. through communication means, and the operation-related data of the operation devices are monitored and controlled. A main communication terminal (i.e., a main switch) of a wired network can be installed on the instrument device 10. The wired network adopts a ring redundant network to enhance the redundancy performance of the network. Corresponding wired interfaces are installed on the operation devices. The wired network can be an Ethernet. A wireless access point (Access Point, AP terminal) for wireless communication is installed on the instrument device 10. The number of wireless access points can be one or more, which can be determined according to the quantity and location of on-site fracturing and sand mixing devices, etc. Wireless communication clients (Client terminals) are added to operation devices such as the fracturing device 20 and the sand mixing device 30. The wireless network can be Bluetooth, WiFi, ZigBee, 4G, 5G, etc.

[0042] Each operation device can be connected to the instrument device 10 through both a wired network and a wireless network, that is, the communication system adopts a wired and wireless dual-backup function. The control module can perform intelligent analysis and judgment on the network situation of the environment where the operation device is located, and switch between the wired communication mode and the wireless communication mode as needed to ensure reliable, continuous, and stable communication between the operation device and the instrument device 10. The switching of the communication mode by the control module is instantaneous (the time is extremely short, about 10 ms), which is hardly noticeable by users and can provide a good communication experience.

[0043] If other brands or models of operation devices are temporarily added to the operation team, the wired and wireless communication functions can be quickly added, or only the original wired or wireless network functions can be used to quickly access the current network, improving the operation efficiency and having no impact on the networking and application of the existing network at all.

[0044] The wireless access point and the client communicate using a three-layer switching mechanism. Combined with the wired communication between the instrument device 10 and the operation device, it can optimize the communication transmission mechanism between the control-end instrument device 10 (control end, or PC end) and the operation device (device end, or PLC end), realize the scanning visibility and online monitoring of the control end to the device end, and realize the multiplexing of the wired and wireless communication functions. At the same time, by modifying the client ARP processing mechanism mode, the information processing of the client can be reduced, the memory occupancy of the client can be reduced, the communication rate can be increased, the packet loss rate can be reduced, and the communication stability can be ensured. That is, through relevant functional designs, a three-layer switching mechanism is set up in this application, and communication is carried out using a shared channel to realize the multiplexing of the wired and wireless communication functions.

[0045] This application fully combines the advantages of wired and wireless communication methods, enabling both to function simultaneously (where one is by default in a communication standby state, i.e., the wired and wireless communication modes are backup modes for each other), achieving reasonable compatibility between the two, and effectively ensuring stable and reliable communication. For example, the control module is set in the instrument device 10. When there are two or more breaks in the wired network of the operating equipment, the breaks can communicate with the control center (instrument device 10) via the wireless network in a timely manner, ensuring normal communication between the equipment far from the control center and the control center. At the same time, such a communication network architecture also greatly increases the convenience and stability of on-site network construction, solves problems such as network storms caused by the coexistence of the two networks, and also solves the problem of excessive switching time between the two different network modes.

[0046] In specific implementation, this application can also ensure reliable communication by using only the wired connection method according to the on-site operating environment, etc. (for example, when the network layout at the operating site is convenient), or can communicate using only the wireless communication mode (for example, when the transmission distance is short and the signal stability is good).

[0047] In addition to parameters such as the number of operating equipment and the layout position, the operating conditions of the fracturing complete equipment also include the current communication status between the operating equipment and the instrument device 10 (such as whether there are new operating equipment joining the communication and whether the communication network is stable). That is, in the embodiments of this application, the control module can switch to the corresponding communication mode according to the operating conditions of the fracturing complete equipment before the fracturing complete equipment operates, or can also be automatically switched to the corresponding network communication mode in real time according to the operating conditions of the fracturing complete equipment during the operation of the fracturing complete equipment. In specific implementation, the operator of the instrument device 10 can also switch to the corresponding network communication mode manually.

[0048] It can be understood that in the above embodiments, each operating equipment is connected to the instrument device 10 via the wired network and the wireless network respectively, and can switch the required communication mode in a timely manner according to needs, ensuring communication reliability. In a specific embodiment, some operating equipment can be connected to the instrument device 10 only via the wired network, and some operating equipment is connected to the instrument device 10 only via the wireless communication method. That is, using any one of the connection methods for the operating equipment to connect to the instrument device 10 does not affect the communication between the operating equipment and the instrument device 10, making the networking of the fracturing complete equipment more flexible, and can also avoid situations such as network conflicts or storms, ensuring the normal operation of the fracturing complete equipment. For example, as Figure 1 shown, the sand mixing equipment 30 is connected to the instrument device 10 only via the wireless network, while the fracturing equipment 20 is connected to the instrument device 10 via both the wired network and the wireless network.

[0049] The communication system of the fracturing complete set of equipment provided by the embodiments of the present application sets a control module on the instrument equipment 10 of the fracturing complete set of equipment. The control module is connected to at least a part of the operation equipment in the operation equipment through a wired network, and the instrument equipment 10 is connected to at least another part of the operation equipment in the operation equipment through a wireless network. The control module is used to switch the communication mode between the instrument equipment and the operation equipment according to the operation conditions of the fracturing complete set of equipment. Among them, the communication mode includes a wired communication mode and a wireless communication mode. On the basis of the existing pure wired communication mode, the communication mode can be extended to a reliable mutual standby mode of wired and wireless communication, which can avoid situations such as network storms and network conflicts when wired communication and wireless communication exist at the same time, ensure stable and reliable communication during the operation of the fracturing complete set of equipment, and improve the operation efficiency and effect of the fracturing complete set of equipment.

[0050] In some embodiments, the operation equipment includes a plurality of fracturing equipment 20. A main switch for wired communication is provided on the instrument equipment 10, and a wired interface is provided on each fracturing equipment 20. The main switch is connected to the wired interfaces of each fracturing equipment 20 in sequence from beginning to end to form a ring redundant network.

[0051] The fracturing equipment 20 can be flexibly grouped. For example, as Figure 1 shown, in this embodiment, 8 fracturing equipment 20 are set and divided into two groups. The fracturing equipment 20 in the first group of fracturing equipment correspond one by one to the fracturing equipment 30 in the second group of fracturing equipment.

[0052] The main switch on the instrument equipment 10 is connected to the wired interface of the first fracturing equipment (Fracturing 1) in the first group of fracturing equipment. The first fracturing equipment, the second fracturing equipment (Fracturing 2), the third fracturing equipment (Fracturing 3), and the fourth fracturing equipment (Fracturing 4) in the first group of fracturing equipment are connected in sequence through wired interfaces. The fourth fracturing equipment (Fracturing 4) is connected to the eighth fracturing equipment (Fracturing 8) in the second group of fracturing equipment through a wired interface. The eighth fracturing equipment (Fracturing 8), the seventh fracturing equipment (Fracturing 7), the sixth fracturing equipment (Fracturing 6), and the fifth fracturing equipment (Fracturing 5) in the second group of fracturing equipment are connected in sequence. The fifth fracturing equipment (Fracturing 5) is connected to the main switch on the instrument equipment 10 through a wired interface. The main switch, the first group of fracturing equipment (connected in sequence within the group), and the second group of fracturing equipment are connected end to end in sequence to form a ring redundant network. The ring redundant network can ensure that the signal sent on one equipment 20 can be seen by all other equipment on the ring, and send an alarm message in time when the communication is interrupted, ensuring communication reliability.

[0053] In the above embodiment, a ring redundant network is constructed according to the grouping situation of the fracturing equipment 20. In specific implementation, as Figure 2As shown, each fracturing device 20 may not be grouped, and the main switch is connected end to end with each fracturing device 20 to form a ring redundant network.

[0054] In some embodiments, as Figure 1 shown, a first wireless module is provided on the instrument device 10, and a second wireless module for wireless communication with the first wireless module is provided on each of the operation devices. The first wireless module is the wireless access point, and the second wireless module is the client. Each operation device communicates with the instrument device 10 wirelessly, which is convenient and flexible.

[0055] As can be seen from the above, on the premise that the coexistence of wired communication and wireless communication will not cause network storms, based on the existing hardware redundancy (wired redundant network), the present application adds a redundant function of wireless communication to achieve multiple redundancies, effectively improving the reliability and stability of the communication network. In some embodiments, the wireless communication mode is the default communication mode between the instrument device 10 and the operation device, and the control module includes:

[0056] a detection unit for detecting the wireless communication strength of the wireless network;

[0057] a switching unit for switching the communication mode between the instrument device 10 and the operation device according to the wireless communication strength of the wireless network. Wherein, if the wireless communication strength is less than a first preset strength threshold, the switching unit switches the communication mode between the instrument device and the operation device to the wired communication mode.

[0058] When the operation device is operating, it defaults to transmit data and communicate with the instrument device 10 through the wireless network. The detection unit can detect the wireless communication strength of the wireless network in real time and send it to the switching unit; after obtaining the wireless communication strength detected by the detection unit, the switching unit determines whether to switch the communication mode according to the wireless communication strength. When the wireless communication strength is less than the first preset strength threshold, it is determined that the wireless network between the instrument device 10 and the operation device is not smooth, which may cause communication interruption, etc. At this time, the switching unit instantaneously switches the communication mode to the wired communication mode, so that the operation device communicates with the instrument device 10 through the wired network to ensure the reliability of communication; when the wireless communication strength is greater than or equal to the first preset strength threshold, it is determined that the wireless network between the instrument device 10 and the operation device is smooth. At this time, the switching unit does not need to switch the communication mode.

[0059] In specific implementation, the detection unit can detect the wireless communication strength of the first wireless communication module and / or the second wireless communication module to detect the wireless communication strength of the wireless network. When the wireless communication strength of any wireless communication module is detected to be less than the above first preset strength threshold, the switching unit can determine that it is necessary to switch to the wired communication mode.

[0060] In some embodiments, the wireless communication mode is the default communication mode between the instrument device and the operation device, and the control module includes:

[0061] A detection unit, which is used to detect the packet loss quantity of the wireless network;

[0062] A switching unit, which is used to switch the communication mode between the instrument device and the operation device according to the packet loss quantity of the wireless network. Among them, if the packet loss quantity of the wireless network is greater than the first quantity threshold, the switching unit switches the communication mode between the instrument device and the operation device to the wired communication mode.

[0063] In this embodiment, it is still default that the operation device communicates with the instrument device 10 through the wireless network. The switching unit judges whether it is necessary to switch the communication mode according to the packet loss quantity during wireless communication. When the packet loss quantity of the wireless network is greater than the first quantity threshold, it is determined that the wireless communication is unreliable. At this time, the switching unit instantaneously switches the communication mode to the wired communication mode, so that the operation device communicates with the instrument device 10 through the wired network to ensure the reliability of communication; when the packet loss quantity of the wireless network is less than or equal to the first quantity threshold, it is judged that the wireless network communication between the instrument device 10 and the operation device is reliable. At this time, the switching unit does not need to switch the communication mode.

[0064] In some embodiments, the detection unit is further used to detect the packet loss quantity of the wired network;

[0065] The switching unit is further used to switch the communication mode between the instrument device and the operation device when the packet loss quantity of the wired network is greater than the second quantity threshold and the wireless communication strength of the wireless network is greater than the second preset strength threshold.

[0066] The switching between the wired communication mode and the wireless communication mode can be two-way. That is, when there are too many packet losses in the wired communication mode and the wireless signal strength is higher than the second preset strength threshold, the switching unit switches the communication mode to the wireless communication mode, so that the data flow is transmitted wirelessly, fully ensuring the reliability of device communication.

[0067] It should be noted that the control module can be an independent controller arranged on the instrument device 10, or can be a part of the main switch and / or wireless access point, that is, the main switch on the instrument device 10 is connected to the first wireless communication module, and the main switch or the first wireless communication module (or the main switch and the first wireless communication module) realizes the switching of the communication mode.

[0068] In some embodiments, the detection unit is further configured to detect a wired disconnection fault between the instrument device 10 and the working device;

[0069] The control module is further configured to control the working device to perform normal operations when the number of breakpoints of the wired disconnection fault is less than a preset breakpoint number threshold.

[0070] Since in this embodiment, the main switch of the instrument device 10 is connected to each working device through a ring redundant network, when the network encounters a fault, the main switch can quickly (for example, within 300 milliseconds) restore communication. To avoid any shutdown of the working device (for example, frequent shutdowns may damage the device), in this embodiment, the detection unit is used to detect the wired disconnection fault between the instrument device 10 and the working device. When the number of wired breakpoints of the wired disconnection fault does not exceed 2, the working device is controlled to still work normally, and it is timely detected whether the above-mentioned wired breakpoints will affect the normal operation of the working device. When the wired breakpoints affect the normal operation of the working device, the working device is then controlled to stop operating.

[0071] In some embodiments, the instrument device 10 is sequentially connected in series with at least one of the sand mixing device 30, the mixing and blending device, and the chemical addition device through a wired network, and / or

[0072] The instrument device 10 is respectively connected to at least one of the sand mixing device 30, the mixing and blending device, and the chemical addition device through a wireless network.

[0073] There is usually one sand mixing device 30, mixing and blending device, and chemical addition device, etc. Therefore, the above-mentioned sand mixing device 30, mixing and blending device, and chemical addition device can be sequentially connected in series through a wired network to reduce the number of wired network deployments. The sand mixing device 30, mixing and blending device, and chemical addition device can be sequentially connected in series in order, or can be connected end to end to form a ring redundant network.

[0074] The sand mixing device 30, mixing and blending device, and chemical addition device can also be respectively connected to the first wireless communication module on the instrument device 10 through a second wireless communication module provided thereon to realize wireless communication.

[0075] In some embodiments, such as Figure 2As shown, the instrument device 10 also has a PLC (Programmable Logic Controller) and an HMI (touch screen), which can realize the local control of the operation device and fully ensure the communication efficiency of the local control.
