Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire-fighting equipment, in particular to a conveying system with cascade communication function. BACKGROUND

[0002] In actual fire rescue scenes, not only is it necessary to quickly lay fire-fighting pipes for fire extinguishing on site, but also it is necessary to quickly build reliable communication lines on site, so that the external command department can more clearly and definitely master the deployment situation and real-time situation on site, etc., so as to conduct on-site command and dispatch.

[0003] In reality, in a traditional fire rescue scene, wired communication is usually built by separately laying communication lines, but this way not only needs to arrange additional communication lines on site, but also needs to separately perform wiring operation at each communication point (such as a water hose joint), which is very cumbersome and affects the rapid rescue on site. In addition, when the fire-fighting pipe is changed, the position of the communication line also needs to be adjusted accordingly, increasing the workload of the firefighters. In order to improve the rescue efficiency and reduce the burden and workload of the firefighters, in recent years, a common way is to use a long-distance wireless communication module (communication distance is more than 20 meters, usually more than 100 meters) to realize on-site communication, and to use a repeater to enhance the communication signal on site. However, due to the harsh environment and complex situation of the fire scene, the stability and reliability of the long-distance wireless communication signal on site will be seriously affected. For example, the reinforced concrete structure of the scene building will form a natural shielding layer, and the signal will attenuate by 30%-50% every time it penetrates a floor or wall. When rescuing in a multi-story building, the signal strength will drop sharply with the number of walls and floors penetrated by the firefighters entering the internal structure from the outside. Underground, elevator shafts, collapsed buildings, and other enclosed spaces are almost signal blind areas. For another example, the ionized gas produced by the burning on site, the electromagnetic pulse released by the short circuit of the power system and the operation of the rescue equipment (such as a cutting machine and a smoke extractor), will seriously interfere with the communication signal. For another example, the high temperature on site causes air ionization, and the dust particles in the smoke absorb static electricity to form a "plasma cloud" effect, which reflects and scatters the signal, also causing the communication signal to be disorderly. Therefore, how to quickly build a stable and anti-interference communication line on site without increasing the additional burden and workload of the firefighters needs to be solved urgently. SUMMARY

[0004] The first aspect of the present application aims to solve the above technical problems, and provides a conveying system with cascade communication function, which not only does not cause additional burden and workload to the personnel on site, but also can quickly build a stable, reliable and interference-reducing cascade communication line on site.

[0005] A conveying system with cascading communication functionality includes a conveying group, an output group, and terminal equipment for providing conveying power. The terminal equipment is equipped with a first connector module. The conveying group includes a pipeline and a first connector module and a second connector module connected to both ends of the pipeline. A communication line is provided on the pipeline, and the first and second communication modules at both ends of the pipeline are communicatively connected via the communication line. The output group includes an end output device and a second connector module disposed at one end of the end output device. The first and second connector modules each include mutually compatible connectors, which are divided into a first connector and a second connector. The end output device is connected to the pipeline via the second connector. The first connector enables a detachable connection; the second connector enables a detachable connection between pipes; and the second connector enables a detachable connection between pipes and terminal equipment. Of the two mutually compatible connectors, one has an insertion part, and the other has an inner cavity that adapts to the insertion part. The inner cavity houses a first communication module, and the insertion part houses a second communication module. After the first and second connectors are connected, the insertion part is inserted into the inner cavity, which is then closed. The first and second communication modules communicate within the inner cavity, establishing communication between the terminal output device and the pipes, between pipes, and between the pipes and terminal equipment. In this solution, by setting a first connector module in the terminal equipment and configuring a second connector module at one end of the pipeline in the conveying group, the pipeline and the terminal equipment can be connected and communicated synchronously through the cooperation of the first and second connector modules. Similarly, by configuring a first connector module and a second connector module at both ends of the pipeline in the conveying group, adjacent pipelines can be connected and communicated synchronously through the cooperation of the first and second connector modules. Furthermore, by setting a second connector module in the end output device and configuring a first connector module at one end of the pipeline in the conveying group, the end output device and the pipeline can be connected and communicated synchronously through the cooperation of the first and second connector modules. By embedding a communication line within the pipeline and connecting the first and second communication modules at both ends of the pipeline via this communication line, a cascaded communication line from the end output device to the terminal equipment can be quickly established on-site. This allows for signal transmission along the conveying system via cascaded communication, achieving more stable and reliable communication. Moreover, this cascaded communication line can be established simultaneously with the laying of the conveying system, without imposing additional burdens or work on firefighters on-site, making it extremely convenient.By configuring an inner cavity and an insertion part on each of the two mating connectors, and placing the first and second communication modules in the inner cavity and insertion part respectively, during assembly, after the first and second connectors are connected, the insertion part is inserted precisely into the inner cavity, which is then completely sealed. This allows the first and second communication modules to communicate within the inner cavity. This design, on the one hand, reduces the distance between the first and second communication modules, strengthens anti-interference capabilities, and makes field communication smoother and more stable. On the other hand, the connector shell acts as a shield for the first and second communication modules, enclosing them internally and ensuring point-to-point communication between the first and second connectors. This effectively prevents interference and influence from the field environment, and also effectively prevents signal crosstalk. Consequently, it effectively improves the reliability and stability of communication between the first and second communication modules, facilitating the establishment of stable, reliable, and interference-resistant cascaded networks. This makes it easier for personnel to quickly build stable, reliable, and interference-reducing cascaded communication lines on-site.

[0006] Preferably, the second connector of the second connector module has an insertion part, and the first connector of the first connector module has an inner cavity that adapts to the insertion part. This facilitates faster on-site installation of the conveying system.

[0007] A second aspect of this invention addresses the problem of improving the communication reliability between the first connector module and the second connector module. Further, the first and second communication modules employ mutually compatible wireless communication modules. When the first connector and the second connector are connected, the first communication module is within the communication range of the second communication module, and vice versa. In this solution, by configuring the first and second communication modules as mutually compatible wireless communication modules, communication can be established synchronously when the terminal output device is connected to a conduit, when conduits are connected to each other, and when a conduit is connected to a terminal device. This eliminates the need for strict contact between the first and second communication modules, effectively reducing the requirements for manufacturing and assembly precision, and facilitating the establishment of stable and reliable communication between the first and second communication modules.

[0008] Preferably, the wireless communication module includes an NFC communication module, an infrared communication module, an ultrasonic communication module, a Bluetooth module, or a Zigbee communication module. This facilitates a more stable and interference-resistant communication line between the first connector and the second connector.

[0009] Preferably, after the first connector and the second connector are connected, the distance between the first communication module and the second communication module is less than or equal to 10cm. This allows the first communication module and the second communication module to conduct more stable and reliable communication within the enclosed cavity, effectively improving anti-interference and anti-signal crosstalk capabilities.

[0010] A third aspect of this invention addresses the issues of simplified structure and improved versatility. Further, a flow channel is constructed within the connector, with an inner cavity formed at one end of one connector and communicating with the flow channel within that connector. An insertion portion adapted to the inner cavity is constructed at one end of the other connector, with the flow channel of that connector penetrating the insertion portion. After the two connectors are connected, their flow channels are interconnected. In this solution, by constructing a flow channel within the connector, the flow channel in the connector with the inner cavity is configured to communicate with the inner cavity, while in the connector with the insertion portion, the flow channel is configured to penetrate the insertion portion. Since the first communication module and the second communication module are respectively located in the inner cavity and the insertion portion, after the two connectors are connected, they can communicate with each other through the flow channel, while the first and second communication modules communicate with each other within their respective inner cavities. The overall structure of the connector is simplified and compact, and it can be applied to various existing connectors, thereby improving versatility.

[0011] Preferably, the inner diameter of the flow channel is smaller than the inner diameter of the inner cavity, and an annular stepped surface is formed between the inner cavity and the flow channel. After the first connector and the second connector are connected, the end of the insertion part corresponds to the stepped surface.

[0012] Preferably, the first communication module is disposed on the stepped surface, and the second communication module is disposed at or within the end of the insertion part; or, the first communication module is disposed on the inner side of the cavity, and the second communication module is disposed on the outer side of the insertion part. This facilitates a more stable, reliable, and interference-resistant communication between the first and second communication modules.

[0013] Preferably, the first connector and the second connector adopt mutually compatible KDK type card-type fire protection interfaces.

[0014] Furthermore, the conveying assembly also includes a first processor and a first power supply. The first processor is disposed at a first connector and / or a second connector at both ends of the pipeline, and a first communication module and a second communication module are respectively connected to the first processor. The first power supply is disposed at the first connector and / or the second connector at both ends of the pipeline, and the first power supply includes a battery for storing electrical energy, which powers the electrical components in the conveying assembly. This facilitates the realization of modular, integrated, and intelligent conveying assemblies, promotes rapid on-site assembly, improves efficiency, and is particularly beneficial for shortening rescue time in the firefighting field.

[0015] Furthermore, the output group also includes a second processor and a second power supply. The second communication module of the second connector module in the output group is connected to the second processor. The second power supply includes a battery for storing electrical energy, which powers the electrical components in the output group. This design facilitates modular, integrated, and intelligent output groups, enabling rapid on-site assembly, improving efficiency, and especially shortening rescue time in the firefighting field.

[0016] Preferably, the terminal device is further provided with a conveying power source, which is connected to the first connector in the first connector module.

[0017] Furthermore, the terminal device also includes a third processor and a third power supply. The first communication module on the terminal device is connected to the third processor, and the battery is used to power the electrical components on the terminal device. This facilitates the realization of modular, integrated, and intelligent terminal devices, promotes rapid on-site assembly, improves efficiency, and is particularly beneficial in shortening rescue time in the fire protection field.

[0018] The fourth aspect of this invention addresses the problem of rapidly achieving cascaded networking at the water distributor. Further, it includes a water distributor with a second connector module at one end and at least two first connector modules at the other end. The first connectors in each first connector module are connected to the second connectors in the second connector modules. Valves for controlling on / off switching are provided between the second connectors and each first connector in the water distributor. The water distributor is connected in series between two delivery groups, and the water distributor and the pipelines are detachably connected through the cooperation of the second and first connectors. This allows the water distributor to be quickly assembled between two adjacent pipelines and easily cascaded with them. It not only enables communication networking during the assembly of the water distributor but also facilitates the rapid establishment of cascaded communication lines including the water distributor for step-by-step signal transmission.

[0019] Furthermore, the water distributor also includes a fourth processor and a fourth power supply. Each of the first and second communication modules on the water distributor is connected to the fourth processor. The fourth power supply includes a battery for storing electrical energy, which powers the various electrical components within the water distributor. This design facilitates modular, integrated, and intelligent water distributors, enabling rapid on-site assembly, improving efficiency, and especially shortening rescue time in the firefighting field.

[0020] Preferably, the terminal equipment is a fire truck; the pipeline in the delivery group is a fire hose; and the end output device in the output group is a water gun.

[0021] The fifth aspect of this invention addresses the problem of sending information more conspicuously to on-site personnel from off-site locations. Further, the conveying group includes a light-emitting component, which is disposed within the conduit and / or connector of the conveying group. The light-emitting component is connected to a first processor, which controls the state of the light-emitting component. In practical use, the first processor can control the state of the light-emitting component in the conduit via cascaded communication to form specific light signals. This allows for more conspicuous communication of specific information through changes in the state of the light-emitting component, enabling off-site personnel to send information more conspicuously to on-site personnel via cascaded communication, effectively overcoming the drawbacks of using walkie-talkies for communication.

[0022] The sixth aspect of this invention addresses the problem of enabling frontline personnel to more conspicuously send information to other personnel on-site. Furthermore, the output group includes an operating component connected to a second processor, capable of adjusting the state of the light-emitting components. In case of an emergency at the frontline, frontline personnel can control the state of the light-emitting components in each transmission group through the operating component, forming specific light signals. This allows for more conspicuous communication of specific information through changes in the state of the light-emitting components, enabling frontline personnel to send information more clearly to other personnel at the back end via cascaded communication, effectively overcoming the drawbacks of using walkie-talkies for communication.

[0023] Compared with existing technologies, the present invention provides a transmission system with cascaded communication function, which not only does not impose additional burden and work on on-site personnel, but also can quickly set up a stable, reliable cascaded communication line on-site that can effectively reduce interference.

Detailed Implementation Example 1

[0043] This embodiment provides a conveying system, including a terminal device 4, multiple conveying groups 2 arranged in series, and an output group 1, wherein, as shown... Figures 1-3 As shown, the conveying group 2 includes a pipeline 20 for conveying and connector modules located at both ends of the pipeline 20 and adapted to each other. Each connector module includes a connector and a communication module located at the connector. The connectors of the two connector modules can be connected and disconnected, and the communication modules of the two connector modules are adapted to each other and can establish communication with the communication modules of adjacent connector modules, enabling communication between the two connected conveying groups 2. For ease of description, in this embodiment, the connector modules at both ends of the pipeline 20 are referred to as the first connector module 21 and the second connector module 24, respectively. Correspondingly, the first connector module 21 includes a first connector 22 and a first communication module 23 located at the first connector 22, and the second connector module 24 includes a second connector 25 and a second communication module 26 located at the second connector 25. Figure 3 As shown, in implementation, the first connector 22 and the second connector 25 are respectively disposed at both ends of the pipeline 20. The two ends of the pipeline 20 are respectively connected to the first connector 22 and the second connector 25. The first connector 22 is adapted to the second connector 25 and can be detachably connected to the second connector 25. The first communication module 23 and the second communication module 26 are adapted to each other and can establish mutual communication.

[0044] Similarly, in this embodiment, the output group 1 includes an end output device 11 and a second connector module 24 disposed at one end of the end output device 11. Specifically, the second connector module 24 on the end output device 11 includes a second connector 25 connected to and communicating with one end of the end output device 11 and a second communication module 26 disposed on the second connector 25, such as... Figure 4 As shown.

[0045] In this embodiment, the terminal device 4 is provided with a first connector module 21. Specifically, the first connector module 21 on the terminal device 4 includes a first connector 22 and a first communication module 23 disposed on the first connector 22, such as... Figure 5 As shown.

[0046] During assembly, such as Figure 8 and Figure 9 As shown, output group 1 and conveying group 2 can be detachably connected by the cooperation of second connector 25 and first connector 22, realizing the connection between terminal output device 11 and pipeline 20, and can communicate with each other by the cooperation of second communication module 26 and first communication module 23; similarly, conveying group 2 and conveying group 2 can be detachably connected by the cooperation of second connector 25 and first connector 22, realizing the connection between pipeline 20, and can communicate with each other by the cooperation of second communication module 26 and adjacent first communication module 23; conveying group 2 and terminal device 4 can be detachably connected by the cooperation of second connector 25 and first connector 22, realizing the connection between pipeline 20 and terminal device 4, and can communicate with each other by the cooperation of second communication module 26 and first communication module 23, so that a communication line along the conveying line can be built simultaneously while quickly building a conveying line connecting terminal device 4.

[0047] It is understandable that, depending on the application, the terminal device 4 can have various implementation methods. For example, when this conveying system is applied to the fire protection field, it is essentially a fire conveying system. The terminal device 4 can be a fire hydrant or a fire truck. Correspondingly, the pipeline 20 can be a fire hose, the connector can be a fire hose coupling, and the terminal output device 11 can be a water gun to output the extinguishing agent. For example, if the terminal device 4 is a fire truck, the fire truck is equipped with a conveying power source connected to the first connector 22 on the terminal device 4. The conveying power source can be a pump or other equipment. When this conveying system is applied to the agricultural irrigation field, the terminal device 4 can be a water pump, the pipeline 20 can be a water pipe, and the terminal output device 11 can be a drip irrigation head, a micro-sprinkler head (such as a misting device), etc. When this conveying system is applied to the industrial field, the terminal device 4 can be a conveying pump to provide conveying power, the pipeline 20 can be a common pipe, and the terminal device 4 can be a misting nozzle, etc. As an example, in this embodiment, the terminal device 4 is a fire truck. The fire truck is also equipped with a delivery pump and a storage space for containing extinguishing agents. The delivery pump is connected to the storage space, which stores extinguishing agents, such as water, foam mixture, or other extinguishing agents. One or more first connector modules 21 can be configured on the side of the fire truck, and the first connector 22 in each first connector module 21 is connected to the delivery pump. Of course, it is understood that valves are also configured on the connection path between each first connector module 21 and the delivery pump. In this embodiment, the pipeline 20 can be an existing water pipe or hose. For example, the pipeline 20 uses a fire hose. The length of a fire hose is usually 20 meters. Two fire hoses are connected by the cooperation of the first connector 22 and the second connector 25 to achieve longer-distance delivery.

[0048] In implementation, the first connector 22 and the second connector 25 can be paired connectors using existing technology, and the first connector 22 and the second connector 25 are respectively constructed with mutually compatible first and second fastening structures, so that the first connector 22 and the second connector 25 can be detachably connected through the cooperation of the first and second fastening structures. In implementation, the first and second fastening structures can be implemented using existing technology, for example, the first connector 22 and the second connector 25 can respectively adopt the female and male interfaces of a card-type fire hose coupling, etc., which will not be illustrated here.

[0049] In implementation, one of the connectors (first connector 22 or second connector 25) is configured with an insertion part 6, such as... Figure 2 and Figure 3 As shown, correspondingly, another connector (second connector 25 or first connector 22) is constructed with an inner cavity 5 adapted to the insertion portion 6, such as... Figure 1 and Figure 3As shown; for ease of description, as an example, in this embodiment, the second connector 25 of the second connector module 24 is configured with an insertion portion 6, and the first connector 22 of the first connector module 21 is configured with an inner cavity 5 adapted to the insertion portion 6, as shown. Figure 6 As shown; the first communication module 23 in the first connector module 21 is disposed in the inner cavity 5, and the second communication module 26 in the second connector module 24 is disposed in the insertion part 6. After the first connector 22 and the second connector 25 are connected, the insertion part 6 is inserted into the inner cavity 5, and the inner cavity 5 is closed, as shown. Figure 6 and Figure 7 As shown, at this time, the first communication module 23 and the second communication module 26 are both in the inner cavity 5, and the first communication module 23 and the second communication module 26 can communicate with each other in the inner cavity 5, thereby establishing cascaded communication between the end output device 11 and the pipeline 20, between pipelines 20 and each other, and between pipeline 20 and the terminal device 4.

[0050] More specifically, in implementation, the insertion part 6 and the inner cavity 5 can be configured in various ways. For example, in one embodiment, the insertion part 6 includes a mounting base 64 constructed on the second connector 25 but offset from the center of the second connector 25. The mounting base 64 has a mounting hole. The second communication module 26 can be a communication plug disposed in the mounting hole. The communication plug is fixed to the second connector 25 through the mounting hole. The communication plug is coaxial with the mounting base 64 and can be arranged parallel to the second connector 25. Correspondingly, the inner cavity 5 can be constructed on the first connector 22 but offset from the center of the first connector 22. The first communication module 23 is a communication socket adapted to the communication plug. The communication socket is located within the inner cavity 5. When connecting the first connector 22 and the second connector 25, the communication plug is simultaneously inserted into the communication socket. When the first connector 22 and the second connector 25 are in place, the mounting base 64 seals the inner cavity 5 for waterproofing. Simultaneously, the communication plug and the communication socket contact and communicate within the inner cavity 5, enabling wired communication between the first connector 22 and the second connector 25. This allows for the rapid establishment of stable communication between the first connector 22 and the second connector 25. It is understood that, in implementation, both the communication plug and the communication socket can be implemented using existing technologies, which will not be elaborated upon here.

[0051] For example, in another implementation, such as Figure 10 and Figure 11As shown, the insertion part 6 includes a mounting base 64 offset from the center of the second connector 25. The second communication module 26 is disposed on the mounting base 64 and protrudes outward from the end face of the second connector 25 (the surface perpendicular to the central axis of the second connector 25 is called the end face of the second connector 25, wherein the end face located at the end of the second connector 25 is called the outer end face 6, which will not be described again later). Correspondingly, the inner cavity 5 can also be constructed at a position offset from the center of the first connector 22. The position of the inner cavity 5 is adapted to the insertion part 6, and the first communication module 23 is disposed in the inner cavity 5. When the first connector 22 and the second connector 25 are connected, the insertion part 6 is simultaneously inserted into the inner cavity 5, so that the second communication module 26 is simultaneously inserted into the inner cavity 5. When the first connector 22 and the second connector 25 are connected in place, the mounting base 64 of the insertion part 6 exactly closes the inner cavity 5, and the second communication module 26 is also located in the inner cavity 5. Figure 10 As shown, at this time, both the first communication module 23 and the second communication module 26 are located in the inner cavity 5. The first communication module 23 and the second communication module 26 do not need to contact each other. The first communication module 23 and the second communication module 26 can use mutually compatible wireless communication modules, so that the first communication module 23 and the second communication module 26 in the inner cavity 5 can communicate with each other to realize wireless communication, thereby quickly establishing communication between the first connector 22 and the second connector 25. Since the first connector 22 and the second connector 25 establish wireless communication in the inner cavity 5, on the one hand, the distance between the first communication module 23 and the second communication module 26 is smaller, and the on-site communication is smoother and more stable; on the other hand, it can not only prevent the interference of the on-site environment on the communication, but also realize one-to-one (point-to-point) communication between the first connector 22 and the second connector 25, avoiding signal crosstalk caused by communication with other communication modules, thus facilitating the realization of a more stable and reliable serial cascaded network.

[0052] For example, in this embodiment, the connector module's connectors (including the first connector 22 and the second connector 25) have a flow channel 53 for conveying liquid, and the inner cavity 5 is constructed at one end of one of the connectors (such as the first connector 22). Figures 1-3 As shown, the inner cavity 5 is connected to the flow channel 53 within the connector. During implementation, the inner cavity 5 is preferably coaxial with the flow channel 53 within the connector. Correspondingly, the insertion portion 6 is constructed at one end of another connector (such as the second connector 25), and the flow channel 53 within that connector penetrates the insertion portion 6. Figure 6As shown; in the end output device 11, the flow channel 53 in the second connector 25 is connected to the end output device 11; at both ends of the pipeline 20, the flow channel 53 in the first connector 22 is connected to the pipeline 20, and the flow channel 53 in the second connector 25 is also connected to the pipeline 20, thereby realizing the connection between the first connector 22 and the second connector 25 at both ends of the pipeline 20; in the terminal device 4, the flow channel 53 in the second connector 25 is connected to the terminal device 4. During assembly, after the first connector 22 and the second connector 25 are connected, the insertion part 6 is inserted into the inner cavity 5, and the inner cavity 5 is closed, so that the flow channel 53 in the first connector 22 is connected to the flow channel 53 in the second flow channel 53, as shown. Figure 6 As shown, this enables the connection between the first connector 22 and the second connector 25 for conveying operations. In this embodiment, the first communication module 23 and the second communication module 26 can be mutually compatible wireless communication modules. Within the inner cavity 5, the first communication module 23 is within the communication range of the second communication module 26, and the second communication module 26 is also within the communication range of the first communication module 23. This allows the first communication module 23 and the second communication module 26 within the inner cavity 5 to communicate with each other and achieve wireless communication, thus enabling rapid communication between the first connector 22 and the second connector 25. Because the first connector 22 and the second connector 25 establish wireless communication within the inner cavity 5, on the one hand, the distance between the first communication module 23 and the second communication module 26 is smaller, resulting in smoother and more stable on-site communication; on the other hand, it can prevent interference from the on-site environment, especially when both the first connector 22 and the second connector 25 are made of metal. The first connector 22 and the second connector 25 can act as shields for the first communication module 23 and the second communication module 26, enclosing them internally. Figure 6 and Figure 7 As shown, this not only further prevents interference and impact of the on-site environment on communication, but also further improves the reliability and stability of communication between the first communication module 23 and the second communication module 26; it also prevents the wireless signal in the inner cavity 5 from being transmitted to the outside, avoids signal crosstalk problems caused by communication with other communication modules, and ensures one-to-one (point-to-point) communication between the first connector 22 and the second connector 25, thereby facilitating the realization of a more stable and reliable serial cascaded network, so as to quickly build a more interference-resistant and stable communication line 28, without increasing the additional burden on personnel.

[0053] In specific implementation, such as Figure 6 and Figure 7As shown, the second communication module 26 can preferably be disposed on the outer side, outer end face 6, or inside the outer end face 6 of the insertion part 6, while the first communication module 23 can be disposed in the corresponding position within the inner cavity 5. As a more specific example, in implementation, the first connector 22 and the second connector 25 can each adopt a mutually compatible KDK type card-type fire extinguisher interface. For example, when the first connector 22 adopts the female interface of the KDK type card-type fire extinguisher interface, such as... Figure 1 and Figure 2 As shown, the second connector 25 adopts the male connector of a KDK type card-type fire hose coupling; one end of the female connector has an inner cavity 5, which is connected to a flow channel 53. The inner diameter of the flow channel 53 is smaller than the inner diameter of the inner cavity 5, thus forming an annular stepped surface 51 between the inner cavity 5 and the flow channel 53, as shown. Figure 1 and Figure 6 As shown; the male interface has an insertion part 6 that communicates with its own flow channel 53. The insertion part 6 has a cylindrical structure, as shown in the figure. The first fastening structure includes a spring retaining ring 52 that fits the insertion part 6, as shown in the figure. Figure 1 and Figure 6 As shown, the spring retaining ring 52 is arranged circumferentially within the inner cavity 5; correspondingly, the second fastening structure includes a step 62 constructed on the outer surface of the insertion portion 6 and adapted to the spring retaining ring 52, as shown. Figure 2 and Figure 6 As shown; during connection, the insertion part 6 of the male interface is inserted into the inner cavity 5 of the female interface, and the spring retaining ring 52 is engaged at the step 62, as shown. Figure 6 As shown, this achieves a detachable connection between the male and female interfaces. At this time, the male interface abuts against the female interface, sealing the inner cavity 5, and the outer end face 6 of the insertion part 6 corresponds to the stepped surface 51, as shown. Figure 6 As shown, the outer surface of the insertion part 6 corresponds to the inner surface of the inner cavity 5. The insertion part 6 is usually also fitted with an unlocking element 63 for unlocking. In implementation, the first communication module 23 can be disposed (e.g., embedded) in the stepped surface 51, such as... Figure 3 and Figure 6 As shown, correspondingly, the second communication module 26 can be preferentially disposed on the outer end face 6 of the insertion part 6, such as... Figure 3 and Figure 6As shown, this arrangement brings the first communication module 23 closer to the second communication module 26. Alternatively, in implementation, the second communication module 26 can also be positioned on the outer surface of the insertion portion 6, achieving mutual communication. Furthermore, in implementation, the first communication module 23 can also be positioned on the inner surface of the cavity 5, and correspondingly, the second communication module 26 can be preferentially positioned on the outer surface of the insertion portion 6, bringing the first communication module 23 closer to the second communication module 26. Of course, the second communication module 26 can also be positioned on the outer end face 6 of the insertion portion 6. In this embodiment, after the first connector 22 and the second connector 25 are connected, the distance between the first communication module 23 and the second communication module 26 can be less than or equal to 10 cm, enabling stable and reliable communication between the first communication module 23 and the second communication module 26 within the closed cavity 5. Figure 6 As shown.

[0054] It is understandable that when the first connector 22 adopts the male interface of a KDK type card-type fire extinguisher connector, and the second connector 25 adopts the female interface of a KDK type card-type fire extinguisher connector, the inner cavity 5 is constructed in the second connector 25, and the insertion part 6 is constructed in the first connector 22, achieving the same technical effect. Specific examples will not be provided here. In a more complete embodiment, the connectors (including the first connector 22 and the second connector 25) also have a connecting part 29, such as... Figure 1 and Figure 3 As shown, in the conveying group 2, the connector 29 can be constructed as a threaded structure, through which the flow channel 53 passes to connect to the pipeline 20; in the output group 1 and the terminal device 4, the connector 29 can preferably be constructed as a cylindrical structure, through which the flow channel 53 passes, and the connector connects to the end output device 11 or the terminal device 4, such as... Figure 4 and Figure 5 As shown.

[0055] Since the first communication module 23 and the second communication module 26 employ mutually compatible wireless communication modules, in implementation, these wireless communication modules can be NFC (Near Field Communication), infrared, Bluetooth, ultrasonic, Zigbee, Wi-Fi, NB-IoT, or LoRa modules, etc. To achieve better communication performance, in implementation, the first communication module 23 is preferably disposed (e.g., embedded) in the stepped surface 51, and the second communication module 26 is preferably disposed on the outer end face 6 of the insertion part 6, such as... Figure 6As shown, this not only further reduces the distance between the first communication module 23 and the second communication module 26, but also allows the first communication module 23 to face the second communication module 26 directly, thus achieving better communication performance. In some applications, when it is necessary to ensure that the first communication module 23 and the second communication module 26 are strictly aligned, the first connector 22 and the second connector 25 are also constructed with mutually compatible first and second positioning parts. The cooperation of the first and second positioning parts ensures that the first connector 22 and the second connector 25 are always connected in a fixed orientation, thus ensuring that the first communication module 23 and the second communication module 26 are precisely aligned. For example, the first positioning part can be a positioning groove constructed in the first connector 22, and correspondingly, the second positioning part can be a positioning protrusion constructed in the second connector 25. The positioning protrusion fits the positioning groove. During assembly, ensuring that the positioning protrusion is aligned with the positioning groove guarantees that the first communication module 23 is aligned with the second communication module 26. When the first connector 22 and the second connector 25 are connected, the positioning protrusion is inserted into the positioning groove, preventing relative rotation between the first connector 22 and the second connector 25, thus ensuring that the first communication module 23 is always aligned with the second communication module 26. It can be understood that constructing the first positioning part as a positioning protrusion and the second positioning part as a positioning groove can achieve the same effect, which will not be elaborated further here.

[0056] In actual use, water may fill the inner cavity 5. However, according to previous tests, water filling the inner cavity 5 will not affect the normal passage of the first communication module 23 and the second communication module 26. In implementation, it is only necessary to ensure the waterproof sealing of the first communication module 23 and the second communication module 26. For example, in implementation, a layer of glue can be applied to the surface of the first communication module 23 and the second communication module 26 respectively, which can achieve the effect of waterproof sealing without affecting the communication between the two. Moreover, the process is simple and low in cost.

[0057] In this embodiment, since communication needs to be established between the first connector 22 and the second connector 25 at both ends of the pipeline 20, and wireless communication cannot be established between the first connector 22 and the second connector 25 at both ends of the pipeline 20 to prevent problems such as on-site interference and signal crosstalk, a further embodiment of the pipeline 20 is also provided with a communication line 28, which is arranged along the length of the pipeline 20, such as... Figure 3As shown, the first communication module 23 and the second communication module 26 at both ends of the pipeline 20 are connected by the communication line 28, enabling wired communication. This not only transmits signals from one end of the pipeline 20 to the other, but also provides stable and interference-resistant transmission. In implementation, the communication line 28 can be embedded within the pipeline 20, with taps leading from both ends for wiring, thus integrating the communication line 28 with the pipeline 20. This allows for simultaneous installation of the communication line 28 while laying the pipeline 20, making the process convenient and efficient without requiring additional personnel intervention. For example, the pipeline 20 uses a fire hose. Existing fire hoses typically consist of a lining forming the delivery channel and a braided layer covering the outside of the lining. The braided layer primarily enhances the hose's wear resistance and load-bearing capacity, protecting the inner lining and making the hose more durable. The communication line 28 can be placed within the lining, between the lining and the braided layer, or woven into the braided layer, all achieving the purpose of securing the communication line 28.

[0058] To enable better coordination between the first communication module 23 and the second communication module 26 at both ends of the pipeline 20 for signal transmission, in practice, the first connector 22 and / or the second connector 25 at both ends of the pipeline 20 are also equipped with a first processor 27, such as... Figure 9 As shown, the first processor 27 is mainly used to coordinate with the first communication module 23 and the second communication module 26 to process and transmit data. The first communication module 23 and / or the second communication module 26 are connected to the first processor 27 through the communication line 28 to ensure that the first communication module 23 and the second communication module 26 at both ends of the pipeline 20 can communicate smoothly with each other. In implementation, the first processor 27 can be set on the first connector 22. The first communication module 23 on the first connector 22 is connected to the first processor 27. One end of the communication line 28 is connected to the first processor 27. The communication line 28 is arranged along the length of the pipeline 20. The other end of the communication line 28 is connected to the second communication module 26 on the second connector 25, such as... Figure 3As shown. For example, the first processor 27 can be located on the second connector 25, with the second communication module 26 on the second connector 25 connected to the first processor 27. One end of the communication line 28 is connected to the first processor 27, and the communication line 28 is arranged along the length of the pipe 20. The other end of the communication line 28 is connected to the first communication module 23 on the first connector 22, achieving the same effect. Alternatively, the first connector 22 and the second connector 25 at both ends of the pipe 20 can each be equipped with a first processor 27, with the first communication module 23 and the second communication module 26 respectively connected to their corresponding first processor 27. The two first processors 27 can be connected via the communication line 28 located in the pipe 20. In implementation, the first processor 27 can be an MCU (microcontroller, such as STM32 series, ATmega series, 51 microcontroller, etc.), an embedded first processor 27 (such as ARM Cortex-A series), or a PLC, etc.

[0059] In a more refined embodiment, the first connector 22 and / or the second connector 25 at both ends of the conduit 20 are further provided with a first power source, which includes a battery 33 for storing electrical energy, such as... Figure 3 and Figure 9 As shown, battery 33 is connected to electrical components such as the first processor 27, the first communication module 23, and the second communication module 26 in the delivery group 2 to provide power. Battery 33 can be embedded in the first connector 22 or the second connector 25. Alternatively, in practice, the first power source may also include a housing 32, in which battery 33 and the first processor 27 can be housed. The housing 32 is then fixed to the first connector 22 or the second connector 25. Figure 3 As shown; battery 33 can preferably be located on the same connector as the first processor 27. The electrical components in the other connector can be connected to battery 33 via a power supply line embedded in conduit 20. For example, battery 33 and the first processor 27 are both located on the first connector 22, conduit 20 has an embedded power supply line, one end of which is connected to battery 33 or the first processor 27, and the other end is connected to the second communication module 26 on the second connector 25. Figure 3 As shown, this is to provide power to the second connector 25. Similarly, in implementation, the power supply line can be located inside the lining, between the lining and the braided layer, or woven into the braided layer; furthermore, the communication line 28 and the power supply line can be integrated into one line, allowing the entire conveyor assembly 2 to constitute an independent intelligent unit. Accordingly, the first power supply also includes a charging module connected to the battery 33 to fully charge it before use, so that the first connector 22, the water hose, and the second connector 25 in the conveyor assembly 2 have a sufficiently long standby time, such as 6 hours, 8 hours, 12 hours, etc.

[0060] In this embodiment, output group 1 is also configured with a second processor 12, such as Figure 4 andFigure 9 As shown, the second communication module 26 of the second connector module 24 in output group 1 is connected to the second processor 12. Correspondingly, output group 1 is also equipped with a second power supply, which includes a battery 33 for storing electrical energy. The battery 33 is connected to the second processor 12, the second communication module 26 on the terminal output device 11, and other electrical components to supply power to the various electrical components on the terminal output device 11. Similarly, the battery 33 can be embedded in the terminal output device 11, or a housing 32 can be provided for the second power supply. Both the battery 33 and the second processor 12 can be housed within the housing 32, which is then fixed to the terminal output device 11. Figure 4 As shown, the second processor 12 can be connected to the second communication module 26 on the end output unit 11 via wire 34, enabling the entire output group 1 to form an independent intelligent unit. Similarly, in implementation, the second processor 12 can be an MCU, an embedded first processor 27, or a PLC, etc. Correspondingly, the second power supply also includes a charging module connected to the battery 33 to fully charge it before use, so that the output group 1 has a sufficiently long standby time, such as 6 hours, 8 hours, 12 hours, etc.

[0061] In this embodiment, the terminal device 4 is also equipped with a third processor 41, such as Figure 5 and Figure 9 As shown, the first communication module 23 on the terminal device 4 is connected to the third processor 41 via a wire 34. The terminal device 4 is also equipped with a third power supply to power the electrical components on the terminal device 4. Furthermore, in a more complete embodiment, the terminal device 4 is also equipped with a display screen connected to the third processor 41 to display relevant information from the site. Additionally, the terminal device 4 is equipped with a communication module 42 connected to the third processor 41 to communicate with a host computer, cloud platform, or remote command center, enabling remote monitoring, dispatching, and management functions. This allows the entire terminal device 4 to form an independent intelligent unit. Similarly, in implementation, the third processor 41 can be an MCU, an embedded first processor 27, or a PLC, etc.

[0062] In practical use, multiple required pipelines 20 can be connected in series on the terminal device 4 according to the actual needs of the site, and the end output device 11 can be connected to the first pipeline 20, such as... Figure 8As shown, not only can a conveying line from terminal device 4 to output group 1 be quickly formed for conveying operations, but also a cascaded communication line 28 from end output device 11 through pipeline 20 to terminal device 4 can be simultaneously built while the conveying line is being formed. In actual use, information from the front end (such as end output device 11) can be stably and without interference transmitted to the rear terminal device 4 or remote command center through the cascaded communication line 28. For example, the signals or collected data from the front end can be transmitted to the back end step by step; information from the back end (such as terminal device 4 or remote command center) can be stably and without interference transmitted forward through terminal device 4 and pipeline 20 to the front pipeline 20 or end output device 11. For example, the dispatch signals or warning signals from the back end can be transmitted forward step by step to the front end. Example 2

[0063] Based on Example 1, the conveying system provided in this example also includes a water distributor 3, such as... Figure 12 As shown, one end of the water distributor 3 is provided with a second connector module 24, and the other end is provided with at least two first connector modules 21. The first connector 22 in each first connector module 21 is connected to the second connector 25 in the second connector module 24, and valves for controlling the on / off state are respectively provided between the second connector 25 in the water distributor 3 and each first connector 22. In implementation, the number of first connector modules 21 configured in the water distributor 3 can be determined according to actual needs. Two or three first connector modules 21 can be configured preferentially to form a two-way water distributor 3 and a three-way water distributor 3.

[0064] During implementation, the water distributor 3 is also equipped with a fourth processor 31, such as... Figures 12-14 As shown, each of the first communication modules 23 and the second communication modules 26 on the water distributor 3 is connected to the fourth processor 31, so that the signal received by the first communication module 23 can be transmitted to the second communication module 26 via the fourth processor 31, and the signal received by the second communication module 26 can also be transmitted to the first communication module 23 via the fourth processor 31.

[0065] In a more refined implementation, the water distributor 3 is also equipped with a fourth power source, such as... Figures 12-14 As shown, the fourth power source includes a battery 33 for storing electrical energy. The battery 33 is connected to the fourth processor 31, the first communication module 23, and the second communication module 26, respectively, to supply power to the various electrical components in the water distributor 3. In implementation, the battery 33 can be embedded within the housing of the water distributor 3, or it can be housed in a casing 32. Both the battery 33 and the fourth processor 31 can be housed within this casing 32, which is then fixed to the water distributor 3. Figure 12 and Figure 13As shown, this makes the entire water distributor 3 a self-contained intelligent unit. Similarly, in implementation, the fourth processor 31 can be an MCU, an embedded first processor 27, or a PLC, etc.

[0066] In practical use, the water distributor 3 is usually set between two conveying groups 2. It can not only connect the two conveying groups 2, but also play the roles of water distribution and flow control. In implementation, the first connector 22 at one end of the water distributor 3 is connected to the second connector 25 at one end of one conveying group 2, and communication is established through the cooperation of the first communication module 23 and the second communication module 26. At the same time, the second connector 25 at the other end of the water distributor 3 is connected to the first connector 22 at one end of another conveying group 2, and communication is established through the cooperation of the second communication module 26 and the first communication module 23. Thus, the two conveying groups 2 can communicate with each other through the water distributor 3. This is beneficial for building a cascaded communication line 28 from the end output device 11 through the pipeline 20, the water distributor 3 and the pipeline 20 to the terminal device 4 at the same time as building the conveying line.

[0067] In this embodiment, the communication between the water distributor 3 and the conveying group 2 also has the aforementioned advantages, which will not be repeated here. Example 3

[0068] Based on Embodiment 1 or Embodiment 2, in the conveying system provided in this embodiment, the conveying group 2 is further provided with a light-emitting component 7. The light-emitting component 7 is connected to a first processor 27, which is used to control the state of the light-emitting component 7, such as on / off state, color change, marquee effect, flashing state, etc. The light-emitting component 7 can be disposed on the first connector 22, the pipeline 20, or the second connector 20. The light-emitting component 7 includes, but is not limited to, indicator lights or electroluminescent lines (such as EL light lines or LED light strips, etc.) or screens, etc. For example, in this embodiment, the light-emitting component 7 includes electroluminescent lines, such as... Figure 15 and Figure 17As shown, the electroluminescent line is installed along the length of the conduit 20 to emit light along its length, thus providing better guidance and indication along the conduit 20. In actual use, the first processor 27 can control the state of the light-emitting component 7 in the conduit 20 via cascaded communication. This allows for more conspicuous display and the dissemination of specific information (such as evacuation or attack information) through changes in the state of the light-emitting component 7. For example, in an emergency, personnel at the back end can generate an evacuation signal via the terminal device 4 or a button in the remote command center. This evacuation signal is transmitted to the transport group 2 via cascaded communication. Upon receiving the evacuation signal, the first processor 27 of the transport group 2 changes the state of the light-emitting component 7 to a pre-defined state, such as flashing or a running light effect. Upon seeing the change in the state of the light-emitting component 7, personnel on site can immediately evacuate along the transport group 2, achieving the purpose of sending signals to personnel on site using light signals. The cascaded communication method not only makes the signal more stable but also improves evacuation efficiency, especially in situations where walkie-talkie communication is unreliable.

[0069] Similarly, in implementation, output group 1 may also include operating component 13, such as... Figure 16 and Figure 17 As shown, the operating component 13 is connected to the second processor 12. The operating component 13 can preferably be located at the end output device 11. The operating component 13 is mainly used to generate control signals (or adjustment signals) upon user triggering and feed them back to the second processor 12. The second processor 12 can transmit the control signals step by step through cascading communication to directly transmit information to the backend or directly control the backend devices. In implementation, the operating component 13 can be a button, knob, or touch screen, etc., for easier user operation. For example, in the event of an emergency at the front end, when the firefighters at the end output device 11 first discover the emergency, they can trigger the operation component 13 to send a warning, attack, or retreat signal to the first processor 27 of each conveyor group 2. After receiving the signal, the first processor 27 changes the state of the light-emitting component 7 to a pre-determined state, such as a running light or flashing light. When other personnel on site see the change in the state of the light-emitting component 7, they can immediately receive a warning or receive assistance in attacking or retreating along the conveyor group 2. This achieves the purpose of sending signals to personnel on site using light signals. The cascaded communication method not only makes the signal more stable but also improves the response speed. The effect is particularly significant when walkie-talkie communication is not smooth on site.

[0070] In a further embodiment, output group 1 also includes a pressure sensor 14 for detecting the outlet water pressure, the pressure sensor 14 being connected to the second processor 12, such as... Figure 16 andFigure 17 As shown, the first processor 27 of the terminal output device 11 can obtain the actual water pressure of the terminal output device 11 from the pressure sensor 14, and can transmit this water pressure to the terminal device 4 or the remote command center step by step through cascading communication, which is more conducive to realizing remote monitoring and intelligent decision-making. In implementation, the pressure sensor 14 can be preferentially set on the terminal output device 11.

[0071] Furthermore, in a further embodiment, output group 1 is also equipped with a repeater connected to the first processor 27 to further enhance communication in the central area of ​​the fire scene. For example, communication devices (such as walkie-talkies) of personnel near the end output unit 11 can be connected to the repeater and achieve more stable and interference-resistant communication with personnel at the back end via cascaded communication. Similarly, conveying groups (such as connectors, first connector 22 and / or second connector 24) are also equipped with repeaters connected to the first processor 27 in the conveying group to further enhance communication near the conveying group. For example, communication devices (such as walkie-talkies) of personnel near the conveying group can be connected to the repeater and achieve more stable and interference-resistant communication with personnel at the front end or back end via cascaded communication. In this case, the entire conveying system also enhances communication between personnel on site and effectively reduces communication interference, achieving more stable communication.

[0072] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
