Description

Technical Field

[0001] The present invention relates to the technical field of self-organizing networks, and in particular to a wireless signal repeater and an additional ejection mechanism for temporary emergency response. Background Art

[0002] The statements in this section only provide background information related to the present disclosure, and these statements may constitute prior art. In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art.

[0003] Due to poor base station coverage or base station damage, in environments with poor or no signals, such as military battlefields and urban security, as well as emergency rescue, various tunnel and bridge construction and inspection, it is difficult for the rear command center to overcome the terrain network barriers and continue to maintain contact with the front work department. Therefore, the use of multiple signal relay devices to form a local area network for data transmission is more suitable for such complex environments. At present, most of them use multiple wired signal repeaters to form a network and lay one way to ensure the reliability of data transmission.

[0004] However, due to the difficulty of wiring, especially in the battlefield and emergency rescue environment mentioned above, the terrain is complex, which further exacerbates the difficulty of self-organizing networks. Therefore, some technologies are now beginning to use wireless devices to replace the original wired transmission. For example, the patent application number 202311194650.X is named "A portable network signal rapid deployment device and method in a cable tunnel", which is a portable network signal rapid deployment device in a cable tunnel. The device includes a box, a router, a power module and a trolley. The router is a router that supports WIFI-AP. The box is detachably arranged on the trolley. The box is hinged with a cover body, and a storage chamber is formed in the box. The router and the power module are arranged in the chamber, and the box is provided with an external indicator light unit, a control button unit and an external interface unit. The device places the router and the power supply in the box to form a mobile communication network, and realizes the rapid movement of the box through the trolley, so as to achieve network coverage in places where the network is not smooth. It is easy to operate, and can also be used in coordination between multiple boxes, using the relay function of the router to adapt to different sizes of poor network areas.

[0005] In addition to quickly moving the network through a trolley, there is also networking through magnet adsorption. For example, the patent application number 202211435213.8 is named "A portable marine wireless self-organizing network device", which is installed on the bulkhead inside and outside the ship's cabin through magnet adsorption to quickly build a communication network.

[0006] Although the above method can meet the needs of wireless ad hoc networking to a certain extent, it completely ignores the serious limitations of the actual complex environment on wireless networking, and is not suitable for the special complex environment referred to in this application. The application is used in environments such as military battlefields, urban security, emergency rescue, etc., and the biggest challenge to wireless ad hoc networking is danger. Whether it is the hail of bullets that may be encountered in military battlefields and urban security, or the collapse, gas and natural gas explosions that may be encountered at any time in environments such as emergency rescue, it is very dangerous to use personnel to manually install multiple signal relay devices in the corresponding positions. What's more, in many areas, the terrain is complex, either very narrow and difficult for people to pass, or there are many obstacles on the ground, making it difficult for people to move. The above reasons lead to that this type of complex environment is not suitable for manual self-organizing networking, and danger may occur before the network is successfully laid, and it is difficult to contact the rear, and then it cannot be rescued. Therefore, it is very necessary to enter the above-mentioned area in advance by small robots to arrange wireless ad hoc networks in the early stage. However, due to the complex terrain and many obstacles, the robot is unable to pull the box of the "portable network signal rapid deployment device in the cable tunnel" around the obstacles to the corresponding position for networking. It is also difficult to install the "portable ship wireless self-organizing network equipment" through magnetic adsorption on walls, tree trunks, glass and other irregular attachments that cannot be magnetically adsorbed, making the above solutions impossible to implement.

[0007] In addition, the location of installing the relay device for ad hoc networking is also very particular. Especially in the above environment, due to the complex terrain, especially the ground is prone to many obstacles, if it is installed at a lower position, it will have a greater impact on the transmission of the signal. In particular, if there are special flammable and explosive conditions in this type of environment, it is impossible to use a high-power wireless relay device. It is necessary to install a low-power relay device in a location with higher terrain and fewer obstacles to better ensure the reliability of data transmission.

[0008] In summary, in the above-mentioned complex environment, how to enable temporary emergency wireless signal repeaters to overcome terrain network barriers and successfully realize self-organizing networks, and to ensure the reliability of their signal transmission as much as possible, is the real issue that such equipment should pay attention to.

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings. The embodiments of the present invention are only used to illustrate the present invention rather than to limit the present invention. Without departing from the technical idea of ​​the present invention, various substitutions and changes can be made according to common technical knowledge and customary means in the field, which should all be included in the scope of the present invention.

[0036] In order to make the wireless signal repeater more adaptable to actual complex environments, so that the wireless repeater can be set at the corresponding position by a remote-controlled robot in the early stage to realize wireless ad hoc networking and ensure the reliability of signal transmission as much as possible, the applicant designed the following wireless signal repeater.

[0037] like Figure 1 As shown in or 2, a wireless signal repeater for temporary emergency use includes a main body 7 for storing a communication working part; the communication working part includes a communication module 5, a battery assembly 3 and an antenna 4; the communication module 5 can transmit signals through the antenna 4; the battery assembly 3 is used to power the communication module 5; it also includes a disposable adhesive portion; the adhesive portion includes a colloid fixing seat 2 and a colloid 1 arranged at the front end of the colloid fixing seat 2; the colloid fixing seat 2 is detachably connected to the front end of the main body 7; the rear end of the main body 7 is connected to a tail cover 6.

[0038] The present application can remotely control a robot carrying a wireless signal repeater and an additional ejection mechanism for temporary emergency to enter environments such as military battlefields, urban security, emergency rescue, etc. in advance. While detecting dangers, the emergency wireless signal repeater can be ejected through an additional ejection mechanism at a location with poor signal or a preset location. Due to the ejection pressure, the colloid 1 of its bonding part can be firmly bonded to the attachment 17. By placing a number of emergency wireless signal repeaters on the path of the robot, a temporary local area network is formed so that the information of the front working unit and the rear command center that enter later can overcome the terrain network barrier, realize two-way interconnection, and complete the phased work.

[0039] Of course, if it is not a dangerous area, the staff can also carry the device of the present application into the area and use the additional ejection mechanism to eject the repeater to a higher attachment. If the signal transmission requirement is not too high, the ejection mechanism ejection method can be omitted, and the ejection method can be omitted, and the repeater of the present application can be directly bonded to the attachment 17.

[0040] The communication module 5 and the battery assembly 3 in the communication working part are all prior art. The communication module 5 and the antenna 4 can transmit or receive signals to form a network with other repeaters, and the battery assembly can also ensure that the wireless signal repeater of the present application does not require an external power supply.

[0041] The main body 7 of the present application may be made of plastic, and the antenna 4 may be disposed inside the main body 7. However, since the side wall of the main body 7 may collide with the attachment 17, and the antenna 4 disposed inside the main body 7 may have a certain impact on the reception and transmission of signals, the transmitting end of the antenna 4 extends from the side wall of the main body 7. Accordingly, the main body 7 may be made of a stronger metal or a thicker material to reduce the impact of the collision on the main body 7 and the internal equipment.

[0042] Preferably, when the repeater of the present application is pressed into the additional ejection mechanism, the transmitting end of the antenna 4 extending out of the main body 7 faces upward or to both sides to avoid collision with the attachment 17 after ejection and damage.

[0043] If the transmitting end of the antenna 4 extends from the side wall of the main body 7, after the adhesive portion is bonded to the attachment 17, the rear end of the main body 7 will fall toward the attachment 17 due to gravity. Figure 5 As shown, the transmitting end of the antenna 4 is horizontal after bonding. In addition, the wireless signal repeater can be ejected to the attachment 17 at a higher position, thereby greatly reducing the probability that the signal transmitted or received by the present application is blocked by obstacles on the ground, and improving the reliability of signal transmission.

[0044] At the same time, due to the improvement in the reliability of signal transmission, the communication module 5 of the present application can adopt low-power equipment, further reducing the weight of the wireless signal repeater of the present application, making it more compact and portable, and lightweight. Whether it is a robot or a staff member, it is easy to carry several repeaters for self-organizing networking.

[0045] Since the rear end of the main body 7 will fall toward the attachment 17 due to gravity after the wireless signal repeater of the present application is bonded to the attachment 17, a buffer layer is provided on the outer wall of the main body 7 to reduce the impact of the collision on the communication working part in the main body 7. The buffer layer can also be provided on the inner wall of the main body 7.

[0046] The tail cover 6 is provided with a through hole connected to the power switch 13 and / or the indicator light 14 of the communication working part. Figure 7 As shown. Since the USB interface 12, the power switch 13 and the indicator light 14 of the communication working part are all protected by the tail cover 6, and a buffer layer is provided between the tail cover 6 and the communication module 6, when ejected by the additional ejection mechanism, the components in the communication working part can be well protected from being damaged due to the ejection. Of course, the strength of the ejection also needs to be set accordingly, so that the wireless signal repeater of the present application can be adhered to the attachment 17, and the internal structure will not be damaged due to excessive ejection strength.

[0047] The buffer layer may be made of buffer materials such as foam.

[0048] The colloid 1 at the front end of the present application also achieves buffering to a certain extent when colliding with the attachment 17, thereby protecting the communication working part at the rear end.

[0049] The main body 7 is cylindrical and matches the ejection tube, making the ejection operation smoother. The side wall of the main body 7 is provided with a side wall groove to match the launch button 8 of the additional ejection mechanism. The wireless signal repeater can be suppressed or ejected by matching the launch button 8 with the side wall groove. Of course, the adaptation of the main body 7 can also be achieved by other existing launch buttons 8.

[0050] In order to prevent dust or flowing sewage from affecting the structure of the wireless signal repeater, the main body 7 and the tail cover 6 are preferably fixedly connected. Figure 1 As shown, the tail cover 6 can be bonded to the rear end of the main body 7; or, the tail cover 6 can be detachably connected to the rear end of the main body 7 and sealed by a sealing ring. The above sealing method can prevent dust from entering the main body 7, thereby reducing the impact of the external complex environment on the repeater, so that it is more adaptable to such complex environments.

[0051] Since the adhesive part of the present application is disposable, the colloid fixing seat 2 can be connected to the front end of the main body 7 by a detachable method such as threaded connection or snap connection, so that after the work or task is completed, the main body 7 with the communication working part can be directly removed so that the communication working part can be recycled and reused. The battery in the battery assembly 3 can be a rechargeable battery, and the tail cover 6 is provided with a through slot connected to the USB interface 12 of the communication working part, such as Figure 7 As shown, after the main body 7 with the communication working part is recycled, it can be charged and used again through the USB interface.

[0052] The front end of the main body 7 and the colloid fixing seat 2 can be connected by thread. Figure 2 As shown, the main body 7 is provided with a screw 16, and the colloid fixing seat 2 is provided with a threaded seat 15 adapted thereto. When the task is completed, under the guidance of the indicator light 14, the staff only needs to rotate the main body 7 to complete the recovery of the repeater. If the wireless signal repeater is bonded to a higher place and cannot be directly touched by human hands, the adapting protrusion at the top of the long rod can be firstly inserted into the through groove connecting the tail cover 6 and the USB interface 12, or simultaneously inserted into the through hole connecting the tail cover 6 and the power switch 13 and the indicator light 14, and then the main body 7 is driven to rotate by the rotation of the long rod, so that the main body 7 can be easily separated from the colloid fixing seat 2, which is convenient for the recovery of the communication working part.

[0053] Preferably, the colloid 1 is a pressure-sensitive adhesive, which can have a wide bonding range and can be attached to any object with strong bonding viscosity, even to regular or irregular attachments 17 such as cement walls, stone walls, tree trunks, plastics, rubber, glass, and cardboard.

[0054] When the adhesive part is not in use, the surface of the colloid 1 can be covered with a non-stick film. When in use, the non-stick film on the surface of the colloid 1 can be torn off.

[0055] like Figure 8 As shown, the colloid 1 is located in the middle of the colloid fixing seat 2, and its edge is located in the card slot of the colloid fixing seat 2. While ensuring that the wireless signal repeater is bonded to the attachment 17, the card slot of the colloid fixing seat 2 can also be used to fix the edge of the colloid 1, thereby increasing the contact area between the colloid 1 and the colloid fixing seat 2, so that the colloid fixing seat 2 will not be separated from the colloid 1 during ejection and collision.

[0056] An additional ejection mechanism is used to eject the wireless signal repeater used for temporary emergency.

[0057] Various types of additional ejection mechanisms can be used to perform ejection operations. Figure 3As shown in or 4, the additional ejection mechanism includes an ejection tube 10 and a launch button 8; the ejection tube 10 is adapted to the main body 7, and an ejection spring 9 is provided in its closed end, and the open end is used to place the wireless signal repeater for temporary emergency; the ejection tube 10 is provided with a groove adapted to the transmitting end of the antenna 4 passing through the side wall of the main body 7, so as to avoid the influence of the antenna transmitting end extending out of the side wall of the main body 7 during pressing and ejection, and also to avoid damage to the antenna 4.

[0058] The launch button 8 is mainly used to fix the wireless signal repeater so that it remains in the ejection state in the ejection tube 10. When ejection is required, the launch button 8 is controlled to no longer fix the repeater, so that it can be ejected by the ejection spring 9. The ejection operation is simple. It only needs to press the repeater into the ejection tube 10 before the robot enters, and press the launch button 8 into the side wall groove of the side wall of the main body 7 to fix the repeater; when ejection is required, release the launch button 8, and the compression spring 11 pushes the launch button 8 out, so that the repeater is ejected by the ejection spring 9.

[0059] The existing multiple ejection methods are all suitable for the ejection of the wireless signal repeater for temporary emergency use in this application. The additional ejection mechanism has a simple structure and can be set on multiple parts of the robot such as the shoulder and arm, and an angle adjuster can be set on the corresponding part to adjust the ejection angle of the additional ejection mechanism to better control the attachment position of the repeater.

[0060] The groove of the ejection tube 10 is used for the movement of the transmitting end of the antenna 4 extending out of the main body 7 so that it is not affected during ejection. The groove can be on the inner wall of the gun barrel, or the groove of the ejection tube 10 adapted to the transmitting end of the antenna 4 is a through groove, and the transmitting end of the antenna 4 extends out of the side wall of the ejection tube 10 through the through groove. Since the robot also needs wireless remote control, the antenna 4 extending out of the ejection tube 10 can also provide a better signal for the robot, so that it can be remotely controlled well when operating in a complex environment. At the same time, this setting can also enable the robot operator to promptly find the location with poor signal, so that the wireless signal repeater can be ejected well here, which is convenient for networking to adapt to the actual complex environment.

[0061] Of course, the staff can also use the above design to maintain a certain communication contact with the rear command department, so that they can get timely support from the rear in case of emergencies.

[0062] The wireless signal repeater used for temporary emergency in the present application is small and portable, lightweight, and can be attached to any object by ejection. A temporary local area network can be pre-established with multiple repeaters. It can be well used in local military battlefields with weak or no communication signals, urban security, emergency rescue, various road, tunnel and bridge construction and inspection scenarios, etc., so that the front work unit and the rear command center can overcome the terrain network barriers and realize the interconnection of information.

[0063] The fixed connection not specifically mentioned above may be a connection method such as riveting, welding, bolt connection, etc., and the movable connection may be a connection method such as hinged connection.
