Description

Technical Field

[0001] The present invention relates to a shielding device, and particularly to a storage and transportation shielding device for wireless signal forwarding. Background Art

[0002] When the equipment storage and transportation box is in a sealed state, it is an electromagnetic shielding body. Wireless signals outside the box cannot penetrate the outer wall of the storage and transportation box, and the equipment inside the box cannot receive wireless signals. To enable the equipment inside the storage and transportation box to receive signals, there are currently two receiving methods. The first is to use wired signal transmission. When using wired signal transmission, it is necessary to set up cables and electrical connectors for wired transmission between the equipment and the storage and transportation box. When the equipment is removed from the storage and transportation box, a separation mechanism is required to achieve the separation of electrical connection, which increases the complexity of the interface design of the storage and transportation box and the equipment.

[0003] When receiving wireless signals by directly opening the box lid, there are high requirements for the positions, distances, and signal intensities of the transceiver antennas of the equipment inside the box and the control system outside the box. Moreover, when the storage and transportation box and the equipment are loaded with a small clearance fit, even if the box lid of the storage and transportation box is opened, the wireless transmission signal will have a large attenuation during transmission in the small clearance space and is difficult to be reliably received by the receiving antenna of the equipment.

[0004] Therefore, how to forward the wireless signals outside the storage and transportation box to the equipment inside the box, improve the reliability of signal transmission, and reduce the complexity of the electrical system is a problem to be solved. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a wireless signal forwarding storage and transportation shielding device with a simple structure, high transmission efficiency, convenient and reliable signal transmission.

[0006] In one embodiment, a wireless signal forwarding storage and transportation shielding device of the present invention includes a storage and transportation part, a signal transmission part, and a signal receiving part for shielding external interference signals. The storage and transportation part includes a storage and transportation box, and a box door is provided on the storage and transportation box; the signal transmission part includes a signal receiver, a transmission cable, and a forwarding antenna. The signal receiver is provided on the outer wall of the storage and transportation box, and the forwarding antenna and the transmission cable are both provided on the inner wall of the storage and transportation box. The forwarding antenna is used for forwarding signals, and the transmission cable is used for connecting the signal receiver and the forwarding antenna and realizing signal transmission; the signal receiving part includes precision equipment provided inside the storage and transportation box, and the precision equipment is provided with a receiving antenna for receiving the signals forwarded by the forwarding antenna.

[0007] A wireless signal forwarding storage and transportation shielding device of the present invention, wherein the signal transmission part further includes an antenna mounting seat. The antenna mounting seat is provided with a hole facing the inside of the storage and transportation box. The antenna mounting seat is embedded in the storage and transportation box, and the forwarding antenna is arranged in the hole and connected to the transmission cable.

[0008] A wireless signal forwarding, storage and transportation shielding device of the present invention, wherein at least one cable branch is led out from the transmission cable; the forwarding antennas correspond to the cable branches one by one; the holes correspond to the forwarding antennas one by one; each cable branch is respectively connected to its corresponding forwarding antenna, and each forwarding antenna is respectively arranged in its corresponding hole.

[0009] A wireless signal forwarding, storage and transportation shielding device of the present invention, wherein the receiving antennas correspond to the forwarding antennas one by one.

[0010] A wireless signal forwarding, storage and transportation shielding device of the present invention, wherein the transmission cables are also embedded on the storage and transportation box.

[0011] A wireless signal forwarding, storage and transportation shielding device of the present invention, wherein a cable shield is sleeved on the transmission cable, and the cable shield is embedded on the top wall of the storage and transportation box.

[0012] A wireless signal forwarding, storage and transportation shielding device of the present invention, wherein a conductive sealing ring for shielding external interference signals is arranged between the box door and the storage and transportation box.

[0013] In another embodiment, a method for using a wireless signal forwarding, storage and transportation shielding device of the present invention includes the following steps:

[0014] (1) In an environment with external electromagnetic interference, use the shielding function of the storage and transportation box to reduce interference to precision equipment, so that the signal receiver arranged on the outer wall of the storage and transportation box receives wireless signals sent from a specific control device outside the storage and transportation box;

[0015] (2) The signal receiver transmits the received various wireless signals to the corresponding forwarding antennas respectively through the cable branches of the transmission cable arranged on the inner wall of the storage and transportation box;

[0016] (3) Each forwarding antenna re-forwards the wireless signal into the storage and transportation box in the form of radio waves;

[0017] (4) A plurality of receiving antennas arranged on the precision equipment in the storage and transportation box respectively receive the wireless signals re-forwarded by the corresponding forwarding antennas to control the precision equipment. At the same time, the receiving antennas send feedback signals, the feedback signals are received by the corresponding forwarding antennas, then reversely transmitted to the signal receiver through the cable branches of the transmission cable, and finally the signal receiver sends the feedback signals to a specific control device outside the storage and transportation box to complete the information interaction inside and outside the storage and transportation box.

[0018] The difference between the present invention and the prior art lies in that the storage and transportation box of the present invention has a shielding function, and the wireless signal outside the storage and transportation box is transmitted through the signal receiver, transmission cable and forwarding antenna embedded in the top of the storage and transportation box. Then, through the secondary forwarding of the wireless signal by the forwarding antenna, the wireless signal is transmitted into the storage and transportation box. Finally, the precision equipment in the storage and transportation box receives the wireless signal through the receiving antenna and sends out the feedback signal through the receiving antenna. The feedback signal is received by the corresponding forwarding antenna, then reversely transmitted to the signal receiver through each cable branch of the transmission cable, and finally the signal receiver sends the feedback signal to the control equipment outside the storage and transportation box, completing the two-way transmission of signals and information interaction inside and outside the storage and transportation box.

[0019] The wireless signal forwarding storage and shielding device of the present invention has at least the following beneficial effects:

[0020] (1) There is no need to set up wired devices or open the box lid for signal transmission, which can not only reduce the complexity of the system, but also have high signal transmission reliability, and can avoid interference of other signals on the precision equipment in the storage and transportation box.

[0021] (2) The layout method of integrating the antenna mounting seat with the box body avoids additional occupation of the space inside the box, improves the space utilization rate of the storage and transportation box, enhances the firmness of the connection between the forwarding antenna and the storage and transportation box, reduces signal transmission interference caused by loosening, and improves the stability of wireless signal transmission.

[0022] (3) During the wireless signal transmission process, the storage and transportation box always maintains a shielding state, which can prevent external interference signals from affecting the signal receiver's signal reception and transmission, and ensure the effective transmission of two-way transmitted signals.

[0023] The present invention will be further described below with reference to the accompanying drawings. Description of the Drawings

Detailed Implementation Manner

[0030] As Figure 1 As shown, a wireless signal repeater storage and shielding device of the present invention includes a storage and transportation department 01, a signal transmission department 02, and a signal reception department 03 for shielding external interference signals. The storage and transportation department 01 includes a storage and transportation box 11; the signal transmission department 02 includes a signal receiver 21, a transmission cable 22, and a repeater antenna. The signal receiver 21 is arranged on the outer wall of the storage and transportation box 11, and the affiliated repeater antenna and transmission cable 22 are both arranged on the inner wall of the storage and transportation box 11. Among them, the repeater antenna is used to forward signals, and the transmission cable 22 is used to connect the signal receiver 21 and the repeater antenna and realize signal transmission; the signal reception department 03 includes precision equipment 31 arranged in the storage and transportation box 11, and the precision equipment 31 is provided with a receiving antenna 32 for receiving the signals forwarded by the repeater antenna.

[0031] To prevent the precision equipment 31 in the storage and transportation box 11 from being interfered by external signals, the storage and transportation box 11 is made of materials with shielding functions, such as steel and copper, so that the storage and transportation box 11 has shielding functions and certain sealing properties.

[0032] The shape of the storage and transportation box 11 is not particularly limited. Preferably, it is a cuboid shape, which not only has a certain stability but also is convenient for movement. At least one box door 12 is provided on the storage and transportation box 11. On the one hand, the precision equipment 31 is taken and placed through the box door 12; on the other hand, it is convenient for maintaining the inside of the storage and transportation box 11. A groove for installing the signal receiver 21 is provided on the upper surface of the top wall of the storage and transportation box 11, and the signal receiver 21 is firmly installed in the groove. When necessary, a rubber pad is sleeved on the signal receiver 21, and the rubber pad is sleeved on the outer periphery of the signal receiver 21. An installation hole is provided on the top wall of the storage and transportation box 11, and the signal receiver 21 with the rubber pad is inserted into the installation hole to ensure its firm installation and sealing performance.

[0033] The right end of the transmission cable 22 installed on the inner wall of the top wall of the storage and transportation box 11 is connected to the signal receiver 21, and the left end of the transmission cable 22 is connected to the forwarding antenna, thereby forming a wireless signal transmission channel. The wireless signal emitted by a specific control device outside the storage and transportation box 11 is transmitted through the transmission cable 22 to the forwarding antenna inside the storage and transportation box 11 via the signal receiver 21, and the wireless signal is retransmitted inside the storage and transportation box 11 through the forwarding antenna.

[0034] A signal receiving antenna 32 is installed on the precision device 31 inside the storage and transportation box 11. The signal receiving antenna 32 can search for and receive the wireless signal retransmitted by the forwarding antenna and feed it back to the precision device 31, thereby completing the transmission of the wireless signal from outside to inside the storage and transportation box 11 in a shielded state. There is no need to set up a wired device or open the box lid for signal transmission, which can not only reduce the complexity of the system, but also ensure high reliability of signal transmission and avoid interference of other signals to the precision device 31 inside the storage and transportation box 11.

[0035] As Figure 1 、 2 As shown, the signal transmission unit 02 further includes an antenna mounting base 24. The antenna mounting base 24 is provided with a hole 25 facing the inside of the storage and transportation box. The antenna mounting base 24 is embedded in the storage and transportation box 11, and the forwarding antenna is arranged in the hole 25 and connected to the transmission cable 22.

[0036] The antenna mounting base 24 is embedded in the top wall of the storage and transportation box 11 and integrated with the box body, and the seamless connection between the two ensures the airtightness of the storage and transportation box 11. The forwarding antenna is installed in the hole 25 to establish a stable signal connection with the precision device 31 inside the storage and transportation box 11. The hole 25 can serve as a signal transmission channel between the forwarding antenna and the precision device 04. The transmission cable 22 is connected to the forwarding antenna in the hole 25. On the one hand, due to the integrated layout of the antenna mounting base 24 and the box body, it avoids occupying extra space inside the box and improves the space utilization rate of the storage and transportation box 11; on the other hand, the tight combination of the antenna mounting base 24 and the box body and the stable connection with the transmission cable 22 enhance the firmness of the connection between the forwarding antenna and the storage and transportation box 11, reduce the signal transmission interference caused by loosening, and improve the stability of wireless signal transmission.

[0037] As Figure 2 、 3 As shown, the transmission cable 22 leads out at least one cable branch; the forwarding antenna corresponds to the cable branch one by one; the hole 25 corresponds to the forwarding antenna one by one; each cable branch is respectively connected to its corresponding forwarding antenna, and each forwarding antenna is respectively arranged in its corresponding hole 25. The receiving antenna 32 corresponds to the forwarding antenna one by one.

[0038] According to the actual situation and signal transmission requirements, the transmission cable 22 can lead out multiple cable branches to transmit different signals accordingly. In the present invention, three cable branches, the corresponding holes 25 and receiving antennas 32 are enumerated to elaborate on the wireless signal transmission process.

[0039] The right end of the transmission cable 22 is connected to the signal receiver 21, and the left end leads out the first cable branch 221, the second cable branch 222 and the third cable branch 223. Different signals received by the signal receiver 21 are respectively transmitted through the three cable branches to improve the signal transmission efficiency. The forwarding antennas include a first forwarding antenna 26, a second forwarding antenna 27 and a third forwarding antenna 28; the holes 25 include a first hole 251, a second hole 252 and a third hole 253; the first forwarding antenna 26, the second forwarding antenna 27 and the third forwarding antenna 28 are respectively firmly installed in the first hole 251, the second hole 252 and the third hole 253. The first cable branch 221, the second cable branch 222 and the third cable branch 223 are respectively connected to the first forwarding antenna 26, the second forwarding antenna 27 and the third forwarding antenna 28, and transmit the signals on their respective cable branches to the corresponding forwarding antennas respectively. The signal receiver 21 is a broadband signal receiver that can receive signals of various frequency bands, avoiding signal loss and ensuring signal integrity.

[0040] The antenna mounting base 24 is embedded in the top of the storage and transportation box 11. The hole 25 communicates with the inside of the storage and transportation box 11. When the receiving antenna 32 is installed in the hole 25, the receiving antenna 32 completely blocks or covers the hole 25, and the two are seamlessly matched to ensure the airtightness and shielding performance of the storage and transportation box 11. Each forwarding antenna re-forwards the received wireless signal into the storage and transportation box 11 in the form of radio waves. Due to the shielding function of the storage and transportation box 11, the re-forwarded wireless signal is not interfered by the outside world.

[0041] The number of receiving antennas 32 on the precision device 31 is the same as the number of forwarding antennas (i.e., one-to-one correspondence). The receiving antenna 32 is an antenna that can receive specific signals. Here, the first receiving antenna 321, the second receiving antenna 322 and the third receiving antenna 323 are taken as examples to illustrate the signal receiving process. The position of the receiving antenna 32 is not particularly limited. Preferably, it is on the upper surface of the precision device 31 to facilitate more efficient signal reception. After the three forwarding antennas re-forward the signal into the storage and transportation box 11, the precision device 31 filters the signals re-forwarded by the corresponding forwarding antennas through the receiving antenna 32, and then transmits the received specific signals to the precision device 31. The three receiving antennas 32 on the precision device 31 respectively receive the corresponding signals. For example, the first receiving antenna 321 receives the wireless signal re-forwarded by the first forwarding antenna 26, and the second receiving antenna 322 and the third receiving antenna 323 respectively receive the wireless signals re-forwarded by the second forwarding antenna 27 and the third forwarding antenna 28, so as to control the precision device 31.

[0042] A wireless signal forwarding, storage and shielding device of the present invention can perform two-way transmission of wireless signals. After the precision device 31 receives the wireless signal sent by the control device, it emits corresponding feedback signals through three receiving antennas 32 (i.e., the first receiving antenna 321, the second receiving antenna 322, and the third receiving antenna 323). The corresponding three signal forwarding antennas (i.e., the first forwarding antenna 26, the second forwarding antenna 27, and the third forwarding antenna 28) receive the corresponding feedback signals, and then transmit the signals to the signal receiver 21 through the cable branches connected thereto (i.e., the first cable branch 221, the second cable branch 222, and the third cable branch 223). The signal receiver 21 then transmits the feedback signal to the control device outside the storage box 11, achieving the purpose of information interaction inside and outside the storage box 11.

[0043] During the wireless signal transmission process, the storage box 11 always maintains a shielding state. On the one hand, it can prevent external interference signals from affecting the signal transceiver of the signal receiver 21 and ensure the effective transmission of signals; on the other hand, it ensures that the precision device 31 with a certain degree of confidentiality inside the storage box 11 is not affected by external signals.

[0044] As Figure 1 、 4 shown, a cable shield 23 is sleeved on the transmission cable 22, and the cable shield 23 is embedded in the top wall of the storage box 11.

[0045] A cable groove is provided along the length direction in the center of the top wall of the storage box 11. The cable shield 23, like the antenna mounting base 24, is embedded in the cable groove on the top wall of the storage box 11. The transmission cable 22 is inside the cable shield 23. Both the cable shield 23 and the antenna mounting base 24 are box-shaped, which is convenient for seamless cooperation with the storage box 11. The left end of the cable shield 23 is closely docked with the right end of the antenna mounting base 24 to ensure that there is no gap on the top wall of the storage box 11, thereby ensuring the airtightness of the storage box 11. A through hole is provided at the right end of the antenna mounting base 24, and the transmission cable 22 passes through the through hole and is connected to the forwarding antenna, reducing external interference and losses during signal transmission. An installation hole is provided on the upper surface of the right side of the cable shield 23, and the signal receiver 21 is fixed in the installation hole and connected to the transmission cable 22 to ensure stable transmission of wireless signals. Since the signal receiver 21 is fixed on the upper surface of the cable shield 23, it can be regarded as the signal receiver 21 being provided on the outer wall of the storage box 11.

[0046] The top wall of the antenna mounting base 24 is provided with a protective cover 29 that can open and close the antenna mounting base. On the one hand, the protective cover 29 can shield external signals, ensuring that the repeater antenna and cable branches in the antenna mounting base 24 are not interfered by external signals. On the other hand, the protective cover 29 covers the top of the antenna mounting base 24, making the cable branches and repeater antenna not exposed, reducing damage caused by factors such as dust and moisture, and extending its service life.

[0047] Since the three holes 25 all face the inside of the storage and transportation box 11, and the three repeater antennas are respectively arranged on the three holes 25, it can be considered that the three repeater antennas are all arranged on the inner wall of the storage and transportation box 11.

[0048] The transmission cable 22 is as Figure 2 、 3 shown. A conductive sealing ring 13 for shielding external interference signals is provided between the box door 12 and the storage and transportation box 11.

[0049] The conductive sealing ring 13 can be installed on the storage and transportation box 11 or on the box door 12. When the box door 12 is closed, the conductive sealing ring 13 is located at the gap between the storage and transportation box 11 and the box door 12. When an external signal tries to enter the storage and transportation box 11, an induced current will be generated in the conductive sealing ring 13. The induced current generates an electromagnetic field opposite to the external signal electromagnetic wave, which plays a role in canceling and reflecting the external signal electromagnetic wave. At the same time, the conductive sealing ring 13 will absorb and dissipate the energy of the external limited signal electromagnetic wave, converting it into heat energy and dissipating it, so as to achieve the function of sealing and shielding, effectively improving the shielding performance of the storage and transportation box 11 and ensuring that external signals will not interfere with the precision equipment 31 in the storage and transportation box 11.

[0050] The material of the conductive sealing ring 13 can be flexibly selected according to the actual use scenario and specific performance requirements, such as commonly used materials like conductive rubber, metal wire mesh, conductive fiber fabric, and metal rubber.

[0051] The usage method of a wireless signal repeater storage and transportation shielding device of the present invention is as follows:

[0052] (1) Using the shielding function to reduce interference: In an environment with external electromagnetic interference, use the shielding function of the storage and transportation box 11 to reduce interference to the precision equipment 31, so that the signal receiver 21 arranged on the outer wall of the storage and transportation box 11 receives wireless signals sent from a specific control device outside the storage and transportation box 11, ensuring the accuracy of signal reception. The signal receiver 21 is a broadband signal receiver that can receive signals of various frequency bands.

[0053] (2) Signal transmission: The signal receiver 21 transmits the received various wireless signals to the corresponding repeater antennas respectively through the cable branches of the transmission cable 22 arranged on the inner wall of the storage and transportation box 11, ensuring that the signal can be stably transmitted from outside the box to inside the box.

[0054] (3) Signal retransmission: Each retransmission antenna retransmits the wireless signal in the form of radio waves into the storage and transportation box 11. During this process, the storage and transportation box 11 continuously plays a shielding role to block external interference and ensure the stability of signal retransmission.

[0055] (4) Signal reception and device interaction: A plurality of receiving antennas 32 provided on the precision device 31 in the storage and transportation box 11 respectively receive the wireless signals retransmitted by the corresponding retransmission antennas, so as to realize the control or data interaction of the precision device 31. Among them, the receiving antenna 32 is an antenna that can receive specific signals. The precision device 31 filters the signals retransmitted by the corresponding retransmission antennas through the receiving antenna 32 according to requirements, and transmits the specific signals to the precision device 31 after filtering. At the same time, when the precision device 31 completes the corresponding operation, the receiving antenna 32 can send a feedback signal. The feedback signal is received by the corresponding retransmission antenna, and then reversely transmitted to the signal receiver 21 through each cable branch of the transmission cable 22. Finally, the signal receiver 21 sends the feedback signal to a specific control device outside the storage and transportation box 11, so as to realize the bidirectional transmission of signals and the information interaction inside and outside the storage and transportation box 11.
