Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a radiation system in the related art. As can be seen with reference to fig. 1, the radiation system may comprise: the device comprises an upper computer 01, a frame 02, an image acquisition component 03 and a treatment head 04 which are arranged on the frame 02, a power supply cable 05 and a signal cable 06. Among them, the rack 02 may include a stationary rack 021 and a rotating rack 022. The fixed rack 021 can be fixedly arranged on the ground, and the rotating rack 022 is rotationally connected with the fixed rack 021. The image acquisition component 03 and the treatment head 04 can be arranged on the rotating rack 022, and the rotating rack 022 can drive the image acquisition component 03 and the treatment head 04 to rotate around the rotating shaft of the rotating rack 022.

The upper computer 01 may be a control device in the radiation system. The upper computer 01 can be used for controlling all components in the radiation system. Referring to fig. 1, the upper computer 01 and the image capturing assembly 03, and the upper computer 01 and the treatment head 04 may be connected by a signal cable 06, and the upper computer 01 may transmit a control signal to the image capturing assembly 03 and the treatment head by the signal cable 06. Correspondingly, the image acquisition component 03 can also send image information to the upper computer 01 through the signal cable 06.

Referring to fig. 1, the upper computer 01, the image capturing assembly 03, and the treatment head 04 are further connected to a power supply via a power supply cable 05. The power supply can provide power signals for the upper computer 01, the image acquisition assembly 03 and the treatment head 04, so that the upper computer 01, the image acquisition assembly 03 and the treatment head 04 can be in a working state.

Because when rotatory frame 022 is rotatory, the subassembly 03 and the treatment head 04 of image acquisition of setting on this rotatory frame 022 can rotate jointly, and this subassembly 03 and the treatment head 04 of image acquisition all need be connected with the power through power supply cable 05 to be connected with host computer 01 through signal cable 06, but this power supply cable 05 and signal cable 06's length are limited, consequently this rotatory frame 022 only can be in the angle range rotation that power supply cable 05 and signal cable 06's length allowed, the flexibility is relatively poor.

The problem of relatively poor flexibility that leads to because the frame can only rotate in certain angular dimension in the prior art is solved in order to solve. The embodiment of the invention provides a signal transmission device of radiation equipment. Referring to fig. 2, the signal transmission apparatus 00 may include: the first wireless transmission component 001. The first wireless transmission component 001 may include: a first antenna 0011 and a second antenna 0012.

The first antenna 0011 may be a loop antenna, and the first antenna 0011 may be disposed on the chassis 101 in the radiation device 10, the first antenna 0011 being capable of rotating in synchronization with the chassis 101.

The second antenna 0012 can be provided independently of the housing 101, and the second antenna 0012 can be wirelessly connected to the first antenna 0011.

In the embodiment of the present invention, the loop antenna 0011 may be an antenna in a loop shape, and the second antenna 0012 may be an antenna capable of communicating with the loop antenna 0011, for example, the second antenna 0012 may be a cylindrical antenna, and the second antenna 0012 may also be referred to as a connection antenna.

When the gantry 101 rotates, the first antenna 0011 provided on the gantry 101 may rotate in synchronization with the gantry 101, and the second antenna 0012 provided independently of the gantry 101 remains stationary. That is, when the housing 101 rotates, the first antenna 0011 provided on the housing 101 and the second antenna 0012 provided independently of the housing 101 rotate relatively. Because the second antenna 0012 is wirelessly connected to the first antenna 0011, that is, the second antenna 0012 and the first antenna 0011 communicate with each other in a wireless transmission manner, the rotation angle of the rack 101 is not affected, and the rack 101 can rotate within any angle range, so that the flexibility is good.

In summary, an embodiment of the present invention provides a signal transmission apparatus for a radiation device, where the signal transmission apparatus may include: a first wireless transmission component, the first wireless transmission component comprising: a first antenna and a second antenna. When the rack rotates, the first antenna and the second antenna can rotate relatively, but the first antenna and the second antenna are in wireless connection, so that the rotating angle of the rack cannot be influenced, the rack can rotate in any angle range, and the flexibility is good.

As can also be seen with reference to fig. 2, the first wireless transmission component 001 may further include: a first wireless bridge 0013 and a second wireless bridge 0014.

The first antenna 0011 can be connected to the first wireless bridge 0013, the first wireless bridge 0013 can be used to connect to the lower computer 20, and the first wireless bridge 0013 and the lower computer 20 can be both disposed on the rack 101. The second antenna 0012 can be coupled to the second wireless bridge 0014, the second wireless bridge 0014 can be configured to couple to the host computer 30, and the second wireless bridge 0014 and the host computer 30 can both be disposed independently of the rack 101.

In the embodiment of the present invention, the wireless network bridge may be a device capable of implementing a bridge for setting up communication between two or more networks by using a wireless transmission method, and the wireless network bridge may also be referred to as a wireless router. The lower computer 20 may be a device capable of directly controlling the radiation device 10 and acquiring an operating state of the radiation device 10, for example, the lower computer 20 may be a Programmable Logic Controller (PLC) or integrated circuit chips (microcontrollers). The upper computer 30 may be a human-computer interaction device capable of directly issuing a manipulation command. For example, the upper computer 30 may be a computer. Generally, the upper computer obtains a manipulation command and then sends the manipulation command to the lower computer, and the lower computer controls the operation of the radiation device 10 according to the manipulation command.

Fig. 3 is a diagram of a first wireless transmission component according to an embodiment of the invention.

Referring to fig. 2 and 3, the first antenna 0011 and the first wireless bridge 0013, the first wireless bridge 0013 and the lower computer 20 may be connected by cables, and the second antenna 0012 and the second wireless bridge 0014, and the second wireless bridge 0014 and the upper computer 30 may be connected by cables.

When the gantry 101 rotates, the first antenna 0011, the first wireless bridge 0013, and the lower computer 20 provided on the gantry 101 may rotate synchronously. When the gantry 101 remains stationary, the first antenna 0011, the first wireless bridge 0013, and the lower computer 20 provided on the gantry 101 also remain stationary. That is, the first antenna 0011, the first wireless bridge 0013 and the lower computer 20 are stationary with respect to each other regardless of the rotation of the rack 101. The cables between the first antenna 0011 and the first wireless bridge 0013, and between the first wireless bridge 0013 and the lower computer 20 do not affect the rotation of the rack 101.

The second antenna 0012, the second wireless bridge 0014 and the upper computer 30 are all independent of the rack 101, so that the second antenna 0012, the second wireless bridge 0014 and the upper computer 30 are relatively static no matter whether the rack 101 rotates or not. Cables between the second antenna 0012 and the second wireless bridge 0014 and between the second wireless bridge 0014 and the upper computer 30 do not affect the rotation of the rack 101.

According to the above analysis, since the first antenna 0011 and the first wireless bridge 0013, the first wireless bridge 0013 and the lower computer 20, the second antenna 0012 and the second wireless bridge 0014, and the second wireless bridge 0014 and the upper computer 30 which are connected by cables are all relatively stationary, even if the first antenna 0011 and the second antenna 0012 rotate relatively, the rotation angle of the rack 101 is not affected, and the rack 101 can rotate in any angle range, which is better in flexibility.

Fig. 4 is a top view of the radiating device and signal transmission means shown in fig. 2. As can be seen in connection with fig. 2 and 4, the gantry 101 may be a ring gantry. The first antenna 0011 may be disposed on an end surface of one end of the ring chassis 101. The first wireless bridge 0013 and the lower computer 20 may be both disposed on a sidewall of the ring gantry 101.

Of course, the frame 101 may also be a C-shaped frame or a drum-shaped frame, and the shape of the frame 101 is not limited in the embodiment of the present invention.

Optionally, the first antenna 0011 may be an annular leaky-wave cable, so that reliability and stability of data transmission are ensured.

Fig. 5 is a schematic structural diagram of another radiation device and a signal transmission apparatus according to an embodiment of the present invention.

Fig. 6 is a top view of the radiating device and signal transmission means shown in fig. 5. Fig. 7 is a diagram of a second wireless transmission component according to an embodiment of the invention. With reference to fig. 5 to 7, the signal transmission apparatus 00 may further include: the second wireless transmission component 002. The second wireless transmission component 002 may include: a plurality of third antennas 0021 and at least one fourth antenna 0022. By way of example, two third antennas 0021 and one fourth antenna 0022 are shown in fig. 5 and 6.

Each of the third antennas 0021 may be disposed on the chassis 101 of the radiation device 10, and each of the third antennas 0021 may be rotatable in synchronization with the chassis 101.

Each fourth antenna 0022 may be disposed independently of the chassis 101, and the fourth antenna 0022 may be wirelessly connected to each third antenna 0021. Alternatively, the fourth antenna 0022 may be provided on a wall of the equipment room where the radiation device 10 is placed.

Wherein, the signal transmission bandwidth of the second wireless transmission component 002 can be larger than the signal transmission bandwidth of the first wireless transmission component 001. That is, the second wireless transmission component 002 can be used for transmitting signals with larger bandwidth, and the first wireless transmission component 001 can be used for transmitting signals with smaller bandwidth.

In an embodiment of the present invention, the third antenna 0021 may be an omni-directional antenna. For example, the third antenna 0021 can be cylindrical, i.e., a cylindrical antenna. The fourth antenna 0022 may be a semi-cylindrical antenna with a cylindrical surface proximate to the third antenna 0021 and a planar surface disposed away from the third antenna 0021. The fourth antenna 0022 may also be referred to as a base station antenna.

Referring to fig. 5 to 7, the second wireless transmission component 002 may further include: a third wireless bridge 0023 and a fourth wireless bridge 0024.

Each third antenna 0021 may be connected to the third wireless bridge 0023, which third wireless bridge 0023 may be used to connect to the image processing component 102 in the radiation device 10. The third wireless bridge 0023 and the image processing component 102 may both be disposed on the chassis 101.

Each fourth antenna 0022 may be connected to the fourth wireless bridge 0024, which fourth wireless bridge 0024 may be configured to connect to the host computer 30. The fourth wireless bridge 0024 and the host computer 30 may both be provided independently of the rack 101.

Referring to fig. 6, the third antenna 0021, the third wireless bridge 0023, and the image processing component 102 may all be disposed on a sidewall of the chassis 101. The fourth antenna 0022 and the fourth wireless bridge 0024 may both be disposed on a wall of the equipment room.

It should be noted that the second wireless transmission component 002 is respectively connected to the image processing component 102 and the upper computer 30, and can be used for transmitting the image information of the image processing component 102 to the upper computer 30.

In the embodiment of the present invention, cables may be used for connecting between the third antenna 0021 and the third wireless bridge 0023, between the third wireless bridge 0023 and the image processing component 102, between the fourth antenna 0022 and the fourth wireless bridge 0024, and between the fourth wireless bridge 0024 and the upper computer 30.

When the rack 101 rotates, the third antenna 0021, the third wireless bridge 0023, and the image processing component 102 disposed on the rack 101 may rotate synchronously with the rack 101, and the third antenna 0021, the third wireless bridge 0023, and the image processing component 102 are relatively stationary between each other, so that the cable between the third antenna 0021 and the third wireless bridge 0023, and the cable between the third wireless bridge 0023 and the image processing component 102 do not affect the rotation of the rack 101.

This fourth antenna 0022, fourth wireless bridge 0024 to and host computer 30 all are independent of frame 101 setting, consequently no matter whether frame 101 is rotatory, fourth antenna, fourth wireless bridge 0024, and host computer 30 all relative still between two liang. Cables between the fourth antenna 0022 and the fourth wireless bridge 0024, and between the fourth wireless bridge 0024 and the upper computer 30, do not affect the rotation of the rack 101.

Moreover, since the third antenna 0021 and the fourth antenna 0022 are wirelessly connected, that is, the third antenna 0021 and the fourth antenna 0022 communicate with each other by wireless transmission, even if the rack 101 rotates, the third antenna 0021 and the fourth antenna 0022 rotate relatively to each other, the rotation of the rack 101 is not affected, and the rack 101 can rotate at any angle, so that the flexibility is good.

Optionally, the working frequency band of the third antenna 0021 and the working frequency band of the fourth antenna 0022 may both be a 5GHz (gigahertz) frequency band or a 2.4GHz frequency band, and there are more selectable frequency bands of the working frequency bands, so that the flexibility is better. The working frequency band of the third antenna 0021 and the working frequency band of the fourth antenna 0022 are not limited in the embodiments of the present invention.

Fig. 8 is a schematic structural diagram of another radiation device and a signal transmission apparatus according to an embodiment of the present invention. As can be seen with reference to fig. 8, the signal transmission apparatus 00 may further include: a cable transmission component 003. The wired transmission component 003 can be used to transmit power signals. Of course, the wired transmission component 003 can also be used to transmit data signals and control signals.

Referring to fig. 8, the wired transmission component 003 may include: slip rings 0031 and carbon brushes 0032. The slip ring 0031 may be provided on the frame 101. The carbon brush 0032 may be provided independently of the machine frame 101 and in contact with the slip ring 0031. The carbon brushes 0032 can be used to connect a first control module (not shown in fig. 8) disposed independently of the machine frame 101, and the slip rings 0031 can be used to connect a second control module (not shown in fig. 8) disposed on the machine frame 101.

The first control component may be a control cabinet that is provided separately from the rack 101 and is integrated with various components, and the second control component may be a control cabinet provided on the rack 101. The first control assembly can be coupled to a second control assembly via slip rings 0031 and carbon brushes 0032 to provide power signals to the second control assembly. The second control component may also be connected to the lower computer 20 to provide a power signal to the lower computer 20. And, data signal or control signal can also be transmitted between this first control assembly and the second control assembly.

Since the slip ring 0031 and the carbon brush 0032 can be kept in contact regardless of the rotation of the housing 101, signal transmission between the first control assembly and the second control assembly can be achieved by the slip ring 0031 and the carbon brush 0032. Moreover, the slip ring 0031 and the carbon brush 0032 do not need to be connected by a cable, so that the rotation angle of the frame 101 is not affected, and the frame 101 can rotate in any angle range.

It should be noted that, because the slip ring 0031 and the carbon brush 0032 are in direct contact, the real-time performance of signal transmission between the first control assembly and the second control assembly is better, so that the slip ring 0031 and the carbon brush 0032 can be used to transmit signals with higher real-time requirements, for example, power signals. Or may transmit at least one of a control signal and a data signal which have a high requirement for real-time. Wherein the control signal may include: a gating signal and an interlock signal.

When the slip ring 0031 and the carbon brush 0032 are used for transmitting power signals, power supply cables are not needed to supply power to all components in the radiation equipment 10, the influence of the power supply cables on the rotation of the rack 101 is avoided, and the flexibility of the rotation of the rack 101 is ensured.

In an embodiment of the present invention, the slip ring 0031 may include a plurality of annular conductive tracks, and the plurality of conductive tracks may be arranged on an end surface of the other end of the rack 101 in a radial direction of the rack 101. That is, the slip ring 0031 and the first antenna 0011 may be disposed on both end surfaces of the chassis 101 to be opposed to each other.

Alternatively, the slip ring 0031 may include: a first sub-slip ring 0031a and a second sub-slip ring 0031b, each of which may include a plurality of conductive tracks. The carbon brush 0032 may include: a first sub carbon brush 0032a and a second sub carbon brush 0032 b. The first sub slip ring 0031a may be in contact with a first sub carbon brush 0032a, and the second sub slip ring 0031b may be in contact with a second sub carbon brush 0032 b.

Here, the first sub slip ring 0031a and the first sub carbon brush 0032a may be used to transmit a power signal, and the second sub slip ring 0031b and the second sub carbon brush 0032b may be used to transmit a control signal and a data signal. Of course, it is also possible to transmit a control signal and a data signal using the first sub slip ring 0031a and the first sub carbon brush 0032a, and transmit a power signal using the second sub slip ring 0031b and the second sub carbon brush 0032 b. The embodiment of the present invention is not limited thereto.

By way of example, the slip ring 0031 may include 20 annular conductive tracks, wherein the first sub-slip ring 0031a may include 9 conductive tracks and the second sub-slip ring 0031b may include 11 conductive tracks. That is, 9 conductive tracks in the first sub slip ring 0031a may be used to transmit power signals with the first sub carbon brush 0032 a. Control signals and data signals are transmitted with the second sub carbon brush 0032b using 11 conductive tracks in the second sub slip ring 0031 b.

Referring to fig. 8, the wired transmission component 003 may further include: a carbon brush holder 0033. The carbon brush holder 0033 may be fixedly connected to the carbon brush 0032, and the carbon brush holder 0033 may be used to support the carbon brush 0032. Through setting up this carbon brush support 0033, can guarantee when frame 101 is rotatory, this carbon brush 0032 can not remove, guarantees the reliability of sliding ring 0031 and carbon brush 0032 transmission signal.

For example, two carbon brush holders 0033 are shown in fig. 8, and the two carbon brush holders 0033 have a certain distance therebetween, so that a first sub-carbon brush 0032a and a second sub-carbon brush 0032b, which are respectively connected to the two carbon brush holders 0033, have a distance therebetween, thereby facilitating daily cleaning and maintenance by a maintenance worker.

Fig. 9 is a schematic structural diagram of another radiation device and a signal transmission device according to an embodiment of the present invention. Referring to fig. 9, the signal transmission apparatus provided in the embodiment of the present invention may include a first wireless transmission component 001, a second wireless transmission component 002, and a wired transmission component 003 at the same time.

The first wireless transmission component 001 can be used for transmitting data signals with small data volume and small bandwidth occupation between the lower computer 20 and the upper computer 30. The second wireless transmission component 002 can be used to transmit image signals with large data volume and large bandwidth occupation. The slip rings 0031 and carbon brushes 0032 in the wired transmission assembly 003 can be used to transmit at least one of electrical signals, control signals, and data signals for which real-time requirements are high.

Fig. 10 is a schematic structural diagram of a radiation system according to an embodiment of the present invention. Referring to fig. 10, the radiation system may include: the radiation device 10 and the signal transmission apparatus 00 provided in the above embodiments. The signal transmission device may be the signal transmission device 00 shown in any one of fig. 2, fig. 4 to fig. 6, and fig. 8 to fig. 9.

As can be seen in conjunction with fig. 2, 4 to 6, and 8 to 10, the radiation device 10 may include: a rack base 103, and a rack 101 disposed on the rack base 103 and rotatably connected to the rack base 103. The gantry 101 is rotatable around a rotational axis of the gantry 101.

In the embodiment of the present invention, the first antenna 0011 in the first wireless transmission component 001 in the signal transmission device 00 may be disposed on the rack 101, the second antenna 0012 and the second wireless bridge 0014 may be disposed on the rack base 103, and the upper computer 30 may be disposed independently of the rack 101 and the rack base 103. Since the rack mount 103 may be located on the ground or on a carrying surface, the second antenna 0012 and the second wireless bridge 0014 located on the rack mount 103, as well as the upper computer 30 independent of the rack 101 and the rack mount 103, may remain stationary regardless of whether the rack 101 is rotating, with the cables between the second antenna 0012 and the second wireless bridge 0014, and between the second wireless bridge 0014 and the upper computer, not affecting the rotation of the rack 101.
