Description

Detailed Description
For a more complete and thorough description of the present application, reference is made to the accompanying drawings, wherein like reference numerals represent the same or similar elements, and in which are shown various embodiments of the present application. However, it will be understood by those of ordinary skill in the art that the examples provided below are not intended to limit the scope of the present application. Furthermore, the drawings are for illustrative purposes only and are not drawn to their original dimensions.
Embodiments of various aspects of the application are described in further detail below with reference to the drawings.
Fig. 1 is a schematic diagram showing a state of full duplex transmission of signals when an upper rotating body and a lower rotating body are relatively moved to a certain position in a wireless signal transmission apparatus of the related art. Fig. 2A is a schematic view showing a state in which a signal is transmitted from an upper rotating body to a lower rotating body when the wireless signal transmission apparatus of fig. 1 performs full duplex transmission. Fig. 2B is a schematic view showing a state in which a signal is transmitted from the lower rotating body to the upper rotating body when the wireless signal transmission apparatus of fig. 1 performs full duplex transmission.
Referring to fig. 1, 2A and 2B, the conventional wireless signal transmission apparatus includes a lower rotating body 1 and an upper rotating body 2. Wherein the lower rotating body 1 comprises a first transmitting unit 3 and a second receiving unit 4, and the upper rotating body 2 comprises a second transmitting unit 5 and a first receiving unit 6. When the lower rotating body 1 transmits a signal to the upper rotating body 2, the first transmitting unit 3 and the first receiving unit 6 form a transmission path, and the signal flows from bottom to top (as indicated by an arrow). Similarly, when the upper rotating body 2 transmits a signal to the lower rotating body 1, the second transmitting unit 5 and the second receiving unit 4 constitute a transmission path, and the signal flows from top to bottom (as indicated by an arrow).
As described in the background section, the emission range of a transmitting unit such as a spectrum emission tube is a cone, and the closer the position on the irradiation surface is to the center of the circular bottom surface, the higher the luminance is. As shown in fig. 2A, when the second transmitting unit 5 of the upper rotating body 2 transmits a signal to the second receiving unit 4 of the lower rotating body 1, since the second receiving unit 4 is substantially at the center of the circular bottom surface of the cone (as shown by the circular dotted line frame), the brightness is the strongest and the illumination intensity is the largest. Also, as shown in fig. 2B, when the first transmitting unit 3 of the lower rotating body 1 transmits a signal to the first receiving unit 6 of the upper rotating body 2, since the first receiving unit 6 is substantially at the center of the circular bottom surface of the cone (as shown by the circular dotted line frame), the brightness is the strongest and the illumination intensity is the largest.
Fig. 3 is a schematic view showing a state of full duplex transmission of a signal when the upper rotating body and the lower rotating body are relatively moved to another position in the wireless signal transmission apparatus of fig. 1. Fig. 4A is a schematic view showing a state in which a signal is transmitted from an upper rotating body to a lower rotating body when the wireless signal transmission apparatus of fig. 3 performs full duplex transmission. Fig. 4B is a schematic view showing a state in which a signal is transmitted from the lower rotating body to the upper rotating body when the wireless signal transmission apparatus of fig. 3 performs full duplex transmission.
However, when the relative rotation between the lower rotating body 1 and the upper rotating body 2 is made to rotate from the relative position shown in fig. 1 to the relative position shown in fig. 3, the position between the first transmitting unit 3 and the first receiving unit 6 is changed, and the position between the second transmitting unit 5 and the second receiving unit 4 is also changed. In other words, the first transmitting unit 3 is no longer directly opposite to the first receiving unit 6 in the vertical direction, and the second transmitting unit 5 is no longer directly opposite to the second receiving unit 4 in the vertical direction. As shown in fig. 4A and 4B, when the first receiving unit 6 and the second receiving unit 4 are laterally offset from the upper rotating body 2 and the lower rotating body 1, respectively, the receiving units are positioned gradually away from the center of the circular bottom surface of the cone shape corresponding to the transmitting unit, so that the illumination intensity is weak. Once the location of the receiving unit is on the circumference of the circular bottom surface, the lateral offset is maximized and the illumination intensity is minimized. In the relative rotation process, the voltage induced by photosensitive devices such as a photosensitive diode and the like is high and low, and the wireless communication rate is directly influenced.
In order to solve the above-mentioned drawbacks or disadvantages of the prior art, the present application provides an improved wireless signal transmission device structure. Fig. 5 is a schematic diagram showing that the upper rotating body and the lower rotating body perform full duplex transmission of signals when rotating relatively in the wireless signal transmission device according to an embodiment of the present application.
Referring to fig. 5, in this embodiment, the wireless signal transmission apparatus of the present application includes a first transmission device 1 and a second transmission device 2. Also, the first transmission device (i.e., the lower rotating body) 1 includes a first transmitting unit 3 and a second receiving unit, and the second transmission device (i.e., the upper rotating body) 2 rotates relative to the first transmission device 1. The second transmission device 2 comprises a first receiving unit 6 and a second transmitting unit. Wherein, the first transmitting unit 3 and the first receiving unit 6 adopt optical signals with a first wavelength for wireless signal transmission, and the second receiving unit and the second transmitting unit adopt optical signals with a second wavelength for wireless signal transmission, and the first wavelength is different from the second wavelength. In this way, since the light emitted by the first transmitting unit and the light emitted by the second transmitting unit are different in wavelength, they do not affect each other, that is, the first transmission path and the second transmission path perform signal transmission independently of each other. As can be seen from fig. 5, the first transmitting unit 3 and the first receiving unit 6 are always disposed facing each other regardless of the relative rotation of the upper and lower rotating bodies, the second transmitting unit includes a plurality of transmitting devices 51 to 54 and the second receiving unit includes a plurality of receiving devices 41 to 44, and these transmitting devices and receiving devices at corresponding positions perform signal transmission with optical signals of the second wavelength.
As can be seen from the above, the plurality of transmitting devices 51 to 54 of the second transmitting unit are electrically connected in parallel, and can be regarded as an integral transmitting ring; the plurality of receiving devices 41 to 44 of the second receiving unit are also connected in parallel in electrical connection and can be regarded as an integral receiving ring, so that the second receiving unit can receive as much stable and stronger light as possible, and the information transmission speed and stability are greatly improved.
In a specific embodiment, the first transmission device 1 and the second transmission device 2 are optical signal transceiver devices, which are disc structures that relatively rotate around the same rotation axis. For example, the first transmitting unit 3 is located at the center of the disc-shaped first transmission device 1, the first receiving unit 6 is located at the center of the disc-shaped second transmission device 2, and the center of the first transmission device 1 and the center of the second transmission device 2 are located at the rotation axis. It will be appreciated by those skilled in the art that the first and second transfer devices 1 and 2 may be any shape, such as square, oval, polygonal, etc., in addition to being designed as a disc structure. Preferably, the plurality of receiving devices 41 to 44 of the second receiving unit are uniformly distributed along a circumference centered on the first transmitting unit 3, and the plurality of transmitting devices 51 to 54 of the second transmitting unit are uniformly distributed along a circumference centered on the first receiving unit 6. If the number of receiving devices is 4, the positions of two adjacent receiving devices are circumferentially spaced by 90 degrees.
In a specific embodiment, the first transmitting unit and the second transmitting unit are both injection type semiconductor light emitting devices, semiconductor laser devices or photoelectric coupling devices. The injection type semiconductor light emitting device is a light emitting diode, a nixie tube, a symbol tube, a Chinese character 'mi' tube or a matrix tube. In addition, the first receiving unit and the second receiving unit are photodiodes, avalanche diodes, phototriodes, photosensitive field effect transistors or photoresistors.

Finally, a first transmission path is established by the first transmitting unit 3 and the first receiving unit 6, and a second transmission path is established by the second transmitting unit and the second receiving unit. Wherein the signal flow direction of the second transmission path is opposite to the signal flow direction of the first transmission path (i.e. full duplex signal transmission mode), and the first transmission path or the second transmission path coincides with the rotation axis. It will be appreciated by those skilled in the art that in other embodiments, the first transmitting unit and the first receiving unit may be disposed at the rotation axis, and the second transmitting unit and the second receiving unit in this case include a plurality of transmitting devices and a plurality of receiving devices, respectively; in other embodiments, the second transmitting unit and the second receiving unit may be disposed at the rotation axis, and the first transmitting unit and the first receiving unit at this time include a plurality of transmitting devices and a plurality of receiving devices, respectively.
