Description

Technical Field

[0001] The present invention belongs to the technical field of signal transmission, and in particular relates to an optical fiber transmitter based on signal processing. Background Art

[0002] A fiber transmitter is a device used to convert electrical signals into optical signals and transmit them through optical fibers (optical fibers). It has the following characteristics and uses: High data transmission rate: Data transmission using optical fibers can reach very high rates, and the data transmission rate of a single optical fiber can reach several Gbps or even higher; Long-distance transmission: Fiber transmission can achieve a transmission distance of tens of kilometers without the need for repeaters; Multiple signal transmission: Optical fibers can not only transmit digital signals, but also analog signals and video signals to meet different communication needs; Strong anti-interference performance: Since optical fibers use optical signal transmission, they are not easily affected by electromagnetic interference, ensuring the stability and reliability of transmission.

[0003] As an important part of the optical fiber communication system, the optical fiber transmitter does have some defects, mainly including:

[0004] Inconvenient access: In buildings, optical fibers need to use active devices (such as optical transceiver converters) to convert optical signals into electrical signals for computer network cards. This means that if the optical transceiver loses power, the network connection of the entire building will be interrupted. In addition, once the optical transceiver converter in the device fails, the device will also stop working. However, existing optical fiber transmitters do not have backup measures to deal with the above unexpected situations, causing the network to be interrupted and a large amount of information data to be lost.

[0046] Embodiment 1:

[0047] Refer to the attached Figure 1-Figure 3 A power socket 101, an optical fiber socket 102 and a status indicator light 103 are fixedly provided at one end of the transmitter housing 1, a conversion interface 104 is fixedly provided at the other end of the transmitter housing 1, equipment cavities 105 for installing the conversion housing 2 are provided inside the upper and lower sides of the transmitter housing 1, adapter cavities 112 for installing the power and signal conductor 3 and the driving mechanism 4 are provided at both ends of the interior of the transmitter housing 1, and battery chambers 107 for installing the battery 6 are provided on both sides of the interior of the transmitter housing 1.

[0048] Refer to the attached Figure 2-Figure 4 A connector 106 is provided in the middle of both ends of the inner wall of the equipment cavity 105, and a connector 108 is provided at both ends of the top and bottom of the two transition cavities 112 near the middle of the side wall of the equipment cavity 105, and the connector 108 and the corresponding connector 2 106 are an integrated structure, and a connector 3 109 is provided in the middle of the side wall of the two transition cavities 112 away from the equipment cavity 105.

[0049] Refer to the attached Figure 4-Figure 5 Both ends of the top and bottom of the transfer cavity 112 are assembled with elastic clamping rods 111 through fixed columns 110.

[0050] Refer to the attached Figure 2 A heat dissipation port 201 is provided at one end of the outer surface of the conversion housing 2, and a connector 202 for contacting and connecting with the connector 2 106 is provided in the middle of the side walls at both ends of the conversion housing 2. A buckle 203 is fixedly provided on the inner surface of both ends of the conversion housing 2, and the buckle 203 extends to the inside of the corresponding adapter cavity 112, and the corresponding elastic clamping rod 111 clamps the buckle 203 when squeezed by the corresponding power and signal conductor 3.

[0051] Refer to the attached Figure 5-Figure 6A connecting groove 301 for contacting and connecting with the corresponding connecting body 3 109 is formed through the outer wall of one side of the power and signal conductor 3, and a connecting half groove 302 for contacting and connecting with the corresponding connecting body 1 108 is formed on the upper and lower outer walls of the other side of the power and signal conductor 3. A connecting body 5 303 is connected to the inner wall of one side of the power and signal conductor 3 at the position corresponding to the connecting groove 301, and a connecting body 6 304 is connected to the inner wall of the other side of the power and signal conductor 3 at the position corresponding to the connecting half groove 302. A conducting body 305 is slidably assembled inside the power and signal conductor 3. The conducting body 305 is slidably assembled with the connecting body 5 303 and the conducting body 305 is slidably assembled with the connecting body 6 304. A pressing frame 313 for pressing the corresponding elastic clamping rod 111 is fixedly arranged at both ends of the top and bottom of the power and signal conductor 3.

[0052] According to the above structure, the two conversion housings 2 located inside the two equipment chambers 105 are both used to complete the conversion between optical signals and electrical signals, and the two can be used interchangeably when one of them fails. The specific replacement process is as follows: the two sets of driving mechanisms 4 located inside the two switching chambers 112 simultaneously control the two power and signal conductors 3 to move up and down at the same time, such as Fig. 9 As shown, the two power and signal conductors 3 are controlled to move downward together, the connection half groove 302 located at the bottom contacts the connector 1 108 located at the bottom, and the connection through groove 301 is in sliding contact with the connector 3 109 at all times to ensure that the current and signal enter the connector 5 303 in the power and signal conductor 3, and then are transmitted to the input end of the conversion housing 2 located below through the conductive body 305, the connector 6 304 and the connector 1 108. After the current enters the interior of the conversion housing 2, it is used to provide electrical energy, and the electrical signal or optical signal is output through its output end after being photoelectrically converted. The above structure enables the optical fiber transmitter to have a spare device for processing photoelectric conversion, which solves the problem that the traditional optical fiber transmitter cannot be used once it fails. When one of the conversion housings 2 fails, the other conversion housing 2 will take over and continue to perform signal processing. The detachable conversion housing 2 is more convenient for disassembly and maintenance when a failure occurs, and the disassembly process does not require stopping the operation of the optical fiber transmitter.

[0053] In addition, when a conversion housing 2 is in use, the power and signal conductor 3 moves to one end of the conversion housing 2 and squeezes the corresponding elastic clamping rod 111. The two ends of the elastic clamping rod 111 will extend and clamp the main buckle 203, thereby fixing the conversion housing 2 in use, thereby avoiding accidental removal of the conversion housing 2 in use during disassembly and maintenance, and avoiding accidental stop of optical fiber transmission due to misoperation.

[0054] The working principle of the present invention is as follows: the two conversion housings 2 located inside the two equipment cavities 105 are both used to complete the conversion between optical signals and electrical signals, and the two can be used in succession when one of them fails. The specific succession process is as follows: the two sets of driving mechanisms 4 located inside the two switching cavities 112 simultaneously control the two power and signal conductors 3 to move up and down at the same time, such as Fig. 9 As shown, the two power and signal conductors 3 are controlled to move downward together, the connecting half groove 302 located below is in contact with the connector 1 108 located below, and the connecting through groove 301 is in sliding contact with the connector 3 109 at all times to ensure that the current and signal enter the connector 5 303 in the power and signal conductor 3, and then are transmitted to the input end of the conversion housing 2 located below through the conductive body 305, the connector 6 304 and the connector 1 108. After entering the interior of the conversion housing 2, the current is used to provide electrical energy, and the electrical signal or optical signal is output through its output end after being photoelectrically converted.

[0058] Refer to the attached Figure 7-Figure 8A rotating arm 407 is symmetrically assembled inside the transfer cavity 112 and located at both ends of the power and signal conductor 3. The end of the rotating arm 407 away from the transfer point is movably inserted into the inside of the corresponding transverse groove body 309, one of the rotating arms 407 is fixedly connected to the end of the end shaft 403, and a connecting shaft 413 is assembled at the upper part of the transfer cavity 112, and the connecting shaft 413 and the rotating arms 407 at both ends are connected through a belt 414.

[0059] Refer to the attached Figure 7-Figure 8 The outer surface of the output shaft of the motor 401 is slidably assembled with a wedge gear four 409 that is detachably meshed with the wedge gear three 408, and a baffle two 411 is fixedly provided at one end of the output shaft of the motor 401 away from the wedge gear three 408, and a spring two 412 is provided between the baffle two 411 and the wedge gear four 409, and a narrow gear 410 is fixedly sleeved on the outer surface of the wedge gear four 409, and a wide gear 420 that is rotatably assembled and meshes with the narrow gear 410 is inside the transfer cavity 112 and located on one side of the motor 401.

[0060] Refer to the attached Figure 7-Figure 8 , inside the transfer cavity 112 and located on both sides of the power and signal conductor 3, a vertical slot plate 415 is assembled horizontally and slidingly, and the vertical slot plate 415 is placed between the transverse slot plate 308 and the transverse slot body 309, and the end of the through rod 312 penetrates the corresponding transverse slot plate 308 and the vertical slot plate 415, and a side vertical slot 416 is opened on one side of the vertical slot plate 415, and inside the transfer cavity 112 and located at both ends of the power and signal conductor 3, a second rotating arm 417 is assembled symmetrically and rotatably, and the end of the second rotating arm 417 away from the transfer point is movably inserted into the corresponding side vertical slot 416, and a second connecting shaft 418 is assembled and rotated at the bottom of the transfer cavity 112, and the second connecting shaft 418 and the second rotating arms 417 at both ends are connected by a sleeved belt 419, and one end of the second connecting shaft 418 is connected to the wide gear 420 by a sleeved belt 3 421.

[0061] Refer to the attached Fig.11 A temperature sensor 51 for detecting the internal temperature of the transmitter housing 1 is installed on one side of the safety chip 5, and an abnormal information receiving module 52, a power supply detection module 53, a motor drive module 54 and a backup power supply module 55 are arranged inside the safety chip 5.

[0062] Scenario 1: When the abnormal information receiving module 52 detects that the working conversion housing 2 is in an abnormal state, the light bulb corresponding to the status indicator light 103 will light up, and the motor driving module 54 will also be triggered to start the motor 401. The motor 401 will rotate forward at this time, and the wedge gear 1 402 will carry the wedge gear 2 404 to rotate together, and the wedge gear 4 409 will just slide back and forth and continuously squeeze the spring 2 412. Through the transmission of the belt 1 414 and the connecting shaft 1 413, the rotating arms 1 407 at both ends rotate together. Since the end of the rotating arm 1 407 is inserted into the horizontal groove body 309, the power and signal conductor 3 can move up and down reciprocatingly. At this time, the output time of the motor 401 is controlled so that the power and signal conductor 3 moves to the specified position and then stops. At this time, the other conversion housing 2 can be in state and used;

[0063] Scenario 2: When the power supply detection module 53 detects that the input voltage is abnormal, the motor drive module 54 will also be triggered and start the motor 401. The motor 401 will reverse at this time, and the wedge gear three 408 will carry the wedge gear four 409 to rotate together, while the wedge gear two 404 will just slide back and forth and continuously squeeze the spring one 406. Through the meshing of the narrow gear 410 and the wide gear 420, as well as the transmission of the belt three 421 and the connecting shaft two 418, the rotating arms two 417 at both ends rotate together. Since the end of the rotating arm two 417 is inserted into the side vertical slot 416, the vertical slot plate 415 carries the vertical slot plate 415. The belt frame 310 reciprocates horizontally, and at this time, the output time of the motor 401 is controlled, so that the frame 310 carries the magnet 2 311 to move to the specified position and then stops. Under the attraction of the magnet 1 306 and the magnet 2 311, the conductive living body 305 will move and separate from the connector 6 304, and the operation of the conversion housing 2 can be stopped at this time. This process can timely prevent abnormal current from flowing into the working conversion housing 2, and can timely stop the operation of the optical fiber transmitter when abnormal current and voltage are found, so as to avoid damage to the internal module of the conversion housing 2 and minimize the damage to the equipment;

[0064] Scenario 3: When the temperature sensor 51 senses that the temperature inside the transmitter housing 1 is too high, the motor drive module 54 is triggered and starts the motor 401 to reverse, which is the same as the process in Scenario 2. This process can stop the operation of the transmitter housing 1 in time when the internal temperature of the device rises suddenly due to long-term operation or other factors, so as to avoid the device from continuing to work and generating more heat and causing damage to the device;

[0065] Scenario 4: When the optical fiber transmitter is suddenly powered off, the backup power supply module 55 is triggered and the battery 6 is used as a backup power source for emergency power supply, so as to extend the working time of the equipment after the power failure as much as possible and facilitate continued operation during power restoration.

[0066] The working principle of the present invention is as follows: the setting of the safety chip 5 enables the optical fiber transmitter to promptly put another conversion housing 2 into use when one conversion housing 2 is found to be working abnormally, and can also promptly stop the optical fiber transmitter from continuing to work when power supply abnormalities and temperature abnormalities occur in the optical fiber transmitter.

Nonlinear optical devices such as fiber gratings in the nonlinear distortion suppression module 233 can effectively suppress nonlinear distortion and improve the transmission quality of the signal.

These two devices are the key parts for realizing photoelectric conversion and electro-optical conversion in optical fiber communication. The laser driver 221, limiting amplifier 222 and controller 223 in the functional circuit 22 support different rates and transmission distances to ensure accurate transmission and processing of signals.
