[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] like Figures 1 to 4 As shown, the embodiment of the utility model provides an information transmission system, which includes: an information collector 1, a first converter 2, a switch 5, an optical fiber component 3, a second converter 4, a processor 6 and a control device 7, specifically:

[0027] like Figure 1 As shown, Figure 1The present invention is an electrical equipment connection diagram of an information transmission system according to an embodiment of the present utility model. An information collector 1 is used to collect a first digital signal containing target information; a first converter 2 is connected to the information collector 1 and is used to convert the first digital signal into an optical signal; an optical fiber component 3 is connected to the first converter 2 and is used to transmit an optical signal, wherein the optical fiber component 3 includes a main optical fiber 31 and a backup optical fiber 32, and the main optical fiber 31 and the backup optical fiber 32 are placed in parallel; a second converter 4 is connected to the optical fiber component 3 and is used to receive the optical signal transmitted by the optical fiber component 3 and convert the received optical signal into a second digital signal; a processor 6 is connected to the second converter 4 and is used to receive the second digital signal and control the opening and closing of the control device 7 according to the second digital signal; a switching switch 5 is installed between the optical fiber component 3 and the first converter 2 and is connected to the second converter 4 and is used to control the connection status of the first converter 2 with the main optical fiber 31 and the backup optical fiber 32 respectively according to the second digital signal converted by the second converter 4.

[0028] The information transmission system provided by this embodiment is applied, and the information transmission system includes: the information collector 1 collects the first digital signal containing the target information and transmits it to the first converter 2; the first converter 2 converts the first digital signal into an optical signal and transmits it to the optical fiber 3; the optical fiber 3 transmits the optical signal from one end of the first converter 2 to one end of the second converter 4; the second converter 4 converts the received optical signal into a second digital signal and transmits it to the processor 6; the processor 6 controls the opening and closing of the control device 7 according to the received second digital signal, wherein the control device 7 is the electrical equipment to be controlled. Based on the above process, the technical effect of interconnection and communication between electrical equipment is achieved by transmission through the optical fiber 3, thereby solving the technical problem of poor information transmission capability between electrical equipment in remote sites due to the lack of Ethernet and 5G communication conditions.

[0029] It should be noted that electrical equipment refers to equipment that is powered by electricity, that is, equipment that can be used by connecting to a power source.

[0030] Among them, the optical fiber component 3 includes a main optical fiber 31 and a spare optical fiber 32. In this embodiment, the main optical fiber 31 adopts a single-mode optical fiber. The single-mode optical fiber is an optical fiber with a very small core diameter, and its core is generally 8-10 microns. Since the core diameter of the single-mode optical fiber is very small, the probability of multiple reflections and refractions of the optical signal in the single-mode optical fiber during its transmission is low, so the loss during the transmission of the single-mode optical fiber is very low, which effectively ensures the low loss rate of the optical signal during the transmission process, so that when the second converter 4 receives the optical signal and converts it into a second digital signal, the probability that the second digital signal is the same as the first digital signal increases, thereby ensuring the integrity of the information transmission during the transmission process. In addition, the single-mode optical fiber has a higher bandwidth and can transmit higher frequency optical signals, that is, fast transmission, can transmit more information, and can transmit optical signals over long distances, usually up to tens of kilometers or even hundreds of kilometers. Generally, Ethernet communication transmission refers to long-distance transmission. In the absence of Ethernet communication conditions, long-distance transmission can be achieved through single-mode optical fiber, which can effectively ensure the distance of the transmission signal and the speed of the transmission signal.

[0031] Among them, the spare optical fiber 32 adopts redundant optical fiber, which can adopt single-mode optical fiber or low-cost plastic optical fiber. When the main optical fiber 31 is damaged and the second converter 4 cannot receive the optical signal, the state of the first converter 2 connected with the main optical fiber 31 is switched to the state of the first converter 2 with the spare optical fiber 32 by switching the switch 5, which effectively avoids the main optical fiber 31 being damaged and unable to transmit during the target information transmission process, and realizes multiple guarantees during the transmission process. It should be noted that in the process of the main optical fiber 31 transmitting the optical signal to the second converter 4, due to the refraction of the optical signal, when reaching the second converter 4, a small amount of the optical signal will be refracted into the spare optical fiber 32, and return to the first converter 2 through the spare optical fiber 32. When the first converter 2 cannot normally receive the optical signal refracted by the spare optical fiber 32 for a long time, it means that the second converter 4 cannot receive the optical signal. At this time, the switching switch 5 switches the connection state of the first converter 2 with the main optical fiber 31 and the spare optical fiber 32 respectively.

[0032] Among them, the failure to normally receive the optical signal refracted by the spare optical fiber 32 for a long time means that the time of general optical signal transmission depends on the speed of light and the transmission distance. In a vacuum, the speed of light is about 299792458 meters per second, so the time of optical signal transmission can be calculated by dividing the distance by the speed of light. For example, if the optical signal needs to be transmitted for 1000 meters, the transmission time is about 0.000003335 seconds, that is, 3.335 milliseconds. When transmitting in the optical fiber 3, the optical signal will be subject to some attenuation and delay, so the transmission time will increase slightly, and the increased time is generally about one millisecond. In the process of one kilometer transmission, the optical fiber transmission time of the optical signal is about 4 milliseconds to 5 milliseconds. After refraction, it is the round-trip distance. The time received by the first converter 2 is about 10 milliseconds. Considering that there will be a few optical signals that fail to be refracted into the spare optical fiber 32, it is preset that one out of every three optical signals transmitted will be refracted. Then, the first converter 2 fails to receive the optical signal refracted in the spare optical fiber 32 every 30 milliseconds. At this time, it is judged that the second converter 4 fails to receive the optical signal, and the switch 5 is switched at this time. It should be noted that the long time during which the refracted light signal of the backup optical fiber 32 cannot be received is a preset value set according to the distance and can be adjusted according to the actual situation on site. The above calculation method and calculation results are not calculated by software.

[0033] like Figure 1 As shown, multiple information collectors 1 are provided, and the information transmission system also includes a multiplexer 8 and a demultiplexer 9, wherein the multiplexer 8 is installed between the multiple information collectors 1 and the first converter 2, and is used to merge the first digital signals respectively acquired by the multiple information collectors 1 into an integrated signal, and transmit the integrated signal to the first converter 2; the demultiplexer 9 is installed between the second converter 4 and the processor 6, and is used to decompose the integrated signal into multiple second digital signals, and transmit the multiple second digital signals to the processor 6.

[0034] With the above structure, considering that multiple information needs to be transmitted to the receiving end over a long distance, it is necessary to transmit through the same single-mode optical fiber. The first digital signals collected by multiple information collection devices need to be collected by multiplexers 8 into an integrated signal for subsequent transmission. This method can avoid the situation where multiple first digital signals need to be transmitted. If a single first digital signal is used for transmission, multiple first digital signals will be in a queue. The method of collecting multiple first digital signals into an integrated signal for transmission effectively improves the transmission rate. When the integrated signal is transmitted to one end of the second converter 4 through the optical fiber 3, it becomes a second collective signal. The second collective signal is split into multiple second digital signals by the demultiplexer 9, thereby achieving the effect of simultaneously transmitting multiple target information collected by multiple information collection devices, effectively improving the efficiency of target information transmission.

[0035] like Figure 1 As shown, the information transmission system further includes a grating isolator 10, wherein the grating isolator 10 is installed between the first converter 2 and the main optical fiber 31, and is used to block the refracted signal generated by the optical signal emitted by the first converter 2 from returning to the first converter 2 after being refracted.

[0036] With the above structure, due to the refraction phenomenon of the optical signal in the main optical fiber 31, part of the optical signal is refracted back to the first converter 2 during the transmission of the optical signal in the main optical fiber 31, wherein the optical signal is transmitted in the form of a light source, and the above-mentioned returning light source will damage the device of the light source emitting inside the first converter 2, so a grating isolator 10 is set at the first converter 2 to block the light source refracted in the main optical fiber 31 from returning to the first converter 2, effectively realizing the safe and stable operation of the entire system. It should be noted that part of the optical signal in the redundant optical fiber will reach the second converter 4 and return to the first converter 2 after the refracted light source generated by the refraction, and since the first converter 2 aligns the device of the light source emitting at the main optical fiber 31 by switching the switch 5 at this time, the refracted light source refracted in the redundant optical fiber to the first converter 2 will not damage the device of the light source emitting in the first converter 2, so there is no need to set a grating isolator 10 at the redundant optical fiber, and only one grating isolator 10 is set in the entire system, effectively achieving the effect of cost reduction.

[0037] like Figure 1 As shown, the information transmission system also includes a plurality of temperature sensors 11 and an alarm 12, wherein the plurality of temperature sensors 11 are respectively installed at a first predetermined position on the main optical fiber 31, and are used to collect temperature information on the main optical fiber 31, wherein the plurality of temperature sensors 11 are evenly distributed on the main optical fiber 31; the processor 6 is also respectively connected to the plurality of temperature sensors 11, and is used to receive temperature information; the processor 6 is connected to the alarm 12, and is used to control the opening and closing of the alarm 12 according to the temperature information.

[0038] With the above structure, since the performance of the optical fiber component 3 is affected by temperature, the refractive index of the optical fiber component 3 will change in a high temperature environment, resulting in changes in the transmission speed and transmission loss of the optical signal. At the same time, high temperature will also cause the expansion and deformation of the optical fiber component 3, thereby affecting the transmission performance of the optical fiber component 3. In addition, the optical fiber will also be affected in a low temperature environment. At low temperatures, the optical fiber component 3 will become fragile and prone to breakage, thereby affecting the transmission of the optical signal. Therefore, when using the optical fiber component 3 for transmission, the influence of temperature on the performance of the optical fiber component 3 must be considered. Therefore, a temperature sensor 11 is set on the main optical fiber 31 to detect the temperature of the main optical fiber 31 in real time, and the temperature information obtained by the real-time detection is transmitted to the processor 6. The processor 6 controls the opening of the alarm 12 according to the temperature information, when the temperature information exceeds the preset range value, to remind the staff to check in time and take corresponding measures. According to the real-time monitoring of the temperature during the transmission of the optical fiber component 3, the stability of the transmission of the optical fiber component 3 is effectively guaranteed.

[0039] like Figure 1 As shown, the information transmission system also includes a combiner 13, wherein the combiner 13 is installed between the main optical fiber 31 and the second converter 4, and is used to aggregate the optical signal transmitted by the main optical fiber 31 to obtain an aggregated signal; the second converter 4 is also used to convert the aggregated signal into a second digital signal.

[0040] With the above structure, during the transmission of the optical signal by the optical fiber component 3, the optical signal will be offset due to the vibration of the optical fiber component 3, and even the diffusion of the optical signal will be generated, which will cause the incomplete transmission of the optical signal after the diffusion. Therefore, a combiner 13 is arranged between the main optical fiber 31 and the second converter 4. The combiner 13 is used to aggregate the optical signal diffused due to the vibration during the transmission of the main optical fiber 31 to form an aggregated signal, thereby ensuring the integrity of the optical signal to the greatest extent, thereby effectively achieving the accuracy of the target information transmission. In addition, a vibration sensor is arranged on the main optical fiber 31, and the vibration sensor is used to obtain the vibration information on the main optical fiber 31. The vibration sensor is connected to the processor 6, and the processor 6 is connected to the combiner 13. The vibration sensor transmits the acquired vibration information to the processor 6, and the processor 6 receives the vibration information and controls the opening and closing of the combiner 13 according to the vibration information. When the main optical fiber 31 is affected by the vibration, the combiner 13 is enabled to aggregate the diffused optical signal, thereby effectively ensuring the integrity of the optical signal received by the second converter 4.

[0041] like Figure 2 As shown, Figure 2It is a structural diagram of a protective sleeve 14 of an information transmission system according to an embodiment of the utility model. The information transmission system also includes a protective sleeve 14 and a plurality of fixings 15, wherein the protective sleeve 14 is installed on the outside of the optical fiber component 3; the plurality of fixings 15 are installed on the ground at one end and connected to the protective sleeve 14 at the other end, and the plurality of fixings 15 are evenly distributed along the axial direction of the protective sleeve 14.

[0042] With the above structure, the optical fiber component 3 can be buried below the ground or installed above the ground. The buried below the ground means digging at least half a meter below the ground to place the optical fiber component 3 therein, and a buried mark is made every ten meters along the direction of the optical signal transmitted by the optical fiber component 3. The buried mark needs to indicate the information that the optical fiber component 3 is installed here, so that when the optical fiber component 3 is damaged later, the staff can check it according to the buried mark. In the case where there are no obstructions on the ground or it is difficult to dig below the ground, the optical fiber component 3 is installed above the ground. This method can facilitate the staff to check the failure of the optical fiber component 3 later, and the ground does not need to be dug for troubleshooting, which greatly reduces the difficulty of troubleshooting and increases the efficiency of troubleshooting. However, since the optical fiber component 3 is easily damaged, a protective sleeve 14 is provided on the outside of the optical fiber component 3, and a fixing member 15 is provided to fix the protective sleeve 14, thereby effectively protecting the optical fiber component 3. It should be noted that, when there are obstacles above the ground and it is difficult to dig below the ground, the fixing member 15 can be provided in the form of a support frame to raise the optical fiber component 3 to a certain height so as to pass over the obstacle. If there are no obstacles above the ground, the fixing member 15 only needs to fix the protective sleeve 14 to the ground to ensure that the protective sleeve 14 does not move.

[0043] like Figure 3 As shown, Figure 3 The figure is an internal structure diagram of a straight sleeve 16 of an information transmission system according to an embodiment of the utility model. The protective sleeve 14 includes a straight sleeve 16 and a bent sleeve 17, wherein the straight sleeve 16 is parallel to the straight part of the optical fiber component 3, and the straight sleeve 16 includes an outer tube 18, an inner tube 19 and a plurality of support rods 20, the inner tube 19 is arranged between the optical fiber component 3 and the outer tube 18, and the plurality of support rods 20 are arranged between the inner tube 19 and the outer tube 18, and the plurality of support rods 20 are arranged in a ring shape around the inner tube 19 axially; the inner tube 19 includes a plurality of air-permeable holes; the bent sleeve 17 is parallel to the bent part of the optical fiber component 3, and the bent sleeve 17 includes a bent tube 22 and a connector 23, the connector 23 is installed between the outer tube 18 and the bent tube 22, and the bent tube 22 is provided with a plurality of retractable curved surfaces.

[0044] With the above structure, the protective sleeve 14 provides protection for the optical fiber component 3. When the optical fiber component 3 encounters a change in the transmission direction of the optical signal, the optical fiber component 3 also needs to adaptively adjust its direction to achieve the effect of changing the transmission direction of the optical signal. At this time, the optical fiber component 3 has a certain degree of bending, and the bending part also needs to be protected, that is, the protective sleeve 14 is set to two parts: a straight sleeve 16 and a bending sleeve 17. The straight sleeve 16 is used to be installed in the straight part of the optical fiber component 3 to protect the straight part of the optical fiber component 3, and the bending sleeve 17 is used to be installed in the bending part of the optical fiber component 3 to protect the bending part of the optical fiber component 3.

[0045] Specifically, since the optical fiber component 3 has a heat dissipation phenomenon during operation, if the protective sleeve 14 is tightly attached to the optical fiber component 3 and is airtight, the heat dissipation of the optical fiber component 3 cannot be effectively discharged, which will cause the optical fiber component 3 to continue to heat up, resulting in an overly high temperature of the optical fiber component 3, thereby affecting the rate at which the optical fiber component 3 transmits optical signals. Therefore, the straight sleeve 16 is provided with an inner tube 19 and an outer tube 18. The inner tube 19 is attached to the outer side of the optical fiber component 3 to fix the optical fiber component 3. The inner tube 19 is provided with a plurality of air holes to effectively achieve the heat dissipation of the optical fiber component 3, wherein the plurality of air holes are evenly distributed on the surface of the inner tube 19. Since the inner tube 19 is provided with ventilation holes, when the inner tube 19 is exposed to the outside, the ventilation holes are in contact with the outside, and the optical fiber 3 cannot be fully protected. Therefore, the outer tube 18 is provided outside the inner tube 19, and the outer tube 18 is not in contact with the inner tube 19, that is, there is a gap between the inner tube 19 and the outer tube 18. This setting is to ensure that the heat dissipated from the ventilation holes enters the gap between the inner tube 19 and the outer tube 18, thereby achieving heat diffusion. However, since there is a gap between the inner tube 19 and the outer tube 18, the inner tube 19 can move inside the outer tube 18. Since the optical fiber 3 is prevented from being collided or moved, a support rod 20 is provided between the inner tube 19 and the outer tube 18. The support rod 20 is used to fix the inner tube 19 at a preset position inside the outer tube 18, effectively ensuring the fixation of the optical fiber 3 and achieving protection of the straight-moving part of the optical fiber 3.

[0046] A bending sleeve 17 is provided at the bending part, and the bending sleeve 17 includes a bending tube 22 with multiple retractable curved surfaces and a connector 23 connecting the bending tube 22 with the outer tube 18. The diameter of the bending tube 22 is the same as the diameter of the outer tube 18. Internal threads are provided at both ends of the connector 23. External threads are provided at both ends of the bending tube 22 and the outer tube 18. The three are connected by rotating the threads. The retractable curved surface of the bending tube 22 is similar to the bending part of a straw, and can be stretched and bent. By bending the bending tube 22, it is adjusted to an angle that adapts to the deflection of the optical fiber component 3, thereby achieving the effect of protecting the bending part of the optical fiber component 3.

[0047] The information transmission system also includes a first chassis 24 and a second chassis 25 , wherein the multiplexer 8 , the grating isolator 10 , and the first converter 2 are installed in the first chassis 24 , and the combiner 13 , the second converter 4 , the demultiplexer 9 , and the processor 6 are installed in the second chassis 25 .

[0048] like Figure 4 As shown, Figure 4 This is a distribution diagram of the first chassis and the second chassis in an information transmission system according to an embodiment of the utility model. The above structure is adopted to protect all devices in the information transmission system. By setting the first chassis 24 and the second chassis 25, the first chassis 24 is set at the first digital signal sending end, and the multiplexer 8, the grating isolator 10, and the first converter 2 are installed in the first chassis 24. The second chassis 25 is set at the second digital signal receiving end, and the combiner 13, the second converter 4, the multiplexer 8 and the processor 6 are all installed in the second chassis 25, which effectively realizes the protection of all devices in the information transmission system. Since the optical signal is sent and received, it is treated as far as possible to avoid light, and the external light affects the optical signal, the first chassis 24, the second chassis 25 and the outer tube 18 are set to be light-proof to avoid the external light from affecting the target information transmission process.

[0049] like Figure 1 As shown, the information collector 1 includes a water level sensor 101, and the control device 7 includes an electric water pump 71, wherein the water level sensor 101 is installed in the water tank 27, and is used to collect a first digital signal containing target information in the water tank 27, wherein the target information is the water level information in the water tank 27; the processor 6 is connected to the electric water pump 71, and is used to control the opening and closing of the electric water pump 71 according to the second digital signal; the electric water pump 71 is installed in the reservoir 29, and is used to transmit the water source in the reservoir 29 to the water tank 27 through the water source pipe 28.

[0050] With the above structure, this embodiment is applied to areas with poor signal communication such as the salt lake in the Qaidam Basin. For the transmission of water source dispatching information, a water storage tank 27 is used to store water at the end far away from the water source. When the water source in the water storage tank 27 is lower than the preset water level, the water source in the water storage tank 27 is insufficient, and the water source in the remote reservoir 29 needs to be dispatched to the water storage tank 27. The information collector 1 uses a water level sensor 101 to detect the target information in the water storage tank 27, that is, the water level information, and sends the water level information to the first converter in the form of a first digital signal. Converter 2, the first converter 2 converts the first digital signal into an optical signal and transmits it in a single-mode optical fiber. The single-mode optical fiber transmits the optical signal to the second converter 4. The second converter 4 converts the optical signal into a second digital signal containing water level information and sends it to the processor 6. The processor 6 receives the water level information in real time. When the water level information is lower than the preset water level, the electric water pump 71 is controlled to transport the water source in the reservoir 29 to the water storage tank 27 through the water source pipe 28, thereby completing the effect of remote water scheduling and effectively realizing the interconnection between electrical equipment.

[0051] like Figure 1 As shown, the information collector 1 also includes a water flow sensor, wherein the water flow sensor is installed in the water source pipe 28 and is used to collect water flow information in the water source pipe 28; the processor 6 is connected to the water flow sensor and is used to control the opening and closing of the alarm 12 according to the water flow information.

[0052] The above structure is adopted to avoid the situation where the electric water pump 71 fails and cannot transport the water in the reservoir 29 to the water storage tank 27 through the water source pipe 28. The water flow information in the water source pipe 28 is detected, where the water flow information can be the water flow rate, that is, whether there is water flowing continuously in the water source pipe 28 to the water storage tank 27. When the water flow rate is too low or even zero, the water in the water source pipe 28 is not transmitted to the water storage tank 27. The processor 6 controls the alarm 12 to sound an alarm, and the staff checks the fault condition of the electric water pump 71 in time, and ensures that the fault status is monitored during the water source scheduling process, thereby effectively achieving the effect of remote water scheduling.

[0053] The device provided by the embodiment has the following beneficial effects:

[0054] (1) The technical effect of interconnection and communication between electrical equipment is achieved by transmitting through the optical fiber 3, thereby solving the technical problem of poor information transmission capacity between electrical equipment in remote sites due to the lack of Ethernet and 5G communication conditions.

[0055] (2) Long-distance transmission can be achieved through single-mode optical fiber, which can effectively ensure the distance and speed of the transmission signal.

[0056] (3) By switching the switch 5, the state in which the first converter 2 is connected to the main optical fiber 31 is switched to the state in which the first converter 2 is connected to the backup optical fiber 32, thereby effectively avoiding the situation in which the main optical fiber 31 is damaged and unable to transmit during the target information transmission process, thereby achieving multiple protections during the transmission process.

[0057] Based on the above embodiments and optional embodiments, the utility model proposes an optional implementation method. This embodiment takes the difficulties in remote water dispatching faced in the Qarhan Salt Lake area of ​​the Qaidam Basin as an example. The hardware of the electrical equipment at the water intake end does not have Ethernet communication function, and is not within the coverage of the 5G signal, and there is no industrial Ethernet system at the water intake end, making it difficult to realize the transmission of information between electrical equipment.

[0058] Figure 5 is an optional electrical equipment connection diagram in an information transmission system according to an embodiment of the utility model, such as Figure 5 As shown, the system includes a water level sensor 101, i.e., a liquid level meter 102, a first isolator 1001, an alarm 12, i.e., an audible and visual alarm 121, a first converter 2, i.e., an electric / optical converter 201, a single-mode optical fiber, a second converter 4, i.e., an optical / electrical converter 41, a second isolator 1002, a processor 6 (PLC), an on-off switch, i.e., a traction device 26, an electric water intake pump 71, a water source pipeline 28, and a water storage tank 27.

[0059] In the process of dispatching water for production fire fighting in the Qinghai Salt Lake area, the distance between the water tank 27 and the reservoir 29 is about 3km. The distance between the water tank 27 and the reservoir 29 is relatively far, and the automation technical professionals who maintain the electrical equipment are insufficient. Long-distance information transmission and automated dispatching of water are carried out. The liquid level meter 102 is placed in the water tank 27 and is used to detect the water level information in the water tank 27. The liquid level meter 102 outputs a first digital signal with water level information. The liquid level meter 102 is connected to the first isolator 1001. The first isolator 1001 improves the stability and accuracy of the first digital signal while dividing the first digital signal into two paths. One path is connected to the sound and light alarm 121, and the first digital signal is directly connected to the sound and light alarm 121, which is used to directly alarm according to the water level information at the end of the water tank 27, thereby reminding the staff to conduct inspections. The other path is connected to the electric / optical converter 201, and the electric / optical converter 201 converts the first digital signal into an optical signal after processing. The electric / optical converter 201 is connected to the single-mode optical fiber, and the single-mode optical fiber is connected to the optical / electrical converter 41, through the single-mode optical fiber with a greater transmission distance. The electric / optical converter 201 and the optical / electrical converter 41 between the two sites are connected, the optical signal is transmitted to the electric / optical converter 201, and the second digital signal is output. The second isolator 1002 is connected to the output end of the optical / electrical converter 41 to enhance the stability and accuracy of the second digital signal. The second isolator 1002 is connected to the PLC to transmit the second digital signal to the PLC in the electrical control cabinet. The PLC is connected to the electric water pump 71, and is used to issue a work instruction to the electric water pump 71 according to the water level information carried in the second digital signal. When the water level information is lower than the preset range value, the electric water pump 71 is controlled to be turned on, and the water source in the reservoir 29 is dispatched to the water storage tank 27. When the water level information is higher than the preset range value, the electric water pump 71 is controlled to be turned off, and the dispatching behavior is stopped, thereby achieving the effect of driving the electric water pump 71 to automatically control the execution. Among them, the electric water pump 71 is also connected to the towing device 26, and the staff can also manually turn on and off the electric water pump 71 through the towing device 26. Through the conversion between the first digital signal, the optical signal and the second digital signal, the single-mode optical fiber can safely and stably transmit the water level information efficiently. In addition, the single-mode optical fiber has strong anti-interference ability and low price. It does not need to use network networking, effectively reducing production costs and is more suitable for areas such as Qinghai Salt Lake where the hardware of electrical equipment does not have Ethernet communication function.

[0060] Under the premise of realizing the safe and efficient transmission of water level information and focusing on controlling the insufficient coverage of 5G network and the high cost of purchasing and installing the industrial Ethernet architecture, a single-mode optical fiber is used to transmit water level information, and an armored single-mode 6-core optical fiber is laid along the water source pipeline 28, wherein armor refers to a layer of metal or non-metallic material wrapped around the outside of the single-mode optical fiber to enhance the tensile strength and wear resistance of the single-mode optical fiber. This method can protect the single-mode optical fiber from the influence of the external environment and extend the service life of the single-mode optical fiber. According to the production of the liquid level meter 102 in the fire water storage tank 27, the liquid level meter 102 displays and controls the output of the first digital signal, and the water level information is selected to be lower than the preset range value and higher than the preset range value as the control signal for starting or stopping the electric water pump 71 in the reservoir 29 to improve work efficiency.

[0061] The device provided by the embodiment has the following beneficial effects:

[0062] (1) In terms of cost, low cost control is achieved by adopting simple and low-cost single-mode optical fiber to replace the high-cost industrial Ethernet architecture and complex communication technology of 5G network communication.

[0063] (2) In terms of the installation process, armored single-mode optical fiber replaces complex networking and network configuration and other professional technologies, greatly reducing the difficulty of installation.

[0064] (3) In terms of performance, the long-distance information transmission controlled by single-mode optical fiber can meet the needs of remote information transmission and control between various electrical devices. The first isolator 1001 and the second isolator 1002 improve the stability and accuracy of the signal, effectively realize the signal anti-interference ability, and ensure the stable operation of the system and the accuracy of information transmission.
