Description

Technical Field

[0001] This invention belongs to the technical field of calcium carbide production monitoring equipment, specifically relating to an anti-lag transmission device for a calcium carbide furnace monitoring system. Background Technology

[0002] In the automated production process of calcium carbide furnaces, real-time monitoring of the operating status of on-site equipment is a core element to ensure continuous production, operational safety, and timely emergency response. The smoothness and stability of the monitoring screen directly affect the efficiency of production scheduling and fault prediction. Existing calcium carbide furnace monitoring systems generally adopt an on-site storage + network loop transmission mode. The video signals collected by the cameras need to be transmitted to the central control room through a long-distance network loop, and then forwarded to the monitoring computer in the central control center for display.

[0003] Traditional transmission methods have significant drawbacks: transmission distances typically exceed 500 meters, resulting in severe signal attenuation; 15-25 cameras need to be connected to the same loop, and multiple devices sharing bandwidth leads to frequent data conflicts and congestion, with the monitoring screen experiencing 1-2 pauses every 30 seconds, each lasting 2-5 seconds, and in severe cases, direct disconnection; simply upgrading routers or expanding bandwidth cannot solve the fundamental problems of long-distance loss and bandwidth contention, and will also increase hardware investment and maintenance costs, making it difficult to meet the high-reliability monitoring requirements of calcium carbide furnace production. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an anti-lag transmission device for a calcium carbide furnace monitoring system, characterized by uninterrupted transmission, zero signal loss, resistance to electromagnetic interference, long-distance stability, and low maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-lag transmission device for a calcium carbide furnace monitoring system, comprising an anti-lag transmission device body, wherein the anti-lag transmission device body includes a monitoring camera, a field-end photoelectric conversion module, an independent optical fiber, a terminal storage device, and a central control center monitoring computer, characterized in that multiple sets of monitoring cameras are arranged at the calcium carbide furnace site, and the terminal storage device is set in the engineer station computer room of the central control center; Each surveillance camera is equipped with a photoelectric conversion module, which is connected to the terminal storage device via an independent single-mode optical fiber. The terminal storage device is connected to the central control computer via a local area network to form a point-to-point independent transmission structure.

[0006] Furthermore, the surveillance cameras are industrial-grade high-definition cameras, and each surveillance camera's signal output terminal is independently connected to a set of photoelectric conversion modules.

[0007] Furthermore, the photoelectric conversion module includes a field-side photoelectric conversion module and a data center-side photoelectric conversion module. The field-side photoelectric conversion module converts electrical signals into optical signals, and the data center-side photoelectric conversion module converts optical signals back into electrical signals.

[0008] Furthermore, the independent optical fiber is a single-mode optical fiber with a core diameter of 9 / 125μm and a transmission distance of 500-2000 meters.

[0009] Furthermore, the independent optical fiber uses an LC interface to connect with the photoelectric conversion module, with a transmission attenuation of ≤0.5dB / 800 meters.

[0010] Furthermore, the terminal storage device was moved from the field control room to the engineer station computer room of the central control center, shortening the transmission path to the monitoring computer of the central control center.

[0011] Furthermore, the terminal storage device is directly connected to the central control center monitoring computer via a gigabit Ethernet cable.

[0012] Furthermore, each pair of surveillance camera signals shares an independent optical fiber to form a dual-path multiplexed point-to-point transmission structure.

[0013] Furthermore, the main body of the anti-lag transmission device has a transmission delay of ≤50ms and a data transmission success rate of ≥99.99%.

[0014] Furthermore, the anti-lag transmission device maintains smooth, uninterrupted video transmission even under the conditions of a calcium carbide furnace with high temperature and strong electromagnetic interference. Compared with the prior art, the beneficial effects of the present invention are: 1. This invention completely avoids data conflicts caused by multiple cameras sharing bandwidth by setting up a point-to-point independent optical fiber transmission structure, thus solving the problems of video lag, packet loss, and high latency at the source.

[0015] 2. This invention achieves the conversion and transmission of electrical signals and optical signals by setting up a photoelectric conversion module and a single-mode optical fiber, thereby reducing signal attenuation over long distances and improving transmission stability and anti-interference capabilities.

[0016] 3. By setting up a centralized storage structure in the central control center, the present invention moves the terminal storage device forward, shortens the transmission link, reduces the number of relay links, further reduces latency, and improves the real-time performance of the screen.

[0017] 4. By setting up a dual-path multiplexing transmission and industrial-grade adaptation structure, this invention reduces the cost of using optical fibers while ensuring smooth transmission, enabling the device to operate stably for a long time in the high-temperature and strong electromagnetic interference environment of a calcium carbide furnace.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 The present invention provides the following technical solution: an anti-lag transmission device for a calcium carbide furnace monitoring system, comprising an anti-lag transmission device body 1; the anti-lag transmission device body 1 includes a monitoring camera 11, a field-end photoelectric conversion module 121, a photoelectric conversion module 12, an independent optical fiber 13, a terminal storage device 14, and a central control center monitoring computer 15. Multiple sets of monitoring cameras 11 are arranged at the calcium carbide furnace site 16, and the terminal storage device 14 is located in the central control center engineer station computer room 17; each monitoring camera 11 is equipped with a photoelectric conversion module 12, and the photoelectric conversion module 12 is connected to the terminal storage device 14 through an independent single-mode optical fiber 13. The terminal storage device 14 is connected to the central control center monitoring computer 15 through a local area network to form a point-to-point independent transmission structure.

[0021] Furthermore, the monitoring camera 11 is an industrial-grade high-definition camera. The signal output terminal of each monitoring camera 11 is independently connected to a set of photoelectric conversion modules 12. By adopting the above technical solution, it is ensured that each video signal is transmitted independently and without interference, avoiding bandwidth contention and data conflicts caused by multiple devices sharing the link, and ensuring transmission stability from the signal source.

[0022] Furthermore, the photoelectric conversion module 12 of the present invention includes a field-end photoelectric conversion module 121 and a data center-end photoelectric conversion module 122. The field-end photoelectric conversion module 121 converts electrical signals into optical signals, and the data center-end photoelectric conversion module 122 restores optical signals to electrical signals. By adopting the above technical solution, the characteristics of low transmission loss and strong anti-interference ability of optical signals are utilized to achieve long-distance attenuation-free transmission, and completely solve the problems of traditional electrical signal transmission being susceptible to electromagnetic interference and having large signal attenuation.

[0023] Furthermore, the independent optical fiber 13 is a single-mode optical fiber with a core diameter of 9 / 125μm and a transmission distance of 500-2000 meters. By adopting the above technical solution, the actual transmission distance from the calcium carbide furnace site 16 to the control center engineer station room 17 is fully covered, meeting the long-distance signal transmission needs of large-scale factories, and maintaining extremely low signal loss even under long-distance transmission.

[0024] Furthermore, the independent optical fiber 13 uses an LC interface to connect with the photoelectric conversion module 12, with a transmission attenuation of ≤0.5dB / 800 meters. By adopting the above technical solution, the interface connection is compact, the transmission efficiency is high, and the loss is low, which can ensure that the signal is not distorted or interrupted during long-distance transmission, providing hardware support for smooth and clear monitoring images.

[0025] Furthermore, the terminal storage device 14 is moved from the field control room to the engineer station computer room 17 of the central control center, shortening the transmission path to the monitoring computer 15 of the central control center. By adopting the above technical solution, intermediate network forwarding links are reduced, data jump delay is reduced, and problems such as lag, packet loss, and excessive latency caused by long-distance network loops are avoided.

[0026] Furthermore, the terminal storage device 14 is directly connected to the central control center monitoring computer 15 via a gigabit Ethernet cable. By adopting the above technical solution, high-bandwidth, high-speed data transmission is achieved, ensuring real-time push and fast retrieval of high-definition video images, further reducing display latency and improving monitoring real-time performance.

[0027] Furthermore, in this invention, each pair of surveillance camera signals 11 shares an independent optical fiber 13 to form a dual-path multiplexed point-to-point transmission structure. By adopting the above technical solution, the utilization rate of optical fiber is improved while ensuring transmission quality, the number of optical fibers laid and construction costs are reduced, and the advantages of point-to-point transmission without conflict or lag are maintained.

[0028] Furthermore, the main body 1 of the anti-lag transmission device has a transmission delay of ≤50ms and a data transmission success rate of ≥99.99%. By adopting the above technical solution, near real-time synchronous transmission of images is achieved, ensuring that the display screen of the central control center monitoring computer 15 is highly consistent with the actual working conditions of the calcium carbide furnace site 16, thus meeting the low latency requirements for safe production monitoring.

[0029] Furthermore, the main body 1 of the anti-lag transmission device maintains a smooth, uninterrupted, and un-lag-free image even under the conditions of a calcium carbide furnace with high temperature and strong electromagnetic interference. By adopting the above technical solution, the single-mode optical fiber is not affected by the high temperature, dust, and strong electromagnetic environment of the factory area. The device has strong overall stability and can operate continuously and reliably for a long time in harsh industrial environments.

[0030] Working principle and usage process of the present invention: When in use, the monitoring camera 11 collects high-definition video signals from the calcium carbide furnace site 16 in real time, and transmits the electrical signals to the on-site photoelectric conversion module 121 to convert them into optical signals.

[0031] The optical signal is transmitted point-to-point to the engineer station computer room 17 of the central control center via independent optical fiber 13. After being converted back into an electrical signal by the photoelectric conversion module 122 at the computer room end, it is sent to the terminal storage device 14.

[0032] The terminal storage device 14 pushes video data to the central control monitoring computer 15 in real time via a gigabit Ethernet cable, achieving smooth, packet-free, and low-latency display of the video.

[0033] The device adopts a dual-path multiplexing transmission structure, which reduces costs while ensuring signal quality. It can also adapt to harsh working conditions such as high temperature and strong electromagnetic interference. The entire process does not require network loop forwarding, which fundamentally solves the problems of screen lag, interruption and high latency in traditional monitoring systems, and provides stable and reliable monitoring guarantee for the safe production of calcium carbide furnaces.
