Patent Interpretation There is even an anti-rat optical fiber, which is really eye-opening
According to the latest announcement of the National Patent Office, Zhongtian Technology has invented a hybrid optical cable that can prevent freezing and mice, which is really eye-opening; We all know that optical fiber is used to transmit optical signals, and it is difficult to connect with mice, and this time through the analysis of this patent is also a long insight, distributed in remote areas such as mountainous areas, the power distribution system, due to the serious rodent infestation, the optical cable is often bitten by rodents, which brings great difficulties to the maintenance of the line.
There should be many ways to prevent rats from eating, and human beings have accumulated a lot of experience in the fight against rats for thousands of years, why can new inventions be made on optical fibers? The existing rodent-proof cable mostly adopts chemical and physical rodent-proof methods, and the chemical rodent-proof cable casing adopts the rodent-repellent drug to protect the optical cable, but this is not conducive to the balance of the local ecosystem, causes pollution, and the rodent-proof effect is not ideal. At present, the physical rodent prevention method mostly uses the metal armor layer to prevent rats, but this method can not effectively resist the invasion of mice, and at the same time, it will lead to the shortcomings of excessive cable weight and unsafe in outdoor lightning weather. The damage of the cable by rats may cause leakage, short circuit, communication interruption, and even lead to fire, which poses a threat to people's lives and health. At the same time, because the rodent-proof cable is mostly used outdoors, it is also necessary to take into account the impact of low temperature, high temperature, fire and other weather conditions on the communication transmission capacity, so it is urgent to explore a new type of rodent-proof cable.
Patent Analysis:
The anti-rat function is mainly completed by the anti-rat structure in the optical cable at the position 4 in the figure below, and the main content in the structure 4 is the anti-rat chip + wire, which is the most critical module to realize the anti-rat; The approximate working principle is as follows: the cable core includes an optical unit and an electrical unit to realize the integrated mixed transmission of photoelectric integration, when the photoelectric hybrid cable body is connected to the external wire, it will also provide power to the wire connected to the anti-rat chip, the anti-rat chip integrates an infrared detector, a controller and a buzzer, the infrared detector sends the induction signal to the controller, the controller sends instructions to the buzzer, and the buzzer emits a mouse-repellent sound wave, so as to realize the ultrasonic wave after sensing the mouse to approach to achieve the purpose of anti-rat. The infrared ultrasonic anti-rodent structure can emit rat-repellent sound waves, which is safer and more environmentally friendly than chemical anti-rodent. At the same time, the infrared ultrasonic anti-rodent structure is embedded in the tape layer to form a whole with the optical cable, which optimizes the product structure, simplifies the production process, reduces the product cost, and avoids the possibility of the anti-rat structure being damaged in the external environment. The optical cable contains a low-temperature resistance wire, which can heat up at low temperatures and play a cold-resistant and anti-freezing role; The flame-retardant film coated on the outermost side of the cable is not only difficult to burn, but also reduces the health and environmental problems caused by the high amount of smoke generated during combustion.
An object of the present invention is to provide an anti-freeze fire-resistant sound stimulation anti-rat photoelectric hybrid cable to solve the technical problem that the anti-rat cable is not safe and environmentally friendly enough in the prior art.
