Description

Technical Field

[0001] The utility model relates to the technical field of equipment communication, in particular to an on-site optical fiber communication unit and a melting point condition tester. Background Art

[0002] During the construction process, multiple departments need to work together. At present, walkie-talkies or mobile phones are used to complete communication on site. However, the diverse building structures on site have a great impact on wireless signals. The communication support conditions during construction are not good, and walkie-talkies or mobile phones cannot meet the use needs. The span of modern communication networks is very large, which has greatly exceeded the intercom range of general walkie-talkies. The basis of modern communication networks is generally optical fiber networks, which are characterized by long distances and many jump nodes. When the receiving parties are not together, many tasks are done simultaneously. Only using language communication is inefficient and unstable at the construction site. If there are more channels to support communication, the collaborative efficiency will be improved accordingly.

[0003] However, when using optical fiber for communication, there is a certain sensitivity to the attenuation during the transmission process. If the attenuation becomes much larger, the transmission level will change, which can be felt during communication, thus discovering that the optical fiber attenuation is abnormal and indirectly discovering the problem. For this reason, we propose an on-site optical fiber communication unit and melting point tester. Utility Model Content

[0004] The utility model aims to provide an on-site optical fiber communication unit and a melting point tester to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an on-site optical fiber communication unit and a melting point tester, comprising a receiving end tester, a sending end tester and an optical fiber body, one side of the receiving end tester and the sending end tester are provided with an optical fiber interface, and the optical fiber interfaces of the receiving end tester and the sending end tester are connected through the optical fiber body;

[0006] The receiving end tester and the sending end tester both include a PCB board, the input end of the PCB board is electrically connected to a multi-channel bidirectional optical fiber audio device, the multi-channel bidirectional optical fiber audio device is connected to an optical fiber body, the output end of the PCB board is electrically connected to a carbon crystal microphone and an external speaker, and the other output end of the PCB board is electrically connected to a wireless unit and an antenna unit connected to an external Bluetooth device;

[0007] It also includes a standard signal generator, which is used to emit a sinusoidal slope of a specific frequency F to determine the quality of the optical fiber body.

[0008] Furthermore, a power indicator light and a signal strength indicator light are provided on the surface of the wireless unit and the antenna unit, and the power indicator light and the signal strength indicator light are electrically connected to the PCB board. A battery is provided inside the receiving end tester, and the output end of the battery is electrically connected to the input end of the PCB board. A power interface for charging the PCB board is provided on the back of the receiving end tester.

[0009] Furthermore, a placement mechanism for suspending the entire device is provided on the top of the receiving end tester, and a fiber optic positioning mechanism for preventing the fiber optic body from being bent and damaged is fixedly connected to one side of the receiving end tester and at the position corresponding to the fiber optic interface.

[0010] Furthermore, the placement mechanism includes a positioning tube, a telescopic tube and a pulling rope. A threaded groove is opened on the top of the receiving end tester, and a positioning tube is fixedly installed on the bottom of the inner wall of the threaded groove. The inside of the positioning tube is slidably connected with the telescopic tube. The top of the telescopic tube is fixedly connected to a threaded rod threadedly connected to the threaded groove through a pulling rope, and the top of the threaded rod is fixedly connected to a suspension ring through a sealing plate.

[0011] Furthermore, the optical fiber positioning mechanism includes a support rod, a limit tube and a guide block. A support rod is fixedly connected to one side of the receiving end tester and located below the optical fiber interface. The top of the support rod is fixedly connected to the limit tube. One end of the limit tube is fixedly connected to an arc-shaped guide block. The top of the limit tube and the guide block are provided with placement grooves for convenient placement of the optical fiber body.

[0012] Furthermore, the materials used to make the position-limiting tube and the guide block are both elastic materials, and a plurality of groups of adsorption magnets are fixedly connected to the back of the receiving-end tester.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model can detect the optical fiber body by setting a receiving end tester and a sending end tester, and the receiving end tester and the sending end tester are composed of a multi-channel bidirectional optical fiber audio device, a PCB board and a carbon crystal microphone, which can complete full-duplex voice communication, and then the selected signal generation and indication unit can be used to complete the bidirectional state indication, and under the pre-agreed coding, the selected state is written into the intercommunication; a specific level indication circuit is used to measure the communication level, so as to indirectly measure the attenuation of the optical fiber body;

[0014] The standard signal generator is set to emit a sinusoidal slope of a specific frequency F. The frequency and size are given. After the structure of the optical fiber body changes, the transmission attenuation and transmission linearity will definitely change. The attenuation surface is when the signal level strength changes at the receiving end. Poor transmission linearity will be reflected in the change of the signal frequency component sinusoidal slope. These two changes provide us with the possibility of indirectly discovering a major fault in the optical fiber body. The tester at the receiving end uses a frequency selection circuit to select the frequency. If the abnormal appearance of the second harmonic is found, it can be determined as a fault in the optical fiber body. If the size of the sinusoidal slope of the frequency F shows abnormal attenuation, it can also be determined that the optical fiber body has a fault, so that a communication channel can be quickly established to provide reliable communication conditions for the test work.

When there are iron materials nearby, it can be placed by adsorption magnets, which is convenient for placement. The optical fiber positioning mechanism can support the optical fiber body after the optical fiber body is connected to the optical fiber interface to prevent the optical fiber body from being bent and damaged when the entire device is taken.
