Description

Technical Field

[0001] The invention relates to the technical field of communication maintenance and repair tools, and in particular to a detection device using a multi-channel red light source. Background Art

[0002] Red light source is a visible light source, usually used for fiber identification, single-mode or multi-mode fiber fault location and fiber identification. It is a powerful supplement to OTDR test blind spots and a basic tool for maintaining fiber optic networks, LANs, ATM fiber optic systems and telecommunication network systems.

[0003] The central wavelength of the red light source is 650nm. It has a large attenuation when transmitted in the optical fiber. That is, after the red light is injected into the optical fiber, the entire optical fiber appears red from the outside, and a clear red light can be seen at the output end. If the optical fiber is broken, the red light at the breakpoint is obviously stronger than other places or the red light at the output end is darker. Therefore, the red light source is usually used for short-distance optical fiber visual fault inspection.

[0004] At present, the traditional red light source adopts a single measurement port, that is, it can only measure one optical fiber at a time, which is difficult to adapt to the rapid positioning of multi-core optical cables and batch optical cables. The traditional red light source fault positioning relies on visual inspection, which requires the operator to have rich experience. If the optical fiber attenuation needs to be further determined, the red light source optical power measurement device needs to be connected, which is not very convenient to operate. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a multi-channel red light source, which mainly integrates N red light source modules and one red light power measurement module, and can simultaneously detect whether there are breakpoints in N optical fibers. The optical fiber attenuation is further measured by the integrated red light power meter, which solves the problem that it is difficult to adapt to the rapid positioning of multi-core optical cables and batch optical cables.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the present invention proposes: a multi-channel red light source, composed of an ARM embedded module, a red light power monitoring module, an N-way red light source module, a liquid crystal display module, and a power management module, wherein the ARM embedded module is respectively communicated with the N-way red light source module, the liquid crystal display module, and the red light power monitoring module, and the power management module is respectively electrically connected with the ARM embedded module, the red light power monitoring module, the N-way red light source module, and the liquid crystal display module;

[0028] Among them, the ARM embedded module sends the red light line information that the user needs to measure to the N-channel red light source module. The N-channel red light source module emits red light and injects the red light into the optical fiber. The entire optical fiber appears red from the outside. If the far end sees obvious red or the other end uses a red light power meter and the red is broken or much darker, it means that there is a problem with the optical fiber at that point, completing the diagnosis of the optical fiber line;

[0029] The red light power monitoring module measures the red light power of a certain optical fiber and transmits the measured data to the ARM embedded module. After the CPU of the ARM embedded module processes and analyzes the data, it transmits the measurement results to the LCD display module for display and presents them to the user. The user completes the human-computer interaction through the LCD display and the capacitive touch screen.

[0030] The ARM embedded module controls the operation of the lasers of the N-channel red light source modules according to the set user parameters, connects the red light power monitoring module to the corresponding optical cable link, and completes the corresponding link measurement;

[0031] The power management module supplies power to the ARM embedded module, the red light power measurement module, the N-channel red light source module and the LCD display module;

[0032] The N-channel red light source module and the red light power monitoring module are combined together to facilitate the detection of multiple optical fiber lines during use. Multiple optical fiber measurements can be completed at one time to diagnose whether the optical fiber line is damaged. At the same time, red light power detection can also be performed on one of the optical fiber lines to measure the optical fiber attenuation, so as to better understand the specific conditions of the optical fiber line and perform fault diagnosis.

[0033] Among them, the LCD display module is a seven-inch LCD display, and a capacitive touch screen is installed on the LCD display, which is convenient for setting and modifying parameters of the entire device directly by touching it with your hands during use, and completing the input of measurement instructions. The input instructions are processed by the ARM embedded module and transmitted to the red light power monitoring module and the N-channel red light source module to measure the optical fiber line and present the measured data for users to view in time.

[0034] Among them, the ARM embedded module, the red light power monitoring module, the N-way red light source module, the liquid crystal display module and the power management module are all integrated in the same housing. The N-way red light source module is a red light source VFL, which is a visible laser light source. It uses a 650nm laser as a light-emitting device and is an ideal tool for testing various types of optical fiber jumpers, pigtails, and maintenance of construction sites or optical fiber lines. It has a low-battery alarm circuit to notify the user to replace the battery before the battery energy is about to run out; a special laser drive circuit is used to ensure that the laser has a constant power output above the minimum allowable battery power; stable wavelength output, small size, light weight, easy to carry, simple interface, easy to operate, and completes the detection and optimization of mechanical connection points; an optical fiber connection port is provided on the housing, and the ARM embedded module is connected to the N-way red light source module through the GPMC bus, the ARM embedded module is connected to the power detection module through the UART serial port, and the ARM embedded module is connected to the liquid crystal display through the RGB bus, which is convenient for the user to realize the stable transmission of data between the modules during use, so as to achieve the purpose of stable use.

[0035] Among them, the N-channel red light source module includes ADC, FPGA and laser. The laser and red light power monitoring module are connected to the optical fiber connection port set on the outer shell. The laser is used to emit red light for detecting the optical fiber line. The optical fiber connection port is used to stably connect the optical fiber end to be detected to the equipment to ensure stable completion of the detection operation.

[0036] like Figure 3 , Figure 4 and Figure 5As shown, in the detection device using the multi-channel red light source, an anti-dropout component 1 is arranged at the optical fiber connection port position set on the detection device shell, and the anti-dropout component 1 includes a placement seat 101 fixedly embedded at the optical fiber connection port position, so that the entire anti-dropout component 1 can be stably installed at the optical fiber connection port position, and the two can be used in conjunction with each other to achieve stable and effective optical fiber connection operation, and prevent the optical fiber from loosening and falling off from the optical fiber connection port. The resistance ring 103 slidably arranged in the placement seat 101 is placed on the upper end of the support spring 102, and the support spring 102 is used to provide a push for the resistance ring 103 The force makes the resistance ring 103 exert an effective resistance to the anti-dropping clamp 1011. At the same time, when the resistance ring 103 moves downward, the support spring 102 is synchronously compressed. Then the downward force is withdrawn, and the support spring 102 pushes the resistance ring 103 to reset. The resistance ring 103 is sleeved on the anti-dropping clamp 1011 provided on the mounting seat 101, and the optical fiber is stably and effectively clamped and fixed. A limiting ring plate 104 is provided at the upper port position of the mounting seat 101 to prevent the resistance ring 103 from sliding off the mounting seat 101, thereby ensuring stable use.

[0037] The connecting ring plate 1041 integrally arranged at the lower part of the limiting ring plate 104 is threadedly connected to the inner wall at the upper port position of the mounting seat 101, and the resistance ring 103 is slidably connected to the through-hole opened on the limiting ring plate 104. The limiting ring plate 104 is stably installed at the port position on the upper part of the mounting seat 101 to effectively block the resistance ring 103 and prevent the resistance ring 103 from sliding off the mounting seat 101, so that the two can be stably used together, and the lower end of the resistance ring 103 is integrally provided with a lip plate 1031, and the edge of the lip plate 1031 slides and resists on the inner wall of the mounting seat 101, so as to improve the sliding stability of the resistance ring 103 in the mounting seat 101 and ensure stability The lip plate 1031 is provided with an annular recessed groove 1033 at the position corresponding to the upper end of the support spring 102, and the upper end of the support spring 102 is placed in the annular recessed groove 1033, so that the support spring 102 is stably placed on the resistance ring 103, and effective supporting force is provided for the resistance ring 103, so that the resistance ring 103 can effectively push the anti-dropping splint 1011, and the upper end of the resistance ring 103 is integrally provided with a pushing ring plate 1032, so that the user can directly press it with his hand, thereby effectively driving the resistance ring 103. In the initial state, the resistance ring 103 is located at the uppermost end of the anti-dropping splint 1011, and the inner diameter of the annular structure formed by the combination of the anti-dropping splint 1011 is the smallest.

[0038] The anti-slip clamps 1011 are distributed in a circular array on the mounting seat 101, and a clamp that clamps the outside of the optical fiber is formed in the mounting seat 101 to clamp and fix the optical fiber, and effectively limit and fix it to prevent the optical fiber from loosening and falling off due to external forces, so as to achieve the purpose of stable connection. The gaps between the anti-slip clamps 1011 form deformation grooves 1013, which are convenient for the anti-slip clamps 1011 to deform under the resistance of the resistance ring 103, and push the upper ends of the anti-slip clamps 1011 toward the central axis position of the mounting seat 101, so as to achieve the purpose of effectively clamping and fixing the optical fiber. When the resistance push on the anti-slip clamps 1011 is cancelled, the anti-slip clamps 1011 are reset, and the anti-slip clamps 1011 are withdrawn. The pin limits the position of the optical fiber, and the optical fiber can be pulled out and removed afterwards. The inner wall of the anti-slip clamp 1011 is integrally provided with anti-slip teeth 1012 distributed at equal intervals, which is convenient for enhancing the effect of limiting and fixing the optical fiber and improving the stability of clamping and fixing. The outer wall of the upper end of the anti-slip clamp 1011 forms an inverted interference slope, and the inner wall of the interference ring 103 is set as a pushing slope that fits the interference slope. The slopes between the two cooperate with each other and interfere with each other. When the interference ring 103 slides upward, an inward pushing force is applied to the upper end of the anti-slip clamp 1011, so that all the anti-slip clamps 1011 move toward the inside, and the optical fiber is effectively clamped and fixed.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
