Video surveillance transmission network construction core technology of optical fiber transmission
The information transmission in the digital era is so efficient that part of it benefits from the rapid development of optical fiber communication technology. Optical fiber was originally born as a medical endoscope. Because of the limited technology at the time, the transmission attenuation of light in the optical fiber was very large, so researchers at that time did not favor the application of optical fiber in communication. Later, after the British Chinese scholar Takashi Takashi's...
Security Tips: Fiber Transmission Rate and Corresponding Transmission Distance
In daily life, optical fiber is used as a long-distance information transmission because the conduction loss of light on the optical fiber is much lower than the loss of electricity conduction on the electric wire. In general, the terms optical fiber and optical fiber cable will be confused. Most optical fibers must be covered by several layers of protective structures before use. The covered cables are called optical cables. The outer protective structure of optical fibers prevents the...
Optical fiber transmission system structure and transmission characteristics
Due to the nature of the wire, the coaxial cable has a limited transmission distance. In the environment where the electromagnetic wave is used, the electromagnetic wave interference reduces the transmission efficiency of the coaxial cable. If the installation site is located in a multi-relief area, the equipment at both ends It will be damaged by lightning strikes. Optical fiber transmission has the advantages that coaxial cables cannot match and becomes the preferred device for long-distance...
Automatic transmission solenoid valve inspection method
The automatic transmission solenoid valve is like a faucet. Different hydraulic fluid flows through different opening degrees, and different pressures are generated. The solenoid valve is controlled by the transmission electronic control module TCU. Basically, the neutral pressure and the pressure in the gear are constant values. The solenoid valve opening is adjusted during shifting to improve shift smoothness. Different solenoid valves control different clutches or brakes and function in...
Automatic transmission solenoid valve is monopolized by foreign capital
At present, there are almost no domestic companies that can professionally produce hydraulic valve bodies and solenoid valves for automotive automatic transmissions. The automatic transmission is the core component of an automatic car. The solenoid valve and the hydraulic valve body are both the core components of the automatic transmission of the automobile and the key basic components of the construction machinery, agricultural machinery and machine tool industries, and have large demand. On...
Application of Gigabit Ethernet Media Converter in LED Display Transmission System
1 Introduction The LED display is a new type of flat panel display device that appeared in the 1990s. It is popular because of its high brightness, clear picture and bright colors. The full-color LED display utilizes the principle of three primary colors to produce a color effect by superimposing three kinds of LEDs of red, green and blue; the true color LED display has 8-bit gray value for each single primary color, that is, the single pixel is composed of 24-bit RGB binary. The number...
In-depth analysis of pneumatic transmission, hydraulic transmission and hydraulic transmission
First, the pneumatic transmission articles Pneumatic transmission uses compressed gas as the working medium, and the fluid transmission of power or information by the pressure of the gas. The system that transmits power is to transfer compressed gas to the pneumatic actuator through the pipeline and control valve, and convert the pressure energy of the compressed gas into mechanical energy to work; the system that transmits information uses the pneumatic logic component or the fluidic component...

The original prototype of the Centennial transmission system giant ZF AMT transmission - Soden transmission
In 1921 ZF developed a transmission called Soden, named after his inventor von Soden (the co-founder and first general manager of ZF). The Soden transmission is a four-speed transmission with a constant meshing gear design and a pre-selected gear and synchronizer. The transmission is designed with a pre-selected mechanism that allows the driver to decide in advance which gear to be engaged.
