The integrated wiring system is like the nerves in the building. It uses a series of high-quality standard materials and integrates voice, data, images and some control signal systems with a unified transmission medium through a modular combination. Planning and design, integrated in a standard wiring system, organically connects the three major subsystems of modern architecture, and provides the physical medium for the system integration of modern architecture. It can be said that the success of the structured cabling system is directly related to the success of the modern building, and it is crucial to choose a high quality integrated cabling system.
What are the "general cabling" in weak current projects?
router
Also known as a gateway device, it is used to connect multiple logically separated networks. The so-called logical network represents a single network or a subnet. When data is transmitted from one subnet to another, it can be done through the routing function of the router. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish a flexible connection in a multi-network interconnection environment, and can use different data packet and media access methods to connect various subnets. The router only accepts the source station or The information of other routers is an interconnected device at the network layer.
switch
A network device for relaying electrical signals. It can provide exclusive access to electrical signals for any two network nodes in the access switch. The most common switch is an Ethernet switch. Other common telephone and voice switches, fiber switches and so on.
Fiber Transceiver
An Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electric signals and long-distance optical signals is also called a photoelectric converter in many places. The products are generally applied in the actual network environment where the Ethernet cable cannot cover and must use optical fiber to extend the transmission distance, and are usually located at the access layer application of the broadband metropolitan area network. At the same time, they help connect the last mile of the optical fiber to the metropolitan area. The network and the outer network have also played a huge role.
optical fiber
The abbreviated optical fiber is a fiber made of glass or plastic that can be used as a light-conducting tool. The transmission principle is 'total reflection of light'. Former President of the Chinese University of Hong Kong and Gao Ao and George A. Hockham first proposed the idea that optical fiber could be used for communication transmission. Gao Hao won the 2009 Nobel Prize in physics.
Optical cable
Manufactured to meet optical, mechanical, or environmental performance specifications, it is a communications cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Fiber optic cable is mainly composed of optical fiber (fine as the glass fiber of hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical fiber cable, generally no recovery value. Fiber optic cable is a certain number of optical fibers in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer sheath, to achieve a kind of optical signal transmission line. That is, the cable formed by the optical fiber (optical transmission carrier) after a certain process. The basic structure of the optical cable is generally composed of cable cores, reinforcing steel wires, fillers, and jackets. In addition, components such as a waterproof layer, a buffer layer, and an insulated metal wire are also provided as required.
Patch panel
The purpose is mainly modular equipment for managing front-end information points at the central office. The front-end information point cable (Category 5 or Category 6) enters the distribution frame after entering the equipment, and the cable is placed on the module of the distribution frame. Then, the jumper (RJ45 interface) is used to connect the distribution frame and the switch. . In general, the patch panel is used to manage the equipment. For example, if there is no patch panel, the front-end information point is directly connected to the switch, and if there is a problem with the cable, it will face rewiring.
ups
The uninterruptible power supply is a system device that connects a battery (mainly maintenance-free lead-acid battery) to a host computer and converts DC power into commercial power through a module circuit such as a host inverter. It is mainly used to provide a stable, uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the mains input is normal, the UPS will supply the utility voltage to the load after use. At this time, the UPS is an AC mains voltage regulator. At the same time, it will also charge the internal battery; when the utility power is interrupted (accidental power failure) At the time, the UPS will immediately supply 220V AC power to the load by switching the DC power of the battery to the load through the inverter zero switching method, so that the load can maintain normal operation and protect the load software and hardware from being damaged. UPS equipment is usually protected against overvoltage or undervoltage.
server
Computers that manage resources and provide services to users are usually divided into file servers, database servers, and application servers. The computer or computer system running the above software is also referred to as a server. Compared with ordinary PCs, servers have higher requirements in terms of stability, security, and performance. Therefore, CPUs, chipsets, memory, disk systems, and networks are different from ordinary PCs.
Network panel
Refers to a type of cabling product that is applied to the work area wiring subsystem and is suitable for multi-type module installation. Its main function is to fix the module and protect the cable at the exit of the information and play a role similar to the screen. The network panel is not the main product component that affects the performance of the cabling system. However, in the entire cabling system, it is one of the few products exposed on the wall surface. Its performance and aesthetics directly affect the overall cabling. Effect.
The development of the automotive industry is ephemeral in an unpredictable direction, but whether it is from steam engines to fuel engines to electric vehicles, safety and high speed are the direction pursued by car manufacturers all over the world. The stable output of power is inseparable from the engine or motor. Working at suitable temperatures, water radiators and Intercooler and motor cold plate heat exchanger are all areas of design and production that we are good at. The water radiators we produce can be divided into two structures, plate-fin structure and tube fin structure. The most professional radiators are customized according to the customer's engine parameters, and the intercooler for high pressure and high temperature is designed according to the turbocharged engine design.
