radiation transmission mode. Therefore, from the disturbed sensors, the interference coupling can be divided into two kinds: conduction coupling and radiation coupling. The conduction transmission must have a complete circuit connection between the jamming source and the sensor, and the jamming signal is transmitted to the sensor through the connection circuit, and the interference phenomenon occurs. The transmission circuit may include a conductor, a conductive component of the equipment, a p

, armored layer to maintain connectivity. ② in accordance with the provisions of the ydj14-91, in the optical cable joints moisture-proof layer, armored layer and strengthen the core should be used for electrical disconnection, and are not grounded, the ground is insulated, can avoid the accumulation of inductive lightning in optical cables, It can also avoid the difference between the impedance of the lightning-proof line and the metal component of the cable to the ground circuit, which leads t

standard. Strict and thorough construction reflects meticulous professionalism The advantages of the shielded cabling system used in the project are mainly reflected in its strong ability to resist external electromagnetic interference and RF interference. It can also prevent the energy radiation from internal transmission signals to the outside world, provides good system security. However, the installation and grounding requirements of the shieldi

. 3) Vertical trunk Subsystem It connects communication rooms, equipment rooms, and entry devices, including trunk cables, intermediate switches and main switches, mechanical terminals, and connectors or plugs used for Trunk-to-trunk switches. The main wiring should adopt a star topology, And the grounding should comply with the requirements stipulated by EIA/TIA607. 4) Management Subsystem This part is placed in telecommunications cabling system equi

.(5) The input and output of the wire should try to avoid adjacent parallel. It is better to add line between the ground, in order to avoid the feedback coupling.(6) Digital and analog to separate, the low-frequency circuit, the ground should try to use a single point and join the ground, high-frequency circuit should be multi-point series grounding. For digital circuits, the ground should be closed to synthesize loops to improve noise resistance.(7)

values as needed. Sometimes it is marked with "*", indicating that it is determined by debugging.⑤ Used as the configuration circuit. This function is similar to patch cord or dial switch, but it is fixed by welding, so that common users can modify the configuration at will. By installing resistance at different positions, you can change the function or set the address of the circuit.0 euro resistance specifications, generally divided by power, such as 1/8 Watts, 1/4 Watts and so on.1. Single P

the top layer of a dual-Panel designed for automatic cabling. The underlying layer 2 of this double panel shows the circuit schematic 3A and Figure 3b of these cabling layers. When designing this hybrid signal circuit board, the device is manually placed on the board to separate the numbers from the simulator.When using this wiring scheme, you need to pay attention to several aspects, but the most troublesome thing is grounding. If the ground wire is

They determine the number of devices in the Power Distribution Device and indicate how to connect generators, transformers, and lines, and how to connect to the system to complete the transmission and distribution task.9. Current Transformer: The instrument converter is an instrument that converts large current into small current.10. Transformer: a static electrical device used to change the AC voltage of a certain value to another type or multiple types of AC voltage with the same freq

Materials: VGA adapter pair (buy the corresponding male or female head for your device); A wire that is cut according to your actual distance; Tools: iron; scissors; stripping pliers; soldering iron; scissors; stripping pliers; such; Method: 1. First of all to peel off the network line, finishing 8 core 2 to 8 cores to peel off a centimeter of insulation batch skin 3 Next is the welding, the cable and VGA head are welded by the connection diagram below. 4 attached VGA each PIN definitio

protection of the shell requires you to be more careful, to avoid the sharp object and the shell contact. If there is a condition, give it a soft inner bag, which can avoid the damage of the shell to some extent. Said the shell, can not say that the laptop's wrist part, which is the most commonly used in the body to contact the part of the wrist will be in the work of the machine generated by the heat and sweat, long time will be caused by the corrosion of the wrist coating. Fortunately, many

August 2018, the Netherlands Xsens company released the latest version of the MVN software: version 2018.2 mvn software and SDK, added to the Netherlands Manus VR virtual reality glove (Manus VR gloves) support. Xsens version Manus virtual reality glove is the Netherlands Xsens Company and the Netherlands Manus VR company launched the virtual reality glove, the product will be exhibiting 2018 Canada SIGGRAPH exhibition.Why is Manus VR chosen as the head of the first place to capture the inertial

at the beginning of Samsung. Later Sony started to follow up, but their functions were still relatively simple, it needs to be used with smart phones, such as answering calls, receiving push messages from social networking websites, reading text messages, and alarm alarms. The functions are quite limited, and they are similar to chicken ribs, there are still many problems with the product. In the future, the second-generation products will begin to improve the performance. Currently, Amazon has

The pitfalls for sending broadcast packets through Android SocketThe Socket broadcast package is often used for mutual discovery and message transmission between two devices in the LAN. During Android Application Development, such requirements are often met. For example: between Two Android devices, smart hardware such as Android and wristband, and between Android and Windows. This article mainly introduces the programming precautions when using Socke

Seven, electrostatic problem Electrostatic is an important factor affecting ADSL, and the power supply in the home is generally not the grounding line, coupled with a variety of electrical appliances (such as refrigerators, television) interference, it is easy to cause electrostatic interference, resulting in the ADSL in the use of frequent drop line, please the three-core socket

shielding systems, such as a serious electromagnetic interference in the environment of users, such as factories, radio stations, radio, airports and subways, the other is for security considerations, strict requirements of the confidential units, such as national defense, Government, finance At present, the shielding system has become more and more the user's choice. However, it should be emphasized that for the shielding system, a single layer of metal shielding is not enough, more importantl

Scheduler AllocateEndDiagnostics process The author carefully examines the configuration file and finds that the IP pool is missing, plus the IP local pool lab (start IP addr) (stop IP addr) has no effect. Later, the author thought of the use of dial-up analog signals, and grounding has a great relationship. No automatic response: Most of the grounding problem. So directly to the router

EMI filter circuit, in order to filter out the power grid high-frequency pulse interference, but also to filter the power itself to the external production. 220V AC, through the FireWire and 0-line input to the computer power of the EMI filter circuit, the connecting point between the capacitance is connected with the shell of the power supply, and the shell of the computer power supply is connected with the grounding wire, when there is no

caused by the failure of the post, some technicians are advised to use a separate socket. Also some netizens believe that the "big cat" power quality is generally bad, anti-interference ability is particularly poor, especially for a long time to use a severe fever, resulting in equipment failure. Therefore, it is recommended to switch to high-quality power supply (only the price is more expensive). 3, the equipment (including the host) for good shielding and
