Millet hand Ring has almost all the basic functions of the intelligent hand ring, in addition to the steps, sleep monitoring, but also provides the answer to the reminders, shaking wake and other functions. By adapting to the Millet mobile phone (or MIUI system), the bracelet also provides a unique "hand ring unlocking" function. As for the lack of time to display the function, this is indeed a pity, but considering the cost, this is also helpless. D

not be too many to avoid tangle of multiple cables on the ground. 3. After the wire pulling process ends, the redundant cables at both ends should be organized and protected. When the wire is laid, the original rotation direction should be followed. The diameter of the coil should not be too small, if possible, use the waste wire head to be fixed on the bridge, ceiling or in the carton. Make a note to remind other personnel not to step on. 4.

Cables and metal pipes outside the building should be grounded before entering the building. lightning arresters should be added at the entrance when the cables and metal pipes outside the building are
) ensure that the probe grounding is as short as possible (the main reason for measuring the ripple is that the grounding line is too long). Try to use the original test short needle that comes with the probe. If no short needle is tested, the grounding wire and shell of the probe can be removed to expose the probe's crust. The self-made

good confidentiality. The shielding structure of Shielded Cables has inherent advantages in reducing mutual interference between cables, it not only shields external electromagnetic signals, but also blocks the electromagnetic leakage of cables. It does not emit interference signals, affecting other cables and preventing information from being eavesdropped. In the shielded network cable, there will be a copper wire, that is, the ground line, you can use a shielded RJ45 socket, when used, line a
Unlike office and home Ethernet, which has long been well known, industrial Ethernet requires more professional knowledge and practical experience. If you are installing or using an industrial Ethernet, you must understand the Five Points of cabling, signal quality, grounding circuit, switch, and communication. Wiring problems Like all networks, the advantages and disadvantages of cables directly affect the advantages and disadvantages of Industrial E
To measure the modernization standard of urban buildings, the design form and intelligence of buildings are two main aspects. The Weak Current System of Intelligent Building mainly consists of the following systems: (1) communication network system;(2) Office Automation System;(3) construction equipment monitoring system;(4) automatic fire alarm and linkage control system;(5) Public security defense system;(6) Structured Cabling System;(7) Weak Current Power Supply and
cord (VCC) and the ground wire.• The lead length of the capacitor should not be too long, especially the high-frequency bypass capacitor should not contain the lead. (3) In the single-chip microcomputer control system, there are many types of ground wires, such as systematic, shielded, logical, and analog ground. Whether the ground wires are properly laid determines the anti-interference capability of the circuit board. When designing ground and ground points, consider the following:• Logically
should be as bold as possible, and the grounding area of the lead end should be increased as much as possible. Generally, input and output SimulationSignal , It is best to isolate from single-chip microcomputer circuit through optical coupling. When designing a printed circuit, the ground line should form a closed loop to improve the anti-interference ability of the circuit. The ground line should be as rough as possible. If the ground line is very f

Industrial Ethernet cabling and fault Maintenance The industrial environment is worse than the general environment. At least the vibration, moisture, and temperature are worse than the general environment. Industrial Ethernet requires more professional knowledge and practical experience.
