Description
Technical field
The present invention relates to a kind of Computer signal data cable, a kind of trusted computer count with fire-proof function
According to cable and preparation method thereof.
Background technology
Wires and cables industry product category is numerous, and range of application is quite varied, relates to electric power, petrochemical industry, communicates, makes
The industry such as make, the most closely related with each department of national economy.RS cable is referred to as " tremulous pulse " and " neural " of national economy,
It is transmission information and various signal, it is achieved electromagnetic energy changes indispensable basic equipment, is Future Information society
Basic product necessary in Hui.Especially fast development Chinese Home as China, capital construction and auxiliary facility construction
Huge demand is self-evident.
Data transmission between computer and computer or computer and terminal can use serial communication and parallel communication
Two kinds of modes.Owing to serial communication mode has use, circuit is few, low cost, particularly when remote transmission, it is to avoid a plurality of
Line characteristic inconsistent and be widely adopted.When serial communication, it is desirable to communication two party all uses a standard interface, makes not
Same equipment can couple together easily and carry out communication.The RS-232 interface of early application also exists more deficiency, for
These are not enough, the most constantly occur in that some new interface standards, RS-485 are exactly one of them.
Refer to Fig. 1, at present conventional a kind of RS-485 Computer signal data cable, including three cable inner cores 1, with
And three outer internal shield 2, external shielding layer 3 and sheaths 4 being coated with successively of cable inner core 1；Three cable inner cores 1 set symmetrically
Putting, each cable inner core 1 all includes two conductor cores groups 11 within lapping layer 13, lapping layer 13, and each conductor cores group
The insulating barrier 12 of 11 outer claddings；And each conductor cores group 11 is made up of several conductor strand respectively.General conductor is tin plating copper core；
Insulating barrier 12 and lapping layer 13 use high density polyethylene (HDPE) foaming or foam fluoroethylene-propylene material to make；Internal shield 2 uses
Aluminium moulding material is composited；External shielding layer 3 uses tinned copper wire braiding to form；Sheath 4 uses polrvinyl chloride or foam fluorine
Ethylene propylene material is made.
This RS-485 Computer signal data cable has the following characteristics that
(1) electrical characteristic of RS-485: logical one represents with the voltage difference of line-to-line for+(2-6) V；Logical zero is with two
Voltage difference between line is that one (2-6) V represents.Interface signal level reduces than RS-232, is just hardly damaged the core of interface circuit
Sheet, and this level is compatible with Transistor-Transistor Logic level, can facilitate and be connected with TTL circuit；
(2) the data maximum transmission rate of RS-485 is lOMbps；
(3) RS-485 interface is to use balance driver and the combination of differential receiver, and anti-common mode disturbances ability strengthens, i.e.
Noise immunity is good；
(4) the maximum transmission distance standard value of RS-485 interface is 4000 feet, actually up to 3000 meters, and additionally RS-
232 interfaces only allow to connect 1 transceiver, i.e. single station ability in bus.And RS-485 interface is to allow to connect in bus
Up to 128 transceivers.I.e. having multistation ability, such user can utilize single RS-485 interface to set up easily and set
Standby network；
There is the above-mentioned advantages such as good noise immunity, long transmission range and multistation ability because of RS-485 interface,
Become the serial line interface of first-selection.But by the material of RS-485 Computer signal data cable it can be seen that its anti-flammability
Can be very poor；And the increase year by year of electrical fire incidence rate in occurring along with fire, therefore the most urgent to electric wire fire protection requirement
Cut.At present, Electrical Safety is global problem, particularly when fire incident occurs, how to leave guarantee of sufficient time people
Safe escape, the loss of minimizing accident, ensure line security energising, signal unimpeded, how to improve key project, important field
The fire safety grade of institute, special dimension etc., is the cable industry diligent pursuit of research staff.
