Abstract
It the utility model is related to a kind of production line common control signal distributor, it is characterised in that：It includes a line instrument power supply power supply, two wires instrument power supply power supply, double diode, analog signalses isolation card, a line Distributed Control System and two wires Distributed Control System；One line instrument power supply power supply and two wires instrument power supply power supply are powered by double diode for field instrument, the input of the output end connection analog signalses isolation card of field instrument, the output end of analog signalses isolation card are connected in parallel a line Distributed Control System and two wires Distributed Control System.The utility model can not only cause field instrument signal to use or show to two separate production lines, and it effectively prevent mutual interference or influence, efficiently solve the problem that a field instrument signal is shown jointly, independently in two production lines, and using effect is notable, avoid the cost waste that two pieces of field instruments are installed for two production lines, any one production line maintenance is it also avoid, an other production line is had an impact.
Description
Technical field
Control signal distribution field is the utility model is related to, more particularly to a kind of production line common control signal distribution dress
Put.
Background technology
More than two production lines and multiple field instruments are set mostly in production workshop, in order to save space and build
This is set as, some field instrument signal is frequently necessary to the production line separate to two and uses or show, such as short in viscose glue
The liquid level signal of circulation water station in fiber production process.
Field instrument signal gives two separate production lines in the prior art（For the ease of describing, hereinafter referred to as one
Line and two wires）Using or display setting structure, as shown in figure 1, a line instrument power supply power supply 1 ' be field instrument 2 ' power, show
A line DCS is connected in series between two signal output parts of field instrument 2 '（Distributed Control System）3 ' and two wires DCS 4 ', thus may be used
See, the signal output part of field instrument 2 ', a line DCS3 ' and two wires DCS 4 ' form an annular signal circuit, if a therefore line
Power-off maintenance, necessarily affects use or display of the signal of field instrument 2 ' on two wires DCS 4 '；If a line DCS3 ' power-off is examined
Repair, use or display of the signal of field instrument 2 ' on two wires DCS 4 ' will necessarily be influenceed, conversely, as the same.Show and change places, it is existing
There is field instrument signal in technology when being used to two separate production lines or display, can disturb between each other or shadow
Ring, and then influence manufacturing schedule, cost of idleness, be not convenient to use.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of production line common control signal distributor, no
But field instrument signal can be caused to use or show to two separate production lines, and effectively prevent mutual do
Disturb or influence.
To achieve the above object, the utility model takes following technical scheme：A kind of production line common control signal distribution
Device, it includes a line instrument power supply power supply, two wires instrument power supply power supply, double diode, analog signalses isolation card, a line collection
Dissipate control system and two wires Distributed Control System；The one line instrument power supply power supply and the two wires instrument power supply power supply pass through institute
State double diode to power for field instrument, the output end of the field instrument connects the input of the analog signalses isolation card
End, the output end of the analog signalses isolation card are connected in parallel the collecting and distributing control of the line Distributed Control System and the two wires
System.
Two inputs of the double diode are electrically connected line instrument power supply power supply and two wires the instrument power supply electricity
The output end in source, the output end electrical connection instrument power terminal of the double diode, and be institute by the instrument power terminal
Field instrument power supply is stated, and the double diode and the instrument power terminal are integrated and be fixed as one.
The one line instrument power supply power supply and the two wires instrument power supply power supply are arranged to 24 volts.
The output signal of the field instrument is 4~20MA.
For the utility model due to taking above technical scheme, it has advantages below：1st, the utility model is double by setting
Diode integrates a line instrument power supply power supply and two wires instrument power supply power supply, and then is powered for field instrument, therefore ensure that existing
The double circuit power supply of field instrument so that any one production line power-off maintenance does not interfere with the normal work of field instrument；This
Utility model sets a line DCS and two wires DCS to be parallel to analog signalses isolation card by setting analog signalses isolation card
Output end, therefore field instrument signal has been effectively ensured and independently can have been used or shown on a line DCS and two wires DCS, entered
And it effectively prevent mutual interference or influence.2nd, the utility model is due to double diode and instrument power terminal being integrated
It is fixed as one, therefore is highly convenient for installing and uses.The utility model design structure is simple, and cost is low, can extensive use
Field is distributed in the control signal of various production lines.
Brief description of the drawings
Fig. 1 is the structural representation that field instrument signal is used or shown to two independent lines in the prior art；
Fig. 2 is structural representation of the present utility model.
Embodiment
It is described in detail with reference to the accompanying drawings and examples to of the present utility model.
As shown in Fig. 2 production line common control signal distributor of the present utility model includes a line instrument power supply power supply
1st, two wires instrument power supply power supply 2, double diode 3, analog signalses isolation card 4, a line DCS5 and two wires DCS 6；
One line instrument power supply power supply 1 and two wires instrument power supply power supply 2 are powered by double diode 3 for field instrument 7, scene
The input of the output end connection analog signalses isolation card 4 of instrument 7, the output end of analog signalses isolation card 4 are connected in parallel
One line DCS5 and two wires DCS 6.
In a preferred embodiment, for the ease of installing and using, two inputs of double diode 3 are electrically connected
The output end of one line instrument power supply power supply 1 and two wires instrument power supply power supply 2, the output end electrical connection instrument power of double diode 3
Terminal 8, and be that field instrument 7 is powered by instrument power terminal 8, and double diode 3 and instrument power terminal 8 are integrated and are fixed as
One.
In a preferred embodiment, a line instrument power supply power supply 1 and two wires instrument power supply are actually needed according to scene
