Abstract
The invention is applicable to the technical field of cables, and provides a fuel data cable transmission device. The fuel data cable transmission device comprises a plurality of fuel data instruments, a plurality of modulators, a coaxial cable transmission network and a concentrated collector, wherein the modulator collects and acquires data of the fuel instruments and outputs the collected fuel data to the coaxial cable transmission network, and then the collected fuel data are transmitted to the concentrated collector, so that the defect of fuel data communication in an intelligent grid in the prior art is overcome. When the fuel data are transmitted by the coaxial cable transmission network, wires are not needed to be additionally distributed; and moreover, the coaxial cable transmission network has the characteristics of low interference, low loss, high anti-jamming property and stable impedance.
Description
Technical field
The invention belongs to the combustion gas data communication technology field, relate in particular to a kind of combustion gas data cable transmitting device.
Background technology
485 communication interfaces are a kind of common interfaces of the common use of industrial communication equipment, adopt the twisted-pair feeder mode of connection of two-wire system as the one of which, and this mode of connection is the bus type topological structure, promptly on same bus, can articulate 32 nodes (gas meter, flow meter) at most.
But twisted-pair feeder is realized the transmission of combustion gas data and is existed than big defective, for example:
(1), the twisted-pair feeder difficulty of construction is big, and constructed easily and artificial destruction;
(2), various interference of noise;
(3), be subject to thunderbolt and over-voltage protection.
Summary of the invention
The object of the present invention is to provide a kind of combustion gas data cable transmitting device, there is the problem of defective in the bronze drum twisted-pair feeder transmission combustion gas data that being intended to solve prior art provides.
The present invention is achieved in that a kind of combustion gas data cable transmitting device, and said system comprises:
Some combustion gas data instrument;
Be connected through twisted-pair feeder with said some combustion gas data instrument, gather the some modulators that obtain the combustion gas data;
The concentric cable transmission network that said combustion gas data are exported;
Be connected with said some modulators through said concentric cable transmission network, and receive the concentrated collector of the combustion gas data of said concentric cable transmission network transmission.
As a kind of improvement, said each modulator is connected with several combustion gas data instrument through twisted-pair feeder.
As a kind of improvement, the layout that is connected of said concentrated collector and modulator comprises that Y-connection layout, chain connect layout, tree-like connection is arranged and annular is connected a kind of or two or more at least combination in the layout.
Combustion gas data cable transmitting device provided by the invention comprises some combustion gas data instrument, some modulators, concentric cable transmission network and concentrated collector; Wherein, The data of gas meter are obtained in the modulator collection, and the combustion gas data that collect are outputed to the concentric cable transmission network, are transferred to concentrated collector; Thereby overcome combustion gas data communication existing defective in the intelligent grid that prior art provides; Through concentric cable transmission network transmission combustion gas data, do not need extra wiring, and the concentric cable transmission network have low interference, low-loss, height is anti-interference and the characteristic of impedance stabilization.
Description of drawings
Fig. 1 is the framework synoptic diagram of combustion gas data cable transmitting device provided by the invention.
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Combustion gas data cable transmitting device provided by the invention comprises some combustion gas data instrument, some modulators, concentric cable transmission network and concentrated collector.
Fig. 1 has provided the structured flowchart of combustion gas data cable transmitting device provided by the invention, for the ease of explanation, has only provided the part relevant with the present invention among the figure.
Combustion gas data cable transmitting device provided by the invention comprises some combustion gas data instrument, some modulators, concentric cable transmission network and concentrated collector, wherein:
Some modulators are connected through twisted-pair feeder with some combustion gas data instrument, and this modulator is the CF signal that meets the transmission of concentric cable transmission network with the combustion gas data-switching of RS-485 communication interface mode transfer with combustion gas data instrument.
Concentrate collector to receive the combustion gas data of concentric cable transmission network transmission; These combustion gas data exist with the CF signal pattern; Concentrated collector is converted into the RS-485 communication pattern; And the combustion gas data transmission after will changing is to the Surveillance center of far-end, and the communication pattern that is transferred to Surveillance center comprises communication patterns such as GPRS, at this not in order to restriction the present invention.
Wherein, above-mentioned concentric cable transmission network is existing concentric cable in order to transmission cable television digital signal, and it has been ripe communication wires network, i.e. concentric cable transmission network;
Relative, twisted-pair feeder is all adopted in wiring of the prior art, realizes being connected of combustion gas data instrument and concentrated collector, causes existing difficult wiring, receives problem such as external interference;
And combustion gas data cable transmitting device provided by the invention adopts the existing coaxial cable transmission network to carry out the transmission of combustion gas data, efficiently solves the problem of above-mentioned technology, and has simplified the inside structure of transmitting device, has reduced cost, concrete as follows:
For example do not need extra wiring, and be difficult for by artificial destruction; The transmission frequency of combustion gas data adopts high-frequency signal transmission, and strong anti-interference performance has been avoided the influence of extraneous factors such as being struck by lightning; Simultaneously, improve the reliability and the confidentiality of transmission data.
In the present invention; Concentrate being connected of collector and modulator to arrange and comprise that Y-connection layout, chain connect layout, tree-like connection layout is connected a kind of or two or more at least combination in arranging with annular; It is the set-up mode of the concentric cable transmission network net that provides of prior art; Can have multiplely, repeat no more at this, but not in order to restriction the present invention.
Combustion gas data cable transmitting device provided by the invention comprises some combustion gas data instrument, some modulators, concentric cable transmission network and concentrated collector; Wherein, The data of gas meter are obtained in the modulator collection, and the combustion gas data that collect are outputed to the concentric cable transmission network, are transferred to concentrated collector; Thereby overcome combustion gas data communication existing defective in the intelligent grid that prior art provides; Through concentric cable transmission network transmission combustion gas data, do not need extra wiring, and the concentric cable transmission network have low interference, low-loss, height is anti-interference and the characteristic of impedance stabilization.
