Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is that a kind of remote fuel gas of the invention reads intelligence control system figure；
Fig. 2 is the flow chart that the present invention realizes remote fuel gas reading.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Refering to Figure 1, a kind of remote fuel gas reading intelligence control system is mainly by control system module 3, communication mould
Block 6, analog-to-digital conversion module 4, gas flow metering module 5, display module 7, server module 2, gas company's human-computer interaction behaviour
Make management platform 1 to form；Wherein, display module 7 includes：Gas values show 702 and combustion gas cumulative volume value reality when previous payment
When show 702；Server module 2 includes：Primary server 202 and backup server 201；
Communication module 6 uses the Wireless Data Transmission Terminal or wireless WiFi of model USR-GPRS-730；
Analog-to-digital conversion module 4 uses the high-speed AD analog-to-digital conversion module of model ADS822E；
It is existing gas meter equipment that gas flow, which measures module 5,；
In the following, the specific implementation process of the calculating of gas consumption value, storage, update and remote reading is described in detail：
As shown in Figure 1, combustion gas flows through gas meter amount module 5 by gas pipeline, it is then defeated that gas flow measures module 5
The analog signal of metering gas flow out, analog signal are converted into digital signal through analog-to-digital conversion module 4 and are input to control system
The central processing unit of module 3 is carried out data processing and the meter of digital signal by the central processing unit of control system module 3
It calculates, calculates gas consumption value in real time；Control system module 3 will real-time calculated gas consumption value number by communication module 6
According to module 2 of uploading onto the server.
Server module 2 has 201 liang of set servers of primary server 202 and backup server, while is believed substantially owner
Breath and gas consumption Value Data are stored and are updated；Server module 2 stores the essential information of the owner in administrative area
The data updated with corresponding gas values；Data storage and update are carried out using two server, even if wherein a set of server occurs
Failure or damage lead to loss of data, and other set server can continue data storage in time and update, to keep
The safety and timeliness they data storage and updated.
It is aobvious by display module 7 while gas consumption real value is uploaded to server module 2 by control system module 3
Gas values and display real-time combustion gas cumulative volume value when showing previous payment；Gas values and reality when display module 7 shows previous payment
When combustion gas cumulative volume value mainly for owner carry out combustion gas payment when a kind of verification of amount is provided；Gas company administrative staff are logical
Gas company's man-machine interactive operation management platform 1 directly access server module 2 is crossed, that is, the gas consumption value of owner can be read,
To carry out combustion gas expense calculating, owner is notified to carry out combustion gas payment in time.
Gas values hair of the owner after combustion gas reimbursement of expense platform completes payment, when server module 2 then pays the fees this
Send to control system module 3, control system module 3 then timely update the previous payment in display module 7 when gas values；Combustion gas
Company's man-machine interactive operation manages platform 1, and there are both links to access server, i.e. primary link and backup link；Primary link connection
Primary server；Backup link connects backup server.
Under normal circumstances, man-machine interactive operation management platform 1 in gas company's accesses main service by primary link and carries out combustion gas
The reading of volume value；When primary link or primary server break down or damage, gas company's man-machine interactive operation management is flat
Platform 1 then accesses the reading that backup server carries out combustion gas stream magnitude by backup link；When any link or server
It breaks down or damages, then repair and replace in time, to be further ensured that the safety and integrality of data.
It is illustrated in figure 2 the detailed process that gas company administrative staff remotely read the gas consumption value of owner；Combustion gas is public
Department administrative staff manage the inquiry mode that platform 001 is from top to bottom successively managed by gas company's human-computer interaction and read often
The gas consumption value of family owner；The area 002 that platform selecting city is divided is managed by human-computer interaction, selects the residence in institute's partition
People's cell 003 selects the building generic term for a building, e. g. Apartment, store, a movie theater, etc. 004 of residential area, selects owner's room number 005, reads the gas consumption value 006 of owner, will
The gas consumption Value Data of reading is stored in combustion gas fare payment system 007；Managing platform 001 by gas company's human-computer interaction can realize
The gas consumption value of all owners in Integrated query fragment area, easy to operate, gas values reading efficiency height.
A kind of remote fuel gas reading intelligence control system of the invention and its implementation are as above, can effectively reduce combustion gas public affairs
Manpower output is taken charge of, gas values reading efficiency is improved.
