Embodiment
As shown in figure 1, the present invention network management region in combustion gas use state management system, including to using fire
The gas meter, flow meter 1 that gas is measured, multiple concentrators 2 of gas meter, flow meter information in respective regions are collected, collect each concentrator information
Administrative center 3, the administrative center 3 are connected by network with remote server 4, and the remote server 4 is provided by third party
And remote server provides dedicated management platform for different combustion gas providers.
The present invention gathers the use data of all gas user gas meter, flow meters 1 in respective regions, specific collection by concentrator
The middle quantity of device 2 is set according to the size in region and its control range size, the gas meter, flow meter data transmission that each concentrator 2 is received
To administrative center 3, administrative center 3 can be the Net MUX that can surf the Net or computer with networking capability,
The equipment such as terminal, after administrative center 3 receives related data, take collect, compress, encrypting etc. that finger is sent to by network after mode
Fixed place, while administrative center 3 and reception are directed to the relay centre of various control instructions in this region；Administrative center 3 is in number
According to processing procedure in, the data of reception directly can also be sent to remote server 4, be handled by remote server 4 all
Information, can so reduce dependence and maintenance to local device as far as possible.Remote server 4 in the present invention is by third party
The dedicated management platform of offer, all business that can be directed to same industry provide service, reduce the meter reading people of combustion gas provider
Member, the quantity of attendant, are same as being preferably minimized its needs to technical elements, failure, maintenance, the technology branch of all devices
Hold etc. and all to be completed by third party, combustion gas provider only needs to be grasped the gas consumption of each user in its region, and checks each combustion
Whether gas user normal use and pays the items such as expense, can be to for other technical problems relevant with hardware device
Third party proposes and solved by it.The present invention can make combustion gas provider be in management status, be concerned about tool therein without spending
Body acts, and reduces its technology expenditure and personnel's expenditure, attacks art industry.
The solution of the present invention avoid combustion gas provider in the prior art from purchase table, be installed to management, safeguard among institute
There is step, after entrusting to the third party with more correlation technique ability by it, set up by third party by the requirement of combustion gas provider
Corresponding acquisition system, management mode, because the final purpose of combustion gas provider is exactly to grasp the specifically used amount of gas user
And corresponding expense is collected according to quantity, equipment purchase therein, to build, manage, safeguarding etc. be all burden for it, nor it should
Some functions, and third party is conventionally the technical community for possessing corresponding qualification, its buying to equipment, builds, manages and ties up
Shield is more professional, using the teaching of the invention it is possible to provide more preferable scheme, while third party provided as it technology, the maintenance side of equipment, combustion gas carries
