Description
Technical field
The present invention relates to the operation and management field of gas station, especially a kind of things-internet gateway equipment of serving gas station, specifically a kind of by electronic technology, technology of Internet of things and Internet technology, realized interior various hardware device and the system of standing, and the gas station operation networking of flow process and the gas station Intelligent internet of things gateway of centralized management.
Background technology
At present, along with the Chinese government is to day by day the paying attention to and the encouragement of relevant supporting policy of environmental protection, energy-saving and emission-reduction work, new forms of energy are used widely in automobile industry, and have become the trend of industry development.Wherein natural gas is exactly one of low-carbon (LC) new forms of energy.The natural gas of usining reduces more than 90% as the automobile CO2 emission of fuel than gasoline car.Its economy, the features such as low pollution become civilian vehicle to the ideal complement of regular gasoline or alternative fuel.The amplification of China's natural gas automobile quantity is annual more than 20%.According to expert, estimate, between following 5 to 10 years, China's natural gas automobile pollution will reach 5,000,000, and newly-built automobile gas filling station is reached more than 15000.
In recent years the recoverable amount of filling gas station equipment increase rapidly to its safeguard, operation and management brought stern challenge.In each gas station, exist a large amount of equipment need to carry out field management and remote monitoring, as storage tank, voltage regulator, gasifier, charging machine, pipeline etc., and pressure, temperature, humidity, strength of fluid, the detector devices such as flame.These equipment are mainly connected on PLC rack by agreements such as CAN, RS485/RS232, or connect arrive at a station control main frame or retail host computer.This mainly brings the problem of two aspects: 1. in station, the communication between each equipment and transfer of data all adopt equipment vendors' proprietary protocol substantially, lack unified standard and industry standard.2. each station system relative closure all.Soft and hardware in standing becomes genuine " built-in system ".The problem of this two aspect is that data acquisition, business integration and the telemanagement of gas station operator brings great difficulty above, seriously hinders the Global Informationization of operator and builds and advance implementation.

Accompanying drawing explanation
Fig. 1 is gateway function four layer architecture schematic diagrames of the present invention.
Fig. 2 is the schematic diagram of gateway of the present invention practical application in gas station.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 2, the hardware system in the station of a typical station system is mainly by comprising filling machine, air accumulator, gasifier, valve, and other equipment form.Conventionally, these equipment are connected to on-the-spot PLC above by each equipment manufacturer's proprietary protocol, then carry out communication by PLC with station control host computer, the instruction of receiving station's control host computer, and to its transmission data.These equipment have formed the system running environment of a sealing.Although this system itself can realize the on-the-spot management to station equipment, operator almost cannot carry out remote data acquisition, business integration to this system, and unified management.
After having increased " intelligent gateway " of the present invention equipment, above all restrictions are effectively got rid of: intelligent gateway utilizes the abundant hardware interface that himself physical layer provides to be connected with the various kinds of equipment of different vendor, and portion completes protocol conversion within it, the data transaction that distinct device is sent by privately owned communications protocol becomes unified data format, and is stored in himself embedded database.Remote-Data-Interface by the multiple standards that provides in gateway application layer sends to long-range data center by the data of consolidation form again.In this way, only such intelligent gateway need to be installed in each gas station, in gas station, distinct device just can " translation " be become unified form by real time with the information of system, and is transferred to safely the data platform of operator.By dispose intelligent gateway in gas station, the equipment of gas station can be concentrated to effectively management, and can carry out remote monitoring in general headquarters of unit of operation, improve filling gas station equipment management and control dynamics and improve information-based business integration ability, form three unifications of " consolidation form ", " unified platform ", " unified management ".
The realization of this gateway functions of the equipments adopts 4 layer architectures, bottom-up being respectively: physical layer, and protocol conversion layer, data access layer, application layer, as shown in Figure 1.The effect of every layer is respectively:
Physical layer: be positioned at the bottom of 4 layer architectures, its major function is for comprising that the equipment such as PLC, filling machine, storage tank, voltage regulator, gasifier provide interface and the data physical link of multiple hardwares agreement.Physical layer comprises RS485 except providing, RS232, and CAN, the hardware protocol that LIN etc. are conventional, also provides the hardware interface based on analog/digital input and output.
Protocol conversion layer: be positioned on physical layer.Its major function be physical layer is provided from different manufacturers, the data transaction that the communications protocol of distinct device is transmitted becomes the protocol data form that gateway is unified.
Data access layer: this layer is in charge of the data access of gateway device inside and data in the storage of intra-gateway.These data mainly come from various parameters and the numerical value that protocol conversion layer provides, and store in the embedded database of gateway, and when device looses power, these data can not be lost.
Application layer: this layer is the superiors of 4 layer architectures.It provides the far call interface of unifying and meet flexibly international standard, comprises WebService, FTP and HTTP.Utilize these interfaces, gateway can with the pattern of automatic or manual by data-pushing the server to far-end, or initiatively access gateway by remote server, ask and obtain data.In addition, for order or the request of controlling type, application layer directly access protocal conversion layer to realize associative operation.Application layer is the data-interface to upper strata as gateway device, and perfect security access mechanism is provided, and comprises data M D5, and AES encrypts, the modes such as authentication.
The design of this 4 layer architecture is externally used gateway as a black box.Operator no longer needs to understand on-the-spot each producer, the proprietary protocol bunch that each equipment is huge and complicated, just can select neatly required every data of obtaining, and with cheap cost by the data network at each station, form the data center of oneself, realize on a platform to different gas stations station equipment with and separately the networking of daily operation, the demand of centralized management.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
