Embodiment
In data transmission procedure, if the two ends of transmission, such as side a and b, when distance is very near (such as at same room or in 100 meters), transfer of data so between two ends is easy to carry out, can USB data line be passed through, WIFI signal, netting twine, Serial Port Line, bluetooth, RS485 bus, or CAN carries out transfer of data.And distance between side a and b slightly large time, such as 2KM, now USB data line, WIFI signal, netting twine, Serial Port Line, bluetooth is all helpless, because this distance has exceeded their transmittability.Therefore usually adopt RS485 bus, because it is reliable, simple, cost is low, especially at production field, in the scene of a such as factory, a farm or a heavy construction, the distance of transmission is roughly all near this yardstick.Therefore develop and apply very widely.This " fieldbus " solves the local communication problem of comparatively remote (about 2KM), and match therewith, a lot of configuration software also corresponding being developed connects corresponding equipment, from this equipment from obtaining data and controlling.
The syndeton of the equipment (being generally computer) of field apparatus, loading configuration software as shown in Figure 1, wherein, the equipment loading configuration software is connected by fieldbus with field apparatus, the data of each field apparatus can be obtained and shown by display, and the operation of response user, to the field apparatus sending controling instruction of specifying to perform corresponding control.
Along with the development of society, there is limitation in said structure: said structure designs based on certain transmission range (about 2KM), the transmission demand of longer distance cannot be met, in other words, if meet the transmission demand of longer distance, need to build special circuit, the cost brought thus will greatly increase.And in today of the Internet extensive use, we can expect the transfer of data helping realize long distance by the Internet.But inventor finds after research, implement to concrete needs from idea and overcome one difficulty after another, such as, have following difficult point:
Difficult point 1, existing " equipment " are based on industry, and the intelligence degree of equipment is very limited.And due to the demand that most equipment is not surfed the Net, add the reason that the hardware cost of function of surfing the Net is higher, present most equipment do not have function of surfing the Net.In addition, the Fieldbus Based numerous configuration software developed now has done fairly perfect, if eliminate the transmission means of fieldbus, then these configuration softwares will along with being eliminated, need again to find substitute on the one hand, also belong to the waste of resource (man power and material that exploitation drops into) on the other hand.Above reason, the communication modes all describing fieldbus cannot be abandoned and can be continued to follow.And under the prerequisite of communication modes retaining fieldbus, how it to be merged mutually with the Internet has been exactly a difficult problem.
The type of difficult point 2, the webserver (such as Cloud Server) is numerous, and relative communication protocol also has countless versions, does not have unified specification.For user, the particularly user of production scene, itself is just stranger to the Internet and Cloud Server, substantially the technical ability using Cloud Server is not possessed, this just causes them cannot independently solve network-related problems, if and allow network engineers get involved in industry spot, then on the one hand inconvenient, human cost is higher on the other hand.
After further research and test, propose a kind of bridge joint scheme, the program is by the terminal of loading configuration software of a kind of bridging device side by fieldbus connection industry spot, and opposite side connects Cloud Server by the Internet for inventor.Two kinds of distinct transmission forms (fieldbus mode and interconnected network mode) are carried out bridge joint, thus the transfer of data that can realize between industry spot and remote equipment (as server), and without the need to the equipment operating mode that changes industry spot personnel or custom.Convenient, ingenious and efficiently solve above-mentioned two difficult points.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
