Description

A kind of industrial data Communication Gateway

Technical field

This utility model is related to a kind of gateway, particularly to a kind of industrial data Communication Gateway.

Background technology

In enterprise automation and Information-based Item, need to solve interconnection between various distinct devices, system with integrated. The Diversification Problem of communication modes and communications protocol exists always, and more and more prominent, and engineers and technicians need to put in a large number Time and efforts solve heterogeneous system between interconnected communication.

Produce department and being on the increase that other departments connect each other with Endogenous, just when the water comes, a channel is formed for the use of gateway ?.It was verified that the advantage using gateway includes：Information can be obtained from other links of equipment and supply chain, can be given it He provides real-time production data at system（Improve practicality and the effectiveness of production information）, and can in production line, company very To the other end being the world, system is remotely developed and is safeguarded, premise is to have suitable safe clearance authority.

For the manufacturing link of enterprise/supply chain, storage, engineering design, market, sale, after-sale service etc. are arbitrary Any system in link or level, gateway is all that they provide the approach that a data imports and derives.Gateway is equivalent to One actuator every aspect being connected each other together, and old serial communication network or analogue signal are connected to newly Digital network.

Further, since technical grade Ethernet protocol species is various, information may need to carry out between various protocols conversion and Inverse conversion.The gateway of some technical grades can realize the interactive transmission of information between wire line protocols and wireless protocols.

Equipment in Industry Control more and more employs smart machine, from tape controller, but all disunities, have Using the communications protocol of standard, have using self-defined communications protocol, be that the Centralized Monitoring of data causes very big problem.

Meanwhile, currently the internet of things data acquisition commonly used and communication module itself do not possess data processing and information pipe Reason function, to be carried out the process of data, and to ignore equipment itself in information control terminal computer using various management softwares The data collection and administration function that should possess, corresponding field data of often redeveloping in the equipment Foundations developed is adopted Collecting system, which results in compatibling problem and the equipment cost problem of equipment month information acquisition system itself.And software and hardware Preferably not compatible between system, many data acquisitions are all to be obtained by the way of manual collection, do not possess good Reliability and real-time, are not suitable for large-scale Product Data Management.

Utility model content

In view of this, this utility model provides a kind of industrial data Communication Gateway, by setting serial ports transmitting-receiving in gateway Device, buffer and processor are so as to possess data processing and information management function.

This utility model is solved the above problems by following technological means：

A kind of industrial data Communication Gateway of the present utility model, including：Serial ports transceiver for data acquisition；For counting Buffer according to storage；For reading data from described buffer, and gateway and real equipment are judged according to communication status word Between communications status processor, described serial ports transceiver electrically connected with described buffer；Described buffer and described process Device electrically connects；Described processor passes through Ethernet and the next mechatronics；The number of described slave computer is two or more.

Further, described serial ports transceiver adopts MAX3079E technical grade module, simultaneously compatible RS485 and RS422 electricity Flat.

Further, described processor is electrically connected by 100M Ethernet interface with described slave computer, supports MODBUSTCP association View, supports 8 physical connections.

Further, described buffer adopts 64K running memory, 1M data buffer storage.

Further, described processor is 32 arm processors.

A kind of industrial data Communication Gateway of the present utility model, by gateway arrange serial ports transceiver, buffer and Processor, so as to possess data processing and information management function, can be analyzed, classifies and locate to the data collecting Reason, distal information collection central computer need not be installed special data management software, convenient, fast, efficient and saving life Produce cost.

Brief description

With reference to the accompanying drawings and examples this utility model is further described.

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1：A kind of industry number of the present embodiment According to Communication Gateway, including：Serial ports transceiver for data acquisition；Buffer for data storage；For from described caching Reading data in device, and the processor of the communications status between gateway and real equipment, described string is judged according to communication status word Mouth transceiver is electrically connected with described buffer；Described buffer is electrically connected with described processor；Described processor passes through Ethernet With the next mechatronics；The number of described slave computer is two or more.

As the improvement further of technique scheme, described serial ports transceiver adopts MAX3079E technical grade module, with When compatible RS485 and RS422 level.

As the improvement further of technique scheme, described processor and described slave computer pass through 100M Ethernet interface electricity Connect, support MODBUSTCP agreement, support 8 physical connections.

As the improvement further of technique scheme, described buffer adopts 64K running memory, 1M data buffer storage.

As the improvement further of technique scheme, described processor is 32 arm processors.

Specifically, described processor and upper machine communication adopt communications protocol TCP/IP EPA, communication speed Up to 100MB, and long transmission distance, communication robust reliability.

For the next equipment, our gateway, as data acquisition main website, by serial ports transceiver by the next equipment Data read in gateway in, put into buffer after parsing, and the communication state with this equipment be converted to communication state word and also protect Deposit in both the buffers.For host computer, our gateway, as the slave station providing data, reads data from buffer, and Judge the communications status between gateway and real equipment according to communication status word.

This gateway that this utility model provides can be acquired to the data of different agreement, parsing, then by significant figure Repacked according to according to the agreement setting, the baud rate of the no longer controlled device talk of host computer acquisition rate limits, There is no concern that multiple host computers can impact to control system, can support that up to 8 host computers gather simultaneously, thoroughly break away from string Jaws equipment can only support a host computer, and the slow shortcoming of communication speed.

Due to using protocol conversion, the equipment of 4 kinds of different agreements of lower floor can be converted to same agreement, upper strata is controlled Terminal reading data processed is simply efficient, eliminates multiple data management softwares, saves production cost in a large number.

Finally illustrate, above example only in order to the technical solution of the utility model to be described and unrestricted, although ginseng According to preferred embodiment, this utility model is described in detail, it will be understood by those within the art that, can be to this The technical scheme of utility model is modified or equivalent, the objective without deviating from technical solutions of the utility model and model Enclose, it all should be covered in the middle of right of the present utility model.
