Embodiment
The present invention is more specifically described in detail with reference to specific embodiment.
Embodiment
Such as Fig. 1~Fig. 4;The multi-protocol data access device that can configure under industrial 4.0 environment of the present invention, including terminal configuration Software, configuration file and by be deployed in manufacture scene application layer multi-protocols access card constitute;Terminal configuration software includes compiling The application layer protocol Knowledge Base Module collected, human-computer interaction interface, security module;Multi-protocols access device includes microprocessor, should With layer multi-protocols access port, memory module, protocol switching program, universal asynchronous transmitter (UART), radio receiving transmitting module.
Such as Fig. 1;Terminal configuration software includes pressing the application layer of distributed structure/architecture editor according to the existing device protocol feature of manufacture Communication protocol storehouse;
Protocol library includes:The protocol type that can access on access card, agreement access address, on certain interface the agreement work State and the current data transmission parameters of the type agreement etc..When the equipment that there is new agreement manufacturing shop is added or removed, Editable changes the agreement in protocol library.
Human-computer interaction interface:When new manufacturing equipment will be accessed, what operating personnel can transmit according to the device data should With layer protocol information and the demand of data transfer, dynamically configuration protocol parameter, completes new agreement access;When manufacture is set During standby completion data transfer, operating personnel can configure file again, terminates the agreement transmission work, vacates resource and space.Configuration The operational data form of the agreement can be generated after the completion of task, protocol library information updating is inquired about for operating personnel, realized to configuration The real-time tracking monitoring of implementation status;, can be more in ensuing configuration work and operating personnel are by monitoring information Flexibly selection, greatly reduces workload, configuration task is become more simple.
Security module:It is required that to protocol database information carry out demand for safety protection pair protocol database information Safeguard protection is carried out, is gone wrong to prevent protocol database or is broken into and causes information to lose, reveal, be modified; Want relaying configuration module so as not to because operating mistake or other problemses and caused by configure disorderly, influence protocol configuration and data transfer Process.
Such as Fig. 2;Four parts of application layer protocol configuration file format point:Protocol type section, address field, functional section and data Configured transmission.The identifier of title comprising agreement and the agreement, such as RS-232, RS-485, Zigbee, work in protocol type section Industrial Ethernet etc.;The address that sets when access address section is the access of certain agreement, it and protocol switching program address shape in access card A mapping in a pair, i.e., a kind of application layer protocol is in access, and configuration file can drive corresponding protocol switching program and start Device protocol in the interface of the correspondence agreement, non-protocol library can not be accessed.Configuration feature section is the work choosing of the decision-making interface Select, such as new access protocol starts to transmit termination after the completion of data, transformation task, it is to avoid Internet resources are excessively taken;Configuration ginseng Several sections are that the access protocol can transmit the parameter of data, the starting of such as data format with configuration according to current environment reasonable definition Position, data bit and stop position and the baud rate of explanation data transmission speed etc..
It is hardware structure of the present invention such as Fig. 3;It includes microprocessor, various protocols access port, memory module, UART, nothing Line transceiver.Manufacturing equipment protocol type is numerous under industrial 4.0 environment, and algorithm is complicated and changeable, and data traffic generally all compares It is larger, therefore the processor of Selecting operation speed comes running configuration file and protocol switching program, one piece of agreement access card The application layer protocol of four types can be accessed.The function of wireless transceiver is to receive the configuration file remotely sent, and is Terminal sends implementation status information.Memory module point FlashROM and cache blocks two parts, FlashROM are received for storage Configuration file and protocol switching program and each agreement address and relevant parameter, new agreement access and perform after storage update letter Breath.Cache module is used for when the data traffic of transmission is very big, and in order to avoid microprocessor overloads, partial data is temporarily delayed Deposit.UART is used for the serial parallel conversion of data transfer between equipment interface and microprocessor.
It is configuration flow figure of the present invention such as Fig. 4;When new equipment access, operating personnel are according to the application layer of the equipment Specific parameter is configured the need for protocol type and data transfer, configuration file is issued to access card by wireless network, by wireless Transceiver is stored in FlashROM after receiving, the file address in microcomputer reads Flash PROM, is adjusted according to its address With corresponding protocol switching program, the access of manufacturing equipment is completed using the agreement, data transfer and association are determined by configuration parameter Discuss Remote configuration process.This equipment can Remote configuration protocol data access, the configuration parameter such as baud rate.Furthermore, it is possible to root According to specific network condition, by writing the multi-protocols changeover program with Do statement, the timesharing to each protocol devices data is realized Transmission.
As described above, the present invention can be better realized.
Embodiments of the present invention are simultaneously not restricted to the described embodiments, other any Spirit Essences without departing from the present invention With the change made under principle, modification, replacement, combine, simplify, should be equivalent substitute mode, be included in the present invention Within protection domain.
