The following describes in detail a data transmission device, a method and a system provided in an embodiment of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a data transmission device according to an embodiment of the present application. As shown in fig. 1, the data transmission device 10 includes a processing module 11 and at least one interface module 12. The processing module 11 is connected to each interface module 12. Each interface module 12 may be connected to at least one free message device 20 and the processing module 11 may be connected to an information management system 30. The interface module 12 may receive the first data from the free message device 20 through the first communication protocol, and send the first data to the processing module 11, and the processing module 11 may perform format conversion on the first data, and send the format-converted first data to the information management system 30 through the second communication protocol.
The free message device 20 communicates through a first communication protocol, the information management system 30 communicates through a second communication protocol, the first communication protocol and the second communication protocol are different types of communication protocols, and because the message formats of the different types of communication protocols are different, the free message device 20 cannot analyze the message of the second communication protocol, and the information management system 30 cannot analyze the message of the first communication protocol, the free message device 20 and the information management relationship 30 cannot directly communicate.
Each interface module 12 may be connected to at least one free message device 20, and for a plurality of free message devices 20 connected to the same interface module 12, the message devices 20 may respectively communicate with the interface module 12 by using the same first communication protocol, or may communicate with the interface module 12 by using different first communication protocols. When the processing module 11 is connected to a plurality of interface modules 12, the free message devices 20 connected to different interface modules 12 may communicate with the connected interface modules 12 by using the same first communication protocol, or may communicate with the connected interface modules 12 by using different first communication protocols.
When the plurality of free message devices 20 connected to each interface module 12 communicate with the connected interface module 12 by using the same first communication protocol, the processing module 11 may perform format conversion on the first data from different free message devices 20 by using the same data format conversion method, so that the converted first data conforms to the second communication protocol. When the plurality of free message devices 20 connected to each interface module 12 communicate with the connected interface module 12 using at least two different first communication protocols, the processing module 11 performs format conversion on the first data from the different free message devices 20 respectively by using a data format conversion method corresponding to the first communication protocol according to the first communication protocol used by each free message device 20, so that the converted first data conforms to the second communication protocol.
Alternatively, the processing module 11 may be a processing device with data processing capability, such as a Raspberry Pi (risi), a single chip microcomputer (scm), or a Field Programmable Gate Array (FPGA). The first communication protocol may be an RS-485 protocol or an RS-232 protocol, etc., and the second communication protocol may be an OPC UA protocol.
In this embodiment of the application, after the interface module 12 is connected to the free message device 20, the first data sent by the free message device 20 may be received through the first communication protocol, and the first data is sent to the processing module 11, the processing module 11 may perform format conversion on the first data, so that the format-converted first data conforms to the second communication protocol, and then the processing module 11 may send the format-converted first data to the information management system 30 through the second communication protocol, so as to implement communication between the free message device 20 and the information management system 30, and it is not necessary to manually enter the data of the free message device 20 in the information management system 30, thereby reducing labor intensity.
Fig. 2 is a schematic diagram of a data transmission apparatus according to an embodiment of the present application. As shown in fig. 2, the data transmission device 10 includes an input module 13 in addition to the processing module 11 and the interface module 12. The input module 13 is connected to the processing module 11. The input module 13 may receive the association information corresponding to the first data and transmit the association information to the processing module 11, and the processing module 11 may associate the association information with the first data and transmit the association information to the information management system 30 through the second communication protocol.
After the interface module 12 receives the first data sent by the free message device 20, the input module 13 may receive associated information corresponding to the first data, the interface module 12 sends the first data to the processing module 11, and the input module 13 sends the received associated information to the processing module 11. After receiving the first data and the corresponding association information, the processing module 11 associates the first data with the association information, and sends the associated first data and the associated information to the information management system.
In the embodiment of the present application, the interface module 12 receives the first data, the input module 13 receives the association information corresponding to the first data, and the processing module 11 associates the first data with the corresponding association information and sends the associated first data and the associated information to the information management system 30, so that the information management system 30 performs data processing and data analysis conveniently, and because the association information does not need to be manually entered into the information management system 30, the labor intensity can be further reduced.
In one possible implementation, the input module 13 may include a touch screen. The user inputs the associated information through the touch screen, the input module 13 sends the associated information to the processing module 11, and after the interface module 12 sends the first data corresponding to the associated information to the processing module 11, the processing module 11 associates the associated information with the corresponding first data. For example, the user inputs the product batch information through the touch screen, the product batch information is sent to the processing module 11 by the input module 13, after the processing module 11 receives the product weight data sent by the interface module 12, the processing module 11 associates the product weight data with the product batch information, and then sends the associated product weight data and product batch information to the information management system 30.
In the embodiment of the present application, the input module 13 includes a touch screen, and a user can more conveniently input the associated information through the touch screen, so as to improve the use experience of the user. Since the touch screen has a display function and an information input function, a user inputs related information through the touch screen, which can reduce components included in the input module 13 and ensure that the data transmission device 10 has a lower cost.
In one possible implementation, the processing module 11 is connected to the interface module 12 and the Input module 13 through a General-Purpose Input/Output (GPIO) interface.
Optionally, the processing module 11 is connected to a GPIO bus, and the interface module 12 and the input module 13 are both connected to the GPIO bus through GPIO interfaces, so as to implement connection between the processing module 11 and the interface module 12 and the input module 13.
In the embodiment of the present application, since the GPIO interface is a data communication interface commonly used in the industrial field, the commonly used processor supports the GPIO interface, most of the input devices and the interface conversion device support the GPIO interface, the processing module 11 is respectively connected to the interface module 12 and the input module 13 through the GPIO interface, which can reduce the requirements on the interfaces included in the processing module 11, the interface module 12, and the input module 13, and thus can adopt the commonly used device as the processing module 11, the interface module 12, and the input module 13, thereby ensuring that the data transmission device 10 has a lower cost.
The GPIO interface has a high data transmission security, and the processing module 11 is connected to the interface module 12 and the input module 13 through the GPIO interface, respectively, so that the security of communication between the free packet device 20 and the information management system 30 can be ensured.
Fig. 3 is a schematic diagram of a data transmission apparatus according to an embodiment of the present application. As shown in fig. 3, the data transmission apparatus 10 includes a conversion module 14, the conversion module 14 includes a first interface 141 and a second interface 142, and the first interface 141 and the second interface 142 are different types of hardware interfaces. The conversion module 14 can be connected to the interface module 12 via a first interface 141 and to the free message device 20 via a second interface 142. The translation module 14 may transmit communication data between the interface module 12 and the free messaging device 20.
One interface module 12 can be connected to a plurality of free message devices 20, and when a plurality of free message devices 20 connected to the same interface module 12 have different interfaces, some of the free message devices 20 cannot be directly connected to the interface module 12, and at this time, the free message devices 20 are connected to the interface module 12 through the conversion module 14. The first interface 141 of the conversion module 14 has the same interface type as the interface module 12, and the second interface 142 of the conversion module 14 has the same interface type as the free message device 20, so that the free message device 20 can be connected to the interface module 12 via the conversion module 14, and the conversion module 14 forwards communication data between the free message device 20 and the interface module 12.
In the embodiment of the present application, the free message devices 20 with different interfaces can be connected to the same interface module 12 through the conversion module 14, so that communication between multiple free message devices 20 and the information management system 30 can be realized through one data transmission device 10, and communication between the free message devices 20 with different interfaces and the information management system 30 can be realized through the same data transmission device 10, which improves the applicability of the data transmission device 10, and can reduce the number of data transmission devices 10 required for communication between the free message devices 20 and the information management system 30, and reduce the cost for communication between the free message devices 20 and the information management system 30.
In one possible implementation, the first interface 141 of the conversion module 14 may be an RS-485 interface, and the second interface 142 of the conversion module 14 may be an RS-232 interface.
The first interface of the conversion module 14 is an RS-485 interface, the second interface of the conversion module 14 is an RS-232 interface, and the interface module 12 includes an RS-485 interface. If the interface of the free message device 20 is an RS-485 interface, the free message device 20 can be directly connected to the interface module 14. If the interface of the free message device 20 is the RS-232 interface, the interface of the free message device 20 is connected to the second interface 142 of the conversion module 14, and the first interface 141 of the conversion module 14 is connected to the interface module 12.
In the embodiment of the present application, since the RS-485 interface and the RS-232 interface are commonly used interfaces of the free message device 20, the first interface and the second interface of the conversion module 14 are the RS-485 interface and the RS-232 interface, respectively, the interface module 12 includes the RS-485 interface, and the interface module 12, in cooperation with the conversion module 14, can be compatible with most of the free message devices 20, thereby implementing communication between the free message device 20 and the information management system 30, and ensuring the applicability of the data transmission apparatus 10.
In one possible implementation, each interface module 12 may be connected to one or more free message devices 20 if the free message devices 20 have address information. If the free message device 20 does not have address information, each interface module 12 is connected to one free message device 20.
Since the information management system 30 will communicate with multiple free messaging devices 20, the information management system 30 needs to determine the data sent by each free messaging device 20 for this purpose. If the free message device 20 has address information, the data sent by the free message device 20 to the information management system 30 may carry the address information, and the information management system 30 may determine which free message device 20 sends the data according to the address information, and at this time, the same interface module 12 may connect a plurality of free message devices 20. If the free message device 20 does not have address information, each interface module 12 is connected to one free message device 20, and one data transmission apparatus 10 is connected to only one free message device 20, the information management system 30 distinguishes different free message devices 20 according to the identification of the data transmission apparatus 10.
In the embodiment of the present application, for the free message device 20 with address information, one data transmission apparatus 10 can implement communication between multiple free message devices 20 and the information management system 30, so as to reduce the required amount of the free message device 20, and thus, the cost for communication between the free message device 20 and the information management system 30 can be reduced. For the free message devices 20 without address information, each free message device 20 communicates with the information management system 30 through one data transmission apparatus 10, and the information management system 30 can distinguish different free message devices 20 through the identification of the data transmission apparatus 10, so that the communication between a plurality of free message devices 20 without address information and the information management system 30 can be realized, and therefore, the data transmission apparatus 10 has strong applicability.

The power supply module 15 is connected to the fourth interface 122 and the at least one fifth interface 123, respectively.
