Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
Prior to the detailed description of the present application, related technical content will be described.
In a computer system, a common path for information to be transferred between components is called a bus, and a microcomputer connects the functional components in a bus structure. The bus is an internal structure, it is a public channel for CPU (Central Processing Unit ), internal memory and input/output equipment to transfer information, all the components of the host are connected by means of bus, and the external equipment is connected with bus by means of correspondent interface circuit so as to form the computer hardware system. Physically, the bus is a wire harness connected to a motherboard or copper foil conductors on a PCB (Printed Circuit Board ) board, the transmission medium of which is a metal cable.
Soft buses, as their name implies, are a technology that utilizes software technology, based on commonly used physical link protocols, to implement bus capabilities. In physical form, the soft bus can be divided into two types, one type is wireless transmission through electromagnetic waves, no actual physical wires exist, and the physical layer mainly takes WIFI and Bluetooth protocols as main materials; the other is to use the application transmission line of the equipment level for wired transmission, and the physical layer is mainly based on the Ethernet protocol.
The technical characteristics of open source hong-Mongolian OpenHarmony are mainly that hardware interaction and resource sharing can be realized among various devices; mainly depends on application technologies such as distributed soft buses, distributed device virtualization, distributed data management, distributed task scheduling and the like. Referring to fig. 1, fig. 1 is a distributed soft bus service model, and a distributed soft bus is a communication base of all distributed applications. The distributed soft bus logically abstracts distributed communications into a business model consisting of four parts: discovery, connection, networking, and transport. The four parts work separately in the whole soft bus business logic, and the goal of distributed soft bus communication is achieved by constructing a distributed communication framework.
The physical layer communication protocol adopted by the existing soft bus technology is mainly WIFI and Bluetooth technologies. Limited by the communication protocol, the effective transmission distance is only 100 meters, and the effective transmission distance is only about 300 meters under ideal environment. Such short distances, in practical applications, greatly limit the effective coverage of a local master terminal device (also called a superterminal device) based on soft bus technology. And thus its application is limited to small-scale scenes in homes, offices, etc.
In practical applications in other industries, the communication distance between terminal devices involved in the fields of highway traffic, tunnel construction, park management, railway dispatching, wharf ports, factories, agricultural cultivation and the like is often more than 500 meters, and some are even several kilometers. The existing soft bus technology is far from being satisfied.
In the embodiment of the application, a first main terminal device belonging to a first area sends first data to a second main terminal device belonging to a second area based on a wireless transmission mode; and the first main terminal equipment belonging to the first area receives second data sent by the second main terminal equipment belonging to the second area based on the wireless transmission mode. Compared with the prior art that the main terminal equipment can only communicate with the surrounding terminal equipment in the area to which the soft bus belongs, in the embodiment of the application, as the main terminal equipment in two different areas can establish connection with the surrounding terminal equipment respectively for communication in the respective areas, the main terminal equipment in two different areas can also mutually perform data transmission based on a wireless transmission mode, so that the data transmission range is not limited in one area any more, but can extend to other areas outside the area, therefore, the effective transmission distance of the soft bus technology can be enlarged, and the practical application of the soft bus technology in other industries needing far effective data transmission can be enlarged; in addition, the effective transmission distance is enlarged based on a wireless transmission mode, so that the cable cost caused by the wire can be avoided.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 2, fig. 2 is a schematic flow chart of an embodiment of a data transmission method of the present application, where the method of the embodiment of the present application is applied to a first master terminal device, and the first master terminal device belongs to a terminal device in a first area capable of simultaneously establishing a connection with a plurality of first peripheral terminal devices through a soft bus.
The method comprises the following steps: step S101 and step S102.
Step S101: and sending the first data to a second main terminal device based on a wireless transmission mode, wherein the second main terminal device belongs to a terminal device which can simultaneously establish connection with a plurality of second surrounding terminal devices through a soft bus in a second area.
Step S102: and receiving second data sent by the second main terminal equipment based on the wireless transmission mode.
In this embodiment of the present invention, the first main terminal device is a main terminal device in a first area, and the first main terminal device may establish connection with a plurality of first peripheral terminal devices around in the first area through a soft bus, so that the first main terminal device may communicate with the plurality of first peripheral terminal devices in the first area, and an effective transmission distance of the communication of the first main terminal device is in the first area. The second main terminal device is a main terminal device of the second area, and the second main terminal device can establish connection with a plurality of second surrounding terminal devices around the second area through the soft bus at the same time, so that the second main terminal device can communicate with the plurality of second surrounding terminal devices in the second area, and the effective transmission distance of the communication of the second main terminal device is in the second area.
The wireless transmission scheme (Wireless transmission) is a scheme for transmitting data by using a wireless technology. The wireless transmission mode and the wired transmission mode are corresponding. In the embodiment of the present application, the conditions that the wireless transmission mode needs to satisfy are: the first main terminal device of the first area and the second main terminal device of the second area can communicate with each other. And thus a relatively long-range wireless transmission scheme can be employed. For example: LR-WiFi (Long range WiFi), wireless bridges, etc. may be used. A more common remote wireless transmission method at present uses a wireless bridge.
The first main terminal equipment of the first area can send first data to the second main terminal equipment of the second area based on a wireless transmission mode, and can also receive second data sent by the second main terminal equipment of the second area, so that the effective transmission distance of the first main terminal equipment communication is not limited in the first area but is expanded to the second area, and the effective transmission distance of the second main terminal equipment communication is not limited in the second area but is expanded to the first area.

Compared with the prior art that the main terminal equipment can only communicate with the surrounding terminal equipment in the area to which the soft bus belongs, in the embodiment of the application, as the main terminal equipment in two different areas can establish connection with the surrounding terminal equipment respectively for communication in the respective areas, the main terminal equipment in two different areas can also mutually perform data transmission based on a wireless transmission mode, so that the data transmission range is not limited in one area any more, but can extend to other areas outside the area, therefore, the effective transmission distance of the soft bus technology can be enlarged, and the practical application of the soft bus technology in other industries needing far effective data transmission can be enlarged; in addition, the effective transmission distance is enlarged based on a wireless transmission mode, so that the cable cost caused by the wire can be avoided.

That is, the first main terminal device itself is integrated with the first wireless transmission part, the second main terminal device itself is integrated with the second wireless transmission part, and the first wireless transmission part and the second wireless transmission part can ensure that the first main terminal device and the second main terminal device communicate with each other, and at this time, the wireless transmission path based on the wireless transmission mode is: a first wireless transmission part of the first main terminal equipment and a second wireless transmission part of the second main terminal equipment. The wireless transmission component may be a component capable of implementing a relatively long-distance wireless transmission mode, including but not limited to LR-WiFi, a wireless network bridge, a long-distance wireless radio frequency module, and the like.
By the method, the wireless communication capacity of the main terminal equipment can be improved on the basis of the existing main terminal equipment, so that the main terminal equipment in two different areas can directly communicate, and the deployment of additional wireless communication equipment is avoided.
The method and the device are applicable to the application scenario that the first wireless transmission component and the second wireless transmission component can ensure that the first main terminal device and the second main terminal device are mutually communicated in the distance range between the two areas, and the wireless communication device does not need to be deployed additionally.
In some embodiments, within the master terminal device (first master terminal device, second master terminal device), the wireless transmission means (first wireless transmission means, second wireless transmission means) may employ WIFI universal communication protocol at the physical layer.
In some embodiments, the wireless transmission means may be a wireless bridge, i.e. the first master terminal device comprises a terminal device integrated with a first wireless bridge and the second master terminal device comprises a terminal device integrated with a second wireless bridge.
In some embodiments, step S101, the sending, by the first wireless transmission unit, the first data to the second wireless transmission unit may further include: step S101B; at this time, step S102, where the receiving, based on the wireless transmission manner, the second data sent by the second master terminal device may include: step S102B, as shown in FIG. 4.
