Description

BACKGROUND

The present embodiments generally relate to a system for data communication in a network between two or more local devices and a cloud computing platform, in which data collected and/or stored on at least one local device are transmitted to a cloud computing platform.

There is an increasing trend of industrial automation systems, assets, machines, sensors, mobile devices, etc. in all fields of the industrial production, energy, transportation, and in other areas such as banking, retail, hospitality, and medical health care systems being connected via network connections to the Industrial Internet of Things (IIoT) directly or via cloud gateways. Data analytics (e.g., data mining, deep learning, artificial intelligence) is a core aspect in this whole area of connected things and generates a new level of knowledge and usability. According to statistical predictions, about 50 billion interconnected devices are forecast for 2020 worldwide. This corresponds to about 6.5 interconnected devices per person. However, all these different devices communicate with each other using different formats and protocols.

In systems based on cloud computing technology, a large number of devices is connected to a cloud computing system via the Internet. The devices may be located in a remote facility connected to the cloud computing system. For example, the devices may include, or consist of, equipment, sensors, actuators, robots, and/or machinery in an industrial set-up(s). The devices may be medical devices and equipment in a healthcare unit. The devices may be home appliances or office appliances in a residential/commercial establishment.

The cloud computing system may enable remote configuring, monitoring, controlling, and maintaining connected devices (e.g., ‘assets’). Also, the cloud computing system may facilitate storing large amounts of data periodically gathered from the devices, analyzing the large amounts of data, and providing insights (e.g., Key Performance Indicators, Outliers) and alerts to operators, field engineers, or owners of the devices via a graphical user interface (e.g., of web applications). The insights and alerts may enable controlling and maintaining the devices, leading to efficient and fail-safe operation of the devices. The cloud computing system may also enable modifying parameters associated with the devices and issues control commands via the graphical user interface based on the insights and alerts.

The cloud computing system may include a plurality of servers or processors (e.g., ‘cloud infrastructure’) that are geographically distributed and connected with each other via a network. A dedicated platform (hereinafter referred to as ‘cloud computing platform’) is installed on the servers/processors for providing above functionality as a service (hereinafter referred to as ‘cloud service’). The cloud computing platform may include a plurality of software programs executed on one or more servers or processors of the cloud computing system to enable delivery of the requested service to the devices and users of the devices.

One or more application programming interfaces (APIs) are deployed in the cloud computing system to deliver various cloud services to the users.

The communication between the IIoT devices may be performed at the edge of the IIoT devices, the IIoT gateways, or the cloud computing platform as the central computing infrastructure. If communication between IIoT devices is performed at the edge of the local IIoT devices itself, the IIoT devices are to be able to understand each other, which provides that the IIoT devices communicate by the language and protocols.

However, most of the IIoT devices use different protocols and data formats so that a direct communication between the devices is often not possible. Therefore, a communication between two devices is only possible if the two devices support the same protocols, respectively. Only a small part of devices may support all available protocols, which has various reasons. Many devices do not have enough memory capacity or computer performance to support different protocols, so that currently, many devices cannot communicate with each other.

DETAILED DESCRIPTION

In the following description, for purposes of explanation and not limitation, specific details are set forth in order to provide a thorough understanding of the present embodiments. It will be apparent to one skilled in the art that the present embodiments may be practiced in other implementations that depart from these specific details.

FIG. 1 provides a general overview of one embodiment of a system 100 for communication between a number of local devices 110, 120, 130 in a network of a cloud computing platform 150. The local devices 110, 120, 130 may be part of an industrial plant. Additional local devices (LD) may be added to the system 100. Examples of local devices are acceleration sensors to capture rotational and vibration data of an actuator, which helps in early detection of various failure modes encountered in rotation mechanical equipment. Other examples are medical devices in a healthcare environment or light and temperature sensors in a smart building or pressure sensors in the automotive area.

The devices 110, 120, 130 include, respectively, an IIoT agent 112, 122, and 132 and are connected to an IIoT gateway 140, which is connected by a network to an IIoT cloud computing platform 150. The network may include one or more wide area networks (WAN), such as Internet, local area networks (LAN), or other networks that may facilitate data communication.

If two or more devices 110, 120, 130 want to communicate directly with each other but do not have the same languages/formats in common the two or more devices 110, 120, 130 may use the service of a translator module 170 located in the cloud computing platform 150. The translator module 170 includes a processor 180 and other hardware components and a software application 190.

The device 110 may communicate with other devices using corresponding formats/protocols a₁, a₂, . . . , a_n. The device 120 may communicate to other devices using corresponding formats/protocols b₁, b₂, . . . , b_n. The device 130 may communicate to other devices using corresponding formats/protocols i₁, i₂, . . . , i_n. However, if the protocols a₁, a₂, . . . , a_n implemented in the first device 110 are not the same as the protocols b₁, b₂, . . . , b_n implemented in the second device 120, it is not possible for the devices 110, 120, 130 to communicate directly with each other. Therefore, the first device 110 and the second device 120 send the data that the first device 110 and the second device 120 want to communicate to the other device via the gateway 140 to the cloud computing platform 150. In the cloud computing platform 150, the translator module 170 translates (e.g., converts) at least one of the protocols a₁, a₂, . . . , a_n to at least one of the protocols b₁, b₂, . . . , b_n of the second device. For example, the protocol a₁ is translated a transformed to the protocol b₃: a₁ {circle around (7)} b₃

This provides that the translator module 170 is to understand at least one protocol/language/format that is understood (e.g., processable or executable) by the first device 110 and at least one protocol/language/format that is understood (e.g., processable or executable) by the second device 120. If the translator module 170 knows one of the protocols a₁, a₂, . . . , a_n of the first device and one of the protocols b₁, b₂, . . . , b_n of the second device, a communication between the two devices 110, 120 may be performed. Therefore, the translator module 170 does not need or need to be able to process all protocols of the two devices, but is to be able to process at least one protocol from the first device 110 that may be translated or converted to at least one protocol of the other device 120. The protocol conversion may be performed in real time. Further, the protocol conversion may be logged for further analyzing the system.

Devices or systems that were not enabled to communicate with each other before may now communicate by an indirect communication by a third party (e.g., translator module 170) and therefore exchange data. By using this indirect communication, more devices or systems may communicate with each other.

Further, if for the communication of the local devices 110, 120, 130 the cloud computing platform 150 is used, a higher level of security for sensitive data may be provided, as the IIoT platform 150 may include a database regarding permission levels which devices are allowed to communicate with each other. Further, as the cloud computing platform may provide higher calculating speed and more memory space, the quality of the communication is higher and faster.

The local devices may be configured easier, as the local devices must not support many protocols originally. This saves design and developing expenditure as well as implementing expenditure, and therefore, costs. Further, the cloud computing platform 150 may include a number of other communication modules that may generate an automatic communication between specified local devices.

Therefore, according to the present embodiments, the software application 190 of the translator module 170 is configured to understand different protocols (e.g., capable of executing different protocols). The task of this software application 190 is to receive inquiries and to translate the inquiries into the required language or format. In a further embodiment, the software application 190 may include a second software application or may transmit the inquiry to a second application that may understand and process the language and is able to translate. The data transferred to or transformed into another communication protocol are submitted again directly to the local device 120 that is to be the receiver of the data message.

The translation algorithm (A) of the software application 190 may include sub-algorithms (SA1, SA2, . . . SAn) that are executable in a serial and/or parallel sequence. Further, a workflow regarding the sequence and the location of the execution of the sub-algorithms (SA1, SA2, . . . SAn) may be controlled by a further software application.

The translation algorithm (A) may be configured as a clustering and/or an artificial neural network and/or a support vector machines and/or subdivided into sub-algorithms (SA1, SA2, . . . SAn).

According to the present embodiments, devices of different manufacturers may communicate with each other. Complexity reduction may be achieved, as it is no longer necessary to support different protocols by one single local device. By using a third-party software application implemented in a cloud computing platform 150, different devices with different communication protocols may be connected to exchange data with each other.

Variously disclosed embodiments include data processing systems and methods that may be used to facilitate the translation of one communication protocol to another communication protocol. In one example, a system may include at least one processor configured via executable instructions included in at least one memory to initiate a plurality of translation tasks that are respectively executed by different processing resources. The translation tasks respectively manage respective subsets of communication protocols assigned to respective different local devices 110, 120, 130 to meet communication requirements. This also includes a determination if a communication between two local devices is to be performed with respect to security aspects.

Further, the network may be divided into sub-networks that allow access to all the other components connected to the network. The network may include an encryption scheme that may be employed over the public Internet. The network may be configured in a wired and/or wireless configuration that supports data transfer.

The displayed representation is intended to illustrate one possible configuration of the system 100. Other configurations may include fewer components, and in other configurations, additional modules may be utilized. These changes in configurations and components may increase or alter the capabilities of the system 100. Especially in the field of medical imaging, devices for capturing high-resolution medical images of a patient, such as magnetic resonance imaging (MRI) machines, computer tomography, x-ray, positron emission tomography, scanning microscopy, and ultrasound imaging systems, the sensors are configured to capture image data (e.g., sensors such as charged-coupled devices (CCD)). Further, other types of sensors such as acoustical, optical, piezoelectric, pressure, temperature, and chemical sensors may be used to collect additional data for a specific local device 110, 120, 130.

A cloud computing platform 150 according to a fourth aspect may be provided to perform the act S30, for example.

In act S40, the data is submitted with the other communication protocol (b₁, b₂, . . . , b_n) to the at least one second device 120.
