Description

The processing system for controlling the terminal equipment of the Internet of Things and the gateway used in the Internet of Things

A processing system for controlling devices of the Internet of Things, particularly related to a processing system for controlling terminal devices of the Internet of Things and a gateway applied in the Internet of Things.

With the rapid development of the Internet of Things (IoT), the development of big data (Big data) and artificial intelligence (AI) has also been driven one after another. In order to achieve data collection, the primary focus is the networking of terminal equipment. For the current new terminal equipment, the networking function is already a built-in basic function. But for traditional terminal equipment, the traditional terminal equipment only provides a fixed communication interface and protocol, and the used communication protocol is not compatible with the current Ethernet transmission. Therefore, the current practice is to use the signal conversion of the bridge device, so that the traditional terminal equipment can achieve the purpose of signal transmission through the Ethernet network.

In addition to the low-level terminal equipment that needs to implement Ethernet support, the upper-level cloud platform also has other problems. For the cloud platforms of major manufacturers, the cloud platform cannot directly control the access of traditional underlying devices. Therefore, the cloud platforms of major manufacturers can only control specific terminal devices, but cannot achieve access control of various terminal devices.

Although traditional terminal equipment can convert the electrical signal into an Ethernet packet through the signal conversion of the bridge device. But if all terminal devices are connected to the cloud platform, it will cause communication congestion. This is because traditional terminal devices mostly use non-instant communication protocols or control methods. For example: the polling mechanism will visit all devices. When a terminal device receives a control command, other terminal devices will stop accepting the command until the aforementioned terminal device completes the command. Although this approach ensures the complete execution of control commands, this approach will cause other bridge devices and terminal devices to be suspended under the framework of the Ethernet network.

This model provides an out-of-band external control device, which is applied to independent monitoring The operating status of the sub-equipment and the remote booting of the electronic equipment.

The processing system for controlling the terminal equipment of the Internet of Things of the present invention is characterized by accessing the terminal equipment in the Internet of Things and generating corresponding output reports. The processing system that controls the terminal equipment of the Internet of Things includes: terminal equipment, heterogeneous bridging equipment, gateways and cloud servers. The heterogeneous bridge device has a first network interface and a communication interface. The communication interface is electrically connected to the terminal device. The heterogeneous bridge device converts the signal of the terminal device into a first network message; the cloud server has a data access interface and a data access interface The first virtual device is determined according to the device selection requirements. The data access interface generates the device status report of the first virtual device based on the second network information; the gateway has a second network interface, a processing module and an enumeration module, and the second The network interface is connected to the heterogeneous bridge device and the cloud server, the enumerating module generates the virtual interface and the second virtual device, the processing module maps the virtual interface to the communication interface, and the processing module maps the second virtual device to the terminal device , The processing module converts the first network message into the second network message according to the second virtual device.

The present invention also provides a gateway applied in the Internet of Things, which includes: a network interface, an enumeration module, and a processing module. Network interface, the network is connected to the cloud server, heterogeneous bridge equipment and computing equipment, the network interface transmits the first network information and the second network information, and the network interface receives communication interface setting requirements and equipment generation requirements; Module, enumerate the module to generate virtual interface and virtual device, enumerate the module to select the type of virtual interface according to the communication interface setting requirements, enumerate the module to determine the virtual device according to the device generation request; processing module, connect to the network interface and enumerate the module Group, the processing module maps the virtual device to the terminal device, and the processing module converts the first network message into the second network message according to the second virtual device.

Please refer to Figure 1, which is a schematic diagram of a processing system for controlling the IoT terminal device 110 of the new type. The processing system 100 for controlling IoT terminal devices of the present invention includes a terminal device 110, a heterogeneous bridge device 120, a gateway 130, a cloud server 140, and a computing device 150. The gateway 130 is connected to at least one heterogeneous bridge device 120, the cloud server 140, and the computing device 150 via a network. The terminal device 110 can receive a control command from the heterogeneous bridge device 120 or send an output result to the heterogeneous bridge device 120.

The heterogeneous bridge device 120 has a first network interface 121 and a communication interface 122. The heterogeneous bridging device 120 transmits network information through the first network interface 121 and the gateway 130. The heterogeneous bridge device 120 is electrically connected to the terminal device 110 through the communication interface 122. The heterogeneous bridging device 120 has at least one communication interface 122, and the communication interface 122 is connected to the terminal device 110. The type of the communication interface 122 can be, but is not limited to, an analog input/output interface (Analog I/O), a digital input/output interface (Digital I/O) or a universal asynchronous receiver/transmitter transmission interface (Universal Asynchronous Receiver/Transmitter, UART) The combination.

The heterogeneous bridging device 120 converts the received result signal into a first network message, and the first network message is compatible with the Ethernet transmission protocol (Ethernet). The heterogeneous bridge device 120 transmits the first network message through the first network interface 121. In addition, the heterogeneous bridge device 120 also converts the received first network message into a control command corresponding to the terminal device 110. Terminal set The type of the device 110 corresponds to the communication interface 122 of the connected heterogeneous bridge device 120. In other words, the communication interface 122 determines the terminal device 110 to which the heterogeneous bridge device 120 can be connected.

The cloud server 140 has a third network interface 141, a computing module 142, and a storage module 143. The computing module 142 is electrically connected to the third network interface 141 and the storage module 143. The storage module 143 records the data access interface 144. The data access interface 144 receives a second network message from the gateway 130, and the data access interface 144 is used to generate a device status report based on the second network message. The computing device 150 can be connected to the cloud server 140 via a network, and the corresponding heterogeneous bridge device 120 and the corresponding virtual device in the data access interface 144 can be set. Here, the virtual device set by the data access interface 144 is defined as the first virtual device 145.

The gateway 130 has a second network interface 131, a processing module 132 and an enumeration module 133. The processing module 132 is electrically connected to the second network interface 131 and the enumeration module 133. The second network interface 131 is connected to the computing device 150, the heterogeneous bridge device 120 and the cloud server 140 via a network. The gateway 130 transmits the aforementioned network packet to the heterogeneous bridge device 120 or the cloud server 140 through the second network interface 131. The enumeration module 133 determines the type of the corresponding virtual interface 134 and the type of the second virtual device 135 according to the request issued by the computing device 150.

The computing device 150 may be, but is not limited to, a personal computer (PC), a notebook computer (notebook), a mobile phone, or a tablet computer (tablet). The computing device 150 is used to send a communication interface setting request and a device generation request to the gateway 130 so that the gateway 130 generates the corresponding virtual interface 134 and the second virtual device 135. The computing device 150 further sends a device selection request of the first virtual device 145 to the cloud server 140 so that the data access interface 144 creates the first virtual device 145. The computing device 150 connecting the cloud server 140 and the gateway 130 may be the same device or two different computing devices 150.

The processing module 132 is used to run the agent program 136, and the agent program 136 is used to identify the model of the heterogeneous bridge device 120 and the type list of the terminal device 110. The type of the first virtual device 145 may not necessarily be the same as that of the second virtual device 135. In general, the user can set the first virtual device 145 and the second virtual device 135 to be devices of the same model. When the first virtual device 145 of the correct model cannot be selected, the first virtual device 145 compatible with the second virtual device 135 can be selected.

To further illustrate this new model for interface enumeration and equipment object processing and output Please cooperate with the process of the status report of each device as shown in Figure 2A. The processing method for controlling the IoT terminal device 110 of the present invention includes the following steps: Step S210: Connect the gateway network to the cloud server and the heterogeneous bridge device Step S220: The computing device sends a device selection request to the cloud server to generate a first virtual device; Step S230: The gateway generates a virtual interface according to the communication interface setting request, and the virtual interface is mapped to the heterogeneous bridge device First communication interface; step S240: the gateway generates a second virtual device according to the device generation requirements; step S250: maps the second virtual device to the first virtual device, so that the signal of the second virtual device is transmitted to the first virtual device; Step S260: The gateway receives the first network message through the virtual interface and converts the first network message into a second network message; Step S270: Send the second network message to the cloud server; and Step S280: The cloud server generates a device status report according to the second network message.

The first is the setting process of the gateway 130 and the cloud server 140. The computing device 150 is connected to the gateway 130 and the cloud server 140 via a network. For the setting of the cloud server 140, the computing device 150 needs to set the type of the first virtual device 145 to the data access interface 144 so that the data access interface 144 can directly access the data content of the second network message. In other words, the operating status of the first virtual device 145 displayed on the data access interface 144 is determined according to the content of the second network message. The data access interface 144 generates a corresponding device status report based on each first virtual device 145.

Then, the user configures the operating environment of the gateway 130 through the computing device 150. The computing device 150 sends a communication interface setting request and a device generation request to the gateway 130, please refer to Figure 2B. After the gateway 130 receives the communication interface setting request, the enumeration module 133 generates the corresponding virtual interface 134 and the second virtual device 135. After the computing device 150 is connected to the gateway 130 via a network, the gateway 130 can provide each connected heterogeneous bridging device 120. Each heterogeneous bridging device 120 also has its own communication interface 122. Therefore, the user can obtain the model of each heterogeneous bridge device 120 through the gateway 130, and then set the corresponding Type of communication interface 122.

The gateway 130 and the connected heterogeneous bridge device 120 can be listed on the display screen of the computing device 150, as shown in FIG. 3A. The gateway 130 in FIG. 3A is the gateway A and the gateway B, respectively. Gateway A connects two heterogeneous bridge devices, namely heterogeneous bridge device I and heterogeneous bridge device II. The heterogeneous bridging device 1 is further connected to three terminal devices 110. The gateway B is connected to a heterogeneous bridging device 120, which is a heterogeneous bridging device III. The heterogeneous bridge device III is connected to a terminal device 110. The user can select any heterogeneous bridging device 120 in Figure 3A. In FIG. 3B, the black thick dashed frame is used as the selected heterogeneous bridging device 120. The computing device 150 lists the type and quantity of the corresponding communication interface 122 according to the model information fed back by the heterogeneous bridge device 120, as shown in FIG. 3B. After the user selects the communication interface 122, the gateway 130 will define the selected communication interface 122 as the virtual interface 134, so that the gateway 130 communicates with the heterogeneous bridge device 120 in a communication protocol that complies with the virtual interface 134.

After completing the setting of the virtual interface 134, the agent program 136 will list the corresponding terminal device 110 according to the selected virtual interface 134. For example, when the user selects RS-232 as the virtual interface 134, the agent program 136 will select a list of compatible terminal devices 110 according to RS-232. After the user selects the terminal device 110 from the list, the agent program 136 defines the selected device as the second virtual device 135. The agent program 136 encapsulates the second virtual device 135 as a device generation request and sends it to the gateway 130. While selecting the second virtual device 135, the gateway 130 will load the corresponding attributes and operation model of the second virtual device 135. Wherein, the operation attributes and models are generated according to the operation mode of the terminal device 110.

For example: the conversion processing of electrical signals to temperature and humidity, or the trigger types of digital signals, etc. The gateway 130 will map to the communication interface 122 of the heterogeneous bridging device 120 according to the virtual interface 134. Wherein, the mapping action method is to encapsulate the transmission content of the communication interface 122 through the communication protocol of the Ethernet, and enable the gateway 130 to communicate with the terminal device 110 connected to the heterogeneous bridging device 120.

The main function of the cloud server 140 is to provide a report output of the real-time status and history information of the terminal device 110. The data access interface 144 of the cloud server 140 can not only provide the computing device 150 with the settings of the first virtual device 145, but also can map the connection between the first virtual device 145 and the terminal device 110. The mapping connection is to connect the terminal equipment 110, The second virtual device 135 and the first virtual device 145 are connected in series, so that the electrical signal sent by the terminal device 110 can be converted into the data data of the first virtual device 145 through the gateway 130. In other words, the gateway 130 converts the first network message into data conforming to the terminal device 110 according to the virtual interface 134, so that the data access interface 144 displays the operation of the corresponding first virtual device 145 (corresponding terminal device 110) Status and value.

In the present invention, connecting the heterogeneous bridge device 120 through the gateway 130 can reduce the burden of connection and transmission between the cloud server 140 and the terminal device 110. Since most of the current transmission protocols used by the terminal device 110 are general training protocols for asynchronous transmission, the input and output processing will occupy most of the server's resources. Coupled with the non-immediate response of the terminal device 110, the server needs to spend time waiting for a response when processing the input/output of the terminal device 110. Through the control of the heterogeneous bridging device 120 by the gateway 130 of the present invention, the operating load of the terminal device 110 by the cloud server 140 can be distributed to the gateway 130, so that the cloud server 140 can control the task dispatching of the terminal device 110 .

In addition to the aforementioned information transmission from the terminal device 110 to the cloud server 140, in the present invention, the cloud server 140 can also send control commands to the terminal device 110 to drive the terminal device 110 to operate and report the operation result. After the cloud server 140 sends the control command to the terminal device 110, the cloud server 140 converts the control command into a second network message and sends it to the gateway 130. The gateway 130 translates and identifies the terminal device 110 corresponding to the control command according to the second network message, and repackages the second network message into the first network message. The gateway 130 sends the first network message to the corresponding heterogeneous bridge device 120 and the terminal device 110. The heterogeneous bridging device 120 translates the first network message into a control command, and sends the control command to the terminal device 110.

In order to clearly illustrate the operation process of the present invention, two terminal devices 110 are taken as an example below. The two terminal devices 110 are defined as a first device 221 (assumed as a temperature sensor) and a second device 222 (assumed as an optical alarm). The communication interface of the first device 221 is an AI interface (Analog input), and the first device 221 is an AI interface (Analog input). The communication interface of the second device 222 is a DI interface (Digital input). The gateway 130 connects two heterogeneous bridge devices 120, a computing device 150 and a cloud server 140, as shown in FIG. 4.

First, the computing device 150 sends a communication interface setting request and a device generation request to the gateway 130, so as to set the virtual interface 134 and the virtual device of the gateway 130. Please refer to Exam as shown in Figure 2C. Since the gateway 130 is connected to two heterogeneous bridge devices 120, the gateway 130 will generate the first virtual interface 211 and the second virtual interface 212. The first virtual interface 211 is mapped to the AI interface of the first device 221, and the second virtual interface 212 is mapped to the DIO interface of the second device 222. The gateway 130 will set the first virtual interface 211 to map to connect to the first device 221, and the second virtual interface 212 to map to connect to the second device 222. The arrow indicates that the first device 221 is mapped to the first virtual interface through the aforementioned element, and the arrow indicates that the second device 222 is mapped to the second virtual interface through the aforementioned element. The gray part in FIG. 4 is represented as the second virtual interface 212, and the second virtual interface 212 is used to represent the heterogeneous bridging device 120 and the communication interface 122 to which the gateway 130 is mapped and connected.

Next, the computing device 150 sends a device generation request to the gateway 130, so that the gateway 130 generates two sets of virtual devices. Here, the two sets of virtual devices generated by the gateway 130 are respectively defined as the first simulation device and the second simulation device. The first simulation device is generated according to the first virtual interface 211, and the first simulation device will correspond to the first device 221. The second simulation device is generated according to the second virtual interface 212, and the second simulation device will correspond to the second device 222. The first analog device can obtain the electrical signal of the first device 221 through the first virtual interface 211. The gateway 130 converts the electrical signal of the first device 221 into a data signal, and encapsulates the data signal into a second network message.

The computing device 150 sends a device selection request to the cloud server 140, and the type of virtual device can be selected in the data access interface 144. As shown in Figure 5, the user selects a virtual temperature sensing device in the data access interface 144 through the computing device 150, and maps the virtual temperature sensing device to the first analog device. In Figure 5, the devices listed in the gateway 130 are used as the source options for the mapping.

It is assumed here that the electrical measurement range of the first device 221 is 4-20 mA, and the corresponding temperature range is 0-100°C. Therefore, the gateway will establish a related conversion function library for the first device 221, please refer to the following formula: temperature T=6.25* AI-25 formula 1

AI is the electrical signal value measured by the first device 221

Therefore, when the AI value measured by the first device 221 is 8.5 mA, the first analog device obtains a temperature of 28.125° C. according to the electrical signal value of the AI. The gateway 130 is packaged according to the temperature value It is the second network message and sent to the cloud server 140. Therefore, the virtual temperature sensing device will obtain the temperature value of 28.125°C, and the user can see the temperature of 28.125°C through the data access interface 144 instead of the AI value of 8.5mA.

The gateway 130 performs the following setting processing for the second device 222 of the DIO interface. The computing device 150 causes the gateway 130 to generate the second virtual interface 212 and the second simulation device. When the second simulation device is selected, the gateway 130 will also load the related operation model of the second device 222. For example, the second device 222 is a device with 4 sets of DI inputs. Therefore, the second device 222 will send different first network messages to the gateway 130 according to different trigger conditions. For example, the second device 222 may send a combination of the following electrical signals: "0000", "0100", "1010" or "1111". When the second simulation device is selected, the gateway 130 also loads the operation model of the second device 222 at the same time. In this case, various electrical signal combinations of the second device 222 respectively represent different detection states.

After the gateway 130 receives the first network message from the second device 222, the gateway 130 will generate a corresponding output signal according to the second simulation device and the operation model. The gateway 130 encapsulates the output signal as a second network message and sends it to the cloud server 140. A set of virtual devices of the electronic fence are set in the data access interface 144 for mapping and connecting to the second analog device. After the data access interface 144 receives the second network message, the data access interface 144 displays the corresponding alarm status according to the second network message. Therefore, the user can observe the current operating status of the virtual temperature sensing device (corresponding to the first device 221) and the electronic fence (corresponding to the second device 222) on the data access interface 144.

The processing system and method for controlling the Internet of Things terminal device 110 and the gateway 130 applied in the Internet of Things of the present invention can access the terminal device 110 in the Internet of Things and generate corresponding output reports, and pass the analysis of the gateway 130. Layer management enables the load of the cloud server 140 to be effectively reduced. In addition, through the respective settings of the first virtual device 145 and the second virtual device 135, the mapping connection between the terminal device 110 and the first virtual device 145 can be more flexibly assigned.

Although the present invention is disclosed in the foregoing preferred embodiments as above, it is not intended to limit the present invention. Anyone who is familiar with similar skills can make some changes and modifications without departing from the spirit and scope of the present invention.
