The memory chip 14 is used to provide temporary storage of data for the main control chip 12. The flash memory chip 16 is used for storing configuration data of the main control chip 12.
The main control chip 12 is an existing processor chip in the field, and may be any type of digital processor chip existing in the market, and the specific type may be determined according to an internet of things communication module required to be used in an actual application scenario. For example, the corresponding main control chip 12 may be purchased according to the number of the communication modules of the internet of things that need to be inserted into the MINI PCI-E interface socket 18 in the actual application scenario, the types of the interface protocols used by the communication modules of the internet of things, and the like, so that the adopted main control chip 12 can support multiple standard interface protocols, and the access and data transmission needs of different communication modules of the internet of things are met. It should be noted that the types of standard interface protocols that can be supported by different types of main control chips 12 are different, the number, types, and the like of the internet of things communication modules used in different application scenarios are also different, and the standard interface protocols adopted by different internet of things communication modules are different; therefore, only the main control chip 12 of the corresponding type needs to be selected according to the number and the type of the communication modules of the internet of things used in the actual application scenario, for example, but not limited to, the main control chip 12 supporting the main stream protocols such as the SPI interface, the serial port, and the USB interface is selected.

For example, the host chip 12, the memory chip 14 and the flash chip 16 may be disposed on the same PCB substrate, while the MINI PCI-E interface socket 18 is disposed on another PCB substrate as a communication module plug panel.

The cellular network backhaul module refers to a communication module that uses a cellular network to perform data transmission, but may be various cellular communication modules in the field. The specific number, types and the like of the internet-of-things communication module and the cellular network return module are determined by the network distribution requirements of the internet-of-things scene in practical application. The internet of things node data refers to internet of things data acquired by each internet of things terminal (or called node) deployed in an internet of things scene in real time or periodically.
Specifically, in an application scenario, the cellular network backhaul module and one or more internet of things communication modules of different communication systems to be used may be inserted into the MINI PCI-E interface socket 18 in the form of a plug-in card, and after the control circuit 100 of the entire internet of things gateway is powered on, the internet of things communication module wirelessly collects internet of things node data from each internet of things terminal in the application scenario, and outputs the internet of things node data to the main control chip 12 from the MINI PCI-E interface socket 18, so that the main control chip 12 performs corresponding conventional processing and aggregation on the received internet of things node data, and outputs the internet of things node data to the cellular network backhaul module from the MINI PCI-E interface socket 18, so that the cellular network backhaul module wirelessly transmits the data to an upper server to which the internet of things gateway belongs through the cellular network, and the upper server performs subsequent analysis processing.

According to the control circuit 100 of the internet of things gateway, through the combined design of the main control chip 12, the memory chip 14, the flash memory chip 16 and the MINI PCI-E interface socket 18, the internet of things communication module and the cellular network return module of the internet of things gateway can be plugged in the MINI PCI-E interface socket 18 respectively in a plug-in card mode, so that the control circuit of the internet of things gateway can be plugged in the internet of things communication modules of different communication systems (one or more types), and the data of the internet of things node can be returned to an upper-layer server through the cellular network, so that different application environments can be effectively adapted. The application is approved in remote areas or environments lacking a wired return network, and the application and the cellular network return module cooperate to realize the return of the node data of the Internet of things to an upper layer server. In the face of the Internet of things terminals with various communication modes, various Internet of things gateways do not need to be deployed, the network distribution cost is greatly saved, the energy consumption and the Internet of things upgrading cost are reduced, and the purpose of greatly reducing the application cost is achieved.
In one embodiment, the number of the MINI PCI-E interface sockets 18 may be two or more, and each MINI PCI-E interface socket 18 is electrically connected to the main control chip 12.
It can be understood that with the continuous popularization and development of the internet of things technology, the number of the internet of things terminals contained in the same scene is more and more, the types of the internet of things terminals are more and more diversified, and more internet of things communication modules are needed to be used for completing the collection of the internet of things node data collected by the internet of things terminals. Correspondingly, in the control circuit 100 of the internet of things gateway, the number of the MINI PCI-E interface sockets 18 that can be set may be more than 1, and specifically may be determined according to the number of the internet of things communication modules that need to be inserted in an actual application scenario. One MINI PCI-E interface jack 18 can support the insertion of multiple internet of things communication modules, however, after all, the number supported is limited. Therefore, by means of an extensible setting mode, the plurality of MINI PCI-E interface sockets 18 are arranged, plugging and unplugging of more Internet of things communication modules can be conveniently supported, the extension performance of the control circuit 100 of the Internet of things gateway is improved, and the applicability of the Internet of things gateway to which the control circuit 100 of the Internet of things gateway belongs is effectively improved.
Referring to fig. 2, in an embodiment, the control circuit 100 of the internet of things gateway further includes a POE power supply circuit 11, a first ethernet PHY chip 13, and a backhaul port socket 15. The POE power supply circuit 11 is electrically connected to the first ethernet PHY chip 13, the backhaul network port socket 15, and the main control chip 12, respectively. The first ethernet PHY chip 13 is electrically connected to the backhaul port socket 15 and the main control chip 12, respectively. The POE power supply circuit 11 is configured to supply power to the backhaul network port socket 15. The first ethernet PHY chip 13 is configured to output the internet of things node data output by the main control chip 12 to the backhaul port socket 15. The backhaul port jack 15 is used to connect an upper layer server through wan communication.
It can be understood that the POE power supply circuit 11 is an existing POE power supply module in the field, and may be any type of POE power supply module on the market, and specifically may be selected according to the power supply requirement of the backhaul network port socket 15. The first ethernet PHY chip 13 is an ethernet PHY chip commonly used in the art, and is used for implementing connection between the main control chip 12 and an ethernet. The backhaul port jack 15 is an ethernet port commonly used in the art. The first ethernet PHY chip 13, the backhaul port socket 15, and the POE power supply circuit 11 may be soldered to the same PCB substrate as the main control chip 12; the first ethernet PHY chip 13, the backhaul port socket 15, and the POE power supply circuit 11 may also be soldered on an independent PCB substrate, and the specific setting mode may be determined according to the actual application needs.
Specifically, in practical applications, when there is a fixed network backhaul network in an internet of things scene, the main control chip 12 may also connect to the wide area network through the first ethernet PHY chip 13, so as to perform corresponding conventional processing on the received internet of things node data, and transmit the data to the wide area network through the first ethernet PHY chip 13 and the backhaul socket 15, and transmit the data to the upper server through the wide area network. Therefore, the method can be complementary with a cellular network return module in practical application, and application coverage of more internet of things scenes is realized. For example, when there is no fixed network backhaul network in the scenario of the internet of things, and only there is a mobile data network (i.e., a cellular network), the main control chip 12 may transmit the processed data of the internet of things node back to the upper server through a cellular network backhaul module.
Through the extended design of the POE power supply circuit 11, the first ethernet PHY chip 13, the backhaul port socket 15 and the main control chip 12, efficient and highly reliable backhaul of the internet of things node data in different application environments can be realized, the environmental adaptability of the control circuit 100 of the internet of things gateway is improved, and the backhaul efficiency of the internet of things node data is improved.
Referring to fig. 3, in an embodiment, the control circuit 100 of the internet of things gateway further includes a second ethernet PHY chip 17 and a debug port socket 19. The second ethernet PHY chip 17 is electrically connected to the main control chip 12 and the debug port socket 19, respectively. The debugging network port socket 19 is used for connecting an upper layer server through wide area network communication. The second ethernet PHY chip 17 is configured to receive the debugging parameters sent by the upper layer server and output the debugging parameters to the main control chip 12.
It is understood that the second ethernet PHY chip 17 is an ethernet PHY chip commonly used in the art. The debug port socket 19 is an ethernet port commonly used in the art. The second ethernet PHY chip 17 and the debug port socket 19 may be soldered to the same PCB substrate as the main control chip 12; the second ethernet PHY chip 17 and the debug port socket 19 may also be soldered on an independent PCB substrate, for example, the second ethernet PHY chip 17, the backhaul port socket 15, and the POE power supply circuit 11 are soldered on the same PCB substrate, and the specific setting mode may be determined according to actual application requirements. The debugging parameters refer to test parameters determined by the upper layer server for different scenes of the internet of things, and are used for enabling the main control chip 12 to automatically complete initialization configuration, setting parameter change or performance test and the like for different scenes of the internet of things, and the debugging parameters can be specifically determined according to the debugging requirements of the upper layer server on the control circuit 100 of the gateway of the internet of things in practical application.
Specifically, in the practical application process, the main control chip 12 may also access the wide area network through the second ethernet PHY chip 17 and the debugging port socket 19, so as to receive debugging parameters issued by the upper server, so that the upper server may remotely debug the control circuit 100 of the internet of things gateway, so that the control circuit 100 of the internet of things gateway can be used in the internet of things scene for the first time, or when the original internet of things scene is transferred to another different internet of things scene for use, the debugging can be quickly completed to adapt to the currently used internet of things scene; the control circuit 100 of the internet of things gateway can be remotely controlled by the upper-layer server conveniently, and special debugging personnel do not need to be arranged to debug on site, so that the application cost is further saved.
In one embodiment, the main control chip 12 is an MCU or CPU.

In one embodiment, the memory chips 14 are DDR3 chips or DDR4 chips. It can be understood that in this embodiment, a commercially available DDR3 chip or DDR4 chip may be used as the memory required by the main control chip 12 during operation, and the specific specification may be selected according to the operation requirement of the main control chip 12. The DDR3 chip or the DDR4 chip has good performance, can efficiently support the temporary data storage requirement of the main control chip 12, improves the overall performance of the control circuit 100 of the Internet of things gateway, and reduces the failure rate of the control circuit 100 of the Internet of things gateway, thereby saving the maintenance cost and achieving the purpose of further reducing the application cost of the control circuit 100 of the Internet of things gateway.
