Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor belong to the protection scope of the utility model.

[0088] In the description of the utility model, it is necessary to explain that, unless there is explicit provision and limitation, the term '' set up '' '' connect '' '' connect '' should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, also can be direct connection, also can be indirect connection through intermediate medium, can be the intercommunication of two elements. For the ordinary skill in the art, the above-mentioned term in the utility model can be understood according to the specific meaning of the specific situation.

[0089] Embodiment 1:

[0090] The embodiment proposes a kind of multifunctional edge gateway, as shown in Figure 1 Including MPU module, Ethernet module, WiFi module, general acquisition module;

[0091] The Ethernet module is connected with the MPU module by RMII interface, and is connected with cloud platform port by internet;

[0092] The WiFi module is connected with the MPU module by first SDIO interface;

[0093] The general acquisition module is connected with the MPU module by IO interface, AIN0 interface;

[0094] The Ethernet module is used to transmit Ethernet data obtained from switch to MPU module;

[0095] The WiFi module is configured to transmit the first wireless data obtained from the antenna seat to the MPU module.

[0096] The universal acquisition module is configured to transmit the analog quantity data obtained from the AIN0 interface and the digital quantity data obtained from the IO interface to the MPU module.

[0097] The MPU module is configured to upload the obtained Ethernet data, the first wireless data, the analog quantity data and the digital quantity data to the cloud platform.

[0098] Working principle: In this embodiment, the Ethernet module is configured to transmit the Ethernet data obtained from the switch to the MPU module; the WiFi module is configured to transmit the first wireless data obtained from the antenna seat to the MPU module; the universal acquisition module is configured to transmit the analog quantity data obtained from the AIN0 interface and the digital quantity data obtained from the IO interface to the MPU module; and the MPU module is configured to upload the obtained Ethernet data, the first wireless data, the analog quantity data and the digital quantity data to the cloud platform for unified configuration and management, thereby improving the overall performance and reliability of the Internet of Things system.

[0099] The reliable multifunctional edge gateway takes a high-performance MPU (ZMP1107) as a control core to realize local hardware resource control of the entire gateway, control and configuration data and acquisition data processing of the upper and lower ends, and system reliability guarantee and other functions. The reliability of the multifunctional edge gateway is controlled by the MPU. In this embodiment, the reliability is increased in two aspects: one is to convert the data of the device terminal to process the data according to the unified standard of the platform, and the other is to perform cyclic buffer processing on the data of the device terminal. The multifunctional edge gateway converts all the collected data into the unified standard data coding format of the cloud platform according to the configuration standard of the cloud platform and uploads the data. The unified standard of the data processed by the cloud platform is ensured, and the processing resource consumption of the cloud platform is reduced. The data acquisition device terminal and the point are managed by the cloud platform. The multifunctional edge gateway receives the configuration information of the cloud platform, collects, converts and analyzes the data according to the configuration information of the cloud platform, and dynamically uploads the data according to the rules. This is a method for solving the data transparent transmission of the gateway on the market, reducing the resource consumption of the cloud platform.

[0100] In the cyclic buffer processing of the device terminal data, the MPU divides the internal Flash into a program storage area and a data storage area, wherein the program storage area is used to place the space for running programs, and the data storage area is used to construct the cyclic buffer of data. When the data channel of the multi-functional edge gateway connected to the cloud platform is abnormal, the multi-functional edge gateway temporarily stores the data collected from the device terminal. Once the data channel of the Internet is restored to normal, the data is immediately uploaded to the server at high speed. In this way, the loss of device terminal data caused by abnormal uplink channel is avoided. In addition, because the cyclic buffer of data is constructed on the Flash, even if the multi-functional edge gateway suddenly loses power, the data in the previous buffer will not be lost due to power failure. When the multi-functional edge gateway is powered on again, the data in the Flash can be uploaded to the service. This is another effective measure to improve data reliability.

[0101] The multi-functional edge gateway takes ZMP1107 MPU as the core, supports data collection and interaction of multiple communication protocols, and supports data conversion into a unified standard data coding format of the cloud platform. The unified standard of the cloud platform processing data is guaranteed, and the processing resource consumption of the cloud platform is reduced. The data collection points are managed by the cloud platform, the multi-functional edge gateway receives the configuration information from the cloud, collects, converts, and analyzes data according to the configuration information from the cloud, and dynamically uploads according to the rules. The RJ45 network port, wifi, and 4G of the multi-functional edge gateway can be used as the port for uploading the cloud platform. At the same time, the 4-way RJ45 network port supports the switch function to provide convenience for the networking of other devices on site, and reduces the use amount of on-site devices in cooperation with the use scene.
