The embodiment of the invention provides a configuration method of gateway equipment, which comprises the steps of storing a corresponding algorithm into a flash memory based on the configuration requirement of external equipment, and carrying out algorithm configuration or updating algorithm configuration on a processor through an algorithm configuration interface connected with the flash memory. The method can be set individually according to the user requirements, and the intelligent gateway used by each user working device only needs to run one or more algorithms corresponding to the algorithms configured by the user.
Example 3:
an embodiment of the present invention further provides a method for operating a gateway device, please refer to fig. 7, where the method includes:
s710, a processor in the gateway equipment accesses a flash memory, and it is determined that a configured algorithm exists in the flash memory and configuration data corresponding to an algorithm configuration interface connected with the flash memory is normal;
s720, the processor loads the configured algorithm in the flash memory to an operation memory for operation;
and S730, performing real-time uplink communication or downlink communication between the gateway equipment and external equipment according to the communication protocol type in the configured algorithm.
Specifically, after the gateway device is powered on, the power management module is powered on first, and converts the input voltage into a safe voltage for normal operation of each module of the gateway device, so as to ensure normal operation of the gateway.
After the gateway equipment works normally, a processor runs a program framework to access a flash memory at first, and whether a configured algorithm exists in the flash memory or not and configuration data corresponding to an algorithm configuration interface connected with the flash memory are normal or not is determined. The operating mode of the gateway device may also be determined based on the algorithm.
If the flash memory is empty or the configuration data of the algorithm configuration interface is abnormal, directly driving the indication driving circuit to give an alarm, prompting a user that the product needs to be configured or needs to be reconfigured by an indicator through an operation state indicating circuit driven by the indication driving circuit, and driving the first interface driving circuit to send a related error code through the cloud communication interface circuit, wherein the error code comprises a timestamp recorded by a real-time clock and used for error occurrence to the cloud server; and simultaneously recording the time stamp of the real-time clock and generating an error log to be stored in the expansion memory.
If the user does not do any treatment, the gateway can always work in the alarm state, and the alarm state can not be released until the user intervenes correctly. It should be noted that the alarm log only records the first failure after the power is re-turned on, so as to avoid the occurrence of "garbage" log and occupy resources.
And if the flash memory is not empty and the configuration data of the algorithm configuration interface is normal, the system enters a normal operation mode. The processor loads the configured algorithm in the flash memory into the running memory to improve the running speed, and carries out real-time communication with the field device of the user according to the communication protocol type in the algorithm configured by the user, and the working mode of the system is divided into downlink and uplink in the period.
Referring to fig. 8, the working mode of the uplink communication is that after the communication port of the user working device is connected to the communication interface of the gateway device, the gateway performs "unpacking" on the protocol through protocol analysis to analyze available data and temporarily store the data in the memory, and based on the configured algorithm, the processor takes out the data according to the data reassembly rule, re- "packs" the data according to the protocol used by the cloud, and then communicates with the cloud server through the cloud communication interface.
In upstream communication, data is filtered, and the filtering is realized by edge calculation, wherein the edge calculation refers to processing and analyzing data at a network edge node. Here we give a definition of an edge node, which refers to any node between the data generation source and the cloud center that has both computing resources and network resources. For example, the gateway is an edge node between a smart home and a cloud center. In an ideal environment, edge computing refers to analyzing and processing data near a data generation source without data circulation, thereby reducing network traffic and response time.
Referring to fig. 9, the downlink communication mode is that after the communication port of the cloud server is connected to the communication interface of the gateway device, the gateway performs protocol analysis to "unpack" the protocol to analyze available data and store the data in the memory temporarily, based on the configured algorithm, the processor extracts the data according to the data reassembly rule, and "packs" the data again according to the protocol used by the user working device, and then communicates with the user working device through the communication interface. Different from the uplink, if the cloud server issues the instruction or the data, the cloud server generally sends the operation command or the query data, and does not need to perform edge calculation, so that the cloud server can repackage the data and issue the repackaged data to the equipment only by performing security check.
The embodiment of the invention provides a working method of gateway equipment, which comprises the steps of determining that a flash memory and an algorithm configuration interface work normally, and then carrying out uplink communication or downlink communication according to requirements. The gateway equipment is also integrated with a protocol analysis program, so that the gateway equipment can deeply analyze the characteristics of user data through an intelligent algorithm in work and alarm a user after finding an abnormality.
