The gateway stores the instruction content after receiving the timed task instruction, sends the instruction in the task to the instruction equipment at regular time according to the timed task instruction content, controls the instruction equipment or obtains the information of the instruction equipment, and returns the execution instruction result to the cloud platform when the network condition is stable; the timing task instruction of this embodiment specifically includes expected value setting information, and the expected value setting information specifically includes information such as a total number of bytes of the expected value setting information, a total number of expected values, a number of bytes of a single expected value information, a single expected value selection start bit, a single expected value dereferencing mode, a single expected value selection byte length, and an expected downlink execution instruction.
And after receiving the execution instruction result, the gateway analyzes the execution instruction result according to the rule in the expected value setting information to obtain each expected value, and simultaneously combines the expected values to obtain an expected result set.
The timed task instruction function enables the gateway to realize that one gateway is configured to be connected with a plurality of devices, and can also interact with the cloud platform at regular time, so that the network interactivity is enhanced, and command linkage execution among the devices is realized. In an offline state, the gateway can judge and execute the downlink execution of the expected value through the expected value, and linkage processing among the devices is realized.
The gateway executes the real-time query control command in time after receiving the command, issues the command to the command equipment and immediately executes the command, and immediately returns an execution result returned by the equipment to the cloud platform; real-time processing and returning of instruction contents can be realized by inquiring the control instructions in real time.
After receiving the device communication instruction, the gateway frequently performs basic communication with the instruction device in a second-level communication mode during operation, and if the return information of the instruction device is not acquired within the preset time, namely the instruction device is judged to be offline, the return information is reported to the cloud platform in real time in a return device communication instruction feedback mode, so that the real-time processing of the online state of the instruction device is realized.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
