In order to solve the above technical problem, a technical solution adopted by the present invention is to provide a method for processing device status information by a controller, including:
setting a delay preset time n as the time from the controller sending a control instruction to the receiving equipment responding to the state information of the instruction;
and after the controller sends a control instruction, delaying the preset time n to analyze the received state information, matching the state information with the sent control instruction, if the state information is matched with the sent control instruction, the state information is response state information of the instruction, and if the state information is not matched with the sent control instruction, analyzing the received state information until the state information is matched with the sent control instruction.
In the method, after the controller sends the control instruction, the controller delays the preset time n to analyze the received state information and matches the state information with the sent control instruction, and the method specifically comprises the following steps:
step S21, the controller sends a control instruction and records the current time a;
step S22, the controller receives the status information returned by the device and records the current time b;
step S23, judging whether the difference between b and a is less than the delay preset time n, if so, not analyzing the received state information, and executing step S22; otherwise, go to step S24;
step S24, analyzing the received state information, judging whether the analyzed data is matched with the current control instruction, and if so, executing step S25; otherwise, continuing to receive the data, and executing step S122;
step S25, the routine ends.
The invention uses the delay mode to identify the difference between the actual state and the configuration state of the equipment so as to ensure the effective receiving of the real data state, thereby not only avoiding the controller from processing a plurality of pieces of unnecessary state information and improving the performance of processing data, but also effectively ensuring that the real data state of the received equipment is required by the controller.
