Fig. 7B is a schematic diagram showing a machine instruction element format of a control method for a gas range according to an exemplary embodiment, and fig. 7C is a schematic flowchart showing a control method for a gas range according to another exemplary embodiment. As shown in fig. 7B and 7C, the touch instruction and the knob trigger instruction generated by the touch key and the fire control knob are not directly used to adjust the operating state of the gas cooker, but are first put into a first-in first-out instruction queue according to the time sequence, and each machine instruction enters the queue and is stored as a unit according to the instruction queue element, that is, before storage, a user instruction needs to be converted into a machine instruction including each instruction queue element, and the instruction queue element includes five elements of an instruction executable identifier/execution identifier bit, a source identifier bit, a generation time/time identifier bit, an instruction description and a priority identifier.

When the executable identifier enters the queue, the executable identifier is in an unset state, which indicates that the current instruction has not been processed/optimized and is in a non-executable stage. After the processing/optimizing process, the executable identifier in the queue element of the still existing machine instruction is set to represent that the machine instruction can be sequentially executed in the instruction queue; "source" means whether the command is generated by a touch key or a fire control knob or a mobile terminal; "instruction generation time _ sequence number" indicates the order of generation of the instruction; "instruction description" means the specific meaning and parameters carried by this instruction; "priority" indicates the importance of this instruction and whether the execution order of other instructions can be preempted, resulting in an instruction reorder when optimizing instructions.

When the gas stove works, the control device/the instruction adjusting module always carries out the processing/optimizing process of the instruction sequence according to the following rules:

a) when the touch key or the fire control knob generates an instruction, packaging/converting the instruction according to the element format of the instruction queue, converting the instruction into a machine instruction and putting the machine instruction into the instruction queue;

b) the control device searches/searches for the machine instruction/instruction element with the unset executable identifier in the instruction queue, and simultaneously obtains the attributes of all other elements with the set executable identifier in the instruction queue for one-to-one comparison; if each element of the current machine instruction is consistent with any one of the set element attributes, the current machine instruction is regarded as a repeat instruction, the instruction element is deleted, and otherwise, the operation is turned to c;

c) comparing the instruction element with a preset command response rule corresponding to the mode or state of the current gas stove, if the instruction element is an invalid command or a command in an abnormal command table, deleting the instruction element, and otherwise, turning to the step d;

d) comparing the instruction with the priority levels of all other elements with set executable identifiers in the instruction queue one by one, if the priority level of the instruction is the highest, placing the instruction at the head of the instruction queue, setting the executable identifiers of the instruction, and determining whether other instructions with lower priority levels are deleted according to a preset rule, otherwise, turning to e;

e) setting the executable identifier of the instruction, and adjusting the sequence of the instruction in the instruction queue according to the instruction generation time _ sequence number;

f) taking out the instruction with the setting of the executable identifier in the instruction queue and positioned at the head of the instruction queue, immediately changing the working state of the gas stove according to the instruction description, then deleting the instruction element, and rearranging the rest instructions.

The command queue and the command adjusting steps a-f ensure that when a touch command and a knob trigger command are received, the gas stove is sequentially controlled to adjust the running state of the gas stove according to the command based on the response sequence of the touch execution and knob trigger command according to a preset queue rule. Repeated instructions, invalid instructions and abnormal instructions are eliminated according to a preset rule, and the response sequence can be adjusted according to the instruction priority, so that the important instructions are ensured to be quickly responded, and the optimization operation of the response sequence of the multi-instruction control of the gas stove is realized.

After the gas stove normally operates, information display instructions generated by a touch key, a fire control knob or a control device/a main control MCU are firstly put into a first-in first-out display instruction queue according to the generated time sequence, each display instruction enters the queue and is stored by taking a display instruction queue element as a unit, and the display instruction queue element comprises seven elements of a display instruction executable mark, a display request source, display request generation time, display instruction description, display priority, display action and display duration. The display instruction executable flags are all in an unset state when the display instruction just enters the queue, and indicate that the current display instruction is not in a logic judgment process and is in an unexecutable stage. After the processing analysis/logic discrimination process, the executable mark in the still existing element of the display instruction is set, which represents that the display instruction can be sequentially executed in the display instruction queue; the 'display request source' indicates that the display instruction is generated by the cooking state and the error state of a touch key, a fire control knob or a main control MCU; "display request generation time" indicates the order of generation of the display instruction; "display instruction description" indicates the specific meaning of this instruction and the Led code number of the specified control; the display priority represents the importance degree of the display instruction and whether the execution sequence of other display instructions can be preempted, so that the instructions are rearranged when the display instructions are logically processed; the display action represents the specific action of the display instruction control Led, including three states of lighting up, turning off and flashing, wherein the flashing also has a flashing frequency parameter; the display duration represents the remaining time of the Led controlled by the instruction to perform the display action, and when the display duration is 0, the display instruction is executed.

As shown in fig. 7D, when the gas stove is in operation, the display queue always controls the information display process of the Led lamp according to the following logic:

a) when the touch key, the fire control knob or the main control MCU generates a display instruction, packaging the instruction according to the instruction queue element format, and putting the instruction into a display instruction queue;

b) comparing the display instruction element with a display rule corresponding to the mode or state of the current gas stove, if the display instruction element is an invalid display instruction or an instruction in an abnormal display instruction list, deleting the display instruction element, and otherwise, turning to the step c;

c) comparing the display instruction with the priority levels of all other elements with set executable marks in a display instruction queue one by one, if the priority level of the display instruction is the highest, placing the display instruction at the head of the display instruction queue, setting the executable marks of the display instruction, and determining whether to delete other display instructions with lower priority levels according to a preset rule, otherwise, turning to d;

d) setting an executable mark of the display instruction, and adjusting the sequence of the display instruction in an instruction queue according to display request generation time;

e) taking out all executable mark setting instructions in the instruction queue, judging whether the display duration of the executable mark setting instructions is greater than 0, if so, immediately carrying out specific control operations such as on, off and flashing on the specified Led described by the display instruction according to the action described in the display action, and simultaneously subtracting 1 from the display duration. If the value is 0, deleting the display instruction element, releasing the display space and rearranging the rest instructions.
