The following more visual description of the steps is made according to the decision logic created for the method;
in the valve opening stage, referring to fig. 1, when a valve opening command open_c3 is received, the value of the valve opening command open_c3 is changed from 0 to 1, specifically, the valve opening command open_c3 refers to a command that an external staff or a program wants to Open a valve, a carrier of the valve opening command open_c3 can be a button, a trigger, a program and the like, and the valve opening command open_c3 is output in a delayed manner, so that the valve reversing speed is changed, hydraulic impact generated during reversing is reduced, and a pulse signal is delayed for 2 seconds generally; the value of the valve opening output instruction Open_out1 is changed from 0 to 1, the values of the valve opening command Open_c3 and the valve opening output instruction Open_out1 are 1, the value output after logic AND is 1, the value output by the valve opening command Open_c3 after logic negation is 0, the value output by the logic AND is different from the value output by the logic negation, the logic exclusive OR is output 1, and the RS trigger receives signals.
In the valve unopened stage, referring to fig. 1, when the valve opening command open_c3 is not received, the value of the valve opening command open_c3 is 0; the value of the valve opening output instruction Open_out1 is 0, the values of the valve opening command Open_c3 and the valve opening output instruction Open_out1 are 0, the value output after logic AND is 0, the value output by the valve opening command Open_c3 after logic AND is 1, the value output by the logic AND is different from the value output by the logic AND is 1, and the signal is received by the RS trigger.
When the valve signal is unblocked, referring to fig. 1, when the valve opening command open_c3 is received, the value of the valve opening output command open_out1 is changed from 0 to 1, because the values of the valve opening command open_c3 and the valve opening output command open_out1 are both 1, the value output after the logical AND is 1, the value output by the valve opening command open_c3 after the logical AND is 0, the value output by the logical AND is different from the value output by the logical OR, the value output by the logical OR is 1, the value of the valve signal unblocked signal instr_on11 is not assigned to 1, and before the RS trigger, the value output by the logical OR needs to be subjected to logical AND operation with the valve signal unblocked signal instr_on11, and when the value of the valve signal unblocked signal instr_on11 is not 1, the RS trigger does not receive the signal.
When the command-not-communication fault signal in the valve opening stage is generated, when the valve-opening command Open_c3 is received, the value of the valve-opening command Open_c3 is changed from 0 to 1, but the valve signal is not communicated due to internal logic of the valve, the value of the valve-opening output command Open_out1 is still 0, the value of the valve-opening command Open_c3 is 1, the value of the valve-opening output command Open_out1 is 0, the value output after the logical AND is the same as the value output after the logical AND is the logical OR output 0, the RS trigger does not receive a signal, and the command-not-communication fault signal Instr_off12 is triggered.
In summary, during both the valve open phase and the valve unopened phase, the RS flip-flop can receive the signal, and when the command-failure signal is generated, the RS flip-flop does not receive the signal, triggering the command-failure signal.
In the stage of opening the Valve to the preset position, referring to fig. 2, when the Valve opening command open_c3 is received, the value of the Valve opening command open_c3 is changed from 0 to 1, the value of the Valve opening output command open_out1 is 1, the value output after the logical and is 1, when the Valve is opened to the preset position, the Valve opening state signal valve_w_o_s5 is triggered and fed back, the value of the Valve opening state signal valve_w_os5 is changed from 1 to 0, after the logical negation, the value of the Valve opening state signal valve_w_o_s5 is changed from 0 to 1, the value of the logical and is 1, the value output after the logical and is 1, and the rs trigger receives the signal.
When the Valve fault signal in the Valve opening stage is generated, referring to fig. 2, when the Valve opening command open_c3 is received, the value of the Valve opening command open_c3 is changed from 0 to 1, the value of the Valve opening output command open_out1 is 1, the value output after the logical AND is 1, when the Valve is opened to a preset position, but the Valve is not triggered and feeds back the Valve Open-in-place state signal valve_w_o_s5 due to external reasons such as Valve fault and Valve blocking, the value of the Valve Open-in-place state signal valve_w_o_s5 is 1, the value of the Valve Open-in-place state signal valve_w_o_s5 is changed from 1 to 0 after the logical inverse, the value of the logical AND is 1, the value of the logical inverse is 0, the value output after the logical AND is 0, the rs trigger does not receive the signal, and the Valve fault signal v_p_er8 is triggered.
Executing and feeding back a valve closing output instruction when a valve closing command is received and a valve closing condition is met, so that the valve performs valve closing action, triggering and feeding back a valve closing in-place state signal when the valve is closed to a preset position, stopping executing and feeding back the valve closing output instruction, and stopping the valve closing action;
when a valve closing command is received and a set valve closing signal threshold time is passed, outputting a command failure signal when a valve closing output command is not executed, and outputting a valve signal unblocking signal when the valve closing command is received and the valve closing output command is executed within the set valve closing signal threshold time; when the valve is closed and reaches the threshold time of the valve closing signal, the valve fault signal is output and the execution and feedback of the valve closing output instruction are stopped if the valve closing in-place state signal is not received.
Similarly, the step is more intuitively described according to the judgment logic;
referring to fig. 3, in the valve closing stage, when the valve closing command close_c9 is received, the value of the valve closing command close_c9 changes from 0 to 1, specifically, for ensuring safety, the value of the valve opening command open_c3 and the valve closing command close_c9 cannot be triggered simultaneously, that is, when the valve opening command open_c3 is 1 from 0, the valve closing command close_c9 must be 0, or when the valve closing command close_c9 is 1 from 0, the valve opening command open_c3 must be 0, the value of the valve opening command open_out1 and the valve closing command close_out2 change from 0 to 1, and since the value of the valve closing command close_c9 and the valve closing command close_out2 are both 1, the value of the valve closing command close_c9 after being logically and reversely output is 0, the value of the valve opening command open_c3 is different from the value of the valve taking logically and the value of the reverse output is 1, and the value of the valve opening command close_c9 is logically and the value of the valve is not reversely output is received, and the rs signal is output.
Referring to fig. 3, in the non-open stage of the valve, when the valve closing command close_c9 is not received, the value of the valve closing command close_c9 is 0, the value of the valve closing output command close_out2 is 0, because the values of the valve closing command close_c9 and the valve closing output command close_out2 are both 0, the value output after the logical AND is 1, the value output after the logical AND is different from the value output after the logical AND is 1, the logical exclusive OR outputs 1, and the rs trigger receives the signal.
When the valve signal is unblocked, referring to fig. 1, when the valve closing command close_c9 is received, the value of the valve closing output command close_out2 is changed from 0 to 1, because the values of the valve closing command close_c9 and the valve closing output command close_out2 are both 1, the value output after the logical AND is 1, the value output by the valve closing command close_c9 after the logical AND is 0, the value output by the logical AND is different from the value output by the logical OR, the value output by the logical OR is 1, the value of the valve signal unblock signal instr_on11 is not assigned to 1, and before the RS trigger, the value output by the logical OR needs to be logically AND operation with the valve signal unblock signal instr_on11, and when the value of the valve signal unblock signal instr_on11 is not 1, the RS trigger does not receive the signal.
When the valve closing phase command non-communication fault signal is generated, the value of the valve closing command close_c9 is changed from 0 to 1 when the valve closing command close_c9 is received, but the valve is not enabled due to the fact that the valve signal is not enabled by internal logic, the value of the valve closing output command close_out2 is still 0, the value of the valve closing command close_c9 is 1, the value of the valve closing output command close_out2 is 0, the value output after the logic AND is the same as the value output after the logic AND is the logic hold, the logic exclusive OR is output 0, the RS trigger does not receive a signal, and the trigger command non-communication fault signal Instr_off12.
