Status signal output DO: DO for passive switch signal output when the operator manual control switch closure signal to the first stage of the DCS system or regulator, DCS system or regulator DO status signal received after stopping PID intelligent computing wholesale traffic control device, and the operation signal output tracking valve position feedback signal. When the operation is automatically transferred from the manual control of intelligent traffic control device selection, DO status signal undone, DCS systems, or pre-regulator to control the current output value of the initial value of the recovery PID control. Similarly, when the operator intelligent traffic control device to automatically switch from manual control to the current valve position given initial values ??intelligent traffic control device prices start manual changes in control, so the operator to manually turn Auto, manual mode switch Control switches are unperturbed.
