[0067] The manual interface two key in the interface is clicked to enter the manual interface two, and the interface is more convenient for comparing water level relationships of two gate chambers and upstream and downstream. The manual interface one is clicked to return to the manual interface one.

[0068] After the manual operation is completed, the return key is pressed to exit the interface and return to the main interface.

[0069] The valve opening time, the signaling time, the leveling time and the reverse water head are of a power-off maintaining type, and the data is refreshed again only when the valve is next operated and the triggering condition is met. When a valve is selected, the data of the valve is displayed, and the data of other valves is not displayed.

[0070] As Figure 7 shown, the operation interface of the filling and draining preparation is used for setting parameters required by the filling and draining preparation actions, one of the gate chambers can be subjected to the filling and draining preparation actions, or the filling and draining preparation actions of mutual filling of the A gate chamber and the B gate chamber can be performed.

[0071] The filling and draining preparation key provided by the application is used in the following manner: the "filling and draining preparation" key in the main interface is pressed to enter the filling and draining preparation operation interface. In this interface, various parameters required by the filling and draining preparation actions can be set. The filling and draining preparation actions can be performed on a single gate chamber, or the filling and draining preparation actions of mutual filling of two gate chambers can be performed.

[0072] After the preparation operation is completed, the "return" key is pressed to return to the main interface.

[0073] As Figure 8 and Figure 9 shown, the forced / automatic operation interface selects one mode from six modes for operation.

The dashed line indicates the position of the high-low probe, and the scale line is displayed in real time according to the measured data. The water level leveling time of the related gate chambers and the maximum reverse water head are calculated.

[0077] Before the valve operates, the "pulse opening degree" key is pressed to realize mutual conversion of the pulse opening degree and the valve opening degree. During the valve operation, the key should not be pressed.

[0078] If a certain gate chamber water level exceeds the alarm setting value during operation, the system alarms and simultaneously performs the upper gate head opening and lower gate head action of closing the gate chamber.

[0079] If an abnormal condition occurs, the "emergency stop" key can be pressed at any time, the system immediately stops all actions and immediately performs the upper gate head opening and lower gate head action of closing the gate chamber.

[0080] After automatic operation is completed, the "return" button is pressed to exit the interface and return to the main interface.

[0081] When the valve is fully opened or closed, the color is displayed differently.

[0082] The valve opening time, signaling time, level time, and reverse water head are data retention type, and the data is refreshed when the valve next time acts and meets the triggering condition. When a certain valve is selected, the data of the certain valve is displayed, and the parameters of other valves are not displayed.

[0085] As shown in Figure 10 The emergency stop / alarm operation interface is used to monitor the water levels of the plurality of gate chambers in real time, the over-limit water level of the plurality of gate chambers is set, when the water level of one of the gate chambers exceeds the over-limit water level setting value, the system alarms and simultaneously performs the upper gate head opening and lower gate head action of closing the gate chamber, and the emergency stop / alarm operation interface is also used to monitor the opening values of the plurality of valves and the water levels of the plurality of gate chambers.

The opening values of the valves and the water levels of the gate chambers are monitored in real time.

[0087] If a certain gate chamber water level exceeds the alarm setting value during operation, the system alarms and simultaneously performs the upper gate head opening and lower gate head action of closing the gate chamber.

[0088] As shown in Figure 11 The gate debugging mode interface, in the interface, the operation buttons of the control panel are invalid, only the opening and closing of one valve can be controlled by operating the buttons on the touch screen, and the actual travel of each valve is confirmed according to the displayed values.

[0089] When using the gate debugging mode button provided by this invention, pressing the "Gate Debugging Mode" button on the main interface will enter the gate debugging mode interface. In this interface, the operation buttons on the electrical cabinet door panel are invalid; only the buttons on the touch screen can be used to control the opening and closing of a specific valve, and the actual stroke of each valve can be confirmed according to the displayed values.

[0090] After debugging, press the "Back" button to exit this interface and return to the main interface.

[0091] like Figure 12 As shown, the valve opening conversion interface provides calculation formulas for the mutual conversion between valve opening and pulse opening. The expression of the calculation formula is as follows:

[0092] y = ax 3 +bx 2 +c

[0093] Among them, the abc coefficient is set by the operating conditions, and the x value is the real-time opening degree of the valve during operation. When operating manually or automatically, the system will automatically calculate and perform motion control based on the coefficient and the real-time opening degree.

[0094] When using the valve opening conversion button provided by this invention, pressing the "Opening Conversion" button on the main interface will enter the valve opening conversion interface. This interface provides mutual conversion calculations between valve opening and pulse opening; the abc coefficient in the function is open and can be set by the user according to the working conditions, and the x value is the real-time opening of the valve during operation. When running manually or automatically, the system will automatically calculate and perform motion control based on the coefficient and the real-time opening.

[0095] like Figure 1 As shown, the control panel is configured with a trigger signal and a valve opening analog quantity. The trigger signal and valve opening analog quantity are applied to the gate valve selected in manual or forced / automatic mode. In the case of two valves, the right valve is selected; in the case of a single valve, the valve being operated is selected. The trigger signal is a dry contact that outputs for 4 seconds when the selected valve opens from the closed position. The valve opening analog quantity signal is real-time data with a refresh rate of not less than 10 times per second and an amplitude of 0-5V, corresponding to an opening degree of 0%-100%.

[0096] When the trigger signal and valve opening analog quantity output provided by this invention are used, the trigger signal and valve opening analog quantity objects are the gate valve selected in manual or automatic / forced mode. In the case of two valves, the right valve is selected, and in the case of a single valve, the valve actually operated is selected. The trigger signal is a passive contact. When the selected valve is opened from the closed position, the contact is connected for 4 seconds.

[0097] The valve opening degree analog signal is real-time data, the refresh rate is not less than 10 times per second, the amplitude is 0-5V, and 0-100% of the valve opening degree is respectively corresponded. The trigger signal and the valve opening degree analog signal do not interfere with the normal data collection of other data collection instruments.

[0098] Working principle: When A chamber and B chamber are parallelly arranged in use, A chamber needs to discharge water while B chamber needs to fill water, B chamber opens the upper lock head and the mutual filling valve at the same time, so that B chamber can take water from the upstream and A chamber at the same time, when the water levels of A chamber and B chamber are level, the mutual filling valve is closed, B chamber continues to take water from the upstream, A chamber opens the lower lock head, and A chamber continues to discharge water to the downstream; similarly, when A chamber needs to fill water and B chamber needs to discharge water, the same is true. On the basis of realizing complete independent operation of the ordinary double-line ship lock, the cooperative operation, water level control and control of the mutual filling valve between A chamber and B chamber are increased, so that A chamber and B chamber can completely independently operate and do not interfere with each other, and can also cooperatively operate to save water resources.

During the origin regression process, the "stop" button can be pressed at any time to stop the origin regression action.

[0101] The "manual" button in the main interface is pressed to enter the manual interface one, when a valve is selected for operation, the parameters and data of the valve are highlighted on the touch screen, which is convenient for observation and operation. At the same time, the water levels of each chamber and the water level difference are displayed in real time; the real-time opening degree of the left valve and the action parameters of each valve are displayed beside the valve, the running frequency and pulse number of the valve are automatically calculated according to the maximum opening degree and valve switching speed, the water level equalization time of the related chamber and the maximum reverse water head are calculated;

[0102] If the water level of a chamber exceeds the alarm setting value during the operation process, the system alarms and closes the upper valve and opens the lower valve of the chamber. If an abnormal condition occurs, the "emergency stop" button can be pressed at any time, the system immediately stops all actions, and immediately executes the closing of the upper lock head and the opening of the lower lock head.
