Problems solved by technology

The maintenance equipment requires the cooperation of the engine to unlock the lock. If the lock of the main gate of the maintenance gate cannot be accurately released, it is easy to cause abnormal operation of the ship lock program. There are maintenance personnel near the valve, which may cause safety liability risks such as casualties

Embodiment Construction

[0036] Such as Figure 1-3 As shown, a multi-stage lock protection and blocking shielding control method, taking the Three Gorges five-stage ship lock as an example. The operation of the lock chamber is divided into four situations, the miter gate opening operation, the miter gate closing operation, the water delivery valve opening operation and the water delivery valve closing operation. The five-stage ship lock operation control method comprises the following steps,

[0037] Step 1: Select blocking protection or blocking shielding;

[0038] Step 1.1: If you choose to block and shield, set the maintenance flag in the running system, modify the centralized control parameters, and go to step 9;

[0039] Step 1.2: If you choose blocking protection, go to step 2;

[0040] Step 2: Determine whether to operate the miter gate or the water delivery valve;

[0041] Step 2.1: If the operation object is a miter gate, go to step 3;

[0042] Step 2.2: If the operation object is a wat...

Abstract

The invention belongs to the field of ship lock operation control, and discloses a multi-stage lock protection and lock shielding control method. When the ship lock is navigable, the lock protection of each lock head is enabled, and when the ship lock is not navigable, the corresponding lock head lock conditions can be shielded, and the The control parameters are adjusted and set to increase the convenience of ship lock operation and reduce safety risks. Control parameters include gate or valve zero point, water level parameters, gate or valve opening. The method of the present invention adopts different control modes for different ship lock states, and shields the locking of the corresponding lock head in the ship lock maintenance state, which increases the flexibility of the ship lock operation. safety.

Description

technical field [0001] The invention belongs to the field of ship lock operation control, and in particular relates to a multi-stage ship lock locking protection and locking shielding control method. Background technique [0002] During the maintenance of multi-level ship lock lock chambers, it is often encountered in the maintenance mode of draining the lock chambers. The usual lock chamber drainage method needs to go to the on-site machine room one by one to modify such as the zero point of the water level gauge at each lock head, the zero point of the gate, the zero point of the valve, and the closing delay. At the same time, it is necessary to contact the central control to confirm that the current state meets the conditions for modifying the parameters. The data of different lock heads are different, so the operation steps are cumbersome and there are many points to pay attention to; The relationship is complicated, and the equipment involved in each specific gate head ...
