Description

Technical Field

[0001] The present invention relates to a monitoring and control technology for a ship's sinking and buoyancy and attitude balance system, which is applicable to the design of a ship's sinking and buoyancy and attitude balance system or a pressure displacement loading system, and in particular to a heavy load inquiry control method and system for a ship's pressure displacement loading device. Background Art

[0002] According to the requirements of relevant specifications and standards, before a large-power load device is put into use on a ship, a heavy load inquiry should be carried out first, and it can only be put into use after obtaining permission from the power station monitoring system to ensure that the operating power of the ship's power grid meets the use requirements and avoid power outages, short circuits and other faults in the ship's power grid when directly turning on large-power load equipment.

[0003] For large ships or special ships with high demands for ship attitude adjustment, they have high requirements for operation time and efficiency. Ballast load devices are key equipment in the sinking and floating and attitude balance system, and generally include large-displacement ballast pumps, large-displacement ballast load air compressors and other high-power equipment. However, the high-power ballast load device needs to go through a heavy-load inquiry process before starting, which will extend the sinking and floating operation time and reduce the response speed of the sinking and floating and attitude balance system. In order to ensure that the ballast load device can be put into use quickly when the ship's sinking and floating tasks are required, the automation and intelligence of its heavy-load inquiry control method and system are of great significance to ensuring the realization of the sinking and floating operation time indicators and improving the efficiency of ship sinking and floating operations. Summary of the invention

[0004] For large ships or special ships with high demands for ship attitude adjustment, in order to ensure that the pressure-displacement load device can be quickly put into use when the ship's sinking and floating tasks require it, to ensure the realization of the sinking and floating operation time index, and to improve the efficiency of the ship's sinking and floating operations, the present invention proposes a ship pressure-displacement load device heavy load inquiry control method and system. The system mainly includes a system integrated control device, a signal sub-control box, a pressure-displacement load device control box, and a power station monitoring system, which are connected through communication cables. There may be one or more pressure-displacement load device control boxes to achieve remote control and local control of the pressure-displacement load device and improve the vitality of the control system. The control method includes a remote control method and a local control method. Through this method and system, the degree of automatic control of the heavy load inquiry before the pressure-displacement load device is improved, the starting response speed of the pressure-displacement load device is accelerated, and the convenience of operation and the efficiency of ship sinking and floating operations are improved.

[0005] The technical solution of the present invention is:

[0006] A heavy load inquiry control system for a ship pressure relief load device, comprising a system integrated control device, a signal sub-control box, a pressure relief load device control box, and a power station monitoring system; the system integrated control device is a remote control terminal of the pressure relief load device, and is provided with <remote control>, <heavy load inquiry>, <heavy load permission>, <start>, <stop / cancel> soft / hard operation buttons and status indications, and is directly connected to the signal sub-control box through a communication cable; the signal sub-control box is directly connected to the system integrated control device and the pressure relief load device control box through communication cables respectively; the pressure relief load device control box is an on-site control terminal of the pressure relief load device, and is provided with <local / remote control>, <heavy load inquiry>, <heavy load permission>, <start>, <stop / cancel> soft / hard operation buttons and status indications, and is directly connected to the signal sub-control box and the power station monitoring system through communication cables respectively; the power station monitoring system is a ship power grid management terminal, and is provided with <heavy load inquiry>, <heavy load permission> soft / hard operation buttons and status indications for the pressure relief load device, and is directly connected to the pressure relief load device control box through a communication cable;

[0007] The pressure-displacement load device control box continuously sends a "remote control status indication" hold signal to the system integrated control device; when in the remote control state, the pressure-displacement load device control box and the system integrated control device <remote control> indication are always on; when in the local control state, the system integrated control device <remote control> has no indication;

[0008] The control box of the pressure-displacement load device continuously sends the "operation status" hold signal to the system integrated control device and the power station monitoring system; when the pressure-displacement load device is in the operation status, the <start> indication of the system integrated control device and the pressure-displacement load device control box is always on; when the pressure-displacement load device is in the stop status, there is no <start> indication of the system integrated control device and the pressure-displacement load device control box;

[0009] <Stop / Cancel> button and status indicator: when the pressure-displacement load device is in operation, the system's integrated control device or the pressure-displacement load device control box's <Stop / Cancel> button and status indicator enable the pressure-displacement load device to stop; when the pressure-displacement load device is in stop status, the system's integrated control device or the pressure-displacement load device control box's <Stop / Cancel> button and status indicator enable the system's integrated control device or the pressure-displacement load device control box to stop sending the "heavy load inquiry" hold signal, and the signal is reset.

[0010] Furthermore, the communication cables can generally adopt serial, parallel, Ethernet, switch quantity / analog quantity communication modes.

[0011] Furthermore, the <Heavy Load Inquiry>, <Start>, and <Stop / Cancel> buttons on the system integrated control device also have status indication functions, and <Remote Control> and <Heavy Load Allow> only have status indication functions; the <Local / Remote Control>, <Heavy Load Inquiry>, <Start>, and <Stop / Cancel> buttons on the pressure relief load device control box should have status indication functions at the same time, and <Heavy Load Allow> only has a status indication function; the <Heavy Load Inquiry> on the power station monitoring system only has a status indication function, and the <Heavy Load Allow> button should have a status indication function at the same time.

[0012] Furthermore, the system integrated control device, signal sub-control box and power station monitoring system are one, and there can be multiple control boxes for the pressure-displacement load device; when there are multiple control boxes for the pressure-displacement load device, there should be multiple corresponding groups of <local / remote control>, <heavy load inquiry>, <start>, <stop / cancel> buttons and status indicators in the system integrated control device, and there should be multiple corresponding groups of <heavy load allow> buttons in the power station monitoring system.

[0013] A method for controlling a heavy load inquiry of a ship's pressure-displacement loading device, which is used for the heavy load inquiry control system of the ship's pressure-displacement loading device, is a remote control method, comprising the following steps:

[0014] S1.1. The crew member presses the <Heavy Load Inquiry> button on the system integrated control device; at this time, the system integrated control device sends a "Heavy Load Inquiry" hold signal to the signal sub-control box; the signal sub-control box sends the hold signal to the pressure-displacement load device control box, so that the <Heavy Load Inquiry> indicator on the pressure-displacement load device control box is always on; the pressure-displacement load device control box feeds back the "received" hold signal, which is finally transmitted to the system integrated control device via the signal sub-control box, so that the <Heavy Load Inquiry> indicator on the system integrated control device is always on, and at the same time, the pressure-displacement load device control box sends a "Heavy Load Inquiry" hold signal to the power station monitoring system;

[0015] S1.2. After the power station monitoring system receives the "heavy load inquiry" hold signal, it analyzes whether the pressure relief load device can be allowed to start according to the power consumption of the ship's power grid at this time; if the starting conditions are not met, the crew operates the <Stop / Cancel> button on the system integrated control device to stop the system integrated control device from sending the "heavy load inquiry" hold signal and reset the "heavy load inquiry" hold signal, that is, the <heavy load inquiry> indication of the system integrated control device and the pressure relief load device control box is cancelled, and the process ends; if the starting conditions are met, the crew operates the power station monitoring system to send a "heavy load allowed" hold signal to the pressure relief load device control box, so that the <heavy load allowed> indication on the pressure relief load device control box is always on, and at the same time, the pressure relief load device control box sends a "heavy load allowed" hold signal to the signal sub-control box, and then the signal sub-control box sends a "heavy load allowed" hold signal to the system integrated control device, so that the <heavy load allowed> indication on the system integrated control device is always on;

[0016] S1.3. When the <heavy load allowed> indicator on the system integrated control device is always on, the crew member presses the <start> button on the system integrated control device, and the system integrated control device sends a "start" instantaneous signal to the signal sub-control box and stops sending the "heavy load inquiry" holding signal at the same time. At this time, the "heavy load inquiry" holding signal is reset; the signal sub-control box sends a "start" instantaneous signal to the pressure-displacement load device control box, so that the pressure-displacement load device control box executes the command to start the pressure-displacement load device. After the start is successful, the <start> indicator of the pressure-displacement load device control box is always on; because the system integrated control device and the power station monitoring system continue to receive the "operating status" holding signal from the pressure-displacement load device control box through the signal sub-control box, the <start> indicator of the system integrated control device is always on at this time, and the power station monitoring system stops sending the "heavy load allowed" holding signal, and the "heavy load allowed" holding signal is reset;

[0017] S1.4. After the ship's sinking and floating operation is completed, the crew operates the <Stop / Cancel> button on the system's integrated control device, and the system's integrated control device sends a "Stop" instantaneous signal to the signal sub-control box, which sends a "Stop" instantaneous signal to the pressure-displacement load device control box. The pressure-displacement load device control box executes the command to stop the pressure-displacement load device. After the stop is successful, the <Start> indication of the pressure-displacement load device control box is cancelled; since the system's integrated control device and the power station monitoring system continue to receive the "Operation Status" hold signal from the pressure-displacement load device control box through the signal sub-control box, the <Start> indication of the system's integrated control device is cancelled at this time.

[0018] A method for controlling a heavy load inquiry of a ship pressure displacement loading device, which is used for the heavy load inquiry control system of the ship pressure displacement loading device, is an on-site control method, and the specific steps of the on-site control method are as follows:

[0019] S2.1. The crew member operates the <heavy load inquiry> button on the pressure relief device control box to make the <heavy load inquiry> indicator always on, and at the same time sends the "heavy load inquiry" hold signal to the signal sub-control box and the power station monitoring system; the signal sub-control box sends the "heavy load inquiry" hold signal to the system integrated control device, making the <heavy load inquiry> indicator of the system integrated control device always on;

[0020] S2.2. After the power station monitoring system receives the "heavy load inquiry" hold signal, it analyzes whether the pressure relief load device can be allowed to start according to the power consumption of the ship's power grid at this time; if the starting conditions are not met, the crew presses the <Stop / Cancel> button on the pressure relief load device control box to stop the pressure relief load device control box from sending the "heavy load inquiry" hold signal, and the signal is reset, that is, the <heavy load inquiry> indication of the system integrated control device and the pressure relief load device control box is cancelled, and the process ends; if the starting conditions are met, the crew operates the power station monitoring system to send a "heavy load allowed" hold signal to the pressure relief load device control box, so that the <heavy load allowed> indication on the pressure relief load device control box is always on, and at the same time, the pressure relief load device control box sends a "heavy load allowed" hold signal to the signal sub-control box, and the signal sub-control box sends a "heavy load allowed" hold signal to the system integrated control device, so that the <heavy load allowed> indication on the system integrated control device is always on;

[0021] S2.3. When the <heavy load allowed> indicator on the pressure relief load device control box is always on, the crew member operates the <start> button on the pressure relief load device control box, and the pressure relief load device control box stops sending the "heavy load inquiry" hold signal. At this time, the "heavy load inquiry" hold signal is reset, and the command to start the pressure relief load device is executed. After the start is successful, the <start> indicator on the pressure relief load device control box is always on; because the system integrated control device and the power station monitoring system continue to receive the "operating status" hold signal from the pressure relief load device control box through the signal sub-control box, the <start> indicator on the system integrated control device is always on, and the power station monitoring system stops sending the "heavy load allowed" hold signal, and the "heavy load allowed" hold signal is reset;

[0022] S2.4. After the ship's sinking and floating operation is completed, the crew operates the <Stop / Cancel> button on the pressure-displacement load device control box, and the pressure-displacement load device control box executes the command to stop the pressure-displacement load device. After the stop is successful, the <Start> indication of the pressure-displacement load device control box is cancelled; because the system integrated control device and the power station monitoring system continue to receive the "operating status" holding signal from the pressure-displacement load device control box through the signal sub-control box, the <Start> indication of the system integrated control device is cancelled at this time.

[0023] Furthermore, in the remote control method, except for the control of <heavy load inquiry>, <stop / cancel>, <start> of the system integrated control device and <heavy load permission> of the power station monitoring system, which require crew operation, other operations are automatic control processes.

[0024] Furthermore, in the local control method, except for the <heavy load inquiry>, <stop / cancel>, <start> of the pressure discharge loading device control box and the <heavy load permission> of the power station monitoring system, which require crew operation, other operations are automatic control processes.

[0025] Furthermore, the "heavy load inquiry", "heavy load permission" and "operating status" signals are holding signals; the "start" and "stop / cancel" signals are instantaneous signals; the "heavy load inquiry" or "heavy load permission" holding signal reset means that when the "heavy load inquiry" or "heavy load permission" holding signal stops sending, the indication of the corresponding permanently lit indication part is automatically canceled.

[0026] Furthermore, the buttons and status indicators of the system integrated control device, the pressure-displacement load device control box, and the power station monitoring system are aimed at a certain pressure-displacement load device; the control methods of different pressure-displacement load devices are the same.

[0027] The beneficial effects of the present invention are:

[0028] A multi-level ship pressure relief load device heavy load inquiry control system is proposed. The system integrated control device and the pressure relief load device control box are the remote control terminal and the local control terminal of the pressure relief load device respectively, which improves the vitality of the pressure relief load device control system. The pressure relief load device control box exchanges information with the power station monitoring system to ensure the safe and reliable operation of the ship's power grid, and provide ideas for the control design of the ship's sinking and attitude balance system.

[0029] A heavy load inquiry control method for a ship's pressure displacer loading device is proposed. According to this method, the control process and control strategy can be designed to reduce the crew's operating steps, improve the degree of automatic control of the pressure displacer loading device's heavy load inquiry control process, and improve the operating convenience and efficiency of the ship's sinking and floating operations.

[0094] More specifically, the control box of the No. 1 pressure-displacement load device continuously sends a "running state" hold signal (S116) to the system integrated control device through the signal sub-control box (S114); the control box of the No. 1 pressure-displacement load device continuously sends a "running state" hold signal (S115) to the power station monitoring system. Therefore, when the No. 1 pressure-displacement load device is in the running state, the No. 1 pressure-displacement load device <start> indication of the system integrated control device is always on; when the No. 1 pressure-displacement load device is in the stopped state, the No. 1 pressure-displacement load device <start> indication of the system integrated control device is cancelled and there is no indication.

[0095] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
