In addition, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", and "connect in series" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood in specific circumstances.

[0022] In order to meet the design requirements for safe return to port, if the ship has at least 3 main vertical zones or its length is at least 120 meters, then the remote control valve control system of the ship needs to meet the redundant design requirements. In the prior art, a main control box is set in each main vertical zone of the ship, and each main vertical zone includes multiple Class A compartments. A loop branch box is set in each Class A compartment. Each loop branch box is only connected to all remote control valves in the Class A compartment where it is located. The main control boxes of different main vertical zones and the loop branch boxes of all Class A compartments are connected through communication links to form a loop structure. In this way, the main control box and the loop branch box have redundant power supply and communication. However, such a remote control valve control system requires a large number of loop branch boxes to meet the redundant design requirements, which increases the equipment procurement cost and the occupied layout space. In addition, due to the large number of equipment, the difficulty and workload of the analysis of safe return to port are increased.

[0023] Based on this, an embodiment of the present application provides a remote control valve control system to solve the problem that the remote control valve control system requires a large number of loop branch boxes to meet the redundant design requirements, which increases the equipment procurement cost and the occupied layout space. In addition, due to the large number of equipment, the difficulty and workload of the analysis for safe return to port are increased.

[0024] In the relevant technology, in order to prevent the occurrence of fire, ships have established a complete set of fire prevention measures, which mainly include: controlling combustibles, controlling heat sources (fire sources) and controlling ventilation, etc. At the same time, in order to ensure that the spread of fire can be effectively controlled once a fire accident occurs on the ship, the Solas Convention and my country's regulations both stipulate that during the design and construction of ships, certain fire-proof structures should be adopted, that is, the ship should be divided into several main vertical zones with fire-resistant materials that meet the regulations. The main vertical zone refers to the section where the hull, superstructure and deckhouse are divided by "A-class divisions". Its average length and width on any deck generally do not exceed 40m. In addition, the A-class compartments set up in the main vertical zone in accordance with fire prevention regulations also use watertight technology to effectively prevent water from entering the cabin and causing damage to related equipment.

[0025] The embodiment of the present application provides a remote control valve control system 100, which is used for a ship. The ship includes at least two main vertical zones and a central control system 200. The at least two main vertical zones include a first main vertical zone and a second main vertical zone. Each main vertical zone includes at least two Class A compartments 500. Each Class A compartment 500 is provided with at least one remote control valve 300. Figure 1 As shown, the control system 100 includes a first main control box 110a, a second main control box 110b and a plurality of loop branch boxes 120. The first main control box 110a is arranged in the first main vertical zone, and the second main control box 110b is arranged in the second main vertical zone; any two Class A compartments 500 in each main vertical zone are respectively provided with a loop branch box 120;

[0026] The central control system 200 establishes a communication connection with the first main control box 110a and the second main control box 110b, and the communication connection is a first communication link 400a;

[0027] A communication connection loop is established between the first main control box 110a, the second main control box 110b and each loop branch box 120 through a data transmission carrier, and the communication connection loop is a second communication link 400b;

[0028] In one embodiment, the user can select the corresponding data transmission carrier according to the different requirements of the application scenario. For example, when a short transmission distance, a low transmission rate, and a low cost are required, a network cable can be used as the data transmission carrier; for another example, when a long transmission distance and a high transmission rate are required, an optical fiber can be selected as the data transmission carrier.

[0029] The two loop branch boxes 120 and all remote control valves 300 in each main vertical zone are connected in series with the two loop branch boxes 120 as end nodes through a communication medium to establish a bidirectional bus communication connection, which is a third communication link 400c.

[0030] In one embodiment, the user can select the corresponding communication medium according to the different requirements of the application scenario. For example, when the transmission distance is short, the transmission rate is not high, and the cost requirement is low, a twisted pair or coaxial cable can be used as the communication medium; for another example, when the transmission distance is long and the transmission rate is high, an optical fiber can be selected as the communication medium.

[0031] In one embodiment, the user can select CAN-BUS communication connection or P-NET communication connection as the bus communication connection according to different requirements of application scenarios.

[0032] The first main control box 110a or the second main control box 110b is used to receive the control command sent by the central control system 200, and forward the control command to the loop branch box 120 currently in working state through the communication connection loop;

[0033] The loop branch box 120 is used to receive control instructions and control the remote control valve 300 corresponding to the control instructions when in working state, and send the state information of the remote control valve 300 collected through the bus communication connection to the first main control box 110a and the second main control box 110b;

[0034] The first main control box 110a and the second main control box 110b are also used to forward the status information sent by the loop branch box 120 which is currently in working state to the central control system 200.

[0035] In one embodiment, Figure 2As shown, Figure 2 The ship includes three main vertical zones and a central control system 200, wherein the three main vertical zones are respectively a bow main vertical zone 600a, a middle main vertical zone 600b and a stern main vertical zone 600c; the first main vertical zone may be the bow main vertical zone 600a, and the second main vertical zone may be the stern main vertical zone 600c; the bow main vertical zone 600a includes three A-class compartments 500, wherein two A-class compartments 500 at both ends are respectively provided with a main loop branch box and a standby loop branch box, and each A-class compartment includes two remote control valves 300; the middle main vertical zone 600b includes three A-class compartments 500, wherein two A-class compartments 500 at both ends are respectively provided with a main loop branch box and a standby loop branch box, and each A-class compartment includes two remote control valves 300; the stern main vertical zone 600c also includes three A-class compartments 500 00, wherein the two A-class compartments 500 at both ends are respectively provided with a main loop branch box and a standby loop branch box, and each A-class compartment includes two remote control valves 300; the first main control box 110a of the bow main vertical zone 600a, the second main control box 110b of the stern main vertical zone 600c and the central control system 200 establish a communication connection to form a first communication link 400a, and the first main control box 110a, the second main control box 110b and each loop branch box 120 establish a communication connection loop through a data transmission carrier to form a second communication link 400b, and the two loop branch boxes 120 in each main vertical zone and all the remote control valves 300, with the two loop branch boxes 120 as end nodes, establish a series bidirectional bus communication connection through a communication medium to form a third communication link 400c.

[0036] In one embodiment, this implementation is based on the above embodiments. Figure 3 As shown, the user issues a control instruction to the remote control valve 300a in the A-class compartment 500a of the bow main vertical zone 600a through the central control system 200. If the first main control box 110a and the second main control box 110b are both in normal working state, the central control system 200 can arbitrarily select one of them to send the control instruction. For example, the central control system 200 chooses to send the control instruction to the first main control box 110a in the bow main vertical zone 600a in normal working state through the first communication link 400a; the first main control box 110a forwards the control instruction to the main loop branch box 120a in the bow main vertical zone 600a in normal working state through the second communication link 400b, and the main loop branch box 120a controls the corresponding remote control valve 300a in the A-class compartment 500a through the third communication link 400c according to the control instruction, and collects the status information of the remote control valve 300a and transmits it to the central control system 200 in the reverse direction as indicated by the arrow along the aforementioned communication path (this process is all through Figure 3In addition, the main loop branch box 120a also sends the status information to the second main control box 110b through the second communication link 400b, and the second main control box 110b sends the received status information through the first communication link 400a (i.e., through Figure 3 The route and direction shown by the dotted line) are forwarded to the central control system 200.

[0037] In one embodiment, the first main control box 110a and the second main control box 110b are backed up for each other. The first main control box 110a is also used to receive all control instructions sent by the central control system 200 when the second main control box 110b fails; the second main control box 110b is also used to receive all control instructions sent by the central control system 200 when the first main control box 110a fails. This implementation is based on the above-mentioned embodiments, such as Figure 4 As shown, in Figure 3 Based on the operating state shown, the first main control box 110a is in a failed state due to its own bad factors or external force majeure factors, and the central control system 200 obtains the failure state information of the first main control box 110a through the first communication link 400a, and the central control system 200 chooses to send the control instruction through the first communication link 400a to the second main control box 110b located in the stern main vertical area 600c which is in a normal working state; the second main control box 110b forwards the control instruction through the second communication link 400b to the main loop branch box 120a in the bow main vertical area 600a which is in a normal working state, and the main loop branch box 120a controls the corresponding remote control valve 300a in the A-class compartment 500a through the third communication link 400c according to the control instruction, and collects the state information of the remote control valve 300a and transmits it to the central control system 200 in the reverse direction as indicated by the arrow along the aforementioned communication path (this process is all through Figure 4 route indicated by the solid line).

[0038] In one embodiment, the two loop branch boxes 120 in each main vertical zone include a main loop branch box 120a and a standby loop branch box 120b, and the standby loop branch box 120b is used to switch from the standby state to the working state when the main loop branch box 120a fails; this embodiment is different from the above-mentioned embodiment. Figure 3 Based on the operating status shown, Figure 5As shown, the main loop branch box 120a is in a failed state due to its own bad factors or external force majeure factors, and the standby loop branch box 120b obtains the failure status information of the main loop branch box 121 through the second communication link 400b, switches from the standby state to the working state, and the first main control box 110a forwards the control command to the standby loop branch box 120b in the bow main vertical area 600a in a normal working state through the second communication link 400b. The standby loop branch box 120b controls the corresponding remote control valve 300a in the A-class compartment 500a through the third communication link 400c according to the control command, and collects the remote control valve 300a and transmits it to the central control system 200 in the reverse direction as indicated by the arrow along the aforementioned communication path (this process is all through Figure 5 In addition, the standby loop branch box 120b also sends the status information to the second main control box 110b through the second communication link 400b, and the second main control box 110b receives the status information through the first communication link 400a (ie Figure 5 The route and direction shown by the dotted line) are forwarded to the central control system 200.

[0039] In one embodiment, this implementation is based on the above embodiments. Figure 6 As shown, if a communication failure occurs at any node in the above process, the central control system 200 can use a new communication path to control the corresponding remote control valve. For example, if a communication failure occurs at any node of the communication path: central control system 200—first communication link 400a—first main control box 110a—second communication link 400b—main loop branch box 120a of the bow main vertical zone 600a—third communication link 400c—corresponding remote control valve 300a in the A-class compartment 500a, and the central control system 200 finally fails to receive the status information of the remote control valve, then the central control system 200 determines that there is a failure in the communication path, and the central control system 200 adopts a new communication path, for example, the communication path: central control system 200—first communication link 400a—second main control box 110b—second communication link 400b—main loop branch box 120a of the bow main vertical zone 600a—third communication link 400c—corresponding remote control valve 300a in the A-class compartment 500a (i.e. Figure 6 There are certainly more communication paths to choose from, and this application does not limit this.

[0040] Another remote control valve control system 100 provided by the embodiment of the present application, based on the above embodiment, the status information includes the valve position information of the remote control valve; the first main control box 110a and the second main control box 110b are also used to execute an alarm if the remote control valve is judged to be in a failed state according to the status information. For example, the remote control valve 300a performs a corresponding action after receiving the control instruction of the main loop branch box 120a. After the remote control valve 300a is completed, the main loop branch box 120a collects the valve position information of the corresponding remote control valve 300a and forwards it to the first main control box 110a and the second main control box 110b. If the first main control box 110a and the second main control box 110b judge that the valve of the remote control valve 300a has not been actuated or the actuation is not in place according to the status information, the first main control box 110a and the second main control box 110b both judge that the remote control valve 300a is in a failed state and both execute an alarm operation.

[0041] In one embodiment, based on the above embodiment, executing the alarm includes: outputting the alarm signal through the signal element that generates the visual and / or sound signal; sending the alarm information corresponding to the status information to the central control system 200. For example, the first main control box 110a can output the visual prompt signal through the built-in LED signal light in the red constant light state, the red alternate flashing, etc., and the second main control box 110b can output the sound prompt signal through the built-in buzzer, so that the users in the bow main vertical area 600a and the stern main vertical area 600c can be informed of the alarm signal in time; after the first main control box 110a and the second main control box 110b execute the alarm operation, the alarm information corresponding to the status information is also synchronously sent to the central control system 200, so that the central control system 200 can record and respond to the alarm information.

[0042] In one embodiment, the control system 100 is connected to both the main power supply and the emergency power supply, and the emergency power supply is used to supply power to the control system 100 when the main power supply fails. In this way, the control system 100 can have a redundant power supply to maintain the normal operation of the control system 100 when the main power supply cannot continue to supply power normally.

[0043] The embodiment of the present application also provides a ship, comprising at least two main vertical zones and a central control system 200, wherein the at least two main vertical zones include a first main vertical zone and a second main vertical zone, each main vertical zone includes at least two Class A compartments 500, and each Class A compartment 500 is provided with at least one remote control valve 300; and a control system 100 according to any embodiment of the present application.

[0044] In one embodiment, the central control system 200 of the ship is used to receive the status information of the remote control valve 300 sent by the first main control box 110a and the second main control box 110b; determine the working status of the first main control box 110a and the second main control box 110b; and send the corresponding control command to the first main control box 110a or the second main control box 110b in a normal working state according to the status information. In this way, the central control system 200 can flexibly allocate the sending path of the control command according to the actual working status of the first main control box 110a and the second main control box 110b.
