[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.

[0031] Example 1:

[0032] Figure 1Schematic diagram of the cargo hold fan control device provided in Example 1 of the present invention.

[0033] Reference Figure 1 The cargo hold fan control device includes: a ventilation module 1, a router 2, and a communication module 3, a working module 4 and an intelligent gateway module 5 respectively connected to the router; wherein, the ventilation module 1 includes multiple fan units 11 connected in series, and the intelligent gateway module 5 is connected to the ventilation module 1 through a bus.

[0034] Here, the bus can adopt a dual bus form to enhance the redundancy of the system. The intelligent gateway module is connected to the working module through a network cable.

[0035] The communication module is used to obtain the operation status signal sent by the peripheral system connected to the communication, and send the operation status signal to the working module through the router.

[0036] The communication module connects to peripheral systems via communication protocols. For example, it can obtain ship speed and main engine status signals from the speed log system and main engine remote control system. Peripheral systems include the main switchboard, fire detection system, CO2 (carbon dioxide) release alarm system, speed log, remote control device system, main engine remote control system, satellite positioning system, and fire damper system.

[0037] The working module is used to judge the current ship working condition according to the operating status signal, generate a first control signal according to the ship working condition, and send the first control signal to the intelligent gateway module through the router.

[0038] Here, the working module obtains the operating status signal of the communication module, analyzes and processes the operating status signal, determines the current operating status of the ship, and thereby determines whether each wind turbine is turned on or off; and sends the first control signal for controlling the operating status of the wind turbine to the intelligent gateway module through the upper network.

[0039] The intelligent gateway module is used to convert the first control signal into a second control signal that can be recognized by the ventilation module, and send the second control signal to the ventilation module through the bus.

[0040] Here, the intelligent gateway module is used for protocol conversion, converting the lower layer network protocol into the upper layer TCP / IP protocol, and sending the converted second control signal to the ventilation module through the bus.

[0041] The ventilation module is used to control the operation of the fan group corresponding to the current ship operating condition according to the second control signal.

[0042] The wind turbine group is a collection of wind turbine units corresponding to different ship operating conditions; the first control signal and the second control signal include wind turbine group information and the operating status of the wind turbine units corresponding to the wind turbine group.

[0043] Here, the fans that need to be operated under each working condition are divided into a group. When the working conditions change, the fans are operated in groups through control signals, which simplifies the operating steps and greatly simplifies the operating steps for the crew.

[0044] The fan group is divided into a sailing condition fan group, a bow condition fan group and a stern condition fan group. The number of fan units in each fan group can be set according to actual conditions.

[0045] Specifically, refer to Figure 2 For example, a ro-ro ship operates at high speeds and has good natural ventilation conditions. Therefore, the four fans at the rear are turned on for ventilation. The ventilation level is marked "ON." E stands for mechanical ventilation, and N for automatic ventilation.

[0046] Reference Figure 3 During loading and unloading, the ship is stationary and the natural ventilation conditions are poor. When loading and unloading at the stern, that is, at the stern, it is necessary to turn on the four fans at the bow and the two fans at the stern.

[0047] Reference Figure 4 When the bow is loading and unloading, that is, in the bow operating condition, the 6 fans at the tail need to be turned on.

[0048] In one embodiment, reference Figure 5 The communication module 3 includes a host remote control system receiving unit 31, a channel equipment system receiving unit 32, a fire detection system receiving unit 33 and a carbon dioxide release alarm system receiving unit 34.

[0049] The main engine remote control system receiving unit is used to receive the forward signal and stop signal sent by the main engine remote control system.

[0050] The channel equipment system receiving unit is used to receive the bow door opening signal, bow door closing signal, stern door opening signal and stern door closing signal sent by the channel equipment system.

[0051] The fire detection system receiving unit is used to receive the fire alarm signal sent by the fire detection system.

[0052] The carbon dioxide release alarm system receiving unit is used to receive the carbon dioxide release signal sent by the carbon dioxide release alarm system.

[0053] In one embodiment, referring to Figure 5 The working module 4 includes an operation status judgment unit 41 and a control signal sending unit 42 which are connected to each other.

[0054] The operation status judgment unit is used to determine that the ship is in a navigation condition when a forward signal is received, and send the navigation condition signal to the control signal sending unit; when a stop signal, a bow door opening signal and a stern door closing signal are received, determine that the ship is in a bow loading and unloading condition, and send the bow condition signal to the control signal sending unit; when a stop signal, a bow door closing signal and a stern door opening signal are received, determine that the ship is in a stern loading and unloading condition, and send the stern condition signal to the control signal sending unit; when a fire alarm signal or a carbon dioxide release signal is received, send a closing signal to the control signal sending unit; wherein, the first control signal includes the navigation condition signal, the bow condition signal, the stern condition signal and the closing signal.

[0055] Here, when a fire breaks out in the cargo hold, all fans are shut down to prevent the fire from spreading. When CO2 is about to be released, all fans are shut down to prevent CO2 leakage.

[0056] The control signal sending unit is used to send the first control signal to the intelligent gateway module.

[0057] In one embodiment, referring to Figure 5 The ventilation module 1 further includes a main distribution board 12 connected to a fan unit 11 , and the fan unit includes a fan starter 111 , a time delay relay 112 and a fan 113 connected in sequence.

[0058] Main switchboard for supplying power to the fan units.

[0059] The main switchboard can also communicate with the communication module. When the cargo hold fans are numerous and powerful, the main switchboard sends an overload inquiry signal to the communication module, which in turn sends an alarm signal to the distribution network. If the grid's remaining power is insufficient, the distribution network system can start the backup generator first to avoid overloading the generator.

[0060] The fan starter is used to receive the second control signal sent by the intelligent gateway module, and judge the operating status of the fan corresponding to the fan starter according to the fan unit number and operating status in the second control signal. When the operating status is started, a start signal is sent to the delay relay; when the fan operating status is closed, a shutdown signal is sent to the fan.

[0061] The time delay relay is used to send a start signal to the fan according to a preset delay.

[0062] Here, since there are a large number of wind turbines and their power is large, if they are started at the same time, it will cause excessive transient voltage drop in the power grid, affecting the stability of the equipment. Therefore, a delayed start is adopted for the wind turbines. After one wind turbine is started, the second wind turbine is started after a short delay. This avoids the impact on the power grid caused by the start-up of all wind turbines.

[0063] In one embodiment, referring to Figure 5 The fan starter 111 includes an I / O module 114; the I / O module in each fan unit is connected in series to the intelligent gateway module through a bus.

[0064] Here, because each fan starter needs to be connected through a hard point, the number of cables is large. Including I / O modules in each starter and connecting them through a bus ring will greatly reduce the number of cables in the entire system.

[0065] The I / O module is used to receive the second control signal sent by the intelligent gateway module.

[0066] In one embodiment, referring to Figure 5 The fan unit further includes a damper 115, which is connected to the I / O module and the fan respectively.

[0067] When the damper is closed, a damper closing signal is sent to the I / O module.

[0068] The I / O module is also used to send the damper closing signal to the working module and the fan respectively to shut down the fan.

[0069] Here, the damper is normally open during normal operation. When it closes, it indicates a system failure. When the damper closes or fails, it sends a damper-closed or faulty signal to the I / O module. When the damper corresponding to a particular fan closes or fails, the fan is automatically shut down to prevent motor overload caused by the fan continuing to run after the damper closes.

[0070] In one embodiment, reference Figure 5 The device also includes a collection module 6, which is in communication with the router 2.

[0071] The acquisition module is used to obtain the ship cargo hold temperature and the ship cargo hold pressure difference, and send the ship cargo hold temperature and the ship cargo hold pressure difference to the working module through the router.

[0072] An embodiment of the present invention provides a cargo hold fan control device, comprising: a ventilation module, a router, and a communication module, a working module, and an intelligent gateway module respectively connected to the router for communication; wherein the ventilation module includes a plurality of fan units connected in series, and the intelligent gateway module is connected to the ventilation module through a bus; the communication module is used to obtain an operating status signal sent by a communication-connected peripheral system, and send the operating status signal to the working module through the router; the working module is used to judge the current ship operating condition according to the operating status signal, and generate a first control signal according to the ship operating condition, and send the first control signal to the intelligent gateway module through the router; the intelligent gateway module is used to convert the first control signal into a second control signal that can be recognized by the ventilation module, and send the second control signal to the ventilation module through the bus; the ventilation module is used to control the operation of the fan group corresponding to the current ship operating condition according to the second control signal; wherein the fan group is a collection of fan units corresponding to different ship operating conditions; the first control signal and the second control signal include fan group information and the operating status of the fan units corresponding to the fan group. In this method, the operating condition of the ship is judged by the operating status signal, and the corresponding fan in the pre-set wind turbine group is turned on according to the current operating condition, thereby realizing automatic switching of the fan operating status under different operating conditions, thereby ensuring the safe operation of the ship.

[0073] Example 2:

[0074] Figure 6 Schematic diagram of the cargo hold fan control system provided in Example 2 of the present invention.

[0075] Reference Figure 6 The cargo hold fan control system includes a remote control device 7 and the above-mentioned cargo hold fan control device 8.

[0076] Remote control device for controlling cargo hold fan control device.

[0077] Specifically, refer to Figure 7 and Figure 8 , the remote control device controls the cargo hold fan control device through the operation interface. There are two working modes in the operation interface. One is the automatic control mode, at this time the fan will automatically run according to the preset program, and can automatically control the start and stop of the fan according to the current working conditions, or control the corresponding fans in groups with one button. The other is the manual control mode, the crew can manually control any fan according to their needs. In addition, refer to Figure 9 The crew can also monitor the operating status of the wind turbine through the operation interface.

[0078] An embodiment of the present invention provides a cargo hold fan control system, comprising: a ventilation module, a router, and a communication module, a working module, and an intelligent gateway module respectively connected to the router for communication; wherein the ventilation module comprises a plurality of fan units connected in series, and the intelligent gateway module is connected to the ventilation module through a bus; a communication module for obtaining an operating status signal sent by a communication-connected peripheral system, and sending the operating status signal to the working module through the router; a working module for judging the current ship operating condition according to the operating status signal, and generating a first control signal according to the ship operating condition, and sending the first control signal to the intelligent gateway module through the router; the intelligent gateway module for converting the first control signal into a second control signal that can be recognized by the ventilation module, and sending the second control signal to the ventilation module through the bus; the ventilation module for controlling the operation of the fan group corresponding to the current ship operating condition according to the second control signal; wherein the fan group is a collection of fan units corresponding to different ship operating conditions; the first control signal and the second control signal include fan group information and the operating status of the fan units corresponding to the fan group.
