All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0018] like Figure 1 As shown, a smart safety monitoring system for ro-ro ships entering and leaving ports includes a central control unit, a bridge operation unit, and a local operation unit at the ship's landing point. The local operation unit includes a system activation module, a system shutdown module, and an alert module. The system activation module and the system shutdown module are used to activate and deactivate the ship-to-shore information transmission system, respectively. The bridge operation unit includes a system activation display module, a system shutdown display module, and an activation alert module. The system activation module is digitally connected to the system activation display module via a cable from the central control unit. The system shutdown module is digitally connected to the system shutdown display module via a cable from the central control unit. The activation alert module is digitally connected to the alert module via a cable from the central control unit. The number of system activation display modules is set according to the actual number of stations on the ship. In some embodiments, the bridge operation unit is an operable display.
[0019] The system works as follows: 1) When the ship arrives at the wharf, each station connected to the wharf, the loading and unloading personnel will activate the system by pressing the system activation module on the ship entry point local operating unit, which will be displayed on the bridge operating unit, and the system activation display module corresponding to the wharf will give a display, in some embodiments, the system activation display module is an indicator light, which indicates that loading or unloading can be carried out at this time; 2) After the loading and unloading operation is completed, the roll-on / roll-off ship ramp is cleaned, and the deck and gate are closed, the corresponding loading and unloading personnel will deactivate the system by operating the system shutdown module on the ship entry point local operating unit, and the central control unit receives the system shutdown signal and conveys the information to the bridge that the ship-shore operation has been completed, at this time, the system shutdown display module in the bridge operating unit gives a display. In some embodiments, the system shutdown display module is an indicator light.
[0020] 3) After the ship-shore cleaning is completed, the driver will operate the activation warning display module on the bridge operating unit, at this time, all warning modules on the wharf display a warning signal, which means that the ship is about to sail.
[0021] In some embodiments, the warning module is a red flashing light and a sound alarm bell installed at each ship entry point, the red flashing light flashes and the alarm bell gives a 30-second alarm sound.
[0022] Further, the central control unit includes a signal receiving module, a PLC signal processing module, a power module, a signal output module and a system fault monitoring module, the signal receiving module and the signal output module are used to receive and transmit signals to the bridge operating unit and the ship entry point local operating unit, the system fault monitoring module is used to monitor the fault of the power module and alarm to the ship alarm system.
[0023] The central control unit is the core controller of the roll-on / roll-off ship port entry and exit intelligent safety system, which receives and transmits signals through the internal modules and the PLC signal processing module to control and monitor the entire system, the power supply of the unit comes from the normal power supply or the emergency power supply, the normal power supply and the emergency power supply are automatically switched, and the power failure and system common failure alarm can be sent to the ship alarm system.
[0024] Further, the bridge operating unit further includes a fault indication module, which is in communication connection with the system fault monitoring module, and is used to indicate any fault alarm of the system. In some embodiments, the fault indication module is a flashing light.
[0025] Further, the ship docking point local operation unit is also provided with a buzzer, and the cab operation unit is also provided with an all-call module, which is in communication connection with the buzzers of all the ship docking point local operation units. The all-call module is used for communication between the cab and all the docking points on the wharf, and specifically, selection of the all-call module on the cab operation unit will activate the buzzers of all the ship docking point local operation units to emit beeping sounds.
[0026] In this way, when the crew in the cab is preparing to leave the wharf or is approaching the wharf, the all-call module is operated to inform the crew near the local operation panel.
[0027] Further, the cab operation unit also includes a system activation module and a stop loading and unloading warning module, the system activation module is in communication connection with the ship docking point local operation unit through the central control unit, and the stop loading and unloading warning module is in communication connection with the flashing light and the sound alarm bell through the central control unit. In this way, communication with all the docking points on the wharf can be achieved to indicate that there is an emergency, which will be realized through the local flashing light and the sound alarm bell.
[0028] When the ship arrives at the wharf and needs to unload, the crew in the cab can start the system activation module on the cab operation unit to activate the system and inform that the unloading procedure is about to start; when the ship needs to load from the wharf, the crew near the local operation unit starts the system activation module on the local operation panel to activate the system and inform that the loading procedure is about to start.
[0029] Further, the cab operation unit is also provided with an automatic port module, a manual port module and a buzzer, the automatic port module and the manual port module can both be connected with the full-ship fire alarm system on the deck to transmit signals to close the smoke detector on the deck; the system activation module in the ship docking point local operation unit is in communication connection with the automatic port module and the buzzer in the cab operation unit.
[0030] It should be noted that when the automatic port module is selected, only the smoke detector is automatically inhibited, and when the system is deactivated, the smoke detector is automatically released.
[0031] When the automatic port mode is selected, the smoke detection sensor on the deck will be inhibited to avoid unnecessary alarm caused by vehicle exhaust.
[0032] When the manual port mode is selected, the smoke detectors on the deck will be disabled. The smoke detectors are wired to the bridge operator panel. It is noted that the manual port mode setting should have the ability to be reset by again pressing the same button on the bridge operator panel; with the reset function, the smoke detectors on the deck will be reactivated.
[0033] When the system activation module on the ship access point local operation unit is selected, the indicator light on the ship access point local operation unit is illuminated. At this time, the automatic port mode is activated, and the smoke detection sensors on the deck will be suppressed to avoid unnecessary alarms caused by vehicle exhaust.
[0034] At the same time, the corresponding activation display module on the bridge operator unit is illuminated, and the buzzer on the bridge operator unit is activated.
[0035] When the system activation module on the ship access point local operation unit is released, the automatic port mode will be canceled, which will reactivate the smoke detector sensors on the deck, and the indicator light on the ship access point local operation unit of the corresponding site will be extinguished.
[0036] Although embodiments of the present application have been shown and described, it is to be understood that various modifications- alterations- substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
