[0022] Figure 1 Schematic diagram of an oil and gas detection device for a ship engine room according to an embodiment of the present invention. Figure 1 As shown, an oil and gas detection device for a ship engine room provided by an embodiment of the present invention includes: a first alarm 10, arranged inside the ship engine room; a second alarm 20, arranged outside the ship engine room; a fan 30, used to connect the ship engine room and the external environment of the ship engine room; an oil and gas detector 40, used to detect the current oil and gas concentration in the ship engine room; an oil and gas monitoring box 50, electrically connected to the fan 30, the first alarm 10, the second alarm 20 and the oil and gas detector 40, the oil and gas monitoring box 50 is used to: obtain the current oil and gas concentration from the oil and gas detector 40, based on the current oil and gas concentration, a preset oil and gas concentration warning value and a preset oil and gas concentration alarm value, control the working states of the first alarm 10, the second alarm 20 and the fan 30, the oil and gas concentration warning value is less than the oil and gas concentration alarm value.

[0023] It should be noted that the oil and gas detector 40 can be one or more. In the case of more than one, the multiple oil and gas detectors 40 are respectively arranged at different positions in the ship's engine room. In addition, since the personnel on duty may be inside or outside the ship's engine room, if the alarm is only issued at one position, the personnel on duty may not find it. Therefore, the first alarm 10 is arranged inside the ship's engine room, and the second alarm 20 is arranged outside the ship's engine room, which reduces the possibility that the personnel on duty will not find the alarm information.

[0024] In some embodiments, the oil and gas monitoring box 50 is used to: if the current oil and gas concentration is less than the oil and gas concentration warning value, control the first alarm 10, the second alarm 20 and the fan 30 to be in the first working state; if the current oil and gas concentration is not less than the oil and gas concentration warning value, and the current oil and gas concentration is less than the oil and gas concentration alarm value, control the first alarm 10, the second alarm 20 and the fan 30 to be in the second working state to issue a warning; if the current oil and gas concentration is not less than the oil and gas concentration alarm value, control the first alarm 10, the second alarm 20 and the fan 30 to be in the third working state to issue an alarm.

[0025] Specifically, the current oil and gas concentration is less than the oil and gas concentration warning value, indicating that the oil and gas concentration in the ship's engine room is low and there is no safety risk, so the first working state may refer to the first alarm 10 being in the off state, the second alarm 20 being in the off state, and the fan 30 being in the off state. The current oil and gas concentration is not less than the oil and gas concentration warning value, and the current oil and gas concentration is less than the oil and gas concentration alarm value, indicating that the oil and gas concentration in the ship's engine room is low but there is a safety risk, so the second working state may refer to the first alarm 10 being in the on state, the second alarm 20 being in the on state, and the fan 30 being in the off state. The current oil and gas concentration is not less than the oil and gas concentration alarm value, indicating that the oil and gas concentration in the ship's engine room is high and there is a greater safety risk, so the third working state may refer to the first alarm 10 being in the on state, the second alarm 20 being in the on state, and the fan 30 being in the on state.

[0026] In some embodiments, reference Figure 2 As shown, the oil and gas detection device of the ship engine room may also include: a power supply component 60, connected to the oil and gas monitoring box 50; wherein the power supply component 60 may include: an external power supply 601; a filter 602, the input end of the filter 602 is connected to the external power supply 601; a protection circuit 603, the input end of the protection circuit 603 is connected to the output end of the filter 602; an AC / DC power supply module 604, the input end of the AC / DC power supply module 604 is connected to the output end of the protection circuit 603, and the output end of the AC / DC power supply module 604 is connected to the oil and gas monitoring box 50.

[0027] It should be noted that the external power supply 601 may be an AC220V power supply.

[0028] In some embodiments, the protection circuit 603 may include: a fuse 6031, the input end of the fuse 6031 is connected to the output end of the filter 602; a power switch 6032, the input end of the power switch 6032 is connected to the output end of the fuse 6031, and the output end of the power switch 6032 is connected to the input end of the AC / DC power module 604.

[0029] In some embodiments, reference Figure 3 As shown, the oil and gas detection device of the ship engine room may also include: a human-computer interaction component 70, which is arranged on the panel of the oil and gas monitoring box 50; wherein the human-computer interaction component 70 may include: a display 701, which is electrically connected to the oil and gas monitoring box 50, and is used to display the current oil and gas concentration and query the alarm record; a button 702, which is electrically connected to the oil and gas monitoring box 50, and is used to set the oil and gas concentration warning value, the oil and gas concentration alarm value and the system time of the oil and gas monitoring box 50.

[0030] In some embodiments, the human-machine interaction component 70 may further include: an indicator light 703 electrically connected to the oil and gas monitoring box 50 for indicating whether the button 702 is pressed.

[0031] In some embodiments, the oil and gas detection device of the ship engine room may also include: a first intermediate relay 80, the oil and gas monitoring box 50 is electrically connected to the first alarm 10 through the first intermediate relay 80; a second intermediate relay 90, the oil and gas monitoring box 50 is electrically connected to the second alarm 20 through the second intermediate relay 90.

[0032] It should be noted that the display 701 can be a 7-inch true color LCD screen, the first alarm 10 can be an audible and visual alarm, the second alarm 20 can be an audible and visual alarm, the audible and visual alarm can be a BBJ-ZR explosion-proof audible and visual alarm, and when the gas alarm controller sends out an alarm signal, the audible and visual alarm sounds. The oil and gas detector 40 can be a GN8010-C point-type combustible gas detector, equipped with a dedicated gas sensor component, using a catalytic combustion method to detect various oils and gases in the cabin, and the detector sends the oil and gas concentration value to the oil and gas monitoring box 50 in a CAN bus communication method.

[0033] It should be noted that during the navigation or use of the ship, energy is constantly converted and transmitted, and the energy loss during this period is manifested in the form of heat energy, which causes the temperature inside the cabin filled with fuel or lubricating oil to rise, and the fuel or lubricating oil volatilizes more due to the temperature increase, and the engine room is in a dangerous state. In order to avoid explosions due to excessive oil and gas concentration, it is necessary to monitor the oil and gas in the engine room in real time. In the past, the oil and gas detection equipment used relay control and could not display the cabin concentration in real time, and the monitoring was unreliable. The sensor often broke the line, malfunctioned to start the fan 30, or could not detect the concentration, resulting in the fan 30 not being turned on, causing panic to the crew and affecting the cabin safety. The embodiment of the present invention solves the problems that the previous ship oil and gas monitoring technology generally cannot monitor in real time, is unstable, and is unsafe, and provides a more accurate automated oil and gas monitoring, alarm, and automatic exhaust system. Through forecasting and early processing, the safety hazards of excessive oil and gas concentration in ships are fundamentally eliminated, serious consequences are avoided, and important guarantees are provided for the safe operation of ships.

[0034] It should be noted that the oil and gas monitoring box 50 also includes: a box shell and a control circuit board. The box shell is made of aluminum alloy. The control circuit board is the core acquisition and control component of the oil and gas monitoring box 50, responsible for data acquisition, calculation, communication and output control in conjunction with the intermediate relay.

[0035] It should be noted that the oil and gas detection device in the ship's engine room uses a single-chip microcomputer as the central processor, and realizes data interaction with the oil and gas detector 40 through the CAN communication interface of the control circuit board, summarizes the concentration values ​​collected by the oil and gas detectors 40 at various positions, and generates sound and light alarms according to the pre-set oil and gas concentration warning value and oil and gas concentration alarm value, and uses a 7-inch true color LCD screen to display the current cabin concentration and status, and can set the oil and gas concentration warning value, oil and gas concentration alarm value and system time through the button 702 on the panel, and can query the alarm record on the LCD screen. It solves the need for real-time monitoring of cabin oil and gas concentration, monitors the oil and gas concentration in the cabin in real time, and accurately and promptly alarms when the concentration exceeds the standard, and automatically turns on the fan 30, which improves the stability and reliability of oil and gas monitoring, ensures the safety of all ship personnel, and has a high market value. In addition, an aluminum alloy closed box is used, and the metal shell is connected to the ground to better eliminate electromagnetic interference; the internal component layout and routing try to place the components related to the power input signal and the output signal near the corresponding port to avoid interference caused by the coupling path; the signal line is as short and straight as possible, and try not to form a loop to cause radiation; the signal line and the power line are separated and routed without bundling together; the equipment shell is made of high-quality aluminum alloy, the outer surface of the equipment shell is painted, and the metal parts are all anti-corrosion coated; the insulation material is durable, flame retardant, moisture-resistant, mildew-resistant and oil-mist-resistant. In addition to using wire rope shock absorbers to reduce shock to the box, the equipment also uses isolation and buffering methods to protect the inside of the equipment, and the internal structure of the equipment is mainly reinforced to improve the rigidity of the mechanism to reduce resonance.

[0036] It should be noted that the oil and gas detection device in the ship's engine room uses the single-chip microcomputer ARM7 (Cortex-M3) as the central processor installed in the control circuit board, and realizes data interaction with the oil and gas sensor through the CAN communication interface of the control circuit board.

[0037] The oil and gas detection device of the ship engine room of the embodiment of the present invention comprises: a first alarm 10, which is arranged inside the ship engine room; a second alarm 20, which is arranged outside the ship engine room; a fan 30, which is used to connect the ship engine room and the external environment of the ship engine room; an oil and gas detector 40, which is used to detect the current oil and gas concentration of the ship engine room; an oil and gas monitoring box 50, which is electrically connected to the fan 30, the first alarm 10, the second alarm 20 and the oil and gas detector 40, and the oil and gas monitoring box 50 is used to: obtain the current oil and gas concentration from the oil and gas detector 40, and control the working state of the first alarm 10, the second alarm 20 and the fan 30 based on the current oil and gas concentration, the preset oil and gas concentration warning value and the preset oil and gas concentration alarm value, and the oil and gas concentration warning value is less than the oil and gas concentration alarm value. In the case that the current oil and gas concentration of the ship engine room is too high, the oil and gas monitoring box 50 controls the working state of the first alarm 10, the second alarm 20 and the fan 30 to realize the alarm and exhaust through the fan 30, so as to improve the safety of personnel in the ship engine room.
