It is a block diagram which shows an operation part concretely.

1 to 3, the emergency generator control system according to the present invention includes a display unit 180, a control unit 100, an operation unit 160, an interface module 110, an analog expansion unit 130, and a relay module ( 140, an expansion relay 150, and an emergency power generation device 120.

In detail, the emergency power generation device 120 may include an engine 121, a power generation unit 122, a power control unit 123, and a sensor unit.

The engine 121 uses an engine that uses fossil fuel, such as a diesel engine. The engine compresses the air inside the cylinder to generate the rotational force generated by burning heavy oil or light oil.

The power generation unit 122 generates electric power using the rotational force from the engine 121.

The power control unit 123 controls the power produced by the power generation unit 122 and converts the power to be used in the ship.

The sensor unit may include a plurality of sensors such as a pickup sensor, a temperature sensor, and a pressure sensor. Pick-up sensor is a sensor that uses the principle that induced electromotive force is generated by the electromagnetic induction phenomenon when the magnetic flux passes through the pickup coil. The pickup sensor is provided inside the engine 121 to measure the RPM of the engine 121. The pickup sensor generates a square wave by connecting a constant magnet to the crankshaft and measuring a change in magnetic flux generated each time the engine rotates. The pickup sensor counts the number of square waves and provides them to the controller 100.

The temperature sensor may include a first analog sensor for sensing a lubricating oil temperature and a second analog sensor for sensing a coolant temperature. The pressure sensor may include a third analog sensor for detecting lubricating oil pressure and a fourth analog sensor for detecting coolant pressure.

The first analog sensor may detect a temperature in the range of -50 to 200 ° C. The first analog sensor may use MBT 5250 manufactured by DANFUSS. At this time, the first analog sensor is input in the form of 0.6 ~ 3V. The value converted to 12bit resolution can be calculated based on the minimum 0.6 and 3V, and the sensed value can be filtered and provided to the controller.

The second analog sensor can detect a temperature in the range of 0 ~ 120 ℃. As the second analog sensor, W227 may be used, such as TR227. The temperature sensor has an analog output of 4-20mA and a full voltage of 24V.

The third analog sensor may sense pressure in the range of 1 to 10 bar, and the fourth analog sensor may sense pressure in the range of 1 to 10 bar.

The values detected by the first to fourth analog sensors are transmitted to the controller 100.

The sensor unit may further include a power supply voltage sensor for sensing a system power supply voltage. The supply voltage sensor can detect voltages in the 0 to 30V range. The voltage value measured by the power supply voltage sensor is transmitted to the controller 100.

The third and fourth analog sensors may use PA-221SR manufactured by KELLER.

The controller 100 controls the engine propulsion force inside the generator, and controls the general setting. The controller 100 monitors the thrust force or general setting of the generator.

To this end, the controller 100 receives a signal from the engine inside the generator through the interface module 110. The controller 100 generates a control signal through the received signal and transmits the generated control signal to the relay module 140. In addition, the controller 100 transmits state information of the engine to the display unit 180.

The controller 100 may be implemented as a control board adopting a high speed multifunction digital signal processing processor to be flexible and user accessible in engine control.

The digital signal processing processor of the controller 100 includes a digital input terminal, an analog sensor signal input terminal and a 4-20 mA current output terminal, a pickup sensor input terminal, a relay control terminal, a sensor signal input terminal, a monitoring signal output terminal, and an RS-232C. It may include an input / output terminal such as a communication port. The digital signal processing processor of the controller 100 processes a signal input to each terminal and provides a result signal to the interface module 110, the display unit 180, the relay module 140, and the like.

The controller 100 may calculate the engine speed. That is, when the engine speed information is received from the pickup sensor included in the emergency power generation device 120, it may be calculated and provided to the display unit 180.

The controller 100 may receive the current engine speed and calculate the received engine speed, display the calculated speed on the display unit 180, or store it if necessary. The input spherical pulse is calculated using the capture interrupt. The RPM calculation is as in Equation 1. Since the number of pulses per revolution is different for each pickup coil of an engine, it is easy to apply it to other engines simply by adjusting this pulse value parameter.

Each time the capture interrupt occurs, the timer value received is calculated and stored in the buffer. Due to the nature of the capture interrupt, it is desirable to be configured not to receive a frequency input below a specific frequency, about 100 Hz, because it waits for the next input.

The controller 100 may include an A / D converter dedicated to signal processing.

The A / D converter may convert analog signals input from sensors installed in the engine into digital signals. The A / D converter receives 0-3V analog input voltage and outputs it after digital conversion. A / D converter according to an embodiment of the present invention is composed of a module having two eight channels, it can be configured in 16 channels in series. It may include an analog multiplexer, sample and hold (S / H), high speed prescaler, result register, A / D converter control register, and the like.

A / D converters can perform simultaneous or sequential sampling and can provide fast conversion rates of 25 MHz or 12.5 MSPS. The auto sequencing capacity can provide up to 16 automatic conversions in a single session, with each conversion programmable from 1 to 16 selected inputs. The A / D converter then stores the conversion value in the result register.

A / D converters can provide a variety of triggers for Start of Conversion (SOC).

The controller 100 may include a storage unit that stores a signal input from the sensor unit.

The storage unit may store information about the engine, such as engine speed information, alarm information, lubricant temperature and pressure information, coolant temperature and pressure information, battery information, and engine stop information.

The engine information stored in the storage may be managed as a database. For example, the controller 100 may be connected to an external PC 170 through an RS232 communication method to transmit information about an engine to a computer.

The transmitted information may be displayed in a table as shown in Table 1. The storage unit may use a memory such as a flash memory.

The interface module 110 is connected to the power supply unit, the control unit 100, the operation unit 160, and the emergency power generator 120. The interface module 110 may be composed of a plurality of switch elements, and may provide a signal input from each component to the controller 100 and a signal input from the controller 100 to each component.

The interface module 110 may include a 24V power supply, twelve digital inputs and five analog inputs, six relay inputs and outputs, and two pickup terminals.

The interface module 110 may be connected to a main power battery and an auxiliary power battery to supply power.

As shown in FIG. 3, the operation unit 160 includes a power supply 161, a start 162, a stop 163, a bell stop 164, an alarm reset 165, an emergency stop 165, and an automatic / manual mode. 166 may be provided.

The power button 161 is a button for supplying power to the emergency power generating device. When the power button 161 is pressed, the emergency power generating device is driven.

When the start button 162 is not automatically set as a button for starting the engine of the emergency power generator, the start button 162 is manually pressed to start the engine.

The stop button 163 may stop the engine 121. The stop button 163 may be pressed by the user when the emergency power generation device is unnecessary to operate.

The bell stop button 164 is a button for stopping the alarm bell ringing by the user pressing a button after the operator or the user takes appropriate measures after the alarm bell rings or after the alarm bell is recognized.

The alarm reset button 165 is a button for resetting all alarms. For example, the alarm reset button 165 transmits a signal for alarm reset to the relay module 140 to turn off the relay circuits related to the alarm occurrence in the relay module 140.

The emergency stop button 166 may be operated by a user as a button for supplying a control signal to emergency stop the engine when an engine abnormality occurs.

The analog extension 130 may be connected to sensors that are not connected to the interface module 110 in the sensors installed in or around the engine. The analog expansion unit 130 may be connected to the control unit 100 to transmit an analog sensor signal to the control unit 100.

The relay module 140 may include seven relays for driving an emergency generator engine.

Hereinafter, the functions of each relay of the relay module will be described with reference to Table 2.

Relay number function Remarks First relay circuit Engine start and crank start Off when RPM is applied Second relay circuit Fuel valve opening and closing Engine stops when valve closes Third relay circuit Start failed Engine fails to start Fourth relay circuit Remote on Remote operation Fifth relay circuit Alarm bell Alarm ringing Sixth relay circuit Engine overspeed detection Engine speeding 7th relay circuit Each alarm display Alarm display

Table 2 summarizes the functions and control of each relay circuit of the relay module.

The first relay circuit drives the start motor of the engine. When the engine is started, the starter motor must be turned off immediately to protect the engine because the engine has more speed and power than the motor. That is, when the RPM signal indicating that the engine is started is input, the first relay circuit should be turned off immediately. To start the engine, the engine fuel valve must be opened as well as the start motor. Thus, the second relay circuit drives the fuel valve of the engine. When the engine is started, the first relay circuit is turned off and the second relay circuit remains on.

Here, engine starting can be attempted several times. In the present invention, three attempts will be described as an example. When a signal for starting the engine is input, the first relay circuit is turned on for 5 seconds, and if the engine RPM signal is not applied, it is turned off for 5 seconds and then turned on again for 5 seconds. This operation is performed three times. Accordingly, the maximum time for starting the engine is 25 seconds.

At this time, the third relay circuit is turned on when the engine drive fails as a result of three consecutive engine starts, thereby notifying the outside of the engine start failure. Here, the external may mean the display unit 180 or an alarm device for notifying the alarm. When the engine fails to start, the fifth relay circuit may be operated to ring the alarm bell.

The fourth relay circuit shows that the remote mode is set, and the sixth relay circuit notifies that the engine is rotating at an engine over speed, that is, 1980 RPM or more. The sixth relay circuit transmits a signal to the fifth relay circuit to automatically stop the engine when the engine is in an overspeed state and to operate an alarm bell notifying the outside (display unit or alarm device) of the overspeed. The seventh relay circuit informs the alarm state of the engine. When the controller is powered on and there is no alarm, the seventh relay circuit is turned on and is turned on by using the trigger signal whenever various alarms are received, indicating that an alarm condition of the engine has occurred to the outside.

The expansion relay 150 includes relay circuits which are preliminarily attached for engine control in addition to each function. For example, the expansion relay 150 may include a relay circuit which is operated when the lubricating oil temperature, the pressure of the engine, and the temperature or the pressure of the coolant is higher than the reference value to stop the engine or adjust the engine speed. .

The display unit 180 displays a state of the emergency power generation device. The display unit 180 may include a display device such as a liquid crystal display, a touch screen, or an organic light emitting display. The display unit 180 may display a state of an engine, that is, an engine RPM, an analog sensor signal, or a state of various alarms. 4 to 6 are exemplary embodiments illustrating a state of the emergency power generation device of the display unit 180. The display unit 180 displays four analog sensor values and displays the values in a chart, and the power supply values are the same. The display unit 180 lists important alarms on the left side and informs the user when an alarm occurs. In addition, the display unit 180 may display a manual, a remote mode display, and a state of preparation, operation, start, and failure, which are driving states of the engine.

4 is a diagram illustrating that an engine start signal is applied through a first relay circuit.

As shown in FIG. 4, the display unit 180 may display that an engine start signal is applied.

5 is a diagram illustrating that a stop signal is applied when an engine is stopped displayed on the display unit 180. As shown in FIG. 5, the stop signal when the engine is stopped may be displayed on the display unit 180.

6 is a screen displayed when the engine speed alarm and the bell alarm signal are generated on the display unit 180. As illustrated in FIG. 6, the display unit 180 may display an engine overspeed alarm and a bell alarm signal.

7 is a flowchart schematically illustrating a monitoring method of an emergency power generation device according to an embodiment of the present invention.

Referring to FIG. 7, the monitoring method of the emergency power generation apparatus according to the present invention includes a power-on step S10, an engine starting step S20, an engine speed measuring step S30, an engine speed comparing step S40, and an engine. An overspeed alarm bell ringing step (S50) and the step of displaying on the display unit (S60).

Specifically, the power-on step (S10) is a step of supplying power to the emergency power generation device, the display unit and the emergency power generation peripheral device for monitoring the emergency power generation device. At this time, a voltage of 24V is applied to the power supply. Here, an alarm is generated when the applied voltage is below a reference voltage, for example, 20V.

Next, in step S20 of starting the engine of the emergency power generation apparatus, pressing the start button of the operation unit or remotely controlling the engine may be performed by the emergency power generation apparatus. At this time, the engine may be started using a relay circuit. Here, the relay circuit may stop the engine and generate an alarm when the engine start attempt exceeds a predetermined value, for example, three times.

Next, the engine speed measurement step (S30) measures the engine speed in the pickup sensor inside the engine. The pickup sensor generates a square wave corresponding to the engine speed and transmits the generated square wave signal to the controller. The engine speed may generate a square wave having a voltage of 0 to 3 V set per revolution. In this case, the pickup sensor may generate an analog signal and transmit the analog signal to the interface module or the analog expansion unit.

Next, the signal corresponding to the engine speed received from the pickup sensor is converted into a digital signal by the control unit.

At this time, the engine speed measurement step (S30) may receive a signal sensed from other sensors installed in or around the engine. The sensing signal may be lubricant temperature and pressure information, and may be coolant temperature and pressure information.

Here, the controller compares the digital signal with a reference value (S40). The reference value may be stored in a storage unit and compares the stored reference value with a digital signal. The reference value may be a value in which the rotation speed of 1800 to 2100 RPM is converted into a pulse signal.

On the other hand, an external interrupt setting step may be further included before starting the engine of the emergency power generator (S20). For example, the monitoring system of the emergency power generation device determines whether the current automatic mode or manual mode at a predetermined time, and allows an external interrupt to enable remote operation in the automatic mode. However, in the manual mode, external interrupt cannot be set. At this time, the monitoring system of the emergency power generation device may be set at a time interval of 1 to 10ms.

Subsequently, in step S60 of displaying the engine speed on the display, information about the engine speed digitally converted by the controller 100 is displayed on the display. At this time, the lubricating oil temperature and pressure information, and the coolant temperature and pressure information can be displayed.

In addition, information about sensing signals received from other sensors may be displayed on the display. For example, information about a power supply voltage can be displayed.

As shown in FIG. 7, when the engine speed is equal to or greater than the reference value, the engine overspeed alarm bell rings step S50 to notify the engine overspeed. At this time, the relay circuit is driven to ring the alarm bell, the alarm bell information is stored in the storage of the controller.

According to the present invention, a program of instructions that can be executed by the monitoring system of the emergency power generation device is implemented to perform the monitoring method of the emergency power generation device of the ship shown in FIG. 7, and is read by the monitoring system of the emergency power generation device. It is possible to provide a recording medium on which the program can be recorded.

That is, the monitoring method of the emergency power generation apparatus according to the embodiment of the present invention may be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer readable medium. Computer-readable media may include, alone or in combination with the program instructions, data files, data structures, and the like.

The program instructions recorded on the computer readable medium may be those specially designed and constructed for the present invention, or may be known and available to those skilled in the computer software arts. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tape, optical media such as CD-ROMs, DVDs, and magnetic disks, such as floppy disks. Hardware devices specially configured to store and execute program instructions such as magneto-optical media and ROM, RAM, flash memory and the like. In addition, the above-described medium may be a transmission medium such as an optical or metal wire, a waveguide, or the like including a carrier wave for transmitting a signal specifying a program command, a data structure, and the like. Examples of program instructions include not only machine code generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like.

The hardware device described above may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims.
