DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The core of the present invention is to provide a monitoring system for diesel engine drive interlock, which can effectively extend the service life of the diesel engine. Another core of the present invention is to provide a control method suitable for the above diesel engine drive interlock monitoring system.

[0043] Please refer to Figure 1 The present invention provides a monitoring system for diesel engine drive interlock, comprising a detection component, a start button 1 and a controller. The detection component is used to detect the speed, lubricating oil pressure, fresh water pressure, supercharger lubricating oil pressure, fuel pressure and working state of the cranking mechanism of the diesel engine; the start button 1 is used to control the start of the diesel engine; the controller signal connects the detection component and the start button 1, and is used to control whether the start signal output by the start button 1 is invalid or not according to the detection result of the detection component.

[0044] The monitoring system is equipped with a detection component to detect the speed, lubricating oil pressure, fresh water pressure, supercharger lubricating oil pressure, fuel pressure and the working state of the cranking mechanism of the diesel engine in real time. For example, preferably, an oil pressure sensor and a water pressure sensor are added to the diesel engine. Specifically, oil pressure sensors are provided in the oil circuit flowing to the combustion chamber inside the diesel engine, the branch lubricating oil circuit flowing to the supercharger, and the main branch lubricating oil circuit flowing to the diesel engine to detect the fuel pressure of the diesel fuel, the supercharger lubricating oil pressure and the lubricating oil pressure respectively. A water pressure sensor is provided in the air intake duct of the diesel engine to detect the fresh water pressure inside the diesel engine. A speed sensor is provided around the crankshaft of the diesel engine to detect the speed of the diesel engine. A position detector is provided at the start switch of the cranking mechanism to detect the position of the above-mentioned start switch in real time, so as to know whether the start switch is pressed or popped up, so as to know the working state of the cranking mechanism. Of course, the arrangement of the detection component is not limited to the above-mentioned example types, as long as the above-mentioned functions can be achieved.

[0045] Correspondingly, the monitoring system is also equipped with a start button 1, and the controller is used to receive and make judgments to control the on-off of the circuit between the start button 1 and the start switch of the diesel engine. Specifically, when the circuit between the start button 1 and the start switch of the diesel engine is turned on, the start-stop signal output by the start button 1 can be transmitted to the start switch of the diesel engine. Conversely, when the circuit between the start button 1 and the start switch of the diesel engine is disconnected, the start-stop signal output by the start button 1 cannot be transmitted to the first relay, that is, it is invalid. With such a setting, the monitoring system can effectively improve the operating stability and safety of the diesel engine and extend the service life of the diesel engine.

[0046] On the basis of the above-mentioned embodiment, it also includes a speed display 2 for displaying the speed of the diesel engine, a lubricating oil pressure display 3 for displaying the lubricating oil pressure, a fresh water pressure display 4 for displaying the fresh water pressure, a supercharger lubricating oil pressure display 5 for displaying the supercharger lubricating oil pressure, a fuel pressure display 6 for displaying the fuel pressure and a cranking interlock indicator 7 for indicating the working state of the cranking mechanism; the speed display 2, the lubricating oil pressure display 3, the fresh water pressure display 4, the supercharger lubricating oil pressure display 5, the fuel pressure display 6 and the cranking interlock indicator 7 are connected to the corresponding detector signals in the detection component.

[0047] like Figure 1 As shown, the monitoring system is equipped with a speed display 2, a lubricating oil pressure display 3, a fresh water pressure display 4, a supercharger lubricating oil pressure display 5, a fuel pressure display 6 and a cranking interlock indicator 7, so as to display the detected speed, lubricating oil pressure, fresh water pressure, supercharger lubricating oil pressure, fuel pressure and working status of the cranking mechanism of the diesel engine through the above-mentioned displays and indicators, and provide them to the operator for reference, so that the operator can manually judge whether the above-mentioned parameters meet the diesel engine starting standard, so as to choose whether to press the start button 1, so as to double-guarantee the safe and stable operation of the diesel engine and facilitate the operator to observe the real-time working condition of the diesel engine.

[0048] On the basis of the above embodiment, it further comprises a start-up permission indicator 8, which is used to output a start-up permission instruction when the detection result of the detection component meets the start-up standard.

[0049] like Figure 1 As shown, the start-allowed indicator 8 signal is connected to the controller so that after the controller receives the test result of the detection component, it can determine whether the current test result meets the start-up standard of the diesel engine. Then, after the start-up standard is met, the start-allowed indicator 8 transmits the start-allowed information to facilitate the operator to control the start of the diesel engine through the start button 1.

[0050] It should be noted that there is no limitation on the types of the above-mentioned speed display 2, lubricating oil pressure display 3, fresh water pressure display 4, supercharger lubricating oil pressure display 5, fuel pressure display 6, cranking interlock indicator 7 and start permission indicator 8, as long as the above-mentioned functions can be achieved. For example, the above-mentioned limiters can adopt digital displays or pointer displays, etc., and the above-mentioned indicators can adopt indicator lights or buzzers, etc.

[0051] On the basis of the above embodiment, the controller includes an associated switch, which is used to be arranged between the start button 1 and the start switch of the diesel engine for its own start and stop, to control the on and off of the circuit between the start switch and the start button 1, and the associated switch signal is connected to the detection component.

[0052] A diesel engine is usually provided with a start switch, which controls its own start or stop. The start button 1 is electrically connected to the start switch for controlling the start and stop of the diesel engine, so as to control whether the start switch is energized by pressing the start button 1. In the controller, the associated switch can be a relay or an electromagnetic switch, etc., and the associated switch is arranged on the circuit between the start button 1 and the start switch, and the component for receiving and processing the detection result in the controller is electrically connected to the associated switch, so as to receive and judge the detection result of the detection component through the controller, so as to control the opening and closing of the associated switch according to the result of the detection component, so as to disconnect or conduct the circuit between the start switch and the start button 1.

[0053] On the basis of the above embodiment, it also includes a monitor housing 9; the controller is arranged inside the monitor housing 9; the button part of the start button 1 is movably arranged on the top plate of the monitor housing 9; the display structure of the speed display 2, the display structure of the lubricating oil pressure display 3, the display structure of the fresh water pressure display 4, the display structure of the supercharger lubricating oil pressure display 5, the display structure of the fuel pressure display 6 and the display structure of the cranking interlock indicator 7, and the display structure of the start permission indicator 8 are all arranged on the top plate of the monitor housing 9; and the monitor housing 9 is provided with a wiring terminal 10, the plug-in end of the wiring terminal 10 extends out of the outside of the monitor housing 9, and the wiring end of the wiring terminal 10 is located inside the monitor housing 9, and is connected to the corresponding start button 1, cranking interlock indicator 7, speed display 2, lubricating oil pressure display 3, fresh water pressure display 4, supercharger lubricating oil pressure display 5, and fuel pressure display 6 through the cable signal located inside the monitor housing 9.

[0054] like Figure 1As shown, the top plate of the monitor housing 9 is provided with the above-mentioned displays and indicators for outputting a display structure of the detection signal, so that the operator can learn the various parameters of the diesel engine and the working status of the cranking mechanism through it, and the button part of the start button 1 for manual pressing extends to the outside through the top plate of the monitor housing 9, so that the operator can press the button part to start the diesel engine. With this arrangement, the monitoring system has strong integration and integrity and is easy to use.

[0055] Furthermore, if Figure 2 As shown, in order to reduce the difficulty of wiring, a wiring terminal 10 is set on the side wall of the monitor housing 9, and the wiring end of the wiring terminal 10 extends into the inner cavity of the monitor housing 9, so as to facilitate wiring inside the monitor housing 9 to connect the start button 1, the turning gear interlock indicator 7 and each display; correspondingly, the plug-in end of the wiring terminal 10 extends to the outside of the monitor housing 9, so that the operator can plug the cable connector to connect the detection component and the start switch. This arrangement enhances the structural compactness and integrity of the monitoring system and is easy to use.

[0056] It should be noted that the type and number of the connection terminals 10 are not limited, as long as the turning interlock indicator 7 and each display can be electrically connected to the corresponding detector, and the start button 1 can be electrically connected to the start switch.

[0057] On the basis of the above embodiment, the number of the speed display 2 and the lubricating oil pressure display 3 are both two, and the signals of the two speed display 2 are connected to the corresponding detectors for detecting the speed of the diesel engine, and the signals of the two lubricating oil pressure display 3 are connected to the corresponding detectors for detecting the lubricating oil pressure.

[0058] like Figure 1 As shown, in this embodiment, two speed displays 2 and two lubricating oil pressure displays 3 are provided, and two detectors for detecting the speed of the diesel engine and two detectors for detecting the lubricating oil pressure of the diesel engine are provided on one side of the diesel engine. The signals of the two detectors for detecting the lubricating oil pressure of the diesel engine are respectively connected to one speed display 2, and the signals of the two detectors for detecting the speed of the diesel engine are respectively connected to one lubricating oil pressure display 3, so as to realize double detection and effectively improve the operating safety of the diesel engine.

[0059] On the basis of the above embodiment, the detection component includes a first detector for detecting the speed of the diesel engine, a second detector for detecting the lubricating oil pressure of the diesel engine, a third detector for detecting the fresh water pressure of the diesel engine, a fourth detector for detecting the lubricating oil pressure of the diesel engine supercharger, a fifth detector for detecting the fuel pressure of the diesel engine and a sixth detector for detecting the working state of the diesel engine cranking mechanism; the first detector, the second detector, the third detector, the fourth detector, the fifth detector and the sixth detector are all arranged on the diesel engine, that is, each detector is arranged on the diesel engine to provide a new type of diesel engine. It should be noted that the installation method of each detector is not limited as long as the above detection function can be achieved. For example, a flange seat is processed on the diesel engine casing to install the detector through the flange structure. When it is necessary to measure the pressure of oil or water in the internal channel, a corresponding detection channel is opened on the diesel engine casing so that the detection end of the detector can extend into the corresponding channel inside the diesel engine.

[0060] With such arrangement, when in use, it is only necessary to electrically connect the free ends of the cables connected to each detector and the cables connected to the start switch to the corresponding wiring terminals 10, which is helpful to reduce the difficulty of installing the monitoring system.

[0061] On the basis of the above embodiment, the monitoring instrument housing 9 is also provided with a signal transmitter for signal connection to an external remote device to transmit the detection result of the detection component to the external remote device. Such a setting makes it easy for remote staff to understand the current working condition of the diesel engine so as to be able to take timely action.

[0062] In addition to the above diesel engine drive interlock monitoring system, the present invention also provides a control method for the diesel engine drive interlock monitoring system disclosed in the above embodiment, the control method comprising the following steps:

[0063] Step S1: Obtain the starting standard, and obtain the current diesel engine speed, lubricating oil pressure, fresh water pressure, supercharger lubricating oil pressure, fuel pressure and the working status of the cranking mechanism; it can be understood that the starting standard required for the diesel engine that needs to be monitored is first obtained, and the current working status and parameters of the diesel engine are obtained in real time, so as to prepare for the subsequent judgment of whether the diesel engine can be started.

[0064] Step S2: compare the current speed, oil pressure, water pressure, supercharger oil pressure, fuel pressure, and the working state of the cranking mechanism with the starting standard to determine whether the starting standard of the diesel engine is met. If so, the starting signal output by the control start button 1 can take effect; if not, the starting signal output by the control start button 1 is invalid. It can be understood that the current detection result of the diesel engine is compared with the starting standard of the diesel engine. When the cranking mechanism is in the disengaged state, and the speed, oil pressure, water pressure, supercharger oil pressure, and fuel pressure of the diesel engine are up to standard, for example, the speed is 0, the oil pressure is ≥0.2Mpa, and the water pressure is ≥0.07 Mpa, supercharger lubricating oil pressure ≥0.15Mpa, fuel pressure ≥0.1Mpa, then the current diesel engine starting standard is met, so the output circuit to control the start button 1 is turned on, and the electrical signal generated by pressing the start button 1 can be output to the start switch of the diesel engine, that is, the start signal output by the start button 1 can take effect; otherwise, the cranking mechanism is in the cranking state, and / or one or all of the above parameters are not met, then the current diesel engine starting standard is not met, so the output circuit to control the start button 1 is turned off, and the electrical signal generated by pressing the start button 1 cannot be output to the start switch of the diesel engine, that is, the start signal output by the start button 1 is invalid.

[0065] On the basis of the above embodiment, the start signal output by the control start button 1 can take effect, and also includes: when the control start signal takes effect, the start indicator 8 is allowed to output a start permission signal; the start signal output by the control start button 1 is invalid, and also includes: when the control start signal is invalid, the start indicator 8 is allowed to output a start not allowed signal; it can be understood that the on or off of the internal circuit is difficult to observe, and it is difficult to observe in time, so the start indicator 8 is allowed to output a signal to inform the operator whether it can be started. For example, when the start standard is met, the start indicator 8 is allowed to light up, otherwise, when the start standard is not met, the start indicator light remains off.

[0066] On the basis of the above embodiment, controlling the start signal output by the start button 1 to be effective also includes: obtaining a self-start speed standard, and comparing the current speed with the self-start speed standard to determine whether the self-start standard is reached; if so, controlling the start signal output by the start button 1 to be invalid; if not, obtaining the working position of the start button 1 to control the start of the diesel engine; it can be understood that when the start standard is reached, since the current speed of the diesel engine is high, it can start automatically without additional control, so after the start standard is reached, the self-start speed standard is obtained, and the current speed of the diesel engine is compared with the self-start speed standard to determine whether it is reached. To the self-start standard, when the self-start standard is reached, for example, the speed ≥ 30% of the rated speed, it can self-start, and the output circuit to control the start button 1 is disconnected. Then the electrical signal generated by pressing the start button 1 cannot be output to the start switch of the diesel engine, that is, the start signal output by the start button 1 is invalid. On the contrary, when the self-start standard is not reached, for example, the speed < 30% of the rated speed, it cannot self-start, and manual control of the diesel engine start is required to control the output circuit of the start button 1 to be turned on. Then the electrical signal generated by pressing the start button 1 can be output to the start switch of the diesel engine, that is, the start signal output by the start button 1 can take effect, effectively improving the degree of automation.

[0067] It should be noted that the relational terms such as "first" and "second" mentioned above are merely used to distinguish one entity from other entities, and do not necessarily require or imply any actual relationship or order between these entities; the "upper surface, lower surface, top, bottom" and the directional words "upper, lower, left, right" mentioned above are all defined based on the drawings in the specification.

[0068] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention.
