[0002] With the growing demand for energy, generator sets are increasingly used in various fields. In existing generator sets, the control method for starting and shutting down is usually relatively simple, usually achieved through manual operation or simple circuit control. This control method is not only complicated to operate, but also in some cases, due to improper operation or circuit failure, the generator set may not be started or shut down normally, thus affecting the stable operation of the entire system. At the same time, this control method cannot automatically adjust the operating status of the generator set according to the real-time needs of the power grid, resulting in waste or shortage of energy.
[0003] In addition, when the existing generator set is started and shut down, it is usually necessary to use equipment such as ignition coils, which are not only complex in structure, but also require frequent maintenance. Therefore, a generator set is needed that can simplify the start-up and shutdown process and reduce maintenance costs. Utility Model Content

[0027] like Figures 1 to 3 As shown, a generator set with an automatic control system provided in an embodiment of the present application includes:
[0028] The carburetor controller 2 is provided with a power interface 71 and a flywheel coil interface 21; the stop switch 221 of the carburetor controller 2 is connected by Trigger switch for the first relay 31 and the manual-automatic switching switch 222 are connected to the solenoid valve 5 of the carburetor;

[0030] An ignition circuit, wherein an ignition coil is connected to the ignition circuit;

[0032] To facilitate the description of the connection status of the switchable start lock, please refer to the following table 1:
[0033] Table 1:
[0034]
[0035] The utility model provides a generator set with an automatic control system. Compared with the prior art, the utility model can realize the start and stop of the engine in the automatic mode and the start and stop of the engine in the manual mode by setting a switchable start lock; specifically, when the switchable start lock of the utility model is switched to the first state circuit, at this time, the electromagnetic valve can only be started and shut down by opening and closing the remote control switch 6 (the remote control switch 6 is connected to a remote computer or other system, so this mode is called automatic mode), thereby realizing the start and stop of the engine, and the subsequent generation of electricity of the generator set driven by the engine;
[0036] When the switchable start lock of the utility model is switched to the second state circuit, the solenoid valve is started and shut down by opening and closing the manual automatic switching switch 222, thereby starting and shutting down the engine, and whether the generator set driven by the subsequent engine generates electricity.
[0037] When the switchable start lock of the utility model switches to the third state circuit, the ignition coil is directly turned off, so that the engine is turned off, and the purpose of shutting down the generator set is further turned off; while the first state circuit and the second state circuit actually control whether the solenoid valve is fed with oil to achieve the purpose of shutting down the engine and shutting down the generator set; therefore, the utility model can achieve the purpose of controlling the generator set in different ways by switching the circuit. (For the specific process, see the following Control Steps ).
[0038] In another embodiment of the present application, Figure 1 As shown, the flywheel coil interface 21 is connected to the detection port 14 of the AST controller 10 through the first line 141; the first line 141 is connected to one end of the flywheel coil 211, and the other end of the flywheel coil 211 is grounded. When the starter motor 82 is turned on, the flywheel coil 211 will work. At this time, the detection port 14 will sense the operation of the flywheel coil 211, that is, the engine is running, so that the AST controller 10 controls the starter motor interface 9 to stop power supply according to the internal setting circuit; thereby, the coil 51 of the second relay is de-energized, and then the trigger switch 52 of the second relay is opened, that is, the starter motor 82 is de-energized again. (This process is only implemented in the first state circuit of the switching start lock)
[0039] In another embodiment of the present application, Figure 1 As shown, the starting circuit 11 includes a battery 8, a starting motor 82, a damper controller 83, a power interface 71 and a second power interface 61; the input end of the battery 8 is grounded, and the output end of the battery 8 is respectively connected to the starting motor 82, the damper controller 83, the first power interface 72 and the second power interface 61.
[0040] In another embodiment of the present application, Figure 1 As shown, the battery 8 is also connected to an alarm indicator light 81, so that when a fault related to the battery 8 occurs, it can be known in time.
[0041] In another embodiment of the present application, Figure 2 As shown, the generator set is connected to a detection terminal 1 23 and a detection terminal 2 24 connected to the AST controller 10 .
[0042] In another embodiment of the present application, Figure 1 As shown, the AST controller is provided with two test terminals 17 and 18 connected to the external detection system. Figure 1 As shown, when the generator set is working, the detection terminal 1 23 and the detection terminal 2 24 will know that the generator set is generating electricity, so that the two test terminals 17 and 18 are turned on. At this time, by connecting the corresponding detection element or system, it can be known whether the generator set is working or not.
[0043] In another embodiment of the present application, Figure 1 As shown, a motor coil 251 is connected between the two motor charging terminals 25 of the carburetor controller 2. When the carburetor controller 2 is plugged into a power source, the motor coil 251 of the starter motor 82 can be helped to charge.
[0044] The utility model also has the following Control steps:
[0045] Step 1: The user needs to adjust the switchable start lock according to the needs, so as to switch between the first state circuit (automatic mode) and the second state circuit (manual mode).
[0046] Step 2: Operation process of the switch in each mode:
[0047] In automatic mode:
[0048] When the user selects the switchable start lock as the first state circuit (automatic mode), the first power interface 72 of the start circuit 11 is connected to the power interface 71. At this time, the power of the battery 8 is supplied to the power interface 71, and the carburetor controller 2 starts to work. However, due to Trigger switch for the first relay 31 is closed at this time, and the manual-automatic switching switch 222 is closed, and the solenoid valve 5 is turned off, so that the engine is turned off and the generator set cannot work.
[0049] In order to make the solenoid valve work; connect the remote control switch 6 to a remote computer or other system, and control the remote control switch 6 to be closed by the remote computer or other system. At this time, the power of the battery 8 will flow to The first relay Coil 32, so that Trigger switch for the first relay 31 opens, so that the solenoid valve 5 starts to supply oil; at the same time, the battery 8 also supplies electricity to the power input terminal 1, so that the starter motor interface 9 of the AST controller works, so that the coil 51 of the second relay is energized, and the trigger switch 52 of the second relay is closed, causing the starter motor 82 to ignite the engine, so that the generator set starts to work. When the generator set starts to work, the starter motor interface 9 will be powered off, so that the starter motor 82 is powered off again.
[0050] When the user needs to stop the generator from supplying power, the user only needs to control the remote control switch 6 to be disconnected through a remote computer or other system.
[0051] In manual mode:
[0052] When the user selects the second state circuit (manual mode) for the switchable start lock, the first power interface 72 of the start circuit 11 is connected to the power interface 71 , and the first power interface 72 also supplies power to the normally open switch 73 .
[0053] In order to enable the solenoid valve to work, it is necessary to manually disconnect the manual-automatic switching switch 222 so that the solenoid valve 5 can start working and supply oil; and the normally open switch 73 can energize the coil 51 of the second relay, so that the trigger switch 52 of the second relay is closed, causing the starter motor 82 to ignite the engine, so that the generator set starts working.
[0054] In order to prevent the starter motor 82 from running all the time, the second state circuit of the switchable start lock will jump to the first state circuit after working for a period of time, so that the normally open switch 73 stops supplying power. The AST controller 11 will cut off the power to the starter motor interface 9 after sensing that the engine is started, thereby cutting off the power to the starter motor 82 again.
[0055] Step 3: Shut down the engine directly:
[0056] When the mode is off:
[0057] When the user selects the third state circuit for the switchable start lock, the flameout end of the ignition circuit is connected to the ground end, so that the ignition coil cannot be powered, resulting in the engine being unable to ignite and the generator set being shut down.
