Description

Technical Field

[0001] The invention relates to the technical field of generator control, and in particular to a general-purpose power supply module with a monitoring function and a power supply method. Background Art

[0002] Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are all based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of their construction is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic power and achieve the purpose of energy conversion.

[0003] In addition to using an inverter circuit to convert chemical energy into mechanical energy through combustion and then into 110VAC and 220VAC AC power, the generator is usually equipped with a module that can convert low-voltage DC, called a DC voltage regulator. This module converts the AC power provided by the generator charging coil into a DC voltage source through voltage regulation circuits such as step-down and voltage stabilization, and provides DC output to modules such as the starting battery outside the generator, the solenoid valve that supplies fuel to the carburetor, the generator instrument panel, and other generator peripherals.

[0004] Normally, the generator DC voltage regulator is constructed with analog circuit devices such as thyristors, voltage-stabilizing diodes, and triodes. Although it has the advantages of simple circuit structure and low cost, its output power is small, its function is single, and its load capacity is not high. Usually, its output power is within 100W, and the output DC voltage contains industrial frequency AC components. It is only used as a charging module with a single function. When the generator power supply module is started, the output current is also directly output to all electrical devices with useful power demand, and the operating load is large.

[0041] During implementation, when the engine or generator is started, the speed data is transmitted to the control unit through the speed sensor, and then the power supply sequence of multiple paths at the output end of the generator is adjusted and controlled through the control circuit of the control unit;

[0042] Specifically, the electric energy generated by the generator can be directly transmitted to the oil supply solenoid valve for power supply through the generator output circuit 1 and the voltage regulation conversion circuit 2; the oil supply solenoid valve is used to control the amount of oil entering the oil pump, and the oil supply solenoid valve is connected to the first output end of the voltage regulation conversion unit through the first drive circuit 3.

[0043] In addition, the electric energy of the oil supply solenoid valve is also directly powered by the battery, and the battery supplies power to the oil supply solenoid valve through the second drive circuit 4 of the oil supply solenoid valve.

[0044] During implementation, the control unit specifically controls the first drive circuit and the second drive circuit through the first output terminal PD3 and the second output terminal P4. Specifically, the first output terminal PD3 is connected to the G pole of the MOS tube Q9, and the second output terminal PD4 is connected to the positive pole of the light-emitting diode of the photocoupler; during implementation, the paths of the first drive circuit and the second drive circuit are as follows:

[0045] The driving principle of the first driving circuit 3 is: when the driving electrical signal of the control unit passes through the first output terminal PD3, it directly acts on the MOS transistor Q9 and the MOS transistor Q8 and turns them on, so that the electrical energy output by the rectifier output unit is directly output to the fuel supply battery;

[0046] The driving principle of the second driving circuit 4 is: the control signal of the control unit enters the second output terminal PD4, so that the photoelectric coupler U18 is turned on, and then the electric energy of the battery can flow into the first driving circuit to continuously drive the fuel supply solenoid valve.

[0047] Specifically, the speed sensor is connected to the control circuit 6 of the control unit through the speed acquisition circuit 5, the output end of the speed sensor is connected to the positive electrode of the diode D21, the first branch of the negative electrode of the diode D21 is connected to a resistor R85, the other end of the resistor R85 is connected to the positive electrode of the light-emitting diode of the photoelectric coupler U8, the negative electrode of the light-emitting diode of the photoelectric coupler U8 is connected to a resistor R83, the other end of the resistor R83 is connected to the positive electrode of the diode D26, and the negative electrode of the diode D26 is grounded; the second branch of the negative electrode of the diode D21 is connected to a capacitor C40, and the other end of the capacitor C40 is connected between the photoelectric coupler U8 and the resistor R83; one end of the transistor of the photoelectric coupler U8 is connected to the power supply, and the other end of the transistor of the photoelectric coupler U8 is connected to the input end PC4 of the control unit through a filter circuit;

[0054] S31, judging whether the speed of the generator rotor coil is greater than 2000 revolutions per minute or whether the voltage supplied by the generator to the voltage regulation conversion circuit is greater than 15V. If the speed and voltage are both greater than the set parameters, the engine is started successfully, otherwise it needs to be restarted;

[0055] S32. When the engine is successfully started, the power supply collection unit and other power supply components supply power to the battery; specifically, the speed sensor, the oil alarm, the carbon monoxide alarm and the battery are charged;

[0056] S33. The control unit determines whether the generator or the engine is abnormal based on the data collected by the collection unit. If the speed data, oil volume, and data collected by the carbon monoxide alarm are normal, the power supply will continue to be supplied if normal; otherwise, the power supply battery valve and loads not related to the power will be cut off first, and then the engine and generator will be shut down with a delay of 1 second. This will allow the remaining fuel in the engine to burn out, thereby avoiding abnormal noise (explosion) when the engine and generator are shut down.
