[0004] However, in this structure, due to the use of 4 separate control modules and the transmission of signals based on point-to-point topology, the following technical bottlenecks are caused: (1) High cost: Each module needs to independently customize dedicated wire harnesses, which increases the cost of wire harness procurement; (2) Low installation efficiency: The installation and connection between each module and each wire harness all rely on manual plugging and unplugging operations, which increases the installation time of a single generator; (3) Mutual interference: Signal transmission between each module is completed using wire harnesses, and it is difficult to ensure the consistency of wire layout, which will produce different degrees of interference or signal attenuation; (4) Chaotic version management: Different models of engines need to be adapted to dedicated control modules, resulting in a large number of control modules, which is not convenient for management. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated control module for generators, which solves the problems of high cost, low installation efficiency, mutual interference between conductors, and chaotic version management that arise when using multiple discrete control modules to implement different functions of a generator.

[0006] According to an embodiment of this utility model, an integrated control module for a generator includes a circuit board, on which a main control unit, a rectifier charging module, a voltage control module, a remote control module, and a speed control module are integrated, wherein:

[0007] The rectifier charging module receives the AC power output from the auxiliary winding, and after rectification, filtering, and voltage and current regulation, supplies power to the main control unit and charges the battery; at the same time, it receives the control signal transmitted by the main control unit and regulates and limits the DC power after rectification and filtering based on the received control signal.

[0008] The voltage control module adjusts the current intensity applied to the excitation winding based on the AC power received from the sampling input of the excitation power supply winding and the main winding, as well as the control signal transmitted by the main control unit.

[0009] The remote control module receives input start / stop signals, cylinder temperature data, and fuel selection signals, and transmits the received signals and data to the main control unit. Simultaneously, based on the corresponding control commands generated by the main control unit according to the signals and data, it controls the starter motor, ignition assembly, choke stepper motor, and fuel / gas solenoid valve to start and stop.

[0010] The speed control module receives the generator speed signal, idle speed function switch signal, and frequency switching signal, and transmits the received signals to the main control unit. At the same time, based on the corresponding control command generated by the main control unit according to the signal, it controls the stepper motor to operate to control the throttle opening.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By integrating the main control unit, the rectifier charging module, the voltage control module, the remote control module, and the speed control module into the same circuit board, and connecting the modules through PCB pads or board-to-board connectors, the external wiring harnesses between multiple modules can be converted into internal PCB traces. This solves the problems of high wiring harness procurement costs, low installation efficiency, and mutual interference between wires caused by the traditional generator using multiple control modules requiring independent wiring. It also reduces the amount of customized wiring harnesses used, lowers material costs, and improves installation efficiency.

[0013] By adopting the main control unit to uniformly coordinate the functions of voltage control, start-stop control, speed control, and rectification and voltage regulation power supply, the hardware interface definition and software protocol are integrated in the main control unit. Different generator models only need to adjust the software parameters of the main control unit without changing the physical interface. This solves the problem of chaotic version management caused by the non-standardized interfaces of multiple control modules used in traditional generators. It can be compatible with multiple engine models, reduces the types of integrated control modules, and facilitates the management of integrated control modules. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 2-3 As shown (where, Figure 2 Demonstrates the physical connection architecture of the functional units. Figure 3 (Refining the mechanical structure of the quick-connect interface 4), this utility model embodiment proposes an integrated control module for a generator, including a circuit board 2. The circuit board 2 integrates a main control unit 3, a rectifier charging module, a voltage control module, a remote control module, and a speed control module, wherein:

[0022] The rectifier charging module receives the AC power output from the auxiliary winding, and after rectification, filtering, and voltage and current regulation, supplies power to the main control unit 3 and charges the battery; at the same time, it receives the control signal transmitted by the main control unit 3, and performs voltage and current regulation on the rectified and filtered DC power based on the received control signal.

[0023] The rectifier charging module includes a rectifier and filter unit 51, a voltage regulator and current limiter unit 52, and a battery charging reverse connection protection unit 53. Specifically: the rectifier and filter unit 51 receives AC power from the auxiliary winding via the quick-connect interface 4 at its input terminal and performs rectification and filtering on the received AC power; the voltage regulator and current limiter unit 52 connects the rectifier and filter unit 51 and the output terminal of the main control unit 3 at its input terminal, receives the rectified and filtered DC power and the control signal transmitted by the main control unit 3, and performs voltage regulation and current limiter processing on the DC power based on the received control signal; its output terminal connects to the input terminal of the main control unit 3 to supply power to the main control unit 3; the battery charging reverse connection protection unit 53 is located between the voltage regulator and current limiter unit 52 and the battery, and is used to quickly disconnect the connection between the voltage regulator and current limiter unit 52 and the battery when the battery polarity is reversed.

[0024] Specifically, the rectifier and filter unit 51 receives the AC power output from the auxiliary winding and performs rectification and filtering on the received AC power. After rectification and filtering, the obtained DC power is transmitted to the voltage regulation and current limiting unit 52. Then, the voltage regulation and current limiting unit 52 regulates the voltage of the transmitted DC power according to the control signal (such as PWM control signal) transmitted by the main control unit 3, thereby achieving voltage regulation and current limiting of the DC power. After voltage regulation and current limiting, the DC power is transmitted to the battery through the battery charging reverse connection protection unit 53 to charge the battery. At the same time, the DC power is transmitted to the main control unit 3 to power the main control unit 3. By setting the battery charging reverse connection protection unit 53 between the voltage regulation and current limiting unit 52 and the battery, the battery charging reverse connection protection unit 53 can quickly disconnect the connection between the voltage regulation and current limiting unit 52 and the battery when the battery polarity is reversed, so as to avoid damage to the voltage regulation and current limiting unit 52 or causing a safety accident.

[0025] The voltage control module adjusts the current intensity applied to the excitation winding based on the received AC power input from the excitation power supply winding and the main winding, as well as the control signal transmitted by the main control unit 3.

[0026] The voltage control module includes a voltage regulation control unit 61. The input terminal of the voltage regulation control unit 61 is connected to the output terminal of the main control unit 3, and receives the control signals transmitted by the main control unit 3. At the same time, the input terminal of the voltage regulation control unit 61 also receives AC power sampled from the excitation power supply winding and the main winding through the quick-connect interface 4. The output terminal of the voltage regulation control unit 61 adjusts the current intensity applied to the excitation winding through the quick-connect interface 4.

[0027] Specifically, the voltage regulation control unit 61 receives AC power (including the actual voltage value) sampled from the excitation power supply winding and the main winding, and simultaneously receives control signals (such as target voltage value or adjustment command) issued by the main control unit 3. Then, the voltage regulation control unit 61 compares the actual voltage value with the target voltage value, obtains the comparison result, and then adjusts the current intensity applied to the excitation winding through PWM according to the comparison result (for example, when the voltage is lower than the reference, the magnetic field is strengthened by increasing the current of the excitation winding to increase the output voltage; conversely, the current of the excitation winding is reduced to weaken the magnetic field and achieve voltage reduction).

[0028] The remote control module receives input start / stop signals, cylinder temperature data, and fuel selection signals, and transmits the received signals and data to the main control unit 3. Simultaneously, based on the corresponding control commands generated by the main control unit 3 according to the signals and data, it controls the start / stop of the starter motor, ignition assembly, choke stepper motor, and fuel / gas solenoid valve. The remote control module includes a start / stop control unit 71 and a power management unit, wherein:

[0029] The start-stop control unit 71 receives start-stop signals, cylinder temperature data, and fuel selection signals at its input terminal via the quick-connect interface 4; simultaneously, its input terminal is also connected to the output terminal of the main control unit 3 to receive control commands transmitted by the main control unit 3; its output terminal is connected to the input terminal of the main control unit 3 to transmit the received signals and data to the main control unit 3.

[0030] Specifically, the start-stop control unit 71 receives start-stop signals (including three types: start-stop signals input via buttons on the local panel assembly, start-stop signals input via the automatic backup power switch, and start-stop signals input via remote control buttons), cylinder temperature data transmitted by the cylinder head temperature sensor, and fuel selection signals input via the fuel selection switch on the panel assembly. It then transmits these received signals to the main control unit 3, enabling the main control unit 3 to generate corresponding control commands based on the received signals to control the power management unit. Simultaneously, the main control unit 3 also feeds back the generated control commands to the start-stop control unit 71, achieving collaborative operation between the main control unit 3 and the start-stop control unit 71 to ensure the stable operation of the integrated control module.

[0031] The power management unit receives control commands from the main control unit 3 and controls the starter motor, igniter assembly, choke stepper motor and fuel / gas solenoid valve to start and stop based on the received control commands.

[0032] The power management unit includes a start control subunit 721, an engine shutdown and power control subunit 722, a choke control subunit 723, a fuel control subunit 724, and a gas control subunit 725, wherein:

[0033] The start-up control subunit 721 has its input terminal connected to the output terminal of the main control unit 3, receiving start-up commands transmitted by the main control unit 3; its output terminal controls the start and stop of the starter motor through the quick-connect interface 4. The ignition and power control subunit has its input terminal connected to the output terminal of the main control unit 3, receiving ignition commands transmitted by the main control unit 3; its output terminal controls the start and stop of the igniter assembly through the quick-connect interface 4. The choke control subunit 723 has its input terminal connected to the output terminal of the main control unit 3, receiving start-up commands transmitted by the main control unit 3. The main control unit 3 transmits control commands; its output terminal controls the start and stop of the choke stepper motor through the quick-connect interface 4; the fuel control subunit 724, whose input terminal is connected to the output terminal of the main control unit 3, receives control commands transmitted by the main control unit 3; its output terminal controls the opening and closing of the fuel solenoid valve through the quick-connect interface 4; the gas control subunit 725, whose input terminal is connected to the output terminal of the main control unit 3, receives control commands transmitted by the main control unit 3; its output terminal controls the opening and closing of the gas solenoid valve through the quick-connect interface 4.

[0034] Specifically, after the main control unit 3 generates corresponding control commands (including start command, ignition command, choke control command, and fuel selection control command) based on the received start / stop signal, cylinder temperature data, and fuel selection signal, the main control unit 3 sends the start command to the start control subunit 721, enabling the start control subunit 721 to control the starter motor to start or stop according to the received start command; the main control unit 3 sends the ignition command to the ignition and power control subunit, enabling the ignition and power control subunit to control the ignition assembly to start or stop according to the received ignition command; the main control unit 3 sends the choke control command to the choke control subunit 723, enabling the choke control subunit 723 to control the starter motor to start or stop according to the received ignition command; and the main control unit 3 sends the choke control command to the choke control subunit 723, enabling the choke control subunit 723 to control the starter motor to start or stop according to the received ignition command. 3. The choke stepper motor can be started and stopped according to the received choke control command (the control logic of the choke control unit is: during cold start, it receives the closing command from the main control unit 3, drives the choke stepper motor to close the choke, and as the engine temperature rises, it drives the choke stepper motor to gradually open the choke until the choke reaches the fully open state and remains fully open under normal operating conditions); the main control unit 3 will send the fuel selection control command (fuel / gas) to the corresponding fuel control subunit 724 or gas control subunit 725, so that the fuel control subunit 724 or gas control subunit 725 can control the opening and closing of the fuel solenoid valve or gas solenoid valve according to the received fuel / gas control command.

[0035] The speed control module receives the generator speed signal, idle speed function switch signal, and frequency switching signal, and transmits the received signals to the main control unit 3; at the same time, based on the corresponding control command generated by the main control unit 3 according to the signal, it drives the stepper motor to operate to control the throttle opening.

[0036] The speed control module includes a speed acquisition and control unit 81 and a throttle control unit 82. The speed acquisition and control unit 81 receives generator speed signals, idle speed function switch signals, and frequency switching signals at its input end via the quick-connect interface 4; its output end is connected to the input end of the main control unit 3, transmitting the received signals to the main control unit 3. The throttle control unit 82 receives corresponding control commands generated by the main control unit 3 based on the signals at its input end; its output end drives a stepper motor to control the throttle opening via the quick-connect interface 4.

[0037] Specifically, the speed acquisition and control unit 81 receives the generator's speed signal (obtained indirectly by detecting the pulse frequency of the igniter or trigger to obtain the actual operating speed signal of the generator), the idle speed function switch's on / off signal, and the frequency switching signal of the frequency conversion switch 108. The speed acquisition and control unit 81 then processes each received signal (the idle speed function switch's on / off signal and the frequency switching signal of the frequency conversion switch 108 are converted into the corresponding target speed value using the idle speed-frequency-corresponding tachometer built into the speed acquisition and control unit 81), obtaining the generator's actual speed value and target speed value. This data is then sent to the main control unit 3, which compares the actual speed value and the target speed value, generates a corresponding control command, and sends this control command to the throttle control unit 82. The throttle control unit 82 then drives the stepper motor (throttle stepper motor) to control the throttle opening, thereby adjusting the generator speed.

[0038] Furthermore, the circuit board 2 is provided with several quick-connect interfaces 4. These quick-connect interfaces 4 are used for input and output connections of the rectifier charging module, the voltage control module, the remote control module, and the speed control module, so as to realize plug-and-play connection between the integrated control module and the generator body. Specifically, the quick-connect interfaces 4 integrate power terminals, signal terminals, and data communication terminals (such as...). Figure 3 As shown in CN1-CN8, the quick-connect interface 4 must comply with the IEC 61984 standard, and the power terminals integrated in the quick-connect interface 4 must meet the anti-misinsertion design (contact spacing ≥ 3mm).

[0039] Furthermore, the circuit board 2 also integrates a data processing module, which includes a voltage processing unit 91 and a current processing unit 92. The voltage processing unit 91 receives the generator main winding output voltage at its input terminal via the quick-connect interface 4; its output terminal is connected to the input terminal of the main control unit 3, inputting the processed voltage data into the main control unit 3. The current processing unit 92 receives the transformer-generator load current at its input terminal via the quick-connect interface 4; its output terminal is connected to the input terminal of the main control unit 3, inputting the processed current data into the main control unit 3.

[0040] Specifically, the voltage processing unit 91 receives the output voltage of the generator main winding and processes the received output voltage. After processing, the processed voltage data is transmitted to the main control unit 3. The current processing unit 92 receives the transformer-generator load current and processes the received load current. After processing, the processed current data is transmitted to the main control unit 3. When the main control unit 3 receives the processed voltage and current data, it compares the received voltage and current data with preset target voltage and target current parameters and generates a corresponding control signal (such as a PWM control signal). Based on the control signal, it regulates and limits the DC power transmitted from the voltage regulation and current limiting unit 52, and compares the actual voltage value with the target voltage value in the voltage regulation and control unit 61 based on the control signal.

[0041] Furthermore, the circuit board 2 also integrates an oil signal detection unit 101, a CO online detection unit 102, a branch power control unit 103, a running and fault warning unit 104, an oil warning unit 105, a speed signal conversion unit 106, and an electrical parameter signal conversion unit 107, wherein:

[0042] The oil signal detection unit 101 receives the oil sensor's switch signal at its input end via the quick-connect interface 4, and its output end is connected to the input end of the main control unit 3; the CO online detection unit 102 receives the CO module's anti-tampering and alarm signals at its input end via the quick-connect interface 4, and its output end is connected to the input end of the main control unit 3; the branch power control unit 103 has its input end connected to the output end of the main control unit 3, and its output end outputs the power output signals of the instrument panel and CO module to the instrument panel and CO module via the quick-connect interface 4; the operation and fault warning unit 104 has its input end connected to the main control unit 3. The output terminal of the main control unit 3 outputs running and fault indication signals to the running indicator and fault indicator through the quick-connect interface 4; the oil warning unit 105 has its input terminal connected to the output terminal of the main control unit 3, and its output terminal outputs a low oil warning signal to the oil warning light through the quick-connect interface 4; the speed signal conversion unit 106 has its input terminal connected to the output terminal of the main control unit 3, and its output terminal outputs a speed signal to the ATS through the quick-connect interface 4; the electrical parameter signal conversion unit 107 has its input terminal connected to the output terminal of the main control unit 3, and its output terminal outputs an electrical parameter signal to the instrument through the quick-connect interface 4.

[0043] Specifically, after receiving the switch signal from the oil sensor and the anti-tampering and alarm signals from the CO module, the oil signal detection unit 101 and the CO online detection unit 102 transmit the received signals to the main control unit 3. The main control unit 3 then sends the received signals to the branch power control unit 103, the operation and fault warning unit 104, and the oil warning unit 105. The main control unit 3 can send the speed signal to the speed signal conversion unit 106 and the electrical parameter signal to the electrical parameter signal conversion unit 107, so that the branch power control unit 103 can output the power output signals of the instrument and the CO module to the instrument and the CO module. The operation and fault warning unit 104 can output operation and fault indication signals to the operation indicator and fault indicator; the oil warning unit 105 can output a low oil warning signal to the oil warning light; the speed signal conversion unit 106 can output a speed signal to the ATS (Automatic Switch for Backup Power) to control the switching of the ATS according to the speed signal; the electrical parameter signal conversion unit 107 can output electrical parameter signals (including speed, frequency, temperature, output voltage, load current, etc.) to the instrument for display on the instrument, so that the main control unit 3 can centrally process the received signals and data and uniformly regulate them to avoid inconsistent control steps of the start-up or shutdown of the generator components.

[0044] like Figure 4 and Figure 5 As shown, based on the above embodiments, according to another embodiment of the present invention, the circuit board 2 is placed inside the metal protective housing 1. Specifically, the circuit board 2 is placed inside the metal protective housing 1 so that the metal protective housing 1 can effectively isolate external electromagnetic interference (such as radio signals, lightning, etc.) and at the same time prevent the electromagnetic radiation generated by the circuit board 2 from affecting other electronic devices, thereby improving anti-interference capability.

[0045] Furthermore, the power ground of the circuit board 2 is located on the bottom layer of the circuit board 2 to be connected to the metal protective housing 1; irregular heat dissipation fins 11 are provided on the outside of the metal protective housing 1. Specifically, since each module and unit integrated on the circuit board 2 needs to be grounded, a large amount of heat will accumulate at the grounding point. By setting a grounding layer on the bottom layer of the circuit board 2, the grounding area can be increased and the heat dissipation effect can be improved. By connecting the power ground of the circuit board 2 to the metal protective housing 1 and providing irregular heat dissipation fins 11 on the outside of the metal protective housing 1, the heat on the circuit board 2 can be dissipated from the metal protective housing 1, further improving the heat dissipation effect.

[0046] The detailed working process of this embodiment is as follows:

[0047] The start / stop signal, cylinder temperature data transmitted by the cylinder head temperature sensor, and fuel selection signal input from the fuel selection switch on the panel assembly are input through the quick-connect interface 4 to the start / stop control unit 71. This allows the start / stop control unit 71 to transmit the received signals to the main control unit 3. The main control unit 3 can then generate corresponding control commands based on the received signals and send these commands to the control subunit, the flameout and power control subunit 722, the choke control subunit 723, the fuel control subunit 724, and the gas control subunit 725. Consequently, the control subunit, the flameout and power control subunit 722, the choke control subunit 723, the fuel control subunit 724, and the gas control subunit 725 can control the starter motor, ignition assembly, and choke stepper motor, as well as the opening and closing of the fuel solenoid valve or gas solenoid valve, based on the received control commands, thereby enabling the generator to start.

[0048] After the generator starts, the generator speed signal, the idle speed function switch switch signal, and the frequency switching signal of the frequency conversion switch 108 are input to the speed acquisition and control unit 81 through the quick-connect interface 4. This allows the speed acquisition and control unit 81 to transmit the received signals to the main control unit 3, which in turn generates corresponding control commands based on the received signals and sends these commands to the throttle control unit 82. Consequently, the throttle control unit 82 drives the stepper motor to control the throttle opening, thereby regulating the generator speed.

[0049] The generator main winding output voltage and transformer-generator load current are input through the quick-connect interface 4 to the voltage processing unit 91 and the current processing unit 92. After processing the received voltage and current data, the voltage processing unit 91 and the current processing unit 92 transmit the processed voltage and current data to the main control unit 3. The main control unit 3 can then generate corresponding control commands or control signals based on the received voltage and current data, and send these commands or signals to the voltage stabilization and current limiting unit 52 and the voltage regulation and control unit 61. The voltage stabilization and current limiting unit 52 can then regulate and limit the input DC current according to the control commands or control signals, while the voltage regulation and control unit 61 can compare the actual voltage value with the target voltage value according to the control commands or control signals, obtain the comparison result, and then adjust the current intensity applied to the excitation winding based on the comparison result.

[0050] The rectifier and filter unit 51 receives the AC power output from the auxiliary winding through the quick-connect interface 4 and performs rectification and filtering on the received AC power. After rectification and filtering, the obtained DC power is transmitted to the voltage regulation and current limiting unit 52. Then, the voltage regulation and current limiting unit 52 regulates the voltage of the transmitted DC power according to the control signal (such as PWM control signal) transmitted by the main control unit 3, thereby achieving voltage regulation and current limiting of the DC power. After voltage regulation and current limiting, the DC power is transmitted to the battery through the battery charging reverse connection protection unit 53 to charge the battery. At the same time, the DC power is transmitted to the main control unit 3 to supply power to the main control unit 3.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
