[0003] For example, the engine stop control flameout line needs to be controlled by the inverter, the power itself control module, the operation panel and even the carbon monoxide protection module, forming the phenomenon that multiple module components control one execution component; at the same time, the boss trigger signal needs to be input to the inverter, the engine control module and even the panel instrument, forming the phenomenon that one signal is received by multiple modules. Such reuse and overlap cause serious interference between multiple components of the system, resulting in functional failure of the product or damage to the components. At the same time, the system thread is very complex, resulting in the formation of a spider web between multiple threads. Once the system fails, it is difficult to check and troubleshoot due to the complex thread. In the case of necessity, the entire thread and operation panel must be replaced.

[0029] In order to make the purpose, technical scheme and advantages of the present disclosure more clear, the following will be further described in detail in combination with specific embodiments and with reference to the drawings.

[0030] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of the present application should be understood as the usual meaning understood by those skilled in the art to which the present disclosure belongs. The "first", "second" and similar words used in one or more embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Include" or "contain" and similar words mean that the elements or objects before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connected" or "connected" and similar words are not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] As shown in the drawingsFigures 1-9 The embodiment provides a generator control circuit with a relay module, which comprises:

[0032] The generator control circuit comprises a generator power module, a generator control module and an engine relay module, and the generator power module and the generator control module are connected in communication through the engine relay module.

[0033] The generator power module comprises a magneto inverter set and an engine, and the generator control module comprises a generator control panel.

[0034] The engine relay module comprises a relay main control circuit, an AC interface and a power circuit, and the AC interface and the power circuit are electrically connected with the relay main control circuit.

[0035] The magneto inverter is connected in communication with the engine and the engine relay module through a LIN bus, the engine is connected in bidirectional communication with the engine relay module, and the engine relay module is connected with the generator control panel through the LIN bus.

[0036] The engine relay module is further connected with an expansion module through the LIN bus. The expansion module comprises an engine power control circuit and an inverter control circuit. The engine power control circuit comprises an oil-gas switching circuit, an external flameout detection circuit and an engine oil detection circuit, and the inverter control circuit comprises an inverter flameout circuit, an idling control circuit and a carbon monoxide detection circuit. The engine relay module is located between the generator power module and the generator control module and is integrated on a PCB board, and the PCB board is arranged on the back of the generator control panel.

[0037] In the embodiment, the input signal and the output control are processed by the relay module CPM, and then single-link control is performed, so that the phenomenon of superposition and multiplexing of threads no longer occurs. After the components are controlled by the bus, the number of threads is greatly reduced, all signals are communicated by the bus, and digital processing is performed. The complexity of threads is greatly reduced, the difficulty of troubleshooting and maintenance is reduced, the components can be replaced individually and conveniently, and feasibility is provided. In addition, the entire system adopts the relay module CPM, the interference between signals is greatly reduced, and the reliability of the system is improved.

[0038] In existing products, threads must increase some electronic components such as diodes because of signal superposition and multiplexing, and PTC self-recovery fuses are additionally increased to protect the module from being damaged. These electronic components are suitable for PCB processing and production, but now they are connected in series in the wire, so that thread processing is very complex and quality accidents are prone to occur.

[0039] At the same time, electronic components are applied to the thread, which causes great quality problems in the product service life. Once the fragile electronic component pin is damaged, the entire thread will be damaged, and the machine will also malfunction. Moreover, such machine failure is difficult to troubleshoot, the thread is very messy, and it is difficult for people to find the fault wire. Moreover, the hidden nature of the series processing electronic components is high, and it is difficult to find.

[0040] After improvement, all threads are not stacked and reused, forming a single thread condition, which is convenient for factory mechanized production management, and thread modularization standards also appear, which can realize large-scale low-cost production with less manpower! Moreover, the modularized thread can be used on multiple models. That is, the universality of the thread is realized.

[0041] Since the bus control is adopted and the thread is modularized, when the host factory produces and installs the machine, it becomes very simple to install the fixed module and plug in the bus, which greatly reduces the operation difficulty of workers and improves the production efficiency.

[0042] The appearance of the relay module CPM makes the generator in the production and assembly process can directly assemble the engine control module and inverter module together with the engine. Moreover, the man-machine operation panel and the thread can be assembled separately. That is, the engine and other mechanical parts can be produced and assembled independently, and the man-machine operation panel can be assembled and tested separately. This is particularly important in the silent generator set! Because the silent generator is a fully covered machine, the front panel is a large piece, and it has many long threads, which is very noisy to produce and assemble. The appearance of the CPM module completely realizes the production isolation of the two components. That is, the silent generator can be produced and assembled without the panel thread. In addition, the LIN bus interface is simple, which reduces the complexity of the system. At the same time, LIN is one of the automobile buses, and has very high reliability.

[0043] One or more embodiments in the application provide a generator comprising the generator control circuit with a relay module described in any one of the above.

[0044] Although the preferred embodiments of the present application have been described, those skilled in the art can make further changes and modifications to the embodiments once they know the basic inventive concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0045] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
