Description

Technical Field

[0001] This invention relates to a generator, and more specifically to a generator and control method based on APP control. Background Technology

[0002] Generators, as power devices that convert other forms of energy into electrical energy, are used in various industries. With the widespread application of intelligent technology, generators can now be remotely controlled to start and stop, facilitating their better use.

[0003] For example, Chinese patent document CN114087084B discloses an APP-based start-stop control method for fuel generators. This method integrates an APP control module onto the fuel generator and enables remote data interaction between the APP control module and an APP mobile control terminal via a wireless network. This allows the APP mobile control terminal to remotely and wirelessly send generator control commands to the APP control module on the generator. The APP control module then identifies and judges the generator control commands and monitors the generator's current operating status in real time. Based on the judged command type and the detected generator operating status, it controls the start and stop of the fuel generator. Compared to the existing ATS control box control method, this method more conveniently achieves remote start-stop control of fuel generators, and eliminates the need for a bulky ATS control box at the factory, effectively saving material and transportation costs. While this prior art solves the problem of large ATS size, it requires multiple judgments, making the process more complex and reducing control efficiency. Summary of the Invention

[0004] To address the technical problem of low control efficiency in the prior art, this invention provides a generator based on APP control, comprising an APP control module, a power generation module, a power module, and a control module. The APP control module is communicatively connected to a user terminal, the control module controls the start and stop of the power module, and the power generation module is driven by the power module. After receiving the trigger signal from the user terminal, the APP control module is also used to detect the inverter signal of the control module or the voltage waveform of the generator module, and determine the current status of the generator based on the detection results. The control module then sends a shutdown command or a start command based on the current status of the generator.

[0005] In this solution, after receiving a trigger signal, the APP control module determines the current state of the generator by detecting the inverter signal of the control module or the voltage waveform of the generator module. Then, it controls the generator to stop or start based on the current state. Compared with existing technologies, the operation process is simpler and the control efficiency is improved.

[0006] Preferably, the APP control module stores preset inverter signals or preset voltage waveforms. When determining the current state of the generator, if the detected inverter signal or voltage waveform matches the preset inverter signal or voltage waveform, the generator is determined to be in a started state, and the control module sends a stop command. If no inverter signal or voltage waveform is detected, the control module sends a start command. This solution can effectively determine the current state of the generator and is simple to operate.

[0007] Preferably, the power module starts upon receiving the start command. The APP control module or control module determines whether the generator has started successfully. If the generator fails to start after multiple attempts, the generator startup is stopped. In this solution, the generator startup is stopped after multiple unsuccessful attempts to start, in order to avoid damage to the generator caused by repeated forced starts.

[0008] Preferably, after the power module starts, the APP control module or control module detects the inverter signal of the control module or the voltage waveform of the generator module. When the detected inverter signal or voltage waveform matches the preset inverter signal or preset voltage waveform, the generator is determined to have started successfully; otherwise, the start-up is determined to have failed. This solution can improve the accuracy of the determination.

[0009] Preferably, the control module has preset start counts and start durations. When a generator start failure is determined, the control module controls the power module to start again and performs another check. Only if the power module fails to start successfully after the preset number of starts within the start duration is the start failure determined. This solution can further improve the accuracy of the determination.

[0010] Preferably, the system also includes an alarm module. When the detected inverter signal or voltage waveform does not match the preset inverter signal or voltage waveform, the control module sends an alarm signal. This solution can provide an alarm for faults, reminding the user to handle the faults promptly.

[0011] Preferably, the APP control module is also communicatively connected to a fuel switching device with a fuel switch. When the APP control module receives a start command, it controls the fuel switching device to open the fuel switch; when it receives a stop command, it controls the fuel switching device to close the fuel switch. This solution can switch the fuel delivery status in a timely manner and is simple to operate.

[0012] Secondly, the present invention also provides a control method for a generator based on APP control, using the generator as described in any one of claims 1-7, comprising the following steps: S1. Receive the trigger signal and detect the inverter signal or voltage waveform after receiving the trigger signal; S2. Determine the current operating status of the generator based on the detection results; S3. Send a shutdown command or a start command based on the current operating status of the generator.

[0013] The present invention has the following beneficial effects: 1. This invention determines the current state of the generator by detecting the inverter signal of the control module or the voltage waveform of the generator module, and then controls the generator to stop or start based on the current state. Compared with the prior art, the operation process is simpler and the control efficiency can be improved.

[0014] 2. This invention can improve the accuracy of determining the current state of the generator, thereby ensuring accurate control of the generator. Attached Figure Description

[0015] Figure 1 This is a flowchart illustrating an embodiment of the generator and control method based on APP control according to the present invention. Detailed Implementation

[0016] The following detailed description illustrates the specific implementation method: 1. Definition Inverter signal: refers to the signal emitted by the control module.

[0017] 2. The basic implementation is as follows: The generator based on APP control includes an APP control module, a generator module, a power module, a control module and an alarm module. The APP control module is connected to the user terminal for communication. The control module controls the start and stop of the power module. The generator module is connected to the power module for driving. After receiving the trigger signal from the user terminal, the APP control module is also used to detect the inverter signal of the control module or the voltage waveform of the generator module, and determine the current status of the generator based on the detection results. The control module then sends a shutdown command or a start command based on the current status of the generator.

[0018] Specifically, the APP control module stores preset inverter signals or preset voltage waveforms. When determining the current state of the generator, if the detected inverter signal or voltage waveform matches the preset inverter signal or voltage waveform, the generator is determined to be in the start state, and the control module sends a stop command. If no inverter signal or voltage waveform is detected, the control module sends a start command.

[0019] Upon receiving a start command, the power module starts. The APP control module or the control module determines whether the generator has started successfully. If the generator fails to start after multiple attempts, the generator startup is stopped. Specifically, the control module presets the number of starts and the start duration. After the power module starts, the APP control module or the control module detects the inverter signal of the control module or the voltage waveform of the generator module. When the detected inverter signal or voltage waveform matches the preset inverter signal or voltage waveform, the generator is considered to have started successfully. If a start fails once, the control module controls the power module to start again and performs a check. If the power module fails to start after the preset number of starts within the start duration, the start is considered a failure. In this embodiment, the control module performs the check.

[0020] When the detected inverter signal or voltage waveform does not match the preset inverter signal or preset voltage waveform, the control module sends an alarm signal.

[0021] The APP control module is also connected to a fuel switching device with a fuel switch. When the APP control module receives a start command, it controls the fuel switching device to open the fuel switch. When it receives a stop command, it controls the fuel switching device to close the fuel switch.

[0022] The specific implementation process is as follows: The APP control module communicates with the user terminal. The user sends a trigger signal through the user terminal. After receiving the trigger signal, the APP control module starts to detect the inverter signal or voltage waveform and compares the detected inverter signal or voltage waveform with a preset inverter signal or voltage waveform. In this embodiment, the inverter signal is used as an example.

[0023] like Figure 1 As shown, after receiving a trigger signal, the APP control module detects the inverter signal. If no inverter signal is detected, it determines that the generator is currently in a stopped state, and the control module sends a start signal to start the generator. If an inverter signal is detected, it determines that the generator is in a running state, and the control module sends a stop signal to stop the generator.

[0024] After the control module sends a start signal, it detects the inverter signal. If the inverter signal is detected, the generator is considered to have started successfully. If the inverter signal is not detected, it is started again. If the power module fails to start successfully after the preset number of restarts within the start time, the start is considered to have failed.

[0025] When an inverter signal is detected, it is matched with a preset inverter signal. If the inverter signal does not match the preset inverter signal, the alarm module sends an alarm signal. Specifically, the alarm signal includes, but is not limited to, abnormalities such as startup, operation, and shutdown. Among them, operational abnormalities include overvoltage, overload, short circuit, overspeed, and low speed.
