[0051] Figure 1 This is a block diagram illustrating the composition of an automatic maintenance device for a generator car, provided in an embodiment of the present invention.

[0052] Figure 2 This is a hardware design block diagram of an automatic maintenance device for a generator car provided in an embodiment of the present invention. Detailed Implementation

[0053] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0054] Please see Figure 1 This invention provides an automatic maintenance device for a generator car, comprising:

[0055] Sensor module, data acquisition module, timing module, control module, execution module, and human-computer interaction module;

[0056] The sensor module is used to collect the external physical parameters of the generator vehicle. External physical parameters refer to physical quantities related to the surrounding environment and the generator vehicle's own state during operation, such as temperature, humidity, vibration frequency, noise level (decibels), rotational speed, and pressure. A sensor is a device that converts physical parameters into electrical signals or other transmittable signals, including temperature sensors (such as thermocouples and thermistors), humidity sensors (such as capacitive humidity sensors), and vibration sensors (such as piezoelectric vibration sensors).

[0057] The data acquisition module receives external physical parameters and performs preprocessing. Preprocessing refers to the initial processing of raw data to improve data quality and applicability, including operations such as filtering (removing noise interference), amplification (enhancing weak signals), analog-to-digital conversion (converting analog signals into digital signals), and data calibration (correcting sensor errors). The data acquisition card is the hardware device that implements the data acquisition function, receiving and processing analog signals output from sensors.

[0058] The timing module is used to collect time data for each operating mode of the generator car. Operating mode refers to the generator car's operating state under different working conditions, such as start-up mode, rated operation mode, idling mode, and shutdown mode. Time data includes the start time, duration, and end time of each operating mode. The timing module can accurately record time information during the generator car's operation using timing elements such as a real-time clock. When the generator car switches to a different operating mode, the module can detect the mode switch and automatically record the start time of that mode; during the mode operation, it continuously times the duration of operation; and when the mode switch ends, it records the end time. This time data reflects the generator car's operating time in each mode, providing a time-based basis for determining maintenance rules.

[0059] The control module generates a set of maintenance control commands based on preprocessed external physical parameters and time data, according to preset rules. These preset rules regulate the operation and maintenance of the generator car to meet its maintenance needs. The module also generates corresponding maintenance result information based on feedback from the execution module. Preset rules are a series of logic and conditions based on the generator car's maintenance needs, typically stored as algorithms, programs, or databases. Examples include rules such as "if the engine operating temperature exceeds 80°C for 30 consecutive minutes and the operating mode remains normal for 2 hours, a cooling maintenance command will be issued." Maintenance control commands are operation commands issued by the control module to the execution module, such as starting the cooling system, prompting filter replacement, or lubricating components. Feedback refers to the information returned by the execution module to the control module regarding the operation results. The control module receives preprocessed external physical parameters from the data acquisition module and time data from the timing module, compares this data with the preset rules, and performs logical operations. When the data meets the trigger conditions in the preset rules, the control module generates the corresponding maintenance control command according to the rules and sends it to the execution module. Simultaneously, the control module receives operation result feedback information from the execution module, judges the command execution status based on the feedback, and generates corresponding maintenance result information.

[0060] The execution module performs corresponding operations on the generator car according to a set of maintenance control commands and feeds back the operation results to the control module. The execution operation refers to the specific maintenance actions performed on the generator car based on the maintenance control commands, such as controlling valve opening and closing, starting the motor, adjusting equipment parameters, and issuing alarm prompts. The actuator is the device that performs the operation, including solenoid valves, motors, relays, and alarms (such as audible and visual alarms). The feedback mechanism refers to the process by which the execution module returns information such as whether the operation was successful and the post-operation equipment status to the control module.

[0061] The human-machine interface (HMI) module displays maintenance results from the control module and receives external maintenance commands, enabling the control module to generate corresponding maintenance control commands. Maintenance results include the execution status of maintenance commands, current equipment status, fault indicators, and maintenance suggestions. External maintenance commands are manual control commands input by operators through the HMI, such as forcibly starting the maintenance program or modifying maintenance parameters. The HMI includes a display screen (e.g., a monitor or touchscreen), buttons, indicator lights, and a buzzer.

[0062] This embodiment provides an automatic maintenance device for a generator car. The device is based on a sensor module that collects external physical parameters of the generator car. A data acquisition module preprocesses the raw parameters to obtain valid data. Simultaneously, a timing module records time data for each operating mode. The control module, as the core, receives the preprocessed physical parameters and time data, generates maintenance control commands according to preset maintenance rules, and sends them to the execution module. The execution module performs maintenance operations on the generator car according to the commands and feeds back the results to the control module. The control module generates maintenance result information based on the feedback, which is displayed by a human-machine interface module. The human-machine interface module can also receive external maintenance commands and transmit them to the control module, thereby achieving automated control of the generator car's operation and maintenance. This device combines multi-dimensional data acquisition with intelligent control. It acquires physical parameters and time data through sensor and timing modules, respectively, providing a comprehensive basis for maintenance decisions. The introduction of preset rules enables the standardization and automation of maintenance control, reducing human judgment errors. The feedback mechanism between the execution and control modules ensures the traceability and accuracy of maintenance operations. The human-machine interaction module balances the flexibility of automated control and manual intervention, automatically generating maintenance instructions based on equipment status and allowing operators to input external instructions according to actual conditions, thus improving the timeliness and reliability of maintenance.

[0063] Please see Figure 2 , Figure 2 This is a hardware design for an automatic maintenance device for a generator car based on the above embodiments. The following is combined with... Figure 1 and Figure 2 Some other embodiments of the present invention will be described below.

[0064] In one embodiment of the present invention, the control module is specifically a microcontroller module, which is configured as follows:

[0065] The microcontroller's power-on circuit is activated the instant the generator's automatic maintenance device is powered on.

[0066] Based on the time data of each operating mode collected by the timing module and the data preprocessed by the data acquisition module, the current status of the generator car is determined and a set of maintenance control commands are generated.

[0067] The control execution module receives maintenance control commands and performs maintenance operations on the generator car in the order of the commands.

[0068] After the generator car completes the maintenance operation, it receives the execution results from the execution module, generates maintenance result information, and updates the maintenance status synchronously.

[0069] In this embodiment, the microcontroller module can be implemented using a microcontroller unit (MCU). Upon power-up, it utilizes its own circuit detection and control functions to detect the power-up signal after AC-DC power supply (external AC220V), triggering the power-on circuit to start and initiating the device's workflow. During operation, it receives real-time mode time data from the timing module via LORA communication, as well as sensor data (temperature, pressure, displacement, etc.) pre-processed by the data acquisition module, to determine whether the generator needs to perform the "idle-rated-idle-stop" process periodically, and then generates corresponding maintenance control commands. The commands are sent to the execution module, such as controlling relay switching to achieve idle / rated mode conversion, and regulating battery charging through the charging management module, executing maintenance actions in sequence. During execution, it continuously receives feedback from the execution module (such as whether charging is complete, whether mode switching is in place), combines the feedback to determine the operation results, generates maintenance result information including whether the maintenance process is complete, equipment parameter status, etc., and synchronously updates the maintenance status data within the device.

[0070] In one embodiment of the present invention, the sensor module includes a displacement sensor, and the corresponding external physical parameter is the displacement information of the generator throttle linkage.

[0071] Based on the time data collected by the timing module for each operating mode, and the data preprocessed by the data acquisition module, the current status of the generator car is determined and a set of maintenance control commands is generated, including:

[0072] In response to a preset maintenance cycle, a first maintenance control command is generated; the first maintenance control command is used to make the generator car run in idle mode for a first duration.

[0073] For example, the timing module continuously records the running time. When the accumulated time triggers a preset maintenance cycle (e.g., once a month / quarter), the MCU receives the cycle signal and simultaneously obtains the initial signal from the displacement sensor through the data acquisition module (confirming the initial position of the throttle linkage). Based on this, the MCU generates a first maintenance control command, which drives the throttle linkage to the corresponding position in the idle mode, causing the generator to enter idle operation, and simultaneously triggering the timing module to start counting the idle time.

[0074] Based on the idle running mode time collected by the timing module and the displacement information of the current generator car throttle linkage preprocessed by the data acquisition module, a second maintenance control command is generated; the second maintenance control command is used to make the generator car run in the rated running mode for a second time length.

[0075] For example, the timing module monitors the idling time and detects that it has reached the "first time length" (e.g., 3 minutes), and sends a time signal back to the MCU. Simultaneously, the data acquisition module continuously collects signals from the displacement sensor to confirm that the throttle linkage is stable within the idling displacement range. The MCU combines the time and displacement conditions to determine that the idling phase is complete and generates a second maintenance control command. This command switches the control relay, driving the throttle linkage to the rated mode position (increasing the load), the generator car switches to rated operation, and the timing module starts counting the rated duration (e.g., 30 minutes).

[0076] Based on the rated operating mode time collected by the timing module and the displacement information of the current generator car throttle linkage preprocessed by the data acquisition module, a third maintenance control command is generated; the third maintenance control command is used to make the generator car run in idle mode for a third time length.

[0077] For example, the timing module detects that the rated running time has reached the "second time length" (e.g., 30 minutes) and sends feedback to the MCU; the data acquisition module simultaneously verifies the stable signal of the throttle linkage at the rated displacement (confirming that the rated mode is fully executed). Based on this, the MCU generates a third maintenance control command, which controls the actuator to pull the throttle linkage back to the idle displacement, and the generator car idles again. The timing module records the duration of this stage (e.g., 2 minutes).

[0078] Based on the idle operation mode time collected by the timing module and the displacement information of the current generator car throttle linkage preprocessed by the data acquisition module, a shutdown command is generated.

[0079] For example, the timing module monitors the third idle time reaching the "third time length" (e.g., 2 minutes), and the displacement sensor confirms that the throttle linkage is in idle displacement and its state is stable (verifying that the transition mode has been executed correctly). The MCU determines that the timing and state of the entire process are satisfied, generates a stop command, cuts off power output (e.g., controls the engine to shut down), and completes the shutdown. The synchronous data acquisition module collects displacement, time, and other data to prepare for maintenance result feedback (e.g., generating a report).

[0080] In this embodiment, the control module uses displacement feedback and time verification as dual-dimensional control logic to replace manual judgment of the execution status, realizing unmanned and standardized execution of the entire process, greatly reducing labor costs and improving maintenance accuracy and efficiency.

[0081] In one embodiment of the present invention, the data acquisition module is further configured to: acquire the operating status data of the generator vehicle;

[0082] The operating status data includes the generator speed, output voltage, battery charge, and fuel level of the generator vehicle.

[0083] In this embodiment, the data acquisition module receives analog signals from sensors / detection circuits. These signals are first filtered (to remove electromagnetic interference, environmental noise, etc.), and then converted from analog to digital signals (analog electrical signals to digital signals) into digital data that the generator speed pulse signal, output voltage signal, battery charge electrical parameter signal, and fuel level signal can recognize and process by the MCU. Simultaneously, the module has a data caching function, allowing it to temporarily store the processed operating status data or transmit it to the MCU as needed.

[0084] In one embodiment of the present invention, a battery management module is further included, which is configured to:

[0085] When the data acquisition module detects that the battery power of the generator vehicle is lower than the preset lower limit, it automatically starts the charging program and controls the charging equipment to charge the battery.

[0086] Monitor battery parameters during charging and adjust charging strategies accordingly;

[0087] When the battery charge reaches the preset upper limit, the charging operation will automatically stop.

[0088] In this embodiment, the battery management module works collaboratively with the data acquisition module, the control module (MCU), and the charging equipment. First, the data acquisition module monitors the battery level in real time and transmits the data to the battery management module. When the battery level is detected to be below a preset lower limit, the battery management module triggers a preset charging program, controlling a relay or charging control circuit to start the charging equipment, outputting an appropriate charging current and voltage to the battery, and initiating the charging operation. During charging, the module continuously monitors key battery parameters, such as charging and discharging voltage, current, and battery temperature, using built-in sensors or detection circuits, and feeds these parameters back to the internal processing unit. Based on parameter changes, the module dynamically adjusts the charging strategy. For example, when the battery temperature is too high, it reduces the charging current to avoid overcharging or overheating and damaging the battery; when approaching full charge, it switches from constant current charging to constant voltage trickle charging to reduce battery wear. When the data acquisition module detects that the battery level has reached a preset upper limit, or detects abnormal parameters (such as a sudden voltage surge or excessive temperature), the battery management module immediately issues a command to control the charging equipment to stop the charging operation, completing one charging loop, and feeding back the charging results (such as charging time and final battery level) to the MCU to update the maintenance status.

[0089] In one embodiment of the present invention, the sensor module further includes a temperature sensor and a pressure sensor, which are used to collect the temperature and oil pressure of the generator vehicle, respectively.

[0090] In this embodiment, the temperature sensor is installed in key parts of the generator vehicle (such as the engine block, coolant tank, and battery surface) through direct or non-contact methods to sense temperature changes in these parts in real time. When the temperature rises or falls, the internal components of the sensor (such as the resistance value of the thermistor and the electromotive force of the thermocouple) change accordingly, converting the temperature signal into a transmittable voltage or current signal. The oil pressure sensor is installed in the engine oil circuit and is in direct contact with the oil. When the oil pressure changes, the sensor uses mechanical structures such as diaphragm deformation to drive the internal circuit (such as a piezoresistive element or piezoelectric crystal) to generate a change in electrical signal, converting the pressure value into an electrical signal output.

[0091] In one embodiment of the present invention, an alarm module is further included, which is configured to:

[0092] Receive alarm trigger signals from the control module; when the control module determines that the data collected by the sensor module and the data acquisition module is abnormal, it generates an alarm trigger signal.

[0093] An alarm is triggered and an alarm message is generated based on the alarm trigger signal.

[0094] In this embodiment, sensor modules (such as temperature sensors, pressure sensors, displacement sensors, etc.) collect the physical parameters (temperature, pressure, displacement, etc.) of the generator in real time. After preprocessing (filtering, analog-to-digital conversion, etc.) by the data acquisition module, the data is transmitted to the control module (MCU). The control module compares the received parameters with preset thresholds (such as safe temperature range, normal pressure range). When the data is determined to be outside the normal range (i.e., data abnormal), an alarm trigger signal (such as a high-level signal, a specific coded instruction) is immediately generated and sent to the alarm module.

[0095] Upon receiving a trigger signal, the alarm module activates its built-in audible and visual alarm components: a buzzer emits a continuous or intermittent audible alarm, an LED indicator flashes or remains constantly lit to emit a visual signal, and some modules can also simultaneously display text warnings (such as "overheating" or "abnormal oil pressure") on the display screen. Simultaneously, the module generates corresponding alarm information based on the type of trigger signal (such as abnormal temperature or abnormal pressure), records the time of the anomaly, related parameter values, and other details, and feeds the alarm information back to the control module, which then stores or transmits it to the human-machine interface.

[0096] In one embodiment of the present invention, a wireless module is further included, the wireless module being configured to:

[0097] The data processed and collected by the data acquisition module, as well as alarm information, are sent to the remote monitoring terminal.

[0098] In this embodiment, the data acquisition module preprocesses various parameters (temperature, pressure, rotational speed, power consumption, etc.) collected by the sensors and then transmits the processed operating status data to the control module. Simultaneously, alarm information generated by the alarm module is also fed back to the control module. The control module integrates and formats this data to conform to wireless transmission data specifications.

[0099] Subsequently, the wireless module receives the integrated data transmitted from the control module, modulates the digital signals into radio electromagnetic wave signals through its internal radio frequency circuitry, and transmits them using a preset wireless communication method (such as Wi-Fi connection to a local area network or 4G / 5G access to a mobile network). The remote monitoring terminal receives these signals through the corresponding wireless receiving module or network interface, demodulates and decodes them, and converts the data into visualized information (such as numerical values, charts, and alarm prompts) to display to the staff, realizing the remote real-time transmission of generator vehicle operation data and alarm information.

[0100] In one embodiment of the present invention, it further includes: a storage module, the storage module being configured to:

[0101] The storage sensor module collects the external physical parameters of the generator vehicle, and the data acquisition module collects the operating status data of the generator vehicle.

[0102] The storage timing module collects time data for each operating mode;

[0103] The module stores external maintenance commands and all feedback information received by the human-machine interaction module.

[0104] In this embodiment, the storage module receives data from various modules in real time, such as external physical parameters collected by the sensor module (e.g., raw data before displacement, temperature, and pressure signal preprocessing) and operating status data output by the data acquisition module (e.g., processed data such as speed and voltage). These data are transmitted to the storage module via the data bus. The time data of each operating mode recorded by the timing module (e.g., idle / rated running time), the external maintenance instructions received by the human-machine interaction module (e.g., manually input operation commands), and the feedback information generated by each execution stage (e.g., execution results and alarm records) are also forwarded to the storage module via the control module (MCU).

[0105] The storage module stores these data into corresponding data partitions (such as physical parameter area, status data area, time record area, and command feedback area) according to preset data structures and classification rules, and adds a timestamp to each data entry to ensure data timeliness and traceability. Simultaneously, the module has data read / write control functions, enabling real-time data storage, historical data retrieval, and batch export based on commands from the control module, meeting the device's requirements for long-term data retention and backtracking. It also provides information for display modules.

[0106] In addition, when the above-mentioned device is implemented, it can read real-time data (such as engine speed, fault codes, fuel injection quantity, etc.) from the original ECU (Electronic Control Unit) of the generator vehicle via the CAN bus to supplement the data collection dimensions of the sensor module; the control commands of the device (such as idle speed / rated mode switching, shutdown command, etc.) can be transmitted to the original ECU via the CAN bus to directly control the actuator of the generator vehicle, avoiding major modifications to the original vehicle circuit and improving compatibility and safety.

[0107] This invention also provides an automatic maintenance control method for generator cars, implemented based on the automatic maintenance device for generator cars as described in the foregoing embodiments, comprising the following steps:

[0108] Step 1: Power on and initialize the automatic maintenance device of the generator car.

[0109] For example, pressing the device's power switch button instantly activates the startup circuit upon the MCU monitoring device's power-on, transforming the maintenance work of the generator vehicle's automatic maintenance device from "complex steps" to an extremely simple "one-click" operation. The device completes internal circuit self-testing, parameter initialization, and startup preparation for each module (such as sensors, wireless modules, and human-machine interfaces).

[0110] Step 2: Collect the external physical parameters of the generator vehicle and perform preprocessing.

[0111] For example, temperature sensors, pressure sensors, and other sensors are installed in various key parts of the generator vehicle to monitor the operating status parameters such as temperature, humidity, and pressure of each component in real time; simultaneously, battery-related parameters such as battery voltage, charging and discharging current, and battery temperature are monitored. Data collected by various sensors is transmitted to the MCU via a wireless module, where the MCU performs preprocessing such as filtering and calibration to ensure data accuracy.

[0112] Step 3: Collect time data of the current operating mode of the generator vehicle.

[0113] For example, the device includes a timing module and a storage module. The timing module collects real-time data on the generator's operating time in different modes, such as idling and rated operating modes (e.g., idling duration, rated operating duration), and sends the time information to the MCU. The storage module then temporarily stores the data. The timing module synchronously tracks the maintenance cycle progress and sends a trigger signal to the MCU when the automatic maintenance cycle is reached.

[0114] Step 4: Based on the time data and the preprocessed data, generate a set of maintenance control instructions according to preset rules.

[0115] For example, the MCU receives the parameter data from step 2 (such as whether the battery voltage has reached the set value, and whether the operating parameters of each component exceed the threshold) and the time data from step 3 (such as the maintenance cycle has arrived, and the operating mode duration has reached the target), and analyzes it in conjunction with the preset rule base and knowledge base:

[0116] (1) If the automatic maintenance cycle is reached, generate a mode switching command of "idle for 3 minutes → rated operation for 30 minutes → idle for 2 minutes → shutdown";

[0117] (2) If the battery voltage is detected to be lower than the set value, a command to start the battery management module for charging is generated;

[0118] (3) If a component parameter exceeds the set threshold, an alarm command is generated;

[0119] (4) When the running time reaches the preset value, a control command to switch to the next mode is generated. The rule base and knowledge base are dynamically updated based on the historical maintenance data of multiple generator cars to ensure the optimality of the command.

[0120] Step 5: Perform the corresponding operations on the generator car according to the order of the maintenance control instructions, and obtain feedback information on the operation results.

[0121] For example, the MCU performs the following operations sequentially based on the generated maintenance control instructions:

[0122] (1) Control the displacement sensor to operate the throttle linkage of the generator car to switch between idle mode and rated mode, and complete the operation and shutdown operations according to the instruction sequence;

[0123] (2) Send a charging command to the battery management module. The battery management module starts the charging process and simultaneously provides real-time feedback on parameters such as charging and discharging voltage and current. When the battery is charged to the set value or an abnormality occurs, it provides feedback to stop charging or issue a warning signal.

[0124] (3) If the parameter exceeds the standard, trigger the alarm device (such as an audible and visual alarm) and record the abnormal parameter;

[0125] Step 6: Generate maintenance result information for the generator vehicle based on the feedback information.

[0126] For example, the MCU summarizes the operation feedback data from step 5 (such as the completion status of each mode, battery charging status, and abnormal alarm records), and combines it with the data recorded in the storage module, including the time, parameters, and effects of each maintenance operation (the data is immutable), to generate complete maintenance result information. Staff can view the maintenance results and various real-time data through a human-machine interface. The system automatically compares the real-time data with standard data under normal operating conditions and quickly generates corresponding maintenance decisions based on the current situation. The entire process requires no manual intervention; staff only need to start the device to be freed from tedious on-site operations and achieve intelligent operation. Simultaneously, the maintenance data will be updated to the rule base and knowledge base, helping the system to adaptively adjust and improve, providing an optimization basis for subsequent maintenance.

[0127] As can be seen from the above embodiments, the beneficial effect of the technical solution of the present invention lies in intelligent management. Intelligent management, based on automated management, has adaptive adjustment capabilities. Problem analysis and decision-making are both completed by the computer, significantly reducing the manual maintenance time of the generator car. Simultaneously, pressing the device switch button instantly activates the power-on circuit of the MCU monitoring device, transforming the maintenance work of the generator car's automatic maintenance device from "complex steps" to an extremely simple operation of "one-click access." It can achieve comprehensive real-time monitoring of the operating status parameters of the generator car at each maintenance stage. Furthermore, through various intelligent actuators, one-click automatic maintenance of the generator car can be achieved, realizing a high degree of automation in maintenance operations and effectively reducing manual operation time and steps. Moreover, multiple generator cars can be maintained simultaneously. After automatic maintenance, data is automatically read and a maintenance report is generated, which technicians can directly view through the human-machine interface.
