[0019] To enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this document.

[0020] Mobile generator sets, as a type of mobile power supply equipment, are widely used in emergency power supply, field operations, and communication support scenarios. Their core component, the generator set, directly affects the stability and reliability of the power supply. Currently, the generator set control system in mobile generator sets mostly adopts local monitoring, relying on on-site operators for data reading and fault diagnosis. This results in slow response times and information lag, especially in mobile power generation scenarios where wiring is difficult and monitoring range is limited. In recent years, wireless communication technology has been attempted for monitoring power generation equipment, but it still faces the following technical challenges: 1. Insufficient signal coverage and stability With the development of IoT technology, remote data transmission can be achieved using 4G modules, but this is unusable in areas without public network coverage (such as remote construction sites). Furthermore, relying on third-party communication services increases maintenance costs and compromises confidentiality. While Wi-Fi direct connection enables local wireless access, its signal coverage is typically less than 10 meters, making it difficult to meet the monitoring needs of operators at a safe distance from mobile generator sets.

[0021] 2. Poor adaptability to mobile environments Existing wireless monitoring equipment is prone to signal interruption under generator vibration and electromagnetic interference environments, and does not take into account the shielding effect of metal cabins on wireless signals, requiring repeated adjustment of antenna positions in practical applications.

[0022] Example 1 To address the aforementioned technical problems, this application proposes a remote control device for generator sets based on wireless communication, such as... Figure 1 As shown, it specifically includes: In this embodiment, the instruction sending module 101 is used to send instructions to the generator set monitoring module according to the PCL controller; the monitoring module 102 is used to obtain the status data of the generator set according to the instructions; and the wireless communication module 103 is used to place a directional antenna below the generator set chassis and transmit the status data of the generator set to the PC by adjusting the radiation angle of the directional antenna.

[0023] Specifically, the instruction sending module includes a PLC controller and a parallel controller. The PLC controller is the core data processing unit of the remote monitoring device. The PLC controller is wired to the monitoring module through an Ethernet interface. The PLC controller is then connected to the wireless communication module via a network cable. The wireless communication module sends data to the PC through a directional antenna, forming a wired-wireless hybrid communication structure. The parallel controller is responsible for obtaining the cumulative power generation of the generator set and transmitting it to the PLC controller. During the generator set power supply process, the PLC controller sends data aggregation instructions to the monitoring module. The generator set monitoring module includes various operating sensors such as current sensors, voltage sensors, frequency sensors, oil level sensors, and temperature sensors. After receiving the instructions, the PLC controller uses the sensors to acquire various indicator data of the generator set, including voltage, current, frequency, oil level, temperature, speed, and liquid level status data. The status data is transmitted to the PLC controller in real time. The PLC controller transmits the status data to the wireless communication module via a network cable. The wireless communication module transmits the status data to the PC via a directional antenna. After receiving the status data, the PC uses various threshold indicators for reference and comparison, and displays various status data as data curves on the display screen. This allows for better observation of the generator set's operating status, ensuring the normal operation of the generator set. Users can also use this data to promptly detect and identify dangerous conditions and initiate emergency shutdown in a timely manner.

[0024] This application achieves stable signal transmission within the generator vehicle through a wired-wireless hybrid communication framework and significantly expands the wireless monitoring range, enabling stable passage within a 70-meter range, which is far superior to existing Wi-Fi direct connection solutions.

[0025] In this embodiment, the device further includes a connection module, wherein the PCL controller is connected to the wireless communication module via a network cable; the network cable is a KGGRP industrial-grade composite shielded cable; the KGGRP industrial-grade composite shielded cable consists of a tin-plated copper conductor, a cross-linked polyethylene insulation layer, an aluminum foil wrapping layer, a double-layer silver-plated copper wire braided shielding layer, and a flame-retardant polyurethane sheath.

[0026] Specifically, the PCL controller connects to the wireless communication module via a network cable. The wireless communication module sends data to the PC, thus forming a wired-wireless hybrid communication structure. The network cable is a KGGRP cable, which includes multiple strands of tinned copper core conductors, an aluminum foil wrapping layer, and a double-layer silver-plated copper wire braided shielding layer, and is covered with an oil-resistant and flame-retardant polyurethane sheath.

[0027] This application, through the selection of cables, enables the system to maintain stable communication even in the strong electromagnetic interference environment where the generator is located, thereby improving the equipment's adaptability to complex operating environments. Each layer of the cable has the following functions: multi-strand tin-plated copper conductors reduce high-frequency skin loss; cross-linked polyethylene insulation layer withstands 3kV and suppresses electromagnetic radiation; aluminum foil wrapping layer provides shock absorption and shielding; double-layer silver-plated copper wire braided shielding layer resists interference; and flame-retardant polyurethane sheath resists oil and mechanical wear, enabling the cable to be used for a long time in high interference, high temperature, and high vibration environments.

[0028] In this embodiment of the application, the connection module further includes a cable with one end connected to the RJ45 Ethernet interface of the PCL controller and the other end connected to the LAN port of the VS705WD industrial-grade wireless router.

[0029] Specifically, the cable is led out from the PLC's RJ45 Ethernet interface and connected to the LAN port of the VS705WD industrial-grade wireless router. This application solves the technical problems of strong electromagnetic interference, fragile cables, and signal distortion during generator operation. It enhances the signal anti-interference capability by using high-quality shielded cables, ensuring that the data collected by the PLC is not damaged during transmission, guaranteeing the stability of the communication link and the reliability of the system, and enabling the key data collected by the PLC to be transmitted to the wireless communication module with high quality.

[0030] In this embodiment, the device further includes a shock-absorbing module, wherein the wireless communication module is installed in a preset shock-absorbing area according to the shock-absorbing bracket; the shock-absorbing bracket includes a rubber layer and a steel structure.

[0031] Specifically, the generator truck experiences strong mechanical vibrations and high-frequency impacts during operation. This application incorporates a specialized design for the wireless module installation structure. The wireless module is fixedly installed using a combination of rubber pads and steel structure vibration-damping supports, forming a combined rigid and flexible anti-vibration installation method. Simultaneously, all connecting cables are properly laid out using nylon cable ties and cable trays to prevent shaking, friction, or pull-out. This effectively overcomes the risks of poor contact, module loosening, or damage caused by vibration during operation, ensuring the structural stability and communication continuity of the equipment during long-term outdoor operation, thereby improving the environmental adaptability and service life of the entire system.

[0032] In this embodiment, the instruction sending module further includes a PCL controller with one end connected to a sensor and the other end establishing a signal channel with a digital signal source; the sensor includes a voltage sensor, a current sensor, a frequency sensor, an oil level sensor, and a temperature sensor. Based on the sensors, the digital signal source, the PCL controller, and preset standard parameters, the operating status of the generator set is monitored to determine parameters exceeding the standard; based on the parameters exceeding the standard and the digital signal source, the generator set is shut down.

[0033] Specifically, one or two PLC controllers are deployed in the generator truck's control cabinet, serving as the core data acquisition and processing unit. The PLC connects to operating sensors such as voltage, current, frequency, oil level, and temperature via its analog input interface. It also establishes signal channels with some digital signal sources (such as fault status and emergency stop buttons). After transmitting these parameters exceeding limits to the PC, the user can shut down the generator based on past experience or the specific circumstances, thus enabling real-time monitoring and judgment of the generator set's operating status. The key to this step is utilizing the PLC to automate the generator's operating status management, solving the problems of traditional generator trucks relying solely on manual data reading and lacking real-time accuracy. This provides a stable and reliable data source for remote communication.

[0034] In this embodiment of the application, the wireless communication module further includes a directional antenna placed in an open area below the generator set chassis via a directional lead, and the installation angle of the directional antenna is adjusted to a preset angle.

[0035] Specifically, the signal antenna of the wireless communication module is extended from inside the cabin to the open area under the generator chassis via a coaxial high-frequency lead. The antenna is an adjustable directional antenna, installed on the outside of the metal structure, and its azimuth and elevation angles can be adjusted according to the usage scenario. By adjusting the radiation angle, the signal can effectively penetrate the metal cabin, forming a stable wireless coverage area with a radius of 70 meters.

[0036] This application solves the signal blind zone problem caused by the shielding effect of the metal enclosure, significantly improving the wireless signal coverage capability. It enables operators to remotely access and monitor the status of the equipment from a safe distance without having to get close to it. It is particularly suitable for power generation equipment applications in high temperature, noisy, toxic or dangerous environments, and meets the needs of personnel to grasp the operating status of the equipment without getting close to it during field operations.

[0037] In this embodiment of the application, the wireless communication module further includes creating an independent local Wi-Fi signal; the user on the PC connects to the Wi-Fi signal to view the status data of the generator set.

[0038] Specifically, the wireless communication module can create an independent local Wi-Fi signal when transmitting data, which end users can connect to using laptops, industrial tablets, or mobile devices. By logging into the web-based control interface via a browser or installing an app, users can view real-time operating parameters, historical data curves, fault alarm records, and cumulative operating time, and perform user permission management, parameter settings, and data export. This effectively avoids the limitation of relying on public network signals, enabling remote local monitoring in remote areas without 4G / 5G signals. It also provides maintenance personnel with a convenient means to monitor equipment status anytime, anywhere, significantly improving the efficiency and safety of power generation equipment management.

[0039] Example 2 This application provides a method for remote monitoring of generator sets based on wireless communication, including the following steps: Acquire the status data of the generator set; transmit the status data to the PC terminal according to the directional antenna and PLC controller.

[0040] Specifically, when the mobile generator is used for emergency power supply in the field, it connects directly to an industrial-grade wireless router via a network cable from the PLC controller, forming a wired-wireless hybrid communication method. When transmitting data to the PC, the PLC controller first issues an acquisition command to the generator set. The sensors transmit the status data of the generator set to the PLC controller, which then uses the network cable to transmit the status data to a directional antenna. The directional antenna transmits the status data to the PC at a certain angle, thereby maximizing the monitoring needs of operators at a safe distance from the mobile generator set.

[0041] Example 3 This application provides a wireless communication remote monitoring system for generator sets suitable for mobile generator vehicles, particularly applicable to remote monitoring and control scenarios for generator sets in environments with high vibration and high electromagnetic interference. Its core lies in constructing a composite structure consisting of a PLC controller, an industrial wireless module, dedicated anti-interference cables, a vibration-resistant bracket, and a directional antenna, effectively improving the system's stability and adaptability in complex environments.

[0042] like Figure 2 As shown, the system mainly consists of a generator set monitoring module, a PLC controller, and a VS705WD industrial wireless module. The generator set monitoring module includes modules for oil level monitoring, power generation monitoring, historical alarm recording, and data curve analysis. This monitoring data is collected and processed by the PLC controller and transmitted to the wireless module via a wired connection.

[0043] This invention overcomes the problems of difficult wiring, numerous blind spots in monitoring, and slow response in traditional systems. It adopts a wired-wireless hybrid communication structure: the PLC controller is connected to the wireless module via a network cable, the wireless module transmits data, and the PC terminal can achieve contactless remote access and control within a range of 70 meters, forming a stable and reliable mobile power supply information platform. Figure 2 The dashed circle in the middle indicates the coverage area of ​​the wireless signal. Each PC can achieve stable communication with the wireless module from a safe distance, meeting the needs of personnel to monitor the operating status of the equipment without approaching it during field operations.

[0044] like Figure 3 As shown, the connection cable used between the PLC controller and the wireless module is a KGGRP industrial-grade composite shielded cable. This cable structure includes a double-layer shielding layer (aluminum foil + braided mesh), multi-strand tinned copper core conductors, and a high-flame-retardant cross-linked polyethylene sheath. It possesses excellent resistance to high-frequency electromagnetic interference and can operate stably for extended periods under harsh conditions such as high temperature, oil contamination, and vibration during generator vehicle operation. This cable effectively improves the reliability of critical signal transmission links and is one of the key supporting components enabling the implementation of this invention in complex scenarios.

[0045] like Figure 4 As shown, to address the challenges of severe vibration in generator vehicles and signal shielding by metal structures, this invention employs a seismic-resistant support structure and antenna signal deployment method: An industrial-grade wireless module is installed in the vibration-damping zone using a vibration-damping bracket. Simultaneously, KGGRP cables extend the antenna signal to an open area under the generator vehicle chassis. The antenna utilizes a directional angle adjustment structure; by adjusting its installation angle, the signal is ensured to penetrate the metal shielding area of ​​the vehicle body, ultimately achieving stable wireless coverage within a 70-meter radius. Through this structure, this invention effectively solves the following problems existing in traditional remote monitoring of generator vehicles: (1) The wireless signal coverage is small, and there are many blind spots in monitoring; (2) Frequent signal interruptions occur under strong vibration and high electromagnetic interference; (3) The metal cabin obstructs communication, leading to instability; (4) Poor adaptability to complex outdoor environments.

[0046] This application provides a storage medium for storing computer-executable instructions, characterized in that the computer-executable instructions, when executed, implement the steps of the wireless communication-based remote monitoring method for generator sets as described in any of the above embodiments.

[0047] It should be noted that the embodiments concerning the storage medium in this specification and the embodiments concerning the remote monitoring method for generator sets based on wireless communication in this specification are based on the same inventive concept. Therefore, the specific implementation of this embodiment can be referred to the aforementioned implementation of the corresponding remote monitoring method for generator sets based on wireless communication, and the repeated parts will not be described again.

[0048] The foregoing has described specific embodiments of this specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in a different order than that shown in the embodiments and may still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired result. In some embodiments, multitasking and parallel processing are possible or may be advantageous.

[0049] In the 1930s, improvements to a technology could be clearly distinguished as either hardware improvements (e.g., improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the methodology). However, with technological advancements, many improvements to the methodology today can be considered direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved methodology into the hardware circuit. Therefore, it cannot be said that an improvement to the methodology cannot be implemented using hardware physical modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. Designers can program and "integrate" a digital system onto a PLD themselves, without needing chip manufacturers to design and manufacture dedicated integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing integrated circuit chips, this programming is mostly implemented using "logic compiler" software. Similar to the software compiler used in program development, the original code before compilation must also be written in a specific programming language, called a Hardware Description Language (HDL). There are many HDLs, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, and RHDL (Ruby Hardware Description Language). Currently, the most commonly used are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also understand that by simply performing some logic programming on the method flow using one of these hardware description languages ​​and programming it into an integrated circuit, the hardware circuit implementing the logical method flow can be easily obtained.

[0050] The controller can be implemented in any suitable manner. For example, it can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicon Labs C8051F320. A memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also recognize that, in addition to implementing the controller in purely computer-readable program code form, the same functionality can be achieved by logically programming the method steps to make the controller take the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.
