Description

Technical Field

[0001] This invention belongs to the field of engineering project machinery and equipment management technology, and in particular relates to a method and system for managing fuel consumption of engineering machinery and equipment. Background Technology

[0002] In large-scale engineering projects such as open-pit mine earthwork stripping, road and bridge construction, and construction site construction, machinery and equipment such as excavators, loaders, dump trucks, and road rollers are core productivity tools, and fuel consumption management is directly related to project cost control, efficiency optimization, environmental compliance, and equipment maintenance.

[0003] Currently, fuel consumption cannot be directly obtained. Taking the daily cost analysis and calculation of a mining earthwork stripping project as an example, the remaining fuel level in the tank after a day's work is unclear, leading to inaccurate cost estimates. For instance, if work is suspended due to weather conditions immediately after refueling, the amount of fuel used will be incorrect for the subsequent unit cost. Furthermore, it is impossible to promptly investigate and address abnormal vehicle consumption (such as idling or operation during non-working hours) or fuel consumption spikes caused by equipment malfunctions. Moreover, fuel consumption prediction through models or other methods is not only complex but also subject to discrepancies between predicted and actual fuel consumption due to factors such as vehicle age and equipment wear. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a fuel consumption management method and system for construction machinery. First, it acquires the fuel consumption of the electronic control unit (ECU) within the construction machinery, enabling direct acquisition of fuel consumption and ensuring accurate cost calculations, along with the corresponding refueling data from the refueling nozzle. Then, if the absolute value of the difference between the ECU's fuel consumption and the refueling data from the refueling nozzle exceeds a preset value within a preset time period, an alarm command is issued, enabling the detection of abnormal situations such as soaring fuel consumption. Furthermore, the fuel consumption of the ECU is corrected based on the amount of fuel added between two refueling sessions to fill the machinery, and the amount added during the second refueling session, thus resolving the problem of fuel consumption calculation errors caused by vehicle age and equipment wear.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a method for fuel consumption management of engineering machinery equipment, comprising: If the absolute value of the difference between the fuel consumption of the electronic control unit and the refueling data of the fuel nozzle is greater than the preset value within a preset time period, an alarm command will be issued to remind relevant personnel to check for abnormal conditions such as fuel theft and / or fuel leakage. If there are no abnormal conditions such as fuel theft and / or fuel leakage, the fuel consumption of the electronic control unit will be corrected based on the amount of fuel added between two refueling sessions to fill up the construction machinery equipment and the amount added during the second refueling session. Fuel consumption is calculated using the corrected electronic control unit's fuel consumption data.

[0006] Furthermore, the fuel consumption of the corrected electronic control unit. for: ; in, To calculate the fuel consumption of the electronic control unit within a given time period; This refers to the amount of fuel dispensed by the fuel nozzle when the tank is filled up for the second time. The amount of fuel dispensed between the first and second full tanks is recorded separately by the fuel pump. This refers to the fuel consumption of the electronic control unit during the time between the first and second refueling.

[0007] Furthermore, as the vehicle's service life increases, the degree of equipment wear increases, and the number of historical alarms increases, the correction frequency of fuel consumption by the electronic control unit should be increased, and the time interval between the first and second full tanks should be shortened.

[0008] Furthermore, when the vehicle's service life increases by a preset time, and / or when the equipment wear increases, and / or when the number of historical alarms increases, the correction frequency increases, and the time interval between the first and second full tanks is shortened.

[0009] Furthermore, the wear and tear of the equipment is determined by the magnitude of vibration during equipment operation.

[0010] Furthermore, by comparing the fuel consumption data of the same construction machinery equipment horizontally, if the difference in fuel consumption data is greater than the preset value at the same time point or within the same time period on the same day, a reminder will be issued.

[0011] Secondly, the present invention also provides a fuel consumption management system for engineering machinery equipment, comprising: The data acquisition module is configured to: acquire the fuel consumption of the electronic control unit in the construction machinery equipment, as well as the refueling data of the corresponding refueling gun of the construction machinery equipment; The correction module is configured to: when the absolute value of the difference between the fuel consumption of the electronic control unit and the refueling data of the fuel nozzle is greater than a preset value within a preset time period, issue an alarm command to remind relevant personnel to check for abnormal conditions such as fuel theft and / or fuel leakage; if there are no abnormal conditions such as fuel theft and / or fuel leakage, the fuel consumption of the electronic control unit is corrected based on the amount of fuel added between two refueling sessions to fill the construction machinery equipment and the amount added during the second refueling session. The calculation module is configured to calculate the fuel consumption cost using the corrected fuel consumption of the electronic control unit.

[0012] Thirdly, the present invention also provides a computer-readable storage medium having a computer program stored thereon that, when executed by a processor, implements the steps of the fuel consumption management method for engineering machinery equipment described in the first aspect.

[0013] Fourthly, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the program to implement the steps of the fuel consumption management method for engineering machinery equipment described in the first aspect.

[0014] Fifthly, the present invention also provides a computer program product, the computer program product comprising a computer program, which, when executed by a processor, implements the steps of the fuel consumption management method for engineering machinery equipment described in the first aspect.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, firstly, the fuel consumption of the electronic control unit in the construction machinery is obtained, enabling direct acquisition of fuel consumption and ensuring the accuracy of cost calculation, as well as the corresponding refueling data of the refueling nozzle of the construction machinery. Then, if the absolute value of the difference between the fuel consumption of the electronic control unit and the refueling data of the refueling nozzle is greater than a preset value within a preset time period, an alarm command is issued, enabling the investigation of abnormal situations such as soaring fuel consumption. Furthermore, the fuel consumption of the electronic control unit is corrected based on the amount of fuel added between two refueling sessions to fill the construction machinery and the amount added during the second refueling session, thus solving the problem of fuel consumption calculation errors caused by vehicle age and equipment wear.

Fuel nozzle body; 2. Display screen and buttons; 3. RFID card reader; 4. RFID tag; and 5. Fuel tank. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] OBD (On-Board Diagnostics) is a standardized computerized system integrated into a vehicle to monitor the real-time operating status of the engine, emission control system, and other critical components. This system provides diagnostic trouble codes (DTCs) and vehicle operating data through diagnostic interfaces (such as OBD-II), supporting fault detection, maintenance assistance, and environmental compliance verification. Modern OBD systems typically conform to international standards (such as ISO 15031) and support communication with external diagnostic equipment.

[0021] An ECU (Electronic Control Unit) is an embedded computer device in a vehicle used to control specific subsystems or functions. It typically consists of a microprocessor, memory, and input / output interfaces. Depending on its function, an ECU may include an Engine Control Module (ECM), a Transmission Control Module (TCM), etc. The ECU collects data from sensors and executes pre-programmed algorithms to adjust actuators (such as fuel injection and ignition timing) to ensure the efficient and safe operation of the vehicle system.

[0022] RFID tags (Radio-Frequency Identification Tags) are electronic devices that use radio waves to achieve contactless data storage and transmission. They consist of a microchip and an antenna. Tags can be divided into passive (powered by a reader / writer) and active (with an internal battery), and their operating frequency bands include low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). In vehicle applications, RFID tags can be used for component tracking, identification, or interaction with onboard systems (such as OBD) to achieve automated data collection or anti-theft functions.

[0023] Example 1: In large-scale engineering projects such as open-pit mine earthwork stripping, road and bridge construction, and construction site construction, mechanical equipment (such as excavators, loaders, dump trucks, road rollers, etc.) are core productivity tools, and fuel consumption management is directly related to project cost control, efficiency optimization, environmental compliance, and equipment maintenance.

[0024] In existing construction projects, fuel consumption management is relatively crude and lacks a complete system. Most of the management is done through manual recording, that is, after the driver or gas station attendant refuels, the refueling information (fuel volume, time, etc.) is recorded manually. Some construction units with the necessary resources will use integrated refueling machines, which can record the amount of fuel dispensed and then summarize it periodically.

[0025] However, whether manual or automated fuel dispenser recording is used, only the amount of fuel dispensed can be recorded; fuel consumption cannot be obtained. Taking the daily cost analysis of a mining earthwork stripping project as an example: after a day of operation, the remaining fuel level in the tank is unclear, leading to inaccurate cost estimates. In extreme cases, if work is halted due to weather conditions immediately after refueling, using the refueling amount for subsequent unit costs will undoubtedly be incorrect. Furthermore, abnormal vehicle consumption (such as idling or operation outside of working hours) or sudden spikes in fuel consumption due to equipment malfunctions cannot be promptly investigated.

[0026] Based on this, this embodiment provides a fuel consumption management method for construction machinery equipment. It can automatically collect not only vehicle refueling data but also real-time fuel consumption data and automatically process the relevant data. The method in this embodiment includes: First, using a data acquisition module to collect the fuel consumption of the electronic control unit in the construction machinery equipment, as well as the refueling data from the corresponding refueling nozzle; then, if the absolute value of the difference between the fuel consumption of the electronic control unit and the refueling data from the refueling nozzle exceeds a preset value within a preset time period, an alarm command is issued to remind relevant personnel to investigate whether there are abnormal operating conditions such as fuel theft or leakage; if no abnormal operating conditions such as fuel theft or leakage are found, the fuel consumption of the electronic control unit is corrected based on the amount of fuel added between two refueling sessions to fill the construction machinery equipment, and the amount added during the second refueling; finally, the fuel consumption of the electronic control unit is used to obtain the fuel usage cost.

[0027] This embodiment enables direct acquisition of fuel consumption, ensuring the accuracy of cost calculation. It also enables the detection of abnormal situations such as soaring fuel consumption through alarms. Furthermore, it corrects the fuel consumption of the electronic control unit based on the amount of fuel added between two refueling sessions to fill up the construction machinery equipment, as well as the amount added during the second refueling session. This solves the problem of fuel consumption calculation errors caused by factors such as vehicle age and equipment wear.

[0028] In some embodiments, the fuel consumption of the electronic control unit may differ from the actual fuel consumption due to vehicle age, equipment wear and tear, etc. Therefore, the fuel consumption data for this period is corrected by calculating the amount of fuel added between two full tanks and the amount added during the second full tank. For example, if 300L was added during the second full tank, and 800L was added between the first and second full tanks, the fuel consumption collected during this period is 1000L. Then, the subsequent fuel consumption data of the vehicle = fuel consumption data read by the ECU × [(300 + 800)] ÷ 1000. This is corrected periodically based on the difference between the subsequent actual fuel consumption and the collected fuel consumption data. Optionally, the corrected fuel consumption of the electronic control unit... for: ; in, To calculate the fuel consumption of the electronic control unit within a given time period; This refers to the amount of fuel dispensed by the fuel nozzle when the tank is filled up for the second time. The amount of fuel dispensed between the first and second full tanks is recorded separately by the fuel pump. This refers to the fuel consumption of the electronic control unit during the time between the first and second refueling.

[0029] In some embodiments, as the vehicle's service life, the degree of equipment wear, and the number of historical alarms increase, the correction frequency of the electronic control unit's fuel consumption is increased, and the time interval between the first and second refueling is shortened to improve the accuracy of fuel consumption detection. Optionally, for every preset increase in vehicle service life, every preset increase in equipment wear level, and / or every preset increase in the number of historical alarms, the correction frequency is increased by a preset frequency value, and the time interval between the first and second refueling is shortened by a preset duration. Since more severe wear results in greater vibration during equipment operation, the equipment wear condition is determined by the magnitude of vibration during equipment operation; alternatively, the degree of wear is determined using other wear detection technologies.

[0030] In some embodiments, fuel consumption data of construction machinery equipment under the same working conditions and of the same model are compared horizontally. If the difference in fuel consumption data of the same equipment is greater than a preset value at the same time or within the same period of the same day, a reminder is issued; reminding users to pay attention to whether there are differences in the driver's skills, or whether there is violent driving or lazy work behavior.

[0031] Example 2: Based on Example 1, in order to support Example 1, this example provides a fuel consumption management method and system for engineering machinery equipment. The hardware mainly includes an on-board intelligent terminal and an intelligent fuel dispenser, and the software mainly includes a fuel consumption management platform and a corresponding correction algorithm.

[0032] The intelligent vehicle terminal is an electronic device with data acquisition and data upload functions. It connects to the vehicle that needs to collect fuel consumption data through the OBD interface, reads the fuel consumption data and working time data in the vehicle ECU, and uploads the fuel consumption data and working time data at various times to the fuel consumption management platform.

[0033] The intelligent fuel dispenser includes an intelligent fuel dispenser body 1, a display screen and buttons 2, an RFID reader 3, an RFID tag 4, and a fuel tank 5. The intelligent fuel dispenser body 1 contains a flow meter and a data upload module. The flow meter records the amount of fuel dispensed, and the data upload module uploads the refueling information to the fuel consumption management platform. The display screen and buttons 2 can display the current refueling information, and the buttons can be used to modify the type of fuel dispensed (e.g., 0# diesel, 95# gasoline). The RFID tag 4 is fixed to the fuel tank opening (fuel tank 5) of the vehicle, and the tag records the vehicle information, such as the vehicle number and license plate number. The RFID reader 3 can read the vehicle information recorded on the RFID tag 4 and upload it to the fuel consumption management platform through the data upload module in the intelligent fuel dispenser body 1.

[0034] The fuel consumption correction algorithm is an algorithm that uses the amount of fuel added to correct fuel consumption. The fuel consumption data read by the intelligent vehicle terminal 1 through the OBD interface may differ from the actual fuel consumption due to the vehicle's age and equipment wear. Therefore, the fuel consumption data during this period is corrected by calculating the amount of fuel added between two full fill-ups. For example, if 300L was added during the second fill-up and 800L was added between the first and second fill-ups, the fuel consumption collected during this period is 1000L. Then, the subsequent fuel consumption data of the vehicle = fuel consumption data read by the ECU × [(300+800)] ÷ 1000. The algorithm is periodically corrected based on the difference between the subsequent actual fuel consumption and the collected fuel consumption data.

[0035] The fuel consumption management platform can automatically aggregate refueling and fuel consumption data for each vehicle, automatically calculate the fuel cost of each vehicle, and analyze the fuel consumption data of each vehicle at different times. It can also perform a horizontal comparison of the refueling amount and fuel consumption of the equipment. If the difference is small, a correction algorithm is activated; if the difference is too large, an alarm is issued to remind the user to pay attention to factors such as fuel theft or leakage. Furthermore, it can perform a horizontal comparison of the fuel consumption data of the same model of equipment under the same operating conditions. For the same model of equipment with excessively large differences in fuel consumption, it is marked to remind the user to pay attention to whether there are differences in the driver's skills, or whether there is aggressive driving or lazy work behavior.

[0036] In some embodiments, a file is created for the vehicles that need to be managed on the fuel consumption management platform, and an in-vehicle smart terminal is installed and bound to the corresponding vehicle equipment. The in-vehicle smart terminal is equipped with an OBD port, which can be plugged into the OBD interface of the vehicle equipment to read the vehicle ECU data; vehicle information is written to the RFID tag and fixed to the fuel tank opening of the corresponding vehicle; the smart refueling nozzle replaces the existing refueling equipment or a new refueling equipment and is bound to the fuel consumption management platform.

[0037] In some embodiments, when using a smart refueling nozzle, on-site refueling personnel use an RFID reader to read the vehicle information from the RFID tag at the fuel tank opening. After refueling, they upload the refueling data to the fuel consumption management platform via a data upload module. The smart vehicle terminal continuously reads the vehicle's ECU data and uploads it to the fuel consumption management platform. The fuel consumption management platform automatically aggregates the vehicle's refueling and fuel consumption data, uses the refueling data to correct the fuel consumption data, and ultimately presents the user with corresponding aggregated fuel consumption information. It also alerts users to vehicles with abnormal fuel consumption.

[0038] In some embodiments, the functions of flow metering, data uploading, and RFID vehicle information reading are all integrated into the fuel dispenser. Wireless data transmission technologies such as Bluetooth, NFC, and Zigbee are used instead of RFID. Intelligent vehicle terminals generally refer to any electronic device that uses the OBD interface to read ECU fuel consumption data.

[0039] This embodiment demonstrates the high adaptability of the intelligent fuel dispenser. For any existing refueling equipment, simply replacing the dispenser enables fully automated fuel collection and statistics (vehicle information, fuel volume, refueling time, etc.), overcoming the shortcomings of traditional integrated fuel dispensers which are bulky, difficult to move, and challenging to deploy on refueling trucks. Regarding fuel consumption data collection, it innovatively uses an OBD interface to obtain fuel consumption data from the vehicle's ECU and periodically corrects the data based on the fuel volume. For fuel consumption management, it automatically collects data such as fuel volume and fuel consumption and uploads it to a fuel consumption management platform for automatic aggregation and analysis, eliminating false reporting, misreporting, underreporting, and statistical errors that occur during manual reporting, statistics, and aggregation. Furthermore, in heavy machinery-dependent engineering projects, fuel consumption management is the linchpin of the cost-efficiency-management triangle. Through refined control, companies can reduce fuel consumption per unit, directly improving project profitability.

[0040] Example 3: This embodiment provides a fuel consumption management system for engineering machinery equipment, including: The data acquisition module is configured to: acquire the fuel consumption of the electronic control unit in the construction machinery equipment, as well as the refueling data of the corresponding refueling gun of the construction machinery equipment; The correction module is configured to: when the absolute value of the difference between the fuel consumption of the electronic control unit and the refueling data of the fuel nozzle is greater than a preset value within a preset time period, issue an alarm command to remind relevant personnel to check for abnormal operating conditions such as fuel theft or leakage; if there are no abnormal operating conditions such as fuel theft or leakage, the fuel consumption of the electronic control unit is corrected based on the amount of fuel added between two refueling sessions to fill up the construction machinery equipment and the amount added during the second refueling session. The calculation module is configured to calculate the fuel consumption cost using the corrected fuel consumption of the electronic control unit.
