Description

Technical Field

[0001] The present invention relates to a fluid proportioning logistics operation system and method. Background Art

[0002] CNC machine tools are the most important type of processing equipment in the equipment manufacturing industry, widely used in fields such as aviation, aerospace, shipbuilding, and automotive molds, earning them the reputation of being the "mother machine of industry." Metalworking fluids, such as cutting fluids, lubricants, and coolants, are crucial auxiliary components of CNC machine tools. They reduce cutting heat, clean part surfaces, and provide lubrication and rust prevention, thereby ensuring the quality of machined parts. Because the chips generated by CNC machine tools during cutting remove a significant amount of cutting fluid, and are susceptible to leakage and volatilization, the cutting fluid volume and concentration decline over extended production periods. Furthermore, prolonged use of CNC machine tools can lead to a continuous decrease in lubricants, coolants, and other metalworking fluids, necessitating the timely addition of appropriate metalworking fluids to ensure proper operation.

[0003] When existing factories replenish metalworking fluids, they usually manually notify suppliers of the type and quantity of the corresponding metalworking fluids. The suppliers then distribute the metalworking fluids according to the factory's requirements. This not only reduces supply efficiency but also increases the logistics and transportation costs of the metalworking fluids. At the same time, each replenishment of metalworking fluids needs to be manually recorded, which can easily lead to data loss or falsification, resulting in unnecessary waste of metalworking fluids. Summary of the Invention

[0004] The purpose of the present invention is to provide a technical solution for a fluid proportioning logistics operation system and method to address the shortcomings of the existing technology. Through the design of the liquid storage terminal, cloud platform and vehicle-mounted terminal, not only can the rapid transmission of fluid information be achieved, but also the required vehicle can be accurately matched, and the vehicle closest to the liquid storage terminal can be selected. At the same time, it is beneficial for suppliers to plan the fluid transportation route, improve the efficiency of fluid proportioning logistics operations, and reduce transportation costs. The usage method is simple in steps, which can not only improve the work efficiency of the entire fluid proportioning logistics operation system, but also reduce the errors caused by manual operation, optimize the path between the vehicle and the liquid storage terminal, improve supply efficiency, reduce operating costs, and enhance customer experience. It can be set up in various oil-using enterprises, and enterprises can consume various types of oil products according to their own needs. The oil supply and oil product monitoring data of the intelligent supply system set up by each enterprise will also be transmitted to the cloud for storage and analysis, which can not only directly reduce the logistics, storage, sales and packaging costs of metalworking fluid products for customers, but also provide customers with more accurate and high-quality services through Internet of Things big data analysis.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A fluid proportioning logistics operation system, characterized by:

[0007] a liquid storage terminal for issuing a fluid information request;

[0008] The cloud platform is used to receive the fluid information request and location information of the liquid storage terminal from the liquid storage terminal, match the vehicle terminal according to the fluid information request and location information, or collect and predict the fluid information of the liquid storage terminal, and send instructions to the vehicle terminal. The fluid information refers to the interval filling time and filling amount;

[0009] The vehicle-mounted terminal is used to receive and obtain instructions from the cloud platform or fluid information requests from the liquid storage terminals around the vehicle-mounted terminal, and plan a path based on the current position of the vehicle or receive path instructions sent by the cloud platform to the liquid storage terminal.

[0010] Through the design of liquid storage terminals, cloud platforms and vehicle-mounted terminals, not only can the rapid transmission of fluid information be achieved, but the required vehicles can also be accurately matched, and the vehicle closest to the liquid storage terminal can be selected. At the same time, it is beneficial for suppliers to plan the fluid delivery routes, improve the efficiency of fluid proportioning logistics operations, and reduce transportation costs.

[0011] Furthermore, the liquid storage terminal includes a first controller, a first signal transceiver, a first data storage device, and a first sensor connected to the first liquid storage device;

[0012] The first sensor is connected to the first signal transceiver device through the first controller, and the first controller is connected to the first data storage device. The first sensor monitors the liquid level information of the first liquid storage device and transmits it to the first controller. The first controller is used to send the liquid level information and the position information of the first liquid storage device to the cloud platform via the first signal transceiver device; the first controller can accurately transmit the type information of the fluid in the first liquid storage device, the remaining amount of fluid and the required amount of fluid to the cloud platform via the first signal transceiver device. The cloud platform first selects and matches the vehicle, and then selects the vehicle closest to the liquid storage terminal, thereby improving the efficiency of logistics operations and effectively avoiding the risk of fluid transportation errors. The first data storage device is used to store real-time filling data information to avoid the inability to upload data due to signal interruption.

[0013] Furthermore, the first liquid storage device is connected to a connector matching alarm device for checking the matching degree when the pipeline is connected. Since a vehicle may be equipped with multiple fluids, the connector matching alarm device can be used to check the matching degree of the pipeline to prevent incorrect fluid addition.

[0014] Furthermore, the fluid information request includes the type of fluid, the real-time remaining amount of fluid and the required amount of fluid to be added. By sending multiple types of information at the same time, the cloud platform can optimize the vehicle selection method based on these information requests in terms of transportation cost, transportation time, fluid loading capacity, etc., thereby greatly improving the efficiency of fluid proportioning logistics operations.

[0015] Furthermore, the vehicle-mounted terminal includes a second controller, a second signal transceiver, a second data storage device, a second sensor connected to the second liquid storage device, a fluid monitoring component and an end cover alarm device;

[0016] The second sensor and the fluid monitoring component are respectively used to monitor the liquid level information of the second liquid storage device and the real-time delivery volume of the fluid, and transmit them to the second controller. The second controller exchanges information with the cloud platform through the second signal transceiver device. The second controller is connected to the second data storage device and the end cover alarm device. The liquid level height of the fluid in the second liquid storage device can be monitored by the second sensor. When fluid is added to the first liquid storage device, since there is a certain distance between the first liquid storage device and the second liquid storage device, the second sensor can transmit the liquid level value of the fluid in the second liquid storage device to the cloud platform, which is convenient for the cloud platform to check and settle the filling amount and reduce errors during filling. The fluid monitoring component can use a flow meter or a weighing valve to cooperate with the second sensor to monitor the changes in the fluid in the second liquid storage device, thereby improving the quality and accuracy of monitoring.

[0017] Furthermore, the vehicle-mounted terminal also includes a positioning system, which is connected to the second controller via a second signal transceiver device and is used to display the current location of the vehicle. The positioning system can enable the cloud platform to accurately obtain the vehicle's location information and improve the matching accuracy.

[0018] Furthermore, the vehicle-mounted terminal also includes a fluid conveying device, which is used to provide power when the second liquid storage device adds fluid to the first liquid storage device, so as to facilitate the stable conveying of the fluid in the second liquid storage device to the first liquid storage device. Gravity conveying can also be used for fluid conveying during the fluid filling process.

[0019] Furthermore, the vehicle-mounted terminal also includes a display device connected to the second controller, which is used to display the path information between the vehicle-mounted terminal and the liquid storage terminal, the remaining fluid information of the second liquid storage device, the current location information of the vehicle, and the working status of the fluid conveying device.

[0020] The method for using the fluid proportioning logistics operation system as described above is characterized by comprising the following steps:

[0021] S1. The first liquid storage device sends a fluid information request to the cloud platform or the vehicle-mounted terminal via the liquid storage terminal through the communication network. The fluid information request includes the type of fluid, the real-time remaining amount of the fluid, and the required amount of fluid to be added;

[0022] S2. The cloud platform obtains the fluid information request and the location information of the liquid storage terminal, matches the corresponding vehicle-mounted terminal, and sends instructions to the vehicle-mounted terminal. The instructions include real-time information instructions for the fluid information request issued by the liquid storage terminal and predictive information instructions made by the cloud platform based on the fluid information of the liquid storage terminal at the set filling time; this facilitates subsequent quantitative delivery and reduces the operation and maintenance costs of fluid filling.

[0023] S3. The vehicle terminal receives instructions from the cloud platform or fluid information requests from the liquid storage terminals around the vehicle terminal, and plans a route based on the current location of the vehicle or receives a route instruction from the cloud platform to the liquid storage terminal;

[0024] S4. The vehicle drives to the liquid storage terminal, connects the second liquid storage device to the first liquid storage device through a pipeline, checks the matching degree through the connector matching alarm device, and fills the liquid after the matching is qualified;

[0025] S5. During filling, the first sensor monitors the fluid level in the first liquid storage device to obtain first liquid level data, the second sensor monitors the fluid level in the second liquid storage device to obtain second liquid level data, the fluid monitoring component monitors real-time data during fluid delivery, and the first liquid level data, the second liquid level data, and the real-time data are uploaded to the cloud platform;

[0026] S6. The cloud platform receives the first liquid level data, the second liquid level data, the real-time data, and the data information of the fluid flowing into and out of the second liquid storage device, and simultaneously receives the location information of the liquid storage terminal and the vehicle-mounted terminal, and records and stores the location information and the fluid data information. At the same time, the cloud platform transmits and verifies the data information of the fluid flowing into the vehicle, the fluid flowing out of the vehicle, the fluid data information received by the liquid storage terminal, and the fluid data information released by the liquid storage terminal in real time, and determines whether the fluid changes within the same time period are consistent. When the fluid changes are consistent, real-time settlement or periodic settlement is performed after filling. When the fluid changes are inconsistent, data abnormality is marked for the corresponding liquid storage terminal and vehicle-mounted terminal within the same time period. This can avoid fluid loss caused by human drip irrigation, and measurement errors caused by the inability of pumps and flow meters to detect information, and avoid the transmission of situations such as drivers releasing fluids on their own or stealing water in tanks. Video monitoring can also be used. After filling every day, data verification and summary are conducted, and the vehicle drives to the set location for liquid level inspection every day.

[0027] This method of use is simple in steps and can not only improve the working efficiency of the entire fluid proportioning logistics operation system, but also reduce the errors caused by manual operation, optimize the path between the vehicle and the liquid storage terminal, and effectively reduce the transportation cost of the fluid.

[0028] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0029] 1. Through the design of liquid storage terminals, cloud platforms, and vehicle-mounted terminals, not only can fluid information be quickly transmitted, but the required vehicles can also be accurately matched, and the vehicle closest to the liquid storage terminal can be selected. This also helps suppliers plan fluid delivery routes, improve the efficiency of fluid proportioning logistics operations, and reduce transportation costs.

[0030] 2. The first controller can accurately transmit the type information, remaining amount of fluid and required amount of fluid in the first liquid storage device to the cloud platform via the first signal transceiver device. The cloud platform first selects and matches the vehicle, and then selects the vehicle closest to the liquid storage terminal, thereby improving the efficiency of logistics operations and effectively avoiding the risk of fluid delivery errors.

[0031] 3. As a vehicle may be equipped with multiple fluids, the matching degree of the pipeline can be checked through the joint matching alarm device to prevent incorrect fluid addition.

[0032] 4. Through the design of the first sensor and the second sensor, the fluid levels in the first liquid storage device and the second liquid storage device can be monitored, and the respective data can be transmitted to the cloud platform, so that the cloud platform can check and settle the filling amount and reduce the error during filling.

[0033] 5. The usage method is simple and can not only improve the working efficiency of the entire fluid proportioning logistics operation system, but also reduce the errors caused by manual operation, optimize the path between the vehicle and the liquid storage terminal, improve supply efficiency, reduce operating costs, and enhance customer experience. It can be set up in various oil-using enterprises, and enterprises can consume various types of oil products according to their own needs. The oil supply and oil product monitoring data of the intelligent supply system set up by each enterprise will also be transmitted to the cloud for storage and analysis. It can not only directly reduce the logistics, storage, sales and packaging costs of metalworking fluid products for customers, but also provide customers with more accurate and high-quality services through IoT big data analysis.

[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0047] It should be noted that the terms "first," "second," and so on, in the description and claims of the present invention and the accompanying drawings are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0048] like Figure 1The figure shows a fluid proportioning logistics operation system according to the present invention, comprising a liquid storage terminal 2 for issuing fluid information requests; a cloud platform 1 for receiving the fluid information requests and location information of the liquid storage terminal 2, matching the fluid information requests and location information with a vehicle terminal 3, or calculating and predicting the fluid information of the liquid storage terminal 2 and sending instructions to the vehicle terminal 3. The fluid information includes interval filling time and filling amount; and the vehicle terminal 3 for receiving instructions from the cloud platform 1 or fluid information requests from surrounding liquid storage terminals 2, planning a route based on the vehicle's current location, or receiving route instructions sent by the cloud platform 1 to the liquid storage terminal 2. When receiving fluid information requests and location information of the liquid storage terminal 2, the cloud platform 1 can simultaneously receive one or more sets of fluid information requests and location information of the liquid storage terminal 2, thereby processing information from multiple liquid storage terminals 2 simultaneously and selecting the vehicle information that matches the corresponding liquid storage terminal 2. Simultaneously, the vehicle terminal 3 of each vehicle can send information about the type of fluid loaded and the remaining amount of fluid in the corresponding vehicle to the cloud platform 1 in real time, facilitating rapid retrieval of the vehicle and the fluid loaded by the cloud platform 1.

[0049] Through the design of the liquid storage terminal 2, the cloud platform 1 and the vehicle-mounted terminal 3, not only can the rapid transmission of fluid information be achieved, but also the required vehicle can be accurately matched, and the vehicle closest to the liquid storage terminal 2 can be selected. At the same time, it is beneficial for suppliers to plan the fluid delivery route, improve the efficiency of fluid proportioning logistics operations, and reduce transportation costs. When the cloud platform is used to obtain instructions for fluid distribution, it is convenient to quickly and accurately add fluids in more urgent situations at the liquid storage terminal. When the vehicle-mounted terminal is used to receive fluid information requests from the surrounding area, the fluid is supplemented when the liquid storage barrels of the surrounding liquid storage terminals need to be supplemented with fluid. In the actual process of adding fluid, as long as there is fluid in the liquid storage barrel of the liquid storage terminal, it will be filled up, and an assessment mechanism will be added to improve the fluid filling efficiency while reducing operation and maintenance costs.

[0050] The fluid specifically refers to metalworking fluids, including cutting fluids, cutting oils, emulsions, hydraulic oils, quenching fluids, rolling fluids, guideway oils, grinding fluids, rust removers, cleaning agents, drawing oils, lubricants, coolants, release agents, etc. The medium is primarily water, but is not limited to water and may also be other liquids.

[0051] like Figure 2As shown, the liquid storage terminal 2 specifically includes a first controller 201, a first signal transceiver 202, a first data storage device 205, and a first sensor 204 connected to the first liquid storage device 4. The first sensor 204 is connected to the first signal transceiver 202 via the first controller 201, and the first controller 201 is connected to the first data storage device 205. The first signal transceiver 202 uses a GPRS transceiver. The first sensor 204 monitors the liquid level information of the first liquid storage device 4 and transmits it to the first controller 201. The first controller 201 is used to send the liquid level information and the position information of the first liquid storage device 4 to the cloud platform 1 via the first signal transceiver 202. The first sensor 204 can be a float-type liquid level transmitter, a buoy-type liquid level transmitter, a capacitive liquid level transmitter, a magnetic flap liquid level transmitter, an ultrasonic liquid level transmitter, or a radar liquid level transmitter.

[0052] The first controller 201 can accurately transmit the type information, remaining amount of fluid and required amount of fluid in the first liquid storage device 4 to the cloud platform 1 via the first signal transceiver 202. The cloud platform 1 first selects and matches the vehicle, and then selects the vehicle closest to the liquid storage terminal 2, thereby improving the efficiency of logistics operations and effectively avoiding the risk of fluid delivery errors. The first data storage device 205 is used to store real-time filling data information to avoid the inability to upload data due to signal interruption.

[0053] The first liquid storage device 4 is connected to a connector matching alarm device 203, which is used to check the matching degree when the pipeline is connected. Since the vehicle may be equipped with multiple fluids, the connector matching alarm device 203 can be used to check the matching degree of the pipeline to prevent incorrect fluid addition. The matching degree can be achieved by scanning a QR code, matching the pipeline interface structure, etc.

[0054] When the pipeline is connected by QR code scanning, the first liquid storage device 4 and the pipeline connected to the second liquid storage device 5 of the vehicle are scanned respectively through a smart mobile terminal such as a mobile phone or IPAD. When the two QR codes are consistent, it means that the fluids in the first liquid storage device 4 and the second liquid storage device 5 are the same fluid, and filling can be carried out. When the two QR codes are inconsistent, filling cannot be carried out.

[0055] When using the pipeline interface structure matching method to connect the pipeline, such as Figure 5 As shown, the vehicle-mounted delivery connector connected to the vehicle's second liquid storage device 5 can be inserted into the liquid storage device connector of the first liquid storage device 4 to be filled, and the vehicle's display device 304 is used to determine whether the connectors match. If not, the vehicle-mounted delivery connector is replaced. If so, fluid is added. During the addition process, it is determined whether the fluid filling amount reaches a set threshold, which can be the maximum value of the first sensor or the minimum value of the second sensor. After reaching the set threshold, fluid filling is stopped.

[0056] The fluid information request includes the type of fluid, the real-time remaining amount of the fluid and the required amount of fluid to be added. By sending multiple information at the same time, the cloud platform 1 can optimize the selection of vehicles based on these information requests in terms of transportation cost, transportation time, fluid loading volume, etc., thereby greatly improving the efficiency of fluid proportioning logistics operations.

[0057] like Figure 3 As shown, the vehicle-mounted terminal 3 specifically includes a second controller 301, a second signal transceiver 302, a second data storage 307, a second sensor 305 connected to the second liquid storage device 5, a fluid monitoring component 308, and an end cap alarm device 309. The second signal transceiver 302 uses a GPRS transceiver. The second sensor 305 and the fluid monitoring component 308 are used to monitor the liquid level information and the real-time fluid delivery volume of the second liquid storage device 5, respectively, and transmit them to the second controller 301. The second controller 301 exchanges information with the cloud platform 1 through the second signal transceiver 302. The second controller 301 is connected to the second data storage 307 and the end cap alarm device 309. The second sensor 305 can be a float-type liquid level transmitter, a buoy-type liquid level transmitter, a capacitive liquid level transmitter, a magnetic flap liquid level transmitter, an ultrasonic liquid level transmitter, or a radar liquid level transmitter. The fluid monitoring component 308 can use a flow meter or a weighing valve to cooperate with the second sensor to monitor the fluid changes in the second liquid storage device to improve the quality and accuracy of monitoring.

[0058] The second sensor 305 can be used to monitor the liquid level of the fluid in the second liquid storage device 5. When fluid is added to the first liquid storage device 4, since there is a certain distance between the first liquid storage device 4 and the second liquid storage device 5, the second sensor 305 can transmit the liquid level value of the fluid in the second liquid storage device 5 to the cloud platform 1, so that the cloud platform 1 can check and settle the filling amount and reduce errors during filling.

[0059] The vehicle-mounted terminal 3 also includes a positioning system 303, which is connected to the second controller 301 via the second signal transceiver 302 and is used to display the current location of the vehicle. The positioning system 303 enables the cloud platform 1 to accurately obtain the vehicle's location information, improving the accuracy of the matching. The positioning system 303 uses the GPS positioning system 303, the Galileo positioning system 303, or the Beidou positioning system 303 to obtain the real-time location of the vehicle.

[0060] The vehicle-mounted terminal 3 also includes a fluid conveying device 306, which is used to provide power when the second liquid storage device 5 adds fluid to the first liquid storage device 4, so as to facilitate the stable delivery of the fluid in the second liquid storage device 5 to the first liquid storage device 4. Gravity conveying can also be used for fluid delivery during the fluid filling process.

[0061] The vehicle-mounted terminal 3 also includes a display device 304 connected to the second controller 301. The display device 304 is used to display information about the path between the vehicle-mounted terminal 3 and the liquid storage terminal 2, information about the remaining fluid in the second liquid storage device 5, the vehicle's current location, and the operating status of the fluid delivery device 306. The display device 304 is a monitor connected to the second controller 301, the second sensor 305, and the fluid delivery device 306 via a CAN bus, allowing the display to display corresponding data information in real time.

[0062] For example, a method of using the fluid proportioning logistics operation system as described above, Figure 4 As shown, the following steps are included:

[0063] S1, the first liquid storage device 4 sends a fluid information request to the cloud platform 1 or the vehicle-mounted terminal 3 through the liquid storage terminal 2 through the communication network. The fluid information request includes the type of fluid, the real-time remaining amount of the fluid and the required amount of fluid to be added; when issuing the fluid information request, the fluid level in the first liquid storage device needs to reach the threshold of the first sensor to trigger the first sensor to send a liquid level signal to the first controller of the liquid storage terminal, and the first controller sends the fluid information request to the cloud platform.

[0064] S2. Cloud platform 1 obtains the fluid information request and the location information of the liquid storage terminal 2, matches it with the corresponding onboard terminal 3, and sends a command to the onboard terminal 3. The command includes a real-time information command for the liquid storage terminal to issue the fluid information request and a predictive information command based on the cloud platform's statistics of the fluid information at the liquid storage terminal's set filling time. This facilitates subsequent quantitative delivery and reduces the operational and maintenance costs of fluid filling. After the first signal transceiver sends the fluid information request to the cloud platform, the cloud platform also obtains the location information of the liquid storage terminal. At the same time, the onboard terminal of each vehicle sends information such as the type of fluid in the second liquid storage device and the remaining fluid amount to the cloud platform in real time, allowing the cloud platform to quickly match vehicles based on the fluid information request, thereby improving the efficiency of the entire fluid proportioning logistics operation system.

[0065] S3, the vehicle-mounted terminal 3 receives the instructions sent by the cloud platform 1 or the fluid information request sent by the liquid storage terminal 2 around the vehicle-mounted terminal 3, and plans the path according to the current position of the vehicle or receives the path instructions sent by the cloud platform to the liquid storage terminal; when the vehicle-mounted terminal receives the instructions sent by the cloud platform, the current position of the vehicle is extracted through the positioning system of the vehicle-mounted terminal, and the optimized path is selected through the system.

[0066] S4. The vehicle drives to the liquid storage terminal 2, connects the second liquid storage device 5 to the first liquid storage device 4 through a pipeline, checks the matching degree through the connector matching alarm device 203, and adds fluid after the matching is qualified; since the vehicle may be equipped with multiple fluids, the matching degree of the pipeline can be checked through the connector matching alarm device 203 to prevent fluid addition errors.

[0067] S5. During filling, the first sensor 204 monitors the fluid level in the first liquid storage device 4 to obtain first liquid level data, the second sensor 305 monitors the fluid level in the second liquid storage device 5 to obtain second liquid level data, and the fluid monitoring component 308 monitors real-time data during fluid delivery. The first liquid level data, the second liquid level data, and the real-time data are uploaded to the cloud platform 1;

[0068] S6. The cloud platform receives the first liquid level data, the second liquid level data, the real-time data, and the data information of the fluid flowing into and out of the second liquid storage device, and simultaneously receives the location information of the liquid storage terminal and the vehicle-mounted terminal, and records and stores the location information and the fluid data information. At the same time, the cloud platform transmits and verifies the data information of the fluid flowing into the vehicle, the fluid flowing out of the vehicle, the fluid data information received by the liquid storage terminal, and the fluid data information released by the liquid storage terminal in real time, and determines whether the fluid changes within the same time period are consistent. When the fluid changes are consistent, real-time settlement or periodic settlement is performed after filling. When the fluid changes are inconsistent, data abnormality is marked for the corresponding liquid storage terminal and vehicle-mounted terminal within the same time period. This can avoid fluid loss caused by human drip irrigation, and measurement errors caused by the inability of pumps and flow meters to detect information, and avoid the transmission of situations such as drivers releasing fluids on their own or stealing water in tanks. Video monitoring can also be used. After filling every day, data verification and summary are conducted, and the vehicle drives to the set location for liquid level inspection every day. The cloud platform can store the first liquid level data and the second liquid level data, as well as the location information of the liquid storage terminal and the vehicle terminal corresponding to the corresponding data information, so that management personnel can retrieve historical data through the background for verification. When data anomalies occur, judgments can be made based on information such as time, location, and filling volume, greatly improving the fluid transportation efficiency and management efficiency.

[0069] The method of use is simple in steps and can not only improve the working efficiency of the entire fluid proportioning logistics operation system, but also reduce the errors caused by manual operation, optimize the path between the vehicle and the liquid storage terminal 2, improve supply efficiency, reduce operating costs, and enhance customer experience. It can be set up in various oil-using enterprises, and enterprises can consume various types of oil products according to their own needs. The oil supply and oil product monitoring data of the intelligent supply system set up by each enterprise will also be transmitted to the cloud for storage and analysis. It can not only directly reduce the logistics, storage, sales and packaging costs of metalworking fluid products for customers, but also provide customers with more accurate and high-quality services through Internet of Things big data analysis.

[0070] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications based on the present invention to achieve substantially the same technical effects are all within the scope of protection of the present invention.
