Description

Technical Field

[0001] This utility model belongs to the field of fuel control for fuel stoves, and in particular relates to a fuel control system for fuel stoves. Background Technology

[0002] In recent years, fuel stoves have been widely used in the catering industry. A large proportion of these establishments operate on a model where suppliers provide fuel for the stoves free of charge. The advantage of this is that catering establishments do not need to invest in purchasing equipment; they only need to buy fuel from the supplier. This should have been a win-win situation. However, due to a lack of control over the source of fuel for catering establishments, some establishments have illegally used fuel from unknown sources, resulting in equipment damage and seriously harming the economic interests of suppliers.

[0003] Therefore, we need to design a fuel control system for oil stoves to solve these problems. Utility Model Content

[0004] The problem this invention aims to solve is to provide a fuel control system for a fuel stove. This fuel control system can monitor the fuel consumption and replenishment status of the fuel stove in real time and provide the supplier with the operating parameters and working status of the entire system.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A fuel control system for an oil stove includes a storage device, a control unit, and a control terminal;

[0007] The storage device is used to store fuel, and its output is connected to the input of the combustion device.

[0008] The input terminal of the control unit is connected to the storage device and the combustion device respectively, and is used to collect fuel storage information in the storage device and fuel usage information of the combustion device;

[0009] The control terminal is connected to the control unit and is used to acquire information collected by the control unit and to adjust and interact with the control unit based on its operating status.

[0010] Preferably, the control system further includes a data server, and the control unit and the control terminal are connected through the data server.

[0011] This setup utilizes a data server to create a data transfer and processing hub between the control unit and the control terminal. On one hand, it alleviates the storage and computational pressure on the control unit, eliminating the need for long-term storage of massive amounts of fuel data. Data can be uploaded to the server in real time, avoiding operational lag caused by local storage overload. On the other hand, if the system covers multiple fuel stove areas, the server can aggregate and analyze data from multiple control units to generate a global fuel usage report, allowing the control terminal to grasp fuel consumption trends from a macro perspective. Furthermore, the server also serves as a data backup; even if a control unit malfunctions, uploaded data will not be lost, ensuring the security and continuity of fuel management data.

[0012] Preferably, the control unit includes a processing module and a status indication module, a data storage module, a power supply module, a wired communication module, and a wireless communication module connected to the processing module;

[0013] The processing module is used to process the collected data information.

[0014] The status indication module is used to indicate the operating status of the control unit;

[0015] The data storage module has a power-off storage function, which is used to store the collected data information and the data information processed by the processing module;

[0016] The power module has an AC-DC conversion function and is used to power the processing module;

[0017] The wired communication module is connected to the combustion device; the wireless communication module is connected to the data server.

[0018] This multi-module design enables the control unit to feature multifunctional integration, reliable operation, and flexible communication. The processing module, as the core, can quickly process stored data and combustion device usage data, providing accurate data for control terminal adjustments. The status indicator module uses LED indicators to visually reflect whether the control unit is operating normally in power supply, communication, and other functions, facilitating quick troubleshooting and reducing maintenance costs. The data storage module with power-off storage function can save critical data during sudden power outages, preventing management disruptions due to data loss. The AC-DC power conversion module is adaptable to different power supply environments, providing a stable voltage to the control unit and preventing voltage fluctuations from affecting operation. The combination of wired and wireless communication modules ensures stable data transmission with the combustion device while enabling flexible communication with the data server, balancing data transmission reliability and environmental adaptability.

[0019] Preferably, a monitoring device is provided on the storage device, the output of which is connected to the input of the control unit, and the monitoring device is a float-type oil level sensor.

[0020] This setup enables real-time and precise monitoring of fuel levels. The float-type sensor uses a float that rises and falls with the fuel level to drive mechanical or electronic components to output signals. Adapting to the liquid characteristics of fuel, it directly reflects the fuel level in the storage device, thereby calculating the accurate fuel level. This avoids the problems of large errors, low efficiency, and poor safety associated with traditional manual measurements. Simultaneously, the sensor transmits the fuel level data to the control unit in real time, allowing managers to remotely monitor the remaining fuel level through a control terminal without on-site inspections. This not only enables timely detection of fuel leaks but also allows for advance planning of refueling times, preventing the stove from shutting off due to insufficient fuel and ensuring the continuous and stable operation of the stove.

[0021] Preferably, the combustion device includes a plurality of fuel stoves, the storage device is connected to the plurality of fuel stoves respectively through a delivery pipeline, and each fuel stove is equipped with a flow meter, and the wired communication module on the control unit is connected to the flow meter on the fuel stove through a data bus.

[0022] This setup, with a separate flow meter for each fuel stove, accurately tracks the real-time and cumulative fuel consumption of each stove, enabling individual metering and centralized management. The control unit connects to all flow meters via a data bus, significantly reducing wiring and installation costs. Simultaneously, bus communication allows for the synchronous acquisition of data from multiple flow meters, improving data transmission efficiency. Furthermore, based on the consumption data from individual fuel stoves, managers can analyze energy consumption differences across devices via the control terminal, identify high-energy-consuming equipment, and implement adjustments, providing data support for energy conservation and emission reduction.

[0023] Preferably, the data server communicates with the wireless communication module and the control terminal via 4G / 5G wireless communication.

[0024] This setup, employing 4G / 5G wireless communication technology, enhances the system's remote management capabilities and data transmission efficiency. It also boasts a wide control range, ensuring stable communication and real-time monitoring of operations even when the data server, control unit, and control terminal are located in different areas. Furthermore, the high transmission rate of 4G / 5G networks enables rapid transmission of real-time fuel data, preventing management delays caused by data latency. In addition, the strong anti-interference capabilities of 4G / 5G networks reduce data transmission packet loss even in environments with high interference, ensuring accurate issuance of fuel management commands and complete data upload.

[0025] Preferably, the control terminal is a mobile APP.

[0026] This setup, by making the control terminal a mobile app, makes fuel management more mobile, convenient, and real-time. On one hand, the mobile app eliminates the need for additional dedicated equipment; managers can log in anytime, anywhere using their mobile phones to check fuel levels, consumption, and equipment operating status, without needing to be stationed in a monitoring room, thus improving management flexibility. On the other hand, the mobile app can push real-time alerts, allowing managers to receive warnings immediately and take action, shortening fault response time. Furthermore, it is easy for non-professionals to quickly learn and use, lowering the barrier to entry and making it suitable for the operational needs of managers in different positions.

[0027] The advantages and positive effects of this utility model are:

[0028] This invention achieves a closed-loop fuel management process through a three-layer architecture. The storage device, as the fuel supply source, is directly connected to the combustion unit, ensuring a simple and stable fuel delivery path and reducing losses or failure points in intermediate stages. The control unit is connected to both the storage device and the combustion unit, enabling simultaneous collection of bidirectional data on fuel storage and consumption. This avoids management blind spots caused by single data collection, such as knowing only the storage level but not the consumption level, or knowing only the consumption level but not matching the storage level. The control terminal is linked with the control unit, allowing managers to obtain real-time dynamic information on fuel storage and consumption, and remotely adjust the control unit's operating status and interact with it. This breaks the time and space limitations of traditional manual inspections and on-site operations, significantly improving management efficiency and response speed. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings:

[0037] Example 1: As Figures 1-2 As shown, a fuel control system for a fuel stove includes a storage device, a control unit 2, and a control terminal 4.

[0038] The storage device is used to store fuel, and its output end is connected to the input end of the combustion device 7 to provide a continuous fuel supply to the combustion device 7, forming the basic fuel supply link of the system.

[0039] The input terminals of the control unit 2 are connected to the storage device and the combustion device 7 respectively. Its core function is to establish a data interaction channel between the storage device and the combustion device 7. Through this channel, fuel storage information in the storage device and fuel usage information of the combustion device 7 are collected in real time, such as instantaneous consumption and cumulative consumption, so as to realize the synchronous collection of key data on fuel storage and usage.

[0040] Control terminal 4 is connected to control unit 2. Control unit 2 initially integrates the collected storage and usage data and transmits it to control terminal 4. Control terminal 4 generates operating status feedback based on the received data. At the same time, the management personnel issue adjustment commands through control terminal 4. After the commands are parsed by control unit 2, they are applied to storage device or combustion device 7, forming a closed-loop linkage from data acquisition to command issuance and then to execution feedback.

[0041] The control system also includes a data server 3, and the control unit 2 and control terminal 4 are connected through the data server 3;

[0042] Data server 3 acts as a relay hub between control unit 2 and control terminal 4, handling bidirectional data transmission between the two: the data collected, stored, and used by control unit 2 is first uploaded to data server 3, where it is classified, stored, format-converted, and preliminarily verified before being forwarded to control terminal 4. This avoids transmission anomalies caused by data format mismatch when control terminal 4 interacts directly with control unit 2. Simultaneously, adjustment commands issued by control terminal 4 are first transmitted to data server 3. After verifying the legality of the commands, the server forwards valid commands to control unit 2 for execution. Through the relay processing of the server, the stability and security of data interaction between control unit 2 and control terminal 4 are improved, forming a hierarchical linkage transmission architecture from control unit 2 to data server 3 and then to control terminal 4.

[0043] The control unit 2 includes a processing module 23 and a status indication module 21, a data storage module 22, a power supply module 24, a wired communication module 25, and a wireless communication module 26 connected to the processing module 23;

[0044] The processing module 23 is used to process the collected data information. As the core computing power component of the control unit 2, it receives various types of data transmitted by the wired communication module 25 and the wireless communication module 26, and performs data calculation, logical judgment and other processing operations. At the same time, the control commands generated by the processing module 23 are also sent through the communication module to realize the linkage between data processing and command output.

[0045] The status indicator module 21 is used to indicate the operating status of the control unit 2. It is linked with the processing module 23 in real time. The processing module 23 transmits its own and the operating status data of each associated module to the status indicator module 21, such as power supply voltage, communication connection status, etc. The status indicator module 21 presents them in a visual way, which makes it easy to quickly locate the abnormal points of operation.

[0046] The data storage module 22 has a power-off storage function, which is used to store the collected data information and the data information processed by the processing module 23. It works synchronously with the processing module 23. The processing module 23 writes real-time data into the data storage module 22. It retains key data in the event of a sudden power outage. After the power is restored, the processing module 23 can retrieve historical data from the data storage module 22 to continue the operation, ensuring data continuity.

[0047] The power module 24 has an AC-DC conversion function to power the processing module 23. It is directly electrically connected to the processing module 23, converting external AC power into DC power that is compatible with the processing module 23. At the same time, it provides a stable power supply for other related modules such as the status indicator module 21 and the data storage module 22, ensuring that each module and the processing module 23 operate in coordination.

[0048] The wired communication module 25 is connected to the combustion device 7 and is used to receive fuel usage data from the combustion device 7 and transmit it to the processing module 23; the wireless communication module 26 is connected to the data server 3 and is used to upload the data processed by the processing module 23 to the data server 3 and receive the control terminal 4 instructions forwarded by the data server 3. The two communication modules undertake different data transmission tasks respectively, forming a linkage architecture of "dual communication channel - core processing" with the processing module 23.

[0049] A monitoring device 5 is installed on the storage device. The output end of the monitoring device 5 is connected to the input end of the control unit 2. The monitoring device 5 is a float-type oil level sensor.

[0050] The float-type fuel level sensor is directly installed inside the storage device. Its detection end generates a corresponding electrical signal as the fuel level changes. This electrical signal serves as the fuel storage information of the storage device and is directly transmitted to the input end of the control unit 2 through the output end, forming a "real-time detection-data transmission" linkage with the control unit 2. After receiving the sensor signal, the control unit 2 can calculate the actual fuel level by combining it with the volume parameters of the storage device. This provides data support for subsequent judgments on whether fuel needs to be replenished, whether there are leaks, or other abnormalities, realizing direct linkage between storage device status monitoring and control unit 2 data processing.

[0051] The combustion device 7 includes several fuel stoves. The storage device is connected to several fuel stoves through the delivery pipeline 6. Each fuel stove is equipped with a flow meter. The wired communication module 25 on the control unit 2 is connected to the flow meter on the fuel stove through the data bus 8.

[0052] The storage device distributes fuel to each fuel stove through the delivery pipeline 6, forming a fuel supply link with one source and multiple ends. The flow meter of each fuel stove collects the amount of fuel passing through the stove in real time, i.e., fuel usage information. Each flow meter is connected in parallel to the wired communication module 25 of the control unit 2 through the data bus 8, forming a centralized data acquisition link. The wired communication module 25 summarizes the usage data of each flow meter and transmits it to the processing module 23. The processing module 23 combines the stored data of the storage device to calculate the fuel consumption rate of a single fuel stove and the whole system, realizing the linkage between the separate metering of the combustion device 7 and the centralized processing of the control unit 2.

[0053] Data bus 8 is a 485 data bus, which transmits real-time fuel consumption (ml / min) to control unit 2. Control unit 2 calculates the total fuel consumption per minute by summing the real-time fuel consumption of all subordinate fuel stoves through processing module 23, and then calculates the cumulative fuel consumption of all fuel stoves according to the running time of the fuel stoves. The cumulative fuel consumption is uploaded to data server 3 every 10 minutes. To prevent errors in fuel measurement caused by unexpected power outages or network outages, data storage module 22 has the function of saving data when power is off. When an abnormal power outage occurs, the data is automatically saved. After the power is restored, the saved data is read and uploaded to data server 3 to ensure the accuracy of fuel measurement.

[0054] The data server 3 communicates wirelessly with the wireless communication module 26 and the control terminal 4 via 4G / 5G. The wireless communication module 26 of the control unit 2 establishes a wireless connection with the data server 3 through the 4G / 5G network. The data processed by the processing module 23 and stored and used is encrypted by the wireless communication module 26 and then transmitted to the data server 3. After receiving the data, the data server 3 forwards the data to the control terminal 4 through the same 4G / 5G network. At the same time, the adjustment instructions generated by the control terminal 4 are transmitted to the data server 3 through the 4G / 5G network, and then forwarded by the data server 3 to the wireless communication module 26, and finally transmitted to the processing module 23 for execution. The high bandwidth and low latency of the 4G / 5G network ensure the real-time transmission of long-distance data between the control unit 2, the data server 3, and the control terminal 4, and realize cross-regional wireless linkage.

[0055] Control terminal 4 is a mobile APP. As control terminal 4, the mobile APP obtains various data uploaded by control unit 2 through wireless communication with data server 3. Managers can view information such as storage device inventory and consumption of each burner in the combustion device 7 in real time through the mobile APP interface. When it is necessary to adjust the system operation status, the manager generates adjustment commands on the mobile APP. The commands are transmitted to control unit 2 after being relayed through data server 3. After the control unit 2 executes the commands, it feeds back the execution results to the mobile APP, realizing remote control and status monitoring of the system by the manager through the mobile terminal, improving the convenience of operation.

[0056] When the float-type fuel level sensor detects that the fuel level in the storage device 1 is lower than the safety value, it notifies the fuel supplier to replenish the fuel in time via the mobile APP. After the fuel tank is filled with fuel, the operator uses the mobile APP to set the precise amount of fuel added and clicks the reset button. This operation command is transmitted to the data server 3 via the mobile APP, and then sent to the control unit 2 via the data server 3. The control unit 2 clears the cumulative fuel consumption.

[0057] When illegal refueling occurs, the float-type fuel level sensor detects an increase in fuel level but does not receive a reset command from the mobile app. This is considered illegal refueling, and the supplier will be notified via the mobile app or SMS. In addition, the supplier can compare the previous fuel level with the total fuel consumed by all fuel stoves. If the consumption is significantly higher than the sales volume, it can be determined that the catering establishment has engaged in illegal refueling.

[0058] The control system of this application can also provide remote upgrade function to upgrade and maintain the firmware of control unit 2 and fuel stove. The working parameters of fuel stove can be remotely set through mobile APP to adapt to more usage scenarios and optimize fuel thermal efficiency. The working parameters include, but are not limited to: air volume and fuel volume at each level, default start-up level, ignition duration, delayed fuel pumping time, rotary knob for supplementary ignition, joystick shifting, external start / stop switch mode, etc.

[0059] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
