Description

Technical Field

[0001] The present invention relates to the technical field of refueling equipment, and in particular to an electronic intelligent refueling gun. Background Art

[0002] With the rapid development of the economy and society, the level of intelligence is getting higher and higher. As a window for sales companies to the society, gas stations need to strengthen intelligent construction and improve risk management. In recent years, with the implementation of online monitoring systems at gas stations, gas stations have achieved significant results in environmental protection control, and have realized fault alarms in aspects such as refueling status monitoring, increasing a certain level of safety.

[0003] The refueling system mainly includes the refueling machine, oil pipe, refueling gun, etc. The data obtained by the online monitoring system of the gas station comes from the feedback of the refueling machine, and cannot directly obtain the real-time operation data of the refueling gun. The traditional refueling gun is mechanical and uses the Venturi effect to control the start of the oil gun. After the traditional oil gun has been running for a long time, the wear of the mechanical components will cause the oil and gas to operate in abnormal conditions, which may further cause more serious safety accidents. Therefore, at present, gas stations generally replace traditional mechanical refueling guns regularly, but abnormal conditions are still inevitable.

[0004] For the status detection of the fuel gun, the existing technology adds a monitoring module to the traditional fuel gun, but the mechanical structure of the fuel gun is complex and compact. After the monitoring module is installed, the fuel gun becomes bulky, which is not conducive to the operation of the refueling staff on the one hand, and on the other hand, it is difficult to adapt to the fuel dispenser after the size increases.

DETAILED DESCRIPTION

[0053] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0054] The prior art (CN113307218A) provides an intelligent refueling gun, which is used in conjunction with a refueling machine and includes: a driving unit, a sensing unit, a timing unit, a communication unit, and a control unit; the control unit controls the working states of the driving unit, the sensing unit, the timing unit, and the communication unit; the driving unit controls the oil output speed and / or the oil output amount based on the control of the control unit; the sensing unit senses the use environment of the refueling gun for detection and transmits the sensing result to the control unit; the timing unit times the refueling process and / or the completion of refueling of the refueling gun, and transmits the timing result to the control unit; the communication unit communicates with an external terminal through a server based on the control of the control unit. The intelligent refueling gun of the present invention has a simple structure, can effectively warn of potential safety hazards, is convenient for eliminating potential safety hazards, and makes countermeasures; in addition, remote management can be realized, which is convenient for popularization and use.

[0055] However, the above-mentioned prior art does not clearly define the specific structure of the gun body and how to implement it, nor does it mention or solve practical problems such as the implementation of the refueling gun jumping structure.

[0056] The prior art (CN102020229B) provides a wireless electronic fuel tank lock, a wireless electronic refueling gun and a matching refueling system. The wireless electronic fuel tank lock and the wireless electronic refueling gun are designed using ZigBee technology, WSN technology and embedded system technology. The wireless electronic fuel tank lock used is installed on the fuel tank cover of the vehicle fuel tank. The wireless electronic refueling gun is used on the refueling machine at the existing gas station. A certain number of RFD / FFD nodes are formed with each vehicle and wireless electronic refueling gun as a unit. A guide node is installed at the entrance of the gas station where the electronic refueling gun is installed. A navigation node is installed in the parking lot where the vehicle is equipped with a wireless electronic fuel tank lock. A wireless sensor network is formed with RFD / FFD nodes, navigation nodes, guide nodes and a main controller. The main controller receives RFD / FFD node data, and realizes real-time monitoring and control of the system FFD / RFD nodes according to the instructions issued by the upper computer monitoring platform, thereby realizing remote control of vehicle electronic identity recognition and fuel refueling.

[0057] However, the above-mentioned prior art does not mention the intelligence of the refueling gun, that is, the jumping gun method and related logic of the refueling gun, nor does it mention the self-sealing structure of the refueling gun's elevation angle and the logic of its implementation.

[0058] The prior art (CN218261970U) provides a state-transmittable refueling gun, which includes: a refueling gun body, which is a vehicle-mounted oil and gas recovery system compatible oil and gas recovery refueling gun structure; a position sensing unit, which is used to measure the working state information of the induction valve in the refueling gun body; a state transmission unit, which has wireless transmission capability, and is used to transmit the working state information of the induction valve to the oil and gas recovery online monitoring system in the gas station to determine whether the current refueling vehicle has a vehicle-mounted oil and gas recovery system. The utility model can measure the state of the gas collecting hood and the identification state of the vehicle-mounted oil and gas recovery system during the refueling process. And it can also be transmitted to the oil and gas recovery online monitoring system in the gas station in a timely manner, so that the working state of the vehicle-mounted oil and gas recovery system compatible oil and gas recovery refueling gun can be diagnosed and analyzed, so that the oil and gas recovery online monitoring system has an intelligent diagnosis function for the vehicle-mounted oil and gas recovery system compatible oil and gas recovery refueling gun.

[0059] However, the above-mentioned prior art has made improvements on the basis of the original mechanical refueling gun, and has not proposed an electronic intelligent refueling gun.

[0060] Traditional mechanical refueling guns are commonly used equipment for refueling at gas stations. They only have the function of refueling and do not have the function of detecting the refueling status. In addition, due to their size and mechanical structure, it is difficult to install status monitoring and transmission systems.

[0061] In summary, in order to solve the problems of the current prior art, the present invention provides an electronic intelligent refueling gun that can effectively monitor and transmit the refueling status, and use an electronic structure to effectively control the refueling process, thereby increasing the safety during the refueling process.

[0062] Figure 1 A schematic structural diagram of an electronic intelligent refueling gun according to an embodiment of the present invention is shown.

[0063] An electronic intelligent refueling gun includes: a state detection module, a refueling control module and a control module 11. The state detection module is used to detect the posture of the refueling gun in real time to generate a posture sensing result, and perform anti-drip oil control according to the posture control instruction. The refueling control module is used to detect the liquid level injected into the container during the refueling process to generate a liquid level detection result, and perform refueling control according to the refueling control instruction. The control module 11 generates a posture control instruction based on the posture sensing result, and generates a refueling control instruction based on the liquid level detection result.

[0064] It should be noted that, in order to adapt to existing fuel dispensers and vehicles, the overall shape of the electronic intelligent fueling gun provided by the present invention is similar to that of the existing traditional mechanical fueling gun (for example, it has a fueling gun butt 15, etc.), but the present invention makes intelligent improvements on the basis of the traditional mechanical fueling gun. Furthermore, the fueling gun body mentioned in the present invention is the fueling gun body of the traditional mechanical fueling gun after removing the mechanical structure related to the jump gun.

[0065] In one embodiment, Figure 1 As shown, the state detection module includes: a posture sensing unit 9, which is arranged on the fueling gun body and is used to sense the angle between the extension direction of the fueling gun barrel 1 and the horizontal plane in real time to generate a posture sensing result.

[0066] Compared with the traditional mechanical fueling gun, the present invention adds a posture sensing unit 9 to determine the parameters such as the tilt angle of the fueling gun and give a corresponding alarm, thereby effectively reducing the occurrence of safety accidents.

[0067] In one embodiment, Figure 1 As shown, the status detection module includes: an anti-drip unit 5, which is arranged in the refueling pipeline and is used to open or close according to the posture control instruction, wherein when the anti-drip unit 5 is turned on, the refueling gun has the anti-drip capability, and when the anti-drip unit 5 is closed, the refueling gun does not have the anti-drip capability.

[0068] Specifically, Figure 3 It is a cross-sectional view of the anti-drip oil unit 5, which includes: a self-plugging head 6 and an annular anti-drip oil electromagnetic structure 7, wherein the self-plugging head 6 is a T-shaped structure, which is arranged on the refueling pipeline, and when the annular anti-drip oil electromagnetic structure 7 is adsorbed on or away from the self-plugging head 6, the anti-drip oil unit 5 is in an open or closed state.

[0069] Furthermore, the anti-drip unit 5 adopts the design mode of the electromagnetic valve, and determines whether the anti-drip unit 5 is turned on through the data fed back by the attitude sensing unit 9. Specifically, the attitude sensing unit 9 first determines whether the fuel gun is in an upright state, otherwise the communication tanker alarms and displays "the fuel gun is in an abnormal state"; then it determines the angle between the extension direction of the fuel gun nozzle and the horizontal plane, and the angle is greater than the preset angle (for example, 30°), the anti-drip unit 5 is turned on, otherwise the anti-drip unit 5 is closed, effectively preventing oil dripping. Through the induction of the attitude sensing unit 9, the prevention of oil dripping is more accurate, and it is effectively determined whether the fuel gun is in a working state to ensure the safety of the fueling system.

[0070] In one embodiment, Figure 1 As shown, the refueling control module includes: a liquid level detection unit 2, which is arranged at the refueling gun barrel 1, and is used to detect whether the liquid level injected into the container (such as a vehicle tank, a container to be refueled) contacts the liquid level detection unit 2 in the refueling state to generate a liquid level detection result.

[0071] Specifically, if Figure 2 As shown, the liquid level detection unit 2 includes one or two liquid level sensors arranged on the outer wall of the refueling gun barrel, wherein the liquid level sensor adopts a photoelectric liquid level sensor or a radar sensor.

[0072] Conventional refueling guns in the prior art use the Venturi effect to detect the refueling liquid level, but the gun often jumps prematurely. To solve this problem, the electronic intelligent refueling gun provided by the present invention uses a liquid level sensor for detection. When the liquid level detection unit 2 uses a photoelectric liquid level sensor, the photoelectric liquid level sensor is a certain value (for example, a) in the air and another value (for example, b) in gasoline (or diesel). When the liquid level is submerged in the photoelectric liquid level sensor, the transmission signal will have a sudden change (for example, from a to b), thereby realizing refueling liquid level monitoring. Furthermore, the liquid level detection unit 2 can also use a radar liquid level sensor.

[0073] In one embodiment, Figure 2 As shown, the liquid level detection unit 2 includes a liquid level sensor disposed on the outer wall of the fueling gun barrel, for example, only includes the first liquid level sensor 3 or the second liquid level sensor 4. Specifically, the liquid level detection unit 2 uses a single photoelectric liquid level sensor, and the signal value of the sensor in the air is measured as a, and then the signal value of the sensor in 92 gasoline is measured as b. The value b is significantly different from the value a, so it is determined that when the signal value suddenly changes, it is considered that the liquid level is detected.

[0074] Furthermore, in order to prevent a single liquid level sensor from malfunctioning and causing a safety accident, such as Figure 2 As shown, the liquid level detection unit 2 includes two liquid level sensors arranged on the outer wall of the nozzle of the refueling gun, for example, including a first liquid level sensor 3 and a second liquid level sensor 4. In the control logic, a double sensor judgment is added. When both liquid level sensors detect the liquid level, it is determined that the injected container is full of gasoline (or diesel). If only one of the two liquid level sensors detects a signal transition, and the other liquid level sensor does not detect a signal transition, it is considered that the refueling gun is abnormal.

[0075] In one embodiment, the liquid level detection unit 2 uses a photoelectric liquid level sensor and a radar sensor. The photoelectric sensor determines the signal value of the sensor in the air as a, and then determines the signal value of the sensor in 92 gasoline as b. The value b is significantly different from the value a, so it is determined that when the signal value suddenly changes, the liquid level is detected. In order to prevent the liquid level sensor from malfunctioning, a radar sensor is used for auxiliary measurement. The radar sensor determines the liquid level distance as m, and corrects the sensor parameters. It is believed that when the photoelectric liquid level sensor responds, m is zero. The present invention adds a dual sensor judgment. When both sensors detect the liquid level, it is determined that the fuel tank is full. If one of the two sensors detects a signal transition and the other does not, it is considered that the fuel gun is abnormal.

[0076] In one embodiment, the refueling control module includes: a refueling controller, which is arranged in the refueling pipeline and is used to open or close according to the refueling control instruction, wherein when the refueling controller is turned on, the refueling pipeline is opened, and when the refueling controller is turned off, the refueling pipeline is closed.

[0077] Specifically, if Figure 1 As shown, the refueling controller includes: a refueling electromagnetic structure 13 and a sealing plug 14, wherein the refueling electromagnetic structure 13 is arranged on the outside of the refueling pipeline, and when the sealing plug 14 is adsorbed on or away from the refueling electromagnetic structure 13, the refueling controller is in an open or closed state.

[0078] Different from the complicated jump-off gun structure of the conventional refueling gun in the prior art, the present invention adopts electromagnetic jump-off control. When the sealing plug 14 is adsorbed on the refueling electromagnetic structure 13, the refueling controller is in the open state, and the oil can flow along the refueling pipeline from the refueling pipeline inlet 16 to the anti-drip unit 5. If the anti-drip unit 5 is in the closed state, the oil can continue to flow to the refueling gun barrel 1, and the refueling gun can refuel the injected container. When the sealing plug 14 is away from the refueling electromagnetic mechanism 13, the refueling controller is in the closed state, and the oil cannot flow along the refueling pipeline from the refueling pipeline inlet 16 to the anti-drip unit 5, and the refueling gun cannot refuel the injected container.

[0079] In one embodiment, the control module 11 includes: a state judgment unit, a refueling judgment unit, and a communication unit. The state judgment unit determines whether to take anti-drip measures based on a preset angle and the angle between the extension direction of the refueling gun barrel and the horizontal plane to generate a posture control instruction. The refueling judgment unit determines whether to end the refueling process based on the liquid level detection result, the state of the refueling machine, and the refueling flow rate to generate a refueling control instruction. The communication unit communicates with the refueling machine, the state detection module, and the refueling control module.

[0080] Specifically, the state judgment unit executes the following logic: With the horizontal plane as the reference plane, vertical upward is -90°, and vertical downward is +90°, the anti-drip oil coordinate system is determined. When the angle between the extension direction of the refueling gun barrel and the horizontal plane belongs to [-90°, α1], the attitude control instruction of the anti-drip oil unit 5 in the closed state detection module is generated, where α1 represents the preset angle. When the angle between the extension direction of the refueling gun barrel and the horizontal plane belongs to (α1, +90°], the attitude control instruction of the anti-drip oil unit 5 in the open state detection module is generated.

[0081] Specifically, the refueling judgment unit executes the following logic: when the refueling button on the refueling gun is pressed, it first determines whether the liquid level injected into the container is above the liquid level detection unit 2. If it is below the liquid level, it proves that the oil in the refueling container is full, and the refueling machine stop command is fed back. If it is not above the liquid level, the refueling machine starts; then it determines whether the refueling machine starts normally. If the refueling machine does not start normally, the refueling machine page alarms and displays "refueling machine oil pump failure". If the refueling machine starts normally, the refueling controller of the refueling gun is turned on; then it determines whether the refueling flow is normal. If the refueling flow is abnormal, the refueling machine stops and alarms, and the refueling machine page displays "oil gun failure". If the refueling flow is normal, refueling starts, and then returns to the liquid level detection unit 2. If it is full, the refueling machine stops and the refueling process is completed.

[0082] Specifically, after the communication unit collects information, it effectively transmits and receives information through the low-power IoT technology ZigBee for the state control of the gas pump. Further, after the communication unit collects information, it effectively transmits and receives information through the low-power IoT technology LoRa for the state control of the gas pump. In one embodiment, after the communication unit collects information, it effectively transmits and receives information through the low-power IoT technology FSK for the state control of the gas pump.

[0083] In the present invention, the control module 11 is the brain of the fuel gun, which collects and processes the status of the fuel gun, such as flow rate, fuel gun posture, receiving and sending fuel dispenser information, etc., to achieve intelligence.

[0084] In one embodiment, Figure 1 As shown, the electronic intelligent fueling gun provided by the present invention comprises: a positioning module 10, which is arranged on the fueling gun body and is used to position the fueling gun.

[0085] Specifically, the present invention is an electronic fueling gun, and a positioning module 10 can be added to position the fueling gun to strengthen the supervision of the safe operation of the gas station. Furthermore, the positioning module 10 uses a Beidou positioning chip with an error accuracy of less than 1m, which has a good effect on the management of the gas station and the effective unblocking of the refueling vehicles.

[0086] In one embodiment, Figure 1As shown, the electronic intelligent fueling gun provided by the present invention comprises: a battery 12, which is arranged in the fueling gun body, meets the waterproof and explosion-proof levels, and is used to receive wireless charging energy when the fueling gun is idle.

[0087] Specifically, the electronic intelligent fueling gun provided by the present invention is equipped with a rechargeable battery, and the waterproof level of the battery compartment is greater than IP68, the battery explosion-proof level is greater than ExdⅡBT4, and a wireless charging module is provided at the gun hanging place of the fuel dispenser to ensure that the fueling gun can be charged when idle, thereby ensuring the effective operation of the fueling gun around the clock.

[0088] Furthermore, the battery 12 uses a lithium battery and is equipped with a wireless charging module. A wireless charger is installed on the fuel dispenser. When the fuel dispenser gun is idle, the fuel dispenser gun is wirelessly charged to ensure real-time monitoring of the fuel dispenser gun.

[0089] In one embodiment, Figure 1 As shown, the electronic intelligent fueling gun provided by the present invention comprises: a flow control module 17, which is arranged in the fueling pipeline and is used to collect statistics on the fueling status and fueling flow of the fueling pipeline.

[0090] Specifically, the electronic intelligent fueling gun provided by the present invention is equipped with a flow detection module 17 to perform detailed detection of the fueling status and serve as one of the effective bases for opening or closing the fueling gun.

[0091] Furthermore, the flow control module 17 monitors the refueling flow status, uploads it to the refueling system, compares it with the monitoring data of the flow meter of the refueling machine, and monitors the real-time operating status of the refueling gun.

[0092] In one embodiment, the flow control module 17 is not provided in the fuel gun, and the fuel gun detection data is provided by the fuel dispenser as a condition for determining whether to start the fuel gun.

[0093] The electronic intelligent refueling gun provided by the present invention uses a liquid level sensor to detect the liquid level injected into the container. Compared with the traditional mechanical refueling gun, the present invention has more accurate liquid level detection results for the container (such as a car tank), effectively reduces false alarms of the refueling gun liquid level and start-up errors, and can increase refueling efficiency.

[0094] The electronic intelligent fueling gun provided by the present invention can monitor the operating status of the fueling gun in real time through the status detection module, thereby effectively avoiding safety accidents caused by damage to the fueling gun.

[0095] The electronic intelligent refueling gun provided by the present invention can effectively realize the intelligent interconnection between the refueling gun and the refueling machine through the control module 11, thereby increasing the intelligence level of the refueling system.

[0096] The present invention is mainly used in gas station refueling machine equipment. The present invention realizes the intelligence and risk control level of the refueling process from the refueling terminal, monitors the refueling flow and the real-time status of the refueling gun, and improves the information level of the overall refueling process.

[0097] The novel electronic intelligent fueling gun provided by the present invention improves the intelligence level of gas stations, lays a foundation for the intelligence of the entire refueling process, and has good development prospects.

[0098] Figure 4 A flowchart of the steps of a refueling status detection method based on an electronic intelligent refueling gun according to an embodiment of the present invention is shown.

[0099] like Figure 4 As shown, in step S401, the posture of the refueling gun is detected in real time by a state detection module to generate a posture sensing result, and anti-drip oil control is performed according to the posture control instruction.

[0100] Specifically, the attitude sensing unit 9 in the state detection module senses the angle between the extension direction of the refueling gun nozzle 1 and the horizontal plane in real time to generate an attitude sensing result. The anti-drip unit 5 in the state detection module is turned on or off according to the attitude control instruction. When the anti-drip unit 5 is turned on, the refueling gun has the anti-drip capability, and when the anti-drip unit 5 is turned off, the refueling gun does not have the anti-drip capability.

[0101] like Figure 4 As shown, in step S402, during the refueling process, the refueling control module detects the liquid level injected into the container to generate a liquid level detection result, and performs refueling control according to the refueling control instruction.

[0102] Specifically, in the refueling state, the liquid level detection unit 2 in the refueling control module detects whether the liquid level injected into the container contacts the liquid level detection unit 2 to generate a liquid level detection result. The refueling controller in the refueling control module is turned on or off according to the refueling control instruction, wherein when the refueling controller is turned on, the refueling pipeline is turned on, and when the refueling controller is turned off, the refueling pipeline is closed.

[0103] like Figure 4 As shown, in step S403, a control module generates a posture control instruction based on the posture sensing result, and generates a refueling control instruction based on the liquid level detection result.

[0104] Specifically, the state judgment unit in the control module determines whether to take anti-drip measures based on the preset angle and the angle between the extension direction of the refueling gun barrel and the horizontal plane to generate a posture control instruction. The refueling judgment unit in the control module determines whether to end the refueling process based on the liquid level detection result, the state of the refueling machine and the refueling flow to generate a refueling control instruction. The communication unit in the control module communicates with the refueling machine, the state detection module, and the refueling control module.

[0105] Figure 5 A flow chart of the steps of a refueling control method according to an embodiment of the present invention is shown.

[0106] In one embodiment, Figure 5 As shown, refueling control is performed through steps S501-S509.

[0107] like Figure 5 As shown, in step S501, a refueling instruction is given. Specifically, when the refueling button on the refueling gun is pressed, it indicates that the refueling gun has received a refueling instruction.

[0108] like Figure 5 As shown, in step S502, it is determined whether the liquid level injected into the container is above the liquid level sensor. Specifically, after receiving the refueling instruction, it is determined whether the liquid level injected into the container is above the liquid level sensor in the refueling control module. In one embodiment, the liquid level sensor uses a photoelectric liquid level sensor, and the signal value of the sensor in the air is measured as a, and then the signal value of the sensor in 92 gasoline is measured as b. The value b is significantly different from the value a, so it is determined that when the signal value suddenly changes, it is considered that the liquid level is detected.

[0109] like Figure 5 As shown, if the judgment result of step S502 is yes, it proves that the oil in the refueling container is full, then the process proceeds to step S503 to generate a fuel dispenser stop instruction. If the judgment result of step S502 is no, then the process proceeds to step S504 to generate a fuel dispenser start instruction.

[0110] like Figure 5 As shown, in step S505, it is determined whether the fuel dispenser is started normally. If the determination result of step S505 is no, the process proceeds to step S506, and a fuel dispenser alarm instruction is generated, that is, the fuel dispenser is not started normally, and the fuel dispenser page alarms and displays "fuel dispenser oil pump failure". If the determination result of step S505 is yes, the process proceeds to step S507, and a fueling control instruction for turning on the fueling controller in the fueling control module is generated, that is, if the fuel dispenser is started normally, the fueling controller of the fueling gun is turned on.

[0111] like Figure 5As shown, in step S508, it is determined whether the refueling flow is normal. If the determination result of step S508 is no, then in step S509, a fuel dispenser stop and alarm instruction is generated, that is, if the refueling flow is abnormal, the fuel dispenser stops and alarms, and the fuel dispenser page displays "fuel gun failure". If the determination result of step S508 is yes, then it returns to step S502 to determine whether the liquid level injected into the container is above the liquid level sensor in the refueling control module.

[0112] Figure 6 A schematic diagram of the tilt angle of a fuel gun according to an embodiment of the present invention is shown.

[0113] In one embodiment, Figure 6 As shown, the anti-drip oil control is performed through the following steps: Taking the horizontal plane as the reference plane, vertically upward is -90°, and vertically downward is +90°, determine the anti-drip oil coordinate system. When the angle between the extension direction of the refueling gun barrel and the horizontal plane belongs to [-90°, α1], the attitude control instruction of the anti-drip oil unit in the closed state detection module is generated, where α1 represents a preset angle, such as 30°. When the angle between the extension direction of the refueling gun barrel and the horizontal plane belongs to (α1, +90°], the attitude control instruction of the anti-drip oil unit in the open state detection module is generated.

[0114] Specifically, whether to take anti-drip oil measures is determined based on the inclination angle of the gun body. The horizontal muzzle outlet is taken as the zero point, the downward inclination angle is α, and the upward inclination angle is -α. Figure 6 As shown, the specific position information calibrates the posture sensing unit 9. When α>30°, the anti-drip oil unit 5 is turned on, and when α≤30°, the anti-drip oil unit 5 is turned off.

[0115] Furthermore, for special working conditions, the fueling gun is provided with a physical solenoid valve switch lock, which is turned on by default in normal working conditions, and the physical solenoid valve relies on the posture sensing unit 9 for automatic switch control. In special working conditions, the physical solenoid valve switch lock is closed, and the physical solenoid valve is always in the open state, which is suitable for refueling at any angle. The posture sensing unit 9 is calibrated with the muzzle horizontal zero point. If an abnormal state occurs, it is considered that the fueling gun has slipped.

[0116] The electronic intelligent refueling gun provided by the present invention can also be used in conjunction with a computer-readable storage medium, on which a computer program is stored. The computer program is executed to run a refueling status detection method based on the electronic intelligent refueling gun.

[0117] A computer program can run computer instructions, which include computer program code. The computer program code may be in source code form, object code form, executable file, or some intermediate form.

[0118] Computer-readable storage media may include: any entity or device that can carry computer program code, recording media, USB flash drives, mobile hard disks, magnetic disks, optical disks, computer memory, read-only memory (ROM), random access memory (RAM), electrical carrier signals, telecommunication signals, and software distribution media, etc.

[0119] It should be noted that the content contained in computer-readable storage media can be appropriately increased or decreased based on the requirements of legislation and patent practices in the jurisdiction. For example, in some jurisdictions, based on legislation and patent practices, computer-readable storage media do not include electrical carrier signals and telecommunications signals.

[0120] In one embodiment, a traditional mechanical refueling gun is used as a reference and compared with the electronic intelligent refueling gun provided by the present invention. The test environment temperature is 28°C. When the refueling flow rate exceeds 40L / min, the mechanical oil gun has a false alarm of gun jumping, and it is not actually full. The electronic intelligent refueling gun provided by the present invention does not have a false alarm of gun jumping due to the detection of liquid level. In addition, the electronic intelligent refueling gun provided by the present invention includes an anti-drip unit 5 and a posture sensing unit 9, and there is no dripping phenomenon in the gun body of the refueling gun.

[0121] In summary, the present invention provides an electronic intelligent fueling gun, which has the following advantages compared with the prior art:

[0122] (1) The electronic intelligent refueling gun provided by the present invention uses a liquid level sensor to detect the liquid level of the container being injected. Compared with the traditional mechanical refueling gun, the present invention has a more accurate liquid level detection result for the container being injected (such as a car tank), effectively reducing the false alarm of the liquid level of the refueling gun and the start-up error, and can increase the refueling efficiency;

[0123] (2) The electronic intelligent fueling gun provided by the present invention can monitor the operating status of the fueling gun in real time through the status detection module, effectively avoiding safety accidents caused by damage to the fueling gun;
