Description

Technical Field

[0001] The present invention belongs to the technical field of gas station safety control, and particularly relates to a method and device for prompting gun removal for use in a gas station. Background Art

[0002] In the prior art, when a vehicle enters a gas station for refueling, it is mainly completed through a fuel dispenser, an attached fuel pipe, and a fuel gun. During refueling, the fuel gun is inserted into the fuel tank opening, and the fuel flows through the fuel dispenser, the fuel pipe, and the fuel gun into the fuel tank. This technology has obvious defects, that is, the vehicle can start and drive freely without control. During or after refueling, if the vehicle drives away when the fuel gun is not detached from the vehicle body, the pulling force generated by the vehicle will cause equipment damage, fuel leakage, or trigger a production safety accident.

[0003] According to the prior art, when automobile manufacturers produce refueling vehicles, they do not add a design to restrict driving when the vehicle body has a gun, and it is impossible to solve the above problems at the vehicle end.

[0004] However, the above problems are widespread, and production safety accidents caused by vehicles driving away without removing the gun have occurred frequently. Therefore, there is an urgent need for a method and device for prompting gun removal for use in a gas station, so that the vehicle can only shift gears and drive after the fuel gun is separated from the vehicle.

[0007] The first aspect of the present invention provides a method for prompting gun removal for use in a gas station, including: Setting the states of the fuel gun, which are the initial state and the working state respectively; Setting the states of the interlock device, which are the initial state and the working state respectively; Obtaining the state of the fuel gun through a control device; Sending a synchronization command to the interlock device through the control device; If the fuel gun is in the initial state, it is determined that the fuel gun has been separated from the vehicle body, the interlock device enters the initial state, which has no restrictive effect on the vehicle, and the vehicle can drive freely; If the fuel gun is in the working state, it is determined that refueling is in progress. At this time, the interlock device also enters the working state to restrict the vehicle from driving, and the vehicle cannot start, achieving the effect of safety control.

[0008] The second aspect of the present invention provides a device for prompting gun removal for use in a gas station, including: A control device for detecting the initial state and working state of a fuel nozzle, and issuing information instructions to other devices according to the state of the fuel nozzle; A vehicle frame device that receives signals from the control device, synchronizes with the state of the fuel nozzle, is inoperative in the initial state, allows the vehicle to pass freely, and restricts vehicle travel in the working state; An interception device that receives signals from the control device, synchronizes with the state of the fuel nozzle, is inoperative in the initial state, allows the vehicle to pass freely, and is used to prompt the driver's attention in the working state.

[0009] In the above implementation process, the present invention can accurately monitor the state of the fuel nozzle in real time and make linkages, preventing the vehicle from traveling when the fuel nozzle is not separated from the vehicle body, playing a role in safety protection.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention provides a solution to the safety hazards existing in the prior art, eliminates the possibility of accidents caused by the vehicle driving without removing the fuel nozzle, and improves the intrinsic safety of the gas station; 2. The methods and devices used do not require large-scale renovation of the gas station, and the economic investment is small. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments. Obviously, the specific embodiments described are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0013] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0014] Refer to Figure 1 As shown, when the fuel nozzle is hung on the nozzle holder, it is in the initial state. At this time, the control device detects the initial state, and the vehicle frame device and the interception device are both in the initial state.

[0015] Refer to Figure 2 As shown, when the fuel nozzle leaves the nozzle holder, it is in the working state. At this time, the control device detects the working state, and the vehicle frame device and the interception device both enter the working state.

[0016] Refer to Figure 3 As shown, when the refueling vehicle drives into the upper part of the vehicle frame device and stops stably, the staff picks up the fuel nozzle to refuel. When the fuel nozzle leaves the base, it triggers the fuel nozzle to enter the working state from the initial state. At this time, the control device operates and issues a start work instruction to the vehicle frame device and the interception device. The vehicle frame device and the interception device are powered on and operate, entering the working state.

[0017] Further, for the car system, after the vehicle frame device is powered on, the mechanical device operates to lift the vehicle, so that the tires are separated from the ground, and the vehicle cannot move even if it is started by ignition.

[0018] Optionally, for heavy trucks, after the vehicle frame device is powered on, the mechanical device operates to lock the wheels, and the vehicle cannot move even if it is started by ignition.

[0019] Further, after the interception device is powered on, the interception ropes are raised in front of and behind the vehicle to prompt the driver that refueling is in progress and not to drive away.

[0020] After refueling, the staff places the fuel nozzle on the nozzle holder, and the fuel nozzle returns to the initial state. The control device issues a stop work instruction, and the vehicle frame device and the interception device are powered off and stop operating simultaneously.

[0021] Further, after the vehicle frame device is powered off, the mechanical device returns to its original state, the vehicle restriction is released, and it returns to the freely drivable state.

[0022] Further, after the interception device is powered off, the interception ropes are retracted, and the vehicle can drive away without hindrance.

[0023] It should be noted that the operation time of the vehicle frame device and the interception device is extremely short and does not affect the refueling experience of customers.

[0024] It can be seen that by implementing the prompt gun-picking method and device for gas stations described in this embodiment, without affecting the refueling experience of customers, it can accurately judge the position of the fuel nozzle, prompt the staff to pick up the gun in time, restrict the driving of the vehicle when the fuel nozzle is not separated from the vehicle body, eliminate the safety hazard of the vehicle driving with the gun, and improve the intrinsic safety of the gas station.

[0025] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make changes, modifications, substitutions, and variations to the above embodiments without departing from the spirit and scope of the present invention, and these all fall within the protection scope of the present invention.
