[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1, reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a method for automatically spraying lubricant when a locomotive is running. This device monitors the running status of the locomotive in real time through a gyroscope sensor and sends the obtained information to the PLC control processor in the form of an electrical signal.

[0032] Among them, the gyroscope sensor is mainly used to capture the driving status of the locomotive and observe whether the locomotive is accelerating, decelerating or turning. The captured information is then sent to the PLC control processor through an electrical signal and then processed by the PLC control processor.

[0033] Furthermore, by programming the PLC control processor, the received electrical signal is converted into a corresponding operation instruction.

[0034] Preferably, the system inside the PLC control processor is programmed first, so that after receiving the electrical signal, the PLC control processor can run according to the programmed program to complete the corresponding instructions, and then issue corresponding instructions according to the real-time operating conditions.

[0035] Furthermore, the operation of the lubricating oil spraying device is controlled by instructions issued by the PLC control processor, so that the locomotive sprays different amounts of lubricating oil and spraying forms when accelerating, decelerating, and turning.

[0036] Among them, the spraying device is used to spray lubricating oil onto the wheels, so that the wheels and the rails are more lubricated, preventing excessive friction between the wheels, causing the wheels to derail.

[0037] Preferably, the PLC control processor receives the locomotive driving status captured by the gyro sensor, and then issues corresponding instructions through the edited program, so that the locomotive sprays different amounts of lubricating oil and different spraying angles when accelerating, decelerating, and turning.

[0038] In summary: the gyroscope sensor is used to monitor the locomotive's driving status in real time, and the information is sent to the PLC control processor in the form of electrical signals, realizing comprehensive monitoring of the locomotive's acceleration, angular velocity and attitude angle, ensuring the timeliness and accuracy of lubricant spraying. The PLC control processor has real-time data processing and analysis capabilities, and can dynamically adjust the working parameters of the lubricating oil spraying device according to the real-time driving status of the locomotive, optimize the lubrication effect, reduce resource waste, and improve the intelligence level of the system, thereby extending equipment life, reducing maintenance costs, improving operational safety, and contributing to energy conservation and environmental protection, comprehensively improving the intelligence, safety and economy of locomotive operation.

[0039] Example 2, reference Figure 1 , Figure 2 and Figure 6 , which is the second embodiment of the present invention, is the second embodiment of the present invention, which provides a device for automatically spraying lubricant when a locomotive is running, and includes: a gyroscope sensor capable of monitoring the acceleration, angular velocity and attitude angle of the locomotive to achieve comprehensive monitoring of the locomotive's running status.

[0040] Among them, the gyroscope sensor can provide all-round dynamic information of objects in three-dimensional space, so that the control system can make precise adjustments on multiple axes, thereby enabling the locomotive to fully detect the driving status of the locomotive in real time during driving.

[0041] Furthermore, the PLC control processor has real-time data processing and analysis capabilities, and can adjust the working parameters of the lubricating oil spraying device according to the real-time driving status of the locomotive to achieve the optimal lubrication effect.

[0042] Preferably, the PLC control processor has high flexibility. Through programming, the PLC can easily change the control logic to adapt to different production needs without changing the hardware circuit.

[0043] Furthermore, the lubricating oil spraying device includes a plurality of nozzles, each of which can independently adjust the spraying amount and spraying angle according to the instructions of the PLC control processor to meet the lubrication needs of the locomotive under different driving conditions.

[0044] Preferably, by setting up a plurality of adjustable nozzles, the nozzles can spray at multiple angles, and then the PLC control processor controls the direction and spraying amount of the nozzle, thereby making the lubrication effect better and reasonably saving lubricating oil, achieving the effect of intelligence and energy saving.

[0045] In summary: First, by editing the running program inside the PLC control processor, the gyroscope sensor collects the locomotive's driving status, and then issues corresponding instructions, the nozzle is adjusted to the optimal angle when the locomotive turns, decelerates and accelerates, and then the corresponding metered lubricant is sprayed, so that the sprayed lubricant has the best lubrication effect, optimizes the lubrication effect, reduces resource waste, and improves the intelligence level of the system, thereby extending equipment life, reducing maintenance costs, and improving operational safety.

[0046] Example 3, reference Figure 2 to Figure 6 , which is the third embodiment of the present invention, includes: a spraying control system 100, including a protection module 101, a control module 102 arranged on the protection module 101, a sensing module 103 arranged on the protection module 101, a conveying module 104 arranged on the control module 102, and a spraying module 105 arranged on the conveying module 104.

[0047] The protection module 101 is used to protect the control module 102 so that the protection module can operate normally, and the control module 102 is used to control the conveying module 104 and the spraying module 105 so that the two modules can operate normally, and then the lubricant can be sprayed out in time when the locomotive is running.

[0048] Furthermore, the protection module 101 includes a control box 101a, a control base plate 101b disposed inside the control box 101a, a cover plate 101c disposed on the top of the control box 101a, and a connector 101d disposed on the lower side of the control box 101a.

[0049] Among them, the control box 101a is the main part of the protection module 101, which provides protection for the internal electronic components and control system to prevent the external environment such as dust, moisture, oil, etc. from damaging the internal components; the control base plate 101b is a platform for installing the PLC control processor and other electronic components, which fixes these components in appropriate positions and provides necessary circuit connections; the cover plate 101c is located at the top of the control box 101a, which is used to close the control box 101a to prevent external impurities from entering, and at the same time facilitate opening for maintenance; the connector 101d is located on the lower side of the control box 101a, which is used to connect other parts of the lubricating oil spraying device, such as nozzles, oil pipes, etc., and may also be an electrical connection point.

[0050] Furthermore, the control module 102 includes a PLC processor 102a and a relay 102b disposed on the control base plate 101b, an indicator light 102c disposed on the cover plate 101c, and a control switch 102d disposed on the cover plate 101c and below the corresponding indicator light 102c.

[0051] Among them, the PLC (Programmable Logic Controller) processor is the brain of the control module 102, which is responsible for receiving signals from sensors, processing them according to preset programs, and then outputting control instructions to actuators (such as relays 102b, solenoid valves 104a, etc.); relays 102b are an electrical control device that can use smaller currents to control larger currents. After the PLC processor 102a issues an instruction, the relay 102b can be used to control the solenoid valves 104a, motors and other actuators in the lubricating oil spraying device; the indicator light 102c is used to display the current status of the system, such as running, stopping, faults, etc., which provides operators with an intuitive means of system monitoring; the control switch 102d allows operators to manually intervene in the system, such as starting, stopping, resetting, etc. It is directly connected to the PLC processor 102a to input operating instructions into the system.

[0052] Furthermore, the sensing module 103 includes a processing box 103a disposed on the outer wall of the control box 101a, a connecting piece 103b disposed on the outer wall of the processing box 103a, and a sensing head 103c disposed on the connecting piece 103b.

[0053] The processing box 103a is the main part of the sensing module 103, which provides a fixed installation location and protective environment for the sensing head 103c and other electronic sensing elements. The processing box 103a may contain electronic components such as circuit boards and signal processors for processing the signals collected by the sensing head 103c; the connector 103b is used to fix the sensing head 103c on the outer wall of the processing box 103a, and at the same time provide an electrical connection between the sensing head 103c and the circuit board inside the processing box 103a; the sensing head 103c is the part of the sensing module 103 that directly contacts the monitored object (such as the motion state, temperature, lubricating oil flow, etc. of the locomotive parts), and is used to collect relevant physical information and convert it into electrical signals.

[0054] Preferably, when the induction head 103c detects a state change of a locomotive component, it generates corresponding electrical signals, which are transmitted to the circuit board inside the processing box 103a through the connector 103b, and after processing, the signals are transmitted to the PLC processor 102a. The PLC processor 102a adjusts the operation of the lubricating oil spraying device according to these signals, thereby realizing intelligent lubrication control.

[0055] Furthermore, the delivery module 104 includes a solenoid valve 104a disposed on the outer wall of the control box 101a, a pneumatic pump 104b disposed on the solenoid valve 104a, and a first high-pressure hose 104c disposed on the pneumatic pump 104b.

[0056] Among them, the solenoid valve 104a is a valve that uses the electromagnetic principle to control the flow of fluid. It opens or closes under the command of the control module 102, thereby controlling the flow path of the lubricating oil; the pneumatic pump 104b is a device that uses compressed air as a power source to transport fluid. It extracts the lubricating oil from the oil tank and transports it to the high-pressure hose through the control of the solenoid valve 104a; the first high-pressure hose 104c is used to connect the pneumatic pump 104b and the distributor 105a, and is the main channel for transporting the lubricating oil. It needs to withstand a certain pressure to ensure that the lubricating oil can smoothly reach the designated spraying position.

[0057] Preferably, when the PLC processor 102a determines that lubricating oil needs to be sprayed according to the signal of the sensing module 103, it sends an opening signal to the solenoid valve 104a; after the solenoid valve 104a receives the signal, the valve core moves to open the oil circuit between the pneumatic pump 104b and the oil storage tank; the pneumatic pump 104b starts working under the drive of compressed air, extracts lubricating oil from the oil storage tank and transports it to the spraying module 105 through the first high-pressure hose 104c, thereby allowing the lubricating oil to be sprayed out through the spraying module 105.

[0058] Furthermore, the spray module 105 includes a distributor 105a disposed on the first high-pressure hose 104c, a second high-pressure hose 105b disposed on the distributor 105a, and a spray head 105c disposed on the second high-pressure hose 105b.

[0059] Among them, the distributor 105a is the core component of the spray module 105, which receives the lubricating oil from the first high-pressure hose 104c and distributes the lubricating oil to multiple second high-pressure hoses 105b as needed, thereby realizing the oil supply to multiple nozzles 105c; the second high-pressure hose 105b connects the distributor 105a and the nozzle 105c, and is responsible for transporting the lubricating oil from the distributor 105a to each nozzle 105c. Each hose may correspond to one or more nozzles 105c to realize multi-point spraying; the nozzle 105c is the final actuator of the spray module 105, which sprays the lubricating oil transported by the high-pressure hose evenly to the lubrication point in the form of atomization or injection. The shape and design of the nozzle 105c will affect the injection angle, range and atomization effect of the oil.

[0060] Preferably, after the delivery module 104 delivers the lubricating oil to the distributor 105a, the distributor 105a distributes the lubricating oil to each second high-pressure hose 105b according to the instruction of the PLC processor 102a, and the lubricating oil is delivered to each nozzle 105c through the second high-pressure hose 105b. The nozzle 105c sprays the lubricating oil to the designated lubrication point of the locomotive according to preset parameters (such as spraying amount, spraying angle, etc.). The PLC processor 102a can adjust the spraying parameters of the nozzle 105c in real time according to the information provided by the sensing module 103 to optimize the lubrication effect.

[0061] In summary: after the spray control system 100 is started, the PLC processor 102a in the protection module 101 is initialized and loaded with a preset program, and at the same time, the indicator light 102c of the control module 102 displays the system status; the sensor head 103c of the sensing module 103 monitors the status of the locomotive components, converts the changes into electrical signals and transmits them to the internal circuit board of the processing box 103a, and the PLC processor 102a determines whether it is necessary to spray lubricating oil; if necessary, the PLC processor 102a sends a command to activate the relay 102b to control the conveying module 10 The solenoid valve 104a of 4 is opened, and the pneumatic pump 104b extracts the lubricating oil and delivers it to the distributor 105a of the spraying module 105 through the first high-pressure hose 104c; the distributor 105a distributes the lubricating oil to the second high-pressure hose 105b according to the instruction and delivers it to each nozzle 105c, and the nozzle 105c sprays the lubricating oil to the designated lubrication point according to the preset parameters; the operator can manually intervene in the system through the control switch 102d, and the PLC processor 102a adjusts the spraying parameters in real time according to the information of the sensing module 103 to optimize the lubrication effect.
