Description

Technical Field

[0001] This invention pertains to rail transit lubrication systems, specifically to auxiliary equipment for railway turnout external locking switching devices, and particularly relates to an automatic lubrication system and method based on a controllable electric push rod. Background Technology

[0002] As shown in Figure I, in the existing railway turnout external locking conversion device, the turnout is unlocked and locked by pushing or pulling the locking hook with its locking rod. Since the turnout needs to be repeatedly turned back and forth, the friction between the upper surface of the locking rod and the lower surface of the locking hook at oil injection point A, and between the locking surface of the locking hook and the locking surface of the locking iron at oil injection point B, is very large and easily causes wear. According to the changes in climate temperature, the frequency of turnout operation, and different working conditions, the number of times and the amount of oil injected into oil injection points A and B in the figure for each group of turnouts are set to keep them in a lubricated state, reduce wear, and ensure the normal operation of the turnout external locking conversion device.

[0003] Currently, there are three main types of lubrication devices for turnout external locking switching devices: One type is a mechanical automatic lubrication device. Its principle is to use the power generated by the turnout's own movement to drive the pressure transmission rod of the lubricator, causing the plunger on the pump body to spray oil onto the friction parts of the turnout, thus automatically lubricating the turnout external locking device. This type of lubrication requires the turnout to be switched before lubrication, making pre-lubrication impossible. If a turnout is not frequently switched, prolonged lack of lubrication can easily lead to jamming when unlocking, affecting unlocking. Furthermore, the frequency of switching varies for each turnout, requiring maintenance personnel to check and replenish the remaining oil in the tank individually, failing to reduce their workload. Another type is a gear pump-type lubrication device, also a mechanical lubrication device. Its lubrication volume cannot be adjusted, and its implementation is poor. When the turnout needs to operate, it is necessary to pre-energize it and pre-pressurize the gear pump for lubrication. In cases of low temperatures, pre-heating is also required to ensure oil fluidity for successful lubrication. Another type is a programmable controllable lubrication device. While superior to mechanical lubrication devices, it allows for pre-setting the number of lubrication cycles and adjusting the oil volume based on temperature and switch activity. However, it requires solar power; without sunlight, it cannot store electricity, and it lacks monitoring of remaining oil levels, necessitating manual on-track inspection. All three types of devices, to varying degrees, increase the time maintenance personnel spend on the track during maintenance windows. They either cannot adjust the single lubrication volume, cannot monitor remaining oil levels, or, while they can adjust the lubrication volume, they lack real-time, comprehensive monitoring and lubrication implementation capabilities, thus failing to provide a truly controllable and intelligent lubrication system.

[0004] Although Chinese patent CN117685488A proposes an oil injection strategy based on ambient temperature, it only considers the single factor of temperature, and the generation of the oil injection strategy depends on cloud feedback, resulting in a large response delay. It cannot adapt to complex and ever-changing field environments such as wind, sand, rain, snow, and sunlight in real time. It also does not consider deep integration with existing turnout monitoring systems, and it does not disclose a specific structural implementation scheme for a compact, integrated oil injection device for the specific turnout structure of "externally locked turnouts". Summary of the Invention

[0005] One of the objectives of this invention is to provide an automatic oil injection and lubrication system and method based on a controllable electric push rod. During the service life of the oil injection system, there is no need to manually monitor the oil level in the oil tank. An alarm can be triggered when the oil level reaches the lower limit set by the system, so as to reduce the time that maintenance personnel spend on the road, save manpower and resources, and provide a new technical means to ensure driving safety.

[0006] The second objective of this invention is to provide an automatic oil injection and lubrication system and method based on a controllable electric push rod. It controls the oil injection frequency and amount based on the switching frequency of turnouts at different locations on site, the degree of influence of weather conditions such as wind, sand, rain, snow, sun exposure, and changes in ambient temperature and humidity on the turnouts in different seasons. It can also remotely and periodically inject oil into turnouts that are not frequently used, preventing situations where turnouts cannot be unlocked when they need to be unlocked.

[0007] The third objective of this invention is to provide an automatic oil injection and lubrication system and method based on a controllable electric push rod, which aims to solve the problems in the prior art such as the single oil injection strategy factor, untimely response, isolation from the existing monitoring system, and lack of a dedicated integrated structure for externally locking turnouts. It achieves adaptive and precise oil injection based on multiple environmental factors and turnout operation frequency, reduces manual intervention, and improves safety and reliability.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: It relates to an automatic oil injection and lubrication system based on a controllable electric actuator, comprising an indoor monitoring host, an outdoor oil injection unit, and an oil quantity information detection unit. The outdoor oil injection unit includes an oil tank, an electrical control box, an electro-hydraulic mechanism composed of an electric actuator and a hydraulic cylinder, an oil injection hose, and an environmental detection module for detecting environmental parameters; its characteristic is:

[0009] The indoor monitoring host and the turnout gap monitoring system are integrated on the same hardware platform and software interface.

[0010] The indoor monitoring host has a built-in oil injection control module. The oil injection control module has a pre-stored mapping table that associates various environmental parameters with oil injection strategies. The environmental parameters include at least temperature, humidity, rain and snow detection information, and wind and sand detection information.

[0011] The oil level detection unit is an algorithm that obtains the oil level information in the tank based on the number of times oil is injected into the refueling point and the amount of oil injected each time, and determines to send a refueling command to the tank based on the oil level information, so as to realize automatic refueling of the tank.

[0012] During operation, the monitoring host receives real-time environmental data from the environmental detection module, information on the number of positioning and reversing actions of the turnout, and oil level information from the oil quantity information detection unit. The oil injection control module queries the mapping table locally in real time, autonomously generates and sends oil injection control commands to the electrical control box, which then controls the electro-hydraulic mechanism to perform the oil injection operation.

[0013] Oil injection is triggered when any of the following conditions are met:

[0014] a) The number of times a turnout operates at a certain location reaches a first preset threshold;

[0015] b) The time since the last oil injection reaches the second preset threshold, which is dynamically adjusted based on the current environmental parameters.

[0016] The outdoor oil filling unit includes an oil tank and a housing. The housing includes a top cover, and the oil tank and the top cover are connected by hinges. The electro-hydraulic mechanism includes an electronic actuator and a cylinder assembly, which are fixed to a control board. The electrical control box is also fixed to the control board. The control board is also equipped with an adjustment bracket to position the electronic actuator. The top cover is equipped with a foldable handle. The housing also includes a cryogenic solenoid valve, a flow divider, an inlet oil pipe, and an outlet oil pipe assembly. The outlet oil pipe assembly is connected to the cryogenic solenoid valve and is used to deliver lubricating oil to the oil filling point.

[0017] The electronic control box is equipped with: a full oil setting button, used to send a full oil signal to the monitoring host after the oil tank is filled; a positioning manual oil filling button; and a reverse manual oil filling button; wherein, each button supports inching oil filling and long-press continuous oil filling.

[0018] The monitoring host and the outdoor oil injection unit are connected by a pair of cables using carrier communication for power supply and data transmission.

[0019] The monitoring host's software interface integrates a manual oil injection control unit, an oil injection parameter setting unit, an oil injection history query unit, and an alarm information display unit. The oil injection history query unit records oil injection data including oil injection time, oil injection location, oil injection volume, and environmental data when oil injection is triggered.

[0020] This invention relates to an automatic oil injection and lubrication method based on a controllable electric push rod, characterized by the following steps: real-time collection of environmental data and the number of turnout operations via an environmental detection module and a switch machine; autonomous generation of an oil injection command by querying a pre-stored strategy mapping table locally based on the environmental data and the number of turnout operations; and issuance of the oil injection command to an outdoor oil injection unit to control it to perform the oil injection operation.

[0021] The steps of the query strategy mapping table include: adjusting the basic oiling cycle based on real-time collected temperature and humidity data; generating an instruction to shorten the oiling cycle when rain and snow detection information indicates rainfall or snowfall; generating an instruction to immediately execute an oiling command or increase the single oiling volume when wind and sand detection information indicates that wind speed or dust concentration exceeds a threshold; wherein, the query strategy mapping table includes a multi-parameter coupling strategy: multi-parameter coupling involves adopting a strategy of shortening the oiling cycle and reducing the single oiling volume in high temperature and high humidity environments; adopting a strategy of extending the oiling cycle and maintaining the standard oiling volume in low temperature and dry environments; immediately executing an enhanced oiling after rain or snow, ignoring cycle limitations; and adopting a strategy of periodically doubling the oiling volume in continuous wind and sand weather.

[0022] The present invention also includes an environmental trend prediction refueling step: the system continuously records the trend of environmental data changes; if severe weather such as rain, snow, or strong winds is predicted to occur, the system determines whether to perform preventive refueling in advance based on the prediction data before the weather event occurs.

[0023] The step of immediately executing the oil injection command further includes: determining the current environment type based on the real-time environmental data, wherein the environment type includes high temperature and high humidity, low temperature and dryness, rain and snow, or continuous wind and sand; and calling the corresponding multi-parameter coupling strategy in the oil injection strategy mapping table according to the determined environment type to dynamically adjust the oil injection parameters and achieve adaptive oil injection control.

[0024] The advantages of this invention are: it can share circuitry with turnout gap monitoring system equipment, is compatible with system software, and can also operate independently, providing a new high-tech means to ensure traffic safety. The system can intelligently and remotely control the lubrication of the turnout external locking device, meeting immediate lubrication needs, achieving intelligent control, maintaining good lubrication of the hook-lock components of the turnout external locking device, reducing and avoiding mechanical failures of the turnout external locking device caused by poor lubrication, improving the reliability of turnout switching, and extending service life. After the system is applied, the lubrication frequency and amount can be controlled according to the turnout switching frequency at different locations, and the degree of influence of weather conditions such as wind, sand, rain, snow, sun, and changes in ambient temperature and humidity on the turnout in different seasons. During the service life of the lubrication system, there is no need for manual monitoring of the oil level in the tank; an alarm will sound when the oil level reaches the system's set lower limit. It also reduces the time maintenance personnel spend on the track, saving manpower and resources.

[0040] To further illustrate the technical means and methods adopted by the present invention to achieve its intended purpose, the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0041] The embodiments of the present invention provide two main implementation methods, and their structural connection relationships and workflows are as follows: Example 1

[0042] like Figure 2 , Figure 3 Figure 4A and Figure 4B As shown, this invention relates to an automatic oil injection lubrication system and method based on a controllable electric actuator, including an indoor monitoring host, an outdoor oil injection unit, and an oil quantity information detection unit 33. The outdoor oil injection unit includes an oil tank 1, an electrical control box 5, an electro-hydraulic mechanism composed of an electronic actuator 3 and an oil cylinder, and an oil injection hose. It further includes an environmental detection module for detecting environmental parameters. The monitoring host and the turnout gap monitoring system are integrated on the same hardware platform and software operation interface, realizing deep integration of the automatic oil injection lubrication system and resources.

[0043] The host has a built-in oil filling control module, which pre-stores a mapping table related to various environmental parameters and oil filling strategies. The environmental parameters include at least temperature, humidity, rain and snow detection information, and wind and sand detection information. The mapping table is used to accurately represent the oil tank 1's oil filling information recorded by the oil quantity information detection unit 33 in different environments in the past, including the number of fillings and the amount of oil injected each time. The oil quantity in the oil tank 1 is calculated from the number of fillings and the amount of oil injected each time to determine whether to automatically refill the oil tank 1.

[0044] During operation, the monitoring host receives real-time environmental data from the environmental detection module and information on the number of turnout positioning actions. The oil injection control module queries the mapping table locally in real time, autonomously generates and sends oil injection control commands to the electrical control box 5. The electrical control box 5 controls the electro-hydraulic mechanism to perform the oil injection operation. The oil injection process of the electro-hydraulic mechanism is quantified into precise basic oil quantity units. The usage amount can be calculated from the basic oil quantity units, such as the injection amount at each injection point and the sum of the injection amounts at each injection point. The oil quantity in the oil tank 1 is deduced from the sum, and it is determined whether to add oil to the oil tank 1, thus realizing automatic oiling.

[0045] In order to quantify the oil injection process of the electro-hydraulic mechanism into precise basic oil quantity units, the electro-hydraulic mechanism includes: electronic push rod 3, output oil pipe assembly 16 and cryogenic solenoid valve 11. The electro-hydraulic mechanism receives the oil injection command issued by the electronic control box 5, opens the cryogenic solenoid valve 11, and pushes the lubricating oil to the external locking conversion oil injection point of the railway turnout through the output oil pipe assembly 16.

[0046] Since the timing and amount of lubricating oil used to propel the railway turnout external locking switch lubrication point are related to various environmental parameters and usage conditions, these various environmental parameters and usage conditions are represented by a mapping table of lubrication strategies. In this way, the mapping table can determine when and under what conditions lubrication is required. That is to say, the lubrication control module built into the monitoring host can obtain the lubrication command based on the mapping table of various environmental parameters and lubrication strategies, and the lubrication command is issued by the electrical control box 5.

[0047] The output oil pipe assembly 16 includes two output oil pipes that deliver lubricating oil to the fixed / reverse oil filling points respectively.

[0048] The oil injection hose is the oil pipe between the outdoor oil injection unit and the oil injection components. There are two oil injection hoses in total, which are connected to oil injection components at different distances from the outdoor oil injection unit, depending on the actual situation on site. Each oil injection component has right-angle elbows at both ends. One end connects to the outdoor oil injection unit via connector 27, and the other end is fitted with a compression fitting right-angle connector to the oil injection hole. This structure enables long-distance oil injection operations, overcoming the inconvenience of requiring manual on-site construction with current technology.

[0049] To ensure safety and ease of operation in the field, the outdoor oil filling unit of the present invention includes an oil tank 1, a housing, and a control board 21. The housing includes a top cover 2, which is connected to the oil tank 1 by a hinge 9 and a hinge flat washer 10. The upper perimeter of the oil tank 1 and the lower perimeter of the top cover 2 are respectively sealed with an oil tank sealing gasket 31 and a hollow rubber plug 7 for sealing the upper and lower covers. The control board 21 is fixed to the housing by mounting screws 29.

[0050] The electronic actuator 3 and the hydraulic cylinder assembly 22 are fixed to the control board 21 by screws. The electronic actuator 3 is connected to the control board 21 by the adjusting bracket 6, the pin 24 and the shaft retainer 25. The electrical control box 5 is fixed to the control board 21 by screws and is electrically connected to the electronic actuator 3. One end of the Rc1 / 4 check valve 23 is connected to the left and right hydraulic cylinders 26, and the other end is connected to the Rc elbow 28 to form a passage. Then, an oil pipe is connected to it, which extends out of the oil tank to form an oil outlet.

[0051] The adjustment bracket 6 is fixed to the control board 21 by M5×10 screws to position the electronic push rod 3. The foldable handle 8 is installed and fixed to the side of the oil tank top cover 2 by M10 screws. The cryogenic solenoid valve 11 is fixed to the control board 21. The inlet of the cryogenic solenoid valve 11 is connected to the outlet of the oil cylinder assembly 22 through the reducing joint 19.

[0052] The inlet of the output oil pipe assembly 16 is connected to the outlet of the cryogenic solenoid valve 11 via a reducing connector 19. The outlet of the output oil pipe assembly 16 passes through the oil pipe protective box 12 and is connected to an external high-pressure hose via a quick-connect connector 18. The oil pipe protective box 12 is fixed to the side of the oil tank 1 with M4×8 screws, which protects and guides the outlet oil pipe.

[0053] One end of the oil inlet pipe 15 is connected to the bottom of the oil tank 1, and the other end is connected to the inlet of the oil cylinder assembly 22 through the reducing joint 19 to form an oil suction passage.

[0054] The oil pipe protective box 12 is fixed to the side of the oil tank 1 via an M4×8 connection. The nitrile rubber sealing gasket 13 is glued to the groove of the oil tank 1 cover with single-sided adhesive. The diverter plate 14 is installed and fixed to the control plate 21 with M5×8 screws. The diverter plate 14 is connected to the quick-connect coupling 18. The oil inlet pipe 15 is fixedly connected to the reducer 19 to form a passage. The oil outlet pipe assembly 16 is connected to the cryogenic solenoid valve 11 via the reducer 19 to form a passage, leading to the outside of the tank for oil filling. The elbow 17 connects the cylinder assembly 22 to the oil supply pipe to form a passage. The quick-connect coupling 18 is connected to the oil supply pipe and fixedly connected to the diverter plate 14 to form a passage. The oil plug 20 seals the cylinder assembly 22 by twisting the thread, which serves to vent air.

[0055] Inside the box, the wire harness and oil pipe are fixed and organized by stainless steel clips 4.

[0056] The automatic oil injection lubrication of this invention can achieve the following automatic oil injection functions:

[0057] 1. It has an intelligent oil lubrication function for each set of turnout external locking devices, see Figure 9On the main interface of the gap monitoring system, select "Switch Machine Monitoring Parameter Modification". On the parameter modification interface, select "Lubrication Settings" and enter "Number of Operations", "Lubrication Cycle", and "Lubrication Amount". Based on the count of the turnout in the positioning or reverse position information monitored by the system, if the lubrication interval of the turnout in positioning or reverse position exceeds the lubrication cycle, or if the number of operations from the turnout to positioning or reverse position exceeds the set number of operations, the system will intelligently lubricate once. After lubrication, the lubrication interval count and the number of operations are both reset to zero and counted again.

[0058] 2. Each outdoor lubrication unit has two lubrication points: one on the positioning locking surface and one on the reverse locking surface. In addition to lubrication, these points also provide some protection. Additional lubrication points can be added as needed.

[0059] 3. Manual oiling function: It has a manual oiling function in both indoor and outdoor sites.

[0060] Manual oil filling in the room: See Figure 10 On the main interface of the gap monitoring system, select "Manual Oiling". There is an "Oiling" button on the manual oiling interface. Click the "Oiling" button and the system will issue an immediate oiling instruction. It will no longer judge the interval time and the number of operations, but only judge the fixed and reverse positions, and oil the switch in the fixed or reverse position according to the switch position information.

[0061] Manual oiling on site: See Figure 11 After opening the top cover 2 of the outdoor oil filling unit, you can see the buttons on the electrical control box 5, which include "full oil setting", "positioning manual oil filling", and "reverse position manual oil filling".

[0062] The functions of the buttons mentioned above are as follows: After oil tank 1 is filled with oil, the oil level gauge of oil tank 1 displays the full oil level. At this time, click the "Full Oil Setting" button to send the full oil information to the monitoring host.

[0063] B "Positioning Manual Oil Injection" and "Reverse Positioning Manual Oil Injection" – each click injects 0.1 mL of oil, while a long press allows for continuous oil injection.

[0064] 4. Data Query: Historical data can be queried for each oil injection time, location, and cumulative number of oil injections. See [link / reference]. Figure 9 .

[0065] 5. Alarm function: The system receives oil level information sent from the outdoor oil filling unit. When the oil level is lower than the pre-alarm value, it issues a low oil level pre-alarm.

[0066] The automatic lubrication is achieved by communicating with the environmental detection module 32 and the switch machine to collect environmental data and the number of turnout operations in real time;

[0067] Based on the environmental data and the number of turnout operations, the monitoring host queries the pre-stored strategy mapping table locally and autonomously generates an oil injection command.

[0068] The process of issuing the oil injection command to the outdoor oil injection unit and controlling it to perform the oil injection operation, based on environmental data and a query strategy mapping table, specifically includes:

[0069] Adjust the basic oil injection cycle based on real-time collected temperature and humidity data;

[0070] When rain and snow detection information indicates that there is rain or snow, an instruction to shorten the oiling cycle is generated; when wind and sand detection information indicates that the wind speed or dust concentration exceeds the threshold, an instruction to immediately execute oiling or increase the amount of oil injected at one time is generated.

[0071] The oil injection strategy mapping table includes a multi-parameter coupling strategy:

[0072] In high temperature and high humidity environments, a strategy of shortening the oil injection cycle and reducing the amount of oil injected at one time is adopted;

[0073] In low-temperature and dry environments, a strategy of extending the oiling cycle while maintaining the standard oiling volume is adopted;

[0074] After rain or snow, disregard cycle restrictions and immediately perform an enhanced oil injection;

[0075] During periods of persistent sandstorms, a strategy of periodically doubling the amount of fuel injected is adopted.

[0076] Furthermore, the present invention also includes an environmental trend prediction refueling step: the system continuously records the trend of environmental data changes; if severe weather such as rain, snow, or strong winds is predicted to occur, preventive refueling is performed in advance before the weather event occurs.

[0077] The step of autonomously generating the lubrication command also includes: calculating the lubrication demand index by combining the turnout operation frequency and the environmental corrosion level; and dynamically adjusting the parameters in the lubrication strategy table according to the lubrication demand index to achieve adaptive learning and optimization. Example 2

[0078] like Figure 5 , Figure 6 , Figure 7 As shown, the structure of Embodiment 2 is exactly the same as that of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the oil tank 1 is led to the two oil cylinder assemblies through two oil inlet pipes, and the two reducing joints 19 are connected by an Rc1 / 4 check valve 23.

[0079] In this invention, the electronic control box 5 is equipped with: a full oil setting button, used to send a full oil signal to the monitoring host after the oil tank 1 is filled; a positioning manual oil filling button; and a reverse manual oil filling button. The buttons support inching oil filling and long-press continuous oil filling, and are located on the operation panel of the electronic control box 5 for easy on-site operation.

[0080] In this invention, the monitoring host and the intelligent oil injector are connected by a pair of cables using carrier communication for power supply and data transmission, thereby achieving co-line transmission of power and signals.

[0081] Furthermore, in this invention, the software operation interface of the monitoring host integrates a manual oil injection control unit, an oil injection parameter setting unit, an oil injection history query unit, and an alarm information display unit. The oil injection history query unit records oil injection data including oil injection time, oil injection location, oil injection volume, and environmental data when oil injection is triggered.

[0082] The system workflow of this invention is as follows: Figure 8 As shown, the power supply and initial state are as follows: The indoor monitoring host provides 220Vac power to the outdoor oil injection unit through a pair of through cables and establishes carrier communication. After the equipment is powered on, the monitoring host and the gap monitoring system share the carrier communication to continuously monitor the status of the outdoor oil injection unit via cable, including oil level signals, environmental sensor data such as temperature and humidity, and receive turnout positioning / reversal information and operation count information from the switch machine.

[0083] like Figure 9 As shown, this invention uses intelligent oil injection triggering for judgment: the oil injection control module in the monitoring host makes real-time judgments based on a preset algorithm. Users can access "Oil Injection Settings" through the monitoring system software interface to preset parameters such as "Number of Operations," "Oil Injection Cycle," and "Single Oil Injection Amount." The module integrates these parameters with real-time environmental data, and generates an oil injection command when any of the following conditions are met: Condition A: Cycle Trigger: The set "Oil Injection Cycle" has been reached since the last oil injection.

[0084] Condition B Action Count Triggered: The number of times the turnout has been manipulated to a certain position or reversed has reached the set "number of operations".

[0085] Condition C: Environmental strategy triggered: Based on the built-in strategy table, current environmental data such as strong winds and dust storms, post-rain conditions, and high temperature indicators require adjustment of the fuel injection strategy.

[0086] Oil injection command execution: The monitoring host sends an oil injection command to the electrical control box 5 of the outdoor oil injection unit via cable. The command includes the oil injection amount and the target position is set or reversed by controlling the oil injection time.

[0087] After receiving the instruction, the electronic control box 5 first controls the opening of the low-temperature solenoid valve 11 of the corresponding oil circuit or drives the electronic push rod 3 to push the 26 of the corresponding side oil cylinder in embodiment two. Then, the electronic control box 5 drives the electronic push rod 3 to move for a predetermined time, pushing the plunger 30 in the oil cylinder assembly 22, and accurately injecting a predetermined amount of lubricating oil through the output oil pipe assembly 16 and the high-pressure hose into the oil injection component that is positioned or reversed at the designated position.

[0088] like Figure 10 , Figure 11 and Figure 12 As shown: The manual oiling mode is as follows: Figure 10 As shown, remote manual operation: staff can monitor the host computer's software interface. Figure 10 Click the "Manual Oiling" button to force the equipment to perform an immediate oiling operation. The system will only oil the corresponding side after determining the position of the turnout.

[0089] like Figure 11 Local manual operation as shown: After opening the top cover 2 of the oil tank, you can directly operate the "positioning manual oil filling" or "reverse manual oil filling" button on the electronic control box 5. One press adds 0.1mL of oil, and a long press adds oil continuously. After filling is complete, you can click the "full oil setting" button to send a full oil signal to the main unit.

[0090] like Figure 12 The data recording and querying shown includes: the time, location, amount of oil injected, and environmental data triggered by each oil injection operation are recorded and stored in the monitoring host. Users can query historical oil injection records through the "Oil Injection Details Query" menu in the software interface.

[0091] Oil level alarm: When the oil level sensor in the outdoor oil filling unit detects that the lubricating oil level is lower than the preset alarm value, it will send an alarm message to the monitoring host and prompt the staff to add lubricating oil in time through the software interface.

[0092] The system principle of this invention is as follows: The indoor main unit is connected to the cable box next to the outdoor switch machine by a pair of through wires, and the outdoor cable box is connected to the outdoor oil injection unit on the standardized work platform next to the switch machine by a pair of cables, so that the outdoor oil injection unit is powered by a 220Vac power input.

[0093] Select the oil injection function key in the monitoring host software to bring up the oil injection interface. You can set the single oil injection volume, oil injection interval time, and number of operations. Combined with the turnout position information determined by the system, intelligent oil injection can be achieved.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any changes, substitutions or improvements made to the structure and features described in the scope of the present invention should be included within the protection scope of the present invention.
