Description

Technical Field

[0001] This application relates to the field of automatic control technology for railway freight cars, and in particular to an automatic gate control system and control method for mixed freight trains. Background Technology

[0002] Railways are a vital national infrastructure and the backbone of the transportation system, boasting advantages such as large capacity, low cost, and energy efficiency. As a crucial transport vehicle, railway freight cars have evolved into mixed-cargo trains to accommodate diverse cargo transport requirements. As the name suggests, mixed-cargo trains consist of multiple carriages of different models and materials, thus requiring differentiated loading and unloading gate control operations.

[0003] To meet the loading and unloading gate control requirements of single-train mixed freight trains, existing technologies generally use manual operation to open the gates after the train stops, which cannot achieve differentiated gate control for loading and unloading without stopping the train. Summary of the Invention

[0004] To address or partially address the technical problem of existing technologies' inability to achieve differentiated gate control for loading and unloading without train stopping, this invention provides an automatic gate control system and method for mixed freight trains. By deploying trackside gate control equipment alongside the railway, when a mixed freight train passes these devices, the system communicates with the train to obtain the numbers of the carriages to be loaded or unloaded, matches the carriages, and then supplies power to the gate control devices of the carriages to control the opening of their doors. This allows for wireless communication with the train and automatic door opening without the train stopping, enabling loading and unloading operations to be completed without stopping. Furthermore, gate control can be implemented for different types of differentiated carriages, meeting the differentiated gate control requirements and fully unmanned control requirements of mixed freight trains. The entire operation is fully unmanned, efficient, safe, and reliable. The equipment is highly modular and intelligent, easy to maintain and deploy.

[0005] To address the aforementioned technical problems, a first aspect of the present invention discloses an automatic gate control system for mixed freight trains, the automatic gate control system comprising:

[0015] The mounting base is fixed to the outside of the carriage and is insulated;

[0016] The plurality of electrically charged impact plates are arranged vertically at intervals in the mounting base. Each electrically charged impact plate is electrically connected to a door control mechanism for controlling the opening and closing of the corresponding door, and each electrically charged impact plate is in contact with its corresponding elastic power supply element to receive power.

[0017] A second aspect of the present invention discloses a control method for an automatic gate control system for a mixed freight train as described in the first aspect, comprising:

[0018] When the communication of the mixed freight train enters the communication range of the trackside gate control equipment, the trackside gate control equipment communicates with the mixed freight train to obtain the loading and unloading gate control information of the mixed freight train; wherein, the loading and unloading gate control information includes at least the number of the car to be loaded or unloaded; wherein, the car to be loaded or unloaded with different numbers is powered by different combinations of flexible power supply elements.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0044] Firstly, such as Figures 1-3 As shown, the automatic door control system for mixed freight trains provided in this embodiment of the invention is applicable to the control scenario of automatic opening and closing of doors (such as different models or different positions) for loading and unloading of mixed freight trains.

[0045] The automatic gate control system of this invention includes: a mixed freight train 10 and a trackside gate control device 20. The mixed freight train 10 runs on the track, and the trackside gate control device 20 is arranged beside the railway. One trackside gate control device 20 is installed on each track, but this does not constitute a restriction. When the mixed freight train 10 passes by, the trackside gate control device 20 automatically controls the gate operation, enabling the mixed freight train 10 to handle the differentiated loading and unloading gate operation needs of each car without stopping. It performs gate control operations on cars with differentiated loading and unloading needs, allowing the train to complete differentiated loading and unloading operations without stopping, thus improving train operating efficiency.

[0046] The mixed-model freight train 10 includes a locomotive control room and a mix of different types of carriages. Each carriage differs in one or more aspects such as model, material, and size, therefore the loading and unloading requirements of each carriage may also differ. In this embodiment of the invention, the differentiated loading and unloading access control requirements of each carriage are represented by carriage numbers. Once the carriage number is obtained, the differentiated loading and unloading access control requirements of each carriage can be determined, thus distinguishing it from other carriages.

[0047] Each carriage is equipped with a door control power receiving device 101 for controlling the opening of the carriage doors. Specifically, each carriage is equipped with a carriage door control mechanism electrically connected to the door control power receiving device 101. The carriage door control mechanism is mainly used to control the opening of the carriage doors. The door control power receiving device 101 supplies power to the carriage door control mechanism so that the carriage door control mechanism can control the opening of the carriage doors. The carriage doors of each carriage can be top doors, side doors, or bottom doors, but this is not a limitation. To accommodate the differentiated designs of different carriage models, the carriage door control mechanisms inside each carriage can also be different, but this is not a limitation. For example, the carriage door control mechanism includes an electrically controlled cylinder structure and a solenoid valve. The solenoid valve can energize and de-energize the electrically controlled cylinder structure, thereby controlling the opening and closing of the carriage door. When the door control power receiving device 101 is energized, the solenoid valve is energized and opens, causing the electrically controlled cylinder structure to operate and drive the carriage door to open, so as to perform loading and unloading operations. When the door control power receiving device 101 loses power and the solenoid valve closes, the electric control cylinder structure stops working and the door closes automatically.

[0048] See Figure 3 This is a schematic diagram of the structure of the gate control power receiving device 101, including: a mounting base 1011 and several power receiving impact plates 1012 disposed on the mounting base 1011. The mounting base 1011 is fixed to the outside of the vehicle body and is insulated. For example, the mounting base 1011 is made of insulating materials such as wood, plastic, or rubber to prevent current from entering the mounting base 1011 and causing a leakage accident.

[0049] A plurality of electrically charged impact plates 1012 are arranged vertically at intervals in the mounting base 1011. Each electrically charged impact plate 1012 is electrically connected to a door control mechanism for controlling the opening and closing of a corresponding door, and each electrically charged impact plate 1012 is in contact with its corresponding elastic power supply element 202 to receive electricity. Furthermore, the plurality of electrically charged impact plates 1012 and the plurality of elastic power supply elements 202 correspond one-to-one. Based on this, the plurality of elastic power supply elements 202 are also arranged vertically at intervals and adapted to the height of their respective electrically charged impact plates 1012.

[0050] Specifically, when the mixed freight train 10 passes the trackside gate control equipment 20, electrical connection is achieved through contact between the electric shock plates 1012 and the elastic power supply elements 202 in each car. Since the mixed freight train 10 continues to move during charging, the electric shock plates 1012 and the conductive elastic power supply elements 202 will rub against each other. Over time, scratches from the elastic power supply elements 202 will appear on the electric shock plates 1012. Therefore, the electric shock plates 1012 need to be made of conductive materials with sufficient strength to extend their service life. For example, the electric shock plates 1012 can be made of steel, which is conductive and can ensure a certain level of strength.

[0051] exist Figure 3 In this design, the mounting base 1011 is a T-shaped base, with its bottom surface fixed to the outside of the carriage. The T-shaped surface of the base is insulated, and several electric shock plates 1012 are vertically spaced and embedded in the T-shaped surface. Due to the insulation of the T-shaped surface, the electric shock plates 1012 are not electrically conductive to each other. Each electric shock plate 1012 is electrically connected to the carriage door control mechanism via a wire 1013 passing through the mounting base 1011. Figure 3 The structures shown are for illustrative purposes only and do not constitute a limitation.

[0052] It is worth noting that, due to the differentiated characteristics of each carriage, different models of carriages correspond to different combinations of energized impact plates 1012. Combining the one-to-one design of several energized impact plates 1012 and several flexible power supply elements 202, carriages with different numbers are powered through different combinations of flexible power supply elements. The differentiated power supply operation will be explained later and will not be repeated here.

[0053] The trackside gate control device 20, located beside the railway, includes: a base 201, a power supply mechanism (e.g., a flexible power supply element 202) movably mounted on the base 201, and a control component 203 connected to the power supply mechanism. Through the trackside gate control device 20 installed beside the track, it can communicate with the upcoming mixed freight train 10 to obtain its loading and unloading control requirements in advance. When each car of the mixed freight train 10 passes the trackside gate control device 20, the car number is obtained and verified using radio frequency identification (RFID) technology. Upon verification of a car requiring loading and unloading, the power supply mechanism is automatically activated, connecting to the gate control power receiving device 101 of the car to be loaded or unloaded, thereby controlling the automatic opening and closing of the corresponding door. After the mixed freight train 10 departs, the power supply mechanism of the trackside gate control device 20 moves to a standby position outside the track clearance, awaiting the arrival of the next freight train.

[0054] The power supply mechanism has a standby working position and a power supply working position on the base 201. The power supply mechanism is initially located in the standby working position; the standby working position is the position where the power supply mechanism is parallel to the railway, located outside the track clearance, and will not interfere with the normal operation of the railway; the power supply working position is the position where the power supply mechanism is perpendicular to the railway. In response to the loading and unloading gate control requirements of passing carriages to be loaded or unloaded, and given the adaptability of the power supply mechanism on the base 201, the power supply mechanism can switch from the standby working position to the power supply working position, connect to the gate control power receiving device 101 of the carriage to be loaded or unloaded, and supply power to it.

[0055] The power supply mechanism includes several flexible power supply elements 202, and different carriages correspond to different combinations of flexible power supply elements 202 to provide power. During the process of contact between the flexible power supply elements 202 and the door control power receiving device 101, deformation will occur. The sensors on the flexible power supply elements 202 collect the deformation, indicating that the contact connection has been successfully established and the power supply conditions are met.

[0056] The control component 203 has the ability to acquire data from multiple sensors, has input / output operation capabilities, can drive motor-type loads and control the moving mechanism 2012, and has remote communication capabilities. Of course, it also has human-machine interaction functions.

[0057] Specifically, the control component 203 is used to communicate with the mixed freight train 10 to obtain the loading and unloading gate control information of the mixed freight train 10; wherein, the loading and unloading gate control information includes at least the number of the car to be loaded or unloaded; when the mixed freight train 10 passes through the trackside gate control equipment 20, the car to be loaded or unloaded is matched based on the number of the car to be loaded or unloaded, the power supply mechanism is controlled to operate and connect to the gate control power receiving device 101 of the car to be loaded or unloaded, and the corresponding flexible power supply element 202 is controlled to supply power to the gate control power receiving device 101 of the car to be loaded or unloaded, so as to cause the door of the car to be loaded or unloaded to open and perform loading and unloading operations.

[0058] Since the mixed freight train 10 is in motion, after the current carriage passes the trackside gate control equipment 20, it will disconnect from the power supply mechanism, and the power supply mechanism will be connected by the gate control power receiving device 101 of the next carriage. Therefore, all carriages will be connected to the power supply mechanism when passing the trackside gate control equipment 20.

[0059] Based on this, when the power supply mechanism moves to the power supply working position, it can connect to all the carriages in sequence. When connecting to the carriage to be loaded or unloaded, it is only necessary to control the corresponding flexible power supply element 202 to supply power according to the carriage number to be loaded or unloaded. Once the carriage to be loaded or unloaded leaves the trackside gate control equipment 20, it can disengage and withdraw the power supply mechanism.

[0060] As an optional implementation, the base 201 includes: a supporting main frame 2011, a movable mechanism 2012, and a mounting bracket 2013.

[0061] The main support frame 2011 is fixed to the side of the railway, for example, to the ground beside the railway. The movable mechanism 2012 is movably mounted on top of the main support frame, and a mounting bracket 2013 connects to the movable mechanism 2012 and assembles the power supply mechanism therein. The power supply mechanism, driven by the movable mechanism 2012, is connected to the gate control power receiving device 101.

[0062] Specifically, the main support frame 2011 includes a base and a support rod installed on the base. The base is fixed to the ground, and the movable mechanism 2012 is movably set at the top of the support rod.

[0063] The main function of the movable mechanism 2012 is to drive the power supply mechanism and connect it to the gate control power receiving device 101. In practical applications, the movable mechanism 2012 includes, but is not limited to, telescopic supports, rotating supports, and folding supports, which drive the power supply mechanism to move through telescopic, rotating, and folding mechanisms. Taking the rotating support as an example, when the mixed freight train 10 has not entered the working area, it keeps the elastic power supply element 202 out of the track clearance range and in the standby working position. When the mixed freight train 10 passes by, it drives the elastic power supply element 202 to rotate to the power supply working position.

[0064] The advantage of setting up the movable mechanism 2012 is that it enables the trackside gate control device 20 to ignore distance differences and connect to the corresponding gate control power receiving device 101 for power supply. For example, due to the differentiated layout of different platforms, the relative distance between the trackside gate control device 20 and the mixed freight train 10 may vary at different platforms. The movable mechanism 2012 enables the trackside gate control device 20 to ignore distance differences and successfully connect to and power the gate control power receiving device 101 of the mixed freight train 10. As another example, due to the different models of the cars in the mixed freight train 10, the relative distance between the trackside gate control device 20 and each car in the mixed freight train 10 may also vary. The movable mechanism 2012 enables the trackside gate control device 20 to ignore the distance differences with the cars, thereby successfully connecting to and powering the gate control power receiving device 101 of the car to be loaded or unloaded.

[0065] Since the power supply mechanism includes several flexible power supply elements 202, these elements are also vertically spaced in the mounting bracket 2013 and are adapted to the height of their respective electric impact plates 1012. It is worth noting that when the carriages to be assembled pass through, all the flexible power supply elements 202 in the power supply mechanism are connected to all the electric impact plates 1012 in the door control power receiving device 101 of the carriages to be loaded / unloaded; then, according to the carriage number, the corresponding flexible power supply element 202 is controlled to supply power to the door control power receiving device 101 of the carriages to be loaded / unloaded. For example, each flexible power supply element 202 in the power supply mechanism has a number, from top to bottom: A, B, C… There are two carriages to be loaded / unloaded in the mixed freight train 10, numbered 2 and 3, indicating that both the second and third carriages to be loaded / unloaded have assembly requirements. Since the number not only indicates the position of the carriage in the mixed freight train 10 but also the carriage model,… Once the car door number is identified, it can be determined that this car is different from other cars. Therefore, when car 2 (to be loaded / unloaded) passes by the trackside door control equipment 20, the flexible power supply elements 202 (numbered A and B) supply power to the door control power receiving device 101 of car 2. Similarly, when car 3 (to be loaded / unloaded) passes by the trackside door control equipment 20, the flexible power supply elements 202 (numbered B and C) supply power to the door control power receiving device 101 of car 3.

[0066] As an optional implementation, the control component 203 includes a near-field communication unit, such as an ISM band such as 433M, a WIFI communication unit, etc., for near-field communication with the mixed freight train 10 to obtain loading and unloading gate control information.

[0067] As an optional implementation, the trackside gate control device 20 further includes an RFID reader 204 mounted on a base 201. Each car of the mixed freight train 10 is equipped with a car number electronic tag 1014. For example, the car number electronic tag 1014 can be mounted in the gate control power receiving device 101, specifically on the mounting base 1011 of the gate control power receiving device 101. The RFID reader 204 is used to identify the car number electronic tags 1014 mounted on the passing cars when the mixed freight train 10 passes through the trackside gate control device 20; and to match the cars to be loaded or unloaded by comparing the car number to be loaded or unloaded with the car number electronic tag 1014.

[0068] The solution in this embodiment of the invention obtains loading and unloading gate control requirements in advance through near-field communication with mixed freight trains. By recognizing the carriages, independent control of the opening and closing of gates in different carriages is achieved, enabling unmanned loading and unloading operations without stopping the mixed freight trains. The operation is efficient, safe, and highly intelligent, thus addressing the differentiated loading and unloading gate control requirements of mixed freight trains in commutation transport scenarios.

[0069] Based on the same inventive concept, embodiments of the present invention also provide a control method for an automatic gate control system of a mixed freight train 10 as described in the first aspect, see below. Figure 4 ,include:

[0070] S401, when the mixed freight train 10 enters the communication range of the trackside gate control device 20, the trackside gate control device 20 communicates with the mixed freight train 10 to obtain the loading and unloading gate control information of the mixed freight train 10.

[0071] Specifically, after the trackside gate control device 20 in the automatic gate control system is installed, it performs a power-on self-test, automatically detecting signals from various position sensors, contacts of the elastic electrodes, etc., to ensure a normal initial state. After the self-test is complete, the power supply mechanism is controlled to enter the standby working position, and the current position status is displayed through status indicator lights. The trackside gate control device 20 activates its near-field communication module (e.g., WIFI) and waits for train communication connection. When the mixed freight train 10 approaches the trackside gate control device 20, communication is established between the two. The trackside gate control device 20 receives loading and unloading gate control information and controls the power supply mechanism to rotate from the standby working position to the power supply working position, outputting a positioning signal when it reaches the correct position. The power supply mechanism is initially in the standby working position; the standby working position is the position where the power supply mechanism is parallel to the railway; the power supply working position is the position where the power supply mechanism is perpendicular to the railway. If communication with the mixed freight train 10 is not established, it continues to wait.

[0072] The loading and unloading gate control information includes at least the car number to be loaded or unloaded, such as number 2 and number 3, indicating that both the second and third cars to be loaded or unloaded have assembly requirements. The differentiated characteristics of each car (such as model and type) are reflected using the car number. Cars with different numbers are powered by different combinations of flexible power supply components.

[0073] S402, when the mixed freight train 10 passes through the trackside gate control equipment 20, the trackside gate control equipment 20 matches the car to be loaded or unloaded based on the car number, controls the internal power supply mechanism to operate and connects it to the door control power receiving device 101 of the car to be loaded or unloaded, and controls the flexible power supply element 202 in the power supply mechanism that matches the car to be loaded or unloaded to supply power to the door control power receiving device 101 of the car to be loaded or unloaded, so as to open the car door of the car to be loaded or unloaded and perform loading and unloading operations.

[0074] Specifically, when the mixed freight train 10 passes through the trackside gate control equipment 20, each carriage will pass through the trackside gate control equipment 20 one by one. At this time, the trackside gate control equipment 20 identifies the carriage number electronic tag 1014 installed on the passing carriage. It compares whether the carriage number electronic tag 1014 is among the carriage numbers to be loaded or unloaded; if so, it determines the carriage to be loaded or unloaded based on the carriage number electronic tag 1014, that is, it determines that the currently passing carriage is the carriage to be loaded.

[0075] When a car body to be loaded or unloaded is matched, the power supply mechanism is moved from the standby position to the power supply position, and it is determined whether the power supply mechanism is in contact with the door control power receiving device 101. If so, the power supply mechanism is energized.

[0076] Specifically, when the power supply mechanism contacts the gate control receiving device 101, it indicates that the charging conditions have been met. Therefore, the power supply mechanism is energized to connect with the gate control receiving device 101. Furthermore, when the power supply mechanism contacts the gate control receiving device 101 of the car to be loaded / unloaded, all the elastic power supply elements 202 in the power supply mechanism contact and connect with all the energized impact plates 1012 in the gate control receiving device 101, generating friction as the car to be loaded / unloaded moves. If deformation is detected in the elastic power supply elements 202, it indicates that the charging conditions have been met. If the power supply mechanism does not contact the gate control receiving device 101, it indicates that the gate control receiving device 101 has not yet reached the trackside gate control equipment 20.

[0077] Different types of wagons to be loaded / unloaded have their own corresponding flexible power supply elements 202 for power supply. For ease of control, each flexible power supply element 202 is numbered, and different types of wagons to be loaded / unloaded correspond to their respective flexible power supply element 202 number combinations. During the power supply control process, based on the wagon number to be loaded / unloaded, the matching number combination is determined; according to the matching number combination, the corresponding flexible power supply element 202 is controlled to supply power to the door control receiving device 101 of the wagon to be loaded / unloaded.

[0078] For example, the car to be loaded / unloaded, numbered 2, corresponds to the flexible power supply element 202 number combination AB, and the car to be loaded / unloaded, numbered 3, corresponds to the flexible power supply element 202 number combination BC. During control, when the car to be loaded / unloaded, numbered 2, passes the trackside gate control equipment 20, the flexible power supply elements 202 numbered A and B are controlled to supply power to the gate control power receiving device 101 of the car to be loaded / unloaded, and its door performs the corresponding response action. After the car to be loaded / unloaded, numbered 2, the flexible power supply element 202 is de-energized and waits for the next car to enter. When the car to be loaded / unloaded, numbered 3, passes the trackside gate control equipment 20, the flexible power supply elements 202 numbered B and C are controlled to supply power to the gate control power receiving device 101 of the car to be loaded / unloaded, and its door performs the corresponding response action. Gate control operations are performed on all cars to be loaded / unloaded in the above manner until the mixed freight train 10 has completely departed.

[0079] Specifically, it determines in real time whether the power supply mechanism is disconnected from the gate control power receiving device 101. For example, deformation is used to determine whether the connection is lost. If the elastic power supply element 202 has no deformation, it indicates that the power supply mechanism is disconnected from the gate control power receiving device 101. If disconnected, the power supply mechanism is de-energized to avoid causing a leakage accident.

[0080] After the mixed freight train 10 departs, the trackside gate control equipment 20 returns to the standby working position, waiting for the next train to arrive.

[0081] The present invention provides a solution by arranging trackside gate control equipment beside the railway. When a mixed freight train passes through the trackside gate control equipment, the loading and unloading gate control requirements of each carriage of the mixed freight train can be obtained in advance through communication with the mixed freight train. Then, power is supplied to the gate control power receiving device of the carriage to control the opening of the carriage door. This enables wireless communication with the train and automatic door opening without stopping the train, allowing the train to complete loading and unloading operations without stopping. It also enables independent power supply control for different carriages of the same train, and can be used efficiently, safely and reliably for the door opening and closing control of different types of carriages in mixed freight trains.

[0082] In addition, door control can be implemented for different models of differentiated carriages, meeting the differentiated door control requirements and fully unmanned control requirements of mixed freight trains. The entire operation process can achieve fully unmanned control, high efficiency, safety and reliability. The equipment is highly modular and intelligent, and easy to maintain and deploy.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0084] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
