Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of railroad guardrail machines, and in particular to a railroad guardrail machine controller and a control method. Background Art

[0002] Railway-specific railings are used at level crossings between railways and highways to intercept vehicles and pedestrians on the road.

[0003] The existing railway-specific wood barrier machine has no controller. The start and stop of its motor and brake need to be driven by a dedicated control box containing complex logic circuits. The existing control box contains complex circuit components and uses a large number of relays, terminals, circuit breakers, power supplies and other components. It is relatively large and cannot be deeply integrated with the wood barrier machine. The wood barrier machine and the control box require a large number of wire harnesses for electrical connection. The wood barrier machine itself cannot be started and stopped, cannot be remotely controlled, cannot communicate with the host computer, and has no self-protection function. In addition, the wood barrier machine generally uses gear transmission to the cam and physical mechanical touch travel switch to realize angle detection. Its mechanical structure is complex, the angle adjustment is difficult and the failure rate is high.

[0004] Therefore, the present invention provides a railway-specific wood barrier controller and control method, aiming to solve these problems. The controller adopts a board control circuit, a built-in logic main control chip and embedded software, is compact and exquisite, and is customized according to the internal structure of the wood barrier. It is installed inside the wood barrier and fits perfectly with the wood barrier chassis, occupying a small space. The controller directly drives the wood barrier motor and brake to achieve forward and reverse rotation of the motor. The controller uses a Hall sensor to detect the angle of the wood barrier rotating shaft, stop the motor in place and lock the motor brake. The controller has a wireless remote control and communication module, and its embedded software is equipped with control protection logic. Summary of the invention

[0005] The embodiment of the present invention relates to a railway special wood barrier controller and control method, specifically an integrated control device for improving the functionality, reliability and operation convenience of the railway special wood barrier. The controller is intended to solve the problems existing in the prior art such as complex assembly, difficult angle adjustment, high failure rate, and single function.

[0006] To achieve the above purpose, the present application provides a railway special railroad fence machine controller and control method, and the technical solution adopted is:

[0007] In the first aspect, a railway-specific wood barrier machine controller is provided, wherein the control main board is used to process control signals and execute control logic, the control main board is placed on a control board bottom shell and fixed to a wood barrier machine case, the control board bottom shell passes through the tail of the wood barrier machine main shaft and is fixed, thereby ensuring the stability and reliability of the control main board during equipment operation.

[0008] Preferably, the angle detection module is installed at the tail of the main shaft, and a Hall sensor is used. When the main shaft of the wood fence machine rotates, the position and direction of the magnet will change relative to the Hall sensor, causing the magnetic field strength and direction detected by the Hall sensor to change. This change can detect the rotation angle of the main shaft of the wood fence machine. Reduce the failure rate of angle detection and ensure the accuracy of the motor stopping in place and locking the motor brake.

[0009] Preferably, the control board bottom shell is used to fix the control main board, and the cover plate is used to protect the control main board and its internal components.

[0010] Preferably, the capacitor is installed in the fence chassis to stabilize the working voltage of the motor and prevent voltage fluctuations from affecting the motor performance, thereby improving the stability of the equipment.

[0011] Preferably, the switching power supply provides the power required by the controller to ensure the normal operation of the controller.

[0012] Preferably, the above-mentioned empty wiring terminals are used for electrical connection and protection to ensure the stability and reliability of the electrical connection.

[0013] Preferably, the above-mentioned controller is provided with a dial switch, and the two coils in the fence machine motor are coils with different pole pairs to achieve different rotation speeds, ensuring that the fence of the fence machine rises faster and falls slower; the installation on the left side of the fence machine is different from that on the right side, so the two coils need to be driven in reverse; when the fence machine is installed on the left side, coil A drives it to rise and coil B drives it to fall; when the fence machine is installed on the right side, coil A needs to rotate in the opposite direction to drive it to rise, and coil B needs to rotate in the opposite direction to drive it to rise. The controller circuit logic can be switched by the dial switch to change the driving direction of the two coils, so as to achieve fast rising and slow falling of the fence machine.

[0014] Preferably, the above-mentioned motor and brake are connected to a running component passing through the triangular bottom plate, and the running component includes a plurality of gears and a rotating shaft, which are used to drive the main shaft of the wood fence machine to rotate, and the motor can achieve overload protection.

At the same time, it can be linked with anti-smashing, ground sensing and other equipment for protection.

[0016] Preferably, the embedded software of the above-mentioned controller has built-in control protection logic to monitor the position of the motor in real time. When the motor completes the action and reaches the target position, the controller will send a signal to activate the brake.

[0019] S2. When the detection result shows that a train is about to pass, a command to close the crossing is sent through the controller module; at the same time, the detection unit detects whether there are stagnant vehicles or pedestrians in the crossing, and transmits the detection result to the barrier controller;

[0020] When the above detection result shows that there is no stationary vehicle or pedestrian, the motor brake is unlocked and the motor is driven to rotate, the barrier is lowered until it is fully in place and the light strip is lit;

[0021] When the above detection result is that there is a stagnant vehicle or pedestrian, the control module calculates the lowest height allowed for the vehicle or pedestrian to pass through the track, and obtains the initial rotation angle of the wood barrier at this height; the Hall sensor monitors the angle in real time, and sends a signal to control the motor to stop working when the angle is initially in place, and controls the wood barrier to rotate again after the vehicle or pedestrian passes until it is completely in place and the light strip is lit;

[0023] When the above detection result shows that there is no vehicle or pedestrian entering by mistake, the barrier machine works normally;

[0024] When the above detection result is that there is a vehicle or pedestrian who has strayed into the track, the control module calculates the minimum height at which the vehicle or pedestrian in the track is allowed to pass; if it needs to rise compared to the height of the barrier at this time, the controller controls the motor to reverse and control the barrier to rise to this angle; if it needs to fall compared to the height of the barrier at this time, the Hall sensor monitors the angle in real time. When it drops to this angle, the motor stops working and allows the vehicle or pedestrian who has strayed into the track to pass.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the embodiments of the present application easy to understand, the embodiments of the present invention are further described below in combination with diagrams and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0034] Example 1

[0035] For a better understanding of the embodiments of the present invention, please refer to Figure 1-3As shown, a railway special fence machine controller includes a fence machine case 1, a control main board 3, an angle detection module 6, a control board bottom shell 5, a drive device and a terminal 9. The fence machine case 1 is in a cubic shape, and its interior is hollow to form an installation cavity, and the above components are all installed in the installation cavity. The above control main board 3 is first fixed to the control board bottom shell 5, and then assembled into the fence machine case 1 as a whole, passing through the tail of the fence machine main shaft 4 and fixed. The control board bottom shell 5 is used to fix the control main board, and the cover plate is used to protect the control main board 3 and its internal components.

[0036] The angle detection module 6 is installed and fixed at the tail of the main shaft 4 of the wood fence machine. The Hall sensor is used. When the main shaft 4 of the wood fence machine rotates, the position and direction of the magnet relative to the Hall sensor will change, causing the magnetic field strength and direction detected by the Hall sensor to change. This change can detect the rotation angle of the main shaft of the wood fence machine. The failure rate of angle detection is reduced to ensure the accuracy of the motor stopping in place and locking the motor brake.

[0037] The above-mentioned driving device and terminal 9 are fixed in the fence machine case 1. The driving device includes a motor 2, a capacitor 7 and a switching power supply 8, which are installed in the fence machine case 1; the above-mentioned motor 2 is fixed on the triangular bottom plate 16 and is connected to the running parts passing through the triangular bottom plate 16.

[0038] The capacitor 7 is installed in the fence box to stabilize the working voltage of the motor, prevent the influence of voltage fluctuation on the motor performance, and improve the stability of the equipment. The switching power supply 8 provides the power required by the controller to ensure the normal operation of the controller. The terminal block 9 is used for electrical connection and protection to ensure the stability and reliability of the electrical connection.

[0039] The above controller is equipped with wireless remote control and communication modules. The wireless remote control module includes a remote control receiving unit and a control input unit; the communication module includes a 485 communication unit and a position signal output unit, which transmits data information and can realize the communication function between the fence machine and the host computer. The embedded software of the controller has built-in control protection logic to monitor the position of the motor in real time. When the motor completes the action and reaches the target position, the controller will send a signal to activate the brake. When the brake is working, the rotation of the motor is locked to prevent accidental movement.

[0040] The above-mentioned controller is provided with a dip switch, and the two coils in the wood fence motor are coils with different pole pairs to achieve different rotation speeds, ensuring that the fence of the wood fence rises faster and falls slower; the installation on the left side of the wood fence is different from that on the right side, so the two coils need to be driven in reverse; when the wood fence is installed on the left side, coil A drives it up and coil B drives it down; when the wood fence is installed on the right side, coil A needs to rotate in the opposite direction to drive it up, and coil B needs to rotate in the opposite direction to drive it up. The controller circuit logic can be switched through the dip switch to change the driving direction of the two coils, so as to achieve fast rising and slow falling of the wood fence.

[0041] As attached Figure 1 To Attachment Figure 3 When the fence controller of a specific embodiment of the present invention is working, the above-mentioned driving device is in use, and the control logic built in the control main board 3 controls the motor forward and reverse rotation through the interface; the motor can drive the small gear a17 to rotate, so as to drive the fence main shaft 4 to rotate; the small gear a17 is meshed with the large gear a12, and the large gear a12 is coaxially fixed with the small gear c19 through the rotating shaft b13, the small gear c19 is meshed with the large gear b14, and the small gear b18 is coaxially fixed with the large gear b14 through the rotating shaft a15, and the quarter-circular gear 11 meshes with the pinion b18. The quarter-circular gear 11 is fixed on the main shaft 4 of the wood barrier. When the motor is started, the pinion a17 rotates to drive the quarter-circular gear 11 to rotate, so that the main shaft 4 of the wood barrier rotates. The angle detection module 6 at the tail of the main shaft 4 of the wood barrier detects the deflection. If the rotation angle exceeds 90 degrees or the speed is too fast, the angle detection module 6 detects the fault and stops the motor and locks the motor brake to protect itself, thereby reducing the possibility of damage to the railing and the possibility of the railing losing its interception effect or even falling onto the railway and causing safety hazards.

[0042] Specifically, the angle detection module 6 includes a detection unit and a sensing unit. The Hall sensor can detect the rotation angle of the main shaft 4 of the wood barrier in real time, and can accurately determine the position of the wood barrier, and then determine whether the operation state of the wood barrier is normal, so as to reduce the possibility of accidents of the wood barrier. In this embodiment, after detecting the rotation angle of the main shaft 4 of the wood barrier, the angle detection module 6 can generate corresponding position information to indicate the position of the wood barrier. When it indicates that the wood barrier is in the interception position or the release position, a stop signal can be generated to control the motor to stop running and lock the brake.

[0043] Embodiment 2, a control method for a railway special railroad fence machine, comprising the following steps:

[0044] S1, monitor whether there is a train about to pass on the track through infrared sensors or by sharing the train's location information with the Internet, and transmit the detection results to the barrier controller;

[0045] S2. When the detection result shows that a train is about to pass, a command to close the crossing is sent through the controller module; at the same time, the detection unit detects whether there are stagnant vehicles or pedestrians in the crossing, and transmits the detection result to the barrier controller;

[0046] When the above detection result shows that there is no stationary vehicle or pedestrian, the motor brake is unlocked and the motor is driven to rotate, the barrier is lowered until it is fully in place and the light strip is lit;

[0047] When the above detection result is that there is a stagnant vehicle or pedestrian, the control module calculates the lowest height allowed for the vehicle or pedestrian to pass through the track, and obtains the initial rotation angle of the wood barrier at this height; the Hall sensor monitors the angle in real time, and sends a signal to control the motor to stop working when the angle is initially in place, and controls the wood barrier to rotate again after the vehicle or pedestrian passes until it is completely in place and the light strip is lit;

[0048] During the rotation of the above-mentioned wood barrier, the detection unit monitors in real time whether there are vehicles or pedestrians who have strayed into the track, and transmits the detection result to the wood barrier controller;

[0049] When the above detection result shows that there is no vehicle or pedestrian entering by mistake, the barrier machine works normally;

[0050] When the above detection result is that there is a vehicle or pedestrian who has strayed into the track, the control module calculates the minimum height at which the vehicle or pedestrian in the track is allowed to pass; if it needs to rise compared to the height of the barrier at this time, the controller controls the motor to reverse and control the barrier to rise to this angle; if it needs to fall compared to the height of the barrier at this time, the Hall sensor monitors the angle in real time. When it drops to this angle, the motor stops working and allows the vehicle or pedestrian who has strayed into the track to pass.

[0051] S3. After the wood barrier machine rotates to the right position, the wood barrier machine closing information is sent to the on-duty personnel or the centralized control system.

[0052] The above is only a specific implementation of the present invention, but the protection scope of the embodiments of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the embodiments of the present invention, which should be included in the protection scope of the embodiments of the present invention.
