Description

Technical Field

[0001] This application relates to the field of railway transportation technology, and in particular to a control method for turnout fixing locks. Background Technology

[0002] A turnout is a track connection device that allows locomotives and rolling stock to switch from one track to another. It is also one of the weakest links in the track and is typically installed in stations and marshalling yards. Before installation, turnouts need to be transported from the production site to the installation area. However, during transportation, to accommodate complex road conditions and turnouts of various sizes and specifications, locking devices are usually used to secure the turnouts to the transport vehicle, preventing instability and displacement during transport.

[0003] However, the aforementioned technologies have the following drawbacks: due to the potentially long transportation time, uneven road surfaces, and the fact that the turnouts themselves are usually irregularly shaped, the locking devices that secure the turnouts to the transport vehicle are prone to instability during transportation. This could cause the pressure applied by the locking devices to change during the transport vehicle's movement, resulting in the turnout shifting. This could easily cause the turnout's center of gravity to shift, leading to phenomena such as the turnout tipping over or falling off. This not only reduces transportation efficiency but, in severe cases, could even endanger the lives of the workers.

[0004] Therefore, providing a control method for turnout fixed locks that can ensure the locks remain stable at the required pressure value is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0057] Obtain the lock type and quantity corresponding to the turnout type;

[0058] Based on the lock model and the number of locks, and in conjunction with the quantity pressure rule, the corresponding first pressure threshold and second pressure threshold are obtained.

[0078] Optionally, controlling the locking device to perform a tightening operation based on the tightening signal includes:

[0079] A third pressure threshold is obtained based on the tightening signal;

[0080] When the current pressure value is less than or equal to the third pressure threshold, the fixed lock is controlled to perform a first tightening operation;

[0081] When the current pressure value is greater than the third pressure threshold and less than the first pressure threshold, the fixed lock is controlled to perform a second tightening operation;

[0082] Wherein, the third pressure threshold is greater than the first pressure threshold and less than the second pressure threshold, and the tightening speed of the first tightening operation is greater than the tightening speed of the second tightening operation.

[0086] When the current pressure value is less than the fourth pressure threshold and greater than the second pressure threshold, the fixed lock is controlled to perform a second release operation;

[0087] Wherein, the fourth pressure threshold is greater than the second pressure threshold, and the release speed of the first release operation is greater than the release speed of the second release operation.

[0088] In summary, the turnout fixing lock control method provided in this application sets a pressure tolerance range by establishing a first pressure threshold and a second pressure threshold. If the current pressure value exceeds the second pressure threshold, the lock is considered to be under excessive pressure, and a release signal is sent to the lock. Driven by a motor, the upper crossbar and lower hook lock are slowly released so that the current pressure value falls within the range defined by the first and second pressure thresholds. Conversely, if the current pressure value is less than the first pressure threshold during operation, the lock is considered to be under insufficient pressure. Similarly, upon receiving a tightening signal, the lock is driven by a motor to tighten the upper crossbar and lower hook lock, so that the current pressure value falls within the range defined by the first and second pressure thresholds. Therefore, based on the real-time current pressure value, the lock is controlled to perform different operations, achieving flexible control of the turnout fixing lock. Attached Figure Description

[0105] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0106] The specific structure of the turnout fixing lock based on which the turnout fixing lock control method provided in this application is provided is as follows:

[0107] The turnout fixing lock includes the lock body, air fixing bolt, upper crossbar, and lower hook lock. The upper crossbar and lower hook lock can be loosened and tightened by adjusting the position of the fixing bolt through the motor driving the thread in the crossbar.

[0108] During installation, the lower hook lock is connected to the fixed frame on the transport vehicle to generate force, the upper crossbar is fixed orthogonally to the turnout, and the locking force is set and fixed by a hand-held locking gun. Tightening the fixing bolts ensures that the locking force is within the safe locking range, thus completing the fixing of a fixed lock.

[0109] Of course, different types of locks can be used to control the turnout. For example, one type of lock has its bottom pinned to the fixed plate of the support platform, and the top pressure block presses against the turnout rail. By tightening the locking screw, horizontal locking is achieved. Another type of lock has its bottom hooked onto the channel steel of the support platform, and a pressure rod at the top presses against the turnout sleeper. By tightening the locking nut, vertical locking is achieved. When the turnout is placed on the transport vehicle mounting frame, the fixing lock provided in this application is used. The lower hook lock hooks onto the mounting frame, and the upper crossbeam passes through the turnout gap, orthogonally and horizontally fixing the turnout. Adjusting bolts are used for initial fixing.

[0110] This application provides a method for controlling turnout fixing locks, such as... Figure 1 As shown, it includes the following steps:

[0111] S101. Obtain the pressure value measured by the pressure sensor installed on the fixed lock as the current pressure value;

[0112] S102. Compare the current pressure value with the first pressure threshold and the second pressure threshold;

[0113] S103. If the current pressure value is less than the first pressure threshold, a tightening signal is generated;

[0114] S104. Control the fixed lock to perform a tightening operation according to the tightening signal and return to the initial step;

[0115] S105. If the current pressure value is greater than the second pressure threshold, a release signal is generated;

[0116] S106. Control the fixed lock to perform a release operation according to the release signal and return to the initial step;

[0117] S107. If the current pressure value is not less than the first pressure threshold or not greater than the second pressure threshold, a hold signal is generated;

[0118] S108. Control the fixed lock to perform a holding operation according to the holding signal and return to the initial step;

[0119] The first pressure threshold is less than the second pressure threshold.

[0120] The current pressure value in step S101 is measured by a pressure sensor installed on the fixed lock. After being obtained, it is sent to the cloud via a signal transmission module. Upon receiving the current pressure value, the cloud executes step S102, which compares the current pressure value with a first pressure threshold and a second pressure threshold. Based on the comparison result, it selects to proceed to step S103 or step S105. The first and second pressure thresholds are both preset pressure thresholds, and the first pressure threshold is less than the second pressure threshold.

[0121] If the current pressure value is less than the first pressure threshold, it means that the pressure value generated by the current fixing device is insufficient to securely fix the corresponding turnout. The pressure value needs to be increased. Therefore, the generation of a tightening signal in step S103 is executed, and the motor in the crossbar is controlled to execute step S104. That is, according to the tightening signal, the fixing device is controlled to perform a tightening operation to drive the thread to tighten the fixing bolt. Steps S101 and S012 are executed again to obtain the current pressure value in real time and compare it with the first pressure threshold and the second pressure threshold until the fixing device is controlled to complete the tightening operation on the corresponding turnout.

[0122] If the current pressure value is greater than the second pressure threshold, it means that the pressure value generated by the current fixed lock is too high, exceeding the pressure value that the corresponding stable turnout can withstand. The pressure value needs to be reduced. Therefore, the generation of the release signal in step S105 is executed, and the motor in the crossbar is controlled to execute step S106, that is, according to the release signal, the fixed lock is controlled to perform a release operation to drive the thread to loosen the fixing bolt, and steps S101 and S012 are re-executed in order to obtain the current pressure value in real time and compare it with the first pressure threshold and the second pressure threshold until the fixed lock is controlled to complete the release operation of the corresponding turnout.

[0123] If the current pressure value is not less than the first pressure threshold or not greater than the second pressure threshold, it indicates that the pressure value generated by the current fixing device is appropriate and can stably fix the corresponding turnout. There is no need to adjust the current pressure value. Therefore, the generation of the release signal in step S107 is executed, and the motor in the crossbar is controlled to execute step S106, that is, according to the holding signal, the fixing device is controlled to perform the holding operation to drive the threaded stabilizing fixing bolt, and steps S101 and S012 are re-executed so as to obtain the current pressure value in real time and compare it with the first pressure threshold and the second pressure threshold, and control the fixing device to complete the holding operation of the corresponding turnout.

[0124] It should be noted that in the above three scenarios, after re-executing steps S101 and S012 to obtain the current pressure value in real time and compare it with the first and second pressure thresholds, the specific subsequent steps will be selected based on the comparison results, namely step S103, step S105, or step S107. This allows the fixed locking device to perform the necessary operations on the turnout based on the real-time pressure value. Furthermore, each fixed locking device has its own unique ID. After various signals are generated, in addition to containing the type of operation to be performed, they also include the ID of the corresponding fixed locking device.

[0125] The fixed locking control method provided in this embodiment sets a pressure tolerance range by setting a first pressure threshold and a second pressure threshold. If the current pressure value exceeds the second pressure threshold, the locking device is considered to be under excessive pressure, and a release signal is sent to the locking device. Driven by a motor, the upper crossbar and lower hook lock are slowly released so that the current pressure value falls within the range defined by the first and second pressure thresholds. Conversely, if the current pressure value is less than the first pressure threshold during transport, the locking device is considered to be under insufficient pressure. Similarly, the locking device receives a tightening signal, and driven by a motor, the upper crossbar and lower hook lock are tightened so that the current pressure value falls within the range defined by the first and second pressure thresholds. Thus, based on the real-time current pressure value, the locking device is controlled to perform different operations, achieving flexible control of the turnout fixed locking device.

[0126] In one embodiment of this example, such as Figure 2 As shown, step S103, which involves generating a tightening signal if the current pressure value is less than the first pressure threshold, includes:

[0127] S201. Obtain the difference between the first pressure threshold and the current pressure value as the tightening pressure difference;

[0128] S202. According to the preset pressure control rules, obtain the tightening distance corresponding to the tightening pressure difference;

[0129] S203. Obtain the tightening time based on the tightening distance and the preset tightening speed;

[0130] S204. Bind the tightening time and tightening distance to generate a tightening signal.

[0131] In step S202, the preset pressure control rule is a pre-set correspondence between the pressure difference and the tightening distance or the loosening distance. This allows the corresponding tightening distance to be obtained based on the difference between the first pressure threshold obtained in step S201 and the current pressure value, i.e., the tightening pressure difference. Then, in step S203, combined with the pre-set preset tightening speed, the tightening time required to make the current pressure value reach the first pressure threshold is calculated. Thus, step S204 is executed to bind it together with the tightening distance to form the required tightening signal.

[0132] For example, if the first pressure threshold is 50N and the current pressure value is 30N, then the tightening pressure difference is 20N. The preset pressure control rule is that the bolt needs to move 1CM for every 10N, so the tightening distance is 2CM. According to the preset tightening speed, it takes 1 second for the bolt to move 1CM, so the tightening time is calculated to be 2 seconds. Then, the 2 seconds and 2CM are bound together to form the tightening signal corresponding to this fixed lock.

[0133] The fixed lock control method provided in this embodiment obtains the tightening distance corresponding to the tightening pressure difference according to the preset pressure control rules, combines the tightening distance with the preset tightening speed, and binds the obtained tightening time with the tightening distance to generate a corresponding tightening signal, so that the drive motor can effectively perform the required tightening operation according to the tightening signal.

[0134] In one embodiment of this example, such as Figure 3 As shown, step S105, which generates a release signal if the current pressure value is greater than the second pressure threshold, includes:

[0135] S205. Obtain the difference between the current pressure value and the second pressure threshold, and use it as the release pressure difference;

[0136] S206. According to the preset pressure control rules, obtain the release distance corresponding to the release pressure difference;

[0137] S207. Obtain the release time based on the release distance and the preset release speed;

[0138] S208. Generate a release signal by binding release time and release distance.

[0139] In step S206, the preset pressure control rule is a pre-set correspondence between the pressure difference and the release distance. This allows the corresponding release distance to be obtained based on the difference between the second pressure threshold obtained in step S205 and the current pressure value, i.e., the release pressure difference. Then, in step S207, combined with the pre-set preset release speed, the release time required to make the current pressure value reach the second pressure threshold is calculated. Thus, step S208 is executed to bind it together with the release distance to form the required release signal.

[0140] For example, if the second pressure threshold is 90N and the current pressure value is 110N, then the release pressure difference is 20N. The preset pressure control rule is that the bolt needs to move 1CM for every 10N, so the release distance is 2CM. According to the preset release speed, it takes 1 second for the bolt to move 1CM, so the release time is calculated to be 2 seconds. Then, the 2 seconds and 2CM are bound together to form the release signal corresponding to this fixed lock.

[0141] The fixed lock control method provided in this embodiment obtains the release distance corresponding to the release pressure difference according to the preset pressure control rules, combines the release distance with the preset release speed, and binds the obtained release time with the release distance to generate a corresponding release signal, so that the drive motor can effectively perform the required release operation according to the release signal.

[0142] In one embodiment of this example, such as Figure 4 As shown, step S102, before comparing the current pressure value with the first pressure threshold and the second pressure threshold, further includes:

[0143] S301. Obtain the model number of the fixed lock;

[0144] S302. Determine if the lock model has a corresponding pressure control rule;

[0145] S303. If there is a corresponding pressure control rule, then obtain the pressure control rule as the preset pressure control rule;

[0146] S304. If there is no corresponding pressure control rule, then obtain the default pressure control rule as the preset pressure control rule.

[0147] The lock model in step S301 refers to the specific type and corresponding model of the fixed lock. Because in actual use, different fixed locks can be selected depending on the type, size, and quantity of the turnout, commonly used lock models have pre-set pressure control rules. In step S302, it is determined whether the current lock model has pre-set pressure control rules, and based on the determination result, either step S303 or step S304 is executed.

[0148] If the judgment result indicates that there is a corresponding pressure control rule, it means that the current lock model has a preset pressure control rule. Then, step S303 is executed to obtain the pressure control rule as the preset pressure control rule. If the judgment result indicates that there is no corresponding pressure control rule, it means that the current lock model does not have a preset pressure control rule. Then, step S304 is executed to obtain the default pressure control rule as the preset pressure control rule. The default pressure control rule is a pre-set, unified pressure control rule for lock models that do not have a corresponding pressure control rule.

[0149] The fixed lock control method provided in this embodiment determines whether the lock model has a corresponding pressure control rule, and selects the corresponding pressure control rule or the default pressure control rule as the preset pressure control rule based on the determination result. This allows fixed locks of different models to obtain their corresponding preset pressure control rules, thereby improving the adaptability of the control method to different lock models.

[0150] In one embodiment of this example, such as Figure 5 As shown, after step S301, which involves obtaining the lock model of the fixed lock, the process further includes:

[0151] S305. Determine if the lock model is in the preset model list;

[0152] S306. If it is in the preset model list, then obtain the corresponding first pressure threshold and second pressure threshold according to the lock model;

[0153] S307. If not in the preset model list, obtain the first preset threshold as the first pressure threshold and obtain the second preset threshold as the second pressure threshold.

[0154] In practical use, depending on the lock model and the type, size, and quantity of the turnout, different first and second pressure thresholds for fixed locks can be selected or configured. Therefore, commonly used lock models are pre-set with corresponding first and second pressure thresholds. In step S305, it is determined whether the current lock model is in the preset model list, and based on the determination result, step S306 or step S307 is selected for execution.

[0155] If the determination result is in the preset model list, it means that the preset model list contains the first pressure threshold and the second pressure threshold corresponding to the current lock model. Then, step S306 is executed to obtain the first pressure threshold and the second pressure threshold. If the determination result is not in the preset model list, it means that the preset model list does not contain the first pressure threshold and the second pressure threshold corresponding to the current lock model. Then, step S307 is executed to obtain the first preset threshold as the first pressure threshold and obtain the second preset threshold as the second pressure threshold. The first preset threshold and the second preset threshold are preset and are uniform first and second thresholds for fixed locks that do not have corresponding pressure control rules.

[0156] The fixed lock control method provided in this embodiment determines whether the lock model is in a preset model list, and selects the corresponding first pressure threshold and second pressure threshold based on the determination result, or selects the first preset threshold and the second preset threshold as the first pressure threshold and the second pressure threshold, so that fixed locks of different models can obtain their corresponding first pressure threshold and second pressure threshold, thereby improving the adaptability of the control method to different lock models.

[0157] In practical use, the specific tightening and loosening operations vary depending on the locking mechanism corresponding to different lock models. In this embodiment, the following two implementation methods are selected as specific operation methods, as follows:

[0158] In one embodiment of this example, such as Figure 6 As shown, step S104, which involves controlling the fixed lock to perform a tightening operation based on the tightening signal and returning to the initial step, includes:

[0159] S401. Send a tightening signal to the control motor corresponding to the fixed lock;

[0160] S402. Control the motor to drive the lower hook lock and the upper crossbar of the fixed lock to move closer to each other until the current pressure value equals the first pressure threshold, so as to perform a tightening operation.

[0161] In one embodiment of this example, such as Figure 7 As shown, step S106, which involves controlling the fixed lock to perform a release operation based on the release signal and returning to the initial step, includes:

[0162] S403. Send a release signal to the control motor corresponding to the fixed lock;

[0163] S404. Control the motor to drive the lower hook lock and the upper crossbar of the fixed lock away from each other until the current pressure value equals the second pressure threshold, so as to perform the release operation.

[0164] To obtain the current pressure value of the locking device, it is necessary to combine the pressure values ​​of the upper crossbar and the lower hook lock. Therefore, it is necessary to obtain the pressure values ​​of both separately. In one embodiment of this invention, such as... Figure 8 As shown, step S101, which involves obtaining the pressure value measured by the pressure sensor installed on the fixed lock as the current pressure value, includes:

[0165] S501. Obtain the pressure value measured by the pressure sensor on the upper horizontal bar as the pressure value of the upper horizontal bar;

[0166] S502. Obtain the pressure value measured by the pressure sensor on the lower hook lock as the lower hook lock pressure value;

[0167] S503. Obtain the current pressure value based on the pressure value of the upper horizontal bar and the pressure value of the lower hook lock.

[0168] In one embodiment of this example, such as Figure 9 As shown, before step S101, which involves obtaining the pressure value measured by the pressure sensor installed on the fixed lock as the current pressure value, the following steps are included:

[0169] S601. Obtain the status signal of the fixed lock;

[0170] S602. Determine if the status signal is normal;

[0171] S603. If the status signal is abnormal, obtain the initialization configuration of the fixed lock;

[0172] S604. Based on the initialization configuration, initialize the fixed lock and return the status signal of the fixed lock;

[0173] S605. If the status signal is normal, proceed to the next step.

[0174] In practical applications, since each fixed lock needs to move synchronously with the turnout and the vehicle transporting the turnout, the lock itself may become uncontrollable or fail in pressure control performance due to collisions or other reasons. Therefore, in step S601, the status signal of the fixed lock is obtained, and in step S602, it is determined whether the status signal is normal. Based on the determination result, step S603 or step S605 is selected to be executed.

[0175] If the status signal is abnormal, it indicates a problem with the corresponding fixed lock. In step S603, the initialization configuration of the fixed lock is obtained. Then, in step S604, the fixed lock is initialized according to the initialization configuration. Afterwards, the process returns to step S601 to re-obtain the status signal of the fixed lock and re-determine if the status signal is normal. In this embodiment, if the fixed lock remains abnormal within a predetermined number of attempts, it is replaced with a spare, normal lock. If the status signal is normal within the predetermined number of attempts or under the current determination, the process proceeds to step S101, where the pressure value measured by the pressure sensor installed on the fixed lock is obtained as the current pressure value.

[0176] The fixed lock control method provided in this embodiment obtains an initialization configuration for locks with abnormal status signals by judging the status signals of the fixed locks, so as to initialize them. This can reduce the probability of lock failure or turnout fixing errors caused by abnormal fixed locks.

[0177] In one embodiment of this example, such as Figure 10 As shown, before step S101, which involves obtaining the pressure value measured by the pressure sensor installed on the fixed lock as the current pressure value, the following steps are included:

[0178] S701. Obtain the types of turnouts required for fixed turnouts;

[0179] S702. Determine whether the turnout type is in the preset type list;

[0180] S703. If it is in the preset type list, then according to the type of turnout, obtain the corresponding first pressure threshold and second pressure threshold.

[0181] S704. If not in the preset category list, obtain the first default threshold as the first pressure threshold and obtain the second default threshold as the second pressure threshold.

[0182] In practical applications, due to differences in turnout types or sizes, the corresponding first and second pressure thresholds will also differ. Therefore, commonly used turnout types will have their corresponding first and second pressure thresholds preset. In step 702, it is determined whether the lock model obtained in step S701 is in the preset type list, and based on the determination result, step S703 or step S704 is selected for subsequent execution.

[0183] If the turnout is in the preset type list, then step S703 is executed to obtain the first pressure threshold and the second pressure threshold corresponding to the turnout type; if it is not in the preset type list, then a preset first default threshold is obtained as the first pressure threshold and a second default threshold is obtained as the second pressure threshold, wherein the first default threshold and the second default threshold are preset and are two default thresholds for turnout types that do not have a corresponding pressure threshold.

[0184] The fixed locking control method provided in this embodiment determines whether the type of turnout is in a preset type list, and selects the corresponding first pressure threshold and second pressure threshold based on the determination result, or selects the first default threshold and the second default threshold as the first pressure threshold and the second pressure threshold, so that turnouts of different types can obtain their corresponding first pressure threshold and second pressure threshold, thereby improving the adaptability of the control method to different turnout types.

[0185] In one embodiment of this example, such as Figure 11 As shown, step S703, i.e., if it is in the preset type list, then according to the turnout type, obtaining the corresponding first pressure threshold and second pressure threshold includes:

[0186] S705. Obtain the lock type and quantity corresponding to the turnout type;

[0187] S706. Based on the lock model and the number of locks, and in conjunction with the quantity pressure rule, obtain the corresponding first pressure threshold and second pressure threshold.

[0188] The quantity pressure rule in step S706 is the range of pressure values ​​that each lock model corresponding to the turnout type can provide. Combined with the number of locks, the corresponding first pressure threshold and second pressure threshold can be obtained.

[0189] For example, the pressure value ranges of lock model A and lock model B are AN and BN respectively, and their quantities are X and Y. The coefficients of the first pressure threshold are AS1 and BS1 respectively, and the coefficients of the second pressure threshold are AS2 and BS2 respectively. Then, the first pressure threshold of lock model A is AN*AS1*X, and its second pressure threshold is AN*AS2*X. The first pressure threshold of lock model B is BN*BS1*Y, and its second pressure threshold is BN*BS2*Y.

[0190] The fixed lock control method provided in this embodiment obtains the first pressure threshold and the second pressure threshold corresponding to each lock model based on the lock model and the number of locks, combined with the quantity pressure rule, thereby improving the adaptability of the control method to different turnout types or different lock models.

[0191] In one embodiment of this example, such as Figure 12 As shown, after step S703, i.e., if it is in the preset type list, then according to the type of turnout, the corresponding first pressure threshold and second pressure threshold are obtained, the following steps are also included:

[0192] S801. Obtain the first centroid position corresponding to the type of turnout;

[0193] S802. Obtain the first center of gravity pressure value corresponding to the first center of gravity position;

[0194] S803. Define the fixed lock corresponding to the first center of gravity position as the first fixed lock;

[0195] S804. Reset both the first pressure threshold and the second pressure threshold of the first fixed lock to the first center of gravity pressure value.

[0196] In practical applications, due to the different types or sizes of turnouts, the corresponding center of gravity positions will also be different, and the corresponding center pressure values ​​will also be different. Therefore, the first center of gravity pressure value corresponding to the first center of gravity position of the turnout type will be obtained, and the first center of gravity position will be directly fixed with the first fixed lock. At this time, the first pressure threshold and the second pressure threshold of the first fixed lock need to be reset to the first center of gravity pressure value so as to keep the current pressure value of the first fixed lock at the first center of gravity pressure value.

[0197] The fixed locking control method provided in this embodiment sets a first fixed locking device at the first center of gravity position and resets both the first pressure threshold and the second pressure threshold of the first fixed locking device to the first center of gravity pressure value, thereby maintaining the first center of gravity position of the corresponding turnout with the first center of gravity pressure value and improving the stability of the entire turnout fixation.

[0198] Similar to the utilization of the first center of gravity position, such as Figure 13 As shown, in one embodiment of this example, it further includes:

[0199] S805. Obtain the second and third centroid positions corresponding to the turnout type;

[0200] S806. Obtain the second center of gravity pressure value corresponding to the second center of gravity position;

[0201] S807. Obtain the third center of gravity pressure value corresponding to the third center of gravity position;

[0202] S808. Define the fixed lock corresponding to the second center of gravity position as the second fixed lock;

[0203] S809. Define the fixed lock corresponding to the third center of gravity position as the third fixed lock;

[0204] S810. Reset both the first pressure threshold and the second pressure threshold of the second fixed lock to the second center of gravity pressure value;

[0205] S811. Reset both the first and second pressure thresholds of the third fixed lock to the third center of gravity pressure value.

[0206] In this embodiment, the first center of gravity position is the center point of the turnout, since the turnout is generally a uniform structure. The second and third center of gravity positions are the center points of the left and right halves of the turnout, respectively.

[0207] The fixed locking control method provided in this embodiment sets a second fixed locking device and a third fixed locking device at the second center of gravity position and the third center of gravity position, respectively. The first pressure threshold and the second pressure threshold of the second fixed locking device and the third fixed locking device are both reset to the second center of gravity pressure value and the third center of gravity pressure value, respectively. This can maintain the second center of gravity position and the third center of gravity position of the corresponding turnout with the second center of gravity pressure value and the third center of gravity pressure value, respectively, thereby further improving the stability of the entire turnout fixation.

[0208] In one embodiment of this example, such as Figure 14 As shown, it also includes:

[0209] S901. Determine the signal type of the current signal of the fixed lock;

[0210] S902. Obtain the indicator light corresponding to the fixed lock;

[0211] S903. If the signal type is a release signal, the control indicator light will display green;

[0212] S904. If the signal type is a tightening signal, the control indicator light will display red;

[0213] S905. If the signal type is a hold signal, the control indicator light will display yellow.

[0214] The fixed lock control method provided in this embodiment allows staff to intuitively understand the current working status of each fixed lock. It controls the indicator lights to display corresponding colors according to different signal types, so that staff can easily understand the working status and then perform corresponding processing or operations based on the working status.

[0215] In one embodiment of this example, such as Figure 15 As shown, step S104, which involves controlling the locking device to perform a tightening operation based on the tightening signal, includes:

[0216] S1001. Obtain the third pressure threshold based on the tightening signal;

[0217] S1002. When the current pressure value is less than or equal to the third pressure threshold, control the fixed lock to perform the first tightening operation;

[0218] S1003. When the current pressure value is greater than the third pressure threshold and less than the first pressure threshold, control the fixed lock to perform the second tightening operation;

[0219] Among them, the third pressure threshold is greater than the first pressure threshold and less than the second pressure threshold, and the tightening speed of the first tightening operation is greater than the tightening speed of the second tightening operation.

[0220] The fixed lock control method provided in this embodiment sets up a first tightening operation and a second tightening operation with gradually decreasing tightening speed. Taking a third pressure threshold as the dividing point, the first tightening operation is executed when the current pressure value is less than or equal to the third pressure threshold, and the second tightening operation is executed when the current pressure value is greater than the third pressure threshold but less than the first pressure threshold. This can speed up the entire tightening operation and improve operational efficiency.

[0221] In one embodiment of this example, such as Figure 16 As shown, step S106, which controls the fixed lock to perform a releasing operation based on the releasing signal, includes:

[0222] S1004. Obtain the fourth pressure threshold based on the release signal;

[0223] S1005. When the current pressure value is greater than or equal to the fourth pressure threshold, control the fixed lock to perform the first release operation;

[0224] S1006. When the current pressure value is less than the fourth pressure threshold and greater than the second pressure threshold, control the fixed lock to perform the second release operation;

[0225] Among them, the fourth pressure threshold is greater than the second pressure threshold, and the release speed of the first release operation is greater than the release speed of the second release operation.

[0226] The fixed lock control method provided in this embodiment sets a first release operation and a second release operation with gradually decreasing release speed. Taking a fourth pressure threshold as the dividing point, the first release operation is executed when the current pressure value is greater than or equal to the fourth pressure threshold, and the second release operation is executed when the current pressure value is less than the fourth pressure threshold but greater than the second pressure threshold. This can speed up the entire release operation and improve operational efficiency.
