Description

Technical Field

[0001] This application relates to the field of elevator operation and control management technology, and in particular to a track contact control method and system for elevators without traveling cables. Background Technology

[0002] A cableless elevator is a new type of elevator that does not use a traveling cable during operation. In a cableless elevator, the elevator's power and control signals are usually transmitted wirelessly or through other non-contact transmission methods. Compared with traditional elevator operation methods, this can improve elevator operating efficiency and save resources.

[0003] Currently, in elevators without traveling cables, power to the elevator car is mainly supplied by external power through the contact between the sliding contact line and the slider when the elevator is stopped. At this time, the larger the contact area between the sliding contact line and the slider, the better the current flow. However, during elevator operation, the elevator running resistance is inversely proportional to the contact area. At this time, the smaller the contact area, the smaller the elevator running resistance. Since the elevator operating state is complex and variable, it is crucial to accurately adjust the contact control parameters between the sliding contact line and the slider according to the elevator operating state for precise elevator operation control.

[0004] In summary, existing methods for controlling elevators without traveling cables suffer from a low degree of matching between the control parameters of the sliding contact line and the elevator's operating status, resulting in an inability to accurately control elevator operation. Summary of the Invention

[0005] The purpose of this application is to provide a track contact control method and system for elevators without traveling cables, in order to solve the technical problem that the existing operation control management methods for elevators without traveling cables have a low degree of matching between the contact control parameters of the sliding contact line and the elevator operating status, resulting in the inability to accurately control the operation of the elevator.

[0006] In view of the above problems, this application provides a track contact control method and system for elevators without traveling cables.

[0007] Firstly, this application provides a track contact control method for an elevator without a traveling cable. The method is implemented through a track contact control system for the elevator, comprising: installing a safety conductor rail and a sliding contact block; the safety conductor rail being installed beside the track for power supply, and the sliding contact block being installed near the car guide shoes; reading the operating status of the target elevator, wherein the operating status includes the operating scenario, real-time operating position, and operating speed; and training an adaptive motion control model based on the basic operating mechanism of the safety conductor rail and the sliding contact block, wherein the adaptive motion control model embeds a speed-based and... The implicit relationship of contact area; the operating status is transmitted to the adaptive operation control model, and based on the real-time operating position, the first operation control data is determined, wherein the real-time operating position includes at least a leveling position and a non-leveling position; combining the operating scenario and the operating speed, the elevator operating speed is dynamically adjusted based on the adaptive operation control model to determine the second operation control data; the first operation control data and the second operation control data are transmitted to the contact adjustment device to perform operation control management on the target elevator, wherein the contact adjustment device controls the elevator operation by adjusting the contact area between the sliding contact block and the safety sliding contact line.

[0008] Secondly, this application also provides a track contact control system for an elevator without a traveling cable, used to execute a track contact control method for an elevator without a traveling cable as described in the first aspect, wherein the system includes: a component installation module for installing a safety conductor rail and a sliding contact block, the safety conductor rail being installed beside the track for power supply, and the sliding contact block being installed near the car guide shoes; an operation status reading module for reading the operation status of the target elevator, wherein the operation status includes the operation scenario, real-time operation position, and operation speed; and a motion control model training module for training an adaptive motion control model based on the basic operation mechanism of the safety conductor rail and the sliding contact block, wherein the adaptive motion control model embeds a mechanism based on speed and contact area. The implicit relationship; a first operation control data determination module, which transmits the operating status to the adaptive operation control model and determines the first operation control data based on the real-time operating position, wherein the real-time operating position includes at least a leveling position and a non-leveling position; a second operation control data determination module, which combines the operating scenario and the operating speed and makes dynamic adjustment decisions on the elevator operating speed based on the adaptive operation control model to determine the second operation control data; an elevator operation control management module, which transmits the first operation control data and the second operation control data to a contact adjustment device to perform operation control management on the target elevator, wherein the contact adjustment device controls the elevator operation by adjusting the contact area between the sliding contact block and the safety sliding contact line.

[0009] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0010] 1. By installing a safety conductor rail and a sliding contact block, wherein the safety conductor rail is installed beside the track for power supply, and the sliding contact block is installed near the car guide shoe; the operating status of the target elevator is read, wherein the operating status includes the operating scenario, real-time operating position, and operating speed; based on the basic operating mechanism of the safety conductor rail and the sliding contact block, an adaptive operation control model is trained, wherein the adaptive operation control model has an implicit relationship based on speed and contact area; the operating status is transmitted to the adaptive operation control model, and based on the real-time operating position, first operation control data is determined, wherein the real-time operating position includes at least a leveling position and a non-leveling position; combining the operating scenario and the operating speed, the elevator operating speed is dynamically adjusted based on the adaptive operation control model to determine second operation control data; the first operation control data and the second operation control data are transmitted to a contact adjustment device to perform operation control management of the target elevator, wherein the contact adjustment device controls the elevator operation by adjusting the contact area between the sliding contact block and the safety conductor rail. In other words, by constructing an adaptive operation and control model, the first operation and control data is determined based on the elevator's real-time operating position, and the second operation and control data is determined based on the elevator's operating scenario and operating speed. Then, based on the first and second operation and control data, the contact area between the sliding contact block and the safety sliding contact line can be intelligently adjusted. This achieves the technical goal of precisely controlling the operation of an elevator without a traveling cable, thereby improving the stability of elevator operation.

[0011] 2. By intelligently adjusting the contact area between the sliding contact block and the safety sliding contact line, the maximum contact can be ensured when the cable-free elevator reaches the level, so that the current can flow smoothly. When the elevator is running in a non-level position, the contact area is zero, which reduces the running resistance, ensures the stability of the elevator operation, and achieves the effect of energy saving and emission reduction.

It should also be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all of them.

[0021] Example 1

[0022] Please see the appendix Figure 1 This application provides a track contact control method for an elevator without a traveling cable, wherein the method is applied to a track contact control system for an elevator without a traveling cable, and the method specifically includes the following steps:

[0023] Step 1: Install safety conductor rail and sliding contact block. The safety conductor rail is installed beside the track for power supply, and the sliding contact block is installed near the car guide shoe.

[0024] Specifically, a cableless elevator refers to an elevator that does not use a traveling cable during operation. Compared with traditional elevators, it can reduce the cost of maintenance and cable replacement, while also reducing elevator weight and improving operating efficiency. The method provided in this application is used to intelligently control the contact between the sliding contact line and the slider of a cableless elevator based on the actual operating state of the elevator, thereby achieving precise control of elevator operation. The method is specifically implemented in a track contact control system for a cableless elevator.

[0025] First, a safety conductor rail and sliding contact blocks are installed on the cableless elevator. The safety conductor rail is installed beside the track for power supply, and the sliding contact blocks are installed near the car guide shoes. The car guide shoes are installed under the elevator car's upper beam and bottom safety clamp seat, and their main function is to move back and forth along fixed guide rails installed on the building shaft wall to prevent the elevator car from tilting or swaying during operation. When the elevator stops at the landing position, the sliding contact blocks contact the safety conductor rail under the electromagnetic force of the electromagnet, energizing the car and charging the batteries inside the car. When the elevator leaves the landing position, the electromagnet is de-energized, and the sliding contact blocks do not contact the safety conductor rail under the action of the spring. In addition, other batteries in the elevator provide power for lighting and communication during operation.

[0026] By installing safety conductor rails and contact blocks, support is provided for the contact control of the conductor rail and slider in elevators without traveling cables, thereby enabling the purpose of controlling elevator operation.

[0027] Step 2: Read the operating status of the target elevator, including the operating scene, real-time operating position, and operating speed;

[0028] Specifically, the operating status of the target elevator is read. This operating status can be acquired through data monitoring using installed sensors, including image sensors, positioning sensors, and speed sensors. The operating status includes the operating scene, real-time operating position, and operating speed. The operating scene includes information such as elevator load and usage location. Obtaining the operating status of the target elevator provides support for the next step of analyzing the operating status to obtain suitable contact control parameters for the conductor rail and slider, thereby improving the accuracy and rationality of the conductor rail and slider contact control parameter settings.

[0029] Step 3: Based on the basic operating mechanism of the safety conductor rail and the conductor block, train an adaptive operation and control model. The adaptive operation and control model has an implicit relationship based on speed and contact area.

[0030] Specifically, a basic operating mechanism is set up based on the safety sliding contact line and the sliding contact block. The basic operating mechanism is as follows: when the elevator stops at the level position, the sliding contact block is in contact with the safety sliding contact line under the electromagnetic force of the electromagnet, the car is energized, and the battery in the car is charged; when the elevator leaves the level position, the electromagnet is de-energized, and at this time, under the action of the spring, the sliding contact block does not contact the safety sliding contact line.

[0031] First, an adaptive operation and control model is constructed, which embeds an implicit relationship based on speed and contact area. The contact area refers to the contact area between the safety conductor rail and the sliding contact block. The implicit relationship is a mapping between elevator speed and contact area, where the faster the elevator speed, the smaller the required contact area and the lower the elevator's running resistance. Then, based on the basic operating mechanism, the adaptive operation and control model is trained to obtain an adaptive operation and control model containing a standard mapping relationship between elevator speed and contact area, where there is a one-to-one correspondence between elevator speed and contact area.

[0032] Alternatively, a hidden relation layer of the adaptive operation and control model can be constructed based on a BP neural network, where the input data of the hidden relation layer is the elevator speed and the output data is the contact area. Then, multiple sample training data are collected, including sample elevator speed and sample contact area. The hidden relation layer is then trained under supervision using the multiple sample training data to obtain a hidden relation layer that tends to converge, and the hidden relation layer is then embedded into the adaptive operation and control model.

[0033] By constructing an adaptive operation and control model, support is provided for the next step of intelligent analysis of the contact control parameters between the sliding contact line and the slider based on the elevator's operating status. At the same time, it can improve the accuracy and efficiency of obtaining the contact control parameters between the sliding contact line and the slider.

[0034] Step 4: Transmit the operating status to the adaptive operation control model, and determine the first operation control data based on the real-time operating position, wherein the real-time operating position includes at least the level position and the non-level position;

[0035] Specifically, the operating status is transmitted to the adaptive operation control model, which identifies the real-time operating position within the operating status. The real-time operating position includes at least a level position and a non-level position. Based on the identification result, first operation control data is determined. This first operation control data indicates that when the real-time operating position is level, the sliding contact block is in contact with the safety conductor rail; or when the real-time operating position is non-level, the sliding contact block is neither in contact with nor not in contact with the safety conductor rail. Determining this first operation control data provides a basis for the next step of adjusting the contact between the sliding contact block and the safety conductor rail.

[0036] Step 5: Combining the operating scenario and the operating speed, make dynamic adjustment decisions on the elevator operating speed based on the adaptive operation control model to determine the second operation control data;

[0037] Specifically, the operating scenario and the operating speed are input into the adaptive operation control model. Dynamic adjustment decisions are made based on the elevator's operating speed. These dynamic decisions involve intelligently analyzing the implicit relationship layer of the adaptive operation control model by inputting the elevator's operating speed, outputting the contact area corresponding to the real-time operating speed, and using this contact area as second operation control data. This second operation control data provides a basis for the next step of adjusting the contact between the sliding contact block and the safety sliding contact line.

[0038] Step Six: Transmit the first operation control data and the second operation control data to the contact adjustment device to perform operation control management on the target elevator. The contact adjustment device controls the elevator operation by adjusting the contact area between the sliding contact block and the safety sliding contact line.

[0039] Specifically, the first and second operation control data are transmitted wirelessly to a contact adjustment device. The contact adjustment device includes components such as the sliding contact block and the safety sliding contact line. The elevator operation is controlled by adjusting the contact area between the sliding contact block and the safety sliding contact line. Then, the contact mode between the sliding contact block and the safety sliding contact line in the contact adjustment device is determined based on the first operation control data. The contact mode includes contact and non-contact. When the contact mode is contact, the contact area between the sliding contact block and the safety sliding contact line in the contact adjustment device is determined based on the second operation control data, thereby realizing the operation control management of the target elevator.

[0040] The described track contact control method for elevators without traveling cables is applied to a track contact control system for elevators without traveling cables. It can solve the technical problem that existing operation and control management methods for elevators without traveling cables have a low degree of matching between the contact control parameters of the sliding contact line and the sliding block and the elevator's operating status, resulting in the inability to accurately control the elevator's operation. First, a safety conductor rail and a sliding contact block are installed. The safety conductor rail is installed beside the track for power supply, and the sliding contact block is installed near the car guide shoes. Then, the operating status of the target elevator is read, including the operating scenario, real-time operating position, and operating speed. Next, based on the basic operating mechanism of the safety conductor rail and the sliding contact block, an adaptive motion control model is trained. This adaptive motion control model embeds an implicit relationship based on speed and contact area. Next, the operating status is transmitted to the adaptive motion control model. Based on the real-time operating position, first motion control data is determined, including at least a leveling position and a non-leveling position. Furthermore, combining the operating scenario and the operating speed, a dynamic adjustment decision for the elevator's operating speed is made based on the adaptive motion control model to determine second motion control data. Finally, the first and second motion control data are transmitted to a contact adjustment device for motion control management of the target elevator. The contact adjustment device controls the elevator operation by adjusting the contact area between the sliding contact block and the safety conductor rail. By constructing an adaptive operation and control model, the first operation and control data is determined based on the elevator's real-time operating position, and the second operation and control data is determined based on the elevator's operating scenario and speed. Then, based on the first and second operation and control data, the contact area between the sliding contact block and the safety sliding contact line is intelligently adjusted, which can achieve the technical goal of precise control of elevator operation and improve the technical effect of elevator operation stability.

[0041] Furthermore, step four of this application includes:

[0042] The read operating status of the target elevator is temporarily stored in the running file, and a communication connection is established between the running file, the adaptive operation control model, and the contact adjustment device.

[0043] The adaptive operation control model includes a parallel standard operation control branch and an adaptive control branch, wherein the standard operation control branch is in a continuous start state along with the elevator operation.

[0044] Specifically, after reading the operating status of the target elevator, the reading is first temporarily stored in an operating file. Then, a communication connection is established between the operating file, the adaptive motion control model, and the contact adjustment device using wireless communication. Wireless communication refers to a communication method that does not require a cable connection and utilizes the propagation characteristics of electromagnetic waves in space for information exchange, offering advantages such as high flexibility and portability. The operating status is then transmitted to the adaptive motion control model.

[0045] The adaptive motion control model includes a parallel standard motion control branch and an adaptive control branch. When the elevator is running, the standard motion control branch is in the start state.

[0046] Furthermore, step four of this application also includes:

[0047] Identify the real-time operating position; if the real-time operating position is at a level position, determine the first contact parameter, which is determined based on the maximum contact area.

[0048] If the real-time running position is in a non-flat position, a second contact parameter is determined based on the uniform running speed, and the second contact parameter is determined based on the minimum contact area.

[0049] Specifically, if the target elevator is in a constant speed control mode, the method for determining the first motion control data based on the real-time operating position is as follows: First, the real-time operating position is identified. When the real-time operating position is at a level position, a first contact parameter is determined. The first contact parameter is the maximum contact area between the sliding contact block and the safety sliding contact line, used to ensure smooth current flow. When the real-time operating position is not at a level position, a second contact parameter based on the constant speed is determined. The second contact parameter is the minimum contact area between the sliding contact block and the safety sliding contact line. The minimum contact area can be set based on the actual situation; ideally, the minimum contact area is zero. The first motion control data is either the first contact parameter or the second contact parameter.

[0050] Further details are attached. Figure 2 As shown, step five of this application includes:

[0051] Based on the operating scenario and the operating speed, dynamic adjustment decisions are made to determine adaptive control commands;

[0052] Upon receiving the adaptive control command, the adaptive regulation branch is activated, and an adaptive regulation decision is made based on the dynamic regulation requirements to determine the second operation control data. The second operation control data includes dynamic contact parameters, which are negatively correlated with the operating speed.

[0053] Specifically, when making dynamic control decisions on elevator operating speed based on the adaptive operation control model, firstly, the operating scenario and the operating speed are input into the adaptive operation control model for dynamic control decision-making to determine adaptive control commands. When the adaptive operation control model receives the adaptive control commands, it activates the adaptive control branch in the adaptive operation control model, determines the dynamic control requirements based on the operating scenario, and further makes adaptive control decisions based on the dynamic control requirements to determine second operation control data. The second operation control data includes dynamic contact parameters, which are negatively correlated with the operating speed. The dynamic contact parameters are the dynamic contact area between the sliding contact block and the safety sliding contact line. The larger the operating speed, the smaller the dynamic contact parameters; the smaller the operating speed, the larger the dynamic contact parameters. For example, when the operating scenario is an abnormal scenario or a scenario with control requirements, such as excessive elevator load or unstable elevator operation, adaptive dynamic control of the elevator operating speed is performed based on the actual state, i.e., real-time dynamic adjustment of the contact area.

[0054] By setting dynamic control requirements based on elevator operation scenarios and making adaptive control decisions based on these requirements, the matching degree between contact parameters and control requirements can be improved, thereby meeting the control requirements and improving the accuracy and rationality of elevator operation control.

[0055] Furthermore, step six of this application includes:

[0056] Read the basic configuration information of the target elevator and determine the safety threshold based on load and operating speed;

[0057] By narrowing the safety threshold within a predetermined range, operational constraints are determined.

[0058] The operating constraint relationships are traversed, and target constraint conditions based on the operating state are matched to control and compensate the contact adjustment device.

[0059] Specifically, after transmitting the first and second operation control data to the contact adjustment device, the basic configuration information of the target elevator is first read. The basic configuration information includes rated load capacity, running speed, operating mode, control mode, etc. Then, based on the basic configuration information, a safety threshold value based on load and running speed is determined. The safety threshold value refers to the maximum safe running speed corresponding to the load.

[0060] A predetermined interval is obtained, which is the adjustment range of the safety threshold value. This interval can be set according to actual operational needs and elevator control deviations. Higher operational safety requirements and greater elevator control deviations result in a larger predetermined interval. The purpose of setting this predetermined interval is to increase the fault tolerance rate, ensuring safe elevator operation even with some deviations in elevator control performance. Then, the predetermined interval is subtracted from the safety threshold value, and the difference is used as the operational constraint.

[0061] The operation constraint relationship is traversed and analyzed, that is, the contact area adjustment analysis is performed according to the operation constraint relationship, and the target constraint condition based on the operation state is matched. The target constraint condition refers to the minimum contact area limit between the sliding contact block and the safety sliding contact line. Then, the contact adjustment device is controlled and compensated according to the target constraint condition, that is, the contact area in the contact adjustment device is controlled to be greater than or equal to the target constraint condition.

[0062] By adjusting the safety threshold value through a predetermined range, an operational constraint relationship is obtained. Then, based on the matching of the operational constraint relationship, the target constraint condition is obtained to control and compensate the contact adjustment device, which can prevent the elevator running speed from exceeding the safety threshold value and improve the safety of elevator operation control.

[0063] Furthermore, step six of this application also includes:

[0064] Determine the operation and control management cycle and read the periodic operation and control management data of the target elevator;

[0065] Based on the operation and control management cycle, abnormal management data that meets the predetermined frequency are mined and control tracing is performed to determine abnormal tracing characteristics, which include hard control dimensions and soft control dimensions.

[0066] Based on the aforementioned anomaly tracing characteristics, management optimization is performed on the target elevator, wherein the optimization dimensions include hardware operation and maintenance management and incremental model learning.

[0067] Specifically, after implementing operation and control management on the target elevator, the operation and control management cycle is first determined. This cycle is a relatively long period of time, which can be set by those skilled in the art according to actual conditions, such as 15 days or 30 days. Then, the periodic operation and control management data of the target elevator is read, including operation data, fault data, maintenance data, passenger feedback data, etc.

[0068] Based on the aforementioned operation and control management cycle, abnormal management data exceeding a predetermined frequency in the periodic operation and control management data are mined. The predetermined frequency can be set by those skilled in the art according to actual conditions. Abnormal management data is obtained, and then the abnormal management data is traced for control. Control tracing refers to analyzing the abnormal management data, identifying the causes of the abnormal management data, and determining the abnormal tracing characteristics based on the analysis results. The abnormal tracing characteristics include hardware control dimensions and software control dimensions. The hardware control dimension refers to abnormalities in hardware equipment, such as aging elevator components or poor elevator assembly quality leading to abnormal elevator operation. The software control dimension refers to abnormal elevator operation caused by external factors or deviations in control parameters.

[0069] Then, based on the anomaly tracing characteristics, the management of the target elevator is optimized. The optimization dimensions include hardware operation and maintenance management and incremental model learning. Hardware operation and maintenance management refers to targeted optimization of the hardware control dimensions, such as maintenance and repair of elevator components and replacement of aging parts. Incremental model learning refers to optimizing the adaptive operation and control model based on the principle of incremental learning to improve the accuracy of the model's output. Incremental learning refers to continuously introducing new data to further improve and optimize the model's ability to build upon an existing model. This learning method allows the model to adapt to constantly changing environments and data distributions, thus maintaining its continuous effectiveness and accuracy. Incremental model learning typically involves adding new layers or parameters to the existing model to handle new data or tasks. This approach preserves the model's original knowledge while learning new knowledge, thus avoiding the computational and time costs of retraining the entire model.

[0070] Furthermore, step six of this application also includes:

[0071] Retrieve the operation status records of the target elevator for a predetermined time, and mine the status pattern characteristics, wherein the status pattern characteristics satisfy the generalization criterion;

[0072] Based on the aforementioned state pattern characteristics, combined with the power supply decision model, a power supply balance decision is made between the car energy storage and the backup power supply, and elevator energy supply data based on the pre-supply ratio is determined. The critical judgment criteria for different state pattern characteristics are different.

[0073] Based on the elevator power supply data, the target elevator is managed for charging and discharging power flow.

[0074] Specifically, the system retrieves the operational status records of the target elevator for a predetermined period. This predetermined period can be set according to actual conditions, such as 60 days or 120 days, and is significantly longer than the operational control management cycle. Then, based on these operational status records, the system mines status pattern characteristics. These pattern characteristics refer to elevator operational features exhibiting certain regularities. Furthermore, these pattern characteristics satisfy a generalization criterion, meaning that the pattern characteristics are not isolated cases but are comprehensive and representative of universal patterns.

[0075] Based on the aforementioned state-related characteristics and combined with a power supply decision model, a power supply balance decision is made between the car's energy storage and the backup power supply. This power supply decision model can be constructed based on a BP neural network and trained using historical data. For example, during peak elevator operation, when the car battery charge is below a critical value, the backup power supply is used, and the energy supply ratio is determined. This energy supply ratio refers to the ratio of the original power supply from the car battery to the backup power supply. Elevator energy supply data based on this pre-energy supply ratio is then determined. The critical value criteria differ depending on the specific state-related characteristics. For example, the higher the peak operating level of the elevator, the larger the corresponding critical value, and the greater the electrical energy required by the car, i.e., the larger the required proportion of backup power. Finally, based on the elevator energy supply data, the target elevator's charging and discharging energy flow is managed.

[0076] By mining the characteristics of state patterns and making power supply balancing decisions based on these characteristics, the reliability and safety of car battery power supply can be improved, thereby ensuring the stability and safety of elevator operation.

[0077] In summary, the track contact control method for elevators without traveling cables provided in this application has the following technical advantages:

[0078] 1. By constructing an adaptive operation control model and determining the first operation control data based on the elevator's real-time operating position, and determining the second operation control data based on the elevator's operating scenario and speed; then, by intelligently adjusting the contact area between the sliding contact block and the safety sliding contact line based on the first and second operation control data, the technical goal of precisely controlling elevator operation can be achieved, thereby improving the technical effect of elevator operation stability.

[0079] 2. By constructing an adaptive operation and control model, support is provided for intelligent analysis of the contact control parameters between the sliding contact line and the slider based on the elevator's operating status. This also improves the accuracy and efficiency of obtaining the contact control parameters. By setting dynamic control requirements in conjunction with the elevator's operating scenario and making adaptive control decisions based on these requirements, the matching degree between the contact parameters and the control requirements can be improved, thereby meeting the control requirements and enhancing the accuracy and rationality of elevator operation control.

[0080] 3. By adjusting the safety threshold value through a predetermined range, an operational constraint relationship is obtained; then, based on the matching of the operational constraint relationship, the target constraint conditions are obtained to control and compensate the contact adjustment device, which can prevent the elevator running speed from exceeding the safety threshold value and improve the safety of elevator operation control.

[0081] Example 2

[0082] Based on the same inventive concept as the track contact control method for a non-traveling cable elevator described in the foregoing embodiments, this application also provides a track contact control system for a non-traveling cable elevator. Please refer to the appendix. Figure 3 The system includes:

[0083] The component installation module 11 is used to install a safety sliding contact line and a sliding contact block. The safety sliding contact line is installed beside the track for power supply, and the sliding contact block is installed near the car guide shoe.

[0084] The operation status reading module 12 is used to read the operation status of the target elevator, wherein the operation status includes the operation scene, real-time operation position and operation speed;

[0085] The operation control model training module 13 is used to train an adaptive operation control model based on the basic operating mechanism of the safety sliding contact line and the sliding contact block. The adaptive operation control model has an implicit relationship based on speed and contact area.
