[0002] With the development of science and technology, people's quality of life has been significantly improved. At the same time, more and more skyscrapers have given rise to a large demand for elevators. Elevators are indispensable vertical transportation tools in high-rise buildings. With the development of science and technology, people have also put forward higher and higher requirements on the performance of elevators; among them, being able to achieve senseless start when the elevator starts to improve the user's comfort is an important requirement. To achieve senseless start, the elevator is required to be in a state of force balance. In related technologies, the load data of the elevator is obtained by weighing, and then the corresponding traction force is applied to the elevator in combination with the elevator balance coefficient to achieve the elevator in a state of force balance. In addition, related technologies provide a variety of methods to improve the weighing accuracy of elevators to further reduce the weighing error to achieve senseless start of the elevator.

[0003] The inventors have found that there are at least the following problems in the related art: Under ideal circumstances, the above method can indeed use the load data obtained by weighing to achieve senseless starting of the elevator on any floor. However, due to practical limitations, there is a certain gap between the load data obtained by weighing and the actual load data of the elevator. The force on the elevator is greatly affected by the position of the elevator, which directly leads to the starting comfort being affected by the position. It is impossible to achieve senseless starting of all floors using only weighing data. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a method, device, electronic device and storage medium for starting an elevator, so as to reduce the influence of the elevator position change on the starting comfort, so that the elevator can achieve satisfactory starting comfort at different floors.

[0005] To solve the above technical problems, an embodiment of the present invention provides a method for starting an elevator, comprising: obtaining the position of the elevator before the elevator starts; obtaining the load data of the elevator obtained by weighing; obtaining the actual load data of the elevator based on the force and load data of the traction device of the elevator at the current position acting on the car; and applying the pre-torque required for starting the elevator based on the actual load data.

[0006] An embodiment of the present invention also provides a device for starting an elevator, comprising: a position acquisition module, a load acquisition module, and a starting module; the position acquisition module is used to obtain the position of the elevator before the elevator starts; the load acquisition module is used to obtain the load data of the elevator obtained by weighing; the starting module is used to obtain the actual load data of the elevator based on the force and load data of the traction device of the elevator at the current position acting on the car; and the pre-torque required for starting the elevator is applied according to the actual load data.

[0007] An embodiment of the present invention further provides an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the elevator start-up method as described above.

[0008] The embodiment of the present invention further provides a storage medium storing a computer program, and when the computer program is executed by a processor, the above-mentioned elevator starting method is implemented.

[0009] Compared with the related art, the embodiment of the present invention needs to first obtain the position of the elevator before the elevator starts, obtain the load data of the elevator obtained by weighing, and then obtain the actual load data of the elevator according to the force and load data of the traction device of the elevator at the current position acting on the car, and finally apply the pre-torque required for the elevator to start according to the actual load data. The embodiment of the present invention first obtains the position of the elevator before starting, so as to be able to obtain the force of the traction device acting on the car according to the position of the elevator. After obtaining the load data of the elevator, the load data is compensated by the force of the traction device at the position of the elevator acting on the car to obtain the actual load data of the elevator, and finally a force that can balance the elevator is applied to the elevator according to the actual load data of the elevator to start the elevator. It can avoid the obvious change in speed caused by the large error between the actual load of the elevator and the load obtained by weighing due to the different positions of the elevator when starting; improve the comfort of users when the elevator starts.

[0010] In addition, in one example, before obtaining the position of the elevator before the elevator starts, it also includes: controlling the elevator to run to different positions when the car is unloaded, and obtaining the force of the traction device acting on the car when the elevator is in different positions. By obtaining the force of the traction device acting on the car when the elevator is in different positions before the elevator starts, it is possible to obtain only the current position of the elevator when the elevator is in use, and the corresponding force of the traction device acting on the car can be obtained according to the current position, without having to obtain it every time the elevator starts, which is more convenient. Controlling the elevator to run to different positions when the car is unloaded can ignore the impact of the load in the car when analyzing the force on the elevator, and it is easier to obtain the force of the traction device acting on the car when the elevator is in different positions.

[0011] In addition, in one example, obtaining the force of the traction device acting on the car when the elevator is in different positions includes: controlling the elevator to run at a constant speed near the terminal station; wherein the constant speed is lower than a preset threshold, and the terminal station includes the upper terminal station and the lower terminal station of the elevator; obtaining the force of the traction device acting on the car when the elevator is in different positions according to the torque current when the elevator is running at a constant speed. When the elevator is running at a constant speed, it can be known that the elevator force system including the force provided by the motor torque current is balanced, and it is further obtained that the magnitude of the torque current and the magnitude of the force acting on the car by the traction device can be considered to have a linear relationship. It is simple, efficient and easy to obtain to obtain the force of the traction device acting on the car at different positions through the torque current.

[0012] In addition, in one example, according to the force of the traction device of the elevator acting on the car at the current position, and the load data, the ratio of the actual load data to the rated load of the elevator is obtained, including: according to the force and load data of the traction device acting on the car when the elevator is at different positions, the ratio of the actual load data to the rated load of the elevator is obtained by the following formula; the formula includes:

[0019] Itu represents the ratio of the torque current to the rated current of the motor when the elevator is moving upward at a constant speed at the upper terminal station;

[0020] Itd represents the ratio of the torque current to the rated current of the motor when the elevator is descending at a constant speed at the upper terminal station;

[0021] Ibu represents the ratio of the torque current to the rated current of the motor when the elevator is moving upward at a constant speed at the lower terminal station;

[0022] Ibd represents the ratio of the torque current to the rated current of the motor when the elevator is descending at a constant speed at the lower terminal station;

[0023] k represents the elevator balance coefficient measured when the elevator is in the middle position, 40%≤k≤50%;

[0024] H represents the total distance between the upper and lower stations;

[0025] h represents the actual position of the elevator before starting. The value of h is 0 when the elevator is at the lower station, and the value of h is H when the elevator is at the upper station.

[0026] h represents the ratio of the distance from the lower station to the total distance before the elevator starts; h is 0% when the elevator is at the lower station before starting, and 100% when the elevator is at the upper station before starting. It is more intuitive to obtain the ratio of the actual load data to the rated load of the elevator by the ratio of the load data to the rated load of the elevator, the ratio of the torque current to the rated current of the motor under different conditions, the elevator balance coefficient, and the ratio of the distance from the lower station to the total distance before the elevator starts, and it is more convenient and quick to calculate physical quantities of different dimensions in one formula through proportional calculation.

[0032] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0033] An embodiment of the present invention relates to a method for starting an elevator, which can be applied to an elevator control panel of an elevator control system. In this embodiment, the position of the elevator is obtained before the elevator is started, the load data of the elevator obtained by weighing is obtained, and the actual load data of the elevator is obtained according to the force and load data of the traction device of the elevator at the current position acting on the car; the pre-torque required for starting the elevator is applied according to the actual load data. The embodiment of the present invention first obtains the position of the elevator before starting, so as to be able to obtain the force of the traction device acting on the car according to the position of the elevator. After obtaining the load data of the elevator, the load data is compensated by the force of the traction device at the position of the elevator acting on the car to obtain the actual load data of the elevator, and finally a force that can balance the elevator is applied to the elevator according to the actual load data of the elevator to start the elevator. It can avoid the obvious speed change caused by the large error between the actual load of the elevator and the load obtained by weighing due to the different positions of the elevator when starting; improve the comfort of the user when the elevator starts. The implementation details of the method for starting the elevator of this embodiment are described in detail below. The following content is only the implementation details provided for the convenience of understanding, and is not necessary for implementing this solution.

[0034] The specific process of the elevator startup method in this embodiment is as follows Figure 1 As shown, in step 101, the elevator control panel obtains the position of the elevator before the elevator starts.

[0035] After obtaining the position of the elevator before the elevator starts in step 101, the load data of the elevator obtained by weighing is obtained in step 102.

[0036] In one example, there are many technologies in the related art that can improve the accuracy and stability of elevator weighing measurement. For example, the consistency of weighing data at different floors can be improved by eliminating the influence of micro-torsion deformation of the car frame caused by the weight change of the accompanying cable and compensation chain on the weighing measurement accuracy when the elevator is at different floors; the accuracy and stability of elevator weighing measurement can also be improved by correcting the weighing data deviation caused by aging of the weighing device and gap change; the accuracy and stability of elevator weighing measurement can also be improved by improving the data stability and accuracy of the weighing device itself. In this embodiment, because there are many related technologies for improving the accuracy and stability of elevator weighing measurement, one or several of them can be selected according to needs and used in combination, which is not limited in this embodiment.

[0037] After obtaining the load data obtained by weighing the elevator, step 103 is entered to obtain the actual load data of the elevator according to the force and load data of the traction device of the elevator at the current position acting on the car. The original weighing data is corrected according to the position of the elevator to offset the influence of the change in the length of the traction device such as cables, wire ropes, and compensation chains on the elevator force at different positions. In an example, before obtaining the position of the elevator before the elevator is started, step 101 also includes: controlling the elevator to run to different positions when the car is unloaded, and obtaining the force of the traction device acting on the car when the elevator is at different positions. Before the elevator is started, the force of the traction device acting on the car when the elevator is at different positions is obtained, so that only the current position of the elevator can be obtained when the elevator is in use, and the corresponding force of the traction device acting on the car can be obtained according to the current position, without having to obtain it every time the elevator is started, which is more convenient. Controlling the elevator to run to different positions when the car is unloaded can ignore the influence of the load in the car when analyzing the force of the elevator, and it is easier to obtain the force of the traction device acting on the car when the elevator is at different positions.

[0038] In one example, the force of the traction device acting on the car when the elevator is in different positions can be obtained by controlling the elevator to run at a constant speed near the terminal station; the constant speed is lower than a preset threshold, and the terminal station includes the upper terminal station and the lower terminal station of the elevator; the force of the traction device acting on the car when the elevator is in different positions is obtained according to the torque current when the elevator is running at a constant speed. When the elevator is running at a constant speed, it can be known that the elevator force system including the force provided by the motor torque current is balanced, and it is further obtained that the magnitude of the torque current and the magnitude of the force acting on the car by the traction device can be considered to have a linear relationship. Obtaining the force of the traction device acting on the car at different positions by the torque current is simple, efficient and easy to obtain. In the above example, controlling the elevator to run at a constant speed near the terminal station includes: controlling the elevator to start at a constant speed at the terminal station, and the start time is greater than a first preset time length; or controlling the elevator to crawl at the constant speed at the terminal station, and the crawling time is greater than a second preset time length. In this embodiment, the first preset time and the second preset time can be controlled between 1-3 seconds. In practical applications, the threshold of constant speed and the first preset time, the second preset time can be adjusted according to demand. There are many methods to obtain the force of the traction device acting on the car when the elevator is in different positions, such as the mass calculation method: according to the number and density (kg / m) of the accompanying cables, wire ropes, and compensation chains, that is, the traction device in this embodiment, as well as the traction ratio, the functional relationship between the elevator position and the load data correction can be calculated. Terminal station load balancing method: add appropriate loads to the car at the two end stations respectively to keep the car balanced, record the load in the car when the car just starts to go up and down, and use the average value of these two loads to calculate the balance coefficient at the two end stations. Then, according to the balance coefficient at the two end stations and the actual balance coefficient at the middle position of the elevator, the functional relationship between the elevator position and the load data correction can also be calculated. The above-mentioned mass calculation method requires more specifications and parameters, which are not easy for on-site debugging personnel to obtain; the terminal load balancing method requires preparing a large number of weights and moving the weights into the car, which is labor-intensive and time-consuming. Therefore, this embodiment adopts the above-mentioned method when the car is unloaded, controls the elevator to run at a constant low speed near the terminal station, and obtains the force of the traction device acting on the car when the elevator is in different positions based on the torque current of the constant low-speed section. It is more simple and efficient, and also helps to improve the efficiency of on-site weighing and debugging.

[0039] In one example, in order to better understand the above elevator starting method, a schematic diagram of an elevator structure is provided as follows: Figure 2 As shown, Figure 2From left to right, the position changes of the accompanying cable 201, the wire rope / steel belt 202, the compensation chain 203, the car 204, and the counterweight 206 relative to the traction wheel 205 are respectively shown when the elevator is in different parking positions. In this embodiment, the traction device mentioned is composed of the accompanying cable 201, the wire rope / steel belt 202, and the compensation chain 203. In other scenarios of actual operation, the traction device may also have different components. For example, some low-rise elevators do not have the compensation chain 203. The counterweight 206 is used to balance the weight of the elevator car 204, and the traction wheel 205 is used to transmit traction power to the elevator. It should be noted that the elevator structure schematic diagram provided in this embodiment is for the convenience of understanding and should not constitute any limitation on the elevator structure of the specific method for realizing the elevator starting of the present invention.

[0040] In one example, according to the force and load data of the traction device of the elevator at the current position acting on the car, obtaining the actual load data of the elevator includes: according to the force and load data of the traction device of the elevator at the current position acting on the car, obtaining the ratio of the actual load data to the rated load of the elevator; and then obtaining the actual load data of the elevator according to the ratio of the actual load data to the rated load of the elevator and the rated load of the elevator.

[0041] In one example, obtaining a ratio of actual load data to a rated load of an elevator includes: obtaining a ratio of actual load data to a rated load of the elevator according to force and load data of a traction device acting on a car when the elevator is at different positions by using the following formula; the formula includes:

[0055] h represents the ratio of the distance from the lower terminal station to the total distance before the elevator starts; h is 0% when the elevator is at the lower terminal station before starting, and h is 100% when the elevator is at the upper terminal station before starting. It is more intuitive to obtain the ratio of the actual load data to the rated load of the elevator through the ratio of the load data to the rated load of the elevator, the ratio of the torque current to the rated current of the motor under different conditions, the elevator balance coefficient, and the ratio of the distance from the lower terminal station to the total distance before the elevator starts, and it is more convenient and quick to calculate physical quantities of different dimensions in one formula through proportional calculation. After obtaining the ratio of the actual load data to the rated load of the elevator, since the rated load of the elevator is known, the actual load of the elevator can be easily obtained.

[0056] After the actual load of the elevator is obtained, the pre-torque required for starting the elevator can be applied according to the actual load data in step 104 to start the elevator, thereby realizing a senseless start of the elevator and improving the riding comfort of the user.

[0057] In this embodiment, the position of the elevator before starting is obtained first, so as to obtain the force of the traction device acting on the car according to the position of the elevator. After obtaining the load data of the elevator, the load data is compensated by the force of the traction device acting on the car at the position of the elevator to obtain the actual load data of the elevator. Finally, a force that can balance the elevator is applied to the elevator according to the actual load data of the elevator to start the elevator. This can avoid the obvious speed change caused by the large error between the actual load of the elevator and the load obtained by weighing due to the different positions of the elevator when starting; and improve the user's comfort when the elevator starts.

[0058] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps.
