Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a control method, a device and a medium for elevator operation, so as to solve the problem of poor comfort of the elevator under different operation conditions.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
As mentioned above, the elevator structure consists of counterweight, hoisting machine, wire rope and car, and the variation of the weight of the elevator on both counterweight side and car side during operation results in different magnitudes of traction or braking force required. Specifically, according to the weight difference between the counterweight side steel wire rope and the car side steel wire rope, the required traction force or braking force can be obtained, when the weight of people in the car is different and the height of the car is different, the weight difference between the counterweight side and the car side is different, and the load size is different naturally. When the current loop coefficient is larger, the response speed of the current loop to the signal is faster but the stability is poorer; when the current loop coefficient is smaller, the response speed is slow but the stability is good. Thus, a larger load generally requires a larger current loop factor and a smaller load requires a smaller current loop factor. The current loop coefficient sets up too big or undersize and all can lead to the comfort level of elevator to reduce, and the purpose of the scheme that this application embodiment provided is to select suitable current loop coefficient. Specifically, in order to adapt to the load change in the elevator operation process, the embodiment of the application provides a control method for elevator operation. Fig. 1 is a flowchart of a control method for elevator operation provided in an embodiment of the present application; as shown in fig. 1, the method comprises the steps of:
s10: the current running state of the elevator is obtained.
S11: the current loop coefficient for controlling the elevator is determined according to the current running state of the elevator.
S12: and controlling the elevator according to the determined current loop coefficient.
The running state of the elevator represents the load condition of the elevator, and the specific content is not limited. If the current running state of the elevator represents that the load of the elevator is larger, the current loop coefficient is larger; the current loop coefficient is smaller if the current operating state of the elevator characterizes the smaller the load of the elevator. In practice, the running state of the elevator may comprise the height of the car of the elevator, the driving state or braking state of the elevator, the ascending or descending of the elevator, etc.
Because the weight of the counterweight and the weight of the car itself are fixed, when the elevator is rated for about 45%, the car weight is equal to the weight of the counterweight, the car side will be heavier than the counterweight side when the elevator is fully loaded, and the counterweight side will be heavier than the car side when the elevator is empty. When the elevator car is in practical application, the small change of the passenger carrying weight in the elevator car can be ignored, only the weight of the elevator in a driving state or a braking state, the weight of the elevator in an ascending or descending state and the weight of the steel wire ropes at the counterweight side and the weight of the steel wire ropes at the elevator car side are considered, the weight difference between the counterweight side and the elevator car side can be estimated through the weight of the steel wire ropes at the two sides, and the weight of the steel wire ropes at the two sides can be determined according to the length of the steel wire ropes at the two sides. The weight difference between the counterweight side and the car side can be determined by the height of the car, and the car corresponds to different current loop coefficients when at different heights, in general the current loop coefficients are linearly related to the height of the car of the elevator, where positive and negative correlations are possible, in particular to the correlation determination of the weight difference between the counterweight side and the car side with the change in car height. For example, when the car is focused on the counterweight side, the higher the car floor, the more the wire rope is biased toward the counterweight side, the smaller the difference between the car side and the counterweight side, and the smaller the current loop coefficient; the lower the car floor, the more the wire rope is biased to the car side, the greater the difference between the car side and the counterweight side, and the greater the current loop coefficient. When the car side is lighter than the counterweight side, the lower the car floor is, the more the steel wire rope is deviated to the car side, the smaller the difference between the car side and the counterweight side is, and the smaller the current loop coefficient is; the higher the car floor, the more the wire rope is biased to the counterweight side, and the greater the difference between the car side and the counterweight side, the greater the current loop coefficient.
The braking state of the elevator indicates that the frequency converter does not need to exert force, the load drags the motor to rotate, and the frequency converter stabilizes the speed through braking; the driving state indicates that the frequency converter needs to exert force to drive the motor to drive the load to operate. When the car is focused on the counterweight side or the counterweight is focused on the car side, the states corresponding to the upward and downward directions of the elevator are different; for example, if the car is focused on the counterweight side, motor braking is required for the elevator down and motor driving is required for the motor up. If the counterweight is focused on the car side, the elevator down-going needs motor drive, and the motor up-going needs motor braking. Therefore, the heavier side of the car side and the counterweight side can be determined according to the specific driving state or braking state of the elevator and the ascending or descending state of the elevator, and the current loop coefficient is calculated by combining the height of the car. The particular state of the elevator being driven or braking here can be determined on the basis of the current direction of the drive circuit.
In the specific implementation, when the current loop coefficient is determined, a corresponding current loop formula can be selected according to the height of the elevator car, the driving state or braking state of the elevator and the ascending or descending of the elevator; and then determining the current loop coefficient through the selected current loop formula. It should be noted that, in the driving state, the formulas used for uplink and downlink are different; in the braking state, the formulas used for the uplink and the downlink are different. This is illustrated in a specific embodiment. The present embodiment is only used for calculating the proportional coefficient, and the integral coefficient can refer to the calculation mode. Setting a driving low-order operation parameter I1.90; driving a high-order operation parameter I1.92; braking low-order operation parameter I1.94; the brake high-order operation parameter is 1.96. The lower limit value of the height is I1.88, and the upper limit value of the height is I1.89. Wherein H is the car height.
When the elevator is ascending and in a driving state, if H is less than or equal to I1.88, the integral coefficient=driving low-order operation parameter I1.90. If I1.88< H < I1.89 and I1.90> I1.92, then the integral factor = I1.90- (I1.90-I1.92) × (H-I1.88)/(I1.89-I1.88). If I1.88< H < I1.89 and I1.90< I1.92, then the integral factor = i1.90+ (I1.92-I1.90) × (H-I1.88)/(I1.89-I1.88). If H is greater than or equal to I1.89, the integral coefficient = drive high order operational parameter I1.92.
When the elevator is ascending and in a braking state, if H is less than or equal to I1.88, the integral coefficient=driving low-order operation parameter I1.94. If I1.88< H < I1.89, I1.94> I1.96, then the integral factor = I1.94- (I1.94-I1.96) × (H-I1.88)/(I1.89-I1.88). If I1.88< H < I1.89, I1.94< I1.96, then the integral factor = i1.94+ (I1.96-I1.94) × (H-I1.88)/(I1.89-I1.88). If H is greater than or equal to I1.89, the integral coefficient = drive high order operational parameter I1.96.
When the elevator descends and is in a driving state, if H is less than or equal to I1.88, the integral coefficient=driving low-order operation parameter I1.92. If I1.88< H < I1.89, I1.90> I1.92, then the integral factor = I1.90- (I1.90-I1.92) × (I1.89-H)/(I1.89-I1.88). If I1.88< H < I1.89, I1.90< I1.92, then the integral factor = i1.90+ (I1.92-I1.90) × (I1.89-H)/(I1.89-I1.88). If H is greater than or equal to I1.89, the integral coefficient = drive high order operational parameter I1.90.
When the elevator descends and is in a braking state, if H is less than or equal to I1.88, the integral coefficient=driving low-order operation parameter I1.96. If I1.88< H < I1.89, I1.94> I1.96, then the integral factor = I1.94- (I1.94-I1.96) × (I1.89-H)/(I1.89-I1.88). If I1.88< H < I1.89, I1.94< I1.96, then the integral factor = i1.94+ (I1.96-I1.94) × (I1.89-H)/(I1.89-I1.88). If H is greater than or equal to I1.89, the integral coefficient = drive high order operational parameter I1.94.
Therefore, in the above mode, if the height of the elevator car is smaller than the height upper limit value and larger than the height lower limit value, the current loop coefficient is linearly related to the height of the elevator car, so that the comfort level of the elevator can be improved. If the height of the elevator car is greater than the upper limit value or less than the lower limit value, the current loop coefficient is a fixed value, so that unnecessary adjustment of the current loop coefficient is avoided.
According to the elevator operation control method, the current operation state of the elevator is obtained in the elevator operation process, and then the current loop coefficient for controlling the elevator is determined according to the current operation state of the elevator. The running state of the elevator represents the load condition of the elevator, so that the current loop coefficient can be set according to the current running state of the elevator, and if the current running state of the elevator represents the load of the elevator to be larger, the current loop coefficient is larger; if the current running state of the elevator represents that the load of the elevator is smaller, the current loop coefficient is smaller; and finally, controlling the elevator according to the determined current loop coefficient. In the main torque response of adjusting of electric current ring, in the elevator service scenario, need the electric current ring stronger when the load is great, electric current ring coefficient is bigger promptly, and the electric current ring that needs when the load is less is weaker promptly, and electric current ring coefficient is less, and this just can guarantee the stability of elevator operation, and use fixed electric current ring coefficient in the present scheme, can't satisfy the stability of elevator under different running state simultaneously, leads to the elevator comfort to be relatively poor. In the scheme, the current loop coefficient with proper size can be selected according to the current running state of the elevator, so that the elevator can stably run in various states, and the comfort level of the elevator is improved.
As mentioned in the above embodiments, the operating states of the elevator include: the height of the elevator car, the driving state or braking state of the elevator, and the ascending or descending of the elevator. In practical application, the weight of passengers in the car can be calculated, and the weight difference between the counterweight side and the car side is obtained by combining the weights of the steel ropes at two sides, but the weight sensor is added at the car, so that the change of the weight of passengers in the car can be ignored, and only the weight of the steel ropes at the counterweight side and the car side, which are in a driving state or a braking state and up or down of the elevator, are considered.
In practical application, determining the current loop coefficient for controlling the elevator according to the current running state of the elevator specifically comprises the following steps: selecting a corresponding current loop formula according to the height of the elevator car, the driving state or braking state of the elevator and the ascending or descending of the elevator; each current loop formula is calculated by adopting corresponding operation parameters; and then determining the current loop coefficient through the selected current loop formula. The current loop formula can be set according to practical application, so that the elevator can stably run. Specifically, determining the current loop coefficient for controlling the elevator according to the current running state of the elevator includes: if the height of the elevator car is smaller than the upper limit value and larger than the lower limit value, the current loop coefficient is linearly related to the height of the elevator car, so that the weight change of the steel wire rope is adapted. And determining the current loop coefficient for controlling the elevator based on the current operating state of the elevator comprises: if the height of the elevator car is greater than the upper limit value or less than the lower limit value, the current loop coefficient is a fixed value, so that frequent adjustment of the current loop coefficient can be avoided.
