Detailed Description
The conception and the technical effects produced by the present invention will be clearly and completely described in conjunction with the embodiments below to fully understand the objects, features and effects of the present invention. It is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present invention based on the embodiments of the present invention.
When the elevator is in a normal running state, the elevator controller controls the elevator to run according to the received starting signal. The elevator operation control method of the invention is characterized in that the pre-operation process is added in the elevator operation process, the operation data of the elevator is collected in the pre-operation process, and the load condition of the elevator is detected and the operation of the elevator is controlled according to the operation data, and the elevator operation control method is specifically shown in figure 1.
Step S1, after receiving a starting signal, an elevator controller controls an elevator to run according to a first running curve, and obtains a first torque output by a traction motor of the elevator when the elevator runs according to the first running curve.
Specifically, the embodiment of the invention adds a pre-running process based on the existing elevator running time sequence. The pre-running process is that the elevator controller plans a section of running curve, namely a first running curve, according to actual parameters of the elevator or user settings, and when different floors are met, the first running curve of the embodiment of the invention can be different and can be determined according to actual conditions of different floors. The elevator is in a normal working state, and an elevator controller acquires a first running curve when the elevator is started, and outputs driving voltage to the traction motor according to the first running curve so as to control the elevator car to slightly move upwards or downwards; and when the driving voltage reaches a preset frequency, acquiring the output torque of the traction motor as a first torque. The first curve can be planned in advance according to the application occasion of the elevator and the like.
And S2, acquiring full-load torque corresponding to the current floor and running direction of the elevator.
The full-load torque can be obtained in a self-learning mode after the elevator is installed and before the normal load is used. Specifically, after the elevator is installed, the elevator is in an empty load state, and the elevator is triggered to enter a load detection self-learning stage by manually setting a function code. Of course, in practical applications, the full load torque may be obtained by any other existing method.
In the load detection self-learning phase, the elevator controller acquires torque data output by the traction machine when the traction machine ascends or descends on each floor, and stores all the torque data in the storage unit. After the load detection self-learning is finished, all the torque data of the elevator controller are processed to obtain a plurality of full-load torques of the elevator as reference data, and the full-load torques are used for judging whether the elevator is overweight or not in normal operation.
And step S3, confirming whether the elevator is overloaded or not by comparing the first torque and the full-load torque, and controlling the elevator to run in different modes according to the overload condition of the elevator.
After the load detection has ended from the learning phase, the elevator can be brought into a normal operating state (i.e. the elevator starts people/load). When the elevator is started each time, the elevator controller controls the elevator to operate according to a first operation curve and obtains a first torque, and then the first torque is compared with a full-load torque according to the current floor and the operation direction of the elevator, so as to judge whether the elevator is overweight.
Specifically, when the elevator is on any floor, if the first torque is larger than the uplink full-load torque of the corresponding floor, the overload of the elevator is confirmed, and if the first torque is smaller than or equal to the uplink full-load torque of the corresponding floor, the overload of the elevator is confirmed; when the elevator runs down on any floor, if the first torque is larger than the descending full-load torque of the corresponding floor, the overload of the elevator is confirmed, and if the first torque is smaller than or equal to the descending full-load torque of the corresponding floor, the non-overload of the elevator is confirmed. When the elevator is not overloaded, the elevator controller controls the elevator to run to a target floor; when the elevator is overloaded, the elevator controller controls the elevator car to run to the door zone of the current floor, opens the elevator door and sends out an overweight alarm signal.
Wherein the elevator controller controlling the car of the elevator to travel to the door zone of the current floor comprises: the elevator controller generates a second running curve and controls the car to run to the door zone of the current floor according to the second running curve, wherein the second running curve is opposite to the first running curve. The second operating curves of the present invention may be different at different floors and may be determined according to the actual conditions of the different floors.
The full load torque of the embodiment of the invention is obtained through a load detection self-learning stage, which is performed before the elevator starts to work normally, as shown in fig. 2.
Step S21, when the elevator is empty, controlling the elevator to run from the bottom layer to the top layer in a layer-by-layer stopping mode, controlling the elevator to run according to a first running curve in each floor starting stage, and obtaining the output torque of the traction motor as an uplink empty torque;
step S22, when the elevator is empty, controlling the elevator to run from the top floor to the bottom floor in a layer-by-layer stopping mode, controlling the elevator to run according to the first running curve in each floor starting stage, and obtaining the output torque of the traction motor as the descending empty torque;
and S23, fitting according to the uplink idle torque and the downlink idle torque of the traction motor on each floor to obtain the full-load torque of the traction motor on each floor in each direction.
In order to obtain high-precision full-load torque, the embodiment of the invention obtains the full-load torque of the elevator on all floors in a load detection self-learning stage. As shown in fig. 3, in the load detection self-learning stage of the embodiment of the invention, the elevator controller controls the elevator to stop layer by layer and run upwards in sequence by taking the floor at the bottommost layer as a starting point (i.e. after the elevator car stops at the door zone of each floor, the elevator is restarted to run upwards). When each floor is started, the elevator controller controls the elevator to run according to a first running curve, and when the driving voltage reaches a preset frequency, the output torque of the traction motor is obtained and stored as the uplink no-load torque of each floor until the elevator runs to the highest floor. At the highest floor, the elevator controller controls the elevator to move according to the first operation curve, and the elevator does not move upwards after the uplink control torque of the highest floor is obtained.
After the elevator reaches the highest floor, the elevator controller controls the elevator to start descending, and similar to the ascending process, the elevator stops layer by layer and sequentially runs downwards (namely, the elevator car stops at the door zone of each floor and then starts to run downwards). When each floor is started, the elevator controller controls the elevator to run according to a first running curve, and when the driving voltage reaches a preset frequency, the output torque of the traction motor is obtained and stored as the descending no-load torque of each floor until the elevator runs to the lowest floor. At the lowest floor, the elevator controller controls the elevator to move according to the first running curve, and the elevator does not run downwards after the uplink control torque of the lowest floor is obtained.
Referring to fig. 4, after the load detection self-learning phase is finished, the elevator controller performs fitting processing on the uplink idle torque and the downlink idle torque of each floor to obtain full-load torque. The invention takes the floor as the third floor as an example, and assumes the ascending no-load torque of the third floor as T 1 The descending idle torque is T 2 The full load torque of the third floor is calculated as follows:
and step S231, acquiring the dynamic friction torque of the elevator at each floor according to the uplink idle torque and the downlink idle torque of each floor.
Specifically, the uplink no-load torque of the third floor acquired in the load detection self-learning stage is acquired as T 1 The descending idle torque is T 2 And the dynamic friction torque of the elevator in the third floor is obtained by the following calculation formula (1):
Figure SMS_5
(1)
wherein T is 1 Is the upward idle torque, T 2 Is the descending idle torque, T f Is a dynamic friction torque.
And step S232, obtaining full-load friction torque of each floor when the elevator is fully loaded according to the dynamic friction torque and the balance coefficient of the elevator.
And after calculating the dynamic friction torque of the third building when the third building is empty, acquiring the balance coefficient of the elevator, wherein the value of the balance coefficient is set by a user. According to the dynamic friction torque and the balance coefficient, the full-load friction torque of the elevator when the elevator is fully loaded in the third floor can be calculated, and the full-load friction torque of the third floor is obtained specifically through the following calculation formula (2):
Figure SMS_6
(2)
wherein T is F Is the full friction torque, T f Is the dynamic friction torque and K is the equilibrium coefficient.
And step S233, obtaining a second torque of the traction motor at each floor according to the full friction torque, the upward no-load torque and the balance coefficient of each floor, wherein the second torque is the torque output by the motor when the elevator is full and no external friction force is influenced.
Specifically, according to the mechanical equation, the corresponding output torque at the time of no-load of third floor is (T 1 -T f ) In combination with the balance coefficient of the elevator, the second torque of the traction motor in the third building is obtained by the following calculation formula (3) under the full load state of the third building and without considering the influence of external friction force:
Figure SMS_7
(3)
wherein T is Q Is the second torque, T F Is the full friction torque, T f Is the dynamic friction torque and K is the equilibrium coefficient.
Step S234, obtaining the full load torque of each floor according to the second torque and the full load friction torque of each floor.
Specifically, the full-load torque of the third floor is obtained by the following calculation formula (4):
Figure SMS_8
(4)
wherein T is the full load torque, T Q Is the second torque, T F Is the full load friction torque. Wherein the full load torque comprises an uplink full load torque and a downlink full load torque, and the uplink full load torque TU and the downlink full load torque T of the third floor can be known according to the calculation formula (4) D Calculated according to the following calculation formula:
Figure SMS_9
(5)
according to the above formulas (1) - (5), the up full load torque and the down full idle torque of each floor can be calculated.
According to the invention, the pre-running process is added in the normal running time sequence of the elevator, and the output torque of the traction machine is obtained through the pre-running process to measure the load of the elevator; and the full-load torque of the traction machine is obtained by adding a pre-running process in a load detection self-learning stage. Under the condition of not adding a weighing sensor, the invention judges whether the elevator is overweight or not by comparing the output torque of the traction machine during normal operation with the full-load torque of the load detection self-learning stage, thereby saving the hardware cost and improving the load detection precision of the elevator.
