Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The method can be executed by the safety speed regulating device of the elevator, and can also be executed by the electronic equipment. The method for safely adjusting the speed of an elevator provided by the present application is performed by the safety speed adjusting device for an elevator provided by the present application, but the present application is not limited thereto, and the method is hereinafter simply referred to as "device".
The voltage of a power grid in China is nominally 380V, and for the deviation of power supply voltage, there is a definite statement in the national standard that the deviation of three-phase power supply voltage of 20kV and below is +/-7% of the nominal voltage, but the voltage condition is often difficult to control. In addition, the operation of the equipment is greatly influenced by the voltage fluctuation of the power grid, and the electric equipment stops working due to serious voltage sag, even more, property loss is caused, and the life safety of people is threatened. In the application, in order to enable the elevator to still operate according to a specific safe operation mode when the power supply voltage is reduced, so that emergency braking of the elevator in high-speed operation is avoided, and the condition of repair in a standby occasion is avoided, a safe speed regulation method of the elevator is provided, so that the elevator can safely operate when the voltage sag occurs, and the influence of the voltage sag on a user is reduced.
The method, the device, the computer equipment and the storage medium for safely regulating the speed of the elevator provided by the application are described in detail in the following with reference to the attached drawings.
Fig. 1 is a flow chart of a safety governing method of an elevator according to an embodiment of the present application.
As shown in fig. 1, the safe speed regulating method of the elevator may include the steps of:
and 101, acquiring an output signal of the power voltage of the current elevator.
It should be noted that the elevator is a relatively important vertical transportation device in a high-rise building, and can provide convenience for the movement of people on high floors and meet the requirement of passenger and cargo flow of the building. An elevator is a vertical elevator powered by an electric motor, and is provided with a box-shaped nacelle for riding people or carrying goods in a multi-story building, and as an important electric device, the voltage quality of the elevator also has important requirements. The traditional machine room elevator usually adopts an alternating current asynchronous motor and an alternating current variable voltage variable frequency speed regulating system, and compared with the common machine room elevator, the small machine room elevator usually adopts a gearless traction machine driven by a permanent magnet motor, and usually the elevator mostly adopts 380V alternating current without limitation.
In this application, can obtain the output signal of the mains voltage of present elevator through the voltage monitoring return circuit.
Specifically, the voltage monitoring circuit may be provided in advance on the power supply voltage monitoring circuit board, and have a plurality of threshold values, thereby enabling signal output in a wide voltage range. It should be noted that the fluctuation characteristics of the current power supply voltage can be monitored by monitoring the output signal of the current power supply voltage of the elevator, so that the current power supply voltage of the elevator can be conveniently detected in real time, and the safety of the elevator is improved.
And 102, determining a voltage interval where the power supply voltage is located according to the output signal of the power supply voltage.
It should be noted that after the output signal of the power supply voltage is determined, the CPU, that is, the upper computer, may calculate the acquired output signal of the power supply voltage, so as to determine the voltage interval where the current power supply voltage is located.
Wherein, the CPU board can be for the arithmetic device who contains a plurality of output and input interface to can satisfy the collection of a plurality of external signal, judge and the operation, in addition, output signal can be for the real-time voltage signal of optical coupling insulation output.
And 103, determining a speed adjusting mode of the elevator according to the voltage interval of the power supply voltage.
It should be noted that, in the present application, a voltage interval where the power supply voltage is located and a voltage drop degree corresponding to the power supply voltage may be determined according to the current power supply voltage, and then a current speed adjustment mode matching therewith, such as multi-stage speed adjustment, operation according to a rated speed, and the like, may be determined according to the voltage drop degree, which is not limited herein.
In this application, in order to ensure the safe operation of elevator, can divide into different adjustment modes according to current mains voltage, adjust the moving speed of current elevator to improve the stability of elevator when elevator mains voltage fluctuates.
As a possible realization, in the case of a supply voltage in the first voltage interval, the speed adjustment of the elevator is determined in such a way that the speed of the elevator is controlled to the nominal speed.
Specifically, if the current rated voltage is a, the first voltage interval may be [ 90% a-93% a ").
In addition, if the current power supply voltage is in the first voltage interval, it is described that the current power supply voltage drop has a small influence on the elevator, and therefore the current operating speed can be set to the rated speed.
As a further possible realization, in the case that the supply voltage is in the second voltage interval, the speed adjustment of the elevator is determined in such a way that the speed of the elevator is reduced according to the target reduction ratio.
Specifically, if the current rated voltage is a, the second voltage interval may be [ 85% a-90% a ].
According to the regulation of GB/T10058, the minimum speed permitted by the elevator is 92% of the rated speed when the supply voltage is at the rated voltage.
The target reduction ratio is a predetermined reduction ratio, and may be 92%, for example, without being limited thereto.
Therefore, under the condition that the power supply voltage is in the second voltage interval, the speed reduction value of the elevator can be 92% of the rated speed, and therefore the safe operation of the elevator at present can be guaranteed.
As a further possible realization, in the case that the supply voltage is in the third voltage interval, it is determined that the speed adjustment mode of the elevator is a multi-step down.
It should be noted that the voltage value of the third voltage interval is smaller than the first voltage interval and the second voltage interval, which may be [ 80% a-85% a ], and when the power supply voltage is in the third voltage interval, the speed of the elevator may be adjusted in a multi-level speed reduction manner, that is, the elevator enters a self-adaptive running state, that is, speed reduction running, so that the speed may be determined according to real-time operation data.
Alternatively, the proportional relation between the supply voltage and the nominal voltage can be determined first, after which the speed of the elevator is adjusted according to the proportional relation. It will be appreciated that the control and stepless adjustment of speed can be performed by voltage to determine a speed that matches the current supply voltage.
Optionally, when the voltage interval in which the power supply voltage is located is the fourth voltage interval, the speed adjustment mode of the elevator is determined to be that the speed of the elevator is controlled to be 0.
It should be noted that, if the current power supply voltage is in the fourth voltage interval, that is, the current power supply voltage is less than 80% of the rated voltage, the current elevator can be repaired, so that the danger can be avoided.
And 104, adjusting the speed of the elevator based on the speed adjusting mode.
It should be noted that the adjusted speed can be sent to the control end through the CPU, so that the frequency converter can adjust the speed of the elevator according to the control command of the control end, and specifically, can be executed by executing components, such as a traction machine and a motor.
Optionally, the actual position of the elevator can be calculated according to the numbers given by the rotary encoder, and the speed change position can be calculated according to the frequency conversion parameters set for realizing the speed change, or the speed regulation switch can be triggered when the elevator runs to the position needing speed change, so as to realize speed change.
In the embodiment of the application, the output signal of the power supply voltage of the current elevator is firstly acquired, then the voltage interval where the power supply voltage is located is determined according to the output signal of the power supply voltage, then the speed adjusting mode of the elevator is determined according to the voltage interval where the power supply voltage is located, and finally the speed of the elevator is adjusted based on the speed adjusting mode. The speed adjusting mode of the elevator is determined according to the current interval of the power supply voltage, so that the application range of the power supply voltage can be enlarged, the elevator can run at a reduced speed on the occasion of voltage sag, the elevator using requirements of customers can be met, and the safety of elevator operation can be improved.
