An elevator is one which serves a number of specific floors within a building and whose cars are operated in at least two rows at a vertical level or at an inclination angle of less than 15 with respect to the plumb line 0 A permanent transport device for rigid rail movement; in modern high-rise buildings, elevators become second largest energy consumption equipment of the high-rise buildings which are inferior to air conditioners, and energy conservation and consumption reduction of the elevator equipment become one of important links of energy conservation and emission reduction. The existing goods elevator needs to ensure unloading continuity in the process of loading goods and ensures that an elevator door is continuously opened, so that the body is generally adopted to block an elevator identification light curtain or a door opening button is frequently pressed, and the health of a person can be influenced; during the continuous opening period of the elevator door, a lighting system, an air conditioning system and the like in the elevator car are in a continuous working state, so that a large amount of electricity is wasted, and energy conservation and environmental protection are not facilitated.
Based on the above, the embodiment of the application provides an elevator hovering energy management method and a related device, so as to solve the above problems. The embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a schematic architecture diagram of an elevator hovering energy management system provided in an embodiment of the present application, as shown in fig. 1, an elevator hovering energy management system 10 includes an elevator energy feedback system 110 and an elevator 120, where the elevator energy feedback system 110 is configured to obtain additional mechanical energy generated by the elevator 120 during operation, convert the additional mechanical energy into electrical energy according to a traction device, and obtain usable feedback electrical energy after a series of modulations;
the elevator 120 includes a car 121, a counterweight 122 and an internal power device 123, wherein the counterweight is a load block provided for balancing the operation of the elevator, and the weight of the counterweight is about 50% of the maximum operation load of the elevator, and the internal power device is a power device working in the car 121, and is mainly used for users riding the elevator, and it should be understood that the internal power device is not necessary for the operation of the elevator, and the adjustment power strategy can be properly closed for saving energy.
Referring to fig. 2, fig. 2 is a schematic flow chart of an elevator hovering energy management method according to an embodiment of the present application, which is applied to an elevator energy feedback system 110 in the elevator hovering energy management system 10 shown in fig. 1; the method comprises the following steps:
Step S201, the control elevator runs to the first destination floor.
Specifically, the control system of the elevator receives a running instruction from the first destination floor, such as pressing a down button.
And step S202, after the elevator reaches the first target floor, recording the loading time of loading the goods into the elevator by a user and the loading weight of the goods by the user.
The elevator door entrance is provided with an image sensor, the starting time of a user or goods entering the elevator car is recorded, the ending time of the user and the goods completely entering the elevator car is detected through the image sensor, and the time period is taken as the loading time period.
After the user and the cargoes completely enter the elevator car, the load weight of the user and the cargoes is detected through the elevator self-carried load testing device, specifically, the number of the user and the cargoes is not limited, and the load weight cannot exceed the maximum load bearing of the elevator due to safety consideration.
And step 203, in response to an operation instruction indicating the elevator to operate from the first target floor to the second target floor, estimating the unloading duration of the elevator after reaching the second target floor according to the loading duration when the loading weight is determined to be greater than the weight of the counterweight of the elevator.
Wherein the number of floors of the first destination floor is greater than the number of floors of the second destination floor; specifically, the operation instruction refers to operation from a high floor to other floors lower than the high floor in the application, and meets the operation condition of elevator energy feedback.
In particular, the weight of the counterweight is typically about 50% of the maximum load bearing of the elevator, it being understood that downward movement of the car will result in a loss of mechanical energy from the system when the load weight is greater than the weight of the counterweight, thereby providing for elevator energy feedback.
Wherein, the loading time length is related to the unloading time length, the loading time length can be slightly larger or slightly smaller than the unloading time length, the loading time length and the unloading time length cannot be excessively different, and the ratio range of the loading time length and the unloading time length can be estimated according to the actual scene, for example, 0.8-1.2.
And step S204, determining the total expected power consumption according to the unloading duration and the rated power of target power equipment of the elevator.
The target power equipment is a plurality of power equipment working in the elevator car.
Specifically, according to the electric power calculation formulaIt is known that the discharge duration T is multiplied by the rated power P of the target power equipment Total (S) Obtaining the total estimated power consumption W Total (S) 。
And step S205, determining feedback electric energy generated in the running process of the elevator according to the load weight and the running distance between the first target floor and the second target floor.
Wherein, according to the gravitational potential energy formulaIt can be seen that when the elevator is running, the gravitational potential energy disappeared by the system of the physical layer is that the weight m of the load is multiplied by the running distance h, and then the gravitational constant g is added. It should be understood that there is still kinetic energy conversion in the actual elevator operation, for example the kinetic energy is suddenly increased from 0 when the elevator starts, and the kinetic energy is unchanged when the elevator is traveling at a uniform speed, and the elevator is decelerating when reaching the second destination floor, and the kinetic energy is lost at this time, and meanwhile, because the load weight of the current scene is large, the kinetic energy in the energy conversion process of the system is negligible.
Wherein the disappearance can be considered asThe gravitational potential energy of (2) is converted into feedback electric energy, and partial loss can also exist, such as circuit heating loss, loss in the transmission process, etc., a reference coefficient such as 0.7 can be added as a loss reference coefficient, and the feedback electric energy W is obtained by multiplying the lost gravitational potential energy by the loss coefficient And (5) returning.
And step S206, if the feedback electric energy is greater than or equal to the total expected electric energy, acquiring the feedback electric energy and selecting the feedback electric energy as the working electric energy of the target power equipment after the elevator reaches the second target floor.
It can be seen that in this example, the elevator is first controlled to run to the first destination floor; after the elevator reaches the first target floor, recording the loading time of loading cargoes by a user into the elevator and the loading weight of the cargoes by the user; when the loading weight is determined to be greater than the weight of the counterweight of the elevator in response to an operation instruction indicating the elevator to operate from the first target floor to the second target floor, estimating the unloading time of the elevator after reaching the second target floor according to the loading time; determining total predicted electricity consumption according to the unloading duration and rated power of target power equipment of the elevator; determining feedback electric energy generated in the running process of the elevator according to the load weight and the running distance between the first target floor and the second target floor; and if the feedback electric energy is larger than or equal to the total predicted electricity consumption, acquiring the feedback electric energy and selecting the feedback electric energy as the working electric energy of the target power equipment after the elevator reaches the second target floor. Therefore, electric energy is provided for electric equipment in the elevator car in the elevator hovering process, meanwhile, safety of a user for carrying goods through the elevator is guaranteed, electric energy is saved, and user riding elevator experience is optimized.
In one possible example, in step S204, the target power device includes at least one of the following: communication equipment, lighting equipment and ventilation equipment; the method for determining the total estimated power consumption according to the unloading duration and the rated power of the target power equipment of the elevator comprises the following steps:
multiplying rated power of a plurality of devices in the target power device by the unloading duration to obtain a plurality of corresponding expected power consumption of the devices, wherein the expected power consumption of the devices comprises: the communication equipment predicts the electricity consumption, the lighting equipment predicts the electricity consumption and the ventilation equipment predicts the electricity consumption;
and adding the estimated power consumption of the communication equipment, the estimated power consumption of the lighting equipment and the estimated power consumption of the ventilation equipment to obtain the total estimated power consumption.
Specifically, a communication device such as an alarm device provided in the car of an elevator that communicates to an elevator manager when an emergency is encountered; the lighting equipment comprises a plurality of bulbs in the elevator car, and other electronic equipment with built-in LEDs, bulb components, such as billboards, luminous buttons and the like; the ventilation device is a fan device for maintaining the circulation of air inside the elevator car and an air conditioning device for maintaining a proper temperature.
Wherein, according to the electric power calculation formulaIt is known that the communication device is expected to use power +.>The same holds that the lighting device is expected to consume the electricity W Illumination device Estimated power consumption W of ventilation equipment Wind power Thus, it is known that:。
in a possible example, referring to fig. 3, fig. 3 is a schematic flow chart of a power supply strategy provided in an embodiment of the present application, as shown in fig. 3, in step S205, after determining feedback electric energy generated by the elevator during operation, the method further includes the following steps S301 to S307:
step S301, if the feedback electric energy is smaller than the total predicted electric energy consumption, setting a power supply priority for the target electric power equipment.
The power supply priority is used for indicating the order of priority power supply in the target power equipment, wherein the power supply priority of the communication equipment is larger than the power supply priority of the lighting equipment, and the power supply priority of the lighting equipment is larger than the power supply priority of the ventilation equipment.
Step S302, comparing the feedback electric energy with the predicted electric energy consumption of the communication equipment according to the sequence indicated by the power supply priority, and skipping according to the comparison result; if the feedback power is greater than or equal to the predicted power consumption of the communication device, the step S303 is skipped; if the feedback power is smaller than the predicted power consumption of the communication device, the process goes to step S307.
