All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

It should be noted that all directional indicators (such as up, down, left, right, front, and back \8230;) in the embodiments of the present invention are only used to explain the relative positional relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicators are changed accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

At present, in the field of elevators, a common frequency converter achieves the effect of reducing energy consumption, for example, energy conservation is achieved by calculating appropriate acceleration and speed through the lifting height of an elevator every time, but the energy-saving process of the frequency converter often conflicts with the carrying requirement, and particularly in the peak period of people flow, the frequency converter can affect the operation efficiency of the elevator on the contrary, so that the frequency converter can only meet the energy conservation but cannot give consideration to the operation efficiency of the elevator.

The invention provides an improved elevator control method for solving the technical problem of energy waste of an elevator.

The technical effects that can be achieved based on the above description are:

the gear of the elevator is adjusted by obtaining the passenger flow volume and the evaluation index of the running condition of the elevator in the adjacent two running processes, and the energy saving effect can be realized due to different energy consumption brought by different gears. And because the evaluation index is obtained according to the passenger flow and the running time parameters of the elevator, the influence factors of the passenger flow and the running condition of the elevator are measured, and the evaluation index belongs to real-time statistical data, so that the evaluation index can be reflected no matter in the peak period of the passenger flow or in the rare period of the passenger flow, and the evaluation index can give consideration to the factors of the passenger flow and the running efficiency of the elevator, and the elevator is more accurately and adaptively controlled to save energy.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The first embodiment is as follows:

fig. 1A is a flow chart illustrating an embodiment of an elevator control method according to an exemplary embodiment of the present invention, in which a sensor is installed in an elevator to identify the number of people carried in the elevator, for example, the sensor may be a camera. As shown in fig. 1A, the elevator control method includes the steps of:

step 101: and obtaining the passenger flow volume and the evaluation index of the running condition of at least one elevator in the adjacent two running processes according to the passenger flow volume and the running time parameters of the elevator.

The run time parameters may include, among other things, the time of receipt of the call command, the end time of the run to the terminal floor, etc.

In this embodiment, the one-time running process of the elevator means that the call command is received to the starting floor where the call command is triggered when no person is in the elevator, and the one-time running process is finished from the time when the person enters the elevator to the end floor. The terminal floor refers to the highest floor or the lowest floor obtained by a person entering the elevator triggering operation box, if the elevator ascends, the terminal floor is the highest floor obtained by triggering the operation box, and if the elevator descends, the terminal floor is the lowest floor obtained by triggering the operation box.

Furthermore, the evaluation indexes of the passenger flow and the running condition of the two adjacent running processes of the elevator are scalar quantities used for measuring the influence factors of the passenger flow and the running condition of the elevator, and the higher the value of the evaluation indexes is, the higher the current passenger flow and the running degree of the elevator are.

In an alternative embodiment, the fewer the number of evaluation indicators obtained, the more frequent the adjustment of the elevator, e.g. once for each evaluation indicator obtained for two consecutive runs of an elevator. In order to reduce frequent changes of the elevator, 3 adjacent evaluation indexes can be acquired each time for adjusting the elevator.

That is, the evaluation indexes of the passenger flow volume and the operation condition of the first operation process and the second operation process of the elevator, the evaluation indexes of the passenger flow volume and the operation condition of the second operation process and the third operation process of the elevator, and the evaluation indexes of the passenger flow volume and the operation condition of the third operation process and the fourth operation process of the elevator are taken as 3 adjacent evaluation indexes.

It should be further noted that, for the process of obtaining the evaluation indexes of the passenger flow volume and the operation condition in the two adjacent operation processes of the elevator, reference may be made to the following description of embodiments, which is not detailed herein for the moment.

Step 102: and determining the gear required to be operated by the elevator according to the acquired at least one evaluation index.

Before step 102 is executed, a corresponding relationship between an evaluation index interval and a gear needs to be preset, in this embodiment, the evaluation index is actually a ratio between a real-time passenger flow transportation capacity requirement and a preset passenger flow peak transportation capacity requirement, and the preset passenger flow peak transportation capacity requirement is a percentage of a passenger flow that can be transported by a single elevator or a group of elevators in a given time period (for example, 5 minutes) obtained according to elevator type selection and configuration standard requirements.

Therefore, if the evaluation index is larger than 1, the requirement of the real-time passenger flow volume transportation capacity exceeds the preset requirement of the passenger flow peak transportation capacity, and if the evaluation index is smaller than 1, the requirement of the real-time passenger flow volume transportation capacity does not exceed the preset requirement of the passenger flow peak transportation capacity. Therefore, at least two gears need to be divided to meet the adjustment requirement of the elevator, namely, the evaluation index is in two intervals of more than 1 and less than 1.

Of course, in order to realize more fine adjustment of the operation efficiency of the elevator, a plurality of evaluation index intervals can be additionally divided according to actual requirements.

As shown in table 1 below, the evaluation index is divided into five sections, i.e., 1 or more, 0.8 to 1, 0.6 to 0.8, 0.4 to 0.2, and 0.2 or less, so that each evaluation index corresponds to one elevator operation efficiency level, i.e., gear.

As can be seen from table 1, the higher the shift position is, the higher the corresponding evaluation index is.

Level of elevator operating efficiency	Five-gear	Four-gear	Three-gear	Second gear	First gear
						Evaluation index section	1 or more	0.8～1	0.6～0.8	0.4～0.2	0.2 or less

TABLE 1

Based on the above description, in an alternative embodiment, referring to fig. 1B, a process for determining a gear position of an elevator to be operated according to at least one evaluation index includes:

step 1021: and determining the gear corresponding to each evaluation index in at least one evaluation index according to the corresponding relation between the evaluation index interval and the gear.

Step 1022: and if the gear corresponding to each evaluation index is the same, determining the gear as the gear which needs to be operated by the elevator.

If the gears corresponding to each evaluation index are the same, the elevator is required to be positioned under the gear, and the requirement of the current conveying capacity can be met.

Step 1023: and if the gear corresponding to each evaluation index is smaller than the current running gear of the elevator, determining the gear lower than the current running gear of the elevator as the gear required to be run by the elevator.

If the gear corresponding to each evaluation index is smaller than the current operation gear of the elevator, the conveying capacity provided by the current operation gear of the elevator is shown to exceed the currently required conveying capacity, and the problem of resource waste exists.

Optionally, the gear obtained by reducing the current operating gear of the elevator by one gear may be used as the gear required to operate the elevator, and of course, any one of the gears corresponding to each evaluation index that is lower than the current operating gear of the elevator may also be used as the gear required to operate the elevator.

Step 1024: and if the gear corresponding to each evaluation index is larger than the current running gear of the elevator, determining the gear higher than the current running gear of the elevator as the gear required to be run by the elevator.

If the gear corresponding to each evaluation index is larger than the current running gear of the elevator, the conveying capacity provided by the current running gear of the elevator is indicated, the currently required conveying capacity is not achieved, and the problems of crowded flow and low running efficiency of the elevator exist.

Optionally, the gear after the current operating gear of the elevator is increased by one gear may be used as the gear that the elevator needs to operate, and of course, any one of the gears corresponding to each evaluation index that is higher than the current operating gear of the elevator may also be used as the gear that needs to operate.

Based on the description, the gear condition of each evaluation index is integrated to determine the gear required to be operated by the elevator, so that the conveying capacity required at present can be accurately and adaptively met.

Step 103: and adjusting the running state of the elevator and the running states of all electrical equipment in the elevator according to the gears needing to run.

In an alternative embodiment the operating state of the elevator can comprise the operating speed. The running states of all electrical equipment in the elevator comprise an air conditioner temperature state, an elevator illumination brightness state, a running mode of an elevator ventilation and disinfection system and the like.

As shown in table 2 below, the elevator operation state and the operation state control request of each elevator device are set for each gear.

TABLE 2

Those skilled in the art will understand that the above table 2 is only an exemplary illustration, and does not form a specific limitation to the solution of the present invention, and it is also possible to add a hierarchical control of other electrical devices in the elevator according to the operation requirement of the elevator.

So far, the elevator control flow shown in fig. 1A is completed, the gear of the elevator is adjusted by obtaining the passenger flow volume and the evaluation index of the running condition of the elevator in the adjacent two running processes, and the energy consumption brought by different gears is different, so that the energy-saving effect can be realized. And because the evaluation index is obtained according to the passenger flow and the running time parameters of the elevator, the influence factors of the passenger flow and the running condition of the elevator are measured, and the evaluation index belongs to real-time statistical data, so that the influence factors can be reflected in the evaluation index no matter the elevator is in a peak period of passenger flow or in a rare period of passenger flow, the evaluation index can give consideration to the factors of the passenger flow and the running efficiency of the elevator, and the elevator can be more accurately controlled in an energy-saving manner.

Example two:

fig. 2A is a schematic flow chart illustrating a process of determining passenger flow and evaluation index of operating conditions in two adjacent elevator operating processes according to an exemplary embodiment of the present invention, and based on the embodiment illustrated in fig. 1A, the process of determining passenger flow and evaluation index of operating conditions in two adjacent elevator operating processes includes the following steps:

step 201: and obtaining the passenger flow of the starting time in the current running process of the elevator.

Wherein the passenger flow refers to the number of people entering the elevator at the starting time of the operation process.

In an optional specific embodiment, after the elevator is detected to be opened and closed at the starting floor carried by the second call command, the number of people existing in the elevator is identified, so that the identified number of people is determined as the passenger flow at the initial time in the running process.

The second call command refers to a command that the operation process needs to be executed, and the second call command carries a call floor, namely a floor triggered by a user.

Step 202: and when the elevator runs to the terminal floor of the running process, acquiring the receiving time of a first call command needing to execute the next running process.

The terminal floor refers to the highest floor or the lowest floor obtained when a person enters the elevator triggering control box, if the elevator running process is an ascending process, the terminal floor is the highest floor obtained by triggering the control box, and if the elevator running process is a descending process, the terminal floor is the lowest floor obtained by triggering the control box.

It should be noted that the terminal floor may be the highest or lowest floor triggered by a passenger entering the elevator at the starting time of the elevator present-time operation process, or may be the highest or lowest floor triggered by a passenger entering the elevator at a certain floor in the elevator present-time operation process.

For example, if the elevator is started to move upwards from one floor in the current operation process, the highest floor triggered by a passenger entering the elevator at one floor is 7 floors, the terminal floor of the current operation process is determined to be 7 floors, when the elevator moves to 3 floors, a call command of 5 floors is received, the elevator driving direction indicated by the call command is upward, when the elevator moves to 5 floors, the door is opened and closed, and if the floor triggered by the passenger entering the elevator at 5 floors is 10 floors, the elevator needs to update the terminal floor of the current operation process to be 10 floors.

It should be further explained that the elevator driving direction indicated by the first call command of the next operation process needs to be executed is opposite to the elevator driving direction of the current operation process.

It is noted that the time of receipt of the first call command acquired to execute the next trip may be earlier than the end time of the terminal floor of the current trip or later than the terminal floor to the end time.

For example, assuming that the terminal floor of the elevator in the current operation process is 10 floors and the traveling direction is an upward direction, if the elevator travels to 7 floors, a person calls 8 floors and the calling direction is a downward direction, so that the elevator does not reach the terminal floor of the current operation process, a first call command which needs to be executed in the next operation process is received, and the receiving time of the first call command which needs to be executed in the next operation process is earlier than the ending time of the terminal floor of the current operation process.

If a person calls 8 floors after the elevator runs to the 10 floors of the terminal floor in the running process, and the calling direction is downward, the receiving time of the first calling command needing to be executed in the next running process is later than the ending time of the terminal floor in the running process.

It will be understood by those skilled in the art that the first and second call commands described above are only call commands that distinguish between different runs.

Step 203: and determining the time difference of the adjacent two running processes of the elevator according to the receiving time of the first call command.

The time difference can reflect the current use frequency of the elevator by the passenger, the longer the time difference is, the lower the current use frequency of the elevator by the passenger is, and the shorter the time difference is, the higher the current use frequency of the elevator by the passenger is.

In an alternative embodiment, referring to fig. 2B, the process for determining the time difference between two adjacent elevator runs includes:

step 2031: and acquiring the end time of the elevator running to the terminal floor of the running process.

Wherein the end time refers to the time after the elevator has run to the terminal floor and the door is opened.

Step 2032: the time difference is set to a preset value if the time of receipt of the first call command is earlier than the end time of the terminal floor.

If the receiving time of the first call command is earlier than the end time of the terminal floor, the first call command which needs to execute the next operation process is received in the operation process of the elevator, the use frequency of the elevator currently by passengers is high, and the time difference hardly exists in the adjacent two operation processes, so that the time difference is set as a preset value.

Optionally, the unit of the time difference may be seconds, and the preset value is 1 second.

Step 2033: if the time of receipt of the first call order is later than the terminal floor to the end time, the difference between the time of receipt of the first call order and the end time of the terminal floor is determined as said time difference.

If the receiving time of the first call command is later than the time from the terminal floor to the terminal floor, the fact that the first call command needing to be executed in the next running process is received after the elevator executes the running process is shown, the situation shows that the time difference exists between the two adjacent running processes, and therefore the difference between the receiving time of the first call command and the terminal floor is taken as the time difference.

Based on the description, the accurate time difference between two adjacent running processes can be given by comparing the end time of the elevator running to the terminal floor of the running process with the receiving time of the first call command of the next running process.

It should be noted that, in order to avoid resource waste caused by long-time unattended calling after the elevator executes the operation process, the current operation gear of the elevator can be reduced step by step.

The specific implementation process is as follows: when the elevator runs to the terminal floor of the running process, the first call command which needs to be executed in the next running process is not received, timing is started, when the timing reaches a preset time interval, the current running gear of the elevator is lowered by one gear, the timing is reset, then timing is restarted, and the timing is stopped until the first call command which needs to be executed in the next running process is received, so that the resource waste can be further reduced.

Optionally, the preset time interval is 5 minutes, that is, each time the timing time interval reaches 5 minutes, the current operating gear of the elevator is lowered by one gear.

Step 204: and determining the evaluation indexes of the passenger flow and the running condition according to the time difference and the passenger flow.

In an optional specific embodiment, the time difference and the passenger flow volume may be used to determine a real-time passenger flow volume transportation capacity requirement, and then the passenger flow volume and the evaluation index of the operation condition of the elevator in two adjacent operation processes are determined according to the real-time passenger flow volume transportation capacity requirement and a preset passenger flow peak transportation capacity requirement.

The calculation formula of the real-time passenger flow volume transportation capacity requirement is as follows:

wherein A represents the passenger flow volume, B represents the time difference, N _P The number of elevator design service headquarters is shown, and C is the real-time passenger flow capacity requirement.

According to the requirements of elevator type selection and configuration standard, the calculation formula of the requirement of the transport capacity in the peak period of passenger flow is as follows:

wherein, P represents the average passenger number of the elevator in the peak period of passenger flow, 80 percent of the rated passenger number is determined by the area of the lift car, the known quantity is taken, INT represents the average value, the known quantity and N of the time interval between two adjacent departures from the base station in the peak period of passenger flow _P The number of elevator design service headquarters is shown, and HC shows the demand for capacity at peak periods of passenger flow.

The calculation formula of the evaluation indexes of the passenger flow and the running condition in the two adjacent running processes of the elevator is as follows:

as can be seen from equation 3, since INT and P are known quantities, the magnitude of the evaluation index D is determined by the passenger flow volume a and the time difference B.

Therefore, the evaluation index determination process shown in fig. 2A is completed, by obtaining the passenger flow at the starting time in the current operation process of the elevator and the time difference between two adjacent operation processes of the elevator, because the complexity of the calculation logic is considered, the passenger flow at the starting time in the current operation process can reflect the current passenger flow situation to a certain extent, and the time difference between two adjacent operation processes can reflect the current frequency situation of the elevator used by the passenger, the evaluation index determined by the obtained passenger flow at the starting time and the time difference between two adjacent operation processes can weigh two influencing factors of the passenger flow and the elevator operation situation, and the calculation logic is simple and feasible.
