Referring to fig. 1 and 2, fig. 1 illustrates an elevator group management method according to the present application. The elevator group management method comprises the following steps:
and S100, judging whether the elevator group 10 is in a self-generating state or not. Referring to fig. 2, an elevator group management system 100 is provided that includes the elevator group 10 and a group management cabinet 20. The elevator group management system 100 may be installed in office buildings, hotels, apartments and department stores. The elevator group 10 includes at least one elevator 11, and can freely move up and down between floors from the lowest floor (one floor, one floor minus, two floors minus, three floors minus, etc.) to the highest floor. The plurality of elevators 11 are controlled in a united manner by the group management cabinet 20. Typically, the elevator group management system 100 is powered by the building's power supply system. In special situations, such as a power outage or a line repair between buildings, power is supplied from the power generation equipment of the elevator group management system 100. In this step, it is determined whether the elevator group 10 is in a self-generating state, that is, whether the elevator group management system 100 is in a self-generating state or a power failure state. The specific judgment process may be the judgment or monitoring implemented by the group management cabinet 20.
And S200, if the elevator group 10 is in the self-generating state, switching the operation mode of the elevator group 10 to a specific elevator group management operation mode. In the specific elevator group management operation mode, no matter whether the communication between the elevator groups 10 is normal or not, the elevator group 10 can complete the safe operation of the elevator group 10 according to the preset controlled operation sequence of the elevators and the starting time of different elevators in the elevator group 10. In this step, switching of the operation mode of the elevator group 10 is mentioned. Specifically, the operation modes of the elevator group 10 may be a normal operation mode, a holiday operation mode (higher frequency of use than the normal operation mode and more sensitive scheduling), a power-saving operation mode (lower frequency of use than the normal operation mode, and a slightly longer response time or a slightly slower operation speed) and a specific elevator group management operation mode. The particular group management mode of operation includes: the preset controlled operation sequence of the elevators and the starting moments of the different elevators in said elevator group 10 are determined. In the particular group management operation mode, the operation start-up sequence and the start-up time of each of the elevators 11 are determined. For example, in the specific elevator group management operation mode, the possible starting sequence is that the second elevator is started first, the third elevator is started second, the fourth elevator is started third, and the first elevator is started fourth. The respective starting moments of the four elevators are also determined. For example, the second elevator is started at the time when the specific group management operation mode is on (the starting time of the second elevator is T0), the third elevator is started at the time T1 after the specific group management operation mode is on (T1 is a numerical value greater than zero), the fourth elevator is started at the time T2 after the specific group management operation mode is on (T2 is a numerical value greater than T1), and the first elevator is started at the time T3 after the specific group management operation mode is on (T3 is a numerical value greater than T2).
In this embodiment, an elevator group management method is provided, which can switch an operation mode of an elevator group 10 to a specific elevator group management operation mode after determining that the elevator group 10 is in a self-generating state, so as to enable each elevator 11 in the elevator group 10 to be started according to a preset control operation sequence of each elevator. After the elevator group 10 is judged to be in the self-generating state, the elevator group management method can still realize the control operation of the elevator group 10 even if the information is exchanged (communication is interrupted) among the elevators. Or, in the specific elevator group management operation mode, no matter whether the communication between the elevator groups 10 is normal or not, the elevator group 10 can complete the safe operation of the elevator group 10 according to the preset controlled operation sequence of the elevators and the starting time of different elevators in the elevator group 10. In the elevator group 10, in the specific elevator group management operation mode, the starting times of different elevators in the elevator group 10 are different, so that the elevator line load is not too large, and the dangerous situation of elevator operation is avoided. The elevator group management method can efficiently convey passengers to the refuge layer, improves the convenience of the passengers, and reduces the safety risk of the elevator.
In one embodiment, the specific steps after the elevator group 10 switches to the particular group management mode of operation include:
s210, according to the preset controlled operation sequence of the elevators, a first elevator starts to operate, and the controlled operation time of the first elevator is controlled.
And S220, after the controlled operation of the first elevator is finished, the second elevator starts to operate according to the preset controlled operation sequence of the elevators, and the controlled operation time of the second elevator is controlled.
And S230, operating other elevators in the elevator group 10 except the first elevator and the second elevator according to the steps of S210-S220 until all elevators in the elevator group 10 finish operating or the specific elevator group management operation mode is exited. The starting operation time of each elevator in the elevator group 10 depends on the clock of the elevator, so that the elevator group 10 can realize normal control operation when communication is abnormal.
Specifically, the steps of S210-S230 described above may be understood as determining the first elevator according to a preset controlled operation sequence of the elevators.
The starting moment t1 of the first elevator is further determined. The starting time t1 of the first elevator may be a time when the elevator group 10 is switched to the specific elevator group management operation mode, or may be several seconds after the elevator group 10 is switched to the specific elevator group management operation mode.
The managed operating time t of the first elevator is determined. The controlled operating time t of the first elevator may be calculated from a rated operating speed of the first elevator, a lowest operating speed of the first elevator, a car weight of the first elevator, and a distance between a floor where an event occurs (generally, a highest floor) and a refuge floor (generally, a floor). In one embodiment, during the time period of (t1, t1+ t), only the first elevator may be operated. In another embodiment, other elevators may also be operated during the time period of (t1, t1+ t), if the capacity permits.
And determining a second elevator according to the control operation sequence of the preset elevator.
The starting moment t2 of the second elevator is further determined. The starting time t2 of the second elevator may be a time when the second elevator control operation ends, and t2 is t1+ t. At a time Δ t after the time point when the second elevator control operation ends, t2 may be t1+ t +/Δ t.
The managed run time t' of the second elevator is determined. The controlled operation time t' of the second elevator can be calculated according to the rated operation speed of the second elevator, the lowest operation speed of the second elevator, the weight of the second elevator car and the distance between the floor where the event occurs (the highest floor is generally selected) and the refuge floor (the first floor is generally selected). The control operating time t' of the second elevator may be equal to the control operating time t of the first elevator. In one embodiment, only the second elevator is operated during the time period of (t2, t2+ t'). In another embodiment, other elevators can also be run during the time period of (t2, t2+ t'), if the capacity permits.
The first elevator is provided with a first timer for calculating the starting time t1 and the controlled operation time t. Timer t2 a second timer for counting the starting time t2 and the controlled running time t' is provided in the second elevator, and so on, so that each elevator 11 can be started to run according to its own timer even if the communication between the elevators 11 in the elevator group 10 fails.
And pushing according to the steps until all the elevators in the elevator group 10 finish running or the elevator group 10 exits the specific elevator group management running mode.
In this embodiment, specific operation steps after the elevator group 10 is switched to the specific elevator group management operation mode are provided. According to the steps in the embodiment, after the elevator group 10 is in a self-generating state, even if information cannot be exchanged among the elevators, the controlled operation of the elevator group 10 can still be realized. In the elevator group 10, in the specific elevator group management operation mode, the starting times of different elevators in the elevator group 10 are different, so that the elevator line load is not too large, and the dangerous situation of elevator operation is avoided. The elevator group management method can efficiently convey passengers to the refuge layer, improves the convenience of the passengers, and reduces the safety risk of the elevator.
In one embodiment, the particular elevator group management mode of operation further comprises: and controlling the elevator to run according to the control running time, so that the elevator runs from the floor to the refuge floor. In this embodiment, considering that there may be a faulty elevator in the elevator 11, the execution process of the faulty elevator is assumed and estimated in advance to a certain extent, so as to avoid the occurrence of a phenomenon that passengers are trapped in the faulty elevator. For example, if the fault elevator is on a flat floor, a door opening command is output to the fault elevator. And if the fault elevator is in operation, controlling the nearest floor of the fault elevator to stop the elevator and outputting a door opening instruction. And if the fault elevator cannot run, continuously maintaining the current state.
In this embodiment, the refuge layer is generally a single layer. In the embodiment, in the process of the controlled operation of the elevator, voice can be broadcasted to prompt passengers that the elevator is in a safe operation state at present. For example, when the elevator starts to enter the controlled operation stage, a voice "sorry very, now the elevator is in the emergency use state, and you are transported to one floor (or the refuge floor)" is broadcast. When the elevator runs to the refuge layer safely, the voice is further broadcasted to ' please leave the elevator in time, go to the safe area and thank you for ' coordination '.
In one embodiment, the managed run time is equal to the total building height divided by the elevator run speed plus the reserved time. In this embodiment, the reserved time may be 0 second to 30 seconds. The reserved time may be calculated as the minimum time for the regulated operation of the elevator with reference to the nominal operating speed of the elevator, the lowest operating speed of the elevator, the weight of the elevator car and the floor on which the event occurred (which may be the highest floor or other floors in between). On the basis of this minimum time, plus the reserve time equals the actual managed run time of the elevator. The controlled operation time is not necessarily set to a fixed value, and may be set to an extended time corresponding to the shortest time for controlled operation of the elevator, or may be adjusted reasonably according to date information or work and rest time, for example. In a specific embodiment, the regulated run time is equal to the total building height divided by the elevator run speed plus a reserved time of 10 seconds.
In one embodiment, the particular elevator group management mode of operation further comprises: and if the elevator does not run to the refuge layer in the control running time, controlling the elevator to stop and open the door at the nearest floor. In this embodiment, a security measure is provided. And if the elevator does not run to the refuge layer within the control running time, the elevator is controlled to stop at the nearest floor and open the door, and meanwhile, passengers can be prompted to get off the elevator by voice. In this embodiment, even if the elevator does not run to the evacuation layer in the controlled operation time, passengers in the elevator car are not trapped, and it is ensured that the next elevator can be controlled to run in sequence, so that the elevator group 10 has sufficient electric power to start the controlled operation.
In one embodiment, before the operation mode of the elevator group 10 is switched to the specific elevator group management operation mode, a synchronous clock signal is sent to the elevator group in real time, so that the clock of each elevator in the elevator group 10 is in a calibration state at ordinary times, and when communication between each elevator in the elevator group 10 is abnormal, the clocks on which each elevator calculates the starting time are consistent. In this embodiment, before the operation mode of the elevator group 10 is switched to the specific elevator group management operation mode, the clocks of all elevators in the elevator group 10 may be synchronized, so that the elevator group 10 can have a uniform clock in the specific elevator group management operation mode. In the actual operation process, the starting time of different elevator serial numbers in the elevator group 10 is controlled by the real-time clock of each elevator. In this embodiment, the real-time clock of each elevator is synchronized by the synchronization clock signal, and has a uniform time. The real-time clocks of the elevators in the elevator group 10 are synchronized by the synchronous clock signals and always in a mutually calibrated state, and the time uniformity is very reliable.
Referring to fig. 2, 3 and 4, fig. 2 provides an elevator group management system 100. The elevator group management system 100 includes: an elevator group 10 and a group control cabinet 20.
The group control cabinet 20 is the general controller of the elevator group management system 100. The group control cabinet 20 is used to obtain information about the elevator group 10.

The relevant information obtained by the group control cabinet 20 includes the location/floor where each elevator 11 is located, whether the communication network between the group control cabinet 20 and each elevator 11 is normal, and whether the communication network between the group of elevators 10 or each elevator 11 is normal. The group control cabinet 20 can also obtain the current operating state of the elevator group 10, such as the current operating state of the elevator group 10 in normal power supply, or the current operating state of the elevator group 10 in self-power generation.
The elevator group 10 includes a plurality of elevators 11. As shown in fig. 3, each elevator 11 includes: car body 110, timer 120 and processor 130. The timers 120 are each communicatively coupled to the processor 130.

The controller decodes and registers the instruction and completes specified operations, namely instruction control, time sequence control and operation control, according to the instruction requirement. The registers are used to store operands, intermediate data, and result data.
The elevator group management system 100 can provide a control operation mode when the group management communication is normal, and simultaneously establishes a control operation mode when the group management communication fails, so that the control operation of the group control group elevators can be realized even if the elevators cannot communicate with each other to exchange information.
In this embodiment, after the group management cabinet 20 in the elevator group management system 100 determines that the elevator group 10 is in the self-generating state, the operation mode of the elevator group 10 is switched to a specific elevator group management operation mode, so that the elevators 11 in the elevator group 10 are started according to the preset control operation sequence of the elevators. After the elevator group management system 100 determines that the elevator group 10 is in the self-generating state, even if information cannot be exchanged between the elevators, the elevator group management system can still control the operation of the elevator group 10. In the elevator group 10, in the specific elevator group management operation mode, the starting times of different elevators in the elevator group 10 are different, so that the elevator line load is not too large, and the dangerous situation of elevator operation is avoided. The elevator group management method can efficiently convey passengers to the refuge layer, improves the convenience of the passengers, and reduces the safety risk of the elevator.

In this embodiment, the synchronous clock control device 21 in the group control cabinet 20 works in cooperation with the timer 120, so that the elevator group management system 100 can have a synchronous, reliable and stable time system. In this embodiment, before the operation mode of the elevator group 10 is switched to the specific elevator group management operation mode, the clocks of the timers 120 of all the elevators 11 in the elevator group 10 are synchronized, so that the elevator group 10 can have a uniform clock in the specific elevator group management operation mode.
Referring to fig. 4, in an embodiment, the group control cabinet 20 further includes: the program setting means 22 is operated.

In this embodiment, the operating program setting device 22 may also prestore other management modes, which is not described herein. In addition, reference is made to the above-mentioned description of the elevator group management method with regard to the determination of the preset controlled operation sequence of the elevators in the operation program setting device 22 and the starting moments of the different elevators in the elevator group 10.
Referring to fig. 3, in one embodiment, each of the elevators 11 further includes: an emergency processor 140.
The emergency processor 140 is configured to store and execute emergency handling modes, which include: it is detected whether the elevator 11 is a defective elevator.
And if the elevator 11 is a fault elevator, judging the position of the fault elevator. And if the fault elevator is on the flat floor, outputting a door opening instruction to the fault elevator. And if the fault elevator is in operation, controlling the nearest floor of the fault elevator to stop the elevator and outputting a door opening instruction. And if the fault elevator cannot run, continuously maintaining the current state.
In this embodiment, the execution process of the failed elevator is assumed and estimated in advance to a certain extent in consideration of different situations of each elevator 11 in the elevator group 10, so as to avoid the occurrence of the phenomenon that passengers are trapped in the failed elevator. In this embodiment, each of the elevators 11 may further include a voice broadcaster, configured to broadcast voice to passengers trapped in the car body 110 in an emergency, so as to reduce the stress and anxiety of the passengers in the car body 110 as much as possible. The specific voice broadcasting condition can refer to the voice broadcasting condition in the specific elevator group management operation mode, or be designed additionally according to actual needs.
Referring to fig. 4, in one embodiment, the elevator group management system 100 further includes a self-generating device 30.
The self-power generation device 30 is electrically connected to the group control cabinet 20 and the elevator group 10, respectively. The self-generating device 30 is used for sending electric energy to the group control cabinet 20 and the elevator group 10 when a power failure condition occurs in a power supply system of a building, a hotel or an office building.
In this embodiment, the group management cabinet 20 may monitor information on whether the self-generating device 30 is started or not in real time. The arrangement of the self-generating device 30 can prevent the embarrassment that the entire elevator group management system 100 cannot operate when power is cut off.
In one specific embodiment, referring to fig. 4 and 5, the elevator group 10 includes elevators one and elevators two … … N. When the group management cabinet 20 detects a self-power-generation signal of the elevator group 10, the processing operation of each elevator 11 in the elevator group 10 is: the first elevator returns to the refuge floor (one floor/reference floor) first, the duration of the return process (called the controlled running time) is limited, and the second elevator then returns to the refuge floor within a limited time regardless of whether the first elevator returns to the refuge floor or not. And the rest is repeated until the No. N elevators all return to the refuge layer. Wherein the return process duration for each elevator can be set to be different.

For the sake of convenience of distinction, the timer 120 of the first elevator is referred to as a first timer, the timer 120 of the second elevator is referred to as a second timer … …, and the timer 120 of the N elevator is referred to as an nth timer, and the current time of the first timer and the current time of the nth timer of the second timer … … are the same, so as to ensure the accuracy of timing. When the elevator detects a signal from the electricity generation, the first elevator returns to the refuge layer (one layer/reference layer) in advance, and the first timer starts to time. After the first timer reaches the control running time, whether the first elevator reaches the refuge floor or not is judged. The second elevator starts to return to the refuge floor, and the second timer starts to time. After the second timer reaches the control running time, whether the second elevator reaches the refuge floor or not is judged. And the next elevator starts to return to the refuge layer until the Nth timer of the No. N elevator counts time and reaches the control operation time.
According to the elevator group management method and the elevator group management system, after the elevator group 10 is judged to be in the self-generating state, the operation mode of the elevator group 10 can be switched to a specific elevator group management operation mode, so that the elevators in the elevator group 10 are started according to the preset control operation sequence of the elevators. After the elevator group 10 is judged to be in the self-generating state, the elevator group management method can still realize the control operation of the elevator group 10 even if information cannot be exchanged among the elevators. In the elevator group 10, in the specific elevator group management operation mode, the starting times of different elevators in the elevator group 10 are different, so that the elevator line load is not too large, and the dangerous situation of elevator operation is avoided.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
