Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The alarm method and system being operating abnormally the purpose of the present invention is to provide a kind of elevator, to solve existing elevator
The problem of maintenance can not find in time elevator faults and make related counter-measure to elevator faults to maintenance mechanism.
Realization of the invention is described in detail below in conjunction with specific attached drawing:
Embodiment 1:
Fig. 1 shows the flow chart for the alarm method that elevator provided in this embodiment is operating abnormally, for ease of description, only
Part related to the present embodiment is shown.
The alarm method that a kind of elevator is operating abnormally, the alarm method the following steps are included:
S110: the floor block information of elevator operation is obtained；
S120: acceleration rate threshold list corresponding with the floor block information is established；
S130: in the acceleration and acceleration rate threshold list judgement elevator operation exception according to elevator at runtime
When, it sends alarm signal and carries out elevator operation exception alarm.
In step s 110, floor block information is the track of elevator operation, including elevator is run from a beginning floor
The information of the purpose floor increased or decreased in the process of running to the information of multiple purpose floors, elevator, elevator were being run
The beginning floor information and new target floor information corresponding with the beginning floor information being newly added newly being added in journey.
For example, a beginning floor is " 1 building ", multiple purpose floors are " 2 buildings ", " 5 buildings ", " 8 buildings " and " 10 buildings ".When
Elevator after the new passenger that comes up and is arranged elevator and goes to " 13 buildings " in " 5 buildings " enablings, increases in the process of running for elevator for 13 buildings
The information of the purpose floor added.
One beginning floor is " 1 building ", and multiple purpose floors are " 2 buildings ", " 5 buildings ", " 8 buildings " and " 10 buildings ".Elevator exists
Operation is to when " 3 buildings ", and three buildings are not a floor in multiple purpose floors at this time, and therefore, " 3 buildings " are the starting building being newly added
Layer information.
In the step s 120, acceleration rate threshold list is corresponding with floor block information, including elevator is out of operation permission
Each beginning floor to all permissions in purpose floor acceleration rate threshold.It can also include: to obtain after step S120
The information for taking elevator increased new purpose floor in the process of running, according to the information of the new purpose floor to described plus
Threshold speed list is updated.
In the process of running due to elevator, by under multiple enabling visitor or it is upper visitor after, elevator operation beginning floor and
Purpose floor can all change.By establishing acceleration rate threshold list corresponding with floor block information, can be transported in elevator
State during row according to elevator operation is different, forms different judgment criterias, allows to carry out the alarm of elevator operation exception
Opportunity becomes more accurate.
In step s 130, acceleration includes the climb acceleration or vertical of the angular acceleration of horizontal direction, vertical direction
The decline acceleration in direction.Wherein, angular acceleration prolongs the degree of horizontal plane shaking for describing elevator in the process of running.Fig. 2
The specific flow chart of step S110 in the alarm method of the elevator operation exception of the offer of the embodiment of the present invention 1 is provided；
S111: first starting floor information and at least one purpose of the elevator in uplink or when downlink are obtained and stops floor
Information.
In step S111, the first starting floor information includes the letter of floor where elevator opens the door for the first time during uplink
Breath or elevator have executed floor information when equal machines are awaited orders after task.It includes elevator during uplink that purpose, which stops floor information,
One or more destination information in operation task are got after opening the door for the first time.
For example, elevator is in uplink, during rising to " 3 buildings " from " 1 building ", elevator opens the door for the first time in " 1 building ", at this time
First starting floor information be " 1 building ", purpose stop floor information be " 3 buildings ".For another example elevator is after rising to " 3 buildings "
Out of service, floor when equal machines are awaited orders at this time is " 3 buildings ", when elevator is activated again from " 3 buildings " and rises to " 5 buildings ", " 7
When building " and " 8 buildings ", the first starting floor information recorded at this time is " 3 buildings ", and it can be " 5 buildings " that purpose, which stops floor information,
" 5 buildings " and " 7 buildings ", or " 5 buildings ", " 7 buildings " and " 8 buildings ".
For another example elevator is in downlink, during dropping to " 3 buildings " from " 5 buildings ", elevator opens the door for the first time in " 5 buildings ", this
When first starting floor information be " 5 buildings ", purpose stop floor information be " 3 buildings ".For another example elevator is dropping to " 3 buildings "
Out of service afterwards, floor when equal machines are awaited orders at this time is " 3 buildings ", when elevator be activated and drop to again from " 3 buildings " " 2 buildings ",
When " 1 building " and " the 1 building ", the first starting floor information recorded at this time is " 3 buildings ", and it can be " 2 that purpose, which stops floor information,
Building ", " 2 buildings " and " 1 building ", or " 2 buildings ", " 1 building " and " the 1 building ".
In the present embodiment, elevator operation includes ascending for elevator and elevator downlink, by obtaining elevator in different operation shapes
Floor block information under state, the floor where elevator capable of being positioned when elevator is operating abnormally and alarms.Since elevator is being run
In the process, overweight or weightless phenomenon can be generated, therefore by obtaining floor of the elevator under the operating statuses such as upstream or downstream
Block information can not only distinguish the specific event of elevator operation exception, additionally it is possible to position floor zone where elevator is operating abnormally
Between information.
