Description
Technical Field
The invention relates to the field of elevators, in particular to an elevator emergency call system and method.
Background
At present, elevators are all provided with emergency call systems, so when abnormal conditions such as people being trapped occur in the elevator, the trapped people can establish calls with property, a remote monitoring center and the like by pressing emergency call buttons in a car, and accordingly, the trapped people can be pacified, assisted in rescue and the like. Remote monitoring centers are typically equipped with multiple service personnel for receiving emergency call requests from trapped persons within the elevator cars.
With the widespread use of elevators in modern society, for elevator companies whose products are sold to different countries and regions, the remote monitoring centers may receive emergency call requests from different countries and regions, which are in different languages. Even if emergency call requests are made from the same country and region, emergency call requests for passengers in an improper language may occur due to an increase in international traffic. Meanwhile, each service specialist in the remote monitoring center usually only masters one or more languages, and it is impossible to master all the languages, so that situations that the service specialist cannot successfully call because the language mastered by the service specialist is different from the language used by the passenger who makes the emergency call request, and the situation in the car cannot be confirmed, etc. occur.
In order to solve the above problems, chinese patent application CN201710482619.4 proposes an emergency call system for an elevator, which estimates the language of a passenger based on the building where the elevator is located or the telephone number of the call request, searches for and selects an operator corresponding to the estimated passenger language, and preferentially connects the line of the emergency call telephone to the telephone operated by the searched operator.
In the above prior art, a building or an elevator where the elevator is located is taken as a whole, and a speech language is set only according to the building or the elevator where the elevator is located or according to the difference of passengers in the building without considering the difference of floors or the difference of passengers in the building, and the speech language is fixed once set and does not change with the operation state of the elevator and the passengers inside the elevator. Since the building or the elevator where the elevator is located is taken as a whole when the call language is set, passengers in the elevator car cannot be distinguished, the system lacks necessary distinguishing capability, for example, for elevators in buildings with many foreign people and in cities with high internationalization degree, or passengers using different languages in the same building, the language used by the passenger may be estimated according to the building where the elevator is located or the telephone number initiating the emergency call request, so that the call language may be set by mistake in many occasions, and the estimation error rate is high, which is obvious in the above technical scheme. Obviously, there are two prerequisites for the implementation of this scheme: 1) it is assumed that passengers in the elevator car are limited to the proper owner of the building in which the elevator is located; 2) all owners in the building are only eligible for the same language. If the two preconditions are not satisfied simultaneously, the speech language determined by the scheme is likely to be wrong.
Therefore, how to ensure that the emergency call request initiated by the passenger can be quickly and accurately connected to the service specialist who can provide the same language for the passenger becomes a technical problem to be solved.

Detailed Description
Other advantages and effects of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown in the accompanying drawings, wherein the specific embodiments are by way of illustration. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced or applied in different embodiments, and the details may be based on different viewpoints and applications, and may be widely spread and replaced by those skilled in the art without departing from the spirit of the present invention.
To overcome the large limitations of the prior art, the most straightforward and accurate strategy should start with the inference process of refining the emergency call language, i.e. determining the emergency call language by identifying the identity information of the passenger in the car at the time the emergency call request was initiated. The implementation method can accurately determine the emergency call language, but in order to identify the identity of the passenger, additional identification devices, such as a camera (corresponding image identification algorithm is also needed), a card read by the passenger, a biometric identification device, and the like, need to be added, which leads to the disadvantages of complex system, high implementation cost, and the like.
In view of this, another refinement of the language determination basis is performed on the basis of the prior art: the whole building where the elevator is located is refined into each floor of the building, namely, the emergency call language is determined according to the floor where the elevator car is located when the emergency call request is initiated. This is the most conceivable solution in light of the prior art solution, but it still does not completely overcome the drawbacks of the prior art solution and is therefore not practical enough.
From the technical problem of how to determine the emergency call language of the passenger initiating the emergency call request, the emergency call language is inherently dependent on the passenger, and therefore the method of determining the emergency call language based on the passenger in the car at the time of initiating the emergency call request is necessarily the most accurate. However, considering various factors such as cost, the prior art scheme is feasible to estimate the language of the passenger by using the intermediate medium of the elevator building on the basis of two preconditions assumed to be satisfied (for the occasions such as a common residential building and a non-foreign business building), but is infeasible to determine the emergency call language according to the floor where the elevator car is located when the emergency call request is initiated (unless the elevator is also the common residential building or the non-foreign business building, that is, the language of the whole building is the same, but has no difference or improvement significance from the prior art scheme in this case), because the passenger does not have a definite relationship with the floor where the elevator car is located when the emergency call request is initiated (the floor where the elevator car is located when the emergency call request is initiated may correspond to any passenger, any language), the passenger in the elevator car cannot be identified by using the floor where the elevator car is located when the emergency call request is initiated as the intermediate medium, the emergency call language cannot be determined by means of the floor of the elevator car at the time the emergency call request was initiated.
As a first embodiment of the elevator emergency call system of the present invention, as shown in fig. 1, the elevator emergency call system includes:
the emergency call device is used for initiating an emergency call request to the remote monitoring center by passengers in the elevator car;
a first storage device for storing a floor-passenger language relationship table of a building in which an elevator is located;
the first processing device is used for estimating the floor of a passenger in the elevator car according to the floor stop information of the elevator when the emergency call request is sent, or the floor stop information and the passenger flow mode information, or the floor stop information and the passenger number information in the elevator car, and further estimating the emergency call language of the passenger in the elevator car according to the floor of the elevator and the floor-passenger language relation table in the first storage device;
a second storage means for storing a line-service language relation table indicating the types of the call lines and the service languages that the service specialist in charge of each call line can provide;
a line selection device for determining a call line in the remote monitoring center capable of providing an emergency call service of the emergency call language for passengers in the elevator car according to the emergency call language estimated by the first processing device and the line-service language relationship table in the second storage device, and outputting the call line as a selected call line;
a line control device that connects a line of an emergency call initiated by a passenger in an elevator car to the selected call line output by the line selection device.
An elevator emergency call method implemented based on the elevator emergency call system of the embodiment, as shown in fig. 2, includes the following steps:
step S1, the passenger in the elevator car sends an emergency call request to the remote monitoring center;
step S2, estimating the floor of the passenger in the elevator car according to the floor stop information of the elevator when the emergency call request is sent, or the floor stop information and the passenger flow mode information, or the floor stop information and the passenger number information in the elevator car, and further estimating the emergency call language of the passenger in the elevator car according to the floor of the elevator and the floor-passenger language relation table;
step S3, determining a call line capable of providing emergency call service of the selected call language for passengers in the elevator car in the remote monitoring center according to the emergency call language and a line-service language relation table, and outputting the call line as the selected call line, wherein the line-service language relation table is used for representing the corresponding relation between the call line and the type of service language capable of being provided by a service specialist in charge of each call line;
and step S4, connecting the line of the emergency call initiated by the passenger in the elevator car to the selected call line, and enabling the passenger in the elevator car to establish the emergency call with the service specialist corresponding to the selected call line.
Wherein, the floor-passenger language relation table comprises each floor of the building where the elevator is positioned and at least one optional language of each floor owner corresponding to the floor. When the number of the selectable languages corresponding to a certain floor is larger than 1, the floor-passenger language relation table also comprises weight coefficients corresponding to different selectable languages of the certain floor. The weighting coefficients corresponding to different selectable languages depend on the number of owners in the floor who have each selectable language as the main language.
In step S2, when the emergency speech language estimated by the first processing device includes a plurality of selectable languages, a selectable language with the largest weight coefficient is selected from the selectable languages as the emergency speech language estimated by the first processing device.
The following further explains a specific case where the first processing device estimates the emergency speech of the passenger in the elevator car.
In a first case, in step S2, the first processing device estimates the emergency call language from the floor stop information of the elevator at the time of the emergency call request, in which case the floor stop information includes the stopped floor and/or the destination floor at which the elevator car is to stop in the current direction of travel, and estimates all selectable languages corresponding to the stopped floor and/or the destination floor at which the elevator car is to stop as the emergency call language from the floor-passenger language relationship table.
In a second case, in step S2, the first processing device estimates the emergency call language according to floor stop information and passenger flow mode information of the elevator when the emergency call request is issued, where the floor stop information includes a stopped floor and/or a destination floor to be stopped of the elevator car in the current running direction, and the passenger flow mode information refers to a passenger flow mode of the elevator when the emergency call request is initiated, and includes divergent passenger flow, convergent passenger flow, and regular passenger flow. In this case, the emergency call language is estimated as follows:
if the passenger flow mode information is divergent passenger flow, for example, passengers go to each floor in a building from a main floor station (a first floor of a hall) in the early peak, the first processing device presumes the emergency call language according to the destination floor at which the elevator car is about to stop in the current running direction and the floor-passenger language relation table;
if the passenger flow mode information is convergent passenger flow, for example, passengers go to a main landing (first floor of a hall) from each floor in a building at night peak, the first processing device presumes the emergency call language according to the stopped floor and/or the current stopping floor (in the case that the elevator car is in the stopped state) of the elevator car in the current running direction and the floor-passenger language relation table;
if the passenger flow mode information is normal passenger flow, the first processing device estimates the emergency call language according to the stopped floor and/or the destination floor to be stopped of the elevator car in the current running direction and the floor-passenger language relation table.
In a third case, in step S2, the first processing device estimates the emergency call language according to the floor stop information of the elevator and the information about the number of passengers in the car when the emergency call request is issued, where the floor stop information includes the stopped floor and/or the destination floor of the elevator car in the current running direction, and if the passenger in the elevator car takes the elevator alone all the way when the emergency call request is issued, the first processing device estimates the emergency call language according to the departure floor or the destination floor of the passenger and the floor-passenger language relationship table, and specifically includes the following steps:
step S21, judging whether the passengers in the elevator car are taking the elevator independently in the whole journey when the emergency call request is initiated, if so, entering step S22, otherwise, entering step S23;
step S22, presume the said urgent speech according to the said passenger' S departure floor and destination floor and said floor-passenger language relation table of the elevator cab, finish;
step S23, judging whether the passenger in the elevator car is one of the passengers getting on the elevator at the same time and the rest passengers getting on the elevator have been off the way (identified by the camera or the weighing device of the elevator, for example, the weighing result of the weighing device continuously and steadily decreases), if yes, estimating the emergency call language according to the floor corresponding to the maximum weighing value of the weighing device or the floor corresponding to the maximum weighing value and the stopped floor before the floor of the elevator car in the current running direction by combining the floor-passenger language relation table, and ending; and otherwise, estimating the emergency call language of the passenger in the elevator car according to the stopped floor and/or the destination floor to be stopped of the elevator car in the current running direction and the floor-passenger language relation table, and ending.
Further, in step S22, the emergency speech may also be estimated in conjunction with the direction of travel of the elevator car, specifically:
when the elevator car runs in a direction far away from the main landing, the first processing device estimates the emergency call language according to the target floor at which the elevator car is about to stop in the current running direction and the floor-passenger language relation table;
when the elevator car is driven to the main landing, the first processing device estimates the emergency call language according to the departure floor of the passenger entering the elevator car and the floor-passenger language relationship table.
In step S21, in a first mode, when the elevator is in a standby state before the passenger enters the elevator car and the elevator car does not make an intermediate stop in the process from the starting operation of the elevator to the issuing of the emergency call request, the first processing device judges that the passenger takes the elevator alone in the whole process;
in the second mode, when the weighing result of the elevator weighing device does not exceed the set weight (for example, the set weight is the weight of one passenger) and the elevator car does not stop halfway from the starting operation of the elevator to the sending of the emergency call request, the first processing device judges that the passenger rides the elevator independently in the whole process.
In a fourth case, in step S2, the first processing device estimates the emergency call language according to the floor stop information of the elevator at the time of the emergency call request and the current operation condition of the elevator, where the floor stop information includes a hall call floor at which the elevator is already stopped, a destination floor (registered in the car) at which the elevator is already stopped, and a destination floor at which the elevator is to be stopped. In the current running direction, after the elevator stops in the middle due to landing calling, the specific conditions include:
the situation A is that if a passenger entering the elevator car later arrives at a destination floor earlier than an original passenger in the elevator car (for example, in the process of ascending the elevator car, the destination floor of the passenger entering the elevator car is 5 floors, the destination floor of the original passenger in the elevator car is 10 floors, or in the process of descending the elevator car, the destination floor of the passenger entering the elevator car is 5 floors, the destination floor of the original passenger in the elevator car is 1 floor, and the passenger leaving the elevator car enters the destination floor of the passenger in the elevator car before sending the emergency call request, at this moment, the passenger entering the elevator car leaves the elevator car at a high probability, only the original passenger not arriving at the destination floor is left in the elevator car, the emergency call is initiated by the original passenger in the elevator car, therefore, the first processing device only needs to call the landing calling floor (namely, the starting floor) of the original passenger in the elevator car, the destination floor to be stopped and the language relationship between the passenger and the passenger The table may be used to estimate the emergency call language without estimating from all of the stop floors.
And in case B, if the passenger entering the elevator car later arrives at the destination floor earlier than the original passenger in the elevator car and the elevator car sends the emergency call request before arriving at the destination floor of the passenger entering the elevator car later, the passenger entering the elevator car later and the original passenger in the elevator car later do not leave the elevator car, the emergency call can be initiated by the passenger entering the elevator car later and can also be initiated by the original passenger in the elevator car, and therefore the first processing device needs to estimate the emergency call language according to the calling floors of all passengers in the elevator car at the landing, the destination floor to be stopped and the floor-passenger language relation table.
In case C, if a passenger entering the elevator car later than an original passenger in the elevator car arrives at a target floor of the original passenger in the elevator car and the elevator car leaves the target floor of the original passenger in the elevator car, the emergency call request is sent, at the moment, the original passenger in the elevator car leaves the elevator car, the passenger only leaves the elevator car and enters the elevator car after the passenger leaves the elevator car, and the emergency call is initiated by the passenger entering the elevator car from the rear, so that the first processing device only needs to estimate the emergency call language according to a landing call floor of the passenger entering the elevator car from the rear and the target floor to be stopped;
and in the case D, if the passenger entering the elevator car later than the original passenger in the elevator car arrives at the destination floor of the passenger, and the emergency call request is sent before the elevator car arrives at the destination floor of the original passenger in the elevator car, the first processing device presumes the emergency call language according to the landing calling floors of all passengers in the elevator car and the destination floor to be stopped, which is the same as the case B.
In the elevator emergency call system and method of the embodiment, assuming that the emergency call language of the passenger on each floor of the building where the elevator is located is known, the relationship between the floor and the passenger language is determined, and on the basis, which floor the passenger belongs to can be estimated according to the floor stop information, the passenger flow mode information, the passenger quantity information and the like of the elevator car, so that the passenger can be identified by means of the floor corresponding to the passenger, and the estimation of the emergency call language is realized.
