Description

Elevator information display system

Technical Field

The present invention relates to an elevator information display system, and more particularly, to an elevator information display system for easily explaining to a manager an operation-hindering factor caused by concentration of use guests or the like.

Background

In an office building and an apartment building, the number of users of an elevator is predicted at the time of building planning, and smooth operation is enabled by setting the number of elevators, the speed, the capacity, and the like to optimum specifications. However, since the prediction of the number of people used also varies depending on the use of the building and the number of floors, the elevator operation state after installation may differ from the prediction at the time of building planning.

Therefore, after installation, a building management company or a maintenance company that performs maintenance of the elevator monitors the operation state, performs data analysis based on the operation information of the elevator, and performs control of operation of a plurality of elevators, setting change of a departure reference floor, and the like, so that optimum operation can be performed with a small waiting time of each floor.

As an invention related to these, patent document 1 proposes an elevator operation state monitoring system including: the operation state of the elevator is monitored, information is notified to a manager or a tenant of the building as necessary, and the operation information at that time is recorded.

Further, patent document 2 proposes an elevator operation monitoring system having the following functions: the information of the activities of the building is registered in a building management system, and the contents of the activities and the date and time are displayed on a display of a destination floor registration device and a personal information portable terminal provided in an elevator so that a user can grasp the contents and perform a priority operation when a specific condition is satisfied.

Problems to be solved by the invention

However, in the system of the patent document 1 in which the operation state is displayed in real time by a monitor for monitoring the operation state of the elevator and recording the operation information in order to monitor the operation state of the elevator by a building management company or a building owner, it is difficult to quickly grasp the cause of the current elevator congestion and the cause of the past elevator congestion occurring at a specific date and time, and it is necessary to separately request an investigation to an elevator maintenance company, collect operation data for a certain period of time, and analyze the data based on the collected data.

In the elevator apparatus described in patent document 2, there is no consideration given to an application or the like in which, when an event or the like is planned at a specific floor of a building, a manager of the building changes the setting so that the operation control of the elevator becomes an optimum state, so that congestion can be avoided in advance. Further, there is a problem to be solved before technical measures such as such a change in setting.

For example, when a guest partially concentrates on an elevator due to any reason and the elevator is congested, it is frequently suspected whether the elevator is faulty or not. The reasons for this are sometimes inequalities such as entertainment in the area, climate, or disorder of the vehicle. In the case where the cause of the elevator congestion or the like currently occurring as described above is not the elevator itself, the best countermeasure against the problem is to explain the cause to the manager with ease of understanding, and often no special technical support is required.

More specifically, in a general commercial building, when a congestion state of 5 minutes or more is continued for 1 hour or more even when a guest calls an elevator and the car arrives, a complaint is often made to a building manager, and therefore appropriate complaint processing is required. Complaint handling is required to be promptly coped with without deterioration of the situation. Here, if the cause of the elevator congestion is definitely an ineligible force that can be objectively described, it is not possible for a technician in the elevator maintenance professional to deal with the complaint. In this case, it is sufficient that a person who is generally familiar with interpersonal countermeasures (hereinafter, also referred to as a "non-skilled person") explains the cause of the congestion.

Even if the above-mentioned "technical person" and "non-technical person" are compared only in number, the "technical person" is of course rare. Furthermore, when a technician is dispatched to the site to perform a corresponding technical response, labor cost and other costs are not reduced. Further, although there is no need for a technical task of collecting operation data for a certain period of time by a technician and analyzing the data, it is desirable to save labor and cost of a rare technician. In contrast, if there is a tool that functions as an explanation assistance method for appropriately performing complaint handling by a non-skilled person or for quickly and easily explaining to a person who has proposed a complaint that current congestion or the like is an ineligible force and its cause and effect, it can be expected that a better result will be produced.

Disclosure of Invention

The present invention is intended to solve such problems, and has an object to: provided is an elevator information display system which can easily eliminate suspicion by displaying an operation hindering factor that hinders operation of an elevator by concentrating use guests to a manager when the elevator is suspected to be faulty although the elevator is not faulty or is expected to be suspected to be faulty.

Solution scheme

In order to solve the above problems, the present invention is an elevator information display system for displaying information related to the operation state of an elevator on a terminal, comprising: a related information storage unit for storing related information which is information on an inhibitor that may inhibit the operation of the elevator; and a screen generating part for displaying an elevator congestion degree screen on the terminal, wherein the elevator congestion degree screen comprises time sequence information representing the elevator congestion degree in time sequence and information which is determined according to the related information and represents the obstruction factor related to the corresponding position of the time sequence information in a visual confirmation mode.

Effects of the invention

According to the present invention, a building management company, a terminal which a business owner of a building can read, confirms the operation condition of an elevator, and displays the activities related to the building, the adjacent activity information, the surrounding traffic information, the weather information, the earthquake information, the maintenance work information of the elevator, and the like in combination, thereby making it possible to grasp not only the current but also the cause of the specified date and time from the past to the near future with respect to the congestion condition of the elevator.

Therefore, it is possible to provide an elevator information display system that, when a failure is suspected although the elevator has no failure or when such a suspicion is expected, displays an operation inhibiting factor such as a use guest group to a manager, thereby easily eliminating the suspicion.

Detailed Description

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Note that, although not particularly shown in the drawings, the basic configuration of the computer device is composed of a communication unit, an input/output unit, an arithmetic processing unit (hereinafter also referred to as "CPU"), a storage unit, and a program. In addition to a database (hereinafter, simply referred to as "information") for storing various information distinguished according to purposes, which is formed in each storage area of the storage unit, the computer device also forms each function illustrated below by executing a program stored in the storage unit by the CPU. The information processed here is accumulated in a database and then read out.

Fig. 1 is a block diagram showing the structure of a data center of the present system. As shown in fig. 1, the system is composed of a data center, a group management elevator 19, and a customer terminal 2. The data center forms the core of the system and is a computer device that performs operation control, operation management, or operation support for the group management elevators 19. Furthermore, the invention is not suitable for singles, but for use in group management elevators 19.

The data center is composed of a computer system, and the computer system is composed of more than one computer. Each computer of the configuration of the example elevator information display system (the present system) has a plurality of computer resources such as an interface device, a storage device (e.g., a main storage device, an auxiliary storage device), and a processor connected thereto. Based on a plurality of computer resources provided in the data center, functions such as communication with external devices such as the customer terminal 2 and the group management elevator 19, storage of information such as the building master information 19 described later using fig. 1, and the server processing unit 3 are realized.

The customer 1 described here is not a guest of use of an elevator, but represents a manager of an elevator or an owner of a building, and may be referred to as a manager 1 instead. The client terminal 2 is preferably a tablet terminal or a personal computer (hereinafter referred to as "personal computer" or "PC") for connecting information to a data center so that the client 1 can view information desired to be known. The customer terminal 2 forms an input/output unit to the data center, and when the customer 1 is an elevator manager, it can perform operations such as setting changes in the operation control of the group management elevator 19. The client terminal 2 of the present embodiment corresponds to the terminal of the present invention.

The information that the customer desires to know is related information represented by the degree of congestion of the elevator. More specifically, the information corresponds to external information such as traffic congestion of an elevator, activity information related to the building, traffic information of a neighboring public transportation, and weather information. These pieces of information are information that, in the case where the customer 1 is the manager of the elevator, play a role in eliminating the question of "whether or not the elevator is congested due to a failure". That is, the information is used to objectively explain the factor of the hindrance to the occurrence of the force of ineffectiveness to the operation of the elevator in the environment where the elevator is installed.

The blocking factor is a factor that may affect the degree of congestion of the elevator. Furthermore, the hindering factor handled in the present system is not only a really possible hindering factor but may even include a factor that is not even known as whether or not the fact is a hindering factor. In addition, the hindering factor is not limited to only information obtained by actively collecting. For example, in a theater, even when a user is on the scene or is on the backdrop, the user can visually confirm the cause of congestion of an elevator installed therein without collecting information. In this case, an obstruction factor to the operation of the elevator is also generated.

The data center is composed of a server processing unit 3, an operation control setting unit 6, an operation data collection device 7, elevator operation information (description of "database" is omitted) 8, a related information storage unit 9, building master information 16, and an external information collection device 17. The elevator congestion degree screen generation unit 4 generates screen data to be displayed on the customer terminal 2. The information search unit 5 appropriately searches and provides the required elevator running information 8 and various information stored in the related information storage unit 9. The server processing unit 3 and the elevator congestion degree screen generation unit 4 according to the present embodiment include the screen generation unit according to the present invention.

The operation data collecting device 7 periodically collects elevator operation information 22 from the group management elevators 19. The elevator operation information 8 is stored in the database with the operation data of the elevator periodically collected by the operation data collection device. The related information storage unit 9 includes a database having 6 storage areas, and is configured from hall meeting room reservation information 10 of the building, activity data 11 of the building, weather and earthquake information 12, traffic information 13, neighborhood facility use information 14, and elevator maintenance information 15. The elevator maintenance information 15 is information on the sequence of equipment maintenance, repair, etc. of the elevator and building.

The elevator congestion degree screen generation unit 4 performs information processing related to screen generation and display as follows. The congestion degrees of the elevators are collected from the group management elevator 19. Information indicating the timing and the degree of congestion of at least one of the group control elevators 19 is accumulated.

The relation information storage unit 9 shows the relation between the interference factor and the time range. The blocking factor is associated with a time range that matches the time range indicated by the blocking factor in the time-series congestion degree table (see fig. 3 and 5) so as to be visually recognizable. The congestion degree can be determined based on, for example, the ratio of the actual number of passengers (or the actual weight) to the number of people that can be carried by the car (or the weight that can be carried), but operation data such as the hall call count of each hall of the elevator, the waiting time of the passengers, and the like may be added to the calculation of the congestion degree. The number of passengers, the weight can be determined from sensors (e.g. cameras, weight sensors) provided in the elevator.

The blocking factor displayed on the customer terminal 2 in a visually recognizable manner by the elevator congestion degree screen generating section 4 is extracted based on the priority of the blocking factor. The priority of the blocking factor is determined according to the frequency of the operation history of the customer 1. For example, a plurality of screen contents indicating the blocking factors are associated with the operation history of the customer 1 viewing them, and search IDs not shown are given in order of high operation frequency, thereby forming a database in the associated information storage unit 9. That is, the higher the frequency of registration as the operation history of the customer 1, the higher the priority of registration as the blocking factor.

Based on the database and the registration contents, the customer 1 semi-automatically knows what blocking factors have been selected from the screen of the customer terminal 2 in the past and views the relationship between the operation history related to the detailed contents and the features related to the time-series congestion degree of the elevator. Thus, it is possible to know how frequently to select the blocking factor even in the case of the time-series congestion degree having what characteristic. In other words, it is shown that the customer 1 estimates the difference in the influence on the degree of congestion with a certain degree of certainty from the characteristics of the time-series degree of congestion.

Fig. 2 is a block diagram showing the structure of a group management elevator 19 supported by the present system of fig. 1. As shown in fig. 1, the group management elevator 19 is composed of a plurality of elevators (hereinafter also referred to as "elevator groups") 23a to 23n, a group management control device 21, elevator operation information 22, and a communication device 20.

The group management control device 21 controls the operation of the elevator groups 23a to 23n based on the elevator group management. Elevator group management is known to be roughly divided into the following 2 types: allocation control for allocating an optimal elevator in accordance with a traffic condition in a building; the operation control of the operation of the elevator groups 23a to 23n is determined in accordance with a large change in traffic flow which periodically repeats such as at work and lunch.

The elevator operation information 22 stores and temporarily stores operation data of the elevator groups 23a to 23n in a storage medium such as a memory card provided in the group management control device 21. The communication device 20 can perform bidirectional communication with the data center via a communication network not shown. If the direction to the data center is the upward direction, accumulation is performed so that the elevator operation information 22 is uploaded to the data center. Conversely, operation information such as a change in the setting of the customer 1 using the customer terminal 2 is transmitted from the operation control setting unit 6 of the data center to the group management elevator 19 in the downward direction.

Next, a procedure in which a customer 1 such as a building owner or a management company confirms an operation state of an elevator and grasps a cause of congestion by using a nearest customer terminal 2 connected to the system will be described with reference to the drawings. The group management elevator 19 is controlled so that the plurality of elevators 23a and 23b … … 23n operate optimally in response to the car call and the hall call.

However, when a business is held in a building, there are cases where a queue of waiting participants in the elevator hall is generated for the elevator to go to the floor where the business is located, and an elevator jam occurs in which the elevator car is full of passengers and cannot be loaded even if a hall call is made. In this respect, there is a need for improvement in the sense of dissatisfaction from the users of elevators, tenants.

In such a case, the management is conventionally handled by a building owner or a building management company (manager). That is, the manager checks the cause of the congestion and requests the technicians of the elevator maintenance company to investigate the operation state of the group management elevator 19 according to the contents to improve the operation. The technician acquires the operation data of the elevator for a certain period of time, and changes the setting related to the operation control of the group management control device 21 to the optimum setting based on the analysis result.

Next, an embodiment of the present invention is shown. First, the elevator operation information in the group management elevator 19 shown in fig. 1 is transmitted from the operation data collection device 7 to the communication device 20 of the group management elevator shown in fig. 2, and the elevator operation information 22 stored in the storage device such as a memory card provided in the group management control device is periodically collected and stored in the elevator operation information 8 shown in fig. 1.

Fig. 3 is a diagram of a representative screen displayed to a customer terminal by the present system of fig. 1. The screen shown in fig. 3 is a screen on which the customer 1 creates a histogram of the congestion level transition chart of the elevator and the information on the reservations of the event hall and the conference room from the own customer terminal 2 such as a personal computer and a tablet computer and displays them in a vertical arrangement in order to investigate the cause of congestion. The time sequences are displayed in a consistent and easily intuitive manner.

The customer 1 specifies the date (year, month, day) of congestion using the customer terminal 2. The data center having received this operation generates a congestion degree transition of the elevator based on the elevator operation information 8 for a specified amount of one day by the elevator congestion degree screen generating section 5, and displays the generated congestion degree transition on the upper part of the screen in fig. 3. For example, in the case of the screen illustrated in fig. 3, it can be grasped that congestion different from that in normal times occurs in 2 time slots 31 of 16 to 20 points.

In the lower part of the screen, the time zone of the date of the congestion is used as a search condition, and the information search unit 5 searches each data accumulated in the related information storage unit 9 from the user performance data of the elevator operation information 8, and extracts and displays the corresponding congestion cause data. From the screen illustrated in fig. 3, it can be understood that the activities performed in the halls a to C and the activities performed in the meeting room D have been repeated at 16 to 20 points in the elevator congestion degree transition chart.

This makes it possible to determine that the number of passengers who use the elevator increases and a congestion occurs in the time zone. That is, it is possible to clearly, objectively and instantaneously explain that the cause of congestion is not a failure of an elevator, and it is a natural phenomenon that occurs to a manager although it is not absolutely indispensable.

Fig. 4 is a view of the screen displaying various information replaced as appropriate in the lower part of the screen of fig. 3. As shown in fig. 4, the traffic congestion degree transition chart of the elevator is retained in the upper part of fig. 3, the information of the reservation in the lower active hall and the conference room is created as a histogram, and the chart shows the delay of the electric train when the traffic information is changed and displayed.

At this time, the customer 1 selects a time slot displayed on the lower part of the screen of the customer terminal 2 from the screen by a cursor or the like. From this screen, it is possible to grasp the cause of congestion in a time zone 32 of 9 to 11 points in which the degree of congestion of the elevator in fig. 3 has progressed, in which case the electric train of 2 routes of the adjacent public transportation means is delayed, and in this case, the congestion is caused in a time zone different from the normal time.

That is, it can be clearly and objectively described at a glance that the cause of congestion is not a failure of an elevator but is indispensable to a manager. By displaying weather and earthquake information, traffic information of neighboring vehicles, operation information of the building, and the like on the same day as the transition of the congestion degree of the elevator on one day in a vertically aligned manner on the screen of the client terminal 2, the cause of the congestion can be grasped in different time slots.

Fig. 5 is a diagram of a screen obtained by replacing the lower part of the screen in which fig. 3 and 4 are integrated. That is, the display example of fig. 5 is displayed in a tabular form summarizing the reasons for displaying on the lower part of the screen. Fig. 6 is a diagram showing a screen on which detailed information prepared by appropriately shifting the lower part of the screen in fig. 5 can be displayed. Time slots nos. 1 to 4 shown in the congestion degree transition chart of the elevator shown in the upper part of the screen of fig. 5 correspond to item nos in the left column of the table in the lower part of the drawing.

Further, by selecting the detail key 51 in the right column of the table in the lower part of the screen in fig. 5, the detailed contents can be displayed in a switched manner and confirmed. That is, the tables shown in fig. 6 as being differentiated into 3 types can be confirmed sequentially from the upper side of fig. 6 while appropriately switching 3 types of detailed contents, such as the conference room/event hall reservation status, the public transportation vehicle traffic information, and the elevator maintenance work information.

Fig. 7 is a flowchart showing an elevator environment display method (hereinafter also referred to as "the present method") according to an embodiment of the present invention. If the description contents of fig. 7 are explained briefly, the method includes a congestion determination step S1, a current and past determination step S2, an operation stop cause determination step S3, a real-time operation condition confirmation step S4, a detailed content confirmation step S5, a confusion avoidance step S6, a cause confirmation step S7, a simulation step S8, a simulation suitability confirmation step S9, a prior avoidance step S10, and a disaster response step S11.

The present invention is applied to a case where a customer 1 such as a building management company or a building owner deals with an elevator congestion using the present invention. Since the customer 1 grasps the operation state when the elevator is congested, it is possible to register a graph of the average congestion degree of the building in a normal state in the function of the elevator congestion degree transition graph in fig. 3 in advance, so that it is possible to determine that congestion different from the normal state has occurred, based on the difference in the display of the elevator congestion degree transition graph.

In the congestion determination step S1, when it is determined that the traffic congestion is different from the predetermined normal time by referring to the result of the threshold value set for each time point, although the traffic congestion is not abnormal due to a fault, the process proceeds to step S2 in which the current traffic congestion and the past traffic congestion are specified and displayed. In step S2, it is desired to grasp the cause of the current congestion of the elevator in the building to be classified or the cause of the congestion occurred in the past.

If it is determined in step S2 that congestion occurred in the past, the routine proceeds to operation stop cause determination step S3. If it is determined in step S2 that the current congestion state is present and the cause thereof needs to be grasped, the process proceeds to step S4, where the real-time operation status is confirmed.

In step S4, when dealing with the elevator traffic jam that is currently occurring, it is necessary to acquire the operation data in real time, and the operation data up to the present day and the latest operation data stored in the elevator operation information 22 of fig. 2 are read from the operation data collection device 7 of fig. 1 at intervals of several seconds and stored in the elevator operation information 8, thereby making it possible to confirm the current elevator operation status.

Next, in the detail confirmation step S5, the building user visualization screen different from the present invention confirms the detailed information such as the number of waiting persons in the lobby different from the floor of the elevator user. Next, in the confusion avoiding step S6, according to the congestion situation, it is possible to perform a countermeasure such as restricting entry into the building and guiding by arranging a security guard. Reaching the step S6 is a result of performing the method.

On the other hand, if yes in the operation stop cause determination step S3, the process proceeds to a disaster countermeasure step S11. Reaching this step S11 is also a result of performing the method.

In the cause confirmation step S7, the customer 1 confirms the cause by visually confirming the screens of fig. 3 and 4. In the simulation step S8, in order to cope with congestion of the same size that will occur in the future, an index relating to the car waiting of the elevator user is calculated and set to an optimum value by applying a simulation of the operation of the group management elevators or the like proposed in the above-mentioned patent document 2 (japanese patent application laid-open No. 2017-178589).

Next, in the simulation suitability confirmation step S9, it is confirmed whether or not the congestion of the same size as described above is alleviated to the allowable limit or less. Here, if it is confirmed that the simulation result is appropriate (yes in S9), the process proceeds to the advance avoidance step S10, and advance measures such as congestion avoidance can be taken. On the contrary, if the result of the simulation is confirmed to be inappropriate (no in S9), the process returns to the simulation step S8, and an optimum setting is sought.

According to the method, as shown in steps S1 to S3 and S7 to S10, if the customer 1 viewing the customer terminal 2 perceives a slight change from the display screen and is expected to have a congestion or the like (S1), and a setting change for avoiding such a change (yes in S9) can be made, it is possible to deal with the situation effectively in advance (S10).

That is, when a congestion under the same condition is expected during the actual operation of the elevator with reference to the past example (S7), the set value related to the operation control calculated (S8) by the operation simulation can be used. That is, the customer 1 can perform a countermeasure such as avoiding congestion in advance by remotely operating the operation control setting unit 6 (fig. 1) using the customer terminal 2 and changing the setting value.

The case where a congestion is expected in step S7 corresponds to "a case where a failure is suspected although the elevator has not failed, or a case where such a suspicion is expected" which is the subject of the present invention. In this case, the above-mentioned doubt can be eliminated by omitting steps S8 and S9 relating to the simulation and displaying only the elevator information by the present system to clearly display the congestion cause.

In addition, the system can perform cooperative application while sharing information with other systems. For example, in an existing maintenance system, an elevator maintenance company establishes a communication method for coping with a closed accident caused by an earthquake or a power failure. Disaster information can also be obtained from a monitoring device managed in such an existing maintenance system.

Therefore, if there is a failure such as a closure or a stop of operation, or a natural disaster accident such as an earthquake (S3), it is possible to more accurately provide the customer 1 with useful elevator restoration support information by combining disaster information from the existing maintenance system, earthquake information acquired by the system itself from the external information 18, and the like (S11).

Finally, the meaning of the invention is explained from other points of view. For example, in a conspicuous place of a user manual of a home appliance, "before calling a service person for a failure, the user tries to check the following items". This is to encourage the user to agree not to be a failure if the condition is reviewed objectively and quietly according to the recommended examination items even if the user thinks it is a failure. This has the effect of paying commissions and the like to the service staff without waste. Similar effects can be obtained in the present invention.
