Description

Description: TECHNICAL FIELD The present invention relates to a display device for displaying operating information of an elevator at a hall (hall), and in particular, relatively,
The present invention relates to a hall display device suitable for an elevator that has many general passengers from the outside.

[Conventional technology]

The presence of waiting time is unavoidable on average in the use of elevators, so it is essential to install a hall display device. Passengers who encounter this waiting time generally have to pay attention to the hall display device.

Therefore, by utilizing the customer's attention to the hall display device during this waiting time, in addition to simply displaying the elevator operation information, various event information and weather forecasts in the building in which this elevator is installed Various techniques for displaying general information have been proposed, examples of which can be found in JP-A-60-191977 and JP-A-61-136887. As an example, disclosed is such that the length from the start to the end of display is such that the optimum message is selected according to the length of the waiting time, or the optimum speed of the scroll display is selected. Has been done.

On the other hand, as a related matter, in Japanese Patent Laid-Open No. 61-226479, general information having different message contents is sequentially displayed in the car depending on the floor on which it arrives. The disclosed technology is disclosed.

However, what can be said in common with these conventional technologies is that the emphasis is placed on displaying general information rather than elevator operating information. This is suitable when the display is independently performed and different display devices are provided.

[Problems to be solved by the invention]

The above-mentioned conventional technology does not consider the common display of the general information and the elevator operation information by the hall display device, and has a problem in that the elevator operation information is accurately provided to the special customer. .

In addition, there is a problem that the cost accompanying the installation of a plurality of display devices is increased and the usability of the waiting customers is deteriorated because the plurality of display devices must be focused.

An object of the present invention is to provide a hall display device for an elevator, which is capable of always displaying the elevator operation information and general information appropriately and without increasing the cost and deteriorating the usability of waiting passengers.

[Means for solving problems]

The above-mentioned purpose is to display the elevator operation information and general information alternately on the hall display device, and under the predetermined condition set in advance, the display of the elevator operation information has priority over the display of general information. Is achieved as it is done.

[Action]

As a result of the elevator operation information and general information number being displayed alternately on the hall display device at one location, waiting passengers do not need to pay attention to multiple display devices, and the information necessary for grasping the elevator operation status Since the display is preferentially obtained, the elevator operation information can always be accurately known.

〔Example〕

Hereinafter, a hall display device for an elevator according to the present invention will be described in detail with reference to the illustrated embodiments.

First, the display operation in one embodiment of the present invention will be described with reference to FIG. 1, which shows a hall display device in a hall on the third floor when the present invention is applied to an elevator serving the fourth floor. As shown in FIG. 9A, the weather forecast of a plurality of messages is displayed as general information. Note that this general information is not limited to the weather forecast shown in the figure, but in addition to this, the current time, entertainment on the floor at the department store, guidance on the sales floor, train departure time at the station building, etc. can be considered. Are not directly related to the elevator operation information.

Next, in the same figure (b), the operating condition of the elevator becomes a predetermined state, for example, the state immediately before the car reaches this floor, the display of general information is interrupted, and then It shows the time when switching to the display mode of the elevator operation information. Various information can be considered as the elevator operation information at this time,
In this embodiment, it is as shown in FIG.

That is, i) the position of the car currently running (square mark) ii) the driving direction of the car currently running (upward or downward triangular mark) iii) floor to be stopped due to car or hall call ( Circle mark) iv) Floor mark on the floor (floor number is highlighted by lighting inside circle) v) Number of passengers in the car (puppet mark is partially lit).

By the way, the display of the operating information of the elevator changes depending on the operating condition thereof, as shown in FIGS. 2 (b) and 2 (c).

First, in the same figure (b), the stop call on the second floor is serviced,
This is an example of the display when the number of people in the car is 50%, and the figure shows the state where the car has reached the calling floor on the 3rd floor and the door is open. It is a thing.

By the way, as the predetermined condition for switching from the above general information to the display of the elevator operation information, various conditions can be considered, but in this embodiment, the following conditions are satisfied. That is, In addition to this, conditions such as when a waiting passenger is detected by the waiting passenger sensor may be considered.

Next, referring to FIG. 3, in a display example in which the present invention is applied to an elevator system in which a plurality of elevators are controlled, three units (#A, #B, #
It is a display example by the hall display device of the elevator in C), where each of the units #A and #C is displaying general information, and the unit #B is displaying the operating information of the elevator, that is, only the assigned elevator. It is the example which is displaying the driving information of an elevator. At this time,
It is needless to say that the general information other than the assigned elevator may be different messages or the same general information as shown in FIG.

By the way, various system configurations for embodying the present invention are conceivable. First, FIG. 4 shows general information including a message transmitting device MESG, a number control device, a local area network LANc, and a hall controller HC ₁ . The hall controller HC ₁ is arranged on each floor and is connected to the local area network LANc in one embodiment in which the hall display device DISPLAY is used for display. The embodiment shown in FIG. 4 shows the case of an elevator system on the fourth floor, and a hall call HALL is connected to the hall controller HC ₁ .

The feature of the embodiment shown in FIG. 4 is that the local area network LANc has one line and a hall controller is provided for each floor, which results in a simple system configuration.

Next, FIG. 5 shows another embodiment of the present invention in which the information transmission system is divided into two systems and the local networks are LANc and LANi.
This is an example in which two systems are provided independently.

As a result, the general information includes the message transmitting device MSEG,
It is output to the hall display device DISPLAY via the information control device, local area network LANi, and hall controller HC ₂ , while the elevator operation information is displayed in the hall via the machine control device, local area network LANc, and hall controller HC _1. It is designed to be output to the device DISPLAY. That is, the hall display device DISPLAY has two input terminals, and at this time, the input from the hall controller HC ₁ is preferentially displayed over the input from the hall controller HC ₂ . is there.

Therefore, the feature of the embodiment of FIG. 5 is that the two control devices are independent, so that the modification of one does not affect the operation of the other.

A modified example of the embodiment shown in FIG. 5 is shown in FIG. 6. In the embodiment shown in FIG. 6, there is no connection line from the hall controller HC ₁ to the hall display device DISPLAY. Local area network between control units
Connected by LANci. As a result, the elevator operation information is output from the local area network LANci to the hall display device DISPLAY via the information control device, the local area network LAN ₁ and the hall controller HC ₂ . Therefore, the features of the embodiment of FIG. 6 are almost the same as those of the embodiment of FIG.

By the way, the above embodiment is an example of a single elevator (only #A machine), but next, the present invention is applied to an elevator system configured so that a plurality of elevators are managed and operated. An example of such a case will be described with reference to FIG.

In the embodiment of FIG. 7, general information is transmitted to each of the units #A, #B, and #C after passing through the group management control device and the local area network LANm, and thereafter, in the same manner as the embodiment of FIG. Is displayed on the hall display device DISPLAY of each unit.

Further, the display of the elevator operation information and the like are also processed in the same manner as in the embodiment of FIG.

It should be noted that the same applies to the case where a plurality of elevators are group-managed in the embodiments of FIGS. 5 and 6, and a group management control device that manages the information control device is separately provided, and through this, It suffices if the information is output to the hall display device DISPLAY, and therefore its illustration is omitted.

Next, the operation of each unit in each of the above embodiments will be described in more detail.

First, FIG. 8 shows the internal software configuration of the hall controller HC ₁ in the embodiment of FIG.
Inside this hall controller HC ₁ , the communication task TAS
K ₁ c, elevator status display task TASK _2, it has three tasks of message display task TASK _3, each task is multi-tasking at a treatment level as shown in Figure 9. That is, the message display task TASK ₃ is set at a lower level than other tasks, and therefore, even when the message display task TASK ₃ is executed, another task having a higher priority than this, for example, When the elevator status display task TASK ₂ is activated, the processing of this message display task TASK ₃ is interrupted, and the processing moves from there to the elevator status display task TASK ₂ .

Therefore, the elevator status display task TASK ₂ now displays the elevator operation information in the message display task TASK.
_{If the} general information is displayed and output at the same time in ₃ , the elevator operation information is displayed and processed in preference to the general information. In FIG. 8, when the communication task TASK ₁ c has communication data, and when the other elevator status display task TASK ₂ and the message display task TASK ₃ have an activation factor in this communication task TASK ₁ c. , Respectively (task generation).

Next, FIGS. 10 and 11 are explanatory diagrams of the detailed contents of communication data. First, as shown in FIG. 10, this communication data is roughly classified into elevator control data and message data.
It becomes a seed. The former corresponds to elevator operation information, and the latter corresponds to general information.

Here, as is apparent from FIG. 10, the message data is composed of a message control for controlling the message, a message pointer for storing the start address of the message buffer, and EOF indicating the end of the message pointer. On the other hand, the message buffer is composed of a display control and a message data group for controlling scrolling of message display and the number of times of repeated display.

Further, FIG. 11 is a detail of a part of the data shown in FIG. 10. First, FIG. 11 (a) shows the contents of the operating state of the elevator control data. Automatic; Automatic operation ii) Failure; Failure iii) Control; Control operation in progress iv) Maintenance; Maintenance operation in progress v) Spare; Not used.

Next, FIG. 11 (b) shows the contents of the message control of the message data, which is as follows.

That is, i) SKiP; a flag indicating whether or not message data is skipped. When "1" is skipped, when "0" is displayed. In addition,
Each bit corresponds to each message No. ii) STOP; a flag that controls the display stop of the message. Stop when "1", display when "0" iii) Reserved; not used Next, FIG. 11 (c) ) Is the contents of the message buffer,
It is as follows.

<Display control> i) SCROLL; Scrolling, scroll direction ii) TiMES; Message repeat display count iii) DEKAY; Repeat display repeat time interval <Data attribute> i) BL; Plink control ii) COLOR; Color not shown iii) RV; Reverse control iv) Reserved; not used <Code of data 1> i) CODO; Character code Next, FIG. 12 shows an example of task configuration in the case of the embodiment of FIG. The hall controller HC ₁ activates the elevator status display task TASK ₂ and the hall controller HC ₂ activates the message display task TASK ₂ . At this time, the priority processing of the task is determined by the level of the hardware interrupt inside the hall display device DISPLAY. Also in this example, the communication data is the same as that in the embodiment of FIG.

Next, detailed flows of these tasks will be described below.

FIG. 13 is a processing flow of the communication task TASK ₁ , step 1a is a communication data transmission processing with the local network LANc, step 1b is a processing for detecting a condition for activating the elevator status display task TASK ₂ , As described above, one of the five types of processing is selected. When the conditions are satisfied, the elevator status display task TASK ₂ is activated in steps 1c and 1d. Furthermore, when the message display task TASK ₃ is stopped (not in RAN) and the stop flag is not set, the message display task TA
SK ₃ is activated in steps 1e and 1f.

Next, Fig. 14 shows an elevator status display task TASK ₂
In the processing flow of Fig. 13, while the predetermined condition is satisfied in step 1b (Fig. 13) of the communication task, the operating state of the elevator is displayed at regular intervals in steps 2a to 2i, but the predetermined condition is not satisfied. If it is, the self task is extinguished in step 2j and the task processing is terminated. It should be noted that the specific processing of activating and erasing the task at this time is controlled by software of an operating system (OS) (not shown).

Next, the processing flow of the message display task TASK ₃ will be described with reference to FIG. This task is shown in Figure 10 and
It is processed based on the contents of the message control and display control shown in FIG.

In step 3a, the display skip flag SKiP is checked, and if this flag is not present, the process directly loops to the next message processing. Only when the stop flag STOP is not set in step 3b, the process proceeds to step 3c, and the message is output to the display unit according to the attributes such as COROL, BL, and REV. At this time, the display modes such as the scroll instruction SCROL, the display count TiMES, and the delay time DELAY are selected for each message by the processing of steps 3d, 3e, and 3f.

Then, after confirming that all the messages have been displayed in step 3g, the self task is started after a certain time in step 3h for the periodic display.

On the other hand, when the stop flag STOP is set by the machine control device or the information control device, this invoking task disappears. The conditions for disappearance at this time are as follows from the viewpoint of energy saving.

i) When a predetermined time (for example, at night) is reached ii) When the elevator is not used for a predetermined time (for example, 30 minutes) or more. FIG. 16 is an example of a screen format in the message transmission device MSEG. For data input, for example, a keyboard can be used.

〔The invention's effect〕

According to the present invention, i) When a predetermined condition in the elevator operation information is satisfied, the elevator operation state is displayed with priority over the general information, so that a display that matches the psychological state of waiting passengers can be obtained. , The frustration is resolved.

ii) Since elevator driving information and general information are commonly displayed in one hall display device, waiting passengers only need to pay attention to one display device, and the psychological burden is small. .

iii) There is no need to increase the number of hall display devices, and the cost is low.
