[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one configuration example of the present invention. As shown in FIG. 1, hall buttons 101 to 110 are installed in the halls on the first to tenth floors, and a car button 21 is installed in the car 2. Signals from the landing buttons 101 to 110 and the car button 21 are sent to the elevator control device 3. The elevator controller 3 determines which call the elevator will respond to, drives the motor 4 and, via the sheave 5,
Move the car 2 to the target floor. The operation status investigation device 6 receives the call occurrence status, the car position information, and the like from the elevator control device 3 and determines whether or not the floor on which the elevator user has boarded the elevator and the floor on which the elevator is waiting match. Judgment is made, and the ratio of the elevator standing by at that floor before the elevator user appears at the landing among the total number of hall calls is calculated, and the result is output using the display device 7 such as a display or a printer. The operation status investigation device 6 includes an I / O 63 as an interface unit with other devices, a RAM 64 for recording the operation status and the like, and a ROM 65 for storing programs and the like for the CPU 61 via the bus 62. It has a connected configuration. And I /
The elevator control device 3 and the display device 7 are connected to O63.

In FIG. 1, although the processing result of the operation status investigation device is displayed on the spot by the display device 7, it is described.
The data may be recorded and output on a floppy disk or the like so that the processing result of the operation status inspection device 6 can be seen in a place other than the place where the operation status inspection device 6 is installed, or the data may be output via a telephone line or a LAN. May be transmitted directly.

In FIG. 1, an operation status investigation device 6 is provided separately from the elevator control device 3.
However, the function may be provided inside the elevator control device 3 and integrated therewith.

In FIG. 1, the operation status investigation device 6 is configured to receive call registration information and the like from the elevator control device 3 in consideration of convenience of data transfer and the like. Even if the call registration information is obtained, the same function can be realized.

Next, a process for determining whether or not to wait in advance will be described with reference to flowcharts shown in FIGS. When the elevator is kept on standby, there are two possible modes: a door closing standby mode in which the elevator door is closed and waiting, and a door opening standby mode in which the elevator door is opened and waiting. FIG. 2 shows the door closing standby mode. FIG. 3 shows the case of the open standby mode.

In FIG. 2, when the occurrence of a hall call is determined in step S1 (hereinafter, step is omitted), it is determined in S2 whether there is a call other than the hall call. When the hall call is generated, the fact that there is a call other than the call means that the elevator was not in the standby state, and the processing is terminated. If there is no call other than the landing call that occurred, it is determined that the elevator was in a standby state,
In S3, it is determined whether or not the position of the floor where the elevator is stopped matches the position of the floor where the hall call has occurred. If they match, it is determined in S4 that it is in advance standby, and the process ends.

In the door open standby mode shown in FIG. 3, when the occurrence of a car call is determined in S5, it is determined in S6 whether there is a call other than the car call. When a car call is generated, the fact that there is a call other than the call means that the elevator was not in the standby state, and the processing is terminated. There are three cases in which a car call occurs without a call being registered. The first is when the passenger gets into the elevator waiting for the door to open and presses the button. The second is when the user pushes the hall button, calls the elevator, gets into the elevator, and presses the car button. Also in this case, the registration of the hall call is terminated when the elevator arrives at the floor where the hall call occurs, so it is determined that the car call has been generated without the call being registered. The third case is, for example, a case where two users from the certain floor get into the elevator and have finished responding to the first user's car call, and the second user presses the car button. Also in this case, since the registration of the car call is terminated when the elevator arrives at the destination floor of the car call, it is determined that the car call has occurred without any call registration. In step S7, it is determined that the floor at which the car call has occurred is not the floor that responded to the hall call or the car call so that the second and third cases are not determined to be in advance standby. If the floor has not been responded to by the hall call or the car call, it is determined in S8 that the waiting is in advance and the process is terminated.

In the above description, the information of the landing button and the car button is used to detect that the elevator user has got into the elevator. However, the information of the car load detecting device and the monitoring camera is used. The same function can be realized even by using this function. The pre-standby determination process in that case will be described with reference to the flowchart shown in FIG.

In step S9, it is determined whether the user of the elevator has entered the vehicle. When the in-car load detecting device is used, the determination is made by detecting that the load in the car has changed from 0 to a value equal to or more than a predetermined value. Since the load detection device in a car generally has low accuracy and can measure only in a unit of about 30 kg, it is preferable to set the predetermined value to the maximum accuracy of the detection device. Even an accuracy of about 30 kg is enough to detect that an elevator user has boarded the elevator. When a surveillance camera is used, an image in an empty car is stored in advance, and a difference from the current image is obtained, so that it is possible to detect that the user has entered the elevator.

In S10, it is determined whether or not the elevator has waited in advance. In this case, there are two methods. The first method is a method of judging pre-standby by judging that the floor at which the user's entry has been detected is not the floor responding to the hall call or car call in the same manner as in S7 of FIG. The second is to wait in advance by determining that the elevator has stopped at the floor where the user's entry was detected a predetermined time (for example, 10 seconds) before the time when the user's entry was detected. This is a method of determining. Elevators typically take about 2 seconds to open the door and about 3 seconds for one person to get into the elevator, so the elevator will be on the floor at least 5 seconds before the detection of the passenger's entry. If stopped, the elevator is considered to be waiting on that floor. The second method lacks the accuracy of the determination compared to the first method, but because the advance standby can be determined only by the information of the time and the stop position of the elevator, the information of the hall call or the car call may be determined under some conditions. This is an effective judgment method when it cannot be obtained.

FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, and FIG.

FIG. 5 shows the result of dividing the number of times of waiting in advance by the total number of hall calls (hereinafter referred to as the prior waiting success rate) every hour. As a result, it is possible to see at a glance in which time zone of the day the advance standby is being performed, so that it is possible to determine whether the effect of the advance standby is exerted in a time zone such as when going to work, when leaving the office, or when the time is idle. Although FIG. 5 shows that the preliminary waiting success rate is displayed every hour, the time width may be changed according to the customer's request and the like.

FIG. 6 shows the number of pre-standbys, the number of hall calls, and the pre-standby success rate in each time zone and day. Since the number of hall calls and the advance waiting success rate can be compared, the relationship between the large traffic volume (large number of hall calls) and the prior waiting success rate can be easily understood. Also, since the pre-standby success rate for the entire day is known, the effect of the pre-standby as a whole can be confirmed. Although not shown in FIG. 6, by adding the average waiting time for each time zone or for one day to the table, it is possible to confirm the effect of shortening the waiting time by the preliminary waiting.

In FIG. 5 and FIG. 6, the pre-standby success rate in each time zone is described for the entire building. However, the pre-standby success rate for each floor allows the effect of pre-standby to be known in more detail.

FIG. 7 shows a pre-standby success rate for a specific period (for example, one hour, one day, or one week) of each floor. Thereby, the pre-standby success rate of a specific floor (lobby floor, VIP floor, etc.) can be easily known.

FIG. 8 shows an elevator operation diagram, in which the vertical axis represents floors and the horizontal axis represents time. Here, the operation from the floor where the elevator is on standby or in advance is indicated by a solid line, and the operation for a hall call generated from a floor different from the floor on which the elevator is on standby is indicated by a dotted line. The floor set as the standby floor is shaded. The destination floor by the car call is indicated by a square, and the landing call in the descending direction is indicated by a downward triangle. Although not shown in FIG. 8, the landing call in the ascending direction is indicated by an upward triangle. By expressing the operating status of the elevator in this way, it is possible to know the operating status related to the preliminary standby in detail.

FIG. 8 shows a case where the waiting floor is changed in a short time. This shows a case where the time at which the passenger appears at the landing is predicted, and the waiting floor is changed accordingly. Here, a numerical value (hereinafter, referred to as a standby floor change number) divided by the number of times the standby floor can be preliminarily divided by the number of times the standby floor is changed (hereinafter, referred to as standby floor change number)
(Referred to as “substantial pre-standby success rate”), it is possible to explain to the customer how much of the number of pre-standby attempts was successful. FIG. 9 is an example of the display, and shows the number of preliminary standbys in each time zone, the number of changes in the standby floor, and the actual preliminary standby success rate. Note that, as shown in FIG. 7, the actual pre-standby success rate is displayed for each floor, and the specific floor (the lobby floor or the V floor) is displayed.
The actual pre-standby success rate of the IP floor etc. may be explained to the customer.

FIG. 10 shows the operation status of the elevator in chronological order. Here, the black part indicates driving in advance standby, the shaded part indicates driving for a hall call generated from a floor different from the floor where the elevator was waiting, and the white white part indicates that the elevator is waiting. Is shown.
However, the movement time of the elevator due to the change of the standby floor is also represented as being in standby. By expressing in this manner, the ratio of the operation by the preliminary standby to the entire operation can be easily understood. If the standby operation is considered to be a preparation for driving in advance standby, the standby operation and the operation in advance standby may be indicated without distinction.

[0026]

According to the present invention, prior waiting is determined by detecting that a passenger has entered a waiting elevator, and the ratio of the number of prior waiting and the total number of hall calls or the state of prior waiting is illustrated. As a result, even customers who do not have expertise in elevators can confirm the effect of waiting in advance.
