Description

Description: TECHNICAL FIELD The present invention relates to an elevator control device, and more particularly, to an elevator control device that is used for elevator control or the like to enable better elevator control. The present invention relates to an elevator usage status collection device that collects usage status data.

[Prior Art] As a conventional technology for collecting data for statistically processing the usage status of an elevator, for example, Japanese Patent Application Laid-Open No. 60-161.
The technique described in Japanese Patent No. 878 is known. In this type of conventional technology, the number of operations, the number of hall calls, the duration of hall calls, the number of times of occupancy, the number of times of occupancy, etc. are generally adopted as data to be collected for statistically processing the usage status.

In addition, as the collected data in the group management elevator system of the reservation light system, the number of times the reservation lights are changed, the number of first arrivals of elevators other than the reservation lamp lighting unit, etc.
It is adopted in addition to the above-mentioned collected data.

These collected data are ratios to the total number of times the elevator is operated, for example, the full-occupancy ratio, or the ratio to the total number of calls, such as the long-lasting ratio of 60 seconds or more
Generally, statistical processing is performed such as the full-occupancy rate, reservation change rate, first-come-first-served rate, and the like. Then, the result of the statistical processing as described above is presented to the customer in the form of a table, a graph, or the like, or is used as data for determining a control parameter for controlling the elevator.

[Problems to be Solved by the Invention] The result data obtained by the statistical processing of the collected data according to the above-described conventional technique does not always match the feeling of a human being who is an elevator user. Such an example will be specifically described with reference to FIG.

FIG. 5 is a graph showing the number of people in the car for each operation of the elevator. The horizontal axis shows the number of times of operation, and the vertical axis shows the number of people in the car at each operation time.

As can be seen from FIG. 5, the number of people in the car during the first operation is one, and the number of people in the car during the second operation is three. Then, in FIG. 5, the number of people in the car for each operation is shown for a total of 10 operations. Further, it is assumed that the full capacity operation rate is obtained from FIG. 5, and the criterion for full capacity is provisionally defined as the case where the number of people in the car is 18 or more.

In the example shown in FIG. 5, 20 people are in the car only at the time of the seventh operation, and the number of full operation is counted as one. Therefore, the full-occupancy rate in this example can be calculated by the following equation (1), and is 10%.

The above-mentioned full-occupancy rate is the number of times the vehicle has been fully occupied with respect to the total number of times of operation.Here, from a different perspective, the number of users who encounter full capacity and the total number of users are calculated. When this is calculated, the ratio of the number of full-packed encounters can be calculated by the following equation (2).

In the example shown in FIG. 5, all users, that is, the total number of people in the car during all driving is 30, and the total number of people who have driven 18 people or more is 20 in the 7th time. Therefore, when these values are put into the equation (2), the ratio of the number of full-packed encounters is calculated as 67%. This means that 67% of all users in the 10 times of driving got into the fully-equipped elevator and felt full. Considering that it is the user who makes the value judgment in the elevator, the evaluation is more similar to the user's feeling when it is carried out by the ratio of the number of full-capital encounters than by the above-mentioned full-occupancy rate. It can be performed.

As described above, the evaluation method that does not match the human sense includes not only the evaluation of fullness, but also the evaluation of the reservation change rate in the reservation light type elevator, for example.

That is, in general, the reservation change rate can be represented by the number of reservation change calls with respect to the total number of calls, as shown in equation (3).

Now, if one of the 10 calls is a reservation change, the reservation change rate represented by the above equation (3) is 10%. However, suppose 10 calls make 3
Assuming that 0 people used, of which 20 were used by one call for which the reservation was changed, that is, 10 people were used by the other 9 calls, the above-mentioned equation (2) was used. If the ratio of people who have experienced a reservation change, that is, the ratio of people experiencing a reservation change, is calculated using equation (4), which is similar to, the ratio is 67%.

From the extreme point of view of the reservation change encounter number ratio mentioned above, even if the reservation of 9 calls out of 10 is changed, the reservation of the remaining 20 waiting calls must be changed. For example, the percentage of people who experience reservation changes is 33%, and it is judged from the human sense that there are few reservation changes.

As described above, the conventional technique only collects the statistical data corresponding to the evaluation criteria different from the human sense of the elevator user, that is, the equations (1) and (3) described above. However, there is a problem that the evaluation criteria that match the human sense, that is, the statistical data corresponding to the above-described equations (2) and (4) have not been collected.

An object of the present invention is to solve the above-mentioned problems of the conventional technology and collect the usage situation of an elevator equipped with a data collection means that can perform an evaluation close to the human sense, which is suitable for the human sense. To provide a device.

[Means for Solving the Problem] According to the present invention, the object is to detect the occurrence of a load or a congestion situation in a predetermined range defined in advance, and a predetermined situation detected (hereinafter, also referred to as an event). When happened,
Means for detecting the number of users who are present, means for adding and recording the detected number of people, and detecting and storing the total number of users including the number of people other than when the predetermined event occurs And means.

[Operation] As an example of a predetermined predetermined event, which occurs when the vehicle is fully loaded, in this case, the number of passengers in the car can be determined at each operation by the in-car load detector installed under the floor of the car. It is detected and a driving memory as described with reference to FIG. 5 is created. As a result, the total number of users and the number of users who have reached full capacity can be obtained. Then, when a suitable amount of data can be collected, the ratio of the number of full-occupancy encounters can be obtained by performing the calculation of the above-mentioned formula (2).

In addition, taking the event of a reservation change as a predetermined event, for example, in this case, the waiting person detector installed at the landing will detect the number of people waiting in the hall when the reservation change occurs, and this event occurrence The total number of users is calculated by adding the number of people waiting each time and detecting and adding the number of passengers on each floor for each elevator operation. Then, when an appropriate amount of data can be collected, the ratio of the number of encountering reservation changes can be obtained by performing the calculation of the above-mentioned formula (4).

The predetermined event need not be limited to the above-mentioned occurrence of full capacity and reservation change, and may be many other events as long as they have been the evaluation criteria of elevators in the past, for example, the passing rate and the first-come-first-served basis. It may be a rate, a long waiting rate, or the like. The present invention only needs to be provided with a means for detecting the occurrence of these preset events and a means for detecting the number of people in the hall or car when the event occurs, and in extreme cases, the car It is also possible to find the ratio of the number of people who have been involved in accidents of being trapped inside.

The result of the collected data statistically processed as described above is
From maintenance installation or elevator control device,
The data can be output in the form of a table or the like, and can be output in an easy-to-read form as data that fits human senses.

FIG. 6 (a) shows an example of the graph output obtained by the present invention, in which the horizontal axis shows the number of passengers in the car, and the vertical axis shows the ratio of the number of passengers who have encountered driving in that car. It is a distribution map of the encountering person ratio. Further, FIG. 6 (b) is an example of a graph output obtained by the conventional technique, and FIG. 6 (a)
The same operation result data as is shown as the distribution of the number of times of operation. Comparing FIGS. 6 (a) and 6 (b), it can be seen that the processing result by the conventional technique is significantly different from the human sense, and in the case of the present invention, it is close to the human sense. The processing result can be obtained.

It goes without saying that the statistical processing result of the data collected by the present invention as described above is not only used for display, but can also be used for determining the elevator control method by learning the processing result. . If such a processing result obtained by the present invention is used for controlling the elevator, for example, in a floor with many waiting customers, it is possible to control the elevator without changing the reservation, Also, if the current or predicted number of people in the car in the near future exceeds the average number of passengers,
The elevator can be controlled such as limiting the allocation of new calls.

It may depend on the method.

In the statistical processing of the collected data according to the present invention described above,
Some statistical data have a property that the same user may encounter the same event more than once, for example, in the case of a full-capacity encounter. Specifically, for example, there is a case where the first floor becomes full and stops on the second floor, and the fullness is not canceled at that time, and the vehicle stops on the third floor. In such a case, the present invention adds the total number of users and the number of users who have encountered a predetermined event for each operation to obtain the total number of users and the total number of users who have experienced a predetermined event. You can

Next, as an example of the operation of the embodiment of the present invention, an operation of obtaining the ratio of the total number of people who have encountered full capacity will be described with reference to the processing flow shown in FIG. The flow shown in FIG. 3 is activated, for example, every one second.

(1) First, it is determined whether the elevator has started operation. This judgment becomes "YES" only once at the start of operation of the elevator, and the process proceeds to step SA20. Otherwise, the process proceeds to step SA50 (step SA1).
0).

(2) It is determined which event in the congestion degree table WCT shown in FIG. 3 (b) the number of people in the car at departure belongs to. This congestion degree table WCT is 0-2 people, 3-5
It is composed of 7 data recording areas of people, ..., 15 to 17 people, 18 people or more, and each area shows the occurrence of the event of the congestion degree, and the contents in that area are used when the occurrence event was encountered. The number of persons (step SA20).

(3) Congestion degree table W determined in step SA20
Add the detected number of people in the car at the time of departure to the area of CT. For example, if the number of detected people is 7, add 7 to the recording area of 6 to 8 people of the congestion degree table WCT, and if the number of detected people is 20, add 20 to the recording area of 18 or more people. Add (step SA30).

(4) Next, the number of persons detected in step SA20 is set to the third
It is added to the total user record table WCM shown in FIG. 7B (step SA40).

(5) Next, it is determined whether or not there is a detection period end signal,
If not, the process ends, and if there is, the process proceeds to step SA60 (step SA50).

(6) In this step, the ratio of the total number of people who encounter full capacity WCR is calculated by statistical processing, and the data in the recording area of 18 or more people in the congestion degree table WCT is converted into the data in the total number of users recording table WCM. By dividing, the WCR of the total number of occurrences of full-occupancy encounters is calculated. Further, a process of obtaining a ratio for each recording area and creating a distribution is executed (step SA60).

(7) Next, all the data in the congestion degree table WCT and the total number of users recording table WCM are cleared to "0" and the processing is ended (step SA70).

The above-mentioned processing is performed every time the elevator starts operating,
The data for each operation is the table WCT, W described above.
Since it is sequentially added and held in the CM, step SA
When a detection period end signal is detected at 50, a sufficient amount of data for statistical processing is stored in the table WC.
It will be available in T, WCM. Although not shown, when there are a plurality of elevators, the processes of steps SA10 to SA40 are repeatedly executed for the number of elevators.

Next, the fourth operation for obtaining the reservation change encounter number ratio
It will be described with reference to the processing flow of FIG. 4A and the table shown in FIG. 4B used for this processing. This process is started periodically, for example, every one second.

(1) First, it is determined whether or not a reservation change has occurred, and if a reservation change has not occurred, the process proceeds to step SB40 (step SB10).

(2) When the occurrence of a reservation change is detected in step SB10, the number of waiting people is detected by the waiting number detecting device of the unit on the floor where the reservation change has occurred and the reservation lamp was lit before the occurrence of the reservation change. Perform (step SB20).

(3) Next, the reservation change recording table L shown in FIG. 4 (b)
The number of persons detected in step SB20 is added to the recording areas of the floor and the direction of the reservation change in CT (step SB3).
0).

(4) In order to obtain the total number of users, it is determined whether or not there are passengers, and if it is detected that there is a passenger, the number of passengers is added to the recording area of the floor and direction of the passenger table INT (step). SB40, SB50).

(5) Next, it is determined whether or not there is a detection period end signal, and if there is no end signal, the process ends, and if there is an end signal, statistical processing is performed in step SB70 (step SB60).

(6) The statistical process by this step is a process for obtaining the reservation change encounter number of passengers ratio LCR for each floor direction, and the data for each floor direction in the reservation change recording table LCT is stored in the same number on the same floor of the passenger number recording table INT. By dividing by the data, the reservation change encounter number of people ratio LCR is obtained. Further, these results are subjected to a distribution for each floor direction, or a process of obtaining a reservation change encountering person ratio when all floors are put together, etc. (step SB70).

(7) Next, all the data in the reservation change recording table LCT and the passenger number recording table INT are cleared, and the processing ends (step SB80).

In the above-described embodiment of the present invention, a waiting person detection device is installed in each floor hall to obtain the reservation change encountering person ratio as shown in FIG. 4 (a). If it cannot be installed, the effect can be improved by estimating and using the number of people who have encountered a reservation change. As a method of estimating the number of people who have experienced a reservation change, for example, the elapsed time from the registration of the hall call on that floor until the reservation change occurs, and the arrival time of the customer to the average hall on that floor There is a method of estimating by multiplying by the interval.

Fig. 7 shows the results of statistical processing as a bar graph,
An example of the output according to the present invention is shown, which simultaneously shows the number of passengers on each floor and the number of people who have encountered a reservation change. In FIG. 7, the shaded area is the number of people who have encountered a reservation change, and is the total number of users shown in white. Further, as an output example of another form of the statistical processing, it is also possible to display the contents shown in FIGS. 5 and 6 already described.

As described above, the results of the elevator usage status collection according to the embodiment of the present invention can be displayed in the form of a graph, and the evaluation content close to the human sense can be easily displayed.

It is also possible to control the operation of the elevator by using the data collected and statistically processed according to the present invention. As an example of the elevator control device that can be operated using such data, the present inventors have Have already proposed, for example, those described in Japanese Patent Application No. 63-145745.
