Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an elevator waiting number detection device for detecting the number of waiting passengers in each direction of an elevator hall.

(Prior Art) It is important to know the number of customers waiting in an elevator hall in order to provide optimal services that match traffic demand. For example, in a group management control elevator system, etc., in response to a hall call, the most suitable elevator for service is predictively selected based on the status information of each elevator, and the selected elevator is selected for the hall call. By assigning the information to the user and making the user respond, the service to the customer can be provided in a short time. However, if you are left behind in a hall where demand is particularly concentrated, the length of boarding and alighting times, and new car calls caused by passengers who have boarded the car operating the destination floor button on the car control panel, etc. This could lead to forecast failures (arrivals after the assigned seats) due to delays, which could aggravate dissatisfaction and suspicion among customers waiting in the hall.

Therefore, in order to comprehensively manage multiple machines to be controlled according to the situation and perform highly accurate group management control, it is essential to accurately grasp the number of customers waiting in the hall.

As described above, in an elevator system, it is important to understand the number of customers waiting in the hall in order to improve elevator user service, but the conventional technology cannot accurately detect the number of customers waiting in the hall. There was a problem in that it was difficult to distinguish between how many people were waiting in the ascending direction and how many people were waiting in the descending direction, and there were few opportunities for it to be adopted due to its accuracy and reliability.

Here, the following are typical methods of conventional waiting customer number detection devices. One is to spread a mat in the elevator hall, and under it are placed switches that are activated by load, and the approximate number of people is detected from the number of activated switches.The second is to use a camera mounted on the ceiling of the elevator hall. A third method detects the number of people based on the amount of far-infrared rays emitted by humans or its pattern. be.

Although some of these methods have been put into practical use,
Both methods have problems in that sufficient accuracy cannot be obtained, and in principle, the number of people waiting for each direction of ascending and descending directions cannot be determined. is not enough.

(Problem to be solved by the invention) In this way, in an elevator system, the number of people waiting in the hall can be grasped and the number of people waiting in the hall can be grasped and the number of people waiting in the hall can be ascertained. This is important in order to avoid prediction failures in service car allocation, but there are some points such as not being able to obtain sufficient accuracy in either case, and in principle not knowing the number of waiting passengers by direction of ascending/descending direction. However, there is a problem with this, and the numerical values cannot be used directly for optimal control of elevators.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an apparatus for detecting the number of customers waiting in an elevator hall, which can accurately detect the number of people waiting in an elevator hall and the direction in which each person is using the elevator.

[Structure of the invention]

(Means for solving problems) In order to achieve the above object, the present invention is configured as follows.

That is, this device includes a wireless card that is carried by a building visitor that generates a different signal for each individual, a detection means for detecting the signal generated by the wireless card provided in each elevator hall in the building, and a detection means for detecting the signal generated by the wireless card. Using the detection output, we can individually obtain the number of customers waiting in each elevator hall, and from the pre-memorized information for each individual such as the floor used -→→, we can grasp the direction of elevation and determine the number of customers waiting in each elevator hall! and a calculation means for obtaining information.

(Function) This device with such a configuration allows each person entering the building to carry a wireless card that generates a different signal for each individual, and within the building, detection means for detecting this is installed in each elevator hall, and a calculation means is used to detect this signal. Based on the detection output of the detection means, the waiting customers in each elevator hall are obtained individually, and the ascending and descending direction is grasped based on individual information such as the floor used - 4 which is stored in advance. ! It's about getting information.

Therefore, simply by having the user carry a wireless card, the number of customers waiting in the elevator hall can be detected and totaled by ascending direction and descending direction.Accurate information can be collected in real time, so The system detects the number of customers waiting in each direction for ascending and descending directions, and is useful for improving operation management, such as allocating multiple elevators and predicting fullness.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the system configuration of the device for detecting the number of waiting customers of the present invention. In the diagram, IA to IN control the operation of elevators A to N (No, A - No, N), respectively. The single control device 2 is a group management control device for efficiently operating a plurality of elevators. Reference numeral 14 denotes a waiting customer number general calculation device constituting the waiting customer number detection device, and 11a to l
ln is a bar antenna provided in the elevator hall of each floor, which constitutes the waiting customer number detection device. These bar antennas 1la-1in are for detecting received signals from ID cards, which will be described later. By having information such as the floor of the card, the bar antenna will be able to tell that the person holding the card has come to the elevator hall.
When obtained from ln, this memory registration content is referred to as information on the number of elevator customers waiting for the elevator, and information on the number of customers waiting for the elevator for each floor and direction is counted. This is then provided to the elevator group management device 2. The information to be registered in the memory of the total number of waiting customers calculating device 14 includes information on the ID card holder and the floor the holder is on, and information on directions.

The elevator group management device 2 also obtains car status information necessary for control, such as door opening/closing status of each car, car movement direction, car position, etc. from the single control devices IA to IN, and also obtains car status information necessary for control by floor and direction. The system calculates the number of customers waiting in the car, the load inside the car, etc., performs the optimum elevator hall for each hall call so as to provide the most suitable service, and causes the individual controllers LA, IB, etc. of the assigned elevators to respond. Give instructions.

Reference numeral 15 denotes a register, which is used to set and delete various information in the waiting customer number general calculation device 14.

The individual elevator control devices IA, IB, . . . are in charge of controlling a hoisting machine (not shown), car control, etc.

These devices detect the number of people boarding the car in the upward direction and the number of passengers in the downward direction based on changes in the output signal of an in-car load sensor installed under the floor of the elevator car. The elevator group management control device 2 can store the number of passengers for each ascending/descending period for each time period, and read the data when necessary.

Next, the waiting customer number integrated calculation device I4 is operated by the elevator group management device 2.
It inputs the passenger ratio for each elevator and the status of each elevator car, and calculates the number of waiting passengers for each elevator based on the number of ID card holders transmitted from the 10 cards and detected by the bar antenna 11. The number of waiting customers is calculated by the following formula and output to the group control device 2.
Output to.

Number of passengers waiting in the ascending direction - (Number of passengers in the ascending direction for each floor and time slot) ÷
(Number of passengers for each floor and time slot) Number of passengers) X (Number of 10 cards detected) ...(2
) Figure 2 shows a building to which the system of the present invention is applied. Visitors to the building 40 are required to carry an ID card 22 as shown in FIG. 3 in advance. This ID card 22 is required to display the visitor's photograph, name of affiliation, etc.

The ID card 22 has a built-in circuit shown in FIG.
Perform the following actions. That is, the power supply switch section 30, which performs switching control of the power supply in accordance with the command from the receiving section 36 which generates a power-on command using a signal transmitted from the switching antenna 17, energizes all circuits such as the calculation section 34 from the power supply section 32. In this calculation unit 34, the received signal from the reception unit 3G is calculated, and it is determined whether or not it is a calling signal for one's own ID card 22. When necessary, the notification unit 38 and the transmission unit 39 are activated to transmit the signal to the outside. Announcements and transmissions will be made.

In this ID card 22, normally the main circuit of the calculation section 34 is not energized, and a call signal from the outside is sent to the reception section 36.
The power switching unit 30 operates only when the signal is received by the power supply unit 32 to operate the main circuit of the calculation unit from the power supply unit 32, thereby extending the life of the power supply unit 32. Therefore, only the receiving section 3G is always in a standby state.

The transmitting section 39 can transmit a signal for identifying itself, such as a frequency different for each ID card, and the notifying section 38 can transmit different notifying signals depending on the different types of reception signals received by the receiving section 3G. can do. Therefore, the number of waiting customers total calculation unit 14 can always know in real time which ID card holders are in the hall and which ID card holders are present in the hall, and if they leave the hall, they are excluded from being counted as waiting customers in the hall. can do.

As shown in FIG. 2, a switching antenna 17 is arranged at the entrance of the building 40, and visitors pass through this switching antenna 17 at the entrance of the building. The power switch section 3o of the ID card is activated by the transmission signal from the switching antenna 17, the calculation section 34 starts operating, and a signal is transmitted from the transmission section 39, which is detected by the switching antenna 17. The outgoing signals from these ID cards 22 are stored in each hall in the building 40,
A relay device 12 for management is provided, and accordingly, the relay device 12 stores each person who passes by, and supplies the stored contents to the central processing unit 14 as necessary.

In such a configuration, visitors must submit their ID card 22 in advance.
Visitors are handed an ID card 22 at the reception desk. Each person will be required to carry these items with them when entering the building. In this case, the handed ID card 22 has different oscillation frequencies depending on the degree of need, thereby identifying the card holder. In this way, visitors can use the switching antenna 17, the bar antennas lla, llb,
. . , etc., the repeater 12 knows that it is located at a specific location in a specific hierarchy. The central processing unit 14 receives signals from the repeater 12 as necessary, and grasps the number of people present at each floor and at each location such as the elevator hall.

FIG. 5 shows an ID card information registration table. The ID card possessed by the visitor or visitor transmits a code that includes an identification code, and the ID information is associated with this code and sent to the terminal or register 15 of the waiting number general calculation unit 14. Information stored in memory. The ID information includes the floor where the person is enrolled, name, etc.

FIG. 6 shows a functional flowchart of the present invention.

The operation of this device will be explained with reference to this flowchart.

First, by operating the keys on the register 15, information such as the identification code of the ID card, the floor you are on, the floor you are visiting, your name, age, weight, etc. is stored in advance in the information memory in the number of waiting customers general calculation unit 14 ( Step SO). The general calculation unit 14 has a program for calculating the number of customers waiting. When the ID card approaches the bar antenna, the main circuit power of the ID card is turned on by the electromagnetic energy from the bar antenna.
The identification code of the D card 22 is transmitted (SL, S2).

This identification code is, for example, r0OOIJ.

The bar antenna receives this and provides it to the repeater 12, where it is stored. The waiting customer number general calculation device 14 reads this, and also extracts the current floor or visiting floor data stored in the memory of the waiting customer number general calculation device 14, and compares it with the floor where the bar antenna is installed. , distinguish between customers waiting in the ascending direction and descending direction, and add 1 to the table of the number of customers waiting in the ascending direction or descending direction (S4.S5.S9). The number of waiting customers is counted for all the approaching ID cards, and the resulting number of waiting customers for each elevator direction in each hall is transmitted to the elevator group management system as the current number of waiting customers information (S6, S7).

In this way, this device allows each person entering the building to carry a wireless card that generates a different signal for each individual, and detecting means for detecting this is installed in each elevator hall within the building. It is configured by providing a calculation means for obtaining the waiting customers of each elevator hall individually, grasping the ascending and descending directions based on individual information such as floor used and weight stored in advance, and obtaining information on the waiting customers of each elevator hall. It is something.

Therefore, simply by having the user carry a wireless card, the number of customers waiting in the elevator hall can be detected and totaled by ascending direction and descending direction.Accurate information can be collected in real time, so The system detects the number of customers waiting in each direction for ascending and descending directions, which is useful for allocating multiple elevators and improving operation management such as when J1 is expected to be full.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within the scope without changing the gist thereof.
