  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an optimal control system according to the number of objects according to the first embodiment of the present invention. As shown in the figure, in this embodiment, a plurality of areas 1, 2,..., N are set in advance as independent areas for performing predetermined management. In each area 1 to n, management objects 11, 12,. As the management objects 11 to 1n, the drive itself is controlled, for example, an elevator, etc. The physical quantity such as temperature, humidity, pressure, water volume, wind power, illuminance, thermal power, etc. are controlled, such as an air conditioner, etc. There is no special restriction as long as it is an object to be controlled.

  The wireless terminals 31, 32, 33, 34, and 35 are assigned to each of the plurality of detection targets in a one-to-one correspondence, and predetermined terminal signals S1, S2, S3, and S4 are transmitted through the respective transmitters incorporated therein. , S5 is transmitted wirelessly.

  Here, the detection target may be any of a person, an object, and an animal that are targets for grasping the number. When the detection target is a person, the wireless terminals 31 to 35 are worn by each person to be detected as a wearable watch or an ID card, for example. When the detection target is an object, an animal, etc., the wireless terminals Reference numerals 31 to 35 are attached to an object to be detected or an animal in the form of an IC tag, for example. The detection target in the present embodiment freely moves around the space, and thus the wireless terminals 31 to 35 also move together with the detection target.

  The terminal signals S1 to S5 are specific to the wireless terminals 31 to 35, respectively. This is because the oscillation frequency of each transmitter incorporated in each wireless terminal 31 to 35 is specific to each wireless terminal 31 to 35, and the terminal signals S1 to S5 are specific to each wireless terminal 31 to 35. It can be easily realized by including code information.

  Receiving terminals 21, 22,..., 2 n are arranged in each of the areas 1 to 1 n and receive signals including at least information indicating the number of radio terminals 31 to 35 that have received and received the terminal signals. S11, S12,..., S1n are sent to the management server 51 via the communication network (for example, the Internet) 41.

  More specifically, as shown in FIG. 2 (a), the receiving terminals 21 to 2n receive the terminal signals S1 to S5, and the receiver 211 receives the terminal signals S1 to S5. The signal processing unit 212 that processes the terminal signals S1 to S5 to detect the type (number) and outputs the received signals S11 to S1n including at least information indicating the number, and the ID that identifies each receiving terminal 21 to 2n And a transmitter 213 that sends received signals S11 to S1n output from the signal processing unit 212 together with information to the communication network 41.

  Thus, the number of detection targets (for example, people) existing in each area 1 to n through the types of terminal signals S1 to S3 and S5 sent by the wireless terminals 31 to 33 and 35 existing in each area 1 to n. Information can be transmitted to the management server 51.

  The management server 51 receives and processes each received signal S11 to S1n together with ID information that identifies each receiving terminal 21 to 2n, and at least includes elements based on the number of wireless terminals 31 to 35 for each area 1 to n. In addition, predetermined control of each of the management objects 11 to 1n is performed by the control signals C1, C2,.

  More specifically, as shown in FIG. 2B, the management server 51 according to this embodiment includes a receiving unit 511, a quantity detecting unit 512, an arithmetic processing unit 513, and a transmitting unit 514. Among these, the receiving unit 511 receives and stores the received signals S11 to S1n together with ID information specifying the receiving terminals 21 to 2n. The quantity detection unit 512 processes the ID information specifying each reception terminal 21 to 2n stored in the reception unit 511 and each reception signal S11 to S1n, and detects the number of detection targets for each area 1 to n. . The arithmetic processing unit 513 processes the quantity information sent out by the quantity detection unit 512 and takes into account the contents stored in the management information storage unit 53 in accordance with the number of detection targets in each area 1 to n. Control signals C1 to Cn for performing control on the management objects 11 to 1n are formed. The transmission unit 514 transmits the control signals C1 to Cn formed by the arithmetic processing unit 513 together with the ID information specifying each management target 11 to 1n to the management targets C1 to Cn via the communication network 41.

  On the other hand, the management information storage means 53 stores control contents in advance so as to perform appropriate control according to at least the number of detection targets in each area 1 to n through the management server 51. For example, whether or not there are wireless terminals 31 to 35 in each area 1 to n, the number of wireless terminals 31 to 35 in each area 1 to n, or the number of wireless terminals 31 to 35 in each area 1 to n exceeds a predetermined number The contents of control of the management objects 11 to 1n are changed depending on whether or not.

  When the detection target is a person, the number of persons existing in each of the areas 1 to n is grasped. FIG. 1 shows a case where there are three people in area 1, one in area 2, and zero in area n. The wireless terminal 34 does not belong to any of the areas 1 to n. That is, since the wireless terminals 31 to 35 move integrally with a detection object such as a person who freely moves around, the wireless terminals 31 to 35 freely enter and exit each area 1 to n.

  Here, the communication between the wireless terminals 31 to 35 and the receiving terminals 21 to 2n in the present embodiment can be suitably realized by using Bluetooth communication. The sizes of the areas 1 to n depend on the radio wave intensity of the terminal signals S1 to S5 transmitted from the wireless terminals 31 to 35 and the reception sensitivity of the receiving terminals 21 to 2n.

  Therefore, by actively utilizing this, a threshold is set for the reception sensitivity of the receiving terminals 21 to 2n, and when the intensity of the radio waves transmitted from the wireless terminals 31 to 35 is equal to or higher than the threshold, the receiving terminals 21 to 2n May be configured to determine that the wireless terminals 31 to 35 are in the areas 1 to n. Specifically, a radio wave intensity detection sensor is built in the receiver 211 of each of the receiving terminals 21 to 2n, and the radio wave intensity detection sensor is detected when the radio wave intensity detected by the radio wave intensity detection sensor is equal to or greater than a threshold value. Is configured to start receiving the terminal signals S1 to S5 by the receiving terminals 21 to 2n with the switching signal transmitted from the terminal.

  In addition, when the detection target is, for example, a person, the wireless terminals 31 to 35 may be configured to send together the ID information of the person who has each of the wireless terminals 31 to 35. When configured to transmit, the receiving terminals 21 to 2n also transmit the ID information to the management server 51 including the received signals S11 to S1n.

  More specifically, in this case, the ID information is stored in association with the owner's information in the signal processing unit 212 of each receiving terminal 21 to 2n, and the terminal signals S1 to Sn are processed. The ID information is included in the received signals S11 to S1n output from the signal processing unit 212 by matching with the ID information included in each terminal signal S1 to Sn and sent to the management server 51 via the transmitter 213. To do.

  As a result, it is possible to control each of the management targets 11 to 1n using the ID information of the detection target in the management server 51 by the control procedure stored in the management information storage unit 53 by the arithmetic processing unit of the management server 51. As a result, for example, when the presence of a VIP is detected, it is possible to control the appropriate management objects 11 to 1n.

  The clock unit 52 provides time information to the arithmetic processing unit 513 of the management server 51, whereby the arithmetic processing unit 513 takes into account the management information storage unit 53 and appropriately controls the management target in consideration of the time information. The control signals C1 to Cn for performing are formed. For example, even when reception signals S11 to S1n having the same contents are received, flexible control such as changing the control contents for the management objects 11 to 1n in a time zone such as morning, noon, and night can be performed.

  According to the present embodiment, the management objects 11 to 1n arranged in each area 1 to n can be controlled in consideration of the number of detection objects existing in each area 1 to n. Therefore, it is possible to prevent unnecessary operations of the management objects 11 to 1n, such as directing an elevator to the room or cooling or heating a room where no one is present, and perform optimal control.

  Here, a specific embodiment will be described in which the management objects 11 to 1n are elevators on each floor, and each person who is a detection object is wearing an ID card that is the wireless terminals 31 to 35. Areas 1 to n in the present embodiment are spaces of a predetermined area in front of each elevator where a person waiting for the elevator stands.

  According to the present embodiment, a waiting person who preferentially sends an elevator to the area 1 having the largest number of people waiting at the management server 51 based on the control procedure stored in the management information storage means 53. Optimal control reflecting the number of In this case, it is desirable that a plurality of elevators are operated in parallel. This is because an elevator may pass depending on the number of people waiting in areas 1 to n.

  As described above, when operating a plurality of elevators in parallel, each column is controlled by the optimal control system according to the present embodiment, and a plurality of elevators are controlled while exchanging control information for each optimal control system in each column. More efficient control can be performed by controlling the operation of the entire elevator system.

  In the present embodiment, the wireless terminals 31 to 35 are ID cards, and can include ID information indicating the attributes of the person wearing the ID card. , It is possible to perform priority control such that the management server 51 preferentially sends an elevator to the floor where the VIP stands by based on this information.

  FIG. 3 is a block diagram showing an optimal control system according to the number of objects according to the second embodiment of the present invention. As shown in the figure, the present embodiment has a central receiving terminal 71 that supervises the receiving terminals 21, 22, and 23 in the areas 61, 62, and 63, but the other configuration is basically the first shown in FIG. This is the same as the embodiment. Therefore, the same parts are denoted by the same reference numerals, and redundant description is omitted.

  The areas 61 to 63 according to this embodiment are closed spaces such as rooms in a building partitioned by walls or the like. In this case, the receiving terminal 21 arranged in each area 61 to 63 receives the terminal signals S1, S2, S3 and S4 from the wireless terminals 31, 32, 33 and 34 existing in each area 61 to 63. The reception signals S11, S12, S13 transmitted from the reception terminals 21 to 23 are collected by the general reception terminal 61 by radio, and transmitted from the general radio terminal 61 to the management server 51 through the communication network 41 as the general reception signal S. The That is, the overall receiving terminal 61 sends a receiver that receives the terminal signals S11 to S13 and the terminal signals S11 to S13 received by the receiver to the communication network 41 together with ID information that identifies the receiving terminals 21 to 2n. And a transmitter.

  Thus, by providing the general reception terminal 61 and transmitting the information in multiple stages, communication between the reception terminals 21 to 23, which are fixed stations, and the general reception terminal 61 is performed with sufficiently high output. The wireless terminals 31 to 35 only need to be able to communicate with the receiving terminals 21 to 23 existing in the vicinity, so that the outputs of the wireless terminals 31 to 35 can be reduced accordingly. As a result, the wireless terminals 31 to 35, which are portable terminals, can be reduced in size, and can be made highly portable.

  The sensor 71 is an optional component, but can be attached to the wireless terminal 34. In this case, the state of the detection target that is the detection content of the sensor 71 is reflected in the control of the management targets 11, 12, and 13 by the management server 51. For example, when the wireless terminal 34 belongs to a person to be detected, the pulse 71, body temperature, etc. of the person is detected by the sensor 71, so that the control of the management target 12 that is an air conditioner is matched to the state of the person to which the wireless terminal 34 belongs. Perform optimal control. In this case, information of the sensor 71 is exchanged between the wireless terminal 34 and the receiving terminal 23 by bidirectional communication.

  That is, as shown in FIG. 4, the wireless terminal 34 wirelessly transmits the predetermined sensing information SS output from the sensor 71 by including it in the terminal signal S4 from the built-in transmission unit 341, and receives the reception terminal 23, the overall reception terminal 61, and the communication. The data is sent to the management server 51 via the network 41. In the management server 51, the receiving unit 511 separates the sensing information SS and supplies it to the arithmetic processing unit 513. The arithmetic processing unit 513 analyzes the sensing information SS and refers to the storage content of the management information storage unit 53 to determine the optimal control content of the management target 1n. At the same time, a control signal CS for the sensor 71 is also formed.

  In this case, the transmission unit 514 of the management server 51 sends the control signal C3 to the management target 13 and also sends the control signal CS to the sensor 71. For these two types of signals, for example, by adopting a frequency multiplexing method, only signals necessary on the receiving side can be separated and selected.

  Furthermore, the general receiving terminal 61 and the receiving terminal 23 in this case also form a transmission system for the control signal CS sent from the management server 51. That is, the general receiving terminal 61 receives the control signal CS sent from the management server 51 and wirelessly transmits the control signal CS, and the receiving terminal 23 receives the control signal CS sent from the general receiving terminal 61. Each is provided with a transmission / reception unit 231 that wirelessly transmits this. In addition, the wireless terminal 34 includes a receiving unit 341 that receives the control signal CS transmitted from the receiving terminal 34 and supplies the control signal CS to the sensor 71.

  Thus, the control signal CS for the sensor 71 sent out by the arithmetic processing unit 513 can also be sent to the sensor 71 via the management server 51, the general receiving terminal 61, the receiving terminal 23, and the wireless terminal 34. The sensor 71 sends the sensing information requested by the control signal CS to the management server 51 side. The sensing information SS at this time is, for example, a pulse, a body temperature, or the like. Therefore, by assigning a unique control signal CS corresponding to the type of sensing target, desired sensing information SS can be selectively transmitted to the management server 51.

  In the figure, the sensor 71 is attached only to the wireless terminal 34, but of course, it can be attached to the other wireless terminals 31 to 33.

  Here, a specific example in which the areas 61 to 63 are each room of the building, the management objects 11 to 13 are the air conditioners in each room, and the detection objects are persons in each room will be described.

  According to the present embodiment, based on the control procedure stored in the management information storage means 53, the management server 51 grasps the number of people existing in each of the areas 61 to 63 and performs optimum control according to the number of people. . That is, the area 61 with a large number of people performs optimal control with the control contents stored in the management information storage unit 53 in advance according to the number of people. On the other hand, since there is no person in the area 62, the air conditioner device to be managed in this area 62 is not driven. The air conditioner device that is the management target of the area 63 performs optimal control according to the state of the person who is the detection target to which the wireless terminal 34 detected by the sensor 71 belongs.

  In the embodiments and examples described above, the case where the detection target is a person has been described as moving in space, but it is not necessary to move. In short, as long as it is configured so that optimal control reflecting the number of detection targets is performed, for example, when the detection target is a product and this product is stored in a refrigerator and sold, It is also possible to perform cooling according to the number of products. In this case, management of this product can be performed together using information on the number of products.

The input unit 176 is an input unit such as a button switch, and a signal is output to the control unit 173 in accordance with a user operation. The storage means 177 is a storage means used as a temporary work area when storing programs, storing various data, and performing calculations.

  Next, the operation of the optimal control system according to the third embodiment of the present invention will be described. It is assumed that each wireless terminal is attached to a user at a rate of one person, and the user is in a room with an air conditioner as a management target. The receiving terminal is connected to a plurality of wireless terminals and can perform data communication. FIG. 7 is a block diagram of an optimal control system according to the third embodiment of the present invention. The receiving terminal 160, the management target 172, and the management control device 165 are the same receiving terminal, management target, and management control device as those having the same reference numerals in FIG. The first wireless terminal 182, the second wireless terminal 183, the third wireless terminal 184, the fourth wireless terminal 185, the fifth wireless terminal 186, and the sixth wireless terminal 187 are the wireless terminals 149 described in FIG. In this state, there are a plurality of wireless terminals 149. The first wireless terminal 182, the second wireless terminal 183, the third wireless terminal 184, the fourth wireless terminal 185, and the fifth wireless terminal 186 are connected to the receiving terminal 160 so that data communication is possible. A dotted line indicates that the wireless communication is connected. Further, the sixth wireless terminal 187 cannot be connected to the receiving terminal 160 and cannot perform data communication. For example, it is conceivable that the communication distance is long after leaving the room and the radio cannot reach.

  At this time, each wireless terminal detects an acceleration corresponding to the user's action by the acceleration sensor 157, measures the pulse by the pulse sensor 158, and further measures the time by the timer 155. Further, the wireless communication means 159 detects whether communication with the receiving terminal 160 is possible. The motion amount per unit time is calculated by the motion amount calculation unit 151 from the detected acceleration value and time value, and the result is stored in the memory 156 in time series. For example, the motion amount can be obtained by integrating a value obtained by an acceleration sensor and a time measured by a timer to obtain a moving distance by integrating twice. The moving distance can be used as the amount of movement of the user. Further, personal information such as weight, gender, height, and age is stored in advance in the memory 156 as the user's personal information, and the calorie consumption calculation unit 152 calculates the calorie consumption of the person from the calculated operation amount and these personal information. Calculate and store in memory 156. At that time, the movement amount and the calorie consumption are stored in correspondence with each other. The calculation and storage are controlled by the control unit 150. When calculating the calorie consumption, if nothing is detected by the pulse sensor 158, it is assumed that the user is left unattached and the calorie consumption is zero.

  FIG. 8 is a diagram illustrating the state of each wireless terminal at a certain time in the optimal control system according to the third embodiment of the present invention. The wireless terminal column 188 represents the unique number of each wireless terminal. Within the communication area or column 189 indicates “Yes” when each wireless terminal can communicate with the receiving terminal, and “No” when the wireless terminal cannot communicate. The operation amount column 190 represents the operation amount of each wireless terminal at that time. The calorie amount column 191 represents the calorie amount at that time of each wireless terminal. For example, the wireless terminal with the unique number 1 can communicate with the receiving terminal, the operation amount at that time is 100, and the amount of calories consumed by the user is 100 kcal. In addition, since the wireless terminal with the unique number 4 has an operation amount of 0, it can be seen that there is only a calorie consumption amount for basal metabolism. The wireless terminal with the unique number 5 has a calorie consumption of 0, which is a state where the user has removed the wireless terminal.

  FIG. 9 is a diagram illustrating a state in a certain time zone of a wireless terminal having the optimum control system according to the third embodiment of the present invention. It is the figure which took the elapsed time on the horizontal axis, the operation amount, and whether or not wireless communication is possible on the vertical axis. The amount of movement is represented on the graph using a line 192. Whether or not communication is possible is represented on the graph using a line 193. The time T1 from the time t0 to the time t1, the time T2 from the time t1 to the time t4, and the time T3 from the time t4 to the time t5 are equal time, which is a predetermined unit time. For example, a predetermined value such as 1 minute is set in advance. . From time t0 to time t1, it is a time zone in which wireless communication is possible and the operation amount is always constant. At this time, the operation amount per unit time is obtained by integrating the line 192. At the time T2, the wireless communication is interrupted from the time t2 to the time t3, for example, when the user is out of the room. Within the wireless terminal, the operation amount may be calculated. At time T3, there is a case where the operation amount is 0, but the wireless communication is not interrupted.

  The operation of the optimum control system according to the third embodiment of the present invention will be described using a flowchart. FIG. 10 is a flowchart of the operation of the wireless terminal of the optimum control system according to the third embodiment of the present invention. FIG. 11 is a flowchart of the operation when the management control apparatus of the optimal control system according to the third embodiment of the present invention receives data. FIG. 12 is a flowchart of the operation of the management target of the optimal control system according to the third embodiment of the present invention. FIG. 13 is a diagram illustrating data of the wireless terminal stored in the storage unit to be managed by the optimum control system according to the third embodiment of the present invention. FIG. 14 is a diagram showing set values of the optimum control system according to the third embodiment of the present invention.

  The wireless terminal (182 to 187) calculates the operation amount every second using the measurement results of the acceleration sensor 157 and the timer 155 for each wireless terminal, and sets the time series based on the time data measured by the timer 155. Further, the operation amount value of the calculation result is stored in the memory 156 in association with the time data (step 1). Further, the calorie consumption per second is calculated using the movement amount and the personal information stored in the memory 156 in advance, and the calculated value is stored in the memory 156 corresponding to the value of the movement amount used. (Step 2). Personal information, time, operation amount, and calorie consumption are stored in the memory 156 in association with each other (step 3). In order to collect data every minute, the timer 155 measures one minute, determines whether one minute has passed, and if one minute has not passed, moves to step 1 and counts every second When one minute has passed, the process proceeds to a process of counting every minute (step 4).

  The movement amount and calorie consumption value for the past one minute for each personal information are added and stored in the memory 156 in time series as the movement amount and calorie consumption value for one minute (step 5). The wireless communication means 159 communicates with the receiving terminal 160, and transmits the personal information, the amount of movement for 1 minute corresponding to the personal information, and the calorie consumption value to the receiving terminal 160 (step 6). If the process is stopped as it is, the process ends (end). If the process is continued, the process proceeds to step 1. The stop of the process is determined by a predetermined number of times, time, input from the input means 154, or the like. In this way, data obtained by the wireless terminal is transmitted from the wireless terminal to the receiving terminal.

  Next, the receiving terminal 160 communicates data per minute sent from each wireless terminal with the management control device 165 via the network communication unit 163, the network 164, and the network communication unit 166, and the memory 170. The received data is stored for each personal information in time series using time data in the data (step 8). FIG. 13 shows the structure of data stored in the memory 170. The wireless terminal column 194 is a unique number of the wireless terminal. Here, it is a case where the unique number of the wireless terminal and the unique number of the personal information have a one-to-one correspondence. The time column 195 extracts and stores time data from the received data, and stores the amount of movement at that time in the amount-of-motion column 196 and the amount of consumed calories in the amount-of-calories column 197. For example, the operation amount at 10:10 of the wireless terminal 1 or personal information unique number 1 is 80, and the calorie consumption is 90 kcal.

  Next, the management control device 165 accumulates the data of the movement amount and the calorie consumption amount stored in the memory 170 for the past three minutes every minute. That is, the movement amount data and calorie consumption data for the past 3 minutes are stored in the memory 170 at the timing of every minute of all the receivable wireless terminals (step 9).

  Next, calculation for controlling the management target 173 is performed based on the integrated amount of data for the past 3 minutes every minute. The memory 170 stores in advance setting data for determining how to control the management target 172. FIG. 14 is a diagram showing the configuration of the setting data. The operation amount column 198 stores a range of operation amounts. The air volume column 199 stores an air volume setting value corresponding to the range of the operation volume. The temperature column 200 stores a set value of temperature corresponding to the operating amount range. The wind direction column 201 stores the setting value of the wind direction corresponding to the range of the operation amount. For example, when the operation amount is in the range of 0 to 100, the airflow setting value is one step, the temperature setting value is plus or minus 0 degrees, that is, not changed, and the airflow setting value is stored as an upward setting value. ing. An operation range that matches the value of the operation amount for the past 3 minutes is obtained, and further, the values of the air amount, temperature, and wind direction are obtained (step 10).

  The management control device 165 and the management target 172 communicate with each other using the communication unit 168 and the communication unit 171, and the management control device 165 transmits the data of the obtained air volume, temperature, and wind direction values to the management target 172. Based on the received data, the control unit 173 of the management target 172 performs control to set the air volume value received by the blower 179 and control to set the temperature value received by the heating / cooling device 180 to change the wind direction variable machine 181. Is controlled to be the value of the received wind direction (step 11).

  As another form, new data set by the display means 174 is displayed. It is also possible to incorporate the function of the management control device 165 into the management target 172. By connecting the communication unit 171 to the network 164 and storing in the storage unit 177 the same program setting value as the control program, setting value, etc. performed by the management control device 165, the same function can be achieved.

  Further, although one receiving terminal has been described, it is possible to have a plurality of receiving terminals. At that time, the management control device 165 can detect which receiving terminal and which wireless terminal are connected, and can control each receiving terminal.

  Furthermore, it is possible to measure the strength of radio waves from the wireless terminal received by the receiving terminal and control the management device based on the measured value. As setting values, the strength of radio waves is divided into a plurality of ranges, and the corresponding wind direction, air volume, and temperature values are stored in advance. For example, when more than half of the people have weak radio waves, control is performed by setting the wind direction downward, setting the air volume to three steps, and further setting the temperature to −1 degree. Then, even if many people are at distant locations, it is possible to increase the air volume in order to increase the air volume reaching there, or to control the temperature further lower.

  Further, instead of the operation amount, the management target can be controlled based on the operation result calculated based on the operation amount and the personal information, for example, the calorie consumption.

  Next, an optimal control system according to a fourth embodiment of the present invention will be described. The fourth embodiment of the present invention is a system that optimally controls a plurality of elevators. This will be described with reference to FIGS. 15 and 16. FIG. 15 is a block diagram of management targets of the optimal control system according to the fourth embodiment of the present invention. FIG. 16 is an operation flowchart of the optimum control system according to the fourth embodiment of the present invention.

  The first elevator 205 and the second elevator 206 are elevators. The first elevator 205 and the second elevator 206 are collectively referred to as a management device 204. The first elevator 205 and the second elevator 206 are controlled by the management control device 203. The management control device 203 is a control device having the functions of the receiving terminal 160, the management control device 165, and the management target 172 of the optimal control system according to the third embodiment. The same is true in that data is received from the wireless terminal and stored in time series. The total amount of operation for a predetermined time, for example, the past 3 minutes, is calculated for each wireless terminal from the data received and stored from the wireless terminal (step 12). Compare the total operation amount of each wireless terminal with a preset value, and if the operation amount is less than or equal to the predetermined value, determine that the terminal is waiting for an elevator and exceed the predetermined value. Judge that it is not waiting for the elevator. The management control device 203 determines the receiving terminal that is communicating with the wireless terminal, and the management control device 203 counts the number of wireless terminals that are determined to be waiting for the elevator that each receiving terminal is communicating with (step 13). When the number of wireless terminals is the largest, the management control apparatus 203 performs control to move the elevator with priority to a place where the receiving terminal is located (step 14).

  A person in the building is equipped with a wireless terminal, a receiving terminal is installed in the elevator hall on each floor of the building, and the number of people in the vicinity of the elevator hall and its operation are detected. In the case of a person who has a certain amount of movement and stays in the vicinity of the elevator hall for a long time, it can be assumed that he / she stays in the elevator hall for some reason but does not intend to ride the elevator. Since it is determined that a person who stays for a long time and has a certain amount of motion does not intend to ride the elevator, the value of this motion amount is stored in advance in the management control device 203 as a threshold value. As described above, the movement amount and time of the target having the wireless terminal are measured, the measured data is transmitted to the management control device 203 by wireless, and the predetermined value as the threshold value stored in advance in the management control device 203 is received. By controlling the management target based on the data, the management target can be optimally controlled.
