In step S22, the information transmission unit 23 transmits the occupancy information to another relay station 2 or the master station 3 according to the instruction of the control unit 22.

FIG. 6 is a flowchart showing an example of the operation of the master station 3.

In step S31, the control unit 32 determines whether or not the information receiving unit 31 has received the occupancy information from the slave station 1 or the relay station 2. When the occupancy information is received, the process proceeds to step S32. On the other hand, if the occupancy information has not been received, the process of step S31 is repeated until the occupancy information is received. In step S32, the information transmission unit 33 transmits the occupancy information to the sequencer 4 according to the instruction of the control unit 32.

FIG. 7 is a flowchart showing an example of the operation of the sequencer.

In step S41, the control unit 42 determines whether or not the serial communication unit 41 has received the occupancy information from the master station 3. When the occupancy information is received, the process proceeds to step S42. On the other hand, if the occupancy information is not received, the process proceeds to step S44.

In step S42, the control unit 42 stores the occupancy information in the occupancy information storage unit 43. In step S43, the control unit 42 transmits the occupancy information to the equipment reservation device 5 via the LAN communication unit 44.

In step S44, the control unit 42 determines whether or not there is a request from the equipment reservation device 5 to transmit the occupancy information. Examples of the occupancy information required by the equipment reservation device 5 include the past occupancy information described above. If there is a request, the process proceeds to step S45. On the other hand, if there is no request, the process returns to step S41.

In step S45, the control unit 42 acquires the occupancy information requested by the equipment reservation device 5 from the occupancy information storage unit 43. In step S46, the occupancy information is transmitted to the equipment reservation device 5 via the LAN communication unit 44.

From the above, according to the first embodiment, by installing the slave station 1 having the motion sensor 11 under the desk 6, the usage status of each desk 6 can be determined from the detection result of the motion sensor 11. It can be easily grasped. Further, when one desk 6 is installed in one conference room, the usage status of the conference room can be easily grasped from the detection result of the motion sensor 11. Therefore, a person who intends to use the desk 6 or the conference room is present in the display unit 52 of the equipment reservation device 5 without going directly to the place where the desk 6 is installed or the conference room to check the usage status. You can check the information. With such a configuration, the device for inputting the start or end of use of the conference room, which was installed at the entrance of the conference room in the conventional system, becomes unnecessary, and the usage status management system can be constructed at a lower cost than before. can do. Further, since the device is not required, it is possible to prevent the user from leaking the operation, which improves convenience.

For example, when a plurality of desks are installed in a small conference room and a motion sensor 11 is installed on the wall or ceiling of the conference room, even if there is a desk that is not in use, if the next desk is in use, a person From the detection result of the motion sensor 11, it is determined that the entire conference room is in use. In the conventional system, since it is applied to a conference room with a partition, it cannot be applied when a part of the conference room is used for a limited time such as an event or a conference using an empty space. On the other hand, according to the usage status management system of the first embodiment, since the usage status can be grasped for each desk 6, it is possible to flexibly respond to the layout change. For example, in a meeting space in which only desks are arranged using an open space, the usage status of the meeting space can be accurately grasped, which improves convenience. As described above, in the usage status management system of the first embodiment, since the detection range of the motion sensor 11 installed under the desk 6 is only about the size of the desk, it can be used not only in the conference room but also in an open space. It can also be applied to places where only desks are placed.

The usage status management system of the first embodiment can be used in a Wi-Fi (registered trademark) environment within a certain range in which radio waves can reach. On the other hand, in a Wi-Fi environment, use is restricted within the reach of radio waves. As a countermeasure against such a problem, the usage status management system according to the first embodiment is configured to be applicable even in an environment where the environment for performing Wi-Fi communication is not prepared. Specifically, in the usage status management system according to the first embodiment, since the slave station 1, the relay station 2, and the master station 3 are specific low power radios, the slave station can be used by using the multi-hopping function. Information can be transmitted between 1 station or between the slave station 1 and the relay station 2, and can be easily expanded without limiting the range of use.

For example, when a slave station equipped with a motion sensor is installed on the wall or ceiling of a conference room, its use is limited to the space as a permanent conference room. On the other hand, in the usage status management system according to the first embodiment, by driving the slave station 1 installed on the desk 6 with a battery, wiring becomes unnecessary, and it can be applied not only to a permanent conference room but also to various uses. Can be done. For example, it can be applied to an event venue that is temporarily used, a meeting space that uses an open space, or a space where only a desk for business negotiations is installed. Further, since the slave station 1 provided with the motion sensor 11 is installed under the desk 6, it is possible to flexibly support various uses simply by moving the desk 6.

In the above description, the case where the slave station 1 is provided with the motion sensor 11 has been described, but the present invention is not limited to this. For example, it can be appropriately changed according to the application such as a temperature sensor.

The reservation information is associated with each desk 6, and includes at least the start time of use of the desk 6, the end time of use, the name of the person making the reservation, and the like. The reservation canceling unit 53 cancels the use of the desk reserved by the reservation person based on the reservation information stored in the reservation information storage unit 54 and the usage status of the desk 6.

<Operation>
FIG. 9 is a flowchart showing an example of the operation of the reservation canceling unit 53.

In step S51, the reservation canceling unit 53 determines whether or not the desk 6 is reserved based on the reservation information stored in the reservation information storage unit 54. If the desk 6 is reserved, the process proceeds to step S52. On the other hand, if the desk 6 is not reserved, the process of step S51 is repeated.

In step S52, the reservation canceling unit 53 determines whether or not the desk 6 is in use based on the occupancy information received from the sequencer 4 by the information processing unit 51. If the desk 6 is in use, the process returns to step S51. On the other hand, if the desk 6 is not in use, the process proceeds to step S53.

In step S53, the reservation canceling unit 53 determines whether or not a predetermined time has elapsed from the usage start time of the reserved desk 6 based on the reservation information stored in the reservation information storage unit 54. The time elapsed from the start time of use can be arbitrarily set. If a predetermined time has elapsed from the start time of use, the process proceeds to step S54. On the other hand, if a predetermined time has not elapsed from the start time of use, the process returns to step S51.

In step S54, the reservation canceling unit 53 cancels the reservation of the desk 6. That is, the reservation canceling unit 53 makes a reservation when the user of the desk 6 who is the reservation person does not exist within the detection range of the motion sensor 11 by the time when a predetermined time elapses from the reserved use start time. To cancel.

From the above, according to the second embodiment, by providing the reservation canceling unit 53, the reservation is automatically canceled when the situation where the desk is not used even though the reservation is made continues. Therefore, the desk 6 can be effectively used. Further, when one desk 6 is installed in one conference room, the reservation can be canceled for each conference room.

In the above description, the case of automatically canceling when a predetermined time has elapsed from the reserved start time of use has been described, but the present invention is not limited to this. For example, the reservation cancellation unit 53 may cancel the reservation when the use of the desk 6 is completed earlier than planned. That is, the reservation canceling unit 53 no longer exists within the detection range of the motion sensor 11 before the end time of use reserved by the user of the desk 6 who is the reservation person who was within the detection range of the motion sensor 11. You may cancel the reservation at that time. By performing such a process, the desk 6 can be effectively used.

<Embodiment 3>
<Structure>
FIG. 10 is a block diagram showing an example of the configuration of the usage status management system according to the third embodiment of the present invention. As shown in FIG. 10, the usage status management system according to the third embodiment is characterized in that the equipment reservation device 5 includes a usage record management unit 55. Since other configurations and operations are the same as those in the second embodiment, detailed description thereof will be omitted here.

The usage record management unit 55 manages the usage record of the desk when the reservation person who has reserved the use of the desk 6 has made a reservation in the past. FIG. 11 is a block diagram showing an example of the configuration of the usage record management unit 55. As shown in FIG. 11, the usage record management unit 55 includes a reservation person information storage unit 551, a control unit 552, and a reservation status monitoring unit 553.

The reservation person information storage unit 551 is composed of a storage medium such as a hard disk or a semiconductor memory, and stores the usage record at the time of making a reservation in the past for each reservation person who has reserved the use of the desk 6 as the reservation person information. ing. The reservation person information includes information such as the number of times the reservation person has reserved the use of the desk 6 and the number of times the reservation has been canceled by the reservation cancellation unit 53. The reservation status monitoring unit 553 monitors whether or not the reservation has been canceled by the reservation cancellation unit 53.

<Operation>
FIG. 12 is a flowchart showing an example of the operation of the usage record management unit 55.

In step S61, the reservation status monitoring unit 553 determines whether or not the reservation has been canceled by the reservation canceling unit 53. If the reservation has been canceled, the process proceeds to step S62. On the other hand, if the reservation has not been canceled, the process of step S61 is repeated.

In step S62, the reservation status monitoring unit 553 acquires the information of the reservation person whose reservation has been canceled by the reservation cancellation unit 53 from the reservation cancellation unit 53. The information acquired by the reservation status monitoring unit 553 at this time includes at least the name of the reservation person included in the reservation information stored in the reservation information storage unit 54.

In step S63, the control unit 552 stores the reservation person information acquired by the reservation status monitoring unit 553 in the reservation person information storage unit 551 as the reservation person information. In the reservation person information storage unit 551, at least the number of times the reservation person has reserved the use of the desk 6 and the number of times the reservation has been canceled are counted up by one for the target reservation person.

In step S64, the control unit 552 determines whether or not the unused rate of the desk 6 by the reservation person is high. Specifically, the control unit 552 uses the reservation person information stored in the reservation person information storage unit 551 to obtain the ratio of the number of times the reservation is canceled to the number of times the reservation is made. The threshold value can be set arbitrarily. Then, the control unit 552 determines that the unused rate is high when the ratio of the number of times the reservation is canceled exceeds a predetermined threshold value, and sets the ratio of the number of times the reservation is canceled to a predetermined threshold value. If it does not exceed, it is judged that the unused rate is low. If the unused rate is high, the process proceeds to step S65. On the other hand, if the unused rate is low, the process returns to step S61.

In step S65, when the target reservation person makes another reservation other than the reservation canceled by the reservation cancellation unit 53, the control unit 552 cancels the other reservation.

From the above, according to the third embodiment, the desk 6 can be automatically canceled in consideration of the past usage record by providing the usage record management unit 55. It can be used effectively. Further, when one desk 6 is installed in one conference room, the reservation can be automatically canceled for each conference room.

In step S64 of FIG. 12, the case where the control unit 552 obtains the ratio of the number of times the reservation is canceled to the number of times the reservation is made has been described, but the present invention is not limited to this. For example, the control unit 552 may determine that the unused rate is high when the number of times the reservation is canceled exceeds a predetermined number of times. In this case, the control unit 552 determines that the unused rate is low when the number of times the reservation is canceled does not exceed the predetermined number of times.

In FIG. 12, the time from the determination that the reservation has been canceled in step S61 to the cancellation of another reservation in step S65 may be arbitrarily set.

In the above, the case where the reservation is automatically canceled in consideration of the past usage record has been described, but the present invention is not limited to this. For example, in step S65 of FIG. 12, the display unit 52 indicates that there is a high possibility that the desk 6 or the conference room related to the other reservation will not be used without canceling the other reservation of the target reservation person. May be good.
