Description

  The present invention relates to a user location confirmation system, and more particularly, to a system for detecting an entrance / exit state of a user who uses an accommodation facility.

  Conventionally, when checking in to a hotel or other accommodation facility, the customer tells the reception staff whether there is a reservation or the desired guest room, and then searches the guest room at the front desk according to the customer's request. After that, it was mainstream to go through the procedure of handing over the guest room key to the customer. For this reason, it is indispensable to assign a staff member who specializes in front work at the accommodation facilities. Especially in large accommodation facilities, it is necessary to secure a large number of front staff members, and this is one of the factors leading to a rise in personnel costs. It was one.

  Thus, for example, Patent Document 1 proposes a hotel check-in device that automates check-in processing by installing an automatic reception device at the front desk or the entrance of an accommodation facility to reduce the number of front staff. The check-in device includes a touch panel display device (input terminal) and a host device that performs a key issuance process, an empty room information update process, and the like according to information input to the display apparatus.

  When a user inputs necessary information to the display device, the check-in device searches the host device for a suitable room from the vacant rooms, and identifies information assigned to the key of the guest room and the display device. The input user information is associated and recorded in a memory, and then the guest room key is delivered to the user.

JP 2000-113046 A

  According to the check-in apparatus, since the ratio of human work in the check-in process can be reduced, the number of front staff can be reduced, and the labor cost can be reduced. In addition, since the identification information of the key to be issued and the information of the customer are recorded in association with each other at the time of check-in, it is possible to manage which user is staying in which room.

  However, in the above check-in device, it is only possible to determine which user starts to use which guest room, so it is possible to know whether the user is in the guest room. Can not. Preparation of bedding and cleaning of guest rooms is preferably performed while the user leaves the room, and in accommodation facilities that provide in-room meal services, the user should be prepared to prepare food when they are in the room. In addition, it is extremely useful information whether or not the user is in the room, and it is desired to construct a system that can easily grasp the presence or absence of the room.

  In addition, although it is a magical act, there has also been a situation in which an employee of an accommodation facility falsifies user information and vacant room information and illegally stays. If it becomes addictive in many cases, it will have a great impact on the occupancy rate and sales of guest rooms, so immediate measures are being urged.

  However, in the system that checks the user and the guest room (key) at the time of check-in, such as the above check-in device, if the fraud is not detected even at the time of check-in, the employee can use the guest room relatively easily. Because it can, it is not suitable for preventing such acts. In addition, some of the accommodation facilities still perform check-in work in the face-to-face with the front clerk and the user as before, and it is easier to cheat at such facilities. For this reason, there is a strong demand for the construction of a system that can detect the use state of a guest room at any timing, not temporarily at the time of check-in.

And a wireless LAN receiving unit 54 that outputs to the unit 46.

  Next, the operation of the location confirmation system 1 having the above configuration will be described. In order to facilitate understanding of the operation, first, a method for detecting the user's entering / exiting state of the guest room as a basic operation of the location checking system 1 will be described with reference to FIGS.

  In detecting the entering / exiting state, as shown in FIG. 5, first, key information (identification information) of a key to be used is recorded in the guest room database 47b (see FIG. 4) of the management PC 47 in association with the guest room information. Then, key registration processing is performed (step S1). Next, information (for example, name) of the user who uses the key is recorded in the user database 47c in association with the key information of the key to be used, and user registration processing is performed (steps S2 and S3). ).

  Next, a radio signal (key information) is transmitted intermittently (for example, every 2 to 5 s) in the key information transmission unit 22 (see FIG. 2) attached to the key (step S4). The transmission timing of the radio signal at this time is controlled by the time counted by the timer 22c (see FIG. 3) in the key information transmission unit 22. For this reason, the radio signal from the key information transmission part 22 is transmitted only according to time passage, without depending on a user's action. The radio signal does not necessarily need to be transmitted intermittently, and may be transmitted continuously (always during the key usage period).

  In the above state, as shown in FIG. 6, the user enters the guest room, and the key information receiving unit 31 (see FIG. 1) in the guest room is within the communication area of the key information transmitting unit 22 (the area where the radio signal reaches). As shown in FIG. 5, the key information receiving unit 31 receives a radio signal from the key information transmitting unit 22 (step S5: Yes).

  Next, the key information receiving unit 31 generates key information and radio wave intensity information (decibel value) from the received radio signal, adds room information to the information, and outputs the information to the power line transmission unit 32. The guest room information added by the key information receiving unit 31 is not necessarily information indicating the guest room, such as a guest room number, and may be identification information for identifying the key information receiving unit 31. However, in this case, the guest room where the key information receiving unit 31 is installed and the identification information of the key information receiving unit 31 need to be recorded in association with each other and stored in the management PC 47 as a database.

  Next, in the power line transmission unit 32, the key information, the radio wave intensity information, and the guest room information are output to the power line 33 and transmitted to the power line reception unit 51. Thereafter, the key information and the like are transmitted to the data collection processing unit 46 via the wireless LAN transmission unit 52, the repeater 53, and the wireless LAN reception unit 54 (see FIG. 1) and transmitted to the management PC 47 (step S6). .

  Next, in the management PC 47, the transmitted key information and the like are collated with the guest room database 47b and the user database 47c (step S7). Then, after identifying the user (user of the key) from the key information, it is identified which room the identified user is in based on the room information. When these specific processes are completed, it is determined that the user is in the room (step S8), and a mark or the like indicating that the user is in the room is displayed on the display 47e (see FIG. 4).

  The information transmitted to the management PC 47 includes radio wave intensity information. This radio wave intensity information can be used to more accurately specify whether or not the user is inside the cabin. That is, the reception intensity of the radio signal becomes stronger as the communication distance becomes shorter, and therefore corresponds to the distance between the transmitter and the receiver. For this reason, in the management PC 47, the radio wave intensity that can be detected only when communicating in the guest room is set as a determination reference value, and the radio wave intensity detected during actual use is compared with the determination reference value, so that the user Can be identified in the cabin or only in the vicinity of the cabin.

  Judgment standard values need to be set appropriately for each guest room in consideration of the room layout. For example, in the case of a room with a simple square layout, a radio signal is transmitted from the vicinity of the entrance in the guest room. It can be set to the radio field strength obtained at the time.

  Next, in the management PC 47, the time information generated by the timer 47a (see FIG. 4) and the remaining stay period are added to the user information and usage status (room entry, occupancy), and then the usage status database 47d. Record and update the recorded contents of the usage status database 47d (step S9).

  On the other hand, when the user does not enter the guest room, the radio information cannot be received by the key information receiving unit 31 in the guest room (step S5: No), so no information is given to the management PC 47. Not transmitted. In this case, the management PC 47 determines that the user is not in the cabin (step S10), and records the determination result in the usage status database 47d (step S9).

  Next, the operation of the location confirmation system 1 will be described along a series of flow from check-in to check-out with reference to FIGS.

  In the check-in process, as shown in FIG. 7, first, a user information input process is executed (step S11). The user information may be input by presenting an entry sheet or the like to the user, filling in necessary items, and inputting the contents into the management PC 47 by the front staff, or the above-mentioned JP-A-2000-2000. As in the check-in device described in Japanese Patent No. 113046, a touch panel display device may be installed and performed by a user's touch input.

  Next, the guest room to be accommodated is determined according to the contents desired by the user (step S12), and the key of the guest room is taken out from the key storage shelf 44 (see FIG. 1). At this time, the key information reading unit 45 detects the key (key information transmission unit 22) whose radio field intensity has been weakened, and outputs the key information of the key to the data collection processing unit 46. Then, in the management PC 47, the key taken out from the key storage shelf 44 is specified based on the key information, and the delivery of the key is detected (step S13).

  Next, the key information is read by holding the extracted key over the check-in pad 42 (see FIG. 8) and output to the management PC 47 via the data collection processing unit 46. In response to receiving the key information read by the check-in pad 42, the management PC 47 approves the key lending (step S14), the user information input in step S11, and the step S13. The read key information is recorded in the user database 47c (step S15).

  Next, the key is delivered to the user and an accounting process is performed as necessary. When the user who received the key enters the guest room, the user's entry is detected by the above-described detection method (step S16), and the key transmitted from the key information receiving unit 31 in the guest room in the management PC 47 is detected. The information and the like are collated with the recorded contents of the user database 47c (step S17). As a result, the user who has accepted the accommodation confirms whether the user has correctly entered the guest room arranged by the accommodation facility, and then the management PC 47 indicates that the user has entered the room and the time at that time. The information is recorded in the usage status database 47d (step S18), and the check-in process is terminated.

  After that, during the staying period, the state of entering, staying in, and leaving the room is detected by the detection method described above, and whenever changes are recognized, the time of use and the remaining staying period are used. Record in database 47d. At that time, based on the key information transmitted from the key information receiving unit 31 in the guest room, the person who has entered the room is also specified and recorded together in the usage status database 47d.

  In addition, the key information transmission unit 22 records the stay period in the memory 22a, and the control unit 22d manages the remaining stay period. When the stay period expires or the stay period of the user exceeds the stay period. Sometimes it may be notified by light or voice. These processes may be performed by the key information receiving unit 31.

  Then, when the checkout process is performed after the stay period has expired, as shown in FIG. 9, the user or the front clerk holds the key over the checkout pad 43 (see FIG. 1), so that the checkout pad 43 To read the key information (step S21).

  Next, in response to receiving the key information read by the checkout pad 43, the management PC 47 starts the checkout process for the guest room corresponding to the key (step S22). At that time, if there is an additional charge, it is displayed on the display unit 47e (see FIG. 4) of the management PC 47, and there is a record that a person other than the user of the key has entered the room. Is also displayed on the display unit 47e.

  After that, when the front clerk stores the key in the storage shelf 44 (see FIG. 1), the key information reading unit 45 outputs the key information of the key whose radio field intensity has increased to the data collection processing unit 46, and the management PC 47 , It is detected that the key has been accommodated (step S23). Next, the management PC 47 records the checkout in each database such as the guest room database 47b, the user database 47c, and the usage status database 47d (step S24), and the checkout process is terminated.

  As described above, according to the present embodiment, the key information transmitting unit 22 that transmits the key information by the radio signal is attached to the key, and the key information receiving unit 31 that receives the radio signal is installed in the guest room, In order to determine whether or not a user has entered a room according to whether or not the key information receiving unit 31 has received key information from the key information transmitting unit 22, it is easy to grasp the user's entry / exit state. It is also possible to identify who (which key) has entered the room. For this reason, it is possible to grasp whether or not the user is in the room and who is present, and to improve the service if such information is effectively used in various services at the accommodation facility. Is possible.

  In addition, regarding fraudulent acts by employees, in this embodiment, since it is possible to grasp the entrance / exit status not only at the time of check-in but also throughout the accommodation period (period in which the guest room can be used), It becomes easier to find the act and it becomes possible to lead to the suppression of the fraud. As an employee countermeasure, instead of attaching the key information transmission unit 22 to the key, a measure such as embedding a small transmitter that transmits identification information in a jewelry such as a nameplate (badge) or uniform. Good. According to this, since the behavior can be monitored even if the employee does not have the key, it is possible to more effectively suppress the fraud.

  Furthermore, according to the present embodiment, since the time information is added to the entry / exit state determined by the management PC 47 and the usage status database 47d is recorded for each guest room, the entry / exit state for each guest room is provided. The recorded person and the time at that time can be recorded. For this reason, if these records are used as data for measuring the trends of users who have stayed at lodging facilities, they can be used as useful research data. It can be used as material for detection.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the invention described in the claims.

  For example, in the above embodiment, when the radio signal transmitted from the key information transmitting unit 22 is received by the key information receiving unit 31, two types of identification information of key information and room information are transmitted to the management PC 47. However, a set of identification information is allocated to the key information transmitting unit 22 and the key information receiving unit 31 corresponding to the same guest room (for example, the identification information allocated to the key information transmitting unit 22 for the room 302 and the room 302). When the key information receiving unit 31 receives a radio signal indicating identification information paired with its own identification information, the radio signal is transmitted to the key information receiving unit 31 installed in the key information receiving unit 31. You may make it transmit the signal which shows that it received to the management PC47.

  Further, in the above embodiment, the management PC 47 determines the user entry / exit state, but the discrimination unit for determining the user entry / exit state to the guest room based on the output from the key information receiving device 3 is provided for each floor. It is also possible to install them every time (for example, between the power line receiving unit 51 and the wireless LAN transmitting unit 52), and to collect the determination results derived by the determining units on each floor into the management PC 47.

  Furthermore, in the above embodiment, the output of the key information receiving unit 31 is transmitted to the wireless LAN transmission unit 52 using power line communication and then transmitted to the management PC 47 using wireless communication. 32 and the power line receiving unit 51 may be installed in a wireless communication device, and communication between the key information receiving unit 31 and the management PC 47 may be unified by wireless communication.

  Moreover, in said embodiment, although the key information receiving part 31 is installed only in a guest room, you may install the key information receiving part 31 in and out of a guest room. According to this, although the number of installed key information receiving units 31 increases, it becomes possible to more accurately determine the location of the user. For example, even if the key information receiving unit 31 installed in the guest room breaks down, it is possible to grasp the user's entry / exit state from the presence / absence of the radio signal and the radio wave intensity at the key information receiving unit 31 installed outside the guest room. It is also possible to take measures against failure.

  Further, in the above-described embodiment, the wireless LAN transmission unit 52 and the wireless LAN reception unit 54 are provided, and key information received by the power line reception unit 51 is transmitted to the data processing device 4 by wireless communication. However, wired communication is used. Or may be transmitted using both wireless communication and wired communication.
