Description

The present invention relates to a key telephone system, a key telephone device, and a method and program for outputting evacuation guidance messages.

There is an on-site telephone system that can effectively utilize the functions of the on-site telephone system, such as constant connection, operation during power outages, and visible and audible displays, to notify users of emergency information by voice and guide them to evacuation routes without installing a dedicated information display device, etc. (see, for example, Patent Document 1).

JP 2008-42320 A

The following analysis is provided by the present invention.

The technology disclosed in Patent Document 1 stores unique evacuation route information for each telephone in advance, and in the event of an emergency, the telephone provides voice guidance on that evacuation route information. For example, in facilities such as hotels where multiple evacuation routes are available, the optimal evacuation route differs for each guest room. In such a situation, the technology disclosed in Patent Document 1 makes it possible to provide evacuation route guidance appropriate for each individual guest room to telephones installed in each guest room.

However, in a hotel or the like, not all guest rooms are necessarily occupied by guests. Therefore, the technology disclosed in Patent Document 1 is wasteful. For example, if the volume of the voice guidance is too loud, the guests may also hear the voice guidance output from telephone terminals in rooms where there are no guests or telephone terminals in hallways where there are no people around, which may confuse the guests.

The present invention was made in consideration of the above circumstances, and aims to provide technology that provides sufficient evacuation guidance messages efficiently and without waste, thereby contributing to improving safety.

<<First embodiment>>
In this embodiment, in a facility where it is necessary to notify an unspecified number of temporary residents of the optimal evacuation route from among multiple evacuation routes, a system using a key telephone device (key telephone system) is used to notify each individual resident of the optimal evacuation route. Details of this embodiment will be described below by taking as an example a case where the key telephone system of this embodiment is used in a hotel.

First, the overall configuration of the key telephone system 100 of this embodiment will be described. FIG. 1 is a diagram showing the overall configuration of the key telephone system 100 of this embodiment. As shown in this figure, the key telephone system 100 of this embodiment includes a key telephone device 200, a key telephone (telephone terminal) 300, and a wireless IP terminal 400.

The number of telephone terminals 300 and wireless IP terminals 400 is not important. The telephone terminals 300 are placed in various places in the hotel, such as the front desk, each guest room, the lobby, the elevator hall, the banquet hall, the restaurant, etc. Basically, all employees and guests of the hotel are provided with a wireless IP terminal 400.

Each telephone terminal 300 is accommodated in a key telephone device 200. In addition, the wireless IP terminal 400 connects to an IP network 900 such as a LAN (local area network) via the nearest wireless base station (access point (AP) 500). In addition, the key telephone device 200 is also connected to the LAN 900.

In the following, telephone terminals 300 will be described by distinguishing between guest room terminals 310 and front desk terminals 320 as necessary. The front desk terminals 320 are terminals that are placed at the front desk of a hotel, etc., and are also used as input/output devices for the key telephone device 200. The guest room terminals 310 are a general term for telephone terminals 300 that are placed in guest rooms, corridors, etc., other than the front desk terminals 320. All are placed in approximately fixed positions.

The key telephone device 200 is the main device of a key telephone system with an IP network connection function. In this embodiment, it is connected to the access point 500 via the IP network 900. The access point 500 is connected to the wireless IP terminal 400 by wireless connection. In this embodiment, the wireless IP terminal 400 is accommodated in the key telephone device 200 via the access point 500 and is assigned an extension number.

The access points 500 are assigned numbers, such as IP addresses, that do not overlap with other access points. In this embodiment, the access points are placed, for example, in each hotel guest room, restaurant, banquet hall, lobby, around the front desk, elevator hall, etc. In this embodiment, as described below, the access points are used to identify the placement position of the telephone terminal 300, so it is desirable to place them, for example, in the vicinity of the telephone terminal 300.

The wireless IP terminal 400 can connect to the key telephone device 200 via any of the access points 500 installed in the hotel. The wireless IP terminal 400 measures the radio wave strength of the access points 500 and determines the access point 500 with the strongest radio wave strength as the nearest access point 500. The wireless IP terminal 400 then operates to connect to the nearest access point 500.

The wireless IP terminal 400 is, for example, a portable information processing device (wireless terminal) with a wireless communication function, such as a smartphone. A dedicated terminal may be prepared as the wireless IP terminal 400. The wireless IP terminal 400 may also be realized by installing a dedicated application on a general-purpose portable information processing device. In the following, this embodiment will be described using an example in which the wireless IP terminal 400 is realized by installing a dedicated application on a general-purpose smartphone.

The key telephone device 200 also accommodates the guest room terminal 310 and the front desk terminal 320 via an IP network or digital connection. The guest room terminal 310 and the front desk terminal 320 are assigned extension numbers. The guest room terminal 310 and the front desk terminal 320 can play back audio and other messages from the key telephone device 200 without responding.

Here, the details of the key telephone device 200 will be described. FIG. 2(a) is a functional block diagram of the functions of the key telephone device 200 of this embodiment related to the processing of this embodiment.

As shown in this figure, the key telephone device 200 of this embodiment includes an information management unit 210, a location acquisition unit 220, a message sending unit 230, and a memory unit 260.

The memory unit 260 has a message table 261 and a wireless IP terminal table 262, and updates these tables by adding, deleting, etc. according to instructions from each unit.

The message table 261 stores the extension number of the telephone terminal 300, the evacuation guidance message, and the location of the access point 500 in association with the IP address of the access point 500. A specific example of the message table 261 is shown in FIG. 3.

As shown in this figure, the message table 261 of this embodiment includes, for each access point 500, an access point IP address 261a, a telephone terminal extension number 261b, an evacuation guidance message, an access point installation location 261e, and a called guest name 261f. The evacuation guidance message registered includes an evacuation guidance message 261c for guests and an evacuation guidance message 261d for employees.

For example, if the access point 500 is located in a guest room, the extension number of the guest room terminal 310 in the same guest room is registered as the telephone terminal extension number 261b. If the access point 500 is located outside the guest room, such as in a hallway, the extension number of the telephone terminal 300 located closest in distance is registered.

The evacuation guidance message 261c for guests and the evacuation guidance message 261d for employees are templates for voice messages. As described below, the voice message to be output is created in combination with the user name obtained from the wireless IP terminal table 262. Note that if the guest room terminal 310 has a display function, it may also be a display message.

In addition, two types of evacuation guidance messages 261d for employees are registered depending on whether or not the name of the guest on call 261f, which will be described later, is included. Hereinafter, the message used when the name of the guest on call 261f is registered will be referred to as a "registered message," and the message used when the name is not registered will be referred to as an "absent message." The registered message may include, for example, information regarding the corresponding access point installation location 261e.

Similarly, for the access point installation location 261e, if the access point 500 is installed in a guest room, the guest room number is registered. If the access point 500 is installed outside the guest room, such as in a hallway, the characteristics of the installation location, or the characteristics of the installation location of the telephone terminal 300 that is located closest in distance, are registered. For example, if the access point 500 is installed at the southern end of the hallway on the 5th floor, it is registered as "south end of the hallway on the 5th floor," and if the access point 500 is installed in the hallway near room 3302, it is registered as "hallway near room 3302," etc.

The called guest name 261f is registered when an evacuation guidance message 261c for the guest is output to the corresponding telephone terminal 300. Details will be described later.

The wireless IP terminal table 262 is a table that stores, for each wireless IP terminal 400 currently accommodated by the key telephone device 200, the extension number assigned to that terminal, the name of the user, and the user's classification (attributes), in association with each other. An example is shown in FIG. 4.

As shown in this figure, the wireless IP terminal table 262 registers the user name 262b and user category 262c of the wireless IP terminal 400 for each extension number (wireless IP extension number) 262a assigned to the wireless IP terminal. In this embodiment, the user category 262c is either a guest or an employee. However, the category is not limited to this. Depending on the category, a different evacuation guidance message is prepared in the message table 261.

As described below, for guests, these are registered at check-in and deleted at check-out. For employees, they are registered and deleted as appropriate. Note that only unique values are accepted for the wireless IP extension number 262a.

The information management unit 210 manages the information stored in the storage unit 260. In this embodiment, it manages a message table 261 and a wireless IP terminal table 262. In this embodiment, the information management unit 210 instructs the storage unit 260 to register information in these tables or delete information from the tables according to instructions from the user.

In this embodiment, the front terminal 320 is used as an input/output device for the key telephone device 200. That is, a user (e.g., a front desk clerk) instructs, via the front terminal 320, information to be registered in the message table 261 and/or information to be registered in the wireless IP terminal table 262.

For example, if the key telephone device 200 is equipped with input/output devices, registration may be performed using these.

The location acquisition unit 220 performs location acquisition processing to acquire location information of each wireless IP terminal 400 currently accommodated by the key telephone device 200. In this embodiment, the installation location of the access point 500 used by each wireless IP terminal 400 is acquired as the location of that wireless IP terminal 400. Note that in this embodiment, the location acquisition unit 220 executes location acquisition processing at a predetermined time interval when an emergency occurs.

When an emergency occurs (emergency), the message sending unit 230 sends an evacuation guidance message to guests and employees carrying wireless IP terminals 400. In this embodiment, when a wireless IP terminal 400 carried by a guest is detected near the telephone terminal 300 in an emergency, an evacuation guidance message 261c for the guest is sent to the telephone terminal 300. Also, when a wireless IP terminal 400 carried by an employee is detected near the telephone terminal 300, an evacuation guidance message 261d for the employee is sent to the wireless IP terminal 400.

That is, the message sending unit 230 identifies the nearest telephone terminal 300 and the user category based on the position of each wireless IP terminal 400 acquired by the position acquisition unit 220. If the user is a guest, an evacuation guidance message 261c for the guest is sent. On the other hand, if the user is an employee, an evacuation guidance message 261d for the employee is sent to the wireless IP terminal 400 carried by the employee. Details will be described later.

The flow of each process is explained below.

[Presettings]
First, the pre-setting process will be described. Fig. 5 is a diagram for explaining the flow of the pre-setting process. The pre-setting process is a process performed when the access point 500 is installed, and is a process for generating and updating the message table 261. The pre-setting process is performed when the access point 500 is newly installed or when the installation location is changed. In this embodiment, the front terminal 320 is used as an input/output terminal of the key telephone device 200 as an example.

The front desk clerk inputs the necessary information, such as the IP address of the access point (AP) 500 and its installation location, into the message table 261 via the front desk terminal 320 (step S1101).

When the information management unit 210 receives input from the front clerk via the front terminal 320, it instructs the memory unit 260 to register the received information in the message table 261 (step S1102). The memory unit 260 updates the message table 261 by registering the information in the message table 261 in accordance with the instruction (step S1103). For example, if a new access point 500 is added, a new record is added, and if information about an existing access point 500 is changed, the relevant information in the relevant record is changed. Finally, the update result is stored in the message table 261.

[Check-in process]
Next, the process at the time of check-in (check-in process) will be described. Fig. 6 is a diagram for explaining the check-in process. The check-in process is a process for registering a smartphone carried by a guest in the wireless IP terminal table 262 as the wireless IP terminal 400 of the key telephone system 100 of this embodiment. Note that the same process is performed for an employee when the wireless IP terminal 400 is handed over to the employee.

As mentioned above, it is assumed here that a dedicated application is pre-installed on the guest's smartphone. The dedicated application is assumed to have an ID (identification information) registered that uniquely identifies each smartphone. Note that the smartphone's phone number, etc. may be used instead of the ID.

When checking in, the front desk clerk issues an instruction to start the check-in process via the front desk terminal 320. The front desk terminal 320 sends the received instruction to start the process to the information management unit 210 (step S1201).

For example, an instruction to start check-in is preregistered in a specific button on the front desk terminal 320. In other words, when the front desk terminal 320 receives a press of the button, it determines that it has received an instruction to start check-in, and transmits a start instruction to the key telephone device 200. The same applies to other processes below.

The guest uses a dedicated application to connect his/her smartphone to the access point 500 in the hotel (step S1202) and notifies the key telephone device 200 of his/her ID.

The access point 500 transmits the notified ID to the information management unit 210 (step S1203).

The information management unit 210 obtains the wireless IP extension number to be assigned to the guest's smartphone from the storage unit 260 (step S1204). For example, the storage unit 260 refers to the wireless IP terminal table 262 and provides an unused wireless IP extension number to the information management unit 210.

The information management unit 210 assigns the acquired wireless IP extension number to the guest's smartphone via the access point 500, making it the wireless IP terminal 400 (steps S1205 and S1206). It also notifies the front desk terminal of the acquired wireless IP extension number (step S1207).

The front desk terminal 320 that has received the notification accepts input of the guest name and category from the front desk clerk and transmits it to the information management unit 210 (step S1208). The information management unit 210 then instructs the memory unit 260 to register the received guest name and category in the wireless IP terminal table 262 in association with the notified wireless IP extension number (step S1209). The memory unit 260 adds a record to the wireless IP terminal table 262 in accordance with the instruction (step S1210) and ends the process.

[Checkout process]
Next, the process at the time of check-out (check-out process) will be described. Fig. 7 is a diagram for explaining the check-out process. The check-out process is a process for deleting information related to the wireless IP terminal 400 used by the guest from the wireless IP terminal table 262. The same process is also performed when an employee gives up the wireless IP terminal 400.

The front desk clerk issues an instruction to start check-out via the front desk terminal 320. The front desk terminal 320 sends the received instruction to the information management unit 210 (step S1301).

The information management unit 210 requests and obtains a list of the wireless IP terminal table 262 from the storage unit 260 (step S1302). It then sends this to the front terminal 320 (step S1303).

The front desk terminal 320 presents the received list to the front desk clerk and accepts the designation of the guest who is checking out, i.e., the designation of the person to be deleted. The front desk terminal 320 then transmits the accepted deletion designation to the information management unit 210 (step S1304).

The information management unit 210 issues a deletion instruction to the memory unit 260 in accordance with the received deletion instruction, and the memory unit 260 deletes the specified record from the wireless IP terminal table 262 (step S1306) and terminates the process.

After completing the process, the front desk clerk may ask the guest to delete the dedicated application.

In addition, in the above process, the front desk terminal 320 may accept the name of the guest checking out and transmit it to the information management unit 210 without performing steps S1301 to S1303. In this case, the information management unit 210 instructs the memory unit 260 to delete the record containing the accepted guest name.

[Emergency procedures for guests]
Next, the process in the event of an emergency will be described. First, the process for guests will be described. Fig. 8 is a diagram for explaining the process in the event of an emergency for guests. In the event of an emergency, the key telephone system 100 of this embodiment outputs a message from the telephone terminal 300 located in the vicinity of each guest, encouraging each guest to take the best possible evacuation route.

When an emergency occurs, the front desk clerk issues an instruction to start evacuation guidance via the front desk terminal 320. In response, the front desk terminal 320 sends an instruction to start evacuation guidance to the key telephone device 200 (step S1401).

When the key telephone device 200 receives an instruction to start evacuation guidance, the location acquisition unit 220 first performs location acquisition processing for each wireless IP terminal in the hotel.

Here, the location acquisition unit 220 transmits a wireless IP terminal search instruction to each access point 500 (step S1402). Each access point 500 that receives the wireless IP terminal search instruction searches for a wireless IP terminal 400 that is connected (belongs) to the own device (step S1403), acquires the wireless IP extension number (step S1404), and returns the wireless IP extension number together with the IP address of the own device (access point 500) to the location acquisition unit 220 (step S1405). This allows the location acquisition unit 220 to know the nearby wireless IP terminals 400 for each access point 500.

The location acquisition unit 220 transmits the wireless IP extension number of the wireless IP terminal 400 belonging to each access point 500 acquired for that access point 500 to the message sending unit 230 as the location information of each wireless IP terminal 400 (step S1406).

The message sending unit 230 first refers to the wireless IP terminal table 262 and identifies the user name 262b and user category 262c of each wireless IP terminal 400 having the acquired wireless IP extension number (steps S1407 and S1408).

Then, the message sending unit 230 performs the following processing for the wireless IP terminal 400 whose user category 262c is a guest.

First, the message sending unit 230 refers to the message table 261 and obtains the telephone terminal extension number 261b of the nearest guest room terminal 310 and an evacuation guidance message 261c for guests from the IP address 261a of the access point to which the wireless IP terminal 400 currently belongs (step S1411).

Then, the message sending unit 230 creates a voice message to be output using the user name 262b identified in step S1407 and the evacuation guidance message 261c for the guest obtained in step S1411 (step S1412).

The message sending unit 230 calls the extension number of the guest room terminal 310 obtained in step S1411 and sends the created voice message (step S1413). It also registers the fact that the guest room terminal 310 is being called in the called guest name 261f in the message table 261 (step S1414). At this time, the user name 262b identified in step S1407 is registered.

By the above process, in the event of an emergency, an evacuation guidance message, for example, by voice, is output from the telephone terminal 300 located near the guest's wireless IP terminal 400.

[Emergency procedures for employees]
Next, the process for employees in the event of an emergency will be described. Fig. 9 is a diagram for explaining the process for employees in the event of an emergency. The process for employees in the event of an emergency is a process for notifying employees that there is a guest nearby. Note that up to step S1408, the process for employees in the event of an emergency is the same as the process for guests in the event of an emergency described above, and therefore the description will be omitted.

For the wireless IP terminal 400 whose user category 262c identified in step S1408 is an employee, the message sending unit 230 performs the following process.

First, the message sending unit 230 refers to the message table 261 and determines whether the called guest name 261f is registered in the IP address 261a of the access point to which the wireless IP terminal 400 currently belongs.

If registered, the registered user name 262b and the registered message from the evacuation guidance message for employees 261d are obtained (step S1421). If the called guest name 261f is not registered, the message from the evacuation guidance message for employees 261d when the guest is not present is obtained.

If the called guest name 261f is registered, the message sending unit 230 creates a message using the registered user name 262b and the registered message (step S1422).

Then, the message sending unit 230 sends the generated message (or the absence message) to the wireless IP extension number of the wireless IP terminal 400 via the access point 500 (steps S1423, S1424).

It is expected that both guests and employees will move in the event of an emergency. Therefore, the above-mentioned emergency processing from step S1402 onwards is executed repeatedly at a predetermined time interval.

[Concrete example]
Here, a specific example of emergency processing for guests will be described. Here, consider the case where AA Yama (guest) is staying in room 3301. AA Yama has a wireless IP terminal 400 with a wireless IP extension number of "4410." This wireless IP terminal 400 uses an access point 500 (IP address: 172.16.0.201) installed in room 3301.

When an emergency occurs, the location acquisition unit 220 searches for the wireless IP terminal 400 via the access point 500. For example, it sends a search message. The access point 500 receives the wireless IP extension number (here, "4410") from the wireless IP terminal 400, and replies to the location acquisition unit 220 with the wireless IP extension number "4410" along with its own device's IP address (here, "172.16.0.201").

The location acquisition unit 220 notifies the message sending unit 230 of the acquired IP address "172.16.0.201" and wireless IP extension number "4410".

The message sending unit 230 refers to the wireless IP terminal table 262 and obtains that the user name 262b of the wireless IP extension number 262a "4410" is "AA Yama" and the user category 262c is "guest."

The message sending unit 230 also references the message table 261 and obtains the telephone terminal extension number 261b "3301" and the evacuation guidance message 261c for guests "Mr. ***, go out into the hallway and turn left" from the record with the IP address 261a "172.16.0.201."

The message sending unit 230 combines the acquired user name 262b with the evacuation guidance message 261c for guests to generate an evacuation guidance message such as "AA Yama-san, go out into the hallway and turn left." Then, it makes a voice call to the guest room terminal 310 with the extension number "3301" and plays the evacuation guidance message such as "AA Yama-san, go out into the hallway and turn left."

As described above, if the wireless IP terminal 400 with the wireless IP number "4410" moves and starts using, for example, an access point (IP address: 172.16.1.202), an evacuation guidance message saying "AA Yama, please head to the stairwell" is sent to the guest room terminal 310 with the extension number "3302" and played.

Mr. AA Yama, a guest staying in room 3302, follows the evacuation guidance message and evacuates.

Next, we will explain the process for employees in the event of an emergency with a specific example. While calling a guest "Mr. AA Yama", employee "CC Oka" is near room 3301. The wireless IP terminal 400 carried by employee "CC Oka" has a wireless IP extension number of "4412" and is using an access point with an IP address of "172.16.0.201".

When an emergency occurs, the location acquisition unit 220 searches for the wireless IP terminal 400 via the access point 500. The access point 500 receives the wireless IP extension number (here, "4412") from the wireless IP terminal 400 and replies to the location acquisition unit 220 together with its own device's IP address (here, "172.16.0.201").

The location acquisition unit 220 notifies the message sending unit 230 of the acquired IP address "172.16.0.201" and wireless IP extension number "4412".

The message sending unit 230 refers to the wireless IP terminal table 262 and obtains that the user name 262b of the wireless IP extension number 262a "4412" is "CC Oka" and the user category 262c is "Employee."

Next, the message sending unit 230 refers to the message table 261 and determines whether the called guest name 261f is registered in the record with the IP address 261a of "17216.0.201".

For example, assume that "AA Yama" is registered in the called guest name 261f. The message sending unit 230 obtains from the record the registered message "*** is staying in room 3301" in the employee evacuation guidance message 261d. Then, combining this with "AA Yama" registered in the called guest name 261f, a message "AA Yama is staying in room 3301" is generated and sent to the wireless IP terminal 400 whose wireless IP extension number 262a is "4412" to notify it.

Employee "CC Oka" sees this and learns that guest "AA Yama" is staying in room 3301, the closest room to his current location, and is able to guide guest "AA Yama" to safety.

On the other hand, if no one is registered in the called guest name 261f, the message sending unit 230 retrieves the absence message "There are no guests in this area" from the record in the evacuation guidance message 261d for employees. Then, the message is sent to the wireless IP terminal 400 with the wireless IP extension number 262a of "4412" to notify it.

When employee CC Oka sees this, he realizes that there are no guests in Room 3301, the closest room to his current location, and is able to carry out the evacuation guidance actions he had planned in advance.

[Hardware configuration of key telephone device]
Here, the hardware configuration of the key telephone device 200 of this embodiment will be described. Fig. 2(b) is a hardware configuration diagram of the key telephone device 200 of this embodiment. As shown in this figure, the key telephone device 200 of this embodiment includes, for example, a controller 291, a communication I/F 292, a telephone network control device 293, and an IP network control device 294.

The controller 291 includes a CPU (Central Processing Unit) and a storage device (memory), and controls each part of the key telephone device 200.

The CPU, for example, loads and executes a program stored in the storage device. Note that one or more processors, such as an MPU (Micro Processing Unit), may be used instead of the CPU. The storage device stores the programs executed by the key telephone device 200, and is also used as a work area when the CPU processes these.

The communication I/F 292 transmits and receives signals and data via wired or wireless connections. For example, it includes an external line I/F for connecting to an external telephone network, an internal line I/F for connecting to an internal telephone, and a network I/F for connecting to a network such as a LAN (IP network 900). The network I/F communicates with wireless terminals such as smartphones and other communication devices including a push notification server via the IP network 900.

The telephone network control device 293 performs call control processing in cooperation with the internal telephones (telephone terminals 300) and the external telephone network according to a predetermined call control procedure. This establishes and releases communication paths between internal telephones, or between internal telephones and telephones on the external telephone network side. The established communication paths are then used to relay calls between internal telephones, or between internal telephones and telephones on the external telephone network side.

The IP network control device 294 performs the necessary processing as a main device that provides internal telephone services to wireless telephone terminals (wireless IP terminals 400). Specifically, it establishes communication paths between wireless telephone terminals and releases established communication paths by sending and receiving call control messages to and from wireless telephone terminals according to a specified call control protocol such as SIP (Session Initiation Protocol). It also relays voice or video voice calls between wireless telephone terminals via communication paths according to a specified transmission protocol such as RTP (Realtime Transport Protocol).

Each of the above-mentioned functions of the key telephone device 200 of this embodiment is realized by the CPU loading and executing a program stored in the storage device. In addition, the message table 261, the wireless IP terminal table 262, etc. may be constructed in the storage device. In addition, data generated during processing is stored in the storage device.

Note that the hardware configuration of the key telephone device 200 is not limited to this. It may also include hardware not shown.

[Hardware configuration of telephone terminal]
The telephone terminal 300 may be a key telephone housed in the key telephone device 200, or may be an IP telephone (or a smartphone) for making voice calls over an IP network in accordance with VoIP (Voice over Internet Protocol).

[Hardware configuration of wireless IP terminal]
The wireless IP terminal 400 of the present embodiment is realized, for example, by a general smartphone or the like that includes a CPU, a memory, a communication interface (I/F), a display, etc. Each of the above functions is realized by downloading and installing a dedicated application prepared in advance from a server on a network.

As described above, a dedicated wireless IP terminal equipped with the above functions and capable of IP communication may be used. A wireless IP extension number may be assigned to the dedicated wireless IP terminal in advance. For example, the wireless IP terminal used by employees may be realized as a dedicated device, and for guests, it may be realized as a dedicated application. Of course, a dedicated wireless IP terminal may be provided for guests who do not have a smartphone.

As described above, according to this embodiment, the presence or absence of a guest in the vicinity of the telephone terminal 300 is determined based on the wireless IP extension number assigned to the guest's smartphone (wireless IP terminal 400) at check-in and the location of the access point 500 used by the smartphone (wireless IP terminal 400), and if it is determined that a guest is present, an evacuation guidance message optimal for that area is sent and output to the telephone terminal 300. Therefore, it is possible to provide the guest with the necessary and sufficient evacuation guidance message efficiently and without waste.

In addition, in the event of an emergency, appropriate messages can be sent to employees depending on whether there are any guests near their current location. This means that employees do not need to go round each guest room unnecessarily to check whether guests are present. This allows for efficient evacuation guidance.

Furthermore, according to this embodiment, the names of guests who are staying temporarily are registered in association with the wireless IP terminal 400. Therefore, messages with names can be sent. In the event of an emergency, guests can distinguish their own evacuation guidance message from the large number of evacuation guidance messages being output.

As described above, this embodiment enables efficient evacuation guidance in facilities with many temporary residents, improving safety.

<<Second embodiment>>
Next, a second embodiment to which the present invention is applied will be described. In this embodiment, the location of the wireless IP terminal 400 is acquired by a beacon. The following description of this embodiment will focus on the configuration that differs from the first embodiment.

Figure 10 is an overall configuration diagram of the key telephone system 100a of this embodiment. In addition to the configuration of the first embodiment, the key telephone system 100a of this embodiment further comprises multiple beacon transmitters 600 and a location management server 700.

The beacon transmitter 600 outputs a beacon including a beacon ID at a predetermined time interval. The beacon transmitter 600 is installed near the telephone terminal 300, for example, near the entrance of the guest room, near the elevator entrance, near the stairs, in the hallway, etc.

The location management server 700 is connected to the key telephone device 200 via the IP network 900, and manages the locations of the wireless IP terminals 400. In this embodiment, each beacon is associated with a telephone terminal 300 and managed as a beacon table 710.

An example of the beacon table 710 is shown in FIG. 11(a). As shown in this figure, in the beacon table 710, the extension number 710b of the telephone terminal 300 nearest to each beacon transmitter 600 is registered in the beacon ID 710a included in the beacon output by the beacon transmitter 600.

When the wireless IP terminal 400 of this embodiment receives a beacon, it transmits the beacon ID contained in the beacon and the assigned wireless IP extension number as identification information for the own device (wireless IP terminal 400) to the location management server 700. In addition, the process of transmitting the beacon ID and wireless IP extension number is realized by a dedicated application installed in the wireless IP terminal 400. Note that instead of the wireless IP extension number, an ID registered by the dedicated application may be transmitted.

Each time the location management server 700 receives a wireless IP extension number and a beacon ID as location information from a wireless IP terminal 400, it associates them with the reception date and time and stores them in the wireless IP location table 720. An example of the wireless IP location table 720 is shown in FIG. 11(b).

The wireless IP location table 720 stores the wireless IP extension number 720b and beacon ID 720c acquired at the date and time 720a in association with that date and time. When information of the same wireless IP extension number 720b is received, the record with the oldest reception date and time may be deleted. Also, the wireless IP location table 720 may be provided for each wireless IP extension number, and may be configured to register the date and time and the beacon ID.

In this embodiment, when a guest checks out, the information management unit 210 instructs the location management server 700 to delete from the wireless IP location table 720 all records related to the wireless IP extension number of the wireless IP terminal 400 used by the guest who has checked out. The same is true when an employee leaves the hotel. As a result, only the data of guests and employees currently staying at the hotel is retained.

In this embodiment, in the event of an emergency, the location acquisition unit 220 accesses the location management server 700 and acquires the latest location information for each wireless IP terminal 400. In this embodiment, for each wireless IP extension number 720b registered in the wireless IP location table 720, the beacon ID 720c associated with the latest wireless IP extension number 720b is acquired. The location acquisition unit 220 then refers to the beacon table 710 and acquires the extension number of the nearest telephone terminal 300.

As in the first embodiment, the message sending unit 230 refers to the wireless IP terminal table 262 and identifies the category of the user of the wireless IP terminal 400 that has each wireless IP extension number 720b registered in the wireless IP location table 720 as the wireless IP extension number 262a. If the category is a guest, an evacuation guidance message is sent to the nearest telephone terminal 300 that has been obtained.

Other functions and processing are the same as in the first embodiment.

In this embodiment, the access point 500 does not have to be provided. In this case, no pre-setting is required. Also, no processing related to the access point 500 at check-in, etc. is required.

According to this embodiment, the current location can be identified with high accuracy even if, for example, there are fewer access points 500 installed than there are guest rooms. Therefore, in addition to the effect obtained in the first embodiment, evacuation guidance messages can be provided to guests with even higher accuracy.

Of course, the method of the first embodiment using the access point 500 and the method of the second embodiment using the beacon transmitter 600 can be used together to obtain the location of a wireless IP terminal.

<Modification 1>
In the above-described embodiments, when an emergency occurs, the evacuation guidance message 261c for the guest is output to the telephone terminal 300 closest to the guest. However, the present invention is not limited to this. For example, the evacuation guidance message 261c for the guest may be transmitted to the wireless IP terminal 400 of the guest and output.

In this case, in addition to an audio message, for example, screen data (or video data) displaying an evacuation route may also be registered as the evacuation guidance message 261c.

By configuring it in this way, it is possible to reliably inform each guest of the best evacuation route, even if the guest is in a large guest room or a banquet hall, for example.

<Modification 2>
In the above embodiment, the front desk clerk inputs all information stored in the message table 261 each time an access point 500 is added or changed, but this is not limited to the above. For example, the location of each guest room terminal 310, and the evacuation guidance message for guests and the evacuation guidance message for employees corresponding to the location may be stored in advance as a guest room terminal table in association with the extension number of the guest room terminal 310. In this case, the front desk clerk inputs the extension number of the nearest guest room terminal 310, and the information management unit 210 obtains the corresponding evacuation guidance message for guests, evacuation guidance message for employees, and the installation location of the access point from the guest room terminal table and registers them in the message table 261.

<Modification 3>
In the above embodiment, at the time of check-in, information for identifying the guest's smartphone is transmitted to the key telephone system 100 by a dedicated application, but the present invention is not limited to this.

For example, the above steps S1202 and S1203 may not be performed, and the wireless IP extension number acquired by the information management unit 210 may be sent to the front terminal 320. The front desk clerk may then show the wireless IP extension number received by the front terminal 320 to the guest, who may then enter it into his or her smartphone via a specific screen of a dedicated application.

<Modification 4>
The telephone terminal 300 functioning as an input/output terminal of the key telephone device 200 may be provided not only at the front desk but also in an office or the like, and the classification may be automatically input. For example, when a user name is input from the telephone terminal 300 located at the front desk, the classification is determined as a guest, and when a user name is input from the telephone terminal 300 located in an office, the classification is determined as an employee, and so on.

<Modification 5>
For example, the guidance route may be different in the case of a fire and in the case of an earthquake. Therefore, for example, a plurality of evacuation guidance messages 261c for guests may be prepared according to the type of emergency. In this case, for example, during the evacuation guidance operation in step S1401, the type of emergency is identified and instructions are given.

<Modification 6>
The wireless IP terminal table 262 may be configured to register the characteristics of the guest in response to the request from the guest. In this case, the evacuation guidance message 261c for guests is prepared for each of the guest's characteristics. For example, for people who have difficulty walking, such as people with disabilities or the elderly, the evacuation message 261c may be specially urged to use the elevator, or directed to a specific staircase and made to wait until help arrives. Furthermore, for people who are hearing impaired, the process of flashing the lamp of the telephone terminal 300 instead of outputting a voice message may be registered.

<Modification 7>
As described above, the wireless IP terminal 400 is not limited to a smartphone. For example, as long as it has the above-mentioned information processing function, communication function, etc., the wireless IP terminal 400 may be a portable information processing terminal such as a tablet, a notebook PC (Personal Computer), etc.

The key telephone device 200 is not limited to a key telephone main device. It is sufficient if it is capable of various control processes and communication control of multiple telephones, including IP telephones, and may be, for example, a PBX (Private Branch Exchange).

<Modification 8>
In the above embodiments and modifications, the key telephone system 100 (100a) of the present embodiment is described as being used in a hotel, but the usage environment is not limited to a hotel. The system can be used in any facility where people who need evacuation guidance are present and are staying temporarily.

In the flowchart used in the above explanation, multiple steps (processes) are described in order, but the order in which each step is performed is not limited to the order described. For example, the order of the steps shown in the figure can be changed to the extent that does not interfere with the content, such as performing each process in parallel.

The programs stored in the storage device of the key telephone device 200 can be provided as program products recorded on a non-transitory computer-readable storage medium. These can be used to store various programs recorded on non-transitory computer-readable storage media for the medium to long term.

Although each embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiments, and further modifications, substitutions, and adjustments can be made without departing from the basic technical concept of the present invention. For example, the network configurations and configurations of each element shown in each drawing are examples to aid in understanding the present invention, and are not limited to the configurations shown in these drawings.
