Description

The present invention relates to a telephone system configured by using a so-called power supply hub device, a power supply hub device used in the telephone system, a main device, and a cordless telephone device.

Conventionally, for the purpose of suppressing power consumption, some telephones have used a method in which a power saving state is set when the telephone is in a standby state and an intermittent operation is performed in which the telephone is started at regular intervals. Further, in Patent Document 1 described later, labor saving is performed by using a second power source different from that at the time of use so as to detect off-hook with a small current when the power is saved in the standby state. Inventions relating to communication devices and the like are disclosed.

When these technologies are used, the power consumption during standby can be reduced to some extent. However, even if an intermittent operation is performed or the invention described in Patent Document 1 is in a power saving state, the user can use the telephone immediately when he / she wants to use the telephone. The minimum power is supplied to the phone to properly detect the off-hook operated by. Therefore, it was not possible to completely stop the power supply to the telephone, and there was a limit to power saving.

In companies and the like, a business phone system (button telephone system) is constructed and used by connecting a plurality of telephones to a so-called main device. In the case of a business phone system, the number of telephones connected to the main device is large, so power saving of telephones is an important issue. In recent years, a business phone system has also been constructed by connecting a cordless telephone device to a main device via a power supply hub device. In a cordless telephone, for example, a master unit that constitutes a main unit equipped with operation keys such as a numeric keypad and a slave unit that constitutes a handset part (handset) are connected by short-range wireless communication, and a cord connecting the master unit and the slave unit is connected. There is no such thing.

The PoE function is a technology for supplying electric power to connected devices through a LAN cable (twisted pair cable) used when constructing a LAN (Local Area Network). Therefore, the master unit of the cordless telephone device connected to the power supply hub device can receive power from the power supply hub device, and does not need to be individually connected to the commercial power supply via the AC adapter. A cordless telephone device, etc. can be installed in places where the power cannot be secured. On the other hand, the slave unit is equipped with a battery, and when it is mounted on the master unit, the battery can be charged, and when it is away from the master unit, the power is supplied from the built-in battery to the master unit. Wireless communication is possible with and, and it functions as a telephone.

Then, in the power supply hub device, power supply can be stopped at each connection port to which the master unit of each cordless telephone device is connected. Therefore, if the power supply from the power supply hub device is stopped, the power supply to the master unit of the cordless telephone device can be completely stopped, so that further labor saving can be achieved. However, if the power supply to the master unit is stopped, wireless communication between the master unit and the slave unit becomes impossible, so that the cordless telephone device does not function as a telephone. Therefore, the reality is that the power supply through the connection port to which the cordless telephone device is connected cannot be stopped.

[Telephone system configuration example]
FIG. 1 is a block diagram showing an overall configuration example of the telephone system of this embodiment. In the telephone system of this example, a plurality of cordless telephone devices 31, 32, ..., 3n are connected to the main device 1 via the power supply hub device 2 as an extension telephone. Note that the character n used as a subscript, such as the cordless telephone device 3n, means an integer of 1 or more. For example, in FIG. 1, since the cordless telephone devices 31 and 32 exist, FIG. The subscript n in is an integer of 3 or more. The subscript n is used in the same manner below.

Each of the cordless telephone devices 31 to 3n has a base set (main body) BS1, BS2, ..., BSn as a master unit, and a handset HS1, HS2, ..., HSn as a slave unit, respectively. Consists of. Each of the master units BS1 to BSn and each of the slave units HS1 to HSn are wirelessly connected. That is, each of the cordless telephone devices 31 to 3n is a business phone (button telephone) called a so-called curl cordless telephone device, which does not have a cord for connecting the master unit and the slave unit.

A Bluetooth (registered trademark) method or a DECT (registered trademark) method is used for wireless connection between each of the master units BS1 to BSn of the cordless telephone devices 31 to 3n and each of the slave units HS1 to HSn. The Bluetooth (registered trademark) method communicates between a master unit and a slave unit using a signal in the 2.4 GHz band, and in many cases, wireless communication is possible within a distance of about 10 m. The DECT (registered trademark) method uses a 1.9 GHz band signal to communicate between the master unit and the slave unit, is less affected by interference, and is often within a distance of several tens of meters. Wireless communication is possible.

It is possible to wirelessly connect a plurality of slave units to each of the master units BS1 to BSn, but in this example, one slave unit is connected to one master unit. It is said that it is configured. Although not shown, the extension telephone device connected to the main unit 1 is not only a cordless telephone device 31, 32, ..., 3n, but also a digital button telephone terminal, like a normal business phone. It is also possible to do.

As will be described later, the main device 1 has a SIP (Session Initiation Protocol) server function, and is described as a telephone line connected to an IP (Internet Protocol) network and a conventional public switched telephone network (hereinafter, simply referred to as a telephone network). It can accommodate a telephone line connected to.). Then, the master units BS1 to BSn of the cordless telephone devices 31 to 3n are connected to the main device 1 via the power supply hub device 2. The main device 1 performs call control, circuit switching control, and other control as a business phone for a plurality of cordless telephone devices 31 to 3n.

The power supply hub device 2 is one of the relay devices of the communication network, has a plurality of connection ports for LAN connection, and does not transmit the received data to all the devices connected to each connection port, but sends the destination. It has a function to confirm and send only to related devices. Further, the power supply hub device 2 has a function of generating a reference synchronization signal SYNC (first synchronization signal) and supplying it to each of lower-level devices such as a plurality of cordless telephone devices 31 to 3n connected to the connection port of the own device. It has.

Further, the power supply hub device 2 has the above-mentioned PoE function, and is connected to, for example, a commercial power source to receive power, and is connected to the connection port of the own device via LAN. Drive power is supplied to each of the BSn. As described above, the power supply hub device 2 is a power supply device (PSE (Power Sourcing Equipment)), and the master units BS1 to BSn of the cordless telephone devices 31 to 3n are power receiving devices (PD (Powered Device)). As a result, each of the master units BS1 to BSn of the cordless telephone devices 31 to 3n connected to the power supply hub device 2 via LAN does not need to secure their own power supply, so that they are arranged in a place where there is no outlet for commercial power supply. Is also possible.

As will be described later, the power supply hub device 2 is provided with a switching unit for switching drive power supply / stop to the master units BS1 to BSn, which are power receiving devices, for each of the plurality of connection ports. Further, the power feeding hub device 2 includes a switching control unit that controls switching of the switching unit according to a control signal supplied from the main device 1. Then, in addition to call control and circuit switching control for the cordless telephone devices 31 to 3n, the main device 1 of this embodiment also controls the supply of drive power to the master units BS1 to BSn through the power supply hub device 2. .. Therefore, although the details will be described later, the main device 1 manages which cordless telephone device is connected to each of the plurality of connection ports of the power supply hub device 2.

The supply control of the drive power to the master units BS1 to BSn performed by the main unit 1 can be performed according to the settings through the system mode setting, the Web setting, the menu of the cordless telephone device, and the like. The system mode setting is for setting the entire system directly to the main device 1 through, for example, an operation unit connected to the main device 1. Further, the Web setting is performed for the main device 1 by accessing the main device 1 through the Internet using, for example, a personal computer. The setting through the menu or the like of the cordless telephone device is performed for the main device 1 through the cordless telephone device connected to the power supply hub device 2.

In this way, setting information for controlling the power supply / stop of the drive power is set for each connection port of the power supply hub device 2 through some paths for the main device 1, and the main device 1 is set accordingly. However, the supply / stop of the drive power can be controlled for each connection port of the power supply hub device 2. If the supply of the drive power to the master units BS1 to BSn can be completely stopped, the power consumption of the cordless telephone device can be reduced as compared with the case of intermittent operation as in the conventional case.

However, when the supply of drive power to all the master units BS1 to BSn of the cordless telephone devices 31 to 3n connected to the power supply hub device 2 is stopped, the functions of the master units BS1 to BSn are completely stopped and cordless. The telephone devices 31 to 3n cannot be used. In this way, when the supply of drive power to the master units BS1 to BSn is stopped, the cordless telephone device 31 to 3n cannot be used in an emergency, and the telephone system plays a role. I can't do enough.

Here, we focus on the respective configurations of the master unit and the slave unit that make up the cordless telephone device. The master units BS1 to BSn cannot operate unless the drive power is supplied from the power supply hub device 2. However, since the slave units HS1 to HSn can receive the drive power from the built-in battery, they can operate even when the drive power is not supplied to the master units BS1 to BSn. In the telephone system of this embodiment, even if the driving power is not supplied to the master units BS1 to BSn and all the functions are stopped, the corresponding slave units HS1 to HSn can operate because they are battery-powered. Is used to control the supply of drive power.

Specifically, in the telephone system of this embodiment, for example, from 8:00 pm to 8:00 am, the supply of drive power to the master unit of the cordless telephone devices 31 to 3n connected to the power supply hub device 2 is stopped. Suppose that it is controlled as follows. In this case, at least one master unit among the master units BS1 to BSn connected to the power supply hub device 2, for example, the master unit BS1 is supplied with drive power through the power supply hub device 2, for example, intermittent reception is performed. Maintain a working state. Then, it is assumed that the slave unit HS3 corresponding to the master unit BS3, for example, from which the supply of the drive power is stopped is set to off-hook. In this case, the slave unit HS3 notifies the main unit 1 of the power supply restart request including the identification information of the cordless telephone device 33 through the master unit BS1 in which the supply of the driving power is maintained.

As a result, the main device 1 supplies drive power to the master unit BS3 through the connection port to which the master unit BS3 of the cordless telephone device 33 is connected, based on the identification information of the cordless telephone device 33 included in the power supply restart request. The power feeding hub device 2 is controlled so as to restart. As a result, the supply of drive power to the master unit BS3 corresponding to the slave unit HS3 operated off-hook is restarted, and the cordless telephone device 33 including the master unit BS3 and the slave unit HS3 becomes available.

As described above, in the telephone system of this embodiment, the cordless telephone devices 31 to 3n connected to each connection port of the power supply hub device 2 are driven to the master units BS1 to BSn under the control of the main device 1. Power supply / stop can be controlled. Then, drive power is supplied to one of the master units BS1 to the master unit BSn to operate the master unit. After that, when the slave unit corresponding to the master unit whose drive power supply is stopped is off-hooked, the supply restart request from the off-hooked slave unit is sent to the main unit 1 through the master unit to which the drive power is supplied. Send to. As a result, the main device 1 can control the power supply hub device 2 to restart the supply of the drive power to the master unit corresponding to the off-hook slave unit.

Hereinafter, a configuration example of the main device 1 constituting the telephone system of this embodiment, the power supply hub device 2, the master units BS1 to BSn and the slave units HS1 to HSn constituting the cordless telephone devices 31 to 3n will be described. ..

Then, the example of the power supply restart request shown in FIG. 9F requests the restart of the supply of the drive power to the master unit BS2 of the cordless telephone device 32 whose reference number is specified as "002".

Therefore, the power supply off master unit notification in FIG. 9B can instruct the power supply continuation master unit to process the power supply restart request from the cordless telephone device slave unit. Then, by the power supply off instruction of FIG. 9C, the main device 1 can instruct the power supply hub device 2 to stop the supply of the drive power to the master unit of the target cordless telephone device. On the contrary, the main device 1 supplies the drive power to the power supply hub device 2 according to the power supply on instruction in FIG. 9D, and the drive power is supplied to the master unit of the cordless telephone device, which is the target.

It is assumed that the master units BS2 to BS7 of 32 to 37 are notified to be power-off master units.

<Processing of main device 1>
FIG. 10 is a flowchart for explaining a process related to drive power supply control performed by the main device 1. The process shown in FIG. 10 is a process that is always executed mainly by the power supply management unit 106 under the control of the control unit 120 of the main device 1 to which the power is turned on. The power supply management unit 106 turns off the power supply of the drive power to the subordinate cordless telephone device based on the stored data of the drive power on / off table 108 (FIG. 4) and the current time provided by the clock circuit (not shown). Is determined (step S101).

In the determination process of step S101, it is determined that the timing for turning off the power supply of the drive power has arrived. In this case, the power supply management unit 106 forms the power supply off instruction described with reference to FIG. 9C and transmits it to the power supply hub device 2 (step S102). The power supply off instruction described with reference to FIG. 9C is to the master units BS2 to BS7 of the cordless telephone devices 32 to 37 connected to the connection ports 2P (2) to 2P (7) of the power supply hub device 2. It is intended to stop the supply of drive power. This power supply off instruction can be formed based on the stored data of the drive power on / off table 108 described with reference to FIG. 4 and the stored data of the connected device management table 107 described with reference to FIG.

Further, in step S102, the power status of the status management table 109 is also updated so that the cordless telephone device whose drive power supply has been stopped can be identified. Then, in the determination process of step S101, when it is determined that the timing for turning off the power supply of the drive power has not arrived, and after the process of step S102, the determination process of step S103 is executed.

That is, the power supply management unit 106 refers to the stored data in the status management table 109 (FIG. 5) and determines whether or not there is a master unit of the cordless telephone device in which the supply of drive power is turned off (step S103). .. In the determination process of step S103, when it is determined that the master unit of the cordless telephone device for which the supply of drive power is turned off does not exist, the process from step S101 is repeated.

Further, it is assumed that in the determination process of step S103, it is determined that there is a master unit of the cordless telephone device in which the supply of drive power is turned off. In this case, the power supply management unit 106 turns on the supply of the drive power to the subordinate cordless telephone device based on the stored data of the drive power on / off table 108 (FIG. 4) and the current time provided by the clock circuit (not shown). It is determined whether or not the timing to be set has arrived (step S104).

When it is determined in the determination process of step S104 that the timing for turning on the supply of the drive power to the subordinate cordless telephone device has arrived, in this case, the power supply management unit 106 has described with reference to FIG. 9D. A power supply on instruction is formed and transmitted to the power supply hub device 2 (step S105). The power supply on instruction described with reference to FIG. 9D is to the master units BS2 to BS7 of the cordless telephone devices 32 to 37 connected to the connection ports 2P (2) to 2P (7) of the power supply hub device 2. It is intended to restart the supply of drive power. This power supply on instruction can be formed based on the stored data of the drive power on / off table 108 described with reference to FIG. 4 and the stored data of the connected device management table 107 described with reference to FIG.

Further, in step S105, the power status of the status management table 109 is updated so that the cordless telephone device to which the drive power is supplied can be appropriately identified. Then, after the process of step S105, the control unit 120 repeats the process from step S101.

Further, in the determination process of step S104, it is determined that the timing for turning on the supply of the drive power to the subordinate cordless telephone device has not arrived. In this case, the power supply management unit 106 receives the power supply restart request shown in FIG. 9 (E) from the power supply continuation master unit, in this example, the master unit BS1 of the cordless telephone device 31 through the LANI / F111. (Step S106). Then, it is determined whether or not the power supply restart request from the power supply continuation master unit has been received (step S107).

In the determination process of step S107, when it is determined that the power supply restart request from the power supply continuation master unit has been received, the power supply management unit 106 gives a power supply on instruction to the power supply off master unit for which the power supply restart is requested (FIG. 9 (D). )) Is formed and transmitted to the power feeding hub device 2 (step S108). As a result, the supply of drive power to the master unit of the cordless telephone device for which the power supply restart request has been made is resumed, and the cordless telephone device can function as a cordless telephone device. Step S In the determination process of step S107, when it is determined that the power supply restart request from the power supply continuation master unit has not been received, and after the process of step S108, the control unit 120 repeats the process from step S101. To do so.

In this way, the main device 1 controls the power supply hub device 2 by executing the process of the flowchart shown in FIG. 10, and the cordless telephone devices 32 to 3n connected to the power supply hub device 2 On / off control of the drive power supply can be performed for each. On / off control of the drive power in this case means controlling whether the drive power is supplied or the supply is completely stopped.

Therefore, since the supply of the driving power can be completely stopped, it is possible to maximize the labor saving of the power consumption of the cordless telephone device. However, the supply of drive power is not stopped for the continuous power supply master unit, and the drive power is supplied in response to the request from the battery-powered slave unit of the cordless telephone device that has stopped the supply of drive power. It also has a route that allows it to resume. This also prevents the cordless telephone device, which has stopped supplying the driving power, from becoming completely unusable.

The power supply hub device 2 with the power turned on first starts a process of transmitting the received data received by the own device to an appropriate destination (step S201).

Next, the switching control unit 22 receives the control signal from the main device 1 (step S202), and determines whether or not the control signal from the main device 1 has been received (step S203). When it is determined in the determination process of step S203 that the control signal from the main device 1 has not been received, the switching control unit 22 repeats the process from step S202. When it is determined in the determination process of step S203 that the control signal from the main device 1 has been received, the switching control unit 22 determines whether the control signal is a power supply off instruction of the classification "92" (FIG. 9 (C)). Whether or not it is determined (step S204).

It is assumed that in the determination process of step S204, it is determined that the received control signal from the main device 1 is a power supply off instruction. In this case, the switching control unit 22 controls the switching unit corresponding to the instructed connection port among the switching units 27 (2) to 27 (n), and is the parent of the cordless telephone device through the instructed connection port. The supply of drive power to the machine is stopped (step S205). After that, the switching control unit 22 repeats the process from step S202.

When it is determined in the determination process of step S204 that the received control signal from the main device 1 is not a power supply off instruction, the switching control unit 22 sends a power supply on instruction to the received control signal from the main unit 1 (FIG. 9 (FIG. 9). D)) It is determined whether or not it is (step S206). It is assumed that in the determination process of step S206, it is determined that the received control signal from the main device 1 is a power supply on instruction. In this case, the switching control unit 22 controls the switching unit corresponding to the instructed connection port among the switching units 27 (2) to 27 (n), and is the parent of the cordless telephone device through the instructed connection port. The supply of drive power to the machine is restarted (step S207). After that, the switching control unit 22 repeats the process from step S202.

Further, it is assumed that in the determination process in step S206, it is determined that the received control signal from the main device 1 is not a power supply on instruction. In this case, the switching control unit 22 executes the process according to the received control signal (step S208). For example, in the case of a control signal related to an LED (Light Emitting Diode) to each cordless telephone device 31 to 3n, processing such as providing the control signal to the device to be controlled is performed. After that, the switching control unit 22 repeats the process from step S202.

As described above, the power supply hub device 2 of this embodiment is the master unit BS2 to BSn of the cordless telephone devices 32 to 3n connected to the plurality of connection ports of the own unit based on the control signal from the main device 1. It is possible to control whether or not to supply drive power for each of the above.

<Processing of continuous power supply master unit>
FIG. 12 is a flowchart for explaining the process related to the supply control of the drive power performed by the power supply continuous master unit. The process shown in FIG. 12 is always executed by the control circuit 41 of the power supply continuous master unit (the master unit BS1 of the cordless telephone device 31 in the telephone system of this embodiment) to which the driving power is continuously supplied. This is the process. The control circuit 41 of the master unit BS1 which is the continuous power supply continuous master unit receives a request or the like from a neighboring slave unit through the wireless communication circuit 44 (step S301), and whether or not the request or the like from the slave unit is received. Is determined (step S302).

When it is determined in the determination process of step S302 that the request or the like from the slave unit has not been received, the control circuit 41 repeats the process from step S301. Further, it is assumed that in the determination process of step S302, it is determined that the request or the like from the slave unit has been received. In this case, as described above, a power supply restart request is received from any of the slave units HS2 to HS7 paired for power supply control with respect to the master unit BS1 which is the power supply continuous master unit. It is determined whether or not this has been done (step S303).

It is assumed that in the determination process of step S303, it is determined that the power supply restart request from any of the slave units HS2 to HS7 paired for power supply control has been received. In this case, the control circuit 41 forms a power supply restart request (FIG. 9 (E)), and transmits this to the main device 1 through the line LSI unit 42, the LANI / F47, and the connection port 4P (step S304). As a result, the supply of drive power to the power supply off master unit corresponding to the slave unit that has sent the power supply restart request is restarted, and a call is made using the slave unit that has sent the power supply restart request. Will be able to.

Further, in the determination process of step S303, it is determined that the power supply restart request from any of the slave units HS2 to HS7 paired for power supply control has not been received. In this case, since the received request or the like is a request or the like from the slave unit HS1 corresponding to the power supply continuous master unit, the control circuit 41 executes the process according to the request (step S305). Therefore, in step S305, the call line is connected in response to the incoming call to make a call, or the call line is connected by off-hooking through the slave unit to receive the outgoing information and calling the target party. You will be able to make calls. Then, after the process of step S304 and after the process of step S305, the control circuit 41 repeats the process from step S301.

In this way, the power supply continuation master unit supplies the drive power to the power supply off master unit corresponding to the slave unit in response to the power supply restart request from the slave unit paired for the drive power supply control. You will be able to request a restart.

<Processing of handset>
FIG. 13 is a flowchart for explaining a process related to drive power supply control performed by a slave unit of a cordless telephone device. The process shown in FIG. 13 is a process performed by the control circuit 52 of the slave units HS1 to HSn of all the cordless telephone devices 31 to 3n connected to the power supply hub device 2. Here, for the sake of simplicity, the processing is performed by the slave unit HS2 that constitutes the cordless telephone device 32 together with the master unit BS2 that functions as the power supply off master unit, but the same applies to the slave units of other cordless telephone devices. It is a process performed in.

When the slave unit HS2 of the cordless telephone device 32 is mounted on the BS2 in the master unit, the charging unit 57 charges the battery 58 by receiving power from the master unit BS2. In this case, a signal indicating that power is being supplied from the master unit BS2 is supplied from the charging unit 57 to the control circuit 52. Therefore, when the power supply from the master unit BS2 is cut off due to the slave unit HS2 being picked up by the user from the state of being mounted on the master unit BS2, the control circuit 52 can be determined to be off-hooked. ing.

Further, the operation unit 60 of the slave unit HS2 is provided with an off-hook key. Therefore, even if the slave unit HS2 is not mounted on the master unit BS2, when the off-hook key of the operation unit 60 is operated, a signal indicating this is supplied from the operation unit 60 to the control circuit 52 for control. The circuit 52 can be determined to be off-hook. Therefore, the control circuit 52 of the slave unit HS2 first determines whether or not the own unit is off-hooked (whether or not it is in the off-hook state) (step S401).

When it is determined in the determination process of step S401 that it is not off-hooked, the control circuit 52 repeats the process from step S401 and waits for it to be off-hooked. When it is determined that the device has been off-hook in the determination process of step S401, the control circuit 52 performs out-of-service confirmation by communicating between the own unit and the corresponding master unit BS2 through the wireless communication circuit 51 (step S402). .. That is, the control circuit 52 of the slave unit HS2 that has detected that it has been off-hook sends an off-hook notification to the master unit BS2 corresponding to the own unit, but if the drive power is not supplied to the master unit BS2, the parent unit BS2 No response is returned from the machine BS2. In this case, the slave unit HS2 recognizes that the slave unit is out of the service area where it cannot communicate with the master unit BS2.

Therefore, based on the confirmation process in step S402, the control circuit 52 determines whether or not the own unit is out of the service area where communication with the corresponding master unit HS2 is not possible (step S403). When it is determined in the determination process of step S403 that the own unit is not out of service area, the HS2 is in a state of being able to communicate with the corresponding master unit BS2, so that the normal process after off-hook is executed (step S406). ). As a result, the cordless telephone device 32 including the slave unit HS2 and the master unit BS2 operates as usual, and can make a call and answer an incoming call. After the process of step S406, the control circuit 52 repeats the process from step S401.

On the other hand, when it is determined in the determination process of step S403 that the own unit is out of service area, it is conceivable that the drive power is not supplied to the corresponding master unit HS2 and all the functions thereof are stopped. Therefore, the control circuit 52 forms a power supply restart request (FIG. 9F) and transmits this to the power supply continuation master unit paired for power supply supply control (step S404). In this case, the power supply restart request is the target device with the classification "95", the transmission destination being the reference number "001" corresponding to the master unit BS1, and the transmission source being the reference number "002" corresponding to the slave unit HS2. Is the reference number "002" corresponding to the master unit BS2 corresponding to the slave unit HS2.

In this embodiment, as described above, the power supply continuous master unit is the master unit BS1 of the cordless telephone device 31. Then, the power supply continuation master unit BS1 is paired with the slave units HS2 to HSn for power supply supply control so as to accept the power supply restart request from the slave units HS2 to HSn other than the slave unit HS1 corresponding to the own unit. There is. Then, as described above, the power supply continuation master unit BS1 functions to request the main unit 1 to restart the supply of the drive power to the master unit BS2 corresponding to the slave unit HS2, and the main unit 1 is the power supply hub device. Since 2 is controlled to restart the supply of drive power to the master unit HS2, the slave unit HS2 is in a waiting state until communication with the master unit BS2 corresponding to the own unit becomes possible and is within the range. (Step S405).

In the determination process of step S405, when the control circuit 52 of the HS2 determines that it is within the range of the master unit BS2 corresponding to the own unit, the normal process after the slave unit HS2 is off-hook is performed ( Step S406). As a result, when the slave unit HS2 corresponding to the master unit BS2 whose drive power supply is stopped is off-hooked, the supply of the drive power to the master unit BS2 is restarted to make a call or receive a call. You can answer the phone. As described above, after the process of step S406, the control circuit 52 repeats the process from step S401.

In this way, when the slave unit HS2 of the master unit BS2 whose drive power supply is stopped is used, the main unit 1 is the power supply hub via the master unit BS1 which is the continuous supply master unit. The device 2 can be controlled to restart the supply of drive power to the master unit BS2 and quickly become ready for use. Therefore, even when the drive power is not supplied to the master unit BS2, the supply of the drive power to the master unit HS2 is restarted when the slave unit HS2 corresponding to the master unit BS2 is off-hooked. The cordless telephone device 32 can be appropriately driven and used.

[Stop processing again after restarting the supply of drive power]
For example, during the drive power supply suspension period from 8:00 pm to 8:00 am the next day, the cordless telephone device restarts the supply of drive power to the corresponding master unit BS2 because the slave unit HS2 is off-hooked. It is assumed that 32 is used. After that, for example, when the called call ends and the on-hook state is set, the cordless telephone device 32 has the power status of "1: supplying" and the operation status of "on-hook" according to the stored data of the status management table 109. Become. Further, from the stored data of the drive power on / off table 108, it can be seen that the cordless telephone device 32 has a drive power supply stop period from 8:00 pm to 8:00 am the next day.

In this way, if the drive power is "1: supplying" and the operating state is "on-hook" during the drive power supply stop period, the main device 1 drives the cordless telephone device 32 to the master unit BS2. The power supply hub device 2 can be controlled so as to stop the supply of electric power. As a result, even if the drive power supply to the master unit corresponding to the off-hook of the slave unit is resumed during the drive power supply stop period, the drive power supply is resumed when the use is completed. Can be stopped. Therefore, even if the supply of the drive power to the master unit of the cordless telephone device is resumed during the drive power supply stop period, the supply of the drive power is stopped when the cordless telephone device is no longer used. Therefore, it is possible to prevent the labor saving of power consumption from being hindered.

[Effect of Embodiment]
In the telephone system of this embodiment, the main device 1 controls the power supply hub device 2, so that the supply and stop of the drive power to the master unit of the cordless telephone device can be controlled for each connection port. In this way, the supply of the driving power to the cordless telephone device connected to the power supply hub device 2 can be stopped, so that the power consumption of the cordless telephone device can be saved to the maximum.

Further, among the plurality of cordless telephone devices connected to the power supply hub device 2, the master unit of one cordless telephone device is used as the power supply continuation master unit to continue the supply of drive power, and the master unit whose drive power supply is stopped. It has a configuration that can receive a power supply restart request from a slave unit corresponding to. As a result, when the slave unit corresponding to the master unit whose drive power supply is stopped is used, the target master unit is sent to the main unit 1 via the continuous power supply master unit. Since it is possible to request the resumption of the supply of the driving power of the cordless telephone device, it is possible to prevent the cordless telephone device from becoming completely inoperable.

As described above, in the telephone system of this embodiment, by stopping the supply of the driving power, the power consumption of the cordless telephone device can be reduced to the maximum, and the cordless telephone device cannot function. It does not occur.

[Modification example]
In the above-described embodiment, the case where one power supply hub device 2 is connected to the main device 1 to form a telephone system has been described as an example, but the present invention is not limited to this. In a telephone system configured by connecting a plurality of power feeding hub devices 2 in parallel to the main device 1, or in a telephone system configured by connecting a plurality of power feeding hub devices 2 in series. Also, the present invention can be applied.

In this way, when a large-scale telephone system is constructed by using a plurality of power supply hub devices 2, the supply / stop of drive power is controlled for each power supply hub device 2 and for each connection port. It should be. Further, when a large-scale telephone system is constructed by using a plurality of power supply hub devices 2, a plurality of power supply continuation master units are provided, and each of the plurality of power supply continuation master units is paired for power supply control. It suffices to set so that the slave units to be made are distributed.

Further, it is not necessary to pair the slave unit for power supply control with the power supply continuation master unit, and when the power supply continuation master unit receives the power supply restart request from the slave unit, it transfers this to the main unit 1. You may try to do it. In this case, when there are a plurality of power supply continuation master units, it is considered that a plurality of power supply continuation master units for the same master unit may be transmitted to the main unit 1 from different power supply continuation master units. However, in the main device 1, the earliest incoming power supply restart request may be adopted, and other power supply restart requests may be ignored.

In addition, when the supply of drive power to the power supply off master unit is stopped at the time of an incoming call, the drive power is supplied to each power supply off master unit so that the incoming call can be answered by each power supply off master unit. Supply may be restarted all at once. In this case, when an incoming call is answered by any of the cordless telephone devices, the supply of the drive power to the other power supply off master unit is stopped again. In addition, when the master unit of the cordless telephone device that answered the incoming call is the power supply off master unit, the supply of drive power to the power supply off master unit is also stopped when the call ends and the on-hook state is reached. You just have to control it. As a result, it is possible to answer an incoming call quickly, and it is possible to save labor in terms of power consumption of each cordless telephone device.
