Description

  The present invention relates to a key telephone system, and more particularly to a power saving type key telephone system.

  The power consumption per extension telephone in a conventional key telephone system is generally small during standby and large during a call, particularly during a speaker call, but is still about several watts. Although power consumption during standby is relatively low, power supply from the main device or power supply device to the extension telephone is generally continued for 24 hours. The power consumption per extension telephone is a category of low power consumption equipment, but if the number of extension telephones goes from several hundred to more than 1,000, the power consumption of the entire system reaches several kW, and other business equipment The power consumption is not negligible. Corresponding to the IP (Internet Protocol) of the external line that was started for the purpose of reducing the communication cost, the extension telephone of the key telephone system is becoming IP, and the internal telephone is also a high-speed LAN (Local Area) such as Ethernet (registered trademark). Network (local area network) interface LSI (Large Scale Integration) and high-speed control CPU (Central Processing Unit) are required, and power consumption is two to three times that of conventional key telephone systems. It is inevitable that power consumption will increase more and more as telephones are being developed not only as telephones for voice calls but also as information devices capable of video communication and Web browsing.

  On the other hand, some business devices such as FAX machines, printers, and copiers have power consumption of several hundred watts per unit during operation, but the power consumption is reduced to 10 W or less during standby. Is already mainstream.

  In addition, as seen in the increase in ISO14001 certified companies and green purchasing trends, environmental protection, resource saving and energy saving are now becoming common keywords to prevent global warming.

  As a method of reducing power consumption during nighttime and holidays in key telephone devices and digital button telephone devices from such a trend, power is automatically supplied from the main device to the key telephone when the unused time continues for a certain period of time. Has been proposed (see, for example, Patent Literature 1 and Patent Literature 2). In this case, even within the company where all employees left the company, normal operation is performed while waiting for unused time to continue for a certain period of time. It was. In addition, even if the power supply is automatically resumed when there is an incoming call, it is obvious that nobody responds at night or on holidays, and it is obvious that no one responds. There was a problem of repeating the operation of stopping the power supply after waiting for a certain period of time every time there is an incoming call.

  Further, in order to reduce power consumption in a time zone when the extension telephone is not used, a method of switching from the daytime mode to the nighttime mode by inputting a keyword from the extension telephone (for example, see Patent Document 3), even if there is an incoming call If there is no response within a certain period of time, a method has been proposed to reduce power consumption by switching from daytime mode to nighttime mode by determining that the person is unattended and stopping the extension telephone LCD display and LED display (for example, patents) Reference 4). In this case, even when the night mode is set, the LCD display and the LED display of the extension telephone are only stopped, the power supply to the extension telephone is not completely stopped, and the power saving effect is halfway. There was a problem of being.

  Further, when no extension / incoming call operation is performed on the extension telephone within a certain period of time, the standby mode is entered, and when all the extension telephones are in the standby mode, the power supply from the main unit to the extension telephone is stopped. A method has been proposed in which the apparatus itself shifts to the standby mode to reduce power consumption (see, for example, Patent Document 5). In this case, each extension telephone only shifts to the standby mode when no incoming / outgoing call operation is performed within a predetermined time, and power supply to the extension telephone is not completely stopped. The power supply to the extension telephones is stopped only after all the extension telephones have shifted to the standby mode. However, if there is an incoming call during that time, the standby mode is canceled, so the normal mode and the standby mode are repeated. Had a problem that the effect of reducing power consumption was halfway. In addition, if the same operation as that of an extension telephone is performed even when an incoming call is received by a FAX terminal, answering machine, or voice response device connected to a single telephone adapter for connecting a single telephone to the extension side, the normal mode is also set. There was a problem of repeating the standby mode.

  To suppress unnecessary power consumption, the operation mode is set when the user's ID card is connected to the key telephone, and the standby mode (non-operation mode) is set when the user ID card is not connected. When the ID card is disconnected, a method has been proposed in which the power consumption is reduced by switching to the night mode and stopping the power supply to the main device (for example, see Patent Document 6). In this case, if the user forgets to hold the ID card, the key telephone cannot be used at all. Even if the user holds the ID card, the ID card must be inserted into the key telephone or pulled out every time the user uses it. There was a problem that the operation was troublesome. In addition, if the ID card remains inserted in the key telephone because of the trouble, there is a problem that the power supply state continues as usual and the power consumption cannot be reduced at all.

  Similarly, in order to reduce power consumption in the entire system, when a telephone and a computer terminal are installed for each user, when the computer terminal shifts from the normal mode to the standby mode, the main apparatus switches to the key telephone. Have been proposed to reduce the power consumption by restarting the power supply when the power switch is stopped and the hook switch is in an off-hook state, for example, when it is in a use start state (for example, Patent Document 7, Patent Document). 8). In this case, it is effective when the computer terminal is turned on. However, when the computer terminal is turned off at night or on holidays, power supply to the key telephone is not continued as usual. There was a problem of not getting.

  In order to make it possible to use any of the key telephones even during a period when power supply is stopped, an extension interface unit that stops power supply during the power saving period and an extension interface unit that supplies power also during the power saving period A method for reducing power consumption has been proposed (see, for example, Patent Document 9). In this case, since the extension interface unit that stops power supply during the power saving period and the extension interface unit that continues power supply are fixed, the key telephone set that continues to supply power during the power saving period is fixedly specified. Since the key phone that can continue to be powered cannot be changed in the settings, there is a problem that its use is limited to emergency and emergency button phones, even though it is a specific key phone, power feeding continues as usual, There was a problem that the power saving effect was halfway.

  In order to provide a private branch exchange that can reduce power consumption without bothering the maintenance personnel, an operating time storage means is provided for each expansion rack on the basic rack, and the expansion rack is turned on only during the operation time period. Or a method for reducing power consumption by turning it off (see, for example, Patent Document 10). In this case, although there is a power saving effect of the extension rack, there has been a problem that the power saving effect of the basic rack and the extension telephone connected to the basic rack cannot be obtained at all.

  In order to provide a key telephone device that can reduce the power consumption of the entire system during times of low incoming frequencies, only the specified extension terminal such as a voice mail terminal can answer the incoming call while the night mode is set. When receiving, stop supplying power to other extension terminals, and when receiving an incoming call to a specific extension terminal, resume power supply to the other extension terminal, return to the normal waiting state, and wait for a certain period of time Then, the method of reducing power consumption by stopping an electric power supply again is proposed (for example, refer patent document 11). In this case, even if there is no attendance at night or on holidays, when a specific extension terminal receives an incoming call, power is resumed for all the other extension terminals. There was a problem that the power effect was reduced.

In the IP telephone system, in order to achieve effective power saving, in the standby state where there is no outgoing / incoming operation for a predetermined time or longer, the power to each part except for the LAN interface means, key operation detecting means, and timer means of the IP telephone terminal is reduced. It has a power saving mode to restrict, and when in the power saving mode, there is an incoming call, when a power mode switching packet is received through the LAN interface means, when a key operation input is detected, when an elapse of a predetermined time is detected, At any time, by providing a normal mode for supplying power to all parts, a method for periodically managing the presence or absence of connected IP telephone terminals while reducing power consumption has been proposed ( For example, see Patent Document 12). In this case, there is a problem that the power saving mode and the normal mode are repeated even when there is an incoming call even at night or on a holiday, or when the power saving mode and the normal mode are repeated every certain time. There was a problem that the power saving effect was halfway.

  The key telephone system according to the present invention is a system in which one or a plurality of lines are shared by a plurality of extension communication devices by call control of the key telephone main apparatus, and external line communication and extension communication are performed.

  The power supply stop period setting means 11 is a system component device such as an extension communication device, a line gateway, a key telephone main device, a call recording device, a three-party call device, a presence management device for managing presence / absence, or its internal configuration This is means for setting a power supply stop period for the circuit.

  The power supply intermittent circuit setting unit 12 includes a system component device that stops power supply during the period determined by the power supply stop period setting unit 11 or an internal component circuit thereof, and a system component device that continues without stopping power supply or an internal component circuit thereof. Is a means for setting in advance.

  The extension communication device power supply means 13 is a means for supplying power to the internal component circuit 21 of the extension communication device 2 or the system component device. The power supply means 15 for the circuit gateway circuit is a means for supplying power to the circuit gateway circuit 17 or the system component device.

  The power supply interruption means 14 for extension communication equipment is means for stopping / restarting power supply to the internal configuration circuit 21 of the extension communication equipment 2 or the system configuration equipment, or continuing power supply without stopping. Similarly, the power supply interruption means 16 for the line gateway circuit is means for stopping / resuming the power supply to the line gateway circuit 17 or the system component device or continuing the power supply without stopping.

  Extension communication devices 2-1 to 2-n are connected to the key telephone main apparatus 1 via power supply paths N1 to Nn, respectively. The line gateway circuits 17-1 to 17-n are connected via line gateway circuit power supply means 15-1 to 15-n, power supply paths M1 to Mn, and line gateway circuit power supply interrupting means 16-1 to 16-n. Power is supplied.

  The power supply stop period setting means 11 is provided with a power supply stop period setting table which will be described later as an example of setting the power supply stop period. In the power supply stop period setting table, for example, from 0:00 to 7:00 from Monday to Friday and from 21:00 to 24:00, from 0:00 to 24:00 on Saturdays, Sundays and holidays A power supply stop period is set to stop power supply. The power supply stop period setting unit 11 may be in a form of presetting a period during which power is supplied.

  The power supply intermittent circuit setting means 12 can provide a power supply stop release flag (or a constant power supply flag) for each extension communication device and each line gateway circuit, and selects a specific extension communication device and line gateway circuit to stop power supply. Can be released or power can be continued. Further, the power supply interrupting circuit setting means 12 can have a function of detecting that any of the extension communication devices has pressed the off-hook or speaker button, and any of the extension communication devices is off-hook or speaker while the power supply is stopped. When the button is pressed, it is possible to have a function of temporarily canceling the power supply stop to the extension communication device. In this case, the extension communication device is provided with a key that is separately connected to a power source and is turned off when the off-hook or speaker button is pressed on either or both of the hook switch and the speaker button switch. While making it possible to detect pressing, it is possible to eliminate power consumption when power supply is stopped.

Is done. When the set power supply stop period is exceeded, power supply to each of the extension communication devices 2-1 to 2-n and the line gateway circuits 17-1 to 17-n is started, and each of the extension communication devices 2-1 to 2-n and The circuit gateway circuits 17-1 to 17-n start normal operation. When the set power supply stop period is reached, power supply to each of the extension communication devices 2-1 to 2-n and the line gateway circuits 17-1 to 17-n is stopped, and a complete energy saving state is obtained. When the power supply period is set in the power supply stop period setting table, power is supplied to each of the extension communication devices 2-1 to 2-n and the line gateway circuits 17-1 to 17-n during the power supply period. In periods other than the period, power supply to the extension communication devices 2-1 to 2-n and the line gateway circuits 17-1 to 17-n is stopped.

  When there is an extension communication device or a line gateway circuit that needs to be supplied even during the power supply stop period, for example, the power supply interrupt circuit setting means 12 from any one of the extension communication devices 2-1 to 2-n. By setting the release flag provided in, the power supply suspension period for each extension communication device can be released. Cancellation of the power supply suspension period for the circuit gateway circuit can be set from the key telephone main device 1 or a specific extension communication device, and the power supply suspension period for each circuit gateway circuit 17-1 to 17-n is canceled. can do.

  The power supply stop period setting table provided in the power supply stop period setting means 11 can set the power supply stop period of the entire system. Further, the power supply stop period setting table can set different power supply stop periods for each extension communication device and line gateway circuit. In this case, the extension communication device and the line gateway circuit can be grouped, and a power supply stop period can be set for each group.

  A setting example such as a power supply stop period in the power supply stop period setting table provided in the power supply stop period setting means 11 in the key telephone system according to the present invention will be described with reference to FIGS. FIG. 2 is an example in which the user of each extension communication device is set by the power supply stop period setting method in the case where the flextime system and the rotary holiday system are adopted. In this example, the extension communication device circuit N1 is set to the power supply stop period from 15:00 to 6:00 on the following day, and Saturday and Sunday are set to the power supply stop period all day. Similarly, the extension communication device circuit N2 is set to the power supply stop period from 16:00 to 7:00 on the next day, and Sunday and Monday are set to the power supply stop period all day, and the extension communication device circuit N3 is set from 17:00 to 8:00 on the next day. During the power supply stop period, Monday and Tuesday are set as the all-day power supply stop period, and the extension communication device circuit N4 is set as the power supply stop period from 18:00 to 9:00 on the next day, and Tuesday and Wednesday are set as the all-day power supply stop period. In the communication device circuit N5, a power supply stop period is set from 19:00 to 10:00 on the next day, and Wednesday and Thursday are set as an all-day power supply stop period. The extension communication device circuit Nn is set to all-day power supply from 24:00 to 0:00 on the next day, that is, the power supply stop period is not set, and is set so as not to stop power supply for one week. Similarly to the extension communication equipment circuit, the analog line gateway circuit and the ISDN line gateway circuit are also set with a power supply stop period (time and day of the week) corresponding to the flextime system and specific analog line gateway circuit M1m and ISDN line The gateway circuit M2n is set to always supply power. Further, the power supply stop period is set for the IP line gateway circuit from 19:00 to 6:00 on the next day, and Saturday and Sunday are set for the power supply stop period all day. In this example, during the summer holiday period from August 12 to August 16, and from the year-end and New Year holiday period from December 29 to January 3, With the exception of the line gateway circuit and ISDN line gateway circuit, all the remaining extension communication equipment circuits, analog line gateway circuits, ISDN line gateway circuits, and IP line gateway circuits are powered off. According to this method, it is possible to arbitrarily select an extension communication device circuit, various line gateway circuits, and the like to stop power feeding, thereby achieving energy saving.

  The power supply stop period setting method shown in FIG. 3 is an example of resumption of power supply at any time that enables a call to be made by allowing the user to make and receive calls at any time from the extension communication device that is basically set to power supply stop in the power supply stop period. In this example, as occasional settings, when there is a power supply restart operation by off-hook etc. for each extension communication device circuit, power supply to the extension communication device circuit is restarted and power supply stop operation by on-hook etc. The power supply to the extension communication device circuit is set to stop. The analog line gateway circuit and the ISDN line gateway circuit are set to a constant power supply state in which at least one line continues to supply power. It is also possible to set power supply to be resumed when a request for resuming power supply from the extension communication equipment circuit set to stop power supply and a predetermined specific operation are performed, and to stop power supply after a predetermined time has elapsed. According to this method, energy saving can be achieved and transmission can be performed as needed even from an extension communication device set to stop feeding.

  The power supply stop period setting method shown in FIG. 4 is an example in which the power supply stop period setting method shown in FIG. In the example of FIG. 3, the extension communication device circuits Nn-1 and Nn whose basic setting is always power supply are also set to the power supply stop in this example, the power supply is resumed by the off-hook setting at any time and the power supply is stopped by the on-hook.
