Description

  The present invention relates to a power saving method and apparatus that suppresses power consumption of a button telephone device in conjunction with an operating state of a security monitoring apparatus. When the security monitoring device is operating, it is judged that the monitoring area is unattended, and in order to suppress the power consumption of the key telephone device, the power supply to the key telephone device is stopped to significantly reduce the power consumption. The present invention provides a power saving method and apparatus that enable the above.

  In Patent Document 1, by operating the first telephone of a plurality of telephones, two or more telephones not including this first telephone are collectively set to be absent, and further, by stopping power supply, Power consumption is reduced while the telephone is not necessary (Patent Document 1, Paragraph 0008).

In Patent Document 2, when the unused state of the computer terminal continues for a predetermined period, the operation state shifts from the normal mode to the standby mode, and in that case, power supply to the telephone associated with the computer terminal is stopped. (Patent Document 2, paragraphs 0004 and 0005).

According to Patent Document 3, a personal computer is equipped with a battery, so that the home security system can be operated even in the event of a power failure, and when there is no visitor, only the infrared sensor needs to be operated, thereby enhancing the power saving effect (patent Reference 3, paragraphs 0022, 0023).

Analyzing conventional power consumption suppression systems can be classified into the following power-saving types.
Power saving type 1: The telephone operator is operated to reduce the power consumption of the telephone device (Patent Document 1).
Power saving type 2: The power consumption of the telephone device is reduced by detecting that the telephone device or a device related thereto is not operated for a predetermined period of time (Patent Document 2).
Power-saving type 3: Infrared sensors detect humans and reduce system power consumption when no humans are present (Patent Document 3).

  A button telephone device installed in an office or the like normally operates for 24 hours without being turned off. Even when the office is unattended, power is often supplied to the key telephone device for the purpose of maintaining the answering function of the key telephone device. In many cases, power is continuously supplied to a button telephone terminal constituting the button telephone apparatus even though the button telephone terminal is not operated in an unattended state. Based on the information that the office has become unattended, it is desired to reliably reduce the power consumption of the key telephone device.

  In the power saving type 1, since the telephone operator is operated to reduce the power consumption of the telephone device, the power consumption cannot be suppressed if this operation is forgotten. The place where the telephone device is installed is often a closed space such as a room, and a security monitoring device may be installed in the closed space because of the necessity for crime prevention and disaster prevention. In such a closed space, when many people are working using many key telephone terminals, there is a problem to be solved that the final worker is burdened with a power saving operation. there were.

  In the power saving type 2, the power consumption of the telephone device is reduced by detecting that the telephone terminal or the device related thereto is not operated for a predetermined period. In this type, there is a problem to be solved in that even when the telephone terminal is not used, power for displaying a clock or a line usage state is consumed in each telephone terminal.

  In the power-saving type 3, humans are detected by an infrared sensor or the like, and the power consumption of the system is reduced when no one is present. Therefore, the sensitivity or accuracy of human detection is not sufficient. There remains a problem to be solved that operates sensitively to the need and cannot expect much power saving effect.

  If the key telephone device has an answering machine function, it is necessary to leave this function to be utilized even when the power is reduced during unattended, and whether to maintain this function when manned. It was desired to be selectable by instruction.

As a means of detecting that a closed space such as an office where many key phone terminals are installed has become unattended, it operates automatically when a person becomes unattended or by a human operation that finally leaves the closed space. A security monitoring device was used. Therefore,
When the operation of the security monitoring device is in an off state, terminal power supply control means for outputting a power supply control signal to supply power to many button telephone terminals,
Including an extension circuit means for receiving the power supply control signal, exchanging calls and control signals to many key telephone terminals, and supplying power necessary for the telephone telephone terminal's telephone call operation;
A power saving device for a button phone was constructed. In the case of having an answering machine function, the function is maintained even when the operation of the security monitoring device is in an on state, that is, unattended.

  When the operation of the security monitoring device is in the on state, since there is no person such as an operator in the monitoring area, the key telephone terminal does not need to be operating and power is not supplied to the key telephone terminal. That is, when the security monitoring device is operated, it is determined that the monitoring area such as the office has become unattended, and the power supply to the key telephone terminal is automatically stopped, so no operation on the key telephone device is required. Transition to the power saving state. Even in the power saving state, since the answering machine function is retained, the recording or playback function from the local line in the unattended state is maintained.

  When the operation of the security monitoring apparatus is in an off state, there are humans such as workers in the monitoring area, and it is necessary to supply power to many key telephone terminals. Therefore, since power is supplied to the key telephone terminal when the operation of the security monitoring apparatus is in the off state, a high power saving effect can be obtained with certainty without burdening the operator with the operation.

FIG. 1 is a circuit configuration diagram showing an embodiment of a power saving apparatus for a button telephone according to the present invention. (Example 1) FIG. 2 is a circuit configuration diagram showing another embodiment of the power saving apparatus for a button telephone according to the present invention. (Example 2) FIG. 3 is a flowchart showing an operation flow of the power saving apparatus for the button telephone according to the present invention shown in FIGS. 1 and 2. FIG. 4 is a flowchart showing an operation flow of the power saving apparatus for the button telephone according to the present invention shown in FIGS. 1 and 2 together with FIG.

  When the operation of the security monitoring device is in the on state, there is no human being such as an operator in the monitoring area, so the key telephone terminal does not need to be operated and it is not necessary to supply power to the key telephone terminal. . When the operation of the security monitoring apparatus is in an off state, there are humans such as workers in the monitoring area, and it is necessary to supply power to many key telephone terminals. Therefore, since power is supplied to the key telephone terminal when the operation of the security monitoring device is in the off state, a high power saving effect can be obtained without placing a burden on the power saving operation on the operator. became.

  FIG. 1 is a circuit configuration diagram showing an embodiment of a power saving apparatus for a button telephone according to the present invention (Embodiment 1). The security monitoring device 1 is provided for the necessity of crime prevention and disaster prevention. For example, it captures infrared rays emitted by humans, detects human movements by reflection of infrared rays, or shoots images of security monitoring areas. Sensors and cameras. The security monitoring device 1 is applied with the operation on / off instruction signal 3 or operates with the power switch turned on, and outputs an operation on / off state monitoring signal 4 representing the operation state. The operation on / off state monitoring signal 4 is applied to the key telephone main device 10.

  The key telephone main device 10 includes a security operation monitoring unit 11, a control unit 12, a call exchange unit 13, a station line circuit 14A-D, a recording / playback circuit 15, a transmission control unit 16, an extension circuit 31A-N, and a terminal power supply control circuit. 33 are included. A key telephone terminal 36A-N is connected to each extension circuit 31A-N via a terminal line 41A-N, and a telephone call and a control signal are exchanged. Each extension circuit 31A-N supplies power necessary for the operation of the key telephone terminal 36A-N via the terminal line 41A-N.

  The operation on / off state monitoring signal 4 is applied to the security operation monitoring unit 11 of the key telephone main device 10. The security operation monitoring unit 11 receives the operation on / off state monitoring signal 4 representing the on / off state of the security monitoring device 1, monitors the on / off state of the security operation, and outputs the monitoring signal 21 representing the on / off state. The control unit 12 receives the monitoring signal 21 and outputs a security state signal 22 for transmitting the on / off state of the security operation.

  The control unit 12 controls the normal operation state of the conventional key telephone main unit, that is, the key telephone terminals 36A-N with respect to the call exchange unit 13, the office line circuit 14A-D, the recording / playback circuit 15, and the transmission control unit 16. Since the normal control is the same as the control in the state where the power supply is not stopped, the security state signal 22 includes this normal control signal. When the power supply to the key telephone terminal 36A-N is stopped, the control unit 12 is programmed not to regard this as a failure, although it cannot communicate with the key telephone terminal 36A-N.

  In a normal power supply state to the button telephone terminal 36A-N, communication between the office line 5A-D and the button telephone terminal 36A-N is performed by the office line circuit 14A-D, the signal line 24A-D, and the call exchange unit. 13, the signal line 23, the transmission control unit 16, the signal line 26 </ b> A-N, the extension circuit 31 </ b> A-N, and the terminal line 41 </ b> A-N are the same as the operation of the conventional key telephone main unit. Therefore, the description of communication between the office line 5A-D and the key telephone terminal 36A-N is omitted.

  The terminal power supply control circuit 33 receives the security state signal 22 and outputs a power supply control signal 44 to supply power to the key telephone terminals 36A-N in the off state of the security operation. Under the control of the power supply control signal 44, the extension circuit 31A-N supplies necessary power to the key telephone terminal 36A-N in the normal operation state in the security operation off state, and the button telephone in the security operation on state. The power supply to the terminals 36A-N is stopped. The recording / playback circuit 15 is connected to the call exchange unit 13 that does not receive power supply stop by the signal line 25, and does not receive power supply stop even when the security operation is on, so that the recording / playback of the call from the office line 5A-D can be performed. An answering machine function can be fulfilled. When the security operation is off, it is programmed so that whether or not the answering function is activated can be selected by the operation of the operator.

  FIG. 2 is a circuit configuration diagram showing another embodiment of the power saving apparatus for a button telephone according to the present invention (Embodiment 2). The difference from FIG. 1 is that the operation on / off instruction signal 3 is directly applied to the control unit 12B. That is, the control means 12B receives the operation on / off instruction signal 3 for instructing the security monitoring operation, and outputs the security state signal 22 for transmitting the on / off state of the security operation. Other operations are the same as those of the first embodiment shown in FIG.

  FIG. 3 is a flowchart showing an operation flow of the power saving apparatus for the button telephone according to the present invention shown in FIGS. 1 and 2. The power saving processing operation starts. The key telephone main device 10 is monitoring the on / off state of the security monitoring device 1 (S1 in FIG. 3). If the monitoring area of the security monitoring device 1 is, for example, a closed space such as an office, the security monitoring device 1 is in an on state (no human presence state) when there is no human being, and monitoring is performed. If so, the security monitoring device 1 enters an off state (human presence state) and stops operating.

  When the on state (no human presence state) is detected (S2 on), the operation of the answering machine function (recording / playback circuit 15) is started (S3). The control units 12 and 12B stop the communication with the key telephone terminal 36A-N (S4), stop the power supply to the key telephone terminal 36A-N (S5), and end the power saving processing operation. By this communication stop (S4) step, the control units 12 and 12B can distinguish the communication stop state with the key telephone terminal 36A-N due to the power supply stop (S5) from the communication stop state due to failure. It is not recorded as an error, and it is not erroneously determined that a failure has occurred. In step S2, when the control units 12 and 12B detect that the on / off state of the security monitoring device 1 is the off state (human presence state) (S2 off), the power supply restart process (S11-14) is entered (S7).

  FIG. 4 is a flowchart showing the operation flow of the power saving apparatus for the button telephone according to the present invention shown in FIGS. 1 and 2 together with FIG. 3, and shows the contents of the power supply restart process shown in FIG. When power supply restart processing is entered, power supply to the key telephone terminals 36A-N is restarted (S11). Thereby, the control parts 12 and 12B can restart communication with the key telephone terminal 36A-N (S12). If the on / off state of the security monitoring device 1 is in the off state (human presence state), since the answering function is not required in many cases, the operation of the answering function is stopped (S13, S14). However, since the answering machine function may be required even in the off state (human presence state), the operation of the answering machine function may not be stopped by the operation in that case (S13 is not performed). Is programmed.

  As apparent from the gist of the present invention, the type of security monitoring device is not limited, but can be applied to interlocking operations with all types of security monitoring devices that can reliably indicate the presence or absence of a person in the monitoring area. it can.
