Description

  The present invention relates to a communication system and a control method for controlling communication of a telephone, and more particularly to line disconnection control.

  Generally, in a communication apparatus in which one telephone line is accommodated and a plurality of telephones are connected, when one telephone uses a telephone line, use of the telephone line by another telephone is limited. Therefore, when one telephone is using a telephone line and another telephone uses a telephone line, it is necessary to forcibly disconnect the telephone line currently used.

  In order to determine forcible disconnection, for example, when a personal identification number is set in the system data of the device and the personal identification number is added to the telephone number to be transmitted, even if another telephone is using the telephone line. The telephone line is forcibly disconnected. In addition, if a phone number to be forcibly disconnected is registered in advance in the device database and a call is made from a telephone, if the other telephone is using the telephone line, the telephone number that was sent with reference to that database is forcibly disconnected. Determine whether the phone number you want to use. If the outgoing telephone number is a telephone number to be forcibly disconnected, the telephone line currently in use is forcibly disconnected.

  On the other hand, in Patent Document 1, in the case where all the communication lines are in use and the other party's telephone number of the telephone requesting the call is an emergency contact registered in advance, the currently used line is forcibly disconnected and the emergency contact is made It is described that the call is made first. In addition, in Patent Document 2, for example, when an emergency notification device for reporting a fire or the like is received, a channel that is currently in use is disconnected to create a free channel, and a scheduled telephone number is notified. It is described. Further, Patent Document 3 describes that a regular notification is made that an emergency call device for reporting a fire, a gas leak or the like is normal.

Japanese Patent Laid-Open No. 07-107206 JP 2001-94683 A JP 2004-14780 A

  As described above, when one telephone is using a telephone line and another telephone uses a telephone line, it is necessary to forcibly disconnect the telephone line that is currently in use. In order to do this, for example, it is necessary to register in the apparatus in advance such as registering the telephone number to be forcibly disconnected in the database.

  In addition, in the above-described normal technique, Patent Document 1 describes that in the case of an emergency contact whose destination telephone number is registered in advance, the currently used line is forcibly disconnected and the emergency contact is called. Patent Document 2 describes that when a call is made from an emergency call machine, the line is forcibly disconnected and a scheduled telephone number is notified.

  On the other hand, Patent Document 3 describes that an emergency call device for reporting a fire, a gas leak, etc. is informed on a regular basis, but in the normal technique, the emergency call described in Patent Document 3 etc. When an emergency call is made from a machine, it is possible to forcibly disconnect the line and make a call from the emergency call machine, but the line is also used for non-urgent calls such as scheduled reports from the emergency call machine. There was a problem that forced cutting.

It is a block diagram which shows 2nd Embodiment of the communication system of this invention.

  Next, embodiments for carrying out the invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a first embodiment of a communication system according to the present invention. In the figure, reference numeral 100 denotes a communication device for performing communication control, to which a telephone set A110 and a telephone set B120 are connected. In FIG. 1, a telephone A110 and a telephone B120 are representatively shown, but two or more telephones are connected to the communication apparatus 100. The communication device 100 has a function of a telephone exchange.

  The communication apparatus 100 accommodates (connects) at least one telephone line 150. As described later, the communication device 100 forcibly disconnects the telephone line and makes a priority call when a telephone call is given priority by a non-voltage contact (not shown) even when all telephone lines are in use. Take control. This will be described in detail later. For example, it is assumed that the telephone A110 is a telephone that is given priority by no-voltage contact, and that the telephone B120 is currently in a call using the telephone line 150. At this time, if there is a call from the telephone set A110, the telephone line 150 currently being used by the telephone set B120 is forcibly disconnected, and the call from the telephone set A110 is preferentially called to the telephone set B120.

  The telephone A 110 and the telephone B 120 make and receive calls with an external telephone through the telephone line 150 under the control of the communication device 100. Sensor A 130 and sensor B 140 are switches connected to a non-voltage contact inside communication device 100, and are provided corresponding to telephone set A 110 and telephone set B 120, respectively. A sensor connected to the no-voltage contact corresponding to the telephone A110 is A130, and a sensor connected to the no-voltage contact corresponding to the telephone B120 is B140.

  In this specification, A130 and B140 are called sensors, but they are switches for setting the line priority use of the corresponding telephone by turning on or off from the outside. Priorities are determined for the sensor A 130 and the sensor B 140. For example, the sensor A 130 has a higher priority than the sensor B 140.

  Although not shown in FIG. 1, the non-voltage contact is a contact for setting telephone line preferential use provided inside the communication apparatus 100 corresponding to each of a plurality of telephones. For example, when the sensor A 130 shown in FIG. 1 is turned on, the corresponding no-voltage contact is set on, and the priority use of the telephone line 150 of the telephone A 110 corresponding to the sensor A 130 is set. For this reason, the communication device 100 forcibly disconnects the telephone line even when all telephone lines are in use when a call is made from a telephone that has priority with no-voltage contact, and gives priority to a call request from a telephone that has priority with a non-voltage contact. Control to place a call.

  Specifically, as shown in FIG. 1, sensor A130 and sensor B140 are connected to communication apparatus 100, and sensor A130 and sensor B140 are provided corresponding to telephone set A110 and telephone set B120, respectively. For example, when the sensor A130 corresponding to the telephone A110 is turned on, the telephone line priority of the telephone A110 is set, and the telephone line is forcibly disconnected even when all the telephone lines are in use, and the outgoing call request from the telephone A110 is prioritized. To control.

Next, a specific operation of the present embodiment will be described. In the following operation description,
(1) Example of forced disconnection of telephone A110 by telephone B120 (2) Example of forced disconnection of telephone B120 by telephone A110 (3) Example of not forcibly disconnecting telephone A110 in use when urgent calls overlap (4) An example of forced disconnection during use of the telephone set B120 when urgent calls overlap will be described. In this example, for example, the sensor A 130 has a higher priority than the sensor B 140 (that is, the telephone A 110 has a higher priority for using the line than the telephone B 120).

  2 and 3 are diagrams showing an example of forced disconnection of the telephone A110 by the telephone B120 of (1). FIG. 2 is a sequence diagram in that case, and FIG. 3 is a flowchart. As shown in FIG. 2, it is assumed that the telephone A 110 is currently in a call using the telephone line 150. During the telephone call of the telephone A110, the sensor B140 is set on and the sensor A130 is turned off. In this state, when the telephone B 120 is off-hooked, the processing of FIG. 3 is started, and a control circuit (not shown) in the communication apparatus 100 performs the following processing to determine whether the telephone A 110 is in use (see FIG. 3). S01 in FIG.

  If the telephone A110 is in use, it is determined whether the sensor B140 is on (S02). If the sensor B140 is on, it is determined whether the sensor A130 having a higher priority is on (S03). ). At this time, since the sensor A130 is off (S03 is N), the telephone A110 is busy (S04), and the telephone line 150 currently in use is forcibly disconnected and released (S05). The busy process is a process for terminating a call.

  That is, since the sensor A 130 is off, use of the telephone line of the telephone A 110 is not an urgent call, and since the sensor B 140 is on, it is determined that use of the telephone line of the telephone B 120 is urgent. After that, the telephone B 120 waits for dialing, and after receiving the dial from the telephone B 120, the telephone B 120 can make a call with an external telephone using the telephone line 150. On the other hand, when the sensor B140 is off at S02 (S02 is N), and when the sensor A130 is on at S03 (Y at S03), the telephone set B120 is busy.

  Next, an example of forced disconnection of the telephone B120 by the telephone A110 in (2) will be described. FIG. 4 is a sequence diagram in that case, and FIG. 5 is a flowchart. As shown in FIG. 4, it is assumed that the telephone set B120 is currently in a call using the telephone line 150. During this call, the sensor A 130 is set on and the sensor B 140 is turned off.

  In this state, when the telephone A110 is off-hooked, the processing of FIG. 5 is started, and a control circuit (not shown) in the communication apparatus 100 (not shown) determines whether the telephone B120 is in use (S07). If the telephone set B120 is in use, it is determined whether the sensor A130 is on (S08). If the sensor A 130 is on, the telephone B 120 is busy processed (S09), and the telephone line 150 currently in use is forcibly disconnected and released (S10).

  That is, since the sensor A 130 having a higher priority is on, the use of the line of the telephone A110 is given priority regardless of whether the telephone line of the telephone B120 is used for a normal call or an emergency call. In FIG. 3, the process advances from S02 to S03 to determine whether or not the sensor A 130 is on. In FIG. 5, there is no step corresponding to S03, and the process advances directly from S08 to S09. This is because the priority order of the sensor A 130 is higher than the priority order of the sensor B 140 in the example of FIG.

  Thereafter, the telephone set A110 waits for dialing, and after receiving the dial from the telephone set A110, it is possible to make a call with an external telephone using the telephone line 150. When the sensor A 130 is off in S08 (S08 is N), the telephone set A110 is busy.

  Next, an example will be described in which the emergency call of (3) is overlapped (when sensor A and sensor B are turned on at the same time) and the phone A110 is not forcibly disconnected during use. In this example, it is assumed that the telephone A110 having a higher priority is using the line first. FIG. 6 is a sequence diagram in that case. This will be described with reference to FIGS. Assume that the telephone set A110 is busy using the telephone line 150 as shown in FIG. At this time, the sensor A130 is set to ON, and the call by the telephone set A110 is an urgent call. Assume that sensor B140 is set to ON during this call.

  In this state, when the telephone set B120 is off-hooked, the processing of FIG. 3 is started, and a control circuit (not shown) determines whether the telephone set A110 is in use (S01). When the telephone A110 is in use, it is determined whether the sensor B140 is on (S02), and when the sensor B140 is on (S02 is Y), it is determined whether the sensor A130 is on (S03).

  At that time, since the sensor A130 is on (S03 is Y), the use of the telephone line of the telephone A110 and the outgoing call from the telephone B120 are urgent, but since the priority of the sensor A130 is high as described above, the telephone A110 Prioritize the use of the line. Therefore, the busy process of the telephone B 120 is performed, and the telephone A 110 subsequently makes a call using the telephone line 150.

  Next, an example of forced disconnection during use of the telephone B120 when there is an overlap of emergency calls (4) (that is, when the sensors are turned on simultaneously) will be described. In this example, it is assumed that the telephone B120 having a lower priority is using the line first. FIG. 7 is a sequence diagram in that case. This will be described with reference to FIGS. Now, as shown in FIG. 7, it is assumed that the telephone set B 120 is busy using the telephone line 150.

  The sensor B140 is set to ON, and the telephone call of the telephone set B120 is an emergency call. Assume that the sensor A 130 is turned on during this call. In this state, when the off-hook of the telephone A110 is detected, the process of FIG. 5 is started, and a control circuit (not shown) determines whether the telephone B120 is in use (S07).

  If the telephone B120 is in use, it is determined whether the sensor A130 is on (S08). When the sensor A 130 is on, the telephone A 110 has a higher priority than the telephone B 120, and therefore the telephone line usage of the telephone A 110 is given priority regardless of whether the telephone line use of the telephone B 120 is normal or urgent. . Therefore, the busy process of the telephone B120 is performed (S09), and the telephone line 150 is disconnected and released (S10).

  Thereafter, the telephone set A110 waits for dialing, and after receiving the dial from the telephone set A110, the telephone set A110 can make a call using the telephone line 150. If the sensor A 130 is off in S08 (S08 is N), the telephone set A110 is busy.

  In this embodiment, even when all the telephone lines are in use, when there is a call request from a telephone that is given priority by a non-voltage contact, the line is forcibly disconnected and control is made so that the call is issued with priority. It is possible to make a reliable call when making a call. In addition, it is possible to easily set the line priority use of the telephone by turning the switch on and off, so there is no need to change the device settings when changing / adding the telephone number for line priority use, etc., reducing the number of maintenance. It becomes possible.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. FIG. 8 is a block diagram showing the configuration of the second exemplary embodiment of the present invention. In FIG. 8, the same parts as those in FIG. In the first embodiment, an example of setting the telephone line priority use of a non-voltage contact by turning on / off an external switch has been described. However, in the second embodiment, the communication apparatus 100 is notified of a fire, a gas leak, or the like. An example will be described in which when an emergency call device 160 is connected and an emergency call is made from the emergency call device 160, the emergency call is preferentially called even when all the lines are in use. In the present embodiment, it is assumed that the non-voltage contact in the communication device 100 moves in conjunction with the emergency notification contact of the emergency notification device 160 connected to the communication device 100.

  For example, it is assumed that the emergency notification device 160 described in Patent Document 3 is connected to the communication device 100. A telephone set A110 and a telephone set B120 are also connected to the communication apparatus 100. The configuration is the same as that shown in FIG. 1 except that the emergency call device 160 is connected. As shown in FIG. 8, at least one telephone line 150 is connected to the communication device 100. The no-voltage contact of this embodiment is the same as the no-voltage contact described in the first embodiment, and the no-voltage contact in the communication device 100 is provided corresponding to each telephone and the emergency call device.

  The emergency call device 160 has an emergency call contact that is turned on or off at the time of an emergency call. For example, this contact point is turned on in the case of an emergency call. When the contact of the emergency call device 160 is turned on (for example, a fire or a gas leak occurs), the corresponding non-voltage contact in the communication device 100 is turned on and an emergency call is transmitted from the emergency call device 160 In other words, the communication device 100 performs control so that the emergency call of the emergency call device 160 is preferentially called by disconnecting the telephone line even when all the telephone lines are in use.

  Further, the emergency call device 160 has a plurality of contacts, and among them, there are contacts that have urgency and contacts that do not have urgency. For example, a contact that reports a fire, a gas leak, or the like is urgent, and a contact that reports a battery voltage drop or a scheduled report is not urgent. The no-voltage contact of the communication device 100 operates in conjunction only when the emergency contact of the emergency call device 160 is turned on, and the no-voltage contact of the communication device 100 when the non-urgent contact is turned on. The contact does not work.

  Therefore, the no-voltage contact of the communication device 100 operates in conjunction only when the contact with urgency is turned on, so that even when all the telephone lines are in use, the telephone line is disconnected to give priority to an emergency call. Take control. At that time, for example, an emergency call is transmitted from the emergency call device 160 to a predetermined contact address.

  In this configuration, since the no-voltage contact of the communication device 100 operates in conjunction with the emergency call contact of the emergency call device 160, it is possible to make an emergency call by forcibly disconnecting the line even when all lines are in use. . In addition, when the contact of the emergency call device 160 is not turned on, the no-voltage contact is not operated and a normal operation is performed. Therefore, the line is not forcibly disconnected for outgoing calls that are not urgent.

  As described above, in the present embodiment, when an emergency call is made from the emergency call device 160, the emergency call from the emergency call device can be preferentially called by forcibly disconnecting the line even when all the lines are in use. . Furthermore, since priority calls are made only for emergency calls with urgency, the line is not forcibly disconnected for non-urgent calls.

(Third embodiment)
Next, a third embodiment of the present invention will be described. The configuration of this embodiment is the same as that shown in FIG. 8, and as shown in FIG. 8, an emergency notification device 160 that similarly detects and reports a fire or gas leak is connected to the communication device 100. A110 and telephone set B120 are connected. The communication apparatus 100 is connected to at least one telephone line 150 except that the emergency call apparatus 160 is connected.

  In the second embodiment, the non-voltage contact in the communication device 100 operates in conjunction with the emergency call contact of the emergency call device 160 when an emergency call is made from the emergency call device 160, whereas the third embodiment In the embodiment, the third embodiment is different from the second embodiment in that an emergency call is transmitted by operating a non-voltage contact in the communication device 100 in the case of an emergency call from the emergency call device 160. As described with reference to FIG. 1 and the like, the no-voltage contact is provided corresponding to each telephone or emergency call device. An example of the emergency notification device 160 is described in Patent Document 3 and the like.

  In the present embodiment, since the emergency call device 160 operates the non-voltage contact in the communication device 100 to make a call when an emergency call is made, when the emergency call is sent from the emergency call device 160 to the communication device 100, the communication device The no-voltage contact corresponding to the emergency call device 160 in 100 operates. For this reason, when an emergency call is transmitted from the emergency call device 160, the communication device 100 performs control so that the telephone line is forcibly disconnected even when all of the telephone lines are in use, and a call request from the non-information notification device 160 is preferentially called. Do. At that time, for example, an emergency call is transmitted from the emergency call device 160 to a predetermined contact address.

  Further, the emergency call device 160 sends a report having urgency and a report having no urgency. For example, fires and gas leaks are urgent, and battery voltage drops and scheduled notifications are not urgent. The emergency call device 160 operates the non-voltage contact corresponding to that of the communication device 100 only when sending a notification having urgency, and does not operate the corresponding non-voltage contact in the case of a notification having no urgency.

  Therefore, when an urgent report is sent from the emergency call device 160, a corresponding non-voltage contact is operated, and the communication device 100 forcibly disconnects the telephone line even when all the telephone lines are in use, from the non-information notification device 160. The emergency call is controlled so as to make a priority call. On the other hand, when a non-urgent notification is transmitted from the emergency notification device 160, the corresponding non-voltage contact does not operate, so the communication device 100 performs a normal operation.

  In this configuration, since the emergency call device 160 operates the non-voltage contact corresponding to the emergency call, when the emergency call is transmitted from the emergency call device 160, the corresponding non-voltage contact operates. Even if all the lines are in use, the line can be forcibly disconnected and an emergency call can be made. In addition, when a non-urgent report such as a scheduled report for confirming that the battery voltage drop or the reporting device is normal is transmitted from the emergency reporting device 160, the no-voltage contact does not operate. Perform the action. Therefore, the line is not forcibly disconnected for outgoing calls that are not urgent.

  As described above, also in this embodiment, when an emergency call is made from the emergency call device 160, the emergency call from the emergency call device can be preferentially called by forcibly disconnecting the line even when all the lines are in use. it can. Furthermore, since priority calls are made only for emergency calls with urgency, the line is not forcibly disconnected for non-urgent calls.

  In the above embodiment, two telephones are connected to the communication apparatus 100, but three or more telephones may be connected. Further, although one telephone line is connected to the communication device 100, more telephone lines may be connected. Further, in FIG. 1, the sensor (switch) is not necessarily required for all telephones, that is, the line priority use of the telephone is set by providing the sensor only in the telephone for which priority use is set and turning on the sensor. The telephone set that does not set the priority use may not be provided with a sensor. In this case, the telephone sensor that does not set the line preferential use is handled as being off. Furthermore, in the above embodiment, an example in which a non-voltage contact is used as a contact for setting the preferential use of a line is shown, but a voltage contact may be used.

  The communication system of the above embodiment can be realized by hardware, but can also be realized by reading and executing a program for causing a computer to function as the communication system from a computer-readable recording medium. The control method of the communication system of the above embodiment can be realized by hardware, but is also realized by reading and executing a program for causing a computer to execute the method from a computer-readable recording medium. it can.
