Description

  The present invention relates to an improvement of a private branch exchange apparatus that is installed in a building or business office used by a single company or organization and that allows persons who perform business in the office to talk to each other. In particular, the present invention relates to connection control when an emergency situation occurs and a connection to a specific line (eg, 119, 110) and a notification are made via a private branch exchange. In particular, when a call is returned from a specific line after a report has been made, not only the reporter but also the related parties can intercept the conversation for the report at the same time and grasp the situation regarding the emergency situation. It relates to improvements to make it possible.

  Private telephone exchange devices are widely used in offices, factories, etc., for internal employees to communicate with each other. Private telephone exchange equipment is used to connect telephone lines wired to multiple locations belonging to a single office to make calls, and to install a loudspeaker on a desk phone or a telephone used on a wall. Devices capable of simultaneous communication and calling are also widely used. In general, a private branch exchange is connected to a telephone network operated by NTT or another telephone company, an extension telephone belonging to the private branch telephone exchange issues a connection request to the line of the telephone network, and a call is made to the line belonging to the telephone network. There are many forms that are configured and operated so as to be able to. Therefore, an emergency call can be made directly from an extension telephone to a specific line (eg, 110, 119) belonging to the telephone network.

  When a device provided in the police or fire department or the like corresponding to the specific line (eg, 110, 119) is contacted through the specific line, the person who made the first telephone contact places the handset. Even if the telephone line is disconnected due to, for example, the connection is forcibly put on hold or the connection contents are automatically memorized. A device is provided that sends a bell current to the telephone of the person who made the telephone call so that the telephone call can be made again. And when it is possible to make another call, the police or the fire department can ask further questions or make arrangements regarding the emergency situation. Yes. In principle, private branch exchanges are also equipped with a function that responds in conjunction with this. The telephone line of the private branch exchange that made the first call to the police or the fire department is called by the police or the fire department. It is set so that a return connection can be made.

  Here, the “private telephone exchange device” in this specification is not limited in scale or type. Further, the “private telephone exchange device” includes a device called a “key telephone system” or an exchange device equipped in a device called a “business phone”. This "private telephone exchange apparatus" is an apparatus having a function of connecting an extension line connected to the private telephone exchange apparatus to a public communication line operated by NTT or other telephone companies in accordance with the connection request. This “private telephone exchange device” is not limited to one centralized location, but when it is physically distributed (eg, headquarters, factory, sales office, etc.) at multiple remote locations. In addition, a configuration that can be used as one private branch exchange is also included.

  In [Patent Document 1] below, when an emergency call is made from a local telephone (for example, 119 is dialed), the content of the call is monitored from a specific telephone (for example, the telephone of the safety manager). Techniques that can be described are described. That is, this content corresponds to the prior art of the present invention. However, when an emergency call is made and a call is returned, there is no description relating to a technique for monitoring the contents of a telephone that does not respond to the call.

  [Patent Document 2] below describes a function for determining that an emergency call has been made from an extension telephone (paragraph [0016]).

  [Patent Document 3] below discloses a technique for intercepting a call on another line using an extension telephone (paragraph [0039]).

  [Patent Document 4] below discloses a technique for determining that it is an emergency call from a connection request number (paragraph [0014]).

  [Patent Document 5] below describes that an incoming call is identified as a call back from an emergency call destination (paragraph [0011]).

  In general, the larger the scale of the establishment for emergency communication as described above, the more likely that the person working there will pass the time without knowing anything about the occurrence of the emergency. Even if there is a person who can voluntarily cooperate with the emergency in some way, it cannot cooperate without knowing the occurrence of the emergency. In general, it is impossible to expect that an emergency will occur and that the person who has contacted it or the person in charge of the emergency will immediately contact the other departments in the company as information. is there. The person in charge who has been contacted will prioritize measures to respond directly to the emergency, and preventive communication will be completed after the response measures have been completed. Even if the damage spreads and the evacuation order is issued to many people, understand the outline of what is happening to those who evacuate. It is considered that the speed of evacuation and the situation of damage differ depending on whether the person is present or not completely understood.

  The present invention is a device for dealing with such a situation, and it is possible to notify a person who is in the range of using one on-premise telephone device such as the same office, or a part of them to a telephone contact accompanying the occurrence of an emergency. An object of the present invention is to provide a device that can intercept the contents without taking up the receiver. The present invention is used when a situation requiring an emergency occurs in one office and the fire department or the police arrives at the office after taking an appropriate action after contacting the fire department or the police. The goal is to make it easier for many of the staff at the offices to already know the outline of the situation and to cooperate with the fire department and the police. An object of this invention is to provide the apparatus which can improve the product power as a private branch exchange apparatus.

  The present invention is a private branch exchange, and when an emergency call is made from one of the extension lines accommodated in the private branch exchange to a police or a fire department (eg, 110, 119), etc. There is a response from the police or fire department that accepted the call. The answering communication and the subsequent conversation are made to be loudspeaker arranged at one or a plurality of locations in the office etc., and the voice of the call on the line is simultaneously and automatically relayed. .

  That is, the present invention accommodates a plurality of extensions and one or more external lines (public communication lines), selects one of the external lines according to a connection request from one of the internal lines, and connects to the external line; A connection request (for example, 0) from one of the extension lines to an external line in a private branch exchange apparatus comprising means for making a call connection to a specific extension according to connection request information for an incoming call coming from one of the external lines Means for recognizing that a specific emergency number (for example, 119 or 110) preset in advance has been dialed, and after the call is terminated, from the outside line to the extension that generated the connection request Means for determining whether or not the call from the outside line is a call back from the emergency number, and when this means determines that the call is a call back And a means for setting and connecting the call path in response to the call back connection request and means for relaying and connecting the voice of the call path to a loudspeaker installed at a place other than the call back destination. .

  The loudspeaker may be a loudspeaker mounted on one or more telephones connected to the extension. The loudspeaker may be a loudspeaker installed for private broadcasting.

  When a specific number is dialed from one of the plurality of extensions while the voice of the communication path is relay-connected to the loudspeaker by the relay connection means, the call path of the extension on which the specific number is dialed is recalled. It can be configured to include means for interrupting connection to the communication path set and connected in response to the connection request. This specific number is a so-called password. This will be described in detail in the following [Third Example].

  The loudspeaker that relays and connects the voice of the communication path can be configured to be selectively set in advance in correspondence with the telephone number dialed with the specific emergency number. That is, the telephone set in the immediate vicinity of the telephone connected to the extension line dialed with the specific emergency number hardly needs to relay this voice and make it loud. For example, when a large number of extension telephones are used in one small room, it is meaningless to relay the above voices to the many extension telephones at the same time. There is almost no need to relay the information of injuries generated in the company to the extension telephone set up in the reception room for visitors.

  The emergency number can be set so as to be limited to a number (for example, 119) used for a fire fighting or emergency request. Relaying communications with the fire department to the company and sharing the information among many employees is meaningful in terms of safety management, but all the information that must be communicated to the police is not necessarily in the company. There is no need to share at the same time.

  Considering the case where it is not desirable to relay and connect all conversations with the police and fire department depending on the contents and circumstances, including a means for temporarily disabling means for relaying and connecting the voice on the communication path by operation can do.

  According to the present invention, the person who made the emergency contact concentrates on the necessary emergency measures such as fire extinguishing activities or transporting the injured person, and the extension telephone line is used even when the notification to the surroundings is delayed. Persons from other departments (or specific persons within them) communicate via telephone lines what emergency situations are occurring, what arrangements are being made, etc. Can be recognized accordingly. As a result, it is possible to appropriately determine that the emergency situation does not reach one's place and continue the work, or to take a self-rescue action or to take an evacuation preparation action. In addition, this allows the person in charge who has received the emergency call to concentrate on measures for the content of the emergency call by postponing reports and explanations to others.

(First Example)
The apparatus of the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining a state in which a call operation is performed from a telephone (A) connected to an extension of one company and “119” is dialed through an extension telephone exchange. A case where an injured person occurs in a company and an ambulance is requested will be described as an example. First, pick up the handset from the telephone, and press the “external line” button to instruct external line connection. Thus, when an outside line is captured, a dial tone from the outside line is heard. Subsequently, “119” is dialed as the telephone number. As a result, the line is connected to the emergency reception board of the Fire Department and the officer of the Fire Department responds. In this state, a conversation is exchanged between the emergency caller and the fire department reception desk, and when the officials of the fire department understand the details, the fire department officials follow the judgment of the ambulance. Make arrangements. The caller of the emergency call puts the handset and hangs up for the time being in response to the message “The ambulance will arrive at the scene after about minutes”.

  As a result, the connection line is temporarily abandoned as shown in FIG. 2. At this time, the emergency reception board of the Fire Department has information on the caller coming from the public communication network when the line connection is executed. The connection information is automatically left as record information. Next, as shown in FIG. 3, a call back connection is made from the emergency reception desk. As a result, the recorded information is referred to, the extension telephone line that first calls the fire department is selected according to the information, and a ringing tone (bell sound) is transmitted from the telephone (A) connected to the extension telephone line. Is done.

  At this time, as a feature of the private branch exchange according to the present invention, the telephone call (B) other than the telephone (A) that first made an emergency call is set so that the call contents of the call back can be intercepted through the speaker. . That is, as shown in FIG. 3, one or a plurality of telephones (B) connected to one or a plurality of extension telephone lines set in advance in the private branch exchange are selected and the telephone (B) is selected. It is set so that the call voice flows simultaneously through the installed speaker and one or a plurality of local speakers.

  Then, when the telephone (A) answers, the telephone (A) and the emergency reception board of the fire department can make a call. At this time, as a feature of the present invention, the two-way call voice of the telephone line used by the telephone (A) is relayed and amplified from the speaker installed in the extension telephone (B) and the local speaker. The telephone (A) is a telephone located near the site where an injured person has occurred. However, the telephone (B) is not necessarily installed at the site where the injured person occurred, but is a telephone installed in another department of the establishment, another room, another floor, another building, etc. is there. This telephone (B) can select and set a plurality of telephones as an intercept telephone (B) at the same time. For the time being, it is not possible to make a call from this telephone (B). If the handset of the telephone (B) is picked up, the transmitter will not be effective. This is in order not to disturb the emergency contact during a call. Note that the configuration in which a telephone call can be made from this telephone (B) or another telephone will be described in detail later in the third embodiment.

  This telephone (B) is a telephone installed in a department that is not directly related to the department in which the injured person has occurred. If this company is in a building, the telephone (A) where the injured person is located is on the second floor, for example, the telephone (B) may be a telephone on the third or fourth floor. Again, there may be a plurality of telephones (B). Three or ten is acceptable. In other words, it can be understood that an injured person appears to have requested an ambulance to be dispatched even at a place that is not directly related to the site where the injured person occurred. In this way, you can go for help or you can perform some kind of help.

  In the above example, we have explained that a person has been injured for the time being. However, if a fire has occurred, understand the situation in detail even if the situation is not directly related. Is effective in keeping the overall damage small. In other words, the person who is responding to the fire that occurred on the spot will not be able to contact other departments devoted to extinguishing the fire. Persons from other departments can properly understand the situation by intercepting communications with the Fire Department using the telephone line, so evacuation orders and other orders are issued. It is possible to make appropriate preparations in advance and prevent the damage from spreading.

(Second embodiment)
A more advanced connection utilization form using the present invention will be described as a second embodiment apparatus. FIG. 5 is a diagram for explaining the connection procedure of the second embodiment apparatus. This second embodiment is one application form of the present invention. The “sender” in the upper left of FIG. 5 is the Fire Department emergency reception desk, and the procedure for calling back the telephone subscriber who made the emergency call will be described with reference to FIG. After receiving the first emergency call, the Fire Department emergency reception desk once disconnected the telephone line and made the necessary arrangements, and then the telephone subscriber who issued an emergency call to obtain further necessary information Perform an operation to recall. This is equivalent to that described in the first embodiment. After this call back operation, multiple speakers are activated using the extension telephone line of the office that requested assistance, and the content of the call between the Fire Department and the person who made the first emergency call is relayed and amplified. is there.

  From the upper left of FIG. 5, the device installed in the fire department is obtained by the first 119 report, and the present invention is automatically transmitted via the public communication network according to the information of the report source that is automatically recorded. Connect to the implemented extension telephone switching network. When the extension telephone exchange network determines that the call is a call originated from the emergency number reception board, the extension telephone exchange network executes branch connection to the telephone set 1, the telephone set 2 and the private speaker. The telephone 1 is the telephone that first made an emergency call to the Fire Department, and the call back from the Fire Department is expected to be connected to the telephone 1. The telephone 2 is a telephone in another department of this company, which is not for requesting a telephone call to the telephone 2, but for the purpose of relaying the voice of the call to a loudspeaker provided in the telephone 2 It is. The in-house speaker is a speaker provided at one or a plurality of locations in the company. This speaker is also a component of this extension telephone exchange network. Although the telephone 1 is one telephone connected to one line, the telephone 2 is not necessarily one, and may be a plurality of telephones. When there are multiple telephones, the audio signals to the multiple telephones are connected in parallel.

  When the exchange connection of the extension telephone network is activated, a ringing tone is sent to the headphone of the fire department reception desk that is the caller. When the telephone 1 responds, the response signal is displayed on the fire department reception desk. As a result, a call can be made between the telephone of the fire department which is an emergency number sender and the extension telephone 1 of this company. The contents of the call are relayed to the company's telephone 2 (a plurality of telephones) and a local speaker so that a nearby person can intercept it.

  FIG. 6 is a diagram for explaining the connection procedure of the emergency response analysis in more detail. That is, when the telephone 1 responds as described above, it is determined by the transmitted identification code whether it is a call back from the emergency reception desk or a call other than that. When it is a call from the emergency reception desk, the call path control of the procedure prepared in advance is executed. That is, the telephone set 2 described in FIG. 5 (there may be a plurality of cases as described above) or the local speaker is set so that the contents of subsequent calls can be intercepted. Specifically, the speaker of the telephone 2 is activated and the telephone handset is controlled to be shut off. Then, the telephone 2 is turned on to indicate that the emergency number is being monitored. Even if the handset of the telephone 2 is picked up, the transmission of the handset is not effective. This is because the conversation voice with the emergency reception desk is intercepted and is not intended to interrupt the call with the emergency reception desk.

  In this way, conversations with the fire department or police can be intercepted at other parts of the corporate body, so even those who are not directly related to the emergency call understand the situation before giving detailed explanations. can do. This removes anxiety and, if deemed necessary, can initiate voluntary cooperation.

  Here, a loudspeaker capable of intercepting conversation contents should be set as small as possible in terms of facilities. Further, it is preferable that the line that can intercept the conversation content or the range of the speaker can be individually set depending on which telephone line is the telephone line that has made an emergency call first. .

(Third embodiment)
FIG. 7 is a diagram for explaining the connection procedure of the apparatus according to the third embodiment of the present invention. In the above description of the first embodiment device and the second embodiment device, in principle, the extension telephone that first issued the emergency call is called back in response to the call back from the emergency call destination (eg, the Fire Department emergency reception desk). It has been described that it is possible to answer, and only the conversation voice can be heard from the other extension telephones, and the voice cannot be answered from the other extension telephones. This was based on the idea that in a place not directly related to a fire or other emergency, it would be sufficient if the call could be intercepted and it was not necessary to interrupt the call. However, in this third embodiment device, it is convenient to be able to interrupt the call back from the emergency call destination even from a place not directly related to the emergency under specific conditions. It is based on the idea. This corresponds to the content described in claim 4 of the claims.

  With respect to FIG. 7, the telephone 1 responds to the call back connection from the reception desk of the fire department and starts the call, and the call contents are relayed to the telephone 2 and the local speaker in the first embodiment described above. The same as the apparatus and the second embodiment apparatus. In this third embodiment apparatus, when a specific number is transmitted from the telephone 3, the telephone 3 that has transmitted the specific number is connected to the telephone line connected to the fire department reception desk and the telephone 1 connected to the extension of this office. The feature is that it can be connected by interruption.

  When the interruption connection is executed, in this example, the fire department reception desk, the telephone 1 of the telephone line that first made an emergency call, and the telephone 3 that is interrupted and connected by a specific number are mutually connected in the form of a three-party call. Calls can be made. In principle, the telephone 3 for requesting the interrupt connection may be a telephone connected to any line of the extension telephone. Alternatively, the telephone 2 to which call voice is relay-connected may be used. Even a site where an emergency has occurred may be a telephone set installed at a location away from the site.

  The specific number is, for example, a personal identification number that only one person or a limited number of persons, such as a person in charge of management of the office where the private telephone exchange device is installed, knows and does not inform others. In this third example, it is necessary to respond to questions from the fire department or police when the person in charge of management is at a remote location in the company and cannot rush to the site where the emergency occurred. Assumes a situation such as This specific number does not necessarily have the same number of digits as the extension telephone number. Rather, it can be distinguished from a general extension telephone number by including a star (*) or pound (#) so that it can be distinguished from the extension telephone number. It can also be set as follows. When there are a plurality of managers or the like, the specific number is not limited to a single number, and a plurality of numbers can be set according to the number of managers or the like.

  With the configuration of the third embodiment, the present invention is not limited to the effect that the content of the emergency call back response can be intercepted, but the manager or the like directly responds to questions from the fire department or police. There are new effects that can be done.

  Although described as an extension telephone connected by a wired line, the present invention can be similarly applied to an extension telephone using a mobile phone or a PHS phone as its terminal phone.
