BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency call system suitable for home security systems.

[0002]

2. Description of the Related Art Various home security systems have been developed in order to promptly deal with abnormalities and emergency situations that have occurred inside a house. One of the particularly important requirements for this system is the emergency call function, and it is desirable that a quick and reliable contact system can be established in response to an emergency. As a conventional emergency call system, pressing an emergency push button located in various places inside the house will send a call to a predetermined place through a telephone line, or wirelessly in the house to improve portability. Some have installed a master unit and a slave unit capable of communication (Japanese Patent Laid-Open No. 64-62799). In the latter case, when an emergency signal is wirelessly transmitted from the child device having an emergency button to the parent device, the parent device receives the emergency signal and reports it to a predetermined place via a telephone line. At this time, it is possible to make an automatic call between the master unit and the slave unit, and the user can communicate with the outside through a route of slave unit → master unit → telephone line. In this case, the contact information is generally limited to a security company that has made a contract beforehand in order to avoid false alarms.

[0003]

By the way, in the above-mentioned conventional emergency call system, the contact is made to the security company in order to avoid a mistake in the call, but when the contract fee with the security company cannot be neglected. There was a problem that this system could not be used. The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide an emergency call system capable of setting a contact point in an emergency at an arbitrary place without causing a report error.

[0004]

In order to solve the above-mentioned problems, in the invention of claim 1, a contact storage means for storing the telephone number of the contact and a voice message corresponding to the contact are stored. Message storage means, an operation section that is operated in an emergency, and when the operation section is operated, the telephone number in the contact storage means is read to make a call, and
And a control means for reading the corresponding voice message from the message storage means and transmitting it to the contact. Further, in the invention according to claim 2, it has a master unit connected to a telephone line, and a slave unit that wirelessly exchanges signals with the master unit, and the operation unit is a slave unit. The contact storage unit, the message storage unit, and the control unit are provided in the master unit. In the invention according to claim 3, instead of the operating means,
It is characterized in that voice recognition means for outputting a detection signal when a predetermined message with a voice registered in advance is issued is provided, and the control means starts operation when the detection signal is output. Further, in the invention according to claim 4, the contact storage means stores the telephone numbers of a plurality of contacts, the message storage means stores a plurality of messages corresponding to the contacts, and the control is performed. The method calls the next contact based on a predetermined priority when unable to reach the contact who made the call, and gives the highest priority when the contact with the lowest priority cannot be reached. It is characterized by making a call again from a contact with a high ranking.

[0005]

Function: The voice message corresponding to the contact information is transferred to the other party by the control means. That is, the predetermined message is transferred prior to the call, thereby avoiding missed calls.

The logic circuit 27b decodes and outputs a plurality of recognition signals supplied from the voice recognition LSI 27a.

Next, the structure of the slave unit 3 will be described with reference to FIG. The slave 3 has many configurations in common with the master 2, and includes the CPU 30, push buttons 31A, 31B, and 3
1C, the detection unit 32, the wireless unit 34, the voice circuit 35, and the voice recognition circuit 37 have the same functions as the corresponding units of the parent device. In particular, the push buttons 31A, 31B, 31C and the push buttons 21A, 21B, 21C are set to select the same group. Voice circuit 35 of handset 3
A speaker 40 and a microphone 41 are connected to the wireless unit 3
The signal supplied from the speaker 4 is generated from the speaker 40, and the voice of the user 6 is collected by the microphone 41 and supplied to the wireless unit 34 and the voice recognition circuit 37.

B: Operation of Embodiment Next, the operation of this embodiment having the above configuration will be described. First, as an initial registration process, the push button 31A,
With respect to 31B, 31C and push buttons 21A, 21B, 21C, telephone numbers of contacts are registered and desired messages are recorded. The recording of the message is performed by the user 6 blowing a message from the microphone 41 connected to the child device 3. That is, the blown-in voice signal is supplied to the voice synthesis LSI 26 via the radio units 34 and 24 and the voice circuit 25 and recorded. Here, the push buttons 31A, 31B, 31C and the push buttons 21A, 2
The priority order of contacts for 1B and 21C is, for example,
It is set in the order of registration or by operating an operation button (not shown) for instructing the priority. Correspondence between the contact information and the message is performed in the same manner. In addition, the voice recognition circuits 27 and 37 of the parent device 2 and the child device 3
The message is recorded in the same manner as in the voice synthesis LSI 26.

Next, the call operation in an emergency will be described with reference to the flow charts shown in FIGS. (A) When the push button is pressed When an emergency occurs and the push button 21A of the master device 2 or the push button 31A of the slave device 3 is pressed, the CPU of the master device 2
20 detects this, and the processing shown in FIGS. 6 to 8 is started. In this case, when the push button 21A of the base unit 2 is pressed, this switch signal is directly supplied to the CPU 20,
It is recognized that the button has been pressed. On the other hand, handset 3
When the push button 31A of is pressed, this switch signal is detected by the CPU 30 and transmitted to the wireless unit 24 of the parent device 2 via the wireless unit 34. And the CPU 20
Recognizes that the push button 31A has been pressed based on the signal supplied from the wireless unit 24.

When the button is pressed, the process proceeds from step SP1 shown in FIG. 6 to step SP2 to call the registration destination registered corresponding to the push button. This call is made by the control unit 23. next,
"YES" (during a call) is determined whether the call destination is busy
If so, it is determined whether or not the registration destination is registered (steps SP3 and SP4). If this determination is "NO", the process returns to step SP2 to call the registration destination again. On the other hand, if there is registration at the registration destination, the contact is called and it is determined whether or not it is busy (steps SP5 and SP6). If the registration destination is busy, the process proceeds to step SP7 shown in FIG. 7 and it is determined whether or not the registration destination is registered. If this determination is “NO”, the process returns to step SP2 shown in FIG. 6 to call the registration destination again, and if “YES”, the registration destination is called. Then, it is determined whether or not the registration destination is busy. If busy, the process proceeds to step SP2 to call the registration destination again. In this way, if the registration destination that made the call is busy, the next registration destination is automatically called, and the registration destination → registration destination → registration destination → registration destination is repeated in this order. ..

If the registration destination is not busy, the process proceeds to step SP10 shown in FIG. 6 and the call count is set to zero. The call count is a number indicating how many times the ringing tone is sounded, and is counted by using a predetermined register in the CPU 20, for example. Next, it is determined whether the call count is 20 or more, and this determination is “NO”.
If so, it is judged whether or not the line is connected, and "N
If "O", the call count is incremented by 1 and the process returns to step SP11 (steps SP11, 12,
13). After that, step SP11 to step SP13
Cycle, and before the call count reaches 20,
When the line with the partner is connected, the CPU 20 transfers the message corresponding to the registration destination from the voice synthesis LSI to the read control unit 23. Then, the control unit 23 transmits the message to the destination twice via the telephone line 4 (steps SP14 and SP15). As a result, a message corresponding to the contact information in case of emergency is automatically transmitted. After transmitting the message, the process proceeds to step SP16 shown in FIG. 8 to establish a two-way call state, enabling a call between the user 6 and the contact person. Next, in step SP20, it is determined whether or not the callee's telephone has been disconnected. This judgment is "YE
It continues until it becomes "S". Then, when the callee's telephone is cut off, the caller's telephone is cut off and the processing is terminated (steps SP21 and SP22).

On the other hand, when the call count reaches 20 while the line with the other party is not connected, the determination in step SP12 becomes "YES", and the processing in steps SP4 to 6 is performed. That is, if there is registration at the registration destination, a call can be made here (step SP5). Then, if the registration destination is not busy, the processing of steps SP30 to SP33 is performed. These processes are performed by the above-mentioned step S
This is a process corresponding to the process of P10 to step SP13. Then, if the line is connected before the call count reaches 20, the message corresponding to the registration destination is transmitted twice (steps SP34 and 35 in FIG. 8), and thereafter, the processing of step SP16 to step SP22 is performed as described above. ..

When the call count reaches 20 without the other party's line being the registration destination being connected, the same processing as above is performed for the registration destination. Step SP shown in FIG.
40 to step SP45 are processes corresponding to step SP10 to step SP15. As can be seen from the above description, when the other party cannot answer the call due to the absence of the other party, the processing automatically shifts to the next party when the call count reaches 20. .. The above-mentioned operation is performed by the other push buttons 21B, 21C, 31B,
When 31C is pressed, the same operation is performed. Also, if the push button is pressed incorrectly, pressing the same button again cancels the notification process and ends the operation.

(B) When voice recognition is performed When the user 6 does not press the push button and screams "Takesuke" or the like, this voice is input through the microphone 41 of the handset 3 and the voice recognition circuit. 37. If the voices and words in this case match those recorded in advance, then FIG.
A signal is supplied from the speech recognition LSI 27a shown in to the logic circuit 27b, and the decoded signal is output from the logic circuit 27b. This signal corresponds to push buttons 21A-21C and 31A-31C,
The information is transmitted to the parent device 2 via the CPU 30 and the wireless unit 34. As a result, the CPU 20 of the parent device 2 performs exactly the same processing as when the push button is pressed. For example, the signal output from the logic circuit 27b is the push buttons 21A, 3
If it corresponds to 1A, step SP50 of FIG.
Through step SP2. When the user 6 screams while holding the handset 5 of the base unit, the voice recognition circuit 27 in the base unit 2 performs the same voice recognition as above.

When the notification process is activated by voice recognition, the physical action of pushing the push button can be omitted, and it is suitable for persons with physical injuries. It is also effective in preventing mischiefs caused by children's mischief and carelessness.

(C) When the detection units 22 and 32 detect an abnormality. When the temperature sensors provided in the detection units 22 and 32 detect the room temperature of 100 ° C or more, the intruder detector detects an intruder, and the pulse detector detects an abnormality, the fire department respectively. , Report to police station and hospital. The telephone number of each institution is registered in advance, and the message is also registered in advance as in the case described above. Also,
At the time of reporting, an alarm is generated from the speaker 40 of the child device 3. Further, similar to the case of the push button, some contacts are registered, and if any one is absent, the contacts are sequentially transferred to the next contact as in the case described above.

C: Modified Example Here, an example of the appearance of the parent device 2 is shown in FIG. In the figure,
Buttons 0 to 9 are used when making a normal call. The outer shape of the parent device 2 is not limited to this, and can be any design. In addition, handset 3
Can also be shaped so that it can be attached to the body.
