TECHNICAL FIELD OF THE INVENTION
The present invention relates to a monitoring system that performs automatic notification from a central processing unit based on an unsteady signal from a terminal device.
[0002]
[Prior art]
In recent years, the demand for surveillance systems in homes has increased with the increase in theft crimes. Conventionally, this type of monitoring system is composed of a combination of a sensor terminal for detecting an intruder and a central processing unit that issues an alarm. When the central processing unit receives an unsteady state such as occurrence of intrusion from each sensor terminal ( (For example, the user has contracted for a security service.) Automatically report to the outside line of the security company, voice communication with the central processing unit, or fax image of the camera connected to the central processing unit. There is a proposal that converts the data to a security company and transmits the converted data to a security company (for example, see Patent Document 1).
[0003]
Recently, an inexpensive surveillance system has been proposed in which the function of checking the image of the camera is eliminated and a simple telephone call function (home intercom function) is provided between each sensor terminal and the central processing unit. Hereinafter, the configuration will be described.
[0004]
FIG. 9 is a system block diagram of a conventional monitoring system of this type, wherein 1 is a central processing unit, and 2 to 4 are terminals. Communication between the central processing unit 1 and the terminals 2 to 4 is performed by wireless communication means described later.
[0005]
FIG. 10 is an internal block diagram of the central processing unit 1. 5 is a control means, 6 is a data communication means, 7 is a voice communication means for performing communication by modulating and demodulating voice, and 8 is an output from the data communication means 6 and is connected to an outside telephone to connect the voice communication means 7 to a public line. Public line connection means to connect to. Reference numeral 9 denotes an external line connection unit for connecting to a telephone line, reference numeral 10 denotes a display unit for displaying the overall state of the unit 1, and reference numeral 11 denotes a setting unit for setting the operation of the entire central processing unit 1. Reference numeral 12 denotes a voice output unit for amplifying the voice output from the voice communication unit 6, and reference numeral 13 denotes a voice input unit for transmitting voice from the central processing unit to the terminal.
[0006]
FIG. 11 is an internal block diagram of the terminals 2 to 4. Numeral 14 denotes an intrusion detecting means (not shown) which is a sensor for detecting a person, provided with an infrared light receiving / emitting unit, and responding to a change in the infrared output emitted from 1 to 3 m around the terminals 2 to 4. In the case of a sensor that detects the open / closed state of the window, the unsteady state is detected in response to a change in the proximity of the magnet by opening / closing the window.
[0007]
That is, by installing this terminal near a window in the house or in the living room, it is possible to detect intrusion into the house from outside.
[0008]
Reference numeral 15 denotes a terminal control unit which wirelessly transmits an unsteady signal from the intrusion detecting means 14, that is, information that an intrusion has occurred, to the central processing unit 1 together with its own terminal code using the data communication means 16. Is what you do. Reference numeral 17 denotes an audio communication unit which communicates an audio signal with the central processing unit 1. Reference numeral 18 denotes an audio output unit for increasing the volume of the audio signal received and demodulated by the audio communication unit 17. Reference numeral 19 denotes a voice input unit, by which voice around the terminal 2 is collected, modulated by the voice communication unit 17, and transmitted to the central processing unit 1. Reference numeral 20 denotes a buzzer which sounds an alarm sound by the terminals 2 to 4 themselves.
[0009]
The operation will be described based on the above configuration. When the user goes out, the control unit 5 outputs a signal to the data communication unit 6 to switch the terminals 2 to 4 to the alert mode by setting the alert mode by the setting unit 11 of the central processing unit 1. Then, the terminal control unit 15 switches from the non-alert mode to the alert mode via the data communication unit 16 of the terminals 2 to 4 and simultaneously enters a state in which a signal from the intrusion detection unit 14 can be accepted. I do.
[0010]
During a vigilance operation, when there is an intrusion into the house from the outside near the window or in the living room where the terminals 2 to 4 are installed, the intrusion detecting means 14 operates, and the data communication means 16 in the terminals 2 to 4 As a result, an unsteady state occurrence signal is output. Upon receiving this signal, the data communication means 16 transmits a signal to the data communication means 6 of the central processing unit 1. This signal first transmits an address code of its own terminal and a status code indicating that an intrusion has occurred. In the central processing unit 1, the data communication means 6 of the central processing unit 1 receives this transmission signal, determines which terminal the signal is from, and further receives a signal indicating that intrusion has occurred. On the basis of this signal, the central processing unit 1 outputs to the terminal which has output the signal of occurrence of the unsteady state so as to sound an alarm sound through the data communication means 6, and outputs the signal of occurrence of the unsteady state. When the data communication means 16 receives this, the terminal control section 15 operates the buzzer means 20 and emits an alarm sound.
[0011]
On the other hand, the central processing unit 1 operates the public line connection means 8 to establish a communication configuration with the telephone outside the home corresponding to the telephone number registered in advance from the external line connection unit 9. As a result, the voice around the terminal can be monitored by the telephone outside the home through the voice input means 19, and the surrounding situation can be intercepted. If necessary, the intruder is threatened by the voice of the user from the voice output means 18 through the telephone.
[0012]
The problem here is when the user (housekeeper) returns home to which the terminals 2 to 4 are installed. In other words, before the family member switches from the alert mode to the non-alert mode on the setting unit 11 of the central processing unit 1 in the house when returning to the house, the user (the suspicious individual) enters the guarded terminals 2 to 4 installed in the house. Intrusion into the house).
[0013]
A new proposal has been made for this problem, which will be described with reference to a flowchart shown in FIG.
[0014]
When the alerting operation is started, the central processing unit 1 waits for the intrusion detecting means 14 of the terminals 2 to 4 to detect the unsteady state. However, here (for easy explanation, the central processing unit 1 is uniformly attached to the entrance door). An example will be given in which the intrusion detection means 14 of the terminal device 2 detects an unsteady state. As shown in the flowchart of FIG. 12, when the intrusion detecting means 14 of the terminal 2 detects an unsteady state in S1, a short alarm sound (about one second) is generated by the buzzer 20 of the terminal 2 in S2 to S4. , A one-minute stop period is provided in S5, and the user switches the alert mode to the non-alert mode in the setting unit 11 of the central processing unit 1 during the stop period of S5 in S6 (that is, If the operation of warning release is performed), the warning operation is terminated. If the operation of warning release is not performed, the buzzer means 20 of the terminal 2 is operated again in S7 to generate a full-scale warning sound. Sound. (Simultaneously call outside and report). In this way, when the terminal detects the intrusion of a suspicious person from the outside, the terminal sounds a short alarm and threatens (in addition to the entrance where the terminal 2 is installed) to deter intrusion into the house, and thereafter It sounds an alarm and drives out the suspicious person. On the other hand, in the case of a family member, the threat by the short alarm sound is well known, so that the alarm is not surprised by operating the central processing unit 1 in the house during the suspension period (one minute in this example). is there.
[0015]

[0016]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, the central processing unit 1 attaches the terminal that emits the short alarm sound so that only the terminal that detects the unsteady state emits a short alarm sound when the unsteady state is detected. There is a problem that the intruder cannot easily give a full-scale alarm by destroying the terminal during the suspension period (one minute in the above example) during the suspension period (one minute in the above example). Was.
[0017]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. When an unsteady state is detected during an alert, a monitor capable of sounding an alarm buzzer effectively without specifying a mounting position of each terminal at that time. The purpose is to provide a system.
[0018]
[Means for Solving the Problems]
In order to solve the conventional problem, a monitoring system according to the present invention includes a plurality of terminals and a single central processing unit that monitor a steady or unsteady state, and a communication between the terminal and the central processing unit. Data communication means for transmitting and receiving data on the steady state or unsteady state, and a buzzer means to sound an alarm sound in the terminal device, the central processing unit is monitoring the steady or unsteady state In the case where a signal that is in an unsteady state is received from the terminal, the buzzer means of the terminal that transmitted the unsteady state and the buzzer of the terminal that does not transmit the unsteady state are stopped after operating for a predetermined time. Then, the buzzer means of the terminal device which has transmitted the unsteady state is operated. Thus, when the central processing unit detects an unsteady state (intrusion from outside) in each terminal while monitoring the steady or unsteady state, not only the terminal that has detected the unsteady state but also other terminals The alarm sounds for a short period of time simultaneously using the buzzer means, so that multiple alarm sounds resonate in the house, making it difficult to identify the mounting position of each terminal, and at the same time it is effective against intruders entering the house This makes it possible to perform a full-scale alarm by a terminal that has detected an unsteady state after a period of suspension after a threat.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the first aspect of the present invention, the steady state or the unsteady state is provided between a plurality of terminals and one central processing unit that monitor a steady or unsteady state, and the terminal unit and the central processing unit. Data communication means for transmitting and receiving data relating to the terminal device, and a buzzer means for sounding an alarm sound in the terminal device, the central processing unit, during monitoring of a steady or unsteady state, from the terminal device unsteady When a signal that is in a state is received, the terminal that transmitted the unsteady state and the buzzer unit of the terminal that does not transmit the unsteady state are stopped after operating for a predetermined time, and then the unsteady state is changed. The buzzer means of the transmitting terminal is operated so that the central processing unit monitors the terminal in an unsteady state (from outside) while monitoring the steady or unsteady state. (Intrusion) is detected, the buzzer means of other terminals as well as the terminal that detected the unsteady state is used to simultaneously generate short-time alarm sounds. The threat can be effectively threatened without specifying the mounting position of the terminal device, and a full-scale alarm can be provided by the terminal device that has detected an unsteady state after the suspension period.
[0020]
According to a second aspect of the present invention, in the monitoring system according to the first aspect, the central processing unit includes a first operation input unit for setting a time for operating the buzzer unit by an operation of a user. Or, during the monitoring of the unsteady state, if a signal that is in the unsteady state is received from the terminal, the buzzer means of the terminal that transmitted the unsteady state and the terminal that does not transmit the unsteady state, The terminal is operated for a time set by the first operation input means, whereby an unsteady state (intrusion from outside) is detected in each terminal while the central processing unit monitors the steady or unsteady state. If it is detected, in addition to the terminal that has detected the unsteady state, the buzzer sound time of the buzzer by the buzzer means of another terminal is set according to the environment in which each terminal is installed (by the operation setting means of the central processing unit). freedom Setup is possible. In other words, a short buzzer sounding time can be set in a quiet residential area, while a longer buzzer sounding time can be set in a red light district where the surrounding sounds are noisy. .
[0021]
According to a third aspect of the present invention, in the monitoring system according to the first or second aspect, the central processing unit is configured to perform a second operation input for setting a specific terminal among the terminals by a user operation. Means, when monitoring a steady or unsteady state, when receiving a signal that is in an unsteady state from the terminal, the terminal that transmitted the unsteady state and the terminal that does not transmit the unsteady state. The buzzer means of the specific terminal set by the second operation input means is operated for a predetermined time, whereby the central processing unit monitors each terminal while monitoring the steady or unsteady state. When an unsteady state (intrusion from outside) is detected by the device, the terminal that sounds a short-time alarm buzzer in addition to the terminal that detected the unsteady state can be freely set (by the operation setting means of the central processing unit). Can be set to That. In other words, if a terminal installed in a specific room that dislikes noise due to circumstances such as a baby sleeping, do not sound a short-time alarm buzzer when other terminals detect an unsteady state. For example, the weight of the alarm buzzer can be set for each terminal device.
[0022]
According to a fourth aspect of the present invention, there is provided a program for causing a computer to execute at least one unit of the monitoring system according to any one of the first to third aspects. According to this configuration, the monitoring system detects the unsteady state when the central processing unit detects the unsteady state in each terminal during the monitoring of the steady or unsteady state during the monitoring of the steady or unsteady state. In addition to the detected terminal, the buzzer of another terminal sounds in a short time, so multiple alarm sounds resonate in the house and enable effective threatening without specifying the mounting position of each terminal Things. Further, since the program is a program, a part or all of the monitoring system of the present invention can be easily realized using a microcomputer or the like. Further, the program can be easily distributed by recording it on a recording medium or distributing the program using a communication line.

【Example】
Hereinafter, embodiments of the present invention will be described with reference to FIGS. Components having the same configuration as the above-mentioned conventional example are denoted by the same reference numerals, and description thereof will be omitted.
[0024]
(Example 1)
FIG. 1 is a system block diagram of a monitoring system according to the first embodiment, FIG. 2 is an internal block diagram of a central processing unit according to the first embodiment of the present invention, and FIG. 4 is a flowchart showing the operation of the main part of the central processing unit 21. As shown in FIGS. 1 to 3, the configuration is the same as that of the conventional example except for the central processing unit 21.
[0025]
The operation and operation of the monitoring system configured as described above will be described below.
[0026]
When the alerting operation is started, the central processing unit 1 waits for the intrusion detecting means 14 of the terminals 2 to 4 to detect the unsteady state. An example will be described in which the intrusion detection means 14 of the terminal device 2 attached to the door detects an unsteady state.
[0027]
In addition, the intrusion detecting means 14 includes a human sensor for detecting a human body. In this case, an infrared receiving / emitting unit is provided to detect an unsteady state according to a change in an infrared output emitted from 1 to 3 m around the sensor. That's why.
[0028]
As shown in the flowchart of FIG. 4, when the intrusion detecting means 14 of the terminal 2 detects an unsteady state in S1, the buzzer sounds the buzzer 20 of the terminal 2 in S2, and the terminal in S8. 3 starts the buzzer sound of the buzzer means 20, starts the buzzer sound of the buzzer means 20 of the terminal device 4 in S9, and calls a pre-warning in S3 (from the meaning of a pre-warning before a full-scale warning). A short alarm sound is sounded for two seconds, the buzzer being sounded is stopped in S4 and S10, and a one-minute stop period is provided in S5.
[0029]
Here, in S6, when the user (housekeeper) switches the alert mode to the non-alert mode in the setting unit 11 of the central processing unit 1 in the house during the suspension period of S5 (that is, when the alert release operation is performed) ), The warning operation is terminated. However, if the warning release operation is not performed, the buzzer means 20 of the terminal device 2 is operated again in S7 to generate a full-scale alarm sound. Thus, when the central processing unit detects an unsteady state (intrusion from outside) in each terminal while monitoring the steady or unsteady state, not only the terminal that has detected the unsteady state but also other terminals The alarm sounds for a short time all at once using the buzzer means, and multiple alarm sounds resonate in the house, making it difficult to identify the mounting position of each terminal. A terminal that not only reduces the risk of being destroyed by intruders, but also effectively intimidates the intruder by the intimidating sounds from all terminals installed in the house, and detects an unsteady state after a period of suspension after that A full-scale alarm can be made with a container.
[0030]
In addition, considering recent criminal circumstances, suspicious persons from the outside often enter the living room at the back of the house in a short period of time, and how the surveillance system intrudes suspicious persons from outside into the house. (For example, how to deter entry into the living room even if you enter the entrance) is also an important factor. A large effect can be expected if the alarm buzzer sounds for a short time at the time of detection. On the other hand, continuous buzzing of the full-scale alarm buzzer only with the terminal that has detected the unsteady state after the suspension period mentioned in the above example has a great significance in repelling the intruder who has entered, Around the terminal that detected the condition (for example, the entrance door or veranda) is often destroyed (neighboring residents, etc.). An important role to convey is that when one of the terminals detects an unsteady state, the alarm buzzer sounds for a short time at the same time (eventually a full-scale alarm buzzer sounds). A great effect can be expected in making it difficult to find a terminal device that has detected an event.
[0031]
In the present embodiment, the time during which the terminals simultaneously sound the alarm buzzer for a short time and the stop time are specifically shown. However, these times are not particularly limited and may be set according to the purpose of the monitoring system. You can set it freely.
[0032]
In this embodiment, the number of terminals is specifically shown. However, the number is not particularly limited, and as long as the address code and the status code of the terminal can be specified, the number of terminals is any number. But it doesn't matter.
[0033]
(Example 2)
FIG. 5 is an internal block diagram of the central processing unit according to the second embodiment of the present invention, and FIG. 6 is a flowchart showing the operation of the main part of the central processing unit 21. As shown in FIG. 5, the first operation input means 25 is for setting a time for sounding an alarm buzzer for operating the buzzer means 20 of the terminals 2 to 4 by a user's operation. Other than that, the configuration is the same as that of the first embodiment except for the control unit 24.
[0034]
The operation and operation of the monitoring system configured as described above will be described below.
[0035]
As shown in the flowchart of FIG. 6, the processing added to the first embodiment is S11 and S12.
[0036]
When the alerting operation is started and the intrusion detecting means 14 of the terminal 2 detects an unsteady state in S1, the buzzer sounds of the buzzer 20 of the terminals 2 to 4 are started in S2, S8 and S9, and S11 is performed. The user calls the preset time t at which the user sounds the buzzer means 20 with the first operation input means 25, and the alarm sound is short (only one second in this embodiment) by the time t called at S12. Is sounded, and the buzzer sounding in S4 and S10 is stopped. With this, when the central processing unit detects an unsteady state (intrusion from outside) in each terminal while monitoring the steady or unsteady state, other terminals are added to the terminal that has detected the unsteady state. The sounding time of the alarm buzzer by the buzzer means can be freely set (by the operation setting means of the central processing unit) according to the environment in which each terminal is installed. In other words, a short buzzer sounding time can be set in a quiet residential area, while a long buzzer sounding time can be set in an entertainment district where the surrounding sounds are noisy.
[0037]
In the present embodiment, the time during which the terminals simultaneously sound the short-time alarm buzzer is set to the time common to the terminals 2 to 4, but may be set for each terminal.
[0038]
(Example 3)
FIG. 7 is an internal block diagram of the central processing unit of the third embodiment, and FIG. 8 is a flowchart showing the operation of the main part of the central processing unit 21. As shown in FIG. 7, the second operation input means 27 is for setting a specific terminal among the terminals by a user's operation. Specifically, the other terminals are in an unsteady state. For each terminal, it is set whether or not to sound a short-time alarm buzzer in conjunction with the detection of the alarm. (The information set for each terminal device is retained and can be called by the control means 26). Otherwise, the configuration is the same as that of the second embodiment except for the control unit 26.
[0039]
The operation and operation of the monitoring system configured as described above will be described below.
[0040]
As shown in the flowchart of FIG. 8, the processes added to the second embodiment are S13 to S15.
[0041]
When the alerting operation is started and the intrusion detection means 14 of the terminal 2 detects an unsteady state in S1, the buzzer sounds the buzzer 20 of the terminal 2 in S2, and the user starts the buzzer in S13. The information on whether or not to sound a short-time alarm buzzer for each terminal device set in advance by the second operation input means 27 is collectively called, and the setting contents of the second operation input means 27 are set in S14 and S15. Accordingly, the short-time alarm buzzers of the terminals 3 and 4 are sounded. In this way, if the central processing unit detects an unsteady state (intrusion from outside) at each terminal while monitoring the steady or unsteady state, a short-time alarm is added to the terminal that detected the unsteady state. The terminal that sounds the buzzer can be set freely (by the operation setting means of the central processing unit). In other words, if a terminal installed in a specific room that dislikes noise due to circumstances such as a baby sleeping, do not sound a short-time alarm buzzer when other terminals detect an unsteady state. You can set a short time alarm buzzer on / off for each terminal.
[0042]
In the above embodiment, the first operation input unit 25 and the second operation input unit 27 may be provided as one. The operation input means may also be used to input an operation time (1 minute of S5 in FIG. 4) from the operation of the first buzzer to the operation of the second buzzer.
