Further, the home security device according to the present invention has a function setting switch for setting to one of a toilet / bus call and a crime prevention depending on the configuration of the sensor.

[0013]

[Function] The sensor input circuit of the home security device is
If the type of connected sensor is ON type, ON type / O
It is set to ON type by the FF type setting switch, and is set to OFF type in case of OFF type sensor. When set to the ON type, the signal detection circuit detects a make operation of the sensor and outputs an abnormal signal to the control device. When the OFF type is set, the OFF type bias circuit applies a bias to the OFF type signal detection circuit, and the OFF type signal detection circuit detects a break operation of the sensor, and outputs an abnormal signal to the control device.

The input circuit is set to a holding type or a non-holding type by a holding / non-holding type setting switch. When the holding type is set, the holding circuit holds the output of the abnormal signal to the control device together with the signal detection circuit. Therefore, once the sensor operates, the abnormal signal is continuously output to the control device until a cancel operation is performed. When the non-holding type is set, the holding circuit does not operate, and outputs an abnormal signal to the control device only while the sensor is operating.

The function setting switch has a sensor input circuit for a toilet / bath call sensor according to the configuration of the sensor.
It is set for any of the security sensors, and this setting can be changed even after the home security device is installed.

Further, the apparatus has a speaker 3 for outputting an alarm sound through an alarm sound generation circuit 1 and an alarm sound amplification circuit 2 in response to an alarm signal output from a CPU 10, a fire display, a security alarm display, and a toilet / bath call display. An alarm display device 7 for displaying an alarm is provided as an output system. The device further comprises a toilet / bath call sensor 170
When the sensor S connected to the sensor input circuit IP1 is the security sensor 160, the sensor S connected to the sensor input circuit IP2 is connected to the toilet / bath when the sensor S connected to the sensor input circuit IP1 is the security sensor 160. Function setting switches SW4-1 and SW4-2 to be set for toilet / bath call in case of call sensor 170
(However, only SW4 and one are shown in the figure.) A security state indicator 8 for indicating that the connected security sensor 160 is in a security state, and power is supplied to the home security device from AC 100 volts. The power supply circuit 120 is provided. The operation switch SW3 is connected to the input port PI2 of the CPU 10, and the function setting switch SW4 is
, And are grounded when both switches are closed. Although not shown in FIG. 2, when two sensor input circuits IP are connected as described above, two function setting switches SW4 are also required. The switch SW4-1 is connected, and the function setting switch SW4-2 is connected to the input port PI3-2.

In this home security device, various types of sensors S such as a security sensor 160 and a toilet / bath call sensor 170 can be used. FIG. 3 shows a sensor S that can be connected. here,
Terminals M and C are connection terminals to the sensor input circuit IP. Figure 3 for normal toilet / bus call sensor
The type of (a), (b) or (c) is used. FIG. 3A shows a non-lock type switch sensor,
Further, it can be used as a holding sensor or a non-holding sensor depending on whether or not the input circuit has an operation holding function. FIG. 3B shows a lock type switch sensor, and FIG. 3C shows a self-holding type sensor. The non-lock type switch referred to here is a switch that is in an operating state only when the button is pressed because the button is not mechanically locked, and the operating state is not maintained. On the other hand, the lock-type switch is a type in which when the button is pressed once, the button is mechanically locked and the operation state is maintained, and the lock is released by pressing the button again. In addition, the self-holding type sensor is one in which a circuit of the sensor itself has a holding function so that an operation state is continued when a button is pressed once. In the operation state, the operation confirmation LED is turned on, and when the holding operation is released, the power of the input circuit is turned off by the recovery switch.

For a security sensor, a normal ON type sensor (FIG. 3)
(D)) or an OFF-type sensor (FIG. 3E) is used. An ON-type sensor is a type in which a plurality of contacts are connected in parallel, all the contacts are open when the sensor is not operating, and the sensor operates when one of the contacts closes (turns on). is there. On the other hand, an OFF-type sensor is a type in which a plurality of contacts are connected in series, all the contacts are closed when the sensor is not operating, and the sensor operates by opening (turning off) any of the contacts. is there.
Normally, the security sensor employs a non-locking type switch for both the ON type and the OFF type, and the operating state of the input circuit is held by the holding function of the input circuit.

In spite of the fact that various types of sensors S can be connected as described above, the home security device according to the present invention has a function capable of coping with various sensors in the sensor input circuit IP. it can. FIG. 1 shows a circuit configuration of the sensor input circuit IP. The sensor input circuit IP is configured such that the sensor input circuit IP is turned on or off according to the configuration of the terminals M and C connected to the sensor S and the configuration of the sensor connected via the terminals M and C.
A lock-type ON / OFF setting switch SW1 that is set to one of the FF type, and a lock-type holding type that sets the sensor input circuit IP to either the holding type or the non-holding type according to the configuration of the sensor. And a non-holding setting switch SW2. The sensor input circuit IP includes a power-on circuit C1 (including transistors Q6 and Q9) for turning on the power under the control of the control device at the time of monitoring the toilet / bath call by the sensor and a time of monitoring the crime prevention, and a power-on circuit C1. And a signal detection circuit C2 (including a transistor Q7) interposed between the sensors to detect a make / break operation of the sensor and output it to the CPU 10 as an abnormal signal, and a holding / non-holding type setting switch for setting the holding type. At the time, the holding circuit C3 (including the transistor Q8) for holding the output of the abnormal signal to the CPU 10 together with the signal detection circuit C2, and the ON type / OFF type setting switch SW1 interposed between the power supply circuit and the sensor are set to the OFF type. OFF type that detects the break operation of the OFF type sensor and operates the signal detection circuit C2 Signal detection circuit C4 (including the transistor Q2) and an OFF-type bias circuit C5 (including the transistors Q1 and Q3) for applying a bias to the OFF-type signal detection circuit C4 when set to the OFF type by the ON / OFF type setting switch SW1. ) And ON type / OF
ON type current limiting circuit C6 for limiting the current from terminal M when set to ON type by F type setting switch SW1
(Including the transistors Q4 and Q5).

This sensor input circuit IP is a power-on circuit C
1 transistor Q9 is connected to the circuit CPU1 via the resistor R22.
0, and the transistor Q7 of the signal detection circuit C2 is connected to the input port PI1 of the CPU 10 via the resistor R14. FIG. 1 shows one sensor input circuit IP connected to the CPU 10, but it is also possible to connect the sensor input circuit IP1 and the sensor input circuit IP2 having the same configuration as shown in FIG. it can. Similarly, in this case, the sensor input circuit IP1 is connected to the transistor Q9 of the power-on circuit C1 through the resistor R22.
Connected to the output port PO1-1 of the PU10, and the transistor Q7 of the signal detection circuit C2 is connected to the CPU 10 via the resistor R14.
To the input port PI1-1. In the sensor input circuit IP2, the transistor Q9 of the power-on circuit C1 is connected to the resistor R
22 to the output port PO1-2 of the CPU 10 via
The transistor Q7 of the signal detection circuit C2 is connected to the input port PI1-2 of the CPU 10 via the resistor R14.

The ON / OFF setting switch SW1 sets the sensor input circuit IP to the ON type or the OFF type according to the sensor S connected to the sensor input circuit IP. , The ON-type current limiting circuit C6 operates, and when it is off, the OFF-type sensor is supported, and the OFF-type signal detection circuit C4 and the OFF-type bias circuit C5 operate. The holding / non-holding type setting switch SW2 sets the sensor input circuit IP to which the sensor is connected to either the holding type or the non-holding type. When the switch is on, the holding circuit C3 does not operate and the sensor input circuit I
P does not have a holding function, but when turned off, the holding circuit C3
Operates and has a holding function. Both switches are lock type switches.

The operation switch SW3 is a switch operated by the user and is a non-lock type switch, which can restore the toilet / bath call sensor and set / cancel the security sensor. The function setting switch SW4 is a lock type switch, and is set when the sensor S is connected. That is, when the sensor connected to the sensor input circuit IP is the security sensor 160, the function setting switch SW4 is turned on,
As a result, the sensor input circuit IP functions as an input circuit for the security sensor 160. When the sensor connected to the sensor input circuit IP is the toilet / bath call sensor 170, the function setting switch SW4 is turned off,
Thus, the sensor input circuit IP functions as an input circuit for the toilet / bath call sensor 170. When security is set by the operation switch SW3, the security status indicator 8 is turned on.

Although not shown in FIG. 2, when two sensor input circuits IP are connected, there are two function setting switches SW4 corresponding to the sensor input circuits IP. is necessary. When the two sensor input circuits IP are connected to the crime prevention state indicator 8, even if the corresponding side is turned on,
The two sensor input circuits IP may be turned on collectively.

Next, the operation of the sensor input circuit IP when each of the sensors S shown in FIG. 3 is connected will be specifically described with reference to FIG. 1 for each case. First, a non-lock type switch (FIG. 3A) is used as the toilet / bath call sensor 170, and the sensor input circuit I is used.
A case where P is used without the operation holding function will be described.

Regarding the state of each setting switch, since this sensor is an ON type sensor, the ON / OFF type setting switch SW1 is ON, and the sensor input circuit IP is used without the holding function, so that the holding / non-holding type setting switch SW2 is used. Is ON, and the function setting switch SW4 is OFF to set the sensor input circuit IP for the toilet / bus call sensor. The toilet / bath call sensor 170 is constantly monitored and the CP
The output port PO1 of U10 is at the voltage level "H".
Therefore, the power-on circuit C1 is operating.

When the sensor S operates in such a state, the switch of the sensor S is turned on. At this time, the currents are the power supply Vcc, the collector of the transistor Q6 of the power-on circuit C1, the base of the transistor Q7 of the signal detection circuit C2, the resistors R11 and R10, the transistor Q4 of the ON-type current limiting circuit C6, the diode D2, and the diode D1. , Terminal M, sensor S, and terminal C. Since this current sufficiently biases the transistor Q7 of the signal detection circuit C2,
To output a voltage to the collector of transistor Q7, C
The input port PI1 of the PU 10 is at the voltage level "H". The CPU 10 detects this and operates both the alarm display device 7 and the speaker 3 to issue an alarm. In this case,
The sensor S is a non-locking switch, and the sensor input circuit IP does not have a holding function. Therefore, the alarm operation is limited to the period when the sensor S is operating.

Next, a case will be described in which a non-lock type switch is used as the toilet / bath call sensor 170 and the sensor input circuit IP has an operation holding function. Regarding the state of each setting switch, the ON / OFF setting switch SW1 is ON, the holding / non-holding setting switch SW2 is OFF, and the function setting switch SW4 is OFF. The function setting switch S is used to operate the holding function by operating the holding circuit C3 of the sensor input circuit IP.
Since it is different from the above case only in that W2 is off,
The process leading to the alarm operation is the same as in the above example. However,
In this case, since the sensor input circuit IP has a holding function, the base of the transistor Q8 of the holding circuit C3 is biased by the voltage of the collector of the transistor Q7 of the signal detection circuit C2, and the transistor Q8 is turned on. As a result, the base of the transistor Q7 is biased by the path of the diode D7 and the resistor R13, and the alarm operation can be maintained.

Therefore, the alarm operation is continued unless the alarm operation is canceled by operating the operation switch SW3. When the operation switch SW3 is closed to release the alarm operation, CP
Since the input port PI2 of U10 is grounded, the voltage level becomes "L" for a certain period of time (for example, 500 milliseconds). As a result, the CPU 10 sets the output port PO1 to the voltage level "L". Therefore, the transistors Q9 and Q9 of the power-on circuit C1
Since both Q6 are turned off, the transistor Q7 of the signal detection circuit C2 is also turned off, and no current flows to the holding circuit C3, so that the holding operation is released, and the input port PI1
Attains the voltage level “L”.

Since the operation switch SW3 is a non-lock type switch, the contact is released after a certain period of time, and the input port PI2 and the output port PO1 of the CPU 10 are released.
Returns to the voltage level “H”. Next, a lock type switch (FIG. 3)
A case where the sensor input circuit IP is used without the operation holding function using the method (b) will be described. Regarding the state of each setting switch, the ON / OFF type setting switch SW1 is ON because the sensor S is ON type, and the holding / non-holding type setting switch SW2 is used because the sensor input circuit IP is used without the holding function. On, the function setting switch SW4 is off to set the sensor input circuit IP for the toilet / bus call sensor, which is the same as the first example. Therefore,
The process leading to the alarm operation is the same as in the first example. However,
Since the sensor S is a lock-type switch, the alarm operation continues unless the sensor S is unlocked on the sensor S side even if the sensor input circuit IP does not have a holding function. It goes into a standby state.

Next, a case where a self-holding type (FIG. 3C) is used as the toilet / bath call sensor 170 will be described. In this type of sensor, the sensor itself has a holding function in a circuit, so that the sensor input circuit IP has a holding function as a whole even if it does not have a holding function. For the status of each setting switch, ON type / OFF
The type setting switch SW1 is on, the holding / non-holding type setting switch SW2 is on, and the function setting switch SW4 is off, which is the same as in the first example. Therefore, the process leading to the alarm operation is the same as in the first example. In this case, since the sensor S itself has a holding function, the input port PI1 of the CPU 10
Is maintained, and the alarm operation is continued until it is released by operating the operation switch SW3. The release by the operation switch SW3 is as described above.

Next, a case where an ON-type sensor (FIG. 3D) is used as the security sensor 160 will be described. In this case, the sensor input circuit IP is used in a state having a holding function. Therefore, for the state of each setting switch,
ON / OFF setting switch SW1 because it is an N-type sensor
Is ON, the holding function of the sensor input circuit IP is operated, so the holding / non-holding setting switch SW2 is OFF, and the function setting switch SW4 is ON for the security sensor sensor input circuit IP. The security sensor 160 is normally in a non-monitoring state, and the output port PO1 of the CPU 10 is at the voltage level "L". When the first operation of the operation switch SW3 is performed, the voltage level of the output port PO1 becomes "H" after 30 seconds, and the power-on circuit C1 is operated to be in the monitoring state. Since the sensor S is an ON type sensor, the switch closes (turns on) when the sensor S operates. At this time, the current is supplied to the power supply Vcc, the collector of the transistor Q6 of the power supply circuit C1, the base of the transistor Q7 of the signal detection circuit C2, the resistors R11 and R10, the transistor Q4 of the ON-type current limiting circuit C6, the diode D2, the diode D1, The current flows through the path of the terminal M, the sensor S, and the terminal C, and this current sufficiently biases the transistor Q7 of the signal detection circuit C2.
As described above, the input port PI1 of U10 becomes the voltage level "H" and the alarm display device LED7 and the speaker 3 are operated. Further, since the sensor input circuit IP has a holding function, the base of the transistor Q8 of the holding circuit C3 is biased by the voltage of the collector of the transistor Q7 of the signal detection circuit C2, and the transistor Q8 is turned on. Is biased in the path of the diode D7 and the resistor R13, and the alarm operation can be maintained. Therefore, the operation switch S
The alarm operation is continued unless the alarm operation is canceled by the operation of W3. During the monitoring state, the operation switch SW3
Is operated, the CPU 10 sets the output port PO1 to the voltage level "L", so that the transistors Q9 and Q6 of the power-on circuit C1 are both turned off, and the power-on circuit C1 does not operate and enters the non-monitoring state.

Finally, a case where an OFF type sensor (FIG. 3E) is used as the security sensor 160 will be described.
In this case, the sensor input circuit IP is used in a state having a holding function. Therefore, regarding the state of each setting switch,
ON / OFF setting switch S because it is an OFF sensor
W1 is off, the holding function of the sensor input circuit IP is operated, so that the holding / non-holding setting switch SW2 is off, and the function setting switch SW4 is on to make the sensor input circuit IP for the security sensor. The security sensor 160 is normally in a non-monitoring state, and the output port PO1 of the CPU 10 is at the voltage level "L". When the first operation of the operation switch SW3 is performed, the CPU 10 outputs the output port PO1 after 30 seconds.
Is set to the voltage level "H", and the power-on circuit C1 operates to enter the monitoring state. Since the sensor S is an OFF-type sensor, the switch of the sensor S is opened (turned off) when the sensor S operates. Therefore, when the sensor S is not operated, the terminal M
And the terminal C are short-circuited, so that the bias to the transistor Q2 of the OFF-type signal detection circuit C4 is cut off. On the other hand, since the switch is turned off during the operation of the sensor S, the transistor Q2 is biased, and the transistor Q7 of the signal detection circuit C2 of the collector load of the transistor Q2 is also turned on. Therefore, the input port PI1 of the CPU 10 becomes the voltage level "H" by the collector voltage of the transistor Q7, and the alarm display device 7 and the speaker 3
To work. The release of the alarm and the release of the monitoring state are the same as in the case of the ON-type sensor described above.
