DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connection method between a sensor and a controller in a home security system.

This is a configuration diagram of a conventional home security system shown in onHome Control Systems*, and in Figure 9, (1) is a security controller;
2) is a display device, and (5) is a sensor transmitter.

Next, the operation of this system will be explained. Transmitter (5
) sends a signal to the security controller (11) when the sensor is turned on.The security controller +11 sends a signal to the security controller (11) to report that the sensor is on.
The status is output to the display (2).

[Problem that the invention seeks to solve]

Conventional security systems are configured as 9 or more, and are based on the premise that a transmitter is connected to a sensor, and a receiver is connected to a security controller.

However, the sensor is not necessarily located far from the security controller, but is often located very close to it.

In addition, in the case of a newly built house, there is no problem in using dedicated wiring, and in this case, it is often very uneconomical to connect a transmitter to each sensor.

In addition, the eight inputs are often provided with three types of sensors for fire, gas, and intrusion, and one type of emergency switch, and the security sensor generates a separate alarm for each, but these three types The arrangement of sensors and switches and security controllers/trawlers in which they are installed.

This varies depending on the design of the house, and for some sensors it is economical to use a wired method, while for others it is often more convenient to use a wireless method.

Furthermore, multiple intrusion sensors etc. are often installed in one room, and any one of these multiple sensors
The configuration is such that an alarm is output if the switch turns on at any time. Further, in this case, some of the plurality of sensors are often arranged close to the security sensor, and the rest are arranged separately. In this case, it is naturally desirable to use a wired sensor and a wireless sensor in combination.

However, with conventional security systems, it has been difficult to obtain the optimal combination of various sensors depending on the house in which the security system is installed.

The present invention has been made to solve the above-mentioned problems, and relates to, for example, an intrusion sensor for one security controller.

Signals from both wireless and wired sensors can be input in common, and in the case of a system configuration that uses only wired sensors, an inexpensive configuration can be easily achieved by removing the elements necessary for the wireless sensor. The aim is to obtain a security system that can be taken.

[Means for solving problems]

In the security system according to the present invention, the security controller is provided with contact input terminals for various sensors, and the receiver output of the wireless sensor is converted into a contact output to match the output form of the wired sensor.

[For production]

This is because the receiver with contact output in this invention can be connected in parallel with the output of a wired sensor.

It becomes possible to use wired and e-wireless sensors simultaneously with one security controller.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (3) is the security controller (1)
wired sensor connected to the input terminal of (4) is the receiver,
(5) is a transmitter, and (6) is a sensor connected to the transmitter +51. Note that (61, (51, +41) form a wireless sensor.

In Fig. 2, 0υ is the security controller processing unit, Oz is the buffer, (13 and Q41 are the connection terminal blocks, (4υ is the receiving circuit, (4 is the amplifier, and (43 is the relay).

1441i light receiving cable # (51) is a transmitting circuit,
(52) is a light emitting element.

Next, the operation will be explained. Wired sensor (3) is ON
Then, this signal is sent to buffer a3 via terminal block 03.
set the output to high level. Then, the security controller processing unit (Ill) knows that the sensor (3) is ON.Secondly, when the sensor (6) is ON, the transmitter (5)
) sends a signal indicating this via the light emitting element (52).

Transmit as infrared.

Next, a light-receiving element connected to the receiver (4) receives this infrared signal and transmits it through an amplifier (43) receiving circuit (4D).

Turn on relay C3. This signal makes the output of buffer Q2 high level through the terminal block 041, so the security controller processing unit aυ turns on the sensor (6).
Know what you did.

As mentioned above, the security controller processing unit aυ is
Which sensor (6) or sensor (3) is ON?
Even if you do, you can know it.

Moreover, when only the sensor (3) or the sensor (6) is used, it is sufficient to simply disconnect the respective terminal blocks (13, 04).

In the above embodiment, the transmitter (5) and receiver (4) are connected? ) Infrared rays were used as the medium, but instead of this, radio waves,
Ultrasound and other media can also be used.

Further, in the second embodiment, a relay is used as the output of the receiver, but an analog switch such as a CMO5IC, a transistor with an open collector output, or the like may be used instead.

〔Effect of the invention〕

As described above, according to the present invention, the security controller is configured so that a wired sensor and a wireless sensor can be connected at the same time, so that one security sensor can be used in a newly built house (using a wired sensor).

It can be used in both existing houses (using wireless sensors), improving versatility. Furthermore, since the receiver is separated from the security sensor, it can be removed if a wired sensor is used, making it possible to construct an economical system.
