Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a plurality of abnormality detection means, such as an intrusion detector and a smoke detector, which detect intrusion through windows, doors, etc. inside a house, a building, etc. This relates to a security system that is installed to notify when an abnormality occurs, such as an intrusion through a window, door, etc.

[Prior art]

Conventionally, there has been a system of this type having a configuration as shown in FIG. In FIG. 1, l is a receiver constituting a central control panel, 2 is an antenna for receiving radio waves attached to the receiver 1, 3.4.5 is a mode center switch, and 6
．． 7.8. is the mode display lamp, 9 is momentary
Lock, 10 is the key for lock 9, 11, 12.13 is N
The axis display lamp 14 is a buzzer built into the receiver 1. The alarm display lamp 11.12.13 and the buzzer 14 constitute an abnormality notification means, and the mode set switch 3.4.5 and the mode display lamp 6.7.8
This constitutes a mode switching means. Further, 15 is a smoke detection transmitter. Reference numeral 16 denotes an intrusion detection transmitter, which includes an indicator lamp 17 that indicates that transmission is in progress, a reed switch 18, and a magnet 19, and a lead wire 20 that connects the reed switch 18 and the intrusion detection transmitter 16.

21 is a medical emergency transmitter, and a transmission switch 22
and an indicator lamp 23 that indicates that transmission is in progress.

Each transmitter 15, 16.21 has a built-in transmitting antenna, and when the smoke detection transmitter 15 detects smoke, it starts transmitting, and when the receiver l receives this, the indicator lamp 11 lights up. Buzzer 14 sounds. Intrusion detection transmitter 1
At 6, a magnet 19 is attached to an opening/closing window or door, and a reed switch 18 is attached to a nearby wall. When the window or door opens, the magnet 19 separates from the reed switch 18, so the reed switch 18 operates and the intrusion detection transmitter 16 starts transmitting. In this case, if the intrusion detection transmitter 16 continuously transmits while the window or door is open, the battery will be consumed quickly, so by transmitting for several seconds every minute, the intrusion detection transmitter 16 can detect that the window or door is open. It is something to inform. Note that batteries are used for ease of use and to save wiring work. receiver 1
When it receives the signal from the transmitter 16, the display lamp 12 lights up and the buzzer 14 sounds. Medical emergency transmitter 2
1 starts transmission when the transmission switch 22 is pressed,
When the receiver 1 receives this signal, the display lamp 13 lights up and the buzzer 14 sounds. Receiver 1 also has "daytime",
There are "night" and "going out" selection modes, and these modes are operated by selection switches 3.4.5 and momentary key lock switches 9 and 10. For example, "daytime"
To set the mode, press the switch 3, insert the key 10, turn the lock 9, the display lamp 6 will light up, and the mode is set to "daytime", and then the mode will be set to "night". To change cents, insert the key 10 into the lock 9, turn the lock 9 to turn off the indicator lamp 6, press the switch 4, turn the lock 9 again with the key 10 to turn the indicator lamp 7 on, ``Night'' mode becomes cent complete. [Night]
The same method as above is used when switching from the mode to the "going out" mode. And "daytime" and "nighttime".

Each "going out" function disables only the signal from the intrusion detection transmitter 16 when in the "daytime" mode.
2 and the buzzer 14 do not issue an alarm. Also,"
When in the "Night" mode, an alarm is issued for all received signals. In the "going out" mode, only reception from the intrusion detection transmitter 16 is disabled for one minute after the mode is set, and no alarm is issued. In other words, this one minute is the time for going out. Next, after the one minute period has elapsed, the period of absence begins, and the window is opened and the intrusion detection transmitter 16
If a signal is received from
After a few seconds, a warning is issued by the display lamp 12 and buzzer 14. At this time, the intruder was the person who set up this system (
If the user is a householder), by changing from the "going out" mode to another mode during the 45 seconds, the alarm will no longer be issued. Note that the key 10 is used to prevent the mode from being intentionally switched due to intrusion or the like.

FIG. 2 is a circuit block diagram of the system shown in FIG. 1. In FIG. 2, 24 is a switch unit that operates and starts transmitting when smoke is detected. 25 to 27 are transmitting antennas built into each transmitter. Smoke detection transmission N15. Intrusion detection transmitter 16. Medical emergency transmitter 1
4, when the sensor unit senses each, the transmission switch 24°18.22 operates. This causes the encoding circuits 24a, 18a, and 22a to operate, creating a different code for each transmitter and transmitting circuits 24b and 18b.

22b to transmit data. In the receiver 1, a receiving circuit 1a receives the signal via an antenna 2, and the received signal is sent to each transmitter 24b by a code identification circuit 1b.

The codes from 18b and 22b are analyzed to identify which transmitter the signal was sent from, and the results are controlled via the switch lamp control circuit 1c and the lamp buzzer drive circuit 1d. Further, the lamp buzzer drive circuit 1d controls each alarm display lamp 11, 12, 13 and the buzzer 14 in the above-mentioned mode based on the signal from the switch 3, 4, 5 for the motor center. For example, when the switch 3 is pressed to enter the "daytime" mode, even if the intrusion detection transmitter 16 is activated, it is disabled. This is because there is no need to generate an alarm even if a window or door is opened during the daytime. In addition, each switch 3
．． The signal from 4.5 is generated when lock 9 is rotated.

However, according to this system, when changing from "daytime" mode to another mode, the following problem occurs if the window or door where the intrusion detection transmitter 16 is installed has already been opened. .

That is, when switching to the "night" mode, the received signal from the intrusion detection transmitter 16 becomes valid and an alarm is suddenly issued. In particular, when switching to the "going out" mode, an alarm will be issued 45 seconds after receiving a signal after the one minute time limit for going out. In other words, if the user leaves the window or door where the intrusion detection transmitter 16 is installed open, an alarm will be issued immediately after leaving the house.

[Summary of the invention]

The present invention has been made in order to eliminate the drawbacks of the conventional ones, and includes a display means for monitoring signals from something that is disabled based on the mode switching means, such as an intrusion detection means, so that the operating state of the means can be determined. This is to call attention to the operation of the mode switching means.

[Embodiments of the invention]

3 and 4 are a perspective view and a block diagram showing one embodiment of the security system according to the present invention, and FIG.
The same reference numerals are used for the same or corresponding parts as in FIG. In each figure, the receiver 100 is provided with an indicator lamp 28 for window and door monitoring. This indicator lamp 2
8 is controlled by a timer control circuit 29 via a lamp drive circuit 30. That is, the indicator lamp 28 is normally lit, and turns off when it receives a signal from the intrusion detection transmitter a16, indicating that the window or door is open.

The operation of the security system with such a configuration will be explained using FIG. 5. When the window or door in which the intrusion detection transmitter 16 is installed is opened, a coded signal is output every period T1 for a time T2 shown in FIG. 5 during that time. In this embodiment, time TI is 1 minute and T2 is 4 seconds. When the receiver 100 receives the signal from the intrusion detection transmitter 16, the window and door monitor display lamps 28 are immediately turned off via the timer control circuit 29 and the lamp drive circuit 30, and the timer control circuit 29 starts counting the time Tl+α immediately when the window and door are closed and the received signal at time T2 disappears. In this example, the time α is 2 minutes. While the window or door is open, time T2 is transmitted every time period T1, so the timer control circuit 29 clears the incremented time every time it receives a signal, and resets the time when no received signal is received. This starts counting up T1+α. Then, when the window or door is closed, the intrusion detection transmitter 16 stops transmitting, so the reception signal on the receiver l side disappears, and the timer control circuit 29
When 1+α is counted up, the window and door monitor display lamps 28 are turned on via the lamp drive circuit 30. Therefore, according to this embodiment, by checking that the window/door monitor display lamp 28 is turned off, it can be determined whether the window or door is open, and therefore the mode is changed from "daytime" to "nighttime" or "going out" mode. It is possible to call attention to the switching of Therefore, if windows and doors are open, the mode is switched after closing them.

In addition, in the present invention, an actuator 40 is provided which is controlled by the drive circuit 3o and controls the rotation state of the lock 9, and this actuator 40 causes the lock 9 to move to the key 10 when the light is turned off (when the window or door is open). By preventing the light from rotating and releasing this blocking state when the light is turned on, switching to the above-mentioned mode can be forcibly prevented.

〔Effect of the invention〕

As explained above, according to the present invention, intrusion detection means, etc.
A display means is provided to monitor the signal from the mode switching means which is considered to be invalid based on the mode switching means, and its operating state can be determined. Based on the display contents, the mode switching means is activated, for example, when a window or a door is opened. When you are
It is possible to call attention to the switching from "daytime" mode to "nighttime" or "going out" mode. Therefore, erroneous operation of the mode switching means can be prevented.
