Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a security device that wirelessly transmits and reports a signal from a sensor that detects fire, intrusion, etc. to the main body.

[Conventional technology]

Traditionally, this type of security equipment has been designed to protect against smoke, heat,
It has a built-in transmitter with built-in sensor functions for detecting fires such as gas, detecting intrusion through windows and doors, and for medical emergencies, as well as a receiver that receives transmissions from each of these transmitters. It consists of a main body equipped with a buzzer and indicator lamp for issuing alarms corresponding to each transmitter, and the main body also has a built-in function for selecting its operating time into daytime, nighttime, and out-of-home modes.

According to the conventional device configured in this way, when the smoke detection transmitter detects smoke, it starts transmitting, and when the receiver of the main unit receives this, the indicator lamp lights up and at the same time the buzzer sounds to alert you to an abnormality. Inform. Similarly, an intrusion detection transmitter sends a signal to the main unit when a window or door opens and an intruder is detected, lights up an indicator lamp and sounds a buzzer, and a medical transmitter can also be used by pressing a switch if necessary. Transmission is performed, and the display lamp lights up and the buzzer sounds. Also, if you set the operating time selection function to "daytime" mode,
It works by disabling only the signals from the intrusion detection transmitter, while when set to "night" mode it will issue an alarm on all incoming signals. Further, in the "going out" mode, only the signal from the intrusion detection transmitter is disabled for a predetermined period of time after setting, for example, one minute, so that no alarm is output. In other words, this "going out" mode is a mode that the user selects when going out, and the one minute period during which the signal is disabled is the time to open the door and go out. After that time has elapsed, the signal from the intrusion detection transmitter becomes valid, and if an intruder opens a window or door, the indicator lamp lights up and the buzzer sounds after waiting for one minute. It is. Therefore, if the user switches the selection function to a mode other than the "going out" mode within one minute before the alarm is issued, the alarm will not be issued.

[Problem that the invention seeks to solve]

Conventional security devices such as those mentioned above
The signal received from the intrusion detection transmitter is disabled for a predetermined period of time when the user goes out, but this time is not very long considering the purpose of the security device itself, so the user must consider when to go out each time. The problem is that the mode has to be changed, and this is also the case when returning from going out, making handling extremely troublesome.

The present invention has been made to solve such problems, and an object of the present invention is to provide a security device that allows the user to arbitrarily set the time for disabling the signal from the intrusion detection transmitter.

[Means for solving problems]

The security device according to the present invention has a dedicated auxiliary device that disables the signal from the intrusion detection transmitter during the period when the operating time mode of the main body is set to the "outside" mode, separately from the intrusion detection transmitter. It is equipped with a transmitter.

[Effect]

In this invention, even if a predetermined period of time for disabling the signal from the intrusion detection transmitter has elapsed after the user sets the out-of-home mode, the user can operate the auxiliary transmitter to reset the signal's disable time. I'm trying to set it up.

[Embodiment]] An embodiment of the present invention will be described below with reference to the drawings.
In the figure, 1 is a main body with a built-in receiver, and an antenna 2 for receiving radio waves is attached. 3,4,5
is a push-button switch located on the top surface of the main body 1 for changing the operating time mode, and consists of three modes: daytime, nighttime, and going out. 6, 7, 8 are mode display lamps corresponding to each push button switch 3, 4, 5;
Numeral 9 is a momentary lock, 10 is a lock key, and 11, 12, and 13 are alarm display lamps arranged on the top surface of the main body 1, which are for fire, intrusion, and emergency. 14 is a buzzer built into the main body 1. 15 is a smoke detection transmitter attached to the ceiling of the room, and has a built-in smoke sensor 27. 1
Reference numeral 6 denotes an intrusion detection transmitter, which includes a reed switch 18 attached to a window frame or door frame, and a magnet 19 attached to the window or door opposite the reed switch.
The reed switch 18 is connected via a lead wire 20. Reference numeral 17 indicates a display lamp indicating that the intrusion detection transmitter is transmitting, and 21 indicates a medical emergency transmitter, which is equipped with a transmitting switch 22 and a display lamp 23 indicating that transmission is in progress. Reference numeral 24 is an auxiliary transmitter for disabling only the signal from the intrusion detection transmitter 16 for a predetermined period of time, for example, one minute, while the mode is set to "going out"; a transmitting switch 25; and an indicator lamp indicating that transmission is in progress. 26. 28, 29, 30, and 31 are wireless transmission antennas built into each transmitter. Further, each transmitter has a coding circuit that can obtain a different code signal, as shown in FIG. 2, and this code signal is transmitted from an antenna. On the other hand, the main unit 1 has a code identification circuit that decodes the received code signal and determines which transmitter it is sent from, and controls the buzzer and indicator lamp based on this identified code. ing.

Next, the effect will be explained. The smoke detection transmitter 15 starts transmitting when it detects smoke in the room, and when the receiver of the main body 1 receives this, the lamp 11 indicating a fire lights up and at the same time the buzzer 14 sounds. When the window or door opens, the intrusion detection transmitter 16 separates the magnet 19 from the reed switch 18.
Since the reed switch is turned on and transmission begins, the intrusion indicator lamp 12 lights up and the buzzer 14 sounds.
If the intrusion detection transmitter continuously transmits data while the window or door is open, the battery will run out quickly, so it transmits data at a rate of several seconds every minute.
Furthermore, when the medical transmitter 21 presses the transmission switch 22 as necessary, transmission begins, the lamp 13 indicating an emergency lights up, and the buzzer 14 sounds.
The operation time selection function provided on the main body 1 is executed by the cooperation of the push button switches 3, 4, 5 and the key 10 of the momentary 9. For example, to set to "daytime" mode, press switch 3, then press key 10.
When the lock 9 is turned, the indicator lamp 6 lights up and the setting is completed. Next, when setting the "night" mode, insert F-10 into lock 9 and turn it, indicator lamp 6 will turn off and switch 4 will turn off.
Press and turn key 10 again, display lamp 7
lights up to let you know that the night mode has been set. Do the same thing when switching from "night" mode to "going out" mode. In the "daytime" mode, the signal from the intrusion detection transmitter 16 is disabled so that the display lamp 12 and buzzer 14 do not issue an alarm, and in the "night" mode, an alarm is issued for all received signals. It's starting to come out.

In the "going out" mode, reception from the intrusion detection transmitter 16 is disabled for one minute after the mode is set, so that no alarm is issued, and this is the time when the door can be opened to go out. However, if you are unable to go out during this time for some reason, sending the auxiliary transmitter 24 will extend the invalid time by an additional minute, but you can use the auxiliary transmitter as necessary. do. After this time has elapsed, all signals from the intrusion detection transmitter 16 will be valid, but if the auxiliary transmitter 24 is transmitted during this time, there will be a time period in which the signal can be disabled for one minute at any time. There is. Therefore, when going in and out of a window or door where the intrusion detection transmitter 16 is installed, if the auxiliary transmitter 24 is operated each time, the person can go in and out without issuing an alarm. Note that in normal times, all signals from the intrusion detection transmitter 16 are valid for the receiver of the main body 1, but when an intruder opens a window or door, the receiver is activated as before. After a waiting time of one minute has elapsed, a display lamp 12 is turned on, a buzzer is sounded, and an alarm is output.

The next time the user returns home from going out, he or she must either cancel the "out" mode setting during the 1-minute standby time after opening the door, or operate the auxiliary transmitter 24 before opening the door. Set an invalid time of 1 minute, open the door and go inside within this time,
All you have to do is cancel the "going out" mode setting.

[Effects of the Invention] As described above, according to the present invention, the auxiliary transmission function disables only the signal received from the intrusion detection transmitter for a predetermined period of time while the operating time of the receiver built in the main body is set to the out-of-home mode. Since the device is equipped with a container, it is easy for the user to operate the device when entering and leaving the device, resulting in an extremely useful device.
