Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a home security device equipped with a test mode for testing whether the device operates normally.

<Prior art> In-house security devices that detect abnormalities in various parts of a house and issue alarms have two modes: an alert mode that puts the device on alert, and a mode that only detects abnormalities other than intrusion, such as fire or gas leaks. It is possible to switch between a release mode for monitoring and a test mode for testing transmission and reception of the device. In this test mode, when an abnormal signal is received, the abnormality display lamp lights up and an alarm sound is emitted, as in the warning mode, but since the test mode is in progress, the alarm sound is made low, and during the test, An attenuator is inserted into the receiving section of the device to operate at reduced performance.

Therefore, if the user thinks that the device is in the warning mode and leaves it in the test mode, there is a problem in that even if an abnormality occurs, the alarm cannot be alerted or the alarm cannot be heard with a small alarm sound.

Furthermore, when testing by manually lowering the gain of the amplifier in the receiving section, there is an inconvenience that the mode does not operate normally even if the mode is changed to alert mode.

<Objective of the Invention> To solve the drawbacks of the present invention and the prior art described above, to provide a test mode that can sufficiently inform the user when the device is in the test mode, and that does not cause any defects when switching modes. The purpose is to provide an in-house security device equipped with the following functions.

<Configuration of the Invention> The present invention consists of a transmitter placed in various places in the house to transmit detected abnormalities, and a central processor that receives the transmission and issues an alarm.The central processor receives the signal from the transmitter. receive and
a receiving section that amplifies and modulates and outputs a predetermined signal format;
A mode setting section that switches the security state between alarm mode, release mode, and test mode, a microcomputer section that processes signals from the reception section and mode setting section and outputs commands, and generates an alarm sound based on the commands from the computer section. It has an abnormality display section that displays the type of abnormality according to the commands from the computer section, and a sound generating section that generates a sound such as the above, and an abnormality display section that displays the type of abnormality according to the command from the computer section. This is an indoor security device equipped with a test mode, which automatically releases the test state when the mode is switched from one mode to another.

<Embodiment> FIG. 1 is a block diagram showing the entire in-home security device according to the embodiment, FIG. 2 is a front view of the operation panel of the central processing unit, and FIG. 3 is a flowchart of mode switching.

The home security device consists of a plurality of transmitters equipped with anomaly detection sections indicated by M and N, and a central processor that receives the transmissions and issues an alarm. For example, the transmitter is a fire transmitter that detects and transmits the occurrence of a fire, a gas leak transmitter M that detects and transmits a gas leak, an intrusion transmitter N, and a transmitter that transmits other abnormalities at each location. It is installed and transmits abnormalities to the central processing unit using its own code consisting of a house code, a code for each type of abnormality, and a unit code for each transmitter.

The central processor receives the signal from the transmitter, amplifies and modulates it, and outputs it in a predetermined signal format, and a mode setting unit that switches and sets the security state to alert mode, release mode, and test mode. K, and its changeover switch +
, to 2. 3. A computer section A that processes signals from the receiving section G and the mode setting section K and outputs commands, a sound generating section D that emits an alarm sound or a sound that does not allow mode change according to the commands from the computer section A, and a computer section A. Abnormality display part B that displays abnormalities by type according to commands from, and its display lamps bl, b2+ ba..., other display parts such as time C1 Setting switch part E for time and timer, etc., control outlet) F, It has a power outage detection section H1 and a power line 1ift transmission section J. The receiving section G is provided with an attenuator or attenuating means for lowering the reception function and a switch means for connecting the attenuator etc. to the circuit of the receiving section G, and the attenuator etc. is connected to the circuit according to a command from the computer section A. It is possible to turn it on and off.

When the device is in the warning mode, an alarm sound is emitted from the alarm sound generating section in response to a signal indicating an abnormality from the transmitter, and a lamp b1. b2... is lit. When the device is in release mode, only the signal of intrusion abnormality from the transmitter is stored in the computer section A, the alarm sound and indicator lamp are not turned on, and other abnormalities such as gas leak or fire are not detected. Similar to the alert mode, an alarm is sounded and an indicator lamp is lit.

Also, when the device is in the test state, the seat indicator lamp b
l, b2. ba... is made to flash and a test sound is emitted from the sound generating section at regular intervals, and when the receiving section G receives the field thunder signal, the display lamps "bl, b2,
Only the corresponding lamp among b3... is lit for several seconds, and the other lamps are turned off. Also, a test sound is played continuously for several seconds. In addition, in the test mode, since it is necessary to determine the integrity of the operating state of the device by lowering the reception capability of the receiver G than usual, an attenuator or attenuation means is connected to the circuit of the receiver G, and the receiver G is connected to the circuit of the receiver G. I try to work in a state of reduced function. The activation and deactivation of this attenuator or damping means must be switched between the test mode and each mode, but in the present invention, the switching means of the attenuator or damping means is automatically activated by the computer section A when switching modes. The U7 level is designed to be able to perform in a targeted manner. FIG. 3 shows a flowchart of mode change in the apparatus of the present invention. Now press any switch Kl in the mode setting section, 2. When 3 is pressed, computer unit A first determines whether the mode change is to test mode 1', and if it is a change to test mode, it is displayed based on a command from computer unit A. Lamp bl, b2. ba... flashes, a test sound is emitted at regular intervals, the attenuator of the wireless receiver section F is turned on, and the mode shifts to the test mode. On the other hand, if the switching is not to the test mode, then it is determined whether the switching is from the test mode. If yes, display lamp b1. b2
... disappears, the test sound is stopped, the attenuator is turned off, and the test state is released. If no, it is further determined whether or not to switch to alert mode, and if yes, the mode shifts to alert mode, and if no, shifts to release mode.

<Effects> The present invention has the above-described configuration, and is an indoor security device equipped with a test mode as well as a warning mode, etc. During the test mode, the lamp flashes and a test sound is emitted, so that the user can be informed that the test is being carried out. You can make sure that the information is known. Furthermore, when the mode is switched from test mode to another mode, the test state in test mode is automatically canceled, so there is no possibility of switching to another mode with the abnormal signal reception function degraded. Conventional drawbacks are eliminated. Manipulation of l' of the device is prevented, and the device can always be operated in an appropriate state.
