Description

  The present invention relates to an alarm device including a sensor that detects a physical quantity to be detected and an alarm output unit that outputs an alarm when the physical quantity detected by the sensor is equal to or greater than a predetermined value.

  Usually, when an alarm device detects that a physical quantity to be detected, such as a city gas concentration, exceeds a predetermined value, that is, when an abnormality is detected, an alarm is activated to notify the user of the abnormality. In some cases, different alarm operations are performed according to the detected abnormality state, and the user can be informed of what abnormality is occurring depending on the type of the alarm.

  The alarm is only activated when an abnormality occurs. During normal operation, the user must know what kind of alarm is output or what kind of abnormal condition the alarm represents. Therefore, it is necessary to explain the alarm in advance to the user. In addition, for alarm devices that have been in use for a certain period of time, periodic inspections of alarm operations may be required. When newly installing an alarm device so far, or when carrying out a periodic inspection of an already installed alarm device, an abnormal state is actually generated. For example, in the case of a gas alarm device, the gas to be detected for inspection is supplied. The alarm operation was performed by blowing on the sensor part, and it took time to check.

  For this reason, when the power is turned on or when the switch is operated, a plurality of voice messages that inform the alarm contents are sequentially uttered, whereby a gas alarm device that can be explained to the user in advance (for example, Patent Document 1) Reference) is under consideration. Such a gas alarm device has an advantage that it is convenient for explanation because the voice message uttered at the time of abnormality can be actually heard by the user at the time of inspection, and the explanation itself can be easily understood. It is also useful when regularly checking the speech function.

  Similarly, in order to simplify the inspection of the gas alarm device, the inspection of the gas sensor, etc. is omitted during the inspection, and only the alarm operation such as sound, light, alarm signal, etc. is inspected. A gas alarm (for example, see Patent Document 2) that prevents an operation from occurring is also known.

  Conventional alarm devices can easily check whether or not the alarm operation is performed correctly as described above, and can also be used to show and explain alarm information in advance for the user. It was something.

  However, although the alarm action can be easily checked, the sensor detection function, which is one of the important functions of the alarm device, is not checked together with the alarm action function, so the manufacturer guarantees the sensor. For the fixed period of time, it was only exchanged for each warranty period on the assumption that it would function reliably.

  On the other hand, in an alarm device that operates when a sensor detects a physical quantity greater than or equal to a predetermined value, if the actual physical quantity exceeds a predetermined value, is this detected by the sensor and does the alarm operate correctly? The user is anxious about whether or not the physical quantity detected by the sensor matches the actual physical quantity.

  Also, when an alarm is attached, check whether it is attached at an appropriate position, for example, whether it is a position where a physical quantity of a predetermined value or more can be detected immediately when an abnormality occurs. There was no art. For this reason, there is a time lag between the occurrence of an abnormality and the alarm operation, or on the contrary, the daily life is not taken into consideration, and naturally an alarm device is installed at a position where a physical quantity greater than the predetermined value occurs when living a life As a result, there was a case where an alarm was activated even though it was not abnormal.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an alarm device that can easily check the detection function of a sensor and can grasp an appropriate mounting position.

In order to achieve the above object, the first characteristic configuration of the alarm device according to the present invention includes a sensor for detecting a physical quantity to be detected, and an alarm output means for outputting an alarm when the physical quantity detected by the sensor is a predetermined value or more. When provided with a, Oite during inspection operation, and a mode for presenting speech to a physical quantity detected by said sensor in succession at predetermined intervals, said alarm the physical quantity has detected by the sensor as well as presented by voice a mode of presenting the warning information of all kinds with an output unit, in that with switchable information presenting means.
Here, the physical quantity means a sensor output obtained by measuring a general detection target such as temperature, various gas concentrations such as hydrocarbon gas / carbon monoxide gas / hydrogen gas, and smoke concentration.

That is, according to this configuration, during the inspection operation, the physical quantity detected by the sensor is presented, so it is possible to easily check whether the sensor is functioning normally. In particular, since the sensor detects and presents a real-time physical quantity, it can be checked whether the sensor has a correct measurement function by actually measuring the physical quantity .

Also, grasp physical quantities at each position by presenting real-time physical quantities. It is possible to attach an alarm device at an appropriate position. In particular, physical quantities are presented by voice Therefore, it is possible to confirm the physical quantity to be detected while performing other work such as installation work. Yes.

Further, the physical quantity detected by the sensor in co when presented by voice, so presenting alarm information of all types included in the alarm output means and to check the measurement function of the sensor, is possible to check the alarm operation it can.
In addition, explanation to the user becomes easy.

  A second characteristic configuration of the alarm device according to the present invention is that the sensor for detecting the physical quantity is a temperature sensor.

  That is, according to this structure, it is applicable to the fire alarm which detects temperature and outputs an alarm. And since real-time temperature can be presented, for example, when installing a fire alarm in the kitchen, an appropriate installation location such as a position where the temperature does not become too high even if a heat source such as a gas stove is used. Can be selected.

The third characteristic configuration of the alarm device according to the present invention is that it includes a start switch for starting the information presenting means.

  That is, according to this configuration, the physical quantity can be arbitrarily presented by providing the start switch.

It is a schematic block diagram which shows an example of the alarm device which concerns on this invention.

Hereinafter, as an embodiment of an alarm device according to the present invention, a case where it is applied to a fire alarm device in which a physical quantity to be detected is temperature will be described with reference to the drawings.
As shown in FIG. 1, the fire alarm device according to the present embodiment has a temperature sensor 1 that detects temperature, a control unit 2 that controls information detected by the temperature sensor 1, and an alarm based on information detected by the temperature sensor 1. Is provided with an alarm control unit 3 that determines whether or not to output, an alarm output unit 4 that outputs an alarm, and an information presentation unit 5 that presents information detected by the temperature sensor 1 by voice.

  In a normal state where the fire alarm is installed, that is, when the fire alarm is monitoring a fire, the control unit 2 transmits temperature information detected by the temperature sensor 1 to the alarm control unit 3. The alarm control unit 3 determines whether or not the transmitted temperature is equal to or higher than a predetermined value. When the temperature does not reach the predetermined value, the normal state is maintained. When the temperature is equal to or higher than the predetermined value, it is determined that there is a fire, and the alarm output means 4 outputs an alarm. The alarm control unit 3 determines whether or not the temperature is equal to or higher than a predetermined value as described above, but provides a plurality of thresholds and outputs an alarm according to the temperature detected by the temperature sensor 1. It can also be controlled in stages.

  The alarm output means 4 outputs one or more of sound, sound, light, external signal, etc. as an alarm when the alarm control unit 3 determines that a fire has occurred. Correspondingly, the type of sound, how it sounds, the type of voice message, the color of light, how it shines, the presence or absence of an external signal, etc. can be output as an alarm. That is, for example, when alerting the user, output an alarm only with an electronic sound and blinking of the lamp, do not communicate with the outside, and if a fire occurs and it is urgent, While outputting an alarm by voice message, it is also possible to output a signal to the outside by communication so as to inform the user, an external administrator, etc. of the situation.

  In addition, about the structure and function of the fire alarm device in a normal state, it is the same as that of a conventionally well-known temperature detection type fire alarm device.

  When the fire alarm device according to the present embodiment is in an inspection operation, that is, when the real-time temperature information detected by the temperature sensor 1 is presented, the control unit 2 provides the temperature information detected by the temperature sensor 1 as information presentation means. 5

As described above, the control unit 2 transmits temperature information detected by the temperature sensor 1 to the alarm control unit 3 in a normal state. In the inspection state, the temperature information is transmitted to the information presentation means 5. In this case, the control unit 2 can transmit the real-time temperature information detected by the temperature sensor 1 to the information presentation unit 5 at an arbitrary interval.
For example, the control unit 2 can set the inspection state by turning on the power of the alarm device, and can arbitrarily switch between the normal state and the inspection state by operating a start switch (not shown). . Furthermore, a timer may be provided in the control unit 2 so that the control unit 2 can be controlled to be in a normal state after a certain time has elapsed after the power is turned on or the start switch is operated.

The information presenting means 5 presents the specific value by voice based on the transmitted temperature information, and the presentation is continuously performed during the inspection operation at the same interval as the interval transmitted from the control unit 2. .
Since the fire alarm device according to the present embodiment presents the value of the temperature actually detected by the temperature sensor 1, it is possible to easily know whether or not the temperature sensor 1 is functioning normally. Further, it is possible to check whether or not the temperature value detected by the temperature sensor 1 is correct by comparing with the actually measured temperature value. If there is an error between the actually measured value and the value detected by the temperature sensor 1, for example, by providing a correction function in the control unit 2, the temperature information detected by the temperature sensor 1 can be obtained by the control unit 2. It can correct | amend and can transmit exact information to the alarm control part 3 and the information presentation part 5. FIG.
Further, when the alarm device is attached, real-time temperature information at the attachment position can be presented, so that an appropriate attachment position can be grasped.

The fire alarm device in the present embodiment can present all the alarm information included in the alarm output means 4 as well as the temperature information detected by the temperature sensor 1 during the inspection operation. That is, the control unit 2 transmits the temperature information detected by the temperature sensor 1 to the information presentation unit 5 and then instructs the alarm output unit 4 to present all types of alarm information. Thereby, the fire alarm can repeat the presentation of temperature information and the presentation of alarm information during the inspection operation. The presenting of alarm information is not particularly limited as long as all alarm information possessed by the alarm output means 4 can be presented. For example, sound and light can be output simultaneously, or a voice message can be output and a signal can be output externally. Arbitrary settings are possible.
In addition, the fire alarm device according to the present embodiment is provided with a separate switch (not shown) to switch between presenting only temperature information and presenting temperature information and alarm information during an inspection operation. Is also possible.

  Furthermore, the fire alarm device according to the present embodiment can be provided with a bidirectional communication function with the outside, thereby not only outputting a signal to the outside as an alarm as described above, but also an administrator or the like from outside. It is also possible to check and set the vessel.

  The fire alarm device of the present embodiment is configured as described above. Hereinafter, a case where the fire alarm device is attached to a kitchen of a general household will be described as an example. In addition, the following description is about the selection of the installation position of a fire alarm device, and an initial inspection, and is otherwise the same as that of a conventional fire alarm device.

First, a heat source such as a gas stove in the kitchen is put into use. And it sets to the state which can show only temperature information, and turns on the power of the fire alarm. The fire alarm is in an inspected state when the power is turned on.
Take the fire alarm near the planned installation location and check the temperature information presented. For example, if the presented temperature information is extremely high compared to the ambient temperature, the position is affected by a heat source such as a gas stove. It indicates that there is a risk of doing. On the other hand, at the position where the wind of the cooler or fan directly hits, the temperature is lower than the surrounding temperature, indicating that there is a possibility that it may not be detected correctly even in the event of a fire. For this reason, the position of the fire alarm is moved little by little, and an appropriate position is searched based on the temperature information presented at that position.
If the interval for presenting temperature information is set to about 30 seconds to 1 minute, the position can be set efficiently.

After the attachment position is determined in this manner and attached, the setting is switched so that alarm information can be presented together with temperature information.
And after operating a start switch and presenting temperature information, all kinds of alarm information which the alarm output means 4 has are sequentially presented. Thereby, while making the user confirm that the temperature sensor 1 is functioning correctly, it is possible to easily explain the fire alarm device by actually listening to all types of alarm information.

(Another embodiment)
Hereinafter, another embodiment of the alarm device according to the present invention will be described.
In the said embodiment, although it was set as the fire alarm device provided with the temperature sensor 1, it can also be set as the fire alarm device provided with the smoke sensor. Moreover, it can also be used as a gas alarm by using a gas sensor as a sensor. In this case, the information presenting means can present the smoke and gas concentration values.
In addition, the present invention can be applied to an air pollution alarm device provided with a dirt sensor.

  Moreover, the alarm device according to the present invention may include a plurality of sensors, for example, a fire or gas alarm device including a temperature sensor and a gas sensor. In this case, the information presenting means may present only one of temperature and gas concentration or sequentially present both.

  The alarm device according to the present invention can be applied to various alarm devices such as a fire alarm device, a gas alarm device, and a smoke alarm device.
