Description

The present invention relates to a residential fire alarm system, and in particular, performs a predetermined alarm by performing arithmetic processing based on both the ambient environment information signal and the operation signals output from a plurality of fire detection units having different operation principles. The present invention relates to a residential fire alarm system that can reduce false alarms as much as possible and is safe for the user.

Conventionally, there are two types of residential fire alarms: a smoke-type residential fire alarm that emits an alarm when smoke is generated and a thermal residential fire alarm that senses and alerts the surrounding heat. was there.

Smoke-type residential fire alarms have the advantage that they can be alarmed by the smoke of the initial fire, but have the disadvantage that they may malfunction due to, for example, smoke during cooking or smoke from cigarettes. In addition, a thermal fire alarm for homes has the merit that when a fire breaks out, even if there is no smoke, it can be alarmed by the heat of the fire, but it will alarm until the ambient temperature rises to a predetermined temperature. There is a demerit that alarm generation may be delayed because it is not output.

A thermal composite type house fire alarm is known as a supplement to the drawbacks of the smoke type house fire alarm and the thermal house fire alarm (see, for example, Patent Document 1).

The fire alarm for residential buildings described in Patent Document 1 includes a smoke detector and a heat detector, and can detect both the generation of smoke and the detection of heat. In addition, if an alarm is mistakenly generated by detecting smoke such as cooking, the alarm is stopped by pressing an acoustic stop switch, and then the operation is resumed even if smoke is detected for a predetermined time. It works only with heat.

Therefore, when the fire alarm for residential buildings is installed in the kitchen, when cooking, etc., it operates by detecting smoke, and when the user determines that there is no fire, the sound is stopped. The alarm can be intentionally stopped by pressing the switch, and the fire monitoring is continued only with the heat detection unit until the factor that emits smoke such as cooking ends, and smoke detection is again after a predetermined time. The fire can be monitored by the heating part and the heating part.

In FIG. 2, the flowchart which shows operation | movement of the fire alarm system 1 for this house is shown. The flowchart shown in FIG. 2 shows a case where the operation is performed by determining whether or not the surrounding environment information is based on the environment information generating smoke.

First, when the ambient environment information is selected by the user and the ambient environment information signal is input (step S001), the signal processing unit 102 determines whether the input ambient environment signal is based on cooking or tobacco that generates smoke. If it is based on cooking that generates the smoke (step S002), the output signal from the second fire detection unit 105, that is, the heat detection unit is validated (step S003) and the fire monitoring is continued. (Step S005). In step S003, even if there is an output signal from the first fire detection unit 104, the output signal from the first fire detection unit 104 is ignored.

In step S002, when the ambient environment information signal is not based on cooking that generates the smoke (use of a stove or the like), the output signal from the first fire detection unit 104, that is, the smoke detection unit is validated. (Step S004) The fire monitoring is continued (Step S005). In step S004, even when there is an output signal from the second fire detection unit 105, the output signal from the second fire detection unit 105 is ignored.

When the user finishes the action such as cooking and releases the mode selected by operating the release operation unit provided in the ambient environment information selection unit 101, a release signal is sent to the signal processing unit 102. Is output (step S006).

When the signal processing unit 102 receives the release signal, the signal processing unit 102 validates the output signals from both the first fire detection unit 104 and the second fire detection unit 105. (Step S007) The fire monitoring is continued (Step S008).

In other words, in the selected ambient environment information, the operation is performed with the output signal from the fire detection unit (fire detection unit having an operation principle unsuitable for the selected ambient environment) being slowed down as valid. When the signal processing unit 102 receives the release signal, the output signals from both the fire detection units 105 of the first fire detection unit 104 and the second fire detection unit 105 are validated after a predetermined time. You may set to do.

FIG. 3 shows an example of using a data table associating ambient environment information data with whether or not it is valid when output signal data is output from the fire detection unit, as a second embodiment. . ○ means valid, x means invalid.

The signal processing unit 102 stores in advance the ambient environment information-fire detection unit correspondence data in which the ambient environment information data and the effective fire detection unit are associated with each other. When an ambient environment information signal is output, or when an output signal is output from a fire detection unit, the program can refer to the ambient environment information-fire detection unit correspondence data from a predetermined fire detection unit. It is configured to operate with only the output signal of the above as valid. The data table in which the ambient environment information data is associated with whether or not it is valid when output signal data is output from the fire detection unit is an example, and is valid with the ambient environment information data. You may comprise so that various combinations with the output signal data from a fire detection part can be changed.

FIG. 4 shows a flowchart of the operation of the fire alarm system for homes when referring to the data table.

First, when the ambient environment information is selected by the user and the ambient environment information signal is input (step S101), the signal processing unit 102 refers to the data table (step S102), and from the fire detection unit to be validated. The output signal is determined (step S103), and the fire monitoring is continued (step S104).

Next, when there is an output signal from the fire detection unit while monitoring the fire (step S105), it is determined whether the output signal is an output signal from the fire detection unit to be valid (step S106). In the case of the output signal from the fire detection unit to be validated, an alarm generation signal is generated (step S107), and in the case of the output signal from the fire detection unit that is not valid, the process returns to step S104 to fire. Continue monitoring.

Next, if there is a release signal while continuing to monitor the fire (step S108), the output signals from the first and second fire detectors are validated (step S109), and the fire monitoring is continued. (Step S110). When the signal processing unit 102 receives the release signal, the output signals from both the fire detection units 105 of the first fire detection unit 104 and the second fire detection unit 105 are validated after a predetermined time. You may set to do.

FIG. 5 shows an example in which a data table configured by adding an alarm type column and a message data column to the data table in FIG. 3 is used as the third embodiment.

The alarm type column is related to the valid fire detection unit column, and is divided into three types of data of type 1, type 2, and type 0. Each type 1 indicates an operation of the second fire detection unit, that is, indicates that a fire detection by heat has been performed. Type 2 indicates the operation of the first fire detection unit, that is, indicates that fire detection by smoke has been performed. Type 0 indicates that a release signal has been input.

The signal processing unit 102 stores alarm data corresponding to the type data in advance, and changes the alarm generated from the alarm generation unit according to the difference in the type data.

The message data column is related to the column of the ambient environment information data, and various message data corresponding to the ambient environment information data is set.

Next, the alarm type data and message data will be specifically described.

When the type is 1, since there is an output signal from the thermal fire detection unit, the signal processing unit 102 says “temperature rise is detected” among the alarm data stored in advance. Select alarm data.

When the type is 2, since there is an output signal from the smoke type fire detection unit, the signal processing unit alarms that “the occurrence of smoke has been detected” among the alarm data stored in advance. Select data.

When the type is 0, the signal processing unit selects alarm data “selected ambient environment information has been released” from alarm data stored in advance.

For message data, the ambient environment information data
If it is "cooking / baking",
If it is “cooking / stirring”, “during stir-cooking mode”
If it is “cooking / simmering”, “during stew cooking mode”
If it is “cooking and fried”, “during fried cooking mode”
If it is "cooking / oven", "during oven cooking mode"
If it is "cigarette", "during cigarette mode",
If it is “Stove”, “In Stove Mode”,
If it is “Release”, “Continue monitoring”,
Message data is set.

The signal processing unit 102 stores message data “please confirm the occurrence of a fire” in advance.

Then, the arithmetic processing in the signal processing unit combines the alarm data and the message data according to the operation flowchart shown in FIG. 2 or FIG. , “An increase in temperature was detected during grill cooking mode. Check for fire.”.

As described above, the alarm notified from the alarm generation unit is made different depending on the plurality of fire detection units 104 and 105 having different operation principles that have detected the fire and the surrounding environment information data. Can specifically grasp the situation at the time of the alarm occurrence, makes it easier to accurately think about the next action to be taken, and can take action quickly.

Next, as a fourth embodiment, FIG. 6 shows an example using an electromagnetic cooker that is mainly used in a kitchen as a predetermined device and may generate smoke or steam depending on the contents of cooking. Yes.

Reference numeral 400 denotes an electromagnetic cooker, and the electromagnetic cooker 400 is provided with an output unit 401 that outputs an operation signal indicating an operation state in conjunction with turning on / off the power of the electromagnetic cooker 400. .

The operation signal is configured to be input to the ambient environment information selection unit 101. In this embodiment, when the operation signal is input to the ambient environment information selection unit 101, the signal processing unit 102 Is determined to be in the cooking mode, and the operation is performed with the signal from only the second fire detection unit 105, that is, the thermal fire detection unit being valid.

When the use of the electromagnetic cooker 400 is finished and the power of the electromagnetic cooker 400 is set to “OFF”, the output of the operation signal is stopped, the input signal to the ambient environment information selection unit 101 disappears, and the signal The processing unit 102 operates by making output signals from both the first fire detection unit 104 and the second fire detection unit 105 valid.

Next, in FIG. 7, as a fifth embodiment, instead of the output unit 401 that outputs an operation signal indicating an operation state in conjunction with turning on / off the electromagnetic cooker 400 of FIG. 6, The example using the current sensor 402 is shown as a means to grasp | ascertain the operation state of this electromagnetic cooker. An example is shown in which an electromagnetic cooker 400 is connected to the branch circuit of the residential distribution board 10 and a current sensor (CT) 402 using a current transformer is provided on the secondary side of the branch circuit. Yes.

The current sensor 402 outputs an output signal based on the current flowing through the electric circuit, and the output signal is input to the ambient environment information selection unit 101. The output signal of the current sensor may be a current signal, or a voltage signal may be extracted by providing a resistor at the output end of the current sensor.

Regarding the operation, as in the example of FIG. 6 described above, when the operation signal is input to the ambient environment information selection unit 101, the signal processing unit 102 determines that it is in the cooking mode, and detects the second fire. The operation is performed with the signal from only the unit 105, that is, the thermal fire detection unit being valid.

When the use of the electromagnetic cooker 400 is finished and the power of the electromagnetic cooker 400 is set to “OFF”, the output of the operation signal is stopped, the input signal to the ambient environment information selection unit 101 disappears, and the signal The processing unit 102 operates by making output signals from both the first fire detection unit 104 and the second fire detection unit 105 valid.

Next, in FIG. 8, as a sixth embodiment, instead of the output unit 401 that outputs an operation signal indicating an operation state in conjunction with the turning on / off of the power of the electromagnetic cooker 400 of FIG. 6, The example using the electromagnetic wave detection means 403 is shown as a means to grasp | ascertain the operation state of this electromagnetic cooker.

The electromagnetic cooker 400 generates an electromagnetic wave having a specific frequency during cooking, for example, a frequency of 20 kHz, and an electromagnetic wave detecting means (for example, a sensor formed by a coil) for detecting the electromagnetic wave having the specific frequency is used as the electromagnetic cooking. It is provided close to the cooker 400 and monitors the operating state of the electromagnetic cooker 400.

When detecting the electromagnetic wave having the specific frequency, the electromagnetic wave detecting means 403 determines that the electromagnetic cooker 400 is operating and outputs an output signal toward the ambient environment information selecting unit 101.

Regarding the operation, as in the example of FIG. 6, when the operation signal is input to the ambient environment information selection unit 101, the signal processing unit 102 determines that the cooking mode is set, and the second fire detection unit 105. In other words, the operation is performed with the signal from only the thermal fire detection unit valid.

When the use of the electromagnetic cooker 400 is finished and the power of the electromagnetic cooker 400 is set to “OFF”, the output of the operation signal is stopped, the input signal to the ambient environment information selection unit 101 disappears, and the signal The processing unit 102 operates by making output signals from both the first fire detection unit 104 and the second fire detection unit 105 valid.

The ambient environment information selection unit 101 may be configured to receive an output signal from a gas use sensor. A gas meter, a flammable gas detection sensor, or the like may be used as the gas use sensor. By using an output signal from the gas meter or the flammable gas detection sensor to the ambient environment information selection unit 101, it is possible to use the gas. Along with this, it can be configured to automatically stop the operation of a predetermined fire alarm. Thus, you may comprise so that the use condition of apparatuses other than an electromagnetic cooker can be grasped | ascertained. Further, these sensors may be used in combination, and input to the ambient environment information selection unit.
