Description

  The present invention relates to an alarm system that detects an abnormality in the external environment and issues an alarm.

Conventionally, as an alarm system that detects an abnormality in the external environment and issues an alarm, a sensor unit that detects a change in the external environment and a microcomputer circuit that determines a change in the external environment based on the output of the sensor unit Was known. As a sensor unit for detecting a change in the external environment, for example, a gas sensor such as an LP gas sensor, a CO sensor, or a fire sensor has been used.
When the sensor unit is, for example, a gas detection element, the microcomputer circuit receives an alarm signal from the microcomputer circuit and issues an alarm by sound when the microcomputer circuit determines that the sensor unit continuously detects the gas to be detected that is above the alarm level. It was composed.

Patent Document 1 describes an alarm device that detects an abnormality such as a fire and issues an alarm, and wirelessly transmits a signal to another alarm device to output an alarm in conjunction with the alarm device.
Specifically, the alarm device has a battery voltage drop below a predetermined value, a predetermined device failure, an abnormality in a transmission / reception circuit unit, an abnormality in wireless communication from another alarm device, a periodic report from another alarm device. When a certain event that cannot maintain normal transmission / reception operation such as a radio alarm stop or other radio alarms is detected, control is performed to stop transmission / reception, decrease transmission power, or stop reception, and send / receive The current consumption of the circuit part was reduced. As a result, even if the function of the linked alarm with other alarm devices by wireless method is lost, the monitoring alarm function of the alarm device can be maintained, and while extending the battery life as much as possible, the alarm-free state can be maintained. It was designed to be avoided as much as possible.

Japanese Patent No. 5307126

The alarm device described in Patent Document 1 has a mode of interlocking alarm in which a plurality of alarm devices are communicated and interlocked. A plurality of alarm devices are usually disposed at different installation locations such as separately disposed in each room of adjacent rooms or separately disposed on different floors in a building. In this case, as long as a plurality of alarm devices are interlocked, each alarm device disposed at a different installation location is informed of the same alarm.
Depending on the type of alarm, for example, there may be a case where only the administrator wants to recognize the alarm sound. In this case, even if the alarm is based on an alarm device provided at a place where the manager is absent, it is convenient if an alarm sound is output only from the alarm device provided at the place where the administrator is present.

  In addition, when the alarm device described in Patent Document 1 detects a predetermined event such as a predetermined device failure, the function of the interlocking alarm that causes a plurality of alarm devices to communicate with each other is lost. Therefore, even if it is necessary to output an abnormality detected by a predetermined alarm device among a plurality of alarm devices as an alarm sound, the alarm sound cannot be output properly, and the user is There is a possibility that the abnormality cannot be recognized.

  Therefore, an object of the present invention is to output an alarm sound from an alarm device different from the predetermined alarm device with respect to a predetermined alarm of the predetermined alarm device when operating a plurality of alarm devices in communication, An object of the present invention is to provide an alarm system capable of outputting an alarm sound even when a device failure of a predetermined alarm occurs.

  An alarm system according to the present invention for achieving the above object is an alarm system that detects an abnormality in the external environment and issues an alarm, and the first characteristic configuration is at least communicable with the parent device and the parent device A result of detection by the parent device side detection means, a parent device side communication means capable of communicating with the child device, and a detection result of the parent device side detection means; Based on the parent device side computing means for calculating the degree of change in the external environment, the parent device side storage means for storing at least a plurality of selectable parent device side alarm sound signals, and the parent device side computing means for alarming If it is determined that a change in the external environment above the level has been detected, a master unit side alarm signal is received from the master unit side arithmetic unit, and any of the master unit side alarm sounds stored in the master unit side storage unit A main unit side alarm means for outputting a signal as an alarm sound; Unlike the master unit detection unit, the slave unit includes a slave unit detection unit that detects a change in the external environment, a slave unit side communication unit that can communicate with the master unit, and the slave unit side detection. A handset side computing means for calculating the degree of change in the external environment based on a result detected by the means, a handset side storage means for storing a plurality of selectable handset side alarm sound signals, and the handset side When it is determined that the calculation means has detected a change in the external environment that is equal to or higher than the alarm level, a slave unit side alarm signal is received from the slave unit side calculation unit, and any slave unit side stored in the slave unit side storage unit A slave unit side alarm means for outputting an alarm sound signal as an alarm sound, and for the predetermined alarm of the slave unit, the slave unit transmits the slave unit side alarm signal to the master unit, and The slave side alarm sound signal is output as an alarm sound by the machine side alarm means. That.

  In this configuration, the predetermined alarm can set any one of the sensors included in the slave unit detection means in the slave unit.

  In other words, with this configuration, the slave unit does not normally issue an alarm based on an abnormality in the external environment detected by the slave unit. A sound signal is output as an alarm sound. Thus, for example, only an administrator recognizes a predetermined alarm by outputting an alarm sound from an alarm device (parent device) different from the predetermined alarm device with respect to a predetermined alarm of the predetermined alarm device (child device). It is considered effective when you want to do it. In this case, even if the alarm is based on an alarm device installed in a place where the manager is absent, if the alarm sound is output only from the alarm device installed in the place where the manager is present, the alarm is immediately responded. It is convenient because measures can be taken.

  According to a second characteristic configuration of the alarm system according to the present invention, when the master unit detects a failure of the master unit side alarm unit, the slave unit side alarm unit performs the slave unit side alarm unit with respect to a predetermined alarm of the slave unit. The alarm sound signal is output as an alarm sound.

  According to this configuration, an alarm based on an abnormality in the external environment detected by the slave unit is not normally performed by the slave unit itself, but only when the master unit, which is another alarm unit, and the master unit side alarm means fails. The handset itself can be configured to output the handset side alarm sound signal as an alarm sound by the handset side alarm means.

  Therefore, the alarm system of the present invention can output an alarm sound based on the abnormality of the external environment by the slave unit even when a device failure of the master unit (failure of the master unit side alarm means) occurs. Therefore, it is possible to appropriately output an alarm sound that should be output and to allow the user to recognize an abnormality in the external environment.

  A third characteristic configuration of the alarm system according to the present invention is that the slave unit side alarm sound signal relating to the predetermined alarm of the slave unit is a simplified message.

  According to this configuration, it is possible to easily identify the normal time and the failure time, and it is possible to reduce the capacity of the slave unit side alarm sound signal related to the predetermined alarm of the slave unit stored in the slave unit side storage means. .

It is the schematic of the alarm system of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The alarm system of the present invention detects an abnormality in the external environment and issues an alarm. As shown in FIG. 1, the alarm system X includes a plurality of alarm device bodies 10. The alarm device body 10 can be a parent device 10a and at least one child device 10b that can communicate with the parent device 10a. In this embodiment, a case where one master unit 10a and one slave unit 10b are provided will be described. For example, the parent device 10a and the child device 10b may be disposed at different locations in the same room, may be separately disposed in each room of an adjacent room, or may have different floors in a building. It may be arranged separately. As will be described below, each of the parent device 10a and the child device 10b is provided with detection means for detecting a change in the external environment.

  The base unit 10a includes a base unit side detection unit 11a that detects a change in the external environment, a base unit side communication unit 12a that can communicate with the slave unit 10b, and a result detected by the base unit side detection unit 11a. The parent device side computing means 13a for calculating the degree of change of the master device, the parent device side storage means 14a for storing at least a plurality of selectable parent device side alarm sound signals S2 in advance, and the parent device side computing means 13a are alarm levels. When it is determined that the change in the external environment has been detected, the parent device side alarm signal S1a is received from the parent device side calculation means 13a, and any of the parent device side alarm sounds stored in the parent device side storage means 14a is received. And a parent device side alarm means 15a for outputting the signal S2a as an alarm sound S3a.

  For example, the base unit 10a is installed on the wall surface by a mounting plate method, and the power source can be an outlet type, but is not limited thereto. When the main unit 10a is an outlet type, communication with the sub unit 10b can be performed at all times.

  As the parent device side detection means 11a, for example, any one of an LP gas sensor, a city gas sensor, a CO sensor, and a fire sensor may be provided. The LP gas sensor can detect LP gas, the city gas sensor can detect leakage gas such as hydrocarbon gas, and the CO sensor can detect carbon monoxide gas generated by incomplete combustion. A type sensor element or a catalytic combustion type gas sensor element can be used. As the fire sensor, a temperature sensor that senses an increase in temperature, a known scattered light smoke sensor having a smoke sensing function, or the like can be used. This embodiment demonstrates the case where it is set as the gas alarm device which applied LP gas sensor as the main | base station side detection means 11a.

  The parent device side communication means 12a may be configured to be able to communicate with the child device 10b by wireless communication or the like, and the wireless communication is preferably bidirectional communication. In the present embodiment, a case where infrared communication is applied as the parent device side communication unit 12a will be described. That is, the base-side communication unit 12a can be configured by an infrared transmission / reception unit.

  The base-side communication means 12a can be configured to change the intensity and frequency of radio waves during transmission / reception. Thereby, when the precision of communication with the subunit | mobile_unit 10b is low etc., the intensity | strength and frequency of a radio wave can be changed and the precision of communication with the subunit | mobile_unit 10b can be improved.

  The parent device side calculation means 13a includes a concentration calculation unit that calculates the LP gas concentration based on the output that the parent device side detection means 11a detects the leakage of LP gas. The concentration calculation unit may use a microcomputer or the like that can calculate the LP gas concentration based on an output signal from the parent device side detection unit 11a.

  The parent device storage unit 14a may be in any form as long as it is a memory or storage capable of storing at least a plurality of types of parent device alarm sound signals S2a. In the present embodiment, a case where a plurality of types of slave unit side alarm sound signals S2b are stored in addition to a plurality of types of master unit side alarm sound signals S2a will be described. In addition to these alarm sound signals, the parent device storage means 14a can store, for example, an identifier (identification number) that can identify each alarm device body 10 (parent device 10a, child device 10b). You may memorize | store the positional information etc. which show an installation place. Moreover, you may comprise the main | base station side memory | storage means 14a so that the identifier signal of self or another alarm device main body 10 can be memorize | stored.

  As a plurality of types of base unit side alarm sound signals S2a, electronic sounds such as “beep, beep, beep, beep,” and synthesized sound signals such as “normal” may be stored. Two or more types of the main unit side alarm sound signal S2a may be stored, and the modes of the synthesized voice and the electronic sound may be other than the above. Other modes include, for example, “Pip, beep, beep, normal. Radio wave is being received.”, “Woo, woo, beep, beep, beep, beep, gas is leaking?”, “ You may be able to say, “Pip, beep, beep, main unit failure.”, “Pip, beep, radio wave cannot be received.”, “Replacement period has expired. Please contact your dealer.” However, the present invention is not limited to these (multiple types of handset side alarm sound signals S2b will be described later).

  When the master unit side arithmetic unit 13a determines that the master unit side detection unit 11a continuously detects the detected gas concentration equal to or higher than the alarm level, the master unit side arithmetic unit 13a determines from the master unit side arithmetic unit 13a. The master unit side alarm signal S1a is received, and an alarm is issued by voice based on the selected alarm sound signal. In the present embodiment, the parent device side alarm means 15a is composed of a speaker and its drive circuit, and a mode in which the parent device side alarm sound signal S2a is converted into an alarm sound S3a and output will be described. However, the present invention is not limited to this. is not.

  Further, the parent device 10a may include a parent device state display means 16a that visually displays the state of the parent device 10a with a lamp or the like. The parent device side state display means 16a can be configured to display, for example, whether or not the power of the parent device 10a is turned on and off, and whether or not LP gas is detected, depending on whether or not an LED lamp is lit.

  By configuring the parent device 10a in this way, when the parent device 10a detects the leakage of LP gas, the parent device 10a outputs an alarm sound S3a by the parent device side alarm means 15a.

  Unlike the main unit side detection unit 11a, the sub unit 10b includes a sub unit detection unit 11b that detects a change in the external environment, a sub unit communication unit 12b that can communicate with the main unit 10a, and a sub unit detection unit 11b. Based on the result detected by the handset side computing means 13b for calculating the degree of change in the external environment, handset side storage means 14b for storing in advance a plurality of selectable handset side alarm sound signals S2b, When it is determined that the machine side computing means 13b has detected a change in the external environment above the alarm level, the slave side alarm means S1b is received from the handset side computing means 13b and stored in the handset side storage means 14b. And a slave unit side alarm means 15b for outputting any slave unit side alarm sound signal S2b as an alarm sound S3b.

  The subunit | mobile_unit 10b is the aspect installed in a wall surface, for example by a hook system, and although a power supply can be made into a battery type, it is not limited to these. This embodiment demonstrates the case where the subunit | mobile_unit 10b is made into a battery type. When the handset 10b is of a battery type, it is preferable that the communication with the base unit 10a is performed intermittently.

  For example, an LP gas sensor, a city gas sensor, a CO sensor, a fire sensor, and a heat stroke sensor may be provided as the slave unit detection unit 11b, but a sensor different from the master unit detection unit 11a is applied. That is, in this embodiment, since the LP gas sensor is applied as the parent device side detection means 11a, a case where a CO sensor, a fire sensor, and a heat stroke sensor are applied as the child device side detection means 11b will be described. It is not limited. As long as the heat stroke sensor can detect temperature and humidity, for example, and can determine heat stroke based on these data, a known sensor can be used.

  The slave side communication unit 12b may be configured to be able to communicate with the base unit 10a by wireless communication or the like, and may have a device configuration according to the above-described base unit side communication unit 12a.

  The slave unit side calculation means 13b includes a concentration calculation unit for calculating the CO gas concentration based on the output and temperature / humidity detected by the slave unit side detection unit 11b detecting leakage of CO gas, smoke, a fire determination unit for determining a fire, A heat stroke determination unit is provided. These concentration calculation unit, fire determination unit, and heat stroke determination unit may use a microcomputer or the like in the same manner as the parent device side calculation means 13a.

  The slave unit storage means 14b may be in any form as long as it is a memory or storage capable of storing a plurality of types of slave unit side alarm sound signals S2b. The slave unit side storage unit 14b may store an identifier, position information, and the like in the same manner as the master unit side storage unit 14a, and may be configured to store the identifier signal of itself or another alarm device body 10.

  As a plurality of types of handset side alarm sound signals S2b, electronic sounds such as “beep, beep, beep, beep,” and a synthesized sound signal such as “normal” may be stored. Two or more types of slave unit side alarm sound signals S2b may be stored, and the synthesized speech and electronic sound modes may be other than those described above. Other modes include, for example, “Woo, Woo, Bippo, Pippop, air is dirty and dangerous. Open the window to ventilate”, “Woo, Woo, Kang, Kang, Kang, Kang, Fire. Fire. "," Pawns, rooms are getting very hot. "," Let ’s be well ventilated and take moisture and salt. " "Pip, battery is dead.", "Pip, beep, radio wave cannot be received.", "Replacement deadline has passed. Please contact your dealer." It is not a thing.

  Moreover, the subunit | mobile_unit 10b may be provided with the subunit | mobile_unit side status display means 16b which displays the state of the subunit | mobile_unit 10b visually with a lamp | ramp etc. The handset-side status display means 16b displays, for example, power on / off of the handset 10b, CO gas detection, presence / absence of fire detection, and warning of heat stroke depending on whether the LED lamps to which these are assigned are turned on / off. Can be configured.

  By configuring the slave unit 10b in this manner, when the slave unit 10b detects leakage or smoke of CO gas, the slave unit 10b outputs an alarm sound S3b by the slave unit side alarm means 15b. At this time, in the alarm system X of the present invention, for the predetermined alarm of the slave unit 10b, the slave unit 10b transmits the slave unit side alarm signal S1b to the master unit 10a, and the slave unit side alarm means 15a transmits the slave unit side alarm. The sound signal S2b is output as an alarm sound.

  The predetermined alarm can set any of the sensors included in the slave unit side detection unit 11b in the slave unit 10b. In the present embodiment, a case will be described in which a heat alarm is notified as a predetermined alarm, but the present invention is not limited to this.

  In other words, with this configuration, the child device 10b does not normally issue an alarm (warning of heat stroke) based on an abnormality in the external environment detected by the child device 10b, but the parent device 10a, which is another alarm device, does not perform itself. The master unit side alarm means 15a outputs the slave unit side alarm sound signal S2b as an alarm sound. As described above, regarding the predetermined alarm of the predetermined alarm device (slave device 10b), by outputting an alarm sound from an alarm device (parent device 10a) different from the predetermined alarm device, for example, only the administrator has heat stroke. It is considered effective when it is desired to recognize a reminder. In this case, even if the alarm is based on an alarm device installed in a place where the manager is absent, an alarm sound (warning for heat stroke) is output only from the alarm device installed in the place where the manager is present. This is convenient because the administrator can immediately take measures such as improving ventilation and adjusting the air conditioning.

  When the master unit 10a detects a failure of the master unit side alarm means 15a, the slave unit side alarm means 15b outputs a slave unit side alarm sound signal S2b with respect to a predetermined alarm (warning of heat stroke) of the slave unit 10b. It is configured to output as an alarm sound. At this time, if the slave unit side alarm sound signal S2b is output as a simple message, the slave unit side alarm sound to be stored in the slave unit side storage means 14b can be easily identified during normal operation and failure. The capacity of the signal S2b can be reduced. Moreover, since power consumption at the time of an alarm can be suppressed by simplification, when the power supply of the subunit | mobile_unit 10b is a battery, battery consumption can be suppressed and battery life can be extended. The simplified message is not particularly limited, and any message may be set as long as the normal message can be simplified and recognized by the user.

  For the failure of the parent device side alarm means 15a, for example, a failure such as disconnection of the parent device side alarm means 15a, which is a speaker, is detected by the failure detection means 17, and is output as a failure determination signal S4 indicating whether or not there is the failure. . For example, the failure detection unit 17 may include a disconnection detection circuit that determines a disconnection by detecting a potential difference between the output terminal of the parent device side alarm unit 15a and a predetermined battery, but is not limited thereto. It is not a thing.

  If the handset 10b receives the failure determination signal S4, the handset side alarm means 15b can issue a heat stroke alarm.

  If it is this structure, the subunit | mobile_unit 10b which does not perform the warning based on the abnormality of the external environment which the subunit | mobile_unit 10b detected (warning of heat stroke) by itself normally will be performed by the main | base station 10a which is another alarm device, The slave unit 10b itself can be configured to output the slave unit side alarm sound signal S2b as an alarm sound by the slave unit side alarm unit 15b only when the master unit side alarm unit 15a fails.

  Therefore, in the case of the alarm system X of the present invention, even when a device failure of the parent device 10a (failure of the parent device side alarm means 15a) occurs, the failure determination signal S4 is transmitted to the child device 10b. Because it is possible to output an alarm sound based on abnormalities in the external environment (warning for heat stroke), it is possible to appropriately output the alarm sound that should be output so that the user can recognize abnormalities in the external environment. .

  In this embodiment, when the master unit 10a detects a failure of the master unit side alarm unit 15a, the slave unit side alarm unit 15b uses the slave unit side alarm unit 15b for a predetermined alarm (warning of heat stroke). The side alarm sound signal S2b is output as an alarm sound. For example, when the slave unit 10b detects a failure of the slave unit side alarm means 15b, other alarms (CO sensor, fire sensor, etc.) ), A backup of the speaker may be configured so that the slave unit side alarm sound signal S2b is output as an alarm sound by the master unit side alarm means 15a.

  In the alarm system X of the present invention, a change in the external environment detected by the parent device side detection means 11a is output as an alarm only by the parent device side alarm means 15a. If the handset 10b is of a battery type as in the present embodiment, it may not be configured to always receive communication from the base 10a from the viewpoint of power consumption. This is because the slave unit 10b cannot always communicate with the master unit 10a, and the slave unit 10b cannot immediately recognize the speaker failure of the master unit 10a.

  INDUSTRIAL APPLICABILITY The present invention can be used for an alarm system that detects an abnormality in the external environment and issues an alarm.
