Definitions
- the invention relates to a wireless communication system in which multiple wireless stations transmit and receive wireless signals by use of radio waves as a medium.
- a fire alarm system involving coordinated operation of multiple fire alarm devices through wireless signal has been proposed.
- multiple fire alarm devices disposed in multiple locations each have a function for detecting the occurrence of a fire and emitting an alarm sound.
- the fire alarm device emits an alarm sound, as well as transmitting information indicating that a fire has been detected, to the other fire alarm devices by a wireless signal. Consequently, not only the fire alarm device at the origin of the fire but also other fire alarm devices in synchronization with the same emit an alarm sound in unison, thereby providing a rapid and reliable notification of the occurrence of a fire.
- a fire alarm system in which a particular fire alarm device, of fire alarm devices belonging to a system, is set as a parent device, the other fire alarm devices are set as subsidiary devices, and the devices operate in coordination in relation to a fire by multi-casting of a fire alarm message and/or other messages from the parent device to the subsidiary devices.
- a fire alarm system is also known, which is constituted by multiple fire alarm devices having the same functions, shape and design, and in which a parent device and subsidiary devices are not distinguishable from one another.
- a fire alarm system of this kind since there is no fire alarm device serving as a parent device, then all of the fire alarm devices each must store registration information which includes the identification codes of all of the fire alarm devices belonging to the system.
- JP2011-65260A discloses a fire alarm system whereby the time taken for registration processing can be shortened.
- the fire alarm device after completing registration processing in a fire alarm device, transmits from its own wireless transmission and reception unit by multi-cast a wireless signal including registration information after the registration processing, and all of the other fire alarm devices store the registration information.
- JP2010-049625A discloses a wireless communication system wherein the registration processing is triggered by a first station and carried out automatically by exchanging wireless messages with the other stations to be registered to the group. The registration time can thereby be shortened.
- Document WO 2010/097965 A1 discloses a home security surveillance system having a plurality of terminal detectors one of which functions as a master, and the other function as a slave to constitute an in-house alarm network.
- the in-house network is linked to a server on the side of a service provider to transmit an aid-requesting signal through a gateway unit upon detection of a hazardous condition at each of the terminals.
- Document WO 2012/013692 A1 discloses a method for transmitting sensor data by radio in an alarm system in which secondary stations, which are each coupled to a state sensor, transmit sensor data as well as addresses which identify the secondary stations to a master station.
- Document US 2007/093991 A1 discloses a sensor for monitoring the structural integrity of a building.
- Document EP 2 199 997 A2 an alarm system and an alarm device.
- a fire alarm device operating as a master unit transmits a switching request signal to fire alarm devices operating as slave units at a predetermined timing, the switching request signal containing at least an own address and an address of a fire alarm device that is to operate as the master unit next.
- the present invention has been devised in view of the foregoing circumstances, an object thereof being to provide a wireless communication system which can simplify the work required for registration and can shorten the time required for registration.
- the present invention can carry out registration processing, simply by operating a registration switch of any wireless station just once. Therefore, in the wireless communication system according to the present invention, it is possible to simplify the work required for registration, compared to a case where wireless stations are operated one by one, and furthermore, the time required for registration can be shortened.
- the wireless communication system includes multiple fire alarm devices TR1 to TR3 (in the present embodiment, three fire alarm devices), and wireless signals are transferred (transmitted and received) by radio waves as a medium between the multiple fire alarm devices TR1 to TR3.
- the fire alarm device TR includes a wireless transmission and reception unit 2 configured to transmit and receive a wireless signal via an antenna 1, a fire detection unit 3 configured to detect a fire, a notification unit 4 configured to emit an alarm sound in the event of an abnormality, such as a fire, and a control unit 5 configured to implement controls of various types. Furthermore, the fire alarm device TR includes an operation input reception unit 6 configured to receive operation inputs of various types, and a power source unit 7 configured to supply operating power to each unit by using a battery, such as a dry cell, as a power supply. Unique identification codes are already assigned to the respective fire alarm devices TR in the manufacturing stage. Therefore, each fire alarm device TR can specify the fire alarm device TR that is the addressee of the wireless signal and the fire alarm device TR that is the sender of the wireless signal, by the identification codes.
- the wireless transmission and reception unit 2 transmits and receives wireless signals by use of radio waves as a medium in compliance with "the radio stations of a low-power security system" defined in Article 6, Section 4, Part 3 of the Ordinance for Enforcement of the Radio Law. Furthermore, the wireless transmission and reception unit 2 outputs a received signal strength indicator signal (RSSI signal) which is a DC voltage signal proportional to the intensity of the received signal. "RSSI” is an abbreviation for "Received Signal Strength Indicator”.
- the fire detection unit 3 detects a fire by detecting smoke, heat, flames, or the like, produced by a fire, for example.
- the antenna 1 of the wireless transmission and reception unit 2 may be designed to project from a main body of the fire alarm device TR, as shown in FIG. 2 , or may be designed so as to be built into the main body in such a manner that the antenna 1 is not conspicuous.
- the main constituent element of the control unit 5 is a microcomputer or a rewriteable non-volatile memory (for example, an EEPROM, or the like).
- EEPROM is an abbreviation for "Electrically Erasable Programmable Read-Only Memory”.
- the control unit 5 implements functions of various types by executing a program stored in the memory in a microcomputer. For example, when the occurrence of a fire is detected by the fire detection unit 3, the control unit 5 emits an alarm sound by a buzzer which is provided in the notification unit 4. Alternatively the control unit 5 causes a speaker provided in the notification unit 4 to emit an alarm speech message (such as "Fire! Fire!, etc.) which is previously stored in a memory. In other words, the notification unit 4 reports the occurrence of an event (here, a fire) by speech.
- an event here, a fire
- the control unit 5 transmits a wireless signal including the fire alarm message (called simply "fire alarm message” below), from the wireless transmission and reception unit 2 to the other fire alarm devices TR. Furthermore, when the wireless signal transmitted by another fire alarm device TR is received by the wireless transmission and reception unit 2 and the fire alarm message is accepted, the control unit 5 also controls the notification unit 4 and causes an alarm sound or a speech message to be emitted.
- a wireless signal including the fire alarm message called simply "fire alarm message” below
- the operation input reception unit 6 has multiple switches, such as push buttons, dip switches, or the like, for example.
- the operation input reception unit 6 receives the operation input corresponding to the respective switch due to operation of a switch, and outputs to the control unit 5 an operation signal corresponding to the operation input.
- the operation input reception unit 6 is provided with a registration switch 60 which outputs an operation signal causing the control unit 5 to execute the registration processing described below, upon receiving a predetermined operation input, such as a push operation or a slide operation, or the like (here, a push operation).
- an alarm stop button 60 for stopping the emission of the alarm sound by the notification unit 4 is combined with the registration switch 60.
- the alarm stop button 60 since the alarm stop button 60 is not necessary, then it is possible to reduce the number of switches in the operation input reception unit 6 by combining the alarm stop button 60 with the registration switch 60.
- Registration processing means the processing for registering the fire alarm devices TR to a group for reporting an alarm for coordinated operation of multiple fire alarm devices TR. Firstly, as shown in FIG. 2 , the power supplies to the fire alarm devices TR1 to TR3 are switched on. Thereupon, the control units 5 of the fire alarm devices TR1 to TR3 activate the wireless transmission and reception units 2 and switch to a registration reception mode for continuously waiting to receive wireless signals from other fire alarm devices TR.
- the time period of the registration reception mode is a prescribed time period (for example, 5 minutes) starting from when the power is turned on.
- a prescribed time period for example, 5 minutes
- the time period of the registration reception mode is not limited to the time period indicated above.
- the fire alarm device TR has a so-called tamper function of monitoring about whether the fire alarm device TR is installed on a building surface (the ceiling, or the like), then the time period during which the fire alarm device TR is not installed on the building surface may be set as the time period of the registration reception mode.
- the alarm stop button 60 on any one of the fire alarm devices TR1 to TR3 is pressed.
- the alarm stop button 60 of the fire alarm device TR1 (first wireless station) is pressed.
- the control unit 5 of the fire alarm device TR1 transmits a wireless signal including a registration start message prompting a reply (hereinafter, simply called "registration start message") by broadcasting from the wireless transmission and reception unit 2, continuously for a prescribed period of time.
- the control unit 5 of the fire alarm device TR1 emits a beeping alarm sound by the buzzer of the notification unit 4.
- the control unit 5 of the fire alarm device TR1 activates the wireless transmission and reception unit 2 and switches to a reply waiting mode for waiting for a reply from the other fire alarm devices TR for a prescribed period of time.
- the fire alarm devices TR2, TR3 (second wireless stations) are located inside a range reached by the wireless signal transmitted from the fire alarm device TR1, and therefore are able to receive the registration start message.
- the control unit 5 of the fire alarm device TR2 determines a waiting time period on the basis of the identification code thereof, and then waits for the waiting time period to elapse, starting from the end time of the transmission time period of the registration start message.
- the control unit 5 of the fire alarm device TR2 transmits a wireless signal including a response message which indicates that a registration start message has been received (simply called "response message” below), from the wireless transmission and reception unit 2 to the fire alarm device TR1.
- the fire alarm device TR3 also transmits a response message to the fire alarm device TR1.
- the control unit 5 of that fire alarm device TR does not transmit a response message to the fire alarm device TR1 from the wireless transmission and reception unit 2, even if that control unit 5 receives a registration start message.
- the waiting time period is not limited to the time period described above.
- the fire alarm device TR has a timer for counting the elapsed time after the power supply has been switched on, then the waiting time period can be determined on the basis of the elapsed time counted by the timer.
- a configuration may be adopted in which the control unit 5 of the fire alarm device TR1 divides the reception time period into multiple time slots in the reply waiting mode, and the control unit 5 of each fire alarm device TR2, TR3 transmits a response message to the fire alarm device TR1 using any of the time slots.
- the control unit 5 of the fire alarm device TR1 divides the registration start message into multiple time slots and also divides the reception time period in the reply waiting mode into multiple time slots.
- each fire alarm device TR2, TR3 Upon receiving the registration start message, the control unit 5 of each fire alarm device TR2, TR3 can identify the start point of the reception time period from the number of the time slot at the timing the message was received. The control unit 5 of each fire alarm device TR2, TR3 then generates a random number within the range of the number of divisions of the time slots, and transmits a response message during the reception time period, using the time slot of the number determined on the basis of this random number.
- each fire alarm device TR2, TR3 may perform a carrier sense operation, and after detecting that there are no conflicting radio waves, may transmit the response message to fire alarm device TR1.
- the control unit 5 of each fire alarm device TR2, TR3 may perform a carrier sense operation, and after detecting that there are no conflicting radio waves, may transmit the response message to fire alarm device TR1.
- the control unit 5 of the fire alarm device TR1 stores registration information including the respective identification codes of the fire alarm devices TR which have transmitted the response messages and the identification code of the fire alarm device TR1, in the memory, and individually assigns device numbers to the fire alarm devices TR including the fire alarm device TR1 itself.
- the control unit 5 of the fire alarm device TR1 assigns, for example, the device number "0" to the fire alarm device TR1 itself, assigns the device number "1" to the fire alarm device TR2, and assigns the device number "2" to the fire alarm device TR3. Since the device numbers are well-known, they are not described here.
- the control unit 5 of the fire alarm device TR1 transmits in order from the wireless transmission and reception unit 2 wireless signals each including a registration message (simply called “registration messages” below) to the fire alarm devices TR to which the device numbers have been assigned.
- the control unit 5 of the fire alarm device TR1 activates the wireless transmission and reception unit 2 and waits for a prescribed time period for a reply from the fire alarm device TR to which the registration message has been transmitted.
- control unit 5 of the fire alarm device TR1 transmits registration messages from the wireless transmission and reception unit 2, in order from the fire alarm device having the smallest device number. Consequently, the control unit 5 of the fire alarm device TR1 firstly transmits a registration message to the fire alarm device TR2, from the wireless transmission and reception unit 2.
- the registration message includes the registration information and the device numbers of all of the fire alarm devices TR that have been registered.
- the control unit 5 of the fire alarm device TR2 stores the registration information and the device numbers included in the registration message, in the memory.
- the control unit 5 of the fire alarm device TR2 transmits a wireless signal including a registration response message which indicates that registration has been completed (simply called “registration response message” below), from the wireless transmission and reception unit 2 to the fire alarm device TR1.
- the control unit 5 of the fire alarm device TR2 transfers to an asynchronous intermittent reception mode in which the wireless transmission and reception unit 2 is activated periodically. Since the intermittent reception mode is well-known, this mode is not described here.
- the control unit 5 of the fire alarm device TR1 Upon receiving the registration response message, the control unit 5 of the fire alarm device TR1 subsequently transmits a registration message to the fire alarm device TR3 from the wireless transmission and reception unit 2.
- the control unit 5 of the fire alarm device TR3 stores the registration information and the device numbers included in the registration message, in the memory.
- the control unit 5 of the fire alarm device TR3 transmits a registration response message to the fire alarm device TR1 from the wireless transmission and reception unit 2. Subsequently, the control unit 5 of the fire alarm device TR3 transfers to an asynchronous intermittent reception mode.
- the control unit 5 of the fire alarm device TR1 terminates the registration processing, and then transfers to an asynchronous intermittent reception mode after a lapse of a prescribed time period.
- the control unit 5 of the fire alarm device TR1 causes the speaker of the notification unit 4 to emit a speech message stating "Device registered. There are three registered devices(, including this one)." Accordingly, the installer and/or user can confirm the number of fire alarm devices TR that have been registered.
- the time taken for the registration processing depends on the number of fire alarm devices TR that are to be registered, but is from 5 to 20 seconds.
- the control unit 5 of the fire alarm device TR1 may be configured to repeat a series of operations involving: re-transmission of the registration start message, by broadcasting from the wireless transmission and reception unit 2 after the end of the reply waiting mode; and subsequently switching again to the reply waiting mode, multiple times (for example, three times). By re-transmitting the registration start message in this way, it is possible to raise the probability of receiving response messages from the fire alarm devices TR which are to be registered.
- the control unit 5 of the fire alarm device TR1 measures the RSSI value of the wireless signal received in the reply waiting mode, and if the RSSI value is lower than a previously established threshold value, then re-transmission of the registration start message is stopped.
- this configuration it is possible to determine whether or not registration has been completed for all of the fire alarm devices TR that are to be registered. In other words, if the RSSI value is lower than the threshold value, then it is considered that a wireless signal corresponding to a response message has not been transmitted by any of the fire alarm devices TR that are to be registered. Consequently, with this configuration, it is possible to prevent the time taken for the registration processing from becoming unnecessarily long, since the registration start message is never re-transmitted unnecessarily.
- the control unit 5 of the fire alarm device TR1 transmits a wireless signal including a test message prompting a reply (simply called "test message” below), by multicast from the wireless transmission and reception unit 2.
- the control unit 5 of each of the fire alarm devices TR2, TR3 which belong to the same group transmits a response message to the fire alarm device TR1 from the wireless transmission and reception unit 2.
- the control unit 5 of each fire alarm device TR2, TR3 emits a speech message stating "normal" by the speaker of the notification unit 4.
- the control unit 5 of the fire alarm device TR1 compares the identification codes of the fire alarm devices TR included in the response messages from the fire alarm devices TR2, TR3, with the identification codes of all of the fire alarm devices TR which are stored in the fire alarm device TR1. As a result of this comparison, the control unit 5 of the fire alarm device TR1 confirms that there has been a reply from all of the fire alarm devices TR, and then terminates the test operation. In this case, the control unit 5 of the fire alarm device TR1 emits a speech message stating "normal" by the speaker of the notification unit 4. This test operation can be carried out also after the fire alarm devices TR have been installed on the building surface. In this case also, the alarm stop button 60 of any of the fire alarm devices TR should be pressed in a similar fashion to that described above (see FIG. 2 ).
- the wireless communication system it is possible to implement registration processing for registering respective fire alarm devices TR in a group in which the multiple fire alarm devices TR report an alarm in a coordinated fashion, just by operating the alarm stop button 60 (registration switch) on any one of the fire alarm devices TR, one time. Therefore, in the wireless communication system according to the present embodiment, it is possible to simplify the work required for registration, compared to a case where the fire alarm devices TR are operated one by one, and furthermore, the time required for registration can be shortened.
- the power supplies to the fire alarm devices TR1 to TR3 are switched off. Thereupon, the power supply to the fire alarm device TR1 is switched on, while depressing and holding the alarm stop button 60 of the fire alarm device TR1. Accordingly, the control unit 5 of the fire alarm device TR1 switches to an erasure mode for erasing the registration information. In this case, the control unit 5 of the fire alarm device TR1 emits a "beep" alarm sound by the buzzer of the notification unit 4.
- the control units 5 of the fire alarm devices TR2, TR3 are switched to an erasure mode.
- the alarm stop button 60 of the fire alarm device TR1 is depressed and held within a prescribed time period (for example, several seconds) after switching on the power supply. Accordingly, the control unit 5 of the fire alarm device TR1 erases the registration information which is stored in the memory. In this case, the control unit 5 of the fire alarm device TR1 causes the buzzer of the notification unit 4 to issue a "beep" alarm sound, and also causes the speaker of the notification unit 4 to emit a speech message stating "erased".
- the registration information is erased by the control units 5 of each fire alarm device TR2, TR3.
- the wireless stations of the wireless communication system according to the present embodiment are not limited to the fire alarm devices TR described above.
- the wireless communication system of the present embodiment may be constructed by using wireless stations other than the fire alarm devices TR.
- the wireless communication system by using a wireless station having an air quality sensor configured to measure the so-called air quality, such as the humidity in the air.
- a gas sensor is one example of the air quality sensor.
- a gas sensor measures the gas content of fuel gas, such as town gas, LP gas, or the like, or the COx gas content which is an environmental indicator, such as carbon dioxide and/or carbon monoxide, or dirt, such as dust, which is floating in the air, etc.
- a gas alarm configured to report the occurrence of a gas leak and/or incomplete combustion, by an alarm sound, is an example of a wireless station which includes this gas sensor.
- the wireless communication system according to the present embodiment may also be constructed by using a wireless station which has a human sensor configured to detect the presence of a human.
- the human sensor may employ a system which detects the presence of a human by detecting infrared radiation emitted from a human or a system which detects the presence of a human by image processing analysis of an image captured of a target region.
- both of the abovementioned systems may be used in combination in a human sensor.
- a wireless station having this air quality sensor and/or a wireless station having a human sensor may be combined with a wireless fire alarm device TR described above to construct a wireless communication system.
- a wireless communication system which combines the objects of detecting people and/or issuing ventilation warnings, in addition to detecting fires.
