Description

The present invention makes it easy for a general user to know how much the detected value of a sensor is, and an alarm-related business operator can confirm the current security or develop an alarm device in the future. The present invention relates to a highly convenient alarm device that can easily know information (state change) from the past to the present of the alarm device, and an alarm device system including such an alarm device .

  In recent years, various alarm devices that include various sensors and detect gas leaks and fires have been developed and put into practical use. These alarms notify the surroundings with a buzzer, lamp, etc. that the physical value of the monitoring target detected by the sensor exceeds a predetermined threshold value, indicating that it is in an abnormal state or is in a state that requires attention. It is configured to do.

  For example, the alarm device is configured as shown in FIG. That is, for example, a detection unit 51, an operation unit 52 that operates an alarm stop operation, an output unit 54 that outputs an alarm from a speaker 53, a control unit 55 configured by a microcomputer, and a power source that supplies power to each unit It has the structure which has the part 56 and the memory | storage part 57 (for example, refer patent document 1). For example, when the detection unit 51 detects a value larger than a predetermined threshold, the output unit 54 is operated to issue an alarm.

JP 2011-95831 A

  As described above, the conventional alarm device also includes the control unit 55 and the storage unit 57. Therefore, it is possible to store intermediate data such as the history of monitoring data in the monitoring area and the usage time of the power supply battery. However, even if such data is accumulated, such data cannot be tracked unless the alarm is defective and returned. In addition, depending on the installation environment of the alarm device, it may become a storage place for dust and insects, and even if such a product is put in a bag or the like and collected, it is discouraged to take it out of the bag for investigation. Also, depending on the installation environment, the alarm device may fail due to oil stains or insects, and the power may not be turned on. On the other hand, there is a problem that the user cannot know whether the alarm device is operating normally or wants to know information such as how long it will be in the future. is there.

  In addition, when the alarm device is in an alarm state and the person in charge of the gas company or security company is urgently dispatched, for example, if the alarm state of the alarm device is canceled by the user, the alarm can be generated for whatever reason. There is also a problem that it takes time to figure out the cause, and eventually the cause is unknown. In this case, there is a method of displaying the cause of the alarm by LED display (for example, distinguishing by the number of times of lighting), but there is a problem that the confirmation method is complicated and difficult to understand.

  In addition, in order to read various kinds of information from the alarm device collected at the factory, it is necessary to bring the alarm device collected by the worker to the barcode reader, for example, and the barcode reader is placed in the blind spot. When there is a problem, there is a problem that work is required.

  In such a case, if it is possible to know information such as changes in sensor detection values over time using a simple method, it will be necessary for the alarm related companies involved in manufacturing, sales, and maintenance of alarms to use future alarms. It helps to develop improved products to improve performance, and contributes to increasing the utility value of alarm devices for users who are general consumers.

The present invention has been made in view of such a situation, and information on the alarm device (at least one of the alarm device monitoring data and the device data) is requested by the acquirer even when the alarm device is turned off. It is an object of the present invention to provide an alarm device and an alarm device system that can be easily acquired by a portable information terminal in accordance with the above.

Another object of the present invention is to provide an alarm device and an alarm system that can acquire various data when the power source of the alarm device is on.

The alarm device of the present invention is an alarm device having a short-range communication device and capable of exchanging information with an external portable information terminal, which monitors a physical phenomenon in a monitoring area and outputs monitoring data And a storage unit that stores at least one of monitoring data of the sensor unit and device data of the alarm device, and the short-range communication device and the storage unit operate by radio waves from a portable information terminal The information stored in the storage unit can be transmitted to the portable information terminal by communication from the portable information terminal even when the alarm is powered off.

  Here, the short-range communication device is meant to include a device that can communicate at a distance of several meters from a device that can communicate at a few centimeters, such as NFC (Near Field Communication).

Alarm of the present invention may be configured so as to transmit before Symbol monitoring data and / or the device data to the portable information terminal.

  Here, the “apparatus data” means auxiliary information of the alarm device including operation information of the device (for example, alarm device usage time, battery life status, alarm occurrence frequency, etc.).

Monitoring data and equipment data stored in the storage unit includes data defined in accordance with the pre-information acquirer, by mobile information terminal is close to the alarm device, the portable information terminal to be close Based on the identification information transmitted according to the information acquirer from the monitoring data and the device data automatically stored in the storage unit, the monitoring data determined according to the information acquirer and / or or the instrument data, it is preferable that has been configured to transmit to the portable information terminal to be close.

  Here, the proximity means that the distance between the portable terminal and the alarm device is close enough to allow wireless communication. Therefore, if the communication system can transmit and receive even if it is about 10 m away, for example, it is close to within that range, and when the communication distance is only about 10 cm as in NFC (Near Field Communication), It means a distance of about 10 cm.

The alarm device according to the present invention further includes notification means for notifying at least one of the predetermined change of the monitoring data and the abnormality of the device data in the monitoring area, and when the notification is made by the notification means, by being close to the alarm, by has been configured to transmit the information corresponding to different information acquirer and the time of non-broadcast, for example, increase and gas concentration in the monitoring region, failure of equipment Even if notified, an appropriate processing method is shown, which is preferable because the user can cope without panicking.

The physical phenomenon monitored by the sensor unit in the monitoring area is at least one of gas concentration, temperature, and smoke concentration, and the measured value of the monitoring data is periodically stored in the storage unit, and the portable information terminal The monitoring data provided to the system includes the measurement values obtained on a regular basis.For example, even if the alarm user has not issued any alarm, the alarm data Even if it is operating or has not reached the alarm value, it is preferable because, for example, the CO concentration tends to increase and it can be known that ventilation is preferable. Further, since the device data is transmitted to the portable information terminal in addition to the monitoring data, for example, when the alarm device is driven by the battery, how much the battery life is remaining. Also, since it has been used for many years, it is preferable to know that the time for replacement is approaching. Further, the power used in the storage unit is configured to be switched between the power of the power source of the alarm device and the power induced by the radio wave from the portable information terminal according to the radio wave. Also good.

The alarm system of the present invention is an alarm system comprising any one of the above-mentioned alarm devices and a portable information terminal capable of communicating with the alarm device and capable of acquiring information on the alarm device, Even when the power of the alarm device is off, the information in the alarm device can be acquired by the mobile information terminal by communication from the mobile information terminal. In addition, the portable information terminal has a program that always transmits the identification information of the information acquirer according to the information acquirer who uses the portable information terminal to the alarm device, the program is activated, and Monitoring data corresponding to the information acquirer out of monitoring data and device data automatically stored in the storage unit based on the identification information when the portable information terminal is brought close to the alarm device And / or device data may be acquired by the portable information terminal.

  According to the present invention, since the short-range communication device is mounted on the alarm device and various information of the alarm device can be easily acquired with the portable information terminal, the current state (operation status) of the alarm device. And performance changes can be easily obtained. As a result, alarm related companies can easily know the changes in equipment performance, and can use it for subsequent product improvement, or can easily grasp the cause of an abnormality. Or In addition, the user can easily check whether the alarm is operating normally, or can easily know detailed data on whether or not there is a gas leak, even if it does not issue an alarm. This greatly improves the management and usage value of the alarm.

  Furthermore, the short-range communication device has a structure that operates with a radio wave from a portable information terminal with no power source (no connection to an internal power source or an external power source) such as NFC, and has its own storage device. In this case, even if the alarm device is turned off, the information stored in the alarm device can be taken out and recognized. Therefore, for example, alarm device manufacturers such as alarm device manufacturers, sales companies, and management and maintenance companies can estimate changes in sensor sensitivity, sensor life, etc. Basic data for improvement can be obtained very easily. That is, conventionally, if it is a return, the relationship between use time and sensitivity can be known, but the probability of return is very small, and systematic data cannot be acquired. Also, in the case of returned goods, it is often installed in the corner of the kitchen, for example, and it is very dirty, and in some cases pest eggs and larvae are attached and it is very difficult to handle, According to the present invention, even when checking returned goods, it is not necessary to turn on the power of the alarm device, and the previous data can be acquired wirelessly without contact. In addition, since data can be easily acquired wirelessly, for example, when an alarm-related business operator performs periodic inspections, data at that time can also be easily acquired wirelessly. The transition of the data can be obtained. As a result, it can greatly contribute to improving the characteristics of alarm devices and developing new products.

  Furthermore, the user installing the alarm device, for example, installs a data acquisition program in a mobile terminal such as a mobile phone, and simply moves the mobile terminal close to the alarm device. And device data can be obtained very easily. As a result, for example, the user can know how much the current CO concentration is while the alarm is not sounding by simply holding the mobile phone over the alarm, or no alarm is sounding at all. You can know if the alarm is operating normally. Furthermore, the elapsed time since the installation of the alarm device such as how much the battery of the alarm device is valid can be known from the device data, and the life can be easily known. In addition, if the contact information of emergency contact information (telephone number, e-mail address, etc.) of alarm-related business operators is stored, the contact information can be easily found and smooth response in an emergency etc. Can be done.

It is a block diagram which shows the structural example of one Embodiment of the alarm device system of this invention. It is a block diagram which shows the structural example of the alarm device of other embodiment of the alarm device system of this invention. FIG. 3 is a block diagram for explaining an embodiment of power switching of the EEPROM of FIG. 2. It is a flowchart explaining operation | movement of the alarm device system shown by FIGS. It is a flowchart explaining operation | movement of the alarm device system shown by FIGS. It is a figure explaining the structure of the conventional alarm device.

  Next, the alarm device system of the present invention will be described with reference to FIGS. The alarm system of the present invention can communicate with the alarm device 1 including the short-range communication device 15 and the alarm device 1 as shown in the schematic block diagram of the embodiment in FIG. The short-range communication device 15 can be operated with electric power other than the power source 13, for example, a configuration that can be operated with radio waves from the portable information terminal 2, and an alarm. Even when the power supply 13 of the alarm device 1 is turned off, information in the alarm device 1 can be acquired by the portable information terminal 2 by communication from the portable information terminal 2. The alarm device 1 can further include a power source 13 and a microcomputer 12, and the portable information terminal 2 can include a communication control unit 21 and an antenna 22.

  The alarm device 1 is characterized in that a short-range communication device 15 is mounted on a normal alarm device including a sensor for gas detection and smoke detection and a microcomputer 12 having a memory and a control unit. This short-range communication device 15 is not a communication device that is attached to a conventional electronic device that notifies a gas company wirelessly, for example, when an abnormality occurs in a gas alarm device, but is alerted by a portable information terminal at a short distance. It refers to a communication device that can communicate within a few centimeters to 10 meters from which various data in the vessel can be acquired. For example, it means a communication device using a communication standard such as NFC, Bluetooth (registered trademark), Wi-Fi (registered trademark), or RFID (registered trademark).

  If this near field communication device is NFC, for example, even if it does not have a built-in power supply, it is activated by the portable information terminal 2 from various data that is activated by radio waves from the portable information terminal 2 and stored in the internal memory. Since the designated data can be transmitted, even if the power source 13 of the alarm device 1 is turned off, the power source 13 of the alarm device 1 is broken, or the alarm device 1 is not operating due to the battery running out. It is preferable because the information of the alarm device 1 can be easily obtained.

  Next, a specific configuration example when NFC is used as the short-range communication device 15 in a normal alarm device will be described in detail with reference to FIGS. In this embodiment, the short-range communication device 15 is also simply referred to as an NFC tag 15.

As shown in FIG. 2, the alarm device 1 further includes a sensor unit 11 that monitors a physical phenomenon in the monitoring area and outputs monitoring data (detection data for detecting a change in the external environment). Includes a control unit 121 and a memory 122. Moreover, short-range communication device 15 (which may also operate by the electromotive force generated by the electric wave received by the example a loop antenna (power supply 153)) triggered by radio waves from mobile information terminal 2 as a storage unit (EEPROM) has a 152, at least one of monitoring data and alarm devices 1 device data of the sensor unit 11 is Ru stored in the EEPROM 152. As a result, the monitoring data and / or the device data can be acquired by the portable information terminal 2 even when the power supply 13 of the alarm device 1 is off.

  This alarm device 1 is illustrated with a sensor unit 11 similar to a normal alarm device 1, a microcomputer 12 that controls the sensor unit 11 to determine whether the data from the sensor unit 11 is a normal value or an abnormal value. Although not provided, a buzzer and a lamp are provided for notification based on data from the sensor unit 11. In addition to this, the alarm device 1 of the present invention is provided with a wireless communication tag such as an NFC tag 15.

The sensor unit 11 of the alarm device 1 monitors and monitors physical phenomena in the monitoring area, such as a sensor that detects carbon monoxide (CO) gas, methane gas (CH ₄ ), a temperature sensor including a thermistor, or a smoke sensor. Can be used, and one or more types of sensors may be provided. Then, detection data from the sensor in the monitoring area is sent to the microcomputer 12, and the state of the monitoring area is determined based on the data detected by the sensor unit 11.

  The microcomputer 12 of the alarm device 1 has a control unit 121, a memory 122, and the like. And while controlling operation | movement of the sensor part 11, for example, the detection data sent from the sensor part 11 are preserve | saved at the memory 122 etc., and the detection data are compared with the threshold value which is a predetermined reference value. When the detected data exceeds the threshold value, a notification is given by a buzzer or a lamp (not shown). This series of operations is the same as that of a conventional alarm device, and a configuration of a conventionally known alarm device can be used. Further, in the present invention, not only the detection data from the sensor unit 11 is recorded, but also the installation date of the alarm device, the elapsed time from the installation, the relationship between the elapsed time and various data of the sensor unit 11, and the predetermined threshold values. The management data of the alarm device itself, such as the number of times exceeded and the remaining capacity of the battery when the power source 13 is a battery, is also stored in the memory 122 as device data. The microcomputer 12 may be a memory IC that is commercially available.

  In the present invention, as the management data by the microcomputer 12, for example, data desired by an information acquirer described later, for example, inspection data, process records, various correction values, and the like are recorded. Further, various data that can be requested by such an information acquirer is not only stored in the memory 122 in the microcomputer 12 but also stored in an EEPROM 152 provided in the NFC tag 15 described later. However, data that normally does not require reading is also stored in the memory 122. As will be described later, the data stored in the memory 122 can be read directly from the memory 122 even when it is suddenly needed. As described above, data is also stored in the EEPROM 152 of the NFC tag 15, so that data can be directly acquired from the external portable information terminal 2 even when the power supply 13 of the alarm device 1 is turned off. Therefore, the EEPROM 152 of the NFC tag 15 can also be operated by the power source 13 that drives the sensor unit 11 and the microcomputer 12, and the NFC tag 15 side power source 153 (which will be described later is not a battery or the like but is sent from the portable information terminal 2). The electric power induced by the incoming radio wave is also configured to operate. The proper use of the power source is controlled by the alarm-side communication control unit 151 provided in the NFC tag 15.

  The data stored in the memory 122 and the data stored in the EEPROM 152 may be exactly the same data, or there may be data stored in only one of them.

  Also, the data storage format is changed according to the acquirer. For example, the data for the user is stored in the memory 122 and the data stored in the EEPROM 152 are exactly the same data, and the data for the gas company is stored in the memory 122. You may memorize | store so that the data memorize | stored and the data memorize | stored in EEPROM152 may become different data.

  The data stored in the memory 122 and the EEPROM 152 may be changed depending on the use state (for example, the frequency with which each data is acquired). That is, even if the data is initially stored only in the memory 122, it may be stored in the EEEPOM 152 as long as the data is frequently acquired. For example, it may be stored only in the memory 122.

  A power supply 13 for operating the sensor unit 11 and the microcomputer 12 is provided in the alarm device 1. The power source 13 can be rectified using a commercial AC power source. A battery can also be used. If a commercial AC power supply is used, there is almost no concern about the power supply unless a power failure occurs. However, if a battery is used, the alarm device itself will not operate when its life is lost, so its management becomes necessary. In the present invention, the life of the battery can be easily managed by obtaining the usage time or remaining capacity.

  The alarm device 1 of the present invention is characterized in that not only the sensor unit 11 and the microcomputer 12 that manages them but also a tag for wireless communication such as an NFC tag 15 is provided. The NFC tag 15 includes an alarm device side communication control unit 151, an EEPROM 152 that stores the monitoring data and device data described above, a power source 153 for driving the alarm device side communication control unit 151 and the EEPROM 152, and an antenna 154. ing.

  The communication control unit 151 controls communication with the portable information terminal 2 to be described later. For example, based on the identification information (identification code) transmitted from the portable information terminal 2, what information is acquired by the information acquirer. It is determined whether or not it is requested, and control is performed so that only the data requested based on the identification information among the information stored in the EEPROM 152 is transmitted to the portable information terminal 2. This information processing can also be performed by a commercially available IC, like the microcomputer 12 of the alarm device 1.

  The identification code from the portable information terminal 2 can be subdivided into various classifications. For example, the alarm-related business is a large classification a, a1 for a designer, a2 for a gas company, a3 for a management maintenance company, etc., and a large classification b for a user, a b1 for a user 1, a user It can be subdivided into b2 for 2 and the like. If the data to be transmitted is determined according to each identification code, necessary information can be immediately transmitted from the EEPROM 152 to the information acquirer according to the identification code. Therefore, the data stored in the EEPROM 152 is read from the EEPROM 152 even when the power source 13 of the alarm device 1 is turned off. However, as will be described later, if the power supply 13 of the alarm device 1 is turned on, the information stored in the memory 122 of the alarm device 1 can be read without being stored in the EEPROM 152. In addition, new acquisition data can be requested from the portable information terminal 2. That is, an instruction is sent directly from the alarm device side communication control unit 151 to the microcomputer 121, and even the data that is not determined in advance can meet the request from the portable information terminal 2 side.

  Further, if the power supply 13 on the alarm device 1 side is in an on state, the communication is not limited to communication with no power source such as the NFC tag 15 (when there is no original power source such as a battery or a commercial AC power source). Wireless communication that can perform a large amount of information communication such as Bluetooth (registered trademark) can also be used. In short, if the power supply 13 of the alarm device 1 is turned on, it is instructed to acquire the items recorded in the memory 122 of the microcomputer 12 specially or specially after the fact (after the alarm device 1 is installed). It is also possible to write information for instructing the microcomputer 12 to acquire correct data. In other words, since the power source 153 of the NFC tag 15 has very little power as will be described later, it is configured so that it can be transmitted and received through the EEPROM 152 with packetized small simple information.

  An EEPROM (Electric Erasable Program Read Only Memory) 152 as a memory of the NFC tag 15 is a memory that can be electrically erased and written, and stores monitoring data and device data over time as described above. can do. Therefore, changes over time and the number of accidents can be revised and stored every moment. However, in this case, since a large amount of power is required, the power supply 13 on the alarm device 1 side may be used. That is, since the sensor unit 11 does not operate unless the power source 13 is operating, the power source 13 is always operating when data of the sensor unit 11 is output, and the EEPROM 152 is operated using the power source 13. It is connected. Such data is packetized using the power supply 13 of the alarm device 1, so that even if the NFC tag 15 does not have a dedicated power supply, the simple power supply 153 can communicate with the portable information terminal 2. You can send and receive. In order to enable data transmission even when the power supply 13 of the alarm device 1 is off, the EEPROM 152 receives a data acquisition signal from the portable information terminal 2 as will be described later. When the electric power induced by the radio wave is used and no such radio wave is transmitted from the portable information terminal 2, the alarm side communication control unit 151 causes the power source 13 of the alarm unit 1 to be used. It is switched by a controlled changeover switch 155 (see FIG. 3).

  The data stored in the EEPROM 152 includes, for example, data useful for an alarm related company that manufactures, sells, and manages the alarm, such as the number of alarms up to that point, the monitoring data at the time of alarm, the remaining warranty time, the past Inspection results are stored. For production personnel, the name of inspection personnel, serial number, date of manufacture, lot number, etc. For emergency dispatch security personnel, the type of alarm, alarm time, gas concentration, number of alarms, replacement deadline Etc. are useful. Further, as data desired to be acquired by the user side installing the alarm device, for example, an actual measurement value of the sensor unit 11 such as a periodic gas concentration, an inspection result, a remaining capacity of the battery when the battery is used as the power source 13, Examples include the remaining warranty period (replacement deadline) of the alarm device 1 and the type of alarm in the event of an emergency. Even when the data detected by the sensor unit 11 does not reach the alarming threshold, if data such as whether gas is actually leaking can be recognized, attention such as ventilation can be taken. Moreover, even if there is no abnormality at all, if it can be confirmed that the alarm is operating, it is possible to have a sense of security.

  The information stored in the EEPROM 152 is not limited to data such as monitoring data and device data as described above. When a predetermined event occurs (for example, a warning buzzer is generated due to a predetermined change in the monitoring area). It is also possible to memorize a manual on how to respond to the alarm or when an alarm device breaks down, and so that the place to contact can be transmitted. For example, if a user or the like suddenly begins to sound an alarm sound, the user may panic and may not know what to do. In such a case, if the portable information terminal 2 described later is held over the alarm device 1 , “Please call ○○” or “Since city gas is leaking, please close the gas main valve, open the window and ventilate” message on the voice or the display of the portable information terminal 2 Can be displayed.

  Further, for example, a message regarding an item to be confirmed can be transmitted as a message for an alarm-related business operator at the time of alarm. That is, since the correspondence varies depending on the user and the related business operator, necessary information can be sent according to the information acquirer.

  The power source 153 of the NFC tag 15 uses, for example, an electromotive force of electromagnetic induction generated by a coil wound around the NFC tag 15 and also used as an antenna 154 like an IC card. For this reason, the alarm-side communication control unit 151 can be activated by radio waves from the portable information terminal 2 without mounting a battery or the like (without power supply) and even when the power supply 13 of the alarm device 1 is turned off. The information stored in the EEPROM 152 can be transmitted to the portable information terminal 2. In short, a power source 153 and an antenna 154 are formed by a coil (not shown) formed around the NFC tag 15, and transmission / reception with the portable information terminal 2 is performed.

  The EEPROM 152 of the NFC tag 15 is written with monitoring data and device data even when communication with the portable information terminal 2 is not performed. Therefore, the EEPROM 152 is connected so as to be operable by the power supply 13 of the alarm device 1. Therefore, for example, as shown in FIG. 3, the alarm side communication control unit 151 is provided with a power source switch 155, receives a signal from the portable information terminal 2, and the power source 153 operates, so that the alarm side communication control unit When 151 is activated, the power supply changeover switch 155 is activated to operate with the power supply 153 of the NFC tag 15. For example, when the power supply 153 of the NFC tag 15 is not operated, the power supply switch 155 is automatically connected to the power supply 13 of the alarm device.

  It is also possible to instruct the portable information terminal 2 to change the information stored in the EEPROM. In this case, the content that can be changed by an operator such as a user or a gas-related business operator may be the same, or the content that can be changed may be changed by the operator.

  In the above example, it is assumed that NFC uses an RFID (Radio Frequency Identification) standard. For example, as the power source 153 on the NFC tag 15 side, a power source using an induced electromotive force is used, but other known configurations can also be used. In addition, as described above, the alarm device 1 itself has a power source 13 such as a commercial power source or at least a battery. Therefore, if this power supply 13 is used, more data can be transmitted and received, and the utility value is further improved. For example, a communication means such as Bluetooth (registered trademark) can be used.

  As data that can be acquired by a short-range communication device having a built-in power source such as Bluetooth (including connection means such as an outlet connected to a commercial power source), in addition to data acquired by NFC These processing data can also be acquired, and even if it is not set in advance, necessary data can be requested and acquired later.

  For example, when using communication means such as Bluetooth (registered trademark) instead of NFC, a power supply different from the power supply 13 of the alarm device 1 may be provided for the communication means. By doing in this way, even when the power of the alarm device 1 is OFF, communication can be performed similarly to NFC. In this case, although the current technical level requires a power supply, a large amount of data can be transmitted and received, and not only predetermined data but also a request from the portable information terminal 2 can be used for the alarm device 1. Data stored in the memory 122 and processed data of the data can also be obtained. As described above, the use of Bluetooth (registered trademark) requires a power supply at the present time, but has an advantage that a large amount of data can be acquired. Therefore, it is possible to determine what is appropriate for the short-range communication device 15 depending on the purpose.

  If a wireless terminal capable of transmitting and receiving such a large amount of information is used, various types of data transmission and reception can be performed wirelessly. For example, a mobile phone or the like is not brought close to the alarm device 1, that is, far away. The information of the alarm device 1 can be transmitted also to the portable information terminals 2 of the persons concerned.

As the mobile information terminal 2, various mobile devices such as a normal mobile phone, a smartphone, and a tablet information terminal can be used. However, a program for performing communication with the alarm device side communication control unit 151 needs to be installed in advance as an application. As a result, the terminal side communication control part 21 manufactured so that the signal which specified the data requested | required with respect to the alarm device 1 can be transmitted by radio | wireless is built in the portable information terminal 2. FIG. And if an identification code is set according to the type of data to be acquired, if there is only one identification code for the portable information terminal 2, it is only necessary to activate the terminal-side communication control unit 21, An identification code is sent from the antenna 22, and data and / or information corresponding to the identification code is sent back. When there are two or more types of identification codes, after the terminal-side communication control unit 21 is activated, the portable information terminal 2 simply designates an identification code summarizing desired data and holds the portable information terminal 2 over an alarm device. Thus, the desired data and message can be obtained.

  Therefore, when the user transmits a signal indicating desired data including the identification code from the portable information terminal 2 so as to reach the alarm device 1, the alarm-side communication control unit 151 automatically identifies it. The corresponding data of the monitoring data corresponding to the code and the device data can be transmitted. In short, on the NFC tag 15 side, the data desired by the information acquirer according to the identification code sent from the portable information terminal 2 can be immediately transmitted as a packet. Therefore, even if the alarm device 1 does not have a built-in power supply, desired data can be sent back only by the induced power generated by the radio wave transmitted from the portable information terminal 2.

  Next, a flow for transmitting and receiving data using the alarm device 1 and the portable information terminal 2 will be described with reference to a flowchart shown in FIG.

  First, when an information acquisition signal is sent from the portable information terminal 2 (S1), the power source 153 of the NFC tag 15 operates (S2). As a result, the alarm device side communication control unit 151 is activated (S3), the power switch 155 is activated, and the EEPROM 152 is changed to operate with the power source 153 of the NFC tag 15 (S4).

  Next, the identification code of the transmission signal from the portable information terminal 2 is recognized (S5). That is, for example, information required by an alarm-related company in advance is set as a large classification of identification code a, information requested by a user is set as a large classification of identification code b, and what kind of information is assigned to each identification code. By determining whether to transmit, it is possible to immediately recognize which information should be transmitted by recognizing the identification code. Of course, the information required by the alarm related company can be subdivided, and can be subdivided by identification codes such as a1, a2, a3,. In addition, the information required by the user can be subdivided and classified by b1, b2, b3,.

Next, it is determined whether the recognized identification code is an identification code for obtaining normal preset data or an identification code for requesting special data or information not set in advance (S6). For example, such an identification code can be set as x. If this identification code is x (Y in S6), the process proceeds to A described with reference to FIG. If the identification code is not x in the special case (N in S6), whether a predetermined event has occurred when a signal is received from the portable information terminal 2 (for example, due to a predetermined change in the monitoring area) It is determined whether or not an alarm buzzer has sounded or an alarm device has failed (S7).

  If a predetermined event occurs when a signal is received from the portable information terminal 2 (Y in S7), emergency information corresponding to the identification code is transmitted (S8). That is, when the identification code is the identification code a1, a2,... From the alarm device-related business operator, information corresponding to the action to be taken by the alarm device-related business operator, or the identification code b1 from the user. , B2,..., For example, it is recommended to call by providing the telephone number of an emergency contact, etc., or it is recommended to close the gas main valve and open the window to improve ventilation. That is, information corresponding to the identification code is transmitted (S8).

  If a predetermined event does not occur when a signal is received from the portable information terminal 2 (N in S7), the previously classified information is taken out from the EEPROM 152 as a packet and transmitted ( S9).

  The example shown in FIG. 4 is an example in which the information to be transmitted is determined in advance according to the identification code and only the information previously collected as a packet is transmitted, but the power supply 13 of the alarm device 1 is in the on state. If so, the information stored in the memory 122 of the microcomputer 12 of the alarm device 1 can be read from the outside, although not stored in the EEPROM 152. An example is shown as a flowchart in FIG. That is, in step S6 of the flowchart of FIG. 4 described above, when the recognition of the identification code of the transmission signal is a special identification code x (Y in S6), the flow after proceeding to A is shown in FIG. ing.

  That is, FIG. 5 is a flowchart following the case of Y in step S6 of FIG. 4, and is a flow in the case where the recognized identification code is a special identification code x.

  First, it is confirmed whether the power supply 13 of the alarm device 1 is turned on. If the power supply 13 is not turned on (N in S11), a reply that data acquisition is impossible is sent to the portable information terminal 2 (S12). That is, if there is no response even if an instruction is sent from the alarm side communication control unit 151 of the NFC tag 15 to the control unit 121 of the microcomputer 12, it indicates that the microcomputer 12 is not operating, so the power supply 13 operates. You can recognize that you are not.

  In step S11, in the case of Y, the reception information received by the alarm device side communication control unit 151 is transferred to the control unit 121 of the microcomputer 12 (S13). Subsequent S14 to S18 are operations performed by the control unit 121 of the microcomputer 12.

  First, the control unit 121 decodes the transmitted information (S14). If the request is for the content stored in the memory 122, the memory 122 is requested to output the required data (S15). Then, desired data is received from the memory 122 (S16). If the request from the portable information terminal 2 is data that is not yet stored in the memory 112 such as the latest output of each sensor 111, 112,..., The control unit 121 directly acquires the data. (S17). Then, the data received from the memory 122 and / or the data received directly are transmitted to the communication control unit 152 of the NFC tag 15 (S18).

  The communication control unit 152 transmits the received data to the portable information terminal 2 via the antenna 154 (S19). Thus, even data that has not been negotiated in advance can be acquired in response to a request from the portable information terminal 2 side. Thus, when using the power supply 13 of the alarm device 1, as described above, wireless communication with a larger amount of information such as Bluetooth (registered trademark) should be used in combination or in place of the NFC tag. You can also.

  As described above, the wireless communication tag such as the NFC tag 15 is provided, so that the wireless communication tag can be used widely from the manufacturing stage to the product of the alarm device after it is actually installed. That is, since the wireless communication tag is mounted on the substrate at the manufacturing stage, the data at the manufacturing stage can be written and managed wirelessly, so that fine quality control can be performed. That is, in the past, production control was performed by pasting a QR code (registered trademark) or the like, but when the casing was placed on the substrate, it was necessary to re-paste the QR code (registered trademark) again. However, in the present invention, data can be written and read wirelessly even after the case is put on, so that production management can be performed very easily, and reliability is greatly improved in terms of quality control. Can be made. Furthermore, it becomes easy to correct or change a set value such as temperature compensation.

  In addition, regarding quality control after it has become a product, past data can be read without contact, so quality can be managed with the alarm installed, and product management can be performed very finely. it can. In addition, there is a case where it is very dirty and hesitates to touch it because it was installed in the corner of the room, but even in such a situation, the mobile information terminal does not actually touch the alarm device. The past data can be read out simply by bringing them close to each other, and the cause of the returned goods can be easily investigated. Further, even in the case of a return such that the power supply of the alarm device cannot be turned on, the history of past data can be detected without the power supply, so that the reason why the power supply is not turned on can be easily determined.

  Furthermore, it is a very powerful weapon from the viewpoint of performance improvement and maintenance management of alarm devices, both at the site where alarm devices are installed, for alarm device related businesses, and for the user side. In other words, for alarm-related business operators, from sensor data such as changes in sensor sensitivity and differences in the sensitivity of detection targets, and from alarm and failure information acquisition, sensor sensor improvements, installation location improvements, alarms, etc. It is easy to grasp various improvements such as improvement of air permeability in the vessel.

  Further, for the user side, conventionally, only an alarm device is installed, and there is no reaction unless an alarm sound is generated, and it is not known whether it is operating or not. For example, if the alarm device is operating only by holding the mobile phone, for example, whether even a slight gas leak is detected, if the validity period is 5 years from the installation date, It is possible to easily acquire various data such as how many years it is and how many months it is currently valid. Furthermore, by installing the alarm device diagnosis program in a mobile phone or the like, for example, it is possible to easily obtain a diagnosis result that the temperature sensor is normal but the gas sensor is slightly insensitive.

That is, according to the alarm system of the present invention, the monitoring data and device data stored in the EEPROM 152 or the memory 122 of the microcomputer 12 include data predetermined according to the information acquirer, The mobile information terminal 2 always transmits to the alarm device identification information of the information acquirer according to the information acquirer who uses the mobile information terminal 2, for example, an alarm related business operator, a user, or another person. By having the program, the program is started, and the portable information terminal 2 is brought close to the alarm device 1, so that the monitoring data corresponding to the information acquirer automatically and based on the identification information The device data is configured to be acquired. Therefore, whether it is an alarm related company, a user, or another related party, it is necessary for oneself only by holding the portable information terminal 2 to which the identification information is input over the alarm 1. Only information can be acquired.

In this case, not only monitoring data and device data, but also when the predetermined event occurs (for example, when an alarm buzzer sounds due to a predetermined change in the monitoring area, or when the alarm is broken) By storing information (messages such as countermeasures) in the EEPROM 152, the portable information terminal 2 is brought close to the alarm device 1 in the event of an emergency, and processing corresponding to the information acquirer such as an alarm related business operator or user It can be configured that the law is acquired.

  As described above, data acquired by NFC or data acquired by Bluetooth (registered trademark) or the like can be further connected to another communication device via the portable information terminal 2 to share information.

  Further, unlike the above-described embodiment, the control unit 121 and the communication control unit 151 are not provided, but the control unit 121 is configured to include the communication control unit 151, and the power supply 13 is turned off as in the above-described embodiment. In this case, the control unit 121 may be operated by the power source 153 to communicate with the portable information terminal 2.

  Furthermore, the configuration of each part and the flowchart processing shown in the above embodiment are merely examples, and the present invention is not limited to the above-described embodiment, and various other modifications can be made.
