Description

The present invention relates to an alarm and a method of initializing an alarm.

2. Description of the Related Art Conventionally, alarms that monitor the surrounding environment with a temperature sensor or gas sensor and issue an alarm in response to detection of an abnormal condition to notify the user of danger have been used in ordinary homes, commercial facilities, factories, and the like. ing. Such alarms play an important role in ensuring user safety. In recent years, such an alarm device is equipped with an audio signal processing device and an utterance means such as a speaker so that it can emit not only a simple beep sound but also messages conveying various information.

Furthermore, alarm devices with communication functions have become popular so that obtained information can be communicated not only to persons in the vicinity of the alarm device but also to distant parties concerned. In addition to communication with specific communication destinations, alarm devices with such communication functions can transmit information widely, and obtain a large amount of information from the outside and use it to communicate with users around the alarm device. Some are connectable to network lines such as the Internet for added convenience. For example, Patent Literature 1 discloses an alarm device that includes a speaker that issues an alarm message and a LAN port that enables connection to the Internet.

Japanese Patent Application Laid-Open No. 2004-326360

In the alarm device of Patent Document 1, various sensors such as the speaker, the LAN port, and a CO sensor that monitors the surrounding environment and has an alarm function are connected to one signal processing circuit. This single signal processing circuit controls not only the alarm function, which is the main function of the alarm device, but also the communication function. However, in the case of such a configuration, since one signal processing circuit controls both the notification function and the communication function, it may interfere with the main function of the alarm function. For example, the alarm function may be affected by repeated version upgrades of communication protocols to introduce new control methods and improve security levels. In other words, it is conceivable that the alarm function may stop functioning during the update of the software related to the communication function required for such a version upgrade, or that the entire signal processing circuit may become inoperable due to a defect in the update. .

As a means of reducing such risks, it is conceivable to provide a main processing unit that controls the alarm function and a sub-processing unit that controls secondary functions such as communication functions independently of each other. However, if the processor is individually provided for each function and operated in this manner, communication with an external device, for example, may affect the alarm function, which is the main function, depending on the content of the communication. For example, if audio information is sent from an external device and the information is emitted by a speaker shared with the alarm function, the audio alarm may be disturbed by the audio emitted under the control of the sub-processor. .

It is also possible to have the main processing unit control the operation of the sub-processing unit so that the alarm is not disturbed, and limit the utterance by the sub-processing unit when the alarm is issued. However, it is conceivable that the sub-processor, which should operate under the control of the main processor, cannot operate under the control of the main processor. For example, if the alarm device is connected to an external device for communication as described above, the communication may change the internal state of the sub-processing unit that controls communication, such as the contents of the internal memory. be. Also, as described above, the software in the sub-processing device that controls communication may be updated via communication. There is no problem if the internal state of the sub-processing unit is changed and the software is updated appropriately, but if the state is changed to a state that may interfere with the control by the main processing unit, or if the update data contains bugs, there is no problem. It is also conceivable to stay In such a case, as described above, a situation may arise in which the control of the main processor does not extend to the sub-processor. As a result, the alarm may not be issued in the environment intended by the user, or a software bug may cause the alarm function to be fundamentally obstructed and completely disabled.

In such cases, even though the user can sense that the alarm is not working as intended or at all, the lack of remedial action means that the failure condition continues for a long time until repair or replacement by the vendor. It can also happen. Such a situation threatens the safety of users and the like, and is not preferable for the alarm device that plays a role of ensuring the safety of users and the like.

The present invention has been made in view of the above problems, and even if a part of the alarm device fails to function due to a change in the internal state, it can be restored to a normal functioning state under the will of the user or the like. It is an object of the present invention to provide an alarm that obtains and a method of initializing the alarm.

The alarm device of the present invention includes a detection unit capable of detecting at least one of fire or gas, a first processing unit that controls an alarm function that issues an alarm based on the detection result of the detection unit, and at least the alarm A second processing unit that controls a predetermined function other than the function, and a reception unit that receives a manual operation. an alarm configured to perform a deactivation action;

The alarm device may be configured to perform an operation other than the predetermined initialization operation when the receiving unit receives a manual operation other than the predetermined manual operation.

Software built in the second processing unit may be initialized by the predetermined initialization operation.

The alarm device may further include storage means for storing initialization data of the software, and the software may be rewritten using the initialization data in the predetermined initialization operation.

In the predetermined initialization operation, the internal state of the components constituting the second processing unit, which has been changed after the alarm has started to operate, is returned to the state at a specific point in time before the change. good too.

The predetermined manual operation includes a first operation and a second operation, which are operations in different modes, and is incorporated in the second processing unit by the predetermined initialization operation by executing the first operation. Software may be initialized, and the internal state of the part may be returned to the state at the specific point in time by the predetermined initialization operation by executing the second operation.

<Reception Department>
The reception unit 70 receives a manual operation of the alarm device 100 by, for example, a user or an administrator of the alarm device 100 (hereinafter, a person who manually operates the reception unit 70 is collectively referred to as an “operator”). The receiving unit 70 receives manual operations performed by the operator to instruct the alarm device 100 to perform various predetermined operations. A manual instruction to the reception unit 70 is converted into an electric signal or the like and transmitted to the first processing device 10 and/or the second processing device 20 . Actions dictated by that manual operation are performed by either or both processors. The alarm device 100 of FIG. 1 has one receiving section 70 . However, the alarm device 100 of the present embodiment may include any number of one or more reception units 70 that can be manually operated independently of each other.

<Initialization of the second processing unit>
As described above, the alarm device 100 of the present embodiment includes the receiving section 70 that receives the manual operation of the operator. The alarm device 100 of the present embodiment is configured to execute a predetermined initialization operation of the second processing section 2 when a predetermined manual operation is performed on the reception section 70 . In this specification, "configured" so that the alarm device 100, the first processing device 10, or the second processing device 20 performs (or does not perform) a specific operation or process means that the alarm device 100, the first processing unit 10, and/or the second processing unit 20 to perform (or not to perform) their particular operations or processes are included in the program describing the operations and processes of each processing unit. including being

In this embodiment, when a predetermined manual operation is performed on the reception unit 70 in this manner, a predetermined initialization operation of the second processing unit 2 is executed. The “initialization” of the second processing unit 2 is to set some or all of the constituent elements of the second processing unit 2 to the state when the alarm device 100 is shipped from the manufacturing factory, the state when the alarm device 100 starts operating, Alternatively, it may be to restore the state before the alarm device 100 and the network N were connected. Alternatively, the “initialization” of the second processing unit 2 is to set some or all of the constituent elements of the second processing unit 2 to an appropriate state after initialization of the second processing unit 2 ( For example, a specific state stored in the storage means 20a) or in the storage means 30 may be set.

That is, the second processing unit 2 transitions to a state from the factory shipment of the alarm device 100 to the start of operation, or to a state prepared in advance as an appropriate state, by initialization by a predetermined manual operation. For example, if the software SW built in the second processing unit 20 is updated (that is, changed) with update data containing bugs and is in a state where it cannot operate normally, the second processing unit 20 is initialized. 20 is restored to its pre-update state (pre-change state). Even if the warning function of the first processing unit 1 is impeded due to improper operation of the second processing unit 20, the impediment is resolved. Since the alarm device 100 of the present embodiment is configured such that the second processing unit 2 can be initialized by a predetermined manual operation by the operator, the alarm device 100 is restored to a state in which the alarm function can be properly exhibited. can do.

To elaborate on the effects of the alarm device of this embodiment, in the alarm device 100, as shown in FIG. It is Therefore, when the software SW of the second processing unit 20 is updated in accordance with, for example, a version upgrade of a communication protocol, it is unlikely that the alarm function will stop due to the direct influence of the update failure. Also, the first processing unit 10 is relieved of the burden of controlling functions other than the alarm function.

On the other hand, if the second processing unit 20 operates independently, the sound emitted by the second processing unit 2 to the output unit 40 based on communication with the external device E, for example, may interfere with the sound of an alarm or the like. In a configuration where the second processing device 20 is controlled by the first processing device 10, such a situation can be easily avoided. It is also possible to deviate from In addition, in the second processing device 20 that can be connected to the external network N, such separation from the control of the first processing device 10 may result in reception of unfavorable information from any external device E connected to the network N. sometimes brought about. Furthermore, it is conceivable that a particular input port of the second processing unit 20 provided to accept control of the first processing unit 10 fails.

In such a state that the second processing device 20 is separated from the control of the first processing device 10, the alarm function is activated by the processing on the second processing device 20 side even though the first processing device 10 is normal. may not function as intended. For example, as described above, an audio warning may be drowned out by communication-based audio and may not reach the user or may be difficult to hear. That is, even though the first processing device 10 and the second processing device 20 are provided separately, the alarm function is appropriately activated by the change in the state of the second processing device 20 after the alarm device 100 starts operating. It may fall into a state of non-performance. In particular, when the second processing device 20 reaches a state where it cannot accept the control of the first processing device 10, the first processing device 10 cannot restore the second processing device 20 to its normal state. In the first place, the first processing device 10 cannot notice the abnormality of the second processing device 20 . Therefore, it is difficult for the alarm device 100 itself to recover to a state in which the alarm function can be properly exhibited. Therefore, it is likely that the alarm device needs to be replaced or repaired by a contractor, and the user or the like is likely to be placed in a substantially unmonitored environment until the replacement or repair is completed.

In this way, even when the alarm device 100 itself is unaware of the malfunction of the alarm function and cannot autonomously restore the normal state, the user or the like can notice the malfunction of the alarm function by the sound or display of the output unit 40. Sometimes I get However, if the user who notices the problem does not have a means to solve the problem, it will still be difficult to quickly solve the problem of the warning function.

Therefore, the alarm device 100 of the present embodiment is provided with the reception unit 70 that receives a manual operation, and when a predetermined manual operation is performed on the reception unit 70, the second processing unit 2 including the second processing unit 20 performs a predetermined operation. is configured to perform the initialization operations of The operator who notices that the alarm device 100 is not operating normally returns the second processing unit 2 to, for example, the state before the operation of the alarm device 100 is started by performing a predetermined manual operation on the reception unit 70. or to a state prepared in advance as an appropriate state. If the second processing device 20 was under the control of the first processing device 10 when the alarm device 100 started operating, the alarm device 100 is returned to a state in which the control of the first processing device 10 over the second processing device 20 is valid. can be done. For example, in the case where the first processing device 10 controls the second processing device 20 so as not to emit sound when an alarm is issued, the second processing device 20 does not cause the output unit 40 to emit sound when an alarm is issued.

Therefore, an audible warning can be delivered to the user in an unobstructed and easily audible state. In other words, even if the alarm function is hindered by the operation of the second processing unit 2, the second processing unit 2 returns to a normal state autonomously or under the control of the first processing unit 1. Even if you are unable to do so, you can overcome the obstacles. As described above, in the alarm device of the present embodiment, the second processing unit 2 can be initialized by a predetermined manual operation. Even if it falls into an accident, the alarm device can be restored to a state in which it can function normally under the will of an operator such as a user.

<Manual operation>
FIG. 2 schematically shows manual operations to the alarm device 100 installed in the house as some examples of manual operations accepted by the accepting unit 70 . As an example, the accepting unit 70 accepts an operator's physical operation M such as touching the accepting unit 70, as shown in FIG. In that case, the reception unit 70 is provided, for example, in the housing 60 or the like in such a manner that physical operations such as contact, push-in or pull-out, or shift by the operator are possible. Examples of components of the accepting unit 70 that accepts physical manual operations in this way include various switches that are provided in the alarm device 100 so as to be visible and contactable from the outside. When the reception unit 70 is composed of a switch, the part to be operated by the switch may be connected to an operation button exposed from the housing 60 . Examples of switches used as the receiving unit 70 include push button switches and toggle switches, but are not limited to these. For example, the reception unit 70 may be an input device such as a touch panel or a keypad.

The push button switch used as the reception unit 70 may preferably be a tactile switch that is pushed only during operation and automatically resets after the operation is completed. If the reception unit 70 is configured with a tactile switch, the alarm device 100 may be instructed to perform different operations depending on the length of time the button is pushed or the number of times the button is pushed repeatedly within a certain period of time. Further, the pressing over a arbitrarily selected specific period of time may be a "predetermined manual operation" for instructing the second processing unit 2 to perform the initialization operation, or the arbitrarily selected specific period of time. A certain number of repeated presses may be a "predetermined manual operation."

In addition, the reception unit 70 receives a manual operation through a medium such as an electromagnetic wave such as light, a sound wave, or an electric wave instead of a direct physical operation of the operator to the alarm device 100 such as touching the reception unit 70 directly. good too. That is, the reception unit 70 receives light, sound, radio waves, or the like emitted by a manual operation performed on a device separate from the alarm device 100 to give an instruction to the alarm device 100. It may be accepted as an operation. In this case, the reception unit 70 is a photoelectric conversion element such as a photodiode that converts light into an electric signal, a sound sensing element such as a microphone that converts sound into an electric signal, or a reception element having an antenna that receives radio waves. may be configured. The reception unit 70 that receives radio waves may be replaced by the communication unit 21 (see FIG. 1).

When the accepting unit 70 accepts a manual operation mediated by radio waves, light, or the like, the operator uses a dedicated remote controller, such as a remote control attached to the alarm device 100, connected to the alarm device 100 by short-range communication, for example, as the manual operation. Direct manual operations can be performed on the terminal. In addition, as a manual operation for the reception unit 70, the operator performs direct manual operation on various general-purpose portable terminals such as smartphones, which are made into dedicated terminals by application programs and connected to the alarm device 100 by short-range communication. (Hereinafter, dedicated terminals and dedicated general-purpose portable terminals are collectively referred to as "dedicated terminals", and are shown with the symbol "Pn" in FIG. 2). The short-range communication used by the dedicated terminals Pn may be, for example, short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark), or optical wireless communication such as IrDA, but is not limited to these. . Furthermore, the operator manually operates the reception unit 70 by using an external device E connected to the communication unit 21 of the alarm device 100 via wired communication or wireless communication via the network N or the base station B of the communication carrier, It is also possible to perform a direct manual operation on a remote terminal Pr such as a smart phone.

In this way, the “manual operation” on the reception unit 70 may be performed on a device separate from the alarm device 100 . On the other hand, the generation of an instruction that causes the alarm 100 to perform a particular action, either internally to the alarm 100 or externally to the alarm 100 and sent to the alarm 100 without operator intervention in its occurrence, is a "manual operation." not included in For example, execution of a command that instructs the alarm device 100 to perform a specific operation, which is written in the built-in program of the alarm device 100 or the control program of the external device E, is not included in the “manual operation”.

<Prescribed manual operation>
The “predetermined manual operation” that causes the second processing unit 2 to perform the initialization operation may be an operation of a specific mode arbitrarily selected from the above-described “manual operations” received by the receiving unit 70. As an example, when the reception unit 70 is the tactile switch described above, pressing the tactile switch, which is the reception unit 70, for five seconds or more, for example, may be the "predetermined manual operation". Pushing may be a "predetermined manual operation". As another example, when the receiving unit 70 is a toggle switch, the "predetermined manual operation" may be placing the toggle switch in one of the two states for a specific time or longer. The "predetermined manual operation" may be to switch the toggle switch in a specified number of times or more within a specified time.

Further, when the reception unit 70 is a touch panel, the “predetermined manual operation” may be touching a specific icon displayed on the touch panel. It is also possible to draw with Further, when the reception unit 70 is a keypad, the "predetermined manual operation" may be typing in a predetermined specific pattern. Furthermore, when the predetermined manual operation is performed by direct manual operation of the dedicated terminals Pn or the external device E connected to the alarm device 100 via the Internet or the like, the "predetermined manual operation" is , dedicated terminals Pn or external equipment E to send a preselected specific command, specific message or specific protocol data unit to the alarm 100 . When the accepting unit 70 accepts such a “predetermined manual operation”, the second processing unit 2 performs initialization.

The alarm device 100 of the present embodiment performs not only the "predetermined manual operation" on the reception unit 70, but also the "predetermined manual operation" and the operation other than the operation on the reception unit 70. may be configured to perform a predetermined initialization operation. In this case, it may be possible to prevent unintended and erroneous initialization of the second processing unit 2 . For example, the alarm device 100 in the example of FIG. 1 including the power plug 61 performs the second process by performing a “predetermined manual operation” on the reception unit 70 and connecting or disconnecting the power plug 61 and the commercial power supply. It may be configured to execute a predetermined initialization operation of the unit 2 . That is, the initialization of the second processing unit 2 may be performed when the power supply to the alarm device 100 is started or stopped together with the “predetermined manual operation” on the reception unit 70 .

For example, when the power plug 61 is not connected to a plug socket (outlet, not shown) connected to a commercial power source, the tactile switch provided as the reception unit 70 is pushed in, and the power plug 61 is is plugged into an outlet, a predetermined initialization operation of the second processing unit 2 may be performed. Alternatively, the "predetermined manual operation" is performed while the power plug 61 is connected to the plug socket. Although this alone does not initialize the second processing unit 2, the power plug 61 is once disconnected from the outlet while the "predetermined manual operation" is being performed, and the "predetermined manual operation" is stopped. When the connection is reconnected from (or while being continued), a predetermined initialization operation of the second processing unit 2 may be executed.

In this case, the alarm device 100 has an EEPROM or the like that stores the state of the reception unit 70 when the power supply is stopped, that is, the "predetermined manual operation" was being performed when the power plug 61 was disconnected from the outlet. A non-volatile memory is provided. In the alarm device 100 shown in FIG. 1, the state of the reception unit 70 at the time of power supply stop is determined by the storage means 30, the storage means 20a in the second processing device 20, or the first processing device 10 being EEPOM or the like. can be stored in the storage means.

In addition to the "predetermined manual operation" exemplified above, the receiving unit 70 in this embodiment may be configured to receive a manual operation different from the "predetermined manual operation". Then, the alarm device 100 of the present embodiment executes an operation other than the "predetermined initialization operation" of the second processing unit 20 when the reception unit 70 receives a manual operation other than the "predetermined manual operation". may be configured. The alarm device 100 configured in this way can instruct the alarm device 100 to execute two or more types of operations including initialization of the second processing unit 2 simply by including a small number of reception units 70 . can. Operations executed when the receiving unit 70 receives a manual operation other than the "predetermined manual operation" include, for example, self-inspection of the alarm device 100, stopping the alarm being issued, and switching operation modes (for example, normal mode and normal mode). power saving mode), change the volume of the alarm sound, etc., but are not limited to these.

A manual operation other than the "predetermined manual operation" may be any manual operation other than the "predetermined manual operation". For example, when the reception unit 70 is the tactile switch described above, the manual operation other than the "predetermined manual operation" is a pressing time of the tactile switch that is shorter than the pressing time of the "predetermined manual operation" (for example, less than 5 seconds). can be Alternatively, the manual operation other than the "predetermined manual operation" may be a number of presses that is less than the number of times of pressing as the "predetermined manual operation" within a specific time (for example, 5 seconds). Even when the reception unit 70 is a toggle switch, switching between two states of the toggle switch in a manner different from the manner of switching between the two states of the toggle switch as the "predetermined manual operation" is referred to as the "predetermined manual operation." can be a manual operation other than

Further, when the reception unit 70 is a touch panel, the manual operation other than the "predetermined manual operation" may be touching an icon other than the icon displayed as the "predetermined manual operation". Alternatively, if the receiving unit 70 is a keypad, the manual operations other than the "predetermined manual operation" may be drawn with a fingertip or the like. It can be typing in a pattern different from the pattern typed as "operation". Similarly, when a predetermined manual operation is performed by direct manual operation of the dedicated terminals Pn or the external device E described above, a command or message different from the command or message sent as the "predetermined manual operation" is sent. may be a manual operation other than the "predetermined manual operation".

As described above, when the reception unit 70 is also used to instruct the execution of an operation other than the predetermined initialization operation of the second processing unit 2 (for example, to stop an alarm being issued), the "predetermined manual operation" is It is preferable that the operation is complicated or more difficult than the operation for instructing an operation other than the predetermined initialization operation of the second processing unit 2 . Further, unlike the above, if the reception unit 70 is configured to receive only the "predetermined manual operation" that instructs the predetermined initialization operation of the second processing unit 2, the reception unit 70 is difficult for the user to operate in the housing 60. position. For example, when the housing 60 is provided with a plurality of reception units that can be operated by the user, including the reception unit 70, the reception unit 70 that receives only the “predetermined manual operation” is preferably operated more than the other reception units. placed in a difficult position. It may be possible to prevent unintended execution of initialization operations due to user carelessness.

The specific components of the second processing unit 2 that are actually initialized in the "predetermined initialization operation" of the second processing unit 2 are initialized to cause the second processing unit 2 to start operating the alarm device 100. There is no particular limitation as long as it can return to the previous state or transition to a state prepared in advance as an appropriate state. As described above, the second processing section 2 is mainly composed of the second processing device 20 . Therefore, as the "predetermined initialization operation" of the second processing section 2, preferably the second processing device 20 is initialized. In the initialization of the second processing device 20, the internal state of the second processing device 20 is returned to the state before the operation of the alarm device 100 was started, or shifted to a state prepared in advance as an appropriate state.

<Example of Predetermined Initialization Operation of Second Processing Section: Initialization of Software>
As an example, the software SW built in the second processing unit 2 may be initialized by a predetermined initialization operation of the second processing unit 2 executed by a predetermined manual operation on the reception unit 70 . In the example of FIG. 1, the software SW is specifically built in the storage means 20a of the second processing device 20. FIG. As described above, the second processing unit 20 operates according to instructions included in the software SW stored in the storage unit 20a. By restoring the software SW containing instructions to be followed by the second processing unit 20 to, for example, the factory shipment of the alarm device 100 or the state at the start of operation of the alarm device 100, a problem occurs due to a change in state after the start of operation. It may be possible to restore the second processing unit 20 to a normal state.

The software SW written in the memory of the second processing device 20 such as the storage unit 20 a may be firmware for the second processing device 20 . If the software to be initialized is firmware having a function to control the basic control of the internal circuits and devices of the second processing unit 20, the initialization can more reliably prevent the second processing unit 20 from malfunctioning. It can return to normal state from the holding state. When the software SW is initialized, the storage unit 20a is preferably configured with easily rewritable memory such as EEPROM or flash memory.

<Another Example of Predetermined Initialization Operation of Second Processing Section: Reproduction of Internal State (Reset)>
In the alarm device 100 of the present embodiment, in the predetermined initialization operation of the second processing unit 2, in addition to the initialization of the software SW described above, the operation of the second processing unit 2 changed after the operation of the alarm device 100 is started. The internal state of a component, for example the internal state of the second processing unit 20, may be returned to the state at a particular point in time before the change was made. That is, the state of each component in the second processing unit 20, for example, the contents of a specific storage area in the storage means 20a, the state of the input/output port, the address of the instruction to be executed next in the second processing unit 20 is changed or changed at any time after the alarm device 100 starts operating. The states of these constituent elements are returned to the state at a specific point in time before the modification or change in the "predetermined initialization operation" of the second processing unit 2 .

The “specific time point” is, for example, when the alarm device 100 is shipped from the factory, when the alarm device 100 starts operating, when the alarm device 100 is connected to the network N, or when each component of the second processing device 20 may be at any time prior to any of the changes made to the . What state the constituent elements in the second processing unit 20 are returned to in what state is described in the software SW in which the instructions executed by the second processing unit 20 are described, or the storage means 20a or the storage means 30 may be stored.

As an example, in a predetermined initialization operation of the second processing unit 2, the value of the program counter may be set to zero (cleared) or set to a predetermined specific value. In addition, in the predetermined initialization operation of the second processing unit 2, the stored contents of the temporary storage area such as the RAM and various registers provided in the second processing unit 20 are cleared, or the predetermined information in the temporary storage area is lost. It may be stored. Furthermore, in the predetermined initialization operation of the second processing unit 2, the timer and input/output ports provided in the second processing unit 20 are set to predetermined states, and the interrupt processing of all the second processing unit 20 is prohibited. You may move to By causing the second processing device 20 to clear the program counter and clear the temporary storage area as described above, the internal state of the second processing device 20 can be changed or changed after the alarm device 100 starts operating. It may be possible to revert to the state at a particular point in time before the change. As a result, it may be possible to restore the second processing apparatus 20, which has malfunctioned due to a change in state after the start of operation, to a normal state.

The second processing unit 20 can have a function of executing various reset processes such as external reset by setting a specific input terminal (external reset terminal) to a specific level and power-on reset. In a predetermined initialization operation of the second processing unit 2, the state at a specific point in time when each component in the second processing unit 20 is returned is It may be the same as the internal state. That is, in the predetermined initialization operation of the second processing section 2, any one of the various reset processes provided in the second treatment device 20 as described above may be executed.

The alarm device 100 of the present embodiment may be configured to select a process to be performed as a predetermined initialization operation of the second processing section 2 according to a predetermined manual operation mode of the reception section 70 . That is, the “predetermined manual operation” accepted by the accepting unit 70 may include a plurality of types of manual operations that are operations in different modes. Then, a predetermined initialization operation of the second processing unit 2 may be performed according to each of the plurality of types of manual operations.

For example, software SW built in the second processing unit 2 is initialized by a predetermined initialization operation performed in response to execution of a first operation, which is one of a plurality of types of manual operations. Then, a predetermined initialization operation performed in response to execution of a second operation, which is one of a plurality of types of manual operations and is different from the first operation, changes the second processing after the alarm device 100 starts operating. The internal state of device 20 may be reverted to the state at a particular point in time before the change was made. In this way, when the initialization operation of the second processing unit 2 is executed in response to each of a plurality of types of predetermined manual operations, for example, appropriate second processing according to the malfunction state that the alarm device 100 is actually exposed to can be performed. The initialization operation of the part 2 can be selected by the operator.

As an example, if the "predetermined manual operation" is to press the tactile switch, which is the receiving unit 70, for 5 seconds or longer as described above, for example, pressing for 5 seconds to 10 seconds is the first operation, and pressing for 10 seconds or longer is the first operation. may be the second operation. Further, when the tactile switch that is the reception unit 70 is pushed five times or more within five seconds is the "predetermined manual operation", the first operation is the pushing five times or more within three seconds. Five or more presses within seconds can be the second operation. Further, when the reception unit 70 is a touch panel, touching a first icon, which is one of a plurality of icons displayed on the touch panel as a predetermined manual operation, is the first operation, and touching the second icon is the first operation. can be the second operation.

<Example of initialization operation of the second processing unit by manual operation to the reception unit>
With reference to FIG. 3 which shows an extract of the reception unit 70, the second processing device 20, and the storage unit 30, transmission of the execution instruction of the initialization operation from the reception unit 70 to the second processing device 20 and the second processing. A specific example of processing performed as an initialization operation of the device 20 will be described.

In the example shown in FIG. 3 , the reception unit 70 is connected to the input port 200 of the second processing device 20 . The second processing unit 20 is configured to perform a predetermined initialization operation of the second processing unit 20 when the input port 200 is set to a predetermined level (for example, a low level such as GND potential). When receiving unit 70 receives a predetermined manual operation, receiving unit 70 outputs a signal of a predetermined level. Since the input port 200 of the second processing unit 20 is set to a predetermined level, the internal state of the second processing unit 20 that has been changed after the alarm device 100 has started operating is changed as a predetermined initialization operation. Revert to a point in time before the change was made. As described above, in the predetermined initialization operation of the second processing unit 2, when the external reset among the various reset processes provided in the second processing unit 20 is executed, the input port 200 is connected to the second processing unit 20. may be an external reset terminal that is provided in and receives a reset operation execution request from the outside.

Further, in the predetermined initialization operation of the second processing unit 2, when the power-on reset provided in the second processing unit 20 is executed, as an example, as indicated by the two-dot chain line in FIG. The opening/closing state of the switch 10b is controlled by a predetermined manual operation on the portion 70. FIG. The switch 10 b is arranged on the supply line of the power supply voltage VDD to the power supply terminal Vcc of the second processing device 20 . When a predetermined manual operation is performed on the reception unit 70, the switch 10b is once controlled to be in a non-conducting state. Since the supply of power VDD is restarted after being cut off, a power-on reset of the second processing unit 20 is executed. The power-on reset in this case is performed by a software SW so as to restore the changed internal state of the second processing unit 20 to the state at a specific time before the change by a series of processing by executing the power-on reset. programmed in By executing the power-on reset, the changed internal state of the second processing unit 20 is returned to the state at a specific time before the change.

Also, in the example of FIG. 3, the software SW followed by the second processing unit 20 may include an instruction to execute the initialization of the software SW when a predetermined signal is input to the input port 200. . In this case, upon receiving a predetermined manual operation, the receiving unit 70 sends out a predetermined signal such as high level, low level, or transition from one of high level and low level to the other. As a result, the software SW is initialized in the second processing device 20 .

In the example of FIG. 3, the second processing unit 20 incorporates software SW in the first area A1, which is a specific storage area of the storage means 20a. Software SWi prepared as initialization data is stored in the n-th area, which is a specific storage area of the storage means 20a different from the first area A1. The software SWi includes, for example, a control program prepared so that the second processing unit 20 follows the shipment of the alarm device 100 from the manufacturing factory and the start of operation. As an example, the software SWi may be the same software as the software stored in the first area A1 when the alarm device 100 is shipped from the factory or when the operation is started, or may be software separately prepared for initialization. may

When the second processing unit 20 receives a predetermined signal input to the input port 200 and initializes the software SW, the second processing unit 20 changes the memory content of the first area A1 so that the software SWi is executed instead of the software SW. may be rewritten by the software SWi of the n-th area An. As a result, the second processing unit 20 operates according to the instructions written in the software SWi. As an example, the initialization of the second processing device 20 may be performed by the initialization of the software SW in this way.

The initialization of the software SW of the second processing unit 20, which is performed as a predetermined initialization operation of the second processing unit 2, does not have to be performed using the initialization data stored in the second processing unit 20. . For example, in the example of FIG. 3, the software SWi prepared as initialization data is also stored in the storage means 30 provided separately from the second processing device 20 in the alarm device 100 . When the software SW in the second processing unit 20 is initialized as a predetermined initialization operation of the second processing unit 2 by inputting a predetermined signal to the input port 200, the software SW in the second processing unit 20 is stored in the storage unit 30. It may be rewritten using software SWi, which is stored initialization data. In this way, when the software SW is initialized using the initialization data stored in the internal memory of the alarm device 100 such as the storage means 20a and the storage means 30, the initialization data is sent from the outside of the alarm device 100. In some cases, the second processing unit 2 can be restored to its normal state more quickly than when data is supplied.

The software SW built in the second processing device 20 may be initialized using a boot loader that is provided in the second processing device 20 and controlled by the program for booting the second processing device 20 . In this case, the second processing unit 20 is configured to receive a reboot instruction from the outside, and further initializes the software SW if a specific port is in a predetermined state when the reboot instruction is received. configured as When the boot loader is used to initialize the software SW, the second processing device 20 in the example of FIG. When the input port 200 is set to a predetermined reboot instruction level such as low level or high level when the reboot instruction signal is received, the software SW is initialized.

Upon receiving a predetermined manual operation, the receiving unit 70 sends to the input port 200 a predetermined reboot instruction signal that transitions from one of high level and low level to the other reboot instruction level. . After the reboot instruction signal is input, input port 200 is set to the reboot instruction level, which is the level after transition of the reboot instruction signal. On the other hand, a delay circuit 71 is provided between the input port 201 and the receiving section 70 . The delay circuit 71 is composed of, for example, a capacitor and a resistor, and delays the timing of level transition of the reboot instruction signal by a certain time. Therefore, when the reboot instruction signal is input to the input port 201, the input port 200 is already set to the reboot instruction level for executing initialization of the software SW. Therefore, the software SW is initialized in the second processing device 20 . Even if the second processing unit 20 is in a state where the software SW cannot be initialized simply by executing the software SW, it may be possible to initialize the software SW by using a boot loader controlled by the startup program. .

It should be noted that the initialization of the software built in the second processing unit 20, which is executed as the initialization of the second processing unit 2, does not rewrite the storage contents of the storage means 20a, but simply the program executed by the second processing unit 20. may be performed by switching the That is, in the example of FIG. 3, when the receiving unit 70 receives a predetermined manual operation, the second processing device 20 is stored in the n-th area An instead of the software SW stored in the first area A1. It may be configured to operate according to instructions contained in software SWi.

FIG. 4 shows another example of a mode of transmission of the initialization operation execution instruction from the receiving unit 70 to the second processing device 20 . The example in FIG. 4 is different from the example in FIG. 3 in that an identification unit 72 is provided between the reception unit 70 and the second processing unit 20. In FIG. In FIG. 4 (and FIG. 5, which will be referred to later), the same reference numerals as those in FIG. 3 are attached to FIG. will be omitted.

As described above, when the receiving unit 70 also receives manual operations other than the "predetermined manual operation", the identifying unit 72 identifies the "predetermined manual operation" from among the manual operations performed on the receiving unit 70. do. The identification unit 72 is configured by, for example, a timer that counts the elapsed time, a counter that counts the number of operations performed on the reception unit 70, and the like. In this case, for example, as described above, the identification unit 72 determines whether the length of time the tactile switch, which is the reception unit 70, is pressed, the number of times the switch is repeatedly pressed within a specific time period, and the like, satisfy the requirements for a predetermined manual operation. is determined by The identification unit 72 may be configured with a comparison circuit that determines whether or not the signal sent from the reception unit 70 satisfies predetermined manual operation requirements by comparison with a reference signal.

If the requirements for a predetermined manual operation are satisfied, the identification unit 72 identifies that the manual operation being performed on the reception unit 70 is a predetermined manual operation, and the input port of the second processing device 20 200 to a predetermined level, send a predetermined signal, or send a reboot instruction signal to the input ports 200 and 201 . The identification unit 72 may control the open/closed state of the switch 10b according to the identification result. On the other hand, a manual operation other than the predetermined manual operation is transmitted to the input port 202 of the second processing device 20, and the second processing device 20 executes an operation corresponding to the manual operation.

FIG. 5 shows still another example of a mode of transmission of the initialization operation execution instruction from the receiving unit 70 to the second processing device 20 . In the example of FIG. 5, a manual operation performed on the reception unit 70 is transmitted to the first processing device 10, and the first processing device 10 identifies whether or not it is a predetermined manual operation. When the manual operation performed on the reception unit 70 is a predetermined manual operation, the first processing device 10 instructs the second processing device 20 to perform a predetermined initialization operation.

In the example shown in FIG. 5, the first processing unit 10 has an output port 101 for initialization of the second processing unit 20, the output port 101 of which functions in the same manner as in the example of FIG. It is connected to input port 200 of device 20 . That is, the second processing device 20 is configured to perform a predetermined initialization operation of the second processing device 20 when the input port 200 is set to a predetermined level. The first processing device 10 outputs a signal of a predetermined level from the output port 101 to the input port 200 when a predetermined manual operation is performed on the reception unit 70 . Since the input port 200 of the second processing unit 20 is set to a predetermined level, the internal state of the second processing unit 20 that has been changed after the alarm device 100 has started operating is changed as a predetermined initialization operation. Revert to a point in time before the change was made. Further, the first processing device 20 may output an appropriate control signal from the output port 102 to control the open/closed state of the switch 10b in response to a predetermined manual operation on the reception unit 70. FIG. A predetermined initialization operation of the second processing device 20 may be performed using a power-on reset function provided in the second processing device 20 by such control of the open/close state of the switch 10b.

Further, in the example of FIG. 5, if the software SW contains an instruction to instruct the second processing unit 20 to initialize the software SW when a predetermined signal is input to the input port 200, the reception The first processing device 10 may send a predetermined signal to the input port 200 when the unit 70 receives a predetermined manual operation. As a result, the software SW is initialized in the second processing device 20 .

The first processing device 10 may cause the second processing device 20 to initialize the software SW built in the second processing device 20 using a boot loader provided in the second processing device 20 . In this case, as described above with reference to FIG. 3, the second processing device 20 is configured to receive a reboot instruction signal from the outside. In the example of FIG. 5, the second processing device 20 receives the reboot instruction signal at the input port 200, and the input port 201 is set to a predetermined reboot instruction level such as low level or high level when the reboot instruction signal is received. In this case, the software SW is configured to be initialized. The first processing unit 10 outputs a predetermined reboot instruction signal from the output port 101 connected to the input port 200 when executing the initialization of the software SW as the initialization of the second processing unit 2 . The first processing device 10 further sets the output port 103 connected to the input port 201 of the second processing device 20 to the reboot instruction level at the same time as or before sending the reboot instruction signal. As a result, the software SW is initialized in the second processing device 20 .

<Method for initializing the alarm device of the embodiment>
Referring again to FIG. 6 and FIG. 1 as appropriate, a method for initializing an alarm device according to one embodiment of the present invention will be described below using the alarm device 100 illustrated in FIG. 1 as an example. FIG. 6 is a flow chart showing an example of the procedure in the initialization method of the alarm device of this embodiment. In FIG. 6, on the left side of the chain double-dashed line L1, processing executed in each step of the alarm device initialization method of the present embodiment is shown. Further, on the right side of the two-dot chain line L1, processing performed by the second processing unit 2, including processing performed in relation to each step in the method for initializing the alarm device of the present embodiment, is shown. The constituent elements of the alarm device 100 described with reference to FIGS. 1 to 5, and the functions and actions of each constituent element, are initialized by the alarm device initialization method of the present embodiment. Alarms and components thereof may be included as well. Further, the operations and processes performed on the alarm device 100 described with reference to FIGS. 1 to 5 are included as part of the series of procedures in the method for initializing the alarm device of the present embodiment. may

The initialization method of the alarm device of the present embodiment includes, as an example, a detection unit 50, a first processing unit 1, a second processing unit 2, a reception unit 70 for receiving manual operation, A method of initializing an alarm such as the alarm 100 comprising: Here, the detection unit 50 can detect at least either fire or gas. The first processing unit 1 controls an alarm function that issues an alarm based on the detection result of the detection unit 50 . The second processing unit 2 controls at least predetermined functions other than the alarm function controlled by the first processing unit 1 . In addition, in the initialization method of the alarm device of the present embodiment, the initialization of the alarm device can specifically be the initialization of the second processing unit 2 . 1 and 2, the method of initializing the alarm device of the present embodiment is different from the operation of instructing execution of an operation other than the initialization of the alarm device. It includes initializing the second processing unit 2 by performing a predetermined manual operation on the receiving unit 70 (steps S11 and S22 in FIG. 6).

According to the initialization method of the alarm device of the present embodiment, the initialization of the second processing unit 2 of the alarm device is executed by manual operation by the user of the alarm device. The initialization of the second processing unit 2 is performed by resetting some or all of the constituent elements of the second processing unit 2 to the state at the time of shipment from the manufacturing factory of the alarm device, the state at the start of operation of the alarm device, or the state of the alarm device. and the external communication network are restored to the state before they were connected. Alternatively, the “initialization” of the second processing unit 2 is a specific state in which some or all of the constituent elements of the second processing unit 2 are prepared as a state after appropriate initialization of the second processing unit 2. It can be to Therefore, even if a part of the alarm device such as the second processing unit 2 does not function due to a change in the internal state, the alarm device can be put into a state where it can function normally under the will of the operator such as the user. can be restored.

Further, in the method of initializing the alarm device of the present embodiment, the second processing unit 2 can Initialized. That is, the receiving unit of the alarm device initialized by the method for initializing the alarm device of the present embodiment also receives an operation instructing execution of an operation other than the initialization of the second processing unit 2 . Therefore, it is possible to instruct a small number of receivers 70, for example, an alarm device having only one receiver 70, to perform two or more types of operations including initialization of the second processing section 2. FIG.

The initialization of the second processing unit 2 executed by the method for initializing the alarm device of the present embodiment is performed by, for example, being incorporated in the second processing unit 2 as described above for the alarm device 100 of one embodiment. It may be the initialization of the existing software SW. Further, the initialization of the second processing unit 2 changes the internal state of the second processing unit 20 that constitutes the second processing unit 2, which has been changed after the operation of the alarm is started, to a specific point in time before the change. It can be to return to a state. The “predetermined manual operation” executed in the alarm device initialization method of the present embodiment may be the same as the “predetermined manual operation” exemplified for the alarm device 100 of one embodiment. It may be a tactile switch being pushed for a specific time or longer, or a tactile switch being pushed a specific number of times or more within a specific time. In addition, in the method of initializing the alarm device of the present embodiment, the "operation for instructing execution of an operation other than initialization of the alarm device" is any form of operation on the reception unit 70 other than the "predetermined manual operation". could be.

In FIG. 6, in the second processing unit 2, an operation other than initialization is performed by a manual operation to the reception unit 70 in a manner different from the predetermined manual operation, for example, communication with the external device E or external A link setting with the device E and the like are performed (step S21). When the user of the alarm or the like notices a malfunction of the alarm, he/she performs a predetermined manual operation on the reception unit 70 in a manner different from the operation of instructing execution of an operation other than initialization of the alarm (step S11). . Initialization is executed in the second processing unit 2 by a predetermined manual operation (step S22).

As shown in FIG. 6, the method of initializing the alarm device of the present embodiment further includes connecting or disconnecting the power plug 61 of the alarm device and the commercial power supply together with a predetermined manual operation on the receiving unit 70. You may stay (step S12). The connection or disconnection between the power plug 61 and the commercial power supply may be performed before a predetermined manual operation on the reception unit 70, may be performed after the predetermined manual operation, or may be performed simultaneously with the predetermined manual operation. may be broken. Preferably, the second processing unit 2 is initialized by connecting or disconnecting the power plug 61 from the commercial power source while a predetermined manual operation is being performed. Unintended and erroneous initialization of the second processing unit 2 can sometimes be prevented.

In FIG. 6, as long as step S11 is not performed, or unless step S12 is performed together with step S11, the second processing unit 2 performs an alarm function such as, for example, a communication function or a voice utterance function based on received information. It continues to demonstrate the control function of functions other than In addition, every time an operation instructing execution of an operation other than initialization of the alarm device is performed on the reception unit 70, the second processing unit 2 performs an operation other than the initialization instructed by the operation. Execute (step S21).

It should be noted that the embodiments disclosed this time should be considered as examples and not restrictive in all respects. The scope of the present invention is indicated by the scope of the claims rather than the description of the above-described embodiments, and includes all modifications (modifications) within the scope and meaning equivalent to the scope of the claims.

For example, as a modification of FIG. 1, the alarm device 100 may include three processing units, which are semiconductor devices such as microcomputers and ASICs.
