Description

  The present invention relates to an alarm device, and more particularly to an alarm adjustment method for setting, for example, a function of removing a plug before an alarm device of a different model, and an alarm device to which this adjustment method is applied.

  Conventionally, there is an alarm device disclosed in, for example, Japanese Patent No. 4721664 (Patent Document 1). This alarm device is operated by a commercial power source. For example, when a gas leak is detected and an alarm is output, a no-voltage output is performed to a gas meter or the like to shut off the gas.

  In addition, the alarm device includes a model that outputs an alarm with a voice message (voice system type) and an inexpensive model that outputs an alarm with a buzzer sound (buzzer system type). Further, some of these alarm devices have a plug omission detection function.

Japanese Patent No. 4721664

  By the way, in alarm devices of different models, it is considered to realize a common wiring board and a common firmware (processing program) mainly for the purpose of cost reduction. However, in such a case, it is necessary to distinguish between the operations of both models so that they can be appropriately operated in actual use and manufacturing processes.

  For example, alarm devices that do not handle plug disconnection are common, but in models equipped with a super capacitor (capacitor with large charge capacity), when a plug disconnection is detected, a voice message is output and the external A non-voltage output (hereinafter also referred to as “plug disconnection process”) such as turning on an external output for 2 seconds to the device can be performed. The model without a supercapacitor cannot simply perform the “plug removal process”.

  It is an object of the present invention to allow the first type alarm device and the second type alarm device to operate with the same processing program and to perform an operation suitable for the model.

  The method for adjusting an alarm device according to claim 1 is provided with a first type alarm device that operates by being connected to a commercial power supply and includes a power backup capacitor and outputs sound when the plug is disconnected, and a power backup capacitor. A second type of alarm device that is set to operate according to the same processing program having a process for each model and includes a storage means capable of storing a model identification code. About the alarm device and the second type of alarm device, an adjustment method of the alarm device for adjusting the first type of alarm device and the second type of alarm device by an external computer in an adjustment mode before shipment, In the adjustment mode before shipment, the external computer captures the model information of the alarm device from the alarm device connected to the external computer, An identification code indicating the type information, characterized in that to be written in the storage unit of the alarm.

  The alarm device of claim 2 is the first type of alarm device adjusted by the alarm device adjustment method of claim 1, wherein the processing program includes a step of plug disconnection processing and is written in the storage means. The identification code is the identification code of the first model, and the plug removal process is executed when the plug removal is detected.

  An alarm device according to a third aspect is the alarm device according to the second aspect, characterized in that an audio output and a no-voltage output to an external device are performed in the plug removal process.

  The alarm device of claim 4 is the second type of alarm device adjusted by the alarm device adjustment method of claim 1, wherein the processing program includes a step of plug disconnection processing, and is written in the storage means. The plug disconnection process is skipped when the identification code is the identification code of the second model.

  According to the first aspect of the present invention, the first type alarm device and the second type alarm device adjusted in the adjustment mode before shipment operate with the same processing program and are written in the storage means. Since the processing according to the type of the alarm device is performed by the identification code, it operates reliably without malfunction.

  According to the second and fourth aspects of the invention, both the first type of alarm device and the second type of alarm device can appropriately cope with the disconnection of the plug.

  According to the invention described in claim 3, in the first type of alarm device, it is possible to notify the external device such as a microcomputer gas meter with no-voltage output when the plug is disconnected.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a main part block diagram of a first type alarm device A of the embodiment, and FIG. 2 is a main part block diagram of a second type alarm device B of the embodiment. The first type of alarm device A and the second type of alarm device B of this embodiment are gas leak alarm devices that detect a gas leak of LP gas or city gas and issue an alarm.

  As shown in FIG. 1, the first type of alarm device A includes a control unit 10, a power supply circuit 11 connected to commercial AC power via an insertion plug 11 a, and a power failure that detects a power failure monitoring voltage from the power supply circuit 11. A monitoring circuit 12, an EEPROM 13 as "storage means", a gas sensor 14 for detecting gas leakage, an LED 15 for performing status display and alarm display, and an audio output circuit 16 for outputting audio from a speaker 16a; A communication interface (I / F) unit 17 for communicating with the personal computer 100 as an “external computer” before shipment, an external output circuit 18 for outputting no voltage to an external device such as a microcomputer gas meter (not shown), It has. Further, the first type of alarm device A includes a large capacitor 11b, which is a supercapacitor, in the power supply circuit 11.

  The second type of alarm device B shown in FIG. 2 has substantially the same configuration as the first type of alarm device A. The second type of alarm device B differs from the first model of alarm device A. The power circuit 11 is not provided with a large capacitor 11b. The power failure monitoring circuit 12 in the first type of alarm device A detects the divided voltage (3.1 to 4.1 V) of the switch power supply voltage of the power circuit 11 as a power failure monitoring voltage, and in the second type of alarm device B. The power failure monitoring circuit 12 detects the pull-down (1 V or less) of the power supply circuit 11 as a power failure monitoring voltage. Other elements are the same as those of the alarm device A of the first model.

  In the first model alarm device A and the second model alarm device B, the control unit 10 is configured by a microcomputer including a CPU 10a, a ROM 10b, a RAM 10c, and the like. The CPU 10a performs various processes according to a processing program described later stored in the ROM 10b and data stored in the EEPROM 13. The RAM 10c is a readable / writable memory having a work area used in various processes in the CPU 10a, a data storage area for storing various data, and the like.

  Here, the processing program stored in the ROM 10b is the same program in the first model alarm device A and the second model alarm device B. Further, in the adjustment mode of the manufacturing process (before shipment) of the alarm devices A and B, an identification code indicating the “first model” is stored in the EEPROM 13 of the first model alarm device A. The EEPROM 13 of the two types of alarm devices B stores an identification code indicating this “second model”. When executing the processing program of the ROM 10b, the identification code of the EEPROM 13 is determined and processing corresponding to each model is performed.

  With the above configuration, the first model alarm device A and the second model alarm device B perform the following processing in the normal monitoring mode. In the first type of alarm device A, when the gas sensor 14 detects the occurrence of gas leakage, the lighting control of the LED 15 and the sound output and sound output by the sound output circuit 16 and the speaker 16a are performed to notify the alarm and the external output The circuit 18 outputs no-voltage to the external device. Further, in the second type of alarm device B, when the gas sensor 14 detects the occurrence of gas leakage, the lighting control of the LED 15 and the output of the alarm sound by the audio output circuit 16 and the speaker 16a are performed.

  Further, the first model alarm device A and the second model alarm device B are subjected to device setting processing through communication with the personal computer 100 in the adjustment mode of the manufacturing process (before shipment). For this communication, various request messages are transmitted from the personal computer 100, response messages are transmitted from the alarm devices A and B to the request message, and various device settings are performed.

  When the first type of alarm device A and the second type of alarm device B are installed at a place to be monitored, the plug 11a is inserted into a commercial AC power outlet, and at this time, an initial delay operation is performed. In this initial delay operation, each circuit unit is inspected at the inspection time, and the status is displayed by lighting the LED 15 at the status display time. The initial delay time for performing this initial delay operation is set in the adjustment mode, and is set to 15 seconds for the first type of alarm device A and 5 seconds for the second type of alarm device B. Each of these times is stored in the EEPROM 13.

  FIG. 3 is a flowchart of setting processing related to the plug removal processing function in the adjustment mode in the personal computer 100. When this setting process is performed, the alarm devices A and B are connected to commercial AC power via the plug 11a, and the circuit voltage is stable. First, the personal computer 100 detects the air base output in the gas sensor 14 of the alarm device A (or B) and writes the output in the EEPROM 13 in step S1. Next, in step S2, the alarm device A (or B) is requested to receive power failure monitoring voltage data in the power supply circuit 11, and in step S3, the power failure monitoring voltage data is received.

  Next, in step S4, the received power failure monitoring voltage is determined, and processing corresponding to the value of the power failure monitoring voltage is performed. If the power failure monitoring voltage is less than 1.0 V, in step S5, an identification code indicating the second model is written to the EEPROM 13 of the currently connected alarm device (in this case, alarm device B), and in step S6, the initial code Write to the EEPROM 13 with a delay time of 5 seconds. If the power failure monitoring voltage is in the range of 3.1 to 4.1 V, in step S7, an identification code indicating the first model is written in the EEPROM 13 of the currently connected alarm device (in this case, alarm device A), and In step S8, the initial delay time is set to 15 seconds and written to the EEPROM 13. Thus, in this embodiment, it is determined whether it is the first model or the second model based on the power failure monitoring voltage. That is, in this example, the power failure monitoring voltage is “model information”.

  FIG. 4 is a main part flowchart of a processing program stored in the ROM 10b executed by the alarm devices A and B. This processing program is started when the plug 11a is connected to commercial AC power at the place where the alarm devices A and B are installed. First, in step S11, the initial delay time of the EEPROM 14 is read and set, and the initial delay operation is started in step S12. When the set initial delay time elapses from the power-on in step S13 and the initial delay time elapses, the initial delay operation is terminated in step S14. Next, the identification code of the EEPROM 13 is determined in step S15, and if the identification code is of the first model, the charge time is processed in step S16 and the process proceeds to step S18. If the identification code is of the second model, the ringing prohibition time is processed in step S17, and the process proceeds to step S18. In step S18, the process proceeds to a normal monitoring mode process.

  FIG. 5 is a flowchart of the interrupt process when plug disconnection is detected in the normal monitoring mode (actual use), and is activated when the power failure monitoring voltage is less than 3.0 V and plug disconnection is detected. In the second type alarm device B, the plug removal process is not substantially performed as in the following process. First, in step S21, the identification code of the EEPROM 13 is determined. If the identification code is of the second model, the process returns to the original routine. If the identification code is of the first model, the power is turned on in step S22. It is determined whether 25 seconds have elapsed. If 25 seconds have not elapsed, charging of the large capacitor 11b has not been completed, and the process returns to the original routine. If 25 seconds have elapsed, charging of the large capacitor 11b has been completed. In step S23, a voice “Please do not disconnect” is output and a non-voltage output (2 seconds) is performed to the external device. Return to the original routine.

  FIG. 6 is a time chart showing an example of the initial delay operation in the first type of alarm device A. The alarm device A performs an inspection of each circuit unit in an inspection time of 3 seconds after the power is turned on, and then displays the status by, for example, bright / dark lighting of the LED 15 in the status display time of 12 seconds. When the status display time elapses, it is displayed that the charging is performed by dark lighting / extinguishing of the LED for the charging time of 10 seconds. When the charging time elapses, the LED 15 is lit dark and the normal monitoring mode is entered.

  FIG. 7 is a time chart showing an example of the initial delay operation in the second type alarm B. The alarm device B inspects each circuit unit for an inspection time of 3 seconds after the power is turned on, and then displays the status by, for example, bright / dark lighting of the LED 15 at the status display time of 2 seconds. When the status display time elapses, the ringing prohibition state is displayed by dark lighting / extinguishing of the LED for the ringing prohibition time of 10 seconds. When the ringing prohibition time elapses, the LED 15 is lit dark and the normal monitoring mode is entered.

  The first type of alarm device A includes a large capacitor 11b. The large capacitor 11b starts to be charged when the power is turned on. Therefore, the alarm device A can sufficiently charge the large capacitor 11b by increasing the initial delay time to 15 seconds. Note that if plug disconnection occurs during 25 seconds (initial delay time 15 seconds + charge time 10 seconds), which is the charging time for the large capacitor 11b, as is apparent from the interrupt processing of FIG. No processing is performed. Therefore, an operation in which audio output is interrupted in the middle or no-voltage output to an external device is interrupted is not performed.

  In the above embodiment, the power failure monitoring voltage detected by the power failure monitoring circuit is used as model information. However, any information can be used as long as it can be captured by a personal computer and can identify the first model and the second model.

   Although the case of the gas leak alarm has been described in the embodiment, the present invention can also be applied to a fire gas leak alarm or a fire alarm.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention.
