1 is a circuit diagram of a flashlight alarm device 100 that is Embodiment 1 of the present invention. FIG. It is a circuit diagram of the flashlight alarm device 200 which is Example 2 of this invention. It is a circuit diagram of the flashlight warning device 300 which is Example 3 of this invention.

  The modes for carrying out the invention are the following examples.

  FIG. 1 is a circuit diagram showing a flashlight alarm device 100 that is Embodiment 1 of the present invention.

  The flashlight alarm device 100 includes a power source 1, a storage circuit 10, a trigger unit 20, a control unit 30, a deterioration determination unit 40, and an alarm unit 50. In addition, a light emitting element FL1 which is a light emitting means is connected to the trigger means 20.

  The power supply 1 outputs a DC voltage of about 24V, for example, but may output a DC voltage other than 24V. Moreover, you may supply a power supply from the exterior, without providing the power supply 1. FIG.

  The storage circuit 10 includes switching means 11, a transformer 12, a diode 13, and a capacitor 14.

  The switching means 11 is repeatedly turned on and off by a control signal (on / off signal) output from the control means 30, and generates a substantially square wave AC voltage based on the power supply 1. That is, the switching unit 11 connects or disconnects the power source 1 to the primary side of the transformer 12 according to the control signal output from the control unit 30. The transformer 12 boosts the AC voltage output from the switching unit 11 to a voltage of about 300V. The transformer 12 may be boosted to a voltage other than 300V.

  The diode 13 performs half-wave rectification on the AC voltage boosted by the transformer 12. Instead of the diode 13, an element or circuit that performs full-wave rectification may be used. The capacitor 14 accumulates electric charges (electric energy) by the voltage rectified by the diode 13. That is, the capacitor 14 is an example of a storage unit that stores electrical energy based on a storage command (control signal) output from the control unit 30.

  The trigger unit 20 includes a switching unit 21 and a transformer 22. The trigger unit 20 is an example of a trigger unit that outputs a light emission trigger that causes the light emission unit that converts electrical energy stored in the storage unit to light based on a light emission command (trigger signal) from the control unit 30. is there.

  When the switching means 21 is turned on in response to the trigger signal, the transformer 22 causes the electric charge (electric energy) accumulated in the capacitor 14 to flow to the primary side, and at this time, the capacitor 14 serving as the accumulation means flows to the secondary side. An impulse voltage that is further boosted than the voltage between both ends of is induced. The light emitting element FL1 is a xenon discharge tube or the like.

  When receiving the fire signal from the sensor SE1, the control means 30 outputs an alarm signal (alarm instruction) to the alarm means 50 described later. Further, the control unit 30 outputs a control signal (storage command) to the switching unit 11 and further outputs a trigger signal (light emission command) to the trigger unit 20.

  The deterioration determining means 40 is a means for determining the deterioration of the light emitting element FL1, and counts the number of occurrences of the trigger signal generated by the control means 30. When this count reaches a predetermined number, the light emitting element FL1 is deteriorated. to decide.

  The alarm means 50 alerts the fire with a sound or the like when an alarm signal is input from the control means 30. When the deterioration determining means 40 determines that the light emitting element FL1 has deteriorated, the deterioration of the light emitting element FL1 is sounded or the like. It is a means to alarm.

  Next, the operation of the flashlight alarm device 100 will be described.

  When the flashlight alarm device 100 is incorporated in a fire detector, the sensor SE1 of the fire detector detects an abnormal environmental change such as a fire and notifies the control means 30 of the abnormality. As a result, the control unit 30 issues an alarm command to the alarm unit 50 that generates an alarm such as a sound, and the rare gas light emitting element (flash light) FL1 such as xenon issues an alarm.

  First, an operation for charging the capacitor 14 will be described. The control means 30 outputs an accumulation command, which is a pulse for turning on and off the switching means 11, to the accumulation circuit 10. When the switching unit 11 is turned on / off, the power source 1 and the primary side of the transformer 12 for boosting the voltage of the power source 1 (for example, 24V) are connected or disconnected. As a result, the output voltage of the power source 1 is converted, and a substantially square AC voltage is applied to the primary side of the transformer 12, and this substantially square AC voltage is boosted to, for example, 330 V by the transformer 12, Voltage is generated. The boosted AC voltage is half-wave rectified by the diode 13, applied to the capacitor 14, and electric charge is accumulated in the capacitor 14.

  Next, an operation for causing the light emitting element FL1 to emit light will be described. The control unit 30 issues a trigger signal (light emission command) to the trigger unit 20 according to the output signal of the sensor SE1 after a predetermined time has elapsed since the storage command was issued. By this trigger signal, the switching means 21 of the trigger means 20 is turned on, and the electric energy accumulated in the capacitor 14 is applied to the primary side of the transformer 22, whereby the voltage is further boosted by the transformer 22, and the 2 of the transformer 22 The impulse voltage generated on the next side is applied to the light emitting element FL1. As a result, the light emitting element FL1 starts discharging, consumes the electric energy accumulated in the capacitor 14, and emits light.

  By the way, the deterioration determination means 40 counts the number of times the trigger signal output from the control means 30 is generated, and when the count number reaches a predetermined number, determines that the light emitting element FL1 has deteriorated and issues an alarm to the alarm means 50. To do. Therefore, it is possible to automatically determine that the light emitting means FL1 has deteriorated, warn, prompt the user to replace the light emitting means FL1 at an appropriate time, and manage the deterioration of the light emitting means FL1 easily.

  In Example 1, when it is determined that the light emitting element FL1 has deteriorated, the deterioration determination unit 40 instructs the alarm unit 50 to generate an alarm, but the deterioration determination unit 40 notifies the control unit 30 and The control unit 30 may instruct the alarm unit 50 to generate an alarm.

  FIG. 2 is a circuit diagram showing a flashlight alarm device 200 that is Embodiment 2 of the present invention.

  The flashlight alarm device 200 is basically the same as the flashlight alarm device 100 of the first embodiment, but in the flashlight alarm device 100, a deterioration determination unit 40b is provided instead of the deterioration determination unit 40. An accumulated voltage detection means 60 having a Zener diode 61, resistors R1 and R2, and a transistor 62 is provided. In addition, in the flashlight alarm device 200, those given the same symbols as the flashlight alarm device 100 perform the same operation.

  The accumulated voltage detection means 60 is means for detecting the voltage across the capacitor 14. A Zener diode 61 and resistors R 1 and R 2 are connected in series, and this series circuit is connected in parallel with the capacitor 14. That is, the cathode side of the Zener diode 61 is connected to the + side of the capacitor 14. Further, the base of the transistor 62 is connected to the connection point between the resistor R1 and the resistor R2, the emitter of the transistor 62 is grounded, and the collector thereof is connected to the deterioration determining means 40b.

  The deterioration determination unit 40 b determines the amount of charge (energy amount) accumulated in the capacitor 14 based on the on / off state of the transistor 62.

  Next, operations of the deterioration determination unit 40b and the accumulated voltage detection unit 60 in the flashlight alarm device 200 will be described.

  The accumulated voltage detection means 60 compares the voltage across the capacitor 14 with the break voltage of the Zener diode 61. If the voltage across the capacitor 14 is equal to or higher than the break voltage of the Zener diode 61, a current flows through the Zener diode 61, the base potential of the transistor 62 increases, and the transistor 62 is turned on. When the transistor 62 of the accumulated voltage detecting means 60 is turned on, the deterioration determining means 40b determines that the amount of energy of the capacitor 14 has become a predetermined amount or more.

  The deterioration determining means 40b determines that the light emitting element FL1 has deteriorated when the number of times that the amount of electrical energy (the voltage across the capacitor 14) becomes equal to or greater than a predetermined value and then reaches a predetermined value reaches a predetermined number. . In other words, when the amount of electrical energy (the voltage across the capacitor 14) is accumulated and exceeds the predetermined amount and is consumed below the predetermined amount, the light is emitted once, and the number of voltage changes across the capacitor 14 is detected. Thus, the number of times of light emission of the light emitting element FL1 is estimated.

  Therefore, according to the flashlight alarm device 200, it is possible to automatically determine that the light emitting means FL1 has deteriorated, to give an alarm, and to prompt the user to replace the light emitting means FL1 at an appropriate time. Is easy to manage.

  FIG. 3 is a circuit diagram showing a flashlight alarm device 300 that is Embodiment 3 of the present invention.

  The flashlight alarm device 300 is basically the same as the flashlight alarm device 100 of the first embodiment, but in the flashlight alarm device 100, resistors R1 and R2 are provided, and control is performed instead of the control means 30. In this embodiment, the means 30c is provided, the control means 30c performs the deterioration determination, and therefore the deterioration determination means 40 is deleted. In the flashlight alarm device 300, those given the same symbols as those of the flashlight alarm device 100 perform the same operation, and the control means 30c also performs the same operation as the control means 30. A series circuit of resistors R1 and R2 is connected in parallel with the capacitor 14.

  The control unit 30 c includes an A / D converter 31, a counter 32, and a timer 33. The A / D converter 31 converts the divided voltage obtained by dividing the voltage across the capacitor 14 by the resistor R1 and the resistor R2 into digital data.

  In the flashlight alarm device 300, the control means 30c outputs the number of trigger signals for causing the light emitting element FL1 to emit light, and the control means 30c itself counts the number of output trigger signals. If the number is equal to or greater than the predetermined number, it can be determined that the light emitting element FL1 has deteriorated. In other words, the counter 32 counts the number of trigger signals output to the trigger means 20 by software, and when the count value reaches a predetermined value, the light emitting means FL1 emits light a predetermined number of times, thereby deteriorating the light emitting means FL1. Judge that

  Further, in the flashlight alarm device 300, the case where the charge (light emission energy) of the capacitor 14 for causing the light emitting element FL1 to emit is accumulated after being accumulated is regarded as one cycle, and the number of cycles is set to a predetermined number. When it reaches, the light emitting means FL1 may emit light a predetermined number of times, and it may be determined that the light emitting element FL1 has deteriorated. That is, when the output value of the A / D converter 31 becomes a predetermined value and then becomes smaller than the predetermined value, or when the output value becomes smaller than a certain value lower than the predetermined value, the light emitting means. It is determined that FL1 emits light once, and the counter 32 counts the number of times of light emission once.

  Further, in the flashlight alarm device 300, the trigger signal is counted by counting both the number of trigger signals and the number that is smaller than the predetermined value after the output value of the A / D converter 31 reaches the predetermined value. Thus, it can be confirmed that the light emitting means FL1 emits light and the capacitor 14 is discharged, and the number of times of light emission of the light emitting means FL1 can be counted more accurately.

  Furthermore, the timer 33 of the control means 30c counts the time from when the flashlight alarm device 300 is energized. When a predetermined time elapses after the flashlight alarm device 300 is installed and the energization of the flashlight alarm device 300 is started, it is determined that the light emission means FL1 has deteriorated due to aging, and the user is informed that the light emission means FL1 has deteriorated. Notice. This notification can prompt the user to replace the light emitting means FL1.

  In the fourth embodiment of the present invention, when a light emission command is output to cause the light emitting means to emit light, if it is detected that the energy stored in the capacitor 14 is not consumed, the light is emitted even though the trigger signal is generated. This indicates that the light emitting element FL1 has deteriorated. The following is an embodiment in which energy is not accumulated in the capacitor 14.

  That is, for example, in the flashlight alarm device 300 shown in FIG. 3, if the control means 30c outputs a trigger signal, it means that a light emission command has been output. In this case, the voltage at the connection point between the resistors R1 and R2 is When the control means 30c determines that the voltage does not become lower than the predetermined voltage, it can be considered that the energy accumulated in the capacitor 14 is not consumed, and thereafter, energy is accumulated in the capacitor 14. Absent. Specifically, the control unit 30 c does not send a control signal for turning on or off the switching unit 11 to the switching unit 11. As a result, energy is not accumulated in the capacitor 14, and overcharge in the capacitor 14 (accumulating means) can be prevented.

  According to the fourth embodiment, since it is determined by the amount of energy whether or not the light emitting unit FL1 has emitted light after outputting the light emission command, it can be reliably determined that the light emitting unit has not emitted light.

  Instead of the determination by the analog input by the resistors R1, R2 and the A / D conversion circuit 31, the stored voltage detection means 60 of the second embodiment may be used to input and determine an on / off signal.

  Further, each of the above embodiments may be incorporated into the base of the fire detector used when installing the fire detector. For each fire detector installation location, select whether to incorporate a flashlight alarm or not by using a base that incorporates the above embodiments and a base that does not incorporate the above embodiments. can do.

  Each of the above embodiments is not incorporated in the fire detector, but is provided separately from the fire detector, so that each of the above embodiments alarms by a fire signal from the fire detector or a fire signal from the fire receiver. It may be.
