  Alarm transmitters include fire detectors that detect abnormal temperatures to be monitored, earthquake alarm devices that detect abnormalities in vibrations and shocks, and intruders that invade buildings by damaging them. For example, there is an alarm transmission device for crime prevention that detects the damage and prevents the spread of damage.

  Among these alarm transmission devices, a fire detector 100 with no power supply used in a general household will be described with reference to FIGS. 1 to 3. FIG. 1 is a configuration diagram of the fire detector 100, and FIG. 2 is a structural diagram thereof.

  The fire detector 100 operates with a thermoelectric power generation unit 1 that detects a temperature abnormality when a fire occurs in a monitoring target and generates thermoelectric power, and the power generation energy of the thermoelectric power storage unit 1 as a power source. The alarm transmission unit 2 determines that the determination value is exceeded and notifies the outside of the abnormality.

  The thermopile unit 1 includes a reference cold junction 11 that senses a reference temperature that is normally room temperature, and a warm junction 12 that is sensitive to flames and hot air currents during a fire.

  The alarm transmitter 2 includes a power supply circuit 21 that generates power for the alarm transmitter 2 from the electric energy generated by the temperature difference between the reference cold junction 11 and the hot junction 12 of the thermoelectric stack 1, and the thermopile Amplifying circuit 22 that amplifies the power generation amount of 1 and the output of amplifier circuit 22 are compared with threshold value Vr for determining an abnormal value of the power generation amount preset in power supply circuit 21, and a fire occurs when threshold value Vr is exceeded. It is comprised from the determination circuit 23 which determines generation | occurrence | production of this, the radio | wireless transmission circuit 24 which transmits abnormality outside when there exists the output of the determination circuit 23, and its antenna 25.

  This power generation phenomenon from the thermopile unit 1 is called the Seebeck effect and refers to a phenomenon that occurs in the circuit when both ends of different metals are connected and a temperature difference is given between the contact points.

  Therefore, as will be described later, the thermopile unit 1 has a structure in which one of the contacts is set to room temperature and the other is set to a temperature to be monitored so that power can be easily generated by a temperature difference between the contacts.

  Next, the structure of the fire detector 100 will be described with reference to FIG. As shown in FIG. 2, the fire detector 100 is usually used with a warning transmitter 2 built in a thermopile unit 1 and fixed to a ceiling 3 or the like in the house.

  The thermopile unit 1 is formed of, for example, a synthetic resin material such as ABS resin, and includes a cylindrical base 4 having ears for attaching to the ceiling at both ends of the cylindrical bottom, and a reference cold junction at the upper part of the cylindrical base 4 11, a warm joint 12 fixed to the opening at the bottom of the cylindrical base 4, and a cover 4 a of the cylindrical base 4.

  Further, one cold junction 11a of a large number of thermocouples 13 is joined to the surface of the reference cold junction 11 with high-temperature solder or silver paste suitable for the thermocouple, and the other warm junction 12a is also joined with the same adhesive. It joins to the surface of the part 12, and opposes and fixes with the cylindrical support material 15 which consists of synthetic resin materials, such as ABS resin with good heat insulation.

  The reference cold junction 11 and the warm junction 12 use a circular ceramic substrate that is inscribed in the cylindrical base 4, and one electrode 14a and the other electrode 14b when a large number of thermocouples are connected in series. The electrode 14a and the electrode 14b penetrate the ceramic substrate of the reference cold junction 11 and are inserted into the alarm transmitter 2 fixed to the upper part thereof.

  The antenna 25 of the alarm transmitter 2 is provided either on the cover 4 a or inside the cylindrical base 4.

  Then, the ears at the bottom of the cylindrical base 4 are attached to the ceiling or wall of the house where the fire is desired to be detected so that the ceramic substrate of the warm joint 12 is heated by the flame or hot air current at the time of the fire. Fix with 16.

  In addition, the thermocouple 13 is such that the temperature difference between the reference cold junction 11 that is normally placed at room temperature and the warm junction 12 that becomes a high temperature in the event of a fire is such that a predetermined output is obtained with the temperature difference desired to be sensed. Determine the type of metal and its number of connections.

  For example, various thermopiles (also called thermopiles) in which a large number of thermocouples 13 are connected in series are commercially available depending on the application. For example, there is a type T thermocouple for low-temperature measurement of JIS standards.

  When 3000 pairs of type T thermocouples are used, a thermoelectromotive force of about 3.9 V is obtained at a temperature difference of 50 ° C. when the reference cold junction 11 is 30 ° C. and the warm junction 12 is 80 ° C. .

  The thermoelectromotive force of the thermopile is stabilized by the power supply circuit 21 and supplied to the amplification circuit unit 22, the determination circuit 23, and the wireless transmission circuit 24.

  Next, the operation of the non-powered fire detector 100 configured as described above will be described with reference to FIG. FIG. 3A illustrates a state in which the temperature junction 12 is overheated by a fire flame or a hot air flow, and a temperature difference occurs between the reference cold junction 11 and the warm junction 12.

  As a result, as shown in FIG. 3B, the thermoelectromotive force between the electrode 14a and the electrode 14b connected in series increases as the temperature of the hot junction 12 increases and the temperature difference increases. .

For example, as shown in FIG. 3C, when the thermoelectromotive force becomes V ₀ or more, the voltage stabilized by the voltage stabilizing circuit 21 is supplied to each internal circuit.

  Next, after power is supplied from the stabilized power supply circuit 21, the determination circuit 23 determines whether the output of the amplification circuit 22 that amplifies the thermoelectromotive force between the electrodes 14a and 14b and the presence or absence of a fire. The presence or absence of a fire is determined by comparing with the threshold value Vr.

  Then, as shown in FIG. 3 (d), a fire alarm output is transmitted from the wireless transmission line circuit 24 to a predetermined base station (not shown) via the antenna 25.

  Note that the alarm transmission unit 2 except the amplifier circuit 22 and the determination circuit 23, immediately outputs an alarm from the wireless transmission circuit 24 when the output from the power supply circuit 23 becomes equal to or higher than a predetermined value that enables the wireless transmission circuit 24 to operate. It is also possible to use a simple configuration that transmits a message.

  According to the first embodiment, when a predetermined temperature difference occurs in the thermopile unit 1 due to a fire, the alarm transmission circuit 2 operates using the thermoelectromotive force as an energy source, and an abnormality can be transmitted to the outside. It is possible to provide a fire detector 100 without a power source that requires no wiring or maintenance.

  Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a block diagram of the intrusion detection device 110 with no power supply according to the present invention.

  The intrusion detector 110 includes a piezoelectric unit 5 that generates piezoelectric power when subjected to impact and vibration, which will be described in detail later, and an alarm transmission unit 6 that operates by the piezoelectric power generation energy of the piezoelectric unit 5.

  This power generation phenomenon of the piezoelectric part 5 is also called a piezo effect. In the piezoelectric part 5, a piezoelectric compound and a vibration plate are integrally formed by compressing and firing a metal compound that causes dielectric polarization when an external force is applied, for example, a metal oxide powder. By using a molded piezoelectric bimorph element, the structure described later is set so that the external force of the impact / vibration from the monitoring target can be easily detected.

  The alarm transmission unit 6 includes a power supply circuit 61 for operating each circuit of the piezoelectric unit 5 from the piezoelectric electromotive force of the piezoelectric unit 5, an amplification circuit 62 for amplifying the piezoelectric electromotive force of the piezoelectric unit 5, and the amplified piezoelectric electromotive force. A judgment circuit 63 for judging whether or not there is an impact / vibration due to intrusion by comparing the output with a preset threshold, and an alarm transmitter 64 for transmitting an abnormality to the outside when there is an output of the judgment circuit; And its antenna 65.

  The power supply circuit 61 includes a rectifier circuit 61a that rectifies the piezoelectric electromotive force of the piezoelectric unit 5, a capacitor 61b that smoothes the rectified piezoelectric electromotive force, and outputs from both ends of the capacitor 61b to each circuit of the piezoelectric unit 5. A voltage stabilizing circuit 61c that stabilizes the power to be supplied at a predetermined value.

  Next, the configuration of the piezoelectric unit 5 will be described with reference to FIG. FIG. 5A is a perspective view of a state in which the base plate 52a of the piezoelectric portion 5 is fixed and attached to the inside of the window 81a of the house where the intrusion detector 110 is locked, as viewed from the upper side.

  In the case of an aluminum sash door, the window 81a and the door 81b are usually equipped with various crescent locks 7 for preventing intruders. However, an intruder into the house enters the door so that the crescent lock 7 can be reached by using some breaking means in order to unlock the crescent lock 7 and enter the house.

  Therefore, the intrusion detector 110 is provided in a place where it is easy to detect the impact / vibration generated when the window 81a is broken.

  Although FIG. 5 illustrates the case where it is provided at the center of the door, the attachment position may be a location where impact and vibration are likely to be applied due to the initial action of destruction.

  Next, the structure of the intrusion detector 110 will be described with reference to FIG. FIG. 5B is a cross-sectional view seen from the side of the window 81a. The piezoelectric unit 5 includes a base plate 52a to which the piezoelectric bimorph element 51 is attached, and a pendulum plate 52b facing each other so as to sandwich the base plate 52a and the piezoelectric bimorph element 51.

  Then, the hinge 55 is fixed to the upper part of the base plate 52a, one upper part of the pendulum plate 52b is fixed to the rotation side of the hinge 55, and the pendulum plate 52b is configured to easily rotate with the hinge 55 as a fulcrum.

  Further, a weight 53 is attached to the lower part of the pendulum plate 52b, and when an impact / vibration is applied to the base plate 52 from the outside of the window 81a, the pendulum plate 52b rotates as shown by a broken line, and the piezoelectric bimorph element 51 is provided. The vibration system is such that a shock is applied multiple times.

  The alarm transmission circuit 6 is provided with a gap above the piezoelectric bimorph element 51 so that an impact from the pendulum plate 52b is difficult to be applied, and is fixed to the base plate 52a via a vibration isolating material (not shown).

  In addition, some piezoelectric bimorph elements 51 can obtain a piezoelectric output of several tens of volts and several mA even with a normal door opening / closing impact, so that the piezoelectric bimorph element can be maintained for a predetermined time by the impact. The element 51 is lengthened in the vertical direction, and a weight 53 is provided at the tip thereof. The shock at the tip of the pendulum plate 52b causes vibration for 1 second or longer and for the time necessary for sending the alarm signal from the alarm transmission circuit 64. Configure to continue.

  Next, the operation of the intrusion detector 110 configured as described above will be described with reference to FIG.

  FIG. 6A schematically shows the output of the piezoelectric electromotive force when an impact is applied to the piezoelectric bimorph element 51. Since the polarity of the output of the piezoelectric electromotive force changes, it is rectified by the rectifier circuit 61a and then stored in the capacitor 61b. Then, the stabilized power is supplied to each part of the alarm transmission circuit 6 from the voltage stabilization circuit 61c with a predetermined accuracy.

  After the power is supplied, the determination circuit 63 compares the output of the amplification circuit 62 that amplifies the piezoelectric electromotive force with the threshold values Vr + and Vr− that are set in advance, and determines whether or not there is an impact corresponding to the intrusion. Determine.

  When the output of the amplifying circuit 62 exceeds the threshold value Vr + and the threshold value Vr−, it is determined that there is an intrusion, and the alarm transmission circuit is delayed after time td3 after the time required for the determination operation of the alarm transmission circuit after power is supplied. An abnormality is notified from 64 to a predetermined base station (not shown) via the antenna 65.

  According to the second embodiment, when an impact / vibration of a house door or the like is detected by the piezoelectric unit 5 and a predetermined piezoelectric electromotive force is generated, the alarm transmission circuit 6 is activated by using the piezoelectric electromotive force as an energy source. It is possible to provide a power-free intrusion detector 110 that can transmit an abnormality to the power supply and does not require power supply wiring or maintenance.

  The alarm transmitter 6 except the amplifier circuit 62 and the determination circuit 63 immediately alerts the radio transmitter circuit 64 when the output from the power supply circuit 613 becomes equal to or higher than a predetermined value at which the radio transmitter circuit 64 can operate. It is also possible to use a simple configuration that transmits a message.
