Description

  INDUSTRIAL APPLICABILITY The present invention is a generator that generates an induced electromotive force in accordance with the rotational speed, and is particularly useful for a rotation transmission mechanism to a generator having a flywheel that maintains rotational inertia, and crime prevention and health monitoring in a house. A monitoring system that uses a module that realizes window / door opening / closing detection and signal transmission by a generator equipped with the rotation transmission mechanism without using a power source and without a cable, and suppresses power consumption of the entire system, The present invention relates to a configuration and a control method of a monitoring system that reduces malfunctions.

  A generator using a motor that generates an induced electromotive force in accordance with the rotational speed is a known technique, and is used in various industries such as a manual charger for a mobile phone, a manual radio, or a dynamo for a bicycle. Moreover, since the induced electromotive force when rotation is applied to the motor is the same as the rotation time to be applied, a generator having a flywheel with a large rotational inertia force has been devised for the purpose of improving the power generation time. This is a manual charger for a mobile phone in which the electric power obtained during one operation for applying rotation is improved by adding a flywheel to a motor that generates an induced electromotive force (see, for example, Patent Document 1).

  As for the monitoring system, a module equipped with a power generation mechanism and a wireless transmitter has been installed on the windows and doors in the house to detect unauthorized door opening and closing, and an alarm device installed outside, a contract security company, the police A monitoring system having a configuration in which an alarm is transmitted to a receiving device such as a resident's mobile phone has been devised. A module consisting of a piezoelectric element and a rigid sphere facing the piezoelectric element is installed in the door, and the radio transmitter is operated using the electric power generated by the collision of the rigid sphere with the piezoelectric element due to vibration generated when the door is opened and closed. (For example, refer to Patent Document 2).

JP 2001-231234 A Japanese Patent Laid-Open No. 2004-092121

  However, in the configuration described in Patent Document 1 in which the flywheel is used as a rotary inertia holding mechanism to improve the power generation time, it is necessary to apply rotation directly to the flywheel. There was a problem that when rotation in the direction opposite to the rotation direction was applied, the rotation of the flywheel was decelerated or stopped.

  Alternatively, if the configuration in which rotation is selectively transmitted to the flywheel only when the rotation direction to be applied is a predetermined rotation direction is added, the reverse rotation energy cannot be converted into electric power. There was a problem that the electric power was small in power generation and low in efficiency.

  In the monitoring system described in Patent Document 2, as described above, the power for detecting the opening and closing of the door and the window and the wireless transmission is generated by the collision of the hard sphere and the piezoelectric element due to the vibration of the door and the opening and closing of the window. Electricity is used. However, the voltage generated in the piezoelectric element is determined only by the applied stress, excluding terms related to the shape and material of the piezoelectric element. On the other hand, the stress applied to the piezoelectric element is determined by the mass of the hard sphere and the relative velocity of the hard sphere with respect to the piezoelectric element. If the density of the hard sphere is constant, the voltage generated in the piezoelectric element is determined by the volume of the hard sphere and the module size. Therefore, there is a restriction on the module size in order to obtain a constant power, which is suitable for miniaturization. There was no problem.

  In addition, in the monitoring system described in Patent Document 2, there is no mention of an abnormality determination algorithm and a control method, and there is no description of control of the monitoring system particularly for health monitoring purposes.

  As the power generation means, an electromagnetic motor that generates an induced electromotive force in accordance with the rotation speed can be used according to the principle of electromagnetic induction.

  Further, the monitoring system has a rotary inertia holding generator in which rotation is applied to the first gear train mechanism by opening / closing operation of the openable / closable object, and the object that can be opened / closed by power generation of the rotary inertia holding generator.

  In particular, the primary detection unit is not a conventional piezoelectric element, but maintains the rotation inertia even when the rotation applied by using a mechanical rotary inertia holding generator is a reciprocating motion, and the generation time and the amount of power generation than before are maintained. In order to improve the above, the rotation direction transmitted to the generator is always constant regardless of whether the applied rotation direction is clockwise or counterclockwise.

  Further, in the above monitoring system, control is normally performed so that power is not supplied to the secondary detection unit and power is supplied to the secondary detection unit when the primary detection unit detects opening or closing of a window or door. The flow was implemented in the control unit.

  For the purpose of crime prevention, the control unit detects opening / closing of a window or door, and when the secondary detection unit detects an occupant, the occupant is determined to be an intruder and an emergency signal is transmitted.

  In addition, since the rectifier circuit is not required by adjusting the rotational direction to be mechanically constant, the voltage effect in the conventional rectifier circuit does not occur, and the power generation unit combining the generator and the constant voltage circuit is more than conventional. High efficiency can be realized.

  As for the monitoring system, by constructing a monitoring system that realizes the above-described configuration and control method, it is possible to reduce the power consumption of the entire system by constantly turning off the power supply of the entire system.

  Furthermore, in the configuration using the conventional piezoelectric element, the generated voltage is restricted by the module size and is not suitable for miniaturization, whereas in the rotary inertia holding generator of the present invention, the generated voltage is independent of the module size. , Determined by the number of revolutions applied to the generator. The gear train mechanism for introducing the applied rotational speed into the generator determines the speed increase rate depending on the gear diameter ratio, so a large speed increase rate can be obtained even when the size is small. Can be introduced into the generator, and is in principle suitable for downsizing compared to a configuration using a piezoelectric element.

  Further, in the monitoring system according to the present invention, a more reliable monitoring system can be constructed by using a determination and control algorithm for realizing a system configuration for health monitoring that is not mentioned in the prior art.

  Furthermore, by dividing the primary detection unit that generates a trigger signal by a specific operation and the secondary detection unit that operates after starting up the entire system, it detects motions other than human movement, such as flying insects. It is possible to reduce the possibility of malfunctions such as

  Further, by reducing the size of the power generation unit used for the sensor and mounting the wireless transmission function, it is possible to eliminate the need for cable wiring and to prepare for installation work.

  Embodiments of a rotary inertia holding generator and a monitoring system using the same according to the present invention will be described below in detail with reference to the drawings. Constituent elements represented by the same reference numerals in the drawings are common to the drawings and indicate the same constituent elements.

  FIG. 1 is a configuration diagram of a rotary inertia holding generator according to the present invention, which is an example of a basic form of the present invention. In FIG. 1, the gear 101, the gear 102, the gear 103, the gear 104, the gear 105, and the gear 106 constitute a first gear train mechanism.

  The transmission of rotation by the first gear train mechanism will be described in detail below. The rotation input unit in the first gear train mechanism is a gear 101, and rotation applied from the outside is first transmitted to the gear 101. The rotation applied to the gear 101 is transmitted as a reverse rotation to the gear 102 engaged with the gear 101. The gear 102 and the gear 103 are bonded and fixed, and the rotation of the gear 102 and the gear 103 is the same in both rotation speed and rotation direction. Further, the gear 103 and the gear 104 are engaged with each other, and the rotation of the gear 104 is opposite to the rotation of the gear 103. The gear 104 and the gear 105 are bonded and fixed, and the rotation of the gear 104 and the gear 105 is the same in both rotation speed and rotation direction. The gear 105 and the gear 106 mesh with each other, and the rotation of the gear 106 is opposite to the rotation of the gear 105. The gear 105 is bonded and fixed to the gear 109 using a connecting member (also serving as a spacer) 108, and the gear 105 and the gear 109 rotate in synchronization. Further, in FIG. 1, the gear 109, the gear 110, and the gear 111 constitute a second gear train mechanism. The gear 109 and the gear 110, and the gear 110 and the gear 111 are engaged with each other. The gear 109 and the gear 110 are rotated in reverse directions, and the gear 110 and the gear 111 are rotated in reverse directions.

  For example, when a clockwise rotation is applied to the gear 101 which is the rotation input unit, a clockwise rotation is applied to the gear 105, a counterclockwise rotation is applied to the gear 106, and a clockwise rotation is applied to the gear 111. Rotation is applied (however, the rotation direction of the gear is defined as the rotation direction when viewed from the left side in FIG. 1). Thus, the gear 106 and the gear 111 rotate in opposite directions when viewed from the same direction, and the rotation is transmitted to the flywheel 107 respectively. The rotation transmission from the gear 106 and the gear 111 to the flywheel 107 will be described later.

  In FIG. 1, the gear 106 rotates about a shaft 121, and the gear 111 rotates about a bearing 122 provided on a rotating shaft 123 fixed to the flywheel 107. The fixing of the flywheel 107 and the rotating shaft 123 will be described later. Further, the gears 101, 102, 103, 104, 105, 109, 110 rotate about an axis (not shown).

  Further, the gear 102 and the gear 103, and the gear 104 and the gear 105, the gear 105, and the gear 109 may be bonded and fixed as described above, or may be integrally formed.

  Next, the respective speed increasing ratios of the first wheel train mechanism and the second wheel train mechanism in FIG. 1 will be described in detail below. First, for the first gear train mechanism, the pitch from the gear 101 to the gear 106 is constant, the gear ratio between the gear 101 and the gear 102 is 5: 1, the gear ratio between the gear 103 and the gear 104 is 5: 1, The gear ratio between the gear 105 and the gear 106 is set to 4: 1, and the speed increasing ratio is 100 times. For the second gear train mechanism, the pitch from the gear 109 to the gear 111 is constant, and the gear ratio between the gear 109 and the gear 110 and the gear ratio between the gear 110 and the gear 111 are both 2: 1. Thus, the speed increasing ratio from the gear 101 to the gear 111 is set to 100 times. However, the number of gears, the gear number ratio, and the speed increasing ratio of the gear train mechanism are not limited to the example shown in FIG. 1 and can be arbitrarily set.

  The generator body 112 includes a stator (stator) 116 made of a permanent magnet and a rotor (movable element) 115 made up of a core 113 and a coil 114, and is housed in a casing 117. Further, the rotor 115 is fixed to the rotating shaft 118, and the rotor 115 rotates in synchronization with the rotation of the rotating shaft 118, and is slidably contacted with power output terminals (slip rings) 119a and 119b provided at one end of the rotating shaft 118. AC power generated via the movers 120a and 120b is taken out to the outside. The generator main body 112 shown in FIG. 1 is an example, and the configuration of the power generation portion is not limited to this. The configuration in which the stator 116 is a coil and the rotor 115 is a permanent magnet, the coreless motor, or the coil Any structure that generates an induced electromotive force by rotation, such as three, can be applied. The description of the AC power extraction method is merely an example, and any method can be applied as long as the AC power is extracted directly from both ends of the coil.

The other end of the rotating shaft 118 is provided with a flywheel 107, and the rotation is transmitted from the gear 106 or the gear 111 located at the final stage of the first gear train mechanism or the second gear train mechanism to the flywheel 107. Is done. The flywheel 107 is fixed to the rotating shaft 123, and the rotating shaft 123 is fixed to the rotating shaft 118. Furthermore, since the rotating shaft 118 and the rotor 115 are fixed as described above, when the flywheel rotates, the rotor 115 rotates in the fixed generator main body and obtains electric power from the power output terminals 119a and 119b. Next, the rotation transmission method between the gear 106 or the gear 111 and the flywheel 107 will be described in detail with reference to FIGS.

  The positions of the recesses are arranged according to the cavities provided on both end faces of the flywheel 107 described later, and are not limited to the positions shown in FIG. 2, and are arranged on the end faces. The number of recesses is not limited to that shown in FIG.

  An example of a method for fixing the protrusions to the recesses will be described in detail with reference to FIG. In FIG. 3, the protrusion 301 corresponds to the first protrusions 201a to 201d or the second protrusions 202a to 202d in FIG. 2, and the recess 302 corresponds to the recesses 203a to 203d and the recesses 204a to 204d in FIG. Rails 304 a and 304 b are formed on the inner surface of the recess 302, and the protrusions 301 can slide in the rail direction in the recesses by the guides 303 a and 303 b provided on the protrusion 301, and are restrained in the vertical direction with respect to the rail. With the above-described configuration, when the gear 106 or the gear 111 rotates, the protrusion 301 receives a centrifugal force outward in the normal direction and moves to the outside in the recess.

  The configuration of the recess is not limited to the configuration of the above-described guide and rail as long as the projection 301 can move in the normal direction of the gear and the movement is restricted in a direction perpendicular to the normal direction. .

  FIG. 4 shows both end faces and a cross-sectional view of the flywheel 107 in FIG. 403a is a front view of the end face on the gear 106 side in FIG. 1, 403b is a sectional view of the side face of the flywheel 107, and 403c is a front view of the end face on the gear 111 side in FIG. The flywheel 107 is formed with a first cavity 401 and a second cavity 402 on both end surfaces.

  The first cavity 401, the second cavity 402, or the cavities 901, 1001, 1201, and 1301 described later shown in FIG. 4 may be produced by milling or injection molding, or the size of each member. If the size is small, it may be manufactured using a semiconductor manufacturing process such as etching. Or it is not limited to the method mentioned above, You may produce with other arbitrary manufacturing methods.

  Hereinafter, the first protrusions 201a to 201d or the second protrusions 202a to 202d formed on the end faces of the gear 106 and the gear 111, respectively, and the first cavity 401 or the second protrusion formed on both end faces of the flywheel 107, respectively. A method of transmitting rotation by interference with the cavity 402 will be described in detail with reference to FIGS. 4 and 5, particularly taking interference between the first cavity 401 and the first protrusions 201 a to 201 d as an example.

  As shown in FIG. 4, the first cavity 401 has a shape having a convex portion in a fixed direction at at least one place, and is arranged on the end face of the gear 106 by the rotation of the gear 106 as shown in FIG. The flywheel 107 is configured to rotate in response to a tangential force when the projections interfere with the first projections 201a to 201d slid outward in the recesses 203a to 203d. Further, the portion other than the convex portion of the first cavity 401 has a gentle shape as shown in FIG. 4, and the gear 106 is stopped and the flywheel 107 is rotating or the gear 106 is rotating in reverse. The first protrusions 201a to 201d receive a gentle force from the first cavity 401 toward the center in the normal direction of the gear 106, so that the first protrusions 201a to 201d slide inward to rotate the flywheel 107. Will not be disturbed.

  The rotation transmission method to the flywheel 107 by the interference between the second cavity 402 and the second protrusions 202a to 202d is the rotation transmission method by the interference between the first cavity 401 and the first protrusions 201a to 201d described above. Since it is the same, it is omitted here to avoid duplication.

  As shown in FIG. 6, the first cavity 401 and the second cavity 402 provided on both end faces of the flywheel 107 have convex portions formed in opposite directions toward the respective end faces, and both rotate in the same direction. It has a structure to do. On the other hand, since the gear 106 and the gear 111 are configured to always rotate in the opposite directions, the rotation direction applied to the flywheel 107 is always a constant direction regardless of the initial rotation direction applied to the gear 101. Is possible.

  If the shape of the first cavity 401 and the second cavity 402 described above is a shape that rotates in one direction due to interference with the first protrusions 201a to 201d and the second protrusions 202a to 202d, the shape of FIG.

  Further, the power generation unit provided in the primary detection unit is not limited to a generator that converts rotational force into electric power. For example, a piezoelectric element is installed in the inside of a knob or a hinge, and power is generated by strain applied to the piezoelectric element during opening and closing. It is also possible to install a thermoelectric element on the handle of a door or window and generate power using the temperature difference caused by contacting the thermoelectric element during opening and closing. Any power generation method that can be acquired is applicable.
