Definitions

  • the present invention is for electronically realizing a bell for detecting movement and generating sound.
  • the bell has a small ball in a hollow outer body made of pottery, metal, pottery, etc., and generates sound by shaking the whole.
  • the inertia of the ball in the bell works by swinging the bell.
  • the inertia force is small, the ball rolls in the body to generate a bell sound.
  • the inertia force increases, the ball jumps and the bell sounds louder.
  • the bell is often used to detect movement such as putting on a cat's collar and notifying the cat's whereabouts, or putting it on a key holder to indicate that the key has fallen from a bag.
  • the generation of the bell sound depends on the mechanical action when swinging the bell, and separates the conditions such as the acceleration threshold for generating the sound, and the magnitude and length of the generated sound, etc. And difficult to control. For this reason, when the bell is used for drop detection, since a sound is generated only for a moment, the drop may not be noticed, or a sound may be generated because the sound is generated only by a slight movement. In addition, since the bell is difficult to make it thin like an IC card, it often can not enter the wallet.
  • Non-Patent Document 1 a loss prevention tag using a wireless such as Bluetooth (registered trademark) is sold for the purpose of prevention of loss of a key or the like. Since the loss prevention tag is connected to the receiver, it is necessary to carry all the luggage attached with the loss prevention tag together with the receiver. Therefore, attaching a loss prevention tag to various packages has the disadvantage that the number of packages that must be carried at all times increases.
  • the problem to be solved is that the generation of sound in the bell depends on the mechanical action, so that the detection of acceleration and the generation of sound can not be separated.
  • the present invention is characterized in that the function of the bell is realized electronically by detecting the acceleration electronically using an acceleration sensor and generating the sound electronically.
  • Gravitational acceleration is usually applied to the acceleration sensor. When the device is dropped, there is no gravity, so that the drop of the device can be detected by the decrease of the acceleration.
  • the acceleration needs to be monitored constantly, as it is not known when the device will fall.
  • the device for drop detection needs to be battery-powered, and for convenience, it is desirable that charging and replacement of the battery be unnecessary for a long period of time.
  • the average current consumption needs to be suppressed to 10 microamperes or less.
  • the microprocessor is activated by the interrupt signal from the acceleration sensor.
  • the microprocessor monitors the progress of the subsequent acceleration and generates a sound if it determines that the device has fallen. Since the current consumption of the acceleration sensor is very small (Non-Patent Document 2), it is possible to realize the above current consumption even when operating at all times.
  • a microprocessor using an interrupt signal due to horizontal acceleration is used. Can be launched.
  • the microprocessor may be kept running at all times. In this case, the interrupt signal from the acceleration sensor may not be used.
  • the threshold of the acceleration for generating the sound can be freely set. It can be set, and it is also possible to make the thickness thinner or switch on / off generation of sound.
  • the electronic bell device of the present invention when used for drop detection for preventing loss of a load, it can be attached to various loads which are not always carried by hand, so the defect of the conventional loss prevention tag It is possible to complement.
  • the electronic bell device of the first embodiment aims to detect a drop of a key or the like for preventing loss.
  • the basic concept of the first embodiment will be described with reference to the block diagram of FIG. 1, the state transition diagram of FIG. 2, and the explanatory diagram of the operation in time series of FIG.
  • the electronic bell device 100 includes an acceleration sensor 101, a microprocessor 102, and a sounder 103.
  • the interrupt signal 104 from the acceleration sensor 101 can be used to activate the microprocessor 102.
  • the SPI interface 105 is used to control the acceleration sensor 101 and read data from the microprocessor 102. Note that, instead of the SPI interface 105, an I2C interface or the like may be used. Also, instead of the sounder 103, a speaker may be used.
  • the electronic bell device 100 is in the stop state 201, and only the acceleration sensor 101 is operating.
  • acceleration is detected by the acceleration sensor 101, and when the magnitude 301 of the acceleration becomes equal to or less than the threshold 302 (or all absolute values of X, Y, Z components of the acceleration are thresholds) In the case of 302 or less), an interrupt signal 104 from the acceleration sensor 101 is generated to the microprocessor 102. As a result, the microprocessor 102 is activated, and the device enters an activation state 202.
  • the acceleration data is periodically checked via the SPI interface 105.
  • the magnitude 301 of the acceleration is close to 0, and when it collides with the ground, a large acceleration is detected.
  • the acceleration is stabilized because only the gravitational acceleration is applied. This pattern determines that the device has fallen to the ground, and the device goes into an alarm state 203 and generates an alarm sound.
  • the acceleration measured by the acceleration sensor 101 becomes unstable. As a result, it is determined that a person has picked up the electronic bell device 100, and the electronic bell device enters the stop state 201, and the alarm sound stops. If it can not be determined that a person has picked up, the timer stops the alarm sound. After stopping the alarm sound, the my processor 102 is stopped.
  • the electronic bell device according to the second embodiment is intended to replace a bell used for a cat collar or the like.
  • the circuit configuration is the same as that of the first embodiment, but the acceleration sensor 101 generates an interrupt signal 104 by acceleration in a specific direction. Therefore, the mounting direction of the acceleration sensor 101 is important.
  • a block diagram common to the first embodiment of FIG. 1, a diagram showing the direction of the acceleration sensor of FIG. 4 and an explanatory diagram of time series operation of FIG. 5 will be described.
  • the acceleration sensor 101, the microprocessor 102, the sounder 103, and the battery 402 are mounted on the substrate 401, and are suspended from a collar or the like by a hanging bracket 403 at the top of the substrate.
  • the X direction of the acceleration sensor 101 is directed vertically downward, and gravity acceleration is applied when the sensor is at rest. As it is horizontally oriented in the Y and Z directions, no gravitational acceleration is applied.
  • acceleration is applied in the Y direction or the Z direction as shown in FIG.
  • this acceleration exceeds the threshold 302
  • an interrupt signal 104 is generated and the microprocessor 102 is activated.
  • acceleration data is periodically checked via the SPI interface 105, and a bell sound is generated according to the measurement value of the acceleration sensor 101. It is also possible to reproduce the same sound as that of the bell by performing physical simulation of the motion of the outer body of the bell and the ball based on the measured value of the acceleration obtained by the acceleration sensor 101.
  • an interrupt signal 104 is generated each time the cat moves, and the microprocessor 102 starts up, so the current consumption increases, but the loss prevention of the first embodiment is prevented.
  • it is not an application that does not matter even if the battery runs out while not aware, so charging may be performed each time the battery runs out.
  • power may be supplied by using a solar cell attached to a collar, or power may be supplied by generating electricity by the movement of a cat.
  • the microprocessor 102 may be kept stopped at all times, or may not be stopped. In this case, the interrupt signal 104 for activating the microprocessor 102 may not be used. When the interrupt signal 104 is not used, it is not necessary to adjust the direction of the acceleration sensor 101 to the direction of gravity.
  • the electronic bell device according to the first embodiment can be put in a wallet by thinning as in the IC card, and can be applied to preventing the wallet from being lost due to falling.
  • the electronic bell device of the second embodiment can be used for a wind bell or the like.
