Description

  The present invention relates to a danger prevention notification or disaster prevention notification and a system for detecting an electrical signal generated by a piezoelectric element as swing detection or pressure detection.

  2. Description of the Related Art Conventionally, there is a function of emitting light or a function as a swing sensor, a method of increasing power generation efficiency, and a danger notification method by applying bending power generation of piezoelectric elements. Piezoelectric elements have the property of generating electrical pulses due to strain. Utilizing this characteristic, there are applications as shown in Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5, for example. The shape of a piezoelectric element generally used is a plate-like laminated structure in order to increase power generation efficiency, and power is generated by bending the plate-like piezoelectric element with an external force. The piezoelectric element itself is a fired body and has a low bending tolerance, and may be broken if a strain exceeding the tolerance is applied. This indicates that the variation limit is small and a large power generation cannot be expected. In addition, power generation by deformation of the piezoelectric element is not suitable for power generation because it is pulsed.

  Patent Document 1 is a flashlight that deflects a piezoelectric element with an external force and causes a light-emitting element to emit light with electric power generated at that time. This method generates electric power by a piezoelectric element by human external force to generate pulse light emission, and does not satisfy the light function of visually recognizing a shape object by irradiation. Patent Document 2 is useful for informing the presence of a person walking with a crutch by blinking and emitting light by a pulsed power generation by a piezoelectric element, but the light emitter does not emit light when the walking motion is stopped. In order to eliminate this drawback, it is also described that the surroundings are illuminated using auxiliary energy such as a battery, but it cannot be denied that it becomes the same as a normal battery type flashlight function. Similarly, Patent Document 3 applies power generation by distortion of a piezoelectric element, but it is a pulsed power generation application similar to Patent Documents 1 and 2.

  Patent Document 4 is a device that emits light from a light emitter by a power generation function of a piezoelectric element. This device is placed on a shoe sole, a pressing external force applied by a person walking is applied to the piezoelectric element, the light emitting element flashes, and the presence and danger of a person It is useful in the method of alert | reporting. Although this method describes a function of providing a storage battery and charging with a piezoelectric element, an actual piezoelectric element is suitable for generating electricity in a pulsed manner, but has no power generation capability until charging. Although Patent Document 5 is a collision prevention buoy equipped with a piezoelectric element that generates electric power by swinging with the wave of the seawater as an external force, the light emitting ability of the light emitting element is weak, and there are many aspects that are not suitable for actual danger notification.

  As described above, the function of causing the light emitting element to emit light by applying external force using the piezoelectric element is useful, but the piezoelectric element has low power generation capability, and the generated power is power supplied to a secondary battery or the like having a charging function. It does not satisfy the performance.

FIG. 1 shows both sides of a flexible plate (102) supported by a cantilever structure (108) in a casing (109) showing a mechanism diagram of a swing detection device using a piezoelectric element according to the present invention. The piezoelectric elements (101a, 101b) are attached to the substrate, and the piezoelectric elements (101a, 101b) are bent by swinging (111) by an external force to obtain a power generation pulse signal. The displacement limiter (104, 105) is useful because the piezoelectric body is a fired body and has a small strain tolerance and easily breaks when a large strain is applied, thereby preventing an increase in strain due to oscillation. Although the oscillation resonance frequency of oscillation can be controlled by the weight (103), the resonance frequency can be changed depending on the position of the piezoelectric element and the shape of the flexible plate even when there is no weight. The resonance frequency can be selected according to the frequency of the external force. 106 is a solar power generation panel, 107 is a secondary battery, and 110 is a control circuit board. The piezoelectric bodies (101a and 101b) generate pulse power by swinging deflection, and swinging can be detected.

  FIG. 2 shows the configuration of the electric control system of the embodiment shown in FIG. A power generation pulse by the piezoelectric bodies (201a, 201b) and the flexible plate (202) is rectified in both waves (203) to obtain a generated pulse (205).

The function of setting the time for causing the light emitting element to emit light or setting the oscillation information for wireless transmission time depends on the timing pulse (209). Therefore, it is possible to determine the flashing light emission and the wireless transmission time by this timing pulse (209), and to reduce secondary battery consumption (212).

This also means reducing the consumption of the secondary battery (610). A timing pulse (605) is generated by a timing pulse generation circuit (604) using the generated pulse (602) as a trigger. The time setting function for causing the light emitting element to emit light depends on the timing pulse (605). Therefore, flashing can be performed by the timing pulse (605), and consumption of the secondary battery (610) can be reduced and attention visual recognition can be improved.

Although communication between the vehicle in the tunnel and the standby vehicle outside the tunnel using a transceiver, etc. has been confirmed by the communication between the vehicle in the tunnel and the standby vehicle outside the tunnel, It is not certain and misoperation between vehicles will occur. The traffic control is performed by detecting the presence of the vehicle (1503) carrying out the earth and sand from the excavation site, the moving direction (1507) and the time by the pressing mat (1504, 1505) laid on the road in the tunnel. The vehicle information by the pressing mat at the excavation site in the tunnel is wirelessly transmitted to the display device (1507, 1508, 1511) indicating the state of movement of the vehicle to be carried out or loading operation.
