Description

  The present invention relates to a disaster prediction sensor having an autonomous function.

  Among the devices, disaster sensors are used in professional areas such as administrative monitoring of landslides and civil engineering construction, so they display sensor information such as simple tilt sensors, vibration sensors, and water flow sensors. Just enough for practical use.

  However, landslides do not occur only at 330,000 landslide hazard sites nationwide and civil engineering construction sites that are monitored by the government, but the probability of guerrilla heavy rain occurring due to recent abnormal weather increases, and it also occurs on private land The emergence of disaster prediction sensors that can be used even by amateurs is awaited.

  In using a disaster sensor, a big difference between a professional and an amateur is that an amateur cannot predict whether or not it is dangerous even if a numerical value is displayed. In the new disaster prediction sensor device, it is necessary to solve these problems. It is said that there are signs of landslides, and many research reports have been published that can determine the presence or absence of landslides with a high probability by recognizing changes in the field situation. In addition, it is not possible to determine where the landslide will occur. To do so, it is necessary to monitor a wide range of danger. Furthermore, there are situations where it is impossible to connect a power line or a communication cable to an outdoor disaster prediction sensor. In addition, having an amateur purchase a device that involves construction is a major obstacle to popularization.

As measures to improve this, it is easy to think of methods such as battery-powered current equipment or wireless communication mechanisms. However, there are methods that can be used by the person (amateur) living in the hazardous area, and a wide range of dangerous areas. There are still insufficient ways to manage each other.

  The problem to be solved is to provide information that can be used to judge whether or not there is a landslide disaster intuitively with sound or light. Can be monitored.

  The present invention provides a sensor information that is driven by a solar cell and has a plurality of function sensors and a communication mechanism, and a plurality of disaster prediction sensors communicate autonomously to collect sensor information in a parent device by a relay method. When the parent device detects an empirical abnormality obtained by experiment or the like in the change from the steady-state information, the parent device uses light and sound to notify the danger. Furthermore, the information of the parent device is added to the location information obtained by the GPS sensor provided in the parent device, and the detection information is transferred to a remote civil engineering management center using an existing data communication network communication device. The function to monitor landslides over a wide area can be demonstrated.

The disaster prediction sensor of the present invention operates by simply installing a disaster prediction sensor in several places where there is a risk of landslide without worrying about the drive power supply, and autonomously transmitting information. Start collecting. The disaster prediction sensor parent device receives and collects sensor information of all disaster prediction sensors by the relay communication method. When the collected information exceeds a pre-programmed value, an alarm is issued and danger avoidance is urged.
In addition, by transferring information to a centralized center such as a government agency via the data communication mechanism of an existing telecommunications carrier installed in the disaster prediction sensor parent device, wide-area sediment disaster monitoring can be performed collectively and reliably. In addition, a warning can be issued to the local residents.

  The disaster prediction sensor housing (housing) is desirably small and cylindrical so that all directions can be monitored. A universal joint is used between the housing and the pile driven into the ground to secure the housing. The solar battery installed on the upper surface of the disaster prediction sensor can be installed in the direction of sunlight.

  FIG. 1 is an overall view of a disaster prediction sensor according to the present invention. Reference numeral 3 denotes a mounting bracket for a main body, 4 is a universal joint, and 5 is a pile-shaped shaft driven into the ground. For installation, after driving 5 shafts into the ground, 1 body is attached using 3 mounting brackets. The reason for separating the main body and the shaft was to not damage the main body during installation, and to make it easier to replace the main body at the time of failure.

  FIG. 2 is an overall view of the disaster prediction sensor main body, wherein 6 is a central processing mechanism including a memory, 7 is a wireless network communication mechanism, and 8 is a plurality of functional sensors. Miniaturization is realized by dividing the interior of the housing into two layers and mounting the components in three dimensions.

  In FIG. 3 (example), a plurality of disaster prediction sensors 1a, 1b, 1c installed on slopes operate autonomously, acquire information on each sensor, 1a is 1b, 1b is 1c itself 1c relays all the sensor information relayed to 10 disaster prediction sensor parent devices.

The 10 disaster prediction sensor parent devices that have received all the sensor information compare the collected information with the steady state information value, and when this value reaches an empirical abnormal value obtained through experiments, etc., it is predetermined. According to the program, the display unit 11 informs by flashing light such as LED light emission, and also emits sound from the 12 speakers and issues an alarm using the sound.
Furthermore, the 10 parent devices combine the sensor information that issued the alarm and the position information obtained by the 14 GPS sensors, using the 13 communication antennas, and using the data communication mechanism of the existing telecommunications carrier. The disaster prediction warning information will be transferred to the remote civil engineering center, etc. to contribute to wide-area sediment disaster monitoring activities.

In addition to the purpose of protecting human damage from landslide disasters, the present invention, disaster prediction sensor can be installed in the garden of ordinary households to detect suspicious persons and know changes in the environment in factories and offices. It can be used in a wide range of fields.

It is a general view of a disaster prediction sensor. It is sectional drawing of a disaster prediction sensor. It is a disaster prediction sensor figure. (Example 1)
