BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, an ultrasonic wave transmitter 2 is installed at an arbitrary point of a track, a road surface, a cliff, a tunnel, a fault or the like, and emits an ultrasonic wave from there. The initial phase memory 3 receives the ultrasonic wave from the ultrasonic wave transmitter 2 and receives the ultrasonic wave at the initial stage (the ultrasonic wave transmitter 2
(When installed) and measure and store the cycle and phase.

The phase measurement 4 receives the ultrasonic waves from the ultrasonic transmitter 2 and measures the period and the phase of the received ultrasonic waves after the initial stage (current time). The phase difference measurement 5 compares the period and phase of the initial ultrasonic wave stored in the initial phase memory 3 with the period and phase of the post-initial ultrasonic wave measured in the phase measurement 4 to detect the difference. Then, the phase difference of the ultrasonic waves at the initial stage and after the initial stage is measured, and when the phase difference at that time exceeds the specified value, that is, when the phase difference equal to or larger than the specified value is measured, the logic 1 is output. The phase difference measured by the phase difference measurement 5 is above the specified value when the ultrasonic wave cannot be received due to a large movement of the ultrasonic transmitter 2.

The abnormal signal generator 6 receives the logic level signal from the phase difference measurement 5 and, when receiving the logic 1, generates a abnormal signal notifying the abnormal condition at the point and outputs it to the signal controller 7. The signal control 7 is, for example, for generating a display control signal for controlling the display of a traffic light (not shown) installed at a safe position before the point, and normally controls the display of the traffic light. The display control signal is controlled without being influenced by the control signal 6 and is controlled, but when the control signal is received from the abnormal signal generation 6, the normal control is given priority and a red display control signal is generated to display the traffic signal. Is controlled to display in red.

From these facts, at the point where the ultrasonic transmitter 2 is installed, the ultrasonic transmitter 2 moves due to anomalies (signs) such as landslides and cracks occurring before the collapse, and the phase difference is regulated. When the value is exceeded, the traffic light is displayed in red and the approaching train or car is stopped to prevent entry into a dangerous place caused by an abnormality at the point.

Further, the abnormality signal generated by the abnormality signal generation 6 for notifying the abnormality of the point is transmitted to a control center (not shown) for controlling the traveling of trains, automobiles and the like. This enables remote monitoring of the point where the ultrasonic transmitter 2 is installed, confirms the occurrence of abnormalities, and makes secondary notifications and controls for running control and ATC control of trains and automobiles. It will be possible to quickly take countermeasures such as repair of the abnormal place. Further, when the point is a fault such as an active fault, it is possible to predict (detect a sign) an earthquake due to a landslide or the like at the point and monitor it.

In addition to the slopes of cliffs, faults, tunnel ceilings, etc., the ultrasonic wave transmitter 2 is also used, for example, on bridge girders of railway and road viaducts, and others (not shown). Depending on the environment, the location or position can be selected and arranged. As a result, not only the collapse of cliffs and tunnels, the scraping of concrete, etc., but also the deformation (signs) such as cracks and lateral slips that always occur before the collapse or the scraping are detected, The control of the signal display of the traffic light, the remote monitoring of the locations where the abnormalities occur, the control of trains, automobiles, etc. at the time of occurrence, and the countermeasures such as the repair of the abnormal locations are expedited.

Further, the abnormal signal generated by the abnormal signal generation 6 is used to give an alarm or warning at the point by using sound or light or a character display such as "this abnormal occurrence / prohibition is prohibited". Improve the prevention of ingress of vehicles and passersby to the abnormal point at the above-mentioned point, etc., and also prepare this at the construction site etc. for abnormalities occurring at or upstream of it, etc. By making it possible to monitor at construction sites, etc., evacuation etc. can be swiftly performed in the event of an abnormality and danger can be prevented.

The signal control 7 from the initial phase memory 3 is
It is installed in a safe place away from the point and at a position where it can receive ultrasonic waves, and the signal transmission between other than the ultrasonic transmitter 2 is wired transmission or wireless transmission or optical transmission. Transmission means (not shown) such as transmission can be appropriately selected.

The measurement of the phase difference of the ultrasonic waves may be replaced with the measurement of the arrival time difference of the ultrasonic waves because the phase difference is also a time difference, and the movement of the point may be used instead of the phase difference. The generated frequency difference may be a frequency difference for measurement, or an azimuth angle or an angle difference such as an elevation angle or a depression angle caused by the movement of the point, or the like.

Further, the ultrasonic wave transmitter 2 is replaced with a radio wave transmitter for transmitting a pulsed electric wave or the like, and further, instead of the measurement of the phase difference of the ultrasonic waves by the phase difference measurement 5 from the initial phase memory 3, The phase difference, the frequency difference, the arrival time difference, the azimuth angle difference, or the like of the pulsed radio waves or the like caused by the movement of the point may be measured from the pulsed radio waves or the like transmitted from the radio wave transmitter.

Further, it is preferable that the measurement of the phase difference or the like is carried out at several points of the point, and the abnormal signal is generated even at one of the points when the phase difference or the like is measured. The measurement of the phase difference and the generation of the abnormal signal may be performed by the control center, and the control center is a monitoring center or a monitoring station that monitors the occurrence of abnormalities at the point.
