The detailed description of the three preferred embodiments of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Referring to Fig. 2' is a first embodiment of a monitoring system for a riverbed structure according to the present invention. The monitoring system 100 is used to monitor the structural changes of the riverbed 200 after the long-term erosion, collapse (4), and (4) of the earth-rock flow, the rainwater, and the river water. In the present embodiment, the monitoring system 1〇〇 is particularly used to monitor the structural changes of the riverbed 2〇〇 under the water surface near the bridge pier 310 (for example: scouring depth, • depth of reentry, etc.) and river water 4〇〇 The flow rate to grasp the bridges in the vicinity of the bridge 1 200 change, and timely issued a warning to ensure the safety of vehicles and pedestrians passing the bridge 300. The monitoring system (10) includes a monitoring slit 1 embedded in the river bed fan near the bridge sign 310 and connected to the bridge, and a signal picking device 2 disposed on the bridge 300. Referring to FIG. 3 and FIG. 4 The monitoring device 10 includes an H-type support unit 1, a plurality of collision avoidance units 2, and a plurality of monitoring units 3. The H-type support unit 1 is an H_shaped steel frame (H_beam), but it is not limited thereto, and any material having a shape of a Η type and capable of being supported and fixed may be used. The H-shaped support unit 1 is at least partially embedded in the riverbed 2 beside the pier 310, and is connected to the pier 31〇 by a plurality of support frames 30 (or steel frames) to prevent the H-type support unit 1 from being washed away by the river 400 And move. In addition, the longitudinal direction of the H-shaped support unit i

8 1375743 The direction is parallel to the longitudinal direction of the pier 3), and has two opposite side plates i4 and a partition 12 connecting and spacing the side plates 14, and forming a front between the front and rear of the partition i2 and the two side plates 14. a recessed portion 11.

The anti-collision single 7L 2 is a live (four) concrete (RPC), or any wear-resistant material such as a stainless steel frame made of stainless steel or a plastic frame, etc., to "protect" the monitoring unit it 3 to avoid being in the river side. Damage caused by the impact of stones or drifting objects. The collision avoidance unit 2 has three walls: a top wall 21, a side wall 22 and a bottom wall 23. The top wall 21 and the side wall 22 are composed of a plurality of pillars. The bottom wall 23 is a substrate, and the collision avoidance unit 2 is installed in one of the recesses u of the H-type support unit 1, so that the three walls and the crucible The partitions 12 of the type of support unit 1 collectively define an accommodation space. In the present embodiment, the number of the collision avoidance units 2 is five, and all of them are installed in the same recessed portion 11 but the position and number of the installation are not limited thereto.

The number of the monitoring units 3 corresponds to the collision avoidance unit 2, and one-to-one is disposed in the accommodating space of the collision avoidance unit 2, and there are many methods of setting them: sticking, locking, binding, and the like. In this embodiment, the monitoring unit 3 has a generator (generat〇r) 31 operating in water, such as an alternating current or a permanent magnet motor (Permanent-Magnet Motor) or a disk motor, etc. A printed circuit board (pcb) 32 is connected to the generator 31, and in FIG. 4, the 'generator 31 is illustrated by a permanent magnet motor 31. The permanent magnet motor 31 has a turntable 310, a sensing circuit 311, and a calculation. The circuit 312, the turntable 310 is rotated by the flushing water flow of the river 400, so that the permanent magnet motor 31 can generate electric power (1 〇 3 〇 watts) for supplying the entire monitoring unit 3, if the permanent magnet motor 31 is located in the river 400 The flow of the water of the river 400 is relatively large, and the faster the speed of the 9 1375743 turntable 310, the greater the frequency and amplitude of the sensing signal; otherwise, if the permanent magnet motor 31 is located in the soil of the river bed 200, the water flow of the river 400 is washed. If the force is small, the rotation speed of the turntable 310 is slow, and the frequency and amplitude of the sensing signal are also small. In addition, the sensing circuit 311 generates a sensing signal according to the intensity of the flushing water flow of the river 400, and the degree of structural change of the riverbed 200 can be known by analyzing the sensing signal, and the calculating circuit 312 can simultaneously rotate the turntable 3 10 The rotation speed is calculated, so that the scouring speed of the river water can be known. Therefore, the permanent magnet motor 31 of the present embodiment has three functions: power generation, generating a sensing signal representing the flow intensity of the scouring water of the river water 400, and measuring The scouring speed of the river 400. The printed circuit board 32 is provided (electrically connected) with at least one sensing element 33 and a signal transmitter 34. The sensing element 33 is used to sense an environmental parameter in the structure of the riverbed. In the present embodiment, the sensing element 33 is an aCCelerometer 33. The acceleration sensor 33 utilizes its body to be moved or rotated by the flow of the flushing water of the river 400 to cause its internal structure to shift, thereby sensing changes in the internal acceleration of the river 400 and the river bed 200. Further, the acceleration sensor 33 can also be applied to a tilt angle sensor for outputting a sensing signal corresponding to the tilt angle depending on the tilt angle of the structure of the river bed 200. It is worth mentioning that both the permanent magnet motor 31 and the acceleration sensor 33 can analyze the flow intensity of the flushing water of the river 400. In this embodiment, the sensing signals and environmental parameters emitted by the two are simultaneously received and analyzed. Increase the accuracy of the analysis results. Of course, only receiving the sensing signal can also achieve the effect of analyzing the intensity of the flushing water of the river 400, in other words, the monitoring unit.

In 10 1375743, only the generator 31 can be used without the device sensing element 33, and the sensing signal can also be used for the analysis of the riverbed 200, so it is not limited to this embodiment. Furthermore, the printed circuit board 32 can be integrated with various sensing elements B such as a temperature sensor and a humidity sensor in response to the structural requirements of the river bed. The signal transmitter 34 is configured to transmit the sensing signal and the environmental parameters to the signal capturing device 20, and the signal is transmitted by using a wireless radio frequency (RF) technology, and of course, an infrared, bluetooth (bluetooth) It is transmitted by means of wired transmission, and is not limited to this embodiment. In addition, referring to FIG. 5, the signal transmitter 34 can also be independently mounted on the H-type standard single unit 1, and each monitoring unit 3 can be electrically connected to each other through the transmission line 4 () for transmitting the sensing signal. And the environmental parameters, and all the sensing signals and environmental parameters are uniformly transmitted by the signal transmitter 34 to the signal capturing device 20 for analysis, so that only one signal transmitter 34 needs to be installed in this manner. Specifically, if the signal transmitter 34 is provided in the manner of FIG. 5, in order to prevent the signal transmitter 34 from being damaged by the drift of the drift in the river 4 (8), the collision avoidance unit 2' may be added outside the signal transmitter 34. The principle and architecture are as above. However, only one monitoring unit 3 in the entire monitoring device 1 may have a permanent magnet motor 31, an acceleration sensor 33 and a signal transmitter 34. As shown in FIG. 6 , the monitoring unit 3 is installed in the uppermost collision avoidance unit 2 , and the remaining monitoring unit 3 only has the printed circuit board 32 and the acceleration sensor 33 thereon. The permanent magnet motor 31 generates power and supplies power to all the accelerometers 33, and the sensing signals and all (four) parameters of the permanent magnet motor 31 11 1375743 are transmitted to the signal capturing device 20 through the signal transmitter 34. . In summary, the above three methods, referring to FIG. 3, each of the monitoring units 3 has a permanent magnet motor 3 accelerometer 33 and a signal transmitter 34, so that each monitoring unit 3 can generate a self-generating transfer sensing signal; Each of the monitoring units 3 has only a permanent magnet motor 31 and an acceleration sensor 33, and an independently arranged signal transmitter 34. Each of the monitoring units 3 can generate electricity by itself and supply it to the acceleration sensor 33 to make it feel The measured sensing signal 'is transmitted to the signal transmitter 透过 through the transmission line 40. Referring to FIG. 6, only one monitoring unit 3 has a permanent magnet motor 31 and a signal transmitter 34, and the remaining monitoring units 3 only have a sense of acceleration. The meter 33, therefore, the permanent magnet motor 31 will supply all of the power required by the accelerometer 33, while the signal transmitter 34 is responsible for transmitting all of the sense signals. It is particularly emphasized that the number of signal transmitters 34 will be equal to or less than the number of monitoring units 3. Referring to FIG. 2 and FIG. 7, the signal acquisition device 20 includes a signal receiver 2〇1 and an analysis unit 2〇2. The signal receiver 201 is configured to receive the sensing signal sent by the signal transmitter 34 and transmit it to the analyzing unit 2〇2; the analyzing unit 202 is a computer for analyzing the structural changes of the riverbed for subsequent use. Handling and warning. Referring to FIG. 2, when the monitoring device 1 is buried at the beginning, in this embodiment, five anti-collision units 2 are buried in the riverbed 200, and only part of the H-type supporting unit 1 is exposed and is in the river 400. At this time, the acceleration sensor 33 in each monitoring unit 3 is in the river bed 200, and the water pressure it receives is more than r^s.

Xj) 12 1375743 is small, so the amplitude of the sensing signal will change within a preset range of variation; with reference to Figure 8', when a typhoon or earth-rock flow occurs, the riverbed 200 will be washed by the river 400 or with rainwater. Therefore, the uppermost monitoring unit 3 is exposed to the river bed 200 and immersed in the river water 400, so that the acceleration sensor 33 of the uppermost monitoring unit 3 is subjected to a large water pressure, so that the amplitude of the environmental parameters generated thereby Will exceed the scope of the change. The signal receiver 201 receives the sensing signal from the signal transmitter 34. Since the water pressure received by the acceleration sensor 33 in the parent monitoring unit 3 is different from the depth embedded in the river bed 200, the analyzing unit 2〇2 According to the amplitude and frequency of the sensing sil, the depth of the river bed 2' and the river 400 to the river bed 200 can be discriminated. In other words, the analysis unit 202 analyzes that the amplitude of the sensing signal emitted by the uppermost monitoring unit 3 exceeds the variation range, that is, the height of the river bed 200 has decreased from X to X'. In this way, the monitoring device 1 of the embodiment can accurately and instantly know the structure of the river bed 200 under the bridge 310, and the monitoring unit 3 is installed in the collision avoidance unit 2, which can prevent not only the stone or the heavy object. If you hit the room and the room is damaged, it will not be scattered in the riverbed 2 or the river 4 because of the scouring of the water 400. Furthermore, the permanent magnet motor 31 can generate electricity only by external pressure (water pressure), so that no additional power supply is required to save costs. Referring to FIG. 9, a second preferred embodiment of the monitoring system for a riverbed structure of the present invention is substantially the same as the first preferred embodiment, except that the monitoring list A3 of the embodiment includes A scouring unit 35, a plurality of vibrating elements 36, a printed circuit board 32, an acceleration sensor and a signal transmitter 34 are provided.

The material of the vibrating member 36 is a material having excellent piezoelectric characteristics such as lead zirconate titanate (PZT) or barium phthalate (BaTi03) and is fixed to the flushing brick 35 in a side-by-side or comb-like manner (Comb). . When the vibrating element 36 is subjected to external pressure, such as ink, the electric dipole moment (not shown) in the vibrating element 36 is shortened as the material is compressed. At this time, the vibrating element 36 is resistant to such external force. Power and sensing signals will be generated to maintain their original state. The power generated by the vibrating element 36 can be supplied to the monitoring unit 3 so that it can operate normally, and the printed circuit board 32, the acceleration sensor 33 and the signal transmitter 34 are the same as the first preferred embodiment, so no longer like Said. Referring to FIG. 10, a third preferred embodiment of the monitoring system for a riverbed structure of the present invention is substantially the same as the first preferred embodiment except that the partition 12 of the 支撑-shaped support unit 1 is worn. A plurality of perforations 13 are provided, and the number and size of the perforations 13 correspond to the permanent magnet motor (generator) 31 of the monitoring unit 3, so that each of the permanent magnet motors 31 can be respectively engaged in each corresponding perforation The permanent magnet motor 31 is prevented from flowing as the river water is washed. In addition, the type of the anti-collision unit 2 is different from the above embodiment. In the embodiment, the anti-collision unit 2 is a crash box 2 having a first hole 24 and a second The holes 25, the first holes 24, the second holes 25, and the perforations 13 of the 支撑-shaped support unit 相互 correspond to each other, and the generator passes through the second holes 25 and is fixed in the through holes 13 of the 支撑-shaped support unit 丨. When the anti-collision box 2 is exposed in the river water 400, the river water 4 〇〇 will enter the anti-collision box 2 from the first hole \ 0 14 U75743 24, and the rotating wheel 3 〇 of the permanent magnet motor μ will be rotated, and then The two holes 25 and the perforations 13 of the crucible support unit 1 flow out as indicated by the arrows of U. However, the number and position of the first hole 24 and the second hole 25 are not limited to the embodiment, as long as the river water can be inserted into the crash box 2'' to rotate the turntable 31 of the permanent magnet motor 31. Just fine.
