In this case, the inverter 220 may increase the efficiency of the electric motor 221 by converting not only the frequency of the AC power delivered to the electric motor 221 but also an effective voltage together, and when the frequency is lowered, the voltage is also lowered together. The required degree of torque is obtained while preventing overheating of the electric motor 221, and as the frequency is increased, the voltage is also increased to prevent the torque from being lowered. That is, the inverter 220 enables the electric motor 221 to control a variable voltage variable frequency.

The driving controller 220 drives the electric motor 221 according to the current position of the driving unit 21 and the position of the sluice gate 20 to be opened and closed, and at the same time, the electric motor through the inverter 222. The braking unit 223 is controlled to control the rotation direction and the rotation speed of the 221 and to stop the driving unit 31 at the position of the gate 20 to open and close.

In this case, as illustrated in FIG. 1, two or more hydrological opening and closing devices 30 are provided on the movable table 10 to simultaneously drive a plurality of hydrological opening and closing devices 30 as necessary. There may be a risk of collision if the device 30 is traveling at the same time. Therefore, the driving unit 31 may further include a collision detection unit 224. The collision detection unit 224 is a means for detecting whether there is another water gate opening and closing device 30 within a predetermined distance in the driving direction of the driving unit 31, a device for measuring the distance using radio waves or lasers, etc. It may include.

Further, in order to stop the driving unit 31 at the correct position, the motor may output a pulse number at the time of forward / reverse rotation of the electric motor 221 such as an encoder, for example, an encoder. A position detecting unit 225 may be provided to detect the position of the driving unit 31 to count. Accordingly, the opening / closing position of each of the water gates 20 stored in advance in the travel controller 220 (for example, a position at which a line connecting the moving path of the driving unit 31 and the width direction center of the water gate in a vertical direction intersects with each other). ) By comparing the position information detected by the position detection unit 225, the traveling unit 31 is accurately stopped at the opening and closing position for the water gate 20 to be opened and closed. To this end, the travel controller 220 stores a table including the opening and closing position information for all the sluice 20, the travel controller 220 is the sluice gate 20 to be currently operated by the gate opening and closing device 30 Read the opening and closing position information of the position detection unit 225 to check the position information of the current hydrological opening and closing device 30 is detected, and compares the two while the feedback control the driving unit 31.

Accordingly, the driving controller 220 adjusts the rotational speed of the hydrological opening and closing device 30 (electric motor 221) based on the result detected by the collision detecting unit 224 or the position detecting means. The braking unit 223 may be controlled.

On the other hand, when the cylinder (33a, 33b, 33c) included in the opening and closing part 32 is composed of a screw jack, the electric motor 231 for rotating the one side of the screw jack to adjust the overall length of the screw jack is provided together In addition, the opening and closing controller 230 drives the electric motor 231 connected to the screw jack in this way to adjust the length of the screw jack. Accordingly, the opening and closing controller 230 controls the angles of the pedestal 32a, the towing 32b, and the steering wheel 32c included in the opening and closing portion 32 to the hook 32c 'formed at the end of the steering wheel 32c. ) Is hooked on the top of the sluice 20, moves the sluice 20 to the desired position, and again allows the hook 32c 'to be pulled off the top of the sluice 20.

In this case, the electric motor 231 may be provided with an inverter like the electric motor 221 provided in the driving part 31, and accordingly, the electric motor 231 may be controlled to a variable voltage variable frequency. If the rotation shaft of the electric motor 231 rotates in one direction, the total length of the screw jack is shortened, and if the rotation shaft is rotated in the other direction, the overall length of the screw jack is increased, so that the opening / closing part 32 is operated. As described above, each screw jack included in the opening and closing portion 32 is sequentially controlled to allow the opening and closing portion 32 to operate in a direction necessary for opening or closing the water gate. In this case, in order to increase the reliability of the control of the open / close controller 230, the electric motor 231 of the open / close unit 230 may include a position detecting unit 232. The position detecting unit 232 detects the current state of the screw jack, including an encoder for detecting the rotation direction and the number of rotations of the electric motor 231. Accordingly, the opening and closing controller 230 determines the direction and the speed and time to rotate the electric motor 231 connected to the screw jack according to the current state of the screw jack.

On the other hand, the hook 32c 'of the opening and closing part 32 is provided with a distance sensing unit 233 in a direction in which the hook 32c' is walked on an upper end of the sluice 20. The distance detecting unit 233 includes a photo sensor which detects a distance from an upper end of the water gate 20 by photographing an image with visible light or infrared light. Thus, the driving width of the opening and closing part 32 can be adjusted according to the upper position of the sluice 20, and if a problem occurs in the control such as an error occurs in the position detecting part 232 of the electric motor 231. Before the collision with the sluice 20, the electric motor 231 is suddenly braked to prevent damage to the sluice 20.

Here, the opening and closing part 32 may be provided with an overload detecting part 234. When the overload is detected in the opening and closing part 32, the driving of the electric motor 231 provided in each screw jack is stopped to prevent the machine from being damaged. The overload detection unit 234 may include at least one of mechanical, electronic, and electrical detection means. For example, it is the same as a general overload detection means, including a strain gauge (Strain Gauge), including a mechanical configuration such as a spring, or to detect the current flowing through the winding of the electric motor 231. When the overload is detected by the overload detection unit 234, the open / close controller 220 stops driving the electric motor 231.

Referring to FIG. 5 step by step description of the method for controlling the hydrological opening and closing device as described above and the hydrological system using the same, first, the central control unit 100 is detected in the water level installed upstream and downstream of the stream centered on the hydrological system Receiving the water level information from the unit 200 (S10) determines whether the water gate is opened or closed (S20). When determining whether to open or close the water gate, the opening and closing angle of the water gate 20 is determined together.

And when the determination is made to change the current state of the water gate, such as opening or closing the water gate in step S20 (S30), the central control unit 100 transmits a control signal according to the decision to the water gate opening and closing device 30, Accordingly, the driving controller 220 drives the electric motor 221 of the driving unit 31 to move the driving unit 31 to the position of the water gate to be opened and closed (S40).

When moving to the position of the water gate to be opened and closed, the opening and closing unit 32 operates under the control of the opening and closing controller 230 (S50). As a result, the state of the floodgate to be opened and closed is changed as desired.

Thereafter, steps S40 to S50 are repeatedly performed for the control of the other gate 20 again until the opening and closing of all the gates 20 is completed (S60).

In the case of using the hydrological opening and closing device as described above and the hydrological system using the same, it is possible to construct an inexpensive and durable hydrological system even in a wide river where a large number of hydrological gates are needed, especially in the case of utilizing an existing infrastructure such as a bridge, Efficient low cost construction of the gate is possible.

In addition, by using the control method as described above in the above-described hydrological opening and closing device and a hydrological system using the same, it is possible to control the hydrological opening and closing device automatically and remotely.
