Description

Technical Field

[0001] The present application relates to the technical field of hydropower and water conservancy engineering, and in particular to a fish-driving fence control method and a fish-driving fence control system. Background Art

[0002] While the construction of water conservancy and hydropower projects by blocking rivers and building dams has brought huge benefits to mankind in terms of electricity and water resources, it has also had a serious impact on local fishery resources. The construction of the dam body has blocked the migration path of fish, resulting in a sharp decrease in the amount of fishery resources and serious impact on fishery production. In order to protect fishery resources and reduce the impact of hydropower projects on fish, the research and application of fish driving equipment has become an important means. Among them, fish lifts (fish elevators) are common supporting fish passing facilities for high dam hydropower projects.

[0003] At present, the staff determines the timing to operate the programmable logic controller based on subjective observation, starts the motor of the fish driving fence, drives the fish driving fence forward to drive the fish. After the fish driving is completed, they observe the number of fish with their eyes. If the number is sufficient, they collect or lift the fish; if the number is insufficient, they control the programmable logic controller to retract the fish driving fence and wait for a period of time before driving the fish again.

[0004] However, since the fish-driving fence equipment is activated by staff at a scheduled time or manually, the number of fish in the fish-gathering area cannot be determined, resulting in poor fish-gathering effect. When there are many fish, it cannot be activated in time, resulting in long-term large fluid dynamic consumption of the fish targets in the fish-gathering area, causing them to leave the area or even get injured and die. When there are few fish, inappropriate startup timing will cause waste of electricity and increase equipment loss. Summary of the invention

[0078] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application. In addition, it should be understood that the schematic drawings are not drawn in real proportion. The flowchart used in this application shows the operations implemented according to some embodiments of the present application. It should be understood that the operations of the flowchart can be implemented out of sequence, and the steps without logical context can be reversed in order or implemented simultaneously. In addition, those skilled in the art can add one or more other operations to the flowchart under the guidance of the content of the present application, or remove one or more operations from the flowchart.

[0079] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0080] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0081] Damming rivers and constructing water conservancy and hydropower projects will have an adverse impact on the normal migration of fish in rivers. It not only physically blocks the natural migration path of fish, but also changes the hydrological and hydrochemical conditions of the river, affecting the survival and reproduction environment of fish. It may lead to the obstruction of fish reproduction and the decline of population, and also bring challenges to aquatic organisms that rely on river ecosystems.

[0082] At present, newly built water conservancy and hydropower projects need to build supporting fish-passing facilities to assist fish to pass through the dam, realize genetic exchange between the upstream and downstream of the dam, and avoid the decline of fish numbers and damage to the river ecological environment due to the inability of fish to migrate normally. At present, the staff can only rely on the staff to observe the number of fish in the fish-passing facilities with their eyes. When the number is sufficient, the fish are collected or lifted for processing. If the number is not enough, the staff will control the fish-driving fences to continue to collect fish. However, it is impossible to accurately identify the fish species in the fish-passing facilities through human observation, and there are certain errors in the human eye, resulting in low efficiency of the fish-passing facilities when there are fewer fish, which will cause power waste and increase equipment loss. When there are more fish, they cannot be started in time, resulting in the fish targets in the fish gathering area being unable to flow for a long time, consuming a lot of physical energy, leaving the area, and even getting injured and dying.

[0083] To this end, the present application provides a method for controlling fish fence equipment, by obtaining multiple pieces of fish passing information at the entrance position collected by a fish monitoring sensor set at the entrance position of a first fish collecting area in a fish passage, determining statistical information of fish entering the fish collecting area, if the fish statistical information reaches a preset control trigger condition of the fish driving fence equipment corresponding to the fish collecting area, then controlling the fish driving fence equipment to advance in the fish driving area, driving the fish to the second fish collecting area at the end of the fish passage, controlling the fish lifting machine to lift the fish collecting box in the second fish collecting area to a preset height, and then transferring the fish to the fish transport device to be transported to the upstream of the dam by a vehicle or a rail cable car for release, so that the fish can pass through the dam smoothly and steadily, thereby improving the efficiency of fish driving and reducing labor costs.

Figure 1 As shown, the first fish collecting area is arranged at the entrance of the fish passage, an underwater observation box is arranged at the entrance of the first fish collecting area, a fish monitoring sensor (not shown in the figure) is arranged in the underwater observation box, a fish guide net and a guide baffle are arranged in the fish passage outside the first fish collecting area, and the underwater observation box is connected to the guide baffle through the fish guide net; the second fish collecting area is arranged at the end of the fish passage, a fish collecting pond and a fish collecting box are arranged in the second fish collecting area, the fish collecting box is used to lift the fish in the fish collecting pond to a preset height, the fish driving area is arranged above the fish passage, a fish driving fence control device moves in the fish driving area, and a fish driving fence net is connected to the front end of the fish driving fence control device.

[0086] Step 201: Acquire multiple pieces of fish passing information at the entrance position collected by a fish monitoring sensor set at the entrance position of the first fish collecting area in the fish passage.

[0087] Among them, each piece of fish passing information is used to indicate that a target fish has passed through the first fish gathering area, and the first fish gathering area is set in the fish passing channel. The fish passing channel is set in the downstream waters so that fish can move in the dam. The first fish gathering area is provided with an underwater observation box. The fish passing channel outside the first fish gathering area is also provided with a fish guide net and a guide baffle. The fish guide net and the guide baffle can ensure that all fish in the fish passing channel can enter the fish passing channel through the first fish gathering area. A fish monitoring sensor is provided in the underwater observation box. The fish monitoring sensor is used to collect multiple pieces of imported fish passing information. The fish monitoring sensor is a fish intelligent identification monitoring sensor. The fish intelligent identification monitoring sensor can be an acoustic sensor, an electromagnetic sensor, an optical sensor or other sensors, and the embodiment of the present application does not limit this. The fish monitoring sensor uses the collected sensor data to obtain multiple pieces of fish passing information through real-time intelligent identification by a deep learning neural network algorithm.

[0088] Optionally, by acquiring sensor data collected by a fish monitoring sensor installed at the entrance position of the first fish gathering area in the fish passage, and using a deep learning neural network algorithm to intelligently identify the sensor data in real time, multiple fish passing information at the entrance position can be obtained, and each piece of fish passing information indicates that a target fish has passed through the first fish gathering area.

[0089] Step 202: Determine statistical information of fish species that have entered the first fish gathering area based on the plurality of fish passing information.

[0090] Among them, the fish statistical information can be information such as the number of fish, fish species, and fish body length. The embodiment of the present application does not limit this. The fish statistical information is used to indicate the overall information of multiple fish in the first fish gathering area.

[0091] Optionally, fish statistics information of multiple fish that have arrived at the first fish gathering area is determined based on multiple pieces of fish passing information.

[0092] Step 203: Determine, based on the fish statistics information, whether a preset control trigger condition of the fish driving fence equipment corresponding to the first fish gathering area is met.

[0093] Among them, the preset control trigger conditions can be information such as the number of fish, fish species, and fish body length, which is not limited in this embodiment of the present application.

[0094] Optionally, the content related to the preset control trigger condition in the fish statistical information is compared with the preset control trigger condition of the fish fence equipment corresponding to the first fish gathering area. If the fish statistical information is equal to the preset control trigger condition, it is determined that the preset control trigger condition of the fish fence equipment corresponding to the first fish gathering area is met.

[0095] If yes, execute step 204.

[0096] Step 204, controlling the fish driving fence equipment to move forward in the fish driving area to drive the fish driving fence net to move to the end of the fish passage.

[0097] The fish-driving fence device is used to drive the fish in the first fish-collecting area to the second fish-collecting area at the end of the fish passage. The fish-driving fence device is controlled to move forward or backward by driving a motor through a control unit, and the control unit may be a programmable logic controller (PLC).

[0098] Optionally, when the fish statistics information reaches the preset control trigger condition of the fish driving fence device corresponding to the first fish gathering area, information is sent to the control unit so that the control unit drives the motor to control the fish driving fence device to move forward in the fish driving area through the motor, so as to drive the fish driving fence net to the end of the fish passage, so as to drive the fish in the first fish gathering area to the second fish gathering area at the end of the fish passage.

[0099] Step 205: Control the fish elevator to lift the fish collecting box in the second fish collecting area to a preset height.

[0100] Optionally, when the fish-driving fence equipment drives the fish in the first fish-collecting area to the second fish-collecting area at the end of the fish passage, the fish lift is controlled to lift the fish-collecting box in the second fish-collecting area, so that the target fish in the second fish-collecting area are lifted to a preset height through the fish-collecting box, thereby transporting the target fish from downstream to upstream.

[0101] An embodiment of the present application provides a method for controlling a fish driving fence device, by acquiring multiple pieces of fish passing information at an entrance position collected by a fish monitoring sensor arranged at an entrance position of a first fish collecting area in a fish passage, determining statistical information of fish entering the first fish collecting area based on the multiple pieces of fish passing information, and when the fish statistical information reaches a preset control trigger condition of the fish driving fence device corresponding to the first fish collecting area, controlling the fish driving fence device to advance in the fish driving area to drive the fish driving fence net to move to the end of the fish passage, and driving the fish in the first fish collecting area to the second fish collecting area at the end of the fish passage, thereby controlling the fish lift to lift the fish collecting box in the second fish collecting area to a preset height. The present application controls the fish driving fence device to drive the fish from the first fish collecting area through the fish passage to the end of the second fish collecting area for comparison when the number of fish entering the first fish collecting area reaches the preset control trigger condition of the fish driving fence device corresponding to the first fish collecting area, thereby driving the fish. This ensures that when the fish driving fence device is working, the number of target fish in the first fish collecting area is relatively moderate, avoiding the inefficient state of extremely small number of fish driven at a single time or damage caused by a large number of fish, and can maximize the operating efficiency of fish driving. The fish lift is controlled to lift the fish collecting box in the second fish collecting area to a preset height, thereby improving the efficiency of fish driving, saving labor costs, and reducing the waste of electricity resources and the loss of related equipment.

[0102] On the basis of the above-mentioned embodiment, each piece of fish passing information includes: fish species and fish passing time; the present application also provides a process for determining fish statistical information in the first fish driving fence device control method, Figure 3 A schematic diagram of a process for determining fish statistics information in a first method for controlling a fish-driving fence device provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, in the above step 202, according to the multiple pieces of fish passing information, the statistical information of fish entering the first fish gathering area is determined, including:

[0103] Step 301: Determine the fish passing information of the target fish according to the fish species in the multiple fish passing information.

[0106] Step 302: Determine fish statistics information of target fish that enter the first fish gathering area within a preset time period according to the fish passing time in the fish passing information of the target fish.

[0107] Among them, the fish passing time is used to indicate the time when the tail fish passes through the fish monitoring sensor; the preset time is determined according to the current demand for driving fish. When the number of fish entering is large, the preset time period can be set to a shorter time, and when the number of fish entering is small, the preset time period can be set to a longer time. For example, the preset time can be one minute, and the embodiment of the present application does not limit this.

[0108] Optionally, the time when the target fish passes through the fish monitoring sensor is determined according to the fish passing time in the fish passing information of the target fish, thereby determining the fish statistics information of the target fish entering the first fish gathering area within a preset time period.

[0126] Step 601: Determine whether the target fish passing length information reaches a preset fish passing length threshold.

[0127] Among them, the preset fish passing length threshold is determined according to the target fish.

The embodiment of the present application does not limit the preset fish passing length threshold, and the specific length is determined according to actual conditions. In this application, 2000mm is taken as an example.

[0128] For example, the target fish passing length information is compared with 2000 mm to determine whether the target fish passing length information reaches 2000 mm. If so, the target fish passing length information reaches the preset fish passing length threshold.

[0129] Step 602: Determine whether the target fish passing quantity information reaches a preset fish passing quantity threshold.

[0141] Optionally, after the control unit receives the start signal, it obtains the detection distance between the fish fence device and the retreat limit device in the fish driving area collected by the distance sensor on the fish fence device, and rotates the fault signals of all relevant sensors and inverters at a preset time interval. If a fault is found, the operation is stopped and an error is reported. The preset time can be 0.2 seconds and the embodiment of the present application does not impose any limitation on this.

[0148] Optionally, if the mapping data block corresponding to the far-end distance limit signal of the distance sensor and the status information of the mapping data block corresponding to the retreat limit device are available, it can be determined whether the fish-driving fence device is in the preset initial position. If the mapping data block corresponding to the trigger signal of the retreat limit device is "1", the fish-driving fence device is in the preset initial position.

[0149] Step 703: If the fish fence device is not at the preset initial position, control the fish fence device to retreat to the preset initial position.

[0150] Optionally, if the mapping data block corresponding to the distance signal of the backward limit device of the distance sensor is "0" and the mapping data block corresponding to the backward limit device trigger signal is "0", it is judged that the fish fence equipment is not in the preset initial position, and the control unit is controlled to control the frequency converter through the control unit, and the frequency converter sends a reverse signal to drive the motor backward so that the fish fence equipment retreats to the initial position.

[0154] In the embodiment of the present application, the position of the fish driving fence device is determined by a distance sensor and a backward limit device, so that when the fish driving fence device moves forward from an initial position, all target fish in the first fish gathering area are driven to the second fish gathering area, thereby improving the fish driving efficiency.

[0155] Based on the above embodiments, the present application also provides a process of lifting a fish collecting box in a method for controlling a fish fence device.

The forward limit device is set at the end of the fish passage at a position 1 / 2 the length of the fish driving fence device from the second fish gathering area. The forward limit device is used to determine whether the fish driving fence has reached the second fish gathering area. The forward limit device can be a limit sensor or other equipment, and the embodiment of the present application does not limit this.
