Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering construction equipment and method. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are of great significance for ensuring the rational use of water resources, flood control and drought relief, and improving the ecological environment. They encompass flood control projects, farmland irrigation projects, hydropower projects, and water supply and drainage projects, greatly enhancing the comprehensive benefits of the Yangtze River Basin. The construction of water conservancy projects requires comprehensive consideration of geographical, climatic and hydrological natural conditions, as well as economic and social factors. They must undergo scientific planning, design and construction. For example, the Dujiangyan Irrigation System has been in operation for more than two thousand years and still plays a role in irrigation and flood control. It reflects the wisdom and technical level of ancient water conservancy projects and provides valuable lessons for modern water conservancy construction, promoting the continuous development of water conservancy in a more efficient and sustainable direction.

[0003] Construction equipment is crucial for ensuring the smooth progress of water conservancy projects, encompassing excavation, transportation, pouring, and foundation treatment. Excavation equipment, such as excavators and loaders, efficiently completes earthwork excavation and adapts to various geological conditions. Transportation equipment, including dump trucks and belt conveyors, transports materials from the mining area or processing plant to the construction site, ensuring a continuous supply of materials. However, dredging is extremely important during construction, as large amounts of silt can cause blockages in construction sections. With technological advancements, dredging mechanisms are specialized devices used to remove silt from the bottom of rivers, canals, and reservoirs. Their core function is to remove deposited mud, sand, and debris from the bottom of the water body through mechanical and hydraulic action, restoring the water body's flood control, irrigation, and navigation functions. Common dredging mechanisms are mechanical dredging equipment, which directly removes silt through mechanical cutting and grabbing. They are suitable for waters with thick silt and many impurities. However, this type of dredging mechanism cannot be stably fixed to the ground, causing the wheels to slip during the dredging process, thus affecting the efficiency of dredging.

[0028] A construction method based on water conservancy engineering construction equipment, specifically including the following steps;

[0029] Step 1: First, after the equipment is driven to the designated position, start the cylinder. At this time, the cylinder will push the side push plate to move inward, and the side push plate will squeeze the rotating rod inward.

[0030] Step 2: The rotating rod will stretch up and down, thus increasing the distance between the upper and lower top plates. The lower top plate will move downward against the gripping floor until the fixing pile hits the ground, lifting the equipment. At this time, springs 2 and 1 will be stretched and deformed, allowing the robotic arm and bucket to move and perform digging and dredging operations. This achieves more stable support for the equipment and prevents it from moving during operation.

[0031] Step 3: When the robotic arm and bucket work together to dredge the silt, the bucket loads the excavated silt into the collection box. Once the collection box is full, unscrew the nut. The nut will then separate from the bolt, and the bolt will separate from the fixing plate and connecting plate. At this point, the connecting plate can be pulled out from the square groove, allowing the silt in the connecting plate to be processed. The same process applies when reinstalling: insert the connecting plate along the square groove and screw in the bolt and nut. This integrates the collection device with the equipment, enabling the temporary collection of silt and waste.

[0032] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects:

[0033] 1. In this invention, when the equipment is driven to the designated position, the cylinder is activated. At this time, the cylinder will push the side push plate to move inward. The side push plate will then squeeze the rotating rod inward, and the rotating rod will stretch up and down. This stretches the distance between the upper and lower top plates. Then the lower top plate will move downward against the gripping floor until the fixing pile is stuck to the ground, lifting the equipment. This achieves a more stable fixation and support for the equipment, preventing it from moving during operation.

[0034] 2. In this invention, when the robotic arm and the bucket work together to dredge silt, the bucket loads the excavated silt into the storage box. When the storage box is full, the nut is unscrewed. At this time, the nut is removed from the bolt, and then the bolt will be removed from the fixing plate and the connecting plate. This realizes that the storage device and the equipment are integrated, which can temporarily store silt and garbage. Attached Figure Description

[0055] like Figure 6 As shown, the driver's cab includes a human-machine interface, a processor unit, a communication module, a clock unit, a memory module, and a power supply module.

[0057] This invention uses Xilinx's Spartan6 series FPGA as the core controller, realizing functions such as data acquisition control, data buffering, data processing, data storage, data transmission, and synchronous clock control. It features high precision, high speed, high reliability, strong real-time performance, and low cost. This invention is a 16-channel real-time high-speed and high-precision synchronous data acquisition system with FPGA as the main processor. The sampling frequency in actual monitoring projects is 200kHz. By using FPGA to reasonably control and coordinate the data flow between various modules, the system can achieve the real-time, synchronous, and high-speed acquisition functions required by the system.

[0058] The system control core uses the Xilinx Spartan 6 series chip XC6SLX45. The sixth-generation Spartan 6 FPGA is based on the widely recognized low-power 45nm, 9-metal copper layer, dual-gate oxide process technology, providing advanced power management technology, 150,000 logic cells, hard-core DRAM memory, and various IPs. It is one of Xlinx's most widely used and technologically mature FPGA series. The FPGA main control module primarily handles camera configuration and video data acquisition, DDR3-SDRAM data storage and retrieval, and HDMI interface chip configuration and video data transmission. Its hardware circuitry also includes power supply circuitry, reset circuitry, crystal oscillator circuitry, download circuitry, and SPI Flash configuration circuitry.

[0059] To address the caching issue of high-speed, high-capacity video data, this system uses the Micron MT41J256M16HA-125 4Gbit DDR3-SDRAM memory chip as the cache medium. A0-A14 are the address bus, B0-B3 are the Bank addresses; the FPGA controls the data storage location in the DDR3-SDRAM by controlling the address bus and Bank addresses. D0-D15 are the data bus, connected in parallel with the FPGA. CLK-N and CLK-P are differential clock input ports; the clock frequency in this system is set to 312.5MHz. The FPGA controls the read and write operations of the DDR3-SDRAM through the Column Address Select (CAS), Row Address Select (RAS), and Write Enable (WE) signals. Performance optimization is achieved by controlling the ODT to enable on-chip resistors and prevent data line interruption reflections. DQS is the synchronization signal between the DDR3-SDRAM and the controller; it is bidirectional, issued by the controller when writing data and by the memory when reading data. DM is the data mask signal. Since only Bank1 and Bank3 of the Spartan6 series FPGA have MCB hard cores, in this system, Bank3 of the FPGA is connected to DDR3-SDRAM with a port voltage standard of 1.5V. In the FPGA UCF, the IO standard needs to be set to SSTL15_II.

[0060] After the system powers on, it waits for the FPGA to complete initialization and enters a connection-waiting state. When relevant command parameters are input externally, the FPGA receives and parses the commands. First, it controls the internal selection switch of the system to operate, connecting the selected device signal to the acquisition system. Then, it sends control information to the device under test (DUT), while the acquisition system monitors the power supply status of the DUT in real time. Subsequently, the acquired data is buffered in the FPGA's internal Random Access Memory (RAM) for processing. Finally, the acquired data is transmitted back to an external monitor for real-time display via the FPGA's on-chip First-In-First-Out (FIFO) queue. The data is then processed and stored according to appropriate rules to generate a test data report.

[0061] Storage Circuit: After data acquisition, the sampled data from the corresponding channel is sent to the monitor for real-time display and stored in the Flash memory, awaiting read commands from the external controller. This system uses STMicroelectronics' S25FL128 PFL flash memory for real-time storage. This chip has a storage capacity of 128 Mbit and communicates with the external controller via an SPI interface with a maximum clock frequency of 104 MHz. This chip features simple design, stable data storage, and low cost, making it widely applicable.

[0062] To address the limitations of traditional data acquisition and processing systems in effectively achieving synchronization and real-time performance during data transmission and storage, this system employs an FPGA-controlled AD7609 to read data during conversion, enabling a sampling rate of 200kHz. By effectively utilizing the FPGA's internal resources and implementing a ping-pong data buffering mechanism, real-time data transmission and Flash storage are achieved, enhancing the reliability, efficiency, and stability of data transmission and storage. This significantly leverages the FPGA's high-speed parallel data processing capabilities and timing constraints.

[0066] This invention relates to an RF switch circuit that can better meet the requirements of large voltage swing operation while ensuring insertion loss and isolation. It improves upon traditional stacking technology, reduces uneven voltage distribution, significantly improves branch voltage handling capability, and enhances branch voltage tolerance, thereby better serving antenna tuning and ensuring normal operation even under antenna mismatch conditions. The RF switch section adopts a series-parallel structure, with complementary control signals for the two branches. When the series branch is on, it is equivalent to a small resistance, and when the parallel branch is off, it is equivalent to a capacitor and a resistor in parallel.

[0067] The wireless radio frequency chip used is the nRF905 wireless transceiver chip. The nRF905 is a long-range wireless transceiver chip with multiple transmitting points, long transmission distance, and strong anti-interference capabilities. It operates in three ISM bands: 433 / 868 / 915MHz, with a switching time between transmit and receive modes of less than 650µs. Ports such as TRX_CE, PWR_UP, TXEN, CSN, SCK, MISO, and MOSI are connected to the microcontroller. CSN, SCK, MISO, and MOSI form an SPI interface. When transmitting data, the nRF905 is set to transmit mode. The microcontroller writes the receiver address and valid data into the chip's buffer via the SPI interface, then generates a CRC and preamble using the TRX_CE level, and transmits the data. When receiving data, the nRF905 is set to receive mode, waiting for data arrival. Upon receiving the preamble, valid address, and CRC, the data is stored in a register, generating an interrupt that prompts the microcontroller to read it.

[0068] Working principle: First, after the equipment is driven to the designated position, cylinder 202 is activated. At this time, cylinder 202 will push the side push plate 203 to move inward. The side push plate 203 will then press the rotating rod 204 inward, and the rotating rod 204 will stretch up and down. This stretches the distance between the upper top plate 201 and the lower top plate 206. Then, the lower top plate 206 will move downward against the gripping floor 2071 until the fixing pile 2072 is stuck to the ground, lifting the equipment. At this time, spring 2074 and spring 205 will be stretched and deformed, allowing the robotic arm 601 and bucket 602 to perform digging and dredging operations. This achieves more stable fixed support for the equipment and prevents it from moving during operation.

[0069] When the robotic arm 601 and the bucket 602 work together to dredge silt, the bucket 602 loads the excavated silt into the collection box 3052. Once the collection box 3052 is full, the nut 304 is unscrewed, causing the nut 304 to separate from the bolt 303. The bolt 303 then separates from the fixing plate 301 and the connecting plate 3051. The connecting plate 3051 can then be pulled out of the square groove 302, allowing the silt in the connecting plate 3051 to be processed. The same procedure applies when reinstalling: the connecting plate 3051 is inserted along the square groove 302, and the bolt 303 and nut 304 are screwed in. This integrates the collection device with the equipment, enabling the temporary storage of silt and waste.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
