Description

Technical Field

[0001] This disclosure relates to the field of material transportation technology, and more specifically, to a construction site material transportation system. Background Technology

[0002] With the rapid development of my country's economic construction and power grid construction, the construction environment of transmission lines has become increasingly complex. Transmission line projects are generally long and have large spans, and the lines are often set up in various terrains with different degrees of remoteness, which makes the requirements for line construction constantly increasing.

[0003] Due to the varying remoteness and terrain of power transmission line projects, the construction environment also varies. In addition, each power transmission line requires a large amount of construction materials. How to quickly transport construction materials from the loading area to the vicinity of the power transmission line under different construction environments in order to improve the construction speed of power transmission line projects has become a problem that needs to be solved. Utility Model Content

[0004] This application discloses a construction site material transportation system that can quickly transport construction materials from the loading area to the vicinity of power transmission lines under different environments, thereby improving the construction speed of power transmission line projects.

[0005] In some embodiments, this disclosure relates to a construction site material transportation system, the construction site material transportation system comprising: a central controller; a loading device communicatively connected to the central controller; and a transport vehicle communicatively connected to the central controller. The transport vehicle includes a hopper, a weight sensor, a level gauge, and a temperature control device. The weight sensor is located at the bottom of the hopper. After the central controller sends a loading command to control the loading device to load construction materials into the hopper, the weight sensor measures the weight of the construction materials in the hopper and sends the weight value to the central controller. The level gauge detects the height of the construction materials in the hopper and sends the height to the central controller. The temperature control device is located on the periphery of the outer wall of the hopper and is used to maintain a constant temperature of the construction materials in the hopper.

[0006] The construction material transportation system of this application embodiment can transport construction materials from the loading area to a highway point near the power transmission line by having the central controller control the loading equipment to load the construction materials into the hopper of the transport vehicle. During the loading process, the weight sensor installed in the transport vehicle can measure the weight of the construction materials loaded into the hopper by the loading equipment, the level gauge can detect the height of the construction materials, and the constant temperature device can ensure that the temperature of the construction materials is constant. Then, the transport vehicle automatically delivers the construction materials with constant temperature to the highway point, completing the automated transportation of construction materials, thereby reducing the cost of manual transportation and management.

[0007] In some embodiments, the temperature control device includes an insulation layer, a temperature controller, and multiple temperature sensors. The insulation layer covers the outer wall of the silo, and the multiple temperature sensors are equally spaced between the insulation layer and the silo. The temperature controller is located between any two adjacent temperature controllers.

[0008] In some embodiments, the silo includes a silo body, the silo body is fixedly connected to the silo bottom, a support part is provided in the middle of the silo bottom, the weight sensor is provided in the support part, a vibrator is provided on the outer wall of the silo body near one end of the silo bottom, and the central controller is also used to send a cleaning command to the vibrator so that the vibrator drives the silo to vibrate to clean the construction materials remaining in the silo.

[0009] In some embodiments, a blowing device is provided on the outer wall of the bin body at the end away from the bottom of the bin, and the central controller is also used to send a cleaning command to the blowing device so that the blowing device blows the inner wall of the bin.

[0010] In some embodiments, the blowing device includes a plurality of nozzles, which are evenly distributed on the outer wall of the main body of the silo away from the bottom of the silo, and the angle between the spray direction of each nozzle and the bottom of the silo is an acute angle.

[0011] In some embodiments, the hopper further includes a hopper cover, and the outer wall of the hopper is provided with an electromagnetic lock and a card reader. The electromagnetic lock is used to close the hopper cover and lock the opening of the hopper body. The central controller is also used to control the electromagnetic lock to unlock the hopper body and the hopper cover after receiving a card reading success message from the card reader.

[0012] In some embodiments, the main body of the silo is provided with a maximum material line, and the height between the level gauge and the bottom of the silo is not less than the sum of the height between the maximum material line and the bottom of the silo, the blind zone height of the level gauge, and the preset safety space height.

[0013] In some embodiments, the transport vehicle further includes a frame, the outer side of which is provided with a unique vehicle tag. The hopper is vertically connected to the frame. The loading device includes a tag reader and a loading device, the tag reader being located at one end of the loading device. The central controller is used to send material transport instructions to the loading device to control the tag reader to scan and identify the vehicle tag and pass through, and then control the loading device to load the construction materials in the loading area into the hopper, so that the transport vehicle transports the construction materials to the target location according to a preset planned path.

[0014] In some embodiments, the construction site material transportation system further includes an online monitoring instrument and a dust removal system. Both the online monitoring instrument and the dust removal system are communicatively connected to the central controller. The online monitoring instrument and the dust removal system are located within the loading area and along the road of the preset planned path. The online monitoring instrument is used to monitor the dust levels in the loading area and along the road and send the dust levels to the central controller. The central controller is also used to control the dust removal system to start spraying to reduce dust when it detects that the dust levels are greater than a preset dust threshold.

[0015] In some embodiments, the loading device includes a loading bracket, a loading assembly, and a loading base. One end of the loading bracket is rotatably connected to the loading base, and the other end is detachably connected to the loading assembly. The loading assembly is used to load the construction materials into the silo.

[0016] The construction material transportation system of this application embodiment wraps the outer wall of the silo with an insulation layer, and installs a temperature controller and temperature sensor between the insulation layer and the silo to ensure a constant temperature of the construction materials inside the silo, preventing extreme temperatures from affecting the condition of the construction materials and delaying the project progress. Vibrators and spray nozzles are installed to improve the unloading rate of construction materials; dual verification through electromagnetic locks and code reading prevents management loopholes such as unauthorized unloading during transportation, achieving closed-loop verification of the transportation task; construction materials are loaded onto the transport vehicle only after the tag reader identifies the vehicle code of the transport vehicle, avoiding the problem of construction materials being loaded into the wrong transport vehicle. Simultaneously, an online monitoring instrument and dust removal system are also installed. If the dust level detected during transportation does not meet the standard, the dust removal system sprays and removes dust, ensuring that the construction project meets environmental protection requirements.

[0031] With the rapid development of my country's economic construction and power grid construction, the construction environment of transmission lines has become increasingly complex. Transmission line projects are generally long and have large spans, and the lines are often set up in various terrains with different degrees of remoteness, which makes the requirements for line construction constantly increasing.

[0032] Due to the varying remoteness and terrain of power transmission line projects, the construction environments differ significantly. Furthermore, each transmission line requires substantial amounts of construction materials. Since these lines are typically located in mountainous or hilly areas where vehicles cannot directly traverse, construction materials must be transported from the loading area to a nearby roadway, and then manually transported to the transmission line. Therefore, finding a way to rapidly transport construction materials from the loading area to the vicinity of the transmission line under these diverse conditions, thereby accelerating construction, has become a critical issue that needs to be addressed.

[0033] To address the aforementioned issues, this application provides a construction site material transportation system. This system can be used to quickly transport construction materials from the loading area to the vicinity of the power transmission line during the construction of a power transmission line project, based on the different terrain and environment of the power transmission line, thereby improving the construction speed of the power transmission line project.

[0034] It should be noted that this application does not limit the specific application scenarios of the construction site material transportation system. Depending on the actual situation, the construction site material transportation system can also be applied to other application scenarios besides those mentioned above.

[0035] Please refer to Figure 1 The construction site material transportation system includes a central controller 1, transport vehicles 2, and loading equipment 3. Both transport vehicles 2 and loading equipment 3 are communicatively connected to the central controller 1. In this embodiment, the central controller 1 can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor, a single-chip microcomputer, or any conventional processor.

[0036] For specific details, please refer to... Figure 2 and Figure 3 As shown, the transport vehicle 2 includes a hopper 21, a weight sensor 22, a level gauge 23, and a temperature control device 24. The weight sensor 22 is located at the bottom 211 of the hopper 21. After the central controller 1 sends a loading command to control the loading equipment 3 to load construction materials into the hopper 21, the weight sensor 22 measures the weight of the construction materials in the hopper 21 and sends the weight value to the central controller 1. In this example, the weight sensor 22 can be a resistance strain gauge weight sensor, a capacitive weight sensor, a piezoelectric weight sensor, an electromagnetic force balance weight sensor, or a piezoresistive weight sensor. This application does not limit the specific type of weight sensor.

[0037] A level gauge 23 is located on the inner wall of the silo 21. The level gauge 23 is used to detect the height of the construction materials inside the silo 21 and sends the height information to the central controller 1. A temperature control device 24 is located on the periphery of the outer wall of the silo 21. The temperature control device 24 is used to maintain a constant temperature of the construction materials inside the silo 21. In this embodiment, the level gauge 23 can be a laser level gauge, an ultrasonic level gauge, or a radar level gauge; this application does not limit the specific type of level gauge 23. The level gauge 23 is installed to prevent excessive construction materials from being loaded into the silo 21 by the loading equipment 3, thus avoiding leakage and waste of materials from the transport vehicle 2.

[0038] Because power transmission line projects require a variety of construction materials, such as iron towers, concrete poles, steel pipe poles, concrete, rocks, conductors, insulators, cement, and gravel, some of these materials are prone to deformation at high temperatures or solidification at low temperatures, affecting the construction progress. Therefore, a temperature control device 24 is installed on the outer periphery of the material silo 21 to ensure that the temperature of the construction materials remains constant during the transportation of the materials from the loading area to the vicinity of the power transmission line, thereby avoiding any impact on the construction progress.

[0039] When the absolute difference between the height of the construction material in the hopper 21, as indicated by the level gauge 23, and a preset height threshold is less than a preset height difference, the central controller 1 controls the loading device 3 to stop loading construction material into the hopper 21 to prevent leakage of construction material. Similarly, when the absolute difference between the weight of the construction material in the hopper 21, as indicated by the weight sensor 22, and a preset weight threshold is less than a preset weight difference, the central controller 1 also controls the loading device 3 to stop loading construction material into the hopper 21 to prevent excessive construction material from damaging the hopper 21. The preset height threshold and preset height difference are set according to actual loading requirements, and this application does not limit their specific values. Similarly, the preset weight threshold and preset weight difference are also set according to actual loading requirements, and this application does not limit their specific values.

[0040] In this embodiment, the transport vehicle 2 may further include a vehicle controller 25, which is communicatively connected to the central controller 1, a weight sensor 22, a level gauge 23, and a temperature control device 24. The vehicle controller 25 is used to control the start and stop of the transport vehicle 2. The weight sensor 22 transmits the weight value of the construction materials in the hopper 21 to the central controller 1 via the vehicle controller 25, so that staff can promptly check the weight of the construction materials transported by the transport vehicle 2.

[0041] Similarly, the level gauge 23 transmits the height of the construction materials in the silo 21 to the central controller 1 via the vehicle controller 25. The temperature control device 24 transmits the temperature value of the construction materials in the silo 21 to the central controller 1 via the vehicle controller 25. The central controller 1 sends a temperature control command to the vehicle controller, so that the vehicle controller 25 controls the operation of the temperature control device 24 to maintain a constant temperature of the construction materials in the silo 21. The central controller 1 can also send commands to the transport vehicle 2 to control its operation.

[0042] In this embodiment of the construction material transportation system, when it is necessary to transport construction materials from the loading area to a road point near the power transmission line, the central controller 1 can control the loading equipment 3 to load the construction materials into the hopper 21 of the transport vehicle 2. During the loading process, the weight sensor 22 installed in the transport vehicle 2 can measure the weight of the construction materials loaded into the hopper 21 by the loading equipment 3, the level gauge 23 can detect the height of the construction materials, and the constant temperature device 24 can ensure that the temperature of the construction materials is constant. Then, the transport vehicle 2 automatically transports the construction materials with constant temperature to the road point, completing the automated transportation of construction materials, thereby reducing the cost of manual transportation and management.

[0043] In some embodiments, please refer to Figure 4The temperature control device 24 includes an insulation layer 241, a temperature controller 242, and multiple temperature sensors 243. The outer wall of the silo 21 is wrapped with the insulation layer 241. The insulation layer 241 is used to maintain a constant temperature of the construction materials inside the silo 21, preventing the construction materials from being affected by high or low temperatures in the external environment. Multiple temperature sensors 243 are equally spaced between the insulation layer 241 and the silo 21, and the temperature controller 242 is located between any two adjacent temperature controllers 242. The temperature controller 242 can heat the silo 21 when the ambient temperature of the transport vehicle 2 is extremely low, or cool the silo 21 when the ambient temperature of the transport vehicle 2 is extremely low, in order to maintain a constant temperature of the construction materials inside the silo 21. The temperature sensors 243 are used to measure the temperature of the construction materials inside the silo 21.

[0044] In this embodiment, the temperature sensor 243 can be a thermocouple sensor or an infrared temperature sensor 243, and the temperature controller 242 can be a switch-type temperature controller or a fuzzy control temperature controller. This application does not limit the specific types of the temperature sensor 243 and the temperature controller 242, as long as the temperature controller 242 can regulate the temperature of the construction material in the silo 21 and the temperature sensor 243 can measure the temperature of the construction material in the silo 21.

[0045] In this embodiment, there are six temperature sensors 243, and two temperature controllers 242 are provided on opposite sides of the hopper 21. In other embodiments, the number of temperature sensors 243 may be four, eight, or nine, and the number of temperature controllers 242 may be one, three, or four. This application does not limit the specific number of temperature controllers 242 and temperature sensors 243.

[0046] In some embodiments, the silo 21 includes a silo body 212, which is fixedly connected to a silo bottom 211. An opening is formed at one end of the silo body 212 away from the silo bottom 211, through which the loading device 3 loads construction materials into the silo body 212. In this embodiment, an insulation layer 241 covers the outer wall of the silo body 212.

[0047] Specifically, a support part 213 is provided in the middle of the bottom 211 of the silo, and a weight sensor 22 is provided on the support part 213. A vibrator 26 is provided on the outer wall of the silo body 212 near the bottom 211. The central controller 1 is also used to send a cleaning command to the vibrator 26 so that the vibrator 26 drives the silo 21 to vibrate and clean the construction materials remaining in the silo 21. In this embodiment, the silo 21 is a cuboid. In other embodiments, the silo 21 can also be a frustum or a truncated cone. This application does not limit the specific shape of the silo 21. By installing the vibrator 26 on the outer wall of the silo body 212 near the bottom 211, the material accumulated and adhering to the discharge port can be effectively cleaned during unloading.

[0048] Furthermore, a blowing device 27 is provided on the outer wall of the bin body 212 away from the bin bottom 211. The central controller 1 is also used to send a cleaning command to the blowing device 27 so that the blowing device 27 blows the inner wall of the bin 21.

[0049] In this embodiment, the blowing device 27 may include a nozzle 271, a solenoid valve (not shown in the figure), and an air tank (not shown in the figure). One end of the air tank is connected to the solenoid valve via a pipeline, and the other end is connected to the nozzle 271 via a pipeline. The solenoid valve is used to control the opening and closing of the air tank to activate the blowing function of the nozzle 271. The solenoid valve is electrically connected to the vehicle controller 25, which controls the opening or closing of the solenoid valve (it can be understood that if the transport vehicle 2 does not have a vehicle controller 25, the central controller 1 can also directly control the opening or closing of the solenoid valve).

[0050] That is, when the central controller 1 sends a material clearing command, the vehicle controller 25 controls the solenoid valve to open, and compressed air is rapidly ejected from the air tank through the pipeline and from the nozzle 271 at high speed. These airflows act like "air knives," directly impacting the inner wall of the hopper 21 and completely blowing off the loosened residual material from the vibrator 26. The effect is particularly significant for dry, dusty materials.

[0051] Specifically, the number of nozzles 271 can be one or more. When there are multiple nozzles 271, they are evenly distributed on the inner wall of the bin body 212 away from the bin bottom 211, and the angle between the spray direction of each nozzle 271 and the bin bottom 211 is an acute angle. For example, the angle between the spray direction and the bin bottom 211 can be 30°, 45°, 55° or 60°. This application does not limit the specific value of the angle between the spray direction and the bin bottom 211, as long as the spray direction of the nozzle 271 is to the inside of the bin 21.

[0052] Figure 3 The nozzle 271 shown can be rotatably connected to the inner wall of the main body 212 of the chamber. By controlling the rotation of the nozzle 271, the angle between the spray direction and the bottom of the chamber 211 can be adjusted to be an acute angle.

[0053] In other embodiments, multiple nozzles 271 may also be disposed on the inner wall of each side of the silo body 212. Each nozzle 271 can blow on the inner wall of its own side, or each nozzle 271 can blow on the inner wall of the opposite side. By disposing of nozzles 271 on the outer wall of each side of the silo body 212, the blowing range of the blowing device 27 can cover the inner wall of the silo 21 as much as possible, resulting in a better blowing effect.

[0054] In some embodiments, please refer to Figure 5The hopper 21 also includes a hopper cover 214. The outer wall of the hopper 21 is also provided with an electromagnetic lock 215 and a card reader 216. The electromagnetic lock 215 is used to close the hopper cover 214 and lock the hopper opening of the hopper body 212. The central controller 1 is also used to control the electromagnetic lock 215 to unlock the hopper body 212 and the hopper cover 214 after receiving the card reading success information from the card reader 216.

[0055] In this embodiment, the card reader 216 is located on the outer wall of the main body 212 of the warehouse. Both the electromagnetic lock 215 and the card reader 216 are electrically connected to the vehicle controller 25. The card reader 216 can be an RFID card reader. After the loading equipment 3 completes the loading of construction materials, the central controller 1 sends a locking command to the vehicle controller 25, which then activates the electromagnetic lock 215 to lock the warehouse cover 214 and the main body 212. The transport vehicle 2 then transports the construction materials to the highway point. At the highway point, the staff holds the RFID card to the RFID card reader. After the RFID card reader reads the RFID card information, it sends a card reading success message to the vehicle controller 25. The vehicle controller 25 then sends this message to the central controller 1, which sends an unlocking command to the vehicle controller 25. The vehicle controller 25 then activates the electromagnetic lock 215 to unlock the warehouse cover 214 and the main body 212. Workers can perform the unloading process. Thus, the safety of loading and unloading construction materials is ensured by the dual verification of electromagnetic lock 215 and card reader, and the loss of construction materials is also avoided.

[0056] In other embodiments, the card reader 216 may be other devices besides an RFID card reader, and this application does not limit the type of card reader 216.

[0057] It should be noted that, in order not to affect the closing of the bin cover 214 onto the bin body 212, the distance between the nozzle 271 and the end point of the bin body 212 furthest from the bin bottom 211 is greater than the height of the nozzle 271. Thus, no matter how the nozzle 271 rotates, it will not affect the closing of the bin cover 214 onto the bin body 212.

[0058] In some embodiments, the silo body 212 is provided with a maximum material line H. The purpose of setting the maximum material line H is to measure the highest position of construction materials that the silo 21 can hold. Since the level gauge 23 has a certain blind spot when measuring the height of an object, it is necessary to set the height between the level gauge 23 and the silo bottom 211 to be no less than the sum of the height between the maximum material line H and the silo bottom 211, the blind spot height of the level gauge 23, and the preset safety space height, in order to avoid affecting the measuring function of the level gauge 23.

[0059] The preset safety space height can be set according to actual loading needs. For example, the preset safety space height can be set to 0.2 meters or 0.3 meters. This application does not limit the specific value of the preset safety space height. The position of the highest material line H can also be preset according to actual loading requirements. This application does not limit the specific position of the highest material line H in the main body 212 of the warehouse.

[0060] In some embodiments, the transport vehicle 2 further includes a frame 28 and a bin 29. The frame 28 has a unique vehicle tag on its outer side. The bin 29 is located between the frame 28 and the bin 21. One end of the bin 29 is liftably connected to the frame 28, and the other end is fixedly connected to the bin 21. The loading device 3 includes a loading device 30 and a tag reader 34. The tag reader 34 is located at one end of the loading device 30.

[0061] For details, please refer to Figure 6 The loading device 30 includes a loading bracket 31, a loading assembly 32, and a loading base 33. One end of the loading bracket 31 is rotatably connected to the loading base 33, and the other end is detachably connected to the loading assembly 32. The loading assembly 32 is used to load construction materials into the hopper 21. A label reader 34 is located at the end of the loading bracket 31 near the loading assembly 32.

[0062] In this embodiment, the loading component 32 can be a gripper or a bucket. The appropriate type of loading component 32 can be selected depending on the construction material to be loaded. For example, if the construction material is a fluid substance or granular / powdered material such as cement, gravel, or lime powder, a bucket can be used for loading, i.e., the bucket is installed at the end of the loading bracket 31 away from the loading base 33. If the construction material is a solid substance such as reinforcing steel, a gripper can be used to pick up the construction material for loading, i.e., the bucket is installed at the end of the loading bracket 31 away from the loading base 33. In other embodiments, the loading component 32 can also be a hook for hooking up tower components or large insulators. This application does not limit the specific type of the loading component 32.

[0063] The central controller 1 sends material transportation instructions to the loading equipment 3, controlling the tag reader 34 to scan and identify vehicle tags. After the vehicle passes through, the central controller 30 loads the construction materials in the loading area into the silo 21, so that the transport vehicle 2 transports the construction materials to the target location according to the preset planned path. In this embodiment, the target location is a road point near the transmission line project. Since the transmission line project includes multiple tension sections, each tension section has a corresponding road point, meaning there is a preset planned path from the loading area to each road point. A tension section is the section of the line between two adjacent tension towers in the power system, that is, a section of the line with independent stress and maintenance characteristics, composed of two or more straight towers and tension towers at both ends.

[0064] After the transport vehicle 2 transports the construction materials to the target location, the workers unload the construction materials from the transport vehicle 2. At this time, in order to improve unloading efficiency, the hopper 21 can be raised so that the construction materials in the hopper 21 can slide out from the opening of the hopper body 212. After unloading is completed, the hopper 21 is lowered so that the transport vehicle 2 can complete other loading and unloading tasks.

[0065] In this embodiment, the vehicle code is used to uniquely identify the transport vehicle 2. The material transport instruction includes a preset planned route and the target vehicle code. After receiving the material transport instruction from the central controller 1, the loading device 3 controls the tag reader 34 to scan and identify whether the vehicle tag of the transport vehicle 2 matches the target vehicle code in the material transport instruction. If they match, an identification pass message is generated, and the loading device 30 is controlled to load the construction materials in the loading area into the hopper 21. In this way, the loading device 3 can avoid the situation where the loading device 3 loads the construction materials into other transport vehicles 2 by mistake.

[0066] It should be noted that there can be multiple transport vehicles 2. The central controller 1 sends different material transport instructions to the loading equipment 3, so that the loading equipment 3 transfers the construction materials into the corresponding transport vehicles 2 in the order in which the instructions are received.

[0067] It should also be noted that the label reader 34 in this embodiment can be a QR code / barcode reader or a barcode scanning camera. This application does not limit the type of label reader 34, as long as the label reader 34 can recognize the vehicle code of the transport vehicle 2.

[0068] In some embodiments, the construction site material transportation system further includes an online monitoring instrument 4 and a dust removal system 5. Both the online monitoring instrument 4 and the dust removal system 5 are communicatively connected to the central controller 1. The online monitoring instrument 4 and the dust removal system 5 are located within the loading area and along the road of the preset planned route. The online monitoring instrument 4 is used to monitor the dust levels in the loading area and along the road and send the dust levels to the central controller 1. The central controller 1 is also used to control the dust removal system 5 to start spraying to reduce dust when the detected dust level is greater than the preset dust threshold.

[0069] Online monitoring instruments 4 and dust removal systems 5 are installed within the loading area and along the pre-planned road route. When the construction materials are granular / powdered substances, dust may be stirred up due to the bumps that may occur during transportation by the transport vehicle 2, or during the loading and unloading of construction materials. The online monitoring instrument 4 monitors the dust level in the air at the current location. When the central controller 1 detects that the dust level is greater than the preset dust threshold, it activates the dust removal system 5 to spray and reduce dust, so that the dust level in the air after dust removal is less than the preset dust threshold. The preset dust threshold is set according to the actual air quality requirements, and this application does not limit the specific value of the preset dust threshold.

[0070] In this embodiment, an emergency stop button (not shown), an audible and visual alarm (not shown), a collision avoidance radar (not shown), and a positioning module (not shown) may also be installed in the transport vehicle 2. The emergency stop button, audible and visual alarm, collision avoidance radar, and positioning module are all communicatively connected to the vehicle controller 25 (it is understood that if the vehicle controller 25 is not present, the emergency stop button, audible and visual alarm, collision avoidance radar, and positioning module are all communicatively connected to the central controller 1).

[0071] For example, if transport vehicle 2 encounters an emergency and needs to stop immediately, vehicle controller 25 can control transport vehicle 2 to stop via the emergency stop button. When transport vehicle 2 needs to warn other vehicles or wild animals to stay away, vehicle controller 25 can control the sound and light warning device to issue an alert. While transport vehicle 2 is in motion, the collision avoidance radar detects obstacles along the pre-planned path that could impede normal travel. If an obstacle is found, the radar can automatically slow down or stop transport vehicle 2. While transport vehicle 2 is in motion, the positioning module can also locate its real-time position and send it to the central controller 1, allowing staff to monitor the vehicle's movement.

[0072] The construction material transportation system in this embodiment uses weight sensors and level gauges to detect the weight and height of construction materials loaded into the silos, preventing overloading or overheight issues from affecting material transportation. Furthermore, an insulation layer is wrapped around the outer wall of the silo, and a temperature controller and temperature sensor are installed between the insulation layer and the silo to ensure a constant temperature of the construction materials inside, preventing extreme temperatures from affecting the material's condition and delaying project progress. Vibrators and spray nozzles are installed to improve the unloading rate of construction materials; dual verification using electromagnetic locks and code reading prevents unauthorized unloading during transportation, achieving closed-loop verification of the transportation task; construction materials are loaded onto the transport vehicles only after the tag reader identifies the vehicle code, avoiding the problem of construction materials being loaded onto the wrong transport vehicle. Simultaneously, an online monitoring instrument and dust removal system are installed. If dust levels are detected during transportation and do not meet standards, the dust removal system is activated to spray and suppress dust, ensuring that the construction project meets environmental protection requirements.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
