[0039] Figure 1 A schematic diagram of a train loading communication command system provided by the embodiments of the present application is shown in FIG. 1. Figure 1 The embodiments of the present application provide a train loading communication command system 100, which comprises:

[0040] The wireless base station 110 is installed at the loading station.

[0041] The monitoring device is used for collecting the loading state of the train 200, the real-time speed and the current position information in real time;

[0042] The central control device 120 is connected with the wireless base station 110 and the monitoring device, and is used for generating a driving instruction according to the data collected by the monitoring device, wherein the driving instruction comprises a forward, parking, reverse, acceleration and deceleration instruction for controlling the movement of the train 200;

[0043] The wireless bridge 130 is installed on the top of the train 200, and is used for receiving the signal of the wireless base station 110;

[0044] The wireless signal transmitter 140 is installed in the operation room of the train 200, and is connected with the wireless bridge 130 through a network cable, and the wireless signal transmitter 140 is configured to construct a local area wireless network by transmitting a wireless signal;

[0045] The terminal device 150 is configured to access the local area wireless network, and the terminal device 150 is used for receiving and displaying the driving instruction to guide the driver of the train 200 to execute the driving instruction.

[0046] The train loading communication command system 100 provided by the embodiment of the utility model through the wireless base station 110 installed in the loading station as the communication hub provides basic communication support for the whole system. The monitoring device collects the loading state of the train 200, the real-time speed and the current position information in real time, and transmits these data to the connected central control device 120. The central control device 120 generates the driving instruction such as forward, parking, reverse, acceleration and deceleration based on the received accurate data. The wireless bridge 130 installed on the top of the train 200 receives the signal of the wireless base station 110, and then transmits the signal to the wireless signal transmitter 140 in the operation room of the train 200 through the network cable. The wireless signal transmitter 140 transmits the wireless signal to construct the local area wireless network, so that the terminal device 150 can access the network, receive and display the driving instruction, and guide the driver of the train 200 to execute the corresponding operation. The train loading communication command system 100 provided by the embodiment of the utility model avoids the interference of factors such as thinking habit, expression ability and dialect through the automatic data collection, instruction generation and transmission mechanism, ensures the accurate and clear transmission of the instruction, and significantly improves the efficiency and safety of the loading operation of the train 200.

[0047] In the above embodiment, the wireless base station 110 includes an omnidirectional antenna, and the tilt angle of the omnidirectional antenna is adjustable. Among them, the omnidirectional antenna with adjustable tilt angle can greatly enhance the flexibility and effectiveness of signal coverage. By adjusting the tilt angle of the antenna, the signal coverage range and strength can be accurately optimized according to the actual topography of the loading station, the distribution of the train 200 track, and the surrounding environmental interference and other factors, to ensure stable and reliable communication between the train 200 and the base station in different scenarios, and to avoid command transmission errors or delays caused by signal blind area or interference. For example, when there are high buildings and complex topography around the loading station, the traditional fixed antenna signal coverage has many blind areas, after using the base station antenna in the embodiment, the technical personnel can adjust the tilt angle of the omnidirectional antenna to a specific angle according to the actual situation on site, so that the signal can effectively bypass the obstacles and cover the entire loading area and the train 200 track. In actual operation, the train 200 can stably receive the train operation command during the entire loading process, the command transmission success rate is greatly improved, the loading operation efficiency is obviously improved, and the safety accident hidden danger caused by communication problems can also be significantly reduced.

[0048] In the above embodiment, the omnidirectional antenna can cover the entire range of the train 200 from entering the station to leaving the station. The omnidirectional antenna realizes the full-travel signal coverage of the train 200, which can ensure that the train 200 can maintain stable and uninterrupted communication with the central control device 120 during the entire loading process, whether it is in the process of entering the station, loading or leaving the station. This enables the train operation command to be timely and accurately conveyed to the driver, avoiding problems such as command delay, incorrect execution caused by signal interruption or instability, improving the continuity and accuracy of the loading operation, and thereby improving the overall operation efficiency. At the same time, stable communication also helps to discover and handle abnormal situations during the operation of the train 200 in a timely manner, enhancing the safety of the operation.

[0049] In the above embodiment, the wireless base station 110 can further include a mounting rack and a damping assembly, the omnidirectional antenna is mounted on the top of the mounting rack, the mounting rack is installed on the ground, and the damping assembly is arranged between the bottom of the mounting rack and the ground. The damping assembly can improve the stability of the omnidirectional antenna in complex working conditions. When the train 200 passes or the ground vibration caused by the surrounding mechanical operation, the damping assembly at the bottom of the mounting rack can absorb most of the vibration energy, so as to avoid the signal transmission angle deviation caused by mechanical vibration. Specifically, the damping assembly can be composed of a three-stage vibration isolation system including a metal spring group, a hydraulic damper and a high-elasticity rubber pad. The metal spring group provides basic support and absorbs low-frequency vibration, the hydraulic damper attenuates the medium-frequency vibration energy through fluid damping, and the rubber pad further isolates high-frequency impact. The structure can be rigidly connected with the mounting rack bottom plate and the ground pre-buried steel plate through bolts, and the damping layers can be combined with pin shaft hinges and limiters to allow the mounting rack to produce controllable displacement compensation in the horizontal direction while limiting excessive deviation. The damping assembly can effectively reduce the influence of mechanical vibration on the antenna, ensure that the omnidirectional antenna always maintains a stable posture, and thus ensure the continuous and reliable transmission of the loading instruction.

[0050] In the above embodiment, the wireless bridge 130 can include a directional antenna, and the directional antenna is a parabolic antenna. The installation angle of the directional antenna is horizontally aligned with the omnidirectional antenna of the wireless base station 110. By optimizing the antenna configuration of the wireless bridge 130, the stability and anti-interference ability of signal transmission can be significantly improved. Specifically, the wireless bridge 130 uses a parabolic directional antenna, the installation angle of which is horizontally aligned with the omnidirectional antenna of the loading station wireless base station 110, forming a directional signal transmission link. The high-gain characteristic of the parabolic antenna can be used to concentrate signal energy in a specific direction, effectively reducing interference signals in other directions. The horizontally aligned installation method can ensure that the signal path between the base station and the vehicle-mounted bridge is the shortest and unobstructed, thereby enhancing the signal strength. In addition, the focusing property of the parabolic antenna can also reduce the attenuation of the signal in the transmission process, improving the reliability of the communication link, and ensuring that the train 200 can still stably receive the instruction under high-speed running or complex working conditions. Furthermore, the directional design of such directional antenna is also more suitable for complex environments, for example, when there are buildings or large machinery in the surrounding loading station, it can effectively suppress reflected wave interference and ensure real-time and reliable transmission of the loading instruction.

[0051] In the above embodiment, the wireless signal transmitter 140 comprises a MIMO antenna array. The use of MIMO antenna array technology in the wireless signal transmitter 140 can improve the uniformity of signal coverage in the carriage and reduce signal blind areas in the vehicle. Specifically, the MIMO antenna array can dynamically adjust the signal transmission direction through multi-antenna cooperation and intelligent beamforming algorithm to form a three-dimensional coverage network in the operating room of the train 200. For example, in a multi-carriage train 200, the system can uniformly distribute signal energy to each carriage area through spatial diversity technology, especially for traditional weak signal locations such as carriage connections, and can enhance signal strength through adaptive beam adjustment to effectively reduce signal blind areas. This design can ensure that the terminal device 150 can stably receive instructions at any position in the carriage, and solves the problem of local signal interruption caused by shielding in traditional single-antenna systems, and provides a reliable communication foundation for multi-device collaborative operation.

[0052] In the above embodiment, the monitoring device can include a position sensor, a speed sensor, and a weight sensor for detecting the position, speed, and load of the train 200, respectively. By integrating multiple types of monitoring devices, comprehensive perception and precise control of the running state of the train 200 can be achieved. Specifically, the position sensor can obtain the coordinate information of the train 200 on the track in real time to provide spatial positioning basis for generating driving instructions; the speed sensor can continuously monitor the driving speed of the train 200 to support dynamic adjustment of control parameters; and the weight sensor can collect real-time carriage load data to optimize the loading strategy. When the train 200 enters the loading area, the position sensor can obtain real-time relative position data of the vehicle and the loading port, and the speed sensor can monitor the current driving speed. Based on these two sets of data, the central control device 120 generates a "deceleration alignment instruction" to gradually reduce the speed of the train 200 by controlling the braking system, and adjusts the driving trajectory to ensure that the carriage and the loading port are accurately aligned at the specified position. At the same time, by continuously monitoring the load change, the system can optimize the loading rhythm to ensure balanced load of each carriage. This process does not require manual intervention and is completely automated, avoiding overshoot or deviation problems that may occur in traditional manual operation, and improving the loading efficiency.

[0053] In the above embodiment, a switch can also be included, and the wireless base station 110 and the monitoring device are both connected to the central control device 120 through the switch and a wired connection. By deploying the switch, a more stable and reliable wired communication backbone network can be constructed, and the data transmission efficiency and anti-interference ability of the system are improved. As a central hub device, the switch realizes the centralized access of the wireless base station 110 and the monitoring device (position, speed, and weight sensor), and ensures that the central control device 120 can obtain complete train 200 state data in real time. The introduction of the wired communication link can effectively reduce the influence of signal attenuation and electromagnetic interference, and ensure the accurate and error-free transmission of the driving instruction. At the same time, the switch supports multi-device concurrent access and priority management, and in the scenario of multiple trains 200 operating at the same time, the priority transmission of the key control instruction can be ensured, and the instruction delay caused by network congestion can be avoided. In addition, the redundant design of the switch itself can also enhance the fault tolerance of the system, and when a link fails, it can automatically switch to a backup path to ensure communication continuity. This architecture provides a high-bandwidth, low-latency, and high-reliability data transmission channel for the intelligent loading control under complex working conditions, and provides a reliable foundation.

[0054] In the above embodiment, a storage device can also be included, which is hot-pluggable connected to the central control device 120, and the storage device is used to store the loading log of the past at least one year, and the loading log includes the loading time, the load weight, and the train 200 identity information. By integrating the hot-pluggable storage device, the data management capability and traceability of the system can be improved. The storage device supports the hot-pluggable function of plug and play, which can ensure that storage expansion or fault replacement is realized without interrupting the system operation. The loading log stored in the storage device can not only be used for job process optimization, but also can provide data support for scheduling strategy by analyzing the loading efficiency, load distribution, and other parameters at different time periods, and can provide a basis for responsibility tracing and safety audit, and facilitate quick positioning of abnormal event causes.

[0055] In the above embodiment, the terminal device 150 can be a tablet computer, a mobile phone, or a vehicle-mounted display screen. Among them, the terminal device 150 supports multiple types of devices such as tablet computers, mobile phones, and vehicle-mounted display screens to access, which improves the flexibility and operation convenience of instruction interaction. These terminal devices 150 receive the driving instructions (such as forward, stop, load warning, etc.) generated by the central control device 120 in real time through a local wireless network, and are displayed intuitively in a graphical interface. Among them, the portable nature of the tablet computer and the mobile phone allows the driver to view the job information flexibly inside and outside the vehicle, and the fixed installation of the vehicle-mounted display screen provides clear visualization support for the driving position. The multi-terminal adaptive design enhances the environmental adaptability of the system, for example, in a cold or dusty environment, the vehicle-mounted display screen can ensure stable display through industrial protection design; in the temporary operation scenario, the tablet computer can be quickly deployed for emergency command.

[0056] Specifically, the terminal device 150 can use a tablet computer, on which driving instructions, vehicle speed, loading data, and alarm prompts, etc. can be displayed. The driving instructions can include "go forward, stop, go backward, accelerate, decelerate", etc. The vehicle speed can include "current vehicle speed, optimal vehicle speed, upper limit of vehicle speed, lower limit of vehicle speed", etc. The loading data can include loading state, loading progress, and load information, wherein the loading state can include "waiting for loading, loading, pausing, fault, loading complete"; the load information can include "loaded weight, target weight, deviation, total target", etc. The alarm prompts can include "overspeed, overloading, unbalanced loading, system fault, insufficient storage", etc.

[0057] The following lists a possible loading process in actual operation: when the train arrives at the loading station, the driver can use the tablet computer to connect to the wireless network, the dispatch center sends a loading task sheet to the tablet, the driver checks the train number, train type and freight information, and clicks the confirmation button on the tablet, and the information is fed back to the dispatch center. The dispatch center starts the loading system at the appropriate time, and when the loading system is started, the central control device 120 sends a forward voice prompt to the train driver according to the data monitored by the monitoring device, and prompts the distance between the train 200 and the remaining parking place. When the first car arrives at the predetermined parking interval, the central control device 120 sends a parking message to the tablet, and starts loading the first car. When the first car starts loading, the central control device 120 sends a forward instruction to the tablet, and during the loading process, the "progress, load, real-time vehicle speed, target vehicle speed", etc. are displayed on the tablet interface. The driver adjusts the vehicle speed according to the target speed at any time, and when the speed deviation is too large, the central control device 120 automatically sends a speed adjustment instruction to the tablet. When the speed is too high, the central control device 120 sends an alarm to the tablet, and continuous overspeed will automatically stop the loading and prompt the driver to stop immediately. When an accident occurs and the train needs to go backward to reload, the central control device 120 sends a backward instruction to the driver according to the vehicle positioning condition, and prompts the parking point. Then each car is loaded according to the loading logic of the first car, until the loading is completed.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
