Description

Technical Field

[0001] The present invention relates to the technical field of mine safety monitoring, and in particular to an information control device of a mine ramp vehicle-mounted traffic command system. Background Art

[0002] At present, the safety of vehicle transportation on mine ramps has always been a weak link in the safety management of mine vehicle transportation. Electric trucks, diesel trucks and other trackless vehicles for transporting ore, waste rock and materials, as well as jeeps, explosive trucks, tankers, special vehicles and other service vehicles all operate on mine ramps, and the cross-sectional dimensions of the main ramps are usually difficult to meet the needs of trackless vehicles passing each other, and vehicles often get stuck and even cause traffic accidents; at the same time, due to the complex structure of underground tunnels, many branches and interconnectedness, the mixed operation of multiple vehicles has buried a major hidden danger in the safety management of vehicle transportation.

[0003] Faced with the situations of multiple types of vehicles, one-way road conditions, a large number of vehicles passing up and down, and different passing capacity on the mine ramp, a signal light management system is currently usually used to direct vehicles. For example, the patent with publication number CN105843150A provides a single-lane vehicle operation control signal system in a mine and its control method. The patent uses a single-lane fixed meeting point vehicle operation control signal system in the mine to track, monitor, and locate underground vehicles in real time, effectively solving driving accidents such as avoidance, rear-end collision, and collision of single-lane vehicles in the mine, reducing fuel consumption and loss of human resources caused by frequent reversing, thereby reducing production costs. However, the control signal for vehicle operation in the patent is only a single signal light, and the vehicle conditions corresponding to the changes in different signal lights are very complicated, which is prone to errors in practical applications; at the same time, the vehicle operation control signal system provided by the patent can provide less vehicle information, and it is difficult for the mine car driver to fully understand the vehicle condition, which is not conducive to making accurate decisions, and safety hazards still exist.

[0004] In view of this, in order to ensure the safety of mine production and vehicle transportation, it is necessary to design an improved information management and control system to provide more comprehensive and effective vehicle condition information for underground transportation vehicles to solve the above problems. Summary of the invention

[0005] In view of the defects of the above-mentioned prior art, the purpose of the present invention is to provide an information control device for the on-board traffic command system of the mine ramp. By extracting and analyzing the front and rear vehicle information and the information of the passing lane, and setting four windows to display the information of the reverse vehicle in front of this logical area, the reverse vehicle and the passing lane information in the front logical area, the number of vehicles in the same direction in this logical area, and the ranking and ramp vehicle overview information, the driver is assisted to make accurate decisions on passing, waiting or reversing to avoid, effectively avoiding the congestion of transport vehicles and ensuring transportation safety.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0032] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] like Figures 1 to 11As shown, the present invention provides an information control device for a mine ramp vehicle-mounted traffic command system, including an information collection module for collecting vehicle information, a display module connected to the information collection module and used to display vehicle information, and a communication module for realizing information transmission; the display interface of the display module includes an information window of reverse vehicles in front of this logical area, an information window of reverse vehicles and wrong lanes in the front logical area, a window of the number of vehicles in the same direction and their ranking in this logical area, and an overview information window of ramp vehicles.

[0034] In one embodiment of the present invention, the information collection module includes a static information storage unit and a dynamic information collection unit; the vehicle position information collected by the dynamic information collection unit corresponds to the vehicle static information pre-stored in the vehicle static information storage unit, so that the information collection module can fully obtain vehicle information. Among them, the dynamic information collection unit includes a vehicle positioning card set in the vehicle for collecting the vehicle position information, and the distance from the vehicle to the front passing lane collected by the vehicle positioning card is represented by the letter D; the vehicle static information includes the license plate, driver, vehicle type, vehicle length and vehicle width, wherein the vehicle length and vehicle width are represented by the letters L and W respectively. The above vehicle information includes the vehicle information of the vehicle and the vehicle information of other vehicles in the mine ramp. In other embodiments of the present invention, the vehicle static information storage unit also pre-stores the information of the passing lane, including the position, length and width of each passing lane.

[0035] In one embodiment of the present invention, the communication module includes a voice intercom device arranged in the vehicle and the dispatch room, which is used to realize voice intercom between vehicles or between the vehicle and the dispatch room.

[0036] See also Figures 2 to 4 In one embodiment of the present invention, the display content of the oncoming vehicle information window in front of this logical area includes the distance between the head vehicle of the oncoming vehicle in front of this logical area and the lane just passed, the distance between the vehicle and the lane just passed, and the oncoming vehicle information in this logical area.

[0037] When there is a vehicle going in the opposite direction in this logic zone, since the ramp is a one-way street, one party must reverse, and the vehicle closer to the wrong lane can be selected for reverse according to the distance of the parties to the wrong lane. In one embodiment of the present invention, the distance between the leading vehicle of the opposite direction in front of this logic zone and the wrong lane just passed is 20m, and the distance between the vehicle and the wrong lane just passed is 550m. At this time, the information window of the opposite vehicle in front of this logic zone is displayed in red, which is used to prompt the leading vehicle of the opposite direction in front of this logic zone, which is closer to the wrong lane just passed, to reverse. In other embodiments of the present invention, the display color of the window can also be other colors, as long as it serves as a prompt, and the present invention is not limited to this.

[0038] See also Figures 5 to 7In one embodiment of the present invention, the display content of the window of information on opposite vehicles and wrong lanes in the logical area ahead includes the number of opposite vehicles in the logical area ahead, the maximum vehicle type in the logical area ahead, information on opposite vehicles in the logical area ahead, and information on the wrong lane ahead; the information on the wrong lane ahead includes the distance from the vehicle to the wrong lane, the width of the wrong lane, and the length of the wrong lane.

[0039] When the number of reverse vehicles in the logical area ahead is ≥ 1, it indicates that there is a reverse vehicle in the logical area ahead, and it is strictly forbidden to run into the wrong lane, and you must wait for the wrong vehicle in the wrong lane. In one embodiment of the present invention, the number of reverse vehicles in the logical area ahead is displayed as 7, indicating that there are 7 reverse vehicles in the logical area ahead. At this time, the number of reverse vehicles in the logical area ahead, the reverse vehicle information in the logical area ahead, the distance from the vehicle to the wrong lane, and the position corresponding to the length of the wrong lane are all displayed in yellow, which is used to remind the driver that he must wait for the wrong lane to pass the vehicle. In other embodiments of the present invention, the above-mentioned positions can also display other colors to serve as a reminder, and the present invention is not limited to this.

[0040] When the sum of the width of the largest vehicle in the logical area ahead and the width of the vehicle itself is greater than the width of the passing lane, one party must reverse, and the party with fewer vehicles can be selected to reverse according to the number of vehicles on each side. At this time, the positions corresponding to the largest vehicle in the logical area ahead and the width of the passing lane are both displayed in red to prompt the need to reverse. In other embodiments of the present invention, the above positions can also display other colors to serve as a prompt, and the present invention is not limited to this.

[0041] See also Figures 8 to 10 In one embodiment of the present invention, the display content of the number of vehicles in the same direction and the ranking window in this logical area includes the number of vehicles in the same direction in this logical area and the ranking they are in, the total length of the front vehicle and the vehicle itself, and the information of vehicles in the same direction in this logical area.

[0042] When there are too many vehicles going in the same direction in this logic area, and the total length of the preceding vehicle plus the vehicle is greater than the length of the passing lane, it indicates that the lane may have insufficient space for passing. In one embodiment of the present invention, the total length of the preceding vehicle plus the vehicle is 24.2m, and the length of the passing lane ahead is 20m. At this time, the position corresponding to the total length of the preceding vehicle plus the vehicle is displayed in yellow to indicate that passing ahead is difficult. In other embodiments of the present invention, the position corresponding to the total length of the preceding vehicle plus the vehicle may also display other colors to serve as a prompt, and the present invention is not limited to this.

[0043] See also Fig.11 In one embodiment of the present invention, the ramp vehicle overview information window displays the location information of the vehicle in the mine ramp to assist the driver in judging the ramp traffic pressure and assist the driver in planning the destination.

[0044] The working principle of the information control device of the mine ramp vehicle traffic command system provided by the present invention is described below:

[0045] First, a vehicle positioning card for collecting the vehicle position information is set in the vehicle, and the information of the vehicle positioning card is associated with the static information of the vehicle, such as the license plate, vehicle model, vehicle length, vehicle width, driver, etc. When the information control device of the mine ramp vehicle traffic command system provided by the present invention is started, the information collection module obtains the real-time position information of the vehicle positioning card and the vehicle information and wrong lane information pre-stored in the storage unit, and transmits them to the display module.

[0046] The display module then displays the received vehicle information and the passing lane information in the display interface. The display interface of the display module includes four windows: the information window of the reverse vehicle in the front logical area, the information window of the reverse vehicle and the passing lane in the front logical area, the number of vehicles in the same direction in the current logical area and the ranking window, and the overview information window of the ramp vehicles.

[0047] Among them, the driver can observe the information of the reverse vehicle in front of this logical area and its distance from the wrong lane according to the reverse vehicle information window in front of this logical area, and pay attention to reverse when seeing the window shows red; observe the information of the reverse vehicle in front of the logical area according to the reverse vehicle and wrong lane information window in front, pay attention to waiting for the wrong vehicle when seeing the window shows yellow, and pay attention to reverse when seeing the window shows red; and observe the number of vehicles in the same direction in this logical area and their ranking according to the number of vehicles in the same direction in this logical area and the ranking window, and pay attention to the difficulty of passing the vehicle ahead when seeing the window shows yellow, so as to make adjustments. At the same time, the driver can also display the location information of the vehicle in the mine ramp according to the ramp vehicle overview information window, so as to assist the driver to judge the traffic pressure of the ramp and assist the driver to plan the destination.

[0048] Based on the window of the display module, the driver can fully obtain the vehicle information in the mine ramp so as to make accurate decisions on passing, waiting or reversing to avoid. After making a decision, the driver can send the decision content to other drivers through the voice intercom device in the communication module; or before making a decision, he can communicate with other drivers through the voice intercom device to jointly confirm the decision method. When the driver does not notice the color prompt in the display interface, the staff in the dispatch room or other drivers can also remind him through the voice intercom device to ensure that all vehicles in the mine ramp can pass and avoid in an orderly manner, thereby effectively avoiding congestion of transport vehicles and ensuring transportation safety.

[0049] In summary, the present invention provides an information control device for a mine ramp vehicle traffic command system, including an information collection module for collecting vehicle information, a display module connected to the information collection module and used to display vehicle information, and a communication module for realizing information transmission; the display interface of the display module includes an information window of the reverse vehicle in front of this logical area, an information window of the reverse vehicle and the wrong lane in the front logical area, a window of the number of vehicles in the same direction and their ranking in this logical area, and an overview information window of vehicles on the ramp. Through the above-mentioned method, the present invention can accurately collect and analyze the information of the front and rear vehicles, and set four windows to display the information of the reverse vehicle in front of this logical area, the information of the reverse vehicle and the wrong lane in the front logical area, the number of vehicles in the same direction and their ranking in this logical area, and the overview information of vehicles on the ramp, so as to assist the driver to accurately make decisions on passing, waiting, or reversing to avoid, effectively avoid congestion of transport vehicles, and ensure transportation safety.
