Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, in an embodiment of the present invention, an intelligent meeting scheduling method in an underground cave roadway includes an in-cave vehicle positioning system, and the meeting scheduling method is based on in-cave vehicle positioning, and therefore further includes an in-cave local area network, where the in-cave local area network includes a base station, a light ring network, a local area network, a server, a management host, and a power supply.
The system also comprises a meeting scheduling strategy, wherein the meeting scheduling strategy comprises a single vehicle and single vehicle condition, a single vehicle and motorcade condition and a meeting early warning starting time.
The scheduling method comprises the following steps:
the method comprises the following steps: firstly, building a local area network in a hole, erecting network base stations at certain intervals, realizing the whole-area coverage of wireless network signals in the hole, installing a positioning card on each engineering vehicle in the hole, enabling the base stations and the positioning cards to communicate in real time, determining the specific position of the positioning card in the hole, realizing the real-time positioning of the vehicles in the hole, and completing the building of the local area network in the hole, wherein the real-time positioning information of a vehicle positioning system in the hole is taken as the basis for the meeting scheduling in the hole, the real-time analysis of the positioning data is used for carrying out meeting early warning prompt and meeting intelligent scheduling, and the basic principle of meeting is shown in fig. 2;
step two: A. b, the two vehicles run in the same direction, when the vehicles run in a roadway, the base station measures the positions of the vehicle positioning cards in real time, and then reports the data to an upper-layer server;
step three: the upper-layer server comprehensively analyzes the real-time position of each vehicle in the hole, and calculates the relative distance between the vehicles to meet and the distance value between the vehicles and the wrong lane;
step four: when the intersection vehicle runs to a certain position or time (according to a meeting scheduling strategy), the system respectively sends meeting early warning instructions to the vehicles, and drivers schedule meeting in real time according to the meeting instruction early warning information.
The early warning information received by the vehicle with higher priority in the fourth step is as follows: the driver of the vehicle can know that the vehicles in front run in the opposite direction after hearing the early warning voice information, and the vehicle needs to be decelerated to prepare for meeting; the early warning information received by the vehicle with lower priority is as follows: the driver of the vehicle can also know that vehicles running in the same direction exist in the front, and the driver needs to enter a staggered vehicle hole in the front to avoid according to the instruction requirement to complete meeting.
Fig. 2 only describes the meeting scheduling strategy in a simple situation, and the method establishes various meeting scheduling strategies for various meeting situations in a hole respectively. The method establishes corresponding priorities aiming at different meeting scheduling strategies, and carries out intelligent scheduling according to the priorities, wherein vehicles with high priorities run at a reduced speed during meeting, and vehicles with low priorities enter wrong car holes to avoid. The specific meeting scheduling strategy is as follows:
(1) bicycle and bicycle situations. When a bicycle meets with a bicycle, different priorities are set for different vehicle types, the priority of a common trolley is lower than that of an engineering vehicle, the lowest priority is 1, and the priorities can be accumulated according to the priorities of different situations. For example, if the priority of the trolley is 1 and the priority of the engineering truck is higher than that of the trolley by one level, the priority is 1+1, i.e. 2. And under the condition that the priorities are the same, the priority of the vehicle entering the hole is lower than that of the vehicle leaving the hole according to the driving direction.
(2) Both single car and fleet situations. More than two vehicles run in the same direction in the hole, and the distance between the vehicles is less than 50 meters (adjustable) to position the fleet. The motorcade is far higher than the priority of the single vehicle, and the single vehicle avoids the motorcade during meeting.
(3) Fleet and fleet scenarios. The motorcade and the motorcade meet, the part with less vehicles forming the motorcade has higher priority, and the priority of the entry motorcade is lower than that of the exit motorcade under the condition that the vehicles of the two motorcades have the same number.
The above is defined for the priority in the meeting process. In addition to defining the priority in the vehicle strategy, the problem of the start time of the vehicle crossing early warning needs to be considered, if the vehicle crossing early warning is started late, a vehicle crossing hole can be missed, the vehicle crossing hole cannot be reasonably utilized due to too early starting, and meanwhile, the vehicle crossing efficiency is reduced. Therefore, the vehicle crossing early warning is started at a reasonable time.
The design of the meeting early warning time is defined according to the relation between the number of staggered holes between the vehicles meeting and the number of vehicles in one direction. According to a meeting scheduling strategy, one side with low priority enters the wrong-way hole to avoid, so when the meeting early warning opportunity is started, when the quantity of the wrong-way holes between two vehicles (or two motorcades) running oppositely is one more than the quantity of the wrong-way holes needing to enter (namely the quantity of the wrong-way holes is equal to the quantity of the vehicles in the avoided motorcade plus 1), the meeting early warning is started. For example, when a bicycle meets with a bicycle, and two staggered holes are formed between the bicycle and the bicycle, the vehicle meeting early warning is started. When the two parties receive the meeting early warning instruction, one passing hole is probably missed between the two parties, and the successful meeting can be ensured only by the remaining passing hole; for another example, when a fleet meets with a fleet, assuming that the fleet with low priority is the fleet consisting of 2 motor trains, when three staggered holes are necessary between the two fleets, the meeting early warning is started, and a meeting dispatching instruction is sent out. Therefore, when a meeting command is received, enough vehicle passing holes are available in front.
The method for meeting vehicles in the hole completely adopts an intelligent automatic scheduling mode, and the monitoring terminal can monitor the conditions of the vehicles in the hole in real time without human intervention. And in each situation, big data analysis is carried out on the positioning information, and the meeting scheduling is automatically completed according to a preset scheduling strategy.
The working principle of the invention is as follows:
when in use, firstly, a local area network is built in a hole, network base stations are erected at certain intervals to realize the whole area coverage of wireless network signals in the hole, positioning cards are installed on each engineering vehicle in the hole, the base stations and the positioning cards can communicate in real time, the specific positions of the positioning cards in the hole are determined, the real-time positioning of the vehicles in the hole is realized, the building of the local area network in the hole is completed, A, B the two vehicles move in opposite directions, when the vehicles run in a roadway, the base stations measure the positions of the vehicle positioning cards in real time, then data are reported to an upper layer server, the upper layer server comprehensively analyzes the real-time positions of all the vehicles in the hole, the relative distance of the vehicles to be met and the distance value between the vehicles and a wrong lane are calculated, when the vehicles run to a certain position or at a certain time, a system respectively sends meeting early warning instructions to the vehicles, and drivers can schedule vehicles in real time according to the, wherein the early warning information received by the vehicle with higher priority is as follows: the driver of the vehicle can know that the vehicles in front run in the opposite direction after hearing the early warning voice information, and the vehicle needs to be decelerated to prepare for meeting; the early warning information received by the vehicle with lower priority is as follows: the driver of the vehicle can also know that vehicles running in the same direction exist in the front, and the driver needs to enter a staggered vehicle hole in the front to avoid according to the instruction requirement to complete meeting.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
