Description
Technical Field
The invention belongs to the technical field of mine traffic, and particularly relates to a method for controlling a signal lamp under a mine.
Background
Since the mine is environmentally complicated, it is necessary to ensure the safety of personnel on the one hand and to improve the operation efficiency of the equipment on the other hand. Underground transportation is a key link of mine production, and with increasing importance on mine safety and continuous enhancement of supervision of the country, underground transportation safety production monitoring systems of large and medium-sized mining enterprises are developed and equipped.
The distribution of the underground roadways of the mine is the same as that of ground traffic, and the complexity is high. At present, signal lamps are not installed in existing mines, and along with increasing underground vehicles (people transporting vehicles, material transporting vehicles, command vehicles, mine transporting vehicles and the like), roadway congestion and collision accidents occur frequently, so that safety is affected, and production efficiency is affected.
Because the underground traffic and the ground traffic are controlled in different ways. For production needs, the signal lamps cannot be controlled in a way that red and green signal lamps alternate cyclically, so the control method is more complicated than the ground signal lamp control. Because the control is complicated, the traffic light management mode of some mines is controlled manually, namely when a vehicle arrives at a certain intersection, a driver of the vehicle controls the lights of the opposite intersections to turn into red lights. Therefore, the control of the signal lamp is low in efficiency, unsafe and incapable of completely meeting the production requirement.
Unlike ground roads, the underground roadway of the mine can be constructed into a bidirectional multilane. Due to the cost and safety requirements, many places or old mines basically adopt a one-way and two-way construction mode, namely a mode of only one lane passing in two ways. In this mode, the dependence on traffic lights is high.
Main intersection types of the mine underground road:
breaking the head: as shown in fig. 1, in order to facilitate disposal of waste such as waste rocks and garbage on a mine, a waste disposal site 11 is specially repaired at some place downhole on the mine. The path to such a location is a broken path. In this place, only one vehicle can enter. After the garbage is poured in, the garbage is poured out, and after the garbage is driven out, another vehicle can enter. Therefore, a signal lamp 10 is required to be installed at the broken-end intersection, when a vehicle enters, the signal lamp is arranged to be red to remind other vehicles that the vehicle cannot enter, other vehicles need to wait in the lane 20 for the vehicle to pass by, after the vehicle in the lane comes out, the signal lamp is arranged to be green, and then other vehicles enter again. The intersection is simple to control, and can be controlled by a common driver manually, so that the defect is that the control is troublesome, and once the driver forgets to control or recover, traffic jam can be caused.
One-way path: as shown in fig. 2, in some areas, one-way roads are constructed for cost savings and for quick construction. Only one vehicle can pass through the one-way lane at the same time, and other vehicles need to wait at the carport 20. When the vehicles on the one-way road go out of the one-way road, the vehicles in the opposite direction can enter the one-way road, otherwise, traffic jam can be caused. The one-way control method is more complicated than the broken road, the condition that two parties come needs to be considered, and 2 signal lamps 10 need to be installed. When no vehicle is in use, both sides are green lights. When one side of the vehicle comes in, one side of the vehicle keeps a green light and the other side of the vehicle turns into a red light. When the vehicle goes out of the one-way road, whether the vehicle follows the rear of the vehicle or not needs to be judged, and if the vehicle follows the rear of the vehicle, the current states of the 2 signal lamps are kept unchanged. When all following vehicles pass through the one-way road, whether vehicles to be driven exist in the lane of the vehicle passing by on one side of the red light needs to be judged. If there is a vehicle waiting to run, the red light is set to green, and the other side is set to red. And if one side of the red light corresponds to the lane of the vehicle passing by without the vehicle to be driven, the red light is placed to be green.
For a one-way road, if a signal lamp is manually controlled, the control is troublesome. The driver of the front vehicle cannot know whether the rear vehicle follows or not. 2 signal lamps need to be controlled simultaneously to make corresponding changes. Traffic congestion occurs as soon as control is wrong or forgotten. If the traditional program control method is adopted, the implementation is complex, separate control methods need to be provided for the signal lamps on two sides of each one-way road, and the control program becomes complex along with the increase of the number of the one-way road sections.
The T-shaped intersection: as shown in fig. 3, the control of the t-port signal light is more complicated than the one-way lane control. When a vehicle arrives at one intersection, the signal lamps 10 at the other two intersections need to be red because the vehicle cannot be judged to turn in which direction. After the vehicle passes through another signal lamp or turns over a bend, whether the following vehicle exists or not is judged. If the car is followed, the signal lamp is kept unchanged. After the follow-up car turns over the bend. Vehicles can pass through other intersections. At this time, because there are 2 red light intersections, it is necessary to determine whether there are vehicles waiting to run at the two red light intersections. And if no vehicle to be driven exists, placing the signal lamps of the two red light intersections to be green, and waiting for the vehicle to pass. If only one red light intersection has the vehicle to be driven, the original green light intersection is placed with the red light, and the red light of the vehicle to be driven is placed with the green light. The vehicle to be driven can pass through. And after the waiting vehicle passes through another signal lamp or turns over a bend, continuously judging whether a following vehicle exists behind the waiting vehicle. If the car is followed, the state of the signal lamp is kept unchanged. If the vehicle is not followed, judging whether vehicles to be driven exist at the other two intersections. If vehicles to be driven exist at the other two intersections, the vehicles at the intersection are judged to arrive first, the signal lamps of the intersection are turned green, and the signal lamps of the other two intersections are turned red.
At a multi-branch road: as shown in fig. 4, there are many intersections such as crossroads, five-way intersections, six-way intersections, and the like in the mine, and the control of the intersection signal lamps 10 is more complicated. When a vehicle comes from one intersection, other intersections wait until the vehicle passes through the intersection, and the vehicles at the other intersections can not pass through. The problem of who is led to the first place due to the plurality of waiting intersections. If conventional control methods are used, each intersection provides a separate control algorithm. One is that the control logic is complex, referring to the T-shaped intersection control logic, the multi-branch intersection control logic of crossroads, five-fork intersections, six-fork intersections and the like is very complex. The other is the inability to flexibly strain. The logic is hard to realize, and along with production requirements, if an intersection is additionally arranged on a roadway, the original control logic fails, the control logic needs to be developed again, time and labor are consumed, and the test is not good.
In the present invention, the one-way road, the t-junction, and the various multi-branch intersections are collectively referred to as an intersection.

Detailed Description
As shown in fig. 5, the method for controlling the underground signal lamp of the mine is provided with a mine traffic controller 100, a signal lamp group database 200, a vehicle priority database 300 and a signal lamp priority database 400. Each vehicle 500 is configured with a last-time-passing signal lamp cache 501, and each signal lamp 600 is configured with a pending vehicle cache 601.
The mine traffic controller 100 communicates with the signal light group database 200, the vehicle priority database 300, the signal light priority database 400, each vehicle 500, each last pass signal light cache 501, each signal light 600, and each pending vehicle cache 601. The mine traffic controller 100 communicates with the beacons placed on the vehicle 500, and the accurate positioning of the vehicle 500 under the mine is realized through the beacons.
The mine traffic controller 100 can acquire the position information of each signal lamp based on an underground electronic map of a mine, can also acquire the red and green state of each signal lamp, can acquire the position information of each vehicle in real time through an underground accurate positioning technology, and can also control the red and green state of each signal lamp. Since the mine traffic controller can acquire the signal lamp position information and the red and green states and acquire the vehicle position information through the mine underground accurate positioning technology is the prior art known by all the technicians in the field, the description is omitted here.
The signal lamp grouping database groups signal lamps, and the grouping is divided according to the specific conditions of the intersection, for example: the broken road only needs a signal lamp control, consequently divide into a set of with a signal lamp on broken road, and the one-way road needs two signal lamp control, consequently divides into a set ofly two signal lamps of one-way road head and the tail, and the T-shaped crossing needs three signal lamp to control, consequently divides into a set ofly with the three signal lamp that the T-shaped crossing corresponds, and the crossroad needs four signal lamps to control, consequently divides into a set ofly with four signals that the crossroad corresponds, … …, to the crossroad promptly, each signal lamp of same crossroad is divided into a set ofly.
The signal lamps of the same lamp group have the attribute of mutual exclusion, namely, in the same lamp group, when a vehicle arrives, only one signal lamp is green at the same time, and the other signal lamps are all red. For example, a lamp group consisting of two signal lamps A, B at two ends on a one-way road is "mutually exclusive": the method comprises the following steps that (1) a vehicle comes from an A end, a signal lamp of the A end is kept to be a green lamp, and a signal lamp of a B end is required to be a red lamp; similarly, when a vehicle comes from the end B, the signal lamp at the end B is kept to be a green lamp, and the signal lamp at the end A needs to be a red lamp, otherwise, traffic jam can be caused. The signal light group formed by the three signal lights of the T-junction A, B, C must be mutually exclusive: when a vehicle comes from the port A, the signal lamp at the port A is kept to be green, and the signal lamp at the port B, C needs to be red; the automobile comes from the port B, and the signal lamp at the port A, C needs to be a red lamp; the traffic light at A, B needs to be red light.
The last-time passing of the traffic light buffer 501 is used to record the traffic light identification code of the vehicle passing, but only records the traffic light identification code of the last passing of the vehicle, and deletes the previous-time passing traffic light identification code. For example, when a #1 vehicle passes through a t-junction, the a-junction signal lamp passing through the t-junction will enter the a-junction signal lamp identification code into the #1 last-pass signal lamp cache corresponding to the #1 vehicle, delete the other signal lamp identification codes previously in the #1 last-pass signal lamp cache, and when the B-junction signal lamp passes through the t-junction, the B-junction signal lamp identification code will be entered into the #1 last-pass signal lamp cache corresponding to the #1 vehicle, and delete the a-junction signal lamp identification code originally entered in the #1 last-pass signal lamp cache.
The waiting vehicle cache is used for recording the waiting vehicles under the corresponding signal lamps, and if a plurality of waiting vehicles exist, the identification codes of the waiting vehicles are sequentially arranged in the waiting vehicle cache according to the arrival time sequence.
The signal lamp identification code is usually a signal lamp number, and the I P address of the signal lamp can also be used as the signal identification code. The vehicle identification code is typically a beacon number placed on the vehicle.
The underground vehicles have priorities, generally the priorities of the vehicles are commanded to be higher than those of people-carrying vehicles, and the priorities of the people-carrying vehicles are higher than those of freight vehicles, so a vehicle priority database needs to be configured.
The signal lamps also have priority, and generally the uplink signal lamps are larger than the downlink signal lamps, or the priority sequence is arranged on the signal lamps (for example, the signal lamp at the A port is larger than the signal lamp at the B port, and the signal lamp at the B port is larger than the signal lamp at the C port), so the signal lamp priority database is also configured.
The mine traffic controller of the invention controls the signal lamps of the vehicles arriving at the intersection through the following steps:
and the mine traffic controller judges the number of signal lamps in a lamp group where the current signal lamp is located according to the signal lamp group database when the current vehicle arrives at the current signal lamp, if the number of the signal lamps is 1, the mine traffic controller executes the step of controlling the signal lamps of the broken road, and if the number of the signal lamps is more than 1, the mine traffic controller executes the step of controlling the signal lamps of the intersection.
S100 broken-end road signal lamp control step
When the current vehicle reaches the vicinity of the broken-end intersection signal lamp, the mine traffic controller further judges whether the current signal lamp is green or red, if the current signal lamp is red, the situation that the vehicle has driven into the broken-end road is shown, the current vehicle enters a wrong lane to wait, the current vehicle identification code is recorded at the tail end of the to-be-driven vehicle cache of the current signal lamp until the mine traffic controller detects that the first-ranked vehicle in the to-be-driven cache under the current signal lamp passes through the current signal lamp again, the situation that the vehicle drives out the broken-end road is shown, the current signal lamp is set as green, the first-ranked vehicle identification code is removed from the to-be-driven vehicle cache of the current signal lamp, and at the moment, a new first vehicle in the to-be-driven vehicle cache of the current signal lamp enters the broken-end ranking road; if the current vehicle directly enters the head-off road, the traffic controller sets the current signal lamp as a red lamp after knowing that the current vehicle passes through the current signal lamp, and records the identification code of the current vehicle into the to-be-driven vehicle cache of the current signal lamp.
S200 intersection processing step
When the vehicle reaches the position near the intersection signal lamp, the mine traffic controller further judges whether the current signal lamp is a green lamp or a red lamp, and if the current signal lamp is a green lamp, the mine traffic controller executes the intersection green lamp processing step; and if the current signal lamp is a red lamp, the mine traffic controller executes the red lamp processing step of the intersection.
S210 intersection green light processing step
If the current signal lamp is a green lamp, the mine traffic controller further judges whether a green lamp is arranged under the same lamp group, if the green lamp is arranged under the same lamp group, the mine traffic controller executes the step of processing multiple green lamps at the intersection, and if only the current signal lamp is a green lamp under the same lamp group, the mine traffic controller executes the step of processing single green lamp at the intersection.
S211 intersection multiple green light processing step
If the same lamp group has green lamps, the mine traffic controller further judges whether vehicles arrive at the same time under the green lamps of the same lamp group, if the vehicles arrive at the same time, the mine traffic controller executes the steps of processing multiple vehicles with multiple green lamps at the intersection, and if the vehicles arrive only under the current signal lamp in the multiple green lamps of the lamp group, the mine traffic controller executes the steps of processing the multiple vehicles with multiple green lamps at the intersection.
S211/1 intersection multi-green-light multi-vehicle processing step
If a plurality of green lights under the light group simultaneously arrive at vehicles, the mine traffic controller compares the priority of which vehicle in the vehicles simultaneously arrives at the highest priority according to the priority data of the vehicles, keeps the green light of the signal light corresponding to the vehicle with the highest priority unchanged, enables the vehicle with the highest priority to pass, records the signal light identification code of the green light into the last-time passing signal light cache of the vehicle with the highest priority, records the vehicle identification code with the highest priority into the tail end of the pending vehicle cache of the signal light with the green light, sets the other signal lights of the same light group as the green light as red lights, and records the vehicle identification codes of the pending vehicles under each red light under the light group into the pending vehicle cache of the corresponding signal light; if the priority of each simultaneously arriving vehicle is the same, the mine traffic controller further judges which priority is the highest in the green signal lamps according to the signal lamp priority database, the mine traffic controller keeps the green lamp of the signal lamp with the high priority unchanged to enable the corresponding vehicle to pass, the signal lamp with the highest priority is recorded into the last passing signal lamp cache of the current passing vehicle, the current passing vehicle identification code is recorded into the tail end of the waiting vehicle cache of the signal lamp with the highest priority, other signal lamps with the green lamp under the same lamp group are red lamps, the corresponding arriving vehicle is enabled to wait in a lane crossing, and the waiting vehicle identification code is recorded into the waiting vehicle cache of each corresponding signal lamp which is newly the red lamp.
S211/2 intersection multi-green light single vehicle processing step
If only one of the green lights under the light group reaches the vehicle, the mine traffic controller keeps the current signal light unchanged, the current vehicle passes, the current signal light is recorded into the last passing signal light cache of the current vehicle, meanwhile, the current vehicle identification code is recorded into the tail of the waiting vehicle cache of the current signal light, and other signal lights which are green lights in the same light group are set to be red lights.
S212 intersection single green light processing step
If the vehicle reaches the green state of the signal lamp and only one green lamp is under the lamp group, the vehicle-following running is indicated, the mine traffic controller keeps the current signal lamp unchanged, the current vehicle passes, the current signal lamp identification code is recorded into the last-time passing signal lamp cache of the current vehicle, and meanwhile, the current vehicle identification code is recorded into the tail of the waiting vehicle cache of the current signal lamp.
S220 the intersection red light processing step is
If the current signal lamp is red, the mine traffic controller inquires whether the last-time passing signal lamp identification code exists in the last-time passing signal lamp cache of the current vehicle, if the last-time passing signal lamp identification code does not exist, the fact that the vehicle firstly arrives under the signal lamp is indicated, the mine traffic controller records the current signal lamp identification code into the last-time passing signal lamp cache of the current vehicle, and simultaneously records the current vehicle identification code into the tail of the to-be-driven vehicle cache of the current signal lamp; if the identification code of the signal lamp passing last time exists, the mine traffic controller judges whether the current signal lamp and the signal lamp passing last time are in the same lamp group according to the signal lamp group database, if the current signal lamp and the signal lamp passing last time are in the same lamp group, the mine traffic controller executes the step of processing red lamps and red lamps in the same lamp group in the crossroad, and if the current signal lamp and the signal lamp passing last time are not in the same lamp group, the mine traffic controller executes the step of processing non-different lamp groups in the crossroad.
S221 intersection red light and lamp group processing step
If the signal lamp which is currently red and the signal lamp which is passed by the current vehicle last time are the same lamp group, the fact that the vehicle goes out of the lamp group is indicated (namely the vehicle passes through the intersection), the mine traffic controller removes the current vehicle from the vehicle cache to be driven of the signal lamp which is passed by the current vehicle last time, and judges whether other vehicles to be driven exist under the signal lamp which is passed by the current vehicle last time. If other vehicles to be driven exist, the situation that a following vehicle exists behind the current vehicle is shown, and the state of the current signal lamp is kept unchanged by the mine traffic controller.
