Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The antenna lift control system that this application embodiment provided includes: an antenna 10, a lifter 20, a height controller 30, and a main controller 40.
Referring to fig. 1, it can be seen that in the antenna lifting control system provided in the embodiment of the present application, the antenna 10 is fixedly connected to the lifter 20; the lifter 20 is in signal connection with the height controller 30; the height controller 30 is in signal connection with the main controller 40.
Specifically, the altitude controller 30 and the main controller 40 may be connected by a hard wire or a Controller Area Network (CAN) bus as long as signal transmission is possible. And the device adopts hard wire connection, so that the accuracy is higher and the maintenance is easy. And the CAN bus is adopted for connection, so that the signal transmission speed is high, the occupied space of the wiring harness is saved, and the anti-interference capability is high. The lifter 20 comprises a lifting mechanical arm which is simple in structure, easy to control and low in cost.
The work flow of the system is as follows: the main controller 40 marks a first curve on the driving route, and confirms the position of the vehicle according to the map; comparing the location to a driving route; sending a first instruction to the height controller 30 in a case where the comparison result is that the front of the vehicle is a first curve; after receiving the first instruction, the height controller 30 controls the lifter 20 to drive the antenna 10 to ascend; the radius of the first curve is smaller than the set radius. The set radius is a critical radius at which the antenna and the track beam do not collide with the collision. Of course, it is preferable to set the radius larger than the critical radius. For example, when the radius of the first curve is 50 meters, the bottom end of the antenna is slightly contacted with the top end of the track beam to collide; the set radius may be determined to be between 55 m and 60 m, and it is ensured that the antenna does not collide with the track beam.
The following lists a first workflow of the antenna elevation control system provided in the embodiment of the present application:
referring to fig. 2, the first workflow includes steps S10 to S50. Specifically, the method comprises the following steps:
step S10: the main controller marks a first curve on the driving route and confirms the position of the vehicle according to the map.
Step S20: the location is compared to the driving route.
Step S30: whether the result of the comparison is that the front of the vehicle is the first curve. If so, go to step S40; if not, return is made to step S10.
Step S40: a first instruction is sent to the height controller.
Step S50: and after the height controller receives the first instruction, the height controller controls the lifter to drive the antenna to ascend.
As can be seen from the above, the antenna elevation control system provided in the embodiment of the present application compares the pre-stored driving route with the current position of the vehicle, and controls the antenna to ascend when the vehicle is about to enter the first curve. So that the antenna does not collide with the track beam after driving into the first bend, and the safety of the antenna is ensured.
Alternatively, the travel route may be a fixed route pattern preset for a dispatch station where the vehicle is located, the fixed route pattern being prestored in the main controller 40. And the main controller 40 marks the first curve on the driving route in advance, and after the vehicle position is determined, compared with the driving route, it can be quickly determined whether the front of the vehicle is the first curve, so that an instruction for controlling the antenna to ascend can be given conveniently, and the calculation flow can be saved.
Further, in the case where the comparison result is that the vehicle ahead is a first curve, sending a first instruction to the height controller 30 includes: confirming the distance between the vehicle and a first curve when the comparison result shows that the front of the vehicle is the first curve; in the case where it is confirmed that the distance of the vehicle from the first curve is a first mileage, a first instruction is sent to the height controller 30. Since it takes a certain time for the lifter 20 to lift the antenna 10, the antenna 10 needs to be lifted up before the vehicle enters the first curve. But also not to control the antenna 10 to rise at a particular distance from the first bend in order to avoid that the antenna 10 is unable to receive signals from ground transponders for a long time. Therefore, after the vehicle is away from the first curve for the first mileage, the antenna 10 is controlled to rise, so that the antenna 10 can be ensured to rise in time, and the antenna 10 can be prevented from receiving signals of the ground transponder for a long time. The first mileage is set to ensure that the antenna 10 is raised before the vehicle enters the first curve. The specific value range may be determined according to the traveling speed of the vehicle and the time required for the antenna 10 to ascend.
Alternatively, for example, the speed of the vehicle is 80 kilometers per hour, and the lifter 20 takes ten seconds to twenty seconds to lift the antenna 10. The value range of the first mileage may be: the first mileage is less than or equal to 1 kilometer and less than or equal to 2 kilometers. The main controller 40 sends a first instruction to the height controller 30 at a distance of 1 km to 2 km before the vehicle enters the first curve, which may cause the antenna 10 to have risen before the vehicle enters the first curve. Avoiding that the vehicle has driven into the first bend, with the antenna 10 in a rising or non-rising state, can also result in the antenna 10 colliding with the track beam 120. In addition, setting the above value range does not cause the antenna 10 to rise too early, so that the antenna 10 cannot receive the signal of the ground transponder for a long time.
Referring to fig. 3, a second working procedure of the antenna elevating control system according to the embodiment of the present application is described below. The method specifically comprises the following steps:
step S10: the main controller marks a first curve on the driving route and confirms the position of the vehicle according to the map.
Step S20: the location is compared to the driving route.
Step S30: whether the result of the comparison is that the front of the vehicle is the first curve. If so, go to step S40; if not, return is made to step S10.
Step S40: the distance between the vehicle and the first curve is identified.
Step S50: it is determined whether a distance between the vehicle and the first curve is less than a first mileage. If so, go to step S60; if not, return is made to step S40.
Step S60: a first instruction is sent to the height controller.
Step S70: and after the height controller receives the first instruction, the height controller controls the lifter to drive the antenna to ascend.
Therefore, the antenna lifting control system provided by the embodiment of the application compares the position of the vehicle with the driving route, confirms that the vehicle is about to drive into the curve with a smaller radius, and controls the antenna to lift under the condition of the first mileage distance from the first curve. Therefore, the antenna can be ensured to rise before the vehicle enters the first curve, the situation that the antenna and the track beam collide after the vehicle enters the curve is avoided, and the antenna is prevented from being damaged.
Further, the system further comprises: sending a second command to the height controller 30 when the comparison result indicates that the front of the vehicle is a second curve after the antenna 10 is raised; after receiving the second instruction, the height controller 30 controls the lifter 20 to drive the antenna 10 to descend; the radius of the second bend is larger than or equal to the set radius. It should be noted that the radius of the second curve is greater than or equal to the set radius, including the case where the second curve is a curve with a larger diameter and the case where the second curve is a straight line. That is, after comparing the driving route with the position of the vehicle, it is determined that the vehicle has left a curve with a smaller radius and the front side is a curve with a larger diameter or a straight road, the antenna is controlled to descend, so that the antenna can normally receive the information of the ground transponder, and the antenna is prevented from not receiving the information of the ground transponder for a long time.
Optionally, when the comparison result is that the front of the vehicle is a second curve, sending a second instruction to the height controller 30 includes: confirming the distance between the vehicle and the first curve when the comparison result shows that the front of the vehicle is the second curve; in the case where it is confirmed that the distance between the vehicle and the first curve is the second mileage, a second instruction is sent to the height controller 30.
It is confirmed that the vehicle has traveled off the first curve and has traveled a certain distance away from the first curve, and the antenna 10 is controlled to descend again. On the one hand, sufficient time is reserved for the acknowledgement of the track 110 information; on the other hand, it is avoided that on the track 110 section of successive curves, the vehicle has just traveled a first curve, followed by a second first curve within a short distance. Then the following situation occurs: the vehicle is controlled to descend the antenna 10 immediately after exiting one first bend, and then the vehicle enters a second first bend several hundred meters later, and the antenna 10 needs to be controlled to ascend immediately. When it is confirmed that the vehicle has traveled away from the first curve and has traveled away from the first curve by a predetermined distance, the antenna 10 is controlled to descend, and the antenna 10 is prevented from entering the ascending state from the ascending state to the descending state. In particular, in the case of a faster vehicle speed, it is possible that the antenna 10 may not have time to rise and the vehicle has already traveled into the second, first bend, which may result in a collision between the antenna 10 and the track beam 120.
The range of the second mileage may be determined according to the average traveling speed of the vehicle and the time required for the antenna 10 to descend. The time required for the antenna 10 to descend is ten seconds to twenty seconds at a speed of the vehicle of 100 kilometers per hour. Optionally, the value range of the second mileage is: the second mileage is less than or equal to 0.5 kilometer and less than or equal to 1 kilometer. Setting the value range can make the following contributions for the vehicle with the vehicle speed of 100 kilometers per hour: on the one hand, sufficient time is reserved for the acknowledgement of the track 110 information; on the other hand, on the track 110 section of the continuous curve, the vehicle just drives out a first curve, and a second first curve occurs after about 1 kilometer or even hundreds of meters. At this time, the vehicle immediately controls the antenna 10 to descend after driving out of one first curve, and then the vehicle drives into a second first curve several hundred meters later, and the antenna 10 needs to be immediately controlled to ascend. Setting the value range for the second range can avoid that the antenna 10 just enters the ascending state from the ascending state to the descending state. In particular, in the case of a faster vehicle speed, it is possible that the antenna 10 may not have time to rise and the vehicle has already traveled into the second, first bend, which may result in a collision between the antenna 10 and the track beam 120.
Specifically, referring to fig. 7, a third working flow of the antenna elevating control system provided in the embodiment of the present application is as follows:
the third workflow includes steps S10 to S120, wherein steps S10 to S70 are the same as steps S10 to S70 in the second workflow, and are not described again. Steps S80 to S120 are detailed below.
Step S80: whether the result of the comparison is that the front of the vehicle is the second curve. If so, go to step S90; if not, return is made to step S20.
Step S90: the distance between the vehicle and the first curve is identified. The main controller 40 calculates a distance between the tail of the vehicle and the first curve according to the position of the vehicle and the driving route. That is, the distance from the first curve when the vehicle continues to travel forward after leaving the first curve.
Step S100: and judging whether the distance between the vehicle and the first curve is greater than the second mileage. If yes, go to step S110; if not, return is made to step S90.
Step S110: a second instruction is sent to the height controller.
Step S120: and after the height controller receives the second instruction, the height controller controls the lifter to drive the antenna to descend.
Further to avoid a signal system failure, the main controller 40 sends an error command or fails to send a command to the height controller 30, resulting in an abnormal rise or fall of the antenna. In the case of a signal system failure or an abnormality in communication between the height controller 30 and the main controller 40, the height controller 30 controls the antenna to ascend. That is, two cases are included, one case being: in the case that the communication between the main controller 40 and the height controller 30 is abnormal, the height controller 30 controls the lifter 20 to lift the antenna 10. The other situation is as follows: in the case of a signal system failure and the main controller 40 and the height controller 30 are communicating normally, the main controller 40 sends a first instruction to the height controller 30; after receiving the first instruction, the height controller 30 controls the lifter 20 to drive the antenna 10 to ascend. The signal failure includes: an Automatic Train Operation (ATO) fault or an Automatic Train Protection (ATP) fault, and the like, but the main controller 40 may also communicate with the height controller 30, and the main controller 40 is set to default to send the first command to the height controller 30.
That is, the antenna 10 is controlled to ascend whenever the signal system fails regardless of whether the main controller 40 and the height controller 30 can normally communicate. It is avoided that in case of a signal system failure the vehicle has driven into the first bend while the antenna 10 is still in a non-raised state, resulting in a collision of the antenna 10 with the track beam 120.
Still further, the antenna elevation control system further comprises a distance sensor. The distance sensor is arranged on the antenna 10, and the distance sensor is in signal connection with the main controller 40.
After the antenna 10 ascends and the vehicle enters the first curve, the main controller 40 acquires a distance value monitored by the distance sensor; the distance value is the distance between the antenna 10 and the track beam 120; sending a second command to the height controller 30 when it is determined that the distance value is greater than a third set value; after receiving the second instruction, the height controller 30 controls the lifter 20 to drive the antenna 10 to descend. The third setting value may be, for example, 30 cm, and the distance between the antenna 10 and the track beam 120 is relatively long, so that the antenna does not collide with the track beam even after descending, and thus the descending of the antenna can be controlled. The height of the drop may be, for example, between 20 cm and 25 cm.
That is, when it is detected that the height interval between the antenna 10 and the track beam 120 is relatively large and there is a space for the antenna 10 to descend after the antenna 10 ascends and the vehicle enters the first curve, the antenna 10 is controlled to descend. Due to terrain or different track 110 models, some track beams 120 may be relatively low, while some track beams 120 may be relatively high. Thus uniformly controlling the antenna 10 to ascend before entering the first turn.
After entering the first bend, the distance between the top of the track beam 120 and the antenna 10 is determined to be relatively large by the distance sensor, that is, the track beam 120 is of a relatively low model, and at this time, the antenna 10 can be controlled to descend, so that the antenna 10 can normally receive signals of ground transponders. Especially for the case that the first bend is relatively long, the antenna 10 receives the signal of the ground transponder, which is beneficial to correcting the vehicle position and calibrating mileage.
It is emphasized that the specific height of the antenna to be raised and lowered is determined by the distance between the top end of the actual track beam and the bottom end of the antenna, and the distances between the antennas of different vehicles and track beams of different models are different, so long as it is ensured that the bottom end of the antenna is higher than the top end of the track beam after entering the first bend. And ensuring that the vehicle drives away from the first bend, and after the antenna is descended, receiving a ground transponder signal.
Those skilled in the art will appreciate that the main controller 40 may be a vehicle-mounted controller (VOBC), and the antenna may be a BTM antenna; the height controller may be any one of an Industrial Personal Computer (IPC), a Programmable Logic Controller (PLC), or a Distributed Control System (DCS).
In addition, the antenna lifting control system provided by the embodiment of the application is used on vehicles, and is particularly suitable for vehicles running on rails, such as rail trains like subways, high-speed rails, light rails and motor cars. Therefore, the embodiment of the present application also provides a vehicle 100, which includes the antenna lifting control system provided in any embodiment of the present application. Referring to fig. 4 to 6, fig. 4 shows that the antenna 10 is installed at the bottom of the vehicle 100 at a height from the ground on which the track 110 is laid, with reference to the information that the antenna 10 can clearly receive the ground transponder. Fig. 5 shows the position of the antenna 10 when the vehicle 100 is traveling in the first curve, and the vehicle 100 is traveling along the track beam 120.
