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.

The train operation control method based on low frequency communication according to the present invention is described below with reference to fig. 1 and fig. 2, where an execution subject of the train operation control method may be a controller of a current train, or a cloud, or an edge server, and the train operation control method is applied to an urban rail transit system

In the rail transit system, the train carries out safety protection calculation according to the current position of the train and the positions of surrounding trains, and controls the running state of the train.

As shown in fig. 1, the train operation control method based on low frequency communication according to the present invention includes steps 110 to 130.

And step 110, sending a low-frequency signal to the target train by the current train through the low-frequency communication link, and receiving the low-frequency signal sent by the target train by the current train.

The low-frequency signal transmitted by the target train is a radio wave signal with a frequency band from tens KHz to hundreds KHz, and the wavelength of the radio wave signal ranges from ten kilometers to one kilometer. The frequency of the low-frequency signal is low, and hundreds of kilometers of transmission in the tunnel can be guaranteed without setting a relay.

The target train is a train around the current train, and may be a train on a running track of the current train or a train having a collision risk with the current train.

It should be noted that the low-frequency signal sent by the target train to the current train carries the position information of the target train, and the low-frequency signal sent by the current train to the target train also carries the position information of the current train.

The low-frequency communication link is a physical channel for communication between the current train and the target train, and a transmission medium of the low-frequency communication link is a low-frequency signal transmitted by the current train or the target train.

And step 120, obtaining the target position of the target train based on the low-frequency signal.

In this embodiment, the low-frequency signal carries the position information of the target train, and the target position of the target train can be obtained according to the low-frequency signal.

And the target position of the target train is the current position of the target train.

It can be understood that the low-frequency signal is transmitted between the low-frequency communication links, and the current train and the target train in the same low-frequency communication link can acquire the low-frequency signal sent by the opposite end, so as to obtain the position information of the opposite end.

In specific implementation, the low-frequency signal containing the target position sent by the target train only comprises position information, and the current train is combined with the position of the target train to control and adjust the running state.

And step 130, controlling the running state of the current train based on the target position and by combining the current position and the running parameters of the current train.

The target position is the current position of the target train, and the current position is the current position of the current train.

In this embodiment, the operation parameters of the current train include information such as the operation speed, the operation direction, the operation plan, and the operation track of the current train.

It will be appreciated that based on the target location, the current location and the operating parameters of the current train, information can be obtained about the route followed by the current train, the locations that may be reached and the times at which the respective locations were reached.

And based on the target position, combining the current position and the operation parameters of the current train to obtain information about the route, the positions possibly reached and the time when the current train arrives at each position, wherein the route is driven after the current train, and the operation state of the current train is controlled to avoid the condition that the current train collides with the target train.

For example, when the distance between the target position and the current position is long, the current train does not collide with the target train when running for a certain period of time according to the current running state, and the current train can be controlled to run according to the current running state.

For example, when the distance between the target position and the current position is short, the current train may collide with the target train when the current train travels for a certain period of time according to the current operation state, and the braking of the current train may be controlled.

The inventor researches a large number of communication faults of trains, and finds that a large part of reasons of communication faults are that trains are communicated through high-frequency signals, particularly when the trains are in a tunnel environment, due to the influence of tunnel humidity and metal components or carbon fibers in the tunnel, the communication strength of the high-frequency signals is reduced in the complex environment, the trains cannot timely and accurately acquire position information of other trains, the trains are braked too early, and the operation efficiency is reduced.

On the basis of discovering above-mentioned technical problem, the inventor passes through the information of transmission between the train and classifies, passes through low frequency signal transmission with the positional information of train, utilizes the characteristics that low frequency signal penetrability is good, and difficult decay for the train can in time accurately acquire the positional information of other trains under the complex environment.

It should be noted that the low-frequency signal in the present invention only transmits the location information of the train to the train, and other communication information with low real-time requirement of the train to the train can be transmitted by other communication methods.

In the related technology, the combination of low-frequency signals and high-frequency signals is adopted, and the train distance is periodically measured, and the frequency of the mentioned low-frequency signals needs to be relayed when used in a tunnel.

The invention transmits the position information through the low-frequency signal, has simple communication process, realizes the timely and accurate acquisition of the position information of the train workshop, simultaneously realizes continuous communication without relay, is beneficial to reducing time delay and improving the stability of the system.

It should be noted that the related art uses a combination of a low frequency signal and a high frequency signal, and aims to transmit a plurality of kinds of information including location information of a train at the same time, whereas the present invention receives a low frequency signal, and aims to transmit only location information of a train.

According to the train operation control method based on low-frequency communication provided by the invention, the position information of the train workshop is acquired by receiving the low-frequency signal, the defect that the position information of the train workshop cannot be timely and accurately acquired in a complex environment in the prior art is overcome, the current train operation state is controlled according to the position information of the train workshop, the train operation safety is improved, and the train operation efficiency is ensured.

In some embodiments, step 110 comprises: establishing a low-frequency communication link based on the low-frequency transmitting power of the current train and the target train; sending a low-frequency signal to a target train by a current train through a low-frequency communication link; and acquiring a low-frequency signal sent by a target train in a target range by the current train through the low-frequency communication link.

The low frequency transmit power refers to the energy in a given low frequency band, and has two measurement criteria, power (W) and gain (dBm).

The low-frequency transmitting power represents the signal intensity of low-frequency signals transmitted by the current train and the target train, and a low-frequency communication link is established based on the low-frequency transmitting power of the current train and the target train, so that the low-frequency signals are effectively transmitted between the low-frequency communication links.

The low-frequency transmitting power of the current train is matched with that of the target train, the current train and the target train are in the same low-frequency communication link, and the low-frequency signal sent by the opposite terminal can be obtained, so that the position information of the opposite terminal is obtained.

In the embodiment, the interference resistance degree of the low-frequency signals sent by the current train and the target train can be improved by adjusting the low-frequency transmitting power of the current train and the target train.

It can be understood that the low-frequency signal refers to a radio wave signal with a frequency band from tens of KHz to hundreds of KHz, and the wavelength range of the radio wave signal is from ten kilometers to one kilometer.

The target range refers to a range within which the current train can receive effective low-frequency signals, that is, the range of all positions within which the current train can transmit effective low-frequency signals.

Based on the low-frequency transmitting power of the current train and the target train, a low-frequency communication link with high reliability is established, low-frequency signals are received in a target range, and the position information of the surrounding trains is timely and accurately acquired.

After the low-frequency communication link is established, the current train sends a low-frequency signal to the target train through the low-frequency communication link, and meanwhile, the current train obtains and receives the low-frequency signal sent by the target train in the target range through the low-frequency communication link.

In some embodiments, the train operation control method further includes: and receiving or transmitting a low-frequency signal to the target train through the low-frequency communication link, wherein the low-frequency signal only comprises the position information.

It can be understood that the low-frequency signal carrying the position information is transmitted between the low-frequency communication links, and can be sent to the current train by the target train, or sent to the target train by the current train, and both ends can receive the low-frequency signal sent by the opposite end, so as to obtain the position information of the opposite end.

The current train sends a low-frequency signal to the target train through a low-frequency communication link, and then reports the position of the current train to the target train, so that reference is provided for the target train to control the running state of the train.

For example, when the current train is about to reach the target position of the target train, the low-frequency communication link is used for sending a low-frequency signal reporting the position of the target train to the target train, and the target train adjusts the running state according to the low-frequency signal and leaves the current target position, so that the two trains are prevented from approaching abnormally.

In some embodiments, the low-frequency communication link is established by utilizing the characteristic of good penetrability of low-frequency communication without relay processing.

At the low frequency signal of low frequency communication link transmission, low frequency signal frequency is lower, and the wavelength range is long, and when moving in the tunnel, the penetrability is strong, need not to set up the relay, also can be in the tunnel barrier-free transmission position information, need not set up equipment such as relay station again in the complex environment in tunnel.

The communication is carried out through the established low-frequency communication link, the relay processing is not needed, the applicability is good in the urban rail transit system with more underground tunnels, the relay is not needed, the train operation safety is improved, and meanwhile, the communication cost is reduced.

In some embodiments, the location information transmitted by the current train constitutes one of the data sources from which other trains acquire the low frequency signals of the surrounding trains.

It can be understood that the current train can not only establish a low-frequency communication link with the target train, but also other trains within the target range can transmit the position information by establishing the low-frequency communication link.

In this embodiment, the position information sent by the current train may also be acquired by other trains, and the position information sent by the current train belongs to one of data sources for acquiring the low-frequency signals of the trains around by other trains, that is, in a certain range, the train sends and receives the low-frequency signals, which is a many-to-many mode.

When the current train can send the current position to a plurality of other trains, the other trains also receive the low-frequency signals of a plurality of surrounding trains.

In some embodiments, step 130 comprises: calculating the position distance between the target train and the current train according to the target position and the current position; calculating the target time when the current train reaches the target position according to the position distance and the operation parameters of the current train; and controlling the running state of the current train based on the target time.

And calculating the target time when the current train reaches the target position according to the position distance and the operation parameters of the current train, wherein the operation parameters of the current train comprise information such as the operation speed, the operation direction, the operation plan and the operation track of the current train.

In this step, the target time is a time point when the current train reaches the target position of the target train according to the distance between the running positions of the running speed.

And controlling the running state of the current train based on the target time when the current train reaches the target position of the target train according to the running speed.

That is, before the current train reaches the target position where the target train is located according to the running speed, the target train already leaves the target position, and the two trains do not get close abnormally.

The current train can timely and accurately acquire the position information of the trains around by receiving the low-frequency signals, and the running state of the current train is controlled by calculating the target moment based on the position information, so that the running safety of the train is improved, and the running efficiency of the train line is ensured.

And secondly, controlling the current train brake.

In this embodiment, it is determined that the target train has not left the target location before the target time, and the current train braking is controlled.

That is, before the current train reaches the target position where the target train is located according to the running speed, the target train does not leave the target position, and if the current train continues to run, two trains may be abnormally close to each other.

It can be understood that the current train receives the low-frequency signal, and timely acquires the position information of the trains around, so that the abnormal approach of the current train and the target train is avoided, and the operation safety of the train is improved, and the operation efficiency of each train including the current train in the rail transit system is ensured.

In the embodiment, the target train is determined not to leave the target position before the target time, the current train can be controlled to brake, the current train can also be controlled to send a low-frequency signal to the target train, the target train adjusts the running state according to the received low-frequency signal, and leaves the current target position, so that the two trains are prevented from being abnormally close.
