The embodiment of the application provides a method for detecting train derailment, as shown in fig. 1, comprising the following steps:

s101, acquiring the acceleration information of the current train in real time when the train runs.

Wherein the acceleration information of the train is used for indicating the acceleration of the off-track to which the train is currently subjected.

It should be noted that, when a Field Programmable Gate Array (FPGA) is started, the acceleration information of the current train needs to be acquired in real time. The starting condition of the control module includes, but is not limited to, detecting running speed information of the train in real time through a speed sensor in a server of the train head, and sending the current running speed information to the control module, when the running speed received by the control module is greater than a threshold value, which can be, but is not limited to, 20 kilometers per hour, starting the control module, and obtaining acceleration information of the current train in real time; similarly, a train derailing detection button can be arranged in a train cab, and a driver or a worker can actively start the control module by pressing the button when the train is started and detect whether the train is derailed or not by using the control module. The starting mode of the control module is very diverse and mature, so the control module is not limited here.

It should be noted that the acceleration sensor on the server of the train head detects the acceleration of the current train that is received from the off-track, and the obtained acceleration information of the train head is used as the acceleration information of the current train.

Specifically, when the train runs, the acceleration sensor on the server at the train head detects the acceleration of the current train, which deviates from the track, and sends the acceleration information of the current train to the control module in real time.

And S102, judging whether the current train has a derailment danger or not according to the acceleration information of the train.

Specifically, the acceleration information of the train is collected in real time through an acceleration sensor and is sent to a control unit, the current acceleration information of the train is compared with preset acceleration information, whether the current train is in danger of derailing or not is judged, and if the current train is in danger of derailing, the step S103 is executed.

Optionally, in another embodiment of the present application, an implementation manner of step S102 includes:

and judging whether the acceleration of the deviated track currently suffered by the train is greater than a threshold value.

It should be further noted that, under different running speeds of the train, the threshold corresponding to the acceleration of the off-track is different, for example, if the current running speed of the train is 100 kilometers per hour, then the threshold corresponding to the acceleration of the off-track is 10; if the current running speed of the train is 120 kilometers per hour, the corresponding threshold value of the acceleration deviating from the track is 15; it should be noted that the threshold corresponding to the acceleration of the train deviating from the track at different running speeds is adjustable by the technician, and is not limited to the above numerical values, and the above numerical values are only examples, and the numerical values in practical application are not limited to the above numerical values, and therefore, the present invention is not limited thereto.

Specifically, in the process of train running, firstly determining the running speed of the current train, confirming the running speed of the current train and a threshold corresponding to the acceleration of the corresponding deviated track, and judging whether the acceleration of the deviated track received by the current train is greater than the threshold, if the acceleration of the deviated track received by the current train is greater than the threshold, indicating that the current train has a derailment risk, executing step S103; and if the acceleration of the deviated track currently suffered by the train is judged to be less than or equal to the threshold value, the current train is not in derailment danger.

And S103, sending inquiry information to the server of each compartment.

The way of sending the inquiry information to the server of each car is very diverse and mature, and therefore, the present invention is not limited thereto.

The query information may be sent to the server of each car in sequence, for example, each car is configured by a dial switch, and the first bit of the dial switch is used to configure the current server as the server of the train head or the server of the car, taking an 8-bit dial switch as an example. The first bit of the dial switch of the server for representing the train head can be set to 1; setting a first bit of a dial switch of a server for representing a car to 0; the remaining 7 bits are used to indicate which car's server is the server for the current car. For example, the server for the train head may be denoted as 10001000; the server for the first car may be denoted as 00000001, the server for the second car as 00000010, the server for the third car as 00000011, and so on. The first carriage is a carriage closest to the train head; the second carriage is a carriage which is the second closest to the train head. When it is determined in step S102 that there is a risk of derailment of the current train, the server at the head of the train first sends query information to the server in the first car, and after receiving the feedback information sent by the server in the first car, sends the query information to the server in the second car until the server in the last car is queried.

It is also possible to send the inquiry message according to the priority of each car. Specifically, the priority may be set for each car on the train before the train departs, and the setting of the priority may be, but is not limited to, the priority level being 1, the priority level being 2, the priority level being 3, and the like. For example, dangerous goods are stored in the third carriage of the train, and if the third carriage stores flammable and explosive goods, if the third carriage is derailed, more serious accidents such as explosion and the like can be caused, and more casualties can be caused; the second carriage is a normal passenger carriage; the first car is a freight car, then the first car of the train can be set to a priority of 1; the second car is set to priority 2; the third carriage is set to have a finite level of 3, when it is judged in step S102 that the current train is in danger of derailing, the server at the head of the train first sends inquiry information to the server at the third carriage with the highest priority, and after receiving feedback information sent by the third carriage, sends inquiry information to the server at the second carriage until inquiring the server at the carriage with the lowest priority; in an actual application scenario, the priority of each car may be set, or the priority may be divided according to the passenger level in the car, which is not limited herein.

Specifically, inquiry information is sent to the server of each carriage through a wireless communication module on the server of the train head.

And S104, receiving inquiry information sent by the server of the train head.

Specifically, the inquiry information sent by the server of the train head is received through the wireless communication module on the server on the carriage.

And S105, sending the feedback information to a server of the train head.

The feedback information comprises first feedback information, second feedback information and third feedback information, wherein the first feedback information is used for indicating whether the current carriage has a derailment danger or not and is obtained by judging whether the current carriage has the derailment danger or not according to the acceleration information of the current carriage acquired in real time; the acceleration information of the current carriage is used for indicating the acceleration of the current carriage subjected to the deviation track; the second feedback information is used for indicating whether the current carriage is separated from the previous carriage or not, and is obtained by judging whether the current carriage is separated from the previous carriage or not by using the sound wave module when the current carriage is judged to have the derailment danger; the third feedback information is used for indicating that the real-time position information of the current carriage is obtained by utilizing the positioning module to position the current carriage in real time when the current carriage is judged to be separated from the previous carriage if the current carriage is separated from the previous carriage.

It should be noted that the server of the car starts to determine whether the current car is in danger of derailing after the train starts to run, starts to determine whether the current car is separated from the previous car if the current car is in danger of derailing, and starts to position the current car in real time when the current car is separated from the previous car. After the first feedback information, the second feedback information and the third feedback information are obtained, when the server of the train head sends inquiry information to the current carriage, the first feedback information, the second feedback information and the third feedback information are sent to the server of the train head.

Specifically, the feedback message is added through a wireless communication module on a server of the carriage and sent to a server of the train head.

Optionally, an implementation manner of determining whether the current car has a derailment risk according to the acceleration information of the current car includes:

and judging whether the current acceleration of the current carriage, which deviates from the track, is greater than a threshold value.
