Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a signal device fault diagnosis method according to an embodiment of the present invention. As shown in fig. 1, the method includes: acquiring railway operation data in real time; carrying out simulation operation according to the railway operation data and the interlocking table; and determining the fault reason of the signal equipment according to the simulation operation result and the acquired railway operation data.
The data can be transmitted in various existing data transmission modes in the process of acquiring the railway operation data in real time. For example, a wired communication method and a wireless communication method.
The railway operation data comprises data such as equipment signal switching value, power supply panel voltage, track phase angle, frequency shift transmitter voltage, frequency shift transmitter current, frequency shift receiver voltage, frequency shift transmitter frequency, frequency shift receiver frequency, turnout indication voltage, signal machine outgoing line current and the like.
The embodiment of the invention provides a specific signal equipment fault diagnosis method, and a flow chart of the method is shown in fig. 2.
Specifically, the method comprises the steps of acquiring railway operation data in real time, and taking the time point of abnormal closing of the signal machine as the current time point when the signal machine is abnormally closed. The abnormal turn-off of the traffic signal means that the traffic signal is not in a turn-off state under a specified condition.
Firstly, whether the current time point is in the skylight point is judged. The skylight point refers to the time reserved for construction and maintenance operation without drawing the train operation or adjusting and reducing the train operation in the train operation diagram. If the current time point is in the skylight point, the annunciator is closed to be in a normal working state, and after construction or maintenance is finished, the annunciator starts to work normally.
And under the condition that the current time point is not in the skylight point, judging whether all data in the acquired railway operation data have abnormal phenomena or not, such as whether all switching value interruption phenomena, all analog value interruption phenomena, data exceeding threshold value phenomena or data logic error phenomena occur or not. Specifically, for example, when the overall switching value is completely interrupted, it is determined that the turn-off of the traffic signal is caused by any one or more of the following: system communication problems, switch location/flipping indicate a relay data outage or a power outage of the signaling device power supply system. It is also possible that the switch is not in the loss table, but the switch location/inversion indicates that the relay fault causes the abnormal closing of the signal machine, or a certain signal relay simultaneously sends out two signals of 0 and 1, and then determines the signal relay fault and the like.
And when determining that all the data have no abnormal phenomenon, judging whether the signal machine is closed within a preset time after the train passes. The functions and requirements of the traffic signals vary from one traffic signal type to another. For example, after the train passes through the station signal, the train needs to be shut down immediately, and after the train passes through the shunting signal, the train needs to be shut down after delaying for a preset time, and if the train is shut down immediately, the shunting signal is determined to be shut down abnormally, and at this time, the reason for the abnormal shut down of the shunting signal needs to be further checked to solve the fault. The duration of the preset time can be set according to actual work. For example, we can set the predetermined time to 3s, and determine whether the signal is turned off within 3s after the train passes the signal based on the acquired railway operation data.
In the case where it is determined that the traffic signal is turned off within a predetermined time after the train passes, the current states of all traffic signals except the traffic signal which is normally turned off and the state of the traffic signal at the time point immediately before the current time point are acquired, and it is determined whether or not an abnormality occurs in other traffic signals except the traffic signal which is normally turned off.
And when the current states of all the signalers except the normally closed signalers and the state of the previous time point of the current time point are not abnormal, determining the type of the abnormally closed signalers according to the acquired relevant data about the abnormally closed signalers. The types of general signals include an incoming signal, an outgoing signal, a shunting signal, an incoming and outgoing cum-shunting signal, and the like.
And when the abnormal signal is a shunting signal, determining whether the switching state is changed into the closing state from the lighting state or not according to the current state of the shunting signal and the state of the time point before the current time point, namely whether the switching state is changed from white light to blue light or not.
After the process, the shunting signal machine is determined to be abnormally closed, relevant data related to railway operation are not abnormal, and other signal machines are not abnormal. Further simulation work is then required to determine the cause of the abnormal shut down of the signaler.
Specifically, under the condition that the abnormal closing of the shunting annunciator is determined, simulating according to the current states of all the annunciators except the annunciator which is not normally closed, the state of the previous time point of the current time point and the interlocking table, and determining the simulation states of all turnouts of the approach where the shunting annunciator is located; determining the current states of all turnouts of the route where the shunting signal machine is located at the current time point according to the acquired railway operation data; and comparing the simulation states of all the turnouts with the current state one by one, and determining that the turnout is out of the table to cause abnormal closing of the shunting signal machine when the simulation state of any turnout in all the turnouts is inconsistent with the current state.
When the switch loses the demonstration, can lead to the interlocking relation of switch and semaphore to suffer destruction, and then make the signal of arriving at a station can't open, the signal of shunting that sets up in shunting entry entrance department is normally closed promptly.
By the technical scheme provided by the invention, the abnormal closing of the shunting annunciator caused by the fact that the switch is out of the table can be quickly and accurately determined, and after the staff determines the switch out of the table, the reason that the switch is out of the table is determined, so that the fault that the abnormal closing of the shunting annunciator caused by the switch out of the table can be quickly repaired.
