All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the application field of rail transit, diseases generated by a turnout mechanical mechanism can be obtained and fault processing is realized based on sound signals, however, the normal switching time of the turnout is longer, generally 3.4S, 5.8S and the like, the maximum time can reach 15S or 30S, the calculated amount is very large by using a common processing means, and the calculated pressure is very large for a processor.
The embodiment of the invention provides a processing method of switch conversion sound, which considers that switch monitoring equipment collects sound and current data at the same time, and the current data can represent different stages of switch conversion, so that the sound data is segmented by using the current data, and then the characteristics of the sound data are calculated by different methods by subdividing the segmented data, so that a large amount of data can be changed into a plurality of segments of small data, each segment represents the dynamic characteristics of one mechanical equipment, and accurate fault positioning can be realized.

s2, extracting the current curve, and performing data processing on the current curve to obtain a curve segment point position set;
and S3, mapping the curve segmentation point position set to the sound curve to obtain a segmentation processing result of the sound curve.
Specifically, as shown in fig. 2, the synchronous acquisition module acquires the sound data and the current data of the turnout synchronously, wherein the sound data is acquired independently by adopting a microphone sensor, the current data is acquired independently by adopting a hall current sensor, the acquisition point is positioned on the X1 for the alternating current switch machine, and the acquisition point is positioned on the X4 for the direct current switch machine. The synchronous acquisition module acquires current and sound data simultaneously by using a synchronous acquisition technology, so that the current acquisition point and the sound data acquisition point are ensured to be acquired simultaneously; the main control module can control the collection of current and sound and perform preliminary processing on the data; the master control module is connected with the server and sends the acquired data to the server; the communication module is used for transmitting the acquired data to a processor or a server.

The mechanical parts operate according to the switch switching time sequence, and different mechanical equipment works at different stages. The conversion process is as follows:
And in the unlocking process, the turnout is locked by the outer locking device under normal conditions. When the motor rotates during conversion, the speed reducer converts high rotation speed into large torque, and provides moving force for the locking rod, so that the locking hook moves, and when the locking hook reaches a certain position, the locking hook is released, and the turnout is unlocked. Unlocking is that the automatic switch is switched to a movable contact to switch on a circuit which is reversely moved;
in the rotating process, the motor outputs force to drive the action connecting rod to act, and the switch rail moves on the slide plate;

Simultaneously, the locking rod moves, and when the maximum locking amount is reached, the turnout is locked; after the turnout is locked, the locking rod drives the other automatic switch to switch, the three-phase power supply is cut off, and the motor stops rotating.
Therefore, the conversion current is collected in the whole conversion process as shown in fig. 3, and the current value is smaller at the point A and before because the turnout is in a locking state, the current is the representation current; the current becomes large after the point A, the motor starts to rotate, the turnout starts to unlock, and the current reaches the maximum value after the point B; after the turnout from the point B to the point C is unlocked, the turnout starts to rotate; the point rail is driven to move by the action rod of the point switch from the point C to the point D; at the point D, the switch rail rotates in place and is closely attached to the stock rail, the locking rod drives the automatic switch to switch, and three-phase current is cut off; the delay stage of the indoor relay is from the point D to the point E. The corresponding sound waveforms for the entire conversion process are shown in fig. 4.

setting a second current threshold value, and acquiring a first acquisition point which is smaller than the second current threshold value from the maximum value point to the last acquisition point in the current curve, and recording the first acquisition point as a stop value point; wherein the second current threshold is greater than the first current threshold;
Calculating an average value of all the acquisition points from the starting value point to the stopping value point, setting the average value as a third current threshold value, acquiring the first acquisition point which is smaller than the third current threshold value from the starting value point to the stopping value point, and recording the first acquisition point as a conversion value point;
counting the total acquisition points from the conversion value point to the stop value point, and segmenting the total acquisition points to obtain a plurality of segmentation points;
