The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
It can be understood that when the turnout is switched, the trolleys at the two ends of the turnout beam are mainly used for bearing the beam body to move and switch, and because the beam body is longer, the guide mechanism is worn to avoid the beam body from deviating, so that the requirement on the synchronism of the two trolleys during the movement is higher.

The following describes a switch trolley synchronous detection method and device according to an embodiment of the application with reference to the accompanying drawings.
First, a method for detecting synchronization of a switch trolley provided in an embodiment of the present application will be described.
Fig. 1 is a schematic flow chart of a switch trolley synchronous detection method according to an embodiment of the present application.
As shown in fig. 1, the switch trolley synchronous detection method includes:
And step 102, determining whether the two turnout trolleys are synchronous or not according to the pulse signals respectively output by the two encoders.
Specifically, according to the switch trolley synchronous detection method provided by the embodiment of the application, the execution main body is the switch trolley synchronous detection device provided by the embodiment of the application, and the device can be configured in any switch system to realize synchronous detection of switch trolleys.
Wherein, two switch trolleys are respectively erected at two ends of the switch beam.
The encoder may be a linear encoder, a rotary encoder, or the like. The encoder can convert the angular displacement or the linear displacement into a digital pulse signal during the operation process.
It can be understood that, taking the rotary encoder as an example, since the rotary encoder outputs a pulse signal every time it rotates a certain angle, the angle of rotation of the rotary encoder in unit time can be determined according to the number of pulses output by the rotary encoder in unit time. Because there is a certain mapping relation between the angle and the displacement, the moving speed can be determined according to the number of pulses output in unit time of the rotary encoder. Similarly, the displacement of the rotary encoder during a period of time can be determined according to the number of pulses output by the rotary encoder during the period of time.
Therefore, in this application embodiment, can install the encoder respectively on two switch dollies to when two switch dollies removed, according to the pulse quantity that two encoders were exported respectively, confirm the speed and the displacement that two switch dollies removed, thereby confirm whether synchronous of two switch dollies.

And 102b, determining that the two turnout trolleys are synchronous when the movement speed and/or displacement of the two turnout trolleys are the same.
Specifically, when the initial positions of the two switch carriages are the same, if the movement speeds and/or displacements of the two switch carriages are determined to be the same according to the pulse signals respectively output by the two encoders, the two switch carriages can be determined to be synchronous.
It should be noted that, in the embodiment of the present application, the performance parameters of the two encoders respectively installed on the two switch trolleys may be the same or different.
If the performance parameters of the two encoders are different, whether the two turnout trolleys are synchronous or not can be determined according to the pulse number contained in the pulse signals respectively output by the two encoders and the performance parameters of the two encoders.
If the performance parameters of the two encoders are the same, whether the two turnout trolleys are synchronous or not can be determined only according to the pulse number contained in the pulse signals respectively output by the two encoders.
That is, step 102 may be implemented by:
and determining whether the two turnout trolleys are synchronous or not according to the pulse number contained in the pulse signals respectively output by the two encoders.
Specifically, if the pulse signals respectively output by the two encoders include equal number of pulses, which indicate that the movement speeds and/or displacements of the two switch carriages are the same, it may be determined that the two switch carriages are synchronized.
In the embodiment of the present application, the number of pulses output by the two encoders is equal, which means that the number of pulses output by the two encoders in a unit time is equal to the total number of pulses output after the encoders start counting.
In addition, in an advantageous implementation form, in order to improve the accuracy of the synchronous detection of the turnout trolleys, two encoders may be respectively disposed on the driven wheels of the two turnout trolleys.
It can be understood that when the switch is performed, the driving wheel of the switch trolley is usually driven by the motor to drive the driven wheel to rotate, so as to bear the movement of the beam body and switch. In this application embodiment, through installing the encoder on the follower of two switch trolleys to whether move synchronous the detecting to two switch trolleys, when having avoided mechanical transmission and action wheel to skid, the error that probably produces has improved the accuracy that detects.
The switch trolley synchronous detection method provided by the embodiment of the application firstly acquires the pulse signals respectively output by the two encoders, wherein the two encoders are respectively positioned on the two switch trolleys, and then determines whether the two switch trolleys are synchronous according to the pulse signals respectively output by the two encoders. From this, realized carrying out real-time detection to the synchronism when two switch platform trucks move, avoided two roof beam body off tracking and the mechanical damage that cause when the platform trucks move asynchronous, improved the security.
Through the analysis, the encoders can be installed on the two turnout trolleys, so that the synchronism of the two turnout trolleys during movement can be detected in real time according to the pulse signals respectively output by the two encoders. In practical applications, when the switch trolley moves, a certain mechanical error is allowed to exist, and the switch trolley synchronous detection method provided by the embodiment of the present application is further described below with reference to fig. 2.

And step 204, determining whether the two turnout trolleys are synchronous or not according to the movement speeds and/or the displacements of the two turnout trolleys and the mechanical error ranges respectively corresponding to the two turnout trolleys.
The detailed implementation process and principle of step 201 may refer to the detailed description of the above embodiments, and are not repeated herein.
During specific implementation, the mechanical error ranges corresponding to the two turnout trolleys respectively can be obtained according to actual conditions, and the pulse number of the two encoders or the movement speed or the displacement error range of the two turnout trolleys are determined according to the mechanical error ranges. Therefore, after pulse signals output by the two encoders are obtained, whether the pulse quantity output by the two encoders or the movement speed or the displacement of the two trolleys are within a preset error range or not can be determined according to the pulse signals, and if the pulse quantity output by the two encoders or the movement speed or the displacement of the two trolleys are within the preset error range, the two turnout trolleys can be determined to be synchronous.
In addition, in this application embodiment, can also show information such as the movement speed, displacement and the synchronism of two switch dollies to the user to make the user in time know the motion condition of two switch dollies, and then control two switch dollies.
That is, after step 204, it may further include:
and displaying the movement speed, the displacement and the synchronism of the two turnout trolleys.
And the synchronism is used for representing whether the two turnout trolleys are synchronous or not. Generally, if the movement speeds and/or displacements of two switch carriages are the same when their initial positions are the same, it can be determined that the two switch carriages are synchronized.
Specifically, a display can be arranged in the turnout trolley synchronous detection device, so that the movement speed, the displacement and the synchronism of the two turnout trolleys are displayed on the display in real time.
It should be noted that, when displaying the moving speed, the displacement and the synchronism of the two switch trolleys, the moving speed, the displacement and the synchronism may be displayed in the form of data, or may be displayed in the form of graphics or any other forms, which is not limited herein.
The switch trolley synchronous detection method provided by the embodiment of the application comprises the steps of firstly obtaining pulse signals respectively output by two encoders, wherein the two encoders are respectively positioned on two switch trolleys, then obtaining mechanical error ranges respectively corresponding to the two switch trolleys, then respectively determining the movement speed and/or displacement of the two switch trolleys according to the pulse signals respectively output by the two encoders, and finally determining whether the two switch trolleys are synchronous according to the movement speed and/or displacement of the two switch trolleys and the mechanical error ranges respectively corresponding to the two switch trolleys. From this, realized carrying out real-time detection to the synchronism when two switch platform trucks move, avoided two roof beam body off tracking and the mechanical damage that cause when the platform trucks move asynchronous, improved the security.
Through the analysis, the encoders can be installed on the two turnout trolleys, so that the synchronism of the two turnout trolleys during movement can be detected in real time according to the pulse signals respectively output by the two encoders. In a possible implementation form, the motion of the two turnout trolleys can be controlled according to the detection result of the synchronism of the two turnout trolleys in the motion process. The above-described case will be specifically described with reference to fig. 3.
Fig. 3 is a schematic flow chart of a switch trolley synchronous detection method according to another embodiment of the present application.
As shown in fig. 3, the switch trolley synchronous detection method includes:
The detailed implementation process and principle of steps 301 to 302 may refer to the detailed description in the above embodiments, and are not described herein again.
And step 304, adjusting the driving signals respectively corresponding to the two turnout trolleys according to the pulse signals respectively output by the two encoders.
And 305, driving the two turnout trolleys to move respectively by using the driving signals respectively corresponding to the two turnout trolleys.
Specifically, two turnout trolleys can be driven to move respectively through two driving motors, and the sizes of driving signals respectively corresponding to the two turnout trolleys are controlled through the rotating speeds respectively controlling the two driving motors, so that the moving speeds and the displacements of the two turnout trolleys are controlled.
During concrete implementation, the pulse quantity that two encoders output respectively can be set up in advance, with the corresponding relation of driving motor's rotational speed to when the pulse signal that two encoders output respectively is acquireed, if according to the pulse signal that two encoders output respectively, confirm that two switch platform trucks are synchronous, then can keep two switch platform trucks corresponding driving motor's rotational speed unchangeable, and then keep the drive signal of two switch platform trucks unchangeable, with control two switch platform trucks continuation synchronous motion.
If the two turnout trolleys are determined to be asynchronous according to the pulse signals respectively output by the two encoders, the rotating speed of the driving motor corresponding to at least one turnout trolley can be adjusted according to the relation between the preset pulse quantity and the rotating speed, and then the driving signal corresponding to at least one turnout trolley is adjusted, so that the two turnout trolleys move synchronously.
In a specific implementation, if the performance parameters of the two encoders are the same, step 304 can be implemented in the following manner.
And step 304a, determining the adjusting rotating speed of the driving motor corresponding to the difference value of the pulse number according to the preset relationship between the pulse number and the rotating speed.
And 304b, adjusting the rotating speed of the driving motor corresponding to the at least one turnout trolley according to the adjusted rotating speed value.
During concrete implementation, the corresponding relation between the pulse quantity output by the encoder installed on the turnout trolley and the rotating speed of the driving motor corresponding to the turnout trolley can be preset, so that the adjusting rotating speed of the driving motor corresponding to the difference value of the pulse quantity can be determined according to the relation between the preset pulse quantity and the rotating speed when two turnout trolleys are asynchronous, namely the pulse quantities output by the two encoders are different. And adjusting the rotating speed of the driving motor of at least one turnout trolley according to the adjusted rotating speed.
For example, if the number m of pulses output by the encoder per second is 3600, the corresponding rotation speed of the motor is n — m × 60/360 rpm (r/min). If the number of pulses output by the encoder 1 corresponding to the turnout trolley 1 per second is 3600, and the number of pulses output by the encoder 2 corresponding to the turnout trolley 2 per second is 3000, the rotating speed of the driving motor 1 corresponding to the turnout trolley 1 can be determined to be 600r/min and the rotating speed of the driving motor 2 corresponding to the turnout trolley 2 to be 500r/min according to the preset relationship between the number of pulses and the rotating speed.
According to the preset relationship between the pulse number and the rotating speed, the adjusting rotating speed of the driving motor corresponding to the difference 600 of the pulse number can be determined to be 100 r/min. The rotating speed of the driving motor 1 can be reduced to 500 r/min; or increasing the rotating speed of the driving motor 2 to 600 r/min; or adjusting the driving motor 1 and the driving motor 2 to equal rotating speeds at the same time, for example, adjusting the rotating speeds of the driving motor 1 and the driving motor 2 to 550r/min to increase the adjusting speed.
It should be noted that, in the embodiment of the present application, the power supply frequency of the motor may be adjusted by the frequency converter, so as to adjust the rotation speed of the motor. The frequency converter can be composed of a rectifying unit (alternating current to direct current), a filtering unit, an inverting unit (direct current to alternating current), a braking unit, a driving unit, a detection unit and a microprocessing unit, and controls the power control equipment of the motor by changing the frequency mode of the working power supply of the motor, so that the rotating speed of the motor is adjusted.
The switch trolley synchronous detection method comprises the steps of firstly obtaining pulse signals output by two encoders respectively, then determining whether the two switch trolleys are synchronous according to the pulse signals output by the two encoders respectively, if so, determining that driving signals of the two switch trolleys are unchanged, if not, adjusting the driving signals corresponding to the two switch trolleys respectively according to the pulse signals output by the two encoders respectively, and finally, driving the two switch trolleys to move respectively by utilizing the driving signals corresponding to the two switch trolleys respectively. From this, realized carrying out real-time detection to the synchronism when two switch platform trucks move, and according to the testing result, control the motion of two switch platform trucks, avoided two platform trucks to move roof beam body off tracking and the mechanical damage that causes when asynchronous, improved the security.
