Description
Technical Field
The invention relates to the technical field of rail engineering diagnosis, in particular to a rail diagnosis electrical control method applied to ultrasonic detection of railway steel rails.
Background
With the continuous increase of railway mileage in China, railway transportation speed is continuously accelerated, urban rail transit is developed more and more, and the requirements on engineering machinery and equipment for ensuring the safety of railways and urban rail transit are higher and higher. At present, railway track monitoring equipment taking ultrasonic transmission as a basic principle is widely applied to the fields of railway engineering systems and urban rail transit. The rail monitoring device using ultrasonic transmission as a basic principle needs to use coupling liquid as a medium so that ultrasonic waves can smoothly enter the inside of a rail to realize ultrasonic transmission, and therefore, it is necessary to design an intelligent control method of the coupling liquid.
The flaw detection electric control system usually comprises a plurality of relatively independent subsystems with relatively independent functions, and the relatively independent subsystems are mutually cooperated to provide good monitoring environment and conditions for realizing stable, high-quality and high-efficiency flaw detection work of the steel rail by ultrasonic flaw detection monitoring of the steel rail. However, when the existing rail flaw detection vehicle works, a plurality of electrical subsystems need to be controlled and adjusted by an operator in real time according to actual working conditions, and meanwhile, the whole electrical system is an open-loop system, lacks of real-time feedback and has no intelligent characteristic. Therefore, the existing steel rail flaw detection electric control system mainly has the following technical defects:
1) in the steel rail flaw detection operation process, because the liquid in the liquid box has fine impurities and the liquid in the pipeline is stored for too long, and other factors, the phenomenon that the spraying device is blocked by some fine impurities can be caused although the liquid is filtered by the filter. The operator can find the blockage state of the spraying device by observing the picture of the monitoring camera only by seeing the long-distance lost bottom wave on a B-type graph (a display mode of an ultrasonic flaw detection sectional graph, which can display a longitudinal sectional image of a detected steel rail and indicate the approximate size and the relative position of an ultrasonic reflector in the steel rail, wherein the abscissa represents the position of a damage mileage and the ordinate represents the depth of a damage below the rail surface). Therefore, the blockage phenomenon of the spraying device cannot be found in time, and the condition that the monitoring data is invalid in a quite long distance exists.
2) In the process of rail flaw detection operation, the actions of the ultrasonic operation device are controlled in an open loop mode, whether the ultrasonic operation device acts or not needs to be observed through a monitor display or a get-off car, and whether the ultrasonic operation device acts or not needs to be observed and confirmed through naked eyes of people.
3) In the process of steel rail flaw detection operation, ice slag or mud blocks exist in the ultrasonic operation mechanism in rainy and snowy days and in a humid environment for long-term operation, so that the pressing action of the ultrasonic operation device is not influenced, and once the phenomenon occurs, the condition that monitoring data in a long distance is invalid can be caused.
Disclosure of Invention
In view of the above, the present invention provides an electrical control method for rail diagnosis, so as to solve the technical problems that in the existing electrical control method for rail diagnosis, a plurality of subsystems need to be controlled and adjusted in real time by an operator according to actual operation conditions, and the whole electrical system is open-loop, lacks real-time feedback, and does not have the characteristic of intelligence.

Further, after the track diagnosis electrical control system is powered on, the main controller firstly judges whether the power source is started or not, and if the power source is not started, the starting condition of the power source is repeatedly monitored. And if the power source is started, the flow monitoring unit acquires the flow information of the liquid and then feeds the flow information back to the main controller. And the main controller compares the flow information feedback value with an initial set value after receiving the flow information feedback value, and clears the sound-light alarm and prompt information of the alarm device if the flow information feedback value is consistent with the initial set value. If the flow information feedback value is inconsistent with the initial set value, the main controller sends alarm information to the alarm device, and the alarm device immediately sends out audible and visual alarm and prompt information after receiving the alarm information to remind an operator to process, restore the spraying unit to a normal spraying state and check whether the power source is started.

And if the gas source is started, the pressure monitoring unit acquires gas pressure information and then feeds the pressure information back to the main controller. And the main controller compares the pressure information feedback value with an initial set value after receiving the pressure information feedback value, if the pressure information feedback value is consistent with the initial set value, the action of the ultrasonic operation device is normal, and the main controller clears the alarm information and returns to inquire whether the air source is opened or not. If the pressure information feedback value is inconsistent with the initial set value, the action of the ultrasonic operation device is abnormal, the main controller sends audible and visual alarm and prompt information to the alarm device to remind an operator to process, the ultrasonic operation device is restored to a normal action state, and then whether the air source is started or not is checked. And the actions are repeatedly executed until the track diagnosis electrical control system is powered down.
