Detailed Description
The core of the invention is to provide a monitoring method of a rail train brake control system, which can improve the reliability of the brake control system and the availability of a train.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a flow chart of a monitoring method of a rail train brake control system according to an embodiment of the present invention.
the detection method provided by the specific embodiment of the invention comprises the following steps:
and acquiring and recording the action times of the valve components of all modules in the brake control system. Because each module comprises components such as a mechanical valve, an electromagnetic valve and the like, the action times of the valve component directly relate to the service life of the valve component, and when the valve component acts once, and the intelligent module detects that the valve component acts once, the action times are recorded in an accumulation mode by adding one to the recorded integral action times, and when the action times need to be obtained, the addition result is provided.
and after the addition result is obtained, comparing the addition result in real time, namely judging whether the action times reach the preset times. The preset times are obtained according to the safe use times of the valve component, and if the preset times are reached, the potential safety hazard of the valve component possibly exists, and the valve component needs to be overhauled.
If the judgment result is yes, the maintenance prompting information is sent out.
and if the judgment result is negative, detecting the next index. And acquiring and recording the running kilometers of the rail train, and acquiring the running kilometers through an MVB network.
and judging whether the running kilometers reach the preset kilometers. After the train runs for a certain number of kilometers, even if the number of times of action of the valve component is not large, potential safety hazards can exist, and therefore the number of kilometers which are possibly problematic is set as a preset number of kilometers according to experience, and the overhaul standard is reached.
if the judgment result is yes, the maintenance prompting information is sent out.
and if the judgment result is negative, detecting the next index. And acquiring the service time of each module in the brake control system after leaving the factory. Specifically, the electronic tag of each module records the date of leaving factory, the date of leaving factory can be detected through the RFID radio frequency technology, the current date is obtained at the same time, and the date of leaving factory and the current date are subtracted to obtain the service time.
And judging whether the service time reaches the preset time. The preset time is equivalent to the quality guarantee period of the module, and potential safety hazards can exist when the preset time exceeds the quality guarantee period, so that the module needs to be overhauled.
If the judgment result is yes, the maintenance prompting information is sent out.
If the judgment result is negative, the operation times are obtained and recorded again and judged, namely the steps are carried out circularly.
The method comprises the steps of collecting and recording parameters such as the action times of valve components of each module in the system, the train running kilometers, the module service time and the like, if the parameters reach preset values, indicating that the parameters reach maintenance standards, sending out maintenance prompting information to prompt workers to maintain, early warning, avoiding maintenance after each module breaks down, improving the reliability of a brake control system and the availability of a train, and realizing the intelligent maintenance of the whole service life of the system.
in the detection method provided by the specific embodiment of the invention, sending out the maintenance prompting information comprises obtaining the fault type according to the judgment result; converting the fault type into a corresponding fault code; and displaying the fault code through the display screen. The system sends the information of the fault code to the display screen through the CAN network to prompt the position and the fault type of the specific working part of the worker, so that the worker CAN conveniently overhaul.
Meanwhile, whether the maintenance is finished or not can be judged after the maintenance prompting information is sent;
if the maintenance is not carried out, continuing to prompt; if the maintenance is finished and the judgment result is yes, resetting the action times, the number of kilometers of operation and the date of leaving factory, then obtaining and recording the action times again and judging, and circularly performing the steps to ensure the safety and the stability of the train in real time.
The monitoring method of the rail train brake control system provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
