Detailed Description
The core of the invention is to provide a protection method of the air compressor, which is beneficial to timely finding out the condition that the continuous work of the air compressor is overtime, thereby effectively reducing the occurrence probability of the condition that the air compressor frequently works.
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. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for protecting an air compressor according to the present invention, the method including the following steps:
step S101: the continuous working time of the air compressor is obtained by monitoring the air compressor.
In the scheme of this application, because the duration of the continuous operation duration that needs acquire the air compressor machine, consequently need continuously monitor the air compressor machine usually, can be real-time supervision, also can be according to the continuous monitoring of monitoring cycle. When the air compressor is monitored, whether the air compressor is operated at the moment can be determined through related signals, for example, the determination of the operating state of the air compressor is performed through the air compressor operation signal M111 and the air compressor cut-off signal M181, when the M111 signal is at a high level and the M181 signal is at a low level, it indicates that the air compressor is operating, and when the M111 signal is at a low level or the M181 signal is at a high level, it can be determined that the air compressor is not operating. Of course, in other embodiments, the operating state of the air compressor may be determined by other types of signals, which does not affect the implementation of the present invention.
It is convenient to understand that the step S101 is described in detail in the embodiment of continuous monitoring according to the monitoring period, and in a specific embodiment of the present invention, the step S101 may specifically include the following three steps:
the method comprises the following steps: continuously monitoring the working state of the air compressor according to a preset monitoring period;
step two: when the air compressor is monitored to be in a working state, increasing the numerical value of the first counter by a monitoring period, and when the air compressor is monitored to be in a non-working state, setting the numerical value of the first counter to zero;
step three: and acquiring the value of the first counter as the acquired continuous working time of the air compressor.
The preset monitoring period can be set and adjusted according to actual conditions, for example, the monitoring period is adjusted according to factors such as the normal continuous working time of the air compressor in actual application, the switching frequency of the working state and the like. In one embodiment, the monitoring period may be set to be shorter, for example, 1 second, so as to avoid the situation that the switching of the operating state of the air compressor is missed when the monitoring period is too long.
In this embodiment, the duration of the operation of the air compressor is determined by using the first counter, that is, when it is monitored that the air compressor is in the operating state, the value of the first counter is incremented by the monitoring period, and when it is monitored that the air compressor is in the non-operating state, the value of the first counter is set to zero. Referring to fig. 2, a logic timing diagram illustrating the duration of the operation of the air compressor according to an embodiment is shown. In the embodiment of fig. 2, all the M181 signals are at a low level, that is, the M181 signal is always equal to 0. When M111 is equal to 1, it may be determined that the air compressor is in the operating state, and the value of the first counter is incremented, where each incremented value is equal to the monitoring period. Accordingly, when M111 is equal to 0, it may be determined that the air compressor is in the operating state, and the value of the first counter is immediately set to zero. For example, in the embodiment of fig. 2, the first counter is set to zero at 2498 th second, 4600 th second, and 6600 th second. The value of the first counter is continuously increased from 1000 th to 2498 th seconds, from 3000 th to 4600 th seconds, from 5000 th to 6600 th seconds, and the value of the first counter is also continuously increased.
Step S102: and outputting first fault prompt information when the continuous working time of the air compressor is judged to be greater than or equal to the preset continuous time threshold.
The predicted duration threshold may also be set according to practical circumstances, for example, 25 minutes, i.e., 1500 seconds in the embodiment of fig. 2. If the air compressor is in the working state from the 3000 th to the 4600 th seconds, the 4500 th seconds are started until the 4600 th seconds, and first fault prompt information is output. The first fault prompt information can be output through the train network control system, and the first fault prompt information can carry information such as the position of the air compressor, the current continuous working time of the air compressor and the like. In addition, in order to bring attention to workers, the first fault prompting information can be output in combination with sound and light.
The protection method for the air compressor provided by the embodiment of the invention comprises the following steps: the method comprises the steps of obtaining the continuous working time of the air compressor by monitoring the air compressor, and outputting first fault prompt information when the continuous working time of the air compressor is judged to be greater than or equal to a preset continuous time threshold.
In the scheme of this application, monitor the air compressor machine to obtain the duration of operation of air compressor machine, owing to obtained the duration of operation of air compressor machine, alright in order when this duration of operation is more than or equal to predetermined duration threshold value, output first trouble prompt message. Because the first fault prompt information is output, the situation that the air compressor continuously works overtime can be found by the staff in time, the staff can be favorably used for closing the air compressor in time, and therefore the occurrence probability of the situation that the air compressor frequently works can be reduced. Therefore, the scheme of this application can protect the air compressor machine, has reduced the emergence probability of the condition of air compressor machine frequent work effectively.
In a specific embodiment of the present invention, after step S102, the method further includes:
and receiving a first cutting instruction, and turning off the air compressor after receiving the first cutting instruction.
In the foregoing embodiment, when it is determined that the duration of the air compressor is greater than or equal to the preset duration threshold, only the first fault notification message is output, and the air compressor is not directly turned off, because it is considered that the air compressor still needs to operate in some occasions. For example, in a specific situation, a driver determines that a related pipeline leaks air, but does not directly turn off an air compressor to ensure the driving safety of the train in order to maintain partial braking force of the train. In this embodiment, the air compressor may be turned off after receiving the first cut-off command, which is usually sent by the driver, that is, after the driver confirms that the air compressor can be turned off after receiving the first failure notification message, the first cut-off command is sent to turn off the air compressor. The air compressor is protected in the occasion that the air compressor is allowed to be closed, and damage to the air compressor due to overlong continuous working time is avoided.
In an embodiment of the present invention, the method may further include the following two steps:
the first step is as follows: acquiring the total working time of the air compressor within a first time before the current moment;
the second step is that: and outputting second fault prompt information when the total working time is judged to be greater than or equal to the preset total time threshold.
In addition to continuous operation, if the air compressor is turned off only briefly, damage to the air compressor may still occur. Therefore, in this manner, the total operating time of the air compressor within the first time period before the current time is obtained. The frequency of acquiring the total operating time length may also be set according to actual conditions, for example, set to 1 second, that is, the total operating time length is acquired every 1 second. When the total working time is judged to be greater than or equal to the preset total time threshold, the fact that the total working time of the air compressor is too long in the previous first time is explained, and then second fault prompt information can be output. The second fault prompt message can carry information such as position information of the air compressor and total working duration of the air compressor, so that a driver can make a decision.
The first time length and the total time length threshold can be set and adjusted according to actual conditions, for example, in the example of fig. 3, the first time length is set to 1 hour, i.e., 3600 seconds, and the total time length threshold is set to 2160 seconds. In the embodiment of fig. 3, the M181 signal and the M111 signal are also used to determine the operating state of the air compressor. That is, when M111 is equal to 1 and M181 is equal to 0, it is determined that the air compressor is in the operating state, and when M111 is equal to 0 or M181 is equal to 1, it is determined that the air compressor is in the non-operating state.
In this embodiment, when M181 is detected to be 1, the value in the relevant counter is directly cleared, that is, the total operating time is counted at a time after the air compressor is cut off, and the operating time of the air compressor before the air compressor is cut off is not counted. Of course, in practical applications, whether the total operating time of the air compressor determined in the first step needs to be considered as the operating time before the air compressor is cut off or not may be set according to actual needs.
In a specific implementation, after the second step, the method may further include:
and receiving a second cutting instruction, and turning off the air compressor after receiving the second cutting instruction. The second cutting instruction and the first cutting instruction are used for turning off the air compressor, so the cutting instructions can be instructions in the same form, the cutting instructions are distinguished into the first cutting instruction and the second cutting instruction in the application, and the difference of the generation reasons of the two instructions is emphasized. Of course, the instructions can be in different forms, and the air compressor can be turned off without affecting the implementation of the invention. After the air compressor is turned off, the worker usually needs to perform relevant fault handling measures, such as repairing a wind leakage part, checking the exhaust state of the safety valve, and the like.
