Technical Field

The invention relates to the technical field of mechanical rotary lubrication, in particular to an intelligent data transmission system of a centralized lubrication pump.

Background

With the rapid development of modern development towards high efficiency, high speed, data management, heavy load, energy conservation and reliability, the condition of a friction part in the machine is more severe as a result, and the state of each piece of equipment is extremely required to be effectively monitored, so that the work of well lubricating the engineering machine under the background of big data is an important ring in the work of designing, manufacturing, using, maintaining and managing the engineering machine.

The traditional lubrication maintenance methods comprise a smearing lubrication method, a grease gun grease injection method, a lift car lubrication method and a centralized lubrication method, and specifically comprise the following steps:

1. coating and lubricating method: after the equipment is shut down, the bearing cover is manually disassembled, and the old grease is dug out and coated with new grease. The method is simple but can not completely remove the dirty grease which contains a large amount of metal abrasive dust and is aged and deteriorated and remains among the bearing roller, the roller path and the grid frame. The bearing cannot be taken down for cleaning due to structural limitation, so that the long-term residual dirty grease can accelerate the abrasion and even damage of the bearing.

2. A butter machine filling method: after the equipment is stopped, grease is filled into each bearing by using a grease gun until the dirty grease at the shaft seal is blown out. The method can thoroughly remove the dirty grease at partial rollers, raceways and grids. The grease machine has the disadvantages that under the pressure of the grease machine, grease under pressure only takes a path with the minimum resistance, and dirty grease in the path can move forwards under the pushing of the pressure until the dirty grease overflows; but the dirty fat in the rest of the way will remain in place and cannot be replaced.

3. A lift car lubrication method: the lift truck is used for conveying workers to a high-altitude lubricating point, the workers are filled through a grease filling gun, a grease filling pump and an alignment grease filling port, and when grease overflows from the grease filling port, the operation is finished. The method has the advantages of large investment, potential safety hazard in high-altitude operation of workers and long maintenance operation time.

4. A centralized lubrication method: although centralized lubrication can be achieved without stopping the machine, the potential safety hazard of workers in high-altitude operation is avoided, the electric lubricating pump needs to be installed at the position of the mechanical bearing equipment needing to be lubricated, firstly, the input cost is high, secondly, the electric lubricating pump is installed in the open air, the service life is short under the influence of long-term environmental erosion, the grease is difficult to convey due to the fact that the grease is solidified when the temperature is too low, and dust and sand wind enter the grease which is always stored in the lubricating pump.

In addition, the lubrication cannot be managed in a data mode at present, the condition of lubricating grease consumption cannot be calculated according to the working hours of each device through system data analysis, and therefore the lubrication maintenance work cannot be prompted by a system.

An effective solution to the problems in the related art has not been proposed yet.

Specifically, a cluster system environment is used as an execution environment, when a new data file is generated in an original data directory, a monitoring mechanism of file system change is started, file monitoring and data processing are carried out, and a log is recorded; executing and monitoring a data processing flow, and representing all tasks in one data processing flow by adopting a DAG (direct current) diagram, wherein a vertex represents one task, and a pointing mode among the vertexes represents a dependency relationship among the tasks; when the flow is executed, all tasks are executed in a manner similar to topological sorting; selecting a task with Ready state from the task queue each time, and after the task is executed correctly, reducing the in-degree of the subsequent task depending on the task by one; recording PID information of the task when the task is executed, periodically checking the running state of the task after the task is executed, and adopting the following feedback mechanism aiming at different running states: restarting a task once a problem occurs to the task; when the failure times of the task exceed a certain threshold value, discarding the task and recording a log; if the execution time of a certain task exceeds the tolerance limit of the system, the task is considered to have an unknown error, the task is forced to be ended, and the task is tried to be executed again; setting a cross protection process for a process, starting two processes when the cross protection process is started initially, wherein one process is a system daemon process and is used for executing file monitoring and triggering, workflow execution and monitoring, log recording and crash recovery, and the other process is a system protection process and directly calls a system Cront process to carry out system protection; the two processes can carry out periodic handshake communication, and once one party does not feed back response and exceeds a certain number of times of limit, the information sending party considers that the information receiving party is abnormal and needs to finish and restart the information receiving party; meanwhile, the Cront process periodically receives heartbeat information from both the sending information and the receiving information, and if the heartbeat information of any one party is not received, the cross protection process is restarted; carrying out log recording; when the system is recovered from a state, the system firstly checks the breakpoint information of task execution recorded in a crash log, namely the timestamp of the last processed file, and recovers the execution of the task according to the information.

If the FileMonitor file descriptor is set, it indicates that the process finds that there is a new file under the detection directory, and the file is added to the waiting queue. When the number of tasks in the task pool is less than the number of tasks that can be executed simultaneously, the tasks in the queue are added into the task pool, and at this time, the process generates a sub-process through a fork system call to execute the newly added sub-task. The execution of the newly added subtask is logged. After the task is completed, the task is removed from the task pool. There is also a case where no descriptor is set after the time, i.e., a TimeOut, at which time the TimeOut function is called, the various tasks in the run queue are checked, and if the protection process has not responded, an attempt is made to restart the protection process.
