Description

Technical Field

[0001] The invention provides a method for data collection and processing of fully mechanized mining working face equipment, belonging to the technical field of data collection and processing. Background Art

[0002] Equipment data collection of comprehensive mining working faces is the basis of comprehensive mining intelligence. Without data, intelligence cannot be achieved. At present, the level of informatization of coal mine working faces has a certain foundation. However, due to various network or equipment reasons, some production process data with incomplete data quality have been formed. When using the data for analysis, reasonable results cannot be obtained. Therefore, when collecting data, it is a more reasonable way to manage the data collection and exception handling logic, and improve the data quality through the process of collecting data.

[0003] In the intelligent operation of comprehensive mining, correct and timely judgment of the communication and data of each equipment is the basis for data monitoring, automatic control, and automatic and manual collaboration. Proper handling of data processing during collection communication, equipment abnormalities, and communication abnormalities is the basis for subsequent data display, intelligent decision-making, and intelligent analysis.

[0004] At present, due to the harsh on-site environment, there are interferences to communication data caused by frequency conversion, magnetic attraction, current, vibration, etc. in the intelligent comprehensive mining. There are also unstable equipment programs that require intelligent manufacturers to discover abnormalities and automatically reconnect. As a result, abnormalities often occur during data collection, and the validity and integrity of the data are low, which cannot provide accurate and effective data for subsequent analysis. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a method for data collection and processing of comprehensive mining working face equipment, which generates offline data when the program is started to ensure data integrity. The process design is compatible with interface multiplexing, connection judgment, etc. When the equipment data is interrupted, restarted, or shut down, the valid data judgment and valid data interruption time judgment of each process are used to perform device interface reconnection and clearing functions, thereby reducing data anomalies caused by false connections between equipment and servers and invalid data congestion, ensuring the validity and integrity of equipment data, and better serving intelligent services.

[0006] The technical solution adopted by the present invention is: a method for data collection and processing of fully mechanized mining working face equipment, comprising the following steps: S1, when the data collection program is started, the equipment offline data is generated, marking the start of equipment data collection from this time; the equipment is the equipment used to perform coal mining tasks on the fully mechanized mining working face; S2, establish communication according to the configured device interface information; S3, after communication is established, collect and read device data at the set frequency, send request data information as needed, and receive data information fed back by the device; then verify and parse the received device data to analyze whether the content complies with the protocol information and whether it is the required valid data. If the data is valid, execute S5; if the data is invalid, execute S4; S4, when it is found that the data returned by the communication interface is not valid data, it is necessary to judge the continuous time of the invalid data. When the continuous time does not exceed the set time, the judgment ends and waits for the next judgment; when the continuous time exceeds the set value, it returns to execute S2; S5, storing the valid data in the database according to the format, completing the data marking, and completing the storage of the valid data; S6, establish a task, determine whether the continuous interruption time of storing valid data exceeds the set value. When the interruption time of valid data exceeds the set value, it is considered that the device is offline. At this time, an offline data packet of the device is generated and stored in the database. Otherwise, continue to determine; S7, when the data acquisition program is closed, first determine whether the device currently has valid data, and then close the interface communication between the program and the device.

[0007] The establishment of communication according to the configured interface information in step S2 includes the following two situations: S21, when the device shares an interface with another device, mark the interface type and reuse it directly. After the communication connection is completed, execute S3. When the communication connection fails, return to execute S2 at a fixed time. S22, when the device uses the interface alone, connect the interface and establish communication. If the communication connection is successful, execute S3. If the communication connection fails, return to execute S2 at a fixed time.

[0008] When the direct multiplexing communication connection of the shared interface fails in step S1, the device is reconnected after clearing the data of the interface.

[0009] When executing device reconnection, all devices connected to the interface need to execute the reconnection command.

[0010] In step S7, if there is valid data, the device offline data is generated and stored in the database, and the program is closed. If there is no valid data, the program is closed directly.

[0011] In step S1, when the data acquisition program is started, the devices that are not detected are uniformly identified as offline devices, and device offline data is generated. The device offline data records the status data of each device when the data acquisition program is started.

[0012] The data acquisition program is deployed on the data acquisition server of the mine chute centralized control system.

[0013] The beneficial effects of the present invention compared to the prior art are as follows: the present invention makes the entire equipment data monitoring process more complete by adding offline data at the beginning of the equipment, adding offline data when the valid data continuous time is determined, and adding offline data at the end. If only valid data is recorded, it is impossible to determine whether the intelligent monitoring is not running or the equipment has no feedback data. The integrity of the offline data clarifies the entire monitoring time period and fully feeds back the overall equipment status during the operation of the intelligent system, making data display, analysis, and decision-making more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the accompanying drawings: Figure 1 Flow chart of the method of the present invention. DETAILED DESCRIPTION

[0015] like Figure 1 As shown, the present invention provides a method for data collection and processing of equipment in a comprehensive mining working face, which mainly includes data collection and processing during equipment startup, normal operation of the equipment, and shutdown of the equipment. At startup, add offline data to the equipment, and then collect equipment data to complete the process of creating equipment data from scratch. During the data collection process, determine whether the collected data is valid data. In the case of valid data, the generated equipment data is stored normally. In the case of invalid data, another set of waiting or reconnection interfaces is used. For valid data, it is determined in real time whether the data is interrupted. When the program is closed, check the data, close the interface, and perform the final data processing.

[0016] Specifically, the software program involved in the method of the present invention is deployed in the data acquisition server of the chute centralized control system. The data acquisition server is responsible for the functions of interface judgment connection, data analysis, data judgment, timeliness judgment, interface reconnection, offline data generation, etc., and stores all data that need to be stored in the database.

[0017] The implementation steps of the method of the present invention are as follows: S1, when the data collection program is started, the device offline data is generated (all undetectable devices are judged as offline devices, thereby generating device offline data), and it is marked that the device data collection starts from this time, completing the initial data collection record.

[0018] S2, according to the configured device interface information, after checking and analyzing the interface, determine whether the interface is shared. If the data acquisition program interface is shared with other device interfaces, execute S21, otherwise execute S22.

[0019] S21, when the data acquisition program interface shares an interface with other devices, mark the interface type, reuse it directly, and then establish communication. If the communication connection is successful, execute S3. If the communication connection fails, return to execute S2 at a fixed time. After the communication connection fails here, first determine whether the communication of other devices is valid by whether there is valid data (within 3 seconds). If the communication of other devices is valid, the device cannot perform the operation of clearing the interface data and closing the communication interface. If the communication of other devices is abnormal, the program executes the operation of clearing the interface data and closing the communication interface, and then reopens the communication interface to establish communication and read data. Finally, send a notification to enable the device with the shared interface to re-establish communication and read data (the interface will no longer be opened before the other devices establish communication).

[0020] S22, the device uses the interface alone, connects the interface, establishes communication, and executes S3 if the communication connection is successful. If the communication connection fails, it returns to execute S2 at a fixed time.

[0021] S3, after communication is established, collect and read device data at the set frequency, send request data information as needed, and receive device feedback data information. Then verify and analyze the received device data to see if the content complies with the protocol information and whether it is the required valid data. If the data is valid, execute S5, otherwise execute S4.

[0022] S4, when it is found that the data returned by the communication interface is not valid data, it is necessary to judge the continuous time of the invalid data. When the continuous time does not exceed the set time, the judgment ends and waits for the next judgment; when the continuous time exceeds the set value, it returns to execute S2.

[0023] S5, stores the valid data in the database according to the format, completes the data marking, and completes the storage of the valid data.

[0024] S6, establish a task, determine the continuous interruption time (10 seconds) for storing valid data, if the interruption time exceeds the set value (10 seconds), execute S61, if it does not exceed the set value (10 seconds), continue to determine.

[0025] S61: When the effective data interruption time exceeds the set value (10 seconds), the device is considered to be offline. At this time, an offline data packet of the device is generated and stored in the database.

[0026] S7, when the program is closed, first determine whether the device currently has valid data, then close the interface communication between the data acquisition program and the device. If there is valid data, generate device offline data and store it in the database to complete the program closing. If there is no valid data, directly complete the program closing.

[0027] Through the above method, continuous and high-quality equipment operation data from the beginning to the end of the collection process is obtained.

[0028] The present invention forms an automated management process for effective connection of device data based on the determination of effective data, continuous time of effective data, and interface multiplexing, and is a process for automatically completing disconnection and reconnection of device acquisition communication without relying on device restart or human judgment.

[0029] The method of the present invention is applicable to data processing in data collected by all electronic control equipment such as coal mining machines, hydraulic supports, scraper conveyors, frequency converters, water pumps, fans, etc. on the fully mechanized mining working face.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
