Description

Technical Field

[0001] The invention relates to a method, a device and a storage medium for processing open-pit mine production monitoring, and belongs to the technical field of coal mining management. Background Art

[0002] With the rapid development of open-pit coal mining technology, new coal mines are designed and constructed in accordance with intelligent standards in principle. The open-pit coal mine system intelligently monitors the loading quantity of the excavator and the output of the transport vehicle's transportation trips, realizing the intelligentization of coal mine output.

[0003] The existing technology uses Bluetooth or RFID to identify that when the transport truck approaches the excavator, it cannot accurately identify the loading distance between the excavator and the transport truck. The loading relationship between the excavator and the transport truck is realized through Bluetooth pairing, which requires manual intervention. RFID scanning and identification, when the excavator scans and identifies the transport truck, it is easy to trigger a false scan, and it is impossible to accurately determine when the transport truck starts transporting. It can only be determined by the time interval of the subsequent RFID scanning, which is easy to cause false scans and lead to low accuracy. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a method, device and storage medium for processing open-pit mine production monitoring, so as to facilitate monitoring the daily workload of excavator drivers and transport vehicle drivers and facilitate subsequent planning of mining stations.

[0005] To achieve the above object, the present invention is implemented by adopting the following technical solutions:

[0006] In a first aspect, the present invention provides a method for processing open-pit mine production monitoring, comprising:

[0007] Obtain the UWB tag scanning results obtained by scanning the UWB tag on the transport vehicle through the UWB host on the excavator in the preset production area;

[0008] According to the scanning results of the UWB tag, it is determined whether to start loading or end receiving, and the corresponding loading records and transportation records are generated and stored;

[0009] Use the stored loading and transport records to monitor the daily workload of excavator and transport truck drivers.

[0010] Furthermore, judging whether to start loading or end receiving a vehicle based on the scanning result of the UWB tag, generating and storing corresponding loading records and transportation records, includes:

[0011] Obtain the UWB tag scanning results, including the loading start and end marks, and store them in the UWB host scanning and identification record table;

[0012] When the UWB tag scanning result is identified as the loading start sign, it is regarded as the loading start, and the loading start time is recorded in the UWB host scanning and identification record table;

[0013] When the UWB tag scanning result is identified as the end mark, the loading is judged to be completed and the loading end time is recorded in the UWB host scanning and identification record table;

[0014] Take out the loading start time and loading end time recorded in the UWB host scanning and identification record table, store it in the database, and form a loading record;

[0015] After it is determined that loading is completed, the transport vehicle starts transporting, records the start time of transport, and stores it in the database to form a transport record.

[0016] Furthermore, the method further comprises:

[0017] When the UWB tag scanning result is identified as the loading start mark, query whether the latest record in the UWB host scanning and identification record table has an end mark;

[0018] If there is an end mark, the loading start time identified by the current scan is stored in the database table, and a new loading start mark is set without an end mark;

[0019] If there is no end mark, compare the loading start time of the current scan identification with the loading start time of the last record. If the loading start time of the current scan identification is less than the loading start time of the last record, use the loading start time of the current scan identification to update the loading start time of the last record.

[0020] Furthermore, the method further comprises:

[0021] When the UWB tag scanning result is identified as an end mark, query whether the latest record in the UWB host scanning identification record table has an end mark;

[0022] If there is no end mark, determine whether the time difference between the loading end time identified this time and the loading start time recorded last time is greater than the set threshold. If so, update the most recent loading end time and set the end mark.

[0023] Furthermore, if it is determined that the time difference between the loading end time identified this time and the loading start time recorded last time is less than the set threshold, continue to wait for the next UWB tag scanning result that is identified as the end mark and the time difference is greater than the set threshold.

[0024] Furthermore, the method for dividing the production area includes: dynamically adjusting the loading range distance, the waiting loading distance and the loading distance according to the real-time position and working status of the excavator.

[0025] Furthermore, the method also includes: displaying the daily workload, loading records and transportation records of the excavator driver and the transport vehicle driver, and calculating and displaying the driver's salary based on the loading records and transportation records.

[0026] In a second aspect, the present invention provides a device for processing open-pit mine production monitoring, comprising:

[0027] An acquisition module is used to obtain a UWB tag scanning result obtained by scanning a UWB tag on a transport vehicle through a UWB host on an excavator in a preset production area;

[0028] The record generation module is used to determine whether to start loading or end receiving according to the UWB tag scanning results, generate corresponding loading records and transportation records and store them;

[0029] The monitoring module is used to monitor the daily workload of the excavator driver and the transport vehicle driver by utilizing the stored loading records and transportation records.

[0030] In a third aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the aforementioned methods.

[0031] In a fourth aspect, the present invention provides a computer device, comprising:

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The present invention provides a method, device and storage medium for processing open-pit mine production monitoring. The UWB host on the excavator scans the UWB tag on the transport vehicle, which can accurately identify the straight-line distance between the excavator and the transport vehicle. The corresponding loading record and transportation record are generated through the UWB tag scanning result, and the daily workload of the excavator driver and the transport vehicle driver is monitored, which is convenient for the subsequent planning of mining entry;

[0037] 2. The present invention realizes production monitoring and management of excavators and transport vehicles through open-pit mine production monitoring methods, that is, it can monitor the loading status of excavators and transport vehicles in real time, as well as the number of vehicles waiting for loading. The current waiting time for loading can be determined by the number of vehicles waiting for loading. It is convenient for dispatchers to dispatch vehicles, reduce the waiting time and the number of waiting vehicles, and improve production output; UWB recognition has high accuracy, loading is standardized, waiting for loading is limited, and the loading range can be entered quickly and orderly;

[0039] Figure 1 The present invention provides a flowchart of a method for processing open-pit mine production monitoring. DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0041] Embodiment 1: This embodiment introduces a method for processing open-pit mine production monitoring, including:

[0042] Obtain the UWB tag scanning results obtained by scanning the UWB tag on the transport vehicle through the UWB host on the excavator in the preset production area;

[0043] According to the scanning results of the UWB tag, it is determined whether to start loading or end receiving, and the corresponding loading records and transportation records are generated and stored;

[0044] Use the stored loading and transport records to monitor the daily workload of excavator and transport truck drivers.

[0045] like Figure 1 As shown, the method for processing open-pit mine production monitoring provided in this embodiment specifically involves the following steps in its application process:

[0046] 1) Bind the uwb host to the excavator and the uwb tag to the transport vehicle;

[0047] 2) Determine the distance of the excavator loading range and wait for the loading distance. The loading distance dynamically demarcates the production area based on the site conditions and the excavator working range;

[0048] 3) The UWB host on the excavator scans the UWB label of the transport vehicle and uploads the result to the project platform in real time;

[0049] 4) The platform analyzes the UWB host recognition results and generates loading records and transportation records according to the corresponding rules;

[0050] Loading record: the record of the excavator loading the transport vehicle, including the loading start time and loading end time. The loading record information is stored in the pg database;

[0051] Transportation record: the record information of the transportation vehicle starting transportation after the excavator finishes loading the vehicle;

[0052] 5) Store the loading record information and transportation record data in the project's pg database;

[0053] Loading records and transportation records can not only monitor the daily workload of excavator drivers and transport truck drivers on the platform, but also facilitate enterprise management and statistics of loading and transportation records, and settle drivers' wages based on the loading and transportation records of drivers;

[0054] 6) The platform handles the shipping logic;

[0055] The scanned identification tag information of the UWB host is uploaded to the project platform in real time. Determine whether the UWB host identification result is to start loading or end loading;

[0056] Loading starts:

[0057] Parse the identification record of the uwb host, query the UWB host scanning identification record table redis, and determine whether it is the loading start mark. If so, parse the data and store it in the project platform PG database table dbd_load_transport_record to record the start time;

[0058] Check whether the latest loading record in the uwb host scanning and identification record table redis has an end mark. Determine whether there is an end mark. If there is an end mark, store the scanning and identification information data in the platform pg database table dbd_load_transport_record, and set the start loading flag to 1 and no end mark. If there is, proceed to the next judgment.

[0059] There is no end mark. Compare the loading start time recorded last with the loading time in the scanned identification tag information of the UWB host this time. If the loading start time in this identification information is smaller, use this identification information to update the loading start time, longitude and latitude, altitude and other data recorded last time.

[0060] Loading completed:

[0061] Parse the identification record of the UWB host, query the UWB host scan identification record table redis, and parse whether the data is an end mark. If so, query the last identification record information to see if there is an end mark.

[0062] If there is no end mark, determine whether the time difference between this end time and the loading start time of the most recent identification information record is greater than 1 minute. If yes, update the most recent identification record and set the end mark and end time. If less than 1 minute, continue to wait for the next identification record with a loading end mark and a time difference greater than 1 minute.

[0063] Take out the most recent identification record (complete identification record, including start mark and end mark), save the record information of start mark and end mark to the platform PG database dbd_loading table to generate loading record information and display it in the project, save the end mark to the dbd_transport table to generate transportation record information and display it in the project. The excavator has finished loading this time and is waiting for the next loading.

[0067] Project platform PG database table information:

[0068] dbd_load_transport_record: uwb host scan identification record table, identification record table. Since the information scanned by the uwb host is uploaded in real time, it is not a complete scan start and end record (scan tag start-scan tag end a complete scan record), and the complete scan record needs to be stored for subsequent tuning and modification of rule parameters. The data includes but is not limited to: the start mark, end mark, upload start mark time, and upload end mark time uploaded by the uwb host;

[0069] dbd_transport: Transport vehicle transport record table, which records the transport start time and which excavator loaded the vehicle. The data includes: transport time (the time when the uwb scan tag ends) and which excavator loaded the vehicle;

[0070] dbd_loading: excavator loading record table, which transport vehicle the excavator loads and records the start loading time (the time when the uwb scans the tag start mark) and the end loading time (the time when the uwb scans the tag end mark);

[0071] Start mark (loading start status): the distance between the tag scanned by the uwb host and the host is judged;

[0072] The label on the transport vehicle moves from 30m away to within 30m, and uploads mark 1 (the mark for the start of excavator loading).

[0073] Continuous state (continuous loading state): the distance between the tag scanned by the uwb host and the host is judged;

[0074] The label on the transport vehicle moves from 17.5m outside to within 17.5m, and uploads mark 3 (excavator continues loading).

[0075] End mark (loading end status): the distance between the tag scanned by the uwb host and the host is judged;

[0076] The label on the transport vehicle moves from within 17.5m to outside 17.5m, and uploads mark 4 (explanation for excavator loading).

[0077] This embodiment provides a method for processing open-pit mine production monitoring. The UWB host on the excavator scans the UWB tag on the transport vehicle, which can accurately identify the straight-line distance between the excavator and the transport vehicle. The corresponding loading record and transportation record are generated through the UWB tag scanning result, and the daily workload of the excavator driver and the transport vehicle driver is monitored, which is convenient for the subsequent planning of mining and entering the station; this embodiment realizes the production monitoring and management of the excavator and the transport vehicle through the open-pit mine production monitoring method, that is, the loading status of the excavator and the transport vehicle, as well as the number of vehicles waiting for loading on the transport vehicle can be monitored in real time, and the current waiting time for loading can be judged by the number of vehicles waiting for loading. It is convenient for dispatchers to dispatch vehicles, reduce the length of waiting time and the number of waiting vehicles, and improve production output; UWB recognition has high accuracy, loading is standardized, waiting for loading is limited, and the loading range is quickly and orderly entered; this embodiment divides the production area and centrally manages to prevent cross waiting. The production dispatcher judges the waiting time for loading, which is convenient for the mobilization of production vehicles and optimizes production efficiency. The production dispatcher can judge which excavator is busy without going to each excavator.
