[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The full life cycle management system of the belt conveyor roller according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0027] Figure 1 The schematic diagram of the structure of a full life cycle management system for belt conveyor rollers proposed in the embodiment of the utility model is as follows: Figure 1As shown, the system includes: a plurality of Radio Frequency Identification (RFID) signal tags 10 , a signal receiving device 20 and a background management server 30 .

[0028] Among them, multiple radio frequency identification RFID signal tags 10 are respectively installed at each group of rollers along the mining belt conveyor, and the signal tags are set one by one corresponding to the rollers. Each signal tag 10 is configured with the unique ID information of the corresponding roller.

[0029] The signal receiving device 20 is integrated in the inspection device, and the signal receiving device establishes a wireless connection with a plurality of signal tags within a working range to read the ID information stored in the signal tags through near field communication.

[0030] The signal receiving device 20 also establishes a wireless connection with the background management server 30 and sends the ID information to the background management server 30 .

[0031] The background management server 30 is equipped with a roller life cycle management program, queries the management data of the corresponding roller according to the received ID information, detects the operating status of the roller according to the management data, and records the operating data of each group of rollers.

[0032] Specifically, the utility model uses Radio Frequency Identification (RFID) equipment as the main equipment for the whole life cycle management of rollers, and utilizes the high frequency characteristics, low power consumption and high integration of RFID equipment to install signal tags 10 and signal receiving devices 20 on the rollers and inspection equipment respectively, and conducts near-field communication through the integrated RFID equipment to exchange data.

[0033] Among them, an RFID passive signal tag 10 is installed at the corresponding position of each group of rollers along the mining belt conveyor, each group of rollers corresponds to an RFID passive signal tag 10, and the unique identity code (ID) of the roller corresponding to itself is written into each RFID passive electronic tag 10. That is, each group of rollers is programmed with unique identity ID information in the global belt conveyor, and the ID information of each group of rollers is different, so that the unique identity ID can be used to manage the entire life cycle of each roller in the future.

[0034] For example, the full life cycle management includes recording the full life cycle data of each roller, including the status data of each roller at different times and the fault record data of the same location, etc. The full life cycle management also includes abnormal status detection of each roller based on the unique ID information.

[0035] Specifically, when installing RFID signal tags at each set of rollers, as a possible implementation method, according to the actual layout of the belt conveyor support, the positions of each roller are in a straight line in the longitudinal direction, such as Figure 2 As shown, a signal tag is arranged on each group of rollers along the belt conveyor, that is, the signal tag is arranged one by one with the rollers. According to the frame form and roller type adopted by the belt conveyor, the signal tag can be fixedly arranged on the bracket of each group of rollers.

[0036] In actual application, the system is based on the wireless radio frequency communication principle of RFID equipment. When the signal receiving device 20 is within a certain range from the signal tag 10, the signal reception can be completed. During the inspection of the belt conveyor rollers, the signal receiving device 20 performs near field communication with each signal tag in sequence, and the roller currently being inspected is used as the target roller. The signal receiving device exchanges data with the signal tag on the target roller, reads the ID information stored in the target signal tag, and sends the currently read target ID information to the background management server 30 for subsequent life cycle management.

[0037] In one embodiment of the utility model, the signal receiving device 20 can be a card reader or other types of signal receivers, and the signal receiving device 20 is integrated in the inspection equipment, and the inspection equipment includes a mobile terminal of the inspection personnel and an inspection robot. Among them, when the inspection robot is used as the inspection equipment, manpower can be reduced, and the inspection robot performs automated inspection.

[0038] As described above, in order to ensure normal communication between the signal tag 10 and the signal receiving device 20, it is necessary to ensure that the distance between the two is close enough. Therefore, in this embodiment, when the inspection device is the inspection robot, the inspection robot moves step by step in the preset range along the belt conveyor according to the arrangement order of each group of rollers, and the distance between the inspection robot and the belt conveyor is less than the signal transmission distance of the signal receiving device.

[0039] Specifically, at each inspection cycle, the inspection robot is controlled to start from the first group of rollers and run within a preset range along the belt conveyor, and run along the line in sequence according to the arrangement order of each group of rollers. The preset range is determined according to the communication distance between the signal receiving device and the signal tag. The distance between the inspection robot and the belt conveyor is less than the signal transmission distance of the signal receiving device, so as to ensure that the signal receiving device on the inspection robot can read the ID information in the signal tag.

[0040] When the RFID signal tag 10 establishes a wireless connection with the signal receiving device 20 to exchange information, the signal receiving device continuously reads the signal tag at a preset frequency; compares the signal strengths of multiple communication signals interacting with the signal receiving device, takes the signal tag with the largest signal strength as the target signal tag, and receives the target ID information sent by the target signal tag.

[0041] For example, Figure 2 As shown, when the inspection personnel or the inspection robot approaches the roller, so that the signal receiving device 20 is close enough to the roller tag along the line, the signal receiving device can detect multiple signal tags 10 within its working range for communication ( Figure 2 The closer the distance between the signal receiving device 20 and the signal tag 10 is, the stronger the signal strength of the communication between the two is (for example, Figure 2 The signal strength of the second roller in the communication with the receiving device 20 is the strongest). Therefore, the receiving device such as the card reader can be controlled to continuously read the electronic tag at a certain frequency, and compare the signal strengths of each established communication link. The device selects the roller with the strongest signal, that is, the roller closest to the current detection target roller, and uses the label on the roller as the target signal label, and receives the target ID information sent by the target signal label ( Figure 2 The middle one is the signal label corresponding to the second roller).

[0042] It is understandable that the utility model can realize near field communication by using RFID equipment, and installs passive electronic tags near the belt rack, which has the advantages of simple installation and high stability. In addition, the size and dimensions of the RFID card reader are relatively suitable, which is convenient for integration into inspection equipment such as mobile phones and inspection robots, so that it is easy to implement in practical applications.

[0043] Furthermore, the background management server 30 is pre-installed with a full life cycle management program. It queries the management data of the corresponding roller according to the received ID information, and performs life cycle management operations of the roller according to the management data. The operations include detecting the operating status of the roller, recording the operating data of each group of rollers, and recording roller replacement data.

[0044] After the signal receiving device 20 establishes a wireless connection with the background management server 30, a request is sent to the background management server, and the background management server 30 calls the management data of a corresponding group of rollers from the database according to the ID information. The roller management data can be various data related to the operation status detection and service life management of the rollers. For example, the roller management data can include the installation time, manufacturer, theoretical life, rated parameters such as the maximum temperature of the rollers, brand model, generation batch, and historical fault records detected before, etc. of the group of rollers currently detected.

[0045] Furthermore, the background management server 30 analyzes the acquired roller management data and detects the operating status of the target roller, that is, determines whether the target roller is in a normal operating state, whether it has reached its expected service life, etc., so as to achieve the purpose of real-time monitoring of the operating status of the belt and roller.

[0046] As an example, the process of the background management server 30 detecting the operating status of the roller based on the management data may include the following steps: querying whether the target roller is marked as an abnormal state based on the target ID information; if it is marked as an abnormal state, judging whether the target roller is abnormally damaged based on the installation time and theoretical life cycle of the target roller; in the abnormal damage state, generating an alarm message based on the target ID information, and sending the alarm message to the inspection personnel through the inspection equipment.

[0047] Specifically, in this embodiment, the roller operation parameters detected by the detection equipment and the historical data in the roller management data can be combined to determine whether the roller is in an abnormal state. That is, in this embodiment, the full life cycle management system also includes various types of information collection equipment, which are pre-installed at each group of rollers along the line or on the inspection equipment, and the multiple operating parameters of each group of rollers are detected by the information collection equipment. Then, based on the wireless connection established between the signal tag 10, the signal receiving device 20 and the background management server 30, the multiple operating parameters detected in real time are gradually sent to the background management server 30. Combined with the multiple operating parameters of the currently detected roller and the historical fault records, it is determined whether the roller is marked as an abnormal state.

[0048] Among them, various types of information collection equipment can be various types of sensors, cameras and other detection equipment, such as Figure 3 As shown, various sensors 40 can be installed at each group of rollers along the line. These sensors can be various types of detection equipment such as temperature sensors and vibration sensors to collect parameters such as the operating temperature and vibration amplitude of each group of rollers. Alternatively, information collection equipment such as a thermal imaging camera 50 and an audio collection device 60 can also be installed on the inspection robot to detect the operating parameters of multiple rollers within the working range in real time during the operation of the inspection robot.

[0049] For example, when the information collection device is a plurality of temperature sensors, each temperature sensor is installed at a corresponding group of rollers, and the temperature sensor is used to collect the operating temperature of the rollers. When the information collection device is a plurality of vibration sensors, each vibration sensor is installed at a corresponding group of rollers, and the vibration sensor is used to collect the vibration information of the rollers. In this way, whether the rollers are abnormal can be detected according to the operating temperature and vibration of the rollers.

[0050] When the information acquisition device is a thermal imaging acquisition device 50, the thermal imaging acquisition device is installed on the inspection robot. The thermal imaging acquisition device 50 can be a thermal imaging camera. The operating temperature of multiple groups of rollers within the working range of the signal receiving device 20 can be detected based on the images collected by the camera.

[0051] When the information collection device is an audio collection device 60, the audio collection device 60 is installed on the inspection robot, and the audio collection device is used to detect the working noise of multiple groups of rollers within the working range of the signal receiving device 20. According to the roller operation noise collected by the audio collection device 60, it can be detected whether the operation status of the roller is normal, for example, whether the rotation process is sequential, whether there are obstacles blocking the operation, etc.

[0052] Furthermore, in combination with the data collected by various types of information collection equipment, if it is determined that the current roller is marked as abnormal, the installation time and theoretical life cycle of the roller are used to determine whether the current equipment is a normal damage due to reaching the service life, or an abnormal damage caused by other reasons. If the time from the installation time to the current time is greater than or equal to the theoretical life cycle, it is determined to be normal damage; if the time from the installation time to the current time is greater than or equal to the theoretical life cycle, it is determined to be an abnormal damage caused by unexpected factors during operation.

[0053] Furthermore, according to the method in the above embodiment, the detection results of each group of rollers along the belt conveyor during each round of inspection can be obtained separately, including the detected operating parameters and whether the operating status is abnormal. Furthermore, the background management server 30 can record the operation management operations performed on each group of rollers, such as the replacement records of each roller. Then, the management data of each roller stored in the full life cycle management system is updated according to the various types of recorded data, so that subsequent detection and management can be performed in the same manner in subsequent inspection cycles. Until the roller is replaced after being damaged, the above-mentioned full life cycle management is performed on the replaced roller.

[0054] Therefore, the utility model carries out full-time supervision on each group of rollers along the belt conveyor, from their installation to damage, so as to realize all-round supervision on the rollers' service life cycle, and can monitor the operating status of the belts and rollers in real time, judge whether damage occurs, and record service life data and replacement data.

[0055] In summary, the full life cycle management system of the belt conveyor rollers in the embodiment of the utility model utilizes the wireless connection established by the RFID device to communicate by wireless radio frequency to transmit the full life cycle management data of the rollers. The utility model utilizes the characteristics of the RFID device such as simple installation, high stability and small size, which is convenient for installation on the rollers along the belt conveyor, and the size of the RFID card reader device is convenient for integration on the inspection equipment, so that it is easy to arrange the equipment in practical applications, reducing the difficulty of implementing supervision. Therefore, the utility model can ensure the safety and normal operation of the rollers, can carry out all-round supervision of the rollers' service life cycle, and can carry out real-time supervision of the entire process of the rollers from installation to damage, and realize the functions of tracing back the source of abnormal problems and constantly monitoring the operating status of the rollers. Improve the accuracy, real-time and comprehensiveness of roller life cycle management.
