Install sensors for monitoring the operating status on the vibrating screen, track the operating conditions of the vibrating screen in real time, and then judge the health of the vibrating screen based on the monitored operating status data. In addition, the existing monitoring devices have the following disadvantages in use:

[0004] (1) The working environment of the vibrating screen is usually harsh, with adverse factors such as electromagnetic interference, vibration impact, etc. The wireless sensors in the prior art may have problems such as unstable signals or data distortion due to these external interferences. Summary of the invention

[0025] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2As shown, this embodiment proposes a real-time monitoring device for a vibrating screen, including a vibrating screen body 1, a Lora three-axis temperature vibration sensor 5, a receiver 6, a Lora uniaxial temperature vibration sensor 7 and a Lora receiver 8. The top of the vibrating screen body 1 is fixedly connected with a screen beam 3, the four bottom corners of the vibrating screen body 1 are respectively fixedly connected with a connecting seat 2, the top two sides of the screen beam 3 are respectively fixedly connected with an exciter 4, the number of the Lora three-axis temperature vibration sensors 5 is four, and the four Lora three-axis temperature vibration sensors 5 are respectively arranged on the top of the connecting seat 2, the number of the receivers 6 is two, and the two receivers 6 are respectively arranged at the centers of the two sides of the vibrating screen body 1, the number of the Lora uniaxial temperature vibration sensors 7 is two, and the two Lora uniaxial temperature vibration sensors 7 are respectively arranged on the top of the exciter 4, and the Lora receiver 8 is arranged on one side of the vibrating screen body 1.

[0028] Furthermore, four Lora three-axis temperature and vibration sensors 5 are used to collect data such as three-axis vibration acceleration, vibration frequency, vibration displacement and angle of the vibrating screen body 1 .

[0029] Furthermore, two Lora single-axis temperature and vibration sensors 7 are used to collect data such as temperature and acceleration of the exciter 4 .

[0030] Furthermore, the two receivers 6 are electrically connected to the Lora three-axis temperature vibration sensor 5 and the Lora single-axis temperature vibration sensor 7 respectively. The two receivers 6 are used to receive data from the Lora three-axis temperature vibration sensor 5 and the Lora single-axis temperature vibration sensor 7, and transfer the data to the PLC for processing.

[0031] Furthermore, the Lora receiver 8 collects key data such as resonance, eccentric load, amplitude, temperature and phase of the vibrating screen body 1 in real time. The Lora receiver 8 calculates the resonance, eccentric load and amplitude of the vibrating screen body 1 and the over-temperature of the vibrator 4 and generates a report.

[0032] Furthermore, the Lora receiver 8 can also upload the data results remotely, and view the health report and operation log of the vibrating screen body 1 in real time.

[0033] Furthermore, it also includes a local buzzer and a remote communication module. When abnormal data is monitored, such as the vibration parameters of the vibrating screen body 1 exceed the preset range or the temperature of the exciter 4 is too high, the system sends an alarm signal through the local buzzer and triggers a remote web page pop-up window through the remote communication module, reminding the equipment operation and maintenance personnel in real time to deal with the fault in time.

[0034] Furthermore, it also includes a data storage device, which is used to store historical monitoring data, analysis reports and operation and maintenance records of the vibrating screen body 1.

[0035] During specific use, in a certain collection, four Lora three-axis temperature and vibration sensors 5 measured the vibration acceleration of the X-axis to be 5g, the Y-axis to be 3g, the Z-axis to be 2g, the vibration frequency to be 15Hz, the vibration displacement to be 5mm, and the angular deflection to be less than 1°. Two Lora single-axis temperature and vibration sensors 7 monitored the temperature of the vibrator 4 to be 80°C. When the acceleration peak was 10g, the Lora receiver 8 collected the resonance frequency of the vibrating screen body 1 in real time at 16Hz. The eccentricity was determined by comparing the data differences of each sensor. If the difference exceeded 5%, it was regarded as eccentricity. The average amplitude was 4mm, and the relevant data results were calculated, including the medium resonance intensity level and the mild degree of eccentricity. Finally, a detailed monitoring report was generated, which included today's amplitude fluctuation range of 3-5mm, the average vibration frequency of 15Hz, the temperature of the vibrator 4 was stable, and no over-temperature phenomenon was found.

[0036] When abnormal data is detected, the vibration parameters of the vibrating screen body (1) exceed the preset range, the amplitude suddenly increases to 8mm, the temperature of the vibrator 4 continues to be higher than the safety threshold, and the temperature of the vibrator 4 is 90°C, the system will immediately trigger the local buzzer alarm and send an emergency notification to the operation and maintenance personnel through the remote communication module, such as sending a text message or triggering a remote web page pop-up window to remind them to take timely measures to deal with the fault. By analyzing historical data, the performance change pattern of the vibrating screen under specific working conditions can be discovered, so as to adjust the operating parameters in advance and avoid failures.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
