Problems solved by technology

[0003] At present, the fault detection of sieve plates mainly relies on manual inspection, which relies on the subjective experience of personnel, and cannot form a rigorous basis for fault judgment. In most cases, early hidden faults cannot be found; secondly, manual inspection is not real-time and can only be inspected periodically. Troubleshooting is not timely enough; and manual inspection of multi-layer sieve plates is difficult and difficult to implement; finally, a complete life cycle management of sieve plate status cannot be established based on manual inspection, and there is a huge waste in the current fixed cycle replacement of sieve plates

Embodiment

[0045] like figure 1 As shown, the embedded sieve plate state monitoring device includes a power supply module for providing power supply, and also includes a state sensing module, the state sensing module is connected with a signal processing module, and the signal processing module is connected with a background management system through a communication module. , the background management system is connected with sieve plate operation equipment and alarm equipment;

[0046] The state sensing module is used to collect the operating state data of the sieve plate;

[0047] The signal processing module is used for analyzing and processing the collected operating state data of the sieve plate, and judging the fixing condition of the sieve plate;

[0048] The background management system is used for data traces and sending of relevant instructions;

Embodiment 2

[0056] A monitoring method for an embedded sieve plate state monitoring device applied to Embodiment 1, comprising the following steps:

[0057] Step 1: signal collection; in the step 1, the collected information includes triaxial acceleration and temperature.

[0058] Step 2: Use the time domain threshold detection algorithm, frequency domain power spectral density (PSD) analysis, and combine the adaptive filter algorithm to carry out adaptive evolution to determine whether the sieve plate is loose;

[0059] The second step includes the following sub-steps:

[0060] 1-1: Calculate time domain eigenvalues , its calculation formula is:

[0061] in is the peak instantaneous acceleration, is the effective value of acceleration, which reflects the degree to which the maximum amplitude deviates from the vibration center value, and the characteristic value will increase significantly when the sieve plate is loose;

[0062] 1-2: Time domain eigenvalues Corresponding contras...

Embodiment 3

[0079] On the basis of Example 1 and Example 2

[0080] For example, in actual operation, the effective value of the acceleration of the vibrating screen About 2.01g (g =9.8m / s²), the peak instantaneous acceleration during its normal operation is 2.8g (g =9.8m / s²), then calculate the time domain eigenvalue according to the formula is 1.393, calculated by the least mean square algorithm =1.775, then Srp=1.42, at this time Rp(1.393)<Srp(0.8*1.775), the device is running normally.

[0081] The power spectral density of the sieve plate is collected by a power spectral density measuring instrument, and the high / low frequency parts are integrated respectively with 80% of the frequency band broadband (WB) as the boundary, and the ratio is obtained. =352.66, output value after LMS adaptive filter =467.11. (352.66) (0.8*467.11), which means that the sieve plate is in normal working condition. The above conclusions are consistent with the status of the field equipment.

Description

technical field [0001] The invention relates to the technical field of sieve plate monitoring, in particular to an embedded sieve plate state monitoring device and a monitoring method thereof. Background technique [0002] At present, during the working process of the sieve machine, the sieve plate is affected by vibration and material interaction, and will loose and fall off failures. Once the sieve plate falls off, it will seriously affect the production. First of all, if the sieve plate falls off, it must be stopped immediately. There is no efficient treatment plan at this stage, and it mainly relies on manual cleaning; secondly, material accumulation will occur, causing chute blockage and belt damage; third, the cleaning work after the sieve plate falls off is easy to cause Personal injury. Therefore, it is of great practical significance to invent a device for real-time monitoring of the state of the sieve plate. [0003] At present, the fault detection of sieve plate...
